Description

[Detailed description of the invention] This invention is to adjust the amount of pulling of the shoji when pulling the shoji into close contact with the sash frame in conjunction with the rotating operation of the locking handle attached to the stile of the shoji. This relates to a pulling device that allows for

Generally, in order to press shoji such as sliding sashes or single-sliding sashes to the backing attached to the sash frame, a pulling device that is linked to the rotation of metal fittings such as crescents or locking handles is installed inside the vertical frame of the shoji. Various specific mechanisms for this type of pulling device have been proposed in the past.

By the way, if there is a distortion or slope in the opening of the building to which the sash frame is to be installed, or if there is an error in the installation of the sash frame, it may be necessary to adjust the length or height of the shoji to prevent the shoji and the sash frame from collapsing. If the distance between the sash frame and the sash frame becomes too large, the shoji may not be able to come into close contact with the backing of the sash frame at all because the pulling device cannot come into contact with the protrusions provided on the inner circumferential surface of the sash frame. Alternatively, the engagement and abutment relationship between the pulling device and the engagement protrusion may not be sufficient, and a situation may arise in which an appropriate amount of pulling is not obtained to bring the shoji and the sash frame into close contact.

Since it is not possible to maintain the airtight and watertight performance of the sash in this state, the engagement and abutment relationship between the pulling device and the projections on the sash frame must be adjusted in order to obtain the appropriate amount of shoji pulling. However, with conventional pulling devices, it is not possible to adjust the abutment and engagement relationship while the shoji is still assembled in the sash frame. Since the shoji has to be adjusted, it is not possible to reliably obtain the appropriate amount of pull at once, and the shoji has the inconvenience of having to be put on and taken off many times. Adjustment work for conventional pulling devices is not only extremely complicated and inefficient, as it requires disassembly and changing the mounting position of the pulling device itself, but it is also difficult to adjust the pulling device in high-rise buildings. This poses a problem in that the work of attaching and detaching the parts is dangerous.

Therefore, in view of these problems, the present invention aims to provide a pulling device that can easily and safely adjust the pulling amount without removing the shoji each time. It is an elaborate version.

That is, in the device of the present invention, a pulling tool equipped with an engaging head and an engaging leg is pivoted to the inner end of a stile of a shoji screen by a shaft inserted between the engaging head and the retaining leg. The pulling tool is movable in seesaw around the shaft attachment part, so that the engaging head of the pulling tool faces the indoor surface of the protrusion provided on the inner peripheral surface of the sash frame, and the engaging leg part is elastically moved toward the outdoor side. A roller provided at one end of a support that moves up and down within the shoji frame is brought into engagement contact with the outdoor side surface of the engagement leg, and the other end of the support is An interlocking rod that moves up and down inside the stile in conjunction with the rotation of a locking handle attached to the stile is inserted and removed freely, and the interlocking rod and support are screwed to the support from the indoor side. They are connected by a screw that can be operated, and the through hole for passing the tool for operating this screw is located at a position slightly shifted toward the locking handle from the position of the screw when the locking knob is in the unlocked state. It is unique in that it was built on a vertical wall with shoji screens.

The present invention will be explained below based on illustrated embodiments.
The pulling device according to the embodiment is used for a shoji of a single-sliding window for an office worker, and in particular, a drawing device installed in a sliding frame 1 as shown in FIG. 1 will be described in detail.

The illustrated fitting frame 1 is extruded as a hollow material, and a glass fitting groove 3 is formed on the surface facing the door stop frame 2, and a locking groove is formed on the indoor side of the glass fitting groove 3. A vertical wall 5 for attaching the handle 4 is provided in succession.

The pulling device is attached to the upper and lower ends of the hollow part 6 of such a joining frame 1.

Now, the pulling tool 7 according to the present invention is pivotally attached to the matching frame 1 via the housing 8 fixed in the hollow part 6 of the matching frame 1. As shown in the figure, the joining frame 1. a vertical piece 14 that abuts against the indoor side wall 13 of the vertical piece 14; and side pieces 15 that face the outdoor side of the vertical piece 14 and abut against the indoor side wall 16 of the stile 10;
The roller support shaft 18 protruding from the roller support 17 is fitted into each side piece 15, 15 at both ends, as will be described later. In addition, guide grooves 19.degree. 19 for reliably moving the roller support 17 up and down are provided over the top and bottom.

The pulling tool 20 rotatably pivoted in the housing 8 includes an engagement head 24 and an engagement leg 25 that are protruded to extend above and below the shaft attachment part A. ... protrudes from the end of the housing 12 and the end of the connecting frame 1,
Projections 2 provided on the inner surfaces of the sash lower frame 21 and the sash upper frame (not shown) located on the outside of the engaging head 240

In addition, in the illustrated embodiment, the projections 23.23a are
As for the sash lower frame 21, a rail for sliding the shoji is used, and as for the sash upper frame, an engagement protrusion formed separately is provided.

Further, the engagement leg portion 25 extends in an inclined manner toward the outdoor side from the shaft attachment portion A, and a spring 26 is interposed between the indoor side surface of the engagement leg portion 250 and the housing vertical piece 14.
is biased toward the outside of the room.

Note that the illustrated outdoor side opening of the engaging leg portion 250 is recessed so as to form a curved surface, but as will be described later, this is due to the fact that the roller 2γ that is engaged with the curved opening is pivoted. The aim is to make the vertical movement of the roller support 1γ smoother and to make the operation of the locking knob 40 rotations easier, and the weight of the knob operation can be adjusted appropriately depending on the curvature of this outdoor side opening. It can be adjusted.

