Description

Technical area

The present invention relates to a device and a method for attaching attachment elements, in particular an insect / particle protection grille or an insect / particle protection door, to on-site frame systems, preferably for windows and doors.

State of the art

Such devices are known in various designs and mainly the profile shape used or the particular system used to be attached to the insect screens or insect screens adapted. In essence, insect screens are attached to windows with brackets, brackets, bow springs, or a combination thereof. Insect protection doors are essentially fastened in such a way that hinge segments are screwed to the on-site door frame, masonry or other on-site objects and the protective door is hung on it. This will damage the on-site elements.

To avoid damage revealed DE 10 2004 002 573 A1 a holding element, which causes a detachable connection between the frame system and the attachment element, in which both are embraced by a bracket U-shaped. In order to use the holding element at different frame thicknesses, it is proposed to provide the frame-side U of the holding element with a latching element, so that the holding element is adaptable to the respective frame width.

The disadvantage here is that the locking element is relatively expensive to manufacture and is subject to wear when the attachment element is mounted and released.

Further disclosed DE 10 2004 002 573 A1 a holding element that is made of wire. It comprises a surrounding area, which comprises a web on a top element, and two retaining legs with retaining tabs at their ends, which serve to undercut the frame element. The retaining legs are resiliently rotatable relative to the Umfassungsbereich and clamp in this way the attachment element against the frame member. As a supplement to this embodiment proposes the additional application DE 10 2004 054 209 A1 to DE 10 2004 002 573 A1 to provide a releasable support member for holding a support frame for example, fly screens on a support frame, in which the support member is also made of bent wire, but has only one support leg. Furthermore, the holding connection is provided with the attachment element in the interior of the same over a flat support, which is achieved by waveform of this holding portion. The embodiments of wire has the disadvantage that only a small width variability of the holding frame can be operated, otherwise no sufficient spring clamping force can be ensured. Furthermore, the holding force can not be varied.

Presentation of the invention

The present invention is based on the object to provide an apparatus and a method, with which it is possible to provide a mounting option with which the on-site elements are not damaged, the attachment is preferably boring at the same time but easy to carry out, said the Obstructing a drilling is eliminated. It should be given sufficient support and disassembly should also be possible without much effort. Furthermore, it should be possible to use both insect screen doors and insect screen frames, and also window frames and door frames. Of course, these systems can also be used for particle protection such as pollen protection, dust protection. With the device, it should also be possible to provide a connection with different frame widths and different frame cross-sections, including in rounded frame profiles with a constant holding force.

This object is achieved by the features mentioned in claim 1 and claim 11.

An advantage of the embodiment according to claim 1 and 12 is that the fastening device is arranged on the on-site profile releasably without damaging the window or door frame profile and at the same time by the clamping force sufficient attachment is generated. Furthermore, different wall thicknesses are recorded with a single component. Due to the force-like clamping element a large variability is given. A continuous adjustment to all frame thicknesses and frame cross sections is thus possible.

Advantageous embodiments of the invention are characterized in the subclaims.

By the embodiments mentioned in claim 2 to claim 8, a fastening device is produced inexpensively in a simple manner, which is particularly well suited to produce the sufficient holding forces.

By mentioned in claim 9 embodiment can be used particularly well behind the on-site profile, whereby the clamping force can be well transferred and at the same time the function of the on-site profile as a door or window is not disturbed.

By the mentioned in claim 10 embodiment can be closed between a frame and top frame existing gap in a simple manner. This gap may be due to the frame geometry (round or bevelled outer edge). In non-rounded or beveled frame sections, a small gap can also be achieved by the top frame covering just exactly the inner circumference of the frame with its outer edge, and by the incident from the outside through the gap light when viewed from the interior of the room to a sufficient classified insect repellent effect. It is thus possible to produce an optimal clamping force on this frame. At the same time an insect-tight attachment is possible, since in this way any existing gaps are bridged.

Due to the embodiment mentioned in claim 11, it is possible to have available only a device for attaching doors, since these can be used on both sides. To provide a mirrored second embodiment is not necessary.

