Description

Field of the invention

The invention relates to a clamping device for fixing an insect screen door, in particular an aluminum frame insect screen door, on the frame of a door. Furthermore, the invention relates to a system with a corresponding clamping device and an insect screen door, in particular an aluminum frame insect screen door. In this case, the clamping device according to the invention is characterized in that a fastening is possible even with a very limited space available. Other uses for the clamping device according to the invention are conceivable. The clamping device according to the invention is quite generally suitable for attachment of stem elements before building openings, but can also be used for entirely different fastening purposes.

State of the art

Various clamping devices for fastening, for example, curtain rods, sun visors and insect screens are already known from the prior art. Basically, the attachment of said objects by means of a clamping device has the advantage that these drills in principle, d. H. damage-free, can be done.

Curtain rods, sun visors, etc. are usually attached to a window or door. With insect screens, however, it is such that they are attached to the frame of a door or a window to ensure the opening function of both the original window or the original door on the one hand and also an insect screen or insect screen on the other. It should be considered for the construction of clamps for insect doors or windows that they - compared with, for example, curtain rods and sun visors - have a greater weight and thus the attachment is more difficult. In particular with insect screen doors acts on the clamping device unfavorable torque, since the door elements can be hinged only on one side of the window frame to obtain the opening function, and thus on the opposite side of the frame no abutment for receiving the torque is present. In addition, when mounting insect screen doors or windows in building openings, it must be taken into consideration that the available space around a window frame is often limited. This starting situation is in the 1 and 2 illustrates:

1 illustrated in a schematic representation of the available space available between the frame 2 and a door leaf 4 , wherein the individual representations a) to c) show different frame sections. It is always a frame 2 in a masonry 3 edged. In 1a) is also a door leaf 4 represented, the area offset to the frame 2 is arranged. There is no overlap of the door leaf 4 with the frame inside edge 5 , In contrast, in 1b) a door leaf 4 shown, the half-surface offset to the frame 2 is arranged. There is thus a certain overlap area b in front of the frame inside edge 5 of the frame 2 , The distance between the door 4 and the frame 2 in this overlap range is d and is therefore limited. The situation is similar with that in 1c) illustrated situation, which is a flush arrangement of door leaves 4 to frame 2 represents. Again, there is an overlap area b between the door leaf 4 and the frame 2 , this now along the entire frame inside edge 5 extends. In the example shown, the overlapping area b is thus identical to the width of the frame inner edge c. The gap formed thereby again only has a width d.

2 shows an example of the installation situation of a clamping device according to the invention using the example of a flush frame section. How out 2 it can be seen limited in the case of the half-surface offset and flush frame section, the gap width d that for the attachment of a clamping device 1 available space. Typically, this gap width d is only about 10 mm. In this gap now has the frame 2 from three sides embracing a clamping device 1 be attached, the inside edge of the frame edge may have a thickness D, which may have a maximum of the gap width d. This special installation situation with half-surface offset or flush frame sections is not taken into account in the clamping devices known from the prior art.

From the prior art, a solution is known that refrains to attach the insect screen on the frame of a door. Instead, the insect screen door is clamped by means of punches directly into a wall opening. As a result, the frame used therein unfavorably has very large dimensions and is relatively expensive. In addition, it can not be ensured via a pinching of the frame in a wall opening that this solution is universally applicable, because of a possibly existing bevel within the wall opening, which is often provided for better drainage of rainwater.

The EP 1 457 638 A1 discloses an insect screen with a frame. On the frame, a grid or fabric is attached, and by means of a fastening device, an insect screen is to be releasably and non-destructively attached to a window or door frame. In this case, the fastening device has at least one part of the window or door frame engaging behind retaining claw, wherein the frame has a form-fitting region preferably formed by a groove for attachment of the retaining claw on the frame, wherein the retaining claw adjustable transversely to a lattice or tissue-containing level of the insect screen connected to the frame. In order to enable in the simplest possible way a secure, screw and non-destructive installation on a door or window floor, it is provided that the retaining claw and the frame are connected directly by a tongue-and-groove connection designed as a positive connection, wherein the frame and the retaining claw reciprocally shaped form-fitting regions. The elicitation of a clamping action of the window or door latch engaging behind retaining claw is effected by an actuation in the direction of the clamping effect to be achieved. However, the document in no way addresses the specific problem of the limited space available between the frame and casement, in particular, the problem is not addressed at halbflächenversetzten and flush frame sections. In addition, the disclosed device is relatively space-consuming, and it can be doubted whether this meets the requirements placed on a limited amount of space between frame and sash. In addition, it must be doubted whether this clamping device, the torques, the one-sided attachment z. B. an insect screen Alurahmentür occur, can accommodate.

