Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a continuous device for folding partition plates that can be freely folded like an accordion curtain.

Conventionally, as a continuous device for this type of folding partition plate, shaft parts are provided symmetrically on both sides of the connecting member, and a cylindrical part with an incision on the front surface provided on the partition plate is fitted into this, and Therefore, a configuration in which the partition plate can be horizontally rotated to unfold and fold within the regulated range is commonly used.

In a continuous device having this type of structure, during use, the incision of the cylindrical portion provided at the edge of the partition plate gradually expands, and the shaft portion of the connecting member may eventually come off the opening.

Therefore, if the thickness of the member used is increased in order to prevent this, the amount of material used will increase, the weight will also increase, and various difficulties arise in terms of handling.

On the other hand, the actual unfolding angle of the partition plates required for the partition plates to unfold from the folded state where they overlap each other into a single plate is only 90 degrees, but from a practical point of view, it is acceptable. It is desirable to increase the expansion angle because it reduces the occurrence of shocks and breakdowns, and is also convenient in terms of handling.

However, increasing this unfolding angle means enlarging the incision of the connecting part formed on the edge of the partition plate, which reduces the degree of fitting with the connecting member and makes it easier to come off, making it difficult to withstand long-term use. There are drawbacks. The present invention was invented in view of the above-mentioned points, and basically consists of two concentric sliding arcuate surfaces with different radii formed on a connecting member, and an inner and outer abutment provided opposite to the edge of a partition plate. To provide a continuous device of partition plates which are sandwiched between the pieces and connected so as to be slidable and rotatable, thereby increasing the connection strength and allowing a sufficiently large unfolding angle, which is also convenient in terms of handling. It is something. Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a connecting member and 2 is a partition plate.

On both sides of the connecting member 1, an inner shaft portion 3 and an outer shaft portion 4 having different radii are integrally formed with an arcuate groove 5 that is open to the front surface. Two concentric sliding circular arc surfaces 3.a and 4a with different radii are formed in a range exceeding 90 degrees.

At the edge of the partition plate 2, there is an inner piece 6 that connects to the inner shaft sliding arc surface 3a from the front side of the connecting member 1 within a range of at least 90 degrees, and an inner shaft sliding member 6 that connects to the inner shaft sliding arc surface 3a from the rear side of the connecting member 1. An outer cover piece 7, which is partially joined to the arcuate surface 4a, is provided to face the outer cover piece 7. In addition, 8 in the figure is a connecting part that connects the inner shaft part 3 and the outer shaft part 4 of the connecting member 1, and 9
is a space formed between the inner and outer abutment pieces 6 and 7 of the partition plate 2.

However, in order to continuously connect the connecting member 1 and the partition plate 2, it is necessary to insert the inner and outer shaft parts 3 and 4 of the connecting member 1 into the partition plate 2 from the upper and lower ends of the space 9 formed between the inner and outer abutment pieces 6 and 7. The two partition plates 2, 2 are continuously joined together.

FIGS. 2A, 2B, and 2C are explanatory diagrams of a connecting structure showing another modified embodiment of the present invention.

In Figure a, the expansion angle of the partition plate 2 is set to 90 degrees, but the joint range of the inner piece 6 of the partition plate 2 surrounding the inner shaft portion 3 of the connection member 1 is set to 90 degrees or more for connection. There are configurations with increased strength.

In Figure b, the connecting part 8 between the inner shaft part 3 and the outer shaft part 4 of the connecting member 1 is set at the end of the outer shaft part 4, the circular arc groove 5 is formed on one side of the inner shaft part 3, and the partition plate 2 is The deployment angle is set to 90 degrees or more.

In Figure c, the connecting part 8 between the inner shaft part 3 and the outer shaft part 4 of the connecting member 1 is set directly behind the inner shaft part 3, the arcuate grooves 5 are distributed and formed on both sides of the inner shaft part 3, and the partition plate No. 2 has a configuration in which the deployment angle is set to 90 degrees or more.

The present invention is constructed as described above, and the connecting member is provided with inner and outer shaft parts on both sides thereof, each having two concentric sliding arcuate surfaces with different radii in a range exceeding 90 degrees,
The edges of the partition plate are provided with inner and outer abutment pieces that are connected to the inner and outer shaft parts, respectively, and the inner and outer abutment pieces of the partition plate are connected in such a way that the inner and outer axle parts of the connecting member are sandwiched from symmetrical positions. Because it is configured to be rotated by rotating the shaft, it is easier to rotate when the connecting part comes off compared to the conventional shaft part and the rotating part that rotates on a single sliding arc surface, which is seen in fitting with a cylindrical part with an incision. It achieves well-balanced, smooth, and reliable rotation without any risk of damage, and the rigidity of the inner and outer shafts is reduced by providing the inner shaft integrally with the outer shaft via a connecting part. It has been greatly improved, has good stability against twisting, etc., and can withstand long-term use, and can be used in various forms other than those shown in Figure 2 depending on the purpose of use, or as folding doors for bathrooms, etc. It is highly versatile as it can be applied to hinges for various doors using the one side connection part of the connecting member, and it is also easy to manufacture using lightweight metals such as aluminum and can be provided at low cost through mass production. In terms of handling, it has a rotation angle that is considerably more generous than the practical rotation angle for unfolding and folding the partition plate, and has great practical effects, such as quiet operation without generating shocks.
