Tool for connecting and separating quick-release chains

This creation is about a chain tool, especially a tool that links and separates quick-release chains.

As shown in Fig. 14, the conventional chain tool is mainly composed of two structurally identical wrenches 91. The trigger body 91 has two grooves 92 at one end to form a chain hook 93 and two positions in the chain hook 93. The side block 94 and the side hole 95 allow the two triggers 91 to abut and can be pivoted relative to each other, and can be used for the disassembly and assembly of the chain 96. At this time, the two triggers 91 put the chain hooks 93 into the chain. The roller 961 is held against the 96, and the side blocks 94 on both sides are only positioned outside the chain 96 to provide an auxiliary positioning of the chain.

As shown in Fig. 15, if the chain 96 is to be disassembled, the rollers 961 to which the two-chain hooks 93 are to be abutted must be close to each other. At this time, the two triggers 91 can be docked with the side holes 95, and the force is pivoted to allow two The chain hooks 93 are relatively close, and the two rollers 961 are relatively close to each other with the chain hooks 93, so that the chain 96 can be disassembled; as shown in Fig. 16, if the chain 96 is to be assembled, the two chain hooks 93 must be The second roller 961 is relatively far away. At this time, the two trigger bodies 91 can be reversed, and then the side holes 95 are butted and biased. At this time, the chain hooks 93 of the two trigger bodies 91 are away from each other, and the second roller 961 is followed. The chain hook 93 is driven relatively far away, so that the chain 96 is restored to the fixed state by the disassembled state.

However, when the chain 96 is assembled, the two triggers 91 can be pivoted to be biased by the chain hooks 93 to drive the two rollers 961 relatively apart, but the side holes 95 are docked. When the distance between the two chains 93 is greater, The force exerted by the roller 961 will be greater in the component of the downward direction, but the component in the downward direction does not help to keep the two rollers 961 relatively far apart, and the side that can actually keep the roller 961 relatively far away The component force is relatively small, and it can be expected that a larger force must be applied to generate a larger lateral component, and the second roller 961 has a relatively distant action, thereby causing laborious and time consuming assembly of the chain 96. The problem of half the effort, this is the focus of this creative work.

The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings.

Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

Please refer to FIG. 1 to FIG. 13 for the preferred embodiment of the present invention, which is for illustrative purposes only and is not limited by the embodiments described herein.

The present invention provides a tool for joining and separating a quick-release chain. As shown in FIG. 1, the chain 1 is a plurality of pairs of the outer link plate 11, the inner link plate 12 and the pair of quick-release link plates 13 respectively abutting with the chain shaft 14 Connected, each chain shaft 14 is provided with a roller 15 having a first spacing D1 between the pair of quick chain links 13 and a second spacing D2 between any pair of inner chain plates 12, the second spacing D2 being smaller than the first spacing D1. When the chain 1 is to be disassembled, the rollers 15 provided by the two chain shafts 14 at the quick-release link plate 13 must be brought close to each other, and the pair of quick-release link plates 13 can be detached from the chain 1; When the chain 1 is assembled, the rollers 15 provided on the two chain shafts 14 at the quick chain link 13 are separated from each other, and the pair of quick link plates 13 can be returned to the chain 1.

As shown in Figures 2 to 3, the trigger body 2 has a plurality of chain hooks at one end and has side holes 21 for docking, and the plurality of chain hooks are bent toward the same side at one end of the trigger body 2 and are juxtaposed to be claws. In the shape, the wrench 2 is bent with the plurality of chain hooks to form an arc-shaped curved surface 22 on the back side.

In the plurality of chain hooks of the trigger body 2, at least one of the first chain hooks 23 has a first width W1 which is approximately equal to the first spacing D1, and can be placed between the pair of quick-release chain plates 13 to resist Roller 15; a second chain hook 24 having a second width W2 that is approximately equal in width to the second pitch D2, and can be placed between any pair of inner link plates 12 to resist the roller 15, the first width W1 and Greater than the second width W2.

As shown in FIGS. 2 to 3, the trigger body 2 of the present embodiment has a first chain hook 23 and a second chain hook 24, and has a side block 25 and a first chain hook 23 and a second chain hook 24 side by side to The side block 25 provides an auxiliary positioning of the installed chain 1 next to the first chain hook 23.

When the tool of the above embodiment is used for disassembling the chain 1 as shown in FIG. 4, the first chain hook 23 and the second chain hook 24 of one of the trigger bodies 2 are the first chain hooks of the other trigger body 2. 23 is opposite to the second chain hook 24, and is pivoted by the two trigger bodies 2 by the side holes 21, and the second chain hook 24 of the trigger body 2 is placed beside the pair of quick release chain plates 13 The inner chain plates 12 are placed to resist the rollers 15, and the second chain hooks 24 of the other trigger body 2 are placed between the inner link plates 12 on the other side of the pair of quick release link plates 13 to resist the other rollers. 15. After the force is applied, the two rollers 15 that are in contact can be relatively close to each other, and the chain 1 can be disassembled. This portion is substantially the same as the conventional wrench 91 in which the chain 96 is disassembled.

