Description

[0001] The invention relates to a system, a clamping device, and a method for fastening and / or vertically aligning a plate-shaped element, such as a glass plate in a plate holder. The system allows a plate or glass plate to be mounted vertically, i.e., cantilevered from the plate holder as a railing or balustrade, i.e., parallel to the direction of gravity. However, the system can also be used, for example, for room dividers, stair railings, and safety barriers. The system can be used, for example, to firmly anchor the plate to the floor.

[0002] Systems for supporting railing panels are known from the prior art. EP 2 896 764 B1 describes a system for supporting railing panels which also allows the vertical inclination of the railing panel to be adjusted. The background to this is that it is desirable to arrange the railing panel as perpendicular to the earth's horizontal as possible. To this end, EP 2 896 764 B1 proposes fastening a railing panel, which is inserted into a panel holder formed by a retaining profile or embedded or incorporated into a building structure, to the panel holder using clamping parts. The clamping parts are inserted into the panel holder on the side of the railing panel facing away from a pivot point in order to brace the railing panel and adjust its vertical inclination. The clamping parts can be wedge-shaped and have a wedge shape adapted to the clamping gap. The selection and installation of suitable clamping parts can be quite laborious.

[0003] DE 10 2006 028 766 A1 proposes a holding device in which the glass pane is also vertically adjustable. The glass pane is inserted into a U-shaped support rail, which in turn is arranged in a U-shaped receiving profile. The panel can be pivoted vertically via an adjustment device on the underside of the U-shaped support rail.

[0004] WO 2011 / 095779 A2 describes several designs of a plate holding and adjustment mechanism which provides fastening elements on both sides of the plate which, by means of adjustable screws and utilising a wedge effect, can clamp and vertically align the plate arranged therebetween.

[0005] EP 1 818 476 A1 relates to a fastening system for a glass panel, wherein the glass panel is inserted into a U-profile and clamped between a wall of the U-profile and a wedge. The wedge can be adjusted using a screw, pressing it against the glass panel.

[0006] Another system in which the glass plate inserted into a U-profile can be clamped between two parts is shown in DE 20 2013 104 330 U1.

[0007] The invention is based on the object of providing a system, a clamping device for such a system and a method for fastening a plate-shaped element, such as a glass plate, in a plate holder, which allow quick and easy assembly.

[0008] The object is achieved with the system according to claim 1, the clamping device according to claim 8 and the method according to claim 12. Advantageous further developments emerge from the dependent claims, the description and the figures.

[0009] The system for fastening a plate-shaped element comprises at least one plate holder and a clamping device for clamping the plate-shaped element. Optionally, the system can further comprise a support profile, which forms a support for the plate-shaped element and is inserted into the plate holder. Further optionally, covers or seals can be provided, which can be arranged on one or both sides of the plate-shaped element to cover the gap between the plate holder and the plate-shaped element or to create a seal between the plate-shaped element and the plate holder.

[0010] The panel support can, for example, be a U-profile or a U-profile rail that can be attached to a building component, such as a floor, by screwing, gluing, or embedding. Alternatively, the panel support can be formed by the structure itself.

[0011] The particularly rail-shaped or elongated plate holder has two side walls between which the plate-shaped element is inserted or can be inserted. The side walls can be connected via a connecting section of the plate holder, which preferably forms a bottom side of the plate holder. When the plate-shaped element is inserted into the plate holder, it can be supported directly or indirectly on the connecting section. The connecting section can, for example, absorb the weight or substantially the weight of the plate-shaped element.

[0012] The side walls can be arranged parallel or approximately parallel to each other and protrude at right angles or approximately at right angles from the connecting section. The connecting section and the side walls can, for example, form a U-shaped profile rail that is open on one side, particularly on the side from which the plate-shaped element is inserted into the plate holder, i.e., on the top side.

[0013] A first gap, into which the clamping device can be inserted or is inserted, can be formed between a first side wall of the panel holder and the panel-shaped element inserted therein. For example, several such clamping devices can be arranged along the length of the panel holder, in particular at specific distances from one another. A second gap can be formed between the second side wall of the panel holder and the panel-shaped element, which allows the support profile to be inserted into the panel holder and / or permits a tilting movement of the panel-shaped element for its vertical alignment.

[0014] A support for the plate-shaped element is arranged on one of the side walls, in particular the second side wall. The support can be formed by the second side wall or by the support profile, which can be supported, for example, on the second side wall. The side surface of the plate-shaped element facing the second side wall can be supported on the support. The support is preferably convex in shape, so that it touches the side wall of the plate-shaped element, in particular in a linear manner, and allows a tilting movement of the plate-shaped element for its vertical adjustment.If the support is formed by a support profile, it can be provided on a leg of the support profile, which preferably lies flat against the second side wall, wherein there is a gap between the leg and the side surface of the plate-shaped element, which allows the tilting movement for adjusting the vertical alignment of the plate-shaped element.

[0015] Furthermore, a second support can be provided in addition to the above-mentioned first support, on which the plate-shaped element is supported vertically with a weight force. The second support can be formed by the connecting section or the support profile, in particular a second leg of the support profile. The second leg can bear against the connecting section. The second support can be designed to be convexly curved, so that an end face, in particular a lower end face, of the plate-shaped element bears against the second support, in particular in a linear manner. Such a design of the second support ensures that the plate-shaped element rests with its end face on the second support even in a tilted position, whereby loading of an edge of the plate-shaped element, which increases the risk of damage to the plate-shaped element, can be avoided.

