DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing a sash or door having a sliding structure or a sliding structure from colliding with a human body. That is, the present invention relates to a device for preventing a body such as a limb or a head from being injured by sliding movement of a sash or a door.

[0002]

2. Description of the Related Art In general houses, offices and other buildings, sashes sometimes collide with other people's limbs or heads due to careless operation of a sash having a sliding structure. . Also, in a van-structured automobile, a slide-structured door may collide with a part of the body and cause injury.

The technical problem of the present invention is to pay attention to such a problem and to detect that a sash or a door of a sliding structure has come into contact with a body to prevent a collision from occurring.

[0004]

The technical problem of the present invention is solved by the following means. The collision prevention structure according to claim 1 includes a vertical frame portion of a sash of a slide structure, a detector comprising a conductive rubber whose electric resistance is reduced when compressed, and electrodes provided on both sides of the conductive rubber. It is attached.

[0005] A power supply and an actuator are connected to both electrodes of the detector, and a braking means driven by the actuator causes a lower frame and a window frame of a sash to be driven by a detection signal of the detector. It has a structure that fits between the lower frame and applies braking force to sashes.

Thus, the electrodes on both sides of the conductive rubber are
Since the actuator for driving the brake is connected,
When a human finger or a part of the human body comes into contact with the outer electrode, the conductive rubber is compressed and the electric resistance is reduced, so that power is supplied to the actuator and the actuator operates.

As a result, the braking means fits between the lower frame of the sash and the lower frame of the window frame to apply a braking force to the sash.
The sash becomes immovable anymore, and it is possible to prevent an accident such as an injury due to impact force acting on a human body such as a finger.

According to a second aspect, in the vertical frame portion of the sash having a slide structure, a pair of vertically long electrodes are opposed to each other in a non-contact state, and the outer electrodes are easily deformed when subjected to pressure. A detector that is in electrical contact with the fixed electrode on the side of the vertical frame portion is attached.

[0009] A power supply and an actuator are connected to the pair of electrodes, and a braking means driven by the actuator moves a lower frame of the sash and a lower frame of the window frame according to a detection signal of the detector. To provide a braking force to the sashes.

A second aspect of the present invention differs from the first aspect in the structure of the detector. In this case, when a human body such as a finger comes into contact with an electrode outside the vertical frame portion of the sashes, the detector contacts the fixed electrode by the force. Power is supplied to the actuator and the actuator is activated to apply a braking force to the sashes, so that it is possible to prevent the sashes from moving further and applying an impact to the human body. .

It should be noted that the "sashes of a sliding structure" in the present invention are not limited to sashes of buildings such as houses, but also include, for example, doors of a sliding structure of an automobile such as a one-box type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of how the structure for preventing collision of sashes of a slide structure according to the present invention is practically embodied will be described. FIG. 1 is a view showing a first embodiment of a structure for preventing collision of a slide structure sash according to the present invention.

Reference numeral 1 denotes a window frame of a building, which includes an upper frame 1a, a right vertical frame 1b, and a lower frame 1c. Reference numeral 2 denotes a sash having a slide structure, and includes an upper frame 2a, a right vertical frame 2b, and a lower frame 2.
c is shown. The vertical frame on the left side of both the window frame 1 and the sash 2 is not shown.

A detector 3 is attached to the vertical frame 2b of the sash 2 at a position facing the vertical window frame 1b. The detector 3 has a structure in which a conductive rubber 3c whose electrical resistance decreases when compressed is sandwiched and fixed between a pair of electrodes 3a and 3b.

The electrode 3a on the side of the vertical frame portion 2b of the sash is called an inner electrode or a fixed electrode, and the electrode 3b on the side of the vertical window frame 1b is called an outer electrode or a deformable electrode. When the finger 4 or other body touches the outer electrode 3b, the pressure causes the electrode 3b
Easily deforms, and the conductive rubber 3c is compressed and retracted.

Therefore, the inner electrode 3a may be a rigid body, but the outer electrode 3b must be easily deformable, for example, by vapor deposition of a conductor material. For example, a foil or film of aluminum or the like may be used.

The conductive rubber 3c is a material whose electric resistance is reduced when compressed by a method such as mixing a powder of a conductor into rubber, or the like. Conduction is made between the electrodes 3a and 3b on both sides, and the switch is turned on. In this way, when the electrodes 3a and 3b are brought into conduction, the sash 2 comes into contact with the body and the like,
Functions as a detector.

The electrodes 3a and 3b are connected by wires 19 to
The power supply 5 and the actuator 6 are connected. As shown in FIG. 2, the actuator 6 has an iron core 8 inserted in the center space of the electromagnetic coil 7, and a wedge-shaped brake 9 is connected to the iron core 8 via a strong coil spring 10. I have.

Since the upper end of the brake 9 is supported by the brake unit plate 6a or the sash frame 2b via the support shaft 11, when the electromagnetic coil 7 is energized, the iron core 8 is attracted and the brake 9 Is sandwiched between the window frame and the lower frames 1c and 2c of the sash, and the sash 2 cannot be moved to the right. As a result, the conductive rubber 3c is
Although it may be depressed, it can be prevented from moving further and giving an impact to the human body.

A wedge-shaped portion 9a is provided at the lower end of the sash lower frame 2c.
If the inclination 2s is set to the same level as above, the braking action works more reliably. Also, covering the wedge-shaped portion 9a with a non-slip material such as rubber is effective for improving the braking action.

When the human body such as the finger 4 separates from the sash frame side, the conductive rubber 3c between the electrodes 3a and 3b is restored to the original state, and the electric resistance is increased. Iron core 8 returns to its original state.

