Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a pulling running stabilizing device at the bottom of horizontal sliding shoji. In addition, the lower part of the horizontal sliding shoji, which can maintain airtightness and is equipped with a crescent lock, is applied to horizontal sliding windows, doors, and other fittings attached to buildings that are likely to be constantly exposed to strong winds. This relates to improvements to driving stabilization devices.

[Conventional technology]

Traditionally, horizontal sliding shoji have been commonly used, which can be pulled and fixed in an airtight manner to the lower frame of the window frame, rail, or the connecting frame of the window frame by operating the handle of the crescent lock. However, in normal cases, the lower part of this type of horizontal sliding shoji is equipped with a tight member installed between the horizontal sliding shoji and the lower frame to prevent slipping at the contact part when the sliding shoji is running. The current situation is that almost no consideration is given to this.

[Problem that the invention attempts to solve]

However, in today's world, where buildings are getting taller and horizontal sliding shoji screens are also becoming relatively larger, it is difficult to install them on higher floors even though there is almost no wind on the floors near the ground. The horizontal sliding shoji part of a window or door exposed to air currents or other factors is subject to quite strong winds, and the wind pressure causes the horizontal sliding shoji to be constantly pushed toward the indoor side even when the horizontal sliding shoji is normally opened and closed. Therefore, when pulling the shoji in advance, the lower stile of the horizontal shoji hits against tight materials such as airtight materials and watertight materials that are designed to be in close contact with the shoji in order to maintain airtightness. As a result, combined with the increase in the size of the shoji itself, the frictional resistance with the tight member increases, leading to early deterioration, and the horizontal sliding shoji becomes heavier and difficult to operate. There was a problem with that.

This invention was made to solve the above problems, and its purpose is to:
In the open state of the crescent lock, which does not pull the horizontal sliding shoji, even if the horizontal sliding shoji receives wind pressure, the tight members do not collide with other members, and therefore there is no frictional resistance due to the tight members, making opening and closing operations easy. can be carried out, and
This type of horizontal extension can extend the service life of the tight member, and when the horizontal sliding shoji is pulled in and the crescent lock is in the locked state, the tight member can be pressed against other members, ensuring airtightness. An object of the present invention is to provide a pulling running stabilizing device at the lower part of a sliding shoji.

[Means for solving problems]

In order to achieve the above object, this invention fixes a tight member for maintaining airtightness and watertightness to one of the frame member and window frame member of the shoji, and this tight member is attached to the frame member and the window frame member. interpose between
Pulling at the lower part of the horizontal sliding shoji, in which the shoji is pulled together and the tight member is brought into pressure contact with the other of the stile member and the window frame member by a locking operation of a crescent lock provided on the vertical stile of the stile member. The running stabilizing device includes a rotating element within the vertical frame, which is pivotally supported on the vertical frame and engaged with the pivot of the crescent lock;
An interlocking mechanism is provided that accommodates an elevating body that is pivotally supported on the vertical frame and removably engages with the rotor, and a compression spring that biases the elevating body in the unlocking direction of the crescent lock, A movable abutting body is pivotally attached to the lower end of the vertical frame, the movable abutting body is connected to the lower end of the elevating body, and when the crescent lock is unlocked, the rotation element and the elevating body are prevented from engaging. The movable abutting body is raised by pulling down the elevating rod with the elastic force of the compression spring, and the interval is such that the movable abutting body can be restrained from being pressed against the lower frame of the window frame by the tight member. When the crescent lock is locked, the elevating body is pulled up via the rotator, the movable abutting body is brought down, and the restraint by the movable abutting body is released.

[Effect]

In other words, since the pulling traveling stabilizing device for the lower part of the horizontal sliding shoji according to this invention is constructed as described above, the movable abutting body, which is normally held upright by the biasing force of the compression spring, Since the parts are opposed to the lower frame wall part of the window frame at a predetermined interval, the pressure contact of the tight member between the frame member of the shoji and the window frame member is restrained, thereby preventing the crescent lock from being in an unlocked state. Sometimes, the shoji can be opened and closed easily and stably, and when the crescent lock is locked, the movable abutting body is lowered through the interlocking mechanism and the above-mentioned restraint is released. The shoji is pulled toward the window frame, and as a result, it is possible to press the tight member between the two, maintaining airtightness and watertightness between the shoji and the window frame. Moreover, the above operation can be performed only by locking the crescent lock.

FIG. 5 is a side view, FIG. 5 is an exploded perspective view of a part of the middle and lower portions of the vertical stile, and FIG. 6 is a perspective view of the movable abutment body.

