Description

The present invention relates to a blower reflector or an illumination reflector that adjusts the wind direction and light distribution.

As the blower cover capable of diffusing the wind direction, for example, there is one described in Patent Document 1, and there is also a cover like Patent Document 2 in which an air film by an air curtain surrounds a person. If the wind direction diffuses in a conical shape, it can function as a circulator that blocks and diffuses the wind of the air conditioner with a surface depending on the angle of the cone. In addition, if the wind direction is spread within the range of the personal space avoiding the vicinity of the human face, it is also effective as a countermeasure against droplet infection.

As the lighting cover whose light distribution can be adjusted, there is one described in Patent Document 3, and there is also a foldable one as in Patent Document 4. Further, among the lighting covers whose light distribution can be adjusted, those assembled from one material include those described in Patent Documents 5 to 7. If the light distribution is diffused in a conical shape, depending on the angle of the cone, it exerts an effect as a spotlight at a narrow angle and an indirect illumination at a wide angle.

The reflector main body (2) is a thin plate-shaped member, and can be molded into a thin plate-shaped (planar) material such as metal, acrylic, plastic, or Waron paper, and the reflector main body. It is formed of a material that elastically deforms within the movable range of (2). The inner surface (21) of the reflector main body (2) is made of a glossy metal, a white material, or the like in which light is easily diffused when lighting is used.

FIG. 5 is a developed view of the reflector main body (2). The reflector main body (2) has an annular fan shape in a plan view. Specifically, the developed shape of the reflector main body (2) is a fan shape having an arbitrary central angle (or a circle with a notch in the radius) provided with a hole (23) in the center. .. The diameter of the hole (23) is arbitrary, and the central angle of the hole (23) is the same as the central angle of the fan shape.

By forming the reflector body (2) in such a shape, the reflector body (2) is three-dimensionally wound like a vortex from a state in which it is unfolded in a plane, and both ends of an annular fan shape are overlapped with each other. As a result, the reflector body (2) has a cylindrical shape having a three-dimensional truncated cone side surface. The angle (taper angle) of the truncated cone in the side surface direction of the reflector body (2) can be changed depending on the size of the area of the overlapping portions (26) at both ends of the annular fan shape of the reflector body (2).
When changing the angle, the outer peripheral edge (25) in the front direction (in this embodiment, the direction in which wind or light is emitted) while maintaining the shape in which the reflector main body (2) is integrated and has few gaps and seams. Scales while maintaining a circular shape.
As described above, the material of the reflector body (2) is an elastic body that can be elastically deformed within the movable range, but it is not close to a completely elastic body such as rubber and is semi-plastic. It may be a thing. By using such a semi-plastic material, the taper angle exceeds θ2 in FIG. 11, which will be described later, even once from the state where the reflector main body (2) has a cylindrical shape having the side surface of a three-dimensional truncated cone. If the reflector body (2) is wound so as to be smaller, the shape memory works, and both ends of the annular fan piece are overlapped by using the fasteners (3) and (30) and the auxiliary fastener (31) described later. Even if the state is not physically held, it can be kept close to it.

As shown in FIG. 6, at the end of the outer peripheral edge (25) of the annular fan shape of the reflector main body (2), two fasteners (3) for maintaining the overlapping state of both ends of the annular fan shape, (30) is provided, and an auxiliary fastener (31) is provided at the end of the inner peripheral edge (24).

At least two fasteners are required on the outer peripheral edge (25) of the annular fan shape, but the auxiliary fastener (31) on the inner peripheral edge (24) is optional.

When the overlapping portion is changed from the overlapping portion (26) shown in FIG. 6 to the overlapping portion (27) shown in FIG. 7, the center angle of the upper and lower bottom surfaces of the truncated cone is the same, but the rotation angle of the circle is the same. Since the lower bottom surface, which has a larger circle diameter, has a larger amount of movement than the upper bottom surface, which has a smaller diameter, the air blow and illumination are applied to the inner surface (21) of the reflector body (2) while smoothly changing the angle of the side surface of the truncated cone. The angle of reflection when hitting the cone can be made variable.

Further, the blower / illumination reflector (1) is provided with an auxiliary connecting portion (7) for connecting the reflector main body (2) and the blower / illumination storage portion (4). The connecting portion (7) includes a rod-shaped connecting shaft (51b). One end (54) of the connecting shaft (51b) is in contact with a part of the inner peripheral edge (24) of the annular fan shape of the reflector main body (2) without being fixed. By not fixing in this way, it is possible to cope with the movement of the reflector main body (2) due to the change of the overlapping portion (26) and (27). A through hole (52b) is provided at the other end of the connecting shaft (51b), and is rotatably connected to the blower / lighting storage unit (4).

Specifically, while the other end of the connecting shaft (51b) is arranged in the through hole (57b) of the ventilation / lighting storage unit (4), the rotating shaft (55a) is the ventilation / lighting storage unit. It penetrates through the through holes (56a) and (56b) of (4) and the through holes (52b) of the connecting shaft (51b). As a result, the connecting portion (7) is rotatably connected to the blower / lighting storage portion (4) about the rotation shaft (55a).
