ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a fastening device for plates, in particular glass plates, such as for facades, in particular glass facades, for buildings and other purposes.
This invention relates to a fastening device for fastening a glass panel to a wall, a building-side substructure or similar object using a clamp fitting that grips the glass panel and a holder that is supported on the clamp fitting so that it can swivel to a limited extent in three dimensions.
2. Background Information
The prior art includes holders for glass plates at a point or points that have a boring running through them in which the mobility of the glass plate relative to a support construction is made possible by means of joints or links, the center point of which lies inside the boring through the glass plate. A holder of this type is described in European Patent 0 201 212 B1, for example. The joint thereby makes possible a pivoting or rotational movement, but practically no displacement relative to the plane of the plate.
European Patent 0 655 543 B1 describes a limited pivoting capability of a plate with a hole bored through it, which capability is achieved by the fact that a biconical head of a bolt connected with the support structure is mounted so that it can move in a hollow screw inside the boring through the plate. This biconical head is mounted on the end surface between elastomer discs. This construction is comprised of a large number of parts. It is very complex and expensive to manufacture. The installation of such a holder is time-consuming and can be done from only one side of the plate.
Federal Republic of Germany Patent 198 59 888 A1 describes a system for fastening plate-shaped components that require no recesses in the plate-shaped components for the fastening of the retaining element. For this purpose, in addition to the plate-shaped components, an additional plate-shaped component is added on one side, in which additional plate-shaped component there is a recess through which a retaining element runs. The retaining element thereby sits in a partly conical and partly cylindrical boring inside the plate and a threaded pin runs through the retaining element.
A fastening device for a glass plate with a voltaic element is described in Patent Cooperation Treaty Publication WO 99/63193. In this case, the fastening device is held on a building-side bracket on one side, and on the other side, the glass plate is clamped between two clamping elements. In this device of the prior art, a union cap or coupling cap is supported with adjustable bias on the inside clamp element, whereby between the union cap and the inside clamp element, there is a permanently elastic spring element that allows a relative movement of the union cap with respect to the clamping element. An additional purpose of this device of the prior art is the realization of a plurality of three-dimensional joints between the glass plate and the building-side mounting as well as the realization of the route for the lines that carry electrical cable through the fastening device.
OBJECT OF THE INVENTION
The object of this invention is to create a fastening device in the form of punctiform holders for plates, in particular glass plates, that allows a pivoting or rotational movement and a translation movement of the glass plate within certain limits. This fastening device can also be manufactured economically and used universally, whereby it can also be used with solar modules in a manner that is aesthetically appealing. The fastening device claimed by the invention can also be installed quickly and easily, so that the total costs of facades, roofs, coverings, etc., comprising these plates can be significantly reduced. The fastening devices should be realized so that the connection to a load-bearing or support construction can be made on both sides of the plates. The phrase “both sides of the plates” is also intended to include an external fastening. Finally, the fastening device claimed by the invention includes the punctiform holders for both single glass plates and for laminated glass plates.
SUMMARY OF THE INVENTION
The invention teaches that this object can be accomplished in a fastening device for plates, in particular glass plates, to a building-side mounting, whereby the glass plates have borings or holes all the way through, characterized by the fact that inserted in each boring there is at least one metal annular body with an internal or female thread and an outside facing made of an elastic material positively and non-positively connected with the annular body, and a threaded pin for the connection to a load-bearing construction can be screwed into the annular body.
Additional developments of the teaching of the invention are described herein below in the features of the invention.
The object of the invention can be achieved on the fastening device described above in the form of a punctiform holder in that in each boring through a plate, in this case a glass plate in particular, an annular body is inserted, which annular body has an internal or female thread and an outside facing, covering, or lining made of an elastic material, which material is positively and non-positively connected with the annular body. A threaded pin for the connection to a load-bearing construction or building structure can be screwed into the annular body.
Between the annular body that is located in the boring through the plate, which annular body can be made of metal, and in particular of stainless steel, and the plate there is thus an elastic collar or cuff or an elastic ring which, when it deforms, can absorb all or substantially all of the possible movements of the plate relative to the load-bearing construction or building structure. This elastic facing body has a radial dimension that can be sized so that significant movements between the annular body and the plate can be absorbed essentially without transmitting these movements to the plate. A fastening device of this type can be capable of preserving the elasticity of the glass plates, because it does not substantially restrict the freedom of movement of the glass plates and thus can result in a neutralization of forces. The glass plate is essentially not restricted in its degrees of freedom with respect to the substructure. A fixed clamping, on the other hand, is necessarily rigid and could result in the destruction of the glass plate.
In other possible embodiments of the present invention, the annular body may be constructed of different durable materials than metal, such as plastic, preferably hard plastic.
The annular body has an axial threaded boring running all the way through it, so that the threaded bolt can be screwed in on both sides of the annular body. The elastic facing, on its inside, surrounds the annular body, and on the outside of the elastic facing, it is in contact with the interior wall of the boring that runs through the plate. Thus, the entire space between the annular body and the plate is filled with the elastic facing. As a result of this measure, different movements as described above between the annular body and the plate can be absorbed, including, in particular, pivoting or rotational movements of the plate plane relative to the axis of the annular body, a displacement of the plate plane parallel or diagonal to the axis of the annular body, and a displacement of the plate perpendicular to the axis of the annular body (e.g. thermal expansion of the plate, wind and snow loads on the plate). The punctiform holder claimed by the invention can therefore be suitable for the overhead and load-bearing attachment of plates, in particular glass plates, for example of the type used for coverings and roofs, as well as for the attachment of vertical load-bearing constructions such as glass facades or solar modules.
Further, the elastic component of the fastening device allows for compensation for different external forces, such as wind, snow, heavy rain, thermal expansion and contraction, and other environmental factors, ex
