Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a door bag device for a folding door which is an opening member of a building.

[Prior Art] For example, the folding door known in Japanese Patent Publication No. 50-27663 is
It is said that the guide rails of the upper and lower frames or the cutouts are made at the door pocket, from which each panel can escape and be folded in order to open it.

The notch width of this guide rail needs to be not only the total folded thickness of the panel, but also the width of two or more panels in order to extend the panel and introduce it into the guide rail when closed. Become. Also, if the folded panel is moved along with the hanging stile to the door stop side, the width of the above notch will become narrower, so the hanging stile will be pivoted and fixed in place in the opening frame. There is.

[Problem to be solved by the invention] However, if the guide rail is cut out wide like this, at least the two panels on the hanging base side cannot be held by the guide rail even in the closed state, which may cause flapping due to wind pressure. .

On the other hand, in order to prevent this, the notch part of the guide rail has a first notch part with the above-mentioned predetermined width, and a second notch part, which is a steady rest insertion opening, which is cut out deeper and narrower at the edge of the notch part. At the same time, a long groove extending beyond the first notch is protruded from the two panels on the suspension side or the connecting phase between them, and this is used to extend the panel. After rotating and inserting the steady rest into the second cutout, the steady rest is slid in the opening/closing direction while the entire panel is extended, allowing the steady rest to advance into the guide rail, allowing the panel to be held in the door pocket. becomes possible. However, on the other hand, since the hanging frame is also movable in order to allow the entire panel to slide, it is not possible to fix the hanging frame in a fixed position as described above, and if the hanging frame is pulled sideways with the end panel folded. In particular, there is a possibility that the position of the steady rest may be misaligned with respect to the steady rest insertion opening, causing trouble in the introduction.

The present invention has been made in view of such problems, and provides a door bag device for a folding door that employs a movable hanging stile and can smoothly open and close the end panel on the door bag side at a fixed position. With the goal.

[Means for Solving the Problems] In accordance with the above object, the present invention was completed by separating the relationship between the rotational position of the hanging frame and the end panel.
A hanging stile that is movable in the opening and closing directions; a door pocket side end panel in which a rotating stile is rotatably connected to a joint hinge of the hanging stile;
The kick-out part provided on the end panel and protruding on the opposite side of the rotation axis, and the cut-out width of the guide rail cut-out opening for panel escape in the door pocket part, and against the kick-out part in the open state. The invention relates to a door bag device for a folding door, characterized in that it comprises a kick-out portion provided at a fixed position of an opening frame spaced apart from each other by a width of movement of a hanging base stile, and an abutting portion that can freely come into contact with each other. This is the gist.

[Function] When each panel is extended one after another from the door stop side, the end panel finally approaches the abutment part installed in the fixed position with the hanging frame still connected, and its kick-out parts are brought into contact with each other.

The collision part presses the kick-out part that protrudes on the opposite side of the rotation axis of the end panel, rotates coaxially with the end panel, applies a moment in the closing direction, and is forced into position. Make it rotate.

If the end panel is rotated to the closing angle that follows the opening/closing direction,
The kick-out portion protruding on the opposite side of the rotation axis also becomes parallel to the opening/closing direction, and releases contact with the impact portion.

When this contact is released, the end panel and the hanging stile that connect it are regulated according to the clearance between the opening frame width and the overall panel length, or the movement width of the hanging stile. If there is, it will be movable in the opening/closing direction within that width.

[Embodiments] The present invention will be further described below with reference to drawings showing embodiments. Reference numeral 1 denotes a folding door, and the folding door 1 is suspended and supported by an opening frame 2 so that it can be opened and closed.

The folding door 1 is a vertically elongated panel 4 that is made of extruded aluminum alloy material and has glass 3 installed inside.
are connected in a bellows shape by a first connecting frame 5 and a second connecting frame 6,
Furthermore, a hanging frame 7 is connected to the end of the door pocket.

That is, the vertical stile of the panel is rotatable with respect to the hinge 8 of each connecting phase 5..., 6... It is provided with a groove 11, and a U-shaped crow holding groove formed of a pair of side walls 12, 12 on each back side thereof. However, one rotating frame 9 of the door pocket side end panel 4a is the hanging frame 7.
It is rotatably connected to the joint hinge 8. Further, a thick fin-shaped kick-out part 13 made of synthetic resin is screwed to the upper end of the vertical stile (or upper stile), which is the upper part of the door compartment side end panel 4a, and is connected to the hanging stile 7. It is provided so as to protrude on the opposite side of the rotating shaft 14 of the moving frame.

