Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a heating curtain that has a curtain body and a heater and performs heating by dissipating heat from the curtain body.

(Prior art) Generally, inside openings such as windows indoors, light shielding and
Curtains are installed for purposes such as cold protection and decoration, but in recent years, various heating curtains have been proposed in which linear or planar heaters are attached to the entire surface or interior of the curtain body. Development is underway.

While these heating curtains improve the insulation effect of wall materials, they also locally heat openings such as windows, which are relatively weak points in terms of insulation, and prevent cold air from entering the area. It has the function of heating the room at the same time. 2. It has the advantage of eliminating the need for a dedicated space for arranging heating equipment. Space-saving heating curtains based on such multiple functions are extremely promising as fixtures for indoor spaces in recent years, where various fixtures are arranged in a limited space, and further development is expected.

In addition, with the recent diversification of lifestyles, the decorative nature of indoor fixtures has become particularly important, and curtains are also being placed not only inside openings, but also inside walls, or as partitions between indoor spaces. Its use for various purposes is expanding.

(Problems to be Solved by the Invention) By the way, heating curtains have a structure in which heaters are attached to the entire surface of the curtain body.2.It is difficult to fold into a compact storage state, and storage performance is poor. The drawback was that it was unsuitable for use in the summer. Further, due to such poor storage properties, the use state is limited to only the unfolded state, so there is also a limit in decorativeness.

Furthermore, even if it were possible to realize a structure that allows the curtain to be stored, if the heater is placed in the stored state while it is still generating heat, the heater density will become extremely high and the curtain body will overheat, which is dangerous.

The present invention was proposed in order to solve the following two problems of the prior art, and its purpose is to provide a heating curtain with excellent storage and decorative properties.

It also improves safety by preventing the curtain body from overheating if it is accidentally stored without turning off the power.
The purpose is also to do something.

Furthermore, as with general heating equipment, one of the purposes is to improve heating efficiency.

[Structure of the Invention] (Means for Solving the Problems) A heating curtain according to the present invention includes a curtain body and a heater that is disposed on or inside the curtain body and generates heat when energized. It is characterized in that it is formed so that it can be wound, that the heater is arranged so as not to interfere with the winding of the curtain body, and that it has a winding means for winding the curtain body.

More specifically, when winding the upper end of the curtain body as the center of winding, the heater is placed on the lower part of the curtain body on the outer periphery side of the curtain body, rather than on the second part of the curtain body on the winding center side. It is desirable to arrange them so that the arrangement density is higher.

Further, it is desirable to provide a detection switch that detects the start of winding or the middle of winding of the curtain body and cuts off the power supply to the heater.

In particular, when the winding means has a winding core around which the curtain body is wound, the detection switch can be provided so as to be operated by pressing the winding core and the curtain body.

Furthermore, a high-emission material layer with high far-infrared radiation efficiency is provided on the side of the space to be heated in the curtain body, and a heat insulating material layer is provided on the opposite side, and a heater is placed between these high-emission material layers and the heat insulating material layer. This is desirable.

(Function) In the heating curtain of the present invention having the above-mentioned configuration, the curtain main body in which the heater is arranged can be wound by the winding means, so that it has excellent storage properties.

Since the curtain body can be wound in this way, it is also possible to use it in the same way as a normal curtain without using a heater, either in the rolled state or in the middle of winding, so the decorativeness is also improved. are doing.

Specifically, in a type of curtain that is wound around one end of the curtain body as the center of winding, the arrangement density of the heaters with respect to the curtain body is from one part on the winding center side to the outer circumference side of the winding. so that it gets higher towards the bottom which is
When a heater is installed, in addition to making it easier to wind the curtain body, it also heats the lower part of the room intensively, generating heat convection and making the room temperature more uniform. It becomes possible to perform indoor heating that is both comfortable for the body and highly efficient.

Furthermore, if a detection switch is provided that detects the winding of the curtain body and cuts off the power supply to the heater, safety can be improved because the heater does not continue to generate heat in the winding state.

Furthermore, if a high-emission material layer and a heat-insulating material layer are provided on both sides of the curtain body, and a heater is placed between them, the far-infrared rays emitted from the heater will be efficiently radiated into the space to be heated by the high-emission material layer. At the same time, the insulation layer can prevent heat radiation to the space on the opposite side, which is not to be heated, so the radiation from the heater can be effectively used.
Highly efficient heating can be performed.

