DESCRIPTION:
BRIEF SUMMARY
The invention relates to a stationary roll type awning such as that of applicant's U.S. Pat. No. 4,469,159, with central fixing section with a housing with an inner space with an approximately circular cross-section to accommodate a cloth shaft and with a central supporting element which forms at least one part of the housing. Such an awning is known from DE-A-21 07 477, for example. This awning possesses a sturdy box which accommodates the cloth roll and on which a U-shaped rail is mounted containing the swivel arms and which can be swiveled forward by 90.degree..
An awning with a central web as a central supporting element is known from U.S. Pat. No. 4,469,159 of the applicant, whereby the housing accommodating the cloth roll with cloth shaft possesses a square cross-section. This narrow central web supports one bearing pedestal in each case at its top and bottom ends to accommodate one horizontal articulated shaft in each case for mobile fixing of individual parts. Furthermore, an awning with a tubular housing with an inner space with approximately circular cross-section to accommodate a cloth shaft is known from DE-A-26 20 112, whereby the housing is held by two brackets. In addition, an awning with a housing for the cloth roll with circular cross-section is known from DE-OS 25 14 941. However, a continuous supporting element, supporting tube or supporting rail serving the purpose of reliable and movable fixing of the brackets and arm fixing elements is missing. The housing itself is not suitable to absorb any forces.
In all previously known designs, the dimensions transverse to the longitudinal direction were always too large, in spite of all design efforts. It cannot be overlooked, however, that the whole swivel mechanism must be particulary sturdy and above all torsionally rigid for the forces required to extend and retract the awning, particularly with the weight of the awning material, the articulated and swivel arms and, specially for safety reasons, owing to the strength with respect to wind load required by authorities as well as owing to resistance to wear. This alone places certain limits on reduction of the dimensions.
On the other hand, however, the design must be such that it can be realized for the widest possible variety of length dimensions without changes to the design principle.
In particular, one must demand that the awning be able to be adapted to the widest possible range of distances between fixing points without extensive and difficult reworking on-site. Admittedly, these are demands which initially appeared completely opposed to a light-weight design.
However, the invention has set itself the task of creating an awning of the type mentioned above with which these inherently contradictory demands can be satisfied in an astonishingly simple manner. This is achieved in the invention by the fact that at least one continuous open chamber with guide strips or stop strips is provided on the outer side of the central supporting element and that reinforcement sections which can be slid into this chamber are provided which are used at the same time indirectly or directly to secure the bearing pedestals for the swivel arms, tilt limiters, gear parts or as a coupling, thus reinforcing the whole construction, whereby these reinforcement sections possess one or more closed and/or open chambers. The arrangement should preferably be such that the reinforcement sections possess an open chamber to accommodate fixing means and at least one further closed chamber in a center section.
It is particularly advantageous that the bearing pedestals for the swivel arms are secured on the one hand by means of bolts and nuts in a continuous groove on the bottom end of the central supporting element and, on the other, by means of fixing means at the reinforcement sections.
Tilt limiters or a drive for awning adjustment can also be secured in the same way.
Refer to the other individual claims for further embodiments of the invention.
The invention will now be described in more detail in conjunction with the en
