Description

  The present invention relates to a technical field of a crime prevention apparatus for an upward sliding sliding door that opens and closes an opening of a building.

In general, in the case of an upholstered sliding door that opens and closes an opening of a building, an anti-rest body that protrudes toward the door bottom side end of the fully closed door body is provided on the door lower frame (slider). When the steady rest is fitted loosely into the lower frame formed in the shape of a concave groove on the lower edge of the door, the door bottom side portion of the lower end of the door when fully closed is swung in and out. There is something to prevent.
By the way, in such a sliding door, there is a gap between the door bottom side end of the fully closed door and the door vertical frame, and a tool such as a bar is inserted here to force it toward the outside. When trying to open, there is a problem that the steady rest is easily damaged and can be opened.
Then, like the thing of patent document 1, it provides and reinforces the smoke return which engages like a pair between the door bottom side end surface part of a door body, and a door frame, and this aims at prevention of a crease opening. Is known.

JP 2011-231493 A

  However, even with such reinforcement, there is a gap S in the smoke return part as shown in FIG. 9, and a tool such as a bar is inserted into the gap S to try to forcefully open it with a strong force. Then, there exists a possibility that both the smoke return 6 site | part and the steadying body 8 may be damaged, the problem that it is still inferior to crime prevention remains, and the subject which this invention solves here.

The present invention has been created in view of the above-described circumstances in order to solve these problems, and the invention of claim 1 is such that a roller rolls on a suspension rail laid on a door upper frame. In the upper suspension type sliding door configured such that the door body moves left and right to open and close the opening, the door lower frame has a door bottom side relative to the door body steadying body provided on the door lower frame. It is a crime prevention apparatus for an overhanging type sliding door, characterized in that it is provided with a curl-opening prevention body that is positioned to prevent the door from being curled.
The invention according to claim 2 is characterized in that the curl-opening preventing body is provided at a position facing the door vertical frame facing the door bottom side end of the fully closed door. It is a crime prevention device of the above-mentioned hanging type sliding door.
The invention according to claim 3 is the crime prevention apparatus for an overhanging sliding door according to claim 1 or 2, characterized in that the curl-opening prevention body is long in the thickness direction of the door.

According to the first aspect of the present invention, since the curl-opening prevention body is provided at a position on the door bottom side with respect to the steady-rest body, the steady-state body can be prevented from being damaged by opening the curl and the door body. When a tool is inserted into the gap between the door frame and the door frame, an openable gap does not occur between the door frame and the door frame. I can do it.
According to the invention of claim 2, even if it is attempted to open the door body by inserting a tool into the gap between the door butt side end of the door body and the door frame, the door bottom side of the fully closed door body Since the edge-opening prevention body located at the end abuts against the door body to prevent the door body from being deformed or damaged, the door body deformation or Damage can be prevented as much as possible.
According to the invention of claim 3, the curl-opening prevention body can be closely opposed to the indoor side surface of the door body, so when trying to open the curl, the wrinkle-preventing body is in a stage before it is seriously damaged. Since the anti-peeping body comes into contact with the inside surface of the door to prevent peg opening, the steady rest can be prevented from being damaged when the peg opening action is received. Since it can be fixed by a plurality of fixing members arranged in the folding direction, a higher function for preventing folding can be exhibited.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 denotes an upper suspension door that opens and closes an opening of a building. The door 1 has a pair of left and right roller brackets 2 projecting from an upper edge thereof, The roller 2a, which is supported by the shaft, travels on the guide rail 4 provided on the upper frame 3a of the door frame 3 so as to be movable in the left-right direction, thereby changing between a fully closed position in which the opening is fully closed and a fully open position in which the opening is fully opened. Is configured to do. A self-closing device 5 for self-closing the opened door body 1 is attached to the door-end side portion (the left end side portion in FIG. 1) of the upper frame 3a. It is a closed sliding door.
The door frame 3 includes an upper frame 3a, a door end side vertical frame 3b, an intermediate vertical frame 3c, a door bottom side vertical frame 3d, and a lower frame (slider) 3e.
When the door body 1 is in the fully closed position, the door end side end abuts against the door end side vertical frame 3b, while the door bottom side end portion faces the intermediate vertical frame 3c inward and outward, and When the fully open position is reached, the door-end side end abuts on the door-end side vertical frame 3d, while the door-end side end portion faces the intermediate vertical frame 3c in the inner and outer directions.