The WO 89/08180 A1 discloses a clamp mount for sun protection devices, which is attachable to a frame or window frame of a window or the clothing of a window opening. The disclosed clamp holder consists of a first and a second clamping bracket, each forming a clamping flange and are held together with guide members. A threaded spindle serves to contract the clamping flanges. To connect the spindle with the two support parts serve spindle mounts, of which provided on the first support member spindles a threaded bore and the spindles on the other support part contains a longitudinal bearing. A cap serves not only aesthetic purposes, but also to the cohesion of the elements under the support of the spindle. The cited document is therefore a clamp for sun protection devices, but not for insect screen doors. To mount these doors greater stability of the clamp is required, and there are additional demands on a clamping device to ensure that the opening function of the insect screen door on the one hand and the original door on the other hand can be ensured. Nevertheless, the document discloses a way to attach a clamping device basically to a window frame of a door, again the direction in which the clamping effect is achieved, with the operating direction of the spindle mechanism coincides. The two clamping cheeks are in clamping state substantially parallel to each other.

The WO 02/099236 A1 discloses a support member with a clamping technique consisting of two parts. This is used to hold pipes, rods or ropes, which are tensioned. It is an L-angle with a pin on an angle and an S-angle with grid holes and recess for receiving pipes, rods or ropes provided. It should be achieved, that holds the support member on the window sash or other frame only by the grid system of the two support parts during assembly of tensioned pipes, rods or ropes. The document shows only a single embodiment in which the carrier element is shown on the window frame. The exact mechanism of how a sufficiently large clamping action for attachment of the support element to the window sash is to be achieved is not further described in the document.

Possibly, by the mentioned grid system, a distance adjustment between the L-angle and the S-angle. The disclosed support member is used only for the installation of tensioned pipes, rods or ropes, which are far less massive than an insect screen and thus far easier to fasten. Also in this citation, the problem that arises with attachments on the frame of a door or a window, taking into account the limited space available in halbflächenversetzten and flush frame sections, not addressed.

Description of the invention

It is the object of the present invention to provide a clamping device for fixing an insect screen door to the frame of a door, which overcomes the disadvantages of the known devices of the prior art. In particular, it is the object of the present invention to provide a clamping device for attaching an insect screen door to the frame of a door that can be attached to the frame of a door, without causing damage there, the function of the original existing door and the insect screen door and which is also universally applicable. In particular, the clamping device should also be suitable for those applications in which due to half-surface offset and flush frame sections only a limited amount of space between the frame and sash is available. Furthermore, an object is to provide a clamping device that can span existing on a window frame sealing elements.

The object of the invention is achieved by the independent claims 1 and 27 of the invention.

According to a first aspect of the invention, this relates to a clamping device for fixing an insect screen door on the frame of a door. The term door should now and in the following include the term window. The insect screen door may in particular be an aluminum frame insect screen door. Needless to say, the presented clamping device is not only suitable for fixing an insect screen door, but it also allows in case of doubt, to fix pollen filter doors or sun protection doors on the frame of a door. Also, the clamping device according to the invention can be used for completely different fastening purposes.

According to the invention, the clamping device has a first holding element and a second holding element, which can be connected or connected to one another and which can engage around the frame of a door together from three sides. In this case, the first support member as well as the second support member itself may be formed one or more pieces. According to a preferred embodiment of the invention, the first and / or the second support member are formed as angular support members. Such an angle can be for example about 90 °; but other angulations are also conceivable, for example, an obtuse angle. In particular, the first and / or second support element may be L-angle-shaped support elements. In this case, different regions of the first and the second holding element are preferably substantially flat. The first and the second support member may be provided completely separable from each other. It is also possible that the first support member and the second support member are not completely separate from each other, but always have a direct or indirect connectedness with each other, which can be realized for example by other components of the clamping device. The first and second support members are connectable to each other so that the first and second support members are in direct or indirect contact with each other in the assembled state. Preferably, the first and the second support member made of metal, made wholly or partly of metal, in order to achieve sufficient mechanical strength, stability or even a sufficient flexibility.

