[Modes for carrying out the invention]

[0009] Embodiments of this technology are described below. Note that the same or corresponding parts may be denoted by the same reference numerals, and their descriptions may not be repeated.

[0010] In the embodiments described below, when referring to the number, quantity, etc., unless otherwise specified, the scope of this technology is not necessarily limited to that number, quantity, etc. Also, in the embodiments described below, each component is not necessarily essential to this technology unless otherwise specified. Furthermore, this technology is not necessarily limited to achieving all of the effects and advantages mentioned in these embodiments.

[0011] In this specification, the terms "comprise," "include," and "have" are in open-ended form. That is, if a configuration includes one configuration, it may also include other configurations, or it may not.

[0012] Furthermore, where geometric terms and terms describing positional and directional relationships are used in this specification, such as "parallel," "orthogonal," "45° oblique," "coaxial," and "alongside," these terms allow for manufacturing tolerances or slight variations. Where terms describing relative positional relationships, such as "upper" and "lower," are used in this specification, these terms are used to indicate the relative positional relationship in a single state, and the relative positional relationship may be reversed or rotated to any angle depending on the installation direction of each mechanism (for example, by inverting the entire mechanism upside down).

[0013] Furthermore, the dimensions of each component illustrated in this specification, such as width, length, and diameter, are not limited to those shown and may be changed as appropriate. In this specification, each component may be assigned an ordinal number such as "1st" or "2nd," but these ordinal numbers do not limit priority, order, etc., unless explicitly specified.

[0014] In this specification, the "base portion" may be, for example, a construction sign (a plate-shaped member) or a single pipe (a tubular member). However, in the technical context, the "base portion" is not limited to construction components, but may also be, for example, a handlebar or frame member of a two-wheeled vehicle such as a bicycle, or a component of a general mechanical structure or fixed structure.

[0015] In this specification, the "device" or "construction equipment" fixed to the "base" may be, for example, a construction lighting device or a display device having a light-emitting display unit. However, the "device" or "construction equipment" is not limited to those having a "light-emitting unit". Furthermore, the "device" is not limited to construction equipment, and may be, for example, equipment for two-wheeled vehicles such as bicycles (cycle computers, etc.) or other general electronic devices.

[0016] In the drawings attached to this specification, the DR1 direction (first direction), the DR2 direction (second direction), and the DR3 direction (third direction) are substantially orthogonal to each other.

[0017] Figs. 1 and 2 are perspective view (Fig. 1) and side view (Fig. 2) of construction supplies 1 as an example of the present technology. The construction supplies 1 shown in Figs. 1 and 2 are signboard illuminations attached to a construction signboard.

[0018] As shown in Figs. 1 and 2, the construction supplies 1 include a lighting device 10 (construction equipment) and a fixture 20 for fixing the lighting device 10 to a construction signboard (base part).

[0019] The lighting device 10 has a pedestal 11, a housing 12, and a rotating part 13. The pedestal 11 can be detachably attached to the fixture 20. The pedestal 11 can be made of metal. The housing 12 includes a light-emitting part for lighting. The rotating part includes a rotation operation part 13A. By operating the rotation operation part 13A, the angle of the housing 12 with respect to the pedestal 11 can be changed. More specifically, by turning the rotation operation part 13A in the loosening direction, the housing 12 can be rotated around the axis in the DR3 direction with respect to the pedestal 11. Also, by turning the rotation operation part 13A in the tightening direction, the housing 12 is in a state where it does not rotate around the axis in the DR3 direction with respect to the pedestal 11.

[0020] The fixture 20 includes a first gripping part 21, a second gripping part 22, a shaft part 23, and a mounting part 24. The fixture 20 can be made of resin. Thereby, the weight of the fixture 20 can be reduced.

[0021] The first gripping part 21 and the second gripping part 22 sandwich the construction signboard (base part). The first gripping part 21 and the second gripping part 22 can sandwich the construction signboard in the DR1 direction (first direction). When the first gripping part 21 and the second gripping part 22 sandwich the construction signboard, they are located on opposite sides of the construction signboard in the DR1 direction (first direction).

[0022] The shaft portion 23 is rotatably mounted around an axis in the DR1 direction relative to the first gripping portion 21 and the second gripping portion 22. An operating portion 23A is provided on the front end side (first side) of the shaft portion 23. By rotating the operating portion 23A, the shaft portion 23 is rotated around the axis in the DR1 direction, causing the first gripping portion 21 to move in the DR1 direction. At this time, the second gripping portion 22 remains stationary. That is, in the DR1 direction, the first gripping portion 21 moves relative to the second gripping portion 22. The operating portion 23A may also be positioned on the rear end side (second side) of the shaft portion 23. The base 11 of the lighting device 10 is detachably fitted into the mounting portion 24. This allows the lighting device 10 to be attached to the fixing device 20.

