  However, in the bed device to which the lighting device of Patent Document 1 is applied, it is difficult to illuminate the floor surface beside the bed because the light emitting diode is provided on the headboard. When a light emitting diode is installed under the side frame to illuminate the floor surface next to the bed, the distance from the light emitting diode installation position to the floor surface is shortened. Difficult to irradiate. If a light emitting diode is installed on the underside of the headboard to illuminate the floor next to the bed, the distance to the floor will be reduced and the side frame will block the light. Difficult to illuminate the floor.

  In the bed of Patent Document 2, an illumination facility space using a light emitting diode as an illuminating lamp is provided between the mat support base and the side plate, and the side plate is formed of a transparent or translucent material. When used as a light, the light-emitting diode, which is a illuminating lamp, directly enters the user's field of view, and may cause discomfort to the user when shifting from a low awakening stage to a high awakening stage. is there. The light emitting diode is wired to rectify an AC voltage into a DC voltage to a predetermined rated voltage and supply a predetermined current via a resistor. If this wiring is made at or near the area where the user next to the bed frequently gets on or off (the area where the load is frequently applied or near the area), the user must step on the wiring when getting on and off the bed. There is a risk of being. In addition, depending on the position of the wiring, there is a risk of damage to the wiring due to the user getting caught in the wiring or the wiring being sandwiched between the side plate of the bed and the wall surface or floor surface of the room. . In addition, when the lighting equipment space is provided in two places between the mat support base and the left and right side plates, wiring is made to these two places, so that wiring may be complicated. When wiring is complicated, when packing a bed, processing for protecting the wiring also takes time.

  In the bed of Patent Document 3, at least a part of the bed main body is formed of a magnetic material, and a footlight having a magnet is detachably provided by being magnetically coupled to a portion formed of the magnetic material. When used as an auxiliary light at night, the footlight directly enters the user's field of view, which may give the user discomfort when transitioning from a low arousal stage to a high awakening stage. . The footlight can be powered by a dry cell or an AC adapter. When the footlight is powered by the AC adapter, the wiring is located near or near the part where the user next to the bed gets on and off (frequently load If it is made at or near the part), there is a risk that the user may get caught in the wiring when getting on and off the bed. Further, depending on the position of the wiring, there is a risk of damage to the wiring due to the user's foot being placed on the wiring or the wiring being sandwiched between the bed body and the wall surface or floor surface of the room.

  In the bed apparatus of patent document 4, since the footlight is mounted on the bed frame mounted on the floor surface and is connected to the AC 100V power source, the user next to the bed frequently gets on and off the bed. If it is applied to a portion or the vicinity thereof (a portion where the load is frequently applied or the vicinity thereof), there is a possibility that the user may get caught in the wiring when getting on and off the bed. Further, depending on the position of the wiring, there is a risk of damage to the wiring due to the user's stepping on the wiring or the wiring being sandwiched between the bed frame and the wall or floor of the room. In addition, since the footlights are provided on the lower surfaces of both side frames and the lower surface of the footboard, and wiring is made to them, wiring may be complicated. When wiring is complicated, when packing a bed, processing for protecting the wiring also takes time.

  In the bed apparatus of patent document 5, since the footlight is provided in the attachment recessed part formed in the side part of the bed main body and opening downward, the wiring to the footlight is connected to the user next to the bed. If it is placed in or near a part where it gets on and off frequently (a part where the load is frequently applied or its vicinity), there is a risk that the user may get caught in the wiring when getting on or off the bed. In addition, depending on the position of the wiring, there is a risk of damage to the wiring due to the user getting caught in the wiring or the wiring being sandwiched between the side of the bed body and the wall or floor of the room. There is.

The present invention has been made in view of the above problems, and can prevent the light source from directly entering the user's field of view. It aims at providing the bed apparatus which can illuminate a floor surface.

  In order to solve the above problems, a bed apparatus according to the present invention includes a headboard, a side frame extending from an end of the headboard, a light source provided on the headboard and irradiating the side frame, and the side frame. And a reflecting member that reflects the light irradiated by the light source and illuminates the floor surface beside the side frame.

  In this case, the reflection member may be a reflection surface included in the side frame.

