Claim 1
Independent Claim
306 words
A fitment for a prop, said fitment being adapted to support at least one shuttering element of the type used with concrete formwork, said fitment being movable between a full support position, and preliminary and full strip positions, said fitment comprising a shank having a headplate fixed to the top end thereof, said shank being connectable to said prop in fixed relation thereto, a support tube slidably and rotatably disposed in coaxial relation with said shank, a shuttering tube slidably disposed in coaxial relation with said shank and said support tube, said shuttering tube mounting at least one shuttering support member thereon, at least one support ear mounted to one of said support tube and said shuttering tube and extending substantially radially therefrom, and the other of said support tube and said shuttering tube defining at least one ear slot adapted to receive said support ear therein, said support ear cooperating with a contact surface on that tube to which said ear is not fixed to maintain said support and shuttering tubes in the full support position, anti-rotation means interconnecting said shank and said shuttering tube, said anti-rotation means permitting sliding motion of said shuttering tube relative to said support tube, but preventing rotational motion of said shuttering tube relative to said support tube, and cam means interconnecting said shank and said support tube, initial rotation of said support tube relative to said shank and said shuttering tube causing said cam means to lower slightly said shuttering tube away from said headplate to the preliminary strip position, and further rotation of said support tube relative to said shank causing said support tube''s ear to move out of contact with said contact surface into alignment with said shuttering tube''s ear slot causing said shuttering tube to drop further away from said headplate into the full strip position.
Claim 2
Dependent Claim
306 words
A fitment for a prop, said fitment being adapted to support at least one shuttering element of the type used with concrete formwork, said fitment being movable between a full support position, and preliminary and full strip positions, said fitment comprising a shank having a headplate fixed to the top end thereof, said shank being connectable to said prop in fixed relation thereto, a support tube slidably and rotatably disposed in coaxial relation with said shank, a shuttering tube slidably disposed in coaxial relation with said shank and said support tube, said shuttering tube mounting at least one shuttering support member thereon, at least one support ear mounted to one of said support tube and said shuttering tube and extending substantially radially therefrom, and the other of said support tube and said shuttering tube defining at least one ear slot adapted to receive said support ear therein, said support ear cooperating with a contact surface on that tube to which said ear is not fixed to maintain said support and shuttering tubes in the full support position, anti-rotation means interconnecting said shank and said shuttering tube, said anti-rotation means permitting sliding motion of said shuttering tube relative to said support tube, but preventing rotational motion of said shuttering tube relative to said support tube, and cam means interconnecting said shank and said support tube, initial rotation of said support tube relative to said shank and said shuttering tube causing said cam means to lower slightly said shuttering tube away from said headplate to the preliminary strip position, and further rotation of said support tube relative to said shank causing said support tube''s ear to move out of contact with said contact surface into alignment with said shuttering tube''s ear slot causing said shuttering tube to drop further away from said headplate into the full strip position.
Claim 3
Dependent Claim
47 words
A fitment as set forth in claim 1, said anti-rotation means comprising an anti-rotation slot defined in one of said support and shuttering tubes, and an anti-rotation pin fixed to the other of said support and shuttering tuBes, said anti-rotation pin being received in said anti-rotation slot.
Claim 4
Dependent Claim
48 words
A fitment as set forth in claim 1, said cam means comprising a cam surface defined in one of said support and shuttering tubes, and a cam pin fixed to the other of said support and shuttering tubes, said cam pin being in contact with said cam surface.
Claim 5
Dependent Claim
27 words
A fitment as set forth in claim 1, said fitment''s full strip position being established by one of support ear/ear slot structure and said anti-rotation means structure.
Claim 6
Dependent Claim
30 words
A fitment as set forth in claim 1 including a handle fixed to said support tube, said handle permitting manual rotation of said support tube relative to said shuttering tube.
Claim 7
Dependent Claim
46 words
A fitment as set forth in claim 1, said ear being positioned relative to said ear slot in said fitment''s full support position so as to require rotation of said support tube through about 90* prior to achieving alignment of said ear with said ear slot.
Claim 8
Dependent Claim
32 words
A fitment as set forth in claim 6, there being at least two ears and at least two ear slots, said ears and ear slots being symmetrically disposed relative to said shank.
