本發明的目的是提供一種上文所述類型的剪刀，該剪刀在提供簡單操作的同時提供精簡緊湊的結構。 It is an object of the present invention to provide a scissor of the type described above that provides a compact and compact structure while providing a simple operation.

根據本發明的剪刀的上述目的，通過提供一種覆蓋裝置來實現，該覆蓋裝置至少在關閉位置中橫向於第三樞軸線覆蓋下列元件的至少一者：第二樞軸承、第三樞軸承、第四樞軸承、鎖定裝置。 The above object of the scissors according to the invention is achieved by providing a covering device covering at least one of the following elements transversely to the third pivot axis, at least in the closed position: the second pivot bearing, the third pivot bearing, the first Four pivot bearings and locking devices.

由於覆蓋裝置的關係，由第二樞軸承，第三樞軸承和第四樞軸承構成的元件中的至少一個可以以受保護的方式配置。鎖定裝置也可以以受保護的方式佈置。 Due to the relationship of the covering means, at least one of the elements consisting of the second pivot bearing, the third pivot bearing and the fourth pivot bearing may be configured in a protected manner. The locking device can also be arranged in a protected manner.

由於鎖定裝置是受保護的定位，所述鎖定裝置可以更複雜地機械性的設計。因此可以實現簡化的操作，特別是剪刀可單手操作。 Since the locking device is a protected positioning, the locking device can be more complex and mechanically designed. So you can achieve simplified operation Work, especially scissors, can be operated with one hand.

此外，可以消除使用者的手被夾緊在鎖定裝置處的風險。 In addition, the risk of the user's hand being clamped at the locking device can be eliminated.

例如，覆蓋裝置可藉由限制第一手柄和第二手柄之間圍繞第二樞軸線的最大樞轉角度，來提供一止擋，以限制剪切頭的最大開口寬度。 For example, the covering device can provide a stop to limit the maximum opening width of the cutting head by limiting the maximum pivot angle between the first handle and the second handle about the second pivot axis.

覆蓋裝置也可以在鎖定位置中，在第一手柄和第二手柄之間也提供特定的最小間距。 The covering device can also provide a specific minimum spacing between the first handle and the second handle in the locked position.

根據本發明的剪刀可以以緊湊的方式設置，具有少量的部件。可以實現高剪切效率。 The scissors according to the invention can be arranged in a compact manner with a small number of components. High shear efficiency can be achieved.

由於第一，第二，第三和第四樞軸承的關係，本發明可提供具有高剪切效率的槓桿傳動的剪刀。 Due to the relationship of the first, second, third and fourth pivot bearings, the present invention can provide a lever-driven scissors with high shear efficiency.

根據本發明的剪刀還可以在保持裝置處(相對於第一手柄和第二手柄之間的樞轉角度)形成為具有相對小的開口寬度。因此，為使用者提供簡單的操作，因為手的相對小的移動即足以實現高剪切效率。覆蓋裝置可用於提供一止擋，以限制最大開口寬度。因此，剪刀的尺寸可以優化的方式確定，即使在保持裝置處具有小的開口寬度，因為覆蓋裝置是以一附加的結構元件加以提供。 The scissors according to the present invention may also be formed at the holding device (with respect to a pivoting angle between the first handle and the second handle) to have a relatively small opening width. Therefore, the user is provided with a simple operation because the relatively small movement of the hand is sufficient to achieve high shear efficiency. The cover device can be used to provide a stop to limit the maximum opening width. Thus, the size of the scissors can be determined in an optimized manner even with a small opening width at the holding device, since the covering device is provided with an additional structural element.

較佳者是，(i)覆蓋裝置固定到第一手柄並且第二手柄可相對於覆蓋裝置移動，或者(ii)覆蓋裝置固定到第二手柄，並且第一手柄可相對於覆蓋裝置移動。因此可以達成精簡結構的剪刀，特別是可單手操作以鎖定和解鎖關閉位置的剪刀。 Preferably, (i) the cover device is secured to the first handle and the second handle is moveable relative to the cover device, or (ii) the cover device is secured to the second handle and the first handle is moveable relative to the cover device. It is thus possible to achieve a streamlined scissors, in particular a scissors that can be operated with one hand to lock and unlock the closed position.

在一個示例性實施例中，覆蓋裝置在第一手柄相對於第二手柄的每個位置中覆蓋鎖定裝置和第二樞軸承。(i)當覆蓋裝置配置在第一手柄上時，覆蓋裝置還覆蓋第三樞軸承，或者(ii)當覆蓋裝置佈置在第二手柄上時，覆蓋裝置覆蓋第四樞軸承。特別地，如果例如在打開位置(具有最大打開角度)，第四樞軸承沒有被覆蓋裝置所覆蓋(當覆蓋裝置佈置在第一手柄上時)，或具有最大開口的第三樞軸承沒有被覆蓋(當覆蓋裝置佈置在第二手柄上時)，本發明可提供精簡的結構。 In an exemplary embodiment, the covering device covers the locking device and the second pivot bearing in each position of the first handle relative to the second handle. (i) When the covering device is disposed on the first handle, the covering device also covers the third pivot bearing, or (ii) when the covering device is disposed on the second handle, the covering device covers the fourth pivot bearing. In particular, if for example in the open position (with maximum opening angle), the fourth pivot bearing is not covered by the covering device (when the covering device is arranged on the first handle), or the third pivot bearing with the largest opening is not covered (When the covering device is disposed on the second handle), the present invention can provide a compact structure.

較佳者是，覆蓋裝置具有面向剪切頭的第一端和背離剪切頭部的第二端，其中覆蓋裝置在第二端比在第一端具有橫向於第三樞軸線的較大寬度。因此可以提供緊湊剪刀。 Preferably, the covering device has a first end facing the cutting head and a second end facing away from the cutting head, wherein the covering device has a larger width transverse to the third pivot axis at the second end than at the first end . Therefore, compact scissors can be provided.

特別地，如果覆蓋裝置的寬度在從第一端到第二端的方向上遞增，可提供緊湊的結構。因此，覆蓋裝置可以遵循剪刀的尺寸，而提供精簡緊湊的結構。 In particular, if the width of the covering device is increased in the direction from the first end to the second end, a compact structure can be provided. Therefore, the covering device can follow the size of the scissors to provide a compact and compact structure.

在關閉位置中，在第一手柄和第二手柄之間存在一間隙，如果覆蓋裝置通過第二端界定該間隙更佳。如此可在第一手柄和第二手柄之間提供最小間距，而該最小間距是由覆蓋裝置所預先限定的。舉例來說，因此可防止使用者的手指被夾住。 In the closed position, there is a gap between the first handle and the second handle, preferably if the covering device defines the gap through the second end. This provides a minimum spacing between the first handle and the second handle, which is predefined by the covering means. For example, it is thus possible to prevent the user's fingers from being caught.

更佳者是，在覆蓋裝置的第二端處的第一手柄和第二手柄之間的間距為至少0.8cm，特別是至少1cm。 More preferably, the spacing between the first handle and the second handle at the second end of the covering device is at least 0.8 cm, in particular at least 1 cm.

在一個實施例中，覆蓋裝置在平面圖中在平行於第三樞軸線的方向上具有三角形或梯形形狀。因此，可以最佳地跟隨剪刀的輪廓，而提供緊湊的結構。 In one embodiment, the covering device has a triangular or trapezoidal shape in a plan view parallel to the third pivot axis. therefore It can best follow the contour of the scissors and provide a compact structure.

較佳者是，覆蓋裝置包括至少一個蓋板。因此，鎖定裝置和/或一個或多個樞軸承可以被覆蓋，以便以簡單的方式加以保護。 Preferably, the covering means comprises at least one cover. Thus, the locking device and/or one or more pivot bearings can be covered for protection in a simple manner.

尤其特別有利的是，覆蓋裝置包括第一蓋板和間隔開的第二蓋板，第一手柄和第二手柄的一部件定位在第一蓋板和第二蓋板之間，其中尤其是，第一蓋板和第二蓋板至少大致彼此平行。因此可以以簡單的方式達成一外部覆蓋物，其中覆蓋物設置在剪刀的兩側的上。 It is particularly advantageous for the covering device to comprise a first cover and a second cover which are spaced apart, a component of the first handle and the second handle being situated between the first cover and the second cover, wherein, in particular, The first cover and the second cover are at least substantially parallel to each other. An external covering can thus be achieved in a simple manner, wherein the covering is arranged on both sides of the scissors.

較佳者是，第一剪切腿和第二剪切腿的開口係配置在第一蓋板和第二蓋板之間。剪切腿被引導通過相應的開口，其中該等剪切腿在第一樞軸承處彼此鉸接。第一樞軸承優選的設於覆蓋裝置的外部。 Preferably, the openings of the first shearing leg and the second shearing leg are disposed between the first cover and the second cover. The shearing legs are guided through respective openings, wherein the shearing legs are hinged to each other at the first pivot bearing. The first pivot bearing is preferably disposed outside of the covering device.

較佳者是，在鎖定裝置的操作元件上，在第一蓋板和第二蓋板之間，設置有一進入開口。因此，使用者可以簡單的從外部操作鎖定裝置。 Preferably, an access opening is provided between the first cover and the second cover on the operating element of the locking device. Therefore, the user can simply operate the locking device from the outside.

基於相同的原因，較佳者是，覆蓋裝置包括第一剪切腿穿過的第一開口，和/或覆蓋裝置包括第二剪切腿穿過的第二開口。因此，覆蓋裝置至少在關閉位置中可以覆蓋第三樞軸承和/或第四樞軸承。 For the same reason, it is preferred that the covering means comprises a first opening through which the first shearing leg passes and/or the covering means comprises a second opening through which the second shearing leg passes. Thus, the covering device can cover the third pivot bearing and/or the fourth pivot bearing at least in the closed position.

還較佳者是，覆蓋裝置包括用於接近鎖定裝置的操作元件的第三開口。 Still preferably, the covering means includes a third opening for accessing the operating element of the locking device.

在一個實施例中，操作元件穿過第三開口。因此，使用者可以從覆蓋裝置的外部接近鎖定裝置。因此提供了簡單的操作。例如，可以以簡單的方式提供單手操作的可能性。鎖定裝置也可以使用將剪刀固持在保持裝置中的同一手來操作。 In one embodiment, the operating element passes through the third opening. Therefore, the user can access the locking device from the outside of the covering device. Therefore, a simple operation is provided. For example, the order can be provided in a simple manner The possibility of hand operation. The locking device can also be operated using the same hand that holds the scissors in the holding device.

