Lighting armrest

Technical Field

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

Background

Conventionally, in an armrest provided in a stair, a passage way, or the like, an illumination armrest in which an illumination is assembled to an armrest cover is known. As such an illumination handrail, an illumination handrail is known which includes: a handrail cover wood which is a handrail main body having a recess opening downward in a longitudinal direction; a plurality of light emitting diodes (LED light sources) disposed in the concave portion; and an illumination cover which is a light-transmitting member disposed at an opening of the recess (see japanese patent application laid-open No. 3202849).

Disclosure of Invention

Problems to be solved by the utility model

When the illumination handrail described in japanese patent application laid-open No. 3202849 is provided on a stair, the directivity of the LED light source is strong, so that when a pedestrian looks up on the stair from the lower part of the stair, the light of the LED light source may enter the eyes and become blinded.

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

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

Means for solving the problems

In order to achieve the above object, an illumination handrail according to a first aspect includes: a handrail cover wood which is provided with a concave part which is opened downwards along the length direction in a penetrating way; an LED module in which a plurality of LED light sources are arranged in parallel in a recess of the armrest cover wood; and a band-shaped illumination cover disposed in an opening of the recess, wherein the illumination 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 illumination handrail of the first aspect, since the louver portions in which the light-transmitting layer and the light-shielding layer are alternately laminated limit the light emission direction louver portions, when the opening portion of the handrail cover is observed from the outside of the visual field, the light of the LED light source does not directly enter the eyes, and unpleasant glare felt by pedestrians can be prevented, and in addition, illumination can be performed with sufficient brightness in the visual field.

In the illumination handrail according to a second aspect, in the illumination handrail according to the first aspect, the LED light sources adjacent to each other in the LED module are arranged such that the emission optical axes of the LED light sources are inclined with respect to an imaginary vertical plane passing through the LED light sources.

According to the illumination handrail of the second aspect, the light emission axis of the LED light source is directed to the tread of the stair or the floor of the corridor, so that the illumination handrail can illuminate with sufficient brightness.

In the illumination handrail according to a third aspect, in the illumination handrail according to the first or second aspect, the light-transmitting layers and the light-shielding layers of the louver portion are alternately arranged in the longitudinal direction of the opening portion, and the light-shielding layers are arranged substantially orthogonal to the longitudinal direction of the opening portion.

According to the illumination armrest of the third aspect, the light emitted from the illumination cover in the longitudinal direction of the armrest cover is blocked by the light blocking layer disposed perpendicularly to the longitudinal direction of the opening, so that the light from the LED light source can be prevented from directly entering the eyes when the pedestrian looks up at the illumination armrest from a low position. As a specific example, the illumination handrail of the third aspect is more effective when installed in a place having a height difference such as a stair, an inclined road, or the like.

In the illumination handrail according to a fourth aspect, in the illumination handrail according to the first or second aspect, the light-transmitting layers and the light-shielding layers of the louver portion are alternately arranged in the width direction of the opening portion, and the light-shielding layers are arranged substantially parallel to the longitudinal direction of the opening portion.

According to the illumination armrest of the fourth aspect, the light emitted from the illumination cover in the width direction of the armrest cover wood is blocked by the light blocking layer disposed parallel to the longitudinal direction of the opening, so that the light from the LED light source can be prevented from directly entering the eyes when the pedestrian looks up at the illumination armrest from a low position. As a specific example, the illumination handrail of the fourth aspect is more effective in a light-transmitting wall surface, for example, a glass wall, provided in a place having a height difference such as a stairway, an inclined road, a stairwell, or the like.

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

According to the illumination handrail of the fifth aspect, the light of the LED light source can be directed to the tread of the stair or the floor of the corridor, so that when the pedestrian looks up at the illumination handrail from a low position, the light of the LED light source can be more effectively prevented from directly entering the eyes.

