Description

[Detailed description of the invention] [Industrial application field] This invention prevents the slats of the shutter, etc., from tilting during opening and closing, and not being able to open and close vertically, which is so-called falling, in horizontally drawn blind shutters, etc. This relates to opening/closing devices such as horizontally pulling blind shutters.

[Conventional technology]

Conventionally, in horizontal blind shutters that open and close an opening laterally, a large number of slats have their upper and lower ends connected to upper and lower telescopic links, and a plurality of hanging rollers are attached to the upper telescopic links. A sliding member, which is suspended from the guide rail of the upper frame of the opening and is provided on the lower telescopic link, is adapted to engage with the guide rail of the lower frame of the opening.

[Problem that the invention attempts to solve]

When opening and closing such conventional horizontal blind shutters, the line of action between the opening/closing driving force and the combined reaction force such as the frictional resistance of the upper and lower guides of the shutter and the weight of the shutter, etc. Since they do not necessarily match, a tilting moment is generated in the slat, resulting in what is called falling. In particular, in the case of an electric opening/closing type, the opening/closing drive is generally performed by a motor or the like at the upper end of the slat, so the slat can only be opened and closed while keeping it vertical only when there is almost no frictional resistance on the guide rail of the lower frame of the opening. In addition, the guide rail of the lower frame is easily clogged with debris, and if the lower part of the shutter is obstructed by debris etc. from following the upper part of the shutter driven by the motor and the slat begins to tilt, the slat will be strained and further damaged by the upper and lower parts. The guide portion is restrained by the guide rails in the upper and lower frames, making it impossible to open and close, and eventually causing troubles such as damage to the slats and drive mechanism.

This invention was made to solve the above-mentioned conventional problems, and its purpose is to:
To provide an opening/closing device such as a side-pull blind shutter, which does not cause the slats to fall during opening/closing, whether manually or electrically, and keeps the slats vertical so that the shutters can be opened and closed smoothly at all times.

[Means for solving problems]

In order to achieve the above object, this invention provides upper and lower linear support members extending respectively to the upper frame and lower frame of a horizontal blind shutter, etc., and at least one end of each of the upper and lower telescoping links. A vertical rotating shaft is provided that passes through the telescopic link in the vertical direction, and upper and lower horizontal gears fixed to both ends of the vertical rotating shaft are respectively meshed with the upper and lower linear meshing members.

[Effect]

Therefore, in the opening/closing device such as a horizontally pulling blind shutter according to this invention, regardless of whether the driving force for opening/closing the shutter is applied to any position of the puller, whether manually or electrically, as the shutter being pulled laterally moves, The horizontal gears of the upper and lower telescopic links that mesh with the linear meshing members installed on the upper and lower frames of the opening are connected by a common vertical axis of rotation, so they rotate together, so that the slats can move up and down. Both are opened and closed without delay while remaining vertical.

〔Example〕

Hereinafter, one embodiment of this device will be described in detail with reference to FIGS. 1 and 2.

FIG. 1 is a schematic perspective view showing the configuration of a manually opened/closed horizontally pulling blind shutter to which the device of the present invention is applied, and FIG. 2 is a detailed side sectional view of the same shutter. In the figure, an opening 1 is formed into a frame shape by an upper frame 2, a lower frame 3, and left and right vertical frames 4, 5, and upper frames 2 and 3 have upper guides in the opening direction. A rail 6 and a lower guide rail 7 are extended.

The blind shutter that opens and closes the opening 1 is made up of a large number of vertical rectangular slats 8 whose upper and lower ends are connected by upper and lower telescopic links 9 and 10, respectively. It is said to be slightly larger than the area. Telescopic link 9,1
0 is a structure in which a large number of link pieces 11 and 12 are connected in an X-shape, and expands and contracts in the opening direction by changing the angle formed by the link pieces 11 and 12. A set of two hanging rollers 13 are attached to the upper telescopic link 9 at both ends and in the middle in the direction of expansion and contraction via roller support members 13a, and the slat 8 is suspended from the upper guide rail via the hanging rollers 13. be done. Further, the lower telescopic link 10 is appropriately provided with a sliding member 14 projecting downward and engaged with the groove-shaped lower guide rail 7.

A vertical rotation shaft 15 is provided at the pull-side ends of the upper and lower telescoping links 9, 10, and vertically passes through both the telescoping links 9, 10 and extends into the upper frame 2 and lower frame 3. Upper and lower horizontal gears 16 and 17, each made of a pinion or a sprocket, are fixed to the upper and lower ends of the gear 15, respectively. On the other hand, in the upper frame 2 and lower frame 3 of the opening, upper and lower linear meshing members 18 and 19 consisting of rack gears or chains that mesh with the upper and lower horizontal gears 16 and 17 are provided extending in the opening direction. The horizontal gears 16 and 17 are meshed with upper and lower linear meshing members 18 and 19, respectively. A pull handle 20 that does not rotate is mounted on the vertical rotation shaft 15, and the side of the shutter opposite to the pull handle is fixed to one of the vertical frames 5.

In the device of the present invention having such a configuration, the puller 20
When the shutter is moved by hand in the opening/closing direction of the shutter, no matter where the point of force is above or below the puller 20, the upper and lower guide rails 6 and 7, the upper hanging roller 13, and the lower Even if the respective frictional resistances with the sliding member 14 are unequal, the driving force of the puller 20 rotates the upper and lower horizontal gears 16, 17 connected by a common vertical rotation shaft 15, and therefore the upper and lower The horizontal gears 16 and 17 move at the same speed with respect to the upper and lower linear meshing members 18 and 19 that mesh with them, and the slats are opened and closed while maintaining their vertical position without any tilting.

If upper and lower horizontal gears connected by a vertical rotation shaft are installed on both sides of the shutter, the shutter can be opened and closed from either the left or right side without tipping over.

FIG. 3 is a perspective view of the main parts of an embodiment in which the device of the present invention is applied to an electric horizontally pulling blind shutter.
Components that are the same as those in the previous embodiment are given the same reference numerals.

In this embodiment, a motor 21 is attached to one end of the upper frame 2 of the opening 1, a horizontal pulley 22 is fixed to the output shaft of the motor 21, and a horizontal pulley 22 is fixed to the other end of the upper frame 2. Endless belt 2 between pulley 23
4 is on a rack. One side of the endless belt 24 is fixed to a roller support member 13a at the end on the shutter handle 20 side. The rest of the structure is similar to the manual embodiment, and when the motor 21 is rotated in the opening or closing direction by an open/close switch (not shown), the belt 24 is driven and the shutter is electrically opened/closed. At this time, the shutter is driven to open and close at the top of the axis of the pull handle 20, but due to the action described above, the shutter is opened and closed while maintaining its vertical position without falling over.

As described in detail above, according to this invention, upper and lower linear engagement members are provided extending on the upper frame and lower frame of a horizontal blind shutter, etc., and at least one end of each of the upper and lower telescopic links is provided with both upper and lower linear engagement members. A vertical rotating shaft passing through the telescopic link in the vertical direction is provided, and upper and lower horizontal gears fixed to both ends of the vertical rotating shaft are meshed with the upper and lower linear meshing members, respectively, so that it can be operated manually or electrically. No matter where the driving force for opening and closing the shutter is located on the pull axis, as the shutter moves horizontally,
The upper and lower horizontal gears move at the same speed relative to the upper and lower linear meshing members that mesh with them, and the slats are opened and closed while maintaining their vertical position without causing any tilting. Therefore, it is possible to prevent troubles such as the shutter becoming unable to open or close during opening/closing or damage to the slats or drive mechanism, which is a practically beneficial effect.
