Abstract
An angled pivot system (26) can be fitted to a conventional roof crawler to give the roof crawler a range of angles to the horizontal roof ridge (28) for access to the angled hip ridge and the angled valley troughs and general roof areas. The system is used with valley supports (16) and connected by an aid (18), Fig 6 to a roof access ladder (32). When used in conjuction with each other these components provide access for the user with the roof crawler, and also assist with comfort and safety essential to roofwork at awkward places. <IMAGE>
Description
ROOF CRAWLER ANGLE SYSTEM
This invention relates to a roof crawler pivot and its seperate but
essential parts.
Roof crawler ladders are a familiar sightaand are in frequent use to
those in the building trade, consisting of a light weight ladder with
a double hook fixed to the end with the hook part going over the ridge
of a roof to give a fixed 9o angle between the roof ridge and crawler.
This configuration works for access to the horizontal ridge but not
for angled hip ridges or trough valleys.
This present invention with its seperate parts once fitted to a
conventional roof crawler provides, apart from its 90S angle other
angles to gain access to hip ridges, roof valley troughs and other parts
of the roof from the fixed point of the roof crawler horizontal ridge
hook, with the advantage of the angle pivot plate which pivots on a
main pivot pin holding the two plates together and is secured at desired
angles by securing pins.
A specific embodiment of this invention will now be described by way
of example with reference to the accompanying drawings in which
Figure 1 shows in perspective the main pivot device for the roof crawler.
Figure 2 shows in perspective a hip ridge hook and roof valley sprag
which are both interchangable with the crawler bracket shown.
Figure 3 shows in perspective the roof crawler rest aid.
Figure 4 shows in plan the crawler pivot in its 900 normal position
and also and also in one of its angled positions together with showing
the hip ridge hook fixed, which retains the crawler in a position
at the hip ridge.
It also shows the valley sprag fixed to the crawler to hold
it away from the valley.
Figure 5 shows the front elevation of the roof crawler aid which is
adaptable for left and right hand use.
Figure 6 shows the crawler aid in perspective with the roof crawler and access ladder.
Refering to the drawings, the crawler pivot system is comprised of two pivot plates 1. and 2. which are connected by a main pivot pin 3. as in Fig 1.
The top pivot plate 1. is connected to a crawler ridge hook with side and or bottom connections 6. in Fig. 1. The bottom pivot plate 2. is connected to the crawler ladder by it s fixing brackets 8.
shown in Fig 1. and completes the pivot part.
before moving the roof crawler to a desired position, one of the two divices, hip ridge hook 10. or the roof valley sprag 16. is connected to the roof crawler with the fixing bracket 13. All are shown in Fig. 2.
To move the crawler from its normal position to gain access to a hip ridge 30. shown in plan in Fig. 4. remove the two securing pins 7. in Fig. 1., swing the roof crawler ladder to it s desired angle against the hip ridge, or in the case of the valley trough sprag to the valley 31. in plan in Fig.4. and replace the two securing pins in the corresponding holes 4. in Fig. 4. and replace the two securing pins in their corresponding holes g; in Fig. 4.
With the addition of the pivot plates 1. and 2. in Fig. 1. (made of a comparable light - weight metal as existing roof access equipment) to the roof crawler, the crawler rest aid in Figs. 3, 5, and 6., being part of the system, has been designed to combat the small but noticable extra weight incurred.
The crawler rest aid is fitted to the "backside" of the roof access ladder as shown 'in situ.' in Fig. 6. resting on the roof edge with it's support leg part 21. in Fig. 6., which counteracts the weight of the roof crawler at any stage of manouvre.
The returning spring for the crawler rest aid hooks brings the hooks 19. Fig. 6., back to rest, as the hooks are so designed to
give' gr rotate on the crawler rest aid body 18. in Fig. 6., to a stop. ?3. in Fig. 6. and return for catchment of the crawler at any stage. This system allows the roof crawler, whilst being run up on the crawler aid body 18. in Fig. 6. to be in close contact at all times with this aid.The incorparation of this part of the system for crawler placement gives the user the oppertunity to rest the crawler whenever desired or when in any difficulty.
The user can also use the rest aid to hold the roof crawler and act as an anchor point.

Claims (1)
- CLAIMS.i. The angled pivot system with it's separate parts which form a whole when fitted to a roof crawler, gives access to other angles of roof in either direction which a normal roof crawler does not allow..2. An angled pivot system as claimed in Claim 1. which can be moved to several angles in either direction with the added provision of the hip ridge hook device which gives support at a hip ridge as well as support at the pivot.3. An angled pivot system as claimed in Caim 1. or Claim 2. also with the ability to provide support for the roof crawler against a roof valley trough by it's roof valley device.4. An angled pivot system as claimed in Claim 1, Claim 2 and Claim 3, with the inclusion of the roof crawler rest aid.5. An angled pivot system as claimed in all previous Claims, with the crawler rest aid having the ability to be used as an anchor point for the roof crawler1 together with the other devices, and as a rest for the crawler whenever desired, either when going up or coming down the roof access ladder or whilst on the roof.6. An angled pivot system as described herein with reference to Figs.1. to 6. in accompanying drawings
