Description

[Detailed description of the invention] The present invention relates to an enclosing part such as a parking lot, and more specifically, the invention relates to an enclosing part of a parking lot or other enclosing place.
The present invention relates to an enclosing part that can be taken out and extended and used as an enclosing part when in use, and can be reduced and stored in a recess under the ground surface when not in use, does not impede the operation of automobiles, etc., and can be extended and contracted smoothly.

Recently, due to the lack of parking lots for cars, etc., part of the road is used as a parking lot for a certain period of the day, and a part of the site of a general house is used as a parking lot for a certain period of time, so that cars can park there. While it is not being used, it is being used for other purposes.

Furthermore, automobile roads themselves are turned into so-called pedestrian paradises on weekends and holidays, and automobile operations are temporarily suspended.

In these cases, a part of the road or site is temporarily surrounded by an encircling part, and at that time the enclosing part must be transported and encircled, and when it is no longer necessary, the enclosing part must be transported to a storage location. , these tasks are complicated and require a great deal of effort.

From this point of view, for example, as shown in Japanese Patent Publication No. 42-26598, a plurality of telescopic pillars are installed in advance under the ground surface of roads, etc., and when in use, each pillar is extended and raised above the ground surface. An enclosing section has been proposed that is used as fence posts, and when not in use, each post is reduced in size and stored below the ground.

This enclosing part can be permanently installed even in a temporary enclosing part, but since the pillars are cut out from the multiple removable cylindrical bodies, it lacks smoothness when expanding and contracting, and the relatively long pillars can be left on the ground as they are. To store it below, you have to dig deep beneath the surface.

The purpose of this invention is to solve the above-mentioned drawbacks, and specifically, it is designed to be used in enclosing areas such as parking lots, where the expansion and contraction of pillars, etc. is extremely smooth and easy, and there is no need to dig very deep below the ground surface for storage and installation. suggest.

Embodiments of the present invention will be described below with reference to the drawings.

In addition, FIG. 1 is a perspective view showing the whole except for a part when the enclosing part according to one embodiment of the present invention is expanded, FIG. 2 is a front view showing the whole, and FIG. 4 is a front view of a part of an example of the fixing mechanism of the enclosing part in FIG. 1; FIG.
It is a front view of the encircling machine shown in the figure when it is stored.

First, in FIGS. 1 and 2, the reference numeral 1 generally indicates a telescopic member that is connected to the pantograph mechanism, and when extended, it takes on the form of a column, and when contracted, it is housed in a recess 2 below the ground surface.

That is, the telescopic member 1 is a so-called pantograph mechanism in which a pair of links 3 are combined in a pantograph shape, and a frame 4 is interposed at each pivot point of this pantograph mechanism.

Further, a footboard 5 is rotatably attached to the upper end of the telescopic member 1, while the lower end is fixed in the recess 2.

This recess 2 does not need to be dug deep below the ground surface, and is dug shallow and wide as shown in Figure 1.
is rotatably fixed to the track 6a via a pivot point, and a roller 7 is pivotally attached to the tip of the other link 3 at the lower end, so that the roller 7 can move in the direction of the arrow with the track 6b as a running track.

A locking groove 8b and a locking groove 8 are provided at the front and rear ends of the running track 6b.
a, the roller 7 travels along the running track 6b and engages with the locking groove 8a during extension, and the elastic member 1 is in the extended state.
In other words, it is held like a pillar.

At the time of contraction, the roller 7 is engaged with the locking groove 8b, and is housed in the recess 2 in this state.

To explain in more detail, when the elastic member 1 is stored in the recess 2, each roller 7 engages with the locking groove 8b as shown in FIG. It is covered with a tread 5 and does not pose any obstacle to cars or people walking.

Further, when the link 3 is extended during use, the roller 7 runs on the running track 6b toward the locking groove 8a, and the third
As shown by dotted lines in the figure, each roller 7 is fixed by engaging with the locking groove 8a, and as a result, the extensible member 1 is extended into a column shape to form a surrounding machine.

As mentioned above, when the telescopic member 1 is constructed from a pantograph mechanism, the expansion and contraction is extremely smooth because it is controlled by the combination of links.Moreover, one of the links at the lower end of the pantograph mechanism is pivotally supported, and the other is freely movable by a roller. Because of this structure, the lower end link can be automatically locked during expansion and contraction.

The telescopic members 1 are arranged at predetermined intervals, and at this time, the upper end treads 5 are connected by a flexible member such as a chino 9, and by the extension of the telescopic members, the distance between each support is increased. A surrounding machine connected by Cheno 9 is formed.

As explained in detail above, in the present invention, a treadle is fixed to the upper end of a plurality of telescoping members, each of these treads is connected by a flexible member, and each telescoping member also includes a pantograph mechanism consisting of a combination of links. It is something.

Therefore, it is sufficient to dig a shallow recess under the ground surface for storage, and the extension of the telescopic member is extremely smooth due to the link movement. There is no problem because it can be done.
