Description

  The present invention relates to a joinery that can escape or rescue from an exit provided in a part of the joinery even when the joinery cannot be opened due to an earthquake or the like.

Conventionally, there have been many inventions in which an emergency exit is provided at a front door, but there have been almost no examples in which an escape / rescue exit is provided on a partition door or a sliding door inside a building.
On the other hand, the present applicant has proposed a fitting with an emergency escape / rescue port that can be used for indoor fittings in Patent Document 1.
However, a manufacturing method that stably maintains the breaking strength of the exit while maintaining the design of the joinery, a method that adjusts the breaking strength according to customer requirements, a method that repairs the exit after it has been destroyed, and a low-cost manufacturing Issues such as how to do was not solved.

JP 2009-174411 A

The present invention has been made in order to solve the above-described problems, and can be manufactured with a simple structure and a stable breaking strength of the exit while maintaining the design of the joinery. An object of the present invention is to provide a fitting with an emergency escape / rescue exit that can be adjusted in strength, can be easily repaired even after the escape exit is destroyed, and can be supplied at low cost.

A closing member supported by a breakable frame is provided at a substantially lower center of the joinery, and the breakable frame is formed of a bar having a substantially U-shaped cross-section, and the closing member has a substantially U-shaped cross-section. It was made into the structure clamped by the side piece which the center groove | channel of a letter-shaped bar material opposes.
At the time of emergency escape, the closing member is removed by hitting the closing member to break the side piece of the substantially U-shaped bar having a cross-sectional shape sandwiching the closing member.

  The breaking strength of the frame can be adjusted by processing the narrow groove in the longitudinal direction on the outer side of the side groove facing the central groove of the bar having a substantially U-shaped cross section.

  The cross-sectional shape is a structure that holds a substantially U-shaped bar to a joinery body via a second frame, and the second frame is separated on the front side and the back side of the joinery, and separated By fixing one side fixed to the joinery body and making the other side detachable, the cross section of the substantially U-shaped bar and the blocking member are removed, and the damaged cross section is a substantially U-shaped bar. Was made replaceable.

An LED that emits light using a battery or a rechargeable battery as a power source is added in the vicinity of the exit so that the position of the exit can be recognized even during a power outage at night.

  Since the blocking member (specifically, a plate material fitted into the central part of the joinery) is sandwiched and fixed by a bar having a substantially U-shaped cross-section as a single part, the strength when the blocking member is broken is Since it is determined only by the material and cross-sectional shape of the material, it is easy to manufacture and the fracture strength is stable.

  Similarly, since it is a simple structure in which the closing member is sandwiched and fixed in a single part, the shape is simple, and a fitting with an exit can be provided without impairing the design.

  By processing a narrow groove on the outer surface of a bar with a substantially U-shaped cross section and adjusting the position, depth, and width of the groove, the side piece of the bar with a substantially U-shaped cross section is destroyed. The ease can be adjusted. As a result, it is possible to obtain a breaking strength according to the customer's request, or to set a direction that is easy to break (for example, it is easy to break in the direction of leaving the room and hard to break in the direction of entering the room).

  As described above, the breaking strength can be adjusted by the narrow groove, so that the dimensions of the bar having a substantially U-shaped cross section can be standardized, and the thickness of the closing member can be made constant, thereby reducing the cost. be able to.

  The second frame holding the bar with a substantially U-shaped cross-section is separated on the front and back sides of the joinery, and one side is fixed with screws etc. so that it can be attached and detached. Even if the U-shaped bar is broken, it can be easily repaired.

Since an LED emitting light using a battery or a rechargeable battery as a power source is added in the vicinity of the exit, the exit can be found even if a power failure occurs due to an earthquake occurring at night.

