DESCRIPTION:
BRIEF SUMMARY
The invention relates to a curtain, more particularly a window shade, with guiding and deflecting elements fitted to the curtain fabric for the drawing cords, in which the curtain fabric carrying attachment plates with rings and eyes is fastened with the aid of an adhesive closing tape to a mounting track rigidly anchored in the building.
BACKGROUND OF THE INVENTION
From the DE 37 14 105, a window shade with guiding and defelcting elements for the drawing cords attached to the curtain fabric is known, in which each deflecting element is comprised of an attachment plate connected to the curtain fabric , which, by preference, is integrally and rigidly connected with a guiding eye hanging down from the latter. The curtain material supporting the attachment plate with the eye is secured with the aid of a textile adhesive closing tape. Consequently, the shade is fixed on the mounting track with the aid of an adhesive closing tape comprising a fleece tape and a Velcro fastener tape. The attachment plates with the eaye for the drawing cords are in this case on a portion--fleece tape or Velcro fastener tape--of the adhesive closing tape which, in turn, is brought into adhesive connection with the other portion that is secured to the mounting track. However, this constructional design can only be employed with lightweight curtain fabrics. When heavy curtain material is used, the tensile load given rise to by the great weight acts upon the adhesive connection with the result that, on account of the strong traction, the fleece tape becomes detached from the Velcro fastener tape of the adhesive closing tape.
The technical problem of the present invention is to provide, in a curtain or shade of the type stated in the beginning, an attachment in which also use is made of an adhesive closing tape for heavy curtain fabrics, wherein the tensile forces given rise to by the weight of the shade do not act upon the adhesive closing tape, but are conducted into the mounting system on the building.
This technical problem is resolved by the features characterized in the Claim 1.
SUMMARY OF THE INVENTION
According to this the invention consists in that the attachment plates for the production of a frictional operative connection with the mounting track anchored in the building are connected via detachable supporting and connecting elements absorbing vertical tensile loads.
These supporting and connecting elements are comprised of a horizontally proceeding web attached to or formed onto each attachment plate and of an engagement groove formed on the attachment plate and of an engagement groove formed on the mounting track and proceeding in the longitudinal direction of the mounting track for the webs of the attachment plates. By means of the engagement of the webs of the attachment plates into the engagement groove on the mounting track, a frictional connection is provided and the tensile loads otherwise acting upon the adhesive closing tape are conducted via the supporting and connecting elements into the mounting track and thus absorbed by the wall of the building on which the mounting track is anchored. In this way an inadvertent detachment of the adhesive closing tape is avoided since the tensile loads or forces given rise to by the weight of the curtain or shade are no longer conducted into the adhesive closing tape. Consequently, no tensile load acts upon the adhesive closing tape any longer.
Advantageous constructions of the invention are characterized in the subclaims.
Here the constructional design of the mounting track is especially advantageous, which possesses a web-like cross-sectional configuration that is comprised of a first channel section with horizontally proceeding legs and of a web interconnecting the latter, in which case the upper horizontal leg is carried with one section beyond the leg connecting web and the free ends of the legs possess angled sections facing one another, and of a second section proceeding parallel to the first section, formed onto the free end of the lower leg of the first channel s
