Abstract
Description
本發明涉及手動操作鋸子的握持技術。 The present invention relates to a gripping technique for manually operating a saw.
臺灣公告第43428號專利案揭露一種鋸子，將一鋸片局部固定在一握把上。用單手或雙手握緊握把，操作其餘的鋸片來執行鋸切作業。 Taiwan Patent No. 43428 discloses a saw for partially fixing a saw blade to a grip. Hold the grip with one hand or both hands and operate the remaining saw blades to perform the sawing operation.
法國第2,624,780號專利案披露另一款鋸子，以握把銜接一弓形部組成新的鋸架，鋸架大致呈U形而可聯結固定鋸片二端。在使用期間，一手握住握把，另隻手握住弓形部，操作鋸片執行鋸切作業。 Patent No. 2,624,780 discloses another saw in which the grip engages an arcuate portion to form a new saw frame which is generally U-shaped and can be coupled to the ends of the fixed saw blade. During use, hold the grip with one hand, hold the bow with the other hand, and operate the saw blade to perform the sawing operation.
雖然，雙手握住鋸架的使用模式，比單手操作更平穩。但是，弓形部大都是金屬材質製成，堅硬結構易傷及手部，有加以改良之必要。 Although the use mode of the saw holder with both hands is smoother than one-handed operation. However, the bows are mostly made of metal material, and the hard structure is easy to hurt and the hand is necessary for improvement.
本發明主要目的在於：採用人體工學的構造，既能保護鋸架，又能舒適地握住鋸架，避免人體受到傷害。 The main purpose of the invention is to adopt an ergonomic structure, which can protect the saw frame and comfortably hold the saw frame to avoid injury to the human body.
緣於上述目的之達成，本發明的鋸子包括一鋸片、一鋸架與一中空的握套。所述的鋸架有一弓形部與一握把，握把連接弓形部，允許鋸片安裝在鋸架而可卸除。握套有二開口，以 握套圍住弓形部靠近自由端處，有利於手部握緊握套，操作鋸架帶動鋸片執行鋸切作業。 For the above purposes, the saw of the present invention includes a saw blade, a saw frame and a hollow grip. The saw frame has an arcuate portion and a grip, and the grip connects the arcuate portion, allowing the saw blade to be mounted on the saw frame for removal. The grip has two openings to The grip sleeve surrounds the arcuate portion near the free end, which facilitates the grip of the grip by the hand, and operates the saw blade to drive the saw blade to perform the sawing operation.
採用套接模式，握套可套住弓形部。弓形部剖面大致呈I形設計，以橫向剖面支撐握套內壁且形成大致呈多邊形的內部空間。弓形部的縱向剖面為界，將握套的內部隔成二空間。 In the socket mode, the grip can cover the bow. The arcuate section has a generally I-shaped cross-section that supports the inner wall of the grip in a lateral section and defines a generally polygonal interior space. The longitudinal section of the arcuate portion is bounded, and the interior of the grip is divided into two spaces.
當然，握套可加設二凸部。每個凸部形成於握套面對弓形部的縱向剖面處，縮減空間的容積。 Of course, the grip can be provided with two convex portions. Each of the projections is formed at a longitudinal section of the grip facing the arcuate portion to reduce the volume of the space.
採用射出成型模式，讓握套包住弓形部外表。倘若弓形部的剖面大致呈I形設計，橫向剖面支撐握套內壁。握套面對弓形部的縱向剖面處形成二凸部，每個凸部填滿弓形部以縱向剖面配合橫向剖面構成的空間中。 The injection molding mode is used to enclose the outer shape of the bow. If the cross section of the bow is substantially I-shaped, the transverse section supports the inner wall of the grip. Two protrusions are formed at a longitudinal section of the grip sleeve facing the arcuate portion, and each of the protrusions fills the arcuate portion to fit the space formed by the transverse section in a longitudinal section.
因此，握套被握緊時，手部存在虛實相間的握感，更趨近於人體工學舒適性的設計。 Therefore, when the grip is gripped, the hand has a virtual and real grip, and is closer to the design of ergonomic comfort.
另外，握套底端靠近弓形部自由端，握套鄰近頂端處形成一有利於使用者手部放置的人體工學置放區，並在握套外表佈置一些止滑結構，便利鋸架帶動鋸片執行鋸切作業。 In addition, the bottom end of the grip sleeve is close to the free end of the arcuate portion, and an ergonomic placement area for facilitating the placement of the user's hand is formed adjacent to the top end of the grip sleeve, and some anti-slip structure is arranged on the outer surface of the grip sleeve to facilitate the saw blade to drive the saw blade Perform a sawing operation.