[0016] The support profile can be made of plastic, such as ABS, for example. This prevents damage to the plate-shaped element when it is pressed against the support.

[0017] The clamping device has at least one eccentric element, for example a first eccentric element and a second eccentric element. The first eccentric element and / or the second eccentric element can each be designed as an eccentric bolt. The at least one eccentric element can be adjustable by rotation about a respective axis of rotation of the eccentric element such that the plate-shaped element is clamped between the first support and the clamping element and / or tilted with respect to the first support or a rotation axis of the eccentric element. By using at least one eccentric element for clamping and tilting or aligning the plate-shaped element, assembly is simplified and the time required for assembly is reduced. By using an eccentric element, only adjustment movements of the eccentric element that are less than one revolution, in particular less than or equal to 180°, are required for alignment and / or fastening.This allows the fastening and alignment of the plate-shaped element to be carried out quickly and safely.

[0018] For example, a first eccentric element can be provided for the function of clamping the plate between the clamping device and the first support. Alternatively or additionally, a second eccentric element can be provided, which is intended for the vertical alignment of the plate-shaped element. In designs with a first and second eccentric element, the clamping and alignment functions can be largely decoupled. This represents an advantage over prior art designs in which alignment and clamping are accomplished with a wedge. In the prior art, the wedge(s) must be selected and / or used in such a way that alignment occurs simultaneously with clamping. This increases the assembly effort.

[0019] The clamping device can have a first eccentric element, in particular an eccentric bolt, with a first axis of rotation and at least one eccentric surface, wherein rotation of the first eccentric element about the first axis of rotation causes the plate-shaped element to be clamped between the support and the clamping element. The at least one eccentric surface of the first eccentric element can be supported on the first side wall of the plate holder. During rotation of the first eccentric element, the at least one eccentric surface can slide on the first side wall, whereby a spreading force between the first side wall and the plate-shaped element can be increased or decreased depending on the direction of rotation. As the spreading force increases, the force with which the plate-shaped element is clamped between the support and the clamping device increases.For example, rotation of the first eccentric element in a first direction of rotation can increase the clamping force and / or spreading force, and rotation in a second direction of rotation opposite to the first direction of rotation can reduce the clamping or spreading force.

[0020] The system, in particular the clamping device, can comprise a pressure piece which forms at least one, for example two, support surfaces and supports the first eccentric element so as to be rotatable about the first axis of rotation. The at least one support surface is configured such that it can be supported on the first side wall of the plate holder. In particular, the at least one eccentric surface and the at least one support surface can be supported on the first side wall. The clamping device or the system is configured such that rotation of the first eccentric element about the first axis of rotation causes the pressure piece to be rotated about a second axis of rotation and to be supported on the first side wall with the at least one support surface, in particular to be pressed against the first side wall by rotation of the first eccentric element.It is preferred that the rotation of the first eccentric element, on the one hand, causes its at least one eccentric surface to be pressed against the first side wall, whereby the at least one support surface of the pressure piece is also pressed against the first side wall. The second axis of rotation can, for example, be arranged between the first axis of rotation and the support surface and / or parallel to the first axis of rotation. The pressure piece can therefore act in the manner of a rocker or a lever, wherein the rotation of the first eccentric element presses the first axis of rotation away from the first side wall, whereby the first eccentric element exerts a force pointing from the first side wall onto the pressure piece, which force is transmitted to the at least one support surface via the rotatability of the pressure piece about the second axis of rotation and in the process presses the at least one support surface against the first side wall.The reaction force exerted on the component forming the second axis of rotation corresponds to the force with which the plate-shaped element is pressed against the first support. The component forming the second axis of rotation can, for example, be the second eccentric element.

[0021] In further developments, the first eccentric element can have two eccentric surfaces spaced apart from one another in the direction of the first axis of rotation, in particular connected via a shaft, which each extend at least partially over the circumference of the first eccentric element and are arranged eccentrically to the first axis of rotation. The shaft can be mounted on the pressure piece so as to be rotatable about the first axis of rotation. For this purpose, the pressure piece can have one or more bearing surfaces for supporting the shaft of the first eccentric element. The at least one bearing surface can encompass the preferably cylindrical shaft at least partially over the circumference.

[0022] The spaced-apart arrangement of the eccentric surfaces of the first eccentric element allows for secure support of the eccentric element or its eccentric surfaces on the side wall. This reduces the risk of the first eccentric element tilting relative to the side wall.

[0023] The two eccentric surfaces of the first eccentric element can be arranged in phase with each other or not out of phase. This ensures that the first axis of rotation is displaced parallel during rotation of the first eccentric element, but at least not tilted. The two eccentric surfaces of the first eccentric element can be designed essentially identically.

[0024] The second eccentric element, in particular a second eccentric pin, can have a second rotation axis and at least one eccentric surface. The second eccentric element is adjustable such that rotation of the second eccentric element about the second rotation axis causes the plate-shaped element to be tilted relative to the support or a pressure plate of the holding device relative to the second rotation axis. The plate-shaped element can be aligned with respect to its vertical position using the second eccentric element. The first and second rotation axes are preferably parallel to one another.

