Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a canopy opening/closing device in which the canopy of a greenhouse, sunroom, etc. is composed of a plurality of panels, and these panels are made movable.

[Prior Art] As shown in FIG. 6, Utility Application No. 1987-90170, which was previously filed by the present applicant, discloses that the left and right guide rails 62, 63 and the guide rails 62, 63 are arranged near a frame 61. A movable panel 67 is connected to the cable 68 and has a caster 64 that runs in contact with the guide rail 63 and a roller 66 that runs while being guided by an intermediate guide rail 65 that is arranged in the center of the guide rails 62 and 63. ing.

One end of the cable 68 is fixed to a separately prepared lifting shaft, and as the shaft rotates, the cable 68 is pulled and the panel 67 is moved up and down.

On the other hand, at the upper and lower ends of the guide rails 62 and 63 that support the movable panel 67, there are elevating shafts 6 that are installed horizontally at the upper or lower part of the building H such as a house.
A guide rail spindle 73 is fixedly provided with a worm gear 72 that is screwed into a worm wheel 71 provided on the guide rails 9 and 70.

Furthermore, a female thread is carved into the boss of the worm gear 72, while a male thread is formed on the outer periphery of the guide rail spindle 73.

In addition, the lowest level of the building H is formed by a fixed panel 74, and the fixed panel 74 and the cam portion of the intermediate guide rail 65 as well as the vertical support section 65 below it.
The space defined by b is a panel storage section 75.

When the panel 67 is moved from the closed state to the open state, that is, when the panel 67 placed in a sealed state is moved downward along the slope due to the necessity of ventilation or room temperature control, first, the guide rail 62, 6
3 is lowered toward the indoor side by a distance equal to or more than the thickness of the panel 67 with the moving panel 67 placed thereon.

Next, the shafts 69 and 70 for raising and lowering the panel are rotated electrically or manually, thereby rotating the worm wheel 71 and rotating the female thread on the worm gear 72 that is threaded therewith. As a result, the male screw of the guide rail spindle 73 is guided by this female screw and moves in its axial direction, and the spindle 73 is lowered and the guide rail 6
2,63 is lowered.

Thereafter, a shaft for raising and lowering the panels is separately operated to sequentially move the movable panels in the direction of the slope, and shift to the open state.

By the way, to move the panel to the closed state, drive the shaft for raising and lowering the movable panel in the opposite direction to the above, pull the panels upward one by one, cover the canopy, and then rotate the shaft in the opposite direction. After the spindle is raised to a level where the fixed panel and the movable panel are connected in series, the rotation is stopped to keep the room airtight.

[Problems to be Solved by the Invention] The above application discloses a guide rail spindle and a moving panel in which a shaft is installed horizontally at the upper and lower parts of a house for raising and lowering a guide rail, and this shaft is equipped with a worm wheel and a worm gear that is screwed thereto. Although it has been possible to raise and lower movable panels extremely smoothly by using members such as intermediate guide rails and casters, and to finely adjust the elevation and descent of each movable panel, the shafts and guide rail spindles Support members, etc. (not shown) protrude into the room, which is disadvantageous for effective use of space.

In addition, the raising and lowering of the guide rail and the movement of the moving panel in the direction of the slope can be done either electrically or manually.
Since this is achieved by rotating the shaft forward and backward, it is necessary to rotate a separately prepared handle, especially when doing it manually, so improvements in operability have been desired.

Therefore, the present invention has been developed to simplify the opening/closing device in buildings such as greenhouses, as well as provide operability that allows the movable panel to be moved as if operating a blind, and a canopy that allows for effective use of indoor space. The present invention provides a switchgear for this purpose.

[Means for Solving the Problems] The present invention divides the canopy panel of a building H such as a greenhouse into two or more parts along the slope direction, and supports these panels on guide rails arranged on the left and right sides of the panels. In order to open and close the canopy by moving freely in the direction of the slope, a fixed frame forms the framework of the building, a guide rail on which multiple movable panels are placed,
This canopy opening/closing device consists of a cam that manually raises and lowers the guide rail, cables that move the movable panel in the direction of the slope, and a stopper.

[Function] To change the canopy panel from the closed state to the open state,
After rotating the cam placed below the guide rail and lowering it to the indoor side of the guide rail, operate the cable to lower the movable panel downward along the slope.
Lock the rope at any point with a stopper,
Fix the panel.

In addition, to shift from the open state to the closed state, perform the opposite operation to the above, that is, release the locking of the cables, pull the movable panel upwards, lock the cables to the stopper at a predetermined point, and then The cam is rotated to raise the guide rail toward the outdoors, and the movable panel is brought into contact with the packing material described below, thereby sealing the room.

[Example] The present invention will be explained in more detail based on an illustrated example.

Fig. 1 is a partially cutaway perspective view of a building such as a greenhouse with a sloped roof or canopy showing the opening/closing device of the present invention, Fig. 2 is an explanatory view showing the moving state of the panel, and Fig. 3 is an A -A sectional view, FIG. 4 is a BB sectional view, and FIGS. 5 a to 5 c are explanatory diagrams showing the operating state of the stopper.

As shown in the figure, with respect to the fixed frame 1 and center frame 2 arranged in the direction of the slope of the building,
Guide rails 3 and 4 that move up and down in a direction perpendicular to that
A movable panel 5 is placed on the guide rails 3 and 4, in which a transparent body made of resin, glass, or a composite thereof is fixed within a frame.

