[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-046600 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, a wiring storage section for power lines and communication lines is formed on the back surface of the base, and a wiring outlet section is formed on the top surface or side surface of the base. However, in the above-mentioned conventional technology, since the base supports a heavy object via a support, a high-strength plate material is required on the top surface of the base, and further, a high-strength framework (e.g., a cross member and a frame) is required to support the plate material, which makes the device heavy and expensive.

[0005] The present invention has been made in consideration of the above circumstances, and has an object to provide a lightweight, inexpensive fixture that increases the strength of a flat base member while ensuring wiring space. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. (1) A fixture according to one embodiment of the present invention comprises a flat base member having a wheel portion attached thereto, the base member comprising an upper plate portion forming an upper surface, and a reinforcing member attached to the underside of the upper plate portion and forming a closed cross-section together with the upper plate portion, at least one of the sides of the upper plate portion and the reinforcing member being provided with a communication port capable of communicating with a space formed by the closed cross-section, and a cable is wired into the space through the communication port.

[0007] According to this aspect, the strength of the flat base member can be increased by attaching a reinforcing member to the underside of the upper plate portion and forming a closed cross section with the upper plate portion and the reinforcing member. This allows the flat base member to be inexpensively formed from a thin plate as a whole. Furthermore, since there is a communication port leading to the space formed by the closed cross section, the space can be used as a wiring space, and wiring can be passed through the inside of the base member without providing any additional members other than the reinforcing member.

[0008] (2) In the fixture relating to the above aspect (1), the communication opening is provided at least in the upper plate portion, and the reinforcing member has a pair of flange portions that narrow the opening width of the communication opening when attached to the underside of the upper plate portion, and may have a cover member placed on the pair of flange portions exposed from the communication opening and closing the communication opening. According to this aspect, the lid member is placed across the pair of flange portions of the reinforcing member at the communication opening of the upper plate portion, so that the communication opening of the upper plate portion can be closed by the lid member without providing any additional members other than the reinforcing members.

[0009] (3) In the fixture relating to the above aspect (2), the reinforcing member may include a bottom wall portion facing the underside of the upper plate portion with a gap therebetween, a pair of side wall portions extending from opposite side edges of the bottom wall portion toward the upper plate portion, and the pair of flange portions extending from upper ends of the pair of side wall portions in directions away from each other. According to this embodiment, the cross section of the reinforcing member is hat-shaped (approximately U-shaped, approximately inverted Ω-shaped), making it easy to secure wiring space inside, and the presence of a pair of flanges makes it easy to fix the reinforcing member to the underside of the upper plate portion.

[0010] (4) In a fixture relating to any one of the above aspects (1) to (3), a hollow support portion is provided upright on the upper plate portion, and the cable may extend from inside the support portion through the communication opening to the space. According to this aspect, when a specified electrical device, such as a light, is installed on the support pole, a cable can be passed inside the support pole and then through the space formed by the upper plate and the reinforcing member, so that the cable can be wired without being exposed, improving the design.

[0011] (5) In the fixture relating to any one of the above aspects (1) to (4), an electrical equipment mounting portion may be provided on the underside of the upper plate portion at a location different from the reinforcing member in which the communication hole is provided. According to this aspect, since the electrical device can be attached to the underside of the upper plate, the appearance of the base member is neat, and a cable can be connected to the electrical device through the communication port on the underside of the upper plate. Examples of the electrical device include a voltage converter, a storage battery, and a lighting control device.

[0012] (6) In the fixture according to any one of the above aspects (1) to (5), the communication openings may be provided opposite each of a pair of the side surfaces of the reinforcing member. According to this aspect, the cable can be routed not only in the longitudinal direction of the reinforcing member, but also through a side surface of the reinforcing member and passed through to the opposite side. Effect of the Invention

[0013] According to each of the above aspects, it is possible to provide a lightweight, inexpensive fixture by increasing the strength of the flat base member while ensuring wiring space. [Brief description of the drawings]

In addition, with regard to "up," "down," "left," and "right," the direction indicated by the arrow UP in the drawings will be referred to as "up" and the opposite direction will be referred to as "down," the direction indicated by the arrow LH in the drawings will be referred to as "left" and the opposite direction will be referred to as "right."

