Description
[0001] Clamping device for windows and / or doors
[0002] The invention relates to a clamping device for windows and / or doors according to the preamble of claim 1.
[0003] Such a clamping device is already known from EP 2 751 361 B1, which is also referred to as a door or window stop. This clamping device is used to hold or lock windows or doors and prevents a door or window from slamming shut, swinging open, or moving in any other undesirable manner. For this purpose, the clamping device is clamped between a pivoting window and its frame, a windowsill, or another abutment. When used on a door, the clamping device is preferably clamped between the door leaf and the floor or another abutment.
[0004] Particularly when such a clamping device rests on the floor, it is not always easy to place the clamping device firmly under a door leaf. The invention is therefore based on the object of providing a clamping device that, while being robustly constructed, not only exhibits good clamping properties but can also be moved into its operating position as smoothly as possible.
[0005] This object is achieved according to the features specified in claim 1.
[0006] According to the invention, it was first recognized that a clamping device cannot always be inserted between a floor and a door leaf without problems and with as little effort as possible. This is due to the fact that complex sliding and adhesion conditions can exist both between the top side of the clamping device and the door leaf and between the bottom side of the clamping device and the floor, which can influence each other in an undesirable way. It was also recognized that a pivoting door can even move a clamping device in an undesirable way, so that no clamping effect can develop. Against this background, it was also recognized that it must be possible to insert a clamping device safely under a door leaf with little effort, for example with a foot that is not protected by a shoe.The aforementioned technical problems are solved by a laterally outward bevel of an adhesive-friction soft sliding surface. Because the soft sliding surface is chamfered or beveled in such a way that it slopes laterally outwards, a door leaf swinging sideways towards the base body can easily slide onto it and then slide back down again. The sliding of the door leaf is also facilitated by a ribbed structure on the underside. The underside faces the floor and rests suitably on it. The ribbed structure, like the ramp-like bevel, means that the clamping element can be pushed under a door leaf with little effort, but once pushed under, it exerts a high clamping force.In contrast to the clamping device known from EP 2 751 361 B1, a soft sliding surface is not only inclined in the direction of ascent or descent of a large-dimensioned wedge, but also substantially or approximately transversely to these directions, namely at least towards the outer side surfaces.
[0007] The soft sliding surface could be aligned with the hard sliding track. Since the hard sliding track adheres less strongly to a door than the soft sliding surface, the door can easily slide along the hard sliding track. While simultaneously sliding toward the wedge-like rise of the base body, the door can easily exert force from above on the base body, pressing it against the floor, at least in some areas. Alternatively, or additionally, the soft sliding surface could form a ramp sloping outward laterally on the outer side surfaces.
[0008] This allows the door to slide more easily over the adhesive soft sliding surface without dragging the base body along with it due to excessive friction on the door.
[0009] The soft sliding surface could surround the hard sliding track and form a ramp sloping outward laterally with varying angles of inclination along the circumference. This allows a door to slide onto or off the base body relatively easily from all sides.
[0010] The soft sliding surface could slope or be inclined at at least one angle selected from the range of 1° to 15°, with the angle of inclination spanned by the soft sliding surface and a plane in which the entire hard sliding track or at least a section of the hard sliding track lies. This angle range has proven particularly advantageous, on the one hand, to still create sufficient clamping effect between the soft sliding surface and a door, and on the other hand, to enable the door to slide smoothly onto the base body.
[0011] The ribbed structure could have consecutive ribs.
[0012] Ribs reduce the effective static friction area between the floor and the base body in a specific contact situation. Alternatively or additionally, the ribs could be wedge-shaped in cross-section. A wedge has only a very small contact line, edge, or possibly a bead-like surface at one end, so the effective static friction area between the floor and the base body can be reduced or increased depending on the force acting from above on the base body and pressing it against the floor.