  An end material 6 for smoke return is provided at the door end side of the door 1, and the end material 6 is U-shaped in plan view, and the outdoor leg piece 6 a is the door 1. The straddling piece 6b is in contact with the door butt side end face 1b of the door body 1, but the indoor leg piece 6c is located on the indoor side of the indoor side face 1c of the door body 1, and When the door 1 is in the fully closed state, the indoor side leg piece 6c is fitted into the fitting groove 7 provided in the intermediate vertical frame 3c in a loose-fitting manner. It is designed to prevent smoke from entering during a fire.

  An anti-swaying body (guide roller) 8 that loosely fits in a lower frame 1d in the shape of a U-shaped groove provided on the lower edge of the door 1 is located upward at a portion of the lower frame 3e that faces the intermediate vertical frame 3c. It protrudes toward the inside and prevents the shake of the lower end portion of the door 1 in the inner and outer directions. The steady rest 8 is positioned at the door end side end of the door 1 when the door 1 is fully closed.

  Further, a curl-opening prevention body 9 is fixed to the lower frame 3e via a screw 9a so as to be positioned on the door bottom side of the stabilization body 8 and adjacent to the stabilization body 8. The curl-opening prevention body 9 faces the intermediate vertical frame 3c in the indoor / outdoor direction, but in the present embodiment, the rectangular parallelepiped shape that is long in the moving direction of the door body 1 In the fully closed state, the door 1 is close to and opposed to the door end side end surface 1b. The width of the door 1 in the thickness direction of the door opening prevention body 9 is narrower than that of the steady rest 8 and is opposed to the indoor / outside surface of the door 1. The lower frame 1d is formed at such a height that it does not come into contact with the groove back surface (ceiling surface) 1e, but the fore-opening prevention body 9 of the present embodiment is against the inner and outer leg pieces of the lower frame 1d. It is configured to be separated by substantially the same distance. And, when the door opening preventing body 9 is configured in this way, when the door 1 is fully closed, the space between the indoor leg piece 6c of the end member 6 for smoke return and the indoor side surface of the fitting groove 7 is obtained. When a tool such as a bar is inserted into the gap S to forcibly open the door 1 to the outdoor side, the indoor leg 1f on the door bottom side of the door 1 abuts against the anti-opening body 9. It is designed to prevent opening up.

  In the embodiment of the present invention configured as described above, the gap S between the indoor leg piece 6c of the smoke return end member 6 and the fitting groove 7 in the fully closed state of the door 1 as described above. For example, there was an act of trying to create a space by inserting a tool such as a bar to forcefully open the door 1 to the outdoor side and pull the door butt side end of the door 1 away from the intermediate vertical frame 3c. However, the deformation of the door 1 is, at most, until the grooved indoor side leg piece 1f of the lower frame 1d of the door body abuts against the fold-off preventing body 9, and further deformation can be prevented. Opening of the door 1 to such an extent that intrudes can be avoided, and crime prevention is improved.

  Further, since the scissors opening prevention body 9 is provided on the door bottom side of the door body 1 relative to the steady rest body 8, the door body 1 becomes the scissors opening prevention body 9 by the act of opening the scissors. Even if it comes into contact, the steady rest 8 is not completely destroyed, and the function of preventing the steady rest 8 can be prevented. In addition, the curl-opening preventing body 9 is fitted in the door lower frame 1d, like the steady rest 8, so that it is not exposed to the outside and the appearance is not impaired.

  Of course, the present invention is not limited to the above-described embodiment. In the above-described first embodiment, the fold-off preventing body 9 is equidistant from both the inner and outer leg pieces of the door lower frame 1d. Although provided so as to be separated from each other, it is arranged so as to be biased toward the indoor leg piece 1f of the frame 1d under the door, like the curl-opening prevention body 10 of the second embodiment shown in FIG. Also good. In this case, a notch 10b is formed at the lower end portion of the indoor side surface 10a of the curl-opening prevention body 10 along the bent piece 1g formed at the lower end of the door body, so that the curl-opening prevention body 10 is provided as much as possible. The inner leg piece 1f can be offset and arranged. By doing so, when the door body 1 is plucked open, the indoor side leg piece 1f is prevented from being pegged when the steady rest 8 is slightly in contact with the indoor side leg piece 1f. Since it can be set to prevent further deformation by contact with the body 10, it is possible to prevent the steady body 8 from being damaged, and to obstruct the opening and closing movement of the door body 1 even after it has been subjected to the opening operation. It can be prevented.

  As a structure of the curl-opening prevention body for preventing deformation of the steady rest 8, the thickness of the curl-opening prevention body 9 may be increased in the first embodiment. As shown in the third embodiment shown in FIGS. 6, 6, and 7, the folding opening preventing body 11 may be configured to be long in the door thickness direction of the door body 1.

