Description

[0001] The present invention relates to a length-adjustable light shelf,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a light shelf capable of adjusting the width thereof, and more particularly, to a light shelf capable of adjusting the width of the light shelf which is stacked or unfolded in a sliding manner.

Recently, as the level of culture has been improved, the demand for quality improvement of the architectural space is increasing. As one of them, a technique for introducing natural light into a room has been developed. When natural light is introduced into a room, not only energy can be saved, but also a bright and pleasant indoor environment can be provided. This not only improves the living efficiency of residents, but also positively affects residents with psychological and physiological effects.

In order to introduce natural light into the interior space, conventionally, a window was installed at a necessary place in the building to allow natural light to enter the interior space. When the natural light is introduced into the indoor space through the window, the daylight illuminance near the window increases, while the daylight illuminance at the window and the distant place is low, resulting in an imbalance.

A light shelf is used to solve the problem that occurs when natural light enters the indoor space through the window only. The light shelf refers to a shelf-like device for reflecting the natural light introduced into the room to the ceiling for use as room lighting. Such a light shelf can be classified into an indoor light shelf and an outdoor light shelf depending on the installation place.

Of these, the outdoor type light shelf can introduce more natural light into the interior of the building, but it has the disadvantage of damaging the view. Especially, at nighttime and at low weather conditions, the light shelf can not play a role and can only damage the view.

In addition, if the light shelf is installed in a high-rise building and the environment receives high wind pressure, there is a risk of breakage and it is necessary to remove it. However, the outdoor light shelf has a problem that such an operation is not easy.

The length-adjustable light shelf 30 according to the present invention adjusts the overall length thereof so that the user can arbitrarily adjust the amount of light entering the room. To this end, the present invention has a structure in which a plurality of light shelves 30 are formed, and the total length of the light shelves 30 is adjusted while being stacked or unfolded or laminated again. Hereinafter, the configuration of the present invention will be described. For reference, reference numeral 'I' denotes the indoor side and 'O' denotes the outdoor side with reference to the window 10 '.

The length-adjustable light shelf (hereinafter referred to as' light shelf 30 ') of the present invention is installed in a window 10'. More precisely, the light shelf 30 can be installed in the window frame 10 surrounding the window 10 'or the window 10'. In this embodiment, the main plate 30 ', which constitutes the light shelf 30, Is fixed to the window frame 10. The main plate 30 'may be fixed to the window 10' instead of the window frame 10. In this case, the main plate 30 'may be fixed by using the magnetic force of a separate fastening means (not shown) ') May be fixed.

As shown in FIG. 1, the optical shelf 30 is formed by stacking a plurality of unit optical shelves. Here, the unit optical shelf is formed in a thin plate shape, which is rectangular in this embodiment. The unit light shelf may be made of a material having light weight and high strength, for example, aluminum or high strength resin. The shape of the unit light beam half is not necessarily limited to a rectangular shape, and may be made of a flexible material. In addition, the length and width of the unit light beam need not be specified, and can have various lengths and widths.

A reflective surface (32) is formed on an outer surface of the unit light ray half. The reflective surface 32 is a portion that substantially reflects sunlight and is treated with a glossy finish. However, a stain pattern may be formed on the ceiling of the room due to the stain of the reflection surface 32 or the contamination due to the foreign substance, so that it may be finished with a prismatic film.

The unit optical lathe is composed of a main plate 30 'and a lamination plate 31. Both the main plate 30 'and the laminating plate 31 constitute a unit optical lathe and may have the same shape. The main plate 30 'is fixed to the window frame 10 and the lamination plates 31 are formed of a plurality of pieces and are spread or laminated in a direction away from the main plate 30'. FIG. 1 shows a state in which all of the lamination plates 31 are laminated and positioned below the main plate 30 ', and FIG. 2 shows a state in which the lamination plate 31 is completely unfolded.

A reflective surface 32 is provided on the upper surface of the main plate 30 'and the laminating plate 31. Accordingly, when the main plate 30 'and the laminating plate 31 are unfolded, the increased reflecting surface 32 allows the natural light to sufficiently flow into the room. The reflective surface 32 may be formed of a separate film detachably attachable to the main plate 30 'and the laminating plate 31. In this case, only the contaminated reflecting surface 32 can be easily replaced.

