Description

  The present invention relates to a handrail headboard and a lighting unit.

  As a handrail headboard provided with illumination, what was conventionally described in patent document 1 is known. In this conventional example, the handrail body (caps wood) is made of a stainless extruded tube formed in a cylindrical shape having a concave groove. Inside the concave groove, a tape-like substrate soldered with an LED serving as a light source is attached to a position near the open end via an illumination fixing base, and these LED, tape-like substrate, and the illumination fixing base cover the concave groove. Covered by a light cover attached to the handrail body. The illumination fixing base has a U-shaped cross section that opens toward the bottom wall of the groove, and the LED and the tape-shaped substrate are coated with a flexible resin so as to form a rectangular cross section as a whole.

  In addition, a plurality of the tape-shaped substrates are arranged at intervals in the longitudinal direction of the handrail body, and the fixing base for illumination and the flexible resin are formed in a width dimension that approximates a concave groove, so that power is supplied to the LEDs. For example, a power supply cable is laid along the longitudinal direction of the handrail body using a gap inside the lighting fixture, and each tape substrate is electrically connected to a commercial power source or the like via the power supply cable. It is thought that it is appropriate to connect to.

  However, the above-described conventional example has a drawback of poor workability.

  In other words, in order to ensure high flexibility in accordance with the situation at the construction site, it is desirable that the power supply cable be retrofitted after checking the assembly status of the light source to the handrail body and taking this into account. Such a construction becomes difficult if the structure is as in the conventional example.

  The present invention has been made to eliminate the above drawbacks, and an object of the present invention is to provide a handrail head with excellent workability. Another object of the present invention is to provide an illumination unit having excellent workability.

According to the invention, the object is
A cap lumber 2 provided with a notch 1 that opens downward in the longitudinal direction;
The light source unit 4 and the power supply cable 5 are held in a case 7 that is provided with an engagement wall 6 having a substantially U-shaped cross section that opens downward and engages in the cutout portion 1 and is fixed to the cap lumber 2. A lighting unit 3;
The power supply cable 5 is supported by a cable support piece 9 protruding from the lower end edge of one side wall of the engagement wall 6 of the case 7, and
The power supply cable 5 and the light source unit 4 are achieved by providing a handrail cap arranged in the width direction of the illumination unit 3 .

  According to the present invention, the handrail headwood has the lighting unit 3 in which the lighting components such as the light source and the power supply wiring are united, and the lighting unit 3 is opened to the lower side of the headwood 2. 1 is formed in a fixed manner. The unitization of lighting makes it possible to eliminate the hassle of assembling a large number of lighting components into the shade wood 2 one after another, and it is extremely easy to assemble and replace the illumination on the shade wood 2 in the field. become. In addition, the lighting unit 3 is arranged in the cutout portion 1 that opens below the headwood 2 so that the position of the handrail headwood can be notified by the illumination light without making the pedestrian feel too dazzling in the dark. In addition, it enables safe walking by illuminating the feet of pedestrians walking with the handrail headboard.

  The illumination unit 3 has a light source unit 4 in which components around the light source are unitized, thereby making it difficult to assemble the illumination unit 3 by sequentially assembling a number of components around the light source one after another. It can be omitted and the replacement work around the light source can be simplified. The light source unit 4 described above is arranged and held in the width direction in the lighting unit 3 with the power supply cable 5. For this reason, the power supply cable 5 is assembled later in the cutout portion 1 opened below the cap lumber 2. In this case, the light source unit 4 does not get in the way.

  Therefore, according to the present invention, since the light source unit 4 and the power supply cable 5 can be sequentially assembled to the shade wood 2 after confirming the installation status of the shade wood 2 at the construction site, It is possible to perform highly flexible construction according to the requirements. In particular, since the lighting unit 3 is arranged in a limited space in the cutout portion 1, it is possible to perform such highly flexible construction, for example, because the length of the power supply cable is found to be insufficient at the stage of construction. In addition to avoiding the problem that it is necessary to disassemble the handrail headboard and start the construction again, it is also possible to prevent the length from being too long so that it cannot fit in the limited wiring space.

  Further, when the light source unit 4 and the power supply cable 5 are arranged in the width direction as described above, the light source unit 4 can be arranged at a deeper position in the cutout portion 1 as compared with the conventional example in which these are arranged in the vertical direction. Therefore, it is possible to suppress mischief to the light source unit 4 in the installed state or feeling dazzling when looking up at the upper floor side while going up the stairs. Furthermore, according to such an arrangement, it is easy to attach the light source to a position that deviates in the width direction of the handrail headboard. By using such an arrangement of the light source, the illumination range can be narrowed down efficiently. Will also be easier.