The first support member and the second support member may surround the frame of a door together from three sides. It concerns a situation, as already schematically in 2 has been described in the introductory part of the present application: The in 2 shown frame 2 has a frame inside edge 5 and a frame outside 6 and a frame inside 7 on. These pages define the three sides of a frame made by a clamp 1 can be encompassed. It is possible, for example, that the first support member surrounds the frame of two sides, for example, the frame outside and the frame inner edge, whereas the second support member surrounds the frame of the frame inside and the frame inside edge. It is possible that the position of the first support member and the second support member in the state of gripping the frame have an overlap with each other, for example, in front of the frame inner edge of the window frame. But other embodiments of the first and second support member for encompassing the frame of a door from three sides are conceivable.

According to the invention, furthermore, a connecting element for connecting the two holding elements and an actuating element for initiating a clamping force. According to a preferred embodiment of the invention, the actuating element is actuated substantially along a direction orthogonal to the clamping force to be effected. According to an alternative embodiment of the invention, the actuating element is actuated substantially parallel to the clamping force to be effected. The connecting element ensures that the two support elements can be brought into contact with each other, it may be a direct or indirect contact. Preferably, the relative position of the two support members is also substantially fixed to one another, that is, at least parts of the two support members can not change their position with respect to at least parts of the other support member. The connecting element itself can be formed in one or more parts. For example, it may be a system comprising at least one screw and one nut. Also, the actuator can be formed one or more parts and, for example, also include a system of screw and nut. According to a preferred embodiment of the invention, the connecting element and the actuating element are identical. The actuator initiates a clamping force, that is, by the actuation of the actuating element, the clamping force to be effected is caused. The direction of actuation is defined according to the nature of the actuator. If, for example, the aforementioned system of screw and nut is concerned, then the actuating direction is identical to the screwing direction or the axis of the screw. The actuation can take place substantially along a direction orthogonal to the clamping force to be effected, which means that the actuation takes place in a direction orthogonal to the frame inner edge of a window frame.

According to the invention, the clamping device further comprises a Richtungsumlenkelement coupled or coupled to one of the two support members, in particular orientation fixed coupled or coupled, and which is further coupled to the actuating element so that mediated upon actuation of the actuating element on the Richtungsumlenkelement a change in orientation of the first and second support member relative to each other is effected or effected, so that a sufficiently large clamping force between the first and the second support member for attaching an insect screen door, in particular an aluminum frame insect screen door, on the frame of a door is achieved or achieved becomes. In this case, the actuating element can be coupled directly or indirectly to the Richtungsumlenkelement, it is for example a direct or indirect contact between the actuating element and the Richtungsumlenkelement conceivable. While the above-mentioned connecting element for connecting the two support elements causes only a pre-fixing of the two support members to each other, is caused by the actuation of the actuating element on the Richtungsumlenkelement a change in orientation of the first and second support member relative to each other or is effected. Such a change in orientation may be a change in the relative position of the two support elements relative to one another in space. According to a preferred embodiment of the invention, the two support members are tilted relative to each other. The orientation change of first and second support member relative to each other can also be caused by a change in shape of at least one of the two support members. For example, at least one of the two support elements can be bent by the action on the direction deflecting element. The orientation change may also include a change in distance between the first and second support member relative to each other, but preferably the distance between the first and second support member relative to each other substantially unchanged, as he has already been preset by the above-mentioned connecting element for connecting the two support members. For example, if the two support elements are angularly substantially flat support elements, then each of the support elements can have a front surface and a side surface, the front surfaces being able to engage around the frame on the inner edge of the window frame and the side surfaces on the outer frame or window frame side respectively , It is for example possible that the two front surfaces of the support members are connected to each other by the connecting element and in particular have an overlap with each other. This overlap or contact of the two front surfaces with each other remains fixed even during the actuation of the actuating element substantially. On the other hand, by the actuation of the actuating element, a change in orientation of the two side surfaces of the support elements to each other, it is for example possible that the two side surfaces are tilted against each other. Alternatively, it is possible that the relative angle between the front surface and the side surface of one of the two support members by the direction deflecting a change, for. B. experiences to a more acute angle. Also in this way, the side surfaces of the two support members are now oriented differently to each other after the action on the Richtungsumlenkelement. For example, the two side surfaces may initially have been parallel to one another, and are then tilted against each other. The orientation change of first and second support member relative to each other thus takes place at least with respect to a part of the respective support members. Basically, it should be noted that the orientation change of the two support members to each other by the actuation of the actuating element in an actual mounting on a window frame of a door is not necessarily visible from the outside: namely, there are areas of the support elements commonly in contact with the frame outside or window frame inside, which are often oriented parallel to each other. Due to the change in orientation occurs rather in this system a correspondingly strong clamping force that just is not the same size over the entire contact surface, as would be the case without such a change in orientation of previously parallel support members. The orientation change thus essentially describes the mechanism of action of the clamping principle used.