特別有利的是，如果(i)第一手柄或(ii)第二手柄的一止擋是配置或形成在覆蓋裝置上，通過該止擋，可限制第一手柄和第二手柄之間的最大開口寬度，從而限制剪切頭的開口寬度。這種止擋可以以簡單的方式提供。剪刀所需零件的數量可以最小化。通過為剪刀設定最大開口寬度，可確保高剪切效率；確保可提供切割刀片的充分重疊，以便防止輕切(nicking)的發生，並且在切割刀片和反向切割刀片(鄰接件)之間提供足夠的偏壓。 It is particularly advantageous if the stop between (i) the first handle or (ii) the second handle is configured or formed on the covering device, by which the maximum between the first handle and the second handle can be limited The width of the opening, thereby limiting the width of the opening of the cutting head. This stop can be provided in a simple manner. The number of parts required for the scissors can be minimized. High shear efficiency is ensured by setting the maximum opening width for the scissors; ensuring that sufficient overlap of the cutting blades is provided to prevent nicking from occurring and providing between the cutting blade and the reverse cutting blade (adjacent piece) Sufficient bias.

特別地，止擋配置在覆蓋裝置上，在面向剪切頭的第一端的區域中。止擋優選的配置在第二樞軸承附近，藉此提供了緊湊的結構。 In particular, the stop is arranged on the covering device in the region facing the first end of the cutting head. The stop is preferably disposed adjacent the second pivot bearing, thereby providing a compact construction.

特別較佳者是，覆蓋裝置形成或包括一殼體，其中配置有第一手柄的一部分，第二手柄的一部分，第一剪切腿的一部分，第二剪切腿的一部分，第三樞軸承和/或第四樞軸承和鎖定裝置，其中特別地，第二樞軸承也佈置在殼體中。因此，樞軸承可以以受保護的方式佈置。鎖定裝置可以以相對複雜的方式形成，以便能夠簡單地操作剪刀。舉例來說，可以為鎖定裝置提供一可移動元件，其中該可移動元件的軸承能以受保護的方式佈置在殼體中。 Particularly preferably, the covering device forms or comprises a housing in which a portion of the first handle, a portion of the second handle, a portion of the first shearing leg, a portion of the second shearing leg, a third pivot bearing And/or a fourth pivot bearing and locking device, wherein in particular the second pivot bearing is also arranged in the housing. Therefore, the pivot bearing can be arranged in a protected manner. The locking device can be formed in a relatively complicated manner in order to be able to operate the scissors simply. For example, a locking element can be provided with a movable element, wherein the bearing of the movable element can be arranged in the housing in a protected manner.

在一個示例性實施例中，提供有三角形區域，其作為各別的轉折點，在第二樞軸線，第三樞軸線和第四樞軸線上具有一點，其中覆蓋裝置至少在一側覆蓋三角形區域，且特別是在兩側覆蓋三角形區域，其中覆蓋物至少設於剪切頭的關閉位置中。因此提供了緊湊的結構，並且剪刀的相應部件以受保護的方式配置。 In an exemplary embodiment, a triangular region is provided as a separate turning point having a point on the second pivot axis, the third pivot axis and the fourth pivot axis, wherein the covering device covers at least one side The triangular region, and in particular the triangular regions are covered on both sides, wherein the covering is provided at least in the closed position of the cutting head. A compact structure is thus provided and the respective components of the scissors are configured in a protected manner.

較佳者是，鎖定裝置佈置在位於第一手柄或第二手柄上的殼體中，其中特別地，第三樞軸承和/或第四樞軸承設置在殼體中。 Preferably, the locking device is arranged in a housing on the first handle or the second handle, wherein in particular the third pivot bearing and/or the fourth pivot bearing are arranged in the housing.

由於鎖定裝置是定位在殼體中，可以以受保護的方式容納所述鎖定裝置。因此，例如與簡單的垂片相比，鎖定裝置可以以更複雜的方式形成。除了緊湊的結構之外，本發明還提供了簡單的操作，特別是單手操作剪刀的可能性。 Since the locking device is positioned in the housing, the locking device can be received in a protected manner. Thus, for example, the locking device can be formed in a more complicated manner than a simple tab. In addition to the compact construction, the present invention also provides for simple operation, particularly the possibility of operating the scissors with one hand.

較佳者是，殼體包括一進入開口，鎖定裝置的操作元件可通過該進入開口進入接近，特別是當操作元件穿過該進入開口時尤然。因此，使用者可以手動方式操作該操作元件，特別是使用固持剪刀的同一隻手，因此例如可以釋放或建立鎖定。 Preferably, the housing includes an access opening through which the operating element of the locking device can be accessed, particularly when the operating element passes through the access opening. Thus, the user can operate the operating element manually, in particular using the same hand holding the scissors, so that for example a lock can be released or established.

較佳者是，鎖定裝置的一可移動元件配置在三角形區域，該三角形區域作為各別的轉折點時，在第二樞軸線，第三樞軸線和第四樞軸線上包含有一點。因此提供了具緊湊結構的剪刀。 Preferably, a movable element of the locking device is disposed in the triangular region, the triangular region including a point on the second pivot axis, the third pivot axis and the fourth pivot axis as respective inflection points. Therefore, a scissors with a compact structure is provided.

較佳者是，如果鎖定裝置包含一可作為可移動元件的旋轉元件時，該旋轉元件係配置在三角形區域處。因此提供了簡單操作性，特別是單手操作的可能性以及緊湊的結構。例如在第一手柄和第二手柄之間，或在手柄和鉸接到另一手柄的剪切腿之間的鎖定可以以簡單的方式建立和釋放，特別是通過確實接合來建立和釋放。該鎖定再次鎖定剪切頭的關閉位置。 Preferably, if the locking device comprises a rotating element that can act as a movable element, the rotating element is disposed at the triangular region. This provides simple operability, especially the possibility of one-handed operation and a compact structure. For example, between the first handle and the second handle, or between the handle and the cutting leg hinged to the other handle, the lock can be simplified. The establishment and release of a single way, especially through the actual engagement to establish and release. This lock again locks the closed position of the cutting head.

較佳者是，旋轉元件設置在第三樞軸承或第四樞軸承上。因此提供了緊湊的結構。 Preferably, the rotating element is disposed on the third pivot bearing or the fourth pivot bearing. This provides a compact structure.

更佳者是，第三樞軸承或第四樞軸承為旋轉元件形成一旋轉軸承。因此可以將所需部件的數量保持為最小。 More preferably, the third pivot bearing or the fourth pivot bearing forms a rotary bearing for the rotating element. Therefore, the number of required components can be kept to a minimum.

特別有利的是，如果旋轉元件的旋轉軸線與第三樞軸線或第四樞軸線共軸，即可提供緊湊的結構。 It is particularly advantageous if a rotational axis of the rotary element is coaxial with the third pivot axis or the fourth pivot axis, providing a compact construction.

較佳者是，(i)當旋轉元件被配置在第二手柄上時，旋轉元件的一配對元件是配置或形成在第一手柄或第一剪切腿上，或者(ii)當所述旋轉元件設置在第一手柄上時，旋轉元件的一配對元件是配置或形成在第二手柄或第二剪切腿上。如此，可以簡單的方式直接或間接地(使用剪切腿)實現第一手柄和第二手柄之間的鎖定，通過該鎖定，可將剪切頭的關閉位置加以鎖定。 Preferably, (i) when the rotating element is disposed on the second handle, a mating element of the rotating element is configured or formed on the first handle or the first cutting leg, or (ii) when said rotating When the component is disposed on the first handle, a mating component of the rotating component is configured or formed on the second handle or the second cutting leg. In this way, the locking between the first handle and the second handle can be achieved directly or indirectly (using a cutting leg) in a simple manner by which the closed position of the cutting head can be locked.

特別有利的是，鎖定裝置包括旋轉元件和配對元件，其中(i)旋轉元件設置在第一手柄上，並且配對元件設置在第二手柄或第二剪切腿上，或者(ii)旋轉元件配置在第二手柄上且配對元件佈置在第一手柄上或第一剪切腿上，且其中鎖定裝置具有第一位置，在所述第一位置中該旋轉元件處於第一旋轉位置或處於第一旋轉位置範圍內，且在旋轉元件和配對元件之間建立確實鎖定連接，鎖定裝置具有第二位置，在該第二位置中，旋轉元件處於第二旋轉位置或第二旋轉位置範圍內，其中在旋轉元件和配對元件之間沒有確實接合，且在第一手柄和第二手柄的任何相對位置中也不能形成確實接合，且該鎖定裝置具有第三位置，在該第三位置中，旋轉元件是處於第三旋轉位置或第三旋轉位置範圍內，當第一手柄和第二手柄相對於彼此處於一特定位置或特定位置範圍內時，藉由將旋轉元件從第三旋轉位置或第三旋轉位置範圍，旋轉到第一旋轉位置或第一旋轉位置範圍即可到達鎖定裝置的第一位置。 It is particularly advantageous if the locking device comprises a rotary element and a mating element, wherein (i) the rotary element is arranged on the first handle and the counterpart element is arranged on the second handle or the second cutting leg, or (ii) the rotary element arrangement On the second handle and the mating element is disposed on the first handle or the first shearing leg, and wherein the locking device has a first position in which the rotating element is in the first rotational position or in the first position Within the range of rotational position, and establishing a positive locking connection between the rotating element and the mating element, the locking device has a second position in which the rotating element is in the second rotational position or the second rotational position, wherein There is no positive engagement between the rotating element and the mating element, and no positive engagement is made in any relative position of the first handle and the second handle, and the locking device has a third position in which the rotating element Is in the third rotational position or the third rotational position range, when the first handle and the second handle are in a specific position or a specific position range relative to each other, by rotating the rotating element from the third rotational position or the third rotation The position range is rotated to the first rotational position or the first rotational position range to reach the first position of the locking device.

由於提供有第一位置，第二位置和第三位置，除了可提供剪刀的緊湊結構之外，同時可提供簡單的操作性，特別是單手操作。 Since the first position, the second position and the third position are provided, in addition to the compact structure in which the scissors can be provided, simple operability can be provided at the same time, particularly one-handed operation.

在鎖定裝置的第一位置中，剪切頭的關閉位置特別地是藉由第一手柄和第二手柄之間的確實鎖定連接來鎖定；而在鎖定裝置的第二位置中沒有鎖定。剪切運動可以通過第一手柄和第二手柄圍繞第二樞軸線的相對樞轉來進行。 In the first position of the locking device, the closed position of the cutting head is in particular locked by a positive locking connection between the first handle and the second handle; and in the second position of the locking device there is no locking. The shearing motion can be performed by relative pivoting of the first handle and the second handle about the second pivot axis.

