Abstract

<P>PROBLEM TO BE SOLVED: To provide a coping which stabilizes actuation of the sensor and is excellent in the appearance. <P>SOLUTION: The coping placed on an upper end of a fence comprises a long pressure-sensitive sensor arranged in the center of a base body in the longitudinal direction, and a pair of repulsion devices arranged on both sides of the pressure-sensitive sensor. An upper member is supported by the repulsion devices. When a force is applied to the upper member, the pressure-sensitive sensor outputs a signal, accordingly. Since a stable signal is output irrespective of the position of the load applied to the upper member, setting of sensibility of the sensor is carried out accurately, the sensor is not actuated by the load applied by a dog, a cat, etc., stepping on the coping, and it is actuated surely when a person steps on the coping. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a headboard installed at the upper end of a fence disposed around a house, a store, or the like, and more particularly to a headboard incorporating a sensor capable of detecting the presence of an intruder.

Japanese Utility Model Publication No. 52-71246 Japanese Utility Model Laid-Open Publication No. 52-71246 discloses an upper side cross that constitutes a fence body with an outer frame, and the inner and outer frames are always directed upward by a spring. When a load exceeding a certain level is applied to this outer frame, an alarm switch that operates by pushing down the outer frame against the spring force is housed in the horizontal rail, and these are connected to one span. In addition, a fence is proposed in which an arbitrary number of spans are connected and an electric wire connecting switches of each span is passed through the upper horizontal rail.

  However, in the fence described in Japanese Utility Model Publication No. 52-71246, the position of the microswitch for detecting an intruder and the position of the spring for repelling the outer frame are provided at positions separated in the longitudinal direction of the outer frame. There is a problem that the operation of the microswitch is not stable depending on the position where the intruder touches the outer frame.

  Therefore, the present inventor proposes a coping having a stable sensor operation and a beautiful appearance as a result of intensive studies in view of the conventional drawbacks.

  The headboard of the present invention is a headboard installed at the upper end of the cage, and a long pressure-sensitive sensor is provided in the center of the base in the longitudinal direction, and a pair of elastic devices are provided on both sides of the pressure-sensitive sensor. The upper member is supported by the impact device, and the pressure sensor outputs an appropriate signal when a force is applied to the upper member. Since a stable signal is output regardless of the position, the sensitivity of the sensor can be set accurately.

  As described above, the headboard of the present invention is a headboard installed at the upper end of the ridge, and a long pressure sensor is provided in the center of the base in the longitudinal direction, and a pair of elastic sensors are provided on both sides of the pressure sensor. An emitting device is provided, and an upper member is supported on the impacting device, and when a force is applied to the upper member, the pressure-sensitive sensor appropriately outputs a signal. A stable signal is output regardless of the position of the load applied to the sensor, so the sensitivity of the sensor can be set accurately. Can be operated accurately when

The present invention will be described below with reference to the drawings.
FIG. 1 is a front view of a block cage in which the headboard of the present invention is arranged at the top, and FIG. 2 is a side view. In the figure, a is a block fence, and a cap b is placed on the top.

  3 is a cross-sectional view in the AA direction of the headboard, FIG. 4 is a cross-sectional view in the BB direction, and FIG. 5 is a CC cross-sectional view. In the figure, the headboard is composed of a base 1 and an upper member 2, and a long pressure-sensitive sensor 3 is provided at the center of the base 1 over the entire length in the longitudinal direction. Leaf springs 4 are provided on both sides of the pressure-sensitive sensor 3 to form a resilient device. The upper member 2 is placed on the plate spring 4 and supported by the elastic force of the plate spring 4. Further, a protrusion is provided at an appropriate interval in the center of the upper member 2 to form a sensor presser 5.

  FIG. 6 is a cross-sectional view in the AA direction showing the state when a load is applied to the upper member 2 of the headboard. When the load is applied to the upper member 2, two portions are provided on the inner surface of the upper member 2. The pressed contact portion 21 pushes down the leaf spring 4, and the sensor press 5 provided at the center of the upper member 2 presses the pressure sensor 3.

  The pressure-sensitive sensor 3 is in the form of a cord, and when pressure is applied, a change in electrical resistance is generated, and a load applied to the headboard is detected by the change in resistance.

  As the base 1 and the upper member 2 of the present invention, an aluminum alloy mold material having high rigidity and excellent durability is preferably used. However, the present invention is not limited to this, and a mold material obtained by extruding a synthetic resin or the like is used. Alternatively, it may be produced by bending a metal plate such as a steel plate.

  As the elastic device in the present invention, a metal spring such as the above-described leaf spring is preferably used, but a string spring or the like, or an elastic material such as rubber or soft synthetic resin may be used.