According to a preferred embodiment of the invention, the Richtungsumlenkelement on a pivot bearing. This pivot bearing can be designed differently. It has an attachment point or attachment region around which a rotation of a component can take place. For example, the rotary bearing may have a circular segment-shaped cross section. According to an alternative embodiment of the invention, the rotary bearing has a substantially linear cross-section or such a cross-sectional edge. Other shapes, z. As a slightly or strongly curved, elliptical or oval cross-sectional configuration are possible. According to a preferred embodiment of the invention, it is a rounded design of the pivot bearing with a rounded cross-section. Within this application, the term fillet is used for both concave and convex shapes. Other embodiments may consist in a grid, the z. B. in staircase or can also be applied linearly. Also, arched formations may be provided with a screening. According to a preferred embodiment of the invention, one of the two holding elements is in direct contact with the Richtungsumlenkelement or the pivot bearing. Preferably, this orientation is fixed. According to a preferred embodiment of the invention, it is such that actuated by an actuation of the actuating element of the two support elements in abutment with the pivot bearing and is rotated in this manner via the pivot bearing, whereby a change in orientation of the first and second support member is effected relative to each other , According to a preferred embodiment of the invention, this is done by tightening a screw-nut system.

According to an alternative embodiment of the invention, the directional deflection element may be a gear mechanism. For example, a gear or a receptacle could be mounted on a displaceable axis. According to a preferred embodiment of the invention, the direction deflecting element, in particular if it has a pivot bearing plastic. According to a preferred embodiment of the invention, the Richtungsumlenkelement TPE or rubber, which allows a particularly good slip resistance in the range of contact points or surfaces of Richtungsumlenkelementes.

According to a preferred embodiment of the invention, the first and / or the second support member are formed as an angle-shaped support members, in particular as L-angle-shaped support members. The two areas of the or the support elements may have a regular or irregular shape, they can, for. B. indentations and / or openings. Preferably, the angular support members are formed substantially flat, wherein the term refers flat to the respective angle forming region. According to a preferred embodiment of the invention, an angular support member has a substantially flat side surface and a substantially flat front surface. In this case, in particular, in the mounted state of the frame inner edge of the door facing side of the support member is formed substantially flat. If the use of material to be minimized while maintaining the flexural rigidity or even only to increase the strength, the profiling or the introduction of beads in the support members may be beneficial.

According to a preferred embodiment of the invention, the first and the second support member in the assembled state on an overlap region with each other, wherein within this overlap region in the support members each have an opening for receiving the connecting and / or actuating element is provided. In the case of angular support elements, it is preferred that the overlapping area is formed by an overlapping of front surfaces of the two support elements, that is located in a region directly opposite the window frame edge of a window frame in the assembled state or conforms to this. According to a preferred embodiment of the invention, the two openings in the respective support member are dimensioned substantially equal and can then be brought into coincidence with each other. Through these two openings through the connection and / or actuator can be inserted through. Preferably, the two openings are openings for receiving a screw from a system of nut and screw as a combined actuating and connecting element. In the overlapping area between the first and second support members, the first and second support members may be in direct contact with each other. But it is also possible that there are other elements of the clamping device between them, so that although an overlap exists, but instead of a direct only an indirect contact between the first and second support member exists.

