Abstract

(57) [Summary] [Purpose] Providing a wrench handle with an anti-slip function. [Structure] In a handle 1 of a wrench provided with convex display plate bands on both sides, a central portion 3 of the display plate bands on each side is left as a portion necessary for display, and the central display portion 3 is used as a boundary. Anti-slip groove 5 having an arbitrary shape is formed on both side portions 4A and 4B at regular intervals to prevent slippage defined by the concave groove 5 on both side portions 4A and 4B of the display plate band. By positively giving the concave-convex shapes 6A and 6B for use, when using, attach the thumb to the concave-convex shapes 6A and 6B and firmly and firmly grip the handle 1 to securely hold the handle 1 in the predetermined direction. Since it can be rotated, it is possible to eliminate the concern that the thumb easily slips from the surface of the display plate band and deteriorates workability as in the conventional case.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the handle of various wrenches (including spanners) that are widely used as work tools.

[0002]

[Prior Art]

 The handle of this type of conventional wrench, whether it is for double or single use, is usually provided with a convex display plate band on substantially the entire area in the longitudinal direction on both side faces thereof, and the display plate bands on both sides are provided. There are many necessary markings such as trademarks, sizes, materials and JIS marks. This is, of course, required for each of the above-mentioned indications in the distribution of the wrench, but the thickness of the handle itself is set to a thickness suitable for gripping, or the design is required. It's nothing but trying to respond. For this reason, in general, the surface of such a display plate band is actively subjected to mirror finishing by polishing or the like so that the above-mentioned respective displays can be clearly recognized.

[0003]

[Problems to be solved by the device]

 However, the appearance of the conventional wrench can be greatly improved due to the presence of the above-mentioned display plate band and its mirror surface processing, but in actual use, on the contrary, these are not Inconvenient for use. When using the wrench, the operator attaches his thumb to the surface of the display plate band and rotates the handle in a predetermined direction. If it is wet with oil or sweat, the mirror surface of the display plate band will be damaged, and the fingers will slip easily, making it difficult to grip the handle strongly. Therefore, in various conventional wrenches, regardless of their size and shape, this point is regarded as a problem in use.

[0004]

The present invention was developed in order to effectively solve the problem of the handle of the conventional wrench, and is provided with convex display plate bands on both sides. Assuming the wrench handle, the center part of the display plate strip on each side is left as a part necessary for display, and concave grooves of arbitrary shape are provided at regular intervals on both sides of the center display part as boundaries. In this case, a configuration is adopted in which the anti-slip concavo-convex shape defined by the concave groove is positively provided to both sides of the display plate band.

[0005]

[Action]

 Therefore, according to the present invention, when viewed as a whole, the convex display plate bands similar to the conventional ones still exist on both sides of the handle, which is suitable for grasping the handle itself. It is possible to ensure sufficient wall thickness or to meet design requirements, but in reality, it is necessary for the side parts except for the central display part left as a part necessary for display. As a result, the uneven shape for slip prevention defined by the groove is positively provided.When using the uneven shape, hold the handle firmly with your thumb and hold the handle firmly. Since it is possible to rotate the thumb in a predetermined direction, it is possible to eliminate the concern that the thumb easily slips and deteriorates workability as in the conventional case.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail based on an illustrated embodiment, and the illustrated embodiment is applied to a handle of a combination wrench among various wrenches. To explain this concretely, as shown in FIG. 1, the combination wrench itself according to the present embodiment is provided with a box end type tightening port 2A on one end side of the handle 1 and an open end on the other end side. It is premised that the mold clamping holes 2B are provided, and in principle, the same convex mirror-finished display plate bands as in the conventional case are provided on both side surfaces of the handle 1. However, in the present embodiment, unlike the conventional case, the convex strips provided on the both sides of the handle 1 over substantially the entire area in the longitudinal direction are not intended to be used as they are as the display plate strip. However, as shown in FIG. 2, while the central portion 3 of the display plate band is left as a portion necessary for display, both side portions 4A and 4B with the central display portion 3 as a boundary have a plurality of arbitrary shapes. The recessed grooves 5 are continuously formed at regular intervals, and the both sides 4A and 4B are provided with the uneven shapes 6A and 6B for slip prevention defined by the recessed grooves 5. The point is that the configuration is adopted.