(Example) An example of a heating curtain according to the present invention will be specifically described below with reference to FIGS. 1 to 5.

First, FIG. 1 is a perspective view showing the entire heating curtain.

As shown in FIG. 1, the curtain body 1 is attached at its upper end to a rotating rod (winding core) 3 rotatably fixed to a support bracket 2, and is wound by rotating the rotating rod 3 in one direction. ”It's starting to get worse. This rotating rod 3 is urged in the winding direction by an elastic member (not shown), and is fixed by a locking device (also not shown) when no external force is applied.

On the other hand, a support member 4 is attached to the lower part of the curtain body 1, and a puller 5 is attached to the center thereof. When the lock is released and the curtain body 1 is pulled down and unfolded, and when the puller 5 stops being pulled down (with a predetermined force), the locking device is activated and the curtain body 1 is pulled down. It is designed to remain fixed in its current state.

Furthermore, if the pull handle 5 is released slightly after releasing the locking device by slightly pulling down the pull handle 5, the rotating rod 3 will rotate in the winding direction due to the biasing force of the elastic member, and the curtain body 1 will be rotated in the winding direction. It is now possible to Further, the winding structure using an elastic member and a locking device as described below is a well-known technique.

Further, a connector 6 is provided at the lower right end of the curtain body 1, and is connected to a connector 8 provided at one end of a power cord 7. A power plug 9 connected to an AC power source is provided at the other end of the power cord 7. Furthermore, 10 in the figure is a controller provided in the middle of the power cord 7, and is a device for controlling the temperature of the heater, which will be described later.

Next, FIG. 2 is a front perspective view showing the arrangement pattern of the lids 11 with respect to the curtain body 1. As shown in FIG.

As shown in FIG. 2, the heaters 11 are arranged in such a manner that their horizontally elongated portions are lined up in multiple stages below the heater 11. More specifically, the upper end (which is the center end of the winding of the curtain body 1)
An interval of dimension n+ is provided between line A) and the second-most stage (line B) of the heater 11, and this second-most stage (line B) is provided with an interval of dimension n+.
The arrangement interval from line B) to the fifth stage (line C) is a dimension 2 smaller than the dimension 1, and the position of this fifth stage (line C) is the same as that of the curtain body 1. In addition, the spacing from the fifth tier (line C) to the bottom tier and the spacing between the bottom tier and the lower end (line D), which is the outer circumferential edge of the curtain body 1, are determined according to the dimensions. 2
It is said to be the moon law Mata 3, which is even smaller than the moon. That is,
In this embodiment, the leaves 11 are arranged such that the arrangement density at the lower part of the curtain body 1, which is the outer circumferential side of the winding, is higher than at the upper part of the curtain body 1, which is the winding center side. In this case, the dimension 1+ of the portion of one end of the curtain body Ll where the heater 11 is not disposed is at least the circumferential dimension of the rotating rod 3.

Both ends of the heater 11 arranged as described below are connected to a connector 6 provided at the lower right end of the curtain body 1, and via this connector 6, as shown in FIG. , is connected to a power cord 7, and is supplied with power from an external power source.

Next, FIGS. 3 and 4 are enlarged sectional views showing the rotating rod 3 and the upper end portion of the curtain body 1 attached thereto.

As shown in FIGS. 3 and 4, the rotating rod 3 is provided with a detection switch 12 that detects the start of winding the curtain body 1 and cuts off power to the heater. This detection switch 12 has a fixed contact plate 13 fixed to the rotating rod 3, and a movable contact plate 14 provided so as to be able to contact and separate from the fixed contact plate 13. The plate 14 is integrally provided with a pressed protrusion 15 that is mechanically pressed by pressing the curtain body 1. This pressed projection 15 is normally held in a position protruding from the surface of the rotating rod 3 as shown in FIG. 3 by the urging force of an elastic member 16 provided between it and the fixed contact plate 13. It looks like this. In this case, the movable contact plate 14 contacts the fixed contact plate 13, and both are kept in an energized state (non-detection state). And, as shown in Figure 4,
When the curtain body 1 begins to be wound around the rotating rod 3, the pressed protrusion 15 is pressed by the curtain body 1 and pushed into the rotating rod 3 against the biasing force of the elastic member 16, thereby making it movable. The contact plate 14 is the fixed contact plate 13
It is designed to move from the position to the position where it is released (winding detection state). When such winding is detected, the detection switch 12 sends a winding detection signal to the external controller 10 via a signal path (not shown) to cut off the power supply.

