Description

  The present invention relates to a mounting bracket for a pedestrian signal lamp used for mounting and supporting a pedestrian signal lamp on a brace provided on a support column.

  In general, a signal lamp for a pedestrian is used by placing a signal lamp column on a road and supporting it on upper and lower arm brackets provided on the column (Patent Document 1).

JP 2003-217075 A

  Although the conventional example adopts a configuration in which the signal lamp is supported by the upper and lower arm brackets, it is durable. However, since the upper and lower sides of the lamp apparatus are attached to the upper and lower arm brackets, the number of mounting parts is inevitably required. Therefore, the mounting work becomes complicated due to the combination of the parts, so that a mounting bracket with good workability is desired.

  The present invention has been devised to address the demand for cost reduction and to provide a mounting bracket for a pedestrian signal lamp that can be easily attached to a brace provided on a support column and is easy to use.

Engage the armrests provided on the struts with the laterally recessed edges and make them face each other, and surround the pair of clamping pieces assembled with each other with the through bolts through which the arms are inserted, and the cable outlet provided on the lamp It is equipped with an inner connection tube and an outer connection tube with the upper end of the opening located at a height above the inner connection tube. A vertical protrusion formed in a semicircular cross-section of the clamping piece, which engages with a circumferential groove provided at the upper part of the connecting cylinder and supports the outer connecting cylinder, and engages with the outer connecting cylinder. Insertion holes for fastening bolts for fastening the clamping pieces to each other are provided on both sides of each clamping piece provided at the insertion edge, and one end of the dressing hose through which the cable passes through the inner connection cylinder. mounting further, on the lower surface of the flange portion of said outer connecting tube, of the connecting tube The circumferential edge provided with a groove which communicates, is taken as the configuration.

  According to the present invention, since the pedestrian signal lamp is attached to and supported by the brace of the support column only at the upper side, the signal lamp can be easily attached to the brace and by loosening the tightening bolt. The direction of the vessel can be easily changed, and a convenient mounting bracket can be provided. And even if there is a cable outlet on the upper surface of the lamp, rainwater does not enter the lamp through the outlet, and the cable outlet is located on the upper surface of the lamp. A mounting bracket that can be performed efficiently can be provided.

Partially missing front view. The top view of FIG. Sectional drawing of FIG. The front view which shows the relationship between a mounting bracket and a brace.

  The drawing shows an embodiment of a mounting fixture for a pedestrian signal lamp according to the present invention. The mounting bracket A mounts a vertical rectangular box-shaped signal lamp S on an upper wall plate 102 provided with a lead-out port 101 of a cable 109. The signal lamp device S is suspended from a brace 103 provided on the support column 107 via the mounting bracket A.

  The mounting bracket A has a pair of sandwiching pieces 1 and 1 having the same diameter as opposed to each other via the outer connection tube 2 standing on the upper surface of the arm metal 103 and the lamp S and the inner connection tube 3 inside thereof. A through bolt 4 passing through the arm metal 103 in the radial direction, a pair of tightening bolts 5 and 5 disposed on both sides of the outer connecting tube 2, and a nut 4a screwed to these. , 5a are fastened to each other through the arm metal 103, and the lamp S is attached to the arm metal 103 at the upper part thereof.

  The sandwiching piece 1 is obtained by press-molding a steel plate, and is provided with a semi-circular transverse recess edge 6 on the upper side and a vertical semi-circular recess edge 7 on the lower side. The recessed edge 7 is positioned at the center of the laterally recessed edge 6. The laterally recessed edge 6 is associated with the middle portion of the arm metal 103, and the longitudinally recessed edge 7 is associated with the outer connecting cylinder 2. Try to match. The upper piece 6A constituting the lateral recess edge 6 is provided with an insertion hole 8 of the through-bolt 4 positioned at the center in the longitudinal direction, and a convex portion 9a and a concave portion 9b at the upper end edge (tip edge). While providing unevenness with equal widths to each other, the lower piece 7A constituting the vertical recess edge 7 is provided with a latching ridge 11 that engages with the circumferential groove 10 provided in the outer connecting tube 2, Through holes 12 through which the tightening bolts 5 are inserted are formed in side portions 7A ′ and 7A ′ made of a flange-like flat plate of the lower piece 7A on both sides of the latching protrusion 11 (concave edge 7).

The inner connecting tube 3, the outer connecting cylinder 2 tubular to the open top was more arranged open top to a high place of the inner connecting tube 3 is a cylindrical steel which was obtained by press working, opening the upper and lower ends a cylindrical portion 3a, 2a and the cylindrical portion 3a, the flange portion 3b is protruded to the lower end of the 2a, made in a 2b, a flange portion 3b, the mounting bolts 13 provided to match with each other at equal intervals in 2b Through holes 14 and 15 (three in each embodiment) are provided, and on the lower surface of the flange portion 2b of the outer connecting tube 2, a rib 16 is provided to form a groove 16 that communicates the cylindrical portion 2a with the outside world. Rainwater that has entered the interior of 2a can be discharged to the outside.

  Then, the outer connecting cylinder 2, the inner connecting cylinder 3 and the packing 17 are combined so that the mounting bolts 13 are inserted into the through holes 14 and 15 provided in the flange portions 2b and 3b and the through holes provided in the packing 17, The tip of each mounting bolt 13 is inserted through a through hole 18 provided in the reinforcing wall plate 102 that overlaps the through hole 18 provided in the upper wall plate 102 of the lamp S and the back surface of the upper wall plate 102, The inner and outer connecting cylinders 2 and 3 are assembled to the signal lamp S by screwing and tightening a mounting nut 13a to the tip of the bolt 13 protruding from the plate 19, and project on the lamp S so as to surround the outlet 101. Is done.

  Then, a through bolt 4 is inserted into the pair of clamping pieces 1 and 1 and the brace 103 which are opposed to each other with the arm metal 103 interposed therebetween, and a nut is attached to the tip of the bolt 4 protruding from the one clamping piece 1. 4a is loosely screwed together so that the pair of clamping pieces 1 and 1 are opposed to the arm metal 103 and assembled to the signal lamp S side between the opposing vertical concave edges 7 and 7 of the clamping pieces 1 and 1. The attached outer connecting cylinder 2 is inserted from the lower side of the clamping piece 1, and the outer connecting cylinder 2, that is, until the circumferential groove 10 provided in the connecting cylinder 2 engages with the latching ridge 11 provided on the longitudinal recess 7. When the signal lamp S assembled with the connecting tube 2 is lifted and engaged, the nut 4a is tightened, while a bolt 5 that is appropriately passed between the through holes 12 and a tightening nut 5a that is screwed into the bolt 5 When the lower piece 7A of the clamping piece 1 tightens the side portions 7A ′ and 7A ′ The signal lamp S is suspended from a brace 103 provided on the support column.

  It should be noted that one end of the dressing hose 23 is fitted and attached to the inner connecting cylinder 3 from the outside at an appropriate time during the work (although not necessarily in the order of the work). The hose 23 prevents rainwater from contacting the cable led out from the lamp S through the hose 23 as much as possible, and prevents rainwater from entering the lamp S through the outlet 101 formed in the lamp S. With the goal.

  As described above, the groove 16 provided in the flange portion 2b of the outer connecting tube 2 is expected to have this rain effect, and rainwater that has fallen between the outer connecting tube 2 and the inner connecting tube 3 or the dressing hose 23 is It is discharged to the outside of the mounting bracket A through this groove 16 located on the flange portion 3b of the inner connecting cylinder 3.