The panels connected in this way are suspended and supported on the upper frame by supporting door wheels 15 fixed above each first connecting stile 5 via a rotating shaft, while horizontal door rollers 16 fixed below each
is attached to the opening frame 2 by engaging the lower frame, and thereby the first
The connecting frame 5 is always located within the plane of the opening frame and is moved to open and close during this time. The hanging stile 7 is also movably supported on the upper frame 17 by means of a supporting door wheel 15 fixed above via a rotating shaft.

Further, a horizontal door wheel 16 is provided above each second connecting stile 6, and a steady stop 18 is provided below. 18
The lower frame 19 is adapted to be engaged with the lower frame 19. However, above the second connecting frame 6 between the door pocket side end panel 4a and its adjacent panel, a steady rest 20 is provided so as to protrude relatively long northward.

The opening frame 2 is made of extruded aluminum alloy material, and is framed in a horizontally long rectangular shape, including the above-mentioned -E frame 17, a lower frame 19, and left and right end frames 21, 21, and has a door pocket portion 2 on one end frame side.
2.

The L frame 17 is provided with a first guide rail 22 in the form of a shallow groove with two grooves spaced apart from each other over its entire longitudinal length on the upper side, so that the support door wheel 16 can be supported and run. A second guide rail 24 in the form of a slightly vertically elongated groove is provided in the lower part, and this second guide rail 24 allows the horizontal door wheels 16 of each second connecting frame 6 to run, and in the case of the door pocket part 22, the rear side thereof A guide rail cutout 25 for panel escape is provided by cutting out the total length of the folding door 1 and the width 2 of the two panels. Further, an exit 26 for preventing the shaking is provided by cutting out a small width from the upper edge of the opening 25.

Here, the horizontal door rollers 16 above the ends of each panel 4 and the second connecting frame 6 are positioned within the cutout height of the guide rail cutout opening 25, while the edge on the door bag side The steady rest 20 projecting from the upper end of the panel 4a rests within the cutout height of the steady rest exit 26.

On the other hand, the lower frame 19 includes an outer fixed frame 27 and an inner U-shaped movable frame 28 having approximately the same length. 1 connection frame 5
On the other hand, by making the movable frame 28 tiltable and retractable relative to the fixed frame 27, the steady stop can be fitted into the lower guide rail 29 when the folding door l is closed. In addition, the rear fins 30 of the movable frame 28 are inserted into receiving grooves 31 provided in the steady rest 18 to hold the folding door l.

The protruding and retracting means 32 of the movable frame 28 is equipped with a pair of small door wheels 33 and 33 in the left and right directions of the movable frame 28. By pressing the engagement shaft 34 installed in the lower guide rail 29 in a blocking manner, the small door wheel 33.33 is guided to the reverse C-shaped inclined guides 36, 36 of the lock 35.35, and is movable. The frame 28 is configured to be inclined and protrude into the frame.

By the way, in the door pocket section 22 in which the guide rail cut-out opening 25 is provided in the upper frame 17, a fixed panel fixed in a fit-in manner in this example covers a portion corresponding to the folding margin 1. There are 37 locations.

This fixed panel 37 has glass 3
The upper and lower frames 17, 19 and end frames 21,
The fixing panel 37 is displaced toward the front side from the center of the fixing panel 37 and is fixed with screws to these panels.A notch 40 is provided in the upper stile 39 of this fixing panel 37, and the end of this notch is located at the end frame 21 on the door pocket side. At a predetermined position spaced apart within the movement width of the hanging frame 7, a synthetic resin block-shaped contact portion 41 can freely come into contact with a kick-out portion 13 provided to protrude from the door pocket side end panel 4a. It is provided by fixing it with screws.

By the way, if we explain the opening/closing state of such a folding door l,
When the folding door l folded into the door pocket part 22 is pulled sideways and each panel 4... is extended in order, the horizontal door wheel 16 provided above the upper end of each panel 4... and the second connecting stile 6. are sequentially introduced into the second guide rail 24 from the end of the kite rail cutout 25 of the upper frame 17. In addition, numeral 42 in the figure is a kite roller provided at the end of this guide rail cutout opening 25 for introducing the upper end of the panel. Finally, the door pocket side end panel 4a approaches the abutting part 41 installed at a fixed position while the hanging frame 7 is connected, and its kicking part is brought into contact with the abutting part 41.