  If the illumination unit 3 includes a case 7 that holds the light source unit 4 and the power supply cable 5 therein, the case 7 is assembled in the cutout portion 1 of the shade wood 2 before the light source unit 4 and the like are assembled. As a result, it is possible to make the assembling work of the light source unit 4 and the like into the cutout portion 1 easier. In this case, if the outer wall is formed in a substantially U-shaped cross section that opens downward as in the case of the cutout portion 1, the case 7 will not be a problem when the light source unit 4 and the like are retrofitted. Further, if the outer wall is sized to engage with the cutout portion 1, it is possible to easily prevent a gap that may cause a finger from being caught between the cutout portion 1 and the inner wall.

  The light source unit 4 and the power supply cable 5 can be held by the case 7 by, for example, adhering them to the inner wall of the case 7. For example, a support piece, a holding piece, or a locking piece can be attached to the case 7. If it is formed, supported, clamped, or locked, the work for retrofitting the light source unit 4 and the like is simplified.

  The light source unit 4 described above can be configured using an appropriate light source such as a fluorescent tube or an LED. For example, when a light emitting element such as an LED is used, the light source unit 4 is easier to miniaturize than a fluorescent tube and consumes power. It is not difficult to suppress the life and extend the life. However, if the point light source 8 such as an LED is used, a granular reflection may occur when the floor surface of the handrail headboard is mirror-finished, which may make it look bad. 11 can be eliminated by retrofitting the illumination unit 3 below the point light source 8.

  Further, when the light diffusing plate 11 is retrofitted as described above, if the locking portion 10 for holding the light diffusing plate 11 by elastic locking is provided in the case 7, it is possible to attach the light diffusing plate 11 with an adhesive. Such a risk that the amount of light is reduced due to the adhesive sticking out from the bonding site can be avoided.

The above handrail Kasagi

A light source unit 4 formed by mounting the light emitting elements 13 on the printed circuit board 12 at a predetermined pitch;
A power supply cable 5 electrically connected to the printed circuit board 12, and
An engagement wall 6 having a substantially U-shaped cross section that opens downward is engaged in the cutout portion 1 of the cap lumber 2, and the light source unit 4 and the power supply cable 5 are arranged and held in the width direction. And a case 7 fixed in the notch 1,
The case 7 is formed with a cable support piece 9 that extends from the lower end edge of one side wall of the engagement wall 6 in the direction of narrowing the opening width and supports the power supply cable 5, and the tip of the cable support piece 9 It can be formed using the illumination unit 3 in which the light diffusion plate 11 is held by elastically locking the locking part 10 formed on the part .

  As is clear from the above description, according to the present invention, it is possible to provide a handrail headboard and a lighting unit excellent in workability, so that the handrail installation work can be simplified.

It is a principal part disassembled perspective view of the handrail headboard which concerns on this invention. It is a principal part longitudinal cross-sectional view which shows the installation structure of a handrail cap.

It is a principal part longitudinal cross-sectional view which shows the internal structure of a handrail cap, (a) is a figure which shows 2nd Embodiment, (b) is a figure which shows the modification.

  FIG. 1 shows a handrail B using a handrail cap A according to the present invention. In this embodiment, the handrail B has a bracket 21 attached to the handrail headboard A at a predetermined pitch, and is fixed to a wall surface 22 such as an outdoor staircase through the bracket 21 as shown in FIG.

  The bracket 21 includes an angle adjustment unit 23 that can adjust the attachment angle in accordance with the relative position with the handrail cap A, and is formed of an appropriate metal such as stainless steel. Specifically, a horizontal shaft portion 24 having one end fixed to the wall surface 22 and taking a horizontal posture, and a support shaft portion having one end connected to the horizontal shaft portion 24 and supporting the handrail headboard A by the other end. 25. The horizontal shaft portion 24 is a hollow member similar to a pipe. A decorative plate 24a is attached to the fixed end to the wall surface 22 in a flange shape, and a connecting portion 24b to the support shaft portion 25 is formed at the free end. . As shown in FIG. 2, the horizontal shaft portion 24 accommodates an anchor bolt 26 used for fixing to the wall surface 22 in a hollow interior.

