Description

Lighting handrail

Technical Field

The present disclosure relates to an illuminated armrest assembled with illumination on an armrest block.

Background

Conventionally, among handrails installed in stairs, walkways, and the like, there is known an illuminated handrail in which illumination is incorporated into a handrail cover. As such an illumination handrail, there is known an illumination handrail provided with: a handrail main body, i.e., a handrail cover, having a recess portion opened downward and penetrating in a longitudinal direction; a plurality of LED light sources disposed in the recess; and a lighting cover (see utility model registration No. 3202849) which is a translucent member disposed in the opening of the recess.

Disclosure of Invention

Problems to be solved by the invention

When the illumination handrail described in japanese patent application laid-open No. 3202849 is installed on a staircase, the directivity of the LED light source is strong, and therefore, when a pedestrian looks upstairs from downstairs, the light from the LED light source may enter the eyes and be dazzled.

However, if the luminosity of the LED light source illuminating the handrail is reduced in order to reduce the glare of the LED light source, sufficient luminance cannot be ensured as illumination.

Accordingly, an object of the present disclosure is to provide an illuminated handrail that can prevent glare from an LED light source and can illuminate with sufficient brightness when a pedestrian looks up from a low position when installed in a place having a difference in height, such as a staircase, an inclined road, or a stairwell.

Means for solving the problems

In order to achieve the above object, an illuminated armrest of a first aspect includes: a handrail cover wood, which is provided with a concave part which is opened downwards in a penetrating way along the length direction; an LED module in which a plurality of LED light sources are arranged in parallel in the recess of the handrail cover; and a lighting cover having a plate shape and disposed at an opening of the recess, wherein the lighting cover includes a louver portion in which a light transmitting layer and a light shielding layer are alternately and repeatedly disposed in a longitudinal direction or a width direction of the opening.

According to the illuminated handrail of the first aspect, since the louver sections in which the light-transmitting layers and the light-shielding layers are alternately laminated restrict the louver sections in the light emission direction, when the opening section of the handrail cover is viewed from the outside of the visual field, the light from the LED light source does not directly enter the eyes, and unpleasant glare felt by pedestrians can be prevented.

In the illuminated handrail of the second aspect, in the illuminated handrail of the first aspect, the adjacent LED light sources of the LED module are arranged such that emission optical axes of the LED light sources are inclined with respect to a virtual vertical plane passing through the LED light sources.

According to the illumination handrail of the second aspect, the emission optical axis of the LED light source is directed to the tread surface of the staircase or the floor surface of the corridor, thereby enabling illumination with sufficient brightness.

In the illuminated armrest according to the third aspect, in the illuminated armrest according to the first or second aspect, the light-transmitting layer and the light-shielding layer of the louver portion are alternately arranged in the longitudinal direction of the opening portion, and the light-shielding layer is arranged substantially orthogonal to the longitudinal direction of the opening portion.

According to the illuminated armrest of the third aspect, since the light emitted from the illumination cover in the longitudinal direction of the armrest cover is blocked by the light blocking layer disposed orthogonal to the longitudinal direction of the opening, it is possible to prevent the light from the LED light source from directly entering the eyes when the pedestrian looks up at the illuminated armrest from a low position. As a specific example, the illuminated handrail of the third aspect is more effective when installed in a place having a level difference such as a staircase or an inclined road.

A lighting handrail of a fourth aspect is the lighting handrail of the first or second aspect, wherein the light-transmitting layer and the light-shielding layer of the louver portion are alternately arranged in a width direction of the opening portion, and the light-shielding layer is arranged substantially parallel to a longitudinal direction of the opening portion.

According to the illuminated armrest of the fourth aspect, since the light emitted from the illumination cover in the width direction of the armrest cover is blocked by the light blocking layer disposed parallel to the longitudinal direction of the opening, it is possible to prevent the light from the LED light source from directly entering the eyes when the pedestrian looks up at the illuminated armrest from a low position. As a specific example, the illumination handrail of the fourth aspect is more effective when installed on a translucent wall surface, for example, a glass wall, in a place having a level difference, such as a staircase, an inclined road, or a stairwell.

In the illuminated armrest according to the fifth aspect, in the illuminated armrest according to the fourth aspect, the light shielding layer of the louver portion is disposed so as to be inclined with respect to a virtual vertical plane passing through the adjacent LED light sources.

According to the illuminated handrail of the fifth aspect, since the light from the LED light source can be directed to the tread surface of the staircase or the floor surface of the corridor, when the pedestrian looks up the illuminated handrail from the low position, the light from the LED light source can be more effectively prevented from directly entering the eyes.