According to a preferred embodiment of the invention, the two support members of the clamping device according to the invention are substantially identical. In particular, they may be substantially identically dimensioned and / or mirror-inverted relative to one another.

According to a preferred embodiment of the invention, the clamping device has a Abstandgrößbeinstellmechanismus, which allows to adjust the distance between the first and the second support member to the width of the window frame of a door. For example, the first and the second support member can be moved relative to each other, so that a portion of the first support member with the window frame outside and a portion of the second support member may come into contact with the frame inner side of the window frame. Preferably, there is an overlap between partial areas of the two support elements with each other. The Abstandsgrobeinstellmechanismus not only allows the displacement of the first and second support member to adapt to the width of the frame of a door, but it also allows a separate fixing or fixing of said distance. It is therefore not sufficient to bring the first and the second support member by hand in contact with the frame inside and the outside frame of the window frame of a door and hold them there manually. Instead, a fixation of the distance is done by technical means.

According to a preferred embodiment of the invention, the first and the second support member in the assembled state on an overlap region with each other, wherein within this overlap region in the support members each have an opening for receiving the connecting and / or actuating element is provided. In combination, at least one of the mentioned openings in the form of a guide trough is formed with a plurality of detent positions, which allows a coarse adjustment of the distance between the first and the second support member. It is preferred that both openings are designed in the form of a guide cheek having a plurality of detent positions. The two support members can now be moved against each other, and when receiving the connection and / or actuating element, the distance between the first and the second support member is preset or fixed depending on the choice of the position of the connecting and / or actuating element in a certain detent position and can be flexibly adapted to a width of a window frame of a door.

If the actuating element and / or the connecting element designed as a system comprising at least one screw and nut, it can - as already stated - the actuation and / or connecting done by tightening the screw. According to a preferred embodiment of the invention, an anti-rotation is provided, which can prevent or prevent the co-rotation of the respective other system component of nut or screw when operating and / or connecting. According to a preferred embodiment of the invention, this rotation is ensured by a specific outer shape of the mother. This can for example be formed in its outer periphery substantially rectangular. If this rectangular-shaped nut is now guided in one of the two holding elements in a correspondingly dimensioned guide trough, turning the nut in this manner is reliably prevented when the screw is tightened. Other external shapes of the nut to prevent co-rotation are of course conceivable, also other known in principle anti-rotation.

According to a preferred embodiment of the invention, a captive is provided which can prevent or prevent complete separation of the screw and nut from each other. This facilitates the assembly of the clamping device according to the invention on the frame of a door. For example, it is possible that the nut and screw are in contact with each other by means of a bracket, which can prevent or prevent complete separation of screw and nut from each other. Other embodiments of a captive are of course possible.

According to a preferred embodiment of the invention, an inner surface of the first and / or the second support member is at least partially provided with slip-resistant pads, in particular foam rubber pads. Preferred materials are for example TPE, hard rubber or EPDM. The Shore A hardness of the anti-slip pads is for example 10 to 90, preferably 30 to 85, most preferably 50 to 80. Basically, that - the softer the material is - an unwanted twisting of the pads when inducing a clamping effect occurs more easily, which is why In principle, rather larger Shore A hardnesses are preferred. The slip resistant pads may be regular or irregular in shape, they may have a closed or perforated surface. The slip-resistant pad or slip-resistant pads can be glued, for example, to the respective support member, plugged by special design or even screwed. If the anti-slip pads are glued to the support members, then the use of a highly cohesive adhesive is preferred. When using such a highly cohesive and thus hard adhesive, the degree of crosslinking and / or the molecular weight of the adhesive are very high. Suitable examples are superglue of cyanoacrylate or epoxy adhesive. The slip-resistant overlay or slip-resistant overlays come in mounted condition preferably with the window frame outside or the frame inside the window frame in contact. The slip-resistant pads prevent accidental slipping of the clamping device, especially in cases where the frame is made relatively smooth. In addition, a twisting of the clamping connection is also effectively prevented by an effective torque of the weight of an insect screen door mounted by means of the clamping device. If a slip-resistant support is provided on each of the two support elements, then it is possible for these two slip-resistant supports to be dimensioned substantially identically. In the case of angle-shaped, in particular L-angle-shaped support elements, the slip-resistant supports are preferably located on the inner surfaces of the side surfaces of the two support elements.

