Description
本發明係關於一種農藝、樹木培植、或園藝及其相關的工具,尤指一種用於修枝剪的多段調節裝置,以將該裝置鎖定或定位於開啟的角度。 The present invention relates to agronomic, tree planting, or horticultural and related tools, and more particularly to a multi-stage adjustment device for pruning shears to lock or position the device at an open angle.
當使用手持式修枝剪時,依使用者手部大小以及欲修剪之物體的大小而定,修枝剪張開的最大角度將成為使用者疲勞程度以及使用便利性的因素。有時對於手較小的使用者而言,使用張開角度較小的修枝剪可能是有幫助的,而對於手較大的使用者而言卻可能希望使用張開角度較大的修枝剪,而對於要修剪較大尺寸的物品時,具有較大的張開角度則較為有利。 When using a hand-held pruning shear, depending on the size of the user's hand and the size of the object to be trimmed, the maximum angle at which the pruning shears are opened will be a factor of user fatigue and ease of use. Sometimes it may be helpful for a user with a small hand to use a pruning shear with a small opening angle, but for a user with a larger hand, it may be desirable to use a pruning with a larger opening angle. Shearing, and it is advantageous to have a larger opening angle when it is necessary to trim a larger size item.
因此,能期望能有修枝剪具可調整開啟角度之功能。 Therefore, it can be expected that the pruning shear can be adjusted to the opening angle.
再者,當修枝剪未使用時,能將修枝剪鎖定在閉合位置下亦較為有利,藉此可避免對刀片造成損傷、或可降低對使用者造成傷害的機率。 Furthermore, it is also advantageous to be able to lock the pruning shears in the closed position when the pruning shears are not in use, thereby avoiding damage to the blades or reducing the risk of injury to the user.
依據所揭露內容,係提供一種鎖定機構,其可鎖定修枝剪,亦可調整修枝剪在使用時可開啟的最大角度。 In accordance with the disclosure, a locking mechanism is provided that locks the pruning shears and also adjusts the maximum angle at which the pruning shears can be opened during use.

如圖1至圖3所示,為修枝剪在全閉合、部分開啟、及全開啟位置下的圖式,多段鎖使得修枝剪可鎖定在如圖1所示之閉合位置、或如圖2及圖3所示在不同的開啟角度。修枝剪10包含有一左手柄12及一右手柄14、其上分別設有一切割元件16、18以構成夾爪,並藉由操作手柄12、14及樞轉一軸20以使該夾爪可開啟或閉合。該樞轉機構未示於圖中。一彈性元件22(多數圖中均省略之)兩端分別套設於一安裝片23、25上,以提供偏壓,則在手柄不受使用者或鎖定裝置之外力的情形下,偏壓仍能迫使夾爪朝開啟位置張開。一滑動開關24(或為鎖定控制鈕)使得修枝剪可鎖定閉合如圖1所示、或使夾爪可調整為不同角度的最大開啟狀態,在本實施例中,係提供兩種最大開啟位置,部分開啟量26如圖2所示,或全開啟量28如圖3所示,其餘實施例亦可依照需求而提供超過兩種最大角度的選擇,已適用於更多種開啟控制的調整。 As shown in Fig. 1 to Fig. 3, the figure of the pruning shear in the fully closed, partially opened, and fully open positions, the multi-segment lock enables the pruning shear to be locked in the closed position as shown in Fig. 1, or as shown in Fig. 2 and Figure 3 show different opening angles. The pruning shears 10 includes a left handle 12 and a right handle 14, respectively provided with cutting elements 16, 18 to form the jaws, and the jaws can be opened by operating the handles 12, 14 and pivoting a shaft 20. Or closed. This pivoting mechanism is not shown in the figures. A resilient member 22 (not shown in most of the figures) is sleeved on a mounting tab 23, 25 to provide a bias, and the bias is still applied to the handle without external force from the user or the locking device. Can force the jaws to open toward the open position. A slide switch 24 (or a lock control button) allows the pruning shear to be locked and closed as shown in Figure 1, or the jaws can be adjusted to a maximum open state at different angles. In this embodiment, two maximum openings are provided. The position, the partial opening amount 26 is as shown in FIG. 2, or the full opening amount 28 is as shown in FIG. 3, and the other embodiments can also provide more than two maximum angle selections according to requirements, which have been applied to more kinds of opening control adjustments. .