[0025] In further developments, the second eccentric element can have two eccentric surfaces spaced apart from one another in the direction of the second axis of rotation, each extending at least partially over the circumference of the second eccentric element and arranged eccentrically to the second axis of rotation. The spaced arrangement of the eccentric surfaces ensures secure support of the eccentric surfaces on the part, such as a pressure plate of the clamping device, against which the eccentric surfaces rest. The pressure plate, which is preferably arranged parallel to the plate-shaped element, can transmit the tilting movement caused by rotation of the second eccentric element from the pressure plate to the plate-shaped element.

[0026] Preferably, the two eccentric surfaces are arranged out of phase with respect to one another. This results in a tilting movement of the printing plate with respect to the second axis of rotation or the tilting movement of the plate-shaped element with respect to the first support. For example, the two eccentric surfaces can be arranged out of phase with respect to one another by half a revolution of the eccentric element or by 180°. Alternatively, the two eccentric surfaces can be arranged out of phase by an angle of less than 180° or less than 120°, such as 90°. This can ensure that a rotation of the second eccentric element in a first direction of rotation, such as by 90° or less than 90°, such as 45°, causes a tilting of the printing plate about a tilting axis that runs transversely to the second axis of rotation. Likewise, a rotation of the second eccentric element in a second direction of rotation opposite to the first direction of rotation, such as by 90° or less than 90°, such as45°, a tilting of the pressure plate around the tilting axis in a second tilting direction, opposite to the first tilting direction, can be achieved. Furthermore, it is possible that in a neutral position, from which the eccentric element can be rotated by 90° or 45° in the first direction of rotation or by 90° or 45° in the second direction of rotation, the pressure plate is parallel or approximately parallel to the second axis of rotation.

[0027] Optionally, one or more projections acting as rotation stops can be provided on the second eccentric element, which limit the rotatability of the eccentric element in the first and second rotational directions by abutting one or more stop surfaces, which are formed, for example, by the pressure piece. A first projection can abut a first stop surface of the pressure piece when the second eccentric element is rotated in the first rotational direction, and a second projection can abut a second stop surface of the pressure piece when the second eccentric element is rotated in the second rotational direction. Between these two stop positions, the second eccentric element can be rotated back and forth through an angle that can be less than or equal to 180°, less than or equal to 120°, or less than or equal to 90°.

[0028] The pressure piece and the first and second eccentric elements can be arranged on one side of the pressure plate. The pressure plate preferably has at least one holding element, such as arms or snap arms, which holds the pressure piece, in particular captively, on the pressure plate, in particular in such a way that the pressure plate can be tilted in the first and second tilting directions with respect to the pressure piece or the second axis of rotation about the tilting axis. This advantageously ensures that the parts of the holding element can be handled as a unit. Advantageously, the first and second eccentric elements are also held captively on the clamping device, in particular on the pressure piece.

[0029] In further developments, the clamping device can have a compensator plate on the side facing the plate-shaped element, which is preferably fastened, in particular detachably fastened, to the pressure plate. The compensator plate, preferably made of plastic, such as ABS, serves to bear against the plate-shaped element and to compensate for a gap between the pressure plate and the plate-shaped element. This allows the system to be used with different thicknesses of the plate-shaped element, such as different glass plate thicknesses, without any adjustments to the components of the system, in particular the clamping device, apart from the compensator plate. Different compensator plates can be provided for different thicknesses of the plate-shaped element, whereby the compensator plate suitable for the thickness of the plate-shaped element to be used is fastened to the pressure plate.For example, the compensator plate can be slid onto the pressure plate. For example, the compensator plate can have grooves facing each other on two opposite sides, which engage around opposite edges of the pressure plate or can be slid onto the pressure plate along these edges.

[0030] The at least one eccentric element, in particular the first and second eccentric element, can each have, in particular on the end face, a driving profile with which a tool can be brought into engagement and with which the eccentric element can be rotated about its axis of rotation. The driving profile is designed such that a torque applied by the tool can be transmitted to the respective eccentric element. The driving profile can be, for example, a hexagon socket profile, an internal multi-tooth profile, an internal multi-round profile or the like. Preferably, the driving profile or the end face of the at least one eccentric element points towards the top side or the open side of the plate holder. This makes the driving profile accessible for coupling and rotating by means of the tool. The first axis of rotation and the second axis of rotation can extend vertically from the underside to the top side of the plate holder.extend in the direction from which the plate-shaped element protrudes from the plate holder. This allows for particularly easy access to the drive profile and adjustability of the respective eccentric element from the top of the plate holder.

[0031] In further developments, the shaft of the first eccentric element can have a structured, in particular grooved, surface, wherein the structured surface interacts positively with the bearing surface of the pressure piece in which the shaft is mounted, such that the positive locking can be overcome by rotating the first eccentric element about the first axis of rotation. This ensures that the first eccentric element is generally rotatable about its axis of rotation, but accidental release is prevented by the positive locking. In particular, the bearing surface of the shaft and the pressure piece can each have coordinated structured surfaces, which interact positively such that the positive locking can be overcome by rotating the first eccentric element about the first axis of rotation.

