Description

The present invention relates to a clamping device according to the preamble of the main claim. The terms clamping device and clamping hinge are used synonymously. Clamp hinges have long been known for a wide variety of applications. They play a major role for insect, pollen and / or particle protection screens, sun protection fabrics, pleated blinds, because they eliminate the need for time-consuming drilling, screwing and the associated damage to window frames, door frames, jambs, etc., which is essential, especially for the use of such systems in rented apartments. The clamping hinges used in the prior art are generally only suitable for specific applications, for example, when intended solely as door hinges into which insect screen frame systems are then hung. These clamping hinges are not suitable for other uses. Even for this specific application, such as a clamping door hinge, different hinge designs are required, depending on whether the clamping hinge is to be mounted top left / bottom right, top right / bottom left, or in the center of a door or window frame. Furthermore, the hinges are limited to specific frame thicknesses. This may necessitate the use of separate clamping hooks (short or long, depending on requirements), separate spacers, separately long or short mounting rods, etc., to make such hinges compatible with various door or window frame sizes.This means that such a clamping hinge becomes complex, expensive, and not very user-friendly. For different stick overlaps that affect the depth of the mounting angle or that must be considered for determining the mounting angle size, the use of different adapters with different lengths is necessary. An example of such a complex construction is disclosed in DE 10 2009 040 465 A1. This prior art is also limited to a hinge for rotating frames. Based on these disadvantages of the prior art, the present invention therefore addresses the technical problem of providing a clamping hinge or a set of clamping hinges for numerous applications. Nevertheless, this should be achieved with the fewest possible parts. The clamping hinge should be simple, intuitive to use, lightweight, and inexpensive to manufacture. Furthermore, it should be easily mountable from the outside of the object being clamped. These aspects of the invention are addressed by the features of the main claim. Advantageous embodiments of the invention are set forth in the dependent claims. For this purpose, a clamping hinge is provided comprising a clamping element and a base body as well as a clamping hinge part, wherein the base body and the clamping hinge part are designed for connection with each other, the base body has an opening for receiving and fastening the clamping element in the base body, the opening of the base body has a tubular area for receiving a fixing screw and an adjusting nut, the clamping element is bent and has a clamping surface for resting against a target object and an insertion surface for inserting the clamping element into the opening of the base body, and wherein the insertion surface of the clamping element and the clamping hinge part are designed for connection with each other. The clamping hinge according to the invention is therefore suitable for a wide range of applications. For example, it serves to clamp a revolving door with an insect, pollen or particle protection screen or a sun protection fabric to the frame of a door or the like. It is also suitable for fixing in the front area of ​​such windows, doors or other openings in surrounding walls, e.g. for the purpose of mounting on a roller blind. This is achieved by designing the hinge according to the invention to be adaptive, so that several possible applications can be covered with few parts. In particular, it can be used for different pole flips, so that - as is necessary in the state of the art - different adapters of different lengths are no longer needed to overcome different pole flips. The invention makes it possible to create ever new recording options for a wide variety of applications. A significant advantage of the invention is that the parts of the hinge - insofar as they need to be screwed together - can be screwed together from the outside or from the side and are therefore easily accessible. The device according to the invention can thus be used as a door hinge that can be attached to a door frame, for example, of a revolving door with an insect screen, and that connects this door frame to the door jamb, i.e., the door's outer frame. For this purpose, the invention can be attached, for example, to the left-hand vertical profile of such a revolving door (as viewed from the front), e.g., an aluminum profile. Likewise, the attachment can also be made to the opposite side of such a vertical profile of a door with an insect screen. In another embodiment, the invention can be used as a roller blind mounting plate. Here, a roller blind, e.g., a roller blind without a guide rail, is fixed to a window frame. Furthermore, the invention can be incorporated in an embodiment of fixing the handle rail to the end of a fabric web, which