Abstract

A vertically sliding manual opening and closing door with good one-handed operability, including: a plate-like door member configured to open and close an opening section by being slid vertically; a support member configured to guide the vertical sliding of the door member by a support section configured to support left and right end sections of the door member; and a lock mechanism configured to position the door member that has been raised.

Claims

1. A vertically sliding manual opening and closing door comprising:

a plate-like door member configured to open and close an opening section by being slid vertically;

a support member configured to guide the vertical sliding of the door member by a support section configured to support left and right end sections of the door member; and

a lock mechanism configured to position the door member that has been raised,

wherein the lock mechanism includes a lock member attached to an external side surface of the door member, and biased to the external side by biasing force of a biasing member,

an engaging member that is pushed in the outside direction with respect to the support member by the biasing force of the biasing member is formed on the lock member, and

a receiving member is formed on the support member such that the engaging member of the lock member is inserted into the receiving member separating from the support member towards the outside.

2. The vertically sliding manual opening and closing door according to claim 1, wherein

the lock member is formed from a flat plate, and the engaging section is an overhanging section that overhangs via a step on both left and right width direction sides.

3. The vertically sliding manual opening and closing door according to claim 2, wherein,

a cutout that acts as a handle is formed on a bottom end portion of the lock member, the cutout being recessed upwards.

4. The vertically sliding manual opening and closing door according to claim 1, wherein

the biasing member is a spring hinge with a biasing force acting in an opening direction by a spring member that is a pair of pin-linked support plates, the support plates having a rotation shaft underneath and being connected to the door member and the lock member, and being slanted such that an upper side of the lock member is positioned further to the outside than a lower side of the lock member.

5. The vertically sliding manual opening and closing door according to claim 1, wherein

the receiving section is provided with a cutout portion formed in the support member corresponding to the size of the engaging section, and a receiving member that covers the cutout portion and receives the engaging section on the outside of the support section.

6. The vertically sliding manual opening and closing door according to claim 5, wherein

with regard to the receiving section, the receiving member is larger in the vertical direction than the cutout portion formed in the support member, and the engaging section of the lock mechanism separated from the support section in the outside direction enters the receiving section from below.

7. The vertically sliding manual opening and closing door according to claim 1, wherein a lower end of the door member is an inclined end provided with a slant inclined downwards towards both the left and right ends in the width direction.
