Description

[Detailed description of the invention] foldable security fence FIELD OF THE INVENTION The present invention relates to a foldable security fence, and more particularly to a foldable security fence for forming a fence or obstacle. Concerning defensive fences that have become obsolete or defensive fences for signs.

More specifically, but not exclusively, the present invention provides for This is to protect them from falling into trenches, excavations, etc., and is generally used in garages. It is intended for temporary protection of permanent excavation trenches such as drill bits.

However, the fence of the present invention is suitable for platforms, terraces, loading piers, etc. In addition to providing temporary obstructions to parking lots, sidewalks, work areas, etc. It can also serve as a simple shelf support for signs.

The fence for the garage bit is for example a rail, sub-rail and prince (on the floor). (rails provided at the points of contact). Such fields are used for bit usage. must be easy to install and remove so as not to interfere with No.

Therefore, French Patent No. 2621346 and French Patent No. 26 by the inventor of the present invention Foldable type fences, such as the fence described in No. 61932, have already been proposed. Ru.

The disadvantage of traditional configurations is that for the folded fence to form a predetermined site on a bit It was necessary to provide camps and/or require civil engineering works.

The fence according to the invention makes it possible, inter alia, to eliminate the above-mentioned disadvantages. .

In fact, the present invention provides a foldable structure comprising at least one rail and a subrail. In a defensive fence, the rails are spaced apart from each other and are each connected by an end. supported by at least two mechanical diamond-shaped assemblies of four pivoted arms; The above rail is held at one side of the joint of each rhombus assembly, i.e. the rail joint. The opposing or ground joints may be fixed to the ground or is fixed to an element that is to be placed or fixed on the ground, and the above subrail is consisting of at least one rod parallel to said rail, each said rod having a rhombic shape. Cross the other two joints of the assembly, i.e. the subrail joints, with less protection. At least one locking system is provided to ensure that the device remains in the position of use. It is characterized by

This type of anti-ADI is expandable and retractable in the height direction, and the rails and subrails are made of lead. It can be seen that it rises and falls in the vertical direction (when installed horizontally).

According to a preferred embodiment, the locking system is arranged in a threaded part of the rod of the sub-rail. Place the threaded ring that now engages the subrail joint against each rhombus assembly. at least one of the operators.

In this case, more preferably, a rotational drive for engaging with the rod of the sub-rail further comprising means for displacing the sub-rail joint by rotating the rod; Avoid or bring the rail joints closer together, and even bring the rail joints and ground joints closer together. I'll keep you away. Also preferably, the rod of the sub-rail is connected to each rhombus assembly. In contrast, the threaded part for only one of the above sub-rail joints and the other one sub-rail joint, and this smooth part has a ring. , the rod of the sub-rail slides freely inside the ring.

According to another embodiment, which may be manual, the locking system is The said subrail is attached to the rhomboid assembly and to at least one of the subrail joints. a pawl adapted to engage at least one groove in the rod of the rod; The above rod rotates so that the above claw can be unlocked by simply rotating it. It is now possible.

In this case, for example, the sub-rail is located at a position where the groove rotates toward the pawl. and at least one counterweight for holding the head.

The above-mentioned defense fence is further provided with mutual rotation through means for rotating the above-mentioned sub-rails at any time. It consists of a plurality of defensive fence units connected together, and at least one of the above defensive fence units is One unit may also be provided with rotational locking means.

According to another particularly advantageous embodiment, the locking system is push-pullable. A jack is provided on at least some of the rhombus assemblies, the rod of the jack being connected to the rhombus. It acts on one of the arms of the shape assembly, and the joint of the above subrail is attached to the above subrail. It is attached so that it can slide freely, and the above-mentioned sub-rail joint can be moved away by the operation of the above-mentioned jack. Avoid or bring the rail joints closer together, and even bring the rail joints and ground joints closer together. I'll keep you away. In this case, preferably, the cylinder of the jack has a hollow surface. and parallel to the sub-rail and rail, and the above-mentioned jack at least one rod on one of the arms proximate to the ground joint of said rhombic assembly; It is pivotally connected via a link rod.

The end of the rod of the jack is, for example, connected to the jack through at least one bearing roller. It is pivotally attached to the link rod.

In particular, at least some rhombic assemblies to ensure a sufficiently parallel rise of the rails One of the two joints of the body subrail is connected to each other by a connecting bar. It is preferable that Also, preferably, some of the joints of the sub-rail The joint is specifically biased by a compression spring that serves as a damping means for the descent. .

To enable various applications, the rods of the above sub-rails are rotatably joined. It has multiple units connected to each other by sections, forming a polygonal defensive fence. Preferred embodiments are those in which it is possible to

The ground joint is fixed to a plinth, for example forming at least one prince, The pedestal is fixed or placed on the ground.

The pedestal may have an inverted T-shape or a U-shape.

The pedestal is further placed in an excavated groove formed for the pedestal. It is better.

