Abstract

The adhesive hook has a base plate (1) with a self-adhesive mass (2) on the rear side. The front side of the base plate has a holder (3) to fit and remove an inserted plate. The base plate fits into an opening in the fly screen, and the plate is over the fly screen at least where the opening is used.

Description

The invention relates to an adhesive hook for mosquito nets or the like. as well as his Use, in particular an adhesive hook for attaching a Fly screens on a building opening, e.g. a window or a door. A Woven or a knitted fabric with 4 eyelets in particular in the corners can be used with the Adhesive hooks can be securely attached in front of or behind a window. The outer Hook shape and the eyelet shape in the woven or knitted fabric or base plate and Eyelets are coordinated and fit together exactly. A additional attachment plate fixes the knitted eyelet securely on the glued hook or the base plate.

The attachment is particularly suitable for elastic knitted fabrics. Due to the high restoring forces of elastic tulle fabrics, e.g. based on Elastan®, are the mushroom tapes used today for secure fixation only suitable to a limited extent.

Advantages:

No special fabrics or knitted fabrics are required. A Fixing with a mushroom tape always requires an adjustment of the number of stitches / Mesh size to the corresponding mushroom band to secure fixation to reach.

The simple fixation of a fly screen with 4 hooks allows as often as you want quick assembly / disassembly of the system. Conventional fly screens must first be removed from the mushroom belt. This process cannot be arbitrary Repeated often, since each peeling process is mostly irreparable Tissue or knitted fabric damage.

State of the art

Known systems for attaching fly screens are e.g.

Fly screen with mushroom band attachment - disadvantages

• A quick removal / assembly of a fly screen is not possible because the tulle is first detached from the mushroom ribbon / linked to the mushroom ribbon got to.
• The knitted or woven quality of the tulle must be on the mushroom ribbon structure be coordinated, otherwise there will be insufficient connection strength is guaranteed.
• Swing roof windows with a pivot point in the middle can be installed after a conventional fly screens can no longer be opened.
• If not carefully applied, wrinkles will form in the grille, which causes an unclean, unsightly appearance.
• An elastic fly screen, such as for windows with thighs cannot be securely fixed with a mushroom tape. The restoring forces of the elastic tulle can detach from the mushroom band cause.
• Mushroom tapes leave behind after removing them from the window frame often residues of adhesive. These are difficult to remove due to the difficult to access place of glue in the window frame profile.

DE 296 13 763 - disadvantages

• Irreparable damage to the window frame or the surrounding wall by using hooks or holding pins with screws or Nails
• Need to use dowels on a plaster base.
• Delicate knitted or woven fabrics can be damaged.
• No tight seal between the screen edge and wall.
