Description

Technical Field

[0001] The present invention relates to a vehicle stopper.

Background Art

[0002] Conventionally, at the entrances of parking lots, parks, etc., vehicle stoppers are installed to prevent the intrusion of vehicles and the like. A general vehicle stopper is formed by digging a cylindrical hole in the ground using an excavator or the like, burying a pipe, and vertically installing a support column so that it can be inserted and removed into the pipe. Then, when preventing entry, the support column is pulled out upward, and when entry is permitted, the entire support column is inserted into the pipe.

[0003] On the other hand, Patent Document 1 describes an invention related to a support column that can be constructed without digging a cylindrical hole in the ground and can be easily attached and detached. The detachable parking support column described in Patent Document 1 is configured such that a locking plate provided at the lower end of the support column body is inserted into a guide hole of a circular flange plate-shaped substrate (support column mounting plate) fixed to the ground and rotated to be locked.

[0004] Meanwhile, Patent Documents 2 and 3 describe inventions in which a sound is emitted when a vehicle contacts a support column to notify the driver. The parking lot sounding marker column described in Patent Document 2 is provided with a pendulum 12 that swings and makes a striking sound due to inclination inside a hollow pole 11 of the pole, so that it can be surely known to the driver when the vehicle hits during the guidance of the vehicle in the parking lot. Further, the guard post described in Patent Document 3 is configured to protect the rack by suspending a weight 60 that can swing horizontally inside a hollow main pipe 10 of the guard post and notifying the operator of a collision with a cargo handling vehicle.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The detachable parking post described in Patent Document 1 can be easily attached and detached, but there is a possibility of theft of the post itself. Of course, although the post body and the substrate are fixed by locking with a locking plate, there is also a possibility that the substrate fixed to the ground may be stolen as a whole. In addition, if the post is removed, there is also a risk that the vehicles in the parking lot may be stolen.

[0007] On the other hand, the inventions described in Patent Documents 2 and 3 are configured to make a sound when a vehicle contacts the post to notify the driver, and are not intended to prevent theft of the post itself.

[0008] The present invention solves the above-mentioned conventional problems and provides a car stopper capable of generating a sound effective for preventing theft of the post.

Means for Solving the Problems

[0009] In order to solve the above problems, the car stopper of the present invention comprises a post having a vertical shaft member and an engagement plate provided at the lower end of the shaft member, and a substrate having an engagement hole through which the engagement plate can be inserted. The post is detachably attached to the substrate by rotating the shaft member with the engagement plate inserted through the engagement hole. The car stopper is characterized in that a weight that contacts the inner wall of the post and generates a sound when the post swings is suspended inside the post.

[0010] Preferably, a plurality of the weights are arranged so as to surround the shaft member.

[0011] Preferably, the suspension lengths of the plurality of weights are different.

Advantages of the Invention

[0012] The vehicle stopper of the present invention comprises a support column having a vertical shaft member and an engagement plate provided at the lower end of the shaft member, and a substrate having an engagement hole through which the engagement plate can be inserted. Then, the support column can be detachably attached to the substrate by rotating the shaft member with the engagement plate inserted through the engagement hole, and the substrate and the support column can be easily detached. On the other hand, since a weight that abuts against the inner wall of the support column and generates a sound when the support column swings is suspended inside the support column, when someone tries to steal the support column, the sound will intimidate the thief and, if it is in a home parking lot or the like, it can also notify the owner who is nearby.

[0013] Also, by arranging a plurality of weights so as to surround the shaft member, the shaft member will not interfere with the suspended weights, and by using a plurality of weights, sound can be effectively generated.

[0014] In addition, since the suspension lengths of the plurality of weights are different, the timing at which the weights abut against the inner wall of the support column when the support column swings becomes complicated, and sound can be generated more effectively.

[0015] Thus, according to the present invention, it is possible to provide a vehicle stopper capable of generating a sound effective for preventing theft of the support column.

Best Mode for Carrying Out the Invention

[0017] Next, with reference to FIGS. 1-5, a vehicle stopper according to an embodiment of the present invention will be described. By installing the vehicle stopper at the entrance of a parking lot, park, etc., it is possible to prevent the intrusion of vehicles and the like. Also, if it is installed in a parking lot at home or the like, it is effective in preventing theft of automobiles.

[0018] FIG. 1 is a front view showing a vehicle stopper 100 according to this embodiment. The vehicle stopper 100 is composed of a support column 10 and a substrate 20.

[0019] FIG. 2 is a (a) front view, (b) plan view, and (c) bottom view showing the support column 10. The support column 10 is a hollow cylindrical body, and a handle 12 for lifting is provided on the upper surface 11. Also, a keyhole 13 is provided on the upper surface 11 so that a key (not shown) can be inserted. The keyhole 13 is connected to a shaft member 14 arranged vertically inside the support column, and a rectangular engaging plate 16 is provided at the lower end of the shaft member 14. The engaging plate 16 protrudes downward from the bottom surface 15 of the support column 10.