在鎖定裝置的第二位置中，可以藉由第二手柄相對於第一手柄的特定位置來實現旋轉元件的旋轉。因此提供了具有單手操作可能性，具簡單且緊湊結構的剪刀。在切割運動的情況下，本發明確保第一手柄和第二手柄之間的確實鎖定連接是不可能的。 In the second position of the locking device, rotation of the rotating element can be achieved by a particular position of the second handle relative to the first handle. Therefore, a scissors having a simple and compact structure with one-handed operation possibilities is provided. In the case of a cutting motion, the present invention ensures that a true locking connection between the first handle and the second handle is not possible.

由於提供有第二位置，鎖定裝置可以相對簡單的機械結構及緊湊尺寸形成，並且在這種情況下，鎖定裝置不會“干擾”剪切過程。 Due to the provision of the second position, the locking device can be formed in a relatively simple mechanical construction and in a compact size, and in this case the locking device does not "disturb" the shearing process.

舉例言之，通過使第二手柄盡可能地朝向第一手柄樞轉，然後使旋轉元件進入第三旋轉位置或第三旋轉位置範圍內，即可從第二位置開始簡單的到達第三位置。因此可以以簡單的方式建立確實鎖合聯接，並且因此也可以簡單的方式到達鎖定裝置的第一位置。 For example, by making the second handle as close as possible A handle is pivoted and then the rotating element is brought into the third rotational position or the third rotational position range to simply reach the third position from the second position. A positive locking connection can thus be established in a simple manner and can therefore also be reached in a simple manner in a first position of the locking device.

通過精簡緊湊的結構，本發明提供了高操作舒適性，特別是單手操作的可能性。 By streamlining a compact structure, the present invention provides high operational comfort, particularly the possibility of one-handed operation.

較佳者是，旋轉元件的止擋位元於其上配置有旋轉元件的手柄上。因此可以以簡單的方式限定第一旋轉位置。 Preferably, the stop element of the rotary element is on the handle on which the rotary element is disposed. The first rotational position can thus be defined in a simple manner.

當旋轉元件的操作元件，尤其是形成為凸耳或肋的操作元件，形成為止擋的配對元件時，即提供了緊湊的結構。 When the operating element of the rotary element, in particular the operating element formed as a lug or rib, forms a mating element of the stop gear, a compact construction is provided.

特別地，旋轉元件設置有摩擦接合裝置，該摩擦接合裝置使得旋轉元件的旋轉只需要最小的力；其中特別地，該最小力至少是旋轉元件的重量的力的五倍。因此對旋轉元件提供了具一特定剛度的旋轉，以確保旋轉元件自身不能旋轉，特別是不能由於受重量的力的影響而旋轉。使用者需進行干預(直接地或藉由適當的接觸手柄)才能產生旋轉。該最小力特別是至少為0.5N，或優選至少為1N，或更優選至少為5N。 In particular, the rotating element is provided with a frictional engagement means which requires only a minimum force for the rotation of the rotating element; wherein in particular the minimum force is at least five times the force of the weight of the rotating element. The rotation of the rotating element is thus provided with a specific stiffness to ensure that the rotating element itself cannot be rotated, in particular cannot be rotated by the force of the weight. The user needs to intervene (either directly or through a suitable contact handle) to produce rotation. The minimum force is in particular at least 0.5 N, or preferably at least 1 N, or more preferably at least 5 N.

特別有利的是，鎖定裝置形成為使得在鎖定裝置的第二位置中，配對元件所處的手柄被構造成作用在旋轉元件上，且旋轉元件的旋轉被執行。因此可以以簡單的方式，從可進行剪切運動的第二位置開始，到達對應於剪切頭的鎖定關閉位置的第一位置。在提供緊湊的結構的同時也提供簡單的操作。 It is particularly advantageous if the locking device is formed such that in the second position of the locking device the handle on which the mating element is located is configured to act on the rotating element and the rotation of the rotating element is performed. Thus, in a simple manner, starting from a second position at which the shearing movement can take place, a first position corresponding to the locked closed position of the cutting head can be reached. Providing compactness The structure also provides a simple operation.

基於相同的原因，較佳者是，鎖定裝置被建構成在第二位置中，旋轉元件和配對元件之間的確實鎖定連接是不可能的。因此可以執行剪切運動。 For the same reason, preferably, the locking device is constructed in the second position, and a true locking connection between the rotating element and the mating element is not possible. Therefore, a shearing motion can be performed.

還較佳者是，如果鎖定裝置被建構成從鎖定裝置的第二位置開始，只有通過使用者手動旋轉該旋轉元件到第三旋轉位置或第三旋轉位置範圍中，才能到達第三位置；特別是被建構成，僅通過樞轉其上佈置有配對元件的手柄(通過鉸接的剪切腿直接或間接的執行)，無法從第二位置到達第三位置。因此，在剪切運動的情況下，在保持裝置上不能達成鎖定，而提供了舒適的操作。 Still preferably, if the locking device is constructed to start from the second position of the locking device, the third position can only be reached by the user manually rotating the rotating member into the third rotational position or the third rotational position range; It is constructed to be able to reach the third position from the second position only by pivoting the handle on which the mating elements are arranged (either directly or indirectly through the articulated cutting legs). Therefore, in the case of the shearing motion, the locking cannot be achieved on the holding device, providing a comfortable operation.

較佳者是，從第一旋轉位置或第一旋轉位置範圍開始，藉由遞增旋轉角度可到達第二旋轉位置或第二旋轉位置範圍。且當從第二旋轉位置或第二旋轉位置範圍開始，藉由進一步增加旋轉角度可到達第三旋轉位置或第三旋轉位置範圍。且當從第三旋轉位置和/或第三旋轉位置範圍內開始時，可藉由減小旋轉角度而到達第一旋轉位置或第一旋轉位置範圍；其中特別地，第一旋轉位置或第一旋轉位置範圍是由止擋所預先界定。因此可提供緊湊的結構。 Preferably, the second rotational position or the second rotational position range is reached by increasing the rotational angle from the first rotational position or the first rotational position range. And when starting from the second rotational position or the second rotational position range, the third rotational position or the third rotational position range can be reached by further increasing the rotational angle. And when starting from the third rotational position and/or the third rotational position range, the first rotational position or the first rotational position range can be reached by reducing the rotation angle; wherein, in particular, the first rotational position or the first The range of rotational positions is predefined by the stop. Therefore, a compact structure can be provided.

較佳者是，旋轉元件包括一突起，且配對元件包括一凹部，突起可以***凹部中，其中，當突起***凹部中時，藉由確實接合鎖定關閉位置，和/或旋轉元件包括一凹部，且配對元件包括一銷，其中，當銷插入凹部中時，即建立確實鎖定連接。因此可以以簡單的方式實現第一手柄和第二手柄之間相對於彼此的樞轉遠離的確實鎖定聯接。 Preferably, the rotating element comprises a protrusion, and the mating element comprises a recess into which the protrusion can be inserted, wherein when the protrusion is inserted into the recess, the locking closed position is ensured by the engagement, and/or the rotating element comprises a recess, And the mating component includes a pin, wherein when the pin is inserted When entering the recess, a true locked connection is established. A positive locking coupling of the pivoting away from the first handle and the second handle relative to each other can thus be achieved in a simple manner.

如果配對元件中的凹部位於連接第三樞軸線和垂直於其的第四樞軸線的線上，則可提供緊湊的結構。 A compact structure can be provided if the recess in the mating element is on a line connecting the third pivot axis and a fourth pivot axis perpendicular thereto.

特別地，鎖定裝置的操作元件被佈置和形成為使得其可以藉由在保持裝置處固持剪刀的手來操作。因此，不論是鎖定或解鎖狀態，也提供可單手操作的剪刀。 In particular, the operating elements of the locking device are arranged and formed such that they can be operated by the hand holding the scissors at the holding device. Therefore, scissors that can be operated with one hand are provided regardless of the locked or unlocked state.

剪刀是例如形成為貫通式剪刀(run-through shears)。在貫通式剪刀的情況下，可以剪切工件，其中，可以在切割過程期間使用在上方(或下方)的保持手使保持裝置與工件間隔一距離定位。貫通式剪刀可以由剪切頭的剪切腿的相應具角度的結構所提供。 The scissors are formed, for example, as run-through shears. In the case of through-type scissors, the workpiece can be cut, wherein the holding device can be positioned at a distance from the workpiece during the cutting process using a holding hand above (or below) the cutting process. The through scissors can be provided by a correspondingly angled configuration of the shearing legs of the cutting head.

本發明優選地提供彈簧裝置，其彈簧力趨於使第一手柄和第二手柄圍繞第二樞軸線彼此遠離地樞轉。在切割過程的情況下，該彈簧裝置將第一手柄和第二手柄彼此遠離地推開，尤其是直到最大打開角度為止。當使用者將第一手柄和第二手柄推在一起以便進行剪切時，他必須克服該彈簧裝置的彈簧力。 The present invention preferably provides a spring device with a spring force that tends to pivot the first handle and the second handle away from each other about the second pivot axis. In the case of a cutting process, the spring means pushes the first handle and the second handle away from each other, in particular up to the maximum opening angle. When the user pushes the first handle and the second handle together for cutting, he must overcome the spring force of the spring device.

根據本發明的剪刀的一個示例性實施例，其在圖1至16中示出並且整體由標號10表示，特別地其是由掌上型剪刀所表示。它們包括保持裝置12，藉助於該保持裝置，剪刀10可以用一隻手保持和操作。 An exemplary embodiment of a scissors according to the present invention is shown in Figures 1 to 16 and is generally indicated by the numeral 10, in particular it is represented by a palm-type scissors. They comprise a holding device 12 by means of which the scissors 10 can be held and operated with one hand.

剪刀10特別是貫通式剪刀(run-through shears)。 The scissors 10 are in particular run-through shears.

在為剪刀10的情況下，為了切割工作，在一切割刀片和一配對切割刀片之間需要有壓力。 In the case of scissors 10, pressure is required between a cutting blade and a pair of cutting blades for cutting work.

保持裝置12包括第一手柄14和第二手柄16。 The retaining device 12 includes a first handle 14 and a second handle 16.

剪刀10還包含具有第一剪切腿20和第二剪切腿22的剪切頭18。 The scissors 10 also includes a shearing head 18 having a first shearing leg 20 and a second shearing leg 22.

第一剪切腿20和第二剪切腿22通過第一樞軸承24可樞轉地彼此鉸接。第一樞軸承24使得第一剪切腿20和第二剪切腿22可環繞第一樞軸線26相互樞轉(例如參見圖4)。 The first shearing leg 20 and the second shearing leg 22 are pivotally hinged to each other by a first pivot bearing 24. The first pivot bearing 24 allows the first shear leg 20 and the second shear leg 22 to pivot relative to each other about the first pivot axis 26 (see, for example, Figure 4).