如圖4及圖5所示,分別為朝全閉合位置的鎖定控制動作圖(圖4)、及朝全開啟位置的鎖定控制動作圖(圖5)。滑動開關24可由開啟位置沿 箭頭30方向朝向切割元件18滑動,或沿箭頭32方向朝遠離切割元件18滑動。當沿箭頭30方向完全移動後,修枝剪係由如圖4所示之全開啟狀態變化為鎖定狀態;當沿箭頭32方向部分或完全移動後,修枝剪係由如圖5所示之全鎖定狀態變化為部分開啟或全開啟狀態。 As shown in FIGS. 4 and 5, the lock control operation diagram (FIG. 4) toward the fully closed position and the lock control operation diagram (FIG. 5) toward the full open position are shown. Slide switch 24 can be opened by the position The direction of the arrow 30 slides towards the cutting element 18 or slides away from the cutting element 18 in the direction of arrow 32. When fully moved in the direction of the arrow 30, the pruning shears are changed from the fully open state shown in FIG. 4 to the locked state; when partially or completely moved in the direction of the arrow 32, the pruning shears are as shown in FIG. The fully locked state changes to a partially open or fully open state.
圖6為一部份元件分解圖,其係移開滑動開關24,顯示設置於左手柄12之錨定組件34,該錨定組件34具有一第一錨定點36、一第二錨定點38、及一第三錨定點40,所述錨定點36、38、40呈半圓形凹陷成形於錨定組件34之開口42的任一側。如圖7所示,滑動開關24包含有相對應的定位凸部44(滑動開關24的兩側各有一個定位凸部44),其與錨定點36、38、40交互作用。一狹槽45設於滑動開關24上以使其可滑動接合於該開口42中,同時使定位凸部44與錨定點交互作用,該狹槽45、及該滑動開關24設有相對於該狹槽45上方及下方較寬的結構,使得該滑動開關能在滑動於狹槽中時保持於其中。 Figure 6 is an exploded view of a portion of the component, which is shown with the slide switch 24 removed, showing the anchor assembly 34 disposed on the left handle 12, the anchor assembly 34 having a first anchor point 36, a second anchor point 38, And a third anchor point 40, the anchor points 36, 38, 40 being formed in a semi-circular depression on either side of the opening 42 of the anchor assembly 34. As shown in FIG. 7, the slide switch 24 includes corresponding positioning projections 44 (one of the positioning projections 44 on each side of the slide switch 24) that interacts with the anchor points 36, 38, 40. A slot 45 is provided on the slide switch 24 to slidably engage the opening 42 while the positioning protrusion 44 interacts with the anchor point, the slot 45, and the slide switch 24 are provided with respect to the slot The wider structure above and below the slot 45 allows the slide switch to remain therein while sliding in the slot.
請進一步參閱圖8所示,為部分元件分解圖,所示為滑動開關與開口中的調整構件間的互動關係,修枝剪之切割元件18包含有一第一控制點48及一第二控制點50,所述控制點48、50設於切割元件18的下彎曲部,滑動開關24設有一嵌合凸部52已與所述控制點48、50交互作用。 Please refer to FIG. 8 for further partial component exploded view showing the interaction between the slide switch and the adjustment member in the opening. The cutting element 18 of the pruning shear includes a first control point 48 and a second control point. 50, the control points 48, 50 are provided in the lower bend of the cutting element 18, and the slide switch 24 is provided with a fitting projection 52 that has interacted with the control points 48, 50.