can be used as an insect, pollen and / or particle protection screen or as a sun protection fabric or as a pleated blind or in another function. Another embodiment of the invention relates to the arrangement of the clamping device on a roller blind mounting plate, which is part of a roller blind that is arranged on a window frame. The clamping device according to the invention initially comprises a clamping element and a base body as well as a clamping hinge part. While the base body and the clamping element, which will be described in more detail below, act as the basis for the clamping device according to the invention, the clamping hinge part can be different modules that are connected to the base group of the base body and the clamping element. A clamping hinge component can be, for example, a door hinge for use with a door. It can also be a roller blind mounting plate, in which case the entire clamping device serves to clamp, and thus attach, a roller blind to a window frame. Furthermore, the clamping hinge component can also be a bracket with a screw fastening, as shown in principle in the figure. A clamping hinge component can therefore be designed in various ways and serve multiple applications. The basic structure of the construction according to the invention is described below, first in the form of a clamping device for use as a door hinge. It comprises a base body that can be designed as a short or long module. This is preferably a roughly cuboid-shaped component made of metal. The material properties are, in principle, irrelevant to the invention. Any suitable material can be used, e.g., sheet metal, aluminum, plastic, or the like. The base body is provided with an elongated opening that serves to receive and secure the clamping element within the base body. For this purpose, the opening extends through the entire length of the base body, resulting in corresponding openings on the respective upper and lower end faces of the base body. The opening itself contains a tubular section that also extends through the base body and serves to accommodate a fixing screw. The clamping element, the design of which will be described later, is inserted into the base body from one end face. The other end face of the base body is connected to the actual clamping hinge part 1, as will be explained in more detail later. A short fixing screw connects the clamping element, the short base body, and the clamping hinge part. These parts are connected with a long fixing screw when a long base body is used. Due to the design of the clamping element, which will be explained in more detail below, it is designed to be movable in the base body, so that the distance d between the clamping element and the clamping hinge is adaptively adjustable, meaning that the clamping range can be shortened or lengthened depending on the application. Due to the basic design described above, the invention allows for simplified screwing of these parts from their outside. This means simplified application for the user. The clamping element is initially designed in a plate-like shape. Over a distance of one-third to approximately half its length, the clamping element is bent by material forming, resulting in two different application areas. One application area is thus formed as a clamping surface which, together with its opposite counterpart of the clamping hinge part 1, overlaps the corresponding target object, e.g. the front face of a frame, a door or a window. Furthermore, in its bent state, the clamping object consists of an insertion surface for inserting the clamping element into the opening of the base body. If the distance d of the clamping area is to be set to its smallest value, which corresponds approximately to the height of the base body, the insert is inserted until the clamping element stops against the end face of the base body. The stop is formed by the area defined by the bend of the clamping element. If, however, the distance d of the clamping area is to be greater than the height of the base body or the base body, the insertion surface is only inserted into the opening of the base body to a corresponding depth. The creation of a clamping area with the aforementioned parts and the variability in the distance of the clamping area are made possible by the following measures. The creation of a clamping area is made possible by the fact that the insertion surface of the clamping element and the clamping hinge part are designed to be connected to each other. The connection is made using a short or long fixing screw, depending on whether a short or long base body is used. The fixing screw is inserted from the outside through a hole in the base of the clamping hinge part and screwed into the insertion surface of the clamping element. The screw connection on the insertion surface is created, for example, by means of an adjusting nut that is positioned transversely to the base of the clamping element's insertion surface in a designated double-grooved recess in the insertion surface. The adjusting nut, which has an internal thread, thus establishes the connection between