Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tire chain mounting/storage box that can store a tire chain and also serves as a mounting stand during mounting.

(Prior art) Conventionally, in order to facilitate the installation of a tire chain, Utility Model Application Publication No. 66307 of 1971 provided a ladder-shaped lid with a butterfly plate on the main body of a tire chain installation device that could accommodate a tire chain. The lid has a groove so that a tire can be placed on the lid with the lid closed and a tire chain can be attached. It is provided so as to be able to freely extend forward with respect to the casing. An upwardly protruding body is formed on the front part of the bottom plate, and a recess for the tire is formed between the protruding body and the front end surface of the upper part of the casing, so that a chain can be stretched.

(Problems to be solved by the invention) However, there are various types of tire chains, such as a type in which a vertical cross chain is hung at a right angle between two horizontally separated main chains, or a type in which a diagonal cross chain is added to the above type (see Figure 5). Therefore, while the conventional structure is suitable for a tire chain with only a vertical cross chain, in the case of a tire chain having a vertical cross chain and a diagonal cross chain, there is a risk that the tire will always step on the diagonal cross chain when mounting the tire, and if it does, the tire chain will not be able to move, and in this state, it is difficult to adjust the movement of the tire chain in the horizontal and circumferential directions of the tire in order to mount the tire properly.

In addition, with the conventional type, when attaching a tire chain to a tire, the tire chain must be removed from the main body or case in which it is stored, and the removed tire chain must be unfolded and set on the mounting tool. For this reason, it takes time and effort to install the device, and there is a problem in that such work is forced on cold roads in winter.

The present invention was made to solve the above-mentioned conventional problems, and its purpose is to be able to be used with various types of tire chains, and to allow tire chains to be installed more accurately and more quickly. The aim is to make it easy.

(Means for solving the problems) Means for solving the above-mentioned conventional problems will be explained below using figures corresponding to embodiments.

(b) Lid plates 2 and 2' are installed at the upper ends of both short side plates 11a and 11b of the rectangular box body 1 with an open top.
that it was attached to a bow.

(b) At the center in the longitudinal direction of the box main body 1 is a cross chain that extends over the upper ends of both long side plates 12a and 12b, has a width narrower than the width of the tire chain 6, and has an overall length that is a cross chain in the longitudinal direction of the tire chain 6. 62
A tire receiving plate 4 shorter than 2 pitches in a is provided.

(c) The cover plates 2, 2' have their tip side surfaces 21, 2
1' was bent at an appropriate angle.

(d) The tire support plate 4 has support portions 41a, 41b raised diagonally upward from the center bottom portion 4a to the left and right with respect to the longitudinal direction of the box body 1, and both support portions 41a, 41b. The tip side is the box body 1
The transition portions 42a, 42b are bent toward the upper ends of the short side plates 11a, 11b.

(E) Notch grooves 41c and 41d are formed on both sides of the support portions 41a and 41b.

(F) Forming notches 42c and 42d at both ends of the transition portions 42a and 42b, and
The transition parts 42a, 42b and the support part 41
At least two through grooves 42e and 42f are formed across a and 41b.

The above technical measures have been taken.

(Function) When the tire chain 6 is not used,
In the case of a tire chain 6 consisting of main chains 61a, 61b and a vertical cross chain 62a, the second to third vertical cross chains 62a from one end of the tire chain 6 are connected to the bottom surface 4a of the tire receiving plate 4 in advance. Spread the tire chain 6 and place it on the tire receiving plate 4 so that it is located in the center of the tire (see Fig. 3), pass the main chains 61a and 61b on both sides through the notch grooves 41c and 41d of the support parts 41a and 41b, and then The remaining tire chain 6 is housed in the box body 1, and the lid plates 2, 2' are closed. In this state, the box body 1 is placed on a running surface close to the tires 5, and the lid plates 2, 2' are opened to bring the front end side surfaces 21, 21' into contact with the ground. Then, by starting the engine of the car and moving the car body, the tire 5 was raised from one side of the transition parts 42a, 42b from the cover plates 2, 2', and the tire 5 reached both the tops of the support parts 41a, 41b. (See Figure 4). When this tire 5 rises above the cover plates 2, 2', the tip side surfaces 21, 2
1' has sufficient pressure resistance and prevents the cover plates 2, 2' from sinking. Therefore, both ends of the tire chain 6 inside the box body 1 are connected to the short side plates 11a, 11 of the box body 1.
b Pull it out, and set the dimensions of the tire receiving plate 4 such that the width and total length in the vertical direction are shorter than the width of the tire chain 6 and two pitches of the cross chain 62a in the vertical direction, so that the tire chain 6 can be pulled out upward. Therefore, the main chains 61a and 61b are inserted into the notch 4.
2c, 42d, the main chains 61a, 61b spread outward,
The tire chain 6 is removed from the cutout grooves 41c and 41d to the outside, and the tire chain 6 is wound around the tire 5 around the tire receiving plate 4 without any trouble. When wrapped, the connecting points at both ends of the tire chain 6 are located on the side of the tire 5 where the vehicle body does not get in the way, and the hands can be used freely, so that the connecting parts 63 can be easily connected. Additionally, if the spacing between the cross chains 62a in the longitudinal direction differs depending on the type of tire chain 6, the connection points may vary and connection may be difficult, or the positional relationship of the tire chain 6 with respect to the width direction of the tire may vary. Since the driver does not step on the tire chain 6, the tire chain 6 can be moved within an appropriate range in the circumferential direction and width direction of the tire 5, and can be set at an optimal position.

