Description

[Detailed explanation of the invention] (Industrial application field) This invention allows easy remote control of openable windows in buildings, houses, large greenhouses, etc. that are particularly difficult to reach or reach. It relates to a window opening/closing device for opening and closing windows, and more specifically, it opens automatically by the action of a spring, etc., and stops properly in the fully open position.
This invention relates to a window opening/closing device that can be properly stopped in a fully closed position by rope operation.

(Prior art and its problems, etc.) For example, in the case of a greenhouse, the indoor temperature rises too much during the day, except during the coldest months, so it is necessary to release the trapped heat.

Therefore, in the case of vinyl greenhouses, it is common practice to roll up the vinyl sheet at the hem of the house as needed to improve ventilation.

However, similar measures cannot be taken in the case of glass greenhouses. Furthermore, it is natural that heat tends to accumulate in the ceiling of a greenhouse, and in order to effectively release this heat, it is recommended to install a skylight A as shown in FIG. 5, for example. Alternatively, it is better to install a gable window B to improve ventilation in the direction of the ridge, and a side window C is also useful.

However, since the skylight A and the gable window B are located at a high place and cannot be reached, a window opening/closing device is required to open and close them remotely. It would be better to have a window opening/closing device for side window C as well.

By the way, in the case of a greenhouse, the windows must be opened and closed at least twice in the morning and evening, so it is necessary to be convenient and inexpensive. It must also have a structure that will not flap around in the wind.

However, conventional window opening/closing devices, such as high-grade automatic devices used in buildings and ordinary houses, are too expensive and lack convenience and economy.

On the other hand, window opening/closing devices such as those conventionally used in greenhouses also have the disadvantage that they are not easy to operate and are not easy to operate, despite their relatively large structure.

(Purpose of the invention, technical problems to be solved) Therefore, the purpose of this invention is to have a simple structure, small size, light weight, and therefore low cost, excellent operability in opening/closing, and being able to be easily used remotely. It is an object of the present invention to provide a window opening/closing device having a configuration excellent in stability in a fully open state and a fully closed state.

(Structure of the invention, means for solving the problems) In order to achieve the above object, the window opening/closing device of this invention has, for example, a telescopic device that is freely extendable and retractable and that is constantly applied with an operating force (extension force) in the direction of extension by a spring or the like. One end of the operating rod is connected at one side edge to a rotatably supported movable window frame (for example, a casement window), and the other side is connected to, for example, a fixed window frame on the building side. A movable stopper is attached to one of the rod elements forming the operating rod, and the other rod element has a hooked portion on which the stopper is latched at a position corresponding to fully closing the movable window frame or at another predetermined position. , for example, a U-shaped recess, etc.
One or more are provided. Further, an operating rope connected to the stopper so as to be detachable from the hanging portion is disposed and hangs down from the free end of the movable window frame toward the building. In addition, as a closing means for holding the movable window frame in the closed position on the building side, for example, in a door stop, for example, a spring or the like is used to keep the movable window frame in a constant latching direction when the movable window frame is closed. A latching device is installed, and a release rope (or a rod or the like) for moving the latching device in the opposite direction is connected to the latching device, and is hung from the building side in line with the operating rope.

(Effect) In other words, the closed state of the movable window frame is self-retained by the latching device that is the closing means being latched onto the movable window frame, and even if it is blown by the wind, it will not flap around or open unexpectedly. Never.

When you want to open the window, pull the release rope and release the latch. Then, the movable window frame automatically opens as the operating rod extends due to the operating force in the extending direction of the operating rod. When the movable window frame reaches a preset fully open position, the stopper engages with the hooked portion and is self-retained. Therefore, the movable window frame is automatically and reliably fixed in the fully open position, and will not flap around even if it is fanned by the wind.

Next, when you want to close the window, pull the operating rope. Then, the stopper first comes off from the hooked part.
If the operating rope is subsequently pulled with a force greater than the operating force of the operating rod, the movable window frame can be closed by the operating rope. When the fully closed position is reached, the latch is engaged with the movable window frame, and the fully closed state is reliably maintained by itself.

