Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a main body and a cover that can be opened and closed, made of a metal plate, a wooden laminated plywood, a synthetic resin, or a composite material thereof. The present invention relates to a carrying case equipped with one or more handles.

Conventionally, the carrying case for this scale has been designed to have four corners on the bottom facing the surface with the handle, or six points including the midpoint of both long sides of the bottom, or two points on both long sides of the bottom, as shown in Figure 1. 3 sides
- (or, in addition to this, the four corners of the bottom facing the top of the lid, or in addition to this, the six points including the midpoint of both long sides of the bottom, or both long sides of the bottom) Protrusions made of metal, rubber, or synthetic resin are fixed close to the eight points divided into three equal parts, so that the bottom of the case directly contacts the ground or floor, and the impact causes damage to the stored items. This prevents the product from being affected by malfunctions, etc.

Figure 2 shows the conventional method of attaching the above protrusions, in which (a) is a metal, rubber or synthetic resin molded item, which is attached to the case body or main body with rivets or screws. It is fixed to the installed reinforcing metal fittings. (B) is a rubber or synthetic resin molded product,
It is fixed to the case body or a reinforcing metal fitting attached to the body with screws or rivets via a metal annular presser foot.

Next, Fig. 3 shows a method for corner reinforcement, in place of the above-mentioned method of fixing the metal, rubber, or synthetic resin molded body to the C case body or reinforcing metal fittings attached to the body using rivets or screws. When molding the metal fittings from a metal plate, there is a method in which protrusions corresponding to the aforementioned protrusions are formed in advance on the relevant parts of the reinforcing metal fittings, and these are fixed to each corner of the case body with screws or rivets. show.

However, although the protrusions on each model of book above have a satisfactory function in a relatively lightweight case, they may occur during handling if the contents of the case are heavy. (It has the disadvantage that it is easily damaged by m9p etc.)

I will explain this in detail for each case in Figure 2 I1.
In the case of the oral method, there are cases in which the protrusions may come off due to the impact that occurs during use. In addition, in the case of the method shown in Fig. 3, if a mild steel plate or aluminum root of around 2ml11, which is usually used as corner reinforcing metal fittings for this type of carrying case, is used, the above-mentioned protruding molded parts will be damaged by the impact during use. 1" - There are many cases where it collapses and becomes flat. Although a countermeasure to this problem is to use a metal plate that is thicker than the above, it becomes practically difficult to perform local molding as shown in FIG. In any case, the method conventionally used to protect the contents of a carrying case is that if the weight of the contents is relatively large, the method of protecting the contents of the carrying case is such that if the weight of the contents is relatively large, the object may be separated.

The goal is achieved through damage such as crushing! First, there is the problem that the contents contained in the case may be damaged.

The present invention provides a solution to the above-mentioned problems associated with conventional carrying cases.

Among these types of carrying cases, materials that are relatively heavy and have a high risk of malfunction or damage due to shocks applied to the outside of the case during handling, such as photographs, movies, etc.
Bidet 7I photography equipment, optical measurement equipment.

The purpose of the present invention is to obtain a carrying case for transporting electrical measuring instruments, computers, ceramics, arts and crafts, etc., with less damage caused by external shock.

Figure 4 shows the structure of the carrying case claimed in the claims. 1o17 is a hat-shaped metal molded body having a peripheral portion, 18
19 is a tc rubber-like elastic body molded to fit into the cap-shaped metal molded body, and 19 is attached to the cap-shaped molded body 17 by screws 20.
This is an annular holding fitting for fixing the case body 21 to the case body 21.

As shown in the figure, there are gaps a and b between the outer diameter of the cap-shaped part of the cap-shaped molded body and the inner diameter of the annular presser fitting, and between the outer wall 21 of the case body and the bottom surface of the cap-shaped molded body 17, respectively. 1
The impact generated on the bottom of the case due to the load of the case is applied to the tip of the cap-shaped molded body, and is buffered and absorbed by the deformation of the rubber elastic body. The influence on the case body and the contents can be reduced.The outer diameter of the periphery of the above-mentioned cap-shaped molded body is made larger than the inner diameter of the annular presser fitting.
And because they are all made of metal with sufficient wall thickness, they have sufficient strength to withstand shocks when handled, and can be easily separated and crushed like conventional carrying cases. do not have.

FIG. 5A shows an embodiment according to claim 1, and the donkey shows a case according to claim 2.
In place of the above-mentioned annular presser metal fitting, insert J into the corner reinforcing metal back 22.23.
：This shows the case where a cap-shaped metal molded body made of the rubber elastic body mentioned above is fixed to the main body. Abovementionedness W [Claim 1
In this case, as in the case of , the thickness of the cap-shaped metal molded body can be freely selected to maintain sufficient strength independently of the thickness of the corner reinforcing metal. This has the advantage of preventing obstacles that can easily be crushed, such as protrusions on the case.

By maintaining the above-described structure, the present invention provides a carrying case, especially one that is placed relatively heavily and has a high risk of malfunction, damage, etc. due to shocks applied to the outer surface of the case during handling. Materials, such as photography, movies, videos, etc., and optical measuring equipment.

This is effective in providing a carrying case that is less affected by external shocks and is used for transporting electrical measuring instruments, computers, ceramics, arts and crafts, etc.

[Brief explanation of the drawing]

Figure 1 shows the appearance of a conventional carrying case, and Figure 2 shows the appearance of a conventional carrying case. Figure 3 shows the structure of the main parts of a conventional carrying case.

Claims (2)

[Claims] (1) Main body and opening/closing made of metal plate, wood laminated plywood, synthetic resin, or composite materials thereof. The main body has one or more handles for carrying, and the four corners of the bottom facing the handle mounting surface, or in addition to the four corners of the bottom facing the handle mounting surface. 6 points including the midpoint of both long sides of the bottom, or 8 points dividing both long sides of the bottom into thirds, or in addition to this, the 4 corners of the bottom that cover the top of the lid, or in addition to this, the points on both long sides of the bottom. A ring-shaped metal molded body is provided with a cap-shaped metal molded body having a peripheral edge and a rubber-like elastic body that is internally fitted therein, adjacent to six points including the midpoint or eight points dividing both long sides of the bottom into three equal parts. A carrying case characterized in that a cap-shaped metal molded body having a peripheral edge that engages with the rubber-like elastic body is fixed to the main body using a presser metal fitting. (2) In the above-mentioned carrying case J5, in place of the annular presser fitting described in claim 1, a metal molded body that also serves as corner reinforcing hardware is used to provide rubber elasticity as described in claim 1.