操作時,當滑動開關24沿箭頭30之方向移動至最遠距離時,修枝剪為全閉合狀態,此時嵌合凸部52緊靠於切割元件18之第一控制點48上,則嵌合凸部52之肩部與第一控制點48之內表面56相抵靠,以有效的將修枝剪鎖定於閉合位置,此時滑動開關24之定位凸部44嵌合於第三錨定點40中,以將滑動開關加以定位,則修枝剪將如圖1所示為鎖定在全閉合位置。 In operation, when the slide switch 24 is moved to the furthest distance in the direction of the arrow 30, the pruning shear is in a fully closed state, at which time the fitting projection 52 abuts against the first control point 48 of the cutting element 18, and is embedded The shoulder of the convex portion 52 abuts against the inner surface 56 of the first control point 48 to effectively lock the pruning shear to the closed position, at which time the positioning convex portion 44 of the slide switch 24 is fitted to the third anchor point 40. In order to position the slide switch, the pruning shear will be locked in the fully closed position as shown in FIG.
為了調整修枝剪,使用者將略為同時施壓於左、右手柄12、14,以釋放嵌合凸部52抵靠於內表面56的壓力,則可將滑動開關24沿箭頭32方向滑動,使得定位凸部44脫離第三錨定點40並移動至第二錨定點38,嵌合凸部52因 此朝遠離切割元件的方向移動,若使用者此時停止滑動該滑動開關24,則定位凸部44與該第二錨定點38相嵌合,並放開手柄後,修枝剪將可開啟至當嵌合凸部52與第二控制點50相抵靠之處。嵌合凸部52之肩部將與第二控制點50之內表面58相抵靠以阻止修枝剪開啟至更大的角度,因此,修枝剪可如圖2所示在半開啟位置下作業,該狀態可被用來如在修剪較小尺寸之物品時。 In order to adjust the pruning shears, the user will slightly press the left and right handles 12, 14 simultaneously to release the pressure of the fitting projections 52 against the inner surface 56, so that the slide switch 24 can be slid in the direction of the arrow 32. The positioning convex portion 44 is disengaged from the third anchor point 40 and moved to the second anchor point 38, and the fitting convex portion 52 is caused by The movement moves away from the cutting element. If the user stops sliding the sliding switch 24 at this time, the positioning protrusion 44 is engaged with the second anchor point 38, and after the handle is released, the pruning shear can be opened to When the fitting convex portion 52 abuts against the second control point 50. The shoulder of the fitting projection 52 will abut against the inner surface 58 of the second control point 50 to prevent the pruning shear from opening to a greater angle, so that the pruning shear can be operated in the semi-open position as shown in FIG. This state can be used, for example, when trimming smaller sized items.
在將滑動開關24進一步朝箭頭32的方向移動(較佳係略為同時施壓於左、右手柄),定位凸部44脫離第二錨定點38並移動至與第一錨定點36相嵌合,在此位置下,滑動開關24之嵌合凸部52將不會再受限於任一控制點48、50,故當放開手柄時,修枝剪可開啟至如圖3所示之全開啟狀態,該狀態可被用來如在修剪較大尺寸之物品時。 When the slide switch 24 is further moved in the direction of the arrow 32 (preferably slightly simultaneously applied to the left and right handles), the positioning projection 44 is disengaged from the second anchor point 38 and moved to engage with the first anchor point 36. In this position, the fitting projection 52 of the slide switch 24 will no longer be limited to any of the control points 48, 50, so when the handle is released, the pruning shear can be opened to fully open as shown in FIG. State, which can be used, for example, when trimming larger sized items.
