Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a support device for a raised bed, in particular, the construction is simple, and the height position of the raised bed can be adjusted by a simple operation from the top of the raised bed after installation. The present invention relates to a lifting bed supporting device capable of correcting slack.

[Prior Art] Japanese Patent Application No. Sho 58-143760 (Actual No. Sho 60) as a lifting device that can adjust the height position of the lift and correct the slack with a simple operation from the top of the lift after installation. -51240) is known.

The above-mentioned conventionally known support device capable of adjusting the height position of the raised bed is a columnar support member having a thread groove formed at a predetermined height position, which is a vibration-proof member fixed to the floor surface. A fixing nut for fixing and a floor holding plate which are screwed to a fixing member supported on the upper side and are supported in an upright state, and which are vertically screwed into a screw groove formed at a predetermined position of the supporting member. A height adjusting nut fixed to the above is screwed, and the lift holding plate and a fixed nut sandwich the lift placed on the upper surface of the lift holding plate, and the support member is in a state where the fixed nut is loosened. By rotating the support member through the rotation operation groove formed on the top surface of the above, the height position of the lifting bed holding plate and the lifting bed stacked on the upper surface thereof can be adjusted.

[Problems to be Solved by the Invention] However, in the conventional supporting device capable of adjusting the height position of the lift, the base end of the columnar supporting member is supported in a state of floating from the floor surface.

Therefore, there is a problem that a heavy object such as a large OA device cannot be placed on the raised floor.

Further, in the conventional supporting device capable of adjusting the height position of the raised floor, the supporting member is formed to have the same diameter from the lower end to the upper end.

Therefore, when adjusting the height position of the lifting bed, there is a concern that the lower end of the supporting member may be pulled out from the fixing member fixed to the floor surface. It is also difficult to obtain sufficient supporting force because the members do not stand upright. In particular, the screwing state between the supporting member and the fixing member is a very important problem because the bed is shielded and cannot be visually confirmed.

Further, in the conventional supporting device capable of adjusting the height position of the bed, the lower end of the supporting member is screwed to the fixing member.

Therefore, when rotating the support member to adjust the height of the bed, the height positions of the bed and the support member themselves change at the same time, and when the height position of the bed changes significantly. However, there is also a problem in that it is difficult to operate a minute amount of height adjustment.

[Object of the Invention] The present invention has been made in view of such a point, and there is no concern that the lower end of the support member will be pulled out, and it is possible to place a heavy object on the lifting floor, and to further reduce the amount. An object of the present invention is to provide a lifting bed support device that can facilitate height adjustment.

[Means for Solving the Problems] The present invention has a columnar support body having a rotation operation groove on the top surface and a bulged base portion mounted on the floor on the bottom. A screw groove is formed at a predetermined height position of the support member, and a fixing nut for fixing and a height adjusting nut for lifting support are screwed up and down in the screw groove, and a fixing portion to the floor surface. And a fixing member for supporting the support member upright on the floor, the support member being disposed above the support member for rotatably fitting the support member above the base, and the adjustment nut is fixed. And a lifting bed holding plate having a positioning projection that is locked to the lower surface of the bed that is stacked on the upper surface thereof.

have.

Further, the fixing member 7 has a through hole 72 formed in the top surface of the central portion of the fixing portion 71 formed by bending a plate material having a substantially square plane into a convex shape, and the supporting portion main body 3 is cylindrical in the through hole 72 portion. A support portion 73 that can be freely rotatably fitted is fixedly fitted.

Lifting floor 1 is glass fiber reinforced concrete board, FRP
It is composed of a large number of lifting members 11 each having a square cut-out in the form of a plywood plate with each corner cut out, and a triangular projecting plate 13 joined to the lower surface of each of the lifting members 11 by a set screw 12.

The triangular projecting plate 13 has a plane of a right-angled triangle, a rectangular fitting hole 14 is formed at a predetermined position substantially parallel to the bottom side, and a corner having a right angle has a predetermined radius, that is, the support portion main body 3 An arc 15 with a radius equal to approximately half the outer diameter of
Is cut out.

Furthermore, the lifting bed holding plate 8 is formed in a square shape as a whole, and the cutting edges formed at the four corners are bent upward to form a triangular projecting plate 13.
A locking projection 81 for fitting into the fitting hole 14 formed at the corresponding position is projected, and the height adjusting nut 5 is fixed to the central portion.

