Abstract
Abstract A dock clamp employed in combination with a dock support structure that supports a dock section at an adjusted height by means of post members that are slidable within corresponding sleeve members attached to the dock section, the dock clamp serving to provide a fixed frictional coupling between a pair of corresponding post and sleeve members. The dock clamp includes a pair of rigid pieces each having an open end and a pronged end with a tapered configuration that is wedged between corresponding post and sleeve members at opposing ends and at one side of the sleeve member for applying a radial force in a direction that drives said post and sleeve members together at the side opposite to said one side in response to an applied axial force. The dock clamp further includes fastener means for applying an axial force by forcing facing open ends of said pair of rigid pieces toward one another.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
193 words
In combination with a dock support structure for supporting a dock section at an adjusted height which includes at least a pair of post members slidable in the axial direction within corresponding sleeve members attached to either side of said dock section, the outer wall of said post members being in close proximity with the inner wall of said sleeve members when said members are centered on one another, a dock clamp for securing said post members to corresponding sleeve members at said adjusted height, comprising: (a) prong means for insertion at opposing ends and at one side of one of said sleeve members between the inner wall of said sleeve member and the outer wall of a corresponding post member, said prong means being constructed so as to apply a radial force to said inner and outer walls in a direction that drives said walls together at the side opposite to said one side in response to an applied axial force, and (b) further means for applying an axial force to said prong means, whereby the application of sufficient axial force provides a fixed frictional coupling between corresponding post and sleeve members.
Claim 2
Dependent Claim
193 words
In combination with a dock support structure for supporting a dock section at an adjusted height which includes at least a pair of post members slidable in the axial direction within corresponding sleeve members attached to either side of said dock section, the outer wall of said post members being in close proximity with the inner wall of said sleeve members when said members are centered on one another, a dock clamp for securing said post members to corresponding sleeve members at said adjusted height, comprising: (a) prong means for insertion at opposing ends and at one side of one of said sleeve members between the inner wall of said sleeve member and the outer wall of a corresponding post member, said prong means being constructed so as to apply a radial force to said inner and outer walls in a direction that drives said walls together at the side opposite to said one side in response to an applied axial force, and (b) further means for applying an axial force to said prong means, whereby the application of sufficient axial force provides a fixed frictional coupling between corresponding post and sleeve members.
Claim 3
Dependent Claim
54 words
A dock clamp as in claim 1 wherein said prong means comprises a pair of rigid pieces each including an open end and a pronged end having a tapered configuration which allows said pronged end to be wedged between said inner and outer walls at each of said opposing ends of said sleeve member.
Claim 4
Dependent Claim
28 words
A dock clamp as in claim 2 wherein said further means comprises fastener means for pulling facing open ends of said pair of rigid pieces toward one another.
Claim 5
Dependent Claim
52 words
A dock clamp as in claim 3 wherein the open end of each of said pair of rigid pieces is provided with an aperture and said fastener means comprises a bolt member that passes through each of said apertures and is tightened down on said open ends by a screw thread arrangement.
Claim 6
Dependent Claim
21 words
A dock clamp as in claim 4 wherein said rigid pieces and bolt member are composed of a rust resistant material.
Claim 7
Dependent Claim
180 words
A dock clamp assembly for supporting a dock section at an adjusted height, comprising: (a) at least one pair of sleeve members attached to either side of said dock section for receiving corresponding post members that are slidable in the axial direction within said sleeve members, the outer wall of said post members being in close proximity with the inner wall of said sleeve members when said members are centered on one another, (b) prong means for insertion at opposing ends and at one side of one of said sleeve members between the inner wall of said sleeve member and the outer wall of a corresponding post member, said prong means being constructed so as to apply a radial force to said inner and outer walls in a direction that drives said walls together at the side opposite to said one side in response to an applied axial force, and (c) further means for applying an axial force to said prong means, whereby the application of sufficient axial force provides a fixed frictional coupling between corresponding post and sleeve members.
Claim 8
Dependent Claim
180 words
A dock clamp assembly for supporting a dock section at an adjusted height, comprising: (a) at least one pair of sleeve members attached to either side of said dock section for receiving corresponding post members that are slidable in the axial direction within said sleeve members, the outer wall of said post members being in close proximity with the inner wall of said sleeve members when said members are centered on one another, (b) prong means for insertion at opposing ends and at one side of one of said sleeve members between the inner wall of said sleeve member and the outer wall of a corresponding post member, said prong means being constructed so as to apply a radial force to said inner and outer walls in a direction that drives said walls together at the side opposite to said one side in response to an applied axial force, and (c) further means for applying an axial force to said prong means, whereby the application of sufficient axial force provides a fixed frictional coupling between corresponding post and sleeve members.
Claim 9
Dependent Claim
55 words
A dock clamp assembly as in claim 6 wherein said prong means comprises a pair of rigid pieces each including an open end and a pronged end having a tapered configuration which allows said pronged end to be wedged between said inner and outer walls at each of said opposing ends of said sleeve member.
Claim 10
Dependent Claim
29 words
A dock clamp assembly as in claim 7 wherein said further means comprises fastener means for pulling facing open ends of said pair of rigid pieces toward one another.
Claim 11
Dependent Claim
53 words
A dock clamp assembly as in claim 8 wherein the open end of each of said pair of rigid pieces is provided with an aperture and said fastener means comprises a bolt member that passes through each of said apertures and is tightened down on said open ends by a screw thread arrangement.
Claim 12
Dependent Claim
22 words
A dock clamp assembly as in claim 9 wherein said rigid pieces and bolt member are composed of a rust resistant material.
