Abstract

PURPOSE:To surely actuate a device for automatically stopping a sash by automatically regulating the relation between positions of the projecting engagement streak of a lower frame and a door body relative to each other. CONSTITUTION:A longitudinal projecting engagement streak 12 formed in a sash guiding lower frame 5 in such a manner as projecting toward the outside of a room, a contact projecting piece 23 of internal angle more than 90 degrees for colliding with a longitudinal frame 3, and a stopper projecting piece 26 for projecting toward the inside of the room are provided. A sash is closed after being installed and then the contact projecting piece 23 of a turning movement body 22 which projects from a stile 17 toward the longitudinal frame 3 collides with the longitudinal frame 3 and is forcibly put in a turning movement. By the turning movement the stopper projecting piece 26 is projected toward the inside of true room and is fitted in the lower part of the projecting engagement streak of the lower frame. As a result, the relation between positions of each projecting piece 23, 26 and the projecting engagement streak relative to each other is regulated. Since the device for automatically stopping the sash can be formed simply by mounting the turning movement body to the sash directly or using small members such as fixtures, the structure of the device is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic slip-off prevention device for a shoji screen used in a building opening member, particularly an opening member that is opened and closed by sliding.

(Prior art) In order to prevent the shoji from falling off when the shoji is opened and closed, and for the purpose of crime prevention, this type of opening member is designed to keep the relative positional relationship between the upper frame or the lower frame and the shoji constant after the shoji is installed, so as to prevent the shoji from floating when the shoji is opened and closed. A locking device is used to prevent lifting from the outside.

Generally, for example, a vertically movable screw plate is placed on the top of the vertical stile of a shoji, and after the shoji is installed, it is raised and fixed within the upper frame to maximize the free space between the upper frame and the shoji. It is known that there is a method to reduce the number of rods, and as an automated version, a long movable rod is installed in the opening groove of the upper stile of the door body that receives the hanging protruding rail of the upper frame, protruding from the vertical stile. By pushing the rod rod when it collides with the vertical frame, the indoor/outdoor rotation piece that engages with it inside the upper stile is horizontally rotated to the position below the protruding rail, thereby maximizing the free space between it and the protruding rail. It is known what caused the decrease.

(Problems to be Solved by the Invention) Among these anti-removal devices, is the structure of the former simple and reliable in regulating their relative positions?On the other hand, is it necessary to raise and fix the plate after installing the shoji? This is complicated, and if this work is omitted, the purpose of the device as a stopper is lost.

On the other hand, the latter type does not require this kind of work because it is automated, and its effectiveness as a locking device is sufficiently ensured. In addition, when removing the shoji, it is necessary to pull out the movable rod, which makes the work complicated, and it accumulates inside the upper stile. There is also the possibility that the dust that has been removed may turn into koji.

The present invention was made in view of such conventional problems, and
The purpose is to provide an automatic sliding door locking device that has a simple structure, is automated in operation, and is reliable.

[Means to solve the problem]

In accordance with this object, the present invention has a longitudinal protruding engagement strip formed on the lower frame for guiding the shoji in a shape protruding toward the outdoor side, and an inner angle of 9.
It is equipped with a collision protrusion for colliding with the vertical frame of 0" or more, a retaining protrusion for protruding into the indoor side, and a rotating body pivotably supported at an intermediate position between these protrusions. The rotating body is fixed to the lower part of the shoji by having the collision protrusion protrude toward the vertical bar side from the vertical stile of the shoji and positioning the retaining protrusion below the protruding engagement wall. This article relates to an automatic sliding door locking device and its gist is C.

In the present invention, the internal angle refers to the angle between the collision protrusion piece and the retaining protrusion piece with reference to the shoji screen.

(Function) In the present invention, if the shoji is closed after being installed,
The colliding protrusion protruding from the vertical stile to the vertical frame of the rotating body collides with the vertical frame and is forcibly rotated, and due to this rotation, the retaining protrusion protrudes toward the indoor side, and the protruding engagement strip of the lower frame As a result, the relative positional relationship between the protruding engagement strip of the lower frame and the door body is automatically regulated.

〔Example〕

The present invention will be further explained below with reference to the drawings showing examples. 1 is an aluminum alloy sash, 2 is an inner and outer shoji 15.
16 is housed in a sash frame that can be opened and closed in a sliding manner; 3 is a door stop vertical frame for the outer shell 16; 5 is a lower frame; 17 and 20 are the door end stile and lower stile of the outer shell 16, respectively.

There are 2 parts between the outer frame 16 and the lower frame 5 in this satsushi l.
There are two stoppers 21 and 4o provided, one on the door edge stile 17 and the other on the middle position of the lower stile 2° in the longitudinal direction.

The stopper 21 of the door frame 17 is fixed to the lower part of the outer shell 16 by being provided at the lower end of the door frame 17.

