Abstract

A adjustable mobile work stand is provided with means for attaching a workpiece to a rotatable support bar and means to hold additional parts or tools. The support bar (4, Fig 4.3) is mounted through a tube (5, Fig 4.3) located at the upper end of a telescopic stand comprising a pair of wheels and a foldable support leg. The support bar (4, Fig 4.3) is rotatable within the tube (5, Fig 4.3) and its position can be fixed by the tightening of a pin (6, Fig 4.3) to engage the support bar through an aperture in the stand tube (Fig 4.3). The pin is made of material, such as brass, that will expand on heating to ensure that the locking mechanism remains tight. The support bar carries two support arms equipped with hooks to hold the workpiece in place. Extensions are formed with oval holes and inserted into the end of the support bar to hold parts or tools (Fig 4.2).

Description

1 2343421 ADJUSTABLE APPARATUS FOR THE FIXING OF LOOSE PARTS DURING

CONSTRUCTION This invention comprises an adjustable apparatus for the fixing of loose parts during construction. The apparatus is made of iron tubes with different dimensions and com prises a loose wagon with two wheels which are placed so that the direction of driving is the same as the direc tion of the parts placed on the apparatus. The wagon com prises a high neck which permits a good adjustment. of height and a rear leg which can be folded towards the wheels in order to take up as little room as possible. In the high neck of the wagon a f ixing element is placed provided with a turning element at the top, said turning element comprising two different circular tube dimensions inside each other. Said turning element is provided with a stop and a horizontal carrying-arm on which loose hook carriers and hooks are mounted. inside this horizontal carrying arm elongation elements are placed, said ele- ments comprising an oblong hole at the end. In this way it is possible to use bolts tightened by means of eye screws and nuts. The bolts can hold small loose parts if they are provided with a thread.

State of the art For treatment of loose parts horses on which the object is placed are often used. Known are also wires with hooks hanging from the ceiling carrying the parts, also fixa tions which cannot rotate the object treated as well as fixations where the treated object can be moved according to need but only in fixed positions are known. In the treatment of small loose parts an additional part is needed as support.

2 The technical problem to be solved The known technologies are not optimal in use since such apparatuses typically take up a lot of room also when not in use. Also no solutions are seen where fixation of loose parts occur as an integrated part of the apparatus, but only with the mentioned additional parts. Also required is a solution where the turning and locking mechanism is fully enclosed within the apparatus in order to increase functionality in the long term and reduce the size of the apparatus.

With the new invention the object is to make a better type of apparatus which fulfils the following three ele- ments: 1) foldable, 2) that loose parts can be fixed with an integrated part of the apparatus, 3) that the turning mechanism can be enclosed in the apparatus to ensure a longer life time and a minimal size.

The new technology The new aspects of this invention are that the wagon comprises an adjustable rear leg comprising an upside down T loosely bolted to the neck of the wagon with a bolt and a self locking nut which ensures that the leg can be folded close to the wheels yet only with use of a certain force. It is further a novelty that loose parts can be fixed with an integrated part of the apparatus because of the oval hole in the adjustable support bars. New is also that the turning element comprises two circular tubes inside each other with a milled stop groove ensuring the desired stop point as well as ensuring a long lifetime of the apparatus since the whole turning mechanism is enclosed within it. Further, this solution ensures a mini- mal size of the apparatus.

3 The technical effect of the invention If the above mentioned technology, basic principles and the state of the art are applied, the apparatus can be used also in places where the space is limited because the apparatus can be folded into an almost flat unit when not in use. Furthermore, the fixation units for loose parts are now an integrated part of the apparatus and the turning mechanism is enclosed and protected and therefore a longer lifetime is ensured as well as a minimal size.

The invention and its use are described and shown in the following drawings.

Drawings The figures 1-3 show well know technology, figure 4 shows the new technology. In specific the figures 4.1, 4.2 and 4.3 show the principles that make the new technology possible.

Figure 4.2 shows a loose part 1, such as a mirror, being fixed. The loose part 1 is fixed by an assembly 2 consisting of a sliding bar with an oval hole, eyebolt, stud bolt and wing nut. Figures 4.3 show front and side views (the latter being in partial section) of the turning element comprising stop groove 3, internal tube 4, external tube 5 and brass pin 6.

Design examples Figure 5 shows the new apparatus in its entirety.

Claims

1. An adjustable apparatus for the fixation of loose parts under construction, especially surface treatment, comprising an adjustable holder which is mounted on a pair of wheels, characterised in that at least one turning mechanism with means for locking comprising at least two concentric tubes where the turning mechanism is surrounded and can be locked with a heat expanding pin bigger than the two concentric tubes, so that the apparatus can overcome heating without risking that the locking mechanism opens.

2. An adjustable apparatus according to claim 1, charac- terised in that the locking mechanism is connected to a holder for loose parts, which is an integrated part of the apparatus and where an adjustable support bar comprises an oval whole.

3. An adjustable apparatus according to claim 1 or 2, characterised in that it can be reduced in size because of its foldable rear leg.

4. An adjustable apparatus for the fixation of loose parts under construction substantially as hereinbefore described with reference to figures 4, 4.1, 4.2, 4.3 and 5 of the drawings.
