Description

Fitting scaffold

The subject of the invention relates to a fitting scaffold that contains legs, casters fitted to the lower end of the legs, bracing strutting and boards suitable for forming a horizontal access surface.

For the support of carrying out internal fitting work generally known ladders or other scaffolding are used. Both in the case of ladders and other supporting structures numerous versions are used.

The most widespread such device used in internal construction industry work is the ladder, which in general has a determined height. There are ladders that consist of several parts and their height can be adjusted in this way, or that can be opened along hinges in several parts, but all of them can be raised to a limited height.

Changing the position of ladders is very simple to carry out, and this is necessary because the distance that can be reached from a ladder - due to its structure - is no further than an arm's length.

Where it is necessary to carry out work over a larger area at one time ladder scaffolding or boarded trestles are used. In general the disadvantage of boarded trestles is that it is necessary to disassemble the whole structure in order to change position.

The rolling construction scaffold that can be known of from patent description registration number HU 214 496 makes easier position changing possible. The sides of the scaffold are formed by ladder-like frames which are connected to one another with bracing rods and the lower ends of all the frames are fixed to a frame that rolls on wheels. Boards that form a horizontal access surface can be placed on the steps of the ladder-like frame at different heights. Its disadvantage is partly due to that the ladder steps are at a relatively large distance from one another, and so the height of the boards can only be varied by the given unit, and partly due to that the access surface cannot be extended. The aim of the invention was the creation of a supporting structure for interior fitting work that makes it possible to create as large a horizontal access surface as possible at a very variable height. A further aim is that it should be simply assembled and easily moved.

The invention is based on the recognition that if steps with a determined side length are used, which steps are hung on horizontal rods with the help of hooks, and the horizontal rods are connected to vertical columns the height of which may be adjusted, then the set task may be solved. The idea of the invention also includes that the longer side of the steps is a whole multiple of the length of the shorter side, as is the distance between the horizontal rods of the height adjustments formed on the vertical columns.

The extension of the access surface according to our recognition is realised by that the steps with the size proportion as described can not only be positioned lined up one after the other, but at right angles also.

In the sense of the invention the set task has been solved with a fitting scaffold that contains legs, casters fitted to the lower end of the legs, bracing strutting and boards suitable for forming a horizontal access surface, and characteristic of which fitting scaffold is that the bracing strutting is formed by two vertical frames facing each other. The frames have horizontal rods and vertical rods, at the meeting points of the horizontal rods and the vertical rods there are fitting stubs standing out vertically from the plane of the frame. The frames are connected to one another via the connection elements connected to the fitting stubs, each and every frame has at least two horizontal rods, and favourably at least three, the boards are steps with hooks along their edges that can be hooked onto the connection elements and/or the horizontal rods, and the vertical rods of the legs and the frames are fixed to one another through the releasable connection elements that set the variable height of the legs.

In an advantageous construction form of the invention the connection element is formed by separate rods inserted between the fitting stubs of the frames, while in another case the connection element is a grid form inserted between the fitting stubs of the frames. A characteristic of the grid form may be that it contains horizontal members running as a continuation of and connected to the fitting stubs and one or more vertical members that strengthen these.

A further criterion of the invention is that the fitting stubs have fitting openings and the connection elements have connection openings. The fitting stubs and the connection elements are connected to one another through the releasable connection elements that are threaded through the fitting openings and the connection openings covered with them.

According to another construction example there are setting openings on the legs that set the height of the steps.

In a favourable construction form of the fitting scaffold the distance between the fitting stubs conforms to the distance measured between the setting openings, favourably so that it is a whole multiple of it.

It is practical, furthermore, for the vertical rods of the frames to have at least one positioning opening in the vicinity of their lower end.

In a version of the fitting scaffold according to the invention the horizontal rods of the frame, its vertical rods and fitting stubs, furthermore, the connection elements and the legs are made of closed section metal, and the legs are slid into the internal spaces of the closed section vertical rods.

From the point of view of the constructed form it is very favourable if the length of the longer side of the steps is a whole multiple of the length of the shorter side.