第一手柄14和第二手柄16通過第二樞軸承28可樞轉地彼此鉸接。第二樞軸承28允許第一手柄14和第二手柄16之間可圍繞第二樞軸線30相互樞轉(參見圖4)。 The first handle 14 and the second handle 16 are pivotally hinged to each other by a second pivot bearing 28. The second pivot bearing 28 allows the first handle 14 and the first The two handles 16 are pivotable relative to each other about the second pivot axis 30 (see Figure 4).

第二樞軸線30平行於第一樞軸線26。 The second pivot axis 30 is parallel to the first pivot axis 26 .

第一手柄14和第一剪切腿20通過第三樞軸承32(例如參見圖3(b))彼此連接。第三樞軸承32允許第一剪切腿20和第一手柄24圍繞第三樞軸線34(例如參見圖4)的相互樞轉。 The first handle 14 and the first shearing leg 20 are connected to each other by a third pivot bearing 32 (see, for example, Fig. 3(b)). The third pivot bearing 32 allows the first shearing leg 20 and the first handle 24 to pivot relative to each other about a third pivot axis 34 (see, for example, Figure 4).

第三樞軸線34平行於第一樞軸線26。 The third pivot axis 34 is parallel to the first pivot axis 26 .

第二剪切腿22和第二手柄16通過第四樞軸承36(例如參見圖3(a)和3(b))彼此連接。第四樞軸承36允許第二剪切腿22和第二手柄16之間圍繞第四樞軸線38(例如參見圖5)的相對樞轉。 The second shearing leg 22 and the second handle 16 are connected to each other by a fourth pivot bearing 36 (see, for example, Figures 3(a) and 3(b)). The fourth pivot bearing 36 allows relative pivoting between the second shear leg 22 and the second handle 16 about the fourth pivot axis 38 (see, for example, Figure 5).

第四樞軸線38平行於第一樞軸線26。 The fourth pivot axis 38 is parallel to the first pivot axis 26.

第二樞軸承28比第三樞軸承32和第四樞軸承36更靠近剪切頭18。第二樞軸承28位於一連接線40與第一樞軸承24之間；該連接線40將第三樞軸承32和第四樞軸承36(圖8)垂直於第三樞軸線34的相連接。 The second pivot bearing 28 is closer to the shearing head 18 than the third pivot bearing 32 and the fourth pivot bearing 36. The second pivot bearing 28 is located between a connecting wire 40 and the first pivot bearing 24; the connecting wire 40 connects the third pivot bearing 32 and the fourth pivot bearing 36 (Fig. 8) perpendicular to the third pivot axis 34.

剪刀10通常由一握持手所保持，使得拇指附近的手的內側的區域抵靠第一手柄14放置。例如由塑膠材料製成的保持元件42配置在第一手柄14上。該保持元件包括一凸起部分44，可以接納握持手的拇指和食指之間的拇指鞍狀關節周圍的區域。 The scissors 10 are typically held by a gripping hand such that the area of the inside of the hand near the thumb rests against the first handle 14. A retaining element 42 made, for example, of a plastic material is disposed on the first handle 14. The retaining element includes a raised portion 44 that receives an area around the thumb saddle joint between the thumb and forefinger of the gripping hand.

第二手柄16通常通過施加握持手的前手指區域來抓握，使得所述手也部分地抓握第二手柄16。 The second handle 16 is typically grasped by applying a front finger area of the gripping hand such that the hand also partially grips the second handle 16.

例如由塑膠材料製成的保持元件46被配置在第二手柄16上。該保持元件46包括一凸起部分48。該凸起部分48係以肋或凸耳構形。 A retaining element 46, for example made of a plastic material, is arranged on the second handle 16. The retaining element 46 includes a raised portion 48. The convex The portion 48 is configured in the form of a rib or a lug.

在保持元件46上形成從凸起部分48跟隨的中空部49，例如，保持手的食指的前部區域可放置在該中空部內。 A hollow portion 49 following the convex portion 48 is formed on the holding member 46, for example, a front portion of the index finger holding the hand can be placed in the hollow portion.

當在切割過程中執行前進運動時，凸起部分48可防止保持手的滑動。 The raised portion 48 prevents the sliding of the hand from being maintained when the forward movement is performed during the cutting process.

在一個示例性實施例中(例如參見圖9)，第一手柄14包括第一部分50，其特別地是由金屬材料製成。因此，第二手柄16包括第二部分52，其特別地是由金屬材料製成。 In an exemplary embodiment (see, for example, Figure 9), the first handle 14 includes a first portion 50 that is specifically made of a metallic material. Thus, the second handle 16 includes a second portion 52, which is in particular made of a metallic material.

保持元件42是配置在第一部分50上。保持元件46配置在第二部分52上。 The retaining element 42 is disposed on the first portion 50. The retaining element 46 is disposed on the second portion 52.

在一個示例性實施例中，保持元件42被夾持到第一部分50上。保持元件46被夾持到第二部分52上。在一替代實施例中，保持元件42通過包覆成型第一部分50來產生。保持元件46通過包覆成型第二部分52而產生。 In an exemplary embodiment, the retaining element 42 is clamped onto the first portion 50. The retaining element 46 is clamped onto the second portion 52. In an alternate embodiment, the retaining element 42 is created by overmolding the first portion 50. The retaining element 46 is created by overmolding the second portion 52.

第一剪切腿20和第二剪切腿22通過第一樞軸承24彼此直接連接。剪刀10由第二樞軸承28分隔成一前部區域及一後部區域；剪切頭18被配置在該前部區域中，而保持元件42及46配置在該後部區域中。 The first shearing leg 20 and the second shearing leg 22 are directly connected to each other by a first pivot bearing 24. The scissors 10 are separated by a second pivot bearing 28 into a front region and a rear region; the cutting head 18 is disposed in the front region, and the retaining members 42 and 46 are disposed in the rear region.

第一樞軸承24位於前部區域中，並且第三樞軸承32和第四樞軸承36位於後部區域中。 The first pivot bearing 24 is located in the front region and the third pivot bearing 32 and the fourth pivot bearing 36 are located in the rear region.

剪切頭18可以通過第一手柄14和第二手柄16朝向彼此的相對運動而閉合，以便能夠執行切割動作。 The cutting head 18 can be closed by the relative movement of the first handle 14 and the second handle 16 towards each other to enable a cutting action to be performed.

第一剪切腿20包括第一區域54，通過該第一區域54，第一剪切腿20藉助第三樞軸承32安裝在第一手柄14上。第一區域54鄰接第二區域56，該第二區域56連接到第一區域54，並且通過於該區域，第一剪切腿20藉助第一樞軸承24鉸接到第二剪切腿22。 The first shearing leg 20 includes a first region 54 through which the first In the region 54, the first shearing leg 20 is mounted on the first handle 14 by means of a third pivot bearing 32. The first region 54 abuts the second region 56, which is connected to the first region 54, and by which the first shearing leg 20 is hinged to the second shearing leg 22 by means of the first pivot bearing 24.

第二區域56與連接到第二區域56的第三區域58相鄰接。 The second region 56 is adjacent to the third region 58 that is connected to the second region 56.

第三區域58橫向於第二區域56及橫向於第一區域54定向。 The third region 58 is oriented transverse to the second region 56 and transverse to the first region 54.

第三區域58包括用於在切割過程期間支撐工件的支撐件60(具體參見圖4)。 The third region 58 includes a support 60 for supporting the workpiece during the cutting process (see in particular Figure 4).

第二剪切頭22包括第一區域62，通過第一區域62，第二剪切頭22藉助第四樞軸承36鉸接到第二手柄16上。第一區域62鄰接有第二區域64，該第二區域64連接到第一區域62並且橫向於第一區域62定向。 The second cutting head 22 includes a first region 62 through which the second cutting head 22 is hinged to the second handle 16 by means of a fourth pivot bearing 36. The first region 62 abuts a second region 64 that is connected to the first region 62 and oriented transverse to the first region 62.

第二區域64鄰接有第三區域66，該第三區域66連接到第二區域64並且橫向於第二區域定向。 The second region 64 abuts a third region 66 that is connected to the second region 64 and oriented transverse to the second region.

切割刀片68被配置或形成在第三區域66上。切割刀片68配置在第二剪切腿22上。 The cutting blade 68 is configured or formed on the third region 66. The cutting blade 68 is disposed on the second shearing leg 22.

第一剪切腿20相對於第二剪切腿22形成的方式，使得切割刀片68能夠作用在擱置在支撐件60上的工件上。工件在切割過程時被支撐在支撐件60的支撐表面上。支撐件60在切割時充作支座。當第一手柄14朝向第二手柄16移動或者第二手柄16朝向第一手柄14移動時，切割刀片68即對工件作用。因此，第一剪切腿20相對於第二剪切腿22樞轉，而可以對工件進行切割。 The manner in which the first shearing leg 20 is formed relative to the second shearing leg 22 enables the cutting blade 68 to act on the workpiece resting on the support member 60. The workpiece is supported on the support surface of the support 60 during the cutting process. The support member 60 serves as a support when cutting. When the first handle 14 is moved toward the second handle 16 or the second handle 16 is moved toward the first handle 14, the cutting blade 68 acts on the workpiece. Therefore, the first shearing leg 20 pivots relative to the second shearing leg 22, and the workpiece can be cut.

由於第一剪切腿20是鉸接到第一手柄14並且第二剪切腿22是鉸接到第二手柄16，其中第一剪切腿20和第二剪切腿22又彼此鉸接，第一手柄14和第二手柄16彼此鉸接，故剪刀10具有槓桿傳動機能；該剪刀是具有槓桿傳動的貫通式剪刀。 Since the first shearing leg 20 is hinged to the first handle 14 and the second shearing leg 22 is hinged to the second handle 16, wherein the first shearing leg 20 and the second shearing leg 22 are hinged to each other, the first handle The 14 and the second handle 16 are hinged to each other so that the scissors 10 have a lever transmission function; the scissors are through-type scissors with a lever transmission.

在一個示例性實施例中，第一剪切腿20由金屬材料製成，且特別地為一體成形。特別地，第二剪切腿20也由金屬材料製成，並且特別地為一體成形。切割刀片68特別地在第二剪切腿22上一體形成。剪刀藉由適當的金屬加工製成。 In an exemplary embodiment, the first shearing leg 20 is made of a metallic material, and is in particular integrally formed. In particular, the second shearing leg 20 is also made of a metallic material and is in particular integrally formed. The cutting blade 68 is integrally formed in particular on the second shearing leg 22. Scissors are made by proper metal processing.

替代地，切割刀片也可以是固定到第二剪切腿的分離元件。 Alternatively, the cutting blade can also be a separate element that is fixed to the second shearing leg.