As shown in FIG. 2, the roller support 17 is provided with wing pieces 30.30 that are bent and connected to face the indoor side on both sides of an outer wall 290 that is in sliding contact with the outdoor wall 16 of the joining frame A. The roller 27 is fitted between the pieces 15 and 15 on both sides of the No. The support shaft 18 of this roller 27 has both ends of the wing pieces 30 and 30.
It protrudes from the side of the housing 80 at 15°1.

, 30 are also provided with vertically elongated sliding grooves 31° 31.
When the guide rod 32, which is suspended over the
Furthermore, the roller support 17 can be moved up and down reliably.

Accordingly, as the roller support body 17 moves up and down within the pufferfish 8, the roller 2T slides on the outdoor side opening of the engaging leg portion 25 of the pulling tool 20.

The vertical movement of the roller support body 17 is performed by an interlocking rod 33 that moves up and down in conjunction with the rotation of the locking handle device. In the illustrated embodiment, the interlocking rod 33 is screwed to the roller support 1T in order to adjust the amount of pulling of the shoji.

That is, a vertical through hole 35 is formed in the connecting piece 34 fixed to the end of the roller support 17, and the tip of the interlocking rod 33 can be inserted into and removed from the through hole 35 freely.
The interlocking rod 33 is pressed and fixed within the through hole 35 by a screw 36 inserted from the side surface of the connecting piece 34.

Since the screw 36 is screwed into the vertical wall facing surface 2 of the connecting piece 34, a through hole 38 for inserting a tool 28 such as a screwdriver for operating the screw is provided as shown in FIG. The screws 36 are bored in the vertical wall 5 of the frame 1, so the screws 36 can be operated from the indoor side.

As shown in FIG. 5, this through hole 38 is bored at a position slightly shifted toward the locking handle 4, which is generally attached to the middle of the door frame 1, from the position where the screw 36 faces in the unlocked state. will be established.

That is, in the illustrated embodiment, the through hole 38 is provided at a position slightly above the position where the screw 36 faces.

Incidentally, reference numeral 9 in FIG. 5 is an inclined plate provided continuously on the connecting piece 34, and its purpose is to guide the lower end of the interlocking rod 33 to make it easier for people to pass through the through hole 38. .

The device of the present invention has the above-mentioned structure, and is attached to the upper and lower ends of the inside of the connecting frame 1, and the interlocking rod 33 connected to the roller support 17 is used for locking. As each roller 27 is pulled toward the handle, each roller 27 presses the engagement leg 25 of the pulling tool 20.

As for the structure for pulling the interlocking rod 33 toward the handle, a conventionally known means may be used, so a description thereof will be omitted here.

Simply speaking, when the locking handle 4 is rotated to perform a locking operation, the interlocking rod 33 is pulled and the upper and lower roller supports 1T are interlocked to pull up the rollers 2T, and the rollers 27 are engaged. The engaging leg portion 2 of the pulling tool 20
While sliding through the outdoor side opening at No. 5, the engaging leg portion 25 is pressed toward the indoor direction against the force of the spring 26 urging toward the outdoor direction, and the pulling tool 20 uses the shaft attachment portion A as a fulcrum. The engaging head 24 is rotated toward the outside of the room as shown by the arrow H in FIG. 4, and the stop head 240 is pressed into engagement with the rail 23, which is a protrusion facing the outside of the room.

As a result, the shoji is drawn toward the indoor side and comes into close contact with the backing P fitted into the sash frame S.

Although the drawing device has been described as being attached to the door frame 1, it goes without saying that it can also be attached inside the door stop frame 2 and provide similar effects.

Therefore, when adjusting the pulling amount using the pulling tool 20, the shoji is assembled into the sash frame S,

3 in the direction of the handle, and insert the presser screw 36 through the hole 38.
5, and then pass the screwdriver 28 into the frame 1 to loosen the presser screw 36, while inserting the screwdriver 28 into the presser screw 36, In this state, when the locking handle 28 is further turned to lock, the roller support 1T is held down by the driver 28, so the interlocking rod 33
The adjustment is completed by tightening the presser screw 36 at an appropriate point.

In this case, since the interlocking rod 33 has become longer overall, in the unlocked state, the roller 27 attached to the roller support 17 comes into contact with the engagement leg 25 at a position close to the pivoting part A of the pulling tool 20. As a result of engagement, locking...endle 4
The amount of movement of the engaging legs 25 pressed by the rising rollers 27 at the same time as the locking is rotated is not very large, and therefore the amount of pulling of the shoji by the engaging heads 24 press-engaging with the rails 23 is also small. be.

Furthermore, when the locking handle 4 is rotated in the opposite direction in the unlocking direction while the screwdriver 28 is inserted into the presser screw 36, the interlocking rod 33 descends and enters the stationary connecting piece 34. and presser screw 3 at a place deemed appropriate.
6 is tightened, the interlocking rod 33 is connected to the roller support 17 in a short state as a whole, and when the locking handle is unlocked, the roller 27 attached to the roller support is attached to the axis of the pulling tool 20. As a result of abutting and engaging with the engaging leg portion 25 at a position away from part A, the locking handle 4 is rotated and locked, and the roller 2 rises.
The engagement leg portion 25 pressed by the slider 7 moves and tilts a lot, and therefore the amount of movement of the engagement head 24 also increases and the shoji is also pulled closer.

That is, in the present invention, the tip of an interlocking rod that moves up and down in conjunction with the locking handle is screwed to a support that engages with and presses a protrusion on the sash frame and tilts the puller. When the locking handle is in the unlocked state, the screwdriver hole is drilled at a position shifted toward the handle side from the position of this screw, so the shoji can be inserted from the indoor side with the shoji still assembled in the sash frame. Therefore, it is an exceptional method that allows you to quickly, easily, reliably, and safely adjust the amount of shoji pulling without removing the shoji or disassembling the vertical stile as in the past. It has the following effects.