  The reflecting surface may be inclined with respect to the floor surface.

  Furthermore, the reflecting surface may be concave or convex.

  Furthermore, the material of the side frame is preferably an aluminum alloy, and the surface of the aluminum alloy is preferably the reflective surface.

  Moreover, the said reflection member is good to have a reflecting plate in the said side frame.

  Furthermore, the said reflecting plate is good to incline with respect to a floor surface.

  Furthermore, the reflection member may be provided with a transmission member having at least one light diffusion surface.

  Furthermore, the headboard may include an irradiation direction adjusting mechanism that adjusts the irradiation direction of the light source.

  Furthermore, the light source may be provided inside the headboard, and the headboard may include a light passage hole through which light emitted from the light source passes.

  According to the above-described means, the light source is provided on the headboard, irradiates the side frame, and the reflection member reflects the light irradiated by the light source to illuminate the floor surface beside the side frame (next to the bed apparatus). . This is so-called indirect lighting. Therefore, since it is possible to prevent the light source from directly entering the user's field of view, it is possible to prevent the user from feeling uncomfortable when shifting from the low awakening stage to the high awakening stage. In addition, the reflecting member can illuminate the floor surface of the side frame (side of the bed apparatus) over a wide range. Moreover, since a part of light is diffused by the reflecting member, it is visually recognized by the user as if the outside of the reflecting member, that is, the side frame is shining. That is, the user can know the position of the side frame even when the surroundings are dark, so that the user is less likely to accidentally hit the side frame. In addition, since the light source is provided on the headboard, the light source is provided with simpler wiring than before, and the area where the user next to the bed apparatus frequently gets on and off the area (the area where the load is frequently applied or its vicinity) Wiring to is unnecessary. And the process which protects wiring when packing a bed apparatus can be simplified. In addition, the bed apparatus can be easily prepared by inserting the power cord on the headboard side into the outlet.

  Furthermore, if the reflecting surface has a concave shape, the light can be condensed at an arbitrary place on the floor surface beside the side frame (next to the bed apparatus). Further, if the reflecting surface is formed in a convex shape, light can be diffused more on the floor surface beside the side frame (side of the bed apparatus) than the inclined reflecting surface.

  Furthermore, if the material of the side frame is an aluminum alloy and the surface of the aluminum alloy is a reflective surface, the integral molding can be easily performed by extrusion molding. Moreover, the reflectance of a reflective surface can be raised by surface-treating to a reflective surface.

  Further, if the reflecting member is a reflecting plate provided on the side frame, the reflecting plate can be provided on an existing bed, for example, made of a low reflectance material for the side frame. As a result, it is possible to prevent the light source from directly entering the user's field of view, the light source is provided with simpler wiring than before, and illuminates the floor surface beside the side frame (next to the bed apparatus) over a wide area. Can be easily remodeled into a bed device.

  Furthermore, if the reflecting plate is inclined with respect to the floor surface, the floor surface on the side of the side frame (side of the bed apparatus) can be illuminated in a wider range than before.

  Furthermore, if the reflecting member is provided with a transmissive member having at least one light diffusing surface, the light irradiated by the light source can be diffused by the diffusing surface and reflected by the reflecting member. It can illuminate the floor side of the side frame (next to the bed device) over a wide area. Further, since the light is diffused by the diffusing surface, the floor surface beside the side frame (the side of the bed apparatus) can be illuminated with the light that the user feels soft.

  Furthermore, if the headboard is provided with an irradiation direction adjustment mechanism that adjusts the irradiation direction of the light source, the position of the side frame that illuminates the side of the side frame (next to the bed apparatus) is changed according to the user's preference. It becomes possible.

  Furthermore, if the light source is provided inside the head board and the head board is provided with a light passage hole through which the light emitted from the light source passes, it is possible to more reliably prevent the light source from directly entering the user's field of view. Further, when the light source is provided inside the headboard via the irradiation direction adjusting mechanism, the ratio of the amount of light passing through the light passage hole to the amount of light irradiated by the light source can be changed. Also, the user prefers the position and amount of light that the light source irradiates and passes through the light passage hole is reflected by the reflecting member and illuminates the floor beside the side frame (next to the bed apparatus). It can be changed accordingly.
