Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a door stop for a sliding door (hereinafter referred to as a shoji) such as a glass door or a rain door for an opening made of aluminum sash in a building or residence.

[Problems that conventional techniques and ideas attempt to solve]

Various doorstops have been developed to stop the shoji in the middle of the opening of an aluminum sash, but they can break due to the impact of the shoji that is frequently opened and closed.
A door stop that does not function as a stopper when necessary has problems in terms of durability, has a complicated structure, and is expensive.

[Means for solving problems]

In the present invention, mounting pieces are erected on both sides of one end of a tongue-shaped substrate on which reinforcing ribs are bent, the support side plate and the contact surface are bent, and the inner peripheral end of the contact surface is attached to the end surface of the support side plate. They are assembled in contact with each other to form a box-shaped contact body, and a support piece formed continuously on the contact surface is rotatably attached to the outer surface of the mounting piece to be integrated with the board, and the board is fixed to the aluminum sash frame. It is characterized by

[Effect]

According to the above configuration, the board is attached to the lower frame of the aluminum sash at a desired position so that the rotating direction of the abutting body is perpendicular to the moving direction of the shoji, and usually the shoji is moved by folding the abutting body onto the board. It is placed on the guide groove to function as a door stop, and when the door stop is not needed, the hit body can be folded outward and removed from the guide groove of the shoji so that opening and closing of the shoji is not hindered.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view, Fig. 2 is a plan view of the contact body folded down on the board, and Fig. 3 is a sectional view of the contact body attached to the lower frame. In the figures, 1 is the board; It has a width that almost matches the bottom surface of the lower frame 2, and the mounting hole 2b formed by cutting out the guide rail 2a in the middle in the direction perpendicular to the width direction prevents the guide rail in that part from being dented by the load of the door. A reinforcing rib 3 is provided for support from below, and a fixing piece 4 for fixing is bent and formed on one side with a hole 5 for fixing. Attachment pieces 6a and 6b are bent and erected facing each other on both sides of the other end. Further, a locking square hole 7 is provided parallel to the rib 3.

Reference numeral 8 denotes a box-shaped contact body, with supporting side plates 9a and 9b bent on both sides.
Two locking protrusions 10 protrude from the lower end of a and are adapted to fit into the locking square holes 7. 11
a, 11b, and the supporting side plates 9a, 9
It is bent so that its inner circumferential surface abuts on the end face of b, and a notch 12 is provided in the middle so that it does not come into contact with the rib 3, and further support pieces 13a, 13
b is formed, and these support pieces 13a, 13b
are rotatably connected to the outer sides of the mounting pieces 6a and 6b of the base plate 1 by pins 14a and 14b, respectively, to form a door stop 15. 16a and 16b are door stop rubbers.

Reference numeral 17 denotes a fixing bracket, which has a fixing part 18 for fixing to the lower frame 2 and a fixing part 19 for fixing the fixing piece 4 of the board 1, and both the fixing part 18 and the fixing part 19 have mounting holes 20, 21 is open for each.

Next, the function of the door stop will be explained.

First, the fixing portion 18 of the bracket 17 is attached to a predetermined location on the lower frame 2 through the hole 20 with a screw. Subsequently, the fixing piece 4 of the board 1 is placed on the fixing portion 19 of the bracket 17, and the holes 5 and 21 are aligned with each other and fixed with screws. In this way the doorstop 15
is fixed to the lower frame 2.

In this fixed state, in order to perform the function of a door stop, when the stop body 8 is folded down onto the base plate 1 as shown by the solid line in FIG. is fixed. In this state, the door stop rubber 11a faces the shoji screen.

In this state, when the shoji is opened, the lower stile of the shoji hits the doorstop 15 and acts as a stopper. At this time, the contact body 8 has support pieces 13a and 1 on one side.
3b is supported by the mounting pieces 6a and 6b of the board 1, and the other side is supported by the locking protrusion 10 that fits into the locking square hole 7 of the board 1, so that it can sufficiently resist the impact of the shoji. can. Furthermore, the box-shaped contact body 8 has contact surfaces 11a, 11b on the end surfaces of the supporting side plates 9a, 9b.
By assembling the shoji in such a way that it is in contact with the shoji, deformation of the abutting body 15 can be prevented even if there is an impact from the shoji, and the substrate 1 is also prevented from being deformed by the ribs 3 and the fixing pieces 4.

Next, when the door stop is not needed, the door stop 8 is tilted outward as shown by the dotted line in FIG. 3, so that the door stop 8 does not come off the guide groove of the shoji and become a hindrance to the opening and closing of the shoji.

[Effect of idea]

According to the present invention described in detail above, a box-shaped abutment body is rotatably attached to one end of the board attached to the aluminum sash frame, and when this abutment body is tilted outward, it comes off from the guide groove of the shoji and prevents the shoji from moving. It does not interfere with opening and closing.

When the abutting body is folded down onto the board, the abutting body is positioned on the guide rail of the shoji, and the inner circumferential edge of the abutting surface of the abutting body is in contact with the end surface of the supporting side plate, and the inner circumferential edge of the abutting surface is in contact with the end surface of the supporting side plate. The doorstop has sufficient durability because it has a rigid structure that can sufficiently withstand the impact of the shoji because it comes into contact with the end surface of the substrate on which reinforcing ribs are formed.

It also has the advantage of being compact in shape, simple in structure, and easy to install.
