Abstract
Abstract A tripod support having open and closed positions comprises a housing and three legs which extend downwardly and outwardly from the housing into contact with the ground when the support is in the open position. Two of the legs are rotatable about generally upright axes, referred to the in use open position of the support, to bring the support into the closed position wherein the legs are in a substantially parallel side-by-side relationship.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A multi-legged support having open and closed positions, the support comprising: a housing and at least threee legs which in use of the support in the open position extend downwardly and outwardly from the housing into contact with the ground; at least two of the legs being rotatable relative to the housing about generally upright axes, referred to the in use open position of the support, to bring the support into the closed position wherein the legs are in a substantially parallel side-by-side relationship; and locking means for locking the legs in the open position and/or in the closed position, said locking means includes a respective multi-sided head non-rotatably fixed relative to an upper end of each rotatable leg and a removable housing cover which co-operates with the sides of each head to lock the head in a selected one of two angular positions corresponding respectively to the closed and open positions of the legs.
Claim 2
Dependent Claim
155 words
A multi-legged support having open and closed positions, the support comprising: a housing and at least threee legs which in use of the support in the open position extend downwardly and outwardly from the housing into contact with the ground; at least two of the legs being rotatable relative to the housing about generally upright axes, referred to the in use open position of the support, to bring the support into the closed position wherein the legs are in a substantially parallel side-by-side relationship; and locking means for locking the legs in the open position and/or in the closed position, said locking means includes a respective multi-sided head non-rotatably fixed relative to an upper end of each rotatable leg and a removable housing cover which co-operates with the sides of each head to lock the head in a selected one of two angular positions corresponding respectively to the closed and open positions of the legs.
Claim 3
Dependent Claim
23 words
A support according to claim 1, wherein there are only three legs of which one leg is non-rotatably fixed relatively to the housing.
Claim 4
Dependent Claim
255 words
A support comprising: a housing having a top side and a bottom side and at least three legs each mounted on the housing by an upper end and extending downwardly from the bottom side of the housing to terminate in a respective ground-engaging end remote from the housing; the upper ends of at least two legs being rotatable about respective axes extending in the top-to-bottom direction of the housing with the ground-engaging end of each such leg being laterally offset from the rotational axis of the upper end thereof; whereby the legs may be rotated between a first position wherein all the legs of the support are in a substantially parallel side-by-side relationship and a second position wherein the ground-engaging ends of the legs are spaced apart to form a stable stand for the housing; said upper ends of said at least two legs are disposed substantially parallel to one another in the housing and each is rotatable about its own axis, each of the said two legs diverging outwardly from the axis of the upper end in the direction towards the ground-engaging end; and locking means for locking the legs in the open position and/or in the closed position, said locking means includes a respective multi-sided head non-rotatably fixed relative to an upper end of each rotatable leg and a removable housing cover which co-operates with the sides of each head to lock the head in a selected one of two angular positions corresponding respectively to the first and second positions of the legs.
Claim 5
Dependent Claim
255 words
A support comprising: a housing having a top side and a bottom side and at least three legs each mounted on the housing by an upper end and extending downwardly from the bottom side of the housing to terminate in a respective ground-engaging end remote from the housing; the upper ends of at least two legs being rotatable about respective axes extending in the top-to-bottom direction of the housing with the ground-engaging end of each such leg being laterally offset from the rotational axis of the upper end thereof; whereby the legs may be rotated between a first position wherein all the legs of the support are in a substantially parallel side-by-side relationship and a second position wherein the ground-engaging ends of the legs are spaced apart to form a stable stand for the housing; said upper ends of said at least two legs are disposed substantially parallel to one another in the housing and each is rotatable about its own axis, each of the said two legs diverging outwardly from the axis of the upper end in the direction towards the ground-engaging end; and locking means for locking the legs in the open position and/or in the closed position, said locking means includes a respective multi-sided head non-rotatably fixed relative to an upper end of each rotatable leg and a removable housing cover which co-operates with the sides of each head to lock the head in a selected one of two angular positions corresponding respectively to the first and second positions of the legs.
Claim 6
Dependent Claim
23 words
A support according to claim 3, wherein there are only three legs of which one leg is non-rotatably fixed relatively to the housing.
