Abstract

A scaffold consists of two frames 2, bolted onto the ladders via the rung bores. The working height desired, will determine which of the two position the frame adopts, Fig. 1 shows position 1 only. Onto each frame is bolted a detachable arm 8. The two frames, and subsequently the ladders are then linked by attaching the handrail 4, which is clamped onto the detachable arms, and a light weight staging platform 3, which is clamped onto the frames. To prevent the resulting structure slipping, two securing rung bolts, are bolted through the bottom rung of each ladder, whose rings 5A, allow the base of the ladders to be secured with ropes (not shown in Fig. 1), or stakes 7. <IMAGE>

Description

SPECIFICATION Aluminium ladder-mate (work platform) The "Aluminium ladder-mate" consists of...

a. Two frames which attach to two ladders by means of rung bolts, which pass through the rung bores (see page 5) b. a lightweight platform suspended on the 2 frames, (see page 2) c. A scaffolding pole which besides acting as a safety rail, adds rigidity to the frames.

(see page 2) d. Two securing rings which are connected via a rod passing through the bottom of the ladders rungs (see page 2 and 3). The rings can be tied off to secure the base of the ladders, or stakes can be used.

HISTORY OF LADDER-PLATFORMS...

Ladder-irons have been around for some years, however, due to their lack of safety, and the enforcement of the "Factorys acts" safety at work etc, their use has declined.

Their are still a few used by one-man-businesses where the need for employee-insurance is not needed. They consisted of 2 metal frames which clipped onto the rungs of the ladders in order to support a plank.

INNOVA TION . . .

By redesigning the metal frames so that they are securely attached to the styes of the ladder (instead of the rungs), and adding a 17a4,' wide working platform, plus a scaffolding pole to add rigidity and give a safety rail to the structure. And also add the securing rings to each ladder base, you have a new, and lightweight ladder platform which is far safer than its predecessor.

1. The Alluminium Ladder Mate is a ladder scaffold which is specifically designed to be used on two alluminium ladders disposed at an acute angle to a structure.

2. The Alluminiurn Ladder Mate, as claimed in claim 1, in attached to the alluminium ladders by means of two frames.

3. The frames of the Alluminium Ladder Mate, as claimed in claim 2, attach to the alluminium ladders by rung bolts which pass through the hollow rungs, thereby clamping the members of the frames onto the ladders.

4. The frames of the Alluminium Ladder Mate as claimed in claim 2 and 3, each have an extended member, onto which is fixed a detachable arm.

5. The frames of the Alluminium Ladder Mate as claimed in claim 2 to 4 are connected by a handrail which clamps onto each detachable arm.

6. Onto the frame of the Alluminium Ladder mate as claimed in claim 2 to 5 is clamped a lightweight staging platform.

7. The alluminium ladders (plus the attached structure as claimed in claims 1 to 6) are each secured at their base by securing rung bolts which pass through the bottom rung of each ladder thereby providing rings with which the base of each ladder may be secured by ropes, stakes, or other means, not specified herein.

8. An Alluminium Ladder Mate substantially as described herein with reference to Figs. 1 to 5 of the accompanying drawings.
