ABSTRACT:
FIELD OF THE INVENTION
The purpose of the invention consists of two improvements included in the construction of mechanical draft excluders for the lower part of jambs.
BACKGROUND OF THE INVENTION
Draft excluders are known for blocking the passage of air between the edge of a door and the ground, from those which function statically to those which, being elevated during the movement of the door, automatically descend to close them.
Specifically, the invention's improvements are related to elevated automatically-descending draft excluders.
The aforementioned automatic draft excluders, when they are installed, have the problem that the elongated elements that comprise them must be cut according to the measurements of the door where they are going to be placed and adapted to it, which requires the purchaser of the draft excluder to go to a specialized draft excluder installer, since he is unable to install it himself.
SUMMARY OF THE INVENTION
The improvements covered by the invention have been created to facilitate the work of installing the draft excluder by the non-specialist user.
With these improvements, a user who wishes to install the draft excluder himself is not required to saw or cut any of the parts that comprise the body of the draft excluder, given that it has the advantage that it can include a wide range of door widths and the user only has to regulate and fix the width according to the width of the door where it must be installed.
Thus the improvements allow the user to purchase the draft excluder in the form of a kit with all the elements required for its custom installation, following simple installation instructions. It is obvious that the user will thereby avoid having to call an expert installer to install the draft excluder, thereby saving the money and also gaining the satisfaction of having performed the installation himself.
