Description

  The present invention relates to an illuminating device that illuminates the stairs when the stairs are raised and lowered, and more particularly, to a remodeling illuminating device that can be mounted on each step plate of an existing stairs and economically lit, and its mounting structure.

  2. Description of the Related Art Conventionally, when ascending / descending a stairs at night or the like, the stairs are illuminated to ensure safety. As such an illuminating device, lighting a plurality of small lighting fixtures embedded in the side wall of the staircase, or making the lighting a night light because it is difficult to find a lighting switch in the dark, or even A human body detection sensor is used to light up. However, such an illuminating device is uneconomical because it is configured to illuminate the entire staircase and cannot intensively illuminate the feet.

For this reason, for example, as described in Patent Document 1, a step board of a staircase is formed in a hollow shape, a light source for illuminating a foot is disposed in the hollow, and a human body is provided on the uppermost step side and the lowermost step side of the staircase. As described in Japanese Patent Application Laid-Open No. 2003-28109, a lighting device is provided that includes a detection sensor and is configured to irradiate light from these light sources toward the feet by operating the light source by the human body detection sensor when moving up and down. A recess is provided in each step of the step, and a tread is disposed in the recess via a pressing power generation element, and a light emitting diode is provided in the vicinity of the tread, and the pressing power generation element and these light emitting diodes are connected via a power storage device. Thus, an illuminating device has been developed in which an electromotive force is generated in a pressing power generation element when a treadle is stepped on and a light emitting diode is turned on via the power storage device.

  However, according to the illuminating device described in Patent Document 1, it is not only necessary to energize the human body detection sensor or the like at all times, but also it is configured to illuminate the light sources from all the treads when moving up and down. Therefore, this lighting device is not preferable from the viewpoint of energy saving.Furthermore, since this lighting device has a tread plate formed in a hollow and a light source or the like is disposed in the hollow, when reforming an existing staircase, There is a problem that this lighting device cannot be attached to each tread.

  On the other hand, according to the illuminating device described in Patent Document 2, it is possible to light only an arbitrary tread board and a light emitting diode disposed on a tread board adjacent to the top and bottom of the tread board when moving up and down, which contributes to energy saving. However, similar to the lighting device described in Patent Document 1, the step board of each step of the staircase is different from the normal step board of the staircase and has a special portion provided with a recess or the like in which a pressing power generation element or the like can be provided. Since it is structured in shape and shape, it is necessary to remove all the treads on this staircase and replace them with treads having the above-mentioned structure in order to renovate the existing staircase, and newly provide light emitting diodes. There was a problem that the necessity of the construction was large and the construction period was long, and the construction cost was high, which was not suitable for renovation in practice.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is that it can contribute to energy saving, as well as excellent handling and construction, and with respect to existing stairs. Further, the present invention provides a stair illuminating device that can be easily transformed into a stair that can be illuminated using the stair tread as it is, and a mounting structure for the stair illuminating device.

  In order to achieve the above object, a renovation stair illuminating device according to the present invention is a flexible tread laid on a tread surface of each tread of an existing staircase via a cushion material as described in claim 1. A covering plate, a piezoelectric element attached to the lower surface of the tread plate covering plate and generating electric power by bending deformation of the tread plate covering plate, and the front end surfaces of the step plate covering plate from the nose tip to the tip of the tread plate covering plate. A nose covering member that is attached in a state where it is covered and has a plurality of holes in the lengthwise direction, and a nose covering member that is mounted in the back side space of the nose covering member and The light emitting diode is connected to the piezoelectric element through the wiring and facing the outside.

  In the renovation stair illuminating device configured as described above, the invention according to claim 2 is formed by engraving a plurality of straight grooves having a certain depth penetrating in the depth direction of the tread on the lower surface of the tread covering plate. Flexibility is given by the straight groove, and a decorative board is stuck on the upper surface of the tread board covering board.