  The connecting portion 24b includes a through hole (not shown) drilled in the direction orthogonal to the longitudinal direction with the same size as the outer diameter of the support shaft portion 25, and a female screw 27 that advances and retreats in the through hole by a rotating operation. Thus, the support shaft portion 25 inserted into the through-hole is connected to the support shaft portion 25 by pressing the support shaft portion 25 against the inner wall of the through-hole with the set screw 27. The horizontal shaft portion 24 described above is fixed to the wall surface 22 in a posture in which the through hole is oriented substantially in the vertical direction, but can be fixed by adjusting the direction of the through hole in accordance with the site if necessary.

  On the other hand, the support shaft portion 25 is formed in a bowl shape, and can swing about the same axis as the longitudinal direction of the horizontal shaft portion 24 at the tip portion opposite to the connecting end with the horizontal shaft portion 24. A head swing portion 25a is formed. As shown in FIG. 2, the swinging portion 25 a is connected to the main body portion 25 b by a screw 29, can swing around the screw 29, and maintains a predetermined swinging angle by tightening the screw 29. can do. An attachment piece 30 that is formed in a long plate shape in a direction orthogonal to the longitudinal direction of the support shaft portion 25 and is screwed to the cap lumber 2 is fixed to the tip of the above swinging portion 25a.

  Therefore, after fixing the horizontal shaft portion 24 to the wall surface 22 with the anchor bolt 26 at a predetermined pitch in accordance with the planned installation position of the handrail headboard A, the support shaft portion 25 is attached to the horizontal shaft portion 24, and then the swinging portion 25a. When the attachment piece 30 is attached to the handrail headboard A with screws 31 as shown in FIG. 2 with the screws 29 loosened, the swinging portion 25a functioning as the angle adjusting portion 23 swings and the brackets 21, 21,. -Absorbing a slight misalignment between them, all the brackets 21 can be firmly connected to the handrail headboard A. Thereafter, if the screw 29 of the swinging portion 25a is tightened, the swinging of the swinging portion 25a is prohibited, so that the handrail Kashiwagi A is firmly supported on the wall surface 22 through all the brackets 21, 21,. Is done.

  2 and the like, 32 is made of metal, and is inserted into a later-described groove (notch 1) of the handrail headboard A, and is interposed between the mounting piece 30 and the handrail headboard A. It is. This connection auxiliary member 32 is provided with a cable housing portion 32a in which a power supply cable 5 described later can be laid in the longitudinal direction, and is formed in a U-shaped cross-sectional shape in this embodiment. Reference numeral 33 denotes a fixing screw for fixing the connection auxiliary member 32 to the handrail headboard A.

  If the horizontal shaft portion 24 can be rotated by temporarily loosening the anchor bolt 26 or the like, the connecting portion 24b between the horizontal shaft portion 24 and the support shaft portion 25 can also function as the angle adjusting portion 23. Thus, it is possible to absorb a larger displacement between the brackets 21, 21,.

  On the other hand, the handrail headboard A is formed by fixing the lighting unit 3 to the headboard wood 2, and the lighting unit 3 illuminates both the tread surface of the stairs and the wall surface 22 to which the bracket 21 is fixed. As described above, since the brackets 21 are connected to the handrail headboard A at a predetermined pitch, the lighting unit 3 is provided between the brackets 21 and 21 that avoid the connection position with the bracket 21 over almost the entire length of the headboard 2. Placed in.

  The cap lumber 2 is formed into a substantially cylindrical shape by bending an appropriate metal plate such as stainless steel. In this embodiment, a glass top rail installed on a veranda is used. The shaded wood 2 has a circular cross section excluding the formation region of the concave groove 1 on the lower surface side. Moreover, since it is manufactured by bending, the central portion in the width direction of the bottom wall 2a of the groove 1 is a seam between the edges of the material plate.

  The illumination unit 3 is formed by holding a light source unit 4 and a power supply cable 5 in a case 7 as shown in FIG. The case 7 is formed of a material that is not so difficult to cut, such as a synthetic resin material, and that also has appropriate elasticity. The case 7 includes an engagement wall 6 having a U-shaped cross section, and is fixed to the shade wood 2 by engaging the outer surface of the engagement wall 6 with the inner wall of the groove 1 described above. At the time of fixing to the cap lumber 2, the ceiling portion of the engagement wall 6 is fixed to the bottom wall 2 a of the concave groove 1 with screws 34 at both ends in the longitudinal direction, and the engagement wall 6 is connected to the intermediate wall in the longitudinal direction. It is filled with an adhesive (not shown) between the concave grooves 1. In addition, since there is a seam of the cap wood 2 as described above, the screwing of the case 7 is not at the center in the width direction but at a position biased to one side.

