Abstract
Abstract Frictional grip-boards (as defined in UK Patent Application No. 8235220, Serial No. 2131475A provide the basis for various devices which enhance the stability of ladders and expand their range of uses. Disclosed are: 1. A stand-off enabling the top of a ladder to be supported by a sloping roof without risk of slippage, and which may be fitted with a platform to provide a working surface and/or safe access to the roof, (Fig. 1). 2. A ladder stand-off for use on vertical walls, but with exceptional frictional grip and again the option of an added platform as a working aid, (Fig. 2). 3. Grip-boards adapted for clipping onto one side of a ladder so that it may be used as a self-adhering roof-scaling device without separate anchorage, (Fig. 3). 4. A supportive base employing on its underside a grip-board whose angle may be adjusted to accommodate sloping terrain, thus providing secure ladder placement in otherwise difficult locations, (Fig. 4). <IMAGE>

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
71 words
Devices for use in conjuction with ladders to facilitate safe access to pitched roofs and vertical walls, or to provide a stable base on sloping or slippery substrata, by virtue of the frictional properties of boards having undersides comprising a depth of flexible urethane foam, or other foam plastics, foam rubbers or materials with similar mechanical properties, such 'grip-boards' being as described and defined in co-pending U.K. Patent
Application No. 8235220.
Claim 2
Dependent Claim

Application No. 8235220.
Claim 3
Dependent Claim
75 words
A stand-off which may be attached at or near the top of a ladder by any convenient means and whose supportive member comprises a grip-board or boards according to claim 1, the said board(s) being angled and pivoted or otherwise compliantly mounted such that its (their) underside(s) engages the lower reaches of a sloping roof's surface as the ladder is placed in position, thus providing a stable support while holding the ladder clear of protrusions.
Claim 4
Dependent Claim
81 words
A stand-off according to claim 2, fitted with a permanent or detachable platform which is horizontal along its lateral axis when the associated ladder is in its working position, and which may be either fixed or eqipped with adjustable means for maintaining horizontality along its fore-and-aft axis over a range of roof pitches, to provide a level working surface onto which a person climbing the ladder may step to gain access to the roof, or on which materials can be stood.
Claim 5
Dependent Claim
35 words
A stand-off according to claim 2, but with its grip-board(s) so angled as to engage a vertical wall, thus holding the ladder away from such a wall while retaining a firm frictional grip upon it.
Claim 6
Dependent Claim
34 words
A stand-off according to claim 4, but fitted with a platform as in claim 3, such a platform providing a surface on which materials may be stood while the user works from the ladder.
Claim 7
Dependent Claim
16 words
A universal ladder stand-off incorporating any combination of the facilities detailed in claims 2 to 5.
Claim 8
Dependent Claim
49 words
Two or more grip-boards according to claim 1, with means for temporary but secure attachment to one side of a ladder to provide a high frictional grip, enabling the ladder to be placed up a sloping roof and used for scaling the roof without the need for other supports.
Claim 9
Dependent Claim
72 words
A base which provides a secure abutment for a ladder's feet, such a base carrying on its underside a grip-board according to claim1, the inclination of which is adjustable to accommodate any slope or irregularity in the substratum while leaving the main body of the ladder-base horizontal, with means provided to lock the upper and lower parts of the device firmly together at whatever angle may be necessary to stabilize the ladder.
Claim 10
Dependent Claim
26 words
Grip-boards, stand-off, stand-offs with platforms, and ladder-bases as hereinbefore described, with general reference to the drawings labelled
Figures 1, 2, 3 and 4 accompanying the Specification.
Claim 11
Dependent Claim
26 words
Grip-boards, stand-off, stand-offs with platforms, and ladder-bases as hereinbefore described, with general reference to the drawings labelled
Figures 1, 2, 3 and 4 accompanying the Specification.
