Abstract
A support structure for use with a ladder or similarly functioning access platform. The support structure has an extendible first section attached to an extendible second section, the first section being substantially perpendicular to the second section, wherein the first section is adapted to be laterally extendible from the side rails or stiles and the second section is extendible to allow ground engaging means located remote from the first section to contact the ground, in use, and a coupling for connecting the support structure to the stiles, the coupling being positioned remote from the connector. The support structure is preferably located near the mid-point between the top and bottom of the ladder and greatly improves the stability of the ladder in use.
Claims (37)
1. A height access apparatus which comprises: first side rails or stiles which support a plurality of rungs, the rungs being substantially equally spaced apart along the length of the side rails or stiles; second side rails or stiles which support either, one or more brace, the one or more brace extending between the second side rails, or a plurality of rungs, the rungs being substantially equally spaced apart along the length of the side rails or stiles; a connector to which the first side rails or stiles and the second side rails or stiles are attached; a support structure attached to the first side rails or stiles and/or the second side rails or stiles, the support structure comprising: an extendible first section attached to an extendible second section, the first section being substantially perpendicular to the second section, wherein the first section is adapted to be laterally extendible from the side rails or stiles and the second section is extendible to allow ground engaging means located remote from the first section to contact the ground, in use, and a coupling for connecting the support structure to the stiles, the coupling being positioned remote from the connector.
2. The support structure as claimed in claim 1 wherein, the connector is a top cap or top plate.
3. The support structure as claimed in claim 1 or claim 2 wherein, the coupling is positioned at least one fifth of the distance along the first and/or second rails or stiles from the connector.
4. The support structure as claimed in any preceding claim wherein, the coupling is positioned substantially one half of the distance along the first and/or second rails or stiles from the connector.
5. The support structure as claimed in any preceding claim wherein, the first section comprises a sleeve which accommodates an arm which is movable along at least part of the length of the sleeve to extend and retract the first section.
6. The support structure as claimed in any preceding claim wherein, the arm is rotatably mounted in the sleeve.
7. The support structure as claimed in any preceding claim wherein, the arm is fixedly connected to the extendible second section.
8. The support structure as claimed in any preceding claim wherein, the sleeve is provided with a collar which is inserted into the side rail or stile of the height access apparatus.
9. The support structure as claimed in any preceding claim wherein, the sleeve is rotatably mounted in the collar.
10. The support structure as claimed in any preceding claim wherein, the support structure as claimed in any preceding claim wherein, the first section is provided with a locking mechanism to prevent rotational and/or lateral movement of the sleeve and the arm.
11. The support structure as claimed in any preceding claim wherein, the locking mechanism is a locking pin receivable by one or more hole in the sleeve and/or arm.
12. The support structure as claimed in any of claims 1 to 10 wherein, the locking mechanism is located on the collar .
13. The support structure as claimed in any preceding claim wherein, the second section comprises a sleeve which accommodates a leg which is moveable along at least part of the length of the sleeve to extend and retract the second section.
14. The support structure as claimed in any preceding claim wherein, the leg of the second section has a locking mechanism which fixes the length of the second section.
15. The support structure as claimed in any preceding claim wherein, the locking mechanism is a compression fitting situated between the sleeve and the leg.
16. The support structure as claimed in any of claims 1 to 14 wherein, the first section is a extendable member connectable to a lateral member of the height access apparatus.
17. The support structure as claimed in any of claims 1 to 14 wherein, the second section is a extendable member.
18. The support structure as claimed in claim 17 wherein the extendable member has an adjustable sliding brake clamp.
19. The support structure as claimed in claim 17 or 18 wherein, the extendable member has an adjustable sliding brake clamp with bolt and wing nut .
20. The support structure as claimed in any preceding claim wherein, the leg of the second section has a thread adapted to receive a locking nut, the position of which sets the length of the leg.
21. The support structure as claimed in any preceding claim wherein, the leg has an interchangeable foot, which are shaped for different ground conditions.
22. The support structure as claimed in claim 21 wherein, the foot has a surface area at least twice that of the leg cross section, the foot being of particular use on soft ground.
23. The support structure as claimed in claim 21 wherein, the foot is T shaped to provide additional stability on hard ground.
24. The support structure as claimed in any preceding claim wherein, the angle between the first section and the second section is 90° +/- 20°.
25. The support structure as claimed in any preceding claim wherein, a pair of supports is connectable one on either side of a height access apparatus on both the first side rails or stiles and the second side rails or stiles.
26. The support structure as claimed in claim 25 wherein, the first sections of said supports are mounted coaxially .
27. The support structure as claimed in claim 25 wherein, the first sections of said supports are mounted axially offset.
28. The support structure as claimed in claim 25 wherein, the second section is connectable to a lateral member of a height access platform to allow easy storage of the support apparatus.
29. The support structure as claimed in any preceding claim wherein, the second section of the support apparatus is parallel to the lateral member of the height support apparatus.
30. The support structure as claimed in any preceding claim wherein, the second section of the support apparatus is curved.
31. The support structure as claimed in claim 1 to 29 wherein, the second section comprises at least two sleeves with corresponding legs, the sleeves being rotatably mounted at the connection with the arm at the first section, such that, in use, the legs may be positioned in front of and behind the height access apparatus.
32. The support structure as claimed in claim 31 wherein, the second section may further comprise a pressure sensor to warn the user of over-leaning and/or overloading.
33. The support structure as claimed in claim 31 wherein, the pressure sensor can be fitted at or near the end of the second section remote from the first section.
34. The support structure as claimed in any preceding claim wherein the first section and second section of the support structure are connected together by a joint.
35. The support structure as claimed in claim 34 wherein, the joint has a sleeve which receives the first section and a second sleeve which receives the second section .
36. A support structure for use with a ladder or similarly functioning access platform, the support structure comprising: an extendible first section attached to an extendible second section, the first section being substantially perpendicular to the second section, wherein the first section is adapted to be laterally extendible from the side rails or stiles and the second section is extendible to allow ground engaging means located remote from the first section to contact the ground, in use, and a coupling for connecting the support structure to the stiles, the coupling being positioned remote from the connector.
