Abstract A truck described herein comprises a movable loading table, energy absorber means and energy transmission means. The loading table is mounted on a body frame of the truck in such manner that it may move in the forward direction along said body frame when an impact force larger than a predetermined value is applied to a vehicle body of said truck. The energy absorber means is interposed between said body frame and said loading table for absorbing kinetic energy possessed by said loading table. The energy transmission means has its front end connected to a front bumper and is provided with an end portion located behind the cabin of the truck so as to be positioned in the path of said moving loading table. The energy transmission means is mounted on the body frame of said truck in such manner that it may move in the forward or backward direction along said frame body when an impact force larger than a predetermined value is applied thereto. The energy transmission means is mounted on the frame body by a bolt fixedly secured to either said energy transmission means or said body frame and extending through a center of a slot formed in forward and backward directions in the other of said transmission means or body frame to couple both of said members together. Upon movement of said energy transmission means in the forward or backward direction, said bolt is adapted to expand the slot, resulting in its plastic deformation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A truck comprising: a body frame; a cab fixed to said frame; a loading table positioned on the frame rearwardly of the cab; energy absorber means operatively related to said frame and the table, said energy absorber means including means for joining said table to the frame, said joining means being responsive to a force on said table in excess of a predetermined value for permitting movement of the table with respect to the frame forwardly towards said cab whereby during said movement kinetic energy of said moving table is absorbed by the energy absorber means; and energy transmission means joined by connecting means to said frame forwardly of the table, said energy transmission means including a front portion extending forwardly of the cab and a rear portion interposed between said cab and the table, said connecting means being responsive to impact on either of said front and rear portions in excess of a predetermined magnitude for permitting rearward and forward movement, respectively, of the energy transmission means with respect to the frame whereby kinetic energy developed by said impact is absorbed by the energy transmission means.
Claim 2
Dependent Claim
187 words
A truck comprising: a body frame; a cab fixed to said frame; a loading table positioned on the frame rearwardly of the cab; energy absorber means operatively related to said frame and the table, said energy absorber means including means for joining said table to the frame, said joining means being responsive to a force on said table in excess of a predetermined value for permitting movement of the table with respect to the frame forwardly towards said cab whereby during said movement kinetic energy of said moving table is absorbed by the energy absorber means; and energy transmission means joined by connecting means to said frame forwardly of the table, said energy transmission means including a front portion extending forwardly of the cab and a rear portion interposed between said cab and the table, said connecting means being responsive to impact on either of said front and rear portions in excess of a predetermined magnitude for permitting rearward and forward movement, respectively, of the energy transmission means with respect to the frame whereby kinetic energy developed by said impact is absorbed by the energy transmission means.
Claim 3
Dependent Claim
93 words
A truck according to claim 1, wherein one of said energy transmission means and said frame includes a slot having an enlarged central portion, said slot extending in a direction from the front portion towards the rear portion of the energy transmission means; and wherein said connecting means includes a bolt extending through the central portion of the slot to join the frame to the energy transmission means, said bolt being operative upon movement of the energy transmission means with respect to the frame to plastically deform the slot adjacent its central portion.
Claim 4
Dependent Claim
19 words
A truck according to claim 1, further comprising a bumper joined to said loading table and extending rearwardly thereof.