Only the main plate 30 'is fixed to the window 10' or the window frame 10, and the lamination plate 31 is fixed to the window frame 10 '. The main plate 30' and the lamination plate 31 have substantially the same shape, Can be unfolded in a direction away from the main plate 30 '. More precisely, the lamination plates 31 are composed of a plurality of units, each of which has a structure in which they are stacked on each other and unfolded or laminated again. In this embodiment, the main plate 30 'is fixed to the left end 11 of the window frame 10.

The state in which the plurality of lamination plates 31 are fully opened can be seen in Fig. When the lamination plates 31 are completely unfolded as described above, the total length becomes the maximum, and the natural light can flow into the room to the maximum. Since the degree of spreading of the lamination plate 31 is adjusted, the overall length is adjustable. Therefore, the user can adjust the amount of natural light flowing into the room by controlling the degree of spreading of the lamination plate 31. [

In the present invention, the lamination plate 31 moves along the outer surface of the window 10 '. When the lamination plate 31 is unfolded, it does not protrude in the direction away from the window 10 'but moves in a state of being in close contact with the outer surface of the window 10'. Accordingly, one side of the lamination plate 31 is supported by the window 10 'so that it can be relatively stably supported, and the torque applied to the main plate 30', as compared with that projected forward from the window 10 ' It is easy to install. Reference numerals 31a to 31j denote lamination plates stacked upward from the lamination plate at the lowermost end.

Referring to FIG. 4, there is shown a structure for smoothly performing a process of sequentially stacking and re-folding the lamination plates 31 to each other. That is, at least one of the main plate 30 'and the lamination plate 31 is provided with a plurality of moving wheels 40 for rotating and moving in a process of sequentially stacking the plurality of lamination plates 31 . The moving wheels 40 are provided between the laminating plates 31 and between the laminating plate 31 and the main plate 30 'so as to smoothly move while rotating in the course of their unfolding. 4 is a sectional view taken in the direction of arrow 2 in Fig.

4, the moving wheel 40 is installed in the rotating space 35 inside the laminating plate 31. In this case, So as to assist the movement of the lamination plate 31 while rotating along the rotation space 35. 4, the rotation axis of the moving wheel 40 extends in the vertical direction, that is, in the direction in which the lamination plates 31 are stacked. At both ends of the rotating shaft, there are a pair of wheels that are actually rotated, and the pair of wheels are located in different lamination plates 31, that is, the upper lamination plate 31b and the lower lamination plate 31a , And the two lamination plates (31) rotate in the relative movement.

In this embodiment, the rotating space 35 and the moving wheel 40 are provided at both ends of the lamination plate 31 and the main plate 30 ', but the present invention is not necessarily limited to this, Three or more plates 31 may be provided along the width direction of the plate 31, or only one plate 31 may be provided. The movement wheel 40 is not necessarily provided in the rotation space 35 but may be rotated in close contact with the outer surface of the neighboring main plate 30 'or the lamination plate 31.

On the other hand, Fig. 5 shows another embodiment of the mobile wheel 40. Fig. 5, there is a rotating space 35 along the longitudinal direction of the inner lamination plate 31 of the lamination plate 31, and there is a moving wheel 40 there. The moving wheel 40 is installed on a relatively lower lamination plate 31a and is protruded upward and inserted into the rotating space 35 of the uppermost lamination plate 31b. Therefore, in the process of moving in the direction in which the lower lamination plate 31a is spread (in the direction of arrow 4 in Fig. 5), the mobile wheel 40 rotates in one direction (the direction of arrow 5 in Fig. In the embodiment shown in Fig. 5, the rotation axis of the mobile wheel 40 extends in the left-right direction, that is, in the width direction of the lamination plate 31. [

At one end of the main plate 30 'and the lamination plate 31, a stopper 34 is provided. The stopper 34 is for restricting the movement of the lapping plate 31 by hanging the moving wheel 40. Therefore, the stopper 34 contacts the moving wheel 40 at a position where the lamination plate 31 protrudes most, and prevents the lamination plate 31 from further moving. The stopper 34 may be provided at both ends of the main plate 30 'and the lamination plate 31. In this case, both of the movement strokes of the lamination plate 31 can be restricted.

Although not shown, the window frame 10 may be provided with fixing means. The fixing means is for fixing the most protruding lamination plate 31 among the plurality of lamination plates 31 and is provided at the right end portion 13 of the window frame 10 with reference to Fig. The fixing means may be formed in the form of a fixing protrusion and a fixing groove, or may be formed of a magnetic force of a magnet.

