Description

[Technical Field]

[0001] The present disclosure relates to a mounting bracket for a lighting fixture with a pan head. [Background technology]

[0002] Lane restrictions are sometimes implemented due to road construction on expressways, motorways, general roads, etc. Lane restrictions are implemented, for example, by placing flares in the lanes where vehicles are prohibited from traveling or signs encouraging drivers to change lanes into the adjacent lanes to notify drivers of the restrictions. Summary of the Invention [Problem to be solved by the invention]

[0003] Instead of placing objects such as flares or signs in prohibited lanes, it is possible to use arrow projection lights to project arrows onto the road surface to encourage drivers to change lanes.In addition to such arrow projectors, there has been a demand for lighting fixtures that can be installed quickly and easily in order to smoothly carry out road construction work at night within a limited time.

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The dimensions, materials, shapes, and relative positions of the components described in the present embodiments are not intended to limit the technical scope of the present disclosure unless otherwise specified.

[0009] Fig. 1A is a plan view of a mounting fixture 1 for a lighting fixture according to an embodiment, and Fig. 1B is a front view of the mounting fixture 1. Fig. 2A is a front view of a second member constituting the mounting fixture 1, Fig. 2B is a left side view of the second member, and Fig. 2C is a rear view of the second member. Fig. 3 is a diagram showing a lighting fixture 40 with a pan head 30 attached to a cylinder 50.

[0010] 1A and 1B, the mounting fixture 1 is made of a main body 10, which is a first member, and a mounting portion 20, which is a second member. The main body 10 and the mounting portion 20 are made of metal and are formed by metal processing. However, materials other than metal (such as resin) can be used to form the mounting fixture 1 as long as the necessary strength and functionality can be obtained.

[0011] The main body 10 includes a clamp 11, a base member 12 to which the attachment portion 20 is attached so as to be insertable and detachable, and a connecting portion 13 that connects the clamp 11 and the base member 12 together.

[0012] The clamp 11 is used to secure the main body 10 to a pillar-like object erected on the side of a road or on the road. Fig. 3 shows a cylinder 50 as an example of the pillar-like object. The clamp 11 has arc-shaped members 111 and 112 formed to fit the outer diameter of the cylinder 50, and the clamp can be opened and closed by rotating the arc-shaped member 112 about an axis 113. With the inner surfaces of the arc-shaped members 111 and 112 in contact with the circumferential surface of the cylinder 50, the ends of the arc-shaped members 111 and 112 are tightened with screws 18, thereby firmly securing the main body 10 to the cylinder 50.

[0013] The clamp 11 is an example of a fixing device. However, fixing means (fixing devices) other than the clamp 11 may be applied as long as the mounting fixture 1 can be fixed to a columnar object. Furthermore, the cross-sectional shape of the columnar object may be other than a circle (e.g., an oval, a triangle, a polygon with more sides than a square, etc.), and the shape of the clamp 11 is formed to match the cross-sectional shape of the columnar object.

[0014] The connecting portion 13 has a cylindrical shape that protrudes from the outer surface of the arc-shaped member 112. When the main body 10 is fixed to the cylinder 50 by the clamp 11, the connecting portion 13 extends in a direction perpendicular to the central axis of the arc-shaped members 111 and 112 (the central axis of the cylinder 50). The tip of the connecting portion 13 is open, the inside is hollow, and a screw hole is formed on the inner peripheral surface.

[0015] The base member 12 is formed in a substantially rectangular shape when viewed from the front, with a flat portion 121 formed in its central portion. The left and right portions continuing from the flat portion 121 are bent inward at the same angle to form ears 122, 123 as support portions. In this way, the base member 12 has a bilaterally symmetrical structure with respect to its vertical center line. However, the bending angle of each ear 122, 123 relative to the flat portion 121 can be set appropriately. Furthermore, the ears 122 and 123 do not necessarily have to be bilaterally symmetrical. In other words, the angles formed by the flat portion 121 and the ears 122, 123 may be different on the left and right.