At this time, a relatively weak return spring 12 is provided to ensure that the brake 9 is easily returned to its original position. Therefore, the wedge-shaped portion 9a is separated from between the sash lower frame 2c and the lower window frame 1c. The braking action is released. Spring 12
Alternatively, a permanent magnet may be provided, and the magnet may be returned using a magnetic repulsive force.

FIG. 3 is a view showing a second embodiment of the present invention. The structure of the detector is different from that of the embodiment shown in FIG. In this detector 13, the fixed electrode 13a and the deformable electrode 13b face each other in a non-contact state. In this embodiment, the electrode 13a attached to the vertical frame portion 2b of the sash 2 may be rigid, but the outer deformable electrode 13b is easily deformed when the finger 4 or the like comes into contact, and the inner fixed electrode 13a It has a structure that comes into contact with.

FIGS. 4A and 4B show details of the deformable electrode 13b. FIG. 4A is a top view and FIG. 4B is a side view as seen from the right side. The deformable electrode 13b is vertically long along the vertical frame 2b of the sash 2, but has a semi-cylindrical shape when viewed from above. In this semi-cylindrical portion, a number of slits 13s are formed in a comb shape.

Then, the portion where the slit 13s is not formed is formed via the insulator spacer 14 and the fixed electrode 13a.
The sash is fixed to the vertical frame portion 2b. Therefore, when the finger 4 or the like comes into contact with the semi-cylindrical deformable electrode 13b, the semi-cylindrical portion 13b is easily deformed, and the tip of the semi-cylindrical portion 13b comes into contact with the inside fixed electrode 13a, and is electrically connected to the switch. Take on.

As a result, as described with reference to FIG. 2, the electromagnetic coil 7 of the actuator 6 is energized to move the brake 9 toward the electromagnetic coil 7, and the wedge-shaped portion 9a is moved to the window frame and the lower frames 1c, 2c of the sash. The sash 2 cannot be moved by being interposed therebetween. Therefore, it is possible to prevent a strong impact force from acting on a human body such as a finger.

When the human body separates from the semi-cylindrical deformable electrode 13b, it is restored to its original state by the spring force of the semi-cylindrical part, separates from the inner electrode 13a and is turned off, and the wedge-shaped part 9a is turned off. By the force of the return spring 12, the lower frame 1c and 2c are separated from each other, and the sash can move freely.

FIG. 5 shows another embodiment of a detector having a variable electrode structure, in which a large number of slits 16 are formed in both sides 15a, 15b of a thin metal band 15c having a U-shaped cross section. I have. Therefore, it becomes a centrifugal deformable electrode 15 as a whole. On the fixed electrode 13a, an insulator 17 that is easily elastically deformed, such as a sponge, is attached, and the above-mentioned deformable electrode 15 is put thereon and adhered thereon.

Normally, centipede-shaped feet 15a, 15b
Does not come into contact with the fixed electrode 13a, but when a finger or the like comes into contact with the thin metal band 15c, it is easily pushed in and deformed, and the feet 15a and 15b on both sides come into contact with the fixed electrode 13a, and the switch is turned on. Become.

As shown by the dashed line in FIG. 5A, if the feet 15a and 15b are formed in a shape of a letter "C", if the human body comes into contact with the thin metal band 15c and becomes concave, Since the leg-shaped legs 15a and 15b are elastically deformed and spread, no impact force acts on the human body even after the switch is turned on.

The deformable electrodes 3b, 13b and the thin metal band 15c are insulated, for example, by applying an insulating tape to the deformable electrodes 3b, 13b and the thin metal band 15c so that the deformable electrodes 3b, 13b and the thin metal band 15c do not come into direct contact with the human body. Good to put.

The deformable electrodes 13b and 15 are formed in a comb shape by forming a slit. It is possible to realize a detector that is easily deformed and brought into contact with the fixed electrode side and is turned on.

Both the conductive rubber type detector shown in FIG. 1 and the detector composed of the comb-shaped electrodes 13b and 15 shown in FIGS. 3 to 5 can be mounted from the upper end to the lower end of the vertical frame portion 2b of the sash. No matter which part of the sash vertical frame portion 2b comes in contact with the human body, the braking force acts on the sash reliably, and the sash can be stopped.

The fixed electrodes 3a and 13a can also be used as the vertical frame portion 2b of the sash, but as shown in FIGS. 4 and 5, an insulating layer 18 is provided on the vertical frame portion 2b, and the fixed electrode 3
a, 13a may be laminated.

The above is an example in which the present invention is applied to a sash of a building. However, the present invention can be applied to a sliding door of a one-box type automobile or the like, for example.
The "sliding structure sashes" in the present invention include "a sliding structure door of an automobile or the like".

[0036]

According to the first aspect, since the actuator for driving the brake is connected to the electrodes on both sides of the conductive rubber, when a human finger or a part of the human body comes into contact with the outer deformable electrode. Since the conductive rubber is compressed to reduce the electric resistance, power is supplied to the actuator to operate the actuator.

As a result, the braking means fits between the lower frame of the sash and the lower frame of the window frame to apply a braking force to the sash.
The sash becomes immovable anymore, and it is possible to prevent an accident such as an injury due to impact force acting on a human body such as a finger.

Also in the case of claim 2, when a human body such as a finger touches the deformable electrode outside the vertical frame portion of the sash, it contacts the other electrode by that force and becomes electrically conductive. Since the actuator is energized by applying power and applies a braking force to the sash, it is possible to prevent the sash from moving further and applying an impact to the human body.

In both the first and second aspects of the present invention, the detector made of a conductive rubber type detector or a comb-shaped electrode has a simple structure and can be easily attached from the upper end to the lower end of the sash vertical frame portion. So that the entire sash vertical frame,
The sash can be stopped reliably by detecting contact with the human body.
