However, the rear wall 48 is cut assembly carried at one end of a cross bar showaway and terminates in a shoulder 50, as best ing a p rt on of t e Supporting Wa in S seen in Figure 2, on which the reduced portion 32 Figure 2 is a side elevation partly in section of of the head is supported. A plate 52 is connected the head supporting structure. to the upper edges of the side walls M and 46 and Figure 3 is a section on the line 3-3, Figure 2. 5o overlies the intermediate portion of the shank 22 Figure 4 is a diagrammatic view illustrating a of the head at. The housing structure is commodified arrangement of latch release lever conpleted by an end plate as which may be welded struction. or otherwise secured to the forward edges of the In the figures the cross bar is illustrated genside walls M and 56 and the forward edge of the erally at Ill and as disclosed in my prior Patent plate 52, as well as the adjacent end surfaces of the cross bar. The end plate 54 is provided with a vertical slot 56 in which the forward end of the shank portion 22 of the head is movable.

With the parts in the position illustrated in Figure 2, it will be observed that weight applied to the cross bar I is supported by the hook portions 26 of the head, thereby tending to rock the head in a counterclockwise direction about the axis established by shoulder 50. Such counterclockwise rotation however is prevented by engagement between the shank 22 and the plate 52 which engages the upper surface of the shank of the head outwardly of the shoulder 50. It will further be observed that the shoulder 50 of the rear wall 48 constitutes a fixed pivot support about which the head 26 may rock. Thus, in order to withdraw the head 20 from the openings 3G in the wall W the end of the cross bar structure is raised and the head 20 will thereupon rotate relative to the end of the cross bar in a clockwise direction, thus permitting withdrawal of the hooks 26 from the openings 30. When the head 28 is withdrawn from the opening 30 it is retained in assembly with the cross bar by engagement between the shoulder 34 and the rear wall is and also simultaneous engagement between the shoulder and the inner end of the top plate 52.

It will also be observed that in the assembled relationship illustrated in Figure 2, the head is longitudinally movable with respect to the cross bar and will therefore accommodate relative approach and separation between a pair of opposed walls W.

In order to prevent inadvertent separation between the cross bars and the walls W, latch means are provided associated with the head which prevent movement of the head relative to the cross bar in the direction which is required to effect removal of the head from the openings in the wall. This means comprises a pair of latch members 6?! and 62. The latch members are pivoted to a pivot pin 64 carried by the front plate and have associated with the pivot pin 64 a spring 86 biasing the latch members to the latching position. The web l2 of the cross bar is provided with slots 68 through which the latch members extend providing for limited movement thereof, this movement however being sufficient to permit withdrawal of the hook portions 10 of the latch members from beneath the shanks 22 of the head 20.

In order to facilitate unlatching of the head to permit its withdrawal from the openings 30 in the wall W, special means are provided. This means is best illustrated in Figure 3 and comprises a lever 12 carried by a pivot pin 14 on one of the latch members, herein illustrated as the latch member 52. The other latch member is provided with a projection 15 which is coplanar with the lever 12. The lever 12 has formed therein a recess 16 which receives the projection 15. When the operator wishes to release a cross bar from its interlocked position from a wall W, he first supports the weight of the cross bar so as to release parts of the head and latch mechanism for movement. upon, he applies pressure to the lever 12. Pressure applied. to the lever 12 tends to rock the latch member 58 in a clockwise direction and the reaction produces forces tending to rock the latch 82 in a counterclockwise direction. As a result, single application of pressure to the lever 12 will swing both latch members 60 and 62 outwardly so as to withdraw the hook portions i0 thereof from beneath the shank 22 of the head 20. Thereupon the cross bar may be raised and the head 20 may rock relative thereto in a clockwise direction withdrawing the hooks 26 from the openings 30.

Referring now to Figure 4 there is illustrated another embodiment of the present invention in which the latch levers 60 and 62 are as before described, but the latch release lever, herein designated 12a, is provided with a tooth adapted to be received within a recess 82. Downward pressure applied to the lever 12a initially rocks the latch member 60 in a clockwise direction, the tooth 80 and recess 82 cooperating in the manner of gear teeth and tooth spaces during such movement of the latch member 60. Movement of the latch member 50 is arrested by engagement between the latch member and the side of the slot 68 and continued application of pressure to the lever 12a thereupon results in rocking movement of the latch member 62 to its release position.

The drawings and the foregoing specification constitute a description of the improved cargo brace structure in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
