Description

[Detailed description of the invention] The present invention relates to a sliding door shoji pulling device that pulls the shoji toward the indoor side by bundle operation.It is possible to obtain a reliable and effective shoji pulling action with a light operation. The object of the present invention is to provide a shoji pulling device for a sliding door that can improve airtightness and soundproofing between the shoji and the door frame.

The features of the present invention include: a bundle rotatably attached to the vertical stile of the shoji; an eccentric cam attached to the bundle shaft within the shoji stile so as to rotate together with the bundle;
a stopper having a cam contact surface and fixed to the inner surface of the vertical frame of the door frame in a state where the cam contact surface faces the cam surface of the eccentric cam, and when the eccentric cam integrated with the bundle rotates, The cam surface is brought into pressure contact with the cam contact surface of the abutment fitting, and the reaction force is used to move the shoji vertical stile indoors so that it comes into contact with the indoor side surface of the door frame.

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

The present invention can be applied to all types of sliding doors including sliding doors such as sliding windows, and in this embodiment, the case where the invention is applied to sliding doors will be explained as an example.

In Fig. 1, 1 is a window frame, 2 is an inner shoji, and 3 is an outer shoji. Between the vertical stile 31 of the outer shoji 3 and the vertical center of the vertical frame 11 on the left side when viewed from the indoor side of the window frame 1. The vertical stile 31 of the outer shoji 3 is equipped with a pulling device according to the present invention.
I am trying to draw it towards the inside of the room.

Normally, a pulling mechanism (not shown) is also provided between the upper and lower ends of the vertical stile 31 and the vertical frame 11, and is operated in conjunction with the pulling device of the present invention.

However, if the vertical stile 31 is highly rigid, the entire vertical stile 31 can be sufficiently pulled together using only this device.

4 is a bundle, and a bundle seat 4 is installed on the side of the outer shoji vertical stile 31.
It is rotatably attached via 1, and faces diagonally downward when pulled in, and otherwise faces vertically upward.

The bundle shaft 42 of the bundle 4 is introduced into the vertical stile 31, and the eccentric cam 5 is attached to the tip of the bundle shaft 42.
It is installed so that it can rotate together.

Reference numeral 6 denotes a stopper, which has a cam contact surface 61 and is fixed to the inner surface of the window frame vertical frame 11 in a state where the cam contact surface 61 faces the cam surface 51 of the eccentric cam 5. The rotation causes the cam surface 51 to come into pressure contact with the cam contact surface 61, and the reaction force exerts a pressing force on the eccentric cam 5 toward the indoor side.

Reference numeral 62 denotes a mounting hole for the stopper 6 to the window frame vertical frame 11, and by forming this in the shape of a vertically long hole, the mounting position of the stopper 6 can be adjusted in the vertical direction.

Further, the cam contact surface 61 of the metal fitting 6 is formed into an inclined surface that gradually approaches the indoor side toward the top as shown in the figure.

In this way, by adjusting the mounting position of the stopper 6 in the vertical direction, the horizontal distance between the center of the eccentric cam 5 and the cam contact surface 61 can be adjusted, and thereby the moving distance of the cam 5 toward the indoor side, i.e. The amount of pulling of the shoji vertical stile 31 is adjusted.

7 is a backing provided on the indoor side surface of the vertical stile 31, and 12 is a contact piece with which the backing 7 comes into contact when pulling.

Note that a rotating metal fitting 8 is fitted in the middle part of the bundle shaft 42, and the tip of the metal fitting 8 is interlocked via a long hole 91 with a slide member 9 provided in the vertical frame 31 so as to be slidable in the vertical direction. Rods 92 and 93 for interlocking the above-mentioned upper and lower pulling mechanisms are connected to both the upper and lower sides of the slide member 9.

In this way, as shown in FIGS. 7 and 8, the rotational force of the bundle 4 acts on the pulling device according to the present invention, and at the same time,
It is also transmitted to the upper and lower pulling mechanisms via the rotating metal fitting 8, the slide member 9, and the rods 92, 93.

The rotating metal fitting 8 is fitted to the bundle shaft 42 via a boss 43, and the boss 43 has a protrusion 44, and the metal fitting 8 has a protrusion 44.
4 is provided with a slot 8 that engages with a suitable circumferential play,
Due to the engagement between the protrusion 44 and the slot 8, the rotating metal fitting 8 rotates at an angle smaller than that of the bundle shaft 42.

Next, the operation of this device will be explained.

When the bundle 4 is rotated downward, the eccentric cam 5 rotates as shown in FIGS.
is pressed against the cam contact surface 61 of the cam.

Due to the pressure of the cam surface 51 against the cam contact surface 61, a pressing force is applied from the cam 5 to the fitting 6 toward the outdoor side, but since the fitting 6 is fixed to the vertical frame 11 of the window frame, the reaction force is suppressed. It is transmitted from the cam 5 to the shoji vertical stile 31 via the bundle shaft 42 and the bundle seat 41, and the vertical stile 31 is drawn toward the indoor side, and the backing 7 is brought into close contact with the contact piece 12.

In this way, airtightness, watertightness, and soundproofing between the outer shoji vertical stile 31 and the window frame vertical frame 11 are reliably maintained.

In particular, in the case of this device, in order to apply a pulling force to the outer shoji vertical stile 31 by rotation of the eccentric cam 5, a movable wedge is attached to a fixed wedge as shown in, for example, Japanese Utility Model Application No. 52-136445. Compared to a structure in which the pulling force is obtained by moving the rod vertically and sliding on an inclined surface, the resistance is much lower, and the pulling force is easy, reliable, and effective with light operation. Therefore, airtightness etc. can be significantly improved.

Furthermore, compared to the above-mentioned vertically movable wedge type, there is less wear and tear on the contact portion, and a reliable pulling action can be maintained over a long period of time.

It should be noted that the present invention can also be applied to the sliding sliding window of the above-mentioned embodiment.
