[0002]

2. Description of the Related Art A lateral open-type cabinet of this type has a housing having an opening at the front, a door covered by the opening, a drawer housed in the housing, and the drawer fixed inside the housing. And a latch mechanism for restricting the drawer from moving forward. A door is openably and closably attached to an opening of the housing to close a storage space formed above a bottom plate of the drawer. The drawer includes 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 in a horizontal state and pushed into the interior of the cabinet, so that a structure in which the door handle protrudes forward from the mirror surface of the door cannot be formed. Therefore, it is known that a door is opened by putting a finger on a finger insertion hole provided in the door or a 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 a finger hook protruding from the front end of the bottom plate of the drawer is used.

[0004]

However, when a finger insertion hole is formed in a door, the depth of the finger insertion hole of the door is determined by the thickness of the door. However, the internal space of the cabinet is narrowed, and the storage space cannot be used effectively.

[0005] In the case of a type in which a finger is put on the lower edge of the door to open the door, in order to pull out the drawer, the latch release knob must be slid in order to release the latch, and the puller must be pulled. It becomes degree. Further, since the latch release knob is exposed outside even when the door is closed, the latch may be released accidentally, the drawer may be pulled out, and the latch may hit the door or rattle in the housing.

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

[0007]

In order to achieve the above object, the present invention takes the following measures.

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 located 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 part of the puller, which has a finger hook on the upper surface and protrudes from the front end face of the bottom plate of the drawer, and the lower edge of the door in the closed position. Is set to a dimension that does not allow finger insertion.
Further, a latch release mechanism is provided for releasing the drawer fixed state by using the pulling operation force applied to the pull.

[0009]

With such a construction, the front end face of the bottom plate of the drawer when the door covered with the opening of the housing is closed,
Only the front end face and the door of the tab protruding there are visible, and the finger cannot be put on the tab. The door is opened by placing a finger on the gap formed between the lower edge of the door and the bottom plate of the drawer other than where the puller is located, and then pulling the drawer to pull out the drawer. , The latch is released, the drawer fixed state is released, and the drawer is pulled out. Therefore, in the closed position, the finger is not hooked on the puller, so that the latch is not accidentally released, and the drawer does not hit the door or fly back in the housing.
