Abstract

A removable boat seat attachment having a seat rotatably mounted on a base member which is selectively extendable in length to accommodate different widths of thwarts. The base member has thwart or seat board engaging members which co-operate with an adjustable clamp having thwart or seat board engaging portions wherein the base member and the clamp co-operate to engage opposite edges of the thwart or seat board for securing the base member thereto. Quick release locking type fasteners have portions secured to the base member and the clamp operable for urging and normally maintaining the thwart engaging portions in clamping engagement and removably securing the boat seat attachment thereto.

Claims

1. A removable seating device for attachment to a thwart connected at opposite ends to opposite sides of a boat, said seating device comprising:

a. a base structure having separable first and second sections with thwart edge engaging portions, said edge engaging portion on the first section being opposed to said edge engaging portion on the second section;

b. said first section being a main section adapted to rest on a thwart having opposed edges with the respective thwart edge engaging portion being engageable with one of said opposed edges;

c. a seat member;

d. means mounting said seat member on said main section;

e. separable connecting means having portions on each of said first and second sections, said means being operable for selectively releasing said sections one from the other for removal of the seat and base structure from the thwart and to connect said sections and draw one toward the other for affecting clamping of the opposed thwart edges between said thwart engaging portions;

f. said separable connecting means including a toggle structure with an operating arm pivoted on a portion of the toggle structure which is mounted on one of said first and second base sections and a link pivoted on the arm and extending therefrom, said link having a free end portion separably engaging the other portion of the toggle structure which is mounted on the other of said first and second base sections, said operating arm being movable between a retracted position and an extended position.

2. A removable seating device as set forth in claim 1 wherein said thwart edge engaging portions include:

a. a first member depending from one end of said main section remote from said second base section, said first member being hook shaped and opening generally toward said second base section and receiving one of said opposed thwart edges therein;

b. a second member depending from said second base section, said second member being hook shaped and opening generally toward said first member and receiving the other said opposed edge therein.

3. A removable seating device as set forth in claim 1 wherein:

a. said main section of the base structure having relatively movable portions wherein said main section is selectively extendable in length and the spacing between said opposed thwart edge engaging portions being adjustable for accommodating different width thwarts;

b. means cooperating with the relatively movable portions of said base structure and normally securing same in the selected extended position.

4. A removable seating device as set forth in claim 3 wherein said seat member mounting means includes:

a. a swivel bearing plate secured to said main base structure and having a platform rotatable relative thereto;

b. means securing said seat member to said platform wherein said seat member is rotatable relative to said base structure and said thwart.

5. A removable seating device as set forth in claim 4 wherein said base structure relatively movable portions includes:

a. a plurality of spaced apart and generally parallel channel forming members on said main base section with said channels extending in a direction generally between Said opposed thwart edge engaging portions;

b. elongate slide members each being slidably received in a respective said channel and having a free end adjacent said second base section with said free ends being movable relative to and away from said channel members thereby providing extension of the length of said base structure and said connecting means being on said free ends of said second base section;

c. fastening means on said main base section and selectively engaging said slide members to secure same in selected extended position.

6. A removable seating device as set forth in claim 5 wherein:

a. said toggle structure being a plurality with each having an abutment member secured to one of said second base section and a respective said slide member, each said toggle structure having a body portion secured to said second base section and said slide member;

b. said links each being engageable with a respective abutment member wherein pivoting of said operating arm to the retracted position urges said opposed thwart engaging portions into engagement with said opposed thwart edges.

7. A removable seating device as set forth in claim 5 including:

a. resilient material secured in covering relation to under surfaces of said first and second base sections for engaging portions of said thwart preventing marring of said thwart by said base structure.

8. A removable seating device for attachment to a thwart connected at opposite ends to opposite side of a boat, said seating device comprising:

a. a base structure having first and second sections with opposed thwart edge engaging portions;

b. said first base section being adapted to rest on a thwart having opposed edges with the respective thwart edge engaging portion being engageable with one of said opposed edges, said first base section having selectively adjustable portions movable toward and away from the respective thwart engaging portion thereof to vary the spacing therebetween, said second base section thwart engaging portion being engageable with the other said opposed edge;

c. a seat member and swivel means mounting same on said first base section;

d. connecting means having portions thereof on said second section and said adjustable portions adjacent said second section, said connecting means including a toggle structure having an operating arm pivoted on a base member that is on one of said adjustable portions and second section and a link pivoted on said operating arm and having an end remote from said pivoted end in engagement with an abutment member on the other of said adjustable portions and second section, said operating arm being movable from an extended position to a retracted position selectively drawing said first and second base sections toward one another for effecting clamping of the opposed thwart edges between said thwart engaging portions.

9. A removable seating device as set forth in claim 8 wherein said thwart edge engaging portions include:

a. at least one first member depending from one end of said first base section remote from said second base section, said first member being hook shaped and opening generally toward said second base section and adapted for receiving one of said opposed thwart edges therein;

b. at least one second member depending from said second base section, said second member being hook shaped and opening generally toward said first member and adapted for receiving the other said opposed thwart edge therein.
