Abstract
Abstract A bracket for mounting an outboard motor on a boat, said bracket comprising a parallel linkage arrangement for moving the motor between respective end positions above and below the boat and a latch arrangement for latching an operating lever in either end position. The latch arrangement is released by a force applied manually in a direction from the bracket towards the boat. The load on the bracket is preferably prevented from bearing on the latch arrangement and PTFE washers are used for tight fitting of the linkage without jamming.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A bracket for an outboard motor comprising a first bracket assembly adapted to be mounted on a boat, a second bracket assembly adapted to mount a motor, at least two links in a spaced apart parallel relationship pivotally mounted on, and interconnecting the bracket assemblies for movement, in use, of said second bracket assembly and thus the motor relative to said first bracket assembly between respective end positions above and below said first assembly, an operating lever having a latch arrangement and a manually operable handle arrangement, the latch arrangement being arranged to latch the lever in either of the two end positions, a pin on said second bracket assembly, and a spring extending between the operating lever and said pin for biasing said lever in a direction for latching the latch arrangement, said pin being so located that it rests upon one of said links and carries the weight of the motor when said second bracket assembly is latched in its end position below said first bracket assembly.
Claim 2
Dependent Claim
169 words
A bracket for an outboard motor comprising a first bracket assembly adapted to be mounted on a boat, a second bracket assembly adapted to mount a motor, at least two links in a spaced apart parallel relationship pivotally mounted on, and interconnecting the bracket assemblies for movement, in use, of said second bracket assembly and thus the motor relative to said first bracket assembly between respective end positions above and below said first assembly, an operating lever having a latch arrangement and a manually operable handle arrangement, the latch arrangement being arranged to latch the lever in either of the two end positions, a pin on said second bracket assembly, and a spring extending between the operating lever and said pin for biasing said lever in a direction for latching the latch arrangement, said pin being so located that it rests upon one of said links and carries the weight of the motor when said second bracket assembly is latched in its end position below said first bracket assembly.
Claim 3
Dependent Claim
37 words
A bracket according to claim 1, wherein the operating lever is pivotally mounted adjacent to one end on one of said links and is connected with the other of said links by means of the latch arrangement.
Claim 4
Dependent Claim
44 words
A bracket according to claim 1 wherein the latch arrangement and spring are so mutually arranged that the lever is moved toward said first bracket, against the force of the spring, to unlatch the lever in each end position of said second bracket assembly.
Claim 5
Dependent Claim
35 words
A bracket according to claim 1, wherein the pin mounts a pair of bushes, which bear the applied weight and define a central groove, the biasing spring having one end mounted in the central groove.
Claim 6
Dependent Claim
13 words
A bracket according to claim 4, wherein the bushes are formed of nylon.
Claim 7
Dependent Claim
34 words
A bracket according to claim 4, wherein the pin is positioned substantially centrally between the pivots for the links on said second bracket assembly and the biasing spring extends substantially parallel to the links.
Claim 8
Dependent Claim
87 words
A bracket according to claim 1, wherein a pair of tension springs which extend between the operating lever and a pin on said second bracket assembly, provide the biasing force, a further pin being provided on said second bracket assembly parallel to said first mentioned pin, the links being engageable with a respective one of the pins in the respective end position of said second bracket assembly so as to direct the load applied to the bracket on to the pins and not to the latch arrangement.
Claim 9
Dependent Claim
16 words
A bracket according to claim 7, wherein the tension springs extend substantially parallel to the links.
Claim 10
Dependent Claim
129 words
A bracket according to claim 2, wherein said one link is defined by a pair of parallel blades and pivots are provided therefor on said first and second bracket assemblies, the parallel blades being spaced apart axially on the pivots, the operating lever is defined by a pair of parallel blades spaced apart axially on a pin extending between the blades of said one link and defining a pivot for the operating lever, said operating lever blades having means defining shaped openings therein, and the other link is defined by a single blade extending between the blades of the operating lever and having a projection on each side thereof extending into the shaped opening in the respective blade of the operating lever so as to define the latch arrangement.
Claim 11
Dependent Claim
32 words
A bracket according to claim 9, wherein the pivots for the links are defined by pins which mount nylon bushes and PTFE washers, to enable tight fitting of the pivots without jamming.