[0032] The invention also relates to a method for fastening the plate-shaped element in the plate holder, wherein a clamping device as described herein is inserted between the plate-shaped element and a wall, in particular the first wall of the plate holder. Optionally, before inserting the clamping device, a compensator plate suitable for the thickness of the plate-shaped element used can be selected and attached to the pressure plate of the clamping device. After inserting the clamping device, at least one eccentric element of the clamping device is rotated, for example by means of the tool, whereby the plate-shaped element is clamped between the clamping device and the support and / or is tilted in particular for aligning the plate-shaped element with respect to the support. The at least one eccentric element can comprise a first eccentric element which can be rotated, for example by means of the tool, about its axis of rotation, i.e.the first axis of rotation is rotated, whereby the plate-shaped element is clamped between the clamping device and the support. Preferably, the first eccentric element is rotated by an angle that is less than or equal to 180°. Alternatively or additionally, the at least one eccentric element can comprise a second eccentric element that is rotated about the second axis of rotation, for example by means of the tool, whereby the plate-shaped element is tilted with respect to the support or the pressure plate with respect to the second axis of rotation about a tilting axis that is transverse to the second axis of rotation. Preferably, the second eccentric element is rotated in particular from a neutral position in which the pressure piece is parallel or approximately parallel to the second axis of rotation, at an angle in a first direction of rotation or a second direction of rotation whose magnitude is less than or equal to 90°.

[0033] In embodiments with a first eccentric element and a second eccentric element, it is preferred that first the first eccentric element is rotated, then the second eccentric element is rotated and then the first eccentric element is rotated again.

[0034] In particular, the first eccentric element can be rotated until a first torque is reached. The second eccentric element can then be rotated, in particular by an angular amount less than or equal to 90°, in one of the two directions of rotation to align the plate-shaped element. The first eccentric element is then rotated further, in particular in the direction in which it was initially rotated, until a second torque is reached that is greater than the first torque. To control the torque, an appropriate tool, such as a torque wrench, can be used, which can be coupled to the driving profile of the respective eccentric element. Optionally, before inserting the clamping device, a support profile, in particular the support profile described herein, which forms the support about which the plate-shaped element can be tilted, can be inserted into the plate holder.Subsequently, the plate-shaped element can be placed on the support profile, in particular the second support, wherein, when the plate-shaped element is placed on the second support or in the plate holder, it protrudes from the plate holder.

[0035] After the plate-shaped element has been clamped and aligned using the clamping device, the gap at the top of the plate holder, formed between the plate and the first side wall of the plate holder, can be closed at the top with a cover to prevent the ingress of dirt or water and access to the clamping device. The cover also serves an aesthetic purpose.

[0036] The invention has been described using several exemplary embodiments. Embodiments of the invention are described below with reference to figures. The features disclosed therein advantageously develop the subject matter of the claims, individually and in any combination of features. They show: Figure 1 shows a cross-section through the components of the system according to the invention. Figure 2 shows a perspective view of a support profile and a clamping device in a first embodiment. Figure 3 shows a perspective view of a pressure piece of the first embodiment. Figure 4 shows a perspective view of a pressure plate of the first embodiment. Figure 5 shows a side view and a perspective view of a first eccentric element of the first embodiment.

Figure 9 shows a perspective view of a pressure plate of the second embodiment. Figure 10 shows a perspective view of a compensator plate of the second embodiment.Figure 11 shows a side view and a perspective view of a first eccentric element of the second embodiment, Figure 12 shows a side view and a top view, a side view rotated by 90° thereto and a top view and a perspective view of a second eccentric element of the second embodiment, and Figures 13a to 13c show schematic diagrams similar to the view from , Figure 1 , in which tilting and vertical alignment of a plate-shaped element by means of a clamping device are illustrated.

[0037] The Figure 1 shows a sectional view through a system 1 transverse to the longitudinal direction of a rail-shaped or elongated plate holder 3. With the system 1, a plate-shaped element 2, hereinafter referred to as glass plate 2, such as a parapet plate made of glass, can be accommodated and adjusted with respect to its vertical alignment, as shown in the Figures 13a to 13cThe components of the system 1 provided for fastening and aligning the plate 2 are the plate holder 3, a first support 41, which in this example is formed by a support profile 40, and a clamping device 10, which can be designed, for example, according to the first and second embodiments described below.

[0038] In the example shown, the panel holder 3 is a U-profile rail that can, for example, be embedded in the floor of a building or screwed to the floor of the structure. The panel holder 3 has a first side wall 6 and a second side wall 7, which are connected by means of a connecting section 8 of the panel holder 3. The connecting section 8 forms the underside of the panel holder 3. The side wall 6 or the connecting section 8 can have holes in each of which a screw can be received, which is or will be anchored in the building in order to fasten the panel holder to the building. The side wall 6 or the connecting section 8 can be clamped between the building and a screw head or a screw nut.

[0039] At its top, the panel holder 3 has an opening formed between the first side wall 6 and the second side wall 7, through which the glass panel 2 can be inserted into the panel holder 3. When inserted, the glass panel 2 protrudes from the panel holder 3 through the opening on the top and can, for example, form a parapet or railing in or on a building. The system 1 can advantageously be used to attach a (balcony) railing or a parapet made of glass panels.

[0040] A first gap formed between the glass plate 2 and the first side wall 6 can be covered at the top by means of a cover 5. In the example shown, the cover 5 is placed on the leg of the plate holder 3 forming the side wall 6. The second gap formed between the glass plate 2 and the second side wall 7 can be covered with a cover 4. The cover 4 is in the Figure 1In the example shown, a seal that prevents water from penetrating the second gap. The cover 4 lies sealingly against the glass plate 2 and the second side wall 7. The cover 4 comprises a sealing lip that rests against the glass plate and is designed in the form of a groove to direct running water away from the glass plate 2. Furthermore, the seal 4 comprises a plurality of slats that extend in particular in the longitudinal direction of the plate holder 3, which also rest sealingly against the glass plate 2 and are arranged below the area where the sealing lip rests on the glass plate 2. The slats can prevent water that could not be drained away by the sealing lip from penetrating the second gap. The cover 5 can have a fixed part that is slipped onto the side wall 6, and a seal 5a fastened thereto, which prevents water from penetrating the first gap.The seal 5a can - like the cover 4 - have a sealing lip which is designed in the form of a groove and rests against the glass plate 2, and / or slats which rest sealingly against the glass plate 2.

