Description

[Detailed description of the invention] (Industrial field of application, target) This invention relates to car stopping, and more specifically, to prevent vehicles from entering or driving into grounds such as parks, except in special cases. This invention relates to improvements in so-called movable car stops for preventing such problems.

(Prior Art) All conventional car stops of this type basically consist of a steel pipe foundation member that is buried almost vertically in the ground at a desired location, with only the head slightly exposed above the ground, and this foundation. A column member made of a steel pipe is removably fitted to the outer circumference or inner circumference side of the member head, and when it is desired to prevent entry or entry of automobiles, etc., the column member is fitted to the base member. At the fitting part between the head of the foundation member and the lower end of the column member,
A ring connected to the pillar member with a chain is inserted from one side into a predetermined through hole that is bored through the circumferential walls of both pipes almost horizontally in the diametrical direction, and is caused to protrude from the other side. For example, lock or drop a pointer pin into the hole provided at the tip of the finger, and screw it into a female screw threaded on the inner surface of the lumen having an opening at the tip of the finger; The retained set screw is further screwed in, and its tip is engaged with a notch cut in the middle position in the length direction of the pointer pin, thereby pulling out the inserted pointer itself from the through hole. ,In other words,
It is made so that it is almost impossible for anyone other than those involved to remove the column member from the foundation member.

However, if the pillar member of the movable car stop is removed from the head of the foundation member in order to allow vehicles etc. to enter and drive in for a predetermined period of time, the pillar member will be removed from the corresponding foundation member that forms a set with it. It is common practice to place the pin on the ground nearby, and to leave the pin, which is removed at that time, connected to the pillar member with a chain. in this case,
Locks, point pins, set screws, etc. are not left at the location, but are naturally kept by related parties, such as the park management personnel who performed the work to remove the pillar member from the foundation member. Even if this problem is unlikely to occur, as mentioned above, at least the ferrules that are left together with the column members at the site are simply connected to the column members with a thin chain. Although it is probably the result of a prank by a heartless person, there are many cases and possibilities of the chain being cut and carried away, resulting in the item being lost. Therefore, even if a column member is fitted to a foundation member, if the attachments or other accessories of the column member are missing, it will be difficult to use it as a car stopper, and the desired function will not be achieved. There are inconveniences and drawbacks such as not being able to do things.

(Purpose and structure of the invention) The present invention was made in view of the above-mentioned circumstances, and its purpose is to overcome the above-mentioned inconveniences and drawbacks that were unavoidable with conventionally known and publicly used movable car stops. almost completely removed, manufactured, handled,
To provide at low cost a movable car stop that is easy to operate, has little fear that essential accessories will be taken away or lost, and has excellent durability.

Therefore, the vehicle stopper according to the present invention has a tubular base member that is buried almost vertically in the ground and whose head is exposed above the ground by a small height, and is removably fitted into the head of the base member. In the car stop equipped with a tubular column member, the peripheral wall of the head of the base member has both ends of a groove-shaped member extending in a substantially horizontal direction with the open surface facing upward, and At the lower end peripheral wall, both ends of a rod member are arranged along both side walls of the groove-shaped member and extend upward near the bottom surface in a substantially horizontal direction.
At the same time, both ends of a female threaded member extending substantially horizontally are fixed to one side wall of the groove-shaped member and the peripheral wall of the head of the base member, and the rod is fixed in the female threaded member. A feature is that a male threaded member having a tip that can be advanced across the member to a position directly above the member is screwed together and housed.

(Embodiment of the invention) Next, a car stop as an embodiment of the invention will be specifically explained based on the drawings.

In other words, Fig. 1 is a partially longitudinal sectional front view showing the entire structure, and Fig. 2 is an enlarged longitudinal sectional view of the main part.
3, which shows a plan view of the cross section taken along the - line in FIG. Only a slight height is exposed above the ground surface 2a.

This foundation member 1 is installed above a crushed stone layer 3 that has been laid at an appropriate depth underground 2 and compacted.
An annular flange 1b is covered with concrete 4 of an appropriate thickness cast on the outside, and is welded to the outer surface of the peripheral wall of the head 1a at a position slightly above the ground surface 2a. Since it is in contact with and seated on the surface, it can be expected to be securely fixed.

On the peripheral wall near the upper opening edge 1c of the base member head 1a, both ends of a single steel plate groove member 5 extending substantially horizontally across the diameter of the opening are provided with the open surface 5a facing upward. Both are fixed in place.

Between one side wall 5b of this groove-shaped member 5 and the peripheral wall of the base member head 1a, there is a wall 1 extending substantially horizontally.
A female screw member 6 in the shape of a hollow cylinder of a book is placed horizontally. Both ends of the female threaded member 6 are fixed at approximately the center of the length of the side wall 5b and near the midpoint of the height h thereof so as to be approximately perpendicular to the side wall surface.

The column member 7, which is removably fitted to the outer periphery of the head 1a of the foundation member 1 whose interior is filled with concrete 4a up to the vicinity of the upper opening edge 1c, has a cross section with an inner diameter slightly larger than the outer diameter of the head 1a. It is circular, and its upper end is made of a sealed steel pipe, and its lower end has an open edge 7a.
Both ends of a bar member 8 made of, for example, a round bar, which extends substantially horizontally across the diameter of the opening, are fixed to the peripheral wall near the opening.

In addition, when fixing both ends of this rod member,
As clearly shown in FIG. 2, when the column member 7 is fitted to the head portion 1a of the base member 1, the rod member is inserted into the corresponding groove-shaped member 5 on its bottom surface 5c.
It is desirable to appropriately determine the height of the pillar member from the lower end opening edge 7a so that the pillar member is positioned above the edge.

