Description

  The present invention relates to a vehicle entry preventer for preventing unauthorized entry of a vehicle into a site.

  In order to prevent vehicles such as private land and public places from entering without permission, there is, for example, a method of displaying an obstacle such as a sign indicating entry prohibition in the center of the road surface.

  However, even if an obstacle is placed, a bill or the like can be easily removed, so it has not been very effective against a malicious intruder. In order to prevent unauthorized entry of vehicles, a method such as installing a gate can be considered, but there is a problem that the cost is high and the gate cannot be installed (for example, a farm that cultivates crops, etc.) Can not be adopted.

  The present invention has been made in view of the above circumstances, and the problem is that a vehicle entry prevention device that can effectively prevent unauthorized entry of a vehicle and can be used in any place. At an inexpensive cost.

In order to solve the above problems, a vehicle entry preventer according to the present invention is:
A main body extending in a rod shape;
A support part for rotatably supporting both ends of the main body part;
A vehicle entry preventing protrusion integrally attached to the surface of the main body,
When the main body portion is in the first posture, the protrusion is allowed to enter the vehicle, and when the main body portion is rotated from the first posture to the second posture, the protrusion is entered into the vehicle. And a lock mechanism that locks the main body in the second position.

  According to such a configuration, both end portions of the main body portion extending in a rod shape are rotatably supported by the support portion. A protrusion is integrally attached to the surface of the main body, and this protrusion functions to prevent the vehicle from entering. When the main body portion is in the first posture, the protrusions are allowed to enter the vehicle, and the protrusions do not interfere with the vehicle entry. When the main body portion is rotated from the first posture to the second posture, the projection is in a posture that interferes with the approach of the vehicle. And when it is set to the 2nd attitude | position, the lock mechanism for locking this attitude | position is provided. Therefore, the state where the entry of the vehicle is blocked cannot be easily released, and the vehicle entry can be effectively prevented. According to the said structure, the support part which supports a main-body part rotatably is just provided, and it can be set as the structure which is simple and does not cost. As a result, it is possible to provide a vehicle entry preventer that can effectively prevent unauthorized entry of the vehicle and can be used in any place at a low cost.

  In the present invention, it is preferable that a plurality of the protrusions are attached to the main body portion, and the tip portion thereof is formed in a sharp state.

  By attaching multiple protrusions to the main body, it is possible to more effectively prevent the vehicle from entering, and if the tip of the vehicle is sharpened, the tire of the vehicle that has entered without permission is punctured. Thus, escape can be prevented.

  In the present invention, it is preferable that the lock mechanism is provided in one of the pair of support portions that support the main body portion.

  In order to rotatably support the main body, support portions are required at both ends of the main body, but the lock mechanism may be provided for one of the support portions. Thereby, the second posture can be locked. Further, since the lock mechanism is provided only for one of the support portions, the configuration of the vehicle entry preventer can be simplified.

  The support in the present invention is composed of a rectangular column support portion having a rectangular or square cross section, and a cylindrical support portion having a circular cross section fixed in a vertical posture with respect to the prism support portion, and at the end of the cylindrical support portion. It is preferable that the end portion of the main body portion is fitted rotatably.

  According to this configuration, the entire vehicle entry preventing device can be installed on the road surface or the ground in a stable state by the rectangular column supporting portion having a rectangular cross section or square. And a main-body part can be rotatably supported by a cylindrical support part.

  A preferred embodiment of a vehicle entry preventer according to the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing the configuration of the vehicle entry preventer. FIG. 2 is a perspective view showing an external configuration of the vehicle entry preventer.

  In FIG. 1, the vehicle entry preventing tool A includes a main body 1 extending in a rod shape, and a first support 2 and a second support 3 that support both ends of the main body 1. The 1st support part 2 is comprised by the prism support part 2a and the cylindrical support part 2b, and the cylindrical support part 2b is integrated by welding inside the prism support part 2a. The 2nd support part 3 is also comprised by the prism support part 3a and the cylindrical support part 3b, and is integrated by welding similarly to the 1st support part 2. FIG. These members are made of steel, and the surface is appropriately plated or painted.