[0016] FIG. 1 is a perspective view of a fixture 1 according to this embodiment. As shown in Fig. 1, the fixture 1 of this embodiment includes a flat base member 10 and a frame body 20 supported by the base member 10. A lighting device 30 is attached to the frame body 20. A cover member 40 that closes the communication opening 12 of the upper plate portion 11 is placed on the base member 10.

[0017] The frame 20 includes a pair of support columns 21 and a plurality of beams 22, 23 connecting the pair of support columns 21. The pair of support columns 21 are erected on the upper plate 11 of the base member 10 with a gap therebetween in the left-right direction. The lower ends of the pair of support columns 21 are fixed to the base member 10 while penetrating the upper plate 11.

[0018] The beam portion 22 extends in the left-right direction and connects the upper ends of the pair of support portions 21 to each other. The beam portion 23 extends in the left-right direction at a position lower than the beam portion 22 and connects the vicinity of the upper ends of the pair of support portions 21 to each other. A frame portion 24 that is U-shaped in plan view is attached facing forward from the connection position of the beam portion 22 on the pair of support portions 21.

[0019] An illumination device 30 is attached to the lower surface of the frame 24. The illumination device 30 includes a plurality of light sources such as LEDs. A partition member illuminated by the illumination device 30 may be attached to the frame 20. The electrical device attached to the frame 20 is not limited to the illumination device 30, and a display device or the like may be attached.

[0020] Fig. 2 is a plan view of the fixture 1 according to this embodiment. Fig. 3 is a plan view of the fixture 1 with the cover member 40 shown in Fig. 2 removed. Fig. 4 is an enlarged partial cross-sectional view of a main part of the right side surface of the fixture 1 according to this embodiment. 2, the base member 10 includes an upper plate portion 11 having a rectangular shape in a plan view with the longitudinal direction being the left-right direction. The upper plate portion 11 forms an upper surface 11a of the base member 10. The upper plate portion 11 in this embodiment is formed in a cylindrical shape with a top.

[0021] Wheel units 13 are disposed at the four corners of the upper plate portion 11. The wheel units 13 are attached to the lower surface 11b side of the upper plate portion 11, as shown in Fig. 4. A reinforcing member 50 is disposed in the center of the upper plate portion 11 in the front-rear direction. The reinforcing member 50 is attached to the lower surface 11b of the upper plate portion 11.

[0022] Specifically, the reinforcing member 50 includes a bottom wall portion 51 facing the lower surface 11b of the upper plate portion 11 with a gap therebetween, a pair of side wall portions 52 extending from both side edges of the bottom wall portion 51 toward the upper plate portion 11, and a pair of flange portions 53 extending in directions away from each other from upper ends of the pair of side wall portions 52. The reinforcing member 50 has a hat-shaped (approximately U-shaped, approximately inverted Ω-shaped) cross section.

[0023] The reinforcing member 50 is joined by spot welding the upper surfaces of a pair of flanges 53 to the lower surface 11b of the upper plate portion 11. The pair of flanges 53 are slightly bent in a crank shape. The pair of flanges 53 may be fixed to the upper plate portion 11 using, for example, screws and nuts, but since the screws and nuts are exposed on the upper surface 11a of the upper plate portion 11, it is preferable to join the flanges by spot welding or the like in consideration of appearance.

[0024] The upper plate 11 and the reinforcing member 50 form a substantially rectangular closed cross section, as shown in Fig. 4. The upper plate 11 is formed with a communication port 12 (see Figs. 2 and 3) that can communicate with the space S formed by the closed cross section. In addition, the side surface of the reinforcing member 50 is formed with a communication port 54 (see Figs. 2 and 3) that can communicate with the space S formed by the closed cross section.