In this case, according to one embodiment, the pedestal is for example attached to an element forming a lamp. Thus enclosed on both sides of its length, said pedestal is surrounded by the least of said elements placed on the ground. Both are pivoted to one element, and the defensive fence is forced down towards the pivoted element. when the other element lifts up.

According to another application, both ends of said rail are slidably mounted on two lateral supports. one of the above-mentioned supports (both of which act on the above-mentioned rail to form a defensive fence) Means are provided for actuation.

The invention will be understood and other features will become apparent from the following detailed description, taken in conjunction with the accompanying drawings. It will become clear.

Figures 1, 2 and 3 are shown in three positions, namely low position, intermediate position and Figure 3 shows the inventive anti-wJl in a high position.

4, FIG. 5, and FIG. 6 are diagrams corresponding to FIG. 11, FIG. 2, and FIG. An example is shown.

FIG. 7 partially shows another embodiment with another locking system.

Figure 8 shows a particular connection between two fence units.

FIG. 9 illustrates an example of an application made possible by the type of connection shown in FIG.

10 to 15 illustrate possible variations from the embodiments shown in the figures described above.

The anti-rIJtIl according to the present invention can be fixed on the ground or The pedestal 1 that has been placed on it and is now integrated with the ground, and the bar-shaped handrail (In each embodiment, the same members are given the same reference numerals.) (closed).

The rails 2 are foldable to form rhomboid assemblies 3 and 3'. It is movably attached to the pedestal l by an arm.

In the embodiment of FIGS. 1 to 3 there are two rhomboid assemblies 3, and in the embodiment of FIGS. 4 to 6 there are two rhomboid assemblies 3. uses three rhombus assemblies 3' (of course it is possible to have more rhombus assemblies). ).

As shown in the drawings, each rhombus assembly 3.3' is supported by four pivot arms. It is composed of

The pedestal l and the rail 2 have members 4 and 5, respectively, with two parts of each rhombus assembly. Corresponding ends of the arms are pivotally connected to each member 4 and 5. Note that this is This is why materials 4 and 5 are called ground joints and rail joints, respectively. be.

In fact, the arms of the rhomboid assembly can be pivoted directly without intervening members 4 and 5. I understand that clearly.

The other two joints 6.6' and 7.7' are connected to the subrail for reasons explained below. It's called a joint. In the embodiment of FIGS. 1 to 3, the subrail joints 6 and 7 are The joint 6 has a threaded ring 8, and the joint 7 has a smooth ring 9. do.

The rings 8 and 9 of the joints 6 and 7 are shaped like bars or rods. It is penetrated by a sub-rail.

The rod IO has a threaded part 10a and a smooth unthreaded part! Ob and Consisting of

The threaded part 10a comes to cooperate with the threaded ring 8, and the smooth part 10b becomes a smooth ring. It is designed to freely cross the Ning 9.

In this way, by rotating the rod 10 of the subrail, that is, tightening the screw. To move joints 6 and 7 closer together or farther apart by tightening or loosening them. and moving the joints 4 and 5 closer together or farther apart. In addition, the rod 10 of the rail 2 and sub-rail can be raised or lowered. It turns out that you can do it.

In order to carry out the above-mentioned rotation, an electric motor 11. Hydraulic motor, pneumatic motor or is equipped with other suitable motors.

The dimensions are such that all elements fit into the pedestal l in the folded state (Figure 1). It looks like this.

It can be seen that the sub-rail rods have multiple functions here.

First, let's construct the sub-rails that are necessary for the protection of the fence. They also constitute the control member and the locking member of the fence.

In use, several possible heights can be obtained. FIG. 3 shows the thread of the rod 10. It shows the maximum height with respect to the length provided in the carved part.

However, it is clear that the rod IO may also be threaded all the way through.

In the embodiment of Figures 4 to 6, the subrail joints 6' and 7' are is similarly traversed by rod 10'. However, each joint 6' and 7' cross the corresponding opening groove 10'a provided in the above-mentioned rod of the sub-rail. (See also FIG. 12 for a perspective view).

Therefore, in this embodiment, there is neither a threaded portion nor a motor 11.

On the other hand, the two diamond-shaped assemblies 3' at both ends are provided with, for example, hydraulic jacks 26. It is being The cylinders of the jacks 26 are arranged so as to face each other within the pedestal 1. parallel to the pedestal 1, i.e. to the rod 10' of the rail 2 and sub-rail. arranged in parallel.

The rod 27 of the cylinder 26 is pivoted to a double link rod 29 via a bearing roller 28. It is worn. The link rod 29 is connected to the diamond-shaped group adjacent to the joint 4 on the ground. It is pivotally attached to one side of the three-dimensional arm. To avoid unnecessary duplication, reference numeral 2 7 to 29 are one of the jacks 26 provided in the diamond-shaped assembly 3' of FIG. It is attached only to jackpots.

Furthermore, in the particularly advantageous embodiment of FIGS. 4 to 6, the subrails of each rhombus assembly are One of the joints, that is, the joint 6', is connected to each other by a connecting rod 3o. There is.