In these Figures 3 to 6, the lower and upper parts of the vertical frames 2 of the single sliding shoji 1 are as follows:
As will be described later, lower and upper movable abutting bodies 25 and 28, which are connected to the operation of the crescent lock 3 via the interlocking mechanism 14, are arranged to be movable up and down.

The interlocking mechanism 14 is composed of the following members.

That is, the pivot shaft 7 of the crescent lock 3 is attached to the intermediate housing 16 fixed to the intermediate part of the vertical stile 2.
The rotor 17 that engages with the rotor 17 and the link plate 20 are each pivotally supported, and the upper and lower lifting rods 18 and 19 are supported so as to be slidable in the vertical direction. 17 is removably engaged with the lower lifting rod 19, the lower ends and upper ends of the upper and lower lifting rods 18, 19 are linked and engaged with both ends of the link plate 20, and the lower lifting rod 19 is A compression spring 21 constantly biases the crescent lock 3 in the unlocking direction.

Furthermore, lower and upper housings 24 and 27 are fixed to the lower and upper ends of the vertical stile 2, respectively. And, in the lower housing 24,
Guide pins 24a, 24b are made to protrude respectively, and each of these guide pins 24a, 24b
Each guide vertical hole 23 provided in the lower operating rod 23
By engaging b and 23c, the lower operating rod 23
The lower operating rod 23 is connected to the lower lifting rod 19 via a connecting rod 22. In addition, the upper housing 2
7, an upper operating rod 26 supported slidably in the vertical direction by the same means is connected to the upper elevating rod 18 via a connecting rod 15. The lifting rods 18 and 19, the connecting rods 22 and 15, and the operating rods 23 and 26 constitute upper and lower lifting bodies, respectively.

Further, each of the lower and upper movable abutting bodies 25 and 28 described above, on the other hand, has the shape shown in FIG. 6 when looking at the lower movable abutting body 25, The abutting body 25 has an intermediate portion 25a pivotably attached to the lower end of the lower housing 24, and is inserted into the lower end of the lower operating rod 23 into an operating elongated hole 25b formed on the base end side. The provided operating pin 23a is engaged, and in this state, the abutting portion 25c on the tip side is exposed between the wall surface of the lower frame 5a of the window frame 5 and the lower rail 5b. The aspect of this lower movable contact body 25 is as follows:
The same applies to the upper movable abutting body 28 which is pivotably mounted on the upper end of the upper housing 27 and engaged with the upper operating rod 26, and each of the lower and upper movable abutting bodies 25 , 28 is the interlocking mechanism 14
It is raised and lowered in conjunction with the vertical movement of the

Furthermore, either one of the facing stile and window frame 5 of the sliding shoji 4 and each stile of the single sliding shoji 1, here, as shown in FIGS. 3 and 4. On the side of the window frame 5, there is an airtight material and a watertight material that is pressed against the sliding shoji 1 when the sliding shoji 1 is pulled together with the locking of the crescent lock 3 to maintain airtightness between each side. Tight member 29 made of wood
is fixed.

Although not shown, a door roller that rolls on the lower rail 5b is arranged at the lower part of the single sliding shoji 1, as is well known.

In the case of this embodiment configured as described above, when the crescent lock 3 is unlocked and the single sliding shoji 1 is in the open state, that is, in the normal state, the sliding shoji 4 is opened as shown in FIG. A laminated stile and a window frame 5;
Each stile of the single sliding shoji 1 is spaced apart from each other at a required interval, and the interlocking mechanism 1 is moved by the elastic force of the compression spring 21.
4, each member on the lower side is urged downward, and each member on the upper side is urged upward. Therefore, the lower and upper movable abutting bodies 25 and 28 are both erected, and as for the lower movable abutting body 25, this abutting part 25c does not interfere with the free opening and closing movement of the single sliding shoji 1. It is opposed to the wall surface of the lower frame 5a with a small interval, and in this state, even if the same contact part 2
5c collides with the wall surface of the lower frame 5a, there is no risk that each surface facing the tight member 29 will come into sliding contact with the wall surface of the lower frame 5a.
The collision c is only partial and does not impede the opening/closing movement of the single sliding shoji 1.

Therefore, in this case, even if the single sliding shoji 1 receives wind pressure from the outside, when it is opened and closed,
Each stile surface of the single sliding shoji 1, especially the lower stile surface, is not brought into sliding contact with the tight member 29, which eliminates the risk of abrasion or damage to the tight member 29,
In addition, by using the single sliding shoji 1, it is possible to constantly run the sliding shoji in a stable state.

