Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used for windows on side walls of livestock barns, etc.
Mainly related to curtain opening/closing devices for temperature control and ventilation control.

Currently, there are two types of curtain opening/closing devices that are installed on the side walls of breeding houses: an upper-opening lower-winding type and a lower-opening lower-winding type.

The lower-opening, lower-winding type curtain opening/closing device has a simple structure, and the curtain opening/closing operation is almost satisfactory without problems such as "sagging," but the upper-opening, lower-winding type curtain opening/closing device has a slightly more complicated structure. However, in terms of temperature and ventilation adjustment, prevention of wind and rain, etc., a roll-up type curtain opening/closing device with an upper opening is recommended. Since this is desirable, improvements to this method have been desired.

The present inventors have achieved the present invention as a result of research into the simplification, suitability, and ease of opening/closing operations of an upper opening/lower roll-up type curtain opening/closing device.

The present invention relates to a suspended curtain device with an upper opening and a lower winding type used in livestock barns, etc. The present invention relates to a curtain device that is removably fixed to the lower part of the livestock barn, etc., and is equipped with a rail that guides the curtain winding device up and down. A curtain whose lower edge is fixed to a curtain winding shaft whose one end is attached to a winding device so that it can be wound freely, and whose upper edge is fixed to a curtain support rod, and which can be attached and detached to a beam under the eaves of a livestock shed, etc. attached to a pulley of a pulley member suspended from the curtain support rod, one end of which is fixed to the curtain support rod, and the other end fixed to the counterweight member;
and an appropriate number of cable members provided at appropriate intervals, each having the same number and approximately the same length as the cable members, one end of which is fixed to each of the cable member fixing portions of the curtain support rod, so that the curtain can be It is made up of an appropriate number of annular bodies, each of which is housed and holds the curtain winding part from below, and whose other end is a string member fixed to each of the rope member fixing parts of the balanced weight member. The balance weight member is formed to be heavier than the total weight of the curtain support rod and the curtain, but lighter than the total weight of the total weight and the weight of the curtain winding shaft, and the balance weight member forms the lower part of the annular body. An upper-opening lower part of a livestock shed, etc., characterized in that a string member holds a curtain winding part from below, and the curtain is controlled up and down by operating a curtain winding device. This is a hanging type curtain opening/closing device.

In the present invention, the term "livestock shed, etc." refers to a breeding house for livestock, poultry, etc., and the lower part of the livestock house, etc. and the eave beam part of the livestock house, etc. refer to windows and other openings provided in the side walls of the livestock house, etc. Means the lower part of the lower edge and the upper part of the upper edge.
In addition, since the rope member is hung on a pulley and operated while holding the curtain suspended together with the string member, wire ropes, ropes, etc. are preferable. It is desirable to use a belt-like string in order to raise and lower the ring, and also to widen the distance between the annular bodies.
Further, the balanced weight member may be an independent weight provided at each joint between the cable member and the string member, but it is preferable to use a bar-shaped weight, such as an iron pipe, that connects each joint. preferable. In addition, each member, such as a cable member, a string member, and a balance weight member, can also be provided detachably as appropriate.

In the curtain device of the present invention, the pulley member is locked to a hook or the like at the top of the opening of a livestock barn, etc., the curtain winding shaft is positioned on the side of the lower edge of the opening, and the guide rail member is moved vertically. It is installed as follows. Then, by operating the curtain winding device to wind up or unwind the curtain, the upper part of the opening of the livestock pen, etc. is It controls opening and closing.

Next, embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows the curtain device of the present invention as seen from inside the building.
FIG. 2 shows a side view of the curtain device of the present invention, FIG. 3 shows a conventional curtain device as seen from inside the building, and FIG. 4 shows a side view of the conventional curtain device.

In the figure, 1 is a curtain of an appropriate size determined according to the size of the window of the breeding house, and a curtain support rod is provided at the upper edge, and a curtain winding shaft 2 is attached to the lower edge.
A curtain 2 for opening and closing a window is connected at one end to a winding device 11, and as the winding device 11 operates, a curtain winding shaft 3 winds up the curtain 1 from the bottom. is a curtain wound around a curtain winding shaft 2, and the wound portion is held from below by a belt-like string 5 connecting a curtain support rod 4 and an iron pipe for counterweight (balance weight member) 7. 4 is a support rod provided at the upper edge of the curtain, which is slightly longer than the length (width) of the curtain; 5 is a support rod whose upper end is fixed to the curtain support rod 4;
A belt-like string is provided by connecting the support rod 4 and the counterbalance weight member 7, each having the same length,
A suitable number of string members 6 are provided at appropriate intervals (preferably at equal intervals), and are wire ropes of the same length, one end of which is attached to the curtain support rod 4, and one end of the strip string 5 is fixed to the position. A steel cable (wire rope) that is fixed at the position where the other end of the belt-like string 5 is fixed to the counterweight iron pipe 7 and forms a ring-shaped body with the belt-like string 5; the above,
The annular body consisting of a band string 5 and a wire rope 6 is suspended by the wire rope 6 being secured to a hook provided on a beam 9 above the upper edge of the window of the breeding house via a pulley member 8. and the belt-like string 5
is wound around the curtain winding shaft 2.
Hold the curtain below the lower edge of the window and
An annular member 7 holds the curtain 1 so as to cover the window when the curtain is unfolded upward, and also operates the curtain 1 (curtain support rod 4) vertically according to the rotation of the curtain winding shaft 2. The annular member is provided with a curtain winding shaft that is heavier than the total weight of the curtain support rod 4 and the curtain 1 (including the rolled-up curtain portion 3) at a given curtain length, and that is heavier than the total weight of the curtain support rod 4 and the curtain 1 (including the rolled-up curtain portion 3). A balance weight member that is lighter than the total weight of 2 and has the above balance, and is an iron pipe for the balance weight to lubricate the opening and closing of the curtain. 8 is a wire rope pulley. 9 is an under eave. When the beam part, 10 is a floor sill part (lower side wall), 11 is a curtain winding device, and 12 is a rail for moving the curtain winding device, the cable member (wire rope) 6 and the string member (band-like string) 5 are stretched. Since the curtain winding section 3 may cause some inconvenience in lowering, the rail 13 indicates a curtain opening for vertically moving the curtain winding device 11 to which one end of the curtain winding shaft 2 is connected.