Moreover, FIG. 5 is an enlarged sectional view of the curtain body 1,
The front side of the curtain body 1, that is, the space to be heated Sl
On the side, a curtain fabric 17 and a far-infrared high-emission fabric (high-emission material layer) 18 with high far-infrared radiation efficiency are placed overlapping on the front and back, and the back side of the curtain body 1, that is, the non-heating space S2 side. A highly insulating felt (insulating material layer) 19 is disposed on the felt 19, and an aluminum foil 20 and a lining 21 are sequentially overlaid on the surface of the felt 19.

And between the far-infrared high radiation cloth 18 and the felt 19,
A heater 11 is arranged. This heater 11 is a known linear heater made of copper wire coated with vinyl chloride. Note that these components of the curtain body 1, that is, the curtain fabric 17, the far-infrared high radiation cloth 18, the felt 19, the aluminum foil 20, the lining 21, and the heater 11 are bonded together.

The operation of this embodiment having the above configuration is as follows.

First, during heating, as shown in FIGS. 2 and 4, with the curtain body 1 in the fully unfolded state, connect the connector 8 of the power cord 7 to the connector 6 as shown in FIG. At the same time, by connecting the power plug 9 of the power cord 7 to an AC power source, the heater 11 is energized and starts generating heat.

The heat generated by the heater 1 radiates heat from the curtain body, warming the surrounding space.

In this case, in particular, in this embodiment, as shown in FIG. 2, the arrangement density of the heaters 11 below the curtain body 1 is high, so that the lower part of the room is heated intensively, thereby reducing heat convection. By generating heat, it is possible to equalize the indoor temperature, which is comfortable for the body and also leads to improvements in heating efficiency.

In addition, in this embodiment, as shown in FIG. 5, far-infrared high radiation cloth 18 and felt 19 are provided on both sides of the curtain body 1, and the heater 11 is placed between them, so that the radiation from the heater 11 is Far infrared rays can be efficiently radiated to the heating target space S1 by the far infrared high radiation cloth 18, and heat radiation to the non-heating target space S2 which is not to be heated can be prevented by the highly insulating felt 19. Therefore, by effectively utilizing the radiation from the heater 11,
This has the advantage of increasing heating efficiency.

Furthermore, in this embodiment, since the aluminum foil 20 is provided on the surface of the felt 19, the far-infrared radiation transmitted through the felt 19 can be reflected by this aluminum foil 20 toward the space Sl to be heated. The effect of preventing heat radiation to the space S2 is further improved.

On the other hand, when winding up the curtain body 1 in the non-heating state, disconnect the power cord 7, pull down the pull handle 5 slightly to release the locking device (not shown) on the rotating rod 3, and then pull it immediately. If you let go of hand 5, the rotating rod 3 will
The curtain main body 1- is rolled up by rotating in the winding direction due to the biasing force of an elastic member (not shown).

In this case, depending on the arrangement of the heater 11, the curtain body 1
However, in this embodiment, by arranging the heaters 11 as described above, the curtain body 1 can be easily and smoothly rolled up.

That is, at the start of winding, since the heater-free part of one end of the curtain body 1 (between line AB in FIG. 2) is larger than the circumferential dimension of the rotating rod 3, the winding must be completed at least once. , it can be rolled smoothly like a normal curtain without a heater. After this winding, even when the heater 11 reaches the second most stage (line B in Figure 2), the winding diameter remains small because the amount of winding is small; Since it is arranged along the horizontal direction, that is, along the winding axis direction, winding is easy. In particular, in this embodiment, the portions wound on the center side of the winding where the winding diameter is small, that is, from the second most stage of the heater 11 (line B in FIG. 2) to the fifth stage of the heater 11 (the second Up to line C) in the figure, the arrangement density of the heaters 11 is relatively low, making winding even easier. Note that the part further below this, that is, from the fifth stage of the heater 11 (line C in Figure 2) to the lower end of the curtain body 1 (second stage)
Although the arrangement density of the heaters 11 is high up to line D) in the figure, there is no problem because this part is wound on the outer circumferential side of the winding where the winding diameter is relatively large.

Therefore, in this embodiment, the curtain body 1 in which the heater 11 is disposed can be rolled up by the winding means, so that the curtain body 1 can be easily stored. Since the curtain body 1 can be rolled in this way, it can be used in the same way as a normal curtain without using a heater, either in the rolled state or in the middle of being rolled, so the decorativeness is also improved. I'm doing it.

