Abstract: 1316091 Pallets TILGATE PALLETS Ltd 17 June 1970 [18 March 1969] 14113/69 Heading B8H [Also in Division E2] A combination of a panel 10, a base 11 and means for detachably mounting the panel on the base in a position with an edge of the panel extending along and close to an edge of the base, which means comprising a manually-operable bolt mechanism including a bolt 45 arranged to fasten the panel releasably to the base at a region adjacent to the said edges, and retaining means acting between the panel and the base at a region spaced along the edges from the bolt mechanism, the retaining means co-operating with the bolt mechanism to hold the panel in its mounted position on the base, and the retaining means comprising a detent member 30 and a co-operating socket 20, the detent member being rigidly secured to and protruding from one of the edges and the profile of the detent member including a detent portion 31 which is inclined at an acute angle to the length of that edge, and the socket being provided on the other edge at a corresponding position along the length thereof and having a fixed abutment 25 in its interior at one side thereof, and the detent member being adapted to enter the socket endwise to one side of the abutment to allow the panel to assume its mounted position on the base with the bolt mechanism disengaged, and the detent portion of the detent member profile engaging behind the abutment to prevent the withdrawal of the detent member from the socket when the bolt mechanism is engaged between the panel and the base. As shown the socket 20 is carried by the base and the detent member by the panel and the abutment is a bar 25 with the portion 31 being an inclined edge of the detent member. The other edge 32 of the member 30 is parallel to the edge 31. The member 30 is provided near the left hand end of the panel and the socket is correspondingly provided near the left hand end of the base; the bolt mechanism is near the other ends of the panel and base; it includes a keeper plate 40 which is engageable in a second socket 21. The plate 40 has a slot extending from its lower edge which has a narrow entrance portion which terminates in an enlarged end portion 43; the socket carries the bolt 45 which is spring loaded and which extends through aligned apertures in plates 22 and 23 of the socket and in a guide bracket 46 welded to the base, the bolt having a small diameter outer end portion 49 which is an easy fit in the end portion of the slot and an enlarged inner portion 50 which is too large to enter the entrance portion of the slot but is smaller than the enlarged end portion 43 so that it can enter the latter; the small diameter of portion 49 protrudes outwardly beyond the front plate 23 of the socket to act as a push button and the outward movement of the bolt is permitted by a flange 47, the spring acting between the flange and the guide bracket 46 the bolt must be depressed to enable the plate 40 to enter the socket and when it is fully entered the bolt is released so that the portion 50 enters the enlarged end portion of the socket.