此外，也可設置成使得燒結盤69(圖16)在切割動作期間是配置在第一樞軸承24處，佈置在第一剪切腿20和第二剪切腿22相互接觸的區域中。 Furthermore, it may also be provided such that the sintering disk 69 (Fig. 16) is disposed at the first pivot bearing 24 during the cutting action, in a region where the first shearing leg 20 and the second shearing leg 22 are in contact with each other.

在一個示例性實施例中(參見圖16)，燒結盤69以其第二區域64坐落在第二剪切腿22上。燒結盤69具有一開口，第二樞軸承28的銷71可穿過該開口。 In an exemplary embodiment (see FIG. 16), the sintering disk 69 is seated on the second shearing leg 22 with its second region 64. The sintering disk 69 has an opening through which the pin 71 of the second pivot bearing 28 can pass.

特別地，該銷71不可旋轉地坐落於第一剪切腿20的第二區域56上。 In particular, the pin 71 is non-rotatably seated on the second region 56 of the first shearing leg 20.

彈簧裝置70被配置在保持裝置12上，特別是在第二樞軸承24(圖15)處。彈簧裝置70尤其包括一支腿彈簧或由一支腿彈簧形成。在以支腿彈簧構形的情況中，彈簧裝置70包含一具有多個匝的捲繞區域70a。該捲繞區域70a坐落於第二樞軸承28的銷70b上。 The spring device 70 is disposed on the retaining device 12, particularly at the second pivot bearing 24 (Fig. 15). The spring device 70 comprises in particular a leg spring or is formed by a leg spring. In the case of a leg spring configuration, the spring means 70 comprises a winding area 70a having a plurality of turns. The winding area 70a is seated on the pin 70b of the second pivot bearing 28.

第一腿70c和第二腿70d各自坐落於腿彈簧的捲繞區域上。第一腿70c被支撐在第一手柄14上。第二腿70d被支撐在第二手柄16上。 The first leg 70c and the second leg 70d are each seated on a winding area of the leg spring. The first leg 70c is supported on the first handle 14. The second leg 70d is supported on the second handle 16.

在一個實施例中，第一腿70c的支撐區域被配置在第一剪切腿20附近，設於第一手柄14上，而第二腿70d的支撐區域被配置在第二剪切腿22附近，設於第二手柄16上。 In one embodiment, the support region of the first leg 70c is disposed adjacent the first shear leg 20, disposed on the first handle 14, and the support region of the second leg 70d is disposed adjacent the second shear leg 22. It is disposed on the second handle 16.

彈簧裝置70被配置和形成為使得彈簧裝置的力趨於樞轉第一手柄14和第二手柄16，使得其等相互背離而達到最大打開角度。為了能夠樞轉第一手柄14和第二手柄16，使得其等朝向移向彼此，必須克服彈簧裝置70的彈簧力。 The spring device 70 is configured and formed such that the force of the spring device tends to pivot the first handle 14 and the second handle 16 such that they are offset from each other to a maximum opening angle. In order to be able to pivot the first handle 14 and the second handle 16 such that their orientations are towards each other, the spring force of the spring means 70 must be overcome.

為了限定最大打開角度，設置有一止擋，這將在下文進一步詳細描述。 In order to define the maximum opening angle, a stop is provided, which will be described in further detail below.

剪刀10具有一關閉位置(圖1，2，3(b)和圖4至8)，其中剪切頭18是閉合的；剪刀10的關閉位置對應於剪切頭18的關閉位置。 The scissors 10 has a closed position (Figs. 1, 2, 3(b) and Figs. 4 to 8) in which the cutting head 18 is closed; the closed position of the scissors 10 corresponds to the closed position of the cutting head 18.

在剪切頭18的關閉位置中，切割刀片68被第一剪切腿20的第三區域58覆蓋。在切割刀片68和支撐件60之間沒有可以放置工件的間隙。 In the closed position of the cutting head 18, the cutting blade 68 is covered by the third region 58 of the first shearing leg 20. There is no gap between the cutting blade 68 and the support member 60 where the workpiece can be placed.

剪刀10的關閉位置對應於保持裝置12的相應關閉位置，其中第一手柄14和第二手柄16相對於圍繞第二樞軸線30的樞轉具有最小的樞轉空間。 The closed position of the scissors 10 corresponds to a respective closed position of the retaining device 12, wherein the first handle 14 and the second handle 16 have a minimum pivoting space relative to pivoting about the second pivot axis 30.

為了固定剪切頭18的關閉位置，剪刀10包括一鎖定裝置72(具體參見圖8至14)。 To secure the closed position of the cutting head 18, the scissors 10 includes a locking device 72 (see in particular Figures 8 through 14).

鎖定裝置72是建構成使得第一手柄14和第二手柄16之間的上述最小樞轉位置是可鎖定的，該鎖定因此確保剪切頭18的關閉位置。 The locking device 72 is constructed such that the aforementioned minimum pivotal position between the first handle 14 and the second handle 16 is lockable, which thus ensures the closed position of the cutting head 18.

鎖定裝置72包括一旋轉元件74和一配對元件76。 The locking device 72 includes a rotating element 74 and a mating element 76.

在所示的示例性實施例中，旋轉元件74可旋轉地配置在第一手柄14上。配對元件76固定地連接到第二手柄16。 In the exemplary embodiment shown, the rotating element 74 is rotatably disposed on the first handle 14. The mating component 76 is fixedly coupled to the second handle 16.

原則上，動態反轉也是可能的，其中相應的旋轉元件被配置在第二手柄上，且配對元件配置在第一手柄(或第一剪切腿；參見圖17，其中顯示此動態反轉)。 In principle, dynamic inversion is also possible, in which the respective rotating element is arranged on the second handle and the mating element is arranged on the first handle (or the first cutting leg; see Figure 17, which shows this dynamic inversion) .

旋轉元件74可旋轉地圍繞旋轉軸線80安裝在旋轉軸承78上。 Rotating element 74 is rotatably mounted on rotary bearing 78 about axis of rotation 80.

在一個示例性實施例中，旋轉軸承78由第三樞軸承32形成，並且旋轉軸線80與第三樞軸線34同軸。 In an exemplary embodiment, the rotary bearing 78 is formed by a third pivot bearing 32 and the axis of rotation 80 is coaxial with the third pivot axis 34.

旋轉元件74定位在第一手柄14上，在保持元件42外部。 The rotating element 74 is positioned on the first handle 14 outside of the retaining element 42.

一摩擦接合裝置與旋轉軸承78相聯接且確保旋轉元件74“剛性地”旋轉。該摩擦接合裝置是例如通過按壓配合和/或適當形成的滑動表面來實現，以確保可大幅度的避免旋轉元件74，例如由於其重量的力的作用而獨立旋轉的風險。 A frictional engagement device is coupled to the rotary bearing 78 and ensures that the rotating element 74 rotates "rigidly". The frictional engagement means is realized, for example, by a press fit and/or a suitably formed sliding surface to ensure that the rotational element 74 can be largely avoided, for example, the risk of independent rotation due to the force of its weight.

特別地，特定的最小力對於旋轉元件74的旋轉是必要的，並且該特定的最小力顯著大於旋轉元件74的重量的力。 In particular, a particular minimum force is necessary for the rotation of the rotating element 74, and this particular minimum force is significantly greater than the weight of the rotating element 74.

舉例言之，旋轉元件74的旋轉所需的力至少是旋轉元件74的重量的力的五倍。例如，該最小力至少為0.5N，且優選地至少為1N，更優選的至少為5N。 For example, the force required to rotate the rotating element 74 is at least five times the force of the weight of the rotating element 74. For example, the minimum force is at least 0.5 N, and preferably at least 1 N, more preferably at least 5 N.

為了實現旋轉元件74的旋轉，在正常切割過程的情況下，適當的使用者操作旋轉元件74通常是需要的，或者也可以通過保持裝置12施加適當的力來達成。因此可大幅避免了旋轉元件74的不經意的或獨立的旋轉。 In order to effect rotation of the rotating element 74, in the case of a normal cutting process, it is generally desirable for the appropriate user to operate the rotating element 74, or it may be achieved by the application device 12 applying a suitable force. Unintentional or independent rotation of the rotating element 74 can thus be substantially avoided.

由於設置了摩擦接合裝置，造就了剪刀10的簡單結構，所需的部件也可極小化。 Since the frictional engagement means is provided, the simple structure of the scissors 10 is achieved, and the required components can be minimized.

基本上，也可通過一彈簧裝置來彈簧輔助旋轉元件74，該彈簧裝置傾向於將旋轉元件74壓入一止動位置，其中，然後需施加一力來抵抗彈簧裝置的力，以將旋轉元件引導離開該止動位置。 Basically, the rotating element 74 can also be spring-assisted by a spring means which tends to press the rotating element 74 into a stop position, wherein a force is then applied to resist the force of the spring means to rotate the element Guide away from the stop position.

配對元件76位於第二手柄16上，在保持元件46的外部。 The mating element 76 is located on the second handle 16 outside of the retaining element 46.

在一個實施例中，配對元件76位於第三樞軸線34和第四樞軸線38之間的連接線40上；上文所述的一個實施例中的旋轉軸線80與第三樞軸線34重合。 In one embodiment, the mating element 76 is located on the connecting line 40 between the third pivot axis 34 and the fourth pivot axis 38; the rotational axis 80 in one of the embodiments described above coincides with the third pivot axis 34.

旋轉元件74具有一主體82，主體82包括一盤片段84。例如，操作元件86一體地配置在盤片段84上，且特別地形成為凸耳或肋，且坐落於盤片段84上，操作元件86以橫向於盤片段84的方式突出。 The rotating element 74 has a body 82 that includes a disk segment 84. For example, the operating element 86 is integrally disposed on the disk segment 84 and is particularly formed as a lug or rib and sits on the disk segment 84 with the operating element 86 projecting transversely to the disk segment 84.

使用者可以借助於操作元件86主動地實施旋轉元件74的旋轉，特別是使用手將剪刀10保持在保持裝置12上。旋轉元件74還具有一突出元件88，其連接到盤片段84，且特別地是一體的連接。突出元件88具有一突出部90。突出部90構建成使得凹部92是設於突出部90和位於所述突出部外方的突出元件88之間。凹部具有一由相對的壁96,98所界定的基部94。壁96,98連接到基部94。壁96,98橫向於基部94定向，例如垂直定向。在此，壁98形成突起90的外側。 The user can actively implement the rotation of the rotary element 74 by means of the operating element 86, in particular using the hand to hold the scissors 10 on the holding device 12. The rotating element 74 also has a protruding element 88 that is coupled to the disk Fragment 84, and in particular an integral connection. The protruding element 88 has a projection 90. The protrusion 90 is constructed such that the recess 92 is provided between the protrusion 90 and the protruding element 88 located outside the protrusion. The recess has a base 94 defined by opposing walls 96, 98. The walls 96, 98 are connected to the base 94. The walls 96, 98 are oriented transverse to the base 94, such as vertically oriented. Here, the wall 98 forms the outer side of the protrusion 90.

