Description

  The present invention relates to a fixing bracket, and more particularly, to a fixing bracket used for fixing a traffic-related sensing device such as an ultrasonic sensor, an image sensor, and an optical beacon to a column.

  Traffic-related sensing devices such as ultrasonic sensors, image sensors, and optical beacons are generally installed on existing traffic lights and utility poles. As a metal fitting used at the time of attachment, for example, there is known a type of metal fitting that is fixed to a columnar support arm with a bolt using a pair of metal holding bands having a semicircular outer shape (Patent Document 1). reference). In this type of metal clamping band, a plurality of types of mounting brackets are prepared in advance as standard sizes corresponding to a plurality of arm diameters to be attached.

JP 2008-20985 A

  By the way, when a sensor or the like is installed on a support arm or the like having an arm diameter other than the standard size, there are many cases where several types of mounting brackets are prepared depending on each arm diameter. These mounting brackets are selected by the factory in accordance with the drawing number instructions from the design department. However, since there are multiple types, there is a possibility of human error such as an instruction error or a manufacturing / shipping error. Also, in order to shorten the delivery time from order receipt to shipment, it has been desired that the factory can handle the shipment without specific instructions from the design department.

  This invention is made | formed in view of such a condition, Comprising: The technique which solves the said subject is provided.

The present invention is a fixing bracket for attaching a sensing device for traffic to a support arm, an angle member for attaching the sensing device, a metal band, and fastening for winding and fixing the band around the support arm And a plurality of openings formed along the winding direction of the band and used for fixing by the fastening portion, and the opening. , when fixed wound on said support arm, Ru includes an anti-rotation shape to prevent rotation.

  ADVANTAGE OF THE INVENTION According to this invention, in the fixing metal fitting which attaches the sensing apparatus for traffic to a support arm, the technique which can be attached corresponding to the diameter of a support arm flexibly can be provided.

It is the side view which showed the state by which the ultrasonic sensor based on this embodiment was attached to the support arm using the sensor attachment metal fitting. It is the top view which showed the state by which the ultrasonic sensor based on this embodiment was attached to the support arm using the sensor attachment metal fitting. It is a partial side view of the band based on this embodiment. It is the figure which paid its attention to the opening of the band based on the modification of this embodiment. It is a partial side view of the band based on the modification of this embodiment.

  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings.

  FIG. 1 is a side view showing a state in which the ultrasonic sensor 60 is attached to the support arm 90 using the sensor attachment fitting 10. FIG. 2 shows a top view of the state. FIG. 3 shows a part of the side shape of the band 20.

  The support arm 90 has, for example, a structure extending in the horizontal direction, and a traffic device such as a signal lamp is installed. The ultrasonic sensor 60 is installed on the support arm 90 using the sensor mounting bracket 10.

  The sensor mounting bracket 10 includes a band 20, a band angle connecting bracket 40, and a sensor mounting angle 50.

  The sensor mounting angle 50 is formed of an inverted L-shaped steel material in a side view. Specifically, the sensor mounting angle 50 includes a vertical part 51 that is attached to the band angle coupling bracket 40 and extends upward, an upper side part 52 that extends forward from the upper end of the vertical part 51, and a lower part at the tip of the upper side part 52. And a hanging part 53 extending in the direction. An ultrasonic sensor 60 is attached to the lower end portion of the hanging portion 53 so as to face downward.

  The band 20 is mainly formed of steel and is used as a means for attaching to the support arm 90. Specifically, the band 20 includes a band-shaped band main body 21 and a band fastening portion 30 attached to one end thereof.

  The band main body 21 includes a plurality of openings 22 at a predetermined pitch along the winding direction. Here, the opening 22 is rectangular. One end side of the band body 21 is a stopper mounting portion 25, and a band fastening portion 30 is provided.

  The band fastening portion 30 includes a hook 31 and a stopper 32 having a substantially inverted U shape in side view as shown in FIG. A hook 31 is attached to the stopper 32 so as to be inserted. The front end of the hook 31 is a locking claw 33, which is locked to the opening 22 of the band 20. Specifically, a locking portion 23 is formed between the adjacent openings 22 so as to protrude slightly upward.

  The band 20 is wound around the support arm 90, and the stopper 32 is locked to the locking portion 23 (opening 22). And the band main body 21 is diameter-reduced by inserting and fastening the nut 35 to the volt | bolt part 34 formed in the other side of the latching claw 33. FIG.

  The band angle connecting bracket 40 has a substantially rectangular cylindrical shape, and connects the sensor mounting angle 50 and the band 20. Here, the left-right direction is an opening, and the sensor attachment angle 50 is attached to the front surface. In the back surface, the upper and lower central portions are recessed in a valley shape (triangular shape) on the inner side, and this portion is pressed against the support arm 90.

  A band insertion opening 45 is formed in the upper surface 43 and the lower surface 44, and the band main body 21 of the band 20 can be inserted. That is, the band 20 can be securely fixed to the support arm 90 by reducing the diameter of the band main body 21 after the band 20 is inserted into the band insertion opening 45 of the band angle connecting fitting 40.

  In this way, by fixing the ultrasonic sensor 60 to the support arm 90 using the band 20, it is possible to flexibly cope with a plurality of arm diameters with a single type of sensor mounting bracket 10. In particular, when the ultrasonic sensor 60 is fixed to the support arm 90 having a special diameter other than the standard size, there is no need to design and manufacture it separately.

  In particular, the support arm 90 may be different depending on a local public organization to be managed, an existing old facility, or the like, and may not be a standard size. However, according to this embodiment, since one type of sensor mounting bracket 10 can cope with a plurality of types of arm diameters, it is possible to prevent human errors, reduce management man-hours, and shorten delivery times.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications are possible for the combination of each of those components, and such modifications are also within the scope of the present invention.

  FIG. 4 is a partial plan view showing a band 20a of a modification, and focuses on the band main body 21. FIG. In the region 21a on the stopper mounting portion 25 side. Openings 22 having a length L11 are formed at a pitch L12. On the other hand, an opening 22 having a length L13 shorter than the opening 22 of the region 21a on the stopper mounting portion 25 side is formed in the region 21b on the opposite side to the stopper mounting portion 25 side, that is, on the end portion side of the band main body 21. The pitch L12 is the same. When the arm diameter is small, the opening 22 in the region 21a on the stopper mounting portion 25 side is used for band fastening. In this case, the curvature radius of the band main body 21 becomes small and the bending becomes large. Therefore, the opening 22 is formed to be large so that the band main body 21 is easily bent.

  FIG. 5 is a partial side view of the band 20b. An anti-rotation claw 26 is provided on the band back surface 21 a of the band body 21. When the band main body 21 is fastened, the rotation preventing claw 26 bites into the support arm 90 and rotation is prevented.
