The hiring concerns a push handle plate for doors »

Known are push handle plates made of a thermoplastic high-grade synthetic resin, » Such push handle plates are cut from extruded plates and manually by breaking the edges, finishing, Polishing and the like finished, = threaded sockets for fastening the push grip plates are also inserted by hand » Such panels have insufficient impact and scratch resistance. They are very temperature-sensitive, so that they can be accidentally touched with a match or a other flames can be damaged «The panels are sensitive to chemical influences, especially when they come into contact with aggressive ones Substances., Under the influence of the weather, the panels become dull and unsightly., Dirt particles easily adhere on the plates «Solehe - comparatively thick (up to 20mm thick) Push grip plates cannot be manufactured as injection molded parts, since with such great material thicknesses a homogeneous one can be achieved Condition of the injection molded part is not possible. The known

As a result of the production described above, push grip plates are extremely expensive ₅ and are not satisfactory in use.

The task of the innovation is to create a comparatively cheap and with simple manufacturing technology to produce push grip plate.

This' object is according to the! ₅ control achieved in that the pull handle plate is formed as a solid thermoset presser "

Although the production of such thick thermoset molded parts is more uniform Texture j high surface quality and. In the form of a comparatively thick, flat panel due to the expected flow structures and shrinkage phenomena as practically impossible appears, the innovation shows a way to circumvent these difficulties,

Surprisingly, through suitable control of the pressing process, gate heating and pre-pressing stages known per se can be used Manufacture thermoset molded parts of the desired thickness up to 25mm, which meet all quality requirements in terms of uniformity, Right angles, dimensional accuracy, surface quality, durability against chemical and mechanical influences, scratch resistance, temperature

_ χ - ■

temperature resistance _s Fulfilling the full extent of weathering resistance »After the pressing process, all that is required is post-treatment by polishing =

Leave threaded bushings for fastening the pull handle plate Press in in a manner known per se »The threaded bushes sit exactly true to size and evenly in all panels, since the shrinkage sizes are precisely "taken into account" when the mold is made be-can.

Windows and inserts can be molded into the mold immediately during the pressing process using appropriate measures. By designing the mold, any desired surface structure can be created, including a plastic surface pattern. received _? without additional manual post-processing being necessary »

Details of the innovation are explained on the basis of some exemplary embodiments with reference to the attached drawing, It represent σ

Figure 1 is a rear view of a first embodiment a push handle plate according to the innovation,

, Figure 2 is a rear view of a pull handle plate with Window cutout after the innovation,

Figure 3 is a front view of a pull handle plate with an insert,

FIG. 4 shows a section along the line IV-IY in FIG. 3,

Figure 5 shows a section for a modified training according to the line V-V in Figure 3,

Figure 6 is a front view of a pull handle plate a plastic surface pattern and

Figure 7 a section along the line VII-VIl in Figure 6 *

In the simplest case, the pull handle plate 1 is formed according to the Heuerung Figure 1 as parallelepiped "The size may be chosen to be different, it differs depending on the wishes of the customer ο The thickness of the butt grip plate lies in a range Zairian 10 and 25mm" FIG Λ shows a rear view of the handle plate ₅ in which several threaded sockets 2 are inserted, which are used to attach the handle plate to a support part. The front of this bumper plate is flat and, for example _, smooth. One can of course also provide a roughened, corrugated, grained, grooved or otherwise designed surface

The push grip plate according to FIG. 1 is a thermoset molded part. Uniform and homogeneous texture with precisely right-angled edges and a flat surface »By preheating and pre-pressing a homogeneous and: uniform structure of the Finished pressed part »Flow structures are in the finished pressed part not recognizable »You get a uniform and smooth Surface. The edges are sharp or broken, depending on the design of the shape and the desired design Training ,, The threaded sockets 2 are in the Staßgrippeplatte

pressed in immediately ,, This press-in technique is in itself known The push handle plate is after molding substantially ready for use »A simple reworking by deburring is sufficient the edges and polishing the surface, ■

FIG. 2 shows a further embodiment of a push grip plate 1 with a window cutout 3 ° The same is made by a corresponding insert of the mold directly during the pressing process manufactured so that a subsequent incorporation of such a window from the cut is not necessary »

In a further development of the innovation, insert parts of any type can be provided on the front of a push grip plate. Figures 3 to 5 show a corresponding Kaumf-ornu Figure 3 shows a front view of a push handle plate 1 · with a plate-shaped insert 4. This can be a metal plate, the surface of which is glossy or matt. In particular, an aluminum plate can be provided. The surface can also be anodized. According to the suggestion of the firing, the side surfaces 5 of the insert 4 run divergent from the front. Figure 4 · »The insert 4 is pressed directly into the push handle plate 1 'during the pressing process and sits firmly in the finished pressed part due to the divergent side surfaces 5» According to a modified proposal of the innovation according to FIG Provide support surfaces 7 »In this case, a plate-shaped insert 4" is subsequently inserted into the hemstitch Λ ^!. ' inserted and cemented, for example =

The furnace allows "any plastic design of the pull handle plate by appropriate design of the example ,, ο shape can be according to Figures 6 and 7 a plastic surface pattern on the top side of the pull handle plate 1" 8 -vorsehen in star shape. This surface pattern forms part of the pressed part.

The surface of the push grip plate can have any structure have what can be achieved by appropriate design of the mold plates,

The furnace thus provides a push handle plate, which is essentially produced in one operation »The considerable difficulties in producing a .thicken Press plate j die.Application of pressing technology for production make such push grip plates appear unsuitable, are overcome by the measures described «After the increase in prices, precise dimensional accuracy of the threaded bushes is achieved, which is a necessary prerequisite for attaching the push grip plates o leave the push grip plates after the innovation in terms of shape (rectangular shape, trapezoidal shape, diamond shape, curvilinear or circular delimitation) as desired, since. the respective mold can easily be designed accordingly. Plastic surface patterns as well as inserts can also be achieved in a large variety without difficulty.
