Description

[Detailed description of the invention] This invention relates to an improvement of a panel type shutter opening/closing device.

Recently, multiple tiers of upper and lower panels connected by a chain are developed in the same vertical plane between a pair of left and right vertical guide rails placed on both sides of the shutter opening/closing opening, and these panels are connected to the above guide rails. A panel type shutter device is provided in which each of the panels is suspended in a parallel and adjacent folded state when the panels are moved and stored in a storage box above the rail.

This type of conventional panel shutter device is
It has many advantages, such as less noise generated when the panel moves, the ability to widen the panel width, and an excellent appearance.

However, in the above-mentioned conventional panel type shutter device, a pair of left and right panel connecting chains are meshed with a pair of left and right panel drive sprockets in each system, and these panel drive sprockets are driven to rotate synchronously. Since the panel is designed to move up and down, misalignment of the gear teeth between the sprockets for driving the two panels may cause the panel suspended by the chain to tilt, which may interfere with the up and down movement of the panel. There were problems such as the panel becoming twisted and damaged.

This idea was made to solve the above problem, and is a panel-type shutter opening/closing system that allows multiple interconnected panels to move smoothly and reliably along a predetermined transfer path without tilting. The purpose is to provide equipment.

The panel-type shutter opening/closing device according to this invention has a plurality of upper and lower shutters that move up and down along a pair of left and right guide rails that are arranged upright on both sides of a shutter opening/closing opening and have horizontal rails whose upper ends are curved and extend horizontally. On each side of the top edge of the tiered panel,
A protruding shaft that can be engaged and moved to the horizontal rail portion is protruded, an upper cam is rotatably supported near the curved portion of the upper end of the guide rail, and near the bottom of the upper cam, each of the panels rotatably supports a lower cam that sequentially removably engages with the protruding shaft of the panel and moves the panels up and down along the guide rail, while transferring the protruding shaft to and from the upper cam. Further, the upper cam is provided with transfer engagement grooves at substantially symmetrical positions for transferring the protruding shafts of the two adjacent panels between the lower cam and the horizontal rail portion. It is something.

In the panel-type shutter opening/closing device of this invention, when the upper cam and the lower cam are rotated synchronously in the panel storage direction, the lower cam engages with the protruding shaft of the preceding panel and pushes the protruding shaft upward, thereby allowing multiple stages of upper and lower stages to be moved. Each panel moves upward along the guide rail. During this process of raising the panel, the lower cam transfers the protruding shaft of the preceding panel to one of the transfer engagement grooves of the upper cam. Thereby, the upper cam transfers the protruding shaft of the preceding panel to the horizontal rail portion through the upper end side curved portion of the guide rail. During this transfer, the lower cam pushes up and transfers the protruding shaft of the succeeding panel, and transfers this protruding shaft to the other transfer engagement groove of the upper cam. Therefore, the upper cam positions two adjacent panels and smoothly and reliably transfers the panels in a predetermined transfer direction in a state where two panels are prevented from falling.

An embodiment of this invention will be described below based on the drawings.

The panel type shutter device 1 shown in FIG. 1 includes a pair of left and right guide rails 2 arranged on both sides of a so-called shutter opening/closing opening such as an entrance/exit of a building or a window.
It is equipped with a plurality of upper and lower panels 3 whose both sides are fitted into and engaged with these guide rails 2 so as to be able to move up and down, and a panel storage box (hereinafter referred to as storage box) 6 arranged on the upper part of the guide rail 2. ing.

Both guide rails 2 have horizontal rail portions 2a whose upper ends are curved and extend in the vertical direction.

Further, the panels 3 are connected to each other by links 7 so as to be flexible.

That is, each panel 3 has a protruding shaft 3a that protrudes from both sides of its upper end, and an intermediate protruding shaft 3b that protrudes near the intermediate portion of both sides.

In each panel 3, one end side of the link 7 is loosely fitted and connected to the upper end protruding shaft 3a of one of the adjacent panels 3 through a long hole.
The other end portion is rotatably connected to the intermediate protruding shaft 3b of the other panel 3.