the clamping hinge part and the clamping element via the fixing screw. The adjusting nut, like the insertion surface, is inserted into the opening of the base body. For this purpose, the opening of the base body preferably has the previously mentioned tubular section, dimensioned to accommodate both the fixing screw and the adjusting nut. The adjusting nut can be rectangular or square; the tubular section can be correspondingly cuboid in shape. For assembly purposes, it is advisable to first secure the insertion surface in the opening of the base body. To this end, the adjusting nut is advantageously inserted into the double-grooved recess in the insertion surface, and both parts are then inserted together into the opening of the base body using the tubular section. The clamping hinge part 1 can then be secured using the fixing screw by placing it against the opposite end face of the base body and subsequently tightening the screw. For the purpose of increasing or decreasing the distance d of the clamping area, the insertion surface of the clamping element preferably has a slot-shaped opening for length adaptation. This slot-shaped opening for length adjustment is connected to the aforementioned double-groove recess, which accommodates the adjusting nut and is located to the left and right of the slot-shaped opening. The double-groove recess is positioned in the area of ​​the slot-shaped opening adjacent to the clamping hinge component. These design features allow the clamping element to be moved into the opening of the base body to the desired extent when the locking screw is tightened. When the locking screw is fully tightened, the double-grooved opening, and thus the entire insertion surface, moves towards the clamping hinge part. The slotted opening provides a receiving space for the locking screw. The locking screw is therefore secured not only in the tubular section of the base body but also in the slotted opening of the clamping element's insertion surface. Since these structural parts are preferably located in the middle of the width of the clamping element and the base body, this results in an overall centered fixation of the parts of the clamping device to each other, which is of great advantage for a clamping effect with a central pressure distribution on the target object, e.g. the frame of a window or door, after the clamping device has been installed. If the distance d of the clamping area needs to be increased, the locking screw is turned accordingly. The adjusting nut, and thus the insertion surface connected to the adjusting nut via the double-grooved recess, is then turned out along the thread of the locking screw to the desired extent. The slot-shaped opening preferably extends from its area adjacent to the clamping hinge part to the area of ​​the bend where the insertion surface transitions to the clamping surface. This allows for maximum length adaptation over almost the entire height of the insertion surface within the base body. To improve the clamping effect and prevent the clamping device from slipping out of the clamp, for example due to vibrations or frequent use, it is advantageous to design the insertion surface and the clamping surface of the clamping element at an acute angle to each other. It is sufficient if the acute angle is a few degrees less than a right angle. The opening in the base body is designed as an elongated, narrow structure, at least as wide as the insertion surface. Advantageously, the length of the opening is such that, in addition to the insertion surface, there is also space for at least one bore for receiving a fastening screw. This at least one bore, preferably two bores at the two end faces of the opening, serve to create a stable connection between the base body and the corresponding surface of the clamping hinge part resting on its end face. For this purpose, the surface of the clamping hinge part has at least one fastening bore aligned with the bore in the base body. Preferably, two aligned bores are provided, both of which are arranged in line with the bores in the base body. The bore serves to receive a fastening screw. These additional screw connections ensure particularly good stability of the clamping device. The previously mentioned bore for receiving the fixing screw is preferably located in a line between the bores and in the middle between them. Due to the above, the entire clamping device is length-adaptive and therefore ideally suited for numerous applications. In an advantageous embodiment, the clamping hinge device has an adhesive strip for pre-fixing the device to the target object, e.g. the frame of a door or window. In the application of this invention, where the clamping hinge component is configured as a door hinge, the clamping element, due to the distance d of the clamping area, overlaps a door frame or jamb. The open part of the clamping device is placed onto the end face of the frame. The clamping surface of the clamping element comes into contact with the material of the door frame at the clamping point. The system is then securely fastened to the frame from the outside