As mentioned above, the purpose of opening and closing the window can be easily, quickly and reliably achieved by operating the rope, and the requirement for frequent opening and closing operations can be well met.

Furthermore, as long as two ropes are hung, the opening and closing operations of windows can be easily and reliably performed at any location and at any height, which is very convenient.

Furthermore, this window opening/closing device is relatively small and has a simple configuration, so it can be manufactured at low cost and is easy to use, making it suitable for use in greenhouses and the like.

(Example) FIGS. 1 to 4 show an example applied to the gable window B of the greenhouse shown in FIG. 5.

In the figure, 1 is the operating rod. This is two rod elements,
That is, it is constructed by fitting two steel pipes 1a and 1b, which have sufficiently large strength and rigidity and have different diameters, into a telescope so that they can be expanded and contracted. Both outer ends of the two pipes 1a and 1b are closed,
A long compression coil spring 2 is inserted into the hollow portion, and the coil spring 2 constantly applies an operating force in the direction of expansion. However, this is not limited to coil springs, as long as the same operating force can be applied.
Fluid pressure application means etc. may also be used.

A straight protrusion 3 with a constant height is provided on the outer periphery of the small diameter pipe 1b in the axial direction. On the other hand,
The large-diameter pipe 1a is provided with a slit 4 that allows the protrusion 3 to move forward and backward in its axial direction, and rotation between the pipes 1a and 1b is restricted by fitting them together.

The tip of the large diameter pipe 1a of the operating rod 1 is
A movable window frame 7 whose one side edge is rotatably supported by a hinge 5 to a sheet holding member 6 that is the frame of the greenhouse building.
It is rotatably supported by a bolt shaft 10 at a position relatively close to the tip of a substantially channel-shaped steel-shaped middle crosspiece 8 that forms a part of the shaft. The bolt shaft 10 is fixed with a nut 11 (FIG. 4).

On the other hand, a bracket 12 is fixed on the protrusion 3 of the small diameter pipe 1b at a position on the right side in FIG. It is rotatably supported at a relatively upper portion of the vertical beam 14. bolt shaft 13
is fixed with a nut 17 (Fig. 4).

The vertical beam 14 is fixed to the upper and lower sheet holding members 6 and 15 forming the window opening via an insert 16 by screwing or the like. The small diameter pipe 1b is connected through a slit window 18 formed in the vertical direction of the vertical beam 14 with a length that does not interfere with its rotational displacement.

The upper and lower sheet retainers 6 and 15 correspond to fixed window frames that form window openings, and are each firmly fixed to a pipe 19, which is the main aggregate of the greenhouse building, with connectors (not shown) or the like. . A vinyl sheet 20 serving as a greenhouse covering material is stretched using each of the sheet holding materials 6 and 15. Further, the lower sheet holding member 15 also serves as a so-called door stop, and the movable window frame 7 comes into contact with this (FIG. 3), resulting in a fully closed state.

In other words, the movable window frame 7 changes from the fully closed position where it hangs down vertically as shown in Figure 3, to the fully open position where it opens almost horizontally as shown in Figure 1. 1 opens with the extension of the operating rod 2 due to the operating force of the coil spring 2 built therein. Therefore, the strength of the coil spring 2 and the extension/contraction stroke of the operating rod 1 are configured to match the opening/closing specifications of the movable window frame 7.

Next, reference numeral 21 in the figure denotes a stopper 24 which is attached to a rib 22 projecting from the outer periphery of the large-diameter pipe 1a of the operating rod 1 so that it can be raised and lowered (rotatably) with a pin 23.
is a recessed portion formed in a substantially U-shape as a hooked portion in the protrusion 3 of the small diameter pipe 1b.