Further, in the storage box 6, an upper cam 5 is rotatably supported near the curved portion of the upper end of the guide rail 2, and a lower cam 4 is rotatably supported near the lower portion of the upper cam 5. has been done.

The lower cam 4 has claw portions 4a on both end sides, and the claw portions 4a move the upper end protruding shaft 3a of the panel 3 along the guide rail 2 within the movement path of the upper end protruding shaft 3a.
It is designed to rotate so that it can be engaged and detached from a.

The lower cam 4 is connected to the protruding shaft 3 of each panel 3.
The projecting shaft 3a is transferred between the upper cam 5 and the upper cam 5 while each panel 3 is moved up and down along the guide rail 2 by sequentially engaging with the upper cam 5, and can be rotated in forward and reverse directions manually or by power. I'm starting to feel like I'm being forced to do that.

The upper cam 5 is formed into a disk shape, and its circumferential portion 5b rotates while slidingly contacting the protruding shafts 3a of both the preceding panel 3 and the following panel 3, and the rotation is controlled by the lower cam 5. As in the case of the cam 4, it can be operated manually or by power. In this case, the upper cam 5 preferably rotates in synchronization with the lower cam 4.

At approximately symmetrical positions of the upper cam 5, there is a pair of transfers for transferring the protruding shafts 3a of two adjacent panels 3 between the lower cam 4 and the horizontal rail portion 2a. An engagement groove 5a is cut out.

Next, the operation will be explained.

With each panel 3 extended between the guide rails 2, when the upper cam 5 and the lower cam 4 are rotated synchronously in the panel storage direction (clockwise in FIG. By engaging the protruding shaft 3a of the preceding panel 3 at the portion 4a and pushing up the protruding shaft 3a, all subsequent panels 3 move upwardly along the guide rail 2 following the preceding panel 3. Here, when the protruding shaft 3a of the preceding panel 3 is pushed up to point B in FIG.
It is scooped up at point a and transported to point A on the horizontal rail section 2a. Note that the above point B is located at the contact point between the upper cam 5 and the lower cam 4, and is also located at the point of contact between the upper cam 5 and the lower cam 4, and the protruding shaft 3a of the panel 3.
When is transferred from point B to point C, the protruding shaft 3a of the subsequent panel 3 is located at point D, which becomes the starting point of abutting engagement with the claw portion 4a of the lower cam 4.

As described above, in the process in which the protruding shaft 3a of the preceding panel 3 is transferred by the upper cam 5 to the vicinity of point A of the horizontal rail portion 2a, the claw portion 4a on the other end side of the lower cam 4 is moved to the subsequent panel 3. engages with the protruding shaft 3a of the
The protruding shaft 3a is pushed up and transferred to the other transfer engagement groove 5a of the upper cam 5.

In this operation, the following panel 3
It is repeated every time the neighborhood of is reached.

Therefore, the upper cam 5 positions two adjacent panels 3 in one rotation, and smoothly moves the panels toward the horizontal rail portion 2a along a predetermined movement path in a state where two panels are prevented from falling. Transport securely.

In this way, the panels 3 that have been sequentially transferred to the horizontal rail portion 2a are suspended with their respective protruding shafts 3a engaged with the horizontal rail portion 2a, and are stored in a folded state.

When the lower cam 4 and the upper cam 5 are reversely rotated from such a panel storage state, the transfer engagement groove 5a of the upper cam 5 sequentially receives the protruding shaft 3a of the panel 3 from above the horizontal rail portion 2a, and Projecting shaft 3a
The respective panels 3 are fed out between the guide rails 2 by sequentially passing them to the claw portion 4a of the lower cam 4.

As described above, according to this invention, each of the upper and lower multiple stages of panels in a panel type shutter device can be smoothly moved in a predetermined vertical direction and horizontal direction by the upper cam and the lower cam, and,
Since the upper cam positions two adjacent panels and transports the panels in a manner that prevents them from falling, the panel transport operation can be performed reliably.
