An energy absorbing support for mailboxes and the like devices mounted alongside roadways where they are exposed to impact by vehicles has a post of generally reverse "C" shape with a depending upright leg secured in the socket of an anchor driven in the ground, an upwardly inclined generally horizontal lateral leg portion, an outwardly sloping generally vertical leg portion extending from the outer end of the lateral portion, and a reverse horizontal top leg portion overlying the lateral leg portion and having mountings thereon carrying mailboxes and the like. The depending leg portion is vertically adjustable in the socket of the ground anchor so that the upper end of the lateral leg portion and the lower end of the sloping vertical leg portion will be at a height above ground level within the range of the height of an automobile front bumper to receive initial impact of a vehicle crashing into the support. The socket anchor mounts the support parallel with the roadway and projecting towards oncoming traffic in the adjacent road lane so that any initial impact from a vehicle will bend and rotate the upright leg causing the support to tilt under the vehicle and prevent any portion thereof or any mailboxes carried thereby from crashing into the occupied area of the vehicle. The support can be extended by a complementary identically "C" shaped post secured to the depending upright leg and the free end of the top horizontal leg of the main post presenting a closed loop configuration lying in a flat plane. Mailboxes of the like are attached to the horizontal top legs of both posts. The posts can be composed of metal tubing with the upright leg portion having a weakened fracture zone just above the ground anchor. Mounting brackets carried by the horizontal leg of the post attach mailboxes and the like thereto and shear type attachments can be used to allow the boxes to leave the post upon severe impact.
A support for mailboxes and the like devices mounted alongside roadways which protects the occupants of a vehicle crashing into the support which comprises a post having a depending upright leg adapted to be anchored in the ground, a generally horizontal upright sloping leg extending laterally from the top of said upright leg, an outwardly sloping substantially vertical leg extending upwardly from the upper end of said lateral leg and a top horizontal leg extending rearwardly from the top of the sloping vertical leg overlying the lateral leg in spaced superimposed relation, and a ground anchor seating the lower end of the depending upright leg and securing the support in an upright position with the sloping legs parallel to the roadway and facing oncoming traffic on the roadway.
A post for mounting structures alongside roadways which crushes and bends upon impact by an oncoming vehicle to protect the occupants of the vehicle which comprises a generally reverse "C" shaped post having a depending upright lower leg, an upwardly sloping lateral leg extending from the top of the upright leg, an outwardly sloping vertical leg extending from the upper outer end of the lateral leg and a top horizontal leg extending rearwardly from the upper end of the vertical leg and overlying the lateral leg in spaced vertical relation, mountings on said top horizontal leg for structures to be carried by the post, and means for anchoring the lower leg in the ground at a depth to position the sloping legs parallel to the roadway facing oncoming traffic at a height to be engaged by vehicle bumpers of the oncoming traffic for controlling a bending of the post under the vehicle.
A support for mailboxes and the like which comprises a tubular structure having a depending vertical leg, diammetrically opposite upwardly sloped lateral legs extending from the upper end of the vertical leg, sloping vertical legs extending upwardly and outwardly from the outer ends of the lateral legs and a top horizontal leg extending from the tops of the sloping vertical legs and spanning the space therebetween in spaced relation above the lateral legs, mailboxes supported transversely on the top horizontal leg, a ground anchor having a socket receiving the lower end of the depending leg and wedge means in the socket locking the depending leg at a desired level to position the top horizontal leg for access to the mailboxes and to position the sloping vertical legs within the range of the height of an automobile bumper, and a weakened fracture zone in said depending leg at the top of the anchor socket.
A post for mounting structures alongside roadways which crushes and bends upon impact by an oncoming vehicle to protect the occupants of the vehicle which comprises a generally reverse "C" shaped post having a depending upright lower leg, an upwardly sloping lateral leg extending from the top of the upright leg, an outwardly sloping vertical leg extending from the upper outer end of the lateral leg and a top horizontal leg extending rearwardly from the upper end of the vertical leg and overlying the lateral leg in spaced vertical relation, a complimentary "C" shaped post connected to said lower leg and said top horizontal leg of the reverse "C" shaped post to provide a closed loop configuration with an extended top horizontal leg, and mountings on said top horizontal legs of the reverse "C" shaped post and the complimentary "C" shaped post for structures to be carried thereby.