[0016] A bolt hole 16 is formed in the flat portion 121, and a bolt 14 with a washer attached is passed through the bolt hole 16 and the outer peripheral surface of the bolt 14 is screwed onto the inner peripheral surface of the connecting portion 13, thereby fixing the base member 12 to the tip of the connecting portion 13. However, the base member 12 and the connecting portion 13 may be integrally formed by welding or the like.

[0017] The ears 122 and 123 each have an outer surface on which an insertion portion 15 (151, 152) of the mounting portion 20 is formed. Each of the insertion portions 151, 152 is open in the vertical direction, with the upper opening serving as an insertion port.

[0018] The mounting portion 20 is integrally formed with a base piece 21, an insertion piece 23, and a connection portion 22 that connects the base piece 21 and the insertion piece 23. The upper surface of the base piece 21 is a flat surface that serves as the mounting surface for the pan head 30 of the lighting fixture. The insertion piece 23 has dimensions that allow it to be inserted into the insertion receiving portion 15 (each of the insertion receiving portions 151 and 152), and the upper end of the insertion piece 23 and the upper end of the base piece 21 are connected by the connection portion 22. The connection portion 22 extends in a direction perpendicular to the insertion piece 23. The mounting portion 20 can be formed, for example, by bending a metal plate, but it can also be formed by casting or the like.

[0019] As shown in FIG. 2B, the insertion piece 23 and the base piece 21 are formed to have a predetermined angle (for example, 45°). In other words, when the mounting portion 20 is attached to the main body 10, the base piece 21 is formed to have a predetermined depression angle (for example, 35° to 55°, preferably 45°). The mounting portion 20 is formed as shown. However, the predetermined angle (depression angle) can be set appropriately and may be greater or less than 45°. The base piece 21 is formed with a through hole 24 for fixing the lighting fixture 40.

[0020] When the main body 10 is fixed to the column 50, the lower end of the insertion piece 23 is inserted into the insertion receiving portion 15 (151 or 152), and the lower surface of the connection portion 22 abuts against the upper part of the insertion receiving portion 15 and stops. In this way, the connection portion 22 regulates the insertion depth of the insertion piece 23. In this inserted state, the insertion piece 23 is supported by the base member 12 in an upright state along the vertical axis, and the mounting surface of the base piece 21 is positioned at a predetermined angle range (for example, 45° in the range of 35° to 55°) with respect to the vertical axis. Note that the vertical dimension of the insertion receiving portion 15 may be formed to be longer than the vertical dimension of the insertion piece 23, in which case the lower end of the insertion receiving portion 15 may be closed.

[0021] In addition, holes are formed in the flat portion 121 for connecting one of the carabiners attached to both ends of a rope having a predetermined length. The other carabiner is attached at a high position, and when the fixed state of the main body 10 to the column 50 is released, the mounting tool 1 (the lighting fixture 40 attached to it) is suspended by the rope, making it possible to avoid collision with the ground.

[0022] As shown in Figure 3, a pan head 30 is attached to the lower end of lighting fixture 40 (lighting fixture with a pan head). With the lower end surface of the base of pan head 30 in close contact with the upper surface (mounting surface) of base piece 21 of mounting part 20, pan head 30 is bolted to base piece 21 using through holes 24. This fixes mounting part 20 to pan head 30.

[0023] Insertion piece 23, which is integrated with pan head 30, can be inserted into one of insertion receiving portions 151 and 152 of main body 10, which is fixed to column 50. When insertion piece 23 is inserted into insertion receiving portion 151, lighting fixture 40 can be positioned facing right as one faces the road. Conversely, when insertion piece 23 is inserted into insertion receiving portion 152, lighting fixture 40 can be positioned facing left as one faces the road. The orientation of lighting fixture 40 can be easily changed by selecting insertion receiving portion 15.

[0024] The lighting fixture 40 has a light 43 that emits light. The light 43 may emit illumination light or may project predetermined symbols (figures, symbols, letters, etc.) onto the road. The symbols are used, for example, to encourage drivers to change lanes or to prohibit drivers from entering a predetermined lane. However, the symbols can be set or changed as appropriate depending on the purpose of the light projection.