  Furthermore, in the invention according to claim 3, the cushion material is integrally attached to the lower surface of the tread plate covering plate, and the central portion of the edge of the cushion material located on the nose side of the tread plate is excised. A piezoelectric element is attached to the lower surface of the tread plate covering plate exposed to the surface.

  According to a fourth aspect of the present invention, there is provided a mounting structure for the above-described renovation stair illuminating device, wherein a flexible tread board covering plate having a piezoelectric element attached to the lower surface is provided on a tread surface of each tread of an existing staircase. A nose covering member formed by piercing the nose tip of each tread plate with a plurality of through holes at intervals in the length direction from the nose tip of each tread plate to the tread plate covering plate. A light emitting diode is provided in a state where the front end surface is entirely covered over the front end, and further, a light emitting diode facing the outside from each through hole is disposed in the back side space portion of the nose covering member. These light emitting diodes are connected to the piezoelectric elements via wiring, and the light emitting diodes are turned on by deformation of the piezoelectric elements when the tread board covering plate is stepped on.

  In the renovation staircase lighting device mounting structure configured as described above, the invention according to claim 5 is a light emitting device disposed on a step board covering plate laid on an arbitrary step board. It is configured to light up the diodes and the light emitting diodes arranged on the stage located above and below this stage.

  According to the renovation staircase illumination device and its mounting structure of the present invention, a flexible treadboard covering plate with a piezoelectric element attached to the lower surface is laid on the tread surface of an existing staircase via a cushioning material. Since the front end surface of the tread board extends from the front end of the tread board to the front end of the tread board covering plate, the nose covering member on which the plurality of light emitting diodes are mounted is attached. The tread board covering material can be easily applied to the tread board through a cushioning material, and a plurality of light emitting diodes are mounted on the nose covering member. By attaching the nose covering member so as to integrally cover the front end surface of the covering plate, these light emitting diodes can be disposed at the same time, and therefore, the existing stair step plate is replaced. Processed without or can be performed with good efficiency the construction work of the present invention stairway lighting apparatus for the existing stairway.

  In addition, the stair illuminating device is composed of the tread plate covering plate having the piezoelectric element attached to the lower surface and the nose covering member having a plurality of light emitting diodes mounted thereon as described above, so the structure is simple and inexpensive. The light emitting diode is mounted in the space provided on the back surface of the nose covering member, and the nose covering member is fixed in the length direction. Since the light-emitting diodes are not exposed to the outside together with the piezoelectric elements attached to the lower surface of the tread plate cover plate, they are prevented from being damaged or broken because they are exposed to the outside through the through holes formed at every interval. Of course, it can be reformed into a staircase that has a good appearance that is almost the same as a normal tread board, and each light emitting diode and piezoelectric element can be transformed using the space on the back side of the nose covering member. Connection wiring between the child can also be easily performed without being exposed to the outside.

  Furthermore, the treadboard covering plate has flexibility, and since this treadboard covering plate is laid on the stepping plate of the existing staircase via the cushioning material, when the treadle covering plate is stepped on when raising or lowering the stairs, The tread board cover plate can be easily bent and deformed downward while compressing the cushioning material, and the deformation pressure can be directly transmitted to the piezoelectric element. The pressure generates electric power from the piezoelectric element so that the light emitting diode is reliably turned on. Since all the light-emitting diodes are exposed to the outside from the through holes provided in the nose covering member, the feet can be reliably illuminated by these light-emitting diodes, and the stairs can be raised and lowered safely Can do.

  In addition, since high temperature does not occur even when the light emitting diode is lit, heat treatment is not necessary, and it can be used until the luminous efficiency decreases, and it can be used for a long time compared to lighting equipment with ordinary electric light Thus, the maintenance cost is low. In addition, since it is configured to light up only when the stairs are raised and lowered, not only does the power storage device for stable power supply become unnecessary, but it also eliminates the possibility of unpleasant insects gathering like a nightlight. be able to.