That is, the pin 2 provided on the free end side of the stopper 21
5 fits into the recessed part 24 (FIG. 1), and the fully open position of the movable window frame 7 is self-maintained. Therefore, the recessed part 24 is such that the small diameter pipe 1b is different from the large diameter pipe 1.
a to the fully open position of the movable window frame 7. However, the number of recessed portions 24 is not limited to one, and a plurality of recessed portions may be provided so as to define the degree of opening of each stage of the movable window frame 7. Also, Stoppa 21
is constantly biased by a torsion coil spring 26 in the locking direction in which the pin 25 rotates toward the recessed notch 24 . However, a configuration in which the force is similarly biased by a moment due to unbalanced weight may be used.

Therefore, as described above, when the operating rod 1 extends until the movable window frame 7 reaches its fully open position, the pin of the stopper 21 simultaneously fits into the recessed part 24.
As a result, the fully open position of the movable window frame 7 is automatically maintained by itself. Therefore, even if the movable window frame 7 is blown by the wind, it will not fluctuate and will remain stable.

Next, reference numeral 27 in the figure is an operating rope whose one end is connected to the pin 25 on the free end side of the stopper 21. The operating rope 27 is connected to a guide roll (or a simple pin may be used) 28 provided on the middle crosspiece 8 and a movable window frame 7 on the middle crosspiece 8 so as to be located almost directly above the stopper 21 in the fully open state shown in FIG. A guide roll (or a simple pin may be used) 29 provided near the free end of the greenhouse, and a vertical beam 14 on the side of the greenhouse building.
It hangs down into the greenhouse for a necessary and sufficient length via a guide roll 30 provided at the bottom of the greenhouse. 31 in Figure 4
is a window hole provided at the bottom of the vertical beam 14 for passing the operating rope 27 therethrough.

Therefore, when the operating rope 27 is strongly pulled in the fully open state shown in FIG.
direction), and the pin 25 is removed from the recessed notch 24 (FIG. 2). When the operating rope 27 is pulled more strongly, the tensile force G moves the movable window frame 7 in the counterclockwise direction (direction of arrow D) in FIG. 2 via the guide roll 29 provided on the free end side of the movable window frame 7. The movable window frame 7 is closed by acting as a rotational force for rotation and at the same time overcoming the operating force of the coil spring 2 to contract the operating rod 1 in the direction of arrow F.

Thus, by pulling the operating rope 27, the movable window frame 7 can be closed to the fully closed state in which it abuts the lower sheet holding member 15.

However, 32 in the figure is the vertical beam 14 on the side of the greenhouse building.
This is a latching tool as a closing means, which is rotatably installed at the lower part of the holder and is rotatable about a shaft 33. The hook 32
One end of a tension spring 34 is connected to the inner end of the tension spring 34, so that the latch 32 is always biased in the counterclockwise direction (latching direction) in FIGS. 1 and 2. The hanging tool 3
A chevron-shaped hook portion 32a is formed on the lower edge side of the tip of 2. The latching tool 32 projects outward from the building through a slit 35 formed at the bottom of the vertical beam 14, and its latching preparation position (posture) is defined by coming into contact with the lower edge of the slit 35. In the figure, reference numeral 36 denotes a release rope connected to the inner end of the hanging device 32 and suspended within the greenhouse for a required length.

On the other hand, a latching pin 37 is provided on the tip side of the middle crosspiece 8 that is integral with the movable window frame 7 and at a position corresponding to the latching tool 32 when the window is closed.

That is, when the operating rope 27 is pulled to bring the movable window frame 7 into the fully closed state as described above, the latching pin 36 simultaneously pushes up the hook portion 32a of the latching tool and sinks under the hook portion 32a, resulting in the latching state. Become.

That is, when the movable window frame 7 is in the fully closed state, the latching pin 3
6 is automatically self-retained and stabilized by being caught on the hook 32. Therefore, there is no possibility that the movable window frame 7 will fluctuate or fluctuate due to being fanned by the wind. However, the closing means is the hook 32.
Instead, the operating rope 27 may be tensioned and fixed in some way.

Note that when the release rope 36 is pulled, the latch 32 escapes from the latch pin 37 and comes off. Therefore, the movable window frame 7 is opened by the coil spring 2 built into the operating rod 1 as the operating rod 1 extends.