  Further, the case 7 includes a light source holding part 35 and a cable holding part 36 that are provided side by side in the width direction. The light source holding portion 35 is disposed on the side of the wall surface 22 inside the engaging wall 6, and includes a sandwiching piece 37 that hangs down from the center in the width direction of the ceiling portion 6 a and a side wall 6 b on the wall surface 22 side of the engaging wall 6. Thus, the light source unit 4 is sandwiched. At the same height position on the front end of the holding piece 37 and the side wall 6b on the wall surface 22 side, a protrusion 38 for increasing the contact pressure is formed.

  On the other hand, the cable holding portion 36 is disposed on the staircase side inside the engagement wall 6, and is a cable extending inwardly from the lower end edge of the side wall 6 c on the staircase side of the engagement wall 6. The power supply cable 5 is supported by the support piece 9. The cable support piece 9 is formed to have a length such that the tip reaches the central portion in the width direction of the case 7, and the folded piece 39 can pass through the power feeding cable 5 between the holding piece 37 at the tip. It is erected at a height enough to separate the gaps.

  The light source unit 4 is formed by housing a strip-shaped printed circuit board 12 on which LEDs (point light sources 8, light emitting elements 13) are mounted at a predetermined pitch in a light transmissive housing case 4a. The printed circuit board 12 is a thin substrate such as a flexible circuit board, and the wiring is connected to the LED 8 (13) in parallel, so that both ends of the printed circuit board 12 are cut at appropriate positions in the longitudinal direction. It is made possible to supply power to all of the mounted LEDs 8 (13). Further, the LED 8 (13) is of a so-called surface emitting type, and the arrangement pitch is appropriately determined in consideration of the light quantity and the like.

  Further, the housing case 4a is formed of a synthetic resin material. The housing case 4a is formed to have a size that can accommodate the printed circuit board 12 therein, specifically, a hollow rectangular cross-sectional shape that is wide in the width direction of the printed circuit board 12, and is formed with a small thickness. It is easy to cut using an appropriate tool such as a nipper, and the length can be easily adjusted. The width dimension of the housing case 4a is set to be slightly larger than the distance between the holding piece 37 and the side wall 6b on the wall surface 22 side of the engaging wall 6 in the case 7 described above.

  On the other hand, the power supply cable 5 is formed to have the same length as that of the headwood 2, that is, the handrail headboard A.

  The handrail cap A described above cuts the case 7, the printed circuit board 12, and the housing case 4 a in accordance with the spacing between the brackets 21, 21 at the construction site, and the feeding cable 5 is slightly longer than the total length of the cap lumber 2. After cutting to the extent, these are formed by assembling the cap lumber 2 sequentially. The handrail headboard A is connected to the bracket 21 described above after the lighting unit 3 is assembled to the headwood 2. The bracket 21 is fixed to the wall surface 22 prior to the lighting unit 3 being assembled to the headwood 2. By doing so, the connection position with the bracket 21 can be confirmed to some extent accurately in advance. Prior to this assembly, an appropriate connection cable 40 is electrically connected to the wiring at both ends of the printed circuit board 12.

  Assembling, first, the case 7 is inserted and fixed in the recessed groove 1 of the cap lumber 2 in a position range corresponding to the brackets 21, 21, and then the light source unit 4 is attached to the case 7. Since the width dimension of the light source unit 4 is slightly larger than the distance between the sandwiching piece 37 and the side wall 6b on the wall surface 22 side of the engaging wall 6, the light source unit 4 while the sandwiching piece 37 is slightly bent by the pushing operation between them. Pinch. Further, at the time of the pushing operation, the posture of the connecting cable 40 described above is adjusted so that the free end hangs outside the case 7, that is, outside the concave groove 1.

  Thereafter, the free end of the connection cable 40 is electrically connected to the power feeding cable 5 outside the handrail headboard A. In this connection, the connection position in the longitudinal direction is adjusted according to the expected position when the power supply cable 5 is held by the cable holding portion 36.