According to a preferred embodiment of the invention, the clamping device has a receiving element for receiving an insect screen door. This receiving element may be one or more parts, compact or hollow, symmetrical or asymmetrical. It is also possible that not only a single receiving element, but a plurality of receiving elements per clamping device are provided. The inclusion of an insect screen door through the female element itself can be done in different ways, eg. B. by inserting, pushing in, a clip mechanism, gluing, pinning or screwing.

According to a preferred embodiment of the invention, the at least one receiving element comprises a hinge receptacle. By providing such a hinge receptacle, it is possible to fasten the insect screen door to be fastened in a particularly simple manner to the clamping device.

According to a further preferred embodiment of the invention, the receiving element is formed integrally with one of the two support elements. For example, the receiving element may be integrally formed or glued to one of the two support elements. The receiving element and the one of the two support members may be formed of the same or of different materials. According to a particularly preferred embodiment of the invention, the receiving element on plastic, and the one of the two support members, which is integrally formed with the receiving element is at least partially encapsulated with the plastic. This provides a more attractive appearance of the entire clamping device and for a better corrosion resistance of the clamping device, in addition, for a secure connection of the support member and receiving element.

According to a preferred embodiment of the invention, the receiving element is angled, in particular L-shaped angled and / or Z-angled, formed, and in an area which is oriented parallel to a front surface of one of the support members, is an opening for receiving the connection and / or actuator provided. In this case, the opening in the receiving element correlates with the opening or openings in the holding element or the holding elements, so that the connecting and / or actuating element can protrude through all openings. According to a particularly preferred embodiment of the invention, the receiving element is Z-angled and has at least three regions, wherein the first region of the Z-shaped angled receiving element in the assembled state substantially parallel to a front surface of one of the support members and wherein the second region substantially is oriented parallel to a side surface of the same support member, and further wherein the third region has a receiving area, in particular a hinge receptacle. In this case, the third region may also have more than one receiving area or a hinge receptacle. The described preferred embodiment of the invention enables a particularly simple one-piece embodiment of the receiving element with one of the two support elements. One of the two support elements is, so to speak, in preassembled contact with the receiving element, which further simplifies the assembly of the clamping device according to the invention. The front surface of one of the support elements and the side surface of the same support element preferably form a substantially L-shaped support element.

According to a preferred embodiment of the invention, the dimensions of the receiving element and the two support members are selected so that a distance between an outer insect screen door opening area and the inner edge of the frame of 15 mm to 25 mm, in particular about 20 mm, is ensured to ensure insect tightness. This is, for example, a distance between circumferential side surfaces of the insect screen door and the inner edge of the window frame. It comes in this way to a sufficient coverage of the insect screen door with the frame of the door. The receiving element, in particular a possibly existing hinge receptacle, so may not be exactly in a corner on the frame, but must be laterally offset beyond this provided by the distance described, since otherwise between the Insect screen door or its frame on the one hand and the frame of the door on the other hand gaps could arise that would allow insects to bypass the insect screen door. The lateral offset should preferably be present in a vertical as well as in a horizontal orientation; it can be the same size or different sizes in both directions.

According to a further preferred embodiment of the invention, the clamping device in the contact area to a window frame inner edge only a total thickness of 10 mm maximum. With such dimensions, it is possible, even with a significant limitation of the installation space, for example, in semi-offset and flush frame sections, to mount the clamping device according to the invention. The total thickness in the contact area to the frame edge edge is made up of all the elements of the clamping device located in front of the frame edge. For example, the thickness of an addition of front surfaces of mutually overlapping support members calculated, optionally comes in the case of a Z-shaped angled receiving element, which may be integrally formed with one of the two support members, nor the thickness of the receiving element in this area added. If necessary, further components of a clamping device which are likewise provided in the contact area to form a frame inner edge are likewise included in the determination of the total thickness of the clamping device.

