(2) (2)200302194 邊進行皮帶拉緊作業時，由於止動爪在從齒輪部的峰部向 谷部的急劇地移動與抵接，故，發出很大的衝擊聲。 又，一旦拉緊皮帶，而將貨物進行繫緊固定時，在固 定著皮帶的卡車兩側上也作用有朝向卡車車箱的內側的很 大的作用力。因此，當將止動爪從棘輪機構脫離，皮帶捲 繞軸能向皮帶放鬆方向轉動時，作用於皮帶上的張力便一 下子釋放出來。隨之，因作用於固定皮帶的一端側的卡車 車箱的兩側壁上的力也一下子釋放出來，所以卡車車箱的 兩側壁會産生劇烈振動並發出破裂聲。 如此，以往的皮帶繫緊用具，在進行皮帶的拉緊及放 鬆作業時存在著向周圍發出很大噪音的問題。此問題在對 小型無人管理商店等進行淸晨及夜間進貨的卡車上尤爲明 因此，本發明是提供一種能夠防止在進行皮帶拉緊及 放鬆作業時産生噪音的皮帶繫緊用具。 【發明內容】 【發明的揭示】 本發明的皮帶繫緊用具是一種第1皮帶和第2皮帶分 別連結在其一端部和另一端部上，進行相對這些皮帶的張 涂之皮帶繫緊用具，其特 框架；設於前述主體框架的一端部並能捲繞及反繞前述第 1皮帶的皮帶捲繞機構；設於前述主體框架的另一端部並 能以少量長度反繞前述第2皮帶的皮帶放鬆機構，而前述 (3) 200302194 皮帶放鬆機構是具有：重疊並引導前述第2 、從前述第1軸向遠離方向延伸地形成於前 的長孔、移動自如及轉動自如地支承於前述 該長孔的軸線大致垂直的平面相接觸，並且 1軸引導的第2皮帶進行捲繞而引導至前述 軸、以及設於前述第2軸的一端部，並使該 轉動桿。 根據前述結構的話，能利用使第2軸轉 以少量長度緩慢地進行反繞。因而能抑制解 車側壁的振動並降低噪音。 又，本發明的皮帶繫緊用具的前述第2 至少與前述平面接觸部分的斷面爲多邊形狀 藉此，可確實地進行第2皮帶的反繞。 又’本發明的皮帶繫緊用具，是一種第 皮帶分別連結在其一端部和另一端部上，進 帶的張力的産生和解除的皮帶繫緊用具，其 •主體框架；設於前述主體框架的其中一端 反繞前述第1皮帶的皮帶捲繞機構；設於前 另一端部並能以少量長度反繞前述第2皮帶 構’前述皮帶放鬆機構是設有··重疊並引導 主體框架上轉動自姻趣Ifr 第1軸引導的第2皮帶反繞後引導到前述第 •，設於前述第2軸的一端部上並使該第2軸 ;以及用來限制前述第2軸轉動的鎖定裝置 皮帶的第1軸 述主體框架上 長孔上且在與 ’將從前述第 第1軸的第2 第2軸轉動的 動將第2皮帶 除張力時的卡 軸的特徵爲： 或凸輪形狀。 1皮帶和第2 行相對這些皮 特徵爲：設有 部並能捲繞及 述主體框架的 的皮帶放鬆機 前述第2皮帶 1軸的第2軸 轉動的轉動桿 。藉此，能利 -8 -

[Prior Art] Conventionally, belt fastenings for fixing cargoes loaded in truck boxes have been provided with a belt bridged between the side walls of the box and a ratchet belt fastening device for tightening and loosening the belt. The ratchet-type belt fastening device is composed of a belt winding shaft for winding the belt, a belt winding shaft that runs through the center portion and forms a ratchet of the gear portion, and can be used to snap the ratchet. The ratchet is a stop pawl that rotates in only one direction; and a handle that allows the belt winding shaft to rotate in the winding direction. In the aforementioned structure, when the cargo is fixed, one end of each of the two belts is fixed to the side wall of the truck, and the other end of each of the two belts is connected to the belt fastening device at a substantially central portion of the truck box. Then, use the handle to wind the belt around the axis and tighten the belt tightly to secure the cargo. In addition, when the cargo is unfastened, the belt pawl shaft can be freely rotated by retracting the stopper from the ratchet to the disengaged position. Thereby, the belt is loosened in the direction in which the belt is wound in the axial direction to be loosened by the tension of the belt, so as to release it. In this way, the belt tightening and loosening operation can be easily performed using conventional belt tightening tools. However, in In the aforementioned conventional structure, when the ratchet is turned while using the handle to rotate the -6-(2) (2) 200302194, the stopper claws move sharply from the peak portion to the valley portion of the gear portion and come into contact with each other when the belt is tightened. Therefore, it makes a great impact. When the belt is tightened and the cargo is fastened, a large force is applied to both sides of the truck to which the belt is fixed, toward the inner side of the truck box. Therefore, when the stopper is disengaged from the ratchet mechanism, and the belt winding shaft can be rotated in the belt loosening direction, the tension acting on the belt is released at once. As a result, the forces acting on the two side walls of the truck box at one end side of the fixed belt are released at once, so the two side walls of the truck box vibrate violently and make a cracking sound. As described above, the conventional belt tightening device has a problem of making a lot of noise to the surroundings when the belt is tightened and loosened. This problem is particularly noticeable in trucks that receive goods in the morning and at night at small unmanned stores. Therefore, the present invention is to provide a belt tightening device capable of preventing noise from being generated during belt tightening and loosening operations.