using the fixing screw. This results in the entire device being fixed to the door frame by means of the door hinge. The clamping device described above can also have a roller blind mounting plate instead of a door hinge, as explained at the beginning. In this embodiment, the roller blind mounting plate is fixed to the end face of the base body in the same way and adjusted to the desired distance d of the clamping area using the fixing screw, thus enabling contact between the clamping surface and the target object, e.g., a window frame. A handle rail is also arranged in the area of ​​the roller blind mounting plate, which is positioned on the lower edge of a fabric panel of an insect, pollen, or particle screen, a sunshade fabric, or a pleated blind. In another embodiment of the invention, it extends to a combination of the base body and the clamping element with a roller blind mounting plate, which is fixed at one end to the end face of the base body as described above, and which fixes a roller blind housing at its other end with a screw. The roller blind housing is thus clamped to a door frame, which is gripped by the clamping surface and the base body as described above. As already explained in the other embodiments, the clamping takes place at a clamping point. The distance d of the clamping area is also fixed here by means of the clamping screw. Exemplary embodiments, to which the invention is of course not limited, are explained with reference to the following figures, which show: Fig. 1: Schematic representation of a clamping device according to the invention for a door hinge on a revolving door; Fig. 2: Schematic representation of a clamping device according to the invention for fixing a roller blind to a window frame or for fixing a handle rail of a fabric panel; Fig. 3: Schematic representation of the application of the invention in connection with a roller blind mounting plate; Fig. 4: Sectional view of the clamping device as a door hinge arranged on a frame; Fig. 5: Schematic representation of a clamping device mounted on a frame; Fig. 6: Detailed view of the individual components of the clamping device; Fig. 7: Schematic representation of the construction of the clamping device in a side view using the example of a door hinge; Fig.Fig. 8: Schematic representation of the construction of a clamping device in conjunction with a roller blind mounting plate in a roller blind housing; Fig. 9: Schematic representation of the clamping device with a roller blind mounting plate arranged in a handle rail; Fig. 10: Schematic representation of the invention with a holder and a screw fastening; Fig. 11: Schematic representation of an assembled device according to Fig. 10. Fig. 1 shows the device according to the invention as a door hinge 14, which is attached to a door frame 13, for example a pivot door having an insect screen, and connects this door frame 13 with the door jamb, i.e. the frame 15 of a door. The application of this invention in the embodiment of the clamping hinge part 1 as a door hinge 14 is further shown in a sectional view in Fig. 4 and in the application case in Fig. 5. In another embodiment, the invention can be used as a roller blind mounting plate 17. Here, a roller blind, e.g., a roller blind without a guide rail, is fixed to a window frame 12. Furthermore, in another embodiment, the invention can be used to fix the handle rail to the end of a fabric strip, which can be used as an insect, pollen, and / or particle protection screen, as a sunshade, as a pleated blind, or in another function. Such examples are shown in Fig. 2. Another embodiment of the invention relates to the arrangement of the clamping device on a roller blind mounting plate 18, which is part of a roller blind 19 that is arranged on a frame 12 of a window, as can be seen approximately in Fig. 3. In all these embodiments, the clamping device according to the invention has a clamping element 3 and a base body 2 as well as a clamping hinge part 1. While the base body 2, 8 and the clamping element 3 act as the basis for the clamping device according to the invention, the clamping hinge part 1 can be different modules that are connected to the base group of the base body 2, 8 and the clamping element 3. In the embodiment shown in Fig. 1, a clamping hinge part 1 is a door hinge for use in connection with a door. In another embodiment, the roller blind mounting plate 17 is used, so that the entire clamping device serves to clamp, i.e., to fasten a roller blind 16 to a window frame 12, as is mentioned as an example in Fig. 2. Furthermore, the clamping hinge part 1 can also be a holder 18 with a screw fastening, as shown in principle in Fig. 3. A clamping hinge part 1 can therefore be designed in different ways and serve several possible uses. The basic structure of the construction according to the invention is shown in Fig. 7 and Fig. 6. The invention shows here the design of a clamping device for use as a door hinge, which is described in more detail below. A basic structure is visible, shown as the short module 2, but which can also be designed as the longer module 8. It