JPH01122710A - Auxiliary mounting fixture for tier anti-slip gear - Google Patents

Abstract

PURPOSE:To facilitate the locking of a mounting fixture made of a resilient material to a hook of a device body by using an auxiliary mounting fixture composed of a grip section adapted to be gripped by the worker and a hook section adapted to be engaged with the hook when the mounting fixture is locked with the hook of the device body. CONSTITUTION:An auxiliary mounting fixture 14 is formed in such a way that a metal wire is bent so as to have a circular gripping section 16 at one end and a U-like hook section 18 at the other end. Meanwhile, a tire anti-slip gear 22 is laid along the tread surface in the outer peripheral section of a tire 24, having at its one end several hooks 26 intermittently provided and adapted to be engaged with a stretched rubber ring 2 so that the anti-slip gear 22 is press-fitted on the tire 24. When the rubber ring 20 is engaged to the hooks 26, the auxiliary mounting fixture 14 is used. That is, the worker grips the gripping section 16 so as to engage the rubber ring 20 with the hook section 18, and thereafter the rubber ring 20 is stretched by means of the gripping section 16 so as to be locked to each of the hooks 26.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for attaching a tire anti-slip device to a tire.
The present invention relates to an attachment aid for a tire anti-slip device that is used to hang an attachment device made of an elastic material such as a rubber ring to a hook attached to a tire anti-slip device.

[Prior Art] In a tire slip prevention device that is arranged so as to wrap around the outer circumference of a tire, with the longitudinal direction being the tire circumferential direction, hooks are intermittently attached to one end in one width direction along the longitudinal direction. When the tire anti-slip device is placed on the tire, the hooks are intermittently arranged in an annular shape on the outer side of the tire. Then, by hooking an attachment device made of an elastic material such as a rubber ring to this hook, the tire slip prevention device comes into contact with the tire under pressure due to the biasing force of this attachment device, and becomes attached to the tire. .

However, the work of hooking the mounting tool to the hook is performed by the mounting operator, but since this work is done while elastically stretching the mounting tool, the work requires force.

However, as shown in FIG. 11, since the tire anti-slip device 2112 is located near the opening of the hook 10, the rubber ring 13 serving as the attachment device must be gripped with the hand metal body as shown in the figure. Even if you try to hang it on the hook IO, there is a distance MA between the end of your hand and the rubber ring 13, so you cannot hang it on the hook IO.

Second, the work of hanging the rubber ring 13 on the hook 10 was done with the tips of the fingers, and it was not an easy work because it required a lot of force.

Moreover, there are usually a plurality of rubber rings 13 (generally 2 to 3
Since the book (book) is hung on one hook 1O, it is easy to get your fingertips caught between the rubber ring 13 that was hung earlier, as shown in Figure 12, and you have to be careful when working. There was no work involved.

[Problems to be Solved by the Invention] In view of the above, the present invention provides a tire anti-slip device that can easily hook a mounting tool made of an elastic material to a hook attached to the tire anti-slip device. An object of the present invention is to provide a mounting aid for a tire anti-slip device, which is used for hooking a mounting tool made of an elastic material to a hook attached to a tire anti-slip device, and which comprises: It is configured to include a grip part that is held by the mounting operator, and a hook part that engages with the mounting tool, so that the mounting tool can be handled remotely.

[Embodiment] FIG. 1 shows a first embodiment of a mounting aid for a tire anti-slip device according to the present invention. The mounting aid 14 of this embodiment is formed by bending and shaping a single metal wire, and has an oval grip portion 16 formed at one end and a U-shaped grip at the other end. A bent hook portion 18 is formed. The hook portion 18 is 1 when the mounting aid 14 is viewed from above in the figure.
The grip part 16 is in a state perpendicular to the direction of the pitcher's force (see Fig. 3), and the opening width of the hook part 18 is set to be larger than the diameter of the rubber ring 20 as the attachment tool. .

At least the hook portion 18 of the mounting aid 14 is coated with a material having a low coefficient of friction such as fluororesin or hard urethane resin.