  When the connection between the power supply cable 5 and the connection cable 40 is completed, the power supply cable 5 is finally inserted into the groove 1 and placed on the cable support piece 9, and both ends thereof are connected to the both ends of the cap lumber 2. It is pulled out from the appropriate part such as the cap 2 to the outside. When the assembly of the lighting unit 3 to the headwood 2 is completed as described above and the handrail headboard A is completed, it is attached to the bracket 21. When assembled to the bracket 21, the connection auxiliary member 32 is attached in the concave groove 1 so that the power supply cable 5 is accommodated in the cable accommodating portion 32 a. Further, when the assembly to the bracket 21 is completed, finally, the both ends of the power supply cable 5 are pulled out to the inside of the wall surface 22 through appropriate holes and connected to a commercial power source or a battery via the power control unit. B is completed.

  When power is supplied to the lighting unit 3, the illumination light from the LED 8 (13) disposed at a position slightly closer to the wall surface 22 inside the handrail headboard A is below the handrail headboard A as shown by a two-dot chain line in FIG. The area near the wall surface 22 is illuminated, so that the lower part of the wall surface 22 and the area near the handrail B on the tread surface of the stairs become bright even at night.

  Further, in this embodiment in which the step surface of the staircase described above is mirror-finished, in order to prevent the illumination light of the LED 8 (13) from being reflected in the step surface in a granular manner, the light diffusion plate 11 is attached to the handrail headboard A. Is done. As shown in FIG. 3, the light diffusing plate 11 is formed in a band shape in this embodiment, and groove-like locked portions 11 a for attaching to the case 7 are formed on both side edges thereof. The light diffusing plate 11 is formed, for example, by mixing a light transmissive synthetic resin material with a light diffusing agent and molding it.

  On the other hand, in the case 7 described above, the locking portion 10 protruding from the tip of the cable support piece 9 toward the light source unit 4 and the lower end edge of the side wall 6b on the wall surface 22 side of the engaging wall 6 are connected to the locking portion 10. A second locking portion 41 that protrudes toward the locking portion 10 is formed, and the locking portion 10 and the second locking portion 41 are locked to the locked portion 11a described above, whereby the light diffusing plate 11 is moved to the case 7. Retained.

  When attaching the light diffusing plate 11 to the case 7, first, the light diffusing plate 11 is inclined and the locked portion 11 a is locked only to the second locking portion 41, and then toward the locking portion 10. Is caused by When the light diffusing plate 11 is caused, the locking portion 10 interferes with the side edge of the light diffusing plate 11, so that the locking portion 10 deflects the side edge of the light diffusing plate 11 while bending the cable support piece 9. If the light diffusing plate 11 is further raised from here, the locking portion 10 is elastically locked to the locked portion 11a when the locking portion 10 faces the locked portion 11a.

  By attaching the light diffusing plate 11 to the handrail headboard A as described above, the illumination light illuminates a wider range as compared with the case where the light diffusing plate 11 is not attached as shown in FIG. Further, since the light source unit 4 is held at a deep position of the case 7 and a certain distance is secured between the light diffusion unit 11 and the light diffusion plate 11, the light diffusion function works very well. Furthermore, the light diffusing plate 11 is attached so as to be inclined so as to face the staircase side, so that the illumination range of the tread surface is further expanded.

  In addition, although the case where the light-diffusion plate 11 was used was shown above, if the light-diffusion plate 11 is not used as shown in FIG.3 (b), it can illuminate brighter, suppressing the loss of light quantity.

  FIG. 4A shows a second modification. In addition, in this modified example and other embodiments described later, the same elements as those in the above-described embodiment are denoted by the same reference numerals in the drawings, and description thereof is omitted. This modification corresponds to the case where the wall surface 22 described above is configured by a fence or the like, and the illumination light that irradiates the wall surface 22 side may leak to the lower floor side.

  In this modification, the printed circuit board 12 is formed to have a narrower width dimension such as the height dimension of the housing case 4a described above, and the light source unit 4 is such that the housing case 4a is rotated 90 degrees from the previous embodiment. It is held in the case 7 in a posture. The printed circuit board 12 is appropriately fixed to the inner wall surface 22 located above the housing case 4a with an adhesive or the like.

  The case 7 is shared with the previous embodiment, and the side wall 6b on the wall surface 22 side of the engaging wall 6 has a housing case 4a other than the position facing the protrusion 38 of the holding piece 37 described above. A protrusion 38 is formed at a position opposite to the vicinity of the lower end of the protrusion. In the holding of the light source unit 4 by the case 7 described above, an appropriate stuffing 42 is provided between the holding piece 37 and the side wall 6b on the wall surface 22 side to secure the holding state.