Of course, the features of the clamping device described above may be combined in whole or in part with one another to form further embodiments of the invention.

According to another preferred embodiment of the invention, this relates to a system comprising at least one clamping device and an insect screen door, in particular an aluminum frame insect screen door. In this case, the clamping device may have one or more or all the properties that have been specified above in the description of the clamping device according to the invention itself. The insect screen door can be a standard insect screen door, which can preferably be connected or connected to the clamping device according to the invention via a receiving element, as described above.

It was in the 4a) and 4b) slightly skewed perspective views of the clamping device according to the invention 1 chosen to better understand the Embodiment to allow. Good to see the overall compact design of the illustrated embodiment. Looking from the outside on the frame of a door is essentially only the Z-angle-shaped receptacle 17 with hinge axis 18 and inserted screw 13 to recognize. For this reason, it makes sense the optics of the receiving element 17 appealing, z. B. in the form of plastic, which at the same time also on the corrosion properties of the clamping device according to the invention 1 positively affects. In the embodiment shown, it is such that the first support member 8th with the plastic of the receiving element 17 is overmoulded.

In the 5a and 5b An example of a directional deflector and its operation is shown schematically. For the sake of a better clarity of presentation, only the essential parts for effecting the effect of the clamping device are shown. 5a shows the clamping device 1 in its initial position, in the case of the two support elements 8th and 9 by means of the connecting element comprising the system of screw 13 and mother 14 already connected to each other, but before the system of screw 13 and mother 14 has been actuated to initiate a clamping force. In the area of the front surfaces 11a and 11b the support elements 8th and 9 is the screw 13 through the two coincident openings 12a , b and with the mother 14 , which is located inside the clamping device connected. The two side surfaces 10a and 10b the two support elements 8th and 9 are aligned in the starting position substantially parallel to each other. The distance between their inner surfaces is h. The distance between screw and nut is in the starting position k. An end area 25 of the first support member 8th is orientationally fixed with the Richtungsumlenkelement 23 connected. In the example shown, the Richtungsumlenkelement 23 a pivot bearing, which has an opening for receiving the end portion 25 having. It is possible that the pivot bearing 23 already integral with the first support member 8th is trained. According to one embodiment of the invention, the pivot bearing 23 and the first support member 8th molded in one piece from the same material, for example made of plastic. Preferably, however, it is the case that the pivot bearing 23 and the first support member 8th are constructed of different materials, for. B. the pivot bearing 23 made of a plastic and the support element made of metal. So can both for the pivot bearing 23 as well as for the support element 8th the most appropriate material is selected. The distance k between the screw 13 and the mother 14 is so far reduced that the second support member 9 in light investment with the investment point or investment area 24 of the pivot bearing 23 device.

Now the screw 13 for initiating a clamping force between the two support elements 8th and 9 pressed, so is the screw 13 tightened in the axial direction Z, so shortened by the distance k between the screw 13 and the mother 14 to the distance k '. Here comes the curved area 26 of the second support member 9 in stronger system with the pivot bearing 23 and winds in the investment area 24 around the pivot bearing 23 around. There is a change in orientation between the first support member 8th and second support member 9 , In the example shown, in particular the two side surfaces 10a and 10b the two support elements 8th and 9 tilted or tilted against each other.

However, there are other cross-sectional shapes for the pivot bearing 23 possible. In principle, one is also in the investment area 24 slightly curved or even linear cross-sectional shape possible. Also intermediate stages between a circular segment-shaped cross-section and a mere bevel are conceivable, and it is also possible to provide a screening or even a step-shaped design of the rotary bearing. Curved or rounded variants offer around the investment area 24 around basically the advantage that a change in orientation of the second support member 9 relative to the first support member 8th can be carried out very evenly and in particular does not lead to unwanted closures due to space problems in the construction.

In the illustrated embodiment, in particular, the second support member 9 so stable formed that it is the turning process to the pivot bearing 23 around practically not deformed. However, mechanisms are also conceivable in which the orientation change between the first and second support element 8th respectively. 9 straight on one Deformation of one of the two support elements 8th respectively. 9 is returned.
