AI Technical Summary
Existing insect screen door mounting aids are inadequate for precise and stable installation, particularly on uneven surfaces, often requiring multiple hands and leading to improper leveling and frequent tipping.
A rectangular aluminum tube with adjustable feet and a spirit level, combined with a non-slip rubber and felt-covered angle bracket, allows for precise leveling and single-person installation of insect screen doors.
Enables quick, accurate, and stable installation of insect screen doors on uneven surfaces, reducing installation time and eliminating the need for multiple workers.

Abstract
Description
1. Scope of application of the invention
[0001] The application area of the invention is the professional installation of insect screen hinged and swing doors in both private and commercial settings. 2. Known state of the art
[0002] Common mounting aids for insect screen doors consist of just two separately height-adjustable aluminum feet. These only partially simplify the installation of insect screen doors, as the feet often tip over, making proper leveling of the doors difficult. Furthermore, these feet are frequently designed by the manufacturer specifically for swing doors (see mounting feet from MHZ).
[0003] Often, the surface – due to the paving stones on the patio – is uneven. Because of their narrow design, the feet don't have a good grip here. This often makes them difficult to position and requires several hands. 3. Objective of the invention
[0004] The aim of my invention is to provide an assembly aid that enables the quick and precise alignment of insect screen hinged and swing doors by a single person. Incorrect positioning is prevented. 4. Solution approach and technical features of the invention. How is the invention structured and how does it function?
[0005] My assembly aid essentially consists of a rectangular aluminum tube with an attached aluminum angle bracket and two height-adjustable and laterally tiltable feet (each 120 mm long). These can be adjusted manually or mechanically using a cordless screwdriver via the integrated Allen key adapter.
[0006] The small built-in spirit level allows for precise leveling.
[0007] The feet are equipped with a non-slip rubber, and the angle rail is covered with felt to prevent scratches on the insect screen door.
[0008] The mounting aid is placed on the floor in front of the door where the insect screen door is to be attached. The insect screen door is then placed on the attached angle bracket. The mounting aid is then adjusted to the correct height using the two feet, either by hand or with a power drill. The integrated spirit level indicates whether the door is level. Lateral adjustments are easily made by sliding the door left or right along the felt pad, preventing scratches. Once the door is correctly positioned, it can be screwed or glued in place with just one hand. b. Which technical features are significantly new compared to the state of the art?
[0009] My invention connects the two height-adjustable feet into a single unit using the aluminum tube. 5. Advantages of the invention compared to the prior art. Technical
[0010] The mounting aid, with its combination of two feet and rail, allows for stable positioning in both height and width. The spirit level makes it easy to check the level of the insect screen door. b. From a business management perspective
[0011] The mounting aid enables quick and accurate positioning of the insect screen door. Work can be carried out faster and more efficiently. Furthermore, installation by just one person is possible, as the mounting feet, and consequently the insect screen itself, are prevented from tipping or falling over. I believe this mounting aid can significantly reduce the installation time of an insect screen door. It also eliminates the need for a second worker. 6.

Claims
[1] The mounting aid for an insect screen door includes an elongated guide element that can be positioned along a door frame. [2] The mounting aid for an insect screen door includes at least two stepless height adjustments arranged on it for temporarily locking the guide element in front of the door frame. [3] The assembly aid for an insect screen door includes the fact that the elongated guide element and the continuously adjustable height adjustments form a unit. [4] The assembly aid for an insect screen door includes at least one receiving device for holding an insect screen door profile in the correct position during assembly. [5] The assembly aid for an insect screen door is characterized by , that the receiving device specifies a defined mounting position relative to the door frame, so that the door profile can be fixed in the correct final position without manual alignment. [6] The assembly aid is characterized by , that the guide element can be adjusted as a rail-shaped profile with at least two continuously adjustable height adjustments by hand or - due to hexagonal adapters - by machine. [7] The assembly aid according to one of the preceding claims, characterized by that the receiving device has an L-shaped contour that is adapted to the geometry of the insect screen door profile. [8] The assembly aid according to one of the preceding claims, characterized by that the mounting aid is designed in such a way that it does not cause any damage to the insect screen profile through the application of felt. [9] The assembly aid according to one of the preceding claims, characterized by that the guide element is equipped with a spirit level or bubble that allows for horizontal positioning. [10] The assembly aid according to one of the preceding claims, characterized bythat the assembly aid is designed in such a way that it can be removed from the door frame without leaving any residue after assembly is complete. [11] The assembly aid according to one of the preceding claims, characterized by , that the assembly aid is designed in such a way that it is non-slip due to the application of rubber to the continuously adjustable height adjustments.
