Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket for a pedestrian signal light. 2. Description of the Related Art A pedestrian signal light is horizontally provided (projected) on a pillar.
As a conventional structure to be attached to the arm, a connecting piece is formed at the tip of the arm by expanding and a threaded rod protruding from the signal lamp is penetrated through an annular connecting metal fitting to the connecting piece. There is a structure in which a nut is screwed and fastened to the lever (Japanese Utility Model Publication No. 55-6804). [0003] In short, the prior art employs a configuration in which the pedestrian signal light is mounted on the arm using the tip of the arm. The position of the lamp is determined by the length (the amount of protrusion from the support), and the mounting state of the lamp at a distance from the support cannot be obtained in accordance with the situation at the site. Also, the structure itself becomes complicated,
There is a demand for labor-saving mounting work. Means for Solving the Problems A pair of holding pieces fastened to each other by bolts and nuts are engaged with an intermediate portion of an arm bar laterally provided on a support column on an upper portion of each holding piece on the opposite surface side. A vertical concave edge is provided at the lower portion for engaging a mounting tube erected on the lamp, and the vertical concave edge is engaged with a peripheral groove formed on the mounting tube. That is, the ridges are provided. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view showing a mounting of a pedestrian traffic light according to an embodiment of the present invention; FIG. 3 is a partially enlarged longitudinal sectional view, FIG. 3 is a plan view of FIG. 2, and FIG. 4 is a perspective view of a holding piece. The mounting device of the embodiment is mounted on a support (not shown) using a band body not shown, and each of an upper arm 1 and a lower arm 2 is protruded from the support. The mounting bracket A according to the present invention is mounted on the upper part of the pedestrian signal lamp L so that the upper part of the pedestrian signal lamp L is mounted and supported. Although the lower part of the lamp L is attached and supported, the lower part of the lamp L may be supported by using the mounting bracket A instead of the second mounting bracket Aa. In the mounting bracket A, a pair of holding pieces 3 and 3 having the same shape are opposed to each other via a mounting cylinder 4 erected on the upper surface of the upper arm 1 and the lighting device L. A pair of bolt rods 5a, 5b and nuts 6a, 6b screwed to each other are tightened together, and the upper side of the lamp L is armed (upper arm 1).
It was used by attaching it to The holding piece 3 is obtained by press-forming a steel plate, and has a horizontal recessed edge 7 on the upper side communicating with the center of the horizontal recessed edge 7 (located at the center). Edges 8 are provided on the lower side, and the horizontal recessed edge 7 is engaged with the intermediate portion of the upper arm bar 1, and the vertical recessed edge 8 is engaged with the mounting cylinder 4, thereby forming the horizontal recessed edge 7. The upper piece 7A is provided with a through hole 9 for the first bolt 5a at the center thereof, and a recess 10a at the upper end edge (tip edge).
The protrusions 10b are provided with concavities and convexities each having the same width. On the other hand, the lower piece 8A constituting the vertical recessed edge 8 is provided with a through hole 9a for the second bolt 5b on the upper center side thereof.
A ridge 12 that engages with a circumferential groove 11 formed in the mounting cylinder 4 is provided on a lower side so as to protrude inward of the vertical recessed edge 8. The lower piece 8A constitutes a vertical recessed edge 8 and has a main portion 8A 'having a through hole 9a and a ridge 12, and a side portion formed of a flange-like flat plate on both sides of the main portion 8A'. 8A '
′, The side portion 8A ″ may be omitted if processing or design effects are ignored. Thus, the pair of holding pieces 3, 3 are opposed to each other via the upper arm 1 so that the through hole 9 is aligned with the insertion hole 13 formed in the intermediate portion of the upper arm 1, and the through holes 9, 9
And a nut 6a is screwed into a tip of the first bolt 5a protruding from one of the through holes 9, and a mounting bracket A including a pair of holding pieces 3 is attached to the upper arm metal. 1, the mounting tube 4 provided on the signal lamp L is inserted between the holding pieces 3, 3, and the ridge 12 is arranged at a position corresponding to the circumferential groove 11. , 3 recesses 10a,
The nut 6 is engaged with the projections 10b so as to engage with each other.
a, while the second bolt 5b penetrates the through hole 9b, and the second bolt 5b protrudes from the one through hole 9b.
Of the lamp L by screwing the nut 6b to the tip of
The upper side of is assembled and supported on the upper arm 1 and then
The lower side of the lamp L is assembled and supported on the lower arm 2 using the second mounting bracket Aa, so that the mounting state of the pedestrian signal lamp L using the mounting bracket A according to the present invention can be obtained. . The reason why the pair of holding pieces 3 and 3 are formed as a single one is to reduce costs such as inventory control and the like, and the unevenness 10a and 10b are provided for the lamp L. The purpose of this is to stabilize the mounting state of the column and to determine the positioning for assembling the pair of holding pieces 3. Since the present invention has the configuration as described above,
A pair of holding pieces are opposed to each other to hold the mounting tube provided with the arm arm middle part and the pedestrian lamp, and it is easy to mount by simply tightening each other.After mounting, the nut is loosened to rotate the lamp. Can be converted to a desired direction, and a lamp mounting device with good mounting and ease of use can be provided. Further, since the lamp is mounted in the middle part of the arm, the front end of the arm can be used for mounting equipment such as a speaker, and is practical.
