Description

[Detailed description of the invention] The present invention is designed to prevent the drawers from being pulled out when one of the upper and lower drawers provided in the medicine cabinet is pulled out toward the front. It is designed to be locked all at once and automatically released when it is returned to its original position, and the height of each step can be easily and quickly changed and adjusted freely without touching the locking mechanism.

The details will be explained below with reference to the embodiments shown in the drawings.

The present invention is a medicine cabinet in which a box-shaped main body 3 with a door 2 provided in a front opening 1 is provided with several slideable drawer sides 4 that are vertically spaced and drawn out to the front. The lock bar 5 is vertically movable and supported vertically, and the drawer side 4 of each stage
When the drawer side is pulled out, the engaging pieces 7 are moved upward together with the lock bar 5 to open the other drawers. It consists of a cam rail 8 that works to lock the sides and a dog 9 that is attached to the side of the lock bar 5 so as to abut or roll on the cam rail 8, and the lock bar 5 has a number of holes for attaching engagement pieces in the vertical direction. 10 is provided.

The drawer side 4 slides in the front and back direction while being guided by a fixed rail 11 that is removably attached to the main body 3 side using a locking piece 11a, etc., and the pieces 12 attached to both rear sides of the drawer side 4 are attached to the fixed rail. The tops 13 fixed to both sides of the front part of the main body are respectively fitted into the grooves 11a of No. 11 and into the recesses R4a of the side surface of the shelf to support each column and make it slidable.

The engaging piece 7 is attached to the lock bar 5 with a screw 15 via a mounting fitting 14, and the lower end is bent upward into a U-shape to form a hook portion 7.
The claw 7a' at the tip faces upward from below to the side edge of the shelf 4.

Then, the guide fitting 1 fixes the vertical part of the retaining piece 7 to the main body side.
6 is supported.

The dog 9 may be a fixed protrusion, but friction can be reduced by attaching a rotatably grooved roller to the top of the engagement piece 7 and rolling it along the cam rail 8 as shown in the example shown. motion can be transmitted smoothly.

The cam rail 8 is fixed to the lateral upper surface of each column 4 in the front-rear direction, and has a bottom portion 8a in a part of the front portion and a high portion 8b over the entire length of the rear portion thereof.

When the drawer side 4 is pushed into the normal position, the dog 9 is made to face above the lower part 8a.

When one of the drawer sides 4 is pulled out toward the front, the dog 9 is pushed up from the lower part 8a of the cam rail 8 to the higher part 8b, so that the lock par 5 also moves upward.

Therefore, when the retaining pieces 7 of each stage are moved upward, the claws 7a' are attached to the respective shelves 4.
Since it faces just in front of the engaging part 6 provided on the side, all other drawer sides are locked and cannot be pulled out forward.

The engaging portion 6 of the shelf that has already been pulled out has moved forward of the engaging piece 7 and has passed through the claw 7a', so it can freely slide back and forth.

When it is returned to its original position, the dog 9 descends again to the lower part 8a, and the lock par 5 descends together with it, releasing the lock.

When adjusting the height of the shelf 4, the fixed rail 11 is removed and fixed again at a desired position.

If the retaining piece 7 is replaced accordingly using the mounting hole 10 of the lock bar, the vertical height can be easily adjusted without changing the relationship between the locking mechanism of that stage and the locking mechanism of other stages. It turns out.

In this way, according to the present invention, if you pull out even one shelf in each tier, all the shelves in the other tiers are automatically locked and cannot be pulled out unless the previous shelf is returned to its original position. This locking mechanism can be easily implemented with a simple configuration, and it is also possible to adjust the vertical height of the shelf. It is very convenient to handle because it can be done easily and quickly without changing the locking mechanism.