is an approximately cuboid-shaped component. The base body is provided with an elongated opening 22, which serves to receive and secure the clamping element 3 in the base body 2, 8. For this purpose, the opening 22 and a vertically continuous tubular section 23 within it are provided throughout the base body, resulting in corresponding openings at the respective upper and lower end faces of the base body 2, 8. The tubular section is described further below. The clamping element 3 is inserted into the base body 22 from one end face of the base body 2, 8, as shown in Fig. 7. The other end face of the base body 2, 8 is connected to the actual clamping hinge part 1. A fixing screw 6 connects the clamping element 3, the short base body 2, and the clamping hinge part 1. These parts are connected with a long fixing screw 10 when a long base body 8 is used. The clamping element 3 is arranged to be slidable in the opening 22, so that the distance d between the clamping element 3 and the clamping hinge 1 is adaptively adjustable, meaning that the clamping range can be shortened or lengthened depending on the application. The clamping element 3 is initially designed in a plate-like shape. Over a range of one-third to approximately half its length, the clamping element is bent by material forming, resulting in two different application areas. One application area is thereby formed as a clamping surface 24, which, together with its opposite counterpart of the clamping hinge part 1, overlaps the corresponding target object, e.g. the front face of a frame, a door or a window. Furthermore, in its bent state, the clamping object 3 consists of an insertion surface 25 for inserting the clamping element 3 into the opening 22 of the base body 2, 8, as shown in the assembled state in Fig. 7 and in the pre-assembled state in Fig. 6. If the distance d of the clamping area is to be set to its smallest value, which corresponds approximately to the height of the base body 2 or the base body 8, the insert 25 is inserted until the clamping element 3 stops against the end face of the base body 2, 8. The stop is formed by the area defined by the bend of the clamping element 3. If, however, the distance d of the clamping area is to be greater than the height of the base body 2 or the base body 8, the insertion surface 25 is only inserted to a corresponding depth into the opening 22 of the base body 2, 8. The creation of a clamping area with the aforementioned parts and the variability in the distance of the clamping area are made possible by the following measures. The creation of a clamping area is made possible by the fact that the insertion surface 25 of the clamping element 3 and the clamping hinge part 1 are designed to be connected to each other. The connection is made by means of a short fixing screw 6 or a long fixing screw 10, depending on whether a short base body 2 or a long base body 8 is used. The fixing screw 6 or 10 is guided from the outside through a bore 27 in the base of the clamping hinge part 1 and screwed into the insertion surface 25 of the clamping element 3, Fig. 6. The screw connection on the insertion surface 25 is created by means of an adjusting nut 7, which is positioned transversely to the base of the insertion surface 25 of the clamping element 3 in a corresponding double-grooved recess 29 in the insertion surface 25. The connection between the clamping hinge part 1 and the clamping element 3 is thus created by means of the adjusting nut 7, which has an internal thread, by means of the fixing screw 6, 10, Fig. 6, Fig. 4. The adjusting nut 7, like the insertion surface 25, is inserted into the opening 22 of the base body 2, 8. For this purpose, the opening 22 of the base body 2, 8 has a tubular section 23, dimensioned to accommodate the fixing screw 6, 10 and the adjusting nut 7. The adjusting nut 7 can be rectangular or square; the tubular section 23 can be shaped accordingly, as shown in Fig. 6. For assembly purposes, it is advantageous to first secure the insertion surface 25 in the opening 22 of the base body 2, 8. For this purpose, the adjusting nut 7 is advantageously inserted into the double-grooved recess 29 in the insertion surface 25, and both parts are then inserted together into the opening 22 of the base body 2, 8 using the tubular section 23. The clamping hinge part 1 can then be secured using the fixing screw 6, 10 by resting it against the opposite end face of the base body 2, 8 and subsequently tightening the screw. For the purpose of increasing or decreasing the distance d of the clamping area, the insertion surface 25 of the clamping element 3 has a slot-shaped opening 28 for length adaptation, as shown in Fig. 6. This slot-shaped opening 28 for length adaptation is shown in conjunction with the arrangement of the aforementioned double-groove recess 29, which serves to receive the adjusting nut 7 and is formed as an adjacent groove-shaped recess to the left and right of the slot-shaped opening 28. The double-groove recess 29 is located in the area 30 of the slot-shaped opening 28 adjacent to the clamping hinge part 1. These design