BACKGROUND OF THE INVENTION
The present invention relates to a car stop embedded in a road, a parking lot, or the like, which can selectively switch between entry and intrusion prevention of a vehicle.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, car stops provided so as to be able to appear and disappear on roads and parking lots are known. The wheel stopper is composed of an outer cylinder having an opening on the upper surface and an inner cylinder housed in the outer cylinder. Usually, the inner cylinder is fitted in the outer cylinder so that the vehicle can pass therethrough, while the inner cylinder is pulled out from the outer cylinder and stopped, so that the vehicle is Will be blocked from entering.
[0003]
By providing such a car stop on a road, a parking lot or the like, it is convenient to selectively switch the vehicle entry and entry prevention depending on the situation.
[0004]
[Problems to be solved by the invention]
By the way, in this type of vehicle stop, the inner cylinder that protrudes outside in the approach-prevented state may be required to have various shapes such as a rectangular cylinder and other polygonal cylinders. In order to supply various types of car stops with different inner cylinder shapes according to such demands, it is preferable to make parts as common as possible in addition to the inner cylinder in order to reduce facility costs and manufacturing costs. In the conventional vehicle stopper as described above, the shape of the outer cylinder needs to be different for each product type according to the shape of the inner cylinder, and the common use has not been achieved.
[0005]
In addition, when the shape of the inner cylinder is to be changed after the car stopper is embedded in a road or the like, the outer cylinder once embedded must be dug up and another outer cylinder that matches the inner cylinder to be changed must be embedded. In other words, there is an inconvenience that it takes a lot of cost and time to change the specification.
[0006]
The present invention has been made in order to solve the above-described problems, and it is possible to easily correspond various types of planar inner cylinders to one type of outer cylinder, and the shape of the inner cylinder. It is possible to make the outer cylinder common to various types of different types, and also to simplify the work when trying to change the shape of the inner cylinder after embedding on the road etc. It is intended to provide.

(50) has an opening through which the inner cylinder (30) is inserted, and the rotary cover (60) and the locking member (70) are attached to the outer bush (40) via the inner bush (50). In addition, a gap (L) is separated between the outer surface of the cylinder (62) in which the inner cylinder insertion hole (62a) of the rotary cover (60) is formed and the inner surface of the inner bush (50).It is characterized by this.
[0008]
According to this invention, since the inner cylinder is fitted and inserted into the outer cylinder via the rotary cover having the inner cylinder insertion hole and the retaining member, the inner cylinder insertion hole even if it is one type of outer cylinder By selecting a rotating cover that matches the planar shape of the inner cylinder, it becomes possible to attach the inner cylinder to the outer cylinder without changing the outer cylinder, improving the selectivity of the shape of the inner cylinder and improving the outer cylinder. The cylinder can be shared. Therefore, conventionally, it is necessary to use an outer cylinder that matches the shape of the inner cylinder. For this reason, it is necessary to prepare an outer cylinder corresponding to various types of planar inner cylinders in advance. This eliminates the inconvenience of increasing manufacturing costs. In addition, when changing the planar shape of the inner cylinder with the outer cylinder already embedded, the rotating cover or the like can be replaced without having to dig up the outer cylinder and refill a new one. As a result, the existing outer cylinder can be used as it is, and the cost of changing the inner cylinder can be greatly reduced.
[0009]
Furthermore, since the rotation cover is rotatable around the cylinder core while being prevented from coming off by the come-off prevention member, even if the inner cylinder is a square cylinder, a predetermined surface of the inner cylinder is defined as the rotation cover. Can be directed in a desired direction.
[0010]
  Also,The outer cylinder is provided with an outer bush that covers the upper portion of the outer cylinder and an inner bush that is fitted into the outer bush, and the inner bush has an opening through which the inner cylinder is inserted, The stop member is attached to the outer bush via the inner bush.The
[0011]
  According to this,By manufacturing the outer bush and the inner bush separately from the outer cylinder, it is possible to adopt an inexpensive ready-made product as the outer cylinder, and the end portion has a structure that can be fitted with a rotating cover and a locking member. This contributes to a reduction in manufacturing cost compared to the case of manufacturing a special outer cylinder.
