Description

crowd control barrier

technical field of invention

This invention relates to improved barriers and components thereof, particularly but not exclusively to crowd control barriers used to define routes that pedestrians or vehicles should follow and to prevent access to certain areas, especially those that might be suitable for police or other An area patrolled by agency personnel.

There is an increasing need to utilize crowd control methods other than rigid or permanent substantially immobile fencing. Street demonstrators, sports game spectators, and other emotionally charged people can quickly form such a crowd that their progress cannot be stopped by available police or other regulatory agency personnel, thereby resulting in personal injury or property damage.

Background technique

Various portable or transportable barriers are known, but generally these are used to direct vehicular traffic or to protect persons from vehicular traffic, particularly where roadworks are in progress.

For example, Swiss Patent Applications No. 676864 and No. 683540 by SEROC SA illustrate a traffic barrier that has a concrete base and a pair of spaced rails placed above the base, but is low in height and can be easily climbed , so ineffective for crowd control, Energy Absorption System's European Patent Application No.589605 exemplifies a hollow barrier assembly for traffic control, but this assembly is also ineffective for crowd control because it can be easily climbed, the ridge provided The underparts allow an efficient grip for climbing.

Thus, there is a need for a novel form of barrier which can be quickly and easily erected at a desired location and which will prove effective for crowd control and it is therefore the primary object of the present invention to satisfy the need for such a barrier.

It is a further object of the present invention to provide conveniently sized barrier assemblies which can be easily assembled to form a crowd control barrier which, once positioned and interconnected, are adapted to be filled with liquid for added weight and stability, and can be vented after use to restore performance for transport to other locations.

A further object of the present invention is to provide a barrier assembly of such a design that maximum compactness can be obtained without undue bulkiness, but which cannot be climbed by rioters or loafers in normal conditions. It is a further object to provide barrier assemblies which, once attached to adjacent assemblies, cannot be easily dismantled by rioters or loafers or tipped over by such persons under normal conditions. Yet another object is to provide assemblies of the recited properties that allow supervisors to observe crowds through the assemblies, and/or be able to deliver commands easily, and/or wield weapons for visible intimidation, but without the ease of climbing due to crowds And the safety advantage is significantly reduced. Other objects and advantages of the present invention will be apparent from the embodiments described later.

In view of the foregoing and other objects, an aspect of the present invention consists essentially in a barrier assembly comprising:

an elongated hollow base portion suitable for placement on the ground or an equivalent surface and ready to be filled with liquid, preferably water;

an elongated upper portion disposed above the base portion; and

a wall mechanism connecting said base portion and said upper portion and forming a barrier to prevent pedestrians from passing therebetween, said upper portion having an outwardly and downwardly curved upper surface extending from one side of said wall mechanism to said The other side of the wall mechanism to make it difficult to grasp the upper portion, thereby preventing climbing of the barrier assembly.

In another aspect, the invention generally resides in a barrier assembly comprising:

an elongated hollow base portion suitable for placement on the ground or an equivalent surface and ready to be filled with liquid, preferably water;

an elongated upper portion disposed above the base portion; and

a wall structure connecting and forming a barrier between said base portion and said upper portion, said upper portion having an outwardly and downwardly curved upper surface extending from one side of said wall structure to the other side of said wall structure On one side, to make it difficult to grasp the upper portion, thereby preventing climbing of the barrier assembly, the wall mechanism includes a plurality of spaced apart elongate members or portions adapted to substantially prevent pedestrians from passing therebetween.

In another aspect, the invention generally resides in a barrier assembly comprising:

an elongated hollow base portion suitable for placement on the ground or an equivalent surface and ready to be filled with liquid, preferably water;

an elongated upper portion disposed above the base portion; and

a wall mechanism connecting said base portion and said upper portion and forming a barrier to prevent pedestrians from passing therebetween, said base portion and said upper portion having a lateral dimension greater than said wall mechanism to prevent climbing said barrier assembly.