突起90具有一端面100，端面100鄰接壁98並與其相連接。壁98被配置成與端面100成一銳角，例如在40°至60°的範圍。 The projection 90 has an end face 100 which abuts the wall 98 and is connected thereto. The wall 98 is configured to form an acute angle with the end face 100, such as in the range of 40° to 60°.

端面100連接到一下側102，其中下側102橫向地且至少為大致垂直於端面100定向。下側102特別是平坦的且併入盤片段84內。 The end face 100 is connected to the lower side 102, wherein the lower side 102 is oriented transversely and at least substantially perpendicular to the end face 100. The lower side 102 is particularly flat and incorporated into the disk segment 84.

下側102面向保持裝置12的下端104，該下端背離剪切頭18。 The lower side 102 faces the lower end 104 of the retaining device 12, which is facing away from the cutting head 18.

第二手柄16上的配對元件76包括一凹部106。 The mating component 76 on the second handle 16 includes a recess 106.

凹部106具有一基部108，相對的壁110,112從基部108突出。 The recess 106 has a base 108 from which the opposing walls 110, 112 protrude.

壁110形成在銷114處。 Wall 110 is formed at pin 114.

銷114構建成使得其可以***旋轉元件74中的凹部92內。配對元件76中的凹部106構建成使得旋轉元件74的突起90可***其中。 The pin 114 is constructed such that it can be inserted into the recess 92 in the rotating element 74. The recess 106 in the mating element 76 is constructed such that the protrusion 90 of the rotating element 74 can be inserted therein.

配對元件76具有一壁116(參見圖11)，其也是外壁銷114。配對元件76及因此第二手柄16可以經由壁116作用在旋轉元件74上，且可以引起旋轉元件74旋轉。這將在下文中進一步詳細地解釋。 The mating component 76 has a wall 116 (see FIG. 11) which is also the outer wall pin 114. The mating element 76 and thus the second handle 16 can act on the rotating element 74 via the wall 116 and can cause the rotating element 74 to rotate. This will be explained in further detail below.

一止擋122設置在第一手柄14上並且限制旋轉元件74在旋轉方向120上的旋轉運動。 A stop 122 is disposed on the first handle 14 and limits rotational movement of the rotating member 74 in the rotational direction 120.

止擋122例如可藉由一覆蓋裝置124的適當支撐表面來形成。這將在下麵進一步詳細地解釋。 The stop 122 can be formed, for example, by a suitable support surface of the cover device 124. This will be explained in further detail below.

用於止擋122的配對元件是在旋轉元件74上的操作元件86。 The mating element for the stop 122 is the operating element 86 on the rotating element 74.

通過將操作元件86與止擋122相並置，對旋轉元件74提供了一受限定的第一旋轉位置126(圖10)。通過第二手柄16的相應定位，可到達鎖定裝置72的第一位置128(圖10)，在該位置中，旋轉元件74是處於第一旋轉位置126，且旋轉元件74的突起90被***凹部106內。第二手柄16的配對元件76的銷114***旋轉元件74中的凹部92內。 By aligning the operating member 86 with the stop 122, the rotating member 74 is provided with a defined first rotational position 126 (Fig. 10). By the corresponding positioning of the second handle 16, the first position 128 (Fig. 10) of the locking device 72 can be reached, in which the rotating element 74 is in the first rotational position 126 and the projection 90 of the rotating element 74 is inserted into the recess 106 inside. The pin 114 of the mating element 76 of the second handle 16 is inserted into the recess 92 in the rotating element 74.

因此，旋轉元件74以確實鎖定的方式耦合到配對元件76上，相對於第一手柄14和第二手柄16圍繞第二樞軸線30遠離彼此的樞軸；第一手柄14和第二手柄16相對於彼此的對應位置藉由旋轉元件74和配對元件76(圖10)彼此鎖定，且彈簧裝置70不能使手柄14，16樞轉遠離對方。剪切頭18因此被鎖定在其關閉位置，且該關閉位置通過鎖定裝置72來鎖定。由於第一手柄14和第二手柄16之間的確實鎖定連接，保持裝置12及因此剪切頭18不能僅藉由樞轉第一手柄14和第二手柄16沿樞軸線30彼此遠離而加以打開。 Thus, the rotating element 74 is coupled to the mating element 76 in a positively locking manner relative to the pivot of the first handle 14 and the second handle 16 about the second pivot axis 30 away from each other; the first handle 14 and the second handle 16 are opposite The respective positions of each other are locked to each other by the rotating member 74 and the mating member 76 (Fig. 10), and the spring device 70 cannot pivot the handles 14, 16 away from each other. The cutting head 18 is thus locked in its closed position and the closed position is locked by the locking device 72. Due to the positive locking connection between the first handle 14 and the second handle 16, the retaining device 12 and thus the cutting head 18 cannot be opened only by pivoting the first handle 14 and the second handle 16 away from each other along the pivot axis 30. .

為了借助於鎖定裝置72來克服鎖定，使用者必須施加一力130(圖11)到旋轉元件74上，特別是施加到操作元件86上。該力必須使得旋轉元件74相對於旋轉方向120沿相反方向132旋轉。突出部90因此可離開凹部106，銷114可離開凹部92。旋轉元件74與配對元件76之間的確實連接即被克服，而第一手柄14和第二手柄16可以圍繞第二樞軸線30彼此樞轉遠離。剪切頭18因此可以被打開。 In order to overcome the locking by means of the locking device 72, the user must apply a force 130 (Fig. 11) to the rotating element 74, in particular to On operating element 86. This force must cause the rotating element 74 to rotate in the opposite direction 132 relative to the direction of rotation 120. The projection 90 can thus exit the recess 106 and the pin 114 can exit the recess 92. The exact connection between the rotating element 74 and the mating element 76 is overcome, and the first handle 14 and the second handle 16 can pivot away from each other about the second pivot axis 30. The cutting head 18 can thus be opened.

如果第一手柄14和第二手柄16圍繞第二樞軸線30(圖12和13)朝向彼此樞轉，但是在旋轉元件74和配對元件76之間沒有形成確實接合，則鎖定裝置72隨後即位於第二位置134(圖12和13)。 If the first handle 14 and the second handle 16 pivot towards each other about the second pivot axis 30 (Figs. 12 and 13), but no positive engagement is formed between the rotating element 74 and the mating element 76, the locking device 72 is then located Second position 134 (Figs. 12 and 13).

在鎖定裝置72的第二位置134中，配對元件76可以經由其壁116作用在旋轉元件74上，且這樣做時可以特別地作用在突起90上。尤其是，配對元件76可以作用在突出90的端面100上。 In the second position 134 of the locking device 72, the mating element 76 can act on the rotating element 74 via its wall 116 and in doing so can act particularly on the protrusion 90. In particular, the mating element 76 can act on the end face 100 of the projection 90.

如果第二手柄16朝向第一手柄14樞轉，則壁116接觸旋轉元件74。藉由使第二手柄16進一步朝向第一手柄14樞轉，可使旋轉元件74沿相反方向132旋轉。在此處，在旋轉元件74和配對元件76之間沒有形成確實接合，也就是說沒有產生鎖定。 If the second handle 16 pivots toward the first handle 14, the wall 116 contacts the rotating element 74. By pivoting the second handle 16 further toward the first handle 14, the rotating element 74 can be rotated in the opposite direction 132. Here, no positive engagement is formed between the rotating element 74 and the mating element 76, that is to say no locking is produced.

旋轉元件74可以藉由第二手柄16從第一旋轉位置126開始進入第二旋轉位置或第二旋轉位置範圍136，且相對於第一旋轉位置126，在反向132上遞增旋轉角度。 The rotating element 74 can be moved from the first rotational position 126 into the second rotational position or the second rotational position range 136 by the second handle 16, and the rotational angle is incremented in the reverse direction 132 relative to the first rotational position 126.

在鎖定裝置72的第二位置134的第二旋轉位置範圍136內，原則上旋轉元件74的旋轉運動是可能的，而不會在配對元件76之間形成確實鎖定連接。 In the second rotational position range 136 of the second position 134 of the locking device 72, in principle a rotational movement of the rotary element 74 is possible, There is no positive locking connection between the mating elements 76.

可以通過關閉保持裝置12來執行切割運動，而不存在任何鎖定。 The cutting motion can be performed by closing the holding device 12 without any locking.

當第二手柄16朝向第一手柄114移動時，配對元件76導致旋轉元件74在第二旋轉位置範圍136內的旋轉。 When the second handle 16 is moved toward the first handle 114, the mating element 76 causes rotation of the rotating element 74 within the second rotational position range 136.

鎖定裝置72還具有第三位置138(圖14)。在第三位置138中，旋轉元件74是處於第三旋轉位置140或處於第三旋轉位置範圍內。旋轉元件74的第三旋轉位置140可通過使用者施加力142來到達。在第三旋轉位置140中，旋轉元件74所處的位置是使得其能夠與配對元件76成確實鎖定連接的位置。 The locking device 72 also has a third position 138 (Fig. 14). In the third position 138, the rotating element 74 is in the third rotational position 140 or in the third rotational position range. The third rotational position 140 of the rotating element 74 can be reached by a user applying a force 142. In the third rotational position 140, the rotational element 74 is in a position such that it can be in a positively locking connection with the mating element 76.

在鎖定裝置72的第三位置138中，第二手柄16所處的位置是使得突起90可以進入凹部106內，且銷114可以進入凹部92內(圖14)。 In the third position 138 of the locking device 72, the second handle 16 is positioned such that the projection 90 can enter the recess 106 and the pin 114 can enter the recess 92 (Fig. 14).

從第三旋轉位置140或第三旋轉位置範圍開始，使用者可以以克服摩擦接合裝置的摩擦力的方式將旋轉元件74沿旋轉方向120旋轉到第一旋轉位置126。從而達到鎖定裝置72的第一位置128(參見圖10)。 Starting from the third rotational position 140 or the third rotational position range, the user can rotate the rotational element 74 in the rotational direction 120 to the first rotational position 126 in a manner that overcomes the frictional force of the frictional engagement device. Thereby the first position 128 of the locking device 72 is reached (see Figure 10).