In the drawings, reference numeral 61 is a washer that is inserted and arranged at a lower position of the fixing nut 6 of the supporting portion main body 3.

The present invention having the above-described structure is provided with a large number of support portion main bodies 3
Is inserted into the through hole 72 of the fixing member 7 from the bottom side thereof and the base portion 32 is accommodated in the concave portion 74 and fixed to a predetermined position on the surface of the floor 6 via the fixing portion 71 using, for example, an adhesive or the like. By doing so, the upright support is carried out, and at the same time, the adjusting nut 5 having the bed holding plate 8 fixed thereto is screwed into the thread groove 31 formed at the top of the support body 3.

Next, the adjustment nut 5 is rotated and four lifting members 11 each having a triangular protruding plate 13 fixed to the lower surface thereof are placed on the lifting holding plate 8 which is at a predetermined height position.

As described above, according to this embodiment, it is possible for anyone to easily and accurately form a smooth lifted floor without requiring flooring with specialized skills. Particularly, in this embodiment, the support portion main body 3 is used.
Since the base portion 32 formed in 1 is directly supported on the floor 4 surface, it is possible to place a heavy load on the lifting bed 1.

Further, in this embodiment, since the bed 1 is composed of the bed members 11 and the reinforcing triangular projecting plates 13 joined to the corners of the bed members 11, the bed 1 is relatively low in strength. It can be applied to the case where the member 11 is used, and the safety is sufficient, and the engagement protrusion 81 protruding from the lift holding member 8 is fitted and locked on the triangular projecting plate 13 which is separate from the lift member 11. Since it is not necessary to form the joint hole 14 and process the lifting member 11 which is difficult to process, the production is easy and economically advantageous.

Furthermore, in the present embodiment, the commercially available bolts can be used as they are as the support body 3, which is extremely economical.

The support body 3 itself does not move upward, fine adjustment is possible, and there is no concern that the bottom portion of the support body 3 will be pulled out from the fixing member 7 because the base 32 serves as a stopper.

Further, when the fixing nut 4 loosens or the floor shifts due to an earthquake or the like, the cap 10 is removed to expose the void P, and the fixing nut 4 is loosened using the driver 91 and the tool 92. In this state, the support portion main body 3 is rotated to correct the height of the bed 1 fixed to the adjusting nut 5 via the triangular protruding plate 13.

Therefore, the height of the raised bed 1 can be adjusted and the inclination can be corrected without peeling off the raised bed 1.

Further, at the time of adjustment, since the support portion main body 3 has a configuration in which the support portion 73 of the fixing member 7 is rotatably fitted and supported above the base portion 32, the support portion main body 3 itself moves upward. Fine adjustment is possible without doing.

FIG. 6 shows a different embodiment of the present invention, and the overall structure, operation and effect are almost the same as the above-mentioned embodiment, but the lift 1 is thin on a base such as synthetic resin, wood or foam concrete. It has a structure in which it is covered with a metal plate, does not have the triangular projecting plate 13 as in the embodiment shown in FIGS. 1 to 5, and has a locking projection 81 projecting from the lift holding plate 8. A fitting hole 14 for fitting and locking is formed directly on the lower surface of the floor 1.

In addition, four lifting members 11 assembled by abutting each other
A method of screwing the cap 10 covering the space P formed by the above to the top surface of the support body 3 with a set screw 34, or a small cap 35 fixed to the bottom surface of the cap 10 to the top of the support body 3. The cap 10 is fixed by being covered, and the cap 10 is surely fixed.

[Advantages of the Invention] According to the present invention having the above-described configuration, anyone can easily and accurately form a smooth lifted floor without requiring floor sticking with specialized skills, and a fixing nut can be used. Even if the bed is loose or the bed is displaced due to an earthquake, the height of the bed can be corrected with a very simple operation.

Further, since the platform formed on the support body is directly supported on the floor surface, it is possible to place a heavy object on the lifting floor, and the support body is rotatably supported by the fixing member to the floor. Therefore, the height of the raised bed can be adjusted within a minute range without fear that the lower end of the support member will be pulled out at the time of construction or adjustment.
