Description

[Detailed description of the invention] (Industrial application field) BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical window installed in a building.

(Prior art) As a first conventional example of a sliding window, one of the upper and lower shojis is fixed to the window frame, the other shoji is attached to the window frame so that it can move up and down, and the movable shoji is pushed up by hand. Is there something that opens or closes?

Further, as a second conventional example, there is a structure in which a movable shoji is biased in the pulling direction by a mainspring or a coil spring.

In addition, as a third conventional example, two shoji (indoor and outdoor) are attached to the window frame so that they can move up and down, racks are attached to the vertical bars of each of the two movable shoji, and pinions that engage with both racks are attached to the window frame. Some shojis are constructed so that when one shoji is moved up (moved down), the other shoji will also be moved down (up).

(Problem to be Solved by the Invention) However, among the above-mentioned conventional lift-down windows, the first conventional example has to open and close the shoji against the weight of the shoji, so it is not easy to open and close the shoji. The problem is that there isn't one.

In addition, in the second conventional example, although the effort required to open and close the shoji is reduced, as the shoji is pulled upward, the pulling force exerted by the mainspring or coil spring decreases, so it is not easy to pull the shoji upward. There was a problem that it wasn't there.

In addition, the third conventional example has the advantage that it is possible to balance the indoor and outdoor shoji, so the shoji can be easily raised and lowered regardless of the vertical position of the shoji, but the window The fully open position is limited to the case where the two shoji are at the center in the vertical direction, and there is a problem in that a request to open only the upper part or the lower part cannot be met.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a raising/lowering window in which the shoji can be easily moved up and down regardless of its vertical position, and both indoor and outdoor shoji can be raised and lowered independently. .

(Means for Solving the Problems) In order to achieve the above-mentioned object, the lift/lower window of the present invention has an indoor shoji and an outdoor shoji mounted inside the window frame so as to be movable up and down, and bearings mounted on the upper frame of the window frame. The first and second rotating shafts are installed in parallel through the shoji, a drum for winding the support material for supporting the indoor shoji is attached to the portion of the first rotating shaft corresponding to both sides of the shoji, and the second rotating shaft is connected to the second rotating shaft. Drums for winding the supporting material that supports the outdoor shoji are attached to parts corresponding to both sides of the shoji, and a leaf spring bent to a predetermined curvature is attached to one of the two drums to apply force in the winding direction. The winding-side drum of a two-volume balancer for indoor shojis is rotatably fitted to the second rotating shaft, and the feeding-side drum is fixed and installed on the first rotating shaft. , 2 for outdoor shoji with the same configuration as above
The winding balancer is characterized in that the drum on the winding side is rotatably fitted to the first rotating shaft, and the drum on the feeding side is fixedly attached to the second rotating shaft.

In addition, in one aspect of the present invention, the first aspect of the present invention. Each of the second rotating shafts has a length corresponding to almost the entire width of the window frame, and a wire rope is used as the supporting material for supporting the shoji, and the wire rope is wound around a drum attached to one end of the rotating shaft. A sheave attached to one side of the shoji, a sheave attached to the upper corner of one of the window frames, and a sheave attached to the upper corner of the other window frame, and a sheave attached to the upper corner of the other window frame. A structure is adopted in which the sheave is attached to the side and wrapped around a drum attached to the other end of the rotating shaft.

In addition, the first and second rotation axes are each divided into left and right halves,
A structure can be adopted in which supporting members are independently provided on the left and right sides in correspondence with each rotating shaft.

(Function) The two-wound balancer used in the present invention is one in which a leaf spring bent at a predetermined curvature is wound around two trams, and the direction in which the bending direction of the leaf spring matches the curved surface of the drum with respect to one drum. The coil is wound around the other drum so that the bending direction of the leaf spring is opposite to the curved surface of the drum, and the force of the leaf spring generates a rotational force in the winding direction on one drum. Therefore, by freely fitting the drum that generates force in the winding direction onto one rotating shaft and fixing the other drum to the other rotating shaft, the rotational force is applied to the rotating shaft to which the stationary drum is attached. By attaching a drum wrapped with wire rope for supporting the shoji to both ends of the rotating shaft, a force to pull up the shoji can be applied, and that force is applied to the drum of the leaf spring. Since it occurs between the wound part and the straight part, it is almost constant regardless of the position of the wire rope, etc., on the drum.