As shown in FIGS. 5 to 7, this retainer 21 is made of hard nylon and has a rotating body 22. A rotating body 22 comprising a frame 29 made of metal has a collision protrusion 23 and a retaining protrusion 26 having an inner angle of 135° with the collision protrusion 23, and a shaft support 28 at an intermediate position. It is integrally molded through the . The collision protrusion 23 has a diameter of 12 mm in front of the tip.
It has a protruding thick-walled trapezoidal contact portion 24 having a height of 1.5 mm, and is 2.511 mm thick and 5 mm bulky, and has a length of 17 layers from the center of the shaft support 28, and
The retaining protrusion 26 has a step shape slightly lower than the upper end surface of the collision protrusion 23, and is configured in the form of a thick flat plate with a thickness of 3.5 cm, a height of 1 cm, and a length of 17 cm. Furthermore, the shaft support 28 has an impact protrusion piece 23. It has a solid cylindrical shape that matches the maximum height of the retaining protrusion 26 of 15 mm, and is provided with a vertical shaft hole at its center. Note that 25 and 27 in the figure are small protuberances protruding from the upper surfaces of the collision protrusion 23 and the retaining protrusion 26, respectively.

On the other hand, the frame 29 used in this example has a diameter of 1.2 mm.
Two stainless steel plates with a thickness of 5US304 are bent and formed into one piece by upper spout welding, and a flat and vertical face plate 30 is provided with a through hole 31 at the top. At the same time, the upper end is further bent toward the indoor side to form a small protuberance 27 of the retaining protrusion 26.
A retaining protrusion receiving plate 32 is provided with a bent piece 33 which is adapted to slightly elastically receive the contact plate, and an impact protruding piece is provided on the surface side of the surface board 30 and has its upper end bent outward in the same way. 23 small bumps 2
4, and a pair of upper and lower holding plates 36 and 37 protruding outward from the indoor end of the surface board 30. Be prepared.

The rotating body 22 has its pivot support 28 connected to a pair of retaining plates 36.
37, and is rotatably supported by a shaft 38 passing through these holding plates 36 and 37 so that an internal angle of 135'' is inwardly holding the frame 29. , between the receiving plates 32 and 34, which form an angle of 270°, the collision protrusion 23 and the retaining protrusion 26, which form an external angle of 225＠, rotate and protrude within a range of 45° each around this axis. , so that when one side is in the retracted position facing the receiving plate 32 or 34, the other side is in the protruding position at an angle of 45°.

The retainer 21 configured in this manner has the surface board 30 of the frame 29 and the retainer protrusion receiving plate 32 on two right-angled surfaces of the door frame 17 facing the door stop vertical frame 3 and the indoor side surface.
are brought into contact with each other and fixed with screws 39 through the through holes 31 from the side of the contact substrate 30.

The door frame 17 has a pair of vertical frame contact strips 1 at the tip for indoor and outdoor sections.
8 and 19 are provided in a protruding manner, or the vertical frame opposing strip 19 on the indoor side is partially cut out and removed at the lower end, and the upper stopper 21 is exposed with the two right-angled surfaces exposed. It's Toshide.

In addition, this fixing can be done by either the lower end of the collision protrusion 23 or the retaining protrusion 26 placed on the indoor side so as not to contact the protruding rail 8 for the outer shell 16 of the lower frame 5, or the protrusion protruding from the lower frame 5 on the outdoor side. This is done so that it is located lower than the longitudinally protruding engagement strip 12 formed in a shape.

That is, in one example, the protruding engagement strip 12 is located on the lower frame 5 formed by protruding rails 7.8 for the inner and outer shoji 15.16 in a stepped and parallel manner protruding toward the outdoor side. , a horizontal protrusion l protruding toward the outside from the middle vertical position of the intermediate rising wall 9
Airtight material receiving strip 1 for outer jig 16 airtight material at O tip
1 is formed to double as a lower surface wall with a width of 5 x 1 at the front and rear of the frame 1, and as a result, a groove-shaped groove along the entire length of the lower frame 5 in the longitudinal direction is formed between it and the lower frame substrate 6 with a height of about 2 cm to a little less than 2 cm. Space 13 is installed.

This retainer 21 in this example is such that if the retainer protrusion 26 protrudes toward the indoor side, it will hit the lower frame 5 and the outer retainer 16 cannot be installed inside the sash frame 2. When installing 16, it is in the dead state,
The collision projecting piece 23 is made to project toward the door stop vertical frame 3 side. If the outer shell 16 is closed in this state, the collision protrusion piece 2
3 collides with the vertical frame 3 of the doorstop, and the vertical frame opposite line 1 of the door frame 17
8 and 19, and as a result, the retaining protrusion 2
6 automatically protrudes toward the indoor side and enters the groove-like space 13, and the protruding engagement portion 12 of the bottom wall of the airtight material receiving strip 11 and the bottom frame 5 prevents the outer shell 16 from floating when traveling. This leads to prevention of lifting from the outside.

