Description

The invention relates to a fastening device for plate-shaped Components, according to the preamble of the main claim.

In particular, the invention relates to a fastening device with a fastened to the plate-shaped component Holding element, which by means of at least one of the plate-shaped Component penetrating screw for adjustable fastening a support on the plate-shaped component with a counter-pressure element is clamped.

Such fastening devices are in particular used to glass walls, glass doors, or glass partitions similar, for example, shower enclosures, too Fasten. The attachment takes place either on Hinge hinges or other mounting aids.

The basic problem of such fasteners This is because they must be mountable on site. there It must be possible, the plate-shaped member in his Able to adjust, for example Manufacturing inaccuracies, structural deviations or to be able to correct something similar. A factory pre-assembly usually retires.

The mounting options must be created so that the plate-shaped component safely and without the risk of damage can be installed. This installation should preferably not be very staff intensive and Exclude incorrect installation.

The prior art shows a wide variety of ways to attach plate-shaped components, such as glass panes. Usually this attachment takes place by a clamping,
wherein a screw is passed through a bore or recess of the plate-shaped member and bolted to a carrier. Although such constructions are simple and inexpensive to produce, but they have the decisive disadvantage that the side facing away from the carrier of the plate-shaped member is provided with a counter-pressure plate or the like. This eliminates a simple cleaning. Especially in shower enclosures or the like, this is highly undesirable. It is namely, apart from the increased personal cleaning effort, the risk that form deposits on which attach germs. Thus, it is also required for hygienic reasons, the outer surface of the plate-shaped components completely or as smooth and flat form.

An assembly option in which a cone-shaped retaining element is used, is previously known from EP 841 032 A2. Although the cone-shaped holding element allows a smooth Surface of the plate-shaped component to realize the Assembly and in particular the adjustment of the position of the plate-shaped However, component is relatively expensive, since a rotatable, eccentric adjusting element must be provided. This increases the production costs for the Fastening device quite considerably.

From DE 77 05 090 U, it is known a clamping rail a glass pane to attach, with a countersunk screw passed through the glass plate and with a in the Clamping rail stored mother head is screwed. Of the flush screw in the glass pane allows in the Border area of her head and in the recess for the Actuator the accumulation of dirt.

The invention is based on the object, a fastening device to create the type mentioned, which with a simple structure, cost-effective manufacturability and simple assembly the disadvantages of the prior art avoids and in particular a substantially smooth Outer surface of the plate-shaped component allows.

According to the invention the object is achieved by the features of Main claim solved, the dependent claims show further advantageous Embodiments of the invention.

In the context of the invention is thus provided that the carrier provided for Lagejustierung with a recess for the screw which is the respective lateral adjustment possibility - related to the central axis of the recess of the plate-shaped component - is greater than the respective Diameter of the screw and that the carrier a the Adjusting movement of the counter-pressure element ermöglichende Support surface for the counter-pressure element comprises.

The fastening device according to the invention is characterized through a number of significant benefits. So can be waived according to the invention in particular to provide eccentric adjusting or Counter-pressure elements or holding elements to use! which offer different mounting options, In this way, an adjustment of the position of the to provide plate-shaped component. According to the invention that plate-shaped component rather purely in his desired position be brought that the screw in the essential laterally displaced larger recess of the carrier can be. This shift can be in any radial Directions relative to the central axis of the recess of the Carrier. According to the invention, the extent of possible Adjustment particularly easy selectable, since only the ratio of the outer diameter of the screw to the Diameter of the recess of the wearer to be chosen appropriately got to. Are thus experience only small Justierbewegungen required, so the recess of the Carrier be dimensioned correspondingly smaller. analog applies to required larger adjustment measures.

By the bracing of the retaining element relative to the counter-pressure element by means of the screw is a secure holder guaranteed. Even with a slight solution of the clamping force the screw is prevented that the plate-shaped component it dissolves and falls down. Thus, the inventive Fastening device also a high degree Operational safety.

The counter-pressure element may preferably in the form of a Be formed plate. To the contact pressure on the carrier or the plate-shaped component lead to can, it may be favorable if the counter-pressure element his side facing the wearer with a friction-increasing surface is provided. This can be in Form a corrugation or knurling be formed. By a tightening of the screw will this corrugation or knurling pressed into the surface of the carrier, so that in addition to a frictional holder and a form-fitting Bracket is made.

It is particularly favorable if the carrier with a Recess for receiving the counter-pressure element is provided. This can thus completely or partially in the recess be sunk by the carrier, so that the counter-pressure element not or only slightly above the surface of the carrier protrudes.