請參閱第1、2圖，闡明鋸子10第一實施例的具體構造，是由一鋸片12、一鋸架20以及一握套40組成。其中，鋸片12大致呈矩形，界定二長邊之一為齒狀鋸切邊，並在鋸片12靠近二端處分別貫穿一孔14。 Referring to Figures 1 and 2, the specific configuration of the first embodiment of the saw 10 is illustrated by a saw blade 12, a saw frame 20 and a grip 40. Wherein, the saw blade 12 is substantially rectangular, and one of the two long sides is defined as a serrated sawing edge, and a hole 14 is respectively penetrated through the saw blade 12 near the two ends.
圖中，所述的鋸架20大致呈弓形且設計為一體。鋸架20包括一弓形部22與一握把26。在弓形部22後段延伸一防護段24，防護段24銜接握把26，保護一使用者握住握把26的手部。在弓形部22的自由端還有一凸柱28。 In the figures, the saw frame 20 is generally arcuate and designed as one piece. The saw frame 20 includes an arcuate portion 22 and a grip 26. A guard segment 24 extends from the rear of the arcuate portion 22, and the guard segment 24 engages the grip 26 to protect a user's grip on the grip 26. There is also a stud 28 at the free end of the arcuate portion 22.
在某些實施例，鋸架20分成二部份：握把26與弓形部22設計成為一體，省去或刪除防護段。 In some embodiments, the saw frame 20 is divided into two portions: the grip 26 is integrally formed with the arcuate portion 22, eliminating or eliminating the guard segment.
一拉伸調整裝置位於握把26下方，其由一槓桿30與一緊固件38組成。該槓桿30樞接於握把26和防護段24鄰接處，界定樞接處為支點32，支點32一邊視為抗力臂34，另邊充當施力臂36，在施力臂36靠近自由端處設置緊固件38。因此，槓桿30繞著支點32在一關閉位置與一開啟位置之間運動。 A tension adjustment device is located below the grip 26 and is comprised of a lever 30 and a fastener 38. The lever 30 is pivotally connected to the grip 26 and the guard segment 24, and the pivot point is defined as a fulcrum 32. The fulcrum 32 is regarded as the resistance arm 34 on one side and acts as the urging arm 36 on the other side, near the free end of the urging arm 36. A fastener 38 is provided. Thus, the lever 30 moves about a fulcrum 32 between a closed position and an open position.
在本實施例，抗力臂34比施力臂36短。在某些實施例，抗力臂34與施力臂36的長度相等。當然，抗力臂34比施力臂36長，亦屬於本發明允許實施的範圍內。 In the present embodiment, the resistance arm 34 is shorter than the force applying arm 36. In some embodiments, the resistance arm 34 is equal in length to the force arm 36. Of course, the resistance arm 34 is longer than the force application arm 36 and is also within the scope of the present invention.
在開啟位置時，緊固件38與握把26保持鬆脫或卸除狀態，槓桿30擺動且縮短抗力臂34至弓形部22自由端的距離。以 鋸片12左邊的孔14套住弓形部22的凸柱28，鋸片12右邊的孔14被一螺鎖單元16聯結在抗力臂34上。 In the open position, the fastener 38 and the grip 26 remain loose or disengaged, and the lever 30 swings and shortens the distance of the resist arm 34 to the free end of the arcuate portion 22. Take The hole 14 on the left side of the saw blade 12 encloses the boss 28 of the arcuate portion 22, and the hole 14 on the right side of the saw blade 12 is coupled to the resistance arm 34 by a screw lock unit 16.
在關閉位置時，施力臂36鄰近握把26底端，用緊固件38結合握把26，阻止槓桿30相對鋸架20旋轉，相對增加抗力臂34到弓形部22自由端的距離。 In the closed position, the force applying arm 36 is adjacent the bottom end of the grip 26, and the grip 26 is coupled with the fastener 38 to prevent the lever 30 from rotating relative to the saw frame 20, thereby increasing the distance of the resist arm 34 to the free end of the arcuate portion 22.
此刻，抗力臂34與弓形部22自由端的距離差異，除了將鋸片12二端固定在鋸架20以外，弓形部22產生形變而擁有彈力，對鋸片12產生拉伸作用，支撐鋸片12形成張力。在鋸切邊朝向第2圖下方的情況下，有利於鋸片12對一工件(如木塊等)進行鋸切作業。 At this moment, the distance between the resistance arm 34 and the free end of the arcuate portion 22 is different. In addition to fixing the two ends of the saw blade 12 to the saw frame 20, the arcuate portion 22 is deformed to have an elastic force, and the saw blade 12 is stretched to support the saw blade 12 Form tension. In the case where the sawing edge is toward the lower side of FIG. 2, it is advantageous for the saw blade 12 to perform a sawing operation on a workpiece such as a wooden block or the like.
