JPS5834023Y2 - A box with a removable lid - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a box having a removable lid suitable for a control box or the like.

Because the installation space for control boxes mounted on vehicles, etc. is small, the open lid or door remains attached to the box body during operation with the lid or door open, or during maintenance and inspection work. In many cases, they become extremely obstructive and there is no room for the operator to enter.

In this case, if the lid can be easily removed immediately after opening, that space can be secured and used effectively for work.

There are various ways to organize the outside of the box frame, but the best way to fit the box frame for vehicles in such narrow spaces is to have the lid completely recessed into one side (front) of the box frame. When attaching and detaching the lid, there is little negative impact on other equipment installed in the surrounding area.

Conventionally, with a box frame under such conditions, the lid was tightened with externally exposed screws in several places around the surface, or as a method considering the design aspect, holes were formed in the box body to accommodate the screws. There are cases where a pin is fixed to the lid side by welding or screwing (or vice versa, a pin is fixed to the box side and a hole is made to the lid side), but the structure is complicated or pins are welded to a thin plate lid. If you do this, there will be disadvantages such as distortion of the plate and failure to install and remove it properly unless there is some play (play) in the engagement between the hole and the pin. In this case, there were problems such as vibrations becoming a source of noise.

Furthermore, with the above-mentioned screw tightening method, it goes without saying that the work of attaching and detaching the lid becomes extremely troublesome if the lid is opened and closed frequently.

The purpose of this invention is to eliminate the drawbacks of the prior art described above.
To provide a box whose lid can be easily attached and detached and whose vibration resistance is improved.

The feature of this invention is that the tip of the pin makes full use of the unique taper of the shape with rounded corners and smoothness such as rounding, and has a tightening margin without backlash (play). The above object is achieved by fitting the hook pin on the lid side with the hole on the box body side.

Of course, the same thing can be achieved even if the engagement relationship between the hole and the pin on the box body side and the lid side is completely reversed, but in the explanation of the embodiment according to the present invention, the removed lid is placed against the floor or the ground, etc. In order to prevent damage to the paint on the bottom of the lid when the lid is placed on the table, a case will be explained in which a rounded head (hook pin) with rounded corners is provided on the lid side.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 6.

FIG. 2 shows a front view of a box suitable for carrying out this invention, and shows the relationship between the box body 1 and the lid 2 attached thereto.

The box body 1 has a recessed portion into which the lid 2 is fitted flush.

Further, the lid 2 has a rectangular shape with a peripheral edge, and is used in a vertically elongated manner.

The lid 2 is fitted into the recess of the box 1 and fixed, and a locking tool 3 is provided on the upper side of the lid 2 to fix it to the box 1.

This locking tool 3 passes through the periphery of the lid 2, and the retaining pin 3A passes through the box 1 corresponding to this periphery and is moved in the vertical direction.
, a locking recess 3B formed in the locking pin 3A, and a guide tool 3C that guides the locking pin 3A only in the vertical direction;
A handle portion 3D for driving the engagement pin 3A, a locking convex portion 3E that is integrated with the handle portion 3D and locks in the locking recess 3B, a shaft 3F that supports the handle portion 3D, and a shaft 3F that supports the handle portion 3D. It consists of a spring 3G that presses the engagement pin 3A toward the box body 1,
The handle portion 3D can be operated from the front side of the lid 2 (FIG. 6).

On the other hand, on the periphery of the lower side of the lid 2, a hook pin 12 having a head formed with a taper T and a continuous roundness R is provided to protrude toward the box body 1 side.

Specifically, the hook pin through hole 1 formed on the periphery of the lid 2
The hook pin 12 is fixed by passing it through from the front side and tightening it with lock nuts 15 and 16 from the back side.

In addition, there is a hole 1 on the side of the box body 1 corresponding to this hook pin 12.
0 is provided to engage the hook pin 12.

By the way, this hole 10 is formed so that there is no play between it and the hook pin 12 in the front, rear, left and right directions.

Furthermore, although there are various methods of fixing the hook pin 12 to the lid 2 side, in the embodiment of the present invention, the gap between the box body 1 and the lid 2 is set so that the gap between the top and left and right sides is kept uniform. The piece 13 is first inserted into the hook pin 12, the hook pin 12 is passed through the hook pin passage hole 11 of the lid 2, and a flat washer 14 is inserted from the back side of the lid 2.

The spacing piece 13 is made of a non-metallic material (particularly an elastic body such as rubber) in order to eliminate metallic sounds caused by vibration.

With the structure as described above, when removing the lid 2, first lift the handle 3D of the locking tool 3 at the top of the lid to the position indicated by the two-dot chain line in FIG.

Then, the locking pin 3A moves downward and is released from the box 1.

When the top of the lid is pulled in this state, the entire lid tilts as shown in FIG.

At this time, as shown in FIG. 5, since the head of the hook pin 12 is tapered and rounded, it can move smoothly even when tilting without play with the hole 10.

In this state, lift the left and right sides of the lid 2 with both hands and remove it from the box body 1.

In addition, when attaching the lid 2, fit the hook pin 12 into the hole 10 of the box body 1 with the lid 2 tilted, and then lift the handle 3D of the locking tool 3 and attach the lid 2. Fit the whole into the recess of the box 1 so that there is no inclination, and
Let go.

By releasing the handle, the hook pin 12 is moved upward by the spring 3G and engages with the hole in the box body 1, completing the installation of the lid 2.

Incidentally, in the above embodiment, the locking tool 3 that utilizes the lever principle shown in FIG. 6 has been described, but it is not limited to the structure shown in FIG. 6.

According to the embodiment of the present invention described above, the lid can be attached and detached with simple support and operation of both hands, so operability is good.
It is particularly effective for frequently attaching and detaching the lid.

According to the present invention, a hook pin or the like is welded to the lid or box body to cause distortion in the thin plate, so that it can be easily used for vehicles and other control equipment boxes that are subject to vibration, without causing any design problems. The box can be used for items that require vibration resistance, is suitable for attaching and removing the lid in narrow spaces, and has the effect of expanding the installation range of the box.