[0025] As shown in Figures 2 and 3, the communication opening 12 is formed in the center of the upper plate portion 11 in a plan view. The communication opening 12 is formed in a rectangular shape in a plan view with the longitudinal direction being the left-right direction. As shown in Figure 3, the communication opening 12 has an opening width W1. The opening width W1 refers to the dimension of the communication opening 12 in the short direction.

[0026] The reinforcing member 50 has a pair of flanges 53 that narrow the opening width W1 of the communication opening 12 to an opening width W3 when attached to the lower surface 11b of the upper plate portion 11. In other words, a part of the upper surface of the pair of flanges 53 is exposed from the communication opening 12. The cover member 40 is placed on the pair of flanges 53 exposed from the communication opening 12, and closes the communication opening 12 as shown in FIG.

[0027] The cover member 40, like the communication port 12, is formed in a rectangular shape in plan view with the left-right direction as the longitudinal direction. A pair of notches 41 that can be hooked with fingers to lift the cover member 40 are formed at both left-right ends of the cover member 40. The pair of notches 41 are formed in a semicircular shape in plan view. In addition, a pair of alignment projections 42 that can be positioned between a pair of flanges 53 are formed on the underside of the cover member 40.

[0028] 2 and 3, a plurality of communication openings 54 are formed in the reinforcing member 50. The reinforcing member 50 extends in the left-right direction on the lower surface 11b side of the upper plate portion 11 with substantially the same length as the upper plate portion 11. In this embodiment, two communication openings 54 are formed at the left end portion of the reinforcing member 50, and one communication opening 54 is formed at the right end portion of the reinforcing member 50. The arrangement and number of the communication openings 54 are not limited to this embodiment.

[0029] The communication openings 54 are formed by cutting out the side wall portions 52 and the flange portions 53 of the reinforcing member 50. The communication openings 54 may be formed by penetrating the side wall portions 52 without cutting out the flange portions 53. The communication openings 54 are formed at least at both left and right ends of the reinforcing member 50 in locations close to the lower ends of the pair of support portions 21.

[0030] A cable 60 is disposed inside the pair of support pillars 21. The cable 60 is connected to the lighting device 30 shown in Fig. 1. This cable 60 extends from an opening at the lower end of the support pillars 21 or an opening (not shown) on the side surface of the lower end to the space S via a communication port 54. In addition, this cable 60 extends from the communication port 54 formed on the front side surface of the reinforcing member 50 to an electric device 71 attached to the electric device attachment portion 70.

[0031] The electrical device mounting portion 70, like the reinforcing member 50, has a hat-shaped (approximately U-shaped or inverted Ω-shaped) cross section and is fixed to the lower surface 11b of the upper plate portion 11. Electrical devices 71 such as a voltage converter, a storage battery, and a lighting control device are attached to the electrical device mounting portion 70. Note that the electrical device 71 in this embodiment is a lighting control device including a power source, and the lighting device 30 is connected to the electrical device 71 via a cable 60 and is configured to operate by receiving power from the electrical device 71.

[0032] As shown in Figure 4, the fixture 1 of the above configuration comprises a flat base member 10 having wheel portions 13 attached thereto. The base member 10 comprises an upper plate portion 11 forming an upper surface 11a, and a reinforcing member 50 attached to a lower surface 11b of the upper plate portion 11 and forming a closed cross-section together with the upper plate portion 11. At least one of the side surfaces of the upper plate portion 11 and the reinforcing member 50 is provided with communication openings 12, 54 that can communicate with a space S formed by the closed cross-section, and a cable 60 is wired into the space S through the communication opening 54.

[0033] According to this configuration, the strength of the flat base member 10 can be increased by attaching the reinforcing member 50 to the lower surface 11b of the upper plate portion 11 and forming a closed cross section with the upper plate portion 11 and the reinforcing member 50. This allows the flat base member 10 to be formed inexpensively from a thin plate as a whole. Furthermore, since there are communication openings 12, 54 leading to the space S formed by the closed cross section, the space S can be used as a wiring space, and wiring can be passed through the inside of the base member 10 without providing any additional members other than the reinforcing member 50.