  Furthermore, the nose covering member attached to the nose tip of each step plate of the existing staircase also exhibits a non-slip function and enables safer lifting and lowering, and the nose covering member and the step plate covering plate can be damaged. If a light emitting diode or the like breaks down, the stairs can be repaired easily and economically by replacing only the nose covering member or the tread board covering plate.

  In the above-described renovation stair lighting device, according to the invention according to claim 2, a large number of straight grooves of a certain depth penetrating in the depth direction of the tread plate are formed on the lower surface of the tread plate covering plate, and these straight shapes are formed. Because the groove gives flexibility to the tread plate cover plate, any part of this tread plate cover plate that is stepped on when moving up and down the staircase is distributed across the tread plate cover plate via the straight groove, and piezoelectric It is possible to reliably transmit to the element, and thus it is possible to generate stable power. Moreover, since the decorative board is affixed on the upper surface of this tread board coating | coated board, it can reform into the staircase structure which exhibits the outstanding external appearance.

  According to the invention of claim 3, since the cushion material is integrally attached to the lower surface of the tread board covering plate, the cushion material is not only easy to handle but also attached to the tread surface of the existing staircase. The tread board covering plate can be applied easily and accurately by wearing it, and the tread board covering plate exposed at the excised portion by cutting off the center edge of the cushion material located on the nose side of the tread board Since the piezoelectric element is attached to the lower surface, the piezoelectric element is disposed in the vicinity of the nose where it is most frequently stepped on when moving up and down, so that reliable power can always be generated stably.

  According to the invention of claim 5, when a tread board covering plate laid on an arbitrary step tread is stepped on, the light emitting diodes arranged in this step and the steps positioned above and below the step are arranged. Since the light emitting diodes arranged are lit, each time the step board cover plate of each step is stepped on, the electric power from the piezoelectric element attached to the lower surface of the step plate cover plate is Only the light emitting diodes arranged at the stage located in the center can be dispersed and supplied in a concentrated manner so that the light emitting diodes can be lit with a predetermined brightness, and the stage can be safely raised and lowered while checking the steps to be stepped on one after the other. be able to.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. In FIGS. 1 to 4, the renovation stair lighting device has the same planar shape as the tread surface of the tread B in each step of the existing staircase A. A flat tread cover plate 1 which is formed in a horizontally long rectangular shape and can cover the entire tread surface, a piezoelectric element 2 attached to the lower surface of the tread plate cover plate 1, and the piezoelectric element A light emitting diode (LED) 4 connected to the distal end of each wiring 3 via a plurality of wirings 3 whose base ends are connected to the electrodes of the element 2, and a constant attached to the lower surface of the tread plate covering plate 1 A cushion material 5 having a thickness and a nose tip of the step board B are attached from the nose tip of the step board B to the tip of the tread board covering plate 1 laid on the tread B. Multiple transparent parts at regular intervals in the vertical direction 7 consists nosing covering member 6 for being bored.

  Then, the wiring 3 connected to the piezoelectric element 2 is introduced into a space 8 (shown in FIGS. 2 and 3) provided on the back side of the nose covering member 6 and a plurality of light emitting diodes 4 are mounted. Each light emitting diode 4 is configured to face upward through the through-hole 7 and to be lit by electric power generated from the piezoelectric element 2.

  The renovation stair lighting device will be described in more detail. The tread board covering plate 1 is made of a plywood having a thickness of 9 mm and a decorative plate 9 made of natural wood veneer is attached to the entire upper surface. As shown, a straight groove 10 having a depth of 6 mm and a width of 1 mm from the lower surface to the upper surface is formed in the depth direction of the tread B, that is, between the base end surface and the front end surface of the tread plate covering plate 1. It penetrates and is engraved at a pitch interval of 10 mm in the longitudinal direction. These straight grooves 10 provide flexibility to the tread plate covering plate 1 and the upper half of the tip part over the entire length. A stepped portion 1a is formed by cutting out in an L-shaped cross section. The tread board covering plate 1 may be formed of a wood material other than the plywood, or may be formed of a synthetic resin material.