Therefore, even in the combination wrench of the present embodiment, when viewed as a whole, the same shape of the convex display plate band as that in the conventional case still exists on both side surfaces of the handle 1, so that the handle The thickness suitable for gripping 1 itself can be sufficiently ensured, or it is possible to satisfy the design requirement, and the central display portion 3 on each side has a display necessary for distribution, For example, it is possible to apply a trademark, size, material, JIS mark, etc. In this respect, there is no difference from the handle of a conventional wrench, but in actual use, the following convenience is guaranteed. It will be possible.

That is, if the bolts and nuts are to be tightened or loosened at the box-end type tightening port 2A, first, the uneven shape 6A on the box-end type tightening port 2A side is first formed. If you attach your thumb and rotate the handle 1 in the specified direction, you can easily temporarily tighten or loosen the bolts and nuts. Then, this time, the uneven shape 6B on the side of the open-end type tightening opening 2B. If you attach your thumb to the handle and rotate the handle 1 again in the specified direction, you can easily tighten or loosen the bolts or nuts easily. From this point as well, you can expect great improvement in workability. In any operation, the operator can attach his / her thumb to the slip prevention concave / convex shape 6A or 6B defined by the concave groove 5 described above. Even if the surface is wet with oil or sweat, this uneven shape 6A ・ 6B By the presence of, it becomes possible to firmly and strongly grip the handle 1. Therefore, when using this combination wrench, there is no need to worry that the thumb easily slips from the surface of the display plate band and deteriorates workability as in the conventional case.

Needless to say, this is the same even when the bolts and nuts are tightened and loosened by the open end type tightening portion 2B. Even when the tightening opening 2B is used for temporary tightening or temporary loosening and the box end type tightening opening 2A is used for final tightening or final loosening, If 6A or 6B is appropriately selected, similar workability can be guaranteed.

The above-described embodiment is applied to the handle 1 of the combination wrench, but the present invention is not limited to this, and not only the handle of a double wrench or a single wrench, but also a socket wrench. Needless to say, any wrench such as a monkey wrench (including a wrench, of course) can be easily implemented and applied as long as it has a convex display plate band. Further, in the above-mentioned embodiment, the concave groove 5 defining the concave-convex shapes 6A and 6B is linearly formed by inclining it at a constant angle with respect to the longitudinal direction of the handle 1. With respect to the above, the present invention is not limited to this. For example, the concave groove 5 may be formed in a V shape, or may be formed in an arbitrary shape such as a comb tooth shape or an arrow blade shape. It is also optional to provide the desired unevenness-preventing concavo-convex shapes 6A and 6B to 4B depending on the implementation.

[0011]

[Effect of the device]

 As described above, according to the present invention, by adopting the above-mentioned configuration, as a whole, the shape of the convex display plate band similar to the conventional one still exists on both sides of the handle. It is possible to guarantee the thickness suitable for gripping or to meet the design requirements, but in reality, both side parts except the central display part left as a part necessary for display are left. Since a concave-convex shape for preventing slippage is defined by the concave groove, when using it, attach your thumb to the concave-convex shape and firmly grip the handle in a predetermined direction. Since it can be reliably rotated, there is no need to worry about the thumb slipping and reducing workability, as in the past. In addition, the presence of the central display area separates the uneven shape for slip prevention, so of these, one is used as the uneven shape for temporary tightening and the other as the concave and convex shape for final tightening. Since it can also be used, workability can be expected to be improved from this point as well, and the presence of this uneven shape can further promote the design effect.