A female threaded portion 6c having an appropriately smaller diameter than the hollow holes 6a and 6b is threaded between hollow holes 6a and 6b provided at both ends of the female threaded member 6 and each having an appropriate length. As a result, a circular step portion 6d is formed on the rear end side of the center hole 6a adjacent to the front end of the female threaded portion 6c.

Hollow holes 6a are formed in the side wall 5b of the channel member 5, the peripheral wall of the base member head 1a, and the peripheral wall of the lower end of the column member 7.
Or, through holes 9, 10, and 11 each having an appropriate inner diameter are bored at positions corresponding to holes 6b.

A male threaded member 12 is housed in the female threaded member 6 in a state in which it is always screwed together with the female threaded portion 6c (see FIG. 4).

This male threaded member has a male threaded portion 12a that is screwed into the female threaded portion 6c, and a tip portion 12b having a circular cross section and a head portion 12c having a square cross section are provided at both ends thereof.

The tip end 12b of the male threaded member 12 is formed so that its length is approximately equal to the inner width of the groove-shaped member 5, and its diameter is approximately equal to the outer diameter of the male threaded portion 12a. , as illustrated in FIG.
An annular groove 12d may be formed between the rear end and the annular groove 12d, and an annular locking member 13 such as a so-called snap ring may be fitted into this groove.

Since the hollow hole 6a provided at the distal end side of the female threaded member 6 is approximately equal in length to the distal end portion 12b of the male threaded member 12, when this male threaded member is in the state shown in FIG. 3, the open end of the hollow hole 6b For example, by inserting a box spanner (not shown) and engaging the square head 12c and twisting it back, the tip 1
2b is connected to the locking member 13, or if such a special locking means is not provided, the rear end of the tip portion is connected to the stepped portion 6d on the front end side of the female threaded portion 6c.
, and eventually the side wall 5 of the channel member 5
b Retracts from the inner surface and is completely housed in the hollow hole 6a.

(Operation of the invention) When attempting to fit the pillar member that has been removed to the foundation member in order to use the car stop configured as described above to prevent entry of automobiles, etc., the male threaded member 12 The tip end 12b of the base member is inserted into the head of the base member so that the rod member 8 can be fitted without any trouble between the left and right side walls of the groove-shaped member 5 which has been retracted into the hollow hole 6a of the female threaded member 6 in advance. 1a, specifically, the lower end portion of the column member 7 is fitted into the head of the base member while adjusting the circumferential position of the column member 7 relative to the groove-shaped member.

In this way, when the column member 7 is fitted to the head portion 1a of the corresponding base member 1 as specified, the through hole 11 to be bored in the peripheral wall at the lower end of the column member is formed in the peripheral wall of the base member head portion 1a. Then, if a suitable tightening tool (not shown) such as a box spanner is inserted through these holes 11 and 10, and the male threaded member 12 is screwed through the square head 12c, The tip 12b, which had been inside the hollow hole 6a, protrudes into the channel member 5 through the through hole 9 provided in the side wall 5b, further crosses the rod member 8 to a position directly above it, and then passes through the other side wall opposite Move forward until it almost touches the inside surface.

Therefore, the rod member 8 is engaged with the tip end 12b of the male threaded member 12, which is firmly connected to the head portion 1a of the base member 1, through the female threaded member 6 and the grooved member 5, thereby being pushed upward. Since displacement and movement are completely restrained, the column member 7, which is integral with the rod member, is also securely fixed to the foundation member, and can fully perform its function as a car stop.

In addition, in order to allow entry of cars etc., the pillar member 7
If you want to remove it from the head 1a of the foundation member,
In the same way as described above, insert a suitable box spanner or the like into the through holes 11 and 10 to open the square head 12.
c and then twist the male threaded member 12 back, the tip 12b that was just above the bar member 8
is retracted from within the groove-shaped member 5, fits into the hollow hole 6a, and releases the rod member from restraint, so that the column member can be easily removed from the base member.

Incidentally, in the above embodiment, the case where the column member is fitted to the outer peripheral side of the head of the foundation member is described;
This may be fitted on the inner circumference side,
Further, these members may not be made of steel pipes having a circular cross section, but may be made of aluminum alloy and having a rectangular cross section, for example. Generally, the female threaded member 6 and the male threaded member 12 are made of stainless steel, for example, and the other components are coated with appropriate paint on both the inside and outside surfaces. Note that it is extremely convenient to provide suitable through holes (not shown) in the side walls, both end walls, or bottom wall of the groove-shaped member 5 for cleaning the inside and discharging foreign matter such as rainwater and dust. .

(Effects of the invention) As detailed above, in the car stopper according to the invention, the insertion and removal of the column member into and out of the head of the base member is as follows:
This can be done reliably with the simple operations of screwing into the female threaded member provided on the head, screwing in the built-in male threaded member, and unscrewing it, and the removed column member can be placed directly on the ground at the site. Even in such cases, it is almost impossible to remove the male screw member, which is an essential accessory, from the head of the base member, so there is no fear that it will be taken away or lost.

Therefore, according to the present invention, the structure, handling,
It is easy to operate, and the inconveniences and shortcomings of conventionally known car stops of this type, such as the indispensable fittings and other accessories that are easily removed or lost, are eliminated, and in other words, their management is significantly easier. A special effect can be obtained in that a movable car stop that is easy to use and has improved durability can be provided at a low cost.
