Description

[Detailed explanation of the idea] This invention relates to a shoji opening/closing device.

2. Description of the Related Art Conventionally, a shoji opening/closing device in which both ends of a short arm and a long arm are pivotally connected to an opening frame and a shoji frame is generally known.

However, in this type of opening/closing device, the short arm and the long arm can be pivoted at arbitrary positions, making the work cumbersome, and due to old construction techniques, the shoji does not open and close smoothly.
Furthermore, building materials have the disadvantage of not being able to absorb errors.

This invention solves the above-mentioned conventional difficulties, unitizes the opening/closing device, and forms the gap between the bracket and the short arm so that it can be adjusted at least, making it easy and accurate to install the shoji. To provide a shoji opening/closing device that does not interfere with the opening and closing of the shoji and can completely absorb assembly errors.

This invention will be described below with reference to an illustrated embodiment.A shoji 3 is provided in an opening frame 1 so as to be openable and closable via a unitized opening/closing device 2.

The opening/closing device 2 includes mounting boards 4, 4 provided on the upper frame 1a and lower frame 1b of the opening frame 1, respectively, and a bracket 5, which is fixed by a screw 18 passing through a screw hole 17 provided in the shoji 3. 5, and a short arm 6.6 and a long arm 7.7, each having one end pivotally connected to the mounting substrates 4, 4 and the other end pivotally connecting to the brackets 5, 5, respectively.

The mounting board 4 has a substantially U-shaped cross section in which the flange portion 4a on the shoji 3 side is shorter than the flange portion 4b on the opening frame 1 side, and is attached to the upper frame 1a by screws passing through the flange portion 4b.
and is removably attached to the lower frame 1b.

And the vertical frame 1clJ of the flange portion 4b! One end of a short arm 6 is pivoted to the end of I, and one end of a long arm 7 is pivoted to the end opposite to the vertical frame 1c so as to be able to swing laterally.

The other ends of the short arm 6 and the long arm 7 are each pivotally connected to a bracket 5 provided on the shoji 3.

Bracket 5, base 5a that can be attached to the horizontal stile 3a of the shoji 3
and a support part 5 that can be attached to the vertical stile 3b that is continuous to the horizontal stile 3a.
It is formed in a substantially oval shape from b.

A pin hole 8 is provided on the outside of the support portion 5b, and a pin hole 8 is provided on the outside of the support portion 5b.
A hole 9 consisting of a large diameter portion 9a and a small diameter portion 9b continuous to the large diameter portion 9a is provided at the tip of each of the holes 9.

The end of the short arm 6 is pivotally connected to the pin hole 8 of the bracket 5 configured in this manner via a pin 10, and the end of the long arm 7 is pivotally attached to the hole 9 of the bracket 5 via a pin 11. ing.

The pin 10 is composed of a base 10b provided on one side of the seat body 10ae and a tip 10c provided on the other side, and the base 10b is inserted into a hole 12 provided at the end of the short arm 7. It is inserted and its tip is caulked.

The tip portion 10c is inserted into the pin hole 8 so as to be rotatable and removable.

The distance W between the short arm 6 and the base portion 5a of the bracket 50 is such that the pin 10 can freely move up and down within the pin hole 8, so that the opening/closing device 2 can freely adjust the distance in the vertical direction.

The pin 11 is formed into a stepped cylindrical shape from a large-diameter base 11a and a small-diameter tip 11b continuous with the base 11a, and the base 11a is inserted into a hole 13 provided at the end of the long arm I. It is inserted and its tip portion is caulked with a spacer 14 made of synthetic resin or the like interposed therebetween.

Then, the tip portion 11b is inserted into the hole 9, and the long arm 7
A spacer 15 is interposed between and the bracket 5, and the tip of the tip portion 11b is caulked within the large diameter portion 9a.

At this time, a slight gap is provided between the caulked portion and the bottom of the large diameter portion 9a.

A stopper 16 is provided at a required position of the short arm 60, and this stopper contacts the mounting board 4 to restrict the range of swing of the short arm 6.

When installing such a configuration, first, the short arm 6 and the long arm T are pivoted to the bracket 5 and the mounting board 4, respectively, to form the unitized opening/closing device 2.

Next, this opening/closing device 2 is screwed to the opening frame 1 and the shoji 3, respectively.

This idea consists of the above-mentioned structure, and the shoji is installed in the opening frame so that it can be opened and closed via a unitized opening/closing device. a short arm and a long arm, each of which has a connector at a required position on the mounting board, and whose other end is pivotally connected at a required position on the bracket, and at least the short arm and the bracket. Since the shoji are formed so that the intervals can be adjusted in the vertical direction, they are easy to install and do not require special skill in construction, and the opening and closing of the shoji will not be hindered by poor construction.

Further, since the short arm and the bracket are formed so that the distance between them can be adjusted in the vertical direction, even if there are variations in the dimensions of the shoji and the opening frame, this dimensional error can be completely absorbed.

Also, a base that allows the bracket to be attached to the horizontal stile of the shoji;
If the horizontal stile is formed with a support part that can be attached to a vertical stile that is continuous with the horizontal stile, the installation becomes easy and accurate, and the connection is also strong.