[0012]
  Further, a gap is formed between the outer surface of the cylinder in which the inner cylinder insertion hole of the rotary cover is formed and the inner surface of the inner bush.
[0013]
  In the present invention, a plurality of anchor fittings (43) protruding in the radial direction are disposed on the lower outer peripheral surface of the outer bush (40), and the through hole (22) of the outer cylinder (20) The outer bush (40) is fixed to the outer cylinder (20) with a screw (S1) and a nut (N) that pass through the through hole of the outer bush (40) and the through hole (43a) of the anchor fitting (43). At the same time, the anchor fitting (43) is fixed to the outer bush (40), and the outer bush (40) is prevented from coming off while being anchored in the ground by the anchor fitting (43). It can be configured.

[0015]
In the present embodiment, the outer cylinder 20 employs a commercially available synthetic resin tube having an outer diameter dimension of approximately 200 mm, a wall thickness of approximately 10 mm, and a length dimension of approximately 850 mm. The outer cylinder 20 is fitted with a dish-shaped bottom plate 21 on the bottom and fixed by welding, screwing, or the like to have a bottom as shown in FIG. Is to be blocked.
[0016]
The outer bush 40 is extended outwardly from an outer bush body 41 having an inner diameter dimension set so that it can be fitted to the outer cylinder 20 in sliding contact with the upper edge of the outer bush body 41. It consists of a thick ring 42. The inner diameter of the thick ring 42 is set to be the same as the inner diameter of the outer cylinder 20, and the outer diameter is set slightly larger than the outer diameter of the outer bush body 41.
[0017]
Therefore, by fitting the outer bushing body 41 to the outer cylinder 20, the lower edge part inside the thick ring 42 abuts on the upper edge part of the outer cylinder 20, and the outer cylinder 20 of the outer bushing 40 beyond this. It is designed to prevent the fitting to the. Further, a screw hole 42 a corresponding to a through hole 52 a of a flange portion 52 described later of the inner bush 50 is screwed on the upper surface of the thick ring 42.
[0018]
Further, a plurality of anchor fittings 43 are provided on the outer peripheral surface of the lower part of the outer bushing body 41 at equal pitches in the circumferential direction and project in the radial direction. It is designed to be retained in the state where it is buried in.
[0019]
A plurality of through holes 22 are formed in the upper portion of the outer cylinder 20 at equal pitches in the circumferential direction, and a through hole corresponding to the through hole 22 is formed in the outer bush body 41, With the upper portion of the cylinder 20 fitted in the outer bush body 41, the screws S1 are inserted into these through holes from the inner side of the outer cylinder 20, and the anchor fitting 43 is attached to the tip of the screw S1 protruding outward from the outer bush body 41. The outer bush 40 is fixed to the outer cylinder 20 and the anchor fitting 43 is fixed to the outer bush main body 41 by screwing the nut N onto the tip of the screw S1 after fitting the through hole 43a in the upper part of the screw. It is like that.
[0020]
The inner bush 50 is provided concentrically at the upper edge portion of the cylindrical inner bush body 51 and the outer bush body 41 whose outer diameter is slightly smaller than the inner diameter of the thick ring 42 of the outer bush 40. A flange portion 52 is provided. The inner diameter of the flange portion 52 is set to be the same as the inner diameter of the inner bush body 51, and the outer diameter is set to be the same as the outer diameter of the thick ring 42 of the outer bush 40. ing.
[0021]
An annular groove 53 is formed at the inner peripheral surface position of the upper surface of the flange portion 52. The annular groove 53 is formed by cutting out the edge portion so as to be perpendicular to the entire circumference. The annular groove 53 is for fitting the rotary cover 60.