  The main body 1 is formed in a cylindrical shape, and both end portions 1a and 1b are fitted into cylindrical support portions 2b and 3b, respectively, and are rotatably supported. The length of the main body 1 in the axial direction is set to a length of about 1.5 m to 2 m, and can be determined in consideration of the width dimension of the vehicle. The main body 1 is supported at both ends 1a and 1b so as not to come out of the cylindrical support portions 2b and 3b.

  Four protrusions 1c are integrally attached to the outer surface of the main body 1 by welding or the like. As shown in FIG. 4, the protrusion 1c is coupled so as to penetrate the main body 1 and is welded at two locations 1d and 1e. The protrusion 1c is a small-diameter metal shaft member, and its tip is sharply formed. The main body 1 is rotatable with respect to the support portions 2 and 3, and FIG. 2A shows a second posture in which the protrusion 1 c faces upward, and the protrusion 1 c obstructs the vehicle from entering. To prevent. FIG. 2B shows a first posture in which the protrusion 1c is laid on the road surface or the ground. In this state, the vehicle is allowed to enter. The number, length, material, arrangement interval, and the like of the protrusions 1c can be determined as appropriate.

  Moreover, when the main-body part 1 is made into the 2nd attitude | position, the locking mechanism for locking this is provided. Specifically, a hole 3 c is formed on the surface of the cylindrical support portion 3 b of the support portion 3, and a bolt 4 is inserted from the hole 3 c and screwed into a female screw formed on the end surface of the main body portion 1. Thereby, the 2nd attitude | position shown to Fig.2 (a) can be locked. When returning to the first posture, the bolt 4 is removed, and the main body 1 may be rotated so as to be in the posture of FIG.

  FIG. 3 is a diagram showing a specific example of use of the vehicle entry preventer A shown in FIGS. 1 and 2. The vehicle entry prevention tool A can be used by being installed under the vehicle passage plate 10 as shown in FIG. The vehicle passage plate 10 includes a flat surface portion 10a and a pair of slope portions 10b connected to the flat surface portion 10a. Moreover, the support part 10a is integrally connected by the both sides of the plane part 10a.

  A rectangular slit 10c is formed in the inclined surface portion 10b on the vehicle entry side. The slit 10 c is a hole for projecting the protrusion 1 c of the main body 1. In addition, a hole 10d is formed in the plane portion 10a, and is a hole for operating the bolt 4. The shapes of these slits 10c and holes 10d can be changed as appropriate.

  4 is a cross-sectional view of the usage example of FIG. 2, in which (a) shows a first posture and (b) shows a second posture. In the case of (a), since the protrusion 1c does not protrude from the surface of the vehicle passage plate 10, the vehicle can pass smoothly. On the other hand, in the case of (b), the protrusion 1c protrudes from the surface (slope part 10b) of the vehicle passage plate 10, and if the vehicle tries to pass through forcibly, the protrusion 1c may become an obstacle and cause the tire to puncture.

  A bill 11 is placed on the front side of the vehicle traffic plate 10 to recognize that entry is prohibited.

  For example, when used on the site of a factory or company in the manner shown in FIG. 3, while the factory is in operation, it is set as shown in FIG. 4 (a) and the vehicle enters the site. Allow that. On the other hand, at night when the factory does not operate, the factory worker sets the vehicle entry preventive tool A as shown in FIG. That is, the main body 1 is rotated and the main body 1 is locked by the bolt 4 so that the protrusion 1c is in the second posture. Thereby, the protrusion 1c protrudes at night, and unauthorized entry of the vehicle can be prohibited. Then, when the worker goes to work in the morning, the bolt 4 may be removed and returned to the first posture shown in FIG.

<Another embodiment>
In the present embodiment, the main body 1 is only rotationally supported with respect to the support portions 2 and 3, but may be configured to be extendable and contractable in the axial direction with respect to the support portions 2 and 3.