In the illumination handrail according to a sixth aspect, in the illumination handrail 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 illumination handrail of the sixth aspect, the illumination cover can limit the field of view through which light from the LED light source passes, and the light shielding layer can efficiently pass through the LED light source without shielding the light from the LED light source in the field of view, so that the illumination handrail can illuminate brightly.

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

According to the illumination handrail of the seventh aspect, since 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 shape, it is possible to reduce the situation that the light from the plurality of LED light sources looks like a star point in the illumination cover.

Effects of the utility model

According to the present disclosure, when the LED light source is installed in a place having a height difference such as a stairway, an inclined road, or a stairwell, the LED light source can be prevented from being blinded when a pedestrian looks up from a low place, and can be illuminated with sufficient brightness.

Detailed Description

The manner in which the illumination handrail of the present utility model is implemented will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the illumination handrail 10 of the first example is provided on a wall surface W1 of a stairway or an upstairs corridor, and the illumination handrail 100 of the second example is provided on a glass fence G and a wall surface W2 having light transmittance of the upstairs corridor.

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

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

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

The armrest lid 30 is formed into a substantially cylindrical shape having a recess 31 opening 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 accommodating the LED module 40 and the cable 51, and an illumination cover 80 closing the light projecting opening 69 of the case 60.

As shown in fig. 5, a tape-shaped printed board 42 on which a plurality of LED light sources 41 are mounted in parallel at appropriate intervals is housed in a housing tube 43 made of transparent soft synthetic resin to form an LED module 40.

As shown in fig. 4 and 5, at one end side in the longitudinal direction of the printed circuit board 42, 2 leads 52 on the anode side and the cathode side are connected to a circuit printed on the printed circuit board 42 and LED out from the printed circuit board 42, and these leads 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 a 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 illumination cover 80 and the light diffusion plate 90, and a pair of locking pieces 65 having locking claws 64.

An elongated rail member 66 is screwed to the top wall of the recess 31 of the armrest lid 30. 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 into locking claws 64 of the housing 60 to hold the housing 60 to the rail member 66.

Flange portions 68 are formed at lower ends of the pair of guide walls 65, respectively, and a light projecting opening 69 is formed between the pair of flange portions 68. The light projecting opening 69 is closed by a lighting cover 80 held by the pair of flange portions 68. The opening 32 of the recess 31 is closed by the illumination cover 80 and the pair of flange portions 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, that is, the optical axis having the largest amount of emitted light, is inclined with respect to an imaginary 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 reference to the virtual vertical surface S so as to face the tread of the stairs or the floor of the corridor.

As shown in fig. 6A and fig. 6B, which is a sectional view taken along line B-B of fig. 6A, the illumination cover 80 is formed in a band plate shape. The illumination cover 80 is provided with a louver 81 that allows light from the LED light source 41 to pass therethrough while restricting the emission direction of the light. As shown in fig. 5, the illumination cap 80 is mounted in the illumination cap mounting groove 70 formed in the pair of guide walls 65 of the housing 60.

As shown in fig. 6B, the louver portion 81 includes a light-transmitting layer 82 that transmits light from the LED light source 41 and a light-shielding layer 83 that shields light from 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 wood cover body 30, and the light-shielding layers 83 are arranged substantially orthogonal to the longitudinal direction of the opening 32. The light-transmitting layer 82 is formed of a transparent silicone rubber composition. The light shielding layer 83 is formed by coloring a silicone rubber composition with black, blue, green, red, or the like.

The thickness of the louver portion 81, that is, the thickness of the louver portion 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 highly transparent plastic film 84 having heat resistance, for example, polycarbonate or the like is attached 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 arranged 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 source 41 is provided between the LED module 40 and the illumination cover 80. The light diffusion plate 90 is attached to the light diffusion plate attaching groove 71 formed in the pair of guide walls 65.

Next, a method of attaching the illumination 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 in conformity with the interval between the brackets 20, and the cable 51 is cut to a degree slightly longer 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 cap 80 is inserted into the illumination cap 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 accommodated in the cable holding portion 62.

