Abstract
Description
[0001] The invention relates to an auxiliary tool for door installation according to claim 1.
[0002] Doors mounted on hinges, especially interior doors, are typically attached using hinges. Hinges consist of two parts: the lower hinge and the upper hinge. The lower hinge is usually mounted to the door frame, while the upper hinge is attached to the door itself. Lighter doors are usually attached with just two hinges, spaced apart. Heavier doors often use three hinges. Removing a door, often called "taking it off its hinges," is generally straightforward. The door is simply lifted until the hinge parts separate and then set aside. Rehanging a door, however, is much more difficult. After lifting the door, the hinge parts must be precisely aligned before the door can be lowered into its operating position. This task becomes increasingly challenging with more hinges.If the door is hinged in a frame near a corner of the room, precisely aligning the hinge components can become a real test of patience. Heavy doors often require assistance. This person lifts the door and holds it in a raised position while the first person works on the adjustments. Occasionally, misalignment issues arise, further complicating the process of hanging the door.
[0003] The invention relates to an auxiliary tool for door installation that significantly simplifies this installation process. When using this auxiliary tool, it is generally not necessary to enlist an assistant for the door installation, as the installation process can easily be handled by a single person.
[0004] An advantageous embodiment of the invention is explained in more detail below with reference to the drawing.
[0005] This shows Fig. 1. A sketch illustrating the assembly process using the auxiliary tool; Fig. 2. A guide rail of the auxiliary tool in side view; . Fig. 3 a front view of the in Fig. 2 guide rail shown from the direction of arrow A; Fig. 4 a partial view of a guide rail.
[0006] Fig. Figure 1 shows, in a schematic representation, the use of the auxiliary tool 1 during the installation of a door 3, which is ready to be hung. Parts of the two-part door hinges are attached to the frame 2 on one side and to the door 3 on the other. Only the part of the frame 2 to which the door 3 is attached is shown. The door hinges can be, for example, mortise hinges or surface-mounted hinges. Typically, the lower hinges 2.1 and 2.2 of two door hinges are mounted on the fixed frame 2. The upper hinges 3.1 and 3.2 of the door hinges are mounted on the door 3. The auxiliary tool 1 includes a guide rail 1.1 or 1.2 for each door hinge. In this case, there are two guide rails for two door hinges. The guide rails 1.1 and 1.2 are connected to each other by at least two support elements 1.3 and 1.4. An advantage is that their spacing can be changed if necessary so that the guide rails 1.1 and 1.2 can be precisely aligned with the lower hinges 2.1 and 2.2 attached to the frame 2. The pins 2.1a and 2.2a, which are attached to the lower hinges 2.1 and 2.2 and project in sections, are designated as such. The upper hinges 3.1 and 3.2 of the door 3 are rotatably mounted on these pins. The auxiliary tool 1 also includes feet 1.5 and 1.6, on which the auxiliary tool 1 can be placed for the assembly process.
[0007] The following section explains the construction of guide rail 1.1 in detail. Any other guide rails that may be present are constructed analogously. Fig. Figure 2 shows, greatly enlarged, a side view of a guide rail, here guide rail 1.1. Fig. Figure 3 shows a view, in the direction of arrow A, of the head of the [unclear text]. Fig.Guide rail 1.1 shown in Figure 2. The guide rails 1.1 and 1.2 can preferably consist of an L-profile. A loop holder 1.1a extends perpendicular to the longitudinal axis of the guide rail 1.1 over a certain length, and an open loop 1.1b is attached to its free end at an angle of 90°. The opening of the loop 1.1b is designated by reference numeral 1.1c.
[0008] The following describes the assembly process for door 3 using auxiliary tool 1. Auxiliary tool 1 is positioned and adjusted in front of frame 2 such that the open eyelets on the head of each guide rail engage the pins 2.1a and 2.2a and rest at their base on the respective lower hinge 2.1 or 2.2. The height of the eyelet holder 1.1a is dimensioned such that, in this adjustment position of auxiliary tool 1, the head of each pin 2.1a or 2.2a protrudes slightly beyond the inner surface of the horizontal part of the guide rail. Door 3 is then slightly lifted and moved towards auxiliary tool 1 so that each upper hinge 3.1 and 3.2 rests on its respective guide rail 1.1 or 1.2. The door 3 is then moved towards the frame 2, with the upper hinges 3.1 and 3.2 sliding on their respective guide rails 1.1 and 1.2. After the upper hinges 3.1 and 3.2 engage...The upper hinges 3.1b and 3.2 are placed onto the heads of the pins 2.1a and 2.2a, which protrude only slightly. The upper and lower parts of the hinges are now optimally aligned, allowing the door 3 to be fully hung in a final assembly step. To do this, the auxiliary tool 1 is moved away from the frame 2, completely releasing the eyelet 1.1b from the pin 2.1a. The same applies to the second hinge. The upper hinges 3.1 and 3.2 can now easily lower themselves onto the pins 2.1a and 2.2a without any further effort from the installer, thus aligning the door 3 in its operating position.