具有旋轉元件74和配對元件76的鎖定裝置72的尺寸是設計成使得僅通過相對於第一手柄14樞轉第二手柄16是不能達到第三旋轉位置140的。旋轉元件74不是被構造成僅僅藉由配對元件76對旋轉元件74作用即可進入其第三旋轉位置140。為了實現這一點，使用者必須在旋轉元件74處，特別是在操作元件86處施加力142。因此，作為用於鎖定關閉位置(作為鎖定裝置72的第一位置128的起始位置)的起始位置的第三旋轉位置140，不能僅藉將保持裝置12的手柄14,16沿第二樞軸線30樞轉即可達到，如在切割運動的情形下所發生者。 The locking device 72 having the rotating element 74 and the mating element 76 is sized such that the third rotational position 140 cannot be reached by merely pivoting the second handle 16 relative to the first handle 14. The rotating element 74 is not configured to enter its third rotational position 140 by merely acting on the rotating element 74 by the mating element 76. In order to achieve this, the user must apply a force 142 at the rotating element 74, particularly at the operating element 86. therefore As the third rotational position 140 for locking the starting position of the closed position (as the starting position of the first position 128 of the locking device 72), the handles 14, 16 of the holding device 12 cannot be used only along the second pivot axis 30 pivoting can be achieved, as in the case of cutting motion.

剪刀10在第一手柄14和第二手柄16上具有三角形區域144。該三角形區域144具有在第二樞軸線30，第三樞軸線34和第四樞軸線38上具有點，作為各別的轉折點。 The scissors 10 have a triangular region 144 on the first handle 14 and the second handle 16. The triangular region 144 has points on the second pivot axis 30, the third pivot axis 34 and the fourth pivot axis 38 as respective inflection points.

三角形區域144係由第二樞軸承28，第三樞軸承32和第四樞軸承36所界定為轉折區域。 The triangular region 144 is defined by the second pivot bearing 28, the third pivot bearing 32 and the fourth pivot bearing 36 as a turning region.

覆蓋裝置124配置在該三角形區域144上。 Covering device 124 is disposed on the triangular region 144.

在所示的示例性實施例中，覆蓋裝置124是固定地連接到第一手柄14。由於其可樞轉性，第二手柄16可相對於覆蓋裝置124(參見圖3(a))移動。 In the exemplary embodiment shown, the cover device 124 is fixedly coupled to the first handle 14. Due to its pivotability, the second handle 16 is movable relative to the cover device 124 (see Figure 3(a)).

覆蓋裝置124在橫向於第三樞軸線34的方向，在外側覆蓋鎖定裝置72，第二樞軸承28和第三樞軸承32。 The cover means 124 covers the locking means 72, the second pivot bearing 28 and the third pivot bearing 32 on the outside in a direction transverse to the third pivot axis 34.

在剪刀10的關閉位置中，覆蓋裝置124也橫向於第三樞軸線34(參見圖3(a)和3(b))向外覆蓋第四樞軸承36。 In the closed position of the scissors 10, the cover means 124 also laterally covers the fourth pivot bearing 36 transversely to the third pivot axis 34 (see Figures 3(a) and 3(b)).

因此，鎖定裝置72和相應的樞軸承以受保護的方式配置。 Thus, the locking device 72 and the corresponding pivot bearing are configured in a protected manner.

在所示的示例性實施例中，在剪切頭18呈現最大開口寬度的打開位置中(參見圖3(a))，第四樞軸承36是擱置於覆蓋裝置124的外部。 In the illustrated exemplary embodiment, in the open position in which the cutting head 18 exhibits a maximum opening width (see FIG. 3(a)), the fourth pivot bearing 36 rests on the exterior of the covering device 124.

在圖3(b)中，樞軸承28，38，36的顯示是為了說明的目地。它們被覆蓋裝置124(參見圖1)所隱藏。 In Figure 3(b), the pivot bearings 28, 38, 36 are shown for illustrative purposes. They are hidden by the overlay device 124 (see Figure 1).

覆蓋裝置被定位在保持元件42外方的第一部分50的第一手柄14上。第二手柄16的保持元件46係位於覆蓋裝置124的外方。 The covering device is positioned on the first handle 14 of the first portion 50 outside of the retaining element 42. The retaining element 46 of the second handle 16 is located outside of the covering device 124.

覆蓋裝置124包括第一蓋板146和第二蓋板148。第一蓋板146和第二蓋板148彼此間隔開並且配置在第一手柄14的彼此背離的側面上。 The cover device 124 includes a first cover 146 and a second cover 148. The first cover plate 146 and the second cover plate 148 are spaced apart from each other and are disposed on sides of the first handle 14 that face away from each other.

第一蓋板146和/或第二蓋板148具有梯形形狀，其具有面向剪切頭18的第一端150，和面向保持裝置12的下端104，或遠離第一端150的第二端152。 The first cover plate 146 and/or the second cover plate 148 have a trapezoidal shape with a first end 150 facing the cutting head 18, and a lower end 104 facing the retaining device 12, or a second end 152 remote from the first end 150. .

在第一手柄14的保持元件42和第二手柄16的保持元件46之間存有一間隙154。當第一手柄14和第二手柄16沿第二樞軸線30樞轉而遠離彼此時，該間隙154變得更大。在剪切頭18的關閉位置中，第一手柄14和第二手柄16之間的間隙154為最小間隔尺寸。 A gap 154 is present between the retaining element 42 of the first handle 14 and the retaining element 46 of the second handle 16. The gap 154 becomes larger as the first handle 14 and the second handle 16 pivot along the second pivot axis 30 away from each other. In the closed position of the cutting head 18, the gap 154 between the first handle 14 and the second handle 16 is a minimum spacing dimension.

覆蓋裝置124藉由其蓋板146,148在其第二端152處界定間隙154。覆蓋裝置124和覆蓋板146,148的一區域的寬度156(該寬度界定間隙154)(見圖2)至少為0.8cm，特別是至少為1cm。 Covering device 124 defines a gap 154 at its second end 152 by its cover plates 146, 148. The width 156 of the region of the covering means 124 and the cover sheets 146, 148 (the width defining the gap 154) (see Fig. 2) is at least 0.8 cm, in particular at least 1 cm.

因此可以保護使用者的手免受擠壓。第一手柄14和第二手柄16之間的間隙154的最小間距在一定程度上由覆蓋裝置124所預先界定，且在此情形下是由其寬度156所預先界定。 Therefore, the user's hand can be protected from squeezing. The minimum spacing of the gap 154 between the first handle 14 and the second handle 16 is somewhat pre-defined by the covering means 124 and in this case is predefined by its width 156.

在此，蓋板146,148的寬度158(圖2)從第一端 150朝向第二端152的方向160上變大。 Here, the width 158 (Fig. 2) of the cover plates 146, 148 is from the first end 150 becomes larger in the direction 160 toward the second end 152.

在一個示例性實施例中，第一蓋板146和第二蓋板148通過一側壁162彼此連接。 In an exemplary embodiment, the first cover 146 and the second cover 148 are connected to each other by a side wall 162.

覆蓋裝置124因此形成殼體164。 The cover device 124 thus forms a housing 164.

第一手柄14在保持元件42外部的一區域，第二手柄16在保持元件46外部的一區域，第三樞軸承32和第二樞軸軸承28被配置在殼體164的內部，位於第一蓋板146和第二蓋板148之間。 The first handle 14 is in an area outside the retaining member 42, the second handle 16 is in an area outside the retaining member 46, and the third pivot bearing 32 and the second pivot bearing 28 are disposed inside the housing 164, at the first Between the cover plate 146 and the second cover plate 148.

第一剪切腿20的一部分和第二剪切腿22的一部分也配置在殼體164內，位於第一蓋板146和第二蓋板148之間。 A portion of the first shearing leg 20 and a portion of the second shearing leg 22 are also disposed within the housing 164 between the first cover plate 146 and the second cover plate 148.

鎖定裝置72也配置在殼體164內，位於第一蓋板146和第二蓋板148之間。 The locking device 72 is also disposed within the housing 164 between the first cover 146 and the second cover 148.

第四樞軸承36至少在剪刀10的關閉位置中是配置在殼體164內，在第一蓋板146和第二蓋板148之間。 The fourth pivot bearing 36 is disposed within the housing 164 at least between the first cover 146 and the second cover 148 in the closed position of the scissors 10.

覆蓋裝置124的殼體164包括第一開口166，其特別地為槽的形式。第一剪切腿20貫穿側壁162中的此第一開口166。這裡，第一開口166係構成為使得第一剪切腿20在其樞轉運動中可相應地圍繞第三樞軸線34移動。 The housing 164 of the cover device 124 includes a first opening 166, particularly in the form of a slot. The first shear leg 20 extends through this first opening 166 in the sidewall 162. Here, the first opening 166 is configured such that the first shearing leg 20 can accordingly move about the third pivot axis 34 during its pivotal movement.

側壁162還具有與第一開口166相對的第二開口168。由於第二剪切腿22可沿第四樞軸線38樞轉，因此第二剪切腿22可相應地貫穿該第二開口。 The sidewall 162 also has a second opening 168 opposite the first opening 166. Since the second shearing leg 22 is pivotable along the fourth pivot axis 38, the second shearing leg 22 can extend through the second opening accordingly.

在一個示例性實施例中，第一開口166和第二開口168是彼此連接的。 In an exemplary embodiment, the first opening 166 and the second opening 168 are connected to each other.

特別地，第一剪切腿22的第二區域56和第三區域58完全位於覆蓋裝置124的外側。第一區域54至少部分地定位在覆蓋裝置124的殼體164內。 In particular, the second region 56 and the third of the first shearing leg 22 The region 58 is completely outside the cover device 124. The first region 54 is at least partially positioned within the housing 164 of the cover device 124.

因此，第二剪切腿22的第二區域64和第三區域66完全位於覆蓋裝置124的外側。第二剪切腿22的第一區域62的至少一部分是位於殼體164內。 Therefore, the second region 64 and the third region 66 of the second shearing leg 22 are completely outside the covering device 124. At least a portion of the first region 62 of the second shearing leg 22 is located within the housing 164.

覆蓋裝置124在側壁162上也具有第三開口170，該第三開口是用於接觸操作元件86的進入開口。使用者可以經由第三開口170直接或間接地接近旋轉元件74，以施加對應於施加力130或142的力。 The cover device 124 also has a third opening 170 on the side wall 162 that is an access opening for contacting the operating element 86. The user can access the rotating element 74 directly or indirectly via the third opening 170 to apply a force corresponding to the applied force 130 or 142.

在所示的示例性實施例中，操作元件86穿過第三開口170，使得可以簡單的從覆蓋裝置124或殼體164外部接近旋轉元件74。 In the exemplary embodiment shown, the operating element 86 passes through the third opening 170 such that the rotating element 74 can be simply accessed from the outside of the cover 124 or the housing 164.