請參閱圖9所示,為滑動開關24由修枝剪取下後之底視圖,定位凸部44為一彈性體54之凸部,該彈性體54固定於該滑動開關24之一容室56中,當滑動開關24移動時,彈性體54可屈曲以略為將定位凸部44縮回,而使得滑動開關24得以移動,藉由彈性體的偏壓,定位凸部44延伸已與錨定點相嵌合,藉此操作,則滑動開關可被移動但當釋放外力時亦可定位在該位置上。 Referring to FIG. 9 , the bottom view of the slide switch 24 is removed from the pruning shear. The positioning protrusion 44 is a convex portion of the elastic body 54 . The elastic body 54 is fixed to a chamber 56 of the slide switch 24 . When the slide switch 24 is moved, the elastic body 54 can be flexed to slightly retract the positioning convex portion 44, so that the slide switch 24 is moved, and the positioning convex portion 44 extends to be anchored with the anchor point by the bias of the elastic body. By fitting, by this operation, the slide switch can be moved but can also be positioned at this position when an external force is released.
請參閱圖10及圖11所示之分解圖,說明滑動開關、錨定組件的更換與交互作用,一凹槽62成形於左手柄12以容置錨定組件34於其中,並藉由螺絲60加以固定,本實施例中以三顆螺絲加以固定之。相對應的螺絲孔61適當地成形於左手柄12中以容置所述螺絲,所示滑動開關24為彈性體54分離的狀態,所述彈性體54可為一彈片,彈性體54具有彎曲的翼部55,所述翼部55構成所述定位凸部44,以在操作時可選擇性地與錨定點36、38、40相嵌合,進而界定鎖定狀態。 Referring to the exploded view shown in FIG. 10 and FIG. 11, the replacement and interaction of the slide switch and the anchor assembly are illustrated. A recess 62 is formed in the left handle 12 to receive the anchor assembly 34 therein and is provided by the screw 60. It is fixed, and is fixed by three screws in this embodiment. Corresponding screw holes 61 are suitably formed in the left handle 12 to accommodate the screws. The slide switch 24 is shown in a state in which the elastic body 54 is separated. The elastic body 54 may be a spring piece, and the elastic body 54 has a curved shape. A wing portion 55, which defines the positioning projection 44, is selectively engageable with the anchor points 36, 38, 40 during operation to define a locked condition.
雖然所示實施例中描述了3種操作位置,鎖定閉合、部分開啟、及全開啟,但可提供更多的錨定點及控制點以使修枝剪可具有更多段的最大開 啟角度,當具有n個錨定點時,須具有n-1個控制點,藉此將修枝剪鎖定在n個位置下。開啟的最大角度可為等間隔設置,例如全閉合、1/4開啟、1/2開啟、3/4開啟、及全開啟;或可為不等間隔設置,例如全閉合、1/4開啟、3/4開啟、及全開啟。開啟的角度及定位的數量可依照使用者的需求或手掌尺寸來加以變化。 Although three operational positions are described in the illustrated embodiment, lock closed, partially open, and fully open, more anchor points and control points may be provided to allow the pruning shears to have more segments of maximum opening. The angle of rotation, when having n anchor points, must have n-1 control points, thereby locking the pruning shears at n positions. The maximum angle of opening can be equal interval setting, such as full closure, 1/4 open, 1/2 open, 3/4 open, and full open; or can be set at unequal intervals, such as fully closed, 1/4 open, 3/4 is on and fully on. The angle of opening and the number of positionings can be varied according to the needs of the user or the size of the palm.
由於可調整剪切時開口的最大角度,則無須重複進行全開啟及全閉合的循環,如此則有助於本裝置之現場使用的壽命和改進的人體工學。 Since the maximum angle of the opening during shearing can be adjusted, there is no need to repeat the full opening and full closing cycles, which contributes to the life of the device and improved ergonomics.
儘管已經示出和描述了本技術的較佳實施例,但是對於所屬技術領域中具有通常知識者來說,顯而易見的是,在不脫離更廣泛的方面的情況下可以進行許多改變和修改。因此,所附申請專利範圍旨在覆蓋落入本技術的真實精神和範圍內的所有這樣的改變和修改。 While a preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that many changes and modifications can be made without departing from the broader aspects. Accordingly, the scope of the appended claims is intended to cover all such modifications and
