The shaft member to be housed in the housing, the compression spring that is housed in the housing and biases the shaft member toward the upper and lower door frames, and the long holes formed in both the housing and the vertical frame, and is attached to both side surfaces of the shaft member. And a pair of operation pieces for operating the shaft member, wherein the shaft member has a projecting portion formed on the tip end surface thereof that engages with the recess of the receiving member fixed to the door frame, and is exposed on both sides of the vertical frame. Through
Its gist is that it can be moved in the axial direction against the compression spring.

The protrusion may have a conical portion at the base portion which fits the slope of the peripheral edge of the recess.

Further, the operating portion can be formed in a thin plate shape, and further, upward knurls can be formed on the surface.

According to the structure of the second invention, the door is mounted at an intermediate position between the door, the hinge for the door according to the first invention which is mounted on at least one end of the vertical frame on the hinge side of the door, and the vertical frame on the side opposite to the hinge of the door. The main point is to provide a handle.

[0010]

According to the structure of the first aspect of the invention, the shaft member having the protrusion can be moved and operated in the axial direction through the operation portion of each operation piece exposed on both sides of the vertical frame. By operating, the engagement between the recess of the receiving member and the protrusion can be released, and the door can be removed. That is, the door is
It can be removed by either operation piece on both sides of the vertical frame, and can be removed from either the indoor side or the outdoor side.

When the base of the projection of the shaft member is provided with a conical portion, the conical portion has a shape that, when the projection is inserted into the recess of the receiving member,
The recess can be fitted on the peripheral slope to correctly position the door with respect to the door frame. Further, even if the protrusion has a smaller diameter than the recess and there is a gap around the protrusion, the conical portion can be effectively prevented from rattling the door by closely contacting the slope.

Since the thin plate-shaped operating portion does not significantly project from the surface of the door, it is necessary to ensure a high level of safety for the operator even when a bather who does not wear clothes operates it. You can Further, by forming the upward knurls on the surface of the operation portion, the shaft member can be moved and operated more easily via the operation piece.