The operation of the jack 26 acts on one of the arms of the diamond-shaped assembly at both ends, and the rail 2 and can cause the raising and lowering of the rod 10' of the sub-rail. I understand that. In this way, the system can assume the states shown in Figures 4 to 6. Wear. As in the embodiments described above, FIG. 4 shows the folded condition, with all elements It is housed inside the pedestal l.

The connecting rod 30 is designed to ensure a sufficiently parallel rise of the rail and sub-rail. It seems to be very effective. Furthermore, the connecting rod 30 is provided with a jack. It provides rigidity to the central diamond-shaped assembly 3'. This is because each diamond assembly It is clear that there is no need to provide a jack; three diamond assemblies and two jacks are required. The illustrated configuration that fosters luck is particularly interesting.

In addition, a compression spring (not shown) is provided in the opening groove 10'a to brake the downward movement and to brake the upward movement. is facilitated.

Furthermore, other position locking means may be provided, for example as shown in the embodiment of FIG. . In the embodiment of FIG. 7, the subrail joints labeled 61 and 7' are to cooperate with grooves 14 and 15 provided in the rod 10” of the subrail. It is provided with claws 12 and 13.

Furthermore, in this embodiment, grooves 14 and 15 rotate toward pawls 12 and 13. The sub-rail 10' is biased by the counterweight 16 so as to do so.

In this embodiment, it is sufficient to raise the rail 2 to cause the pawl to lock. minute, and to release the latch of the claw and fold up the fence, rotate the sub-rail lO'. I know what I have to do. Also, rail 2 may be raised by any means. It will be appreciated that this may be performed manually or may be performed manually.

Means for rotating the sub-rail lO' at any time is provided, and a plurality of the types of the type shown in FIG. It is also possible to imagine connecting defensive fences. These measures include, for example, It may be provided in the center weight 16. And for this purpose, cow The interweight 16 is provided with a connecting groove 16', as shown in FIG. moreover, In this case, a rotary locking means may be provided for one of the multiple defense fences. can. This rotary locking means may include, for example, at least one of the joints 6'' and 7''. Consists of a lock that can be operated by a key installed in the Protection (mm is the only key point) This locking means may also be provided in the case where the locking device is made of bare metal.

FIG. 8 shows a security fence of the type of FIGS. 1 to 3 (of course, FIGS. 4 to 6). (The same and similar measures may be used in the examples). However, the sub Rule 10 is a Cardan type joint or unino (-monkey). It consists of a plurality of units connected to each other by joints such as joints 17. Ru.

With such a configuration, in particular the fence of FIG. 9 with at least one joint 17 As schematically shown, bending becomes possible.

For this type of security fence, rail 2 and/or pedestal 11 units are required. (or even just one bent unit).

FIG. 9 already shows one application example. FIGS. 1O-13 illustrate other possible applications. An example is shown.

For example, a garage as shown in Figure 10 can be constructed using two fences as described above. The pit 18 can be protected (using the embodiments of FIGS. 1 to 3 by way of example). ).

Figures 1 to 10 show a steel plate made of inverted T-shaped (Figure 10) or L-shaped (Figure 9) shaped steel. It shows the pedestal ■ that makes up the rinse (the rail provided where it touches the floor).

On the contrary, FIGS. 1-15 show a pedestal 1 made of U-shaped section steel. .

The pedestal I shown in Figs. It is arranged between elements 19 and 20 of. The defensive fence in Figure 11 is shown in Figure 1. This is the type described with reference to FIGS. 3 to 3, and the type shown in FIG. This is the type described with reference to No. 6.

Also, the whole may form, for example, a restraining brake, and the rail 2 is sufficient to cover the pedestal l. It can be seen that the entire fence can be folded into the pedestal 1.

In the application example of FIG. 13, only one lamp element 19 is provided and the fence is For example, it is designed to serve as a disembarkation pier.

Figures 14 and 15 show a railing as already described, but with rail 2 It further includes two lateral struts slidably mounted at their ends. This way A defensive fence is, for example, a barrier that forms a doorway. By opening groove lO’a A very interesting example can be directly demonstrated using the embodiment of FIGS. 4 to 6 in which sliding occurs. Obtainable. For this purpose, it is sufficient to simply add the struts of FIG. 12.

In order to operate the guard 111111 shown in Figs. 14 and 15, it is necessary to Both have at least one jack on one side. This joke is , is adapted to act on rail 2. However, the structure shown in Figure 12 Using a structure, the actuating jack is disposed in the pedestal l as described above.

As in the case of Figures 11 and 12, the pedestal consists of two elements 19 and 1 forming the lamp. It is installed between 2.

Furthermore, as shown in more detail in FIG. At positions 24 and 25, they are respectively pivoted to elements 19 and 20.

Thus, if a car applies force to the protector in one direction or the other, Even if the defense tll rotates toward the element opposite to the direction of the car's arrival, other elements The element rotates and blocks the movement of the car from below.

It is clear that in this case it is possible to provide a joint only on one side.

In addition, upon rotation to lock the return to the initial position without special intervention A stand that can be expanded can be placed on an element that can be lifted up. stomach.