The horizontal length of the curtain 1 is determined depending on the size of the enclosure, but it can be extended up to about 100 m. Further, it is preferable that the annular body is provided at the left and right sides of the curtain support rod and the iron pipe (balanced weight member), and at an appropriate interval (preferably 1.8 to 3.6 m interval) between the both sides. . Although the string member 5 may be a wire rope, it is preferably in the form of a band in order to make contact with the curtain, and also in order to widen the installation interval of the annular bodies.

Since the curtain device of the present invention is configured as described above, when the handle of the curtain winding device 11 is operated in the curtain winding direction, the curtain 1 is wound around the lower curtain winding shaft, and the curtain 1 is wound around the lower curtain winding shaft. As the upper edge (curtain support rod 4) descends downward, the counterweight member 7 ascends upward, the curtain opening 13 (window opening) is enlarged, and the handle of the curtain winding device 11 is rotated When operated in the return direction, the balance weight member 7 moves down and the upper edge of the curtain (curtain support rod 4) rises, thereby reducing the curtain opening 13 (window opening).
This opening/closing operation of the curtain is performed when the balance weight member is heavier than the total weight of the curtain support rod 4 and the curtain 1 (including the rolled-up portion 3), and the total weight is the sum of the above-mentioned total weight and the curtain winding shaft 2. Since it is lighter than its weight and has a well-balanced structure, the curtains can be opened and closed smoothly without making any noise. In addition, even if the curtain, rope members, and string members elongate due to aging, the weight of the counterweight member and the curtain winding shaft absorbs the elongation, so there is no risk of the curtain sagging. In addition, even if the curtain winding section drops slightly due to the elongation of the rope and string members, the curtain winding device can be moved via the moving rail, so that the curtain winding shaft and the curtain winding device can be moved. It does not cause any inconvenience when connecting with.

The present invention having the above-mentioned configuration can reduce the labor required to open and close the curtain compared to the conventional upper-opening lower-rolling type curtain opening/closing device, does not cause the curtain to sag, and requires less installation work. It's easy.

The simplest conventional upper-opening, lower-winding type curtain opening/closing device is shown in FIGS. 3 and 4.

In the figure, 1 is the curtain, 2 is the curtain winding shaft, and 3
1 is the rolled-up part of the curtain, 4 is a curtain support rod, 11 is a curtain winding device, 13 is a curtain opening, 14 is a curtain hanging wire, 15 is a retainer for the curtain winding part, 16 is a pulley, and 17 is a curtain The traction wire 18 indicates the wire 17 winding drum.

The conventional curtain opening/closing device with the above configuration operates the winding device 11 and the 18 wire winding drums.
By winding or unwinding the curtain traction wire, the traction wire 17 and the curtain hanging wire 14 fixed to the curtain support rod 4 open and close the curtain 1 via the pulley 16 and are connected to the winding device 11. The curtain is opened and closed by winding up or unwinding the lower part of the curtain 1 on the curtain winding shaft 2, and the opening and closing of the curtain and the winding and unwinding of the curtain are linked. It is difficult to adjust the interlocking between the winding shafts, and the curtain sag due to aging of the wire. In addition, in order to prevent the winding part 3 of the curtain from falling, the winding part 3 is held by a metal fitting 15 fixed to the building wall, so the frictional resistance generated when opening and closing the curtain is significant, and the labor required to open and close it is large. It becomes.

It is extremely undesirable for curtains to sag, as this can lead to accumulation of dust, accumulation of rainwater and condensation water, and amplify flapping caused by wind, worsening the indoor environment and promoting deterioration of the curtain fabric. be. Further, in the present invention, unlike the case where the rolled up curtain (curtain winding section) 3 is held by a metal fitting 15 fixed to a building wall, the curtain winding and unwinding are respectively sent in the forward direction. Not only is this done together with the string member 5, but the weight of the curtain is substantially balanced with the balance weight member 7 via the pulley 8, so the effort required to open and close the curtain is extremely small. For example, curtain length 100
For M-class curtains, conventional curtain opening/closing devices required a pulling force of around 200 kg, but with the present invention, this can be reduced to about 1/10 or less. Since the present invention is suspended in a building, there is a risk that it may be turned over by strong winds, but this can be prevented by installing belts to prevent turning over, which is commonly practiced at present. It can be prevented.

According to the present invention, the curtain can not only be opened and closed easily with little effort and without causing the curtain to sag, but also the installation work can be done by installing the pulley member provided in the annular body on the upper part of the shed. This is extremely easy to do, as all you have to do is hang it up by hooking it to a hook.
