Bollards The Space Is Full Of Compressed Material

- Jul 04, 2017-

There are many safety bollards and similar structures that are used to prevent the entry of vehicles for some reason. Some of these safety bollards are specially designed to prevent driving robberies and various other attacks using mobile vehicles. Most of the current pillars available to the public are made of steel and are usually filled with concrete-type mixtures, which are quite successful in preventing the transport of vehicles into protected areas. However, these types of bollards can be easily cut by using a variety of tools that include powerful petrol horn or oxygenated acetylene welding equipment. While these tools may be very noisy and will still cost the operator for a few minutes to cut the guard, it is usually less than the response time of the police or security service, giving enough time to enter a zone. It is therefore an object of the present invention to provide a bollard that is more resistant to cutting than those currently known, or at least one substitute for a currently known bollard.

Thus, according to the first aspect of the present invention, although this is not necessarily the most general, nor is it only one aspect of the present invention, the present invention provides a safety pillar first upright hollow member having a defined An outer wall; a second vertical longitudinal member disposed within the cavity; and a biasing means associated with the second vertical longitudinal member, the biasing means being capable of biasing the second vertical longitudinal member The Preferably, the second vertical longitudinal member is in the form of a material that adequately fills the cavity, the material

Good at compression. Preferably, the bollard further comprises a platen disposed at a longitudinal end of the material, the biasing means being in the form of a spring, the spring being capable of applying a pressure towards the material to the platen. Preferably, the bollard is embedded in a cave of a floor, and the platen and the spring are disposed within the cavity below the surface to provide upward pressure to the material. Preferably, the material is a resin mixture. Preferably, the safety bolls further comprise a central upright longitudinal tube defining a core of the bollard. Preferably, the first upright hollow member is made of steel. In an alternative embodiment, the second vertical longitudinal member is in the form of at least one vertical longitudinal member longitudinally disposed within the cavity, wherein the at least one member is associated with the biasing means for biasing in a longitudinal direction Said at least one component.

Preferably, the Bollards is embedded in a hole in the ground and each of said biasing means is in the form of a spring disposed within said cavity below said surface, said spring being movable in said at least one vertical The component provides upward pressure. Preferably, the bollard includes a cap at its upper end and each of said vertical longitudinal members comprises a metal shell having an inner core adjacent to said cover at its upper end. Preferably, the safety pillow comprises a plurality of second vertical longitudinal members disposed circumferentially symmetrically within the cavity. Preferably, the space between the cavity and the second upright longitudinal member is filled with a material that is good at compressing. Preferably, the material is concrete. Optionally, the material is a heat resistant resin mixture. Preferably, the safety bolls further comprise a central upright longitudinal tube defining a core of the bollard. Preferably, the first upright hollow member is made of steel. Preferably, the bollard is embedded in a cave of a ground, the bollard comprising a horizontal member disposed at a lower end of the bollard, and the ground cave comprises a locking mechanism that engages the vertical And thereby locking the bollard in the bore, the locking mechanism including an arm for engagement between a first position and a second position in which the arm prevents the vertical The vertical movement of the member and the Bollards, and in the second position the vertical member and the Bollards are vertically movable. Preferably, the arm is movable between the first and second positions by using a vertical joystick accessible from the outside of the Bollards and a associated lever connecting the joystick to the arm, The vertical joystick moving between the upper and lower positions causes the arms to rotate between the first and second positions. In a further form of the present invention, there is provided a safety bollard first upright hollow member having an outer wall defining a cavity; a second upright hollow member disposed within said first upright hollow member, said The second upright hollow member having an outer wall defining an inner core of the bollard; the filling material being longitudinally disposed between the first and second walls, the filling material being good at compressing; and a material associated with the filler material , Said biasing means being capable of longitudinally biasing said filling material. In yet another further form of the present invention, there is provided a safety bollard first upright hollow member having an outer wall defining a cavity; a second upright hollow member disposed within said first upright hollow member, The second upright hollow member having an outer wall defining an inner core of the bollard; at least one vertically extending longitudinal blocking rod disposed between the first and second walls; and a second, And a biasing means for longitudinally biasing said blocking rod.
