Abstract
A self-levelling support comprises a first stile (1) and a second stile (2), a first leg member (6) and a second leg member (7), each comprising an elongate element adapted to move longitudinally relative to one of the stiles (1, 2), a spacer means (3) adapted to secure the stiles (1, 2) substantially parallel to each other, and a cross member (8) adapted to pivot about a pivot pin (9) acting in a guide (10) in the spacer means (3) substantially midway between the stiles (1, 2), the cross member being connected at each end to a respective portion of the leg members, angular movement of the cross member about or with the pivot pin causing one leg member to move outwards relative to its respective stile whilst the other leg member moves inwards relative to its respective stile.
Claims14
A self-leveling support comprising:
- a first stile and a second stile;
- a first leg member and a second leg member, each comprising an elongate element adapted to move longitudinally relative to one of the stiles;
- a spacer means adapted to secure the stiles in a fixed relation to each other;
- and
- a cross member adapted to pivot about a pivot pin acting in a guide in the spacer means substantially midway between the stiles, the cross member being connected at each end to a respective portion of the leg members, angular movement of the cross member about the pivot pin causing one leg member to move outwards relative to its respective stile whilst the other leg member moves inwards relative to its respective stile.
A self-levelling support according to any preceding claim in which one or more of the leg members is received within a foot portion or pad which engages the ground.
A self-levelling support according to any preceding claim in which the spacer means comprises a rung connecting the two stiles.
A self-levelling support according to any preceding claim in which the guide in which the pivot pin is adapted to rotate comprises an elongate vertical slot.
A self-levelling support according to any preceding claim in which the pivot pin comprises a solid tubular rod which extends orthogonally through the cross-member.
A self-levelling support according to any preceding claim in which a fixing means is provided on the cross-member and the spacer means to retain the cross-member in a predetermined angular position relative to the stiles when the predetermined angular position is obtained.
