Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spanner aiming to provide a plurality of locking portions for fitting nuts on the peripheral portion of a main body.

[0002]

[Prior art]

 A spanner in which two hooks are hooked on a single article is known. For example, a spanner is known in which an elongated plate piece is provided at both ends with hooking portions for fitting nuts of different sizes.

In addition, it is common practice to arrange a plurality of large and small spanners into a container.

[0004]

[Problems to be solved by devising]

 There is no single or single piece of the above-mentioned wrench, and when tightening or loosening a large number of nuts of different sizes, prepare a plurality of spanners and carry it with you. There was a problem that had to be solved. In addition, the spanner for the original nut usually has a different thickness of the hook depending on the size of the bolt to which the nut is screwed.However, such a consideration is required for the secondary spanner. Inevitably, there was a problem that it was difficult to use.

[0005]

[Means for solving the problem]

 However, the present invention solves the above-mentioned problems of the slave by providing the outer peripheral portion of the ring-shaped body or the plate-shaped body with a latching portion that fits a plurality of nuts (including bolt heads) of different sizes. is there.

[0006] That is, the present invention is a spanner in which a plurality of hooks that can be fitted with nuts of different sizes are provided on the outer peripheral portion of the ring-shaped body or the plate-shaped body. The spanner is characterized in that a plurality of locking portions that can be fitted with nuts of different sizes are provided, and the locking portions are recessed from the outer peripheral portion of the ring-shaped body toward the central portion.

In another invention, the outer shape of the ring-shaped main body or plate-shaped main body provided with a fitting hook portion such as a nut or the like, or the dish-shaped main body bent to one side is circular, elliptical, rectangular or other polygonal shape. The wrench is characterized in that it can be fitted with the nut of the ring-shaped body or the plate-shaped body.The thickness of the hooking portion is formed according to the thickness of the nut and the like. .

Next, another invention is a spanner characterized in that the number of hook portions to be fitted with nuts and the like provided in the main body is 3 to 11 and is fitted with nuts and the like provided in the main body. The shape of the latching part is a cutout type from the peripheral edge of the main body to the central part, a square hole type that penetrates from the lower surface to the upper surface, a square recessed type that penetrates, and a cutout width from the peripheral edge of the main body to the central part. It is a spanner that has a different notch step type.

The hooking portions in the above may be equally spaced or unequally spaced, but in a relatively small size, it is rational if the spacing is narrowed and the minimum necessary thickness is adopted in terms of strength. is there.

The outer shape in this invention is a circle, an ellipse, a square, or other polygonal shape, but it is not necessary to specify the shape as long as three or more hooking portions that fit into the nut can be provided. . However, because it is convenient to use, it is natural that it is easy to apply force, is easy to hold, and does not become extremely large.

The material of the wrench of the present invention is not limited to metal, but a required strength such as synthetic resin, carbon fiber molding, FRP, a composite of metal and synthetic resin (for example, embedding metal, embedding reinforcing bar). It is not necessary to limit the material as long as it is relatively lightweight and easy to fit in the hand.

[0012]

[Action]

 According to the present invention, since a plurality of hook portions that can fit with nuts are provided on the outer peripheral portion of the main body, it is possible to provide a spanner for operating a plurality of nuts with one article.

Since the shape is a ring shape or a plate shape, there is an advantage that handling is easy and force can be applied easily.

[0014]

Embodiment 1 An embodiment of the present invention will be described with reference to FIGS.

The circular portion 1a (for example, 10 mm) of the circular plate 1 having a diameter of 10 cm has the same thickness as the circular end portion, but within that range, the thickness becomes thinner toward the center, and the thickness of the central portion 1b becomes smaller. It is about 2 mm.

Further, the thickness of the circumferential portion 1a gradually increases from the maximum thickness of 10 mm to the minimum thickness of 2 mm in accordance with the circumferential angle (angle from the reference position), and is 350 degrees from one end. The maximum thickness is 10 mm, and then the thickness rapidly decreases (step 1c) and becomes 360 mm at 2 mm.

In the circumferential portion 1a, inner concave portions 3a, 3b, 3c ... 3x (hereinafter referred to as 3 as a whole) that come into contact with the four side walls of the nut 2 (or bolt head) from the circular end toward the center. Are provided at appropriate intervals (in the embodiment, 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k). Considering the strength, the space between the recessed portions 3 is wide for the large recessed portions 3a, 3b, etc., and 3k, 3i, etc. are narrow.

Although the number of the recessed portions 3 provided in the above-described embodiment is 11, the number is not limited, and if two discs provided with six recessed portions are set, 12 discs are provided, and if 3 discs are set, 18 discs are required. You can get a spanner 4 of different size.

In the above embodiment, one disk 1 is used, but if the outer diameter is large, it can be folded around the connecting shaft 5 as shown in FIGS.

According to the above-described embodiment, one disk spanner can rotate three or more nuts (as many as the recessed portions).

[0021]

Second Embodiment In the embodiment shown in FIG. 5, a spanner 7 is formed by providing hexagonal holes 6 (6a, 6b, 6c ... 6x) into which the large and small hexagon nuts can be fitted in the circumferential portion of the disc 1.

Also in this case, the smaller the hole diameter is, the thinner the thickness becomes, so that each part has an unequal thickness as shown in FIG.

However, it is conceivable that after the predetermined thickness (for example, 5 mm), the thickness is made equal, and there is no inconvenience even if the entire thickness is made equal. The wrench 7 is a disc 1 but may be a plate 8 having a non-circular shape as shown in FIGS.

Further, as shown in FIGS. 9 and 10, the disc 1 is a dish-shaped disc 11 with its circumferential portion being deflected to one side (upper side), and hexagonal holes 6 (6a, 6b, ... ) May be provided to make the spanner 12.

[0025]

Third Embodiment The embodiment of FIG. 11 is a spanner 10 provided with a hexagon recess 9 instead of the hexagonal through hole as shown in FIG. The method of using the spanner 10 in this case is the same as in the case of FIG.

[0026]

[Effect of device]

 According to this invention, the plate-shaped body or the ring-shaped body is provided with the latching portion for fitting a plurality of nuts of different sizes. Therefore, one spanner can rotate a plurality of nuts or bolts of different sizes. it can.

However, since there is a standard for the dimensions of the nuts, if hooking portions with dimensions conforming to the standards are successively arranged, it is possible to use the nuts of various sizes, etc., similarly to the universal spanner.