By the way, the operator forgot to disconnect the power cord 7 and performed the following operation with the power cord 7 still connected, that is, with the heater 11 still generating heat. In this case, the heaters 11 are concentrated in the winding portion, but the detection switch 12 operates to cut off the power supply, thereby preventing the curtain body 1 from overheating. That is, in the unfolded state of the curtain body 1,
As shown in FIG. 3, the pressed protrusion 15 of the detection switch 12 protruding from the surface of the rotating rod 3 moves as shown in FIG. , is pressed by the curtain body 1 and pushed into the rotating rod 3 against the (=j force) of the elastic part 16. As a result, the movable contact plate 14, which is fixed integrally with the pressed projection 15, comes into fixed contact. The position where it separates from plates 1 and 3 (
The winding is detected in the winding detection state), and this winding detection signal is sent from the detection switch 12 to an external controller 0 via a signal path (not shown), and the controller 10 1] Cut off the power supply to.

In this way, in this embodiment, even if the operator accidentally unwinds the curtain body 1 while the heater 11 is still generating heat, the detection switch 12 is mechanically operated and the controller Since the power supply is cut off by 10, overheating of the curtain body 1 can be reliably prevented, resulting in excellent safety.

In addition, when unfolding the curtain body 1 that has been rolled up by the second winding operation, if the puller 5 is pulled down with a predetermined force, the lock will be released and the curtain body 1 will open. be lowered. Then, if you stop pulling down at the desired point,
The locking device operates and the curtain body 1 is fixed in the desired unfolded state.

Furthermore, such a state where the curtain body 1 is in the middle of being unfolded,
That is, even if the operator accidentally connects the power cord 7 and attempts to start heating while a part of the curtain body 1 is wound around the rotating rod 3, the detection switch 12 or
Since it is in the winding detection state as shown in FIG. 4, the power supply is kept cut off by the controller [0] and the heater 11 does not generate heat, so that the curtain body 1 is in the winding detection state as shown in FIG. It can be used to reliably prevent overheating.

Note that the present invention is not limited to the above embodiments,
For example, the arrangement of the heater 11 can be selected as appropriate. 6th
The figure shows an embodiment in which the heater 11 is arranged only in the lower part of the curtain body 1. In the embodiment shown in Fig. 6, since the heater 11 is not arranged in the second part of the curtain body 1, it is easier to wind the curtain, and since it is completely heated at the bottom, it is more comfortable for the body. And it's also efficient.

Moreover, the specific materials of the heater 11 and each component of the curtain body 1 can be selected as appropriate; for example, the heat insulating material is not limited to felt.

Furthermore, the winding configuration of the curtain body 1 used in the present invention can be selected as appropriate, and especially for large curtains, a configuration using an electric motor-driven winding mechanism instead of a manual winding mechanism is conceivable.

On the other hand, the configuration of the detection switch can be changed as appropriate, and it is also possible to have a single configuration in which a similar detection switch is provided on the curtain side. It is also possible. For example, in the embodiment shown in FIG. 1, an optical sensor may be provided on the support bracket 2 that supports the curtain body 1 to detect the displacement of the winding diameter of the rotating rod.

[Effects of the Invention] As explained above, in the present invention, the curtain body is formed to be windable, the heater is arranged so as not to hinder the winding of the curtain body, and the curtain body is wound. By providing a winding means for this purpose, the curtain body on which the heater is arranged can be rolled, and a roll-type heating curtain with excellent storage and decorative properties can be provided.

In particular, in a type of curtain that is rolled up with the second part of the curtain body as the center of winding, if the heaters are arranged so that the arrangement density increases toward the bottom of the curtain body, the winding of the curtain body In addition to this, it is possible to perform heating with emphasis on the lower part, which makes it possible to perform indoor heating that is both comfortable for the body and highly efficient.

Furthermore, if a detection switch is provided that detects the winding of the curtain body and cuts off the power supply to the heater, the heater will not generate heat in the winding state, so safety can be improved.

Furthermore, if a high radiation material layer and a heat insulating material layer are provided on both sides of the curtain body and a heater is placed between these layers, the far infrared rays emitted from the curtain can be efficiently heated into the space to be heated by the high radiation material layer. In addition to being able to radiate heat to the space on the opposite side, which is not to be heated, the heat insulating material layer can prevent heat radiation to the space on the opposite side, which is not the heating target, so the radiation from the heater can be used effectively.
This can greatly contribute to improving heating efficiency.