When the crescent lock 3 is operated to lock the single sliding shoji 1 in a closed state, each of the lower and upper movable abutting bodies 2
5 and 28 are both laid down, and the slight gap between the abutting portion 25c and the wall surface of the lower frame 5a, which restrains and restricts the sliding contact of the opposing surface to the tight member 29, is eliminated. , the single sliding shoji 1 is drawn toward the shoji 4 and the window frame 5 and pressed against the tight member 29, and as shown in FIG. gender is ensured.

Specifically, by operating the operating handle 8 of the crescent lock 3 in the locking direction against the elastic force of the compression spring 21, the rotor 17 is integrally rotated. 17, and in conjunction with the same operation, a series of lower lifting rods 1
9. The lower elevating body consisting of the connecting rod 22 and the lower operating rod 23 is pulled upward by a predetermined distance;
At the same time, the upper lifting rod 1 is moved through the link plate 20.
8. The upper elevating body consisting of the connecting rod 15 and the upper operating rod 26 is pulled down by a predetermined distance;
Through these operations, the lower and upper movable abutting bodies 25 and 28 are both lowered toward the lower rail 5b and the upper rail, thereby releasing the restraint on the tight member 29 and restoring its function. .

Furthermore, when the crescent lock 3 is unlocked, the engagement between the rotator 17 and the lower lifting rod 19 is released, and the restoring force of the compression spring 21 causes each member of the interlocking mechanism 14 to return to its original position. Each movable contact body 2 of
5, 28 can be erected again and returned to the state shown in FIG. In conjunction with the operation of the operating handle 8 of the lock 3, it can be operated as expected.

In the above embodiments, the lower and upper movable contact bodies are made of hard synthetic resin such as nylon, and are integrated with other parts, or are made of hard synthetic resin as a whole. Made of resin,
Alternatively, it is of course possible to use a light metal, and use a roller as the abutting part, so that the abutting part can roll directly and freely abut against the wall surface of the lower frame part.

Further, in the above embodiment, a single sliding shoji among the horizontal sliding shoji was explained, but the present invention can also be applied to various types of similar types of shoji.

[Effect of idea]

As detailed above, when using this idea,
A tight member for maintaining airtightness and watertightness is fixed to one of the frame member and the window frame member of the shoji, and this tight member is interposed between the frame member and the window frame member, and the vertical of the frame member A pulling traveling stabilizing device in a lower part of a horizontal sliding shoji, which pulls the shoji and presses the tight member against the other of the stile member and the window frame member by locking a crescent lock provided on the stile. and a rotating element pivotally supported in the vertical frame and engaged with the pivot of the crescent lock, and a rotating element pivotally supported in the vertical frame and removably engaged with the rotating element. An interlocking mechanism is provided that accommodates an elevating body and a compression spring that urges the elevating body in the unlocking direction of the crescent lock, and a movable abutting body is pivotally attached to the lower end of the vertical frame. A body is connected to the lower end of the elevating body, and when the crescent lock is unlocked, the rotation element is disengaged from the elevating body, and the elevating rod is pulled down by the elastic force of the compression spring to move the movable abutting body. The movable abutting body is raised and lowered via the rotator in conjunction with the locking operation of the crescent lock. Since the movable abutting body is laid down by pulling up the body to release the restraint by the movable abutting body, the following effects can be obtained.

That is, the movable abutting body, which is normally held upright by the biasing force of the compression spring, is opposed to the lower frame of the window frame at a predetermined interval. In the normal state when the crescent lock is unlocked, the tight member fixed to the crescent lock is restrained from being pressed against the other side, and the tight member is not pressed against the other side.
The opening and closing operation of the shoji can be done easily, stably and lightly. At the same time, it is possible to avoid unnecessary wear and damage to the tight members. In addition, this normal maintenance is achieved by the connection between the crescent lock and the elevating body. It is certain that this is done only by the elastic force of the compression spring.

Furthermore, when the crescent lock is locked, this operation causes the movable abutting body to fall down and release the restraint via the interlocking mechanism, so the shoji is pulled toward the window frame, and as a result, the shoji is pulled toward the window frame. It becomes possible to press the tight member between these two, and it is possible to effectively maintain airtightness and watertightness between the shoji and the window frame.

Furthermore, this operation has various practical effects such as the operation itself being extremely simple and easy, since it is sufficient to simply lock the crescent lock.