The tool of the above embodiment, when used in the assembly of the chain 1 , is different from the conventional method of assembling the chain 96 by the conventional wrench 91. After the two plates 2 are reversed, they are not docked by the side holes 21, for example. As shown in Fig. 5, the first chain hook 23 and the second chain hook 24 of one of the trigger bodies 2 are opposite to the first chain hook 23 and the second chain hook 24 of the other trigger body 2, and as shown in Fig. 6. It is shown that the first chain hook 23 of a wrench 2 is placed between the pair of quick-release link plates 13 to resist the roller 15, and the second chain hook 24 of the other trigger body 2 is inserted into the pair of quick-release chains. The inner chain plate 12 is located on the side of the plate 13 to abut against the other roller 15. At this time, the positions of the two trigger bodies 2 in the width direction are not aligned, but are staggered so that the first chain hook 23 of one trigger body 2 is aligned with the other. The second chain hook 24 of the body 2, at this time, the curved faces 22 of the two wrenches 2 abut against each other, and after the force is applied, the two rollers 15 that are pressed against each other can be relatively separated, and the chain 1 can be fixed.

It is not difficult to find out from the above description that the above-mentioned chain 1 is assembled, and the first chain hook 23 of one of the trigger bodies 2 is placed between the pair of quick-release link plates 13 to resist the roller 15, and the other The second chain hook 24 of the trigger body 2 is placed between the inner link plates 12 on the side of the pair of quick release link plates 13 to abut against the other roller 15 in comparison with the state in which the chain 96 is assembled by the conventional second trigger body 91 ( As shown in Fig. 16, the distance between the first chain hook 23 and the second chain hook 24 of the second assembly 2 of the present invention when assembling the chain 1 is closer than the distance when the two chain hooks 93 are assembled with the chain 96, so The created trigger 2 can provide the lateral force of the roller 15 relatively far away from the conventional two-part 91, so that the lateral force can be relatively reduced, and the lateral force can be generated. Since the roller 15 is relatively far away, when the chain 1 is assembled, the effect of saving effort and time-saving can be achieved.

Of course, there are still many examples of this creation, only the details change. Please refer to the seventh embodiment of the present invention, which is the second embodiment of the present invention. The main difference between the first embodiment and the first embodiment is that each of the trigger bodies 2 has two first chain hooks 23 and a second chain hook 24, and two The first width W1 of the chain hook 23 is equal in width to correspond to the chain of the quick chain link of the same first pitch D1.

When the tool of the embodiment is used for assembling the chain 1, the second wrench 2 is also reversed, and the first chain hook 23 and the second chain hook 24 of a wrench 2 are combined as shown in FIG. The first chain hook 23 of the other trigger body 2 and the second chain hook 24 are opposite each other, and the first chain hook 23 of the trigger body 2 is placed between the pair of quick release link plates 13 to resist the roller 15, and the other The second chain hook 24 of the trigger body 2 is inserted between the inner chain plates 12 of the pair of quick release chain plates 13 to resist the other roller 15, and the two trigger bodies 2 are also staggered to allow a trigger body 2 The first chain hook 23 is aligned with the second chain hook 24 of the other trigger body 2, and is also abutted against each other by the curved surface 22 of the two trigger body 2, and the two rollers that can be resisted are also applied after the force is applied. 15 is relatively far away, and the chain 1 can be fixed.

In this embodiment, in addition to the same function as that of the first embodiment, since the trigger body 2 has two first chain hooks 23, the operator can assemble the chain 1 into the two first chain hooks 23 Alternative use (as indicated by the solid and dashed lines in Figure 9) can further increase the flexibility of tool operation.

Referring again to FIGS. 10 to 13, which is the third embodiment of the present invention, and the main difference between the first and second embodiments is that the trigger body 2 has two first chain hooks 23, 23A and a second chain hook 24. The first width of the first chain hooks 23 and 23A is such that the first chain hook 23 is wider and still has a first width W1, and the first chain hook 23A is narrower and has a first width W3 to correspond to the first spacing. Different fast chain links chain 1. In other words, when the chain 1 has different widths, the most common one is that the chain has a wide and narrow width due to different speeds, the higher speed chain has a narrower width, and the lower speed chain has a wider width. Width, at this time, because the first chain hook 23 and the first chain hook 23A have different first widths, as shown in FIG. 12, the first width W1 of the first chain hook 23 of the embodiment is suitable for the 9th speed. The chain 1 of the first spacing D1 of the chain link 13 is further shown in Fig. 13, and the first width W3 of the first chain hook 23A is a chain 1 suitable for the first pitch D3 of the 11-speed quick-release link plate 13, The 11-speed or 9-speed chain can be disassembled or assembled by the second trigger 2, and the same function as the first embodiment can be achieved, and the flexibility of the tool operation can be further increased because the chain of different specifications can be applied. degree.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
