[0002]

2. Description of the Related Art This type of laterally open type cabinet has a housing having an opening at the front, a door fitted to the opening, a drawer accommodated in the housing, and the drawer fixed in the housing. And a latch mechanism for restricting the pulling out forward. The door is attached to the opening of the housing so as to be openable and closable so as to close the storage space formed above the bottom plate of the drawer. The drawer is composed of a bottom plate, a side plate and a back plate, and is disposed in the housing with the front end surface of the bottom plate positioned inside the opening end surface of the housing. In the case of such a cabinet, when the door is opened, the door is brought into a horizontal state and pushed into the cabinet, so that a structure in which the pull tab of the door projects forward from the mirror surface of the door cannot be formed. Therefore, it is known to open the door by putting a finger on the finger insertion hole provided on the door or the lower edge of the door.

In order to pull out the drawer, a method is employed in which the knob is slid sideways to release the latch, and then a finger hook protruding from the front end of the bottom plate of the drawer is used.

[0004]

However, when the finger insertion hole is formed in the door, the depth of the finger insertion hole of the door is determined by the thickness of the door. If the door is thickened, the clue of the handle becomes large and the finger can be easily hooked. However, the internal space of the cabinet is narrowed and the storage space cannot be used effectively.

In the case of the type in which the lower edge of the door is opened by putting a finger on the door, in order to pull out the drawer, it is necessary to slide the latch release knob to release the latch and then pull the pull handle. It becomes degree. In addition, since the latch release knob is exposed to the outside even when the door is closed, the latch may be accidentally released and the drawer may be pulled out to hit the door or rattle in the housing.

An object of the present invention is to eliminate such a problem.

[0007]

The present invention takes the following means in order to achieve such an object.

That is, the cabinet according to the present invention is of a type that can be opened by hanging a finger on the lower edge of the door, and the lower edge of the door is positioned at a height at which the front end face of the bottom plate of the drawer can be exposed to the outside. , Formed between the upper edge of the front surface of the puller that has a finger hook on the upper surface and the lower edge of the door in the closed position, so that the user can hang his / her finger on it. The gap is set to a size that does not allow the insertion of fingers.
Further, the present invention is characterized by including a latch release mechanism for releasing the drawer fixed state by utilizing the pulling operation force applied to the pull tab.

[0009]

With this structure, the front end face of the bottom plate of the drawer is closed when the door attached to the opening of the housing is closed.
The front end face and the door of the puller projecting there are only visible, and you cannot hang your fingers on the puller. To open the door, put your finger on the gap formed between the bottom edge of the door and the bottom plate of the drawer other than where the puller is located, and then pull the puller to pull out the drawer. By pulling, the latch is released, the drawer fixed state is also released, and the drawer is pulled out. Therefore, when the door is in the closed position, no finger or the like is caught on the pull tab, so that the latch is not accidentally released, and the drawer does not hit the door or rattling in the housing in an attempt to pop out.