  Further, the depth, width, pitch, and the like of the straight groove 10 may be appropriately set according to the thickness and material of the tread board covering plate 1, and further, the straight groove 10 is formed as described above. However, it may be provided so as to be parallel to the long side. Further, in the case where a plate material that is flexible enough to transmit pressure due to bending deformation to the piezoelectric element 2 attached to the lower surface to generate electric power of the piezoelectric element 2, such a straight groove is used. 10 need not necessarily be provided.

  The cushion material 5 adhered to the entire lower surface of the tread plate cover plate 1 is made of a urethane resin foam having a thickness of 5 mm, and only a portion corresponding to the piezoelectric element 2 attached to the lower surface of the tread plate cover plate 1 is cut out. Thus, the piezoelectric element 2 is exposed from the cut portion 11 by cutting. In addition, this cushion material 5 may be formed from suitable resin foams, such as a polyethylene type, a polyester type, a phenol type other than a urethane-type resin foam.

  Further, the thickness of the cushion material 5 is not limited to 5 mm, and may be formed to a thickness of 1 mm to 10 mm according to the material or the like. If the thickness of the cushion material 5 is 1 mm or less, the amount of compression of the cushion material 5 is small when the tread board covering plate 1 adhered to the tread board B via the cushion material 5 is stepped on. The amount of bending deformation of the plate 1 is very small, and vibrations and pressures due to the bending deformation are difficult to be transmitted to the piezoelectric element 2 and stable power generation is not possible. On the other hand, when the thickness is 10 mm or more, the compression amount of the cushion material 5 increases. This is not preferable because the amount of bending deformation of the tread plate covering plate 1 is increased and the feeling of walking is not impaired, and pressure due to the bending deformation of the tread plate covering plate 1 is partially concentrated on the piezoelectric element 2 and is likely to break down.

  The piezoelectric element 2 is a bimorph type piezoelectric element formed by sticking a piezoelectric bimorph element to a central portion in the length direction of a rectangular printed board made of FRP resin.

The pressure due to the bending deformation of the tread board covering plate 1 is reliably transmitted to the piezoelectric element 2, and the power is always generated stably.

  In the cushion material 5, the central part of the long side edge on the nose side of the step board B is cut into a horizontally long rectangular shape which is the same as the planar shape of the piezoelectric element 2, and the piezoelectric element 2 is covered with the step board through the cut portion 11. The plate 1 is attached to the central portion of the long-side tip on the nose side. In the tread plate covering plate 1 in which the straight grooves 10 parallel to the long side are provided at regular intervals in the short side direction on the lower surface, as shown in FIG. Are provided with rectangular cut portions 11 and 11 which are long in the short direction of the cushion material 5, and through these cut portions 11 and 11, the piezoelectric elements 2 and 2 are formed into straight grooves at the center portions on both sides of the bottom surface of the tread plate cover plate 1. Just stick it in a state orthogonal to 10.

  The number of piezoelectric elements 2 attached to the lower surface of the tread plate covering plate 1 is not limited to one or two as described above. For example, the tread surface dimension is 200 mm to 220 mm, and the distance between the short side end surfaces on both sides is In the case of the tread B having a width of about 800 mm to 1000 mm, two or three piezoelectric elements 2 may be attached to each tread B. The piezoelectric element 2 employs a bimorph type piezoelectric element, but may employ a monomorph type or a laminated type piezoelectric element. Further, as the light emitting diode 4 connected to the piezoelectric element 2 via the wiring 3, an ultra-high brightness bullet-type piezoelectric element having a luminous intensity of 6800 mcd, a directivity of 15 °, and a rated DC forward current of 20 mA is used. Other light emitting diodes may be employed.