[0041] Before inserting the glass plate 2, the Figure 1 In the example shown, a support profile 40 is inserted into the panel holder 3, which forms at least a first support 41 and preferably a second support 42. The support profile 40 has a first leg 43, which forms the first support 41, and a second leg 44, which forms the second support 42. The first and second legs 43, 44 are arranged at an angle to one another—in the example shown, at an obtuse angle, alternatively at a right angle—and form an L-shaped profile in cross-section.

[0042] The first support 41 has a convex surface in cross-section, which extends in the longitudinal direction of the plate holder 3. The first leg 43 rests, in particular, flat against the second side wall 7. The second side wall 7 prevents the first support from being pushed sideways.

[0043] The second support 42 has a convex surface in cross-section, which extends along the longitudinal direction of the plate holder 3. The second leg 44 rests in particular flat against the connecting section 8. Although the first support 41 and / or the second support 42 can be formed by the plate holder 3, in particular the U-profile rail, it is advantageous to provide a support profile 40 separate from the plate holder 3, since on the one hand it is easier to manufacture and on the other hand it can be formed from a different material than the plate holder 3. The plate holder 3 can, for example, be formed from a metal or a metal alloy, wherein the support profile 40 can be made from a plastic, such as ABS (acrylonitrile butadiene styrene copolymer), or another suitable plastic.By forming the support profile 40 from plastic, damage to the glass plate 2 can be prevented when it is clamped between the clamping device 10 and the first support 41 and / or inserted into the plate holder 3 and placed on the second support 42.

[0044] After inserting the support profile 40 into the plate holder 3, the glass plate 2 is inserted into the plate holder 3, in particular such that a lower end face at the lower end of the glass plate 2 rests on the second support 42 and a side face of the glass plate 2 rests against the first support 41. A gap is also formed between the leg 43 and the side face of the glass plate 2. The gap and the convex shape of the first support 41 and / or the second support 42 allow the glass plate 2 to be tilted to a certain extent and aligned vertically. The convex shape of the second support 43 prevents edge loading of the glass plate 2, which could lead to damage.

[0045] After the glass plate 2 has been inserted into the plate holder 3, one or more clamping devices 10, which are designed, for example, according to the first or second embodiment, are inserted into the first gap between the glass plate 2 and the first side wall 6. Before inserting the at least one clamping device 10, one of several compensator plates 12 of different thicknesses, in particular depending on the thickness of the glass plate 2, can be selected and attached to a pressure plate 11 of the clamping device 10.

[0046] Figure 2 shows a perspective view of the clamping device 10 and the support profile 40 according to a first embodiment. The individual parts of this clamping device 10 are shown in the Figures 3 to 6 shown. Figure 7 shows a perspective view of the clamping device 10 and the support profile 40 according to a second embodiment. The individual parts of this clamping device 10 are shown in the Figures 8 to 12The first and second embodiments differ particularly in the design of the first and second eccentric elements 20, 30 and in material-saving measures on the support profile 40, the compensator plate 12, and the pressure plate 11.

[0047] The clamping device 10 has a pressure plate 11, on the side of which facing the glass plate 2 the compensator plate 12 is attached. The compensator plate 12 has a groove 13 on its top and bottom sides, into which an elongated engagement element 14, which extends along the top and bottom edges of the pressure plate 11, engages. The grooves 13 and the engagement element 14 are adapted such that the compensator plate 12 can be slid onto the pressure plate 11 along the elongated engagement elements 14 and, in the slid-on state, is held captively on the pressure plate 11. The compensator plate 12 is preferably made of plastic, although the pressure plate can be made of metal or a metal alloy, for example. The compensator plate 12 rests, in particular flatly, against the side surface of the glass plate 2 facing the first side wall 6.

[0048] The printing plate 11 from Figure 9In contrast to the printing plate 11 Figure 2 , which forms a closed, particularly rectangular, surface, has one or more recesses that serve to save material. The printing plate made of Figure 9 has an upper pressure bar and a lower pressure bar, which extend parallel to the engagement element 14 on the top and bottom and / or form the engagement element 14 on the top and bottom. The upper and lower pressure bars are connected by means of at least one web, which in the example shown has at least one retaining element 17. In the example shown, the recesses are formed to the left and right of the web between the upper and lower pressure bars.

[0049] The compensator plate 12 made of Figure 10 In contrast to the compensator plate 12, Figure 4, which forms a closed, in particular rectangular, surface, one or more recesses that serve to save material. The compensator plate 12 has an upper pressure bar and a lower pressure bar, which extend parallel to the groove 13 on the top and bottom and / or form the groove 13 on the top and bottom. The upper pressure bar of the compensator plate 12 rests on the upper pressure bar of the pressure plate 11 and the lower pressure bar of the compensator plate 12 rests on the lower pressure bar of the pressure plate 11. The pressure bars are connected by means of at least one web, which in the example shown has at least one holding element 17. The recesses can be formed to the left and right of the web between the upper and lower pressure bars. In the Figure 10In the example shown, a recess is formed between two webs and between the pressure beams, creating a closed frame that surrounds the recess.

