Benefits of technology

[0005]An object of the invention is to eliminate this drawback and to provide a scaffold capable of being displaced as well as adjusted from four corners simultaneously even in terrain with major height differences. The scaffold is safe during its displacement, nor does it topple over.

Problems solved by technology

With these scaffolds, the disengagement / engagement of adjustment in rough terrain causes the scaffold to topple over.

Embodiment Construction

[0010]A scaffold 20 shown in FIG. 1 comprises tubular corner members 1, which are connected to each other at the ends of the scaffold by means of substantially horizontal tubular cross-members 2, preferably by welding, thus producing gable elements 23 (see FIG. 2). The tubular material comprises preferably aluminum, e.g. aluminium of alloy T6. In this exemplary case, the aluminium tube has a diameter of 50 mm and a wall thickness of 2 mm. The gable elements 23 present at the opposite ends of the scaffold are connected to each other by means of work platforms 21 and by substantially horizontal rear-side tubes 2b and diagonal front-side bracing tubes 2b. The passage between work platforms at various levels is provided by means of ladders 22, extending adjacent to the work platforms between the gable elements 23 within a frame structure established by the tubular corner members 1 and the tubular cross-members 2, 2a, 2b connecting the same. Each tubular corner member has its bottom end ...

Abstract

A movable scaffold (20) has one or more fixed work platforms (21). The scaffold frame element has four upright tubular corner members (1) connected by tubular cross-members (2, 2a, 2b). Each tubular corner member has a bottom end provided with a wheel (15) for allowing a displacement of the scaffold. The scaffold is provided with elements for adjusting its height. Between each tubular corner member (1) and the wheel (15) at its bottom end are provided vertical adjustment elements (5) to enable an individual vertical adjustment of each wheel relative to its associated tubular corner member (1) while effecting a displacement of the scaffold (20), the scaffold being thus safely movable even on rough foundation.

Description

[0001]This application is a U.S. national stage application of International App. No. PCT / FI2005 / 050433, filed Nov. 23, 2005, the disclosure of which is incorporated by reference herein, and claims priority on Finish App. No. 20050397, filed Apr. 18, 2005.STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]This invention relates to a movable scaffold.[0004]In prior known scaffolds, having the four corners thereof provided with an adjustment feature, such as e.g. in a scaffold described in U.S. Pat. No. 4,293,054 which has a vertically movable hoisting platform, the scaffold has its vertical adjustment elements consisting of adjustable legs not allowing for a displacement of the scaffold during or after the adjustment procedure. With these scaffolds, the disengagement / engagement of adjustment in rough terrain causes the scaffold to topple over.SUMMARY OF THE INVENTION[0005]An object of the i...