An advantage of the embodiment according to claim 13 to 15 is that a clamping force is easily generated and acts by a sufficient transfer in the optimum effective direction of the profile of the attachment element and the on-site frame system.

Figs. 16 and 17 show a fourth embodiment and Fig. 18 shows a fifth embodiment. A sixth embodiment is illustrated in FIGS. 19 to 23, a seventh embodiment in FIGS. 24a to 27, and an eighth embodiment in FIGS. 28 to 34. Variants of mounting options, applications and variants of the mechanical function and the arrangement of the embodiments are shown in the remaining figures.

A first embodiment of the fastening device 1 according to the invention, consisting of a carrier 2, a threaded spindle 3, a carriage 4, a lever arm 5, a second lever arm 6 and a bracket 7, is shown in Fig. 1 in a perspective view. The items are rotatably connected to each other at the pivot points A, B, C and D. The threaded spindle 3 is rotatably mounted in a perforation 10 in the carrier 2 and equipped at both ends with a slot 9, for example, standard screwdriver. Here also a Phillips or Allen recess can be provided for correspondingly different tools. The carrier 2 is additionally provided with two holes 8, via which the structure is fastened by screwing according to the invention. The fastening takes place via arranged at the ends of the support 2 angle plates whose lying in the plane formed by the carrier 2 legs have at least one perforation 8. If several holes are provided, then they can be arranged offset from one another. Also can be attached to other elements, for. As hinges or their hinge body, which also has the possibility that the hinge parts are attached at a later date.

Fig. 2 shows the individual parts of the fastening device of Fig. 1 as an exploded view in perspective view. In addition, the carrier 2 is shown as a sheet metal stamping 2 'before bending. The carriage 4 is equipped with a spindle 3 complementary internal thread 11.

Fig. 3 shows the working principle of the fastening device. By turning the spindle 3 (bow arrow), the carriage 4 is transported forward or backward in the direction of the arrow. The carriage 4 takes over the connection D with the lever arm 6 and this tilts the lever arm 5 about the pivot point A. In this case, the bracket 7 is moved in the arrow direction and the distance X between the support base plate 2 and bracket 7 decreases or increases. The bracket 7 is rotatably mounted to adapt to the later edition.

Here, instead of the rotatable threaded spindle 3 a, e.g. cylindrical shaft or rod 16 introduced over which a coil spring 17 is pushed. In the exemplary embodiment, a compression spring is advantageously selected. By pulling on the bracket 7 in the arrow direction is pushed over the lever arms 5, 6 of the carriage 4 in the arrow direction and the spring 17 is tensioned. If the bracket 7 is released, the spring 17 expands, pushes the carriage 4 back and the bracket 7 moves in opposite directions. A clamping force is created between the region X by spring tension and thereby a clamping effect in the assembled state. When using a tension spring, the principle works in reverse.

FIGS. 6 and 7 show a fastening variant of the device on a profile 14 (sectional representation) of an insect or particle protection frame. For this purpose, the device is connected by means of the screws 12 by a piping 13 which is inserted into a welt channel 14 of the profile 14 with the profile 14. Such piping 13 are primarily made of plastic or rubber. With you by pinching an insect screen on a frame (part) as a frame element 15 or

Frame element portion of a door or window 20 o. Ä. attached. For ease of positioning and guiding the screws 12, the piping 13 is provided with a keyway 13 in the embodiment. Due to the material of the welt 13 does not have to be pre-drilled for screwing the screw 12. By screwing the screw 12, the piping material is displaced and pressed against the wall of the profile 14. The screws 12 are virtually pegged with the profile 14 and the connection holds securely.

Fig. 8 shows the clamping of the fastening device 1 to an on-site frame member 15, for example. A window or a door. By turning the threaded spindle 3 with a screwdriver in the arrow direction, the combination profile section 14 and fastening device 1 is clamped to the frame member 15.

FIG. 9 shows the device of FIG. 10 clamped to a frame section, but with a wider frame element 15.