As shown in No. 215!1, tire anti-slip equipment 2
2 is formed in a net shape from a rubber material, and is arranged on the outer periphery of the tire 24 with the pitching force direction along the circumferential direction of the tire 24, and both ends in the longitudinal direction are connected to each other to form an annular shape. A hook 26 is intermittently attached to one end of the tire anti-slip device 22 in the width direction along the direction of the pitcher's force. These hooks 26 are arranged in a ring on the outer side of the tire 24 when the tire anti-slip device 2 is placed on the tire 24 as described above.

Anti-slip tires? t5122, the rubber ring 20 is hooked to all the hooks 26 in a tensioned state, so that one end in the width direction is biased toward the center of the annular shape, and thereby the tire 2
2 in a pressed state and comes into contact with the tire 22.

Next, a description will be given of the operation of hooking the rubber ring 20 to the hook 26 of the tire anti-slip device 22 shown in FIG. 2 using the mounting aid 14 of this embodiment.

This operation is initially performed by directly grasping the rubber ring 20 with the fingertips without using the attachment aid 14. When the rubber ring 20 is hooked to a suitable number of hooks 26 at regular intervals as shown in FIG. 2, it will not fall off from the hooks 26.

Use of the mounting aid 14 is started from this state. The attachment aid 14 is operated by gripping the gripping part 16, and the rubber ring 20 is hung on the hook a118 by operating the first gripping part 16, as shown in FIG. If the mounting aid 14 is moved upward in the figure from the state shown in FIG. 1, the rubber ring 20 can be elastically stretched. It can be guided to the hook 26 and hung on the hook 26.

In this case, since the hand of the mounting operator is at a position away from the hook 26, even if he or she is forcefully grasping the grip part 16 with the hand metal body, there is no problem with the work, and the work can be done in a state where it is easy to apply force. .

The same operation as above is repeated, and the rubber ring 20 is sequentially hooked to all the remaining hooks 26.

When hanging a plurality of rubber rings 20 on the hook 26, as shown in FIG. 18 may get pinched, but the wearer's fingertips are not pinched, so they can work without worrying about answering questions. Furthermore, in the case of this embodiment, at least the hook portion 18 is coated with a material having a low coefficient of friction, so even if it is sandwiched between two rubber rings 20, it can be easily extracted.

FIG. 4 shows a mounting tool 30 made of an elastic material such as rubber and having a shape different from that of the rubber ring 20.

As shown in FIG. 5, this mounting tool 30 is configured such that eye portions 34 formed at the tips of radially arranged legs 32 are hooked to hooks 26.

The mounting aid 14 of the above embodiment can also be used when hooking the mounting tool 30 to the hook 26. That is,
As shown in FIGS. 7 and 8, by hooking the hook portion 18 to the base of the eye portion 34, the eye portion 34 can be guided to the hook 26 by operating one gripping portion 16.

In the case of FIG. 5, the mounting tool 30 is used together with two wooden rubber rings 20, as shown in detail in FIG.

In the above embodiment, the mounting aid 14 is formed from a metal wire rod, so if the entire surface is coated with a material having a low coefficient of friction, the feel of the gripping portion 16 will be improved, and the overall rust-preventing effect will be produced. Further, the mounting aid 14 itself may be molded from resin such as fluororesin or hard urethane resin.

FIG. 9 shows a second embodiment of the invention. In the mounting aid 14 of this embodiment, the grip part 16 is cylindrical, and a pair of hook parts 18 are provided spaced apart from each other in the longitudinal direction of the grip part 16. This attachment aid 14 is made by bending and forming a single metal plate, or by melting and bonding a grip part 16 formed from two metal plates and a part where a pair of hook parts 18 are formed. It is also made of integrally molded material such as fluororesin or hard urethane resin.

In this mounting aid 14, as shown in FIG. 1O,
The hook 26 can be positioned in the gap formed between the pair of hooks 18, and the rubber ring 2
0 can be supported more stably, making the work easier than in the previous embodiment.

[Effects of the Invention] As explained above, the mounting aid for a tire anti-slip device according to the present invention facilitates the work of hooking a mounting tool made of an elastic material to a hook attached to a tire anti-slip device. It has the effect of
