Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention attaches four suction cups (1) to a person's both hands and feet, by connecting a main pipe (7) to a vacuum generator and sucking air inside through a branch pipe (8). Then, the suction cups (1) are alternately adsorbed on the wall surface to allow the person to support his / her body weight by himself / herself, and to elevate / lower the wall surface. In firefighting activities, ladder cars cannot be used in high-rise buildings, and firefighters equipped with the present invention can climb the outer wall of the building to enter the upper floors.
It can also be used as a sports equipment for climbing walls.

[0002]

[Prior Art and Problems] Conventionally, portable ladders and the like are generally used for entry to the upper floor at a fire site where a ladder car cannot be used, but it is used if there is no scaffold to hang up the ladder. No, and it was extremely difficult to carry if the indoor passage was narrow. In general, in a fire-resistant building fire, it is often difficult to enter indoors due to thick smoke and hot air, and how to enter from the outside of the building by cutting off the entrance path from the indoor to the upper floor is a problem in fire fighting activities. It was

Further, in the field of sports, when climbing a wall surface, it was often impossible to climb the mountain without ruggedness on the wall surface and cracks on the wall surface for fitting the metal fittings for climbing.

[0004]

SUMMARY OF THE INVENTION The present invention enables a firefighter to go up and down the outer wall of a building, which has not been possible with conventional fire fighting equipment, to enter the upper floor. In addition, the present invention enables the climbing of a sports wall, which was impossible to climb on a nearly vertical wall without any clue.

[0005]

According to the present invention, a main pipe (7) connected to a vacuum generator is connected to four branch pipes (8) branched via four check valves (9). It consists of one suction cup (1), and the four suction cups (1) are two for the hand and two for the foot. Between the suction cups (1) respectively connected to the four branch pipes (8), a three-way valve type on-off valve (2) for switching between the vacuum suction side (14) and the atmosphere open side (15) is attached, and the switching is performed. The operation is performed by a link mechanism (6) that is interlocked with the movement of the handle (3) for the hand, and by a link mechanism (6) and return spring (5) that is interlocked with the movement of the footrest (4) for the foot. . The main structure of the sucker for hands (1) is the same as that of the sucker for feet, the difference between them is that the return spring (5) is attached to the foot, and the pedal (3) is attached to the hand grip (3). And footrest (4) with foot strap (12)
Is the point corresponding to.

[Action]

To operate the suction cup (1) for a hand, the grip (3) of the suction cup (1) is gripped by hand, and the grip (3) is moved downward while pressing the suction cup (1) against the wall surface. ) To the lower limit, the link mechanism (6) interlocks with that angle, and the switching angle (10) of the on-off valve (2) becomes the lower limit, and it becomes the vacuum suction side (14) and is connected to the vacuum generator. The air in the suction cup (1) is sucked through the main pipe (7) and the branch pipe (8), and the suction cup (1) is adsorbed and fixed on the wall surface.
Further, in this state, the handle (3) is moved upward and the handle operation angle (1
If you move to the upper limit of 1), link mechanism (6) at that angle
And the switching angle (10) of the on-off valve (2) reaches the upper limit, and the air is introduced into the suction cup (1) on the atmosphere open side (15) to release adsorption to the wall surface. This operation is consistent with the natural movement of a person trying to climb a wall. In addition,
Regarding the relationship between the switching angle (10) of the on-off valve (2) and the handle operating angle (11), while the switching angle (10) is 90 degrees, which is the same as a general three-way valve, the handle operating angle (10 2 if the handle 11 is about 10 cm long
Ideally, the link mechanism (6) should be 0 degrees or less. This is the result of several trials.

To operate the sucker (1) for the foot, attach the foot to the footrest (4) of the sucker (1) with the fixing band (12),
When the footrest (4) is moved downward while pressing the suction cup (1) against the wall surface, the suction cup (1) is adsorbed and fixed on the wall surface in the same manner as the manual suction cup (1) is operated. Further, if the footrest (4) is moved upward in this state, the suction to the wall surface is released similarly to the operation of the hand suction cup (1). In the case of the sucker for the foot (1), the return spring (5) acts when the weight of the foot is lifted and the weight is removed from the footrest (4), and the switching angle (10) of the open / close valve (2) becomes the upper limit and forced. It is switched to the atmosphere open side (15). This operation is consistent with the natural movement of a person trying to climb a wall.

Examples of the invention

The suction cup (1), which plays a major role in the present invention, has a bowl-like shape with its suction surface made of an elastic material such as rubber, and a non-air-permeable sponge is formed on the outer circumference of the suction surface. Since it is attached, even if there are some irregularities on the wall surface, it prevents air leaks and has a high adsorptivity. Further, as one of the features of the present invention, even if there is some air leakage, if the capacity of the vacuum generator which is connected to the main pipe (7) and constantly sucks vacuum exceeds the air leakage amount, Adsorbability does not drop.

The grip (3) and footrest (4) of the suction cup (1)
When a weight is applied to the sucker (1), a moment acts, and the sucker (1) is peeled off from the upper part of the sucker (1) with the lower part as a fulcrum. In order to prevent this, a support bracket (13) is attached,
The suction state of the suction cup (1) is extremely stable. Further, the support fitting (13) also has the effect of increasing the ground contact friction on the wall surface.

As a further safety consideration, the switching angle (10) of the three-way valve on-off valve (2) is set while one of the four suction cups (1) adsorbed on the wall surface is being operated. When in the middle, the suction cup (1) and the main pipe (7) and branch pipe (8) connected to the suction cup (1) may be open to the atmosphere, but the vacuum in the remaining three suction cups (1) is It is maintained by the action of the check valve (9).
In addition, even if the main pipe (7) is disconnected or the inside of the main pipe (7) is opened to the atmosphere due to a failure of the vacuum generator, the check valves (9) act to cause the inside of the four suction cups (1). The vacuum is maintained.

The reason why the return spring (5) is in the sucker (1) for the foot but not in the sucker (1) for the hand is that the foot does not perform as dexterously as a hand and that the hand does work as necessary. Therefore, if there is a return spring (6) when the handle (3) is released, the on-off valve (2) is on the atmosphere open side (15) and the suction cup (1) falls. This is the result obtained in many trials.

Therefore, even when climbing the wall, which has been a problem so far, a person wears the hand and foot suckers (1) of the present invention on both hands and feet to adsorb them on the wall surface to support the weight,
By alternately operating one by one and changing the positions of the limbs and moving the position of the body, it is possible to move up and down even on a vertical and slightly uneven wall surface.

[0013]

EFFECTS OF THE INVENTION According to the present invention, firefighters can move up and down on the wall surface of a fire building and enter the upper floor,
Firefighting and rescue activities have become easier.

Further, since the operation of the device of the present invention is consistent with the natural movement of a person ascending a wall surface and the safety is taken into consideration, it can be utilized as a climbing wall surface for sports.