Next, the rail member 66 is fixed to the top wall of the recess 31 of the armrest lid 30 by screws, the case 60 accommodating the LED module 40 and the like is inserted into the recess 31, and the elastic locking piece 67 of the rail member 66 is elastically fitted to the locking claw 64 of the case 60, thereby holding the case 60 to 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 the tread of the stairs or the floor of the corridor.

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

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

As shown in fig. 6A and 6B, according to the illumination handrail 10 of the first example described above, the light-transmitting layers 82 and the light-shielding layers 83 of the louver portion 81 of the illumination 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 illumination cover 80 in the longitudinal direction of the handrail cover wood 30 is blocked by the light-shielding layers 83. Thus, when the illumination handrail 10 is provided in a stair, the light from the LED light source 41 on the upper side of the stair can be prevented from directly entering the eyes of the pedestrian when the pedestrian looks up on the stair from the lower side of the stair, and unpleasant glare felt by the pedestrian can be prevented.

As shown in fig. 5, according to the first example, when the illumination 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 with respect to the virtual vertical plane S so as to face the tread surface of the stair or the floor surface of the corridor, and therefore the tread surface of the stair or 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 illumination cover 80, the light from the LED light sources 41 is diffused by the light diffusion plate 90, and thus the situation in which the light from the plurality of LED light sources 41 looks like a star point in the illumination cover 80 can be reduced.

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

The illumination handrail 100 of the second embodiment is different from the illumination handrail 10 of the first embodiment only in the illumination cover 80, and has the same configuration. Hereinafter, the second example is described in detail with reference to the first example, with respect to the same configuration as the first example.

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

The thickness of the louver portion 111, that is, the thickness of the louver portion 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 about 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 about 0.05 mm.

A highly transparent plastic film 114 having heat resistance, such as polycarbonate, is attached to the front and back sides of the louver part 111, that is, to 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 portion 111 is arranged so as to be inclined with respect to the 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 sources 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 illumination handrail 100 of the second example, the light-transmitting layers 112 and the light-shielding layers 113 of the louver portion 111 of the illumination hood 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 length direction of the opening portion 32, so that light emitted from the illumination hood 110 in the width direction of the handrail cover wood 30 is shielded by the light-shielding layers 113. Further, since the illumination cover 110 is inclined toward the glass fence G with the virtual vertical plane S passing through the adjacent LED light sources 41 as the reference light shielding layer 113, light emitted from the illumination cover 110 in the glass fence G direction is shielded. Thus, as shown in fig. 7, when the illumination handrail 100 is provided in the glass fence G of the upstairs corridor, the light from the LED light source 41 can be prevented from directly entering the eyes of the pedestrian beyond the glass fence G when the pedestrian under the corridor looks up on the upstairs.

In addition, according to the second example, as shown in fig. 1, when the illumination handrail 100 is mounted on the glass rail G or the wall surface W2 by the bracket 20, the LED light source 41 is arranged such that the emission optical axis P is inclined toward the glass rail G side with the virtual vertical surface S as a reference, 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 corridor above the floor, thereby making the floor brighter.

The present utility model is not limited to the above-described embodiments, and can be appropriately modified within the scope not departing from the gist of the present utility model.

In the present embodiment, the illumination handrails 10 and 100 are mounted on the wall surface or the like by the brackets 20, but a plurality of handrail supports may be erected on stairs, inclined roads or the like, and the illumination handrails 10 and 100 may be erected on these handrail supports. In this case, the cable 51 may be led out to a space below the stairs via the armrest strut, and then connected to a commercial power source or the like. In the present embodiment, the housing 60 and the rail member 66 are separate, but the housing and the rail member may be integrally formed.

The entire disclosure of japanese patent application No. 2019-113700, filed on 6 months and 19 days of 2019, is incorporated herein by reference.

All documents, patent applications and technical standards described in the present specification are incorporated in the present specification by reference, and the degree to which each document, patent application and technical standard is incorporated by reference is the same as in the case of specific and individual descriptions.
