This invention relates to a pulling device for the butt part of a sliding door, such as a sliding door, which is equipped with a pair of butt shojis, and which draws the butt frames of both butt shojis toward the indoor side to maintain airtightness at the butt part. The purpose of this is to be able to automatically pull the butt stile toward the indoor side by closing the butt shoji, and this pulling action is achieved by a set of pulling mechanisms provided for one shoji. The purpose is to allow both shoji screens to be operated at the same time.

The feature of this invention is that in a sliding door equipped with a pair of butt shoji facing each other on the left and right, the upper and lower ends of the butt stile of one of the two butt shojis can be rotated around the vertical axis. A push member is provided at a position corresponding to the eccentric cam on the upper frame and lower frame of the door frame, and pushes the eccentric cam from the side to rotate when the butt shoji on which the cam is installed is closed. , a contact member that contacts the rotated eccentric cam and applies a pressing force toward the indoor direction, and a pull member that can contact the other butt stile from the outside at the outdoor end of the same butt stile. A pulling device for a butting part of a shoji in a sliding door, comprising a pulling member having two consecutively arranged pieces, and a pulling member having an inclined surface guiding the outer side plate of the butt stile of the other butt stile to the indoor side on the inside of the pulling piece. , resides in

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

The present invention is essentially applicable to all types of sliding doors (including windows) equipped with a pair of butt sliding shoji, and the following embodiments will be explained using an example in which the invention is applied to a four-panel sliding sash window. .

Reference numeral 1 denotes a window frame, which is composed of left and right (viewed from the indoor side, the same applies hereafter) vertical frames 2 and 3, an upper frame 4, and a lower frame 5. 6 and 7 are two door-stop shoji, 8 and 9 are two butt shoji that are the subject of this invention, 10 and 1
Reference numeral 1 denotes a butt frame of the two butt butt shojis 8 and 9.

Eccentric cams 12 and 13 are provided at both upper and lower ends of a right-side butt stile 11 of both shoji screens 8 and 9. Both the upper and lower eccentric cams 12, 13 are formed into approximately elliptical shapes in plan view, and their base ends are connected to the vertical shafts 14, 15 and the cam mounting frames 16, 1 with their tips facing left.
It is attached to both the upper and lower ends of the butt stile 11 via 7.

18 is an upper pushing member corresponding to the upper eccentric cam 12, and 19 is a lower pushing member corresponding to the lower eccentric cam 13, each of which is formed into a rectangular thick plate shape from plastic such as nylon (metal is also acceptable). The upper pushing member 18 is attached to the indoor side surface of a support member 20 protruding from the lower surface of the center of the window frame upper frame 4 in the window width direction, and the lower pushing member 19 is attached to the butt shoji rail 21 provided on the window frame lower frame 5. They are fixedly installed on the side surfaces of the room, with the right end faces facing the eccentric cams 12 and 13. The support member 20 is composed of a vertical portion 20a to which the upper pushing member 18 is attached and a horizontal portion 20b, and the horizontal portion 20b is attached to the lower surface of the upper frame 4 of the window frame. Furthermore, the butt shoji rail 21 also serves as a member for abutting the lower eccentric cam 13, as will be described later.

On the other hand, the butt stile 11 in the right butt shoji 9
(Hereinafter, for convenience, this will be referred to as the right side butt stile, and the butt stile 10 of the left side butt shoji 8 will be referred to as the left side butt stile). By bending it into an L shape, a pulling piece 22a facing from the outdoor side is formed on the outside plate 23 of the left side butt stile 10, and both upper and lower ends of the outside plate 22 of the right side butt stile including this pulling piece 22a are formed. Attracting members 24, 24 made of plastic or the like are fixed on the inner surface. These pulling members 24, 24 have a left side abutting frame outer plate 23 at the tip located inside the pulling piece 22a.
It has an inclined surface 24a that guides the air to the indoor side. Note that the pulling member 24 may also be provided at the middle part in the vertical direction if the shoji is long.