The lamination plate 31 can be moved by the adjusting means 70. The adjusting means 70 is connected to any one of the plurality of lamination plates 31, and is located on the opposite side across the window 10 '. And is connected to the laminating plate 31 by magnetic force to the adjusting means 70. Accordingly, the lamination plate 31 can be moved in a direction in which the lamination plate 31 is unfolded or laminated as the adjustment means 70 moves. 4, reference numeral 50 denotes a magnetic force module 50 provided in the lamination plate 31 located at the lowest one of the lamination plates 31. In the adjustment means 70 shown in FIG. 3, A separate magnet for applying a magnetic field is incorporated. Of course, either the magnetic force module 50 of the lamination plate 31 or the magnet embedded in the adjustment means 70 may be made of a magnet and a metal generating attraction.

The adjusting means 70 also functions to fix the lamination plate 31 in a protruded state. A force due to a magnetic force acts between the adjusting means 70 and the magnetic force module 50 of the laminating plate 31 with the window 10 'therebetween, so that the laminating plate 31 is moved downward It is possible to maintain the protruded state without being sagged. Of course, the adjusting means 70 may be provided with a separate fixing means, for example, a suction plate (not shown) for fixing to the window 10 ', so that the adjusting means 70 and the laminating plate 31 are more stably 10 '.

On the other hand, Fig. 6 shows another embodiment of the present invention. As shown in the figure, the plurality of stacked plates 131 are each provided with a storage space 135, and the stacked plates 31 stacked in the storage space 135 are accommodated. That is, the upper surface of the other lamination plate 31 is not closely adhered to the bottom surface of one lamination plate 31, but the remaining lamination plate 31 is provided in the storage space 135 of one lamination plate 31, Are all housed. In Fig. 6, the lamination plate 31 is completely stored in the storage space 135, but either one of the storage spaces 135 may be open.

Hereinafter, a process of unfolding or folding a light shelf of the present invention will be described with reference to the drawings. The following description will be made with reference to the embodiment shown in Figs. 1 to 4 for reference.

First, if the user unfolds the light shelf 30 and intends to introduce more natural light into the room, the light shelf 30 must be fully opened. To this end, the adjustment means 70 is first gripped and the adjustment means 70 is moved along the outer surface of the window 10 '. In this process, the lowermost lamination plate 31a moves together. This is because the laminating plate 31 moves along the adjusting means 70 because gravitation acts between the magnet module of the laminating plate 31a and the magnet of the adjusting means 70. [

Thus, since the user can adjust the length of the light shelf 30 in the room by using the magnetic force of the adjustment means 70, the user can safely and easily adjust the length of the light shelf 30 even in the high-rise.

Meanwhile, in this process, the moving wheel 40 provided on the lamination plate 31 rotates. The moving wheel 40 rotates in the rotating space 35 so that the relative movement between the upper and lower lamination plates 31 is performed more smoothly. More precisely, there are a pair of wheels which are actually rotated at both ends of the rotary shaft, and the pair of wheels are provided on different lamination plates 31, that is, on the upper lamination plate 31b and the lower lamination plate 31a And the two lamination plates 31 are rotated in the process of relative movement.

When the lowermost lamination plate 31a is completely protruded, the movement wheel 40 is caught by the stopper 34 of the relatively uppermost lamination plate 31b, so that the relatively upper lamination plate 31b Move together. Namely, the lamination plate 31 located at the lowest position and the lamination plate 31 positioned at the relatively upper position move in the direction in which they project together (in the direction of arrow 1 in Fig. 3). For reference, the stopper 34 may be caught by the stopper portion with a separate stopper portion, not the moving wheel 40. [

When the above process is repeatedly performed, all the lamination plates 31 protrude in a direction away from the main plate 30 ', and the lamination plate 31 at the lowermost end is fixed to the right end portion of the window frame 10 . As described above, the window frame 10 has fixing means, and the lamination plate 31 may be fixed thereto.

In this case, the lamination plate 31 is completely unfolded, and the amount of natural light that can be reflected by the light shelf 30 is maximized. In other words, the user can adjust the overall length while expanding or stacking the light shelf 30, and the user can arbitrarily adjust the amount of natural light flowing into the room according to the external weather change or the position of the sun through the length adjustment . In particular, since the light shelf 30 can not function in the nighttime or in a low weather condition, the user can maximize the viewing rights by stacking the light shelf 30 again. Or even in an environment where a strong wind is blown to the outside, the light shelf 30 is stacked again, so that the light shelf 30 can be prevented from being damaged by the wind.