[0023] Figures 3 through 7 are side views (Figure 3), top views (Figure 4), VV cross-sectional views in Figure 4 (Figure 5), front views (Figure 6), and rear views (Figure 7) of the fastener 20, respectively.

[0024] As shown in Figures 3 to 7, the fastener 20 includes a first member 210, a second member 220, a bolt member 230, a mounting member 240, and a nut 250.

[0025] The first member 210 constitutes the first gripping portion 21. A rib 211 is formed on the front end side of the first member 210, protruding from the bottom surface in the DR1 direction. The rib 211 is formed in a grid shape so as to extend in the DR2 and DR3 directions when viewed from the DR1 direction. However, the shape of the rib 211 is not limited to this. By providing the rib 211, the weight of the first member 210 can be reduced while ensuring the strength of the first gripping portion 21. A nut 212 is attached to the first member 210.

[0026] The second member 220 is formed in a substantially L-shape when viewed from the DR3 direction (third direction). The portion of the second member 220 facing the first member 210 constitutes the second gripping portion 22. A recess 22A is formed on the surface of the second gripping portion 22. The provision of the recess 22A makes it easier to attach to a member having a curved surface. A bolt member 230 is inserted through the portion of the second member 220 that extends in the DR1 direction. However, the portion of the second member 220 that constitutes the second gripping portion 22 and the portion that extends in the DR1 direction may be configured as separate members.

[0027] A rib 221 is formed on the rear end surface of the second member (Figure 7), projecting from the bottom surface in the DR1 direction (first direction). The rib 221 is formed in a grid pattern so as to extend in the DR2 and DR3 directions when viewed from the DR1 direction. A rib 222 is formed on the upper surface of the second member (Figure 4), projecting from the bottom surface in the DR2 direction (second direction). The rib 222 is formed in a grid pattern so as to extend in the DR1 and DR3 directions when viewed from the DR2 direction. However, the form of the ribs 221 and 222 is not limited to these. By providing the ribs 221 and 222, the weight of the second member 220 can be reduced while ensuring the strength of the second gripping portion 22.

[0028] The bolt member 230 is inserted through a nut 212 attached to the first member 210. By rotating the operating part 23A provided on the front end side of the bolt member 230, the first member 210 moves in the DR1 direction. The mounting member 240 constitutes the mounting part 24. The mounting member 240 is screwed onto the second member 220. However, the mounting member 240 may be formed integrally with the second member 220. A retaining nut 250 is provided at the tip of the bolt member 230.

[0029] According to the fixing device 20 of this embodiment, the bolt member 230 can be rotated to slide the first member 210 in the DR1 direction. This allows the opening width of the first gripping portion 21 and the second gripping portion 22 to be changed by a simple mechanism or simple operation, and a construction sign can be clamped between the first gripping portion 21 and the second gripping portion 22.

[0030] Furthermore, since the construction sign can be clamped by the first member 210 and the second member 220, which do not rotate around the DR1 direction, the fixing device 20 can be stably attached to the construction sign compared to a structure in which a member that rotates around the axial direction makes direct contact. In addition, unintended damage to the surface of the construction sign can be suppressed, and the progression of deterioration of the construction sign can be suppressed.

[0031] Furthermore, by positioning the operating portion 23A of the bolt member 230 on the front side of the fastener 20, the fastener 20 can be installed from the front side of the construction sign, thus enabling the construction of a fastener 20 with high installation efficiency.

[0032] Furthermore, by using a resin material for the fastener 20, the degree of freedom in shape is greater and processing is easier compared to fasteners made of metal plates. As a result, it becomes easier to illuminate the entire construction sign with the lighting device 10 without increasing the number of parts, improving the overall visibility of the sign.

[0033] Furthermore, by making the lighting device 10 and the fixing device 20 detachable, the fixing device 20 can be attached to the construction sign first. Therefore, damage to the lighting device 10 due to unintended drops during the installation of the fixing device 20 to the construction sign can be suppressed. In addition, the workability of installing the fixing device 20 to the construction sign is also improved.

[0034] Furthermore, by appropriately adjusting the structure of the base 11 of the lighting device 10 and the mounting portion 24 of the fixing device 20, it is possible to freely change the mounting angle of the lighting device relative to the fixing device 20. For example, in the base 11 and mounting portion 24 illustrated in Figures 1 to 7, fitting is possible in two directions, rotated 90 degrees around the DR2 direction. Therefore, the degree of freedom in the mounting angle of the lighting device 10 relative to the construction sign is improved.

[0035] While embodiments of the present technology have been described above, the embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present technology is defined by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included. [Explanation of Symbols]