In the illuminated armrest according to the sixth aspect, in the illuminated armrest according to the fifth aspect, the light shielding layer is substantially parallel to an emission optical axis of the LED light source.

According to the illuminated armrest of the sixth aspect, the illumination cover can limit the visual field range through which light from the LED light source is transmitted, and the light blocking layer can efficiently transmit light from the LED light source without blocking the light in the visual field range, so that the light can be more brightly irradiated.

A lighting handrail of a seventh aspect is the lighting handrail of any one of the first to sixth aspects, wherein a light diffusion plate is provided between the LED light source and the lighting cover.

According to the illuminated armrest of the seventh aspect, the light from the LED light sources is diffused by the light diffusion plate, and as a result, the light is diffused in a planar spread manner, so that it is possible to reduce the appearance of the light from the plurality of LED light sources as a star point in the illumination cover.

Effects of the invention

According to the present disclosure, when installed in a place having a difference in height, such as a staircase, an inclined road, or a stairwell, it is possible to prevent glare from the LED light source and to illuminate with sufficient brightness when a pedestrian looks up from a low position.

Detailed Description

Hereinafter, a mode of illuminating the handrail for carrying out the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the illuminated handrail 10 of the first example is provided on a wall W1 of a staircase and an upstairs corridor, and the illuminated handrail 100 of the second example is provided on a translucent glass fence G and a wall W2 of an upstairs corridor.

First, a first example of an embodiment of the present invention will be described with reference to fig. 2 to 6B.

As shown in fig. 2, the illuminated handrail 10 of the first example is supported by brackets 20 attached to the wall surface W1 at predetermined intervals, and is fixed to the wall surface W1 of the staircase or the upstairs corridor. As shown in fig. 3, the bracket 20 is formed by connecting 2 rods in an L shape, and is fixed to the wall W1 by screws or the like. A support member 21 is coupled to an upper end of the bracket 20, and the armrest cover 30 is fixed to the support member 21 by a screw or the like.

As shown in fig. 4, the illuminated armrest 10 includes an armrest cover 30 having a recess 31 that opens downward and that penetrates in the longitudinal direction, and an illumination unit 50 having an LED module 40.

The armrest cover 30 is formed in a substantially cylindrical shape having a recess 31 that opens downward by bending a metal plate such as stainless steel.

As shown in fig. 4 and 5, the illumination unit 50 includes an LED module 40, a case 60 that houses the LED module 40 and the cable 51, and an illumination cover 80 that closes the light projection opening 69 of the case 60.

As shown in fig. 5, the LED module 40 is formed by housing a strip-shaped printed circuit board 42, on which a plurality of LED light sources 41 are mounted in parallel at appropriate intervals, in a housing tube 43 made of a transparent soft synthetic resin.

As shown in fig. 4 and 5, 2 lead wires 52 on the anode side and the cathode side are connected to a circuit printed on the printed board 42 and LED out from the printed board 42 on one end side in the longitudinal direction of the printed board 42, and these lead wires 52 are connected to a power supply cable 51, whereby power can be supplied to the LED light source 41.

The arrangement interval of the LED light sources 41 is appropriately determined in consideration of the amount of light and the like.

The case 60 is formed by extrusion molding of metal such as aluminum. As shown in fig. 5, the housing 60 is configured by an LED module holding portion 61 that holds the LED module 40, a cable holding portion 62 that holds the cable 51, a pair of guide walls 63 provided with the lighting cover 80 and the light diffusion plate 90, and a pair of locking pieces 65 having locking claws 64.

A long rail member 66 is fixed to the top wall of the recess 31 of the armrest cover 30 with screws. The rail member 66 is provided with a pair of elastic locking pieces 67 at both ends, and the elastic locking pieces 67 are elastically fitted to the locking claws 64 of the housing 60 to hold the housing 60 on the rail member 66.

Flanges 68 are formed at the lower ends of the pair of guide walls 65, respectively, and a light projection opening 69 is formed between the pair of flanges 68. The light projection opening 69 is closed by a lighting cover 80 held by the pair of flanges 68. The opening 32 of the recess 31 is closed by the lighting cover 80 and the pair of flanges 68.

As shown in fig. 5, the adjacent LED light sources 41 are arranged such that the emission optical axis P of the LED light source 41, i.e., the optical axis having the largest amount of emitted light, is inclined with respect to a virtual vertical plane S passing through them. In the first example, the emission optical axis P of the LED light source 41 is inclined toward the wall surface W1 with respect to the virtual vertical plane S so as to face the tread surface of the staircase or the floor surface of the corridor.