[0020] When a key (not shown) is inserted into the keyhole 13 and rotated, the connecting member 14 rotates horizontally, and accordingly, as shown by the arrow in FIG. 2(c), the engaging plate 16 rotates horizontally along the bottom surface 15.

[0021] FIG. 3 is a (a) front view and (b) plan view showing the substrate 20. The substrate 20 is a disk-shaped plate body, and an engaging hole 16 through which the engaging plate 16 of the support column 10 can be inserted is provided at the center. The substrate 20 is fixed to the ground at the installation location by an anchor bolt (not shown) or the like.

[0022] Then, the support column 10 is placed on the substrate 20 fixed to the ground. After alignment and with the engagement plate 16 inserted into the engagement hole 21, when a key is inserted into the keyhole 13 and rotated, the shaft member 14 rotates. Further, it rotates until the engagement plate 16 at the lower end of the shaft member 14 reaches a position where it cannot come out of the engagement hole 21, and the attachment of the support column 10 to the base plate 20 is completed. When removing, operate in the reverse of the above procedure. In this way, the vehicle stopper 100 is configured to detachably attach the support column 10 to the substrate 20.

[0023] Next, a sound generation mechanism effective for preventing theft of the vehicle stopper 100 will be described. FIG. 4 is an enlarged cross-sectional view showing the upper part of the support column 10. In FIG. 4, only the part below the upper surface of the support column 10 is shown as a cross-sectional view.

[0024] Inside the support column 10, three weights 31, 32, 33 are provided so as to surround the shaft member 14. In FIG. 4, due to the cross-sectional view relationship, the weight 33 provided on the front side is not shown, and only the weights 31, 32 provided on the back side are shown. Also, the weights 31, 32, 33 are collectively referred to as the weight 30.

[0025] The weight 30 is suspended inside the support column 10 from a suspension base 17 via a wire W. As the suspension base 17, a member for supporting the connection part of the keyhole 13 and the rotating shaft 14 at the upper part of the support column 10 can be used, but a member for suspending the weight may be separately provided on the inner wall of the support column 10.

[0026] FIG. 5 is a front view showing the weight 30. As shown in FIGS. 5(a), (b), and (c), the three weights 31, 32, 33 are common in the weight itself but different in the length of the wire W. That is, they are arranged in the order of W31 < W32 < W33 and become longer. As the weights 31, 32, 33, for example, lead used for fishing weights can be utilized. The upper end of the wire W is formed in a ring shape so as to be suspended from the suspension base 17.

[0027] When a thief grabs the support column 10 and causes it to sway, for example, the weight 30 abuts against the inner wall of the support column 10 and generates a sound. To increase the generated sound, it is preferable that the support column 10 be made of metal.

[0028] The vehicle stopper 100 according to this embodiment includes a support column 10 having a vertical shaft member 14 and an engagement plate 16 provided at the lower end of the shaft member 14, and a substrate 20 having an engagement hole 21 through which the engagement plate 16 can be inserted. Then, with the engagement plate 16 inserted through the engagement hole 21, the support column 10 is detachably attached onto the substrate 20 by rotating the shaft member 14, and the substrate 20 and the support column 10 can be easily detached and attached. On the other hand, since the weight 30 that abuts against the inner wall of the support column 10 and generates a sound when the support column 10 sways is suspended inside the support column 10, when someone tries to steal the support column 10, the sound intimidates the thief and can also notify the owner who is nearby if it is a home parking lot or the like.

[0029] Also, by arranging a plurality of weights 30 so as to surround the shaft member 14, the shaft member 14 does not get in the way of the weights 30 it suspends, and by using a plurality of weights 30, sound can be effectively generated.

[0030] Also, since the suspension lengths of the plurality of weights 30 are different, the timing at which the weights 30 abut against the inner wall of the support column 10 when the support column 10 sways becomes complicated, and sound can be generated more effectively.

[0031] Thus, the vehicle stopper 100 according to this embodiment is capable of generating a sound effective for preventing the theft of the support column.

[0032] The vehicle stopper according to the embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiments, and various other modifications are possible.

[0033] For example, in this embodiment, the number of weights 30 is three, but it may be one or more. However, in order to effectively generate the sound for theft prevention, it is preferable to provide a plurality of them.

[0034] Also, the suspension lengths of the plurality of weights 30 may be the same. However, in order to effectively generate a theft prevention sound, it is preferable to provide a plurality of them.

[0035] Also, the suspension position of the weight 30 is not limited to above the support column 10, and it may be in the middle or below. However, in order to effectively generate a theft prevention sound, the upper part where the swing amplitude during swinging is large is preferable.
