[0001]

[Industrial applications]

 The present invention relates to an automatic supporting or lifting device capable of automatically supporting a material or raising a material as a substitute for a work assistant.

[0002]

[Prior art]

 Conventionally, for example, when hitting a plywood on a ceiling, it was necessary for one or several assistants to hold the plywood. In addition, even when installing electric appliances etc. in the room, it was very troublesome for one worker to lift these electric appliances etc. Therefore, there is a problem that work efficiency does not increase. Therefore, in order to perform these operations, conventionally, auxiliary personnel were used, but recently there has been a problem that it is difficult to secure auxiliary personnel due to lack of manpower.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such a point, and provides an automatic support or lifting device capable of automatically performing work performed by an auxiliary person such as supporting a material or lifting a material. The purpose is to do.

[0004]

[Means for Solving the Problems]

 According to the configuration of the present invention which meets the above-mentioned object, a piston rod is fitted in a cylindrical body erected on a support base so that the piston rod can move up and down, a support tool is attached to the upper end of the piston rod, and an air from a compressor is installed. Thus, the piston rod is raised to support the material by the support tool or raise the material.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a cylindrical body 2 is erected on a support base 1, and a piston rod 3 having an open upper end and a closed lower end is vertically movably fitted to the cylindrical body 2 so as to move the piston. A support tool 4 is removably fitted to the upper end of the rod 3. A protrusion (not shown) is formed below the piston rod 3 so that the piston rod 3 does not reach the bottom of the tubular body 2. A hose 5 for supplying air into the tubular body 2 is connected to the tubular body 2, and the air from the compressor 6 is fed from the hose 5 to the tubular body 2 via a device 7 for adjusting the air supply and pressure. It is designed to be supplied into the body 2.

A ridge 8 is formed on the outer periphery of the lower end of the piston rod 3, and when the piston rod 3 is lifted by air pressure, the ridge 8 is formed on the inner peripheral surface of the upper end of the tubular body 2. The piston rod 3 is locked to the strip 9 so that the piston rod 3 does not come off the tubular body 2. A stopper 10 is attached to the upper outer periphery of the tubular body 2, and a protrusion (not shown) is passed through a hole (not shown) formed in the tubular body 2 by tilting the stopper lever 11 downward. Project inward, and the projection allows the piston rod 3 to be fixed so as not to move up and down.

The device 7 for adjusting the air supply and pressure used in the above-described embodiment turns on the compressor 6 and steps on the device 7 so that the passage for sending air to the hose 5 is opened. It has become. Further, the amount of air to be sent can be adjusted depending on the degree to which the device 7 is depressed with the foot, and thereby the pressure applied to the piston rod 3 can be adjusted.

When the apparatus of the present invention supports a plurality of places or when a large lift force is required, as shown in FIG. 2, the apparatus 7 for adjusting the air supply and pressure has a large number of units. It is advisable to connect the hoses 5 and the device of the present invention to each hose 5. Further, the support tool 4 can be replaced and mounted on the support tool 4 having various shapes according to the purpose of use of the present invention. The support in the embodiment of FIG. 1 is suitable for holding down the plywood, the support 4 shown in FIG. 3 is suitable for lifting the appliance 12 into position and shown in FIG. The support 4 is suitable for simply supporting a material in a narrow space or the like. The device 7 and the stopper 10 for adjusting the air supply and pressure used in the above embodiment are commercially available, and commercially available products can be used as they are.

FIG. 5 shows another embodiment of the present invention, showing an example in which the supply of air and the adjustment of pressure are performed by a switch 12 and a speed controller 16. Air from the compressor 6 is introduced from the hose 5 through the connector 13 through the hose 5a to the switch 12 for supplying and shutting off the air. By pushing the lever 14 of the switch 12 downward, the valve in the switch 12 is opened and the air passes through the switch 12. A push button 15 is attached to the upper end of the switch 12, and when the push button 15 is pushed, the air in the tubular body 2 is released to the outside so that the raised piston 3 can be dropped to its original position. Has become.

The air that has passed through the switch 14 is introduced into the speed controller 16. The speed controller 16 can freely adjust the size of the air passage by screwing the screw 17 in and out to adjust the flow rate of the air to adjust the rising speed of the piston rod 3. You can do it. The speed controller 16 is preferably adjusted in advance to have an appropriate air flow rate according to the purpose of use. The air that has passed through the speed controller 16 passes through the safety valve 18, passes through the hose 5b, and is introduced into the tubular body 2 through the inlet port 19 to raise the piston 3. The safety valve may be set to an appropriate value of about 5 atm.

In the above-described embodiment, the switch 12, the speed controller 17, and the safety valve 18 are fixed to the ring-shaped support base 20 fitted and fixed to the tubular body 2, but this is not always the case. However, it may be fixed to the upper end of the piston rod 3, for example. In the above embodiment, the switch 12 controls the air supply by the lever 12, but any device can be used as long as it can control the air supply, for example, a push button instead of the lever. Of course it's okay. Moreover, the speed controller 16 and the safety valve 18 are not always necessary in the present invention.

[0012]

[Action]

 Next, the operation of the present invention shown in FIG. 1 will be described. In FIG. 1, the piston rod 3 is fitted in the tubular body 2. It should be noted that the height of the tubular body 2 may be set to about the height of a human shoulder. In this state, the veneer plate is placed on the support base 4. Next, the compressor 6 is turned on, and a device 7 for adjusting the supply and pressure of air is stepped on, and air is introduced into the tubular body 2 through the hose 5. The piston rod 3 rises due to the pressure of air. When the veneer plate reaches a predetermined position, the stepping on the device 7 is stopped to stop the air supply, and at the same time, the stopper lever 11 is tilted downward to stop the piston rod 3 from rising and the compressor is compressed. The drive of 6 is stopped. In this state, the veneer plate is pressed to the fixing position, so it is possible to correct the position to some extent and fix it with a nail or the like. In this way, even a large plywood can be easily fixed to the ceiling or the like by one worker.

[0013]

【effect】

 As described above, according to the present invention, with a simple configuration, the work that was conventionally performed by the auxiliary personnel can be performed by one worker without using the auxiliary personnel, so that the labor is saved. However, it greatly contributes to the improvement of work efficiency.
