Releasable automatic fastener for a truck stake and like

Claim 2

For a combination of a stake with an elongated exposed section and, as a pertinent member, a relatively shorter end section, and, as another pertinent member, a receptacle for said end section, an automatic fastener for the stake-end-section in the receptacle which fastener requires a substantially instantaneous double action in two different directions for removing the automatically fastened stake from the receptacle and comprises a sidewise exposed edge in one of said two pertinent members, a sidewise protruding clutching means secured with the other of said two pertinent members for engaging against said edge when therebelow and is pushed sidewise thereagainst, an outwardly resilient normally sidewise protruding compressible means secured with one of said two pertinent members for being resiliently compressed when within the receptacle for pushing said clutching means sidewise for automatic engagement against said edge when said end section is within said receptacle and the clutching means is below said edge while the compressible means remains substantially compressed; the stake being removable from the receptacle by pushing the exposed section of the stake in the direction of the location of the clutching means with a force sufficient to compress further the compressible means to the extent where the clutching means becomes released, and, thereupon, pulling the stake from the receptacle without reducing the eXtent of the push which releases the clutching means.

Claim 6

For a combination of a truck-stake with an elongated exposed section, and a relatively shorter end section with a bottom having a sidewise exposed recess of a predetermined depth extended upwardly to the end section, and a suitably shaped and sized stake receptacle with side walls, and a lower edge from its sidewall exposed inwardly, and a means for restricting the extent of the stake insertion into the receptacle for keeping the exposed edge of the receptacle below and at a predetermined distance from the stake bottom when the stake-end-section is substantially fully inserted into the receptacle, comprising an automatic fastener for the stake-end-section in the receptacle including a normally substantially flat pad of a thickness slightly exceeding the predetermined recess depth in the bottom section of the stake and the predetermined distance from the stake bottom to the receptacle exposed edge, and of a resilient and compressible material, and secured flat against the stake bottom with a portion thereof protruding sidewise from the exposed recess and beyond the stake-end-section and compressible into said recess and resilient against the adjacent receptacle--inner-side-wall when the end section is inserted into the receptacle, and is adapted for exercising a continuous sidewise pressure against the end section towards an opposite receptacle--inner-wall with the exposed edge when the end section is in the receptacle; a substantially flat rigid plate secured to the stake bottom under and substantially flat against said pad, and having a portion thereof protruding sidewise slightly beyond the side of the end section which is opposite to the side having the recess, for fastening itself automatically against the exposed edge when brought immediately therebelow by the thickness of the pad when the end section is substantially fully inserted into the receptacle, and while being pressed sidewise thereagainst by the resiliency of the compressed portion of the pad.

Claim 7

The invention according to claim 3 and a means for fastening the rigid plate to the bottom of the stake under the flat pad and comprising a bolt member upwardly protruding from the upper face side of the plate, a hole through the pad for said bolt member passage therethrough, a receptacle in the bottom section of the stake for the loose end section of said bolt member for fastening the latter to the bottom section of the stake via said bolt member-receptacle.

Claim 8

For a combination of a truck-stake and a stake receptacle, an automatic fastener for the stake in the receptacle and comprising a notch with outwardly exposed edge in the side wall of the stake-end-section, a compressible and resilient member secured to the inner wall of the receptacle, a clutching member secured to and protruding inwardly from the opposite inner wall of the receptacle substantially opposite the compressible member and adapted to engage in the notch against its exposed edge when the notch is brought thereagainst and the compressible and resilient member is compressed by the stake-end-section to exercise pressure thereagainst towards the clutching member when the end-section of the stake is inserted into the receptacle.

Claim 9

For a combination of a truck-stake and a stake receptacle, an automatic fastener for the stake in the receptacle and comprising a notch with outwardly exposed edge in the side wall of the stake-end-section, a compressible and resilient member secured to the inner wall of the receptacle, a clutching member secured to and protruding inwardly from the opposite inner wall of the receptacle substantially opposite the compressible member and adapted to engage in the notch against its exposed edge when the notch is brought thereagainst and the compressible and resilient member is compressed by the stake-end-section to exercise pressure thereagainst towards the clutching member when the end-section of the stake is inserted into the receptacle.

Claim 10

For a combination of a truck-stake and stake-receptacle, an automatic fastener for the stake in the receptacle and comprising a notch with outwardly exposed edge iN the side wall of the stake-end-section, a clutching member secured to and protruding inwardly from the inner wall of the receptacle and adapted to engage the notch and against its exposed edge when the notch is brought and pressed thereagainst, a compressible and resilient member secured to the stake-end-section and protruding from its side which is opposite to the side having the notch, said compressible and resilient member adapted to press the notch towards and against the clutching member when the end section of the stake is inserted into the receptacle and the resilient member is thereby compressed against the inner wall of the receptacle which wall is opposite to its wall having the clutching member.
