DETAILED DESCRIPTION OF THE INVENTION
[0024] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0025] 1 shows an anti-theft sensor unit 1 according to the present invention attached to a steering wheel lock 2, illustrating one example of the basic usage of the present invention. If an attempt is made to move or disconnect the steering wheel lock 2 in this state, the sensor 3 will be activated and an alarm will sound. The on / off switching of the sensor 3, the volume of the alarm sound, the vibration sensitivity, etc. can be controlled using a remote control (not shown).
[0026] Fig. 2 is a perspective view of the sensor unit 1 as seen from the side, and Fig. 3 is a plan view as seen from above. In other words, the sensor unit 1 is in a state where the sensor 3 is attached to the anti-theft sensor attachment attachment 4.
[0027] Figures 4 and 5 each show the configuration of sensor unit 1. Figure 4 shows how sensor unit 1 is attached to circular rod-shaped portion 5 of handle lock 2, and Figure 5 shows how sensor unit 1 is attached to oval rod-shaped portion 6 of handle lock 2.
[0028] Sensor 3 is a roughly rectangular vibration sensor with arc-shaped corners that detects vibrations and sounds an alarm. The sensitivity can be adjusted according to the magnitude of the vibration, and it can also be adjusted so that the alarm does not sound if the vibration is not strong enough to pose a risk of theft. The alarm sound can also be adjusted to the required volume. The alarm sound can be set and turned off, and the sensor sensitivity can be adjusted using the remote control.
[0029] The sensor mounting attachment 4 is composed of a table-shaped holder 10 on which the sensor 3 is placed, and a clamp 20 that holds the holder 10 on its upper surface.
[0030] The holder 10 has a plate 11 that is approximately the same size as the bottom surface of the sensor 3. The plate 11 has a mating piece 12 that extends long in the longitudinal direction of the periphery and a mating piece 13 that is short in the lateral direction of the periphery. In the example shown in the figure, there are a total of two mating pieces 12 and a total of four mating pieces 13, but these can be changed as appropriate depending on the shape of the bottom of the sensor 3.
[0031] A concave groove 14 is formed protruding downward in approximately the center of the plate 11, and two holes 15 are drilled in the groove 14 to pass through screws for fastening the clamp 20 and the holder 10.
[0032] The clamp 20 is a component for mounting on a rod-shaped part such as a handlebar lock 2 or a U-shaped lock used on motorcycles and bicycles, and is made up of a pair of convex brackets 21, 22 fastened symmetrically above and below via bolts 23 threaded into both ends, thereby clamping the rod-shaped part. Bolts 23 are preferably hexagon socket bolts from the viewpoint of theft prevention.
[0033] Two screw holes 24 are provided at the top of the upper bracket 21, and ultra-low head screws 25 equipped with spring washers are threaded into the holes 15 in the recessed grooves 14 of the holder 10 to fasten it to the holder 10. The recessed grooves 14 prevent the tops of the ultra-low head screws 25 from contacting the bottom surface of the sensor 3, allowing the sensor 3 to be smoothly placed on the holder 10.
[0034] The inner surfaces 21a, 22a of the brackets 21, 22 are formed in an oval shape, making it possible to clamp rod-shaped parts of various shapes and sizes. For example, as shown in Figures 4, 5, 7, and 8, it is possible to accommodate rod-shaped parts of various shapes and sizes, such as a circular rod-shaped part 5 and an oval rod-shaped part 6.
[0035] In addition, the clamp 20 is formed so that the size of the rod-shaped portion is preferably 20 mm to 34 mm in diameter for the circular rod-shaped portion 5, and up to 44 x 25 mm for the oval rod-shaped portion 6.
[0036] The sensor 3 is held in the holder 10 by fitting its bottom to the fitting pieces 12 and 13. By attaching double-sided tape (not shown) to the bottom of the sensor 3, the sensor 3 and the holder 10 can be firmly attached.
[0037] Figure 1 shows a state in which a sensor unit 1 is attached to a steering lock 2. In this state, if an attempt is made to cut the steering wheel 2 and vibrations are applied, an alarm sound from the sensor 3 will sound, preventing theft of the car. [Industrial Applicability]
[0038] The anti-theft sensor unit and anti-theft sensor mounting attachment of this invention were primarily developed for use with automobile handlebar locks, but can also be attached to U-shaped locks and frames of motorcycles and bicycles, and can also be used on rod-shaped parts used on motorcycles and bicycles.
[0039] The theft prevention sensor unit and the theft prevention sensor attachment according to the present invention have been described in accordance with the embodiments. However, the present invention is not limited to these, and within the scope described in the utility model registration claims, the form can be appropriately changed and implemented.