[0050] On the side of the pressure plate 11 facing away from the compensator plate 12 or facing the first side wall 6, the clamping device 10 has a first eccentric element 20, a second eccentric element 30 and a pressure piece 50.

[0051] The pressure piece 50 is captively attached to the pressure plate 11. For this purpose, the pressure plate 11 has two retaining elements 17, between which the pressure piece 50 is inserted and which securely hold the pressure piece 50 to the pressure plate 11. In particular, the retaining elements 17 encompass or hold the pressure piece 50, in particular connecting webs 55 of the pressure piece 50, such that the pressure piece 50 can perform tilting and rotating movements with respect to the pressure plate 11, at least to a certain extent.

[0052] The pressure piece 50 has a first lever arm 51 and a second lever arm 52, which are connected via two connecting webs 55. The pressure piece 50, in particular the lever arms 51, 52, each have a bearing surface 54a, 54b for the second eccentric element 30 ( Figures 3 and 12 ).

[0053] In the first embodiment, the bearing surfaces 54a, 54b encompass a shaft 31 of the second eccentric element 30 over part of the circumference, in particular around approximately half the circumference of the shaft 31. The shaft 31 and the pressure piece 50 are rotatable relative to one another about a second axis of rotation 37, which corresponds to the longitudinal axis of the shaft 31. The second eccentric element 30 is arranged between the pressure plate 11 and the pressure piece 50. For example, this also ensures that the second eccentric element 30 is held captively in the clamping device.

[0054] The second eccentric element 30 ( Figure 6) has the shaft 31 and a head at each end, which forms a first eccentric surface 32a and a second eccentric surface 32b, respectively. The first eccentric surface 32a and the second eccentric surface 32b are each arranged eccentrically to the rotational axis 37. As shown in Figure 6As can be seen, the first eccentric surface 32a and the second eccentric surface 32b are 180° out of phase with each other about the second axis of rotation 137. The degree of eccentricity, i.e. the distance e 2 , e 3 of the eccentric axis 38a of the first eccentric surface 32a and the eccentric axis 38b of the second eccentric surface 32b from the axis of rotation 37, is equal in amount, but the eccentric axes 38a and 38b are offset in opposite directions from the axis of rotation 37. At least in the installed state of the clamping device 10, the first eccentric surface 32 and the second eccentric surface 32b bear against the pressure plate 11. A rotation of the second eccentric element 30 about the second axis of rotation 37 causes a tilting of the pressure plate 11 with respect to the axis of rotation 37 and thus of the glass plate 2 with respect to the first support 41.

[0055] In the second embodiment, the second eccentric element 30 also has a shaft 31 having a first collar and a second collar which have a larger diameter than the shaft 31. In the Figure 12In the example shown, the second eccentric element 30 has the shaft 31 and, at both ends, the first and second collars, which are in particular designed as heads. The circumference of the first collar is composed of a first eccentric surface 32a and a first bearing section surface 32c, which each extend partially over the circumference. The circumference of the second collar is composed of a second eccentric surface 32a and a second bearing section surface 32c, which each extend partially over the circumference. The shell-shaped first bearing surface 54a encompasses the first bearing section surface 32c of the second eccentric element 30 over part of the circumference. The shell-shaped second bearing surface 54b encompasses the second bearing section surface 32c of the second eccentric element 30 over part of the circumference.The second eccentric element 30 and the pressure piece 50 are mounted relative to one another via the mounting of the bearing section surfaces 32c, 32d on the bearing surfaces 54a, 54b, for example, about a second rotation axis 37 corresponding to the longitudinal axis of the shaft 31. The second eccentric element 30 is arranged between the pressure plate 11 and the pressure piece 50. This also ensures, for example, that the second eccentric element 30 is held captively in the clamping device.

[0056] The first eccentric surface 32a and the second eccentric surface 32b are each arranged eccentrically to the rotational axis 37 and have a less pronounced curvature than the bearing section surfaces 32c, 32d. The bearing section surfaces 32c, 32d can extend concentrically around the second rotational axis 37. The bearing section surfaces 32c, 32d can extend around the circumference by an angle greater than or equal to 180°, wherein the eccentric surfaces 32a, 32b can extend around the rotational axis 37 by an angle less than 180°. In the two transitions of the bearing section surface 32c, 32d to the eccentric surface 32a, 32b, the circumference has a greater curvature than the bearing section surface 32c, 32d and the eccentric surface 32a, 32b (see the top views in Figure 12 ).

[0057] In particular, the distance of the first eccentric surface 32a to the longitudinal axis of the shaft 31 is less than the distance of the first bearing section surface 32c to the longitudinal axis of the shaft 31 and / or the distance of the second eccentric surface 32b to the longitudinal axis of the shaft 31 is less than the distance of the second bearing section surface 32d to the longitudinal axis of the shaft 31. The distances of the first eccentric surface and the second eccentric surface from the longitudinal axis of the shaft or second rotational axis 37 can be equal. As in Figure 12 As can be seen, the first eccentric surface 32a and the second eccentric surface 32b are phase-shifted from one another by an angle about the second axis of rotation 37 which is less than 180°, such as 90°.