In yet another aspect, the invention generally resides in a barrier assembly comprising:

an elongated hollow base portion suitable for placement on the ground or an equivalent surface and ready to be filled with liquid, preferably water;

an elongated upper portion disposed above the base portion; and

wall means connecting said base portion and said upper portion and forming a barrier therebetween, said base portion and said upper portion having lateral dimensions greater than said wall means, said upper portion having an outwardly and downwardly curved upper a surface extending from one side of the wall mechanism to the other side of the wall mechanism to make it difficult to grasp the upper portion, thereby preventing climbing of the barrier assembly, the wall mechanism comprising a plurality of spaced apart thin Elongate members or portions extending upwardly from said base portion to said upper portion are adapted to substantially prevent the passage of pedestrians therebetween.

Preferably, the upper portion is substantially cylindrical providing an up and down curved surface, making it even more difficult for a person wishing to climb. Also preferably, the upper surface of the base portion curves outwardly and downwardly, making it difficult for a person wishing to climb to stand stably thereon and effectively grip and climb the barrier assembly.

Preferably, the shape of the elongated member or portion enables an observer standing on the other side to see the area beyond this side of the barrier assembly, whereby the observer can view the area from a protected position on the other side. Determine crowd size, commotion and other relevant aspects on this side of the barrier assembly. Advantageously, the spacing and shape of the elongate members allows crowd control authorities, such as the police, to control riots and other disturbances, which authorities can, if desired, use water cannons or other devices to disperse crowds through these openings or spaces. Also preferably, said elongated members or portions are hollow so that they can be filled with liquid to increase the weight of the assembly while providing a strip between said base portion and said upper portion (both also in optimal form). are hollow) through which the entire barrier assembly can be filled with liquid from one injection hole.

Preferably, the barrier assemblies include coupling means for coupling one assembly to an adjacent assembly, and preferably such coupling means are adapted to prevent disengagement of an intermediate assembly from an adjacent assembly. In a preferred form, the coupling mechanism comprises a pair of aligned downwardly pointing upper and lower pins disposed on one end of the assembly and a pair of complementary aligned upper and lower sockets disposed on the other end whereby in use, Pins of one assembly are insertable into corresponding receptacles of an adjacent barrier assembly. It will be appreciated that in this form of the invention, assemblies must be coupled and disconnected from the free ends of a barrier comprising a plurality of barrier assemblies, the weight of each assembly being effective to prevent an intermediate assembly from being disengaged when filled with water. open. Secondly, in those forms of the invention in which the wall means comprises a plurality of spaced apart elongate members extending from a base portion to an upper portion, the coupling mechanism is arranged such that the end elongate members of one assembly are connected to the end elongate members of an adjacent assembly. The spacing of the end elongated members is substantially equal to the same distance of the elongated members of each assembly, whereby the visible performance is maintained through the wall mechanism of all parts of a barrier comprising a plurality of coupled assemblies, while adjacent The wall mechanisms of the barrier assembly cooperate to form a connected barrier of substantially evenly spaced components.

Preferably, the base portion is shaped at its ends to allow adjacent components to pivot in the horizontal plane to form barrier corners. In a preferred form, the ends are curved to allow pivoting through an angle of about 45 degrees so that adjacent barrier assemblies can enclose a minimum of 135 degrees, and in one such form the base portion The upper surface at both ends is substantially part-spherical and the ends of the upper portion are substantially hemispherical and adapted to abut against opposite ends of an adjacent barrier assembly.

In a practical embodiment, a typical assembly may be substantially square in side elevation, a suitable height of 2100mm to satisfactorily deter adults from climbing, and the same length for stability so that when filled with water Its weight will effectively prevent it from being tipped over by hand by some persons or groups of persons in the crowd. In such an exemplary embodiment, the base portion is a suitable semi-cylindrical shape surrounding a base or transverse diameter measuring 1200 mm, resting on a suitable supporting mechanism such as a pad with its curved surface at the uppermost , such that a wall structure comprising a plurality of vertically connected tubes protrudes from the uppermost central longitudinal axis of the base portion. The upper elongated section in this exemplary embodiment may be cylindrical with a diameter of about 600 mm, with its curved lower surface the width of the middle connecting the tubes, so that the sides are convex. It can be seen that in an exemplary embodiment, the dimensions of the barrier assembly portions are effective to substantially prevent the assembly from being tipped over by many persons without a machine, and to prevent, or at least largely prevent, climbing. Second, the size, proportions and curvature of the parts of the barrier assembly make it extremely difficult, if not impossible, to push a human chain one after the other into the assembly.