features allow the clamping element 3 to be moved into the opening 22 of the base body 2, 8 to the desired extent when the locking screw 6, 10 is tightened accordingly. When the locking screw 6, 10 is fully tightened, the double-grooved opening 29, and thus the entire insertion surface 25, moves towards the clamping hinge part 1. The slotted opening 28 provides a receiving space for the locking screw 6, 10. The locking screw 6, 10 is therefore fixed not only in the tubular section 23 of the base body 2, 8 but also in the slotted opening 28 of the insertion surface 25 of the clamping part 3, Fig. 6, Fig. 4. Since these structural parts are located in the middle of the width of the clamping element 3 and the base body 2, 8, this results in an overall centered fixing of the parts of the clamping device to each other, which is of great advantage for a clamping effect with central pressure distribution on the target object, e.g. the frame of a window or a door, after the clamping device has been mounted. If the distance d of the clamping area is to be increased, the fixing screw 6, 10 is turned accordingly. The adjusting nut 7, and thus the insertion surface 25 connected to the adjusting nut 7 via the double-grooved recess 29, are then turned out along the thread of the fixing screw 6, 10 to the desired extent. The slot-shaped opening 28 preferably extends from its region 30 adjacent to the clamping hinge part 1 to the inner region of the bend 31, where the transition of the insertion surface 25 to the clamping surface 24 takes place. This enables maximum length adaptation over almost the entire height of the insertion surface 25 within the base body 2, 8. To improve the clamping effect and to prevent the clamping device from slipping out of the clamp, for example in the case of vibrations or frequent use of the clamping device, the insertion surface 25 and the clamping surface 24 of the clamping element 3 are bent at a slight acute angle to each other. The opening 22 in the base body 2, 8 is designed as an elongated, narrow structure, having a width at least equal to that of the insertion surface 25. The length of the opening 22 is designed such that, in addition to the insertion surface 25, there is also room for two bores 32 for receiving a fastening screw 4. These bores serve to provide a stable connection between the base body 2, 8 and the corresponding surface of the clamping hinge part 1 resting on its end face. For this purpose, the surface of the clamping hinge part 1 has two bores 26 aligned with the bore 32 in the base body 2. These additional screw connections ensure particularly good stability of the clamping device. The previously mentioned bore 27 for receiving the fixing screw 6, 10 is then located on a line between the bores 26 and in the middle between these bores. Due to the above, the entire clamping device is length-adaptive and therefore ideally suited for numerous applications. Additionally, the clamping hinge device 1 can have an adhesive strip 9 for pre-fixing the device to the target object, e.g. the frame of a door or window. The invention described above, due to the distance d of the clamping area, overlaps a door frame or jamb. The open part of the clamping device is placed onto the end face of the door frame. The clamping surface 24 of the clamping element 3 comes into contact with the material of the door frame at the clamping point 5. The system is securely fastened to the door frame from the outside using the fixing screw 6. This results in the entire device being fixed to the door frame 13 by means of the door hinge 14. The clamping device described above, in the form of a roller blind mounting plate, is illustrated in Figures 8 and 9. In this embodiment, the roller blind mounting plate is fixed to the end face of the base body 2, 8 in the same manner and adjusted to the desired distance d of the clamping area via the fixing screw 6, thus enabling contact between the clamping surface 24 and the target object, e.g., a window frame 12, via the clamping point 5. A handle rail 20 is also arranged in the area of ​​the roller blind mounting plate 22, which is positioned on the lower side of a fabric panel of an insect, pollen, or particle screen, or of a sunshade fabric, or of a pleated blind (not shown) (Figure 9). In the embodiment shown in Fig. 4, the combination of the base plate 2 and the clamping element 3 with a roller blind mounting plate 7 serves to fix a roller blind 16 to a door frame 12. The embodiments in Figs. 10 and 11 show the inventive configuration of a combination of the base body 2 and the clamping element 3 with a roller blind mounting plate 18, which is fixed at one end to the end face of the base body 2 as described, and which fixes a roller blind housing 19 at its other end with a screw. The roller blind housing 19 is thus clamped to a door frame 12, which is engaged by the clamping surface 24 and the base body 2 as described above. As already explained in the other embodiments, the clamping takes place at a clamping point 5. The distance d of the clamping area is also fixed here by the clamping screw 6.
