Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a latching tool that is attached to the wheels of automobiles traveling in snowy, cold regions, etc., and is used to hang various types of anti-slip devices such as chains that cover the outer circumferential surface of the tires. and relating to latching rings.

BACKGROUND OF THE INVENTION Conventionally, tire chains have been used in automobiles traveling on rough roads such as snowy, cold regions or muddy areas in order to prevent slips and ensure smooth running. As such a chain, generally, two long side chains each having a hook at one end are connected to each end of a plurality of short main chains, and when stretched out, it becomes a ladder shape.

Problems to be Solved by the Invention However, it is not easy to attach this chain to a tire that is stopped on the road. This is because when installing, first place the main chain that is furthest away from the hook end into the wedge-shaped contact gap formed between the road surface and the outer circumferential surface of the tire, so that the center of the entire chain is at the top of the tire. Place the tires so that they are approximately on the same position, hang each hook on the ring at the optimal position on the other end of the side chain to which they are connected, and then use rubber bands with hooks to place the hooks on the outside of the tire. This is because the hook must be hooked onto the side chain, held in place, and tightened to prevent it from becoming loose.At this time, especially inside the tire, the hook and the other end of the side chain must be tightened between the tire, the vehicle body, and the shaft. Since the work is carried out in the narrow space below, it is necessary to twist the upper body to get into the space under the car body, and perform unnatural work with only one hand, making it difficult to see hooks etc. Therefore, the effort is large; It takes a long time and the work is difficult.To avoid these difficulties, there are methods such as stretching the chain on the ground and moving the car to install it, or jacking up the tire. .

However, all of these methods are not difficult if they are carried out in a place with good road conditions, but once you enter a snowy, cold region, muddy or other bad road and a slip occurs, it becomes very difficult. Become. Note that tire chains are heavy, so if you drive with them loose, centrifugal force will act on them and hit the mudguards, causing not only an impact noise but also damage to them. As described above, since it is always difficult to attach tire chains, spiked tires have rapidly become popular. However, to improve performance, spiked tires use cemented carbide alloys such as titanium for the pin tips, which scrape the pavement surface and create dust pollution, which is a serious problem in snowy, cold regions.

The present invention was made in view of these conventional problems, and it is an object of the present invention to provide a latching device and a latching ring that can easily attach various types of anti-slip devices such as chains to tires. shall be.

Both can be easily disengaged and removed from the edge 32 of the wheel 28 by applying force.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a front view showing an embodiment of the anti-slip latching device according to the present invention, and FIG.
The figure below shows a ring-shaped bar spring. In the figure, 10 is a retaining ring, 12 is the ring body, and 14 is a plurality of hooks arranged there. The outer diameter of the ring body 12 is sized to fit inside the edge of the wheel to which it is mounted. However, it is preferable that its outer diameter be slightly smaller than the inner diameter of the wheel edge. Also, the ring body 12
The inner diameter of the brake should be large enough so that it does not interfere with the axle, brake drum, etc. when installed. Therefore, it can be easily manufactured by using, for example, a metal plate and cutting it out from there. Further, the number of hooks 14 provided on the ring body 12 is, for example, eight, and they are arranged at equal intervals along the ring. At that time, each hook 14 is made of metal, for example, and after each of their base end portions 15 is fixed to one surface of the ring body 12 by welding or the like, the hook 14 is once raised diagonally upward from the center of the ring width. It is preferable to make the hook portion 16 by bending it parallel to the plane and bending the tip upward (see FIG. 7).

Reference numeral 18 denotes a bar spring having a ring-like shape and a rectangular cross section, which attaches the retaining ring 10 to the wheel.

This spring 18 has an opening 20 in a part of the ring,
Make its outer diameter slightly larger than the maximum inner diameter of the wheel. At both ends facing the opening 20, hooks 22 and 24 are formed which are bent inward. Note that the cross-sectional shape of the rod spring can be changed as appropriate.

Such a retaining ring 10 and a ring-shaped bar spring 18
The anti-slip latches 26 can be attached to wheels as appropriate. However, in order to attach it to the inside of a wheel, the wheel must be removed from the axle and attached to that wheel. For this reason, it is usually worn on a sunny day when there is plenty of time, prior to snowfall or freezing. At that time, after placing the wheel horizontally on a road surface, etc. with the mounting side facing up, a hook is placed on the inside of the edge 32 of the rim 30 that forms the peripheral area of the wheel 28, as shown in FIG. Body 1 of retaining ring 10
Insert and place 2. Note that the circle on the outside of the rim 30 is the outline of the tire 34. Then, using the ring-shaped rod spring 18, the diameter of the spring 18 is reduced by narrowing the space between them using the hook portions 22 and 24, and the diameter of the spring 18 is reduced, as shown in FIG. It is fitted along almost the entire circumference, its outer circumferential portion (locking portion) is elastically contacted with the edge 32 of the wheel 28, and the inner circumferential portion (supporting portion) is held against the outer circumferential portion of the ring body 12. To support. Generally, the edge 32 of the wheel 28 will be slightly outwardly curved to form an inward arc into which it will fit. In this way, the anti-skid catch 26 is attached to the wheel 2
8 can be easily and firmly attached. Then, attach the wheels to the axle. Anti-slip latches 26 when driving
They don't get in the way, and they don't detract from the car's appearance because they're usually not visible when mounted inside the wheels. Note that the anti-slip latches 26 can of course also be attached to the outside of the wheel.