[0058] The degree of eccentricity, ie the distance e 2 , e 3 of the eccentric axis 38a of the first eccentric surface 32a and the eccentric axis 38b of the second eccentric surface 32b from the axis of rotation 37 is equal in amount, but the eccentric axes 38a and 38b are offset in opposite directions from the axis of rotation 37.

[0059] At least in the installed state of the clamping device 10, at least one of the first and second eccentric surfaces 32a, 32b rests against the pressure plate 11. A rotation of the second eccentric element 30 about the second rotation axis 37 causes a tilting of the pressure plate 11 with respect to the rotation axis 37 and thus of the glass plate 2 with respect to the first support 41 (see Figures 13a to 13c ).

[0060] By arranging the first eccentric surface 32a and the first bearing section surface 32c to form a common circumference on the first collar and the second eccentric surface 32a and the second bearing section surface 32d to form a common circumference on the second collar, shear forces under load are avoided, as they occur in the design from Figure 5 can occur in which the bearing section surfaces 32a, 32b are arranged offset from the bearing section surfaces (structured surfaces 23a, 23b) along the rotation axis 37. By avoiding shear forces, material and installation space can be saved in the design of the second eccentric element 30.

[0061] The second eccentric element 30 has at least one projection 39a, 39b, which limits the rotatability of the second eccentric element 30 in the first direction of rotation and / or in the opposite second direction of rotation, for example in that the at least one projection abuts against a stop surface of the pressure piece 50, in particular limited in such a way that the second eccentric element 30 can only be rotated back and forth by an angle which is less than 180° or less than 120° or is approximately 90°, as in connection with the second embodiment in Figure 12 is shown. If such at least one projection 39a, 39b is optionally provided on the second eccentric element 30 of the first embodiment, the rotatability of the second eccentric element can be limited to an angle of less than or equal to 180°.

[0062] Specifically, a first projection 39a is formed on the circumference of the shaft 31 and / or on the underside of the first collar. Alternatively or additionally, a second projection 39b is formed on the circumference of the shaft 31 and / or on the top side of the second collar. The first projection 39a limits the rotatability of the second eccentric element 30 in a first direction of rotation by abutting a first stop surface of the pressure piece 50. The second projection 39b limits the rotatability of the second eccentric element 30 in a second direction of rotation by abutting a second stop surface of the pressure piece 50. Between the positions in which the projections 39a, 39b abut their stop surfaces, the second eccentric element can be rotated back and forth by the angles specified above.By limiting the rotatability, it is prevented that the second eccentric element 30 is rotated into an impermissible position in which, for example, the clamping function of the clamping device 10 is not ensured or not properly ensured.

[0063] The pressure piece 50 of the first and second embodiments, in particular the first lever arm 51 and the second lever arm 52, each have a bearing surface 53a, 53b. A shaft 21 of a first eccentric element 20 is rotatably mounted on the bearing surfaces 53a, 53b about a first rotation axis 27.

[0064] The first eccentric element 20 of the first embodiment ( Figure 5) has a head (collar) at each of its ends, each of which has a larger diameter than the shaft 21 and forms a first eccentric surface 22a and a second eccentric surface 22b, respectively. The sections of the shaft 21 that support the first eccentric element 20 for rotation about the first axis of rotation 27 are arranged between the head and the collar in the first embodiment.

[0065] The first eccentric element 20 of the second embodiment ( Figure 11 ) has a first collar and a second collar, each having a larger diameter than the shaft 21 and forming the first eccentric surface 22a and the second eccentric surface 22b, respectively. The first collar and second collar are spaced apart from one another along the rotation axis 27 and, in contrast to the first embodiment, are arranged between the sections of the shaft 21 that support the first eccentric element 20 for rotation about the first rotation axis 27.

[0066] The two eccentric surfaces 22a, 22b are not out of phase with each other, or in phase with each other. The degree of eccentricity, i.e., the distance e 1 of the eccentric axes 28a, 28b of the eccentric surfaces 22a, 22b from the rotation axis 27, is equal. The eccentric axes 28a, 28b are offset in the same direction with respect to the rotation axis 27.

[0067] When the clamping device 10 is inserted, the eccentric surfaces 22a, 22b can rest against the first side wall 6 of the plate holder 3. When the first eccentric element 20 is rotated about its first rotational axis 27, the eccentric surfaces 22a, 22b slide along the first side wall 6, whereby the first rotational axis 27 is moved away from the first side wall 6 or toward the second side wall 7, depending on the direction of rotation. The pressure piece 50 is thereby rotated about the second rotational axis 37.

[0068] The pressure piece 50, in particular the first lever arm 51 and the second lever arm 52, have support surfaces 57a, 57b, which in the example shown are structured, in particular grooved. The second axis of rotation 37 is arranged between the support surfaces 57a, 57b and the bearing surfaces 53a, 53b. This causes the support surfaces 57a, 57b to be moved toward the first side wall 6 or pressed against the side wall 6 when the first eccentric element 20 is rotated in a direction that moves or presses the first axis of rotation 27 or the shaft 21 away from the side wall 6. This allows the clamping device 10 to be supported on the first side wall 6 at four points, namely with the support surfaces 57a, 57b and the eccentric surfaces 22a, 22b. The pressure piece 50 presses the second eccentric element 30 with its eccentric surfaces 32a, 32b against the pressure plate 11 via its bearing surfaces 54.The glass plate 2 is thereby clamped between the clamping device 10 and the first support 41.