[0022]
Further, as shown in FIG. 1, the inner bush main body 51 is formed with a guide groove 54 for guiding a tip of a locking pin 35 (described later) of the inner cylinder 30 cut from the lower edge. The guide groove 54 is formed in a pair of point symmetry on the peripheral surface of the inner bush main body 51 with respect to the cylindrical center, and has a lower spreading groove 54a extending in the vertical direction with a lower end opened downward, and the lower spreading groove. It consists of a circumferential guide groove 54b extending in the circumferential direction from the upper end portion of 54a, and a linear short guide groove 54c slightly extending downward from the end portion of the circumferential guide groove 54b.
[0023]
By pulling up the inner cylinder 30 upward, the tip of the locking pin 35 fits into the downward spreading groove 54a, and is continuously guided by the downward spreading groove 54a to reach the position of the circumferential guide groove 54b. In this state, the inner cylinder 30 is rotated clockwise around the center of the hole and then lowered, whereby the tip of the locking pin 35 is fitted into the short guide groove 54c through the circumferential guide groove 54b. The protruding state of the inner cylinder 30 is maintained.
[0024]
The rotary cover 60 includes a disc-shaped cover main body 61 fitted into the annular groove 53 of the inner bush 50 and a square tube 62 attached to the central portion of the cover main body 61 so as to extend downward. The cover body 61 has an outer diameter dimension set slightly smaller than an inner diameter dimension of the annular groove 53 of the inner bush 50, and a thickness dimension set to be the same as the groove depth of the annular groove 53. By doing so, the cover main body 61 is fitted in the annular groove 53 so that the upper surface thereof is flush with the upper surface of the flange portion 52 of the inner bush 50 and can rotate about the cylinder center. ing.
[0025]
  The rectangular tube 62 is for inserting and inserting the inner tube 30 in a slidable contact state. The installation position is set so that the center position thereof coincides with the tube center of the inner bush 50, and in plan view The inner dimension of each side is set to be slightly larger than the outer dimension of each side in a plan view of the inner cylinder 30, so that the inner cylinder 30 can be fitted into the inner cylinder 30 so as to be relatively movable. The upper opening of the present invention for fitting the inner cylinder 30 into the outer cylinder 20 is formed by the square hole 62a of the square cylinder 62.As is apparent from FIG. 3, a gap L is separated between the outer surface of the square tube 62 and the inner surface of the inner bush 50.
[0026]
The annular cover 70 is for preventing the rotating cover 60 from coming off by pressing the cover main body 61 in a sliding contact state from above, and the inner diameter dimension is the length of the diagonal line of the square hole 62a of the rotating cover 60. The outer diameter dimension is set to be substantially the same as the outer diameter dimension of the flange portion 52 of the inner bush 50 while being set larger. An annular weir 71 extending downward is provided on the outer periphery of the annular cover 70.
[0027]
The inner diameter dimension of the annular weir portion 71 is set slightly larger than the outer diameter dimension of the flange portion 52, thereby covering the annular cover 70 on the flange portion 52 of the inner bush 50 to which the rotary cover 60 is attached. The annular weir portion 71 is externally fitted to the flange portion 52, thereby preventing the annular cover 70 from being laterally displaced.
[0028]
In such an annular cover 70, a plurality of through holes 72 are formed at an equal pitch in the circumferential direction, while a plurality of through holes 52a corresponding to the through holes 72 are formed in the flange portion 52, The annular cover 70 is fixed to the inner bush 50 by screwing the screw S into the screw hole 42a of the outer bush 40 through the through holes 72 and 52a in a state where the annular cover 70 is put on the flange portion 52. Thereby, the rotation cover 60 is surely prevented from coming off.
[0029]
The inner cylinder 30 is formed by a square cylinder having a square shape in a plan view, the length dimension is set to be approximately the same as that of the outer cylinder 20, and the outer dimension of one side in the plan view is the rotation cover. The size is set slightly smaller than that of the 60 square holes 62a, so that it can be fitted into the square holes 62a in a sliding state.