The receiving recess 2 5 d is a thickness even after the first belt 1 is wound on the winding shaft 7. The increase does not cause the first belt 1 to touch the first latch buckle 25. Therefore, when the first latch hasp 25 of this structure is given by the operator with his or her hand off, and only the spring force of the spring member 26 is given, as shown by the solid line in the figure, it is engaged with the ith one-way clutch 8 Together. On the other hand, when the operator lifts up the first latch hasp 5 and moves it to the position shown by a double-dot chain line in the figure, the engagement with the first one-way clutch 8 is released. In addition, the i-th latch clasp 2 does not engage the second one-way clutch 9 whether or not it is lifted. The side of the 'engaging portion 2 5 b protrudes outside the first latch hasp 2 5. The protruding end of the engaging portion 25b is moved from the member 27 as shown in FIG. 1. -^^^ Good piece 27 is a brother ^ If the ground shaft is supported on the belt winding shaft 7, the pair of handle support plates 22 are arranged side by side via the first one-way clutch 8. Thereby, the engaging portion 25b is supported in the rotation direction by the support plate 22 and the support plate member 27 in the rotation direction -13- (9) (9) 200302194, and can exert a strong rigid effect between the two members 22, 27, even if Even when the belt winding shaft 7 is rotated by the first one-way clutch 8 and the first belt 1 is wound, no bending is caused by the reaction force during winding. In addition, brake members 30 and 30 are provided at both ends of the belt winding shaft 7, respectively. The first one-way clutch 8-the brake member 3 0 is arranged between the frame plate 4 and the handle support plate 22, and the second one-way clutch 9-the brake member 30 is arranged on the second one-way clutch 9. And frame plate 4. As shown in Fig. 5, an outer peripheral surface of each brake member 30 is formed with a protruding portion 30a which is set at substantially the same height as the protruding portions 10b of the first and second one-way clutches 8 and 9. Each of the projecting portions 30a and 30a can be brought into contact with the engaging portion 2 5b and the engaging avoidance portion 25c of the first latch hasp 25 of FIG. 6, respectively, and the first latch can be raised by Buckle 25 to avoid abutment. Each of the protruding portions 30a and 30a is set to the end point of the winding operation of the handle 20, and the handle 20 is locked to prevent the operation of the belt release mechanism 6 to be described later. In addition, in the brake member 30, a locking recessed portion 30b is formed below the protruding portion 30a. A front end portion of a second latching buckle 31 is fitted in the locking recess 3 Ob, and the second latching buckle 31 is used to inhibit rotation of the brake member 30. As shown in FIG. 1, the second latch hasp 31 is movably provided on the frame plates 4 and 4 so that the front end portion advances and retreats in the direction of the belt winding shaft 7, and a spring 3 is bound in a compressed state. 