After that, if there is snow or ice and it is necessary to prevent slipping, a non-slip device is appropriately hung on the hook portion 16 of each hook 14 provided on the latching ring 10 to cover the outer peripheral surface of the tire 34 and stop it. . At this time, anything that can be hung on the hook 14, such as a chain, rope, or rubber band, can be used to prevent slipping. Further, hooking work can be easily carried out by simply bending down from the outside of the wheel, inserting the hand inside the tire 34 over the outer peripheral surface, and searching for the hook portions 16 of each of the seven hooks 14. This is because the hooks 14 are arranged, for example, at equal intervals along the edge of the wheel 28, so that it is sufficient to grope them without checking with the naked eye. Incidentally, in order to cover the contact surface of the tire 34 with the road surface etc. with a non-slip coating, it is sufficient to cover the other surfaces and then move the vehicle slightly.

Therefore, a chain 3 as shown in Figure 4 is used to prevent slipping.
When four chains 36 are used and are attached to the outer peripheral surface of the tire 34, the arrangement of each chain 36 is shown in FIG. 5 on the inside of the wheel and as shown in FIG. 6 on the outside. Also, Figure 7 shows the 5th
FIG. 3 is an enlarged sectional view taken along line XX in the figure. In this way, both ends of each chain 36 are hung on the hook portion 16 of each hook 14,
After covering the outer circumferential surface of the tire 34, using a rubber band 38 with four hooks and hooking the hooks 40 to the intermediate ring 42 of each chain 36, tension is applied directly to each chain 36, so that each chain 3
The mounting condition of item 6 is now good and no loosening occurs. In addition,
The number of chains 36 to be attached is changed as appropriate depending on the amount of snowfall and the like. Furthermore, it may be changed to other types of anti-slip.

In the non-slip latching tool in the above embodiment, a ring-shaped rod spring was used as the latching ring mounting body, but a plate spring 44 having an S-shaped cross section and an appropriate length as shown in FIG. 8 is used. You may. This plate spring 44 consists of a connecting part 46 bent into an arc shape matching the shape of the edge 32 of the wheel 28, and a supporting part 48 connected thereto. Therefore, when the edge 32 of the wheel 28 is pushed into the space inside the locking portion 46, the locking portion 46 covers the edge 32, as shown in FIG. The supporting portion 48 contacts the outer peripheral portion of the retaining ring main body 12 from the outside with one surface thereof so as to support the outer peripheral portion of the retaining ring main body 12 . Therefore, along the ring body 12,
For example, four plate springs 44 are arranged at equal intervals. When the supporting portions 48 of the plate springs 44 are fixed to the ring body 12 by welding or the like, the retaining ring 10 and the plate springs 44 become one piece, making it easy to handle and attach to the wheel 28.

Further, although the anti-slip latching devices in each of the above embodiments all use a latching ring mounting body, it may be omitted. In that case, a retaining ring 50 as shown in FIG. 10 is constructed. That is, the ring main body 52 is partially provided with an opening 54, the outer diameter of the main body 52 is made slightly larger than the maximum inner diameter of the wheel 28, and the main body 52 itself is made into a spring.

In addition, through holes 56 are provided at both ends facing the opening 54.
, 58 are provided. Note that a plurality of hooks 60 are appropriately arranged on the ring body 52. When such a non-slip retaining ring 50 is narrowed down to the diameter of the ring body 52 using the through holes 56 and 58 or the two hooks 60 in the vicinity, the anti-slip retaining ring 50 can be attached to the inside of the edge of the wheel 28. Since it can be fitted along almost the entire circumference and the outer circumferential portion can be brought into contact therewith and stopped, it is easier to handle and to attach to the wheel 28.

In this way, when the non-slip chain 36 or the like attached to the wheel, its latching tool 26, the latching ring 50, etc. are no longer needed, the non-slip can be removed from the hooks 14, 60 and the tire 36 is removed.
4, and can be easily removed from the latching tool 26 and the latching ring 5.
0 is a locking portion 44 and a ring-shaped bar spring 1, respectively.
8. Both can be easily removed from the wheel 28 by applying a force to the ring body 52 etc. that resists their spring force.

Effects of the Invention According to the invention described above, the retaining ring with the hook has the outer diameter of the ring body large enough to fit inside the edge of the wheel, and the ring attachment body has an elastic member attached to the edge of the wheel. Since it has a locking part that comes into contact with the ring and a support part that supports the locking ring, it can be easily attached to and removed from the wheel.

In particular, if it is attached to the inside of the wheel, it will not get in the way when driving and will not spoil the appearance, so it can be left attached regardless of whether it is snowing or not. When it is necessary to prevent slips due to snowfall, etc., select the appropriate anti-slip material from various types of chains, etc., and attach it to the outer circumferential surface of the tire by simply hanging it on a hook.
When it is no longer needed, it can be easily removed from the hook, which is convenient and reduces the burden on the operator.

If a ring-shaped rod spring is used as the retaining ring attachment, the entire body can be squeezed using the opening.
It is easy to attach and detach from the edge of the wheel, and because it fits inside the edge of the wheel along almost the entire circumference, the retaining ring can be firmly fixed, and it does not protrude outside beyond the edge of the wheel. , does not get in the way, and no unnecessary force is applied from the outside.

If the ring body of the latching ring with the hook itself is made of a spring, the latching ring mounting body is not required, and handling becomes easier.
