Description

[Detailed Description of the Invention] Technical Field This invention relates to a partition door that rotatably connects a plurality of panels with a hinge.

Prior art In a partition door, a large number of panels are movably suspended from a hanger rail fixed to the ceiling, and by pulling out each panel along the hanger rail and putting them together, the indoor space is divided as appropriate. It is something. Conventionally, in such partition doors, each panel is connected with two hinges, and when in use, the connected panels are opened in a straight line along the hanger rail and brought together, and when not in use, the panels are folded at the hinges. A device that can be folded and stored has been proposed.

However, in such a partition door, when the panels are assembled along the hanger rail, it is necessary to restrict the rotation of the hinge portion to stably maintain each panel in a straight line.

Purpose The purpose of this invention is to provide a hinge that rotatably connects the panels of a partition door, so that when the panels are opened in a straight line and brought together, the state can be stably maintained, and the hinges can be used to The objective is to provide a hinge that can be applied to panels in a simple configuration.

Structure of the invention The structure of this invention consists of a hinge frame with a groove-shaped cross section attached to the side edge of the panel, a joint frame that rotatably engages with the tip of one side of the hinge frame, and a joint frame that rotatably engages with the tip of one side of the hinge frame. The panel can be rotated by attaching a hinge consisting of a gutter-shaped finger guard that is fitted and fixed to the frame and a stopper piece made of an elastic metal plate that is removably attached to the arc-shaped peripheral edge of the finger guard. The hinge frame is movably connected, and at the tip of the local side of the hinge frame, a regulating piece is provided that elastically engages with the stopper piece when the connecting panel is opened linearly. .

Embodiment An embodiment embodying this invention will be described below with reference to the drawings. In FIG. 1, a partition door 1
A large number of panels 2 constituting the system are connected two by two by hinges 3, and are movably suspended from a hanger rail 5 fixed to a ceiling surface etc. by runners 4 provided at the upper end of each panel 2. . Then, the partition door 1 can be constructed by opening the panels 2 connected by the hinges 3 in a straight line along the hanger rail 5 and sequentially assembling these two panels 2 together.

Furthermore, the partition door 1 can be opened by folding the panels 2 connected by the hinges 3 in a direction perpendicular to the hanger rail 5 and moving them to one side of the hanger rail 5.

The detailed structure of the hinge 3 that connects the panels 2 is shown in the second
Referring to FIGS. 5 to 5, as shown in FIG. 2, a hinge frame 6 is symmetrically attached to the side edge of the panel 2 on which the hinge 3 is attached. The hinge frame 6 has a groove-like side edge of the panel 2 formed by both side edges 7 and a bottom edge 8, and an arcuate surface 9 is formed at the tip of one side edge 7, and a concave portion 10 having an arcuate cross section is formed inside of the arcuate surface 9. ing. A regulating side 11 that projects inward is formed at the tip of the other side 7.

The joint frame 12 is provided with opposing protrusions 13 on one side thereof, which correspond to the concave portions 10 of the hinge frame 6, and the protrusions 13 are provided on the opposite sides of the concave portions 10 of the hinge frames 6 of the two panels 2. Once fitted, both panels 2 can rotate about the joint frame 12 in the direction of arrow A in FIG.
A hook-shaped fitting piece 14 is provided on the other side of the joint frame 12.

The finger guard 15 is made of a flexible material such as vinyl chloride and is molded into a gutter shape, and a hook-shaped fitting piece 16 that corresponds to the fitting piece 14 of the joint frame 12 is integrated inside the finger guard 15. It is set in. Then, both the fitting pieces 14 and 16 are fitted, and the finger guard 15 is attached to the joint frame 1.
It is fixed at 2. Projections 17 are formed on both sides of the joint guard 15 to face outward, and when the two panels 2 connected by the hinge 3 are folded into a parallel state as shown in FIG. is adapted to come into contact with a regulating piece 11 provided at the tip of the other side 7 of the hinge frame 6. A stopper piece 18 is detachably screwed to the center portion of the arcuate outer peripheral surface of the finger guard 15 in the left-right direction. The stopper piece 18 is formed by press-molding an elastic metal plate, for example, a thin plate made of stainless steel, as shown in FIGS.
and the diagonal pieces 20 on both sides are continuous on the circular arc surface 21. The groove 19 is provided with a through hole 22 for screwing the stopper piece 18 to the finger guard 15. And, such a stopper piece 18
is attached with the tip of the oblique side 20 in close contact with the outer peripheral surface of the finger guard 15. Next, the operation of the hinge configured in this way will be explained.

As shown in FIG. 3, when the two panels 2 connected by the hinge 3 are folded in parallel, the protrusion 17 of the finger guard 15 comes into contact with the regulating piece 11 of the hinge frame 6. Further rotation of the is prevented. Therefore, when the panels 2 are folded, the two panels 2 do not collide and generate noise.

When the panel 2 is opened from the folded state using the hinge 3 as a fulcrum, the regulating piece 11 of the hinge frame 6 slides against the outer peripheral surface of the finger guard 15, and the panel 2 rotates using the protrusion 13 of the joint frame 12 as a fulcrum. move.

Then, the regulating piece 11 eventually becomes the stopper piece 18.
However, when both panels 2 are further rotated from this state, the stopper piece 18 is pressed and flexed, and as shown in FIG.
At the same time, the protrusions 17 on both side edges of the finger guard 15 come into contact with the sides 7 of the hinge frame 6. Therefore, when both panels 2 are opened in a straight line, further rotation is prevented, and unless a force greater than a predetermined value is applied in the folding direction to cause the regulating edge 11 to overcome the arcuate surface 21, rotation will not occur. Since this is prevented, both panels 2 are stably maintained in this state.

As described above, in this embodiment, when the panels 2 connected by the hinges 3 are pulled out in a straight line along the hanger rail 5 and assembled together, the hinge 3 has the regulating piece 11 in the groove 19 of the stopper piece 18. The panels 2 can be easily folded by engaging each panel 2 to stably maintain it in a straight line state, and applying a force sufficient to cause the regulating piece 11 to overcome the arcuate surface 21 of the stopper piece 18 from this state. In addition, since a removable stopper piece 18 that elastically engages with the regulating piece 11 is provided, especially in the case of a heavy panel 2, the regulating pieces 11 of the panel 2 once pulled out collide with each other and bounce back due to inertia force. In such cases, the stopper piece 18 can be applied to panels of various sizes and weights simply by attaching and detaching it.Since the stopper piece 18 is attached to the finger guard 15 as a separate body, the rigidity of the finger guard 15 can be increased. Does not decrease. Furthermore, its structure is extremely simple.

Effects As detailed above, this invention is a hinge that rotatably connects the panels of a partition door, and is capable of stably maintaining the state when the panels are opened in a straight line and brought together. Since the structure is provided with a removable stopper piece that elastically engages with the regulating piece, for example, when a heavy panel is pulled out, a considerable inertial force is generated, so once the panel is pulled out, the force will cause the regulating piece to collide with each other. When the hinge hits the hinge, it may rebound, and at this time, a large torque is applied and the hinge may overcome the arcuate surface of the stopper piece. In this case, a stopper piece with a certain height is required, but even in this case, there is no need to go out of your way to replace the entire hinge. By making several types of stopper pieces that adapt to the expected torque, and replacing only the stopper pieces, it can be applied to panels of various sizes and weights, increasing the versatility of the hinge and having great practical value. Become.

Further, since the stopper piece is separately attached to the finger guard, the present invention exhibits various excellent effects such as not reducing the rigidity of the finger guard.