[0069] To reduce the risk of accidental release of the clamp, the shaft 21 of the first eccentric element 20 or the sections of the shaft 21 that rotatably mount the first eccentric element 20 on the pressure piece 50 have structured surfaces 23a, 23b that interact with the bearing surfaces 53a, 53b, which form a counterstructure or complementary structure to the structured surfaces 23a, 23b. The structured surfaces can increase the friction between the shaft 21 and the bearing surfaces 53a, 53b. Ideally, the structures of the bearing surfaces 53a, 53b, 23a, 23b interlock with each other. The positive locking is configured such that a rotation of the first eccentric element 20 about the first rotation axis 27 with respect to the pressure piece 50 is possible with an increased torque, whereby the positive locking is released.The first eccentric element 20 and the second eccentric element 30 each have a driving profile 24 on at least one of their end faces, in particular on the upper end face, optionally on both of their end faces, to which a tool (not shown) can be coupled, whereby a torque can be transmitted from the tool to the first eccentric element 20 or the second eccentric element 30. In the example shown, the driving profile 24, 34 is designed as an internal hexagon profile. The corresponding tool has an external hexagon profile. However, other driving profiles are also possible.

[0070] The pressure plate 11 has plate-shaped tabs 15 at its upper and lower ends, which protrude from the side of the pressure plate 11 facing the pressure piece 50. The tabs 15 serve, on the one hand, to stabilize the pressure plate 11 and, on the other hand, to enclose at least the second eccentric element 30 therebetween. To ensure accessibility to the drive profile 34, one or both tabs 15 have a passage 16 in correspondence with the drive profile 34. The tool can be inserted through the passage 16 into the drive profile 34. As shown, for example, in Figure 2 As can be seen, the driving profile 24 of the first eccentric element is arranged outside the tabs 15, so that in this example no second opening in the tab 15 needs to be provided for the driving profile 24.

[0071] Preferably, the first eccentric element 20 is held captively on the bearing surfaces 53a, 53b of the pressure piece 50. This can be made possible, for example, by the bearing surface 53a encompassing the shaft 21 by slightly more than half the circumference, whereby the shaft 21 can be locked into the pressure piece 50. Alternatively, the pressure piece 50 can, as in Figures 2 , 3 and 7 shown, form projections 56 into which a loop, for example of a rubber ring (not shown), can be hooked. The rubber ring can form a loop with its other side, which is placed around the first lever arm 51 or the second lever arm 52, spans the shaft 21 on the side not encompassed by the bearing surface 53a, 53b, and forms a loop with the other end, which is hooked into the projection 56.

[0072] In the embodiments shown, the first axis of rotation 27 and the second axis of rotation 37 run parallel to each other, regardless of the respective rotational position of the first and second eccentric elements 20, 30.

[0073] After the clamping device 10 has been inserted into the first slot between the glass plate 2 and the first side wall 6, the first eccentric element 20 is rotated using a tool, such as a torque wrench, until a first torque is reached. For visual control of how far the first eccentric element 20 has been rotated, the first eccentric element 20 has a marking 25 on at least one of its end faces. To establish the clamp, the first eccentric element 20 is rotated by an angular amount that does not exceed 180°.

[0074] When the first torque is reached, the second eccentric element 30 is rotated from a neutral position, in particular by an angular amount in one of two directions of rotation, which is less than or equal to 90° (e.g., first embodiment) or less than or equal to 45° (e.g., second embodiment). Depending on the direction of rotation, the pressure plate 11 is tilted about a tilt axis arranged transversely to the second axis of rotation 37, whereby the glass plate 2 is aligned vertically. If the second eccentric element 30 is rotated in one of its two directions of rotation, the glass plate 2 is tilted in one of its two directions of rotation ( Figure 13a ). If the second eccentric element 30 is rotated in the other of its two directions of rotation, the glass plate 2 is tilted in the other of its two tilting directions ( Figure 13b ). This allows the glass plate 2 to be vertically aligned by the fitter through a skillful selection of a rotational position of the second eccentric element 30 ( Figure 13c), despite, for example, curvatures in the glass plate or manufacturing and assembly tolerances.

[0075] The second eccentric element 30 has a marking 35 on at least one of its end faces, from which the rotational position of the second eccentric element 30 can be visually checked. The tab 15 can additionally have markings, such as arrows 15a, 15b, which indicate to the installer in which direction the pressure plate 11 or the glass plate 2 is tilted to align the glass plate 2 when the second eccentric element 30 is rotated about the second axis of rotation 37. It is preferred that the second eccentric element 30 is rotated from its neutral position, in which the pressure plate 11 is approximately parallel to the second axis of rotation, by an angular amount less than or equal to 90° or less than or equal to 45° in one of the two directions of rotation to align the glass plate 2.

[0076] When the glass plate 2 is aligned, the first eccentric element 20 is rotated until a second torque is reached which is greater than the first torque with which the first eccentric element 20 was initially rotated.

[0077] A particular advantage of the system described herein is that, for the alignment and clamping of the glass plate 2, only one access to the plate holder 3 is required from one side of the glass plate 2 to adjust the first and second eccentric elements 20, 30. This side can thus be mounted on the balcony side, eliminating the need to erect scaffolding on the outside for the installation of the glass plate 2.

[0078] After installation, the top of the balcony-side slot is closed using cover 5. List of reference symbols
