Description

[Detailed description of the invention] The present invention relates to a panel rotation connection device, and relates to a columnar connection member 1.
A grip part 2 having a substantially C-shaped cross section is provided over the entire length in the vertical direction, and a hollow cylindrical hinge shaft part 4 is provided at the side edge of the panel 3, with a part of the hinge shaft part 4 being cut out. , a spacer 6 having a large number of vertical cracks 5 longer than the notch 7 of the hinge shaft 4 on the outer periphery of the center part.
The upper part of the spacer 6 is fitted into the hinge shaft part 4 above the notch part 7 of the hinge shaft part 4, and the lower part of the spacer 6 is fitted into the hinge shaft part 4 below the notch part 7. This relates to a panel rotation coupling device in which the maximum diameter of the bulging part 8 is made larger than the front opening part 9 of the grip part 2, and the hinge shaft part 4 with the spacer 6 attached is inserted into the grip part 2. It is.

In the conventional panel rotation connecting device, a hollow cylindrical hinge shaft is provided at the side edge of a synthetic resin panel extending up and down, and the outer periphery of this hinge shaft is attached to an aluminum connecting member. Although it was inserted into the inner periphery of the grip section that had a roughly C-shaped cross section, if the outside diameter of the hinge shaft section was small due to irregular dimensions, the hinge shaft section could slip out of the front opening of the grip section and come off. there were.

Particularly in the case of panels made of extruded synthetic resin products, it is difficult to ensure the dimensional accuracy of the hinge shaft due to shrinkage during molding, etc., so the hinge shaft is easily removed from the gripping portion.

The present invention has been made in view of such conventional drawbacks, and its purpose is to make the maximum diameter of the central part of the notch of the hinge shaft larger than the front opening of the grip part. This prevents the part from coming off from the grip part.
Furthermore, by providing a number of vertical cracks in the center of the spacer that are longer than the notches in the hinge shaft, it is easy to fit the upper and lower parts of the spacer into the hollow cylindrical hinge shaft above and below the notches. An object of the present invention is to provide a panel rotation coupling device that can bulge out the center portion of a spacer.

The present invention will be explained in detail below using examples.

In the figure, reference numeral 1 denotes a hollow column-shaped connecting member made of extruded aluminum. The connecting member 1 is formed in a substantially half-moon shape in cross section, and a protrusion 10 is curved upward and downward on the approximately central shaft on the same surface. It has been done,
A roughly C-shaped gripping part 2 with two vertically parallel stripes is provided on the strong-faced roughly central shaft, and the open width l of the front opening 9 of the gripping part 2 The shape is smaller than the diameter d of the inner circumference of the holding part 2.

Reference numeral 4 denotes a hollow cylindrical hinge shaft portion integrally provided on the side edge of the synthetic resin panel 3 extending vertically, and a cutout portion 5 is provided by cutting out approximately the center of the hinge shaft portion 4 above and below. It is.

In the figure, reference numeral 6 denotes a cylindrical spacer, and a large number of vertical cracks 5, which are longer than the notch 7 of the hinge shaft portion 4, are provided on the outer periphery of the central portion.

However, if you press the spacer 6 with force from above and below, the center part of the cylindrical spacer 6 will bulge outward due to the presence of the vertical crack 5, and the vertical width will become shorter. 4, and by stretching the vertical width of the spacer 6 in this state, the upper part of the spacer 6 is inserted into the hinge shaft part 4 above the notch 7, and the lower part of the spacer 6 is cut out. The spacer 6 is inserted into the hinge shaft portion 4 below the portion 7 and attached to the notch portion 7 of the hinge shaft portion 4.

In this case, since the vertical crack 5 is longer than the notch 7, the center part of the spacer 6 still forms an outward bulging part 8 which bulges outward from the upper and lower parts of the spacer 6. The maximum diameter portion of the bulging portion 8 is larger than the front opening portion 9 of the grip portion 2.

Further, the maximum diameter portion of this outwardly bulging portion 8 is approximately equal to the inner diameter of the gripping portion 2.

In this way, with the spacer 6 attached to the notch 7, the hinge shaft 4 is fitted into the grip 2, and the panels 3 are foldably connected by the columnar connecting member 1 to form a partition wall or a bifold structure. It is designed to form doors, etc.

In the above embodiment, an example is shown in which the cutout portion 7 is provided in the center of the hinge shaft portion 4, but the cutout portion 7 may be provided at the top and bottom of the hinge shaft portion 4, or may be provided at three or more locations.

Note that caps (not shown) are provided at the upper and lower ends of the columnar connecting member 1.
is attached, and a portion of the cap covers the upper and lower ends of the panel 3 to prevent the connecting member 1 and the re-panel 3 from coming off in the vertical direction.

In the figure, reference numeral 11 indicates an arcuate portion at the end of the panel 3. This idea is
As mentioned above, by making the maximum diameter of the central part of the notch of the hinge shaft larger than the front opening of the gripping part, it is possible to prevent the hinge shaft from coming off from the gripping part. By providing a large number of vertical cracks in the center that are longer than the notches of the hinge shaft, when the upper and lower parts of the spacer are fitted into the hollow cylindrical hinge shaft above and below the notches, the center of the spacer can be easily removed. Also, when inserting the outwardly bulging part into the gripping part, the outwardly bulging part can be deformed due to the presence of vertical cracks, so the outwardly bulging part may not bulge out due to manufacturing errors. There is an advantage that the outwardly bulging portion can be inserted into the gripping portion even if the portion is slightly larger than the inner diameter of the gripping portion.