2. The spring 3 2 pushes the second latch buckle 31 toward the belt winding shaft 7. On the front end side of the second latch hasp 31, as shown in FIG. 6, -14- (10) (10) 200302194 is formed at both ends in the width direction: it is engaged with the second one-way clutch 9 The engagement portion 3 1 a of the recessed portion 10 a and the engagement avoidance portion 31 b that avoids engagement with the recessed portion 10 a of the first one-way clutch 8. A receiving recess 3 1 c is formed between the engaging portion 31 a and the engaging avoiding portion 3 1 b. The receiving recess 3 1 c increases in thickness even when the first belt 1 is wound around the winding shaft 7. In this case, the first belt 1 will not be brought into contact with the second latch buckle 31. Therefore, as shown in FIG. 5, the second latch hasp 31 of this structure is also used when the elastic member of the spring member 32 is positioned on the belt winding shaft 7 side of the solid line in the figure. Engagement with the second one-way clutch 9; on the other hand, when retracting to the avoiding position of the two-dot chain line in the figure, engagement with the second one-way clutch 9 is released. In addition, the second latch hasp 31 is not engaged with the first one-way clutch 8 regardless of whether it is lifted or not. The second latch buckle 31 is moved backward by the handle 20. That is, the handle supporting plates 2 1 and 22 of the handle 20 have a curved shape that slightly protrudes from the base portion, and the base portion contacts the front end of the second latch hasp 31 to make the second latch has 31 to avoid. Backward direction. A handle locking portion 4a is formed at an end portion of the frame plate 4 in the longitudinal direction. When the handle locking portion 4a is in an open state in which the handle 20 is in the opened state after the second latch buckle 31 is turned back to the avoiding position, the first latch buckle 25 is fitted to prohibit the handle. 2 0 turns. In addition, the handle locking portion 4 a is set as shown in FIG. 6, and the joint portion is set to the price. When the handle 20 is opened by the handle locking portion 4 a, as shown by the double-dotted dotted line in FIG. 6, The first and second latches 2 5 and 31 and the first and second one-way clutches 8 and 9 are completely prevented from engaging with each other. -15- (11) (11) 200302194 causes the belt to be wound. The shaft 7 can rotate freely to the frame plate 4. As shown in FIG. 1, the winding mechanism 5 having the above structure is configured to open the main frame 3 by turning the handle 20 in the direction of opening to the main frame 3 while lifting the first latching buckle 25, and using the Turn it in the opposite direction (locking direction) to form a locked state. When the handle 20 is turned without lifting the first latch fastener 25, the protrusions 30a and the handle support plates 2 1 and 2 abutting against the brake member 30 are formed before each state is formed. 2. Therefore, by turning the handle 20 alternately in the closing direction and the opening direction between the two positions, the first belt can be wound on the belt winding shaft 7 as described later. The other end portion of the main body frame 3 provided at the one end portion of the belt winding mechanism 5 is provided with a belt release mechanism 6 for slowly rewinding the second belt 2.

