Abstract
Abstract Marine antenna mount permits ready horizontal laydown in fore or aft direction of antenna normally locked in vertical position by means of internal slidable block upon which antenna is secured. The block is provided with closed-end slots to receive pivot bosses carried in the base of the mount in the upper part of the passageway in which the block is slidable and normally locked by the weight of the antenna when vertical. Lifting of antenna to uppermost position permitted by the slots permits the antenna and block to be pivoted to a fore or aft laydown position. Transverse openings intermediate the closed ends of the slot permits the antenna and attached block, when shifted while in a laydown position, to be lifted off the pivot bosses and thereby readily removed for storage without dismounting the base. The base is mounted through a pair of cylindrical shims truncated in plane skew to end surfaces of the shims when arranged as a right cylinder; rotation of shims with respect to each other accommodates the base to the cant of the mounting surface of the boat (e.g., deck or cabin top).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
250 words
An antenna mount permitting ready shifting of an antenna between a relatively secure vertical position to a laydown position comprising a base member for mounting on a supporting surface, said base member having a wall portion defining a passageway serving as an upwardly opening internal socket when the base member is mounted on a relatively horizontal surface, transverse pivot means carried by said wall portion extending into said passageway adjacent the upper opening thereof, a block member longitudinally slotted to receive said pivot means and permit said block member to be slidably mounted in said passageway, means for connecting an antenna to said block member, said wall portion being provided with a first notch below the upper end thereof and located between the extension of said pivot means into said passageway, and the slot in said block extending toward the end of said block opposite said antenna connecting means a distance sufficient to permit said end to clear the wall portion of said base opposite said notch as said block is pivoted into said notch to permit an antenna connected thereto to be lowered from a relatively vertical position, said block including an opening from the exterior thereof into said slot therein, said opening being of sufficient width to permit said block to be pulled clear of said pivot means, whereby said block and an antenna connected thereto can be readily removed from said base member without removal of the latter from the supporting surface on which it is mounted.
Claim 2
Dependent Claim
250 words
An antenna mount permitting ready shifting of an antenna between a relatively secure vertical position to a laydown position comprising a base member for mounting on a supporting surface, said base member having a wall portion defining a passageway serving as an upwardly opening internal socket when the base member is mounted on a relatively horizontal surface, transverse pivot means carried by said wall portion extending into said passageway adjacent the upper opening thereof, a block member longitudinally slotted to receive said pivot means and permit said block member to be slidably mounted in said passageway, means for connecting an antenna to said block member, said wall portion being provided with a first notch below the upper end thereof and located between the extension of said pivot means into said passageway, and the slot in said block extending toward the end of said block opposite said antenna connecting means a distance sufficient to permit said end to clear the wall portion of said base opposite said notch as said block is pivoted into said notch to permit an antenna connected thereto to be lowered from a relatively vertical position, said block including an opening from the exterior thereof into said slot therein, said opening being of sufficient width to permit said block to be pulled clear of said pivot means, whereby said block and an antenna connected thereto can be readily removed from said base member without removal of the latter from the supporting surface on which it is mounted.
Claim 3
Dependent Claim
65 words
An antenna mount as defined in claim 1 in which at least a portion of said block has a non-circular cross-section which mates with the cross-section of a portion of said passageway when said block is slid to its lowermost position in said base member whereby the said mating portions of said block and passageway will resist twisting of said antenna when it is raised.
Claim 4
Dependent Claim
163 words
An antenna mount as defined in claim 1 in which the slot is closed at the end of the block, the base member is provided with a second notch opposite said first notch to permit said block and connected antenna to be lowered in a direction opposite that To which the block may be pivoted into said first notch, the depth of both the first and second notches being sufficient to permit the block to be slid on said pivot means when lowered into either notch, and the opening in said slot is located away from the closed end thereof whereby, to pull the block away from said base member, the block must be lowered into a notch so as to locate said opening below said pivot means and the block must be slid into the opposite notch to a position where said pivot means will pass through said opening as the block is lifted out of the upper opening of said passageway.
Claim 5
Dependent Claim
97 words
An antenna mount as defined in claim 3 in which said pivot means comprises a pair of opposed bosses integral with the wall portion of said base member, the total lengths of said bosses being less than the width of said passageway at the location of said bosses and the slot in said block is partitioned by a web so as to provide an opposed pair of slots receiving said pair of bosses, the thickness of said web not being greater than the difference between the lengths of said bosses and the said width of the passageway.
Claim 6
Dependent Claim
68 words
An antenna mount as defined in claim 4 in which said base member is provided with a flange extending radially outwardly of the lower end of the wall portion defining said passageway, said flange having openings permitting said base member to be secured to a supporting surface, and means to adjust the angle of the length of the said passageway to the slant, if any, of said surface.
Claim 7
Dependent Claim
157 words
An antenna mount as defined in claim 5 in which said adjusting means comprises a first wedge member having a planar surface contacting and at least coextensive with the lower surface of said flange and rotatable with respect thereto and an opposite wedge surface lying in a plane at an angle to said planar surface, a second wedge member having a planar surface adapted to bear on the supporting surface and an opposite angular wedge surface mating with the wedge surface of said first wedge member, said second wedge member being rotatable with respect to said first wedge member, whereby rotation of said wedge members with respect to each other and said flange permits the angle of said flange with respect to said supporting surface to be adjusted to a range of angles between the sum and the differences of the angles of the wedge surfaces of first and second wedge members to their respective planar surfaces.
