Description

  The present invention relates to a brace fitting for a signal lamp used for attaching a signal lamp (generally, for pedestrians) to a brace provided on a support column.

  A fixing block fixed to a brace provided on a support column, a separation block fixed to a signal lamp, a coil spring connecting both of them, a case surrounding the coil spring, and a lock provided at a fitting portion of the separation block of the case There is a structure composed of a mechanism (for example, Patent Document 1).

  In this conventional structure, when the vehicle collides with the support, the external force acts on the lock mechanism, the separation block separates from the fixed block, the external force acting on the signal lamp is released, and the displacement of the signal lamp is reduced by the elasticity of the coil spring. It is possible to obtain a support device for a signal lamp with no blind spot angle, which can absorb external force acting from all directions by absorbing by deformation.

JP 2003-109186 A

  In the conventional example, the lock mechanism in the normal state acts to maintain the normal position of the signal lamp. However, the signal lamp is suspended by a coil spring due to an external force caused by a vehicle collision or the like, and functions as a lamp. In addition, it is necessary to return the lock mechanism to its original state in order for the signal lamp to work properly, and in any case, unless the lock mechanism is returned to its original state, it will affect the traffic of the vehicle and work will also be required to return it. It is complicated.

  The present invention deals with an external force applied to a signal lamp from any direction that acts due to a vehicle collision or the like, absorbs this, and becomes a cushion material to prevent damage to the signal lamp as much as possible. It was created for the purpose of providing a support device.

  An opening that communicates the inside and outside of the metal base frame is formed on the bottom surface of the hollow cylindrical metal base frame that is detachably suspended from the brace provided on the support column, and is arranged in the metal base frame through the opening. A hooking piece that is hooked to the edge of the opening is provided at the upper end of the connection frame that is attached to the signal lamp, and the hook base piece is opposed to the hooking piece. The configuration is such that a coil spring interposed between them is pressed against the component material. In addition, by adding a point provided with a long hole that engages with the L-shaped tip of the latching piece on both sides of the opening on the lower surface of the metal base frame in this configuration, the signal lamp can be suspended stably in a normal state. The installation state can be obtained.

  According to the present invention, the external force due to the collision of the vehicle is applied to the signal lamp through the connection frame through the coil spring regardless of the direction of the collision, and therefore, the durability that does not select the direction of the collision. A simple signal lamp support device can be obtained.

  In the first and second embodiments of the present invention, the mounting brackets A and A ′ for signal lamp armatures are assembled by attaching substantially rectangular cylindrical metal base frames 1 and 1 ′ and connecting frames 2 and 2 ′. The fastening base 3 is placed on the upper side of the tip of the arm metal a projecting from the support p, and the bracket base frames 1 and 1 'are arranged on the lower side of the arm metal a. A fixing bolt 5 that protrudes from the cover plate 4 (the cover plate 4 is fastened to the flanges 1a and 1'a of the metal base frames 1 and 1 'with a tightening nut 6A) is inserted, and the bolt 5 that protrudes from the tightening rod 3 is inserted. The base frame 1, 1 'is attached to the end of the arm bracket a by screwing and tightening the fastening nut 6 to the tip, and the connecting frames 2, 2' assembled to the metal base frame 1, 1 'are attached. The mounting bolt 7 installed on the signal lamp S is attached to the signal lamp S and is interposed between the signal lamp S and the brace a.

  The metal base frame 1, 1 ′ is provided with an opening 8 on the lower surface thereof for communicating the inside of the base frame 1, 1 ′ with the outside, and is stored inside the base frame 1, 1 ′ through the opening 8. At the upper ends of the connecting frames 2, 2 ′, L-shaped hooking piece 10 that hooks on the receiving piece 9 that forms the edge of the opening 8 is provided on all sides. The latching piece 10 is interposed between the latching piece 10 and the cover plate 4 of the base frame 1, 1 ′ by the bias of the coil spring 11 housed in the base frame 1, 1 ′. The connection frames 2 and 2 ′, which are pressed in the direction of the receiving piece 9 and provided with the hanging piece 10, maintain a stable suspended state.

  The connecting frames 2 and 2 ′ are provided with hook portions 10 provided at the lower end of the cylindrical assembly cylinder 12 provided at the upper end four sides, and the lower end portion formed in an expanded shape. 13, and the fastening ring 14 is engaged with the outside of the assembly cylinder 12 and assembled so as to be locked to the flange piece 13. Then, the connection frames 2 and 2 ′ are installed and erected on the signal lamp S by passing the mounting bolt 7 through the fastening ring 14 and screwing a nut 15 at the tip thereof.

  The signal lamp S engages the coil spring 11 from the upper surface opening side of the base frames 1, 1 ′ inside the metal base frames 1, 1 ′ in which the connection frames 2, 2 ′ are combined. , 1 'upper end flange 1a and the cover plate 4 superposed on the flange 1a are fastened with a fastening bolt 5 and a tightening nut 6A screwed to the cover bolt 4, a coil spring 11, and a metal base frame 1, 1 'and connecting frames 2, 2' are assembled to each other and attached to the brace a of the support p. That is, the arm bracket a is configured to engage between the pair of fastening bolts 5 and 5 which are assembled in a projecting manner on the substrate 4 (metal base frames 1 and 1 ') of the mounting brackets A and A'. And tighten the fastening nut 3 between the fastening bolts 5 and 5 (so that the fastening bolt tip is inserted), and screw the fastening nut 6 onto the tip of the bolt 5 protruding from the fastening rod 3 and tighten. The bracket base frame 1, 1 'side is attached to the arm bracket a by the above (in addition, the fastening bolt 5 of the first embodiment uses a T-bolt, and the second embodiment uses a round head bolt. There is no inconvenience even if another head type is used, although the second embodiment uses the locking nut 6B, it goes without saying that this should also be used in the first embodiment).

  The connection frames 2 and 2 ′ are connected to the fixing bolt 14 projecting from the signal lamp S and the fastening ring 14 is engaged, and a nut 15 is screwed and tightened to the tip of the bolt 7 protruding from the ring 14. The signal lamp S is hung on the arm metal a via the arm metal fittings A and A ′.

  When the signal lamp S is in the suspended state, if, for example, a vehicle hits the support column p and an external force is applied to the support column p, the external force is connected through the metal base frames 1 and 1 'fixed to the brace a. Although the coil spring 11 is interposed between the base frames 1 and 1 ′ and the connection frames 2 and 2 ′, the signal lamp is deformed by the coil spring 11. The external force transmitted to the vessel S will be alleviated.

  The mounting brackets A and A ′ of the first embodiment and the second embodiment (each member is press-molded without using welding means, so a relatively inexpensive product can be provided) The remaining points are substantially the same except that the structures of the metal base frames 1 and 1 'constituting the mounting metal parts A and A' are different, and this difference will be described below.