如第4圖所示，弓形部22剖面大致呈I形設計，用以承載變形的作用力。 As shown in Fig. 4, the arcuate portion 22 is generally I-shaped in cross section to support the deforming force.
在第1~4圖中，握套40設計為一體。握套40有二開口42，每個開口42通往握套40中空的內部空間。在本實施例，該握套40是可伸縮的，套在弓形部22鄰近自由端處。換句話說，握套40圍住局部的弓形部22，以致握套40的內壁43被弓形部22的橫向剖面23支撐，形成大致呈矩形的內部空間。 In the first to fourth figures, the grip 40 is designed as one piece. The grip 40 has two openings 42, each opening 42 leading to a hollow interior of the grip 40. In the present embodiment, the grip 40 is telescopic and fits over the arcuate portion 22 adjacent the free end. In other words, the grip 40 encloses the partial arcuate portion 22 such that the inner wall 43 of the grip sleeve 40 is supported by the transverse section 23 of the arcuate portion 22 to form a generally rectangular interior space.
以弓形部22的縱向剖面21為界，將握套40的內部隔成二空間45。每個空間45在弓形部22的縱向剖面21側邊，以致握套40受力往空間45方向延伸，不同於弓形部22以橫向剖面23支撐握套40的構造，能夠讓使用者獲得虛實相間的握感，致生更趨近於人體工學舒適性的設計。 The interior of the grip 40 is divided into two spaces 45 by the longitudinal section 21 of the arcuate portion 22. Each of the spaces 45 is on the side of the longitudinal section 21 of the arcuate portion 22 such that the grip sleeve 40 is forced to extend in the direction of the space 45. Unlike the configuration in which the arcuate portion 22 supports the grip 40 in a transverse section 23, the user can obtain a virtual and real phase. The grip feels a life that is closer to the design of ergonomic comfort.
所述的握套40外觀輪廓大致呈矩形，界定二短邊為外側44與內側46，內側46的曲率大於外側44的曲率，或內側46半徑比外側44半徑小。圖中，握套40底端靠近弓形部22自由端，握套40的外側44鄰近頂端處形成一人體工學置放區41，有利於使用者的拇指放置。 The grip 40 has a generally rectangular outline, defining two short sides as the outer side 44 and the inner side 46, the inner side 46 having a curvature greater than the outer side 44, or the inner side 46 having a smaller radius than the outer side 44. In the figure, the bottom end of the grip sleeve 40 is adjacent to the free end of the arcuate portion 22. The outer side 44 of the grip sleeve 40 forms an ergonomic placement area 41 adjacent the top end to facilitate the user's thumb placement.
另外，握套40的外側44有一些止滑結構48，每個止滑結構48是條紋，可沿弓形部22的橫向剖面23形成於握套40的外側44，避免使用者的手部滑脫。在某些實施例，每個止滑結構48可以是突粒，佈置在握套40的外表。 In addition, the outer side 44 of the grip 40 has a plurality of anti-slip structures 48, each of which is a stripe formed on the outer side 44 of the grip 40 along the transverse section 23 of the arcuate portion 22 to prevent the user's hand from slipping off . In some embodiments, each anti-slip structure 48 can be a tab that is disposed on the exterior of the grip 40.
第5圖是鋸子的第二實施例，與第一實施例的差異處在於：握套40有二凸部47。每個凸部47形成於握套40面對弓形部22的縱向剖面21處，配合橫向剖面23形成空間45的容積，比第一實施例的空間容積還小。 Fig. 5 is a second embodiment of the saw, which differs from the first embodiment in that the grip 40 has two projections 47. Each of the projections 47 is formed at a longitudinal section 21 of the grip 40 facing the arcuate portion 22, and the volume of the space 45 is formed in cooperation with the transverse section 23, which is smaller than the volume of the space of the first embodiment.
第6圖是鋸子的第三實施例，不同於第二實施例之處是：握套40與弓形部22之間沒有空間45，縱向、橫向剖面21、23圍成的空間被握套40的凸部47填滿。因為握套40的凸部47比弓形部22的橫向剖面23柔軟，所以包覆弓形部22的握套40被使用者握緊時，仍舊存在虛實相間的握感。 Figure 6 is a third embodiment of the saw, which differs from the second embodiment in that there is no space 45 between the grip 40 and the arcuate portion 22, and the space enclosed by the longitudinal and transverse sections 21, 23 is gripped by the sleeve 40. The convex portion 47 is filled. Since the convex portion 47 of the grip 40 is softer than the transverse cross-section 23 of the arcuate portion 22, the grip 40 of the covering arch 22 is still gripped by the user when it is gripped by the user.