If this is further pulled horizontally, the abutment part 41 is a kick-out part 1 that protrudes on the opposite side of the rotation axis 14 of the door pocket side end panel 4a.
3 and applies a moment in the closing direction to the door pocket side end panel 4a around the rotation axis 14 to force it to rotate in the fixed position, and by this rotation, the upper end of the door pocket side end panel 4a The steady rest projecting from above is inserted into the steady rest exit 26 of the upper frame 17. In addition, numeral 43 in the figure is a guide piece made of synthetic resin for introducing the swing 11, which is provided at the exit 26 for the swing rest.

When the door bag side end panel 4a rotates to the closing angle along the opening/closing direction, the kicking part 13 protruding on the opposite side of the rotation axis 14 also becomes parallel to the opening/closing direction and reaches the collision part 41. Disconnect the .

1 In this state where the contact is released, the door pocket side end panel 4a
and the hanging stile 7 that connects these are opened [using the clearance between the inner width between the left and right end frames 21, 21 of the two frames 2 and the full length width of the panel, or the movable width of the hanging stile 7. When the door pocket side end panel 4a is moved together with the hanging frame 7 in the closing direction, the relatively long steady rest 20 inserted into the steady rest entrance/exit 26 is displaced from the exit and is attached to the upper frame. It fits within 17. As a result, even when closed, the door pocket side end panel 4a located within the cutout width of the guide rail cutout 25 of the first frame 17 and the second panel 4 adjacent thereto are also rested.

In addition, from this point of view, the relatively long steady rest 20 that is inserted into the steady rest insertion opening is limited to one end panel on the side of the door bag.
It may be arranged on the second panel adjacent to this or on the upper part of the second connecting frame 6 between them, and the guide rail cutout 2
5 can also be opened in a position that corresponds to this.

Of course, the lower part of the folding door l is held by the movable frame 28 projecting from the lower frame 19 over its entire length.

2 - To open the folding door l, reverse this and release the downward hold by the movable frame 28, then open the door bag side end panel 4a.
and the second panel 4 next to it is a guide piece 4 for leading out the steady rest on the end panel 4a from the steady rest inlet/outlet 26.
4, and then fold each panel 4 in order.
... Upper end and second connecting stile 6 ... Upper horizontal door wheel 16
... is removed from the guide rail cutout 25, and the folding door l is folded. In addition, in this folding operation, the door pocket side end panel 4a is guided by the guide piece 44 for leading out, so that the collision part 41 does not impede the rotation of the kicking part 13 of the door pocket side end panel 4a.

In addition, although not shown in the drawings, the kick-out portion may be formed by integrally molding a fin of the same quality on, for example, the pivot stile or the upper stile of the door bag side end panel. If it is integrally molded into the rotating frame, one side wall on which the U-shaped glass holding groove is formed may be integrally protruded to the opposite side of the rotating shaft.For example, to improve the appearance, this can be It is also possible to form the entire length of the stile in the vertical direction, or to leave only the part facing the contact part and cut out the rest. In addition, if it is integrally molded to the upper stile, it is sufficient to extend it to the end of the side wall.

On the other hand, the collision part may be the fixed panel shown in the illustration, or alternatively a sliding door or folding door that is slid open and closed on the ilE i-1'ii side for entry and exit when the folding door is closed, for example, by means of a drop lock. In addition to being provided on a stile of a fixed object, it may also be provided on a pole that is erected at a fixed position without providing such a partition.

Generally, it is preferable for a folding door to be a top-hung type with the first connecting frame supported in a cantilevered manner, but it can also be applied to, for example, a panel-type shutter that is hung from a wire and can be folded vertically; There is no need to limit it to formal expressions.

In addition, it is possible to arbitrarily determine the installation of a plate plate in the door pocket, the configuration of the kite rail in a curved shape or an S-shape, etc., and as is clear from these points, in implementing the present invention, The specific shapes, structures, dimensions, materials, numbers, arrangement, etc. of the joint hinges, rotating frames, door pocket side end panels, kick-out parts, door pocket parts, guide rail cutouts, collision parts, etc., and the relationships among these, etc. Various changes may be made without departing from the gist of the invention.

[Effects of the Invention] Since the present invention is configured as described above, the hanging frame is movable as described in the action tank, and the end panels can be folded even when the hanging frame is not fixed. It is possible to forcibly rotate it to the closed state from the fixed position without moving it.

As a result, while the hanging frame is movable, it is possible to smoothly open and close all the way to the end panel on the door pocket side. When a steady stop is provided, it can be accurately aligned with the insertion opening of the guide rail, rotated and inserted, and then advanced further into the rail, which prevents the panel from fluttering in the door pocket. It also becomes possible.