The panel 5 is divided into two or more parts along the gradient direction, one end of the cable 6 is fixed to the upper end of the panel 5, and a pulley 7 supported by the upper frame 1a is attached to the other end.
It is latched to a stopper 8 through .

On the other hand, a handle 11 for rotating the cam 9 is fixed to a camshaft 10 to which a cam 9 for vertically moving the guide rails 3 and 4 is attached.
Both ends thereof are vertically mounted on the fixed frame 1 and the center frame 2, and are pivotally supported by shaft holders 12 fixed to the upper and lower ends of the fixed frame 1 and the center frame 2 in the gradient direction.

Further, a pair of lift frames 13 are fixed slightly inside the shaft holder 12. Incidentally, the lift frames 13 have an L-shaped cross section, for example, and a linear shaft 13' is fixed to the horizontal portion of the lift frames 13. has been done.

In addition, a bearing holder 14 is provided, the upper end of which is fixed to the guide rails 3 and 4, and which includes a bearing 14' into which the linear shaft 13' is inserted and slid.

On the other hand, on the indoor side of the fixed frame 2 and the center frame 3, a packing material 15 made of rubber or resin, etc.
is fixed as shown in the figure.

Incidentally, the building H shown in FIG. 1 has fixed panels 5',
5'' are arranged respectively.

Furthermore, the stopper 8 has a stopper frame 8a attached to the lower end of the support member 1b vertically installed on the upper frame 1a.
Inside a is a moving gear 8b that is moved up and down by the movement of the cable 6, and on the frame 8a is a rack 8c that is inclined so that the moving path of the moving gear 8b becomes narrower as it goes upward. A pin 8d is fixed on the opposite side to form a passage for the cable 6, and the cable 6 is sandwiched between the moving gear 8b and the pin 8d to stop its movement.

Note that FIG. 5b shows the stopper 8 with the pin 8d omitted.

In order to open the panel 5, lower the guide rails 3 and 4 toward the indoor side by the operation described below, and then remove the cable 6 from the stopper 8.
As shown in B and C, it moves downward sequentially from the lower panel 5.

At the position where the lowermost fixed panel 5' is arranged, the guide rails 3 and 4 are bent toward the indoor side,
As shown in the figure, the movable panels 5 are sequentially housed inside the fixed panel 5'.

To move the guide rail 4 downward, first,
The handle 11 is operated to rotate the camshaft 10, and the cam 9 fixed to the shaft 10 is rotationally moved from the chain line to the solid line in FIG.

Thus, the cam 9 engages with the guide rails 3 and 4 at the circumferential side at the position closest (lower) to the axis of the camshaft 10, which is its eccentric shaft, and moves the guide rails 3 and 4 downward as shown in the figure. to release the bonded state between the movable panel 5 placed on the guide rails 2 and 3 and the packing material 15.

That is, as the handle 11 is rotated, the cam 9 is rotated, and the position in contact with the guide rails 2 and 3 is lowered in the axial direction, and the movable panel 5 and the guide rails 2 and 3 are moved by their own weight. It is moved to the indoor side (see Figures 3 and 4).

At that time, the bearing 14' installed inside the bearing holder 14 is guided by the linear shaft 13', and the holder 14 is moved downward (toward the indoor side), and the guide rails 2 and 3 are connected to the lift frame 1.
Supported by 3.

After that, the rope 6 that is locked to the stopper 8
When pulled downward, the moving gear 8b is pulled downward,
The gear 8b moves downward along the rack 8c, and the locked state of the cable 6 is released.

Therefore, the movable panel 5 is moved by its own weight toward a lower position in the gradient direction, and when each panel is moved to the lower end, it is in a fully open state, and on the other hand,
By stopping the movement of the panel at an arbitrary position, the opening area of the canopy can be freely adjusted. It is something.

In addition, in order to stop the panel 5 halfway, move the moving gear 8b while pushing the cable 6 in the direction of the rack 8c.
This is done by bringing the gear 8b into contact with the gear 8b and moving the gear 8b upward due to the friction welding, and locking the cable 6 at the above-mentioned position.

Next, in order to shift from the open state to the closed state, contrary to the above, when the cable 6 is released from the locked state and the cable 6 is pulled downward, the movable panel 5 is attached to the cable 6. It is pulled and moved upward, and each panel 5 closes the opening.

Thereafter, the handle 11 is rotated to raise the guide rails 2 and 3 toward the outdoors and join them with the packing material 15, thereby transitioning the room into a sealed state.

In addition, if air is only to be taken in for ventilation, simply rotating the handle will create a gap between the packing material and the panel, and ventilation will be performed from that part.

In the above embodiment, the panel was opened and closed manually, but when the temperature and humidity are detected by a sensor and the preset conditions are met, the switch is turned on automatically. Therefore, current may flow to a separately arranged electric motor, and the panel may be opened and closed by the electric motor.

[Effects of the invention] The opening/closing device of the invention can manually move the movable panel up and down in the indoor/outdoor directions and up and down in the slope direction with one touch, and has excellent operability when opening and closing. Also, based on this idea, it is easy to add electric properties.

In addition, by minimizing the protrusion of each component toward the indoor side, the indoor space can be used effectively without waste.

Furthermore, when moving the panel, it can be done with a familiar operation like moving the blind up and down, making it an extremely practical idea.
