Definitions

the invention relates to an impact absorber for motor vehicles on traffic routes, the impact of a vehicle by energy consumption, e.g. by deformation or by friction by means of a damping element, dampens.
the damping element is usually made of a plurality of successively arranged vertically standing tubes, which are lined up in front of a stationary support.
the pipe sections deform and convert the kinetic energy of the vehicle into deformation work, thereby damping the impact and braking the vehicle.
a supporting device by means of a permanently anchored in the building concrete block is unsuitable, since often the structural conditions do not allow a solidly anchored concrete support.
the invention is therefore based on the object to provide a crash cushion, in particular on special structures such as bridges and branches can be easily and inexpensively constructed and deployed on bridges, and at the same time can provide successful damping of an approaching vehicle.
a crash cushion for motor vehicles on roads which has at least one impact of a vehicle by energy consumption due to deformation and / or friction damping damping element, which is supported directly or indirectly by a dynamic catching device in the rear region of the crash cushion, wherein the collecting device has at least one rotatably supported supporting element and a support means likewise rotatably connected with the abutment means with direct or indirect contact with the at least one damping element.
the support element, against which the at least one damping element is supported is advantageously bent against a resistance whose overcoming is accompanied by a reduction in the kinetic energy of the impacting vehicle, by a rotation angle.
the support element and the abutment means are each rotatably mounted about a substantially horizontal axis, wherein the support element is held at the bottom by means of a rotatable about said horizontal axis fortification. Due to the bending during the turn energy is consumed again.
the support element is designed as a substantially straight Abstweilbalken which is held obliquely at an angle by means of a bendable metal mounting bracket and rotatably supports at its upper end the abutment means for the at least one damping element.
the inclination of the Abstauerbalkens allows this after in-function pedaling a controlled rotation of the Abstweilbalkens.
the support element may be beneficial to form the support element as an angled, substantially L-shaped Abstützbalken whose one downwardly projecting leg by means of a bendable metal fastener is held in a vertical position and rotatably supports the abutment means for the at least one damping element at the free end of the other leg projecting horizontally forward. If there is a maximum damping case, then the leg of the L which projects upwards after the rotation forms a stop for the moving system and builds up a last resistance to the movement.
the support bar can additionally be stopped by a bottom stop arranged in the bottom area, so that a further energy potential of the vehicle is again consumed by deformation work when bending this upwardly projecting leg.
the bottom stopper may also be in front of a damper in the direction of travel.
the impact damper is designed so that a main damping area and a collecting damping area are provided, the latter being supported by the support element.
the damper may be a unitary tube assembly, which may have any suitable subdivision.
the at least one support element in an impact by a vehicle with very high energy, can be bent up to a bending stop. The bending occurs only when the damping potential of the damping elements is exhausted.
the bottom is the bending stop.
damping means are provided behind the abutment means in the direction of impact, so that the abutment means is likewise dampable in the direction of impact when all preceding damping means are consumed. This considerably increases the damping potential of the crash cushion.
the attachment has at least one attachment flange extending in the direction of impact and fixed on the ground, the bottom attachment means of which are designed as predetermined breaking points which can break continuously in a progressive manner. It is possible to design the lying on the floor flange with a desired length in the direction of impact, so that a sufficient breaking capacity can be provided. It may be particularly favorable to provide a stopper in the floor area at a distance behind the bendable fastening as a stop for a horizontal movement of the bent-over support beams.
a special security can be provided by the fact that a device for preventing the separation of the construction is formed in the event of a collision, in particular on the collecting device. This ensures that due to the violence and the high energy consumption individual components can not solve and fly away.
Such a device for preventing the separation of a wire rope construction consist, wherein the essential elements of the construction can be pierced and held by several cables or a common rope.
Fig. 1 shows a plan view of an impact absorber 1 according to the invention with dynamic catching device 2.
the impact damper according to the invention is subdivided into a main damping area 1a and a collecting damping area 1b.
the invention is not limited to such a division into two parts, but may instead have any suitable configuration of a damper arrangement, that is to say with multiple subdivisions or in one piece, with the dynamic collecting device being arranged according to the invention at the end of the impact absorber.
the dynamic collecting device 2 is arranged in the collecting damping region 1b.
the crash cushion 1 has at least one damping element 3 that absorbs the impact of a vehicle by consuming energy as a result of deformation.
a plurality of damping elements 3 are arranged in series one behind the other as well as side by side in the main damping region 1 a such that the overall construction shows a V expanding in the direction of travel.
the arrangement of the damping elements 3 is supported against an end support 20.
the fall arrest area 1 b connects to the dynamic collecting device 2.
the dynamic collecting device 2 is equipped with at least one rotatably supported supporting element 5, on which a bearing means 6 is rotatably supported.
the dynamic collecting device 2 has a multiplicity of damping elements 3 arranged one behind the other, which are in contact contact with the end support 20 and with the abutment means 6, so that these damping elements 3 are enclosed between the abutment means 6 and the end support 20.
the support element 5, of which four are provided in the illustrated embodiment, supports the abutment means 6 against the ground.
the support elements 5 are rotatably bendable by means of a bendable attachment 8 about a horizontal axis 7.