In another aspect, the invention generally resides in a barrier assembly comprising:

an elongated hollow base portion suitable for placement on the ground or an equivalent surface and ready to be filled with liquid, preferably water;

wall means extending upwardly from said base portion; and

An upper portion is disposed above said base portion and is operatively connected to said wall mechanism for rotation relative to said wall mechanism. In this form of the invention it is preferred that said upper portion comprises a roller or rollers. In one form the rollers are mounted on extensions of said wall means and are cylindrical with their axes of rotation substantially parallel to the longitudinal axis of the elongate base portion. In other forms, however, these rollers may be freely mounted for rotation within a disc formed in the upper end of the wall mechanism, and may be cylindrical or spherical. Also preferably, other corresponding features of the assembly are as described in relation to other aspects of the invention.

It will be appreciated that the barrier assembly in any of its above aspects may include other features, such as quick release fittings at the top and bottom, whereby water can be introduced or drained as required, and will be apparent from the following description Still other features of the present invention are clear.

Detailed description of the drawings

Referring initially to Figures 1 to 4, the barrier assembly, generally indicated at 10, includes an elongated hollow base portion 11 adapted to be placed on the ground and filled with water, connected by a plurality of spaced apart elongated tubes 17 Beyond the head to an elongated top section 13 , which is also semi-cylindrical and parallel to the bottom part 11 , these tubes form a barrier or wall generally indicated at 12 .

In this case, the overall height is nominally 2100 mm, the length is the same, and the flat bottom 14 of the base part 11 has a transverse width of 1200 mm. The upper or top section 13 has a smaller width, its semi-cylindrical upper surface 15 extending upwards from a lower plane 16 with a lateral width of, for example, 600 mm. The upper part 31 is arranged directly above the base part and is connected in the middle by pipes 17, in this case eight pipes with a diameter of 150 mm, which are equally spaced and the openings 18 between adjacent pipes are about 120 mm wide, so that the assembly The side-to-side field of view can be adjusted widely, and allows police or other authorities to brandish weapons, as well as prevent adults from passing between them. These tubes are hollow, they are adapted to be filled with water like the upper and base parts and at the same time provide a conduit between these two parts so that water only has to be pumped in from one place or the other to fill the whole assembly. In this embodiment there is an end flange 19 at each end to increase stability and its edges 20 are arranged tangent to the two semi-cylindrical parts 13 and 11 of the upper and base. As shown in Figure 1, there is an upper quick release fitting 21 so that the operator can open the inlet for water entry via, for example, a hose, and a lower quick release fitting 22 so that the operator can use a key to unlock the lock. Drain the water.

As shown in Figure 4, an assembly 10 may be connected to an adjacent assembly 10a with a detachable coupling 23 which engages from above between adjacent two assemblies where in normal use It is impossible to tamper with the couplings, which are designed to allow at least 10 degrees of movement between adjacent components, as clearly seen in Figure 4. Although the tubes in this embodiment are of circular cross-section, in other embodiments they can be adapted to the best molding technique as required, such as circular cross-section or rhombus or square or oval.

The components can be molded as a single piece using common rotational molding techniques of suitable plastics such as UV blocking polyethylene, but other suitable materials can be utilized and other molding techniques can be used, which are critical to the molding profession The personnel are obvious.

In the assembly modification 10b shown in FIG. 5, except that the width of the end flange 19a is reduced and its edge 20a is substantially vertical, all other parts are the same as before and have corresponding same reference numerals. It can be considered that the end The reduced area of the front flange can make it less accessible for someone who wants to climb. In both embodiments, it is clear that the base section gives maximum stability with a low center of gravity and "steps" not high enough to raise a person on the top of the ramp to less than 1500 mm (or five feet) from the very top. )the height of. The vertical tube 17 is of no help to the climber who will find that due to the nature and shape of the top section or upper part 13 they cannot grasp the top.