An advantage of the fitting scaffold according tot he invention is that due to its construction the optimum fitting height can be set in small steps and set easily, and also that the size of the horizontal surface can in practice be extended in all directions without restriction. In the following the invention is presented in detail in connection with a construction example on the basis of drawings. In the appended drawings

Figure 6 show the outline of the plan view of a possible arrangement of fitting scaffolds connected to one another.

Figure 1 illustrates the fitting scaffold according to the invention and its components. It can be seen that the frame 1 consists of horizontal rods 2 and vertical rods 5, as well as connection elements 3 positioned at right angles to these. The vertical rods 5 are connected to the legs 6 with the help of the connection element 14 placed in the setting opening 1 1 and, in accordance with this, in the positioning opening 10. In the construction example shown in the figure the step 15 is positioned on the uppermost separate rod 31 that forms the connection element 3 with the help of hooks 7.

The fitting stubs 4 at the meeting point of the vertical rods 5 and the horizontal rods 2 are shown in figure 2a. It can be seen that the fitting stubs 4 protrude out of the plane of the frame 1 at right angles, and a connection element 3 is positioned between two facing fitting stubs 4. In the depicted construction example the connection element 3 is formed by separate rods 31 in both ends of which there is a connection opening 12 formed. There is a fitting opening 31 in the vicinity of the free end of every fitting stub 4, which is covered by the connection opening 12 after the positioning of the separate rod 31. The separate rod 31 and the fitting stub 4 are fixed to one another via the releasable connection element 9 threaded through the connection opening 12 and the fitting opening 13.

Figure 2b depicts a construction form of the frame 1 where the frame 1 has 3 horizontal rods 2. It can be seen that at the meeting points of the horizontal rods 2 and the vertical rods 5 there are hollow section fitting stubs 4 - with a rectangular cross-section on this figure.

Figure 2c and 2d illustrate the hooks 7 positioned at the ends of the steps 15.

On figure 2e the setting openings 11 formed in the legs 6 can be seen, the distance between which is set so that it is a whole number quotient of the distance between the fitting stubs 4. Also shown on the drawing is the caster 8 connected to the leg 6, which aids the simple and safe repositioning of the fitting scaffold.

Figure 3a illustrates a construction example where the connection element 3 is formed by the grid form 32 shown on figure 3c. The grid form 32 is set up so that its horizontal members 32a are twice as long as the separate rod 31. A vertical member 32b is connected to the middle of the horizontal members 32a. Through the fact that the length of the horizontal member 32a is twice the length of the separate rod 31 between the vertical plane frames 1 positioned facing one another two steps 15 may be placed beside each other. Such an arrangement can be seen on figure 3b.

Figure 4a shows a case where the connection element 3 is formed by the grid form 32 shown on figure 4c. In this case the length of the horizontal member 32a is three times the length of the separate rod 31, and so the vertical members 32b are positioned so that the horizontal members 32 are divided into thirds. In this arrangement three steps can be placed next to one another, as is shown in figure 4b.

Figures 5a and 5b show how it is possible to connect two fitting scaffolds next to each other. On both figures the economic space utilisation can be seen. It can be seen that the step 15 can also be positioned between two scaffolds, as they are rigid enough to bridge over the given distance without support. On all of the fitting scaffolds shown on figure 5 a the steps 15 are positioned on the uppermost level of the frames 1.

Figure 5b shows an outline arrangement where the steps 15 are positioned at different levels, in other words they fall in the planes of horizontal rods 2 of different heights.

On figure 6 it can be seen well that the steps 15 can be positioned on the fitting scaffolds at right angles to one another and next to one another.

As the form of the steps 15 is such that the length of their longer side is a whole multiple of the length of their shorter side, practically twice the length, they may be placed at right angles to one another so that they form a regular shape in plan view.

The fitting scaffold according tot he invention can be advantageously applied in the case of all sorts of interior construction industry and other fitting work. The fitting scaffold provides safe support for carrying out work on both the horizontal and vertical plane in between floors.
