Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool box with a handle that is convenient to carry.

It is especially used as a tool box for automobile tools.

[Conventional technology]

Conventional tool boxes for automobile tools are made of synthetic resin, and the lock structure is generally a latching mechanism that can be opened by anyone without the need for a specific key or operation. be.

[Problem to be solved]

Toolboxes do not require a key, but conventional locking mechanisms have the following problems.

If the weight of tools increases, the latch mechanism becomes unstable.

Automotive toolboxes are expected to have strong lids that can withstand the vibrations that occur when driving outdoors, such as on mountain roads.

A structure that is easy to hold and easy to open with one hand is desired.

The object of the present invention is to provide a tool box for an automobile that has a structure that can be easily opened and closed with one hand, and that is securely locked when the lid is closed.

The opening/closing lock structure of the present invention is locked by the rotation of the handle, and its purpose is to facilitate the rotation of the handle and maintain and release the locked state.

[Means for solving problems]

The toolbox according to the present invention is characterized by the following structure.

The left and right lids, which can be opened and closed by dividing the handle in half, are provided on the container so that they can be opened and closed freely.The handle of each lid has a thin semi-cylindrical part that forms a space approximately in the center where you can put your hand. A grip is attached to the cylindrical part that slides and rotates approximately 90 degrees along the outer circumferential surface.

On the inner surface of one of the grips, a leaf spring with a semicircular side surface and a bent end is provided.

The bent end of the leaf spring moves along the outer circumferential surface of the semi-cylindrical portion on the opposite side and enters the horizontal groove provided on the outer circumferential surface to maintain the closed state of the lid.

〔Example〕

Here, one embodiment of the toolbox according to the present invention will be described based on the drawings.

FIG. 1 shows a tool box in which a left lid 2 and a right lid 3, which can be opened and closed by dividing a handle 1 in half, are attached to a container 4 with a hinge 5 so as to be openable and closable.

Each lid 2, 3 and container 4 are made of synthetic resin.

The handle portion 1 of each lid 2, 3 forms a space 6 into which a hand can be inserted approximately in the center, and has thin semi-cylindrical portions 7, 8 built thereon.

The semi-cylindrical portions 7 and 8 are configured such that their respective outer peripheral surfaces 9 and 10 have a cylindrical shape when put together.

A notch 13 is provided in the upper part of the outer circumferential surface 9 of the semi-cylindrical portion 7 for accommodating a bent end portion 12 of a leaf spring 11, which will be described later. is drilled.

On the outer peripheral surface 10 of the other semi-cylindrical portion 8, a guide groove 15 for the leaf spring 11 and a bent end portion 1 of the leaf spring 11 are provided.
A horizontal groove 16 into which the 2 is inserted is formed, and a longitudinal elongated hole 17 is bored in the center.

A grip 18 having a leaf spring 11 attached to the inner surface is attached to the outer circumferential surface 9 of one of the semi-cylindrical portions 7 so as to slide and rotate along the outer circumferential surface 9.

To attach the grip 18 and the leaf spring 11 to the semi-cylindrical part 7, insert the pin 19 into the grip hole 20,
It penetrates through the leaf spring hole 21 and further through the elongated hole 14, and is secured with a nut by sandwiching a stopper 22.

The stopper 22 is an elliptical metal plate and has a slider function that allows the pin 19 to rotate without coming off.

Incidentally, the pin 19 is relatively loosely fastened with a nut.

In other words, the semi-cylindrical portion 7 is sandwiched between the stoppers 22 so that the grip 18 can be rotated in directions Q and R in the figure without being too tight.

Similarly, a grip 28 is attached to the semi-cylindrical portion 8 as well.

By rotating the grip 18 in the Q direction, the leaf spring 11 also rotates together.

The shape of the leaf spring 11 is the outer peripheral surface 9 of the semi-cylindrical portion 7.
It is slightly curved and has a semicircular side surface with a bent end 12.

The bent end 12 of the leaf spring 11 moves in and out of the horizontal groove 16, but since it is located exactly in the space 38 between the grips 18 and 28, there is no obstruction and the movement of the bent end 12 is smooth. It will be held in

A shallow groove for storing the leaf spring 11 is provided in the outer peripheral surface 9 of the semi-cylindrical portion 7 on the side where the leaf spring 11 is provided, so that the leaf spring 11 can be stored therein.

The semi-cylindrical portion 7 and the semi-cylindrical portion 8 have a cylindrical shape as a whole when their end surfaces are aligned, but a positioning protrusion 23 is provided on each opposite end surface so that the alignment is in the normal position. A recess 24 is provided.

Therefore, the semi-cylindrical parts 7 and 8 always abut at the correct position as shown in FIG.

In this state, the lids 2 and 3 can be opened freely, and the handle 1 can also be held and carried. When locking, rotate the grips 18, 28 through an angle of about 90 degrees as shown by Q in the figure, and position the grips 18, 28 vertically as shown in FIG.

When the grips 18, 28 are in this position, the semi-cylindrical parts 7, 8 are stably joined together in a cylindrical shape without separating.

Then, the leaf spring 11 passes through the guide groove 15 and inserts its bent end 12 into the lateral groove 16, so that it is locked in this state and does not naturally move up and down.

This locked state will not be released by slight vibration or rollover, making the toolbox a stable locking mechanism.

To release the lock, rotate the grips 18, 28 as indicated by the R arrows in the figure and return them to the left and right positions.

The bent end 12 of the leaf spring 11 comes out of the lateral groove 16, passes through the guide groove 15, and fits into the notch 13.

The grips 18, 28 are in the left and right positions, the semi-cylindrical parts 7, 8 are disengaged, and the lids 2, 3 can be opened at any time.

The shapes of the grips 18 and 28 are such that when they are opposed to each other, their overall shape is a rectangular cross section with rounded corners so that they can be gripped easily and rotated without slipping.

〔effect〕

The toolbox according to the present invention has the above-mentioned configuration and has the following unique effects.

It is easy to use and does not require a key as it has a rotating handle locking mechanism.

In addition to combining the handles depending on the position of the grip, they are also latched and locked using the elasticity of the leaf spring, making the lock sturdy and able to withstand vibrations and rollovers.

The handle rotates and the group has rounded corners, making it easy to lock and release.

You can also open and close the lid by turning the grip with one hand.

The handle part is assembled with pins, and the structure is simple, there is no failure, and the manufacturing cost can be reduced.
