Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a retractable membrane structure in which wheels at the lower end of a pedestal run via a rail or the like and can be expanded and contracted.

[Conventional technology and its problems]

A large number of formworks that run on wheels attached to the lower ends of the pillars are connected in an expandable and retractable manner using movable braces, etc., and a membrane body such as a sheet is provided to cover the entire outer surface. Shrinking membrane structures are widely known.

In all conventional retractable membrane structures, the membrane was attached directly to the outer surface of each frame. In addition, there were problems such as the membrane of the frame often digging into the braces between the frames, causing severe damage, and making it difficult to completely close the entire structure.

[Means to solve the problem]

In view of these circumstances, the present invention, in this type of retractable membrane structure, separately fixes connectors to both ends of the beams of each frame, and attaches the upper end of each auxiliary column to the connectors. On the other hand, the technical feature is that the auxiliary column and the pedestal are connected and fixed by a support rod, and a membrane is provided to cover the entire outer surface.

[Effect]

By having the above structure, the present invention maintains a certain distance between the membrane body attached to the series of frames and each pillar, thereby ensuring that the membrane body does not dig in when closed and closed. It has the effect of preventing.

〔Example〕

Hereinafter, the configuration of the present invention will be described in more detail according to the embodiment shown in the figure.
This is a form frame body formed by connecting two frames by a T-shaped joint 2, and the pillars B to B of adjacent frame bodies 1 are connected by an expansion/contraction mechanism C such as a movable brace. Further, 3 is an auxiliary column installed outside each pedestal B in parallel with the pedestal at a certain distance, and 4 is a plurality of support rods connecting the pedestal B and the auxiliary column 3. .

In addition, in the figure, 5 is a membrane body installed to cover the above-mentioned series of frames, 6 is a wheel provided at the lower end of the pillar B, and 7
8 indicates a rail, and 8 indicates a motor for driving the wheels, and the rail 7 and motor 8 are installed as necessary.

Next, an example of the structure for attaching the auxiliary columns 3 to each of the frames 1 will be explained. As shown in FIG.
b, and the partition wall 2d of the auxiliary pillar joint part 2c, which is approximately T-shaped.
A connector 9 can be screwed into the connector 9, and the upper end of the auxiliary column 3 can be fitted to the outer end of the connector 9. Reference numeral 10 denotes a buffer made of rubber, plastic, metal, etc., which is interposed between the opening edge of the auxiliary column joint 2c and the connector 9.

Furthermore, as shown in the above figure A, the support rod 4 is
A cylindrical portion 4b through which the auxiliary column 3 can be inserted is connected to the base end of the armrest 4a, while a head bolt 4c is provided protruding from the other end surface, and a receiving bolt 4c is attached to the outer surface of the leg column B in advance. Although the armrest 4a can be locked using the tool 11, the base end of the armrest 4a is directly fixed to a bracket 4d etc. attached to the auxiliary column 3, as shown in FIG. You may also do so.

The means for locking the support rod 4 to the receiver 11 is, as shown in FIG.
A long hole 11b having a width corresponding to the diameter of the bolt 4c is bored from the upper edge of the front plate toward the center thereof, and a long hole 11b having a width corresponding to the diameter of the bolt 4c is bored at the lower edge of the receiver 11.
The arcuate edge 11c is centered on the axis of the bolt 4c inserted into the bolt, and the tip of the hook plate 4f rotatably attached to the bolt side is the arcuate edge 11c.
It is designed so that it can be engaged with.

Therefore, in assembling the series of frames of the present invention described above, first the beam fitting portions 2a of the T-shaped joint 2 are attached to both ends of the beam material A, and the pedestal fitting portions 2b of the above joint are attached.
After inserting the pedestal B into each of the frames, the pedestals B and B of the adjacent frames are connected telescopically using separate movable braces or the like. Next, the base end of the connector 9 is screwed onto the partition wall 2d by penetrating the buffer body 10 provided at the auxiliary column joint 2c of the joint 2, and the upper end of the auxiliary column 3 is externally fitted onto the connector. , by inserting the bolt 4c at the tip of the support rod 4 of the auxiliary column 3 into the long hole 11b of the receiver 11 on the pedestal and locking the hook plate 4f to the arcuate edge 11c, the auxiliary column 3 can be fixed. It is attached integrally to each frame 1.

Furthermore, in this case, the two frames 1 to 1 located at the front or rear end of the series of frames assembled as described above are connected by a connecting rod E or the like to form a fixed frame (the first (see figure), it is possible to maintain stable running of each frame during expansion and contraction, and especially for self-propelled membrane structures, the pedestal B and auxiliary column 3 of the fixed frame are This provides the convenience of being able to install the drive motor 8 using the available space.

Furthermore, although the above embodiments mainly describe indoor retractable membrane structures, when the auxiliary column 3 of the present invention is applied to outdoor retractable membrane structures that require ridge materials, the above-mentioned Instead of directly fitting the auxiliary column 3 to the connector 9 as shown in FIG. By fitting and fixing the upper end of the auxiliary column 3 into the lower cylinder part 12b and the both ends of the ridge material D into the upper cylinder part 12c, a retractable membrane structure with a ridge is immediately obtained. It is. Note that the connection between the pillars of each frame and the auxiliary pillars by the support rods 4 is the same as in the above embodiment.

[Effect of idea]

The contractible membrane structure of the present invention having the above configuration is as follows:
Because the auxiliary columns maintain a constant distance between the membrane and the pillars of each frame 1, the membrane does not dig into the braces etc. during a series of contractions of the frame 1. Therefore, damage to the membrane body can be prevented, and at the same time,
A reliable closed state can be obtained at all times. or,
For indoor use, by attaching a buffer to the auxiliary column joint of the T-type joint, the formation of sharp edges at that part is prevented, and the protection of the membrane is more effective.

In addition, with this invention, the individual frames including the auxiliary columns can be easily assembled without the need for complicated labor such as welding, and the workability is excellent. In particular, each frame can be constructed from straight wood. It has remarkable practical advantages, such as great convenience in changing dimensions and in storage and transportation.