As shown in fig. 6A and fig. 6B, which is a cross-sectional view taken along line B-B of fig. 6A, the lighting cover 80 is formed in a band plate shape. The illumination cover 80 is provided with a louver portion 81 that transmits incident light from the LED light source 41 while limiting the direction in which the light is emitted. As shown in fig. 5, the lighting cover 80 is attached to the lighting cover attachment groove 70 formed in the pair of guide walls 65 of the housing 60.

As shown in fig. 6B, the louver section 81 includes a light-transmitting layer 82 that transmits light of the LED light source 41 and a light-blocking layer 83 that blocks light of the LED light source 41. In the first example, the light-transmitting layers 82 and the light-shielding layers 83 are alternately arranged in the longitudinal direction of the opening 32 of the cut-out body 30, and the light-shielding layers 83 are arranged substantially orthogonal to the longitudinal direction of the opening 32. Light-transmitting layer 82 is formed from a transparent silicone rubber composition. The light-shielding layer 83 is formed by coloring the silicone rubber composition with colors such as black, blue, green, and red.

The thickness of the louver 81, that is, the thickness of the louver 81 in fig. 6B with respect to the left-right direction is preferably about 0.1 to 2.5 mm. The thickness of the light-transmitting layer 82, that is, the thickness of the light-transmitting layer 82 in fig. 6B with respect to the vertical direction is preferably about 0.05mm to 0.3mm, and the thickness of the light-shielding layer 83, that is, the thickness of the light-shielding layer 83 in fig. 6B with respect to the vertical direction is preferably about 0.005mm to 0.05 mm.

A heat-resistant highly transparent plastic film 84 such as polycarbonate is bonded to the front and back sides of the louver part 81, that is, to the left and right sides of the louver part 81 in fig. 6B. In the first example, the light-transmitting layer 82 and the light-shielding layer 83 are disposed so as to be perpendicular to the plastic film 84. The thickness of the plastic film 84 is preferably about 0.01mm to 0.5 mm.

As shown in fig. 5, a light diffusion plate 90 that diffuses and transmits light from the LED light sources 41 is provided between the LED module 40 and the lighting cover 80. The light diffuser plate 90 is attached to the light diffuser plate attachment groove 71 formed in the pair of guide walls 65.

Next, a method of attaching the illuminated handrail 10 of the first example to the wall surface W1 will be described.

First, at the construction site, the illumination unit 40, the rail member 66, the illumination cover 80, and the light diffusion plate 90 are cut off in accordance with the interval between the brackets 20, and the cable 51 is cut off to a slightly longer extent than the entire length of the armrest cover 30.

Then, the LED module 40 is fixed to the LED module holding portion 61 of the housing 60, the illumination cover 80 is inserted into the illumination cover mounting groove 70 of the guide wall 63, and the light diffusion plate 90 is inserted into the light diffusion plate mounting groove 71. Then, the cable 51 is stored in the cable holding portion 62.

Next, the rail member 66 is fixed to the ceiling wall of the recess 31 of the armrest cover 30 with screws, the housing 60 in which the LED module 40 and the like are housed is inserted into the recess 31, the elastic locking piece 67 of the rail member 66 is elastically fitted to the locking claw 64 of the housing 60, and the housing 60 is held by the rail member 66. At this time, the housing 60 is attached so that the emission optical axis P of the LED light source 41 becomes a tread surface of a staircase or a floor surface of a corridor.

Then, the coupling auxiliary member 91 is inserted into the recess 31 between the housings 60, and the armrest cover 30 is fixed to the bracket 20 via the support member 21 with a screw or the like.

Finally, if both ends of the cable 51 are led out to the inside of the wall surface W1 through appropriate holes and connected to a commercial power supply or a battery via a power supply control unit, the lighting of the handrail 10 is completed.

As shown in fig. 6A and 6B, according to the lighting handrail 10 of the first example, the light-transmitting layers 82 and the light-shielding layers 83 of the louver portion 81 of the lighting cover 80 are alternately arranged in the longitudinal direction of the opening portion 32, and the light-shielding layers 83 are arranged substantially orthogonal to the longitudinal direction of the opening portion 32, so that light emitted from the lighting cover 80 in the longitudinal direction of the handrail cover 30 is shielded by the light-shielding layers 83. Thus, when the illuminated handrail 10 is installed on a staircase, when a pedestrian looks upstairs from the downstairs side, the light from the LED light source 41 on the upstairs side can be prevented from directly entering the eyes of the pedestrian, and unpleasant glare can be prevented from being felt by the pedestrian.