Further, when using a tire chain 6 having a vertical cross chain 62a and an oblique cross chain 62b as shown in FIG.
61b and the vertical cross chain 62a, the diagonal cross chain 62b may also be inserted in advance through the through grooves 42e and 42f of the tire receiving plate 4.
The cross chain 62b is connected to the support part 41 at e and 42f.
a, 41b, so that the diagonal cross chain 62b is not stepped on by the tire. Furthermore, the notch grooves 42c and 42d of the tire receiving plate 4
are the main chains 61a and 61b of the tire chain 6
is provided so that it does not protrude to the side of the tire receiving plate 4 and sag.

(Example) Examples of the present invention will be described below based on the drawings. 1 is a rectangular box body with an open top, which has short side plates 11a, 11b and long side plate 12.

2 and 2' are lid plates hinged to the upper ends of the short side plates 11a and 11b with hinges 3 and 3', respectively;
The end side surfaces 21, 21' of the box body 2' are bent at an angle that opens outward to the extension line of the bottom surface of the box body 1 and becomes horizontal. Reference numeral 4 denotes a tire receiving plate provided at the center in the longitudinal direction of the box body 1 between the upper ends of both long side plates 12a and 12b.
The width of the cross chain 62a in the vertical direction of the tire chain 6 is set appropriately narrower than the width of the cross chain 62a, and the vertical length is set appropriately shorter than the two pitches of the cross chain 62a in the vertical direction of the tire chain 6.
is fixed across the long side plates 12a, 12b of the box body 1, and is raised diagonally left and right from both ends of the bottom surface 4a with respect to the longitudinal direction of the box body 1.
a, 41b, and transition portions 42a, 42b which are formed by bending both ends of the support portions 41a, 41b toward the upper ends of the short side plates 11a, 11b of the box body 1. Further, the support parts 41a, 41b have cutout grooves 41c, 41d formed on both sides, and transition parts 42a, 41d.
42b has a notch 42 cut out at both corners of its tip.
c, 42d, and transition portions 42a, 42d.
A plurality of through grooves 42e and 42f are formed across the support portions 2b and the support portions 41a and 41b. 5 is a tire, 6 is a tire chain, and the tire chain 6 consists of main chains 61a, 61b arranged mainly in parallel as shown in FIG. In addition, as shown in Fig. 5b, there is a type in which a diagonal cross chain 62b is added.
is connected. Note that some cross chains are arranged at angles other than the vertical and diagonal directions, that is, between the cross chains 62a that are parallel to the main chains 61a and 61b and in the vertical direction.

(Effect of idea) As described above, the present invention has the following effects.

(1) Since the lid plates 2 and 2' are hinged to the upper ends of both short side plates 11a and 11b of the box body 1, by opening the lid plates 2 and 2', you can move diagonally to the step between the box body 1 and the road surface. The cover plates 2 and 2' are installed, and by moving the car, the tires 5 can be lifted onto the tire receiving plate 4 provided on the upper part of the box body 1, and the tires 5 can be easily installed on the tire receiving plate 4.

(2) The tire receiving plate 4 has support portions 41a that stand up diagonally upward to the left and right with respect to the longitudinal direction of the box body 1,
41b, the supporting parts 41a, 41
The distance between the tire chains 6 is wide, and the cross chains 62a, 62b, etc. placed between the support portions 41a, 41b can be moved by a large amount, and therefore the movement of the tire chain 6 as a whole can be adjusted to a large extent.

(3) Furthermore, since the width of the tire receiving plate 4 is narrower than the width of the tire chain 6, and the overall length is shorter than two pitches of the cross chain 62a in the vertical direction of the tire chain 6, the tire chain 6 cannot be moved upward when it is installed. When moving, the main chains 61a, 61b
And the vertical cross chain 62a comes off without being caught by the tire receiving plate 4.

(4) The width of the tire support plate 4 should be made as wide as possible so that the tire 5 can ride on it safely. Therefore, when the width is about the same as the box body 1, if the tire receiving plate 4 does not have the notch grooves 41c and 41d, even if the tire chain 6 is set on the tire receiving plate 4,
Main chains 61a, 61b of tire chain 6
Since it has to be stepped on the tire 5, it cannot be placed on the tire receiving plate 4, and it protrudes from the side of the tire receiving plate 4 and hangs down. In order to prevent this, notch grooves 41c and 41d are provided, and the main chain 61
a and 61b to prevent it from hanging down from the tire receiving plate 4.

(5) Furthermore, notches 42c and 42d are provided in the tire receiving plate 4.
By providing the main chains 61a, 61
When lifting the main chains 61a and 61b, there are no corners so that they do not get caught, and the main chains 61a and 61b are
2c, 42d, the notch 42c,
42d, the main chains 61a, 61b automatically open into the notches 42c, 61b.
42d, which simplifies the device.

(6) Moreover, the notches 42c, 42 in the tire receiving plate 4
Due to the through grooves 42e and 42f of d, even if the tire chain 6 has a diagonal cross chain 62b, the tire 5 does not step on it, and the tire chain 6 can freely move in the width and circumferential direction within a certain range. Since it can be installed at the best position, it can be used with tire chains 6 of different types.

(7) Furthermore, in the case of the present invention, even if the tire chain 6 is set on the tire receiving plate 4 in the box body 1 in advance, the cover plates 2 and 2' can be closed, so that the box can be stored so that it can be installed at any time. It is easier and faster to install than conventional devices.