  Although the end material 6 for smoke return is provided in the door butt side end of the door 1 in 3rd embodiment, this end material 6 is U shape by planar view, and the outdoor side The leg piece 6 a is in contact with the outdoor side surface 1 a of the door body 1, and the straddling piece 6 b is in contact with the door butt side end face 1 b of the door body 1, but the indoor side leg piece 6 c is more than the indoor side surface 1 c of the door body 1. When the door body 1 is located on the indoor side and the door 1 is fully closed, the indoor side leg piece 6c is fitted into the fitting groove 7 provided in the intermediate vertical frame 3c in a loose fit, As a result, a combined structure prevents smoke from entering in the event of a fire.

  An anti-swaying body (guide roller) 8 that loosely fits in a lower frame 1d in the shape of a U-shaped groove provided on the lower edge of the door 1 is located upward at a portion of the lower frame 3e that faces the intermediate vertical frame 3c. It protrudes toward the inside and prevents the shake of the lower end portion of the door 1 in the inner and outer directions. The steady rest 8 is positioned at the door end side end of the door 1 when the door 1 is fully closed.

Further, a curl-opening prevention body 11 is fixed to the lower frame 3e via a screw 11a so as to be located on the door bottom side of the stabilization body 8 and adjacent to the stabilization body 8. The curl-opening prevention body 11 faces the intermediate vertical frame 3c in the indoor / outdoor direction, and a rectangular parallelepiped shape that is long in the door thickness direction of the door body 1 is a door in the fully closed state of the door body 1. The body 1 is disposed in close proximity to the door end side end surface 1b. The length of the door 1 in the thickness direction of the door opening prevention body 11 is formed to be slightly shorter than the diameter of the steady rest 8 and faces the indoor outer surface of the door 1. The body 1 is formed at a height that is not in contact with the groove back surface (ceiling surface) 1e of the lower frame 1d (substantially the same height as the steady rest body). 11 is configured to be separated from the inner and outer leg pieces of the lower frame 1d by a substantially equal distance.
In addition, a notch 11c is formed at the lower end portion of the indoor side surface 11b of the folding opening preventing body 11 along the bent piece 1g formed at the lower end portion of the door body. 11 can be arranged so as to be biased toward the indoor leg 1f side of the door 1 within a range in which the notch 11c does not contact the bent piece 1g.
Incidentally, the knot-opening prevention body 11 is required not to impair the steadying function of the steadying body 8, and therefore, close to the indoor side leg piece 1 f of the door 1 beyond the indoor side end 8 a of the steadying body 8. It is set not to face each other.

Thus, when the door opening prevention body 11 is configured, a gap between the indoor side leg piece 6c of the end member 6 for smoke return and the indoor side surface of the fitting groove 7 when the door body 1 is fully closed. When an attempt is made to forcibly open the door 1 to the outdoor side by inserting a tool such as a bar into S, the indoor leg piece 1f on the door butt side of the door 1 abuts against the anti-opening body 11. However, when such a curl-opening prevention body 11 is used, there are a plurality of the curl-opening prevention bodies 11 in the thickness direction (2 in this embodiment). Since this is fixed with the screw 11a of the book), the force to resist the opening of the knot is increased, so that higher crime prevention performance can be exhibited, and the deformation and breakage prevention functions of the door body 1 are further enhanced. I can do it.
Further, the curl-opening prevention body 11 has a rectangular parallelepiped shape that is long in the door thickness direction, so that the length in the moving direction of the door body 1 is shortened as compared with those in the first and second embodiments. As a result, the steady rest 8 can be provided close to the end of the door butt, and the curl prevention body 11 is provided closer to the door butt than the steady rest 8. However, the steadying effect of the door 1 by the steadying body 8 can be made high.

Further, as in the fourth embodiment shown in FIG. 8, the crease-opening prevention body 12 may have a rectangular parallelepiped shape close to a cube, and in this case, the thickness direction and the movement direction of the door 1 Since it is fixed with a plurality of (three in the present embodiment) screws 12a, it is possible to provide a koji-opening prevention body 12 having a greater force to resist the koji-opening, and further crime prevention. It is possible to demonstrate a high anti-folding function. In addition, also in the fold-off prevention body 12, the notch 12b is formed along the bent piece 1g, so that the indoor side surface 12c of the fold-off prevention body 12 is biased toward the indoor leg 1f side of the door body 1. It can be arranged and distributed.
In the second and following embodiments, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment. The description of the embodiment is incorporated.

  INDUSTRIAL APPLICABILITY The present invention can be used in the technical field of a crime prevention apparatus for a suspended sliding door that opens and closes an opening of a building.