[0034] In addition, in this embodiment, as shown in Figures 2 and 3, the communication opening 12 is provided at least in the upper plate portion 11, and the reinforcing member 50 has a pair of flange portions 53 that narrow the opening width of the communication opening 12 when attached to the lower surface 11b of the upper plate portion 11, and is provided with a cover member 40 that is placed on the pair of flange portions 53 exposed from the communication opening 12 and closes the communication opening 12. According to this configuration, the cover member 40 is placed across a pair of flange portions 53 of the reinforcing member 50 at the communication opening 12 of the upper plate portion 11, so that the communication opening 12 of the upper plate portion 11 can be closed by the cover member 40 without providing any additional members other than the reinforcing member 50.

[0035] In addition, in this embodiment, as shown in Figure 4, the reinforcing member 50 includes a bottom wall portion 51 facing the lower surface 11b of the upper plate portion 11 with a gap therebetween, a pair of side wall portions 52 extending from both side edges of the bottom wall portion 51 toward the upper plate portion 11, and a pair of flange portions 53 extending from the upper ends of the pair of side wall portions 52 in directions away from each other. With this configuration, the cross section of the reinforcing member 50 is hat-shaped (approximately U-shaped, approximately inverted Ω-shaped), making it easier to secure wiring space inside, and the presence of a pair of flange portions 53 makes it easier to fix the reinforcing member 50 to the underside 11b of the upper plate portion 11.

[0036] In this embodiment, as shown in FIGS. 2 and 3, a hollow support portion 21 is provided standing on the upper plate portion 11, and the cable 60 extends from inside the support portion 21 to the space S through the communication port 54. According to this configuration, when a specified electrical device, such as a lighting device 30, is installed on the support portion 21, the cable 60 can be passed inside the support portion 21 and then through the space S formed by the upper plate portion 11 and the reinforcing member 50, so that the cable 60 can be wired without being exposed, improving the design.

[0037] In this embodiment, as shown in Figs. 2 and 3, an electric device attachment portion 70 is provided on the lower surface 11b side of the upper plate portion 11 at a location different from the reinforcing member 50 where the communication port 54 is provided. According to this configuration, the electrical equipment 71 can be attached to the underside 11b of the upper plate portion 11, thereby giving the base member 10 a neat appearance and allowing a cable 60 to be connected to the electrical equipment 71 through the communication openings 12, 54 on the underside 11b of the upper plate portion 11.

[0038] Thus, according to this embodiment, it is possible to provide a lightweight and inexpensive fixture 1 by increasing the strength of the flat base member 10 while ensuring wiring space.

[0039] Furthermore, the fixture 1 of this embodiment can adopt the following configuration.

[0040] FIG. 5 is a perspective view of a reinforcing member 50 according to a modified example of this embodiment. 5, the communication openings 54 may be provided facing each other on a pair of side surfaces of the reinforcing member 50. With this configuration, the cable 60 can be routed not only in the longitudinal direction of the reinforcing member 50, but also through the side surface of the reinforcing member 50 and passed to the opposite side.

[0041] 5, the cable 60 passes through three reinforcing members 50 in the short direction, but it may pass through only one reinforcing member 50. Also, the cable 60 that passes through one reinforcing member 50 may enter an adjacent reinforcing member 50 and be wired therein in the longitudinal direction.

[0042] Although the preferred embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the above embodiment. The shapes and combinations of the components shown in the above embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0043] For example, in the present embodiment, the cable 60 has been described as extending from the inside of the support portion 21 to the space S through the communication opening 54, but, for example, the cable 60 may extend from the side surface of the support portion 21 to the space S through the communication opening 12. In this case, the cable 60 may pass through a notch 41 formed in the cover member 40. This makes it possible to pass the cable 60 from the inside to the outside of the base member 10 with the cover member 40 closing the communication opening 12.

[0044] Also, for example, a reinforcing member 50 having a communication opening 54 and a reinforcing member 50 not having a communication opening 54 may be attached to the lower surface 11b of the upper plate portion 11. [Explanation of symbols]