操作者然後可以以克服摩擦接合力的方式使旋轉元件74旋轉，特別是使用握持住保持裝置12的手的拇指為之。 The operator can then rotate the rotating element 74 in a manner that overcomes the frictional engagement force, particularly using the thumb of the hand holding the retaining device 12.

第三開口170包括一限制壁172。止擋122形成在限制壁172上。第一旋轉位置126藉由使操作元件86抵靠限制壁172來界定。 The third opening 170 includes a restriction wall 172. A stop 122 is formed on the restriction wall 172. The first rotational position 126 is defined by abutting the operating element 86 against the restraining wall 172.

為了限制最大開口寬度，第二手柄16的止擋174(圖9)形成在覆蓋裝置124上，特別是在殼體164的內部。 To limit the maximum opening width, a stop 174 (Fig. 9) of the second handle 16 is formed on the cover device 124, particularly inside the housing 164.

當覆蓋裝置124固定地連接到第一手柄14時，第二手柄16遠離第一手柄14的進一步樞轉可以通過使第二手柄16抵靠接觸該止動174而被阻擋。 When the cover device 124 is fixedly coupled to the first handle 14, further pivoting of the second handle 16 away from the first handle 14 can be blocked by abutting the second handle 16 against the stop 174.

為此目的，第二手柄16相應地包括有一反向止擋176，其中，覆蓋裝置124上的止擋174(因此間接地位於第一手柄14上)和反向止擋176彼此匹配。 For this purpose, the second handle 16 accordingly includes a reverse Stop 176, wherein stop 174 on cover device 124 (and thus indirectly on first handle 14) and reverse stop 176 match each other.

通過借助於止擋174和反向止擋176的打開限制，可防止剪切頭18被打開得太大。這種打開限制是必要的，以便確保切割刀片68具有足夠的重疊，從而防止輕切(nicking)。確保在切割刀片68和支撐件60之間存在足夠的偏壓。 By virtue of the opening restriction of the stop 174 and the reverse stop 176, the cutting head 18 can be prevented from being opened too much. This opening restriction is necessary to ensure that the cutting blades 68 have sufficient overlap to prevent nicking. Ensure that there is sufficient bias between the cutting blade 68 and the support member 60.

在一具體實施例中，止擋174與反向止擋176的形成是使得在第二樞軸線30處的最大打開角度為42°。 In one embodiment, the stop 174 and the reverse stop 176 are formed such that the maximum opening angle at the second pivot axis 30 is 42°.

保持裝置12在下端104處的手柄開口為113mm。 The handle opening of the retaining device 12 at the lower end 104 is 113 mm.

槓桿傳動比為1：4.5。 The lever ratio is 1:4.5.

剪刀10的功能如下：執行切割運動時，鎖定被抵消。因此，鎖定裝置72不是處於其第一位置128。 The function of the scissors 10 is as follows: when the cutting motion is performed, the lock is cancelled. Therefore, the locking device 72 is not in its first position 128.

藉由使第二手柄16沿第二樞軸線30朝向第一手柄14樞轉來執行切割運動。剪切頭18因此被關閉，而可以進行切割。 The cutting motion is performed by pivoting the second handle 16 along the second pivot axis 30 toward the first handle 14. The cutting head 18 is thus closed and the cutting can be performed.

在第二手柄16相對於第一手柄14的特定位置中，旋轉元件74的旋轉可以通過配對元件76來實現；鎖定裝置72處於其第二位置134。旋轉元件74的這種旋轉使得在旋轉元件74和配對元件76之間不能建立確實嚙合，也就是說不能提供鎖定。 In a particular position of the second handle 16 relative to the first handle 14, rotation of the rotating element 74 can be achieved by the mating element 76; the locking device 72 is in its second position 134. This rotation of the rotating element 74 makes it impossible to establish a positive engagement between the rotating element 74 and the mating element 76, that is to say that no locking can be provided.

一旦切割過程完成，剪切頭18的關閉位置即被鎖定。為此目地，舉例言之，藉由使用者明顯的施加力142使得旋轉元件74從鎖定裝置72的第二位置134開始進入第三旋轉位置140而產生第三位置138。通過第二手柄16相對於第一手柄14的適當定位，藉由將旋轉元件74旋轉入第一旋轉位置126，可實現鎖合，所述鎖合是藉由使得突起90進入凹部106，而銷114進入凹部92中來實現。在此，進入第一旋轉位置126的運動尤其是通過使用者的明顯干預來實現的。在隨後獲得的鎖定裝置72的第一位置128中，剪切頭18的關閉位置被鎖定，進而被固定。 Once the cutting process is completed, the closed position of the cutting head 18 is locked. For this purpose, for example, by the user's obvious application The force 142 causes the rotating element 74 to enter the third rotational position 140 from the second position 134 of the locking device 72 to produce the third position 138. By proper positioning of the second handle 16 relative to the first handle 14, locking can be achieved by rotating the rotating element 74 into the first rotational position 126, which is achieved by having the projection 90 enter the recess 106. 114 is implemented by entering the recess 92. Here, the movement into the first rotational position 126 is achieved in particular by a significant intervention by the user. In the first position 128 of the locking device 72 that is subsequently obtained, the closed position of the cutting head 18 is locked and thus fixed.

剪刀10包括覆蓋裝置124，其特別地形成殼體164。鎖定裝置72是以受保護的方式配置在殼體164內。因此本發明所提供的鎖定裝置，其與例如在WO 2011/089028A1案所揭露的簡單垂片相比，是以較複雜的方式構建。另外，使用者的手也由覆蓋裝置124來保護，因為消除了使用者的手在鎖定裝置處被擠壓的風險。 The scissors 10 include a cover device 124 that in particular forms a housing 164. The locking device 72 is disposed within the housing 164 in a protected manner. The locking device provided by the present invention is thus constructed in a more complicated manner than the simple tabs disclosed, for example, in WO 2011/089028 A1. In addition, the user's hand is also protected by the cover device 124 because the risk of the user's hand being squeezed at the locking device is eliminated.

剪刀10可以以精簡的方式構造，其中鎖定裝置72的相應機構可以以受保護且節省空間的方式定位配置。 The scissors 10 can be constructed in a compact manner, with the corresponding mechanism of the locking device 72 being positionable in a protected and space-saving manner.

本發明提供了高水準的使用者友好性(容易使用)，特別是可單手操作的可能性。 The present invention provides a high level of user friendliness (ease of use), especially the possibility of one-handed operation.

覆蓋裝置124也可用以藉間隙154的寬度156來界定最小間距。 Covering device 124 can also be used to define the minimum spacing by the width 156 of gap 154.

覆蓋裝置124也可用於界定止擋122，以限制剪切頭18的最大開口寬度。 Covering device 124 can also be used to define stop 122 to limit the maximum opening width of shear head 18.

此外，鎖定裝置72的止擋122也可以藉由覆蓋裝置124來預先界定。 Furthermore, the stop 122 of the locking device 72 can also be predefined by the covering device 124.

由於覆蓋裝置124的關係，特別是當其是以殼體164構形時，剪刀10的其他元件，特別是樞軸承28,32也可以以受保護的方式配置，且樞軸承36同樣也可以，至少是在關閉位置時。 Due to the relationship of the covering means 124, in particular when it is configured by the housing 164, the other elements of the scissors 10, in particular the pivot bearings 28, 32, can also be arranged in a protected manner, and the pivot bearing 36 can likewise be used, At least when it is in the off position.

剪刀10可以少量的部件而以精簡緊湊的方式構成。 The scissors 10 can be constructed in a compact and compact manner with a small number of components.

彈簧裝置70傾向於使第一手柄14和第二手柄16沿第二樞軸線30樞轉而遠離彼此，直到反向止擋176接觸止擋174為止。 The spring device 70 tends to pivot the first handle 14 and the second handle 16 along the second pivot axis 30 away from each other until the reverse stop 176 contacts the stop 174.

由於鎖定裝置72的關係，第一位置128通過強制接合，可抗衡彈簧裝置70的力的作用而被鎖定。 Due to the relationship of the locking device 72, the first position 128 can be locked by the force of the spring device 70 by forced engagement.

在本文中，剪刀10被描述為具有固定到第一手柄14的覆蓋裝置124。 Herein, the scissors 10 are depicted as having a cover device 124 that is secured to the first handle 14.

原則上，覆蓋裝置也可以固定到第二手柄16，並且第一手柄14可相對於覆蓋裝置移動。 In principle, the covering device can also be fixed to the second handle 16, and the first handle 14 can be moved relative to the covering device.

特別地，鎖定裝置72的旋轉元件然後被配置在第二手柄16上。 In particular, the rotating element of the locking device 72 is then arranged on the second handle 16.

根據本發明的剪刀的另一示例性實施例在圖17中部分地示出並且由標號180表示，原則上與剪刀10以相同方式形成。 Another exemplary embodiment of a scissors according to the present invention is partially shown in Figure 17 and is indicated by reference numeral 180, in principle formed in the same manner as the scissors 10.

在剪刀180的情形中，設置有用於旋轉元件74的配對元件182，該配對元件設置在相應的第二剪切腿22'上。(在剪刀10的情況下，配對元件76是配置在第二手柄16上)。 In the case of the scissors 180, a mating element 182 for the rotating element 74 is provided, which is provided on the respective second shearing leg 22'. (In the case of the scissors 10, the mating element 76 is disposed on the second handle 16).

配對元件182特別地包括可界定凹部186的銷 184。 The mating component 182 specifically includes a pin that can define the recess 186 184.

如同剪刀10的情況一般，銷184可***到旋轉元件74中的凹部92內。 As is the case with the scissors 10, the pin 184 can be inserted into the recess 92 in the rotating element 74.

旋轉元件74的突起90可***配對元件182中的凹部186內。 The protrusion 90 of the rotating element 74 can be inserted into the recess 186 in the mating element 182.

通過旋轉元件74和配對元件182(因此第一手柄14和第二剪切腿22')之間的確實鎖定連接，可獲得一確實鎖定連接，而得以鎖定剪切頭18的關閉位置。 By the positive locking connection between the rotating element 74 and the mating element 182 (and thus the first handle 14 and the second shearing leg 22'), a positive locking connection can be obtained to lock the closed position of the cutting head 18.

由於第二剪切腿22'與第二手柄16的相應聯接，因此也實現了第一手柄14和第二手柄16之間的相對鎖定。 Due to the corresponding coupling of the second shearing leg 22' with the second handle 16, a relative lock between the first handle 14 and the second handle 16 is also achieved.

除另外說明之外，剪刀180的功能是和上文述及的剪刀10所描述一樣。 The function of the scissors 180 is the same as described for the scissors 10 described above, unless otherwise stated.