[0025] The lighting fixture 40 and the pan head 30 are connected via a ball joint (universal joint) 33, and the lighting fixture 40 can be tilted in any direction around the axis of the ball joint 33. The lighting fixture 40 has a handle 41 and a lever 42. When the lever 42 is not gripped, the position of the lighting fixture 40 relative to the pan head 30 (the relative angle between the lighting fixture 40 and the pan head 30) is maintained fixed. In contrast, when the lever 42 is gripped, the position (fixed state) of the lighting fixture 40 relative to the pan head 30 is released. In this released state, the lighting fixture is tilted in the desired direction using the handle, and the lever 42 is released, whereby the position of the lighting fixture 40 relative to the pan head 30 is fixed. By adjusting the position in this way, it is possible to illuminate a desired lane with illumination light or project a desired symbol onto a desired lane.

[0026] The mounting fixture 1 in this embodiment is used to mount a lighting fixture 40 having a pan head 30 on a columnar object (for example, a cylinder 50). The mounting fixture 1 includes a main body 10 (first member) and a mounting part 20 (second member) that has a fixing part (base piece 21) for the pan head 30 and is attached to the main body 10 so as to be insertable and detachable. The main body 10 further includes a support part (base member 12) for the mounting part 20, a fixture (clamp 11) that fixes the main body 10 to the cylinder 50, and a fixing device (clamp 11) that fixes the base member 12 and the clamp. and a connecting portion 13 that connects the pump 11 to the connecting portion 13.

[0027] When using the fixture 1, the mounting part 20 is fixed in advance to the pan head 30 of the lighting fixture 40, and the main body 10 is fixed in advance at a predetermined height to the cylinder 50. Depending on the range of illumination or symbol projection, one or more lighting fixtures 40 with cylinder 50, fixture 1, and pan head 30 are prepared.

[0028] Then, the insertion piece 23 of the mounting part 20 attached to the lighting fixture 40 is inserted into the insertion receiving part 15 of the main body 10 fixed to the cylinder 50, thereby easily fixing and positioning the lighting fixture 40 on the cylinder 50. Furthermore, the lighting fixture 40 can be easily removed from the cylinder 50 by pulling out the insertion piece 23 from the insertion receiving part 15. Therefore, the lighting fixture 40 can be easily positioned in a short time, and can illuminate a desired part of the road surface or project a symbol onto a desired part to encourage a lane change.

[0029] Furthermore, main body 10 has two insertion receiving portions 151 and 152, and the orientation of lighting device 40 can be easily changed by inserting insertion piece 23 into either of these. However, it is not essential that main body 10 (first member) has two or more insertion receiving portions 15, and even if it has a single insertion receiving portion 15, it can still have the effect of allowing the lighting device to be easily attached and detached in a short period of time.

[0030] The support portion (ears 122, 123 of the main body) according to the embodiment may include a receiving portion (151, 152) into which a part of the first member (main body 10) is inserted. The receiving portion (151, 152) may have an insertion port facing upward. However, as long as the lighting device 40 can be properly fixed, the insertion direction of the insertion piece into the insertion portion may be configured to be the left-right direction.

[0031] In the embodiment, the second member (mounting portion 20) can include a base piece 21 having a flat surface (mounting surface) to which the pan head 30 is fixed, an insertion piece 23 to be inserted into the insertion receiving portion 15, and a connection portion 22 that connects the base piece 21 and the insertion piece 23 and regulates the insertion depth of the insertion piece 23 into the insertion receiving portion 15. Furthermore, the above-mentioned flat surface can be configured to extend downward when the insertion piece 23 is inserted into the insertion receiving portion 15. The depression angle of the flat surface when the insertion piece 23 is inserted into the insertion receiving portion 15 can be configured to be 35° to 55°, preferably 45°.

[0032] Furthermore, the number of support parts provided on the main body 10 in the embodiment may be one, but a configuration having two or more inserted parts 15 provided at different angles may also be employed. Also, a configuration in which two inserted parts 151, 152 are provided symmetrically with respect to the center line in the vertical direction of the main body 10 may also be employed. The configuration of the embodiment may be modified as appropriate within the scope that the object of the present invention can be achieved. [Explanation of symbols]