In the " fat ~ heavy bearing plate 2 1 a. The long hole 4 1 a is set so that the long axis direction is perpendicular to the inclined surface 4 b. In the long holes 4 1 a, 4 1 a of the three opposite support plates 2 1, 4 1, a second shaft 45 capable of winding the second belt 2 guided by the first shaft 42 is inserted. (12) (12) 200302194 The cross section of the second shaft 45 at both ends is rounded, and the cross section of the part excluding the both ends is hexagonal. Therefore, the hexagonal cross-section of the second shaft 45 touches the upper end of the inclined surface 4b of the plane frame plate 4 substantially perpendicular to the axis of the long hole 4a. A rotation lever 47 for rotating the second shaft 45 is fixed to one end portion 'of the second shaft 45. As a result, as shown in FIG. 9, the belt slackening mechanism 6 allows the second shaft 45 to touch the inclined surface 4 b of the frame plate 4 when the second belt 2 receives tension. Therefore, as shown in FIG. 7 'When the rotating lever 47 is turned in the direction of the arrow, the second shaft 45 is rotated while touching the inclined surface 4b and moved up and down in the long hole 41a to form the second belt 2 slightly back. Roll. A belt pressing member 48 for holding the second belt 2 is provided below the first shaft 42. The belt pressing member 48 is rotatably supported on the frame plate 4. Therefore, the belt pressing member 48 presses the second belt 2 with one end to hold the second belt 2 between the first shaft 42 and the other end. The operation of the belt fastening tool 1000 in the aforementioned structure is described below. (Installation work) First, when the goods loaded in the box of the truck 50 are fixed, each end of the first belt 1 and the second belt 2 connected to the belt tightening tool 100 is fixed to the truck 50. On the side wall 50a. Specifically, as shown in the first to fifth figures, the first link is connected to the belt mechanism 6. This connection method is: the front end of the second belt 2 penetrates between the first shaft 4 2 and the belt pressing member 48 from the outside direction, and is lifted in the direction of the second shaft 4 5, and then is wound around the outer periphery of the second shaft 4 5 Pull it down toward the first shaft 4 2 -17- (13) (13) 200302194, and finally penetrate from the inside direction between the first shaft 42 and the belt pressing member 4 8 and tighten it. As a result, as shown in FIG. 11, once tension is generated on the second belt 2, the belt pressing member 4 8 is turned in the direction of the arrow and the upper surface is pressed against the first shaft 4 2-side to overlap the first and second layers. 2Belt 2 is held to prevent loosening. As shown in FIG. 1, when the first belt 1 is connected to the belt winding mechanism 5, the front end portion of the first belt 1 passes through the shaft members 7 a and 7 b of the belt winding shaft 7 from the outside. At the same time, the second belt 2 and the first belt 1 are tensioned tightly. # (Tightening operation) After the installation operation is completed, the holding member 23 is then held, and the handle 20 is turned forward and backward as shown in (a) and (b) of FIG. 2. When the handle 20 is turned in the closed and closed direction relative to the main body frame 3, as shown in FIG. 6, the engaging portion 25b of the first latch hasp 25 is engaged with the concave portion 10a of the first one-way clutch 8. As shown in FIG. 4, the outer ring member 10 receives a force that rotates in a blocking direction opposite to the direction of the arrow A. Furthermore, since the second one-way clutch 9 is not engaged with the first latch hasp 25, it does not receive the force in the locking direction. When the outer wheel member 10 of the first one-way clutch 8 is stressed in the blocking direction, the roller member 13 of the outer wheel member 10 is in the compression space portion 12-the spring becomes the old outer wheel member 10 and the inner wheel. The members 11 are in an independent state. As a result, with the handle 20, the outer wheel member 10 is rotated in an idling state relative to the inner wheel member 11. -18- (14) (14) 200302194 On the other hand, in the second one-way clutch 9, when tension is generated on the first belt 1, the direction of rewinding