As shown in fig. 5, according to the first example, when the illuminated handrail 10 is attached to the wall surface W1 by the bracket 20, the emission optical axis P of the LED light source 41 is inclined toward the wall surface W1 side with respect to the virtual vertical plane S so as to face the tread surface of the staircase and the floor surface of the corridor, and therefore, the tread surface of the staircase and the floor surface of the corridor can be illuminated with sufficient brightness.

Further, according to the first example, since the light diffusion plate 90 is provided between the LED module 40 and the lighting cover 80, the light from the LED light sources 41 is diffused by the light diffusion plate 90, and thus it is possible to reduce the case where the light of the plurality of LED light sources 41 looks like a star point in the lighting cover 80.

Next, a second example of the embodiment of the present invention will be described with reference to fig. 7 to 9.

The illuminated armrest 100 of the second example is different from the illuminated armrest 10 of the first example only in the lighting cover 80, and the other configurations are the same. Hereinafter, with respect to the second example, the description of the first example will be referred to for details regarding the same configuration as the first example.

As shown in fig. 8 and 9, the lighting cover 110 of the second example has the light-transmitting layers 112 and the light-shielding layers 113 of the louver section 111 of the second example alternately arranged in the width direction of the opening 32 of the armrest cover 30, and the light-shielding layers 113 are arranged substantially parallel to the longitudinal direction of the opening 32.

The thickness of the louver part 111, that is, the thickness of the louver part 111 in fig. 9 with respect to the vertical direction is preferably about 0.1 to 2.5 mm. The thickness of the light-transmitting layer 112, that is, the thickness of the light-transmitting layer 112 in fig. 9 with respect to the left-right direction is preferably about 0.05mm to 0.3mm, and the thickness of the light-shielding layer 113, that is, the thickness of the light-shielding layer 113 in fig. 9 with respect to the left-right direction is preferably about 0.005mm to 0.05 mm.

A heat-resistant highly transparent plastic film 114 such as polycarbonate is bonded to the front and back sides of the louver part 111, i.e., the upper and lower sides of the louver part 111 in fig. 9.

In the second example, as shown in fig. 8 and 9, the light shielding layer 113 of the louver section 111 is disposed obliquely to a virtual vertical plane S passing through the adjacent LED light sources 41, and the light shielding layer 113 is substantially parallel to the emission optical axis P of the LED light source 41. That is, in the second example, as shown in fig. 9, the light-transmitting layer 112 and the light-shielding layer 113 are substantially parallel to the emission optical axis P of the LED light source 41.

As shown in fig. 8 and 9, according to the lighting handrail 100 of the second example, the light-transmitting layers 112 and the light-shielding layers 113 of the louver portion 111 of the lighting cover 100 are alternately arranged in the width direction of the opening portion 32, and the light-shielding layers 113 are arranged substantially parallel to the longitudinal direction of the opening portion 32, so that the light emitted from the lighting cover 110 in the width direction of the handrail member 30 is shielded by the light-shielding layers 113. Further, since the light shielding layer 113 is inclined toward the glass fence G with reference to the virtual vertical plane S passing through the adjacent LED light sources 41, the light emitted from the light cover 110 in the direction of the glass fence G is shielded. Thus, as shown in fig. 7, when the lighting handrail 100 is installed in the glass fence G of the upstairs corridor, when a pedestrian downstairs looks up the upstairs, the light from the LED light source 41 can be prevented from directly entering the eyes of the pedestrian over the glass fence G.

Further, according to the second example, as shown in fig. 1, when the lighting handrail 100 is attached to the glass fence G or the wall surface W2 by the bracket 20, the LED light sources 41 are arranged such that the emission optical axis P is inclined toward the glass fence G with respect to the virtual vertical plane S, and the louver portion 111 is arranged such that the light shielding layer 113 is substantially parallel to the emission optical axis P. This allows the light from the LED light source 41 to be efficiently emitted to the floor of the upstairs corridor, thereby achieving brighter illumination.

The present invention is not limited to the above-described embodiments, and can be modified as appropriate within a scope not departing from the gist of the present invention.

In the present embodiment, the

illuminated handrails

10 and 100 are attached to a wall surface or the like by the brackets 20, but a plurality of handrail supports may be erected on a staircase, an inclined road, or the like, and the

illuminated handrails

10 and 100 may be erected on the handrail supports. In this case, the cable 51 may be drawn out to a space below the stairway via the handrail support and then connected to a commercial power supply or the like. In the present embodiment, the housing 60 and the rail member 66 are separate bodies, but the housing and the rail member may be integrally formed.