In addition, by using a structure in which the rotating shaft is connected via a sheave, which is a wire rope wound around the drums at both ends, it is possible to eliminate obstacles.
When either the left or right side of the shoji tries to go down, the tension on the wire rope on that side decreases and is wound onto the other side, so the heights of the left and right sides of the shoji are automatically balanced.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view of an embodiment of the lift-down window according to the present invention, seen from the indoor side, and the window frame l installed in the opening of the building consists of an upper frame 2 and a lower frame 3 made of extruded aluminum shapes or the like.
and left and right vertical frames 4.4. Reference numeral 5 denotes an indoor shoji, and 6 an outdoor shoji. These are made of a panel 9 within a rectangular frame formed by upper and lower horizontal bars 7, 7 and left and right vertical bars 8, 8 made of the extruded shapes or the like. By fitting the left and right vertical bars 8.8 into the grooves to and io provided in the left and right vertical frames 4.4 of the window frame 1, the window frame l
It is attached so that it can move up and down. In addition, a bracket 12 is attached to the upper part of each shoji 5.6 between the two sides using screws 11, etc., a roller 13 is attached to the bracket 12, and the roller 13 is brought into rolling contact with the fTI 110. The aim is to smooth the vertical movement of the shoji 5.6.

A support device 14 for the shoji 5, 6 is attached to the upper frame 2 of the window frame 1. As shown in the plan view of FIG. 2 and the front view from the indoor side of FIG. As shown in FIG. 4, which is a left side view of FIG. 3, the screws 17 are inserted into the holes 16 and screwed into the nuts 18 attached to the upper frame 2, so that the left and right brackets 15.
15 is fixed to the upper frame 2, and both left and right ends are supported by bearings 19 attached to the left and right brackets 15.
0 and the second rotating shaft 21 are installed in parallel. Further, an intermediate bearing 24 is provided at the intermediate portion of a frame 23 whose both ends are fixed to the bracket 15.15 with screws 22 (see FIG. 4), and the rotating shaft 20.21 is supported at the intermediate portion by the intermediate bearing 24. The distance between the rotating shafts 20 and 21 is maintained constant.

These first. At both ends of the second rotating shaft 20.21, trams 27 are wound with wire ropes 25, 26 as supporting materials for supporting the indoor shoji 5 and the outdoor shoji 6, respectively.
．． 28 is installed. The wire rope 25 wound around the drum 27 connects to the sheave 29 attached to the bracket 12 on one side upper part of the shoji 5 and the upper corner of one of the window frames 1 (in this embodiment, the bracket 15 with the bearing 19 attached). and a sheave 31 attached to the other upper corner of the window frame 1.

The shoji 5 is wound around a tram 27 attached to the other end of the rotating shaft 20 by wrapping it around a sheave 32 attached to the bracket 12 on the upper part of the other side of the shoji. 1. For example, when the left side of FIG. 3 goes down, the tension on the left side of the wire rope 25 decreases,
Since it is pulled to the right, the left side is pulled up and the right side is lowered, which is automatically corrected, so it is possible to balance the left and right sides, and it is possible to keep the shoji 5.6 horizontal at all times. The wire rope 26 supporting the outdoor shoji 6 is also hooked with a similar wire.