via the belt winding shaft 7 (the direction of the arrow A is the reverse direction) Direction) acts on the inner wheel member 11. Therefore, at this time, the outer ring member 10 is moved to the narrow side of the space portion 12 by the roller member 13 in the same manner as when the force is applied in the arrow direction A (opening direction), and the inner wheel is engaged by the roller member 13 The state of the member 11 and the outer ring member 10. At this time, the outer wheel member 10 of the second one-way clutch 9 is prevented from rotating by the second latch hasp 31 provided on the main body frame 3. Therefore, when the handle 20 is turned in the blocking direction, although the outer wheel member 10 and the inner wheel member 11 of the first one-way clutch 8 are free to move, the second one-way clutch 9 prohibits the belt winding shaft 7 from rotating, Therefore, the first belt 1 does not rewind. Therefore, when the first latch hasp 25 is in contact with the protruding portion 30a of the brake member 30, it is possible to inhibit the rotation in the lock direction. Next, as shown in FIG. 4, when the handle 20 is turned in the opening direction (arrow direction A), the outer wheel member 10 of the first one-way clutch 8 engaged with the first latching buckle 25 of the handle 20 is opened. Force in the direction. As a result, the roller member 13 is moved toward the narrow side of the space portion 12 to be in a state of engaging the outer ring member 10 and the inner ring member 11. Thereby, the belt winding shaft 7 pivotally supported on the inner wheel member 11 is rotated in the opening direction, and the first belt 1 is wound on the belt winding shaft 7. Therefore, as shown in FIG. 2 (i> m, no, the mouse is not turned in the opening direction, and the first belt 1 is wound around the belt winding shaft 7 and tension is generated. Furthermore, when the handle 20 is rotated, the first With the second latch buckle 2 5, 3, 1 will not make the impact of a spur gear like a conventional ratchet belt fastening device. 19- (15) (15) 200302194. After that, when tension is sufficiently generated As shown in FIG. 5, the lifting portion 25 a of the first latch hasp 25 can be lifted, and the front end of the first latch hasp 25 is set at a position higher than the protruding portion 30 a of the brake actuator 30. Therefore, when the handle 20 is turned in the locking direction again and exceeds the protruding portion 30 a, the first latch hasp 25 can be pulled down. As a result, the protruding portion 3 0a prohibits the first latch hasp 2 5 is in a state of turning in the open direction. As a result, the free end side of the handle 20 is used to approach or contact the rotation lever 47 of the belt release mechanism 6 to form a lock belt release mechanism 6 that can perform the release operation of the second belt 2 described later. (Release operation) As described above, the belt tensioning device 100 generates sufficient tension with respect to the first belt 1 and the second belt 2 When unloading the goods, the lock state of the belt release mechanism 6 can be released first by turning the handle 20 in the open direction. Then, as shown in FIG. 7, the rotation lever 47 of the belt release mechanism 6 is turned in the direction of the arrow. As a result, the second shaft 45 connected to the rotation lever 47 is rotated. At this time, as shown in FIG. 9, the second shaft 45 is greatly rotated due to the rewinding of the second belt 2. The tension springs and pushes in the direction of the first axis 4 2, and as shown in (a) and (b) of FIG. 8, the 4 5th rotation-moving side touches the inclined surface 4 b of the frame plate 4 while moving up and down in the long hole 41. Therefore, the second belt 2 is slightly reversed. Therefore, as shown in FIG. 9, the loosened portion of the second belt 2 can be pulled out between the first shaft 42 and the belt pressing member 48. Furthermore, the lever -20- (16) (16) 200302194 4 7 After returning to the original position and rotating again, the tension of the second belt 2 can be gradually reduced. After that, when the tension is sufficiently reduced, as shown in FIG. Lift the 5th side of the first latch hasp 25 to fully rotate the handle 20 in the opening direction. As shown in FIGS. 4 and 5, fit the front end of the first latch 2 25.

