Description

FOLDING ROOF CHAIR

FIELD OF THE INVENTION

The invention relates to a folding roof chair / roof lattice as defined in the preamble of claim 1, hereinafter referred to as a folding roof chair.

BACKGROUND OF THE INVENTION

Prefabricated roof chairs are transported to the construction site completely assembled in an upright position, whereby the transport height is high and in practice the transport equipment must be specifically designed for transporting the roof chairs. This increases the cost of transportation. In addition, construction on site is difficult due to the large size. The folding roof chair structure reduces these disadvantages.

Delivering houses and buildings as complete or as complete modules as possible is becoming increasingly common. The folding roof chair even allows for a finished roof at house factories as it does not significantly increase the transport height. The solution also achieves rapid "weather protection" construction and clear cost savings when roofing can be completed in factory conditions.

LIST OF FIGURES

In the following, the invention will be described in detail with reference to the accompanying drawings, in which Figure 1 shows the shape of a folding roof chair when installed. Figure 2 shows the installation step of a folding roof chair, showing the movement paths of the articulated parts. Figure 3 shows a folding roof chair assembled from the numbered parts of Figure 1 in the packing and transport position. The pictures are shown in cross-sectional view relative to the roof ridge.

DETAILED DESCRIPTION OF THE INVENTION

Figures 1 to 3 show a folding roof chair according to the invention and its various operating principles. Figure 1 shows the part numbers used in the invention, which are referred to in the description below.

Reinforced holes (9) are drilled in the upper chord (1) for attaching the vertical supports (2, 4), the inclined support (5) and the brush piece (6). A reinforced hole (9) is drilled in the upright support (4) at the upper end and at both ends of the upright support (2). The reinforced holes (9) are drilled at both ends in the oblique support (5) and the brush piece (6).

The diagonal support is fixed at the same position at its upper end as the vertical support (2). The lower end of the tilt support is attached to the lower end of the vertical support (4). The brush body (6) links the upper ends to each other, if the transport length allows it. The lower end of the oblique support (5) is attached to the lower end of the upright support (4) during installation on a construction site. The bolts (8) are used for fastening.

Each component attachment has a joint (7) which enables the folding roof chair of Figures 1-3 to function. The holes in the joints (7) are reinforced. Tighten / lock the joint points in the case of a bolt joint.

At the construction site, the folding roof chair is raised (or completely finished ceiling) to the ridge height (Figure 1), whereby the vertical and inclined supports can be folded down and secured to the structures below, determined by the timber structure designer. The eaves (3) are shaped as desired.

Claims (3)

PROTECTION OF CLAIM Folding roof chair with at least one upper pole (1), characterized in that the vertical supports (2,4), the brush piece (6) and the inclined support (5) are hinged to the upper pole (1) by means of a bolt (8). Reinforced holes (9) are drilled into the joints (7) according to the diameter of the bolts (8) used. The dimensions of the vertical supports (2,4), the ridge piece (6), the upper chord (1) and the cantilever (5) and the reinforced holes (9) drilled thereon are dimensioned so that the folding roof chair can be folded horizontally to the ridge height and vice versa ) through the bolts (8) installed, without removing the mat. SKYDDSKRAV 1. Hopfällbar takstol som uppvisar åtminstone et högben (1), kännetecknad av att stödben (2, 4), nockstycke (6) och en sträva (5) har ledat på högbenet (1) med en bult (8), förstärkta hål (9) har borrats i leder (7) en diamtern på de bultar (8) som ska användas, dimensionerna av stödbenen (2, 4), nockstycket (6), högbenet (1) och strävan (5) samt platserna för de förstärkta hole (9) which borrats i dem har dimensioned such that it hopfällbara takstolen kan Fallas out from the horizontal position läge made up to taknocken Science tvärtom utan att de loss of bolts (8) which de förstärkta installerats through holes (9).
