Definitions
- ABSTRACT A covering for objects that are exposed to impacts, such as road and bridge parapets, guiding curbs, motorcar bumpers, central reserve guard rails for expressways etc.
- the covering comprises a jacket of resilient material with a hollow space therein in which a damping material, preferably sand, is enclosed.
- the hollow space has a volume greater than the damping material, whereby the latter can expand when the covering is exposed to an impact.
- the covering 12 can have onits upper side a particular casing 23 which can eitherbe formed inonepiece with the envelope 13 or be an individual part secured thereto.
- the casing 23 accommodates lamps 24 and conductors 25 which may also be placed in a tubular conduit at the point designated 26 in" the interior of the envelope 13.
- the present invention has for its object to provide a shockabsorbing structure of this type, which is realized by means of a covering for the parapet, guard,.rail etc.-,' said covering comprising a jacket or envelope of suitable resilient material, such as polyethylene, and a damping material, preferably sand,
- FIG. 1 is a vertical section of a shock-absorbing covering according to the invention.
- FIG. 2 is a horizontal section of the covering in FlG. l.
- the illustrated shock-absorbing covering according to the invention is mounted on a guard rail of the type' which is placed between the roadways of an expressway.
- the guard rail comprises vertical uprights l0, preferablyof-the profile shown in FIG. 2, which are secured in the ground.
- a U-shaped beam 11 is secured to'the upper ends of the uprights 10 to extend between them.
- the beam 11 is connected to the uprights preferably by screws.
- a shock-absorbing covering generally designated 12 is placed on the guard rail which is composed of the parts 10 and 11.
- the covering 12 is a jacket or envelope ll! of polyethylene or some othcr suitable plastics material.
- the envelope l3 is approximately square and has a recess 14 which opens at the underside of the envelope and has a depth exceeding half the height of the envelope, and a width corresponding to that of the parts 10 and 11.
- the envelope 13 has bumper ribs 15.
- the envelope contains a filling of sand 16.
- the sand'l6 does not fill out the envelope l3 entirely, but leaves an expansion space 17 above the sand.
- the envelope 13 is preferably-manufactured by injection molding in lengths of about 5 meters. The sand is filled into the envelope through holes therein, which are then closed by welding.
- the covering 12 is mounted on the rail 10, 11 in the manner illustrated in FIG. 1.
- a beam 18 is provided for additionally supporting the envelope on the rail. It is connected to the uprights 10 in the same manner as the beam 11 and has two channels 19, 20 in which to receive flanges 21 and 22, respectively, projecting from the envelope 13 on either side of the recess 14.
- the covering can be secured to the rail 10, 11 in any desired manner whatever. it is preferably mounted by clamping action on the rail or is shrunk thereonto, whereby a certain mobility is attained relative to the rail. It is also possible to secure the covering by adhesive bonding or by screwing. It is essential that the covering is simple to mount at the site and that damaged parts are easily exchangeable. I
- the height of the mil with the covering mounted in position thereon is preferably about i meter, and the total width of the covering may be of the size of e.g. 0.5 meter.
- the illustrated embodiment of the covering is meant to be placed. on a rail between the roadways of an expressway, but it is self-explanatory that the covering can readily be adapted for. mounting on bridge parapets'and like guard structures.
- said envelope can have its top provided with a hook-shaped portion with or without sand filling, which is placed about the upper beam of the bridge parapet, while the envelope. at the bottom has a flange corresponding to flange 22 and received in a supporting rail in the same manner as said flange '22.
- a covering for a bridge parapet can also suitably have a flange'22'both at the top and atthe bottom and be secured by means of two spaced U- shaped means which are secured to the bridge parapet with facing openings.
- the covering mayof course also be placed on vehicles, particularly onthe bumpers thereof or in such a way as to fonn a complete vehicle front.
- a road guard rail structure composed of longitudinal beams parallel to the roadway and vertical uprights supporting said beams, ane'nvelope, a hollow space in said envelope, a recess in one side of the envelope for receiving the beams, a
- damping material and flanges projecting on either side of the recess in the envelope, said damping material being disposed in said hollow space and having a volume smaller than said hollow space, said recess having a depth exceeding half the height of the envelope, and said flanges on either side of the recess being connected with the road guard rail structure.
- a road guard rail structure composed of longitudinal beams parallel to the roadway and vertical uprights supporting said beams, an envelope, a hollow space in said envelope, a recess in one side of the envelope for receiving the beams, a damping material, and flanges projecting on either side of the recess in the envelope, a casing on the envelope, lighting means on the casing, and means for supplying electric power to the lighting means to cause them to be lit, said damping material being disposed in the hollow space and having a volume smaller than said hollow space, said recess having a depth exceeding half the height of the envelope, and receiving means attached to and extending between the uprights and adapted to receive said flanges.