In order to meet high visual requirements and can to prevent contamination from entering the area between it is to prevent the back pressure element and the carrier particularly advantageous if a cover is provided, on the counter-pressure element or on the screw fastened and can be applied against the wearer. Alternatively it is It is also possible to attach the cover directly to the carrier fasten, for example, in the recess of the Support in which the counter-pressure element is inserted to lock. The cover may for example consist of a Be made of plastic material, which has a sufficient Elasticity for clipping or pressing in corresponding Mounting recesses has.

The holding element, which is usually made of metal (steel, Stainless steel, brass or similar) can be made in favorable development of the invention with a plastic sheath be either completely on the Outer surface of the holding member is sprayed or covers at least portions of the outer surface. These Plastic coating protects in particular the wall of the Recess of the plate-shaped member and prevents For example, in a glass plate breaking edges or similar. Furthermore, minor Measurement inaccuracies are compensated.

It is particularly advantageous if the plastic casing at least partially has a galvanized surface. It is therefore not necessary, the holding element itself with to provide a surface of high quality, for example polish or chrome. Rather, such a Surface cost-effective and easy at the Plastic material of the plastic casing can be achieved.

To facilitate the assembly, it can continue to be advantageous be, the holding element by means of a clamp or a Press fit in the recess of the plate-shaped component pre-assemble. Again, the plastic sheath be cheap. This can, for example, with Verrastungsnasen or the like. Thus, in the assembly prevents the retaining element from the plate-shaped Component releases and falls down.

The inventive design of the Fastening device allows the threaded hole for To provide Aufnehmung the screw on the holding element. It is thus possible to remove the screw from the outside of the screw plate-shaped component.

The inventive construction can thus both on the well-known eccentric adjustment as well as on constructions be omitted, the slots or the like to the side Provide adjustment. Rather, a Einjustierung the relative position between the plate-shaped member and take the carrier in each direction. Since that Counterpressure element bears completely against the carrier, results in a large touchpad and not just how in the prior art, a point contact.

Another advantage of the construction according to the invention is in that the carrier itself, which part of a Hinge or the like can be, very inexpensive and easy can be configured. As materials are available Aluminum, brass, stainless steel or similar. This also results in very favorable production costs.

Should in the extreme case by the dimensional differences between the outer diameter of the screw and the inner diameter the recess of the wearer provided adjustment not be sufficient, so can in the simplest way the assembler the recess of the carrier by means of a File or similar can be enlarged to the desired To achieve positioning.

The cover or cap described, since they are made Plastic is made, galvanized, such as chrome or in a plastic version with color matching be formed on the installation situation.

Compared to conventional designs arises at the fastening device according to the invention a cost saving in terms of manufacturing costs by more than 60%.

The lower installation and adjustment effort is still here not considered.

The holding element 4 is encapsulated with a plastic casing 10, which, at least on their free top, galvanic can be coated. The sizing of Retaining element 4 and the plastic sheath 10 is so chosen that the holding element 4 completely in the recess the plate-shaped component 1 is receivable (see Fig. 1), so that a completely smooth surface of the plate-shaped component 1 results. By suitable Dimensioning of the plastic sheath 10 is, in related to the cylindrical portion of the recess. 9 or of the holding element 4 a press-fit pre-assembly of the holding element 4 on the plate-shaped component 1 possible.

For mounting thus the carrier 2 against the plate-shaped Component 1 brought into contact. Subsequently, the screw is 3 inserted through the counter-pressure element 5 and into the threaded hole 12 screwed. Now it is possible through lateral relative movement between the plate-shaped Component 1 and the carrier 2 to the desired mounting position achieve. Here, the screw 3 in relation to their outer diameter larger recess 6 moves in time become. The same applies to the possibility of movement of the Counter-pressure element 5 in the larger-sized recess 7. Once the desired mounting position is reached, the Tightened screw 3. A roughened, ribbed or grooved Surface of the counter-pressure element 5 is against the Contact surface of the carrier 2 pressed so that in addition gives a positive fixation.

Hereinafter, a cap-shaped plastic cover 8 in the recess 7 engaged. For holding the recess 7 be provided with an undercut, in which Edge lugs of the cover 8 can be latched.

With regard to the dimensions of the individual components to be selected For example, the screw 3 with an M6 thread be provided. In a thickness of the plate-shaped member. 1 For example, 8 millimeters results in a length of Neck 13 (see Fig. 1) of 4 millimeters. The diameter the recess 6 can, for example, 12 millimeters be selected so that each have a lateral Movement of 3 millimeters can be realized. It understands itself that other dimensions are possible.