At this time, the collision projecting piece 23 is either the small protuberance 25 or the bent piece 35.
It is fitted into the recessed portion of the locking member 16 to be in a locked state, and does not come off due to vibrations caused by opening and closing of the outer lock 16, thereby ensuring a stable locking state.

In addition, in order to remove this shoji 16 from the sash frame 2, use your fingertips or a sharp tool such as a screwdriver to rotate the collision protrusion 23 that is partially exposed on the side of the door stop vertical frame 3, and the retaining protrusion will be removed. 2
6 is restored to the state before attachment of the outer shell 16, and the protruding retaining portion 1
2 restrictions will be lifted.

On the other hand, in this example, a retainer 40 at an intermediate position of the lower stile 20, which is provided together with the retainer 21, has a tongue piece 42 facing toward the indoor side protruding from a surface board 41 located on the lower surface of the lower stile 20 in a slightly stepped shape. It is a stainless steel plate with a thickness of 2 mm and a single flat shape with a tongue piece of 42 mm.
is inserted below the protruding engagement strip 12 of the lower frame 5, and thereby floats together with the retainer 21 at two locations in the opening/closing direction of the shoji 16 to prevent it from being lifted.

As described above, the retainer 40 at the intermediate position is plate-shaped and has no movable parts, so it is inserted into the notch at the center provided in the horizontal protrusion 10 of the lower frame 5. The retainer 40 is inserted and installed below the protruding engagement strip 12, and the retainer 40 is fixed to the lower stile 20 in the same manner as described above.
The lower surface is faced and fastened with two screws 43.

In addition, in the figure, 4 is a guide strip for pulling the outer shoji 16 of the vertical door frame 3, and 14 is a door stop block for the inner door 15.

Although the illustrated example has been described above, in the present invention, the protruding engagement strip can be provided separately from the airtight material receiving part, and especially in the case where the airtight structure is different from the above example. , it may be necessary to install it separately.

The protruding engagement strips are not limited to the short width planar ones as mentioned above.
It may be of any kind as long as it can be engaged with a retaining protrusion, including a hanging fin-like one.

Moreover, in the automatic detachment prevention device of the present invention.

Is a rotating body equipped with a collision protrusion and a retaining protrusion required? These must have an internal angle of 90° or more, especially an angle with a considerable protrusion of the retaining protrusion due to the collision protrusion. It is necessary to do so.

Generally, the above 135'' is considered suitable.

However, for example, if an impact part is provided at the tip of the impact protrusion that is parallel to the vertical frame of the door stop in its protruding state, this angle can be reduced to 180 degrees.
'' or more, and is not limited to a specific value.

In addition, the collision protrusion piece and the retaining protrusion piece may be connected by a connecting part extending vertically, and a shaft support may be provided at this connecting part. It can be made into a fitting shape or the like.

The rotating body can be fixed to the lower part of the shoji without using the above frame, for example, by creating a partial notch in the shaft support provided integrally with the door frame, and inserting and fixing the shaft support of the rotating body into this. It is also possible to do this directly, such as by freely pivoting, and it does not preclude the use of various intervening members that match the shape of the door frame.

As is clear from the above, in carrying out the present invention, specific materials, shapes, structures, sizes, pivot means, and The means for fixing to the shoji, the parts to be applied to the shoji, etc. can be variously changed as long as they do not go against the gist of the invention, and there is no need to limit them to what has been shown and described.

〔Effect of the invention〕

The present invention provides a longitudinally protruding engagement strip formed on a lower frame for guiding a shoji screen so as to protrude toward the outdoor side, a collision protrusion for colliding with a vertical frame with an internal angle of 90° or more, and a protrusion protruding toward the indoor side. It is equipped with protrusions to prevent the collision from coming off, and a rotating body rotatably pivoted at an intermediate position between these protrusions, so that the colliding protrusion protrudes from the vertical stile of the shoji to the vertical bar side and comes off. Since the rotating body is fixed to the lower part of the shoji by locating the stop protrusion below the protruding engagement strips, the shoji can be closed after the shoji is installed as described in the action column. The anti-removal protrusion protrudes from the inside of the room and enters below the protruding engagement strip, restricting the relative positional relationship between them and preventing the shoji from floating up and falling off while the shoji is running or being lifted from the outside. Moreover, this does not require any predetermined work or operation, and therefore, the effect of preventing the shoji from falling off can be achieved and ensured automatically at the same time as the shoji is installed.

In addition, while the present invention requires a rotating body having a protruding engagement strip of the lower frame, a collision protrusion, and a retaining protrusion, the rotating body can be connected directly or by using a small member such as a fixing metal fitting. Since it is only necessary to attach it to the shoji, the structure is simplified and simple, and it can be made at low cost.It also works reliably and prevents troubles.
Furthermore, since the operation for removing the shoji can be performed by simply rotating the collision protrusion or the retaining protrusion, this can be done extremely easily.
