Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a spanner, and more specifically to a spanner set including metric and inch size spanners.

[Conventional technology]

A spanner or socket trench is one of the most important hand tools for tightening or loosening bolts and nuts, and a socket trench is generally a set consisting of a handle that turns the socket and multiple sockets of different sizes. Currently, socket trenches, monkey spanners, plum blossom spanners, sleeve spanners, etc. are made with metric and inch sizes as standard, and bolts and nuts also come in various metric and inch sizes, and the sizes of wrenches and spanners are indicated by socket and spanner sizes. Dimensions engraved on the main body, such as 3/4'', 20 mm, etc., indicate the size used, the diameter, and whether it is metric or inch size.

[Problem that the invention attempts to solve]

However, the distinction between metric and inch sizes is not that big; for example, 7/8″, 22mm, 3/8″
The difference between 4″ and 20mm etc. is very small, so
For this reason, when users try to use an inch size 7/8'' spanner or socket trench, they often use a 22mm metric size spanner or socket trench, but due to the hassle of socket replacement, they often use a 7/8'' size spanner. When turning bolts and nuts, I use a 22mm metric size socket instead of replacing the socket with a 7/8" socket, and even though it's a small difference, I don't have to worry about damaging the nuts or bolts or cleaning up the sockets after use. Alternatively, when you leave them for a while, it is difficult to distinguish between metric and inch sizes at a glance, so if you leave them mixed, it is very inconvenient to find the socket of the required size when you reuse it, and it is also very inconvenient to use socket trenches and spanners. From a manufacturer's point of view, there were cases in which metric and inch size sockets were mixed together due to worker carelessness during set packaging, which resulted in complaints from buyers.

Therefore, it is of primary interest to users and manufacturers of socket trenches and spanners to be able to distinguish between metric and inch sizes at a glance.

This invention was developed based on many years of experience in manufacturing socket trenches and spanners (hereinafter collectively referred to as spanners) and the opinions of users, and through repeated tests, it was possible to easily identify metric and inch sizes. The purpose of this invention is to provide a wrench that can be adjusted.

[Means to solve the problem]

In order to achieve the above object, the wrench of this invention is designed so that the difference between metric size and inch size is represented by a different color over the entire circumference of the tool every 1 to 4 tool units that require replacement. Colored line bands 11, 21, 31, 41, which are distinguished by different widths, are provided alongside numerical size indicators 13, 23, 33, 43, making it possible to distinguish between metric size and inch size at a glance.

〔Example〕

An embodiment of this invention will be described in detail with reference to FIGS. 1 to 6.

Figures 1 to 3 show the socket (sleeve), which is a tool unit that requires the replacement of the socket trench (sleeve spanner), which is a tool of this invention.
1 and 2, socket 1 has a square hole 12 of metric size, and socket 2 has a square hole 12 of inch size. At the bottom, there is a colored line band 11 around the entire circumference of the socket (tool) indicating that it is inch size, and a colored line band 22 indicating that it is metric size.
are printed in such a way that the width of the band becomes narrower depending on the socket size, that is, the size of the square fitting hole 12.

Figure 4 shows a plum blossom-shaped wrench 3, which is one of the tools, to which this invention has been applied.Similarly, along with the size numerical display 33, a colored line band 32 indicating the metric size is shown. , Fig. 5 shows a double-ended spanner 4 with this invention, which also has a numerical size display 43 and a colored line band 42 indicating the inch size in this case. be.

In any of the embodiments, it is desirable that the colored line bands for identifying metric size and inch size be printed in colors so that they can be distinguished at a glance.

[Effect of idea]

As mentioned above, this idea uses different colors to indicate the difference between metric size and inch size over the entire circumference of the tool for every 1 to 4 tool units that require replacement.
Color line belt 1 that distinguishes the size difference by the difference in belt width
Numbered size display 1, 21, 31, 41
3, 23, 33, and 43, you can clearly identify metric size and inch size tools at a glance, and the size can be identified by the width of the colored line along with the numerical display. As shown in Fig. 6, the storage position can be specified when storing in the case 5, so it can be returned quickly and accurately, which is extremely convenient, and can be carried out without adding manufacturing costs. It has the effect of

Claims (1)

[Scope of utility model registration request] For each tool unit 1 to 4 that requires replacement, colored line bands 11, 21, which distinguish the difference between metric size and inch size by different colors and the difference in size by different band widths, are provided all around the tool. A spanner characterized in that numbers 31 and 41 are provided alongside numerical size indicators 13, 23, 33, and 43.