Furthermore, in this embodiment, the frame plate 4 is used as a plane substantially perpendicular to the axis of the long hole 4 1 a. However, it is not limited to this, and it may be a planar member provided on the frame plate 4 in parallel. Long holes and planes can also be provided in the frame plate 4 itself. In addition, the second shaft 4 5 of the belt tightening tool 100 of this embodiment is formed in a hexagonal shape in cross section except for both end portions. This portion has a structure that contacts the inclined portion 4 b of the frame plate 4. . Accordingly, the second belt 2 can be reliably wound. In addition, the second axis 4 5 does not need to be hexagonal in cross section, but can also be ___— polygons and circles that are more than two-sided, and `` '' '' v prepared circles ~~~ '—— Figure The 'shown' can also be cam-shaped. Further, it is preferable that the second shaft 45 is polygonal, elliptical, or cam-shaped in cross section at least at a portion where it contacts the inclined portion 4b. In addition, it is preferable that the second shaft 45 be subjected to a non-slip process such as knurling on the outer surface of the second belt -23- (19) (19) 200302194. Thereby, the winding of the 2nd belt 2 can be performed more reliably. The belt tightening tool 100 of this embodiment has a structure of a locking device that regulates the rotation of the second shaft 45. That is, as shown in Figs. 3 (a) and (b), 'the handle 20 is used as a locking device, and the handle 20 is used to form a locked state, and sufficient tension is generated on the first belt 1 and the second belt 2. After that, it is possible to prevent a decrease in tension due to the rotation of the second shaft 45. In addition, as shown in FIG. 14, the structure of the locking device may include a locking long hole 47 a formed in the inside of the rotation lever 47 and having a long diameter direction consistent with the longitudinal direction of the rotation lever 47; A locking plate 50 provided in the locking long hole 47a; a notch portion 41b formed on the loose supporting plate 41 and capable of engaging the front end portion of the locking plate 50. In this case, it is possible to use only the belt release mechanism 6 to change to the locked state without minding the state of the handle 2o. Further, in this case, the second shaft 45 may also be circular, but is rotatably supported on the main body frame 3. The belt easing mechanism 6 of this embodiment has a belt pressing member 48 (belt) which is rotatably supported on the main body frame 3 and presses the second belt 2 at one end to hold the second belt 2 between the first shafts 42 (belt Structure). Thereby, the loosening of the second belt 2 can be prevented. The winding mechanism 5 of the belt tightening tool 100 of this embodiment includes a belt winding shaft 7 which is supported on the main body frame belt, and a shaft supported on the body frame 3 coaxially with the belt winding shaft 7. Handle 20; the first one-way clutch 8 and the second -24- (20) (20) 200302194 one-way clutch 9 fixed on the belt winding shaft 7 and setting the idling state and the meshing state in the same direction; provided on the handle The first latch hasp 2 5 which is pushed on the belt winding shaft 7 side to be engaged with and disengaged from the first direction clutch 8 on 2 0; is provided on the main body frame 3 and is elasticized toward the belt winding shaft 7 side The second latch clasp 31 which can be engaged with and disengaged from the second direction clutch 9 is pushed. This makes it possible to reduce noise generated during the two operations of generating tension on the first belt 1 and the second belt 2 and releasing the tension. Furthermore, although the present embodiment has two mechanisms of the belt winding mechanism 5 and the belt unclamping mechanism 6, it is not limited to this, and it may have only one type of belt winding mechanism 5. Moreover, as shown in FIG. 15, the belt winding mechanism 5 may have the following structure: a belt winding shaft 7 which is supported on the main body frame 3 and winds the first belt; The handle 20 is coaxially supported on the main body frame 3; the ratchet 5 1 is fixed to the belt winding shaft 7; the handle 20 is provided on the handle 20 and is pushed toward the belt winding shaft 7 to be engaged with the ratchet 5 A first latch hasp 25 which is engaged and disengaged; and a second latch has 31 which is provided on the main body frame 3 and is pushed to the side of the belt winding shaft 7 to engage and disengage with the ratchet 51. In this case, the belt fastening device 100 can be simply constructed. [Industrial Application Possibility] The belt tightening device described above can be applied to the use of medium-sized fr fishing goods such as fixed trucks. 1 --- [Schematic description] Figure 1 is an oblique view of a belt fastening device. -25- (21) (21) 200302194 The second figure is an explanatory diagram showing the winding state of the belt fastening tool, (a) is a plan view state, and (b) is a front view state.