  Therefore, in this modification, since the LED 8 (13) is disposed closer to the wall surface 22, the wall surface 22 side by the side wall 6b on the wall surface 22 side of the engagement wall 6 of the case 7 or the second locking portion 41 is provided. The light path diffusing into the light is blocked, and illumination is performed with the tread surface alone as the center. Thereby, it is suppressed that illumination light leaks to the lower floor side as described above, and it becomes difficult to feel dazzling when looking up from the lower floor side. Further, since the lighting range can be changed by changing the light source unit 4 and adding the padding 42 as described above, the versatility of the handrail cap A is also improved.

  Even when the arrangement of the light source units 4 is changed in this way, if the light diffusing plate 11 is attached as shown in FIG. 4B, the reflection of illumination light on the tread surface can be suppressed, or the illumination range can be reduced. Can be widened to some extent. In addition, when arrange | positioning LED8 (13) closer to the wall surface 22 side of the engaging wall 6 as mentioned above, after making LED8 (13) in embodiment mentioned above into a side emission type, It is sufficient to rotate the posture by 90 degrees. Further, instead of stuffing the stuffing 42, it is sufficient to form only the housing case 4a as wide as appropriate.

  FIG. 5A shows a second embodiment of the present invention. In this embodiment, the case 7 has a short side wall 6b on the wall surface 22 side of the engagement wall 6 and a gap between the wall surface 22 and the inner wall of the groove 1 when fixed to the groove 1. It is formed. In addition, the opposite side wall 6c is formed in an inwardly convex arch shape. Further, in place of the above-described folded piece 39, the locking portion 10 is formed in an arc shape that is convex toward the cable holding portion 36 and has a slightly lower height than the folded piece 39.

  The light diffusing plate 11 has a convex portion 43 that is engaged with the locking portion 10 in a mounted state on one side surface thereof, and has a certain amount of width on the opposite side surface, and the inner wall of the engaging wall 6. A flat surface portion 44 that can be closely attached to is formed. A pressing wall 45 is formed above the convex portion 43 to prevent the power feeding cable 5 placed on the cable support piece 9 from being inadvertently shifted to the light source unit 4 side due to vibration or the like. .

  Further, in this embodiment, the light diffusing plate 11 is milky white as a synthetic resin agent mixed with the light diffusing agent. In addition, in the region on the wall surface 22 side, a shielding portion 46 that blocks the irradiation light irradiated on the wall surface 22 side is formed in a range substantially the same as the second locking portion 41 described above. Specifically, the shielding portion 46 is configured by forming a slit into the light diffusing plate 11 for reflecting a reflective material such as an aluminum foil. Therefore, in this embodiment, assembly workability is further improved.

  Moreover, in the above 2nd Embodiment, the light source unit 4 is formed wide like the above-mentioned embodiment, and LED8 (13) is arrange | positioned in the width direction of the shade wood 2 slightly toward the center. As shown in FIG. 4B, the light source unit 4 can be narrowed and the LED 8 (13) can be arranged closer to the side edge as shown in FIG. 4B. In this modification, the handrail cap A is configured using the same components as those of the second embodiment described above except for the light source unit 4.

  In this modification, the light source unit 4 is formed to have a width and a height that can be sandwiched between the side wall 6b and the pressing wall 45 by appropriately bending the side wall 6b of the engagement wall 6 on the wall surface 22 side. The In addition, a transparent synthetic resin material is used for the base material of the light diffusing plate 11 in order to suppress a decrease in the amount of light. Therefore, in this modification, even if the light source unit 4 is changed, the padding 42 does not need to be used separately as described above, and therefore versatility is further improved. In other words, according to the above second embodiment and its modification, the versatility of the case 7 is greatly improved. In addition, since the engaging recessed part 47 engaged with the lower end part of the light source unit 4 between the press wall 45 is formed in the upper surface of the light diffusing plate 11, the light source unit 4 is the wall surface 22 of the engaging wall 6. It is not pushed down by the side wall 6b on the side.

  In the above, the case where the handrail headboard A is attached to the wall surface 22 using the bracket 21 is shown. However, it is also possible to attach the handrail headboard A to the tread surface using an appropriate handrail support column. It is only necessary to connect it to a commercial power supply etc. after pulling it out to the space below the stairs through the handrail column.