[0030]
The inner cylinder 30 has a square lid 31 whose dimension in plan view is set to be equal to that of the inner cylinder 30, and this square lid 31 is welded to the inner cylinder 30 in a state where the upper opening is closed. As a result, the inner cylinder 30 is integrated. Two through holes 32 are formed at appropriate positions of the square lid 31, while an inverted U-shaped handle 33 is formed so that both sides are inserted into the through holes 32.
[0031]
The inverted U-shaped handle 33 is used for gripping the inner cylinder 30 when it is pulled out from the outer cylinder 20, and male screws are screwed on both sides thereof. The nuts N are screwed into the male screws and welded while the both sides of the male screw are inserted into the through holes 32 from above. It becomes possible to move up and down with respect to the lid 31.
[0032]
Then, the square lid 31 with the inverted U-shaped handle 33 is fixed to the top of the inner cylinder 30 by welding.
[0033]
In addition, through holes 34 are formed at appropriate positions in the lower position of the inner cylinder 30 and in the center positions in the width direction of the side walls facing each other, and each of the through holes 34 has one engagement. A stop pin 35 is inserted. The locking pin 35 is set to have a length slightly shorter than the inner diameter of the outer cylinder 20.
[0034]
Therefore, the inner cylinder 30 is fitted into the outer cylinder 20 from the upper or lower opening of the outer cylinder 20, and the inner ends of the locking pins 35 are adjusted so as to be accommodated in the outer cylinder 20, respectively. The cylinder 30 is mounted in the outer cylinder 20.
[0035]
In addition, a lock rod mounting hole 36 is formed at a position spaced apart from the through hole 34 in the inner cylinder 30 by a predetermined distance, and a lock mounting cylinder 36 a is interposed between the lock rod mounting holes 36. A predetermined lock rod 37 is provided in the lock mounting cylinder 36a.
[0036]
The lock rod 37 is for locking the state in which the inner cylinder 30 protrudes from the outer cylinder 20, and is inserted through one lock rod mounting hole 36 in a state in which the inner cylinder 30 protrudes from the outer cylinder 20 to the maximum extent. By pushing out the lock rod 37 to the outside, the push-out state is locked by a predetermined lock mechanism, and the push-out state is maintained unless an unlocking operation with a predetermined key is performed.
[0037]
Therefore, when the lock rod 37 is pushed out with the inner cylinder 30 protruding from the outer cylinder 20 to the maximum extent, the pushed-out portion of the lock rod 37 interferes with the rotary cover 60, thereby causing the inner cylinder 30 to be removed from the outer cylinder 20. It cannot be stored in the cylinder 20.
[0038]
4A and 4B are explanatory views for explaining the operation of the car stopper 10 of the above embodiment. FIG. 4A is a state in which the inner cylinder 30 is housed in the outer cylinder 20, and FIG. The state (c) being pulled out from the outer cylinder 20 shows a state where the protruding state of the outer cylinder 20 pulled out from the inner cylinder 30 is maintained.
[0039]
First, in the state shown in (a) of FIG. 4, the inner cylinder 30 is embedded in the outer cylinder 20 embedded in the ground so that the upper surface of the outer bush 40 is flush with the ground surface G. Is embedded in the ground as a whole, so that the vehicle can pass through the upper part without being aware of the presence of the car stopper 10.
[0040]
Then, when blocking the passage of the vehicle, the inverted U-shaped handle 33 may be picked up with a finger and pulled upward. Then, the inverted U-shaped handle 33 is once pulled upward from the square lid 31 of the inner cylinder 30 and can be gripped. Therefore, when the inverted U-shaped handle 33 in this state is gripped and pulled upward, FIG. As shown in (b), the inner cylinder 30 is exposed from the outer cylinder 20 to the outside. At this time, the both ends of the locking pin 35 provided in the lower part of the inner cylinder 30 are raised while being in sliding contact with the inner peripheral surface of the outer cylinder 20.