Fig. 2 shows a schematic representation of a detail of in Fig.1 reproduced embodiment of the collecting device according to the invention. As in Fig. 1 indicated, three damping elements 3 are shown in front of the investment means 6, wherein the total number of in the Fig. 1 and 2 shown embodiment, thirteen damping elements 3 in the dynamic collecting device 2.
the support element 5 is in the in Fig. 2 illustrated embodiment, a substantially straight Abstützbalken 51 which is fixed by means of the bendable attachment 8 at the bottom.
the bendable attachment 8 consists in the illustrated embodiment of a metal mounting bracket 81 with a mounting flange 82 which rests on the floor.
the abutment means 6, which in the illustrated embodiment is essentially a suitably shaped abutment plate, is rotatably supported on the support bar 51.
Fig. 2 is shown in dashed lines the position of the Abstützbalkens 51 ', which he occupies when after a heavy impact, the damping elements 3 are compressed and moved over a predetermined distance, which is provided between the rest position and the Auffangwolf.
the contact plate of the attachment means rotates in its holder about the axis 7 and is raised by the height of the secant of the angle of rotation.
the mounting bracket 81 bends and thus provides a working resistance, which causes an energy consumption.
the damping characteristic of the dynamic collecting device 2 can be designed such that the resistance of the mounting bracket 81 is so large that first the damping elements 3 are deformed before the bending of the mounting bracket 81 so long due to the large torque on the support bar 51 in a vertical position until it comes to a stopper 14 to the plant.
the damping characteristic may be designed so that first the displacement of the damping elements 3 and thus the rotation of the beam 51 in the position of the beam 51 'against the resistance of the mounting bracket 81 takes place and only after installation of the beam 51 in the position 51 'on the stopper 14, the deformation work on the damping elements 3 begins.
Fig. 3 shows a view corresponding to those in Fig. 2 a further embodiment.
the support element 5 is formed as an angled, substantially L-shaped Abstützbalken 52
the downwardly projecting leg 9 is held by means of the bendable metal mounting bracket 81 and at the free end of the other, horizontally protruding leg 10, the investment means 6 rotatably supports the damping elements 3.
the rotatable bendable attachment 8 has in this embodiment a particularly long mounting flange 82 which is fixed by means of bottom attachment means 13 on the ground.
the bottom attachment means 13 are designed as a breakage protection, which can break continuously progressively. This action occurs when the angular support beam 52 is rotated from position A due to impact into position B against the resistance of the fixture 8.
Fig. 4 shows a plan view of a particular arrangement of the damper 3 of the dynamic collecting device 2.
the damping elements 3 are arranged in five substantially in the direction of travel F extending rows, each row of the adjacent a distance 5 'has.
the distance 5 ' is substantially the thickness of the L-shaped Abstweilbalkens 52, so that the displacement of the damping elements 3 is free and is not blocked by the L-shaped Abstützbalken, as would be the case if adjacent rows in contact with each other and no clearance for the L-shaped braces 52 remained.
an apron is provided, which encloses the arrangement of the damping elements 3 in the collecting device 2, in order to prevent in a lateral impact, a knocking out of damping elements 3.
Fig. 5 shows a next embodiment, in which the abutment means 6 in the impact direction with at least one damping means 3 'cooperates, after all the preceding damping elements 3 are consumed.
a compressible dynamic collecting device 2 shown is secured by a device for preventing the structure from being singulated upon impact.
This device consists in the illustrated embodiment of a plurality of wire ropes 16, which are passed through openings in the damping elements 3 and other components such as in the support means 5 and in the event of destruction of the respective attachments of these parts prevent flying away of the components.
the invention is not limited to the illustrated and described embodiments, but also includes those provided by a combination of the various embodiments. Thus, it may be provided, for example, that the damping means 3 'behind the abutment means 6 both in a rectilinear obliquely arranged support means 5 as well as in the embodiment with an angled support member 5, namely an L-shaped support bar 52, are used.
the geometric shape of the damping elements 3, instead of being round, has a different shape.
the number of reproduced damping elements 3 is variable and not limited to the illustrated series arrangement. For example, it is also possible to use horizontal damping elements 3 or damping elements 3 of a different design, or the necessary work of deformation can be controlled by filling with a filling material, be it plastic granulate or sand, to a specific damping behavior.
