Abstract
Abstract A support member such as a skid is attached to a frame of a machine or similar apparatus by means of a bolt extending through an aperture in the support member. The head of the bolt is engaged by a bifurcated retention means, the outer dimension of which is greater than the corresponding aperture dimension. The skid is readily released from the supported machine with minimum time and effort by manually applying sufficient force to the support member in a direction generally away from the frame, thereby deforming and reducing the outer dimension of the retention means and allowing it and the bolt head to pass through the aperture in the support member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
A quick-release means for temporarily attaching the support member to apparatus to facilitate safe transport thereof comprising: a bolt-like leg member connected to the underside of the apparatus and protruding therefrom, said bolt-like leg member having a shank and a widened foot portion integral to the outer end of the shank, a support member disposed beneath the apparatus and having an aperture therethrough in alignment with the leg member such that the shank thereof protrudes through the aperture and the foot portion projects below the aperture, a deformable plate disposed between the support member and the foot portion and acting to hold the support member against the underside of the apparatus, the aperture being an enlarged opening and the plate being shaped as a plane figure having generally opposite edge portions thereof extending across the aperture and having corner portions extending outwardly past the edge of the aperture in contact with the support member, and the plate being adapted to deform and move entirely through the aperture with the foot Portion in response to a force applied to the support member to free it entirely from its engagement to the apparatus such that damage and deformation is restricted solely to the plate.
Claim 2
Dependent Claim
202 words
A quick-release means for temporarily attaching the support member to apparatus to facilitate safe transport thereof comprising: a bolt-like leg member connected to the underside of the apparatus and protruding therefrom, said bolt-like leg member having a shank and a widened foot portion integral to the outer end of the shank, a support member disposed beneath the apparatus and having an aperture therethrough in alignment with the leg member such that the shank thereof protrudes through the aperture and the foot portion projects below the aperture, a deformable plate disposed between the support member and the foot portion and acting to hold the support member against the underside of the apparatus, the aperture being an enlarged opening and the plate being shaped as a plane figure having generally opposite edge portions thereof extending across the aperture and having corner portions extending outwardly past the edge of the aperture in contact with the support member, and the plate being adapted to deform and move entirely through the aperture with the foot Portion in response to a force applied to the support member to free it entirely from its engagement to the apparatus such that damage and deformation is restricted solely to the plate.
Claim 3
Dependent Claim
24 words
The invention of claim 1 wherein the plate is adapted to fall free from the leg member after the plate moves through the aperture.
Claim 4
Dependent Claim
16 words
The invention of claim 1 wherein the leg member is releasably threadably attached to the apparatus.
Claim 5
Dependent Claim
50 words
The invention of claim 1 wherein the plate has a slotted opening extending from its outer edge inward toward its center, and the dimension across the opening adjacent the center of the plate is less than the width of the foot portion and greater than the thickness of the shank.
Claim 6
Dependent Claim
97 words
The invention of claim 1 wherein the plate has an opening therethrough, the shank extends through the plate opening and the foot portion of the leg member serves as a shoulder contacting the plate surface adjacent the opening, the plate is adapted to reside against the support member and normally hold its shape and thereby prevent the support member from moving away from the apparatus, and the plate being further adapted to deform in response to manual force directed against the support member whereby the plate assumes a new shape that will slip entirely through the aperture.
Claim 7
Dependent Claim
37 words
The invention of claim 1 wherein the support member has a recess about the aperture enabling the plate and the foot portion of the leg member to be insert past the outside surface of the support member.