[0041]
When the locking pin 35 reaches the height level of the downward spreading groove 54a, the tip of the locking pin 35 is fitted into the downward spreading groove 54a, and then stops at the top while being guided by the downward spreading groove 54a. Therefore, any further extraction of the inner cylinder 30 is prevented. In this state, by rotating the inner cylinder 30 in the direction in which the circumferential guide groove 54b extends (in the example shown in FIG. 1, the direction in which the clock hand rotates in plan view), the rotation cover 60 rotates together with the locking pin 35. The tip rotates clockwise along the circumferential guide groove 54b and reaches the position above the short guide groove 54c.
[0042]
By stopping the pulling-up operation of the inner cylinder 30 in this state, the tip of the locking pin 35 is guided to the short guide groove 54c and is lowered until it comes into contact with the lower end position of the short guide groove 54c. As shown in (c), the state in which the inner cylinder 30 is pulled out from the outer cylinder 20 and protrudes upward from the ground surface G is maintained. As a result, the vehicle can be prevented from entering the predetermined area.
[0043]
As described in detail above, the vehicle stopper 10 of the present invention is provided with an outer cylinder 20 embedded in the ground with the upper opening facing upward, and an interior that can be projected and retracted through the opening in the outer cylinder 20. The rotary cover 60 is provided in the upper opening of the outer cylinder 20 so as to be rotatable around the center of the cylinder, and the rotary cover 60 is allowed to rotate. An annular cover (a locking member) 70 is provided to hold the edge portion of the inner cylinder 30 from the upper part and prevent it from coming off. Therefore, by selecting the rotation cover 60 that matches the planar shape (ie, square) of the inner cylinder 30, the inner cylinder 30 can be attached to the outer cylinder 20 without changing the planar shape of the outer cylinder 20 to a square. The selectivity of the shape of the inner cylinder 30 It is possible to improve.
[0044]
Therefore, conventionally, the outer cylinder 20 that matches the shape of the inner cylinder 30 must be used. Therefore, the outer cylinder 20 corresponding to the inner cylinder 30 of various planar shapes such as a square must be prepared in advance. Therefore, the inconvenience that the outer cylinder 20 becomes a variety of products and the manufacturing cost increases can be solved.
[0045]
Further, when the planar shape of the inner cylinder 30 is changed in a state where the outer cylinder 20 is already embedded, the rotating cover 60 is performed without performing a troublesome work of digging up the outer cylinder 20 and refilling a new one. It is possible to do so by replacing the inner bush 50, and it is possible to realize a significant reduction in the change cost when the planar shape of the inner cylinder 30 is changed.
[0046]
Further, since the rotary cover 60 can be rotated around the cylinder core while being prevented from being detached by the annular cover 70, even if the inner cylinder 30 is a square-shaped square cylinder in plan view, the inner cylinder The 30 predetermined surfaces can be directed in a desired direction along with the rotation cover 60.
[0047]
In the above embodiment, the outer cylinder 20 has an outer bush 40 that covers the upper portion of the outer cylinder 20, and an inner bush 50 that is fitted inside the outer cylinder 20 while pressing the outer bush 40. Since the rotary cover 60 and the annular cover 70 are attached to the inner bush 50, the outer bush 20 and the inner bush 50 are manufactured separately from the outer cylinder 20. It becomes possible to adopt a product, and contribute to a reduction in manufacturing cost as compared with the case of manufacturing a dedicated outer cylinder 20 having a structure that can be fitted with the rotating cover 60 and the annular cover 70 at the end. Can do.
[0048]
Further, since the annular cover 70 is formed of an annular body having an inner diameter that is slightly smaller than the outer diameter of the rotary cover 60, the entire circumference of the rotary cover 60 is held by the annular cover 70, which is an annular body. The wearing state can be made more stable.
[0049]
In addition, the outer cylinder 20 that is embedded in the ground is a conventional one, and an inner bush 50, a rotary cover 60, and an annular cover 70 are attached to the outer cylinder 20 so that a general round as an inner cylinder is obtained. In addition to the pipe and the square pipe of the present embodiment, various deformed pipes can be adopted, and the versatility of the car stopper 10 can be improved, and a novel design can be imparted to the car stopper 10. The same applies to the replacement of the inner cylinder.
[0050]