Referring now to FIGS. 6a-8, the barrier assembly 110 includes a semi-cylindrical elongated hollow base portion 111 and a substantially cylindrical upper portion 113 disposed directly above the base portion, both of which are separated by seven equally spaced tubes. 117, the tubes form a wall 112 with vertical passages 118 between adjacent tubes. In this embodiment, the tube 117 is substantially elliptical in cross-section, flares outwardly at its lower end to join the curved upper surface 115 of the base portion 111, and flares outwardly at its upper end to join the upper curved lower surface. . It can be seen that the upper surface of the upper portion curves outwardly and downwardly to each side of the tube 117 from a central plane extending vertically through the assembly along the length of the assembly, the lateral dimension of the upper portion being greater than that of the tube.

It can be seen that the major axes of the elliptical cross-section of the tubes 117 extend laterally of the barrier assembly, providing supplementary strength in that direction, while the view between the tubes is virtually unrestricted except for a tiny Regions may not be visible to viewers on the other side. Preferably, vertical pipes allow the use of water cannons or even other forms of crowd control implements through the barrier.

In this embodiment, as more clearly seen in Fig. 6b, the base portion 111 is curved at both ends and more or less part spherical at both ends. Likewise, both ends of the upper portion 113 are curved, substantially hemispherical due to the cylindrical shape of the upper portion. It will be appreciated that the curved shape of the base portion and upper portion enables the coupled barrier assemblies to pivot relative to each other in the horizontal plane to form a barrier corner as shown in FIG. 8 . In this embodiment, the curvature and coupling mechanism are such that adjacent barrier components can pivot to enclose a 135 degree angle, thus requiring only three components to form a 90 degree angle.

The barrier assembly of Figures 6a to 8 includes downwardly directed pins 130 and 131 projecting from one end of the base portion and upper portion respectively and aligned vertically and horizontally. These pins are adapted to be inserted into complementary receptacles 132 and 133 respectively formed in outwardly projecting lugs on the other end of the adjacent assembly, as shown in FIGS. 7 and 8 .

As can be seen in FIG. 7, the pins and sockets are arranged such that the spacing between adjacent end tubes 117 is substantially equal to the spacing between the intermediate tubes 117, whereby over the entire length of the barrier consisting of the two barrier assemblies The middle field of view is basically the same. It will also be appreciated that in the case of multiple assemblies coupled together, an intermediate assembly cannot be disengaged from its two adjacent assemblies because one barrier assembly must be lifted to release the pin from its corresponding receptacle, while lifting When one component is raised, the adjacent component at its other end will also be raised.

Referring now to the embodiment shown in FIGS. 9a to 9e and FIG. 10, the barrier assembly 210 includes a base portion 211 similar in shape to the base portion 111 described above and a plurality of tubes 217 upstanding from the base portion, the tubes 217 being similar to the tubes 117, However, their upper ends are interconnected by an intermediate portion 225 having substantially the same lateral dimensions as the tubes and forming a header. Opposed end flanges 236 and 237 and an intermediate flange 238 protrude upwards from the connecting portion 225 so that a cylindrical upper part 213 is rotatably mounted around an axis 239 supported on flanges 236, 237 and 238 in the middle of the bearing. Other forms of mounting upper portion 213, such as stub shafts and sockets, may be used if desired.

In this embodiment, it will be appreciated that any would-be climbers of the barrier assembly will be held back by the roll of the upper portion 213 making it impossible to grab hold. Next, it can be seen that the barrier assembly 210 includes pins and sockets 230 to 233 that are similar in shape to the pins and sockets 130 to 133 described with respect to the barrier assembly 110, respectively.

The barriers and components described above and illustrated are very effective in achieving the above objects for which the present invention was designed. They may also, with little or no modification, replace the water-filled pavement breakout assemblies currently used to define the edges of traffic routes, especially for example when roadworks are in progress, and it is believed that assemblies can be made with an empty weight of as little as 75 kg, making them very easy and quick to move for various purposes, while their water-filled weight can be about 500 kg, making them immovable when used for any particular purpose.

It is to be understood, of course, that the embodiments given herein are illustrative only and that many further modifications in construction details and design will be apparent to those skilled in the relevant art without departing from the broad scope and ambit of the invention, the invention An outline of has been presented in this paper.