Fig. 10 shows the fastening device 1 according to the preceding embodiment. The device is mounted on a profile 14 as described in FIGS. 6 and 7. The profile 14 is additionally equipped with a component 18 which is e.g. is inserted by insertion in a cavity 19 of the profile 14. In the example shown, this component 18 is a hinge connection segment with which the hinge counterpart of an insect screen door is later connected. The combination profile 14, hinge connection segment 18 and the fastening device 1 according to the invention form a "mounting unit", which is attached according to the invention on-site, in which it is like a screw, z. B. to an existing door frame, is clamped. To this clamped "mounting unit" can then be e.g. an insect screen door are attached. In this case, the profile section 14 is correspondingly longer. By means of a plurality of hinge connection segments (preferably three), a plurality of profile sections (preferably two), preferably in length of the door height, plugged together and secured at several points with the fastening device according to the invention on site. Likewise, the fastening device 1 may be attached to a plurality of points on a bug guard frame and this so on an on-site window frame o. Ä. be attached.

Fig. 11 shows the attachment to an on-site door frame 20th

Fig. 12 shows a variant as a connection between the fastening device 1 and profile 14. In this case, a manufactured adapter element 21 is inserted into the piping channel 22 and screwed therein with screws 12 '. The adapter element has a kederförmiges insert element 21 '. On this adapter is then, as can be seen in Fig. 13, the fastening device 1 is screwed. In this embodiment, the carrier 2 is bent differently.

FIGS. 14 and 15 show a further developed variant of the fastening technique. Here, the fastening device 1 is connected instead of a profile 14 with an adapter piece 23. This adapter piece 23 may be formed differently, for. B. as a hinge connection segment. In this variant, the bracket 7 would be rotated by 180 °. This combination, as can be seen in FIG. 15, surrounds the on-site frame element 15. In forming the adapter 23 as a hinge connection segment, several, preferably three, of these combinations are used and the insect screen door is hung thereon.

Fig. 16 shows a mechanical variant of the fastening device 1, in which the lever arm 5 is moved with the carriage 4 and the lever arm 6 is fixed to the carrier 2. Fig. 17 shows a variant of the embodiment of FIG. 16, in which the bracket 7 is a separate part, which is hooked into the device in a perforation 8 '. Such a variant may, especially when attaching an insect screen frame to a window, bring with it advantages in handling. It is also shown that the bracket 7, 7 'can be formed differently.

Fig. 18 shows another mechanical variant. Here are the lever arms 5'u. 6 'e.g. the same length and the bracket 7 "is centrally positioned and designed as a rotatable pin.

Fig. 19 shows a further embodiment of the fastening device according to the invention 1. In this case, the lever arm 5, the second lever arm 6 and the bracket 7 from the carrier 2 in the opposite direction as shown in FIG. 1 are arranged. A hinge connection segment 24 is attached via one of the two bores 8 by inserting a screw 12 "into the bore 8 and screwing it to the connection segment 24. Fig. 20 shows the connected state between the fastening element 1 and the Terminal segment 24. Fig. 21 shows the arrangement of this on a frame 20, a door or a window. About the fastening device 1, a diaphragm 25 is arranged after the jamming with the frame part 15 (see Fig. 22). In a connecting pin 29, a hinge rotary member 26 is used (see Fig. 23) that is connectable to the profile 14 of the grid, whereby the grid is rotatably mounted on the frame 20. In this embodiment, it is not necessary to make a drilled connection between frame 20 and fastening device 1 or between profile 14 and fastening device 1.

Figures 24a to 24c show three special placement problems that may occur with certain frame shapes of doors or windows. In Fig. 24a left remains a gap 30 between the frame and fastening device 1, can pass through the insects. In Fig. 24b left of the frame is designed obliquely, which difficulties in the attachment of the fastening device 1 may occur because no sufficient clamping force can be generated because no sufficient abutment for the fastening device 1 is available. The same applies to Fig. 24c, in which the frame is executed rounded. These problems are solved with a further embodiment of the fastening device 1 'according to the invention as shown in FIGS. 25 to 34. Schematically, the solution is already shown in the respective right representations of Fig. 24a to 24c.