A perspective view of a rod having a substantially U-shaped cross section and a second frame according to the present invention. The figure which shows the force which acts on a side piece when a blocking member is pushed The figure explaining a mode that a side piece destroys when a blocking member is pushed. An example in which an H-shaped intermediate member is provided in a fitting according to the present invention

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a front view of a fitting with an emergency exit according to the present invention (a door, a sliding door, a partition, etc.), and an emergency exit 2 is provided in the lower part of the center of the joinery. The emergency exit 2 is a plate-shaped closing member. The outer periphery of the frame 3 is held by a breakable frame 4, and the outer periphery of the breakable frame 4 is held by a second frame body 7.
An LED 20 and a drive circuit 21 that emit light when the solar battery and the rechargeable battery are used as a power source are added slightly above the center of the exit.

2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is an enlarged view of a portion B in FIG.
The plate-like closing member 3 is sandwiched and held between side pieces 5b and 5b formed on both sides of a central groove 5a of a bar 5 having a substantially U-shaped cross section constituting a breakable frame 4. Yes.
An inner narrow groove 5d is provided at the boundary on the side piece 5b side of the central groove 5a of the bar 5 having a substantially U-shaped cross section.
If necessary, narrow grooves 5c are provided on the left and right outer surfaces of the bar 5 having a substantially U-shaped cross section.
There is a gap 8 between the closing member 3 and the groove bottom of the central groove 5a of the bar 5 having a substantially U-shaped cross section so that, for example, the closing member is not fixed even if the joinery body is slightly deformed. It has become.

The bar having a substantially U-shaped cross section is sandwiched between the second frames 7 and held by the joinery body.
The second frame 7 is divided into two parts on the front and back of the joinery, and is composed of a fixed side 7a and a detachable side 7b of the second frame.
The fixed side 7a of the second frame is fixed to the crosspiece 10 on the joinery body side, and the detachable side 7b is attached to the crosspiece 10 on the joinery body side or on the fixed side 7a of the second frame body, etc. It is attached using.

  FIG. 4 is a perspective view showing a state in which a bar having a substantially U-shaped cross section is sandwiched between the second frames. This figure is a corner portion of the frame, which is a portion cut at 45 °.

A state in which the closing member is detached when the closing member is hit or kicked will be described with reference to FIGS. 5 and 6.
F <b> 1 indicates a force applied to the closing member, and a part of the force F <b> 2 of F <b> 1 acts on the side piece 5 b of the bar 5 whose cross-sectional shape is fitted on the closing member 3, for example. .
Initially, the force F2 acts on the entire contact surface between the closing member 3 and the side piece 5b to bend the side piece 5b.
The location where the stress is highest due to the bending moment due to F2 is the critical section 14, and the position and length of the critical section are related to the depth of the inner narrow groove 5d and the depth of the narrow groove 5c provided on the outer surface of the bar 5. It depends on.

When F2 increases to some extent, the side piece 5b tilts as shown in FIG. 6, and when F2 exceeds a certain value, it breaks at the critical section 14.
When the side piece 5b is slightly tilted, the side piece 5b rotates with the point 13 where the corner of the second frame 7 is in contact with the side piece as a fulcrum, so that the force acting on the dangerous section is approximately proportional to F2 × (L1 / L2). To do.
Therefore, the ease of destruction of the side piece 5b can be adjusted by changing the width of the side piece, the dimensions of L1 and L2, the width of the dangerous cross section, the strength of the material, and the like.
The material of the bar 5 having a substantially U-shaped cross-section is suitable because wood is easy to process, but synthetic resin may be used.

3 and 5 and the like, the bar 5 having a substantially U-shaped cross-section is drawn symmetrically. However, depending on the customer's request and purpose of use, the left and right are asymmetrical, for example, only in the direction of leaving the room. It can be easy to destroy.
In such a case, the narrow groove 5c provided on the side piece may be processed only on one side. When there is no narrow groove 5c, the ease of destruction of the side piece 5b is substantially determined by the width of the side piece, the dimension of L1, and the strength of the material.

When it is desired to enlarge the escape port, for example, it may be convenient to divide the closing member vertically. In such a case, the H-shaped intermediate member 6 shown in FIG. 7 is fitted into the second frame 7 so as to sandwich the closing member 3.
At the time of escape, if the upper and lower closing members 3 are removed, only the thin H-shaped intermediate member 6 remains, so that the intermediate member 6 can be destroyed relatively easily.
