Abstract
Abstract An attachment apparatus designed to facilitate the quick connection and release of movable objects relative to a fixed surface. The apparatus provides a fixed base shoe member which is firmly secured to a stationary surface. The shoe member is constructed from a spherical segment having a channeled groove extending therethrough, inwardly extending flanges are provided in conjunction with the channel groove for holding a movable foot member within the groove. The foot member is secured to a coupling apparatus which carries a retainer means for locking the foot member in place directly beneath the inwardly extending flanges of the shoe member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
Quick disconnect device for attachment of objects to a fixed surface relative thereto comprising a spherical segment shoe member having a flat base surface securable to the fixed surface, a channel groove transversely extending completely through the segment parallel to the base surface and having the opposite ends open, inwardly extending flange members making up a portion the outer surface of the spherical segment and forming a narrow slot between said flanges, enlarged openings in the flanges at each end of the channel groove in communication with the respective open ends thereof; a coupling means attachable to the spherical segment and comprising a foot member slidable through said open ends into the channel groove, attachment means secured to the foot member for the attachment of movable objects, retainer means carried by the attachment means and engageable with the shoe member to selectively lock the foot member within the channel groove.
Claim 2
Dependent Claim
150 words
Quick disconnect device for attachment of objects to a fixed surface relative thereto comprising a spherical segment shoe member having a flat base surface securable to the fixed surface, a channel groove transversely extending completely through the segment parallel to the base surface and having the opposite ends open, inwardly extending flange members making up a portion the outer surface of the spherical segment and forming a narrow slot between said flanges, enlarged openings in the flanges at each end of the channel groove in communication with the respective open ends thereof; a coupling means attachable to the spherical segment and comprising a foot member slidable through said open ends into the channel groove, attachment means secured to the foot member for the attachment of movable objects, retainer means carried by the attachment means and engageable with the shoe member to selectively lock the foot member within the channel groove.
Claim 3
Dependent Claim
99 words
A quick disconnect device as set forth in claim 1 wherein the foot member comprises an elongated flat bar slidable within the channel groove and being wider than the narrow slot between the flanges of the shoe member, and wherein the attachment means comprises an elongated narrow bar secured to one surface of the flat bar and extendable between the flanges when the foot member is disposed within the channel groove, and wherein the retainer means comprises a threaded bore through the narrow bar and flat bar and a set screw rotatable therein and engageable with the shoe member.
Claim 4
Dependent Claim
41 words
A quick disconnect device as set forth in claim 2 wherein the attachment means narrow bar and the foot member flat bar are of integral construction forming a substantial T-shape cross-section and the outer portion thereof extends beyond the shoe member.
Claim 5
Dependent Claim
54 words
A quick disconnect device as set forth in claim 3 wherein a fishing rod holder comprising a tube having transverse slot adjacent one end thereof for receiving the outer portion of the attachment means therethrough, the end of the attachment means being attached to the other inside surface of the tube opposite the slot.
Claim 6
Dependent Claim
66 words
A quick disconnect device as set forth in claim 4 wherein said outer portion of the attachment means is a bar having a 45° bend, a shoulder means spaced from the end thereof, a fishing rod holder comprising an elongated tube member having a pair of aligned slots for receiving the outer portion end of the attachment means therethrough one slot being engageable with the shoulder.
Claim 7
Dependent Claim
210 words
A quick disconnect device as set forth in claim 1 wherein the foot member comprises a flat plate slidable within the channel groove and having width greater than the narrow slot between the flanges, the attachment means comprising an elongated pin secured at one end to one surface of the plate, the pin diameter being less than the width of the narrow slot and extending outward therethrough when the plate is centered within the channel groove, coupling device secured to the outer portion of the pin for attachment to movable objects, and wherein the retainer means comprises a bracket which in turn comprises a cross member and parallel leg members at opposite ends thereof which form a U-shaped cross-section, the cross member being slidably disposed on the pin, the leg members being directed toward the plate end of the pin, the inside surfaces of the leg members having cross-sectional shape to conform to the shape of the edge of the plate for receiving said plate therebetween, the leg members being insertable into the opposite enlarged openings in the flanges and engageable with the shoe member groove, and a helical compression spring surrounding the pin between the bracket and the coupling device for urging the bracket toward the plate foot member.
Claim 8
Dependent Claim
43 words
A quick disconnect device as set forth in claim 6 wherein the foot member plate is round in shape and rotatable within the channel groove and the coupling device is a tie-down ring pivotally secured to the outer end of the attachment pin.
Claim 9
Dependent Claim
31 words
A quick disconnect device as set forth in claim 6 wherein the foot member plate is rectangular in shape, the diagonal dimension being greater than the width of the channel groove.
Claim 10
Dependent Claim
52 words
A quick disconnect device as set forth in claim 8 wherein the coupling device comprises a sleeve member fixed to the outer end of the pin, an elongated rod being attached to the outer end of the sleeve member said longitudinal rod having a 360° loop therein to form a support eyelet.