In Figures 1 to 3, reference numerals 33 and 34 designate two-turn palancers that apply rotational force in the direction of pulling up the indoor shoji 5.6 to the first and second rotating shafts 20 and 21, respectively; As shown in FIG. 5, the two-volume balancer 33 attaches a leaf spring 35 bent to a predetermined curvature (a indicates a part of its original contracted form) to one tram 36. The leaf spring 35 is wound so as to apply a force in the winding direction (that is, in the direction of further contraction), and one end of the leaf spring 35 is connected to the drum 36 by a wire (not shown), and the other end is connected to the other tram 37.
A bushing 40 is connected by a thread 38 and the winding side drum 36 is fixed to the second rotating shaft 21 by a pin 39.
A drum guide 41 (see FIGS. 2 and 3) is fixed to both sides of the drum 36 of the rotating shaft 21, and the tram 37 on the feeding side is screwed onto the first rotating shaft 20. 42
It is fixed by On the contrary, the two-volume palancer 34 that supports the outdoor shoji 6 supports the winding-side drum 36 as shown in FIG. The bushing 40 is fixed to the first rotating shaft 20 with a stop pin 39, and the drum 37 on the feeding side is fixed to the second rotating shaft 21 with a screw 42.

In such a configuration, as shown in FIGS. 5 and 6, the first and second rotating shafts 20.21 are subjected to tension forces indicated by arrows c and d due to the contraction force of the leaf spring 35. This tension acts as a force to rotate the tram 27 in the direction of pulling up the wire ropes 25, 26 shown in FIG. For example, if the weight of the shoji 5.6 is 8 kg, the left and right sheaves 29 are loaded with half the weight of 4 kg, and the wire ropes 25 and 26 are loaded with a weight of 2 kg, which is halved by the sheave 29. Tension acts. Since the rotating shaft 20.21 is provided with 28 parallans 33.34, 4 pieces for each shoji 5.6, a tension of 1 kg is generated in each 2-roll parancer 33.34. By using the shoji 5.6, the weight of the shoji 5.6 is offset by these two-volume balancer 33.34, and +S 5.6
．． 6 can be raised and lowered easily. Further, due to the resistance of the vertical movement of the shoji 5.6, it is possible to maintain the shoji 5.6 at an arbitrary height.

The present invention has been described above with reference to examples, but when carrying out the present invention, as shown in FIGS. 7 and 8, the first and second
The rotating shaft of is divided into left and right halves like 20A, 20B, 21A, and 21B, respectively, and the abutting part in the center is the bearing 2.
4A, and the wire ropes may also be divided into left and right parts such as 25A, 25B, 26A, and 26B. According to this structure, when maintenance and inspection are performed, the rotating shafts 20A, 20B, and 21A , 21B are easier to remove, and the left and right rotating shafts 20A, 2OB, 21A
Since the wire ropes 25A, 25B, 26A, and 26B rotate independently, only slack occurs in the wire ropes 25A, 25B, 26A, and 26B.

In addition, various changes and additions may be made to the specific shapes, structures, etc. of window frames, shoji screens, two-volume balancers, shoji support materials, support material winding drums, etc., without departing from the gist of the present invention. is possible.

(Effect of the invention) According to claim 1, the shoji is supported with the weight of the shoji offset regardless of the vertical position of the shoji due to the action of the two-volume balancer, so that the shoji can be easily moved over its entire vertical range. It is possible to operate it up and down. In addition, since a two-volume balancer is provided for each of the indoor and outdoor shoji, each shoji can be raised and lowered independently, allowing the shoji to be opened and closed in any desired posture. In addition, the 2-volume balancer is
It consists of a compactly wound leaf spring around a drum, and since multiple two-wound balancers can be placed on the shaft to concentrate the spring force, it can be stored compactly in the upper frame of the window frame. This makes it possible to install it in a narrow space.

According to claim 2, since the robes wound around the left and right drums are connected, the heights of the left and right sides of the shoji are automatically balanced.
You can move the shoji up and down smoothly without any rattling.

According to claim 3, one rotation axis is divided into left and right halves, and
Since the left and right supporting members are provided independently, it is easy to remove the rotating shaft during maintenance and inspection, and since the left and right rotating shafts rotate independently, there is no slack in the supporting members.