In this configuration, when the right side butt shoji 9 is closed with the left side butt shoji 8 closed, the tips of both the upper and lower eccentric cams 12, 13 abut the right end surfaces of the upper and lower pushing members 18, 19, respectively. Both cams 12 and 13 rotate clockwise about vertical shafts 14 and 15 in plan view. Due to this rotation, the tip of the upper eccentric cam 12 is pressed against the vertical portion 20a of the support member 20, and the tip of the lower eccentric cam 13 is pressed against the butt shoji rail 21, respectively.
The reaction force causes the right side butt stile 11 to be drawn towards the indoor side. At this time, the pulling piece 22a connected to the abutting stile 11 is attached to the outer plate 2 of the left abutting stile 10.
3 from the outdoor side and presses it, the left abutment stile 10 is also drawn toward the indoor side at the same time. In addition, vertical frames 25, 26 of double-butted shoji 8, 9
is pulled toward the indoor side by another pulling mechanism (not shown), and the upper and lower ends of the drawn shoji 8, 9 and the interior side surfaces of the window frame upper frame 4 and lower window frame as shown in FIG. Packing 27,2 provided in 5
8, airtightness between the two butt shojis 8, 9 and the window frame 1 is maintained.

By the way, the basic attracting action of this device is
As described above, this is accomplished by closing the right side butt shoji 9 with the left side butt shoji 8 closed first, but even if this procedure is reversed, the intended purpose can be achieved. That is, when the right side butt shoji 9 is closed first and the left side butt shoji 8 is closed in a state where it is pulled toward the indoor side as described above, the outer plate 23 of the shoji butt stile 10 is moved toward the drawing member 24.
It engages with the inclined surface 24a of and is pushed into the room,
As a result, it is drawn toward the indoor side of the left side butt stile 10. This action can prevent the drawing action of the left side stile 10 from being lost due to the right side butt shoji 9 being closed first by mistake.

In this way, when using this device, the shoji butt stile 1 is automatically closed by closing the butt stile 8 and 9 without requiring special operations such as handle operation.
0 and 11 can be drawn toward the indoor side. Furthermore, since the shoji drawing force is obtained by the rotation of the eccentric cams 12 and 13, the drawing action can be carried out easily and reliably. Moreover, the pulling mechanism using the eccentric cam is provided only for one shoji 9, and the pulling force of this shoji 9 is transferred to the pulling piece 22 connected to the shoji butt frame 11.
Since the information is transmitted to the other shoji 8 via the shoji 8, the structure of the device can be simplified as much as possible, and assembly can be facilitated and costs can be reduced. In addition, even if the double-butted shoji 8 and 9 are closed backwards and forwards, the pulling member 24 can ultimately achieve the same pulling state, so it is possible to prevent troubles in the pulling operation caused by erroneous operation. Furthermore, since the relationship between the closing of the shoji and its predecessor is no longer specified, it is convenient to use.

Note that the eccentric cams 12 and 13 automatically return to their original positions when the shoji 9 is opened, but in order to make the return of the eccentric cams 12 and 13 more reliable and to prevent operational troubles, certain measures are taken. both cams 12,
13 may be provided with a return spring. Taking the lower eccentric cam 13 as an example, in Figs.
Reference numeral 9 denotes a return spring, which is wound around the vertical shaft 15, with one end attached to the cam mounting frame 17 and the other end attached to the cam 13.
The eccentric cam 13 is supported by spring hooks 30 which are integrally connected to each other, and the spring 28 always applies a spring force to the eccentric cam 13 in the return direction. On the other hand, in the above embodiment, the right side butt stile 11 is equipped with a pulling mechanism using an eccentric cam, but conversely, the left side butt stile 10 may be equipped with the same pulling mechanism. In this case, it goes without saying that the pulling piece and the pulling member are provided on the left butt stile. Furthermore, the support member for the upper eccentric cam may be integrally connected to the upper frame of the window frame,
Instead of the abutting shoji rail 21, a dedicated member may be provided on the lower frame 5 as a member for abutting the lower eccentric cam.

As described above, according to the present invention, there is no need to perform a special pulling operation, and by closing the butt shoji, the shoji butt stile can be automatically pulled toward the indoor side, and moreover, The cam action allows this pulling action to be carried out easily and reliably. In addition, the pulling mechanism using the eccentric cam is provided only on one side of the butting shoji, and the pulling force acting on the butting stile of one shoji is applied to the butting stile of the other shoji through the pulling piece connected to the stile. Since both shoji screens are pulled together at the same time by transmitting information to the stile, the structure is simple, assembly is easy, costs are low, and maintenance is also advantageous. Moreover, even if the other butt shoji that does not have a pulling mechanism is later closed, the same pulling state can be obtained in the end by the pulling member provided inside the pulling piece. Therefore, it is extremely useful in practice, such as being able to prevent troubles in the pulling operation caused by erroneous operation.
