| 摘要 | A latch mechanism for latching either of two types of containers to a supporting structure. Movement of the mechanism between the unlatched position and the latched position latches to the supporting structure whichever type of container has been placed thereon. The mechanism includes a vertically disposed pivotal member which carries a latch head portion at one end thereof for latching one type of container. Also included in the mechanism is a detent which is arranged to project through an opening in a portion of the supporting structure and into a mating opening in another type of container to latch it in position. | ||||||
| 权利要求 | 1. A latch mechanism comprising a frame structure, a vertically disposed pivotal member carried on the frame structure, a latch portion at one end of said pivoted member, means for pivoting the said pivotal member between an unlatched position and a latched position comprising an operating member and slot in the said frame structure through which the said operating member moves, the said frame structure having an opening therethrough separate from the said slot, and a detent carried on the said operating member which extends through the said opening in the latched position. 2. A latch mechanism as specified in claim 1 in which additional means are provided for releasably holding the mechanism rigidly in the unlatched position. 3. A latch mechanism as specified in claim 1 in which means are provided for releasably holding the said latch mechanism in the latched position. 4. A latch mechanism comprising a frame structure having top and bottom walls, an end wall and a sidewall, the said top and bottom walls having vertically aligned openings therein, a vertically disposed pintle member carried by the said frame structure and extending through the said openings, a latch head portion at the top end of said pintle member, the said pintle member having a horizontally disposed opening therethrough, a rod extending through the said opening and arranged for pivoting the said pintle member between an unlatched position and a latched position, the said side and end walls having slot portions through which the said rod member passes as it moves between unlatched and latched positions, a vertically projecting portion on the said frame structure having an opening therethrough separate from the said slot portions, and a detent carried by the said rod which extends through the said last mentioned opening in the latched position. 5. A latch mechanism as specified in claim 4 in which the said rod has secured thereto a stop member which abuts the end of the frame structure in the unlatched position and the side of the frame structure in the latched position. 6. A latch mechanism as specified in claim 5 in which the said rod has associated therewith a spring which urges the said stop member toward the said frame structure. 7. A latch mechanism as specified in claim 5 in which the said stop member has a guide portion thereon which projects upwardly above the frame structure in the unlatched position. 8. A latch mechanism as specified in claim 5 in which the said stop member has a handle portion secured thereto. 9. A latch mechanism as specified in claim 7 in which the inner end of the said rod member has means thereon for releasably connecting the rod to the said frame structure. 10. A latch mechanism as specified in claim 9 in which the said releasable mechanism comprises a transverse pin through the rod and a key slot in a brace member of the said frame structure through which the said pin may pass. 11. A latch mechanism as specified in claim 4 in which the said vertically projecting portion on the frame structure has a guide portion thereon which projects upwardly above the frame structure. |