[0013] Against this background, a rib could have an inclined beveled surface that extends from the base of the underside to a contact edge or a possibly flat or curved contact bulge that protrudes from the base. The beveled surface can exert adhesion with a greater or lesser proportion of its surface, depending entirely on the contact force with which the base body is pressed against the floor. The beveled surface preferably rests first on the floor at its end facing the branches or the high area, namely at the contact edge, when pressed against the floor.
[0014] The beveled surface could be inclined at a bevel angle against the ground or a support surface for the base body, such as a floor, with the bevel angle selected from the range 0.5° to 5°. This bevel angle range is particularly suitable for use on both tiles and carpets.
[0015] The beveled surface could have a length selected from the range of 2 to 4 mm. Alternatively or additionally, the support edge or bead could be raised from the ground with a height in the range of 0.05 to 0.5 mm. This height range is particularly suitable for use on both tiles and carpets.
[0016] The core element could have laterally outward-facing outer surfaces extending between the bottom and top sides, with the enveloping element following and covering the outer surfaces of the core element. This allows for the creation of a particularly stable, completely enclosed base body.
[0017] The core element could have a tongue-like free end on the flat area, which has at least one tooth or pin protruding from its surface, which is received by the enveloping element and / or overmolded and / or enclosed by it. Several teeth or pins or other structures could also be provided which enter into a positive connection, frictional connection and / or material connection with the enveloping element. This ensures that a free tongue of the enveloping element no longer easily detaches or peels off from the core element, even in the event of severe bending. In particular, when the base body is pressed against a window or its frame, an elastomer can detach from the core element in prior art clamping devices. The teeth and / or pins prevent the enveloping element from detaching, even in the event of very severe bending.
[0018] The sheathing element could extend 1 to 2 cm beyond the outer edge of the free end of the core element, thereby forming a flexibly deformable free end of the sheathing element. Such a long free end or such a long free tongue made of elastomer can be bent with little effort.
[0019] The enveloping element could form three free ends of the base body. This creates a wedge-shaped clamping device, each of which can be inserted into door gaps, window gaps, or other narrow spaces. Alternatively or additionally, the core element could form a shape with three free ends, which is inscribed in the enveloping element with its free ends. This stabilizes the enveloping element against torsion and twisting. Two essentially laterally outwardly curved branches could be provided, each tapering to a point in width towards a first and second free end and simultaneously increasing in height, wherein a tongue is provided which, starting from the flat region at the third free end, increases in height towards the branches, and wherein the two branches and the tongue merge continuously into one another in a central region.This creates a basic body that is designed as a large wedge, but which also has three free ends, each of which also forms a smaller wedge.
[0020] The core element could follow the hull element in its tapered and raised configuration. This would stabilize the hull element against torsion and twisting across its entire length.
[0021] The sheathing element could be softer than the core element. This would allow the sheathing element to adhere more strongly to doors or windows than the core element. Alternatively or additionally, the sheathing element could be made of an elastomer with a Shore A hardness in the range of 50 to 80, and the core element could be made of polypropylene. This would make the core element sufficiently hard yet flexible, while the elastomer, a thermoplastic elastomer, sufficiently soft and adhesive.

[0037] Fig. 1 shows a clamping device for windows and / or doors, comprising a wedge-like base body 1 with a bottom side 2, a top side 3, a core element 4 and a covering element 5, wherein the heights 1 a of two side outer surfaces 6a, 6'a of the base body 1 increase from a flat area 1 b in the direction A of a high area 1 c such that the base body 1 forms a wedge or a wedge-like structure.
[0038] The core element 4 forms a self-contained, circumferential, serrated hard sliding track 4a on the upper side 3. The shell element 5 forms a soft sliding surface 5a on the upper side 3. The soft sliding surface 5a is chamfered or beveled in such a way that it slopes laterally outward toward the outer side surfaces 6a, 6a'. This is particularly clearly shown in Fig. 5a.
[0039] Fig. 2 shows a top view of the upper surface 3, the soft sliding surface 5a, and the hard sliding track 4a. The upper surface 3 is smooth and has no ribbing.
[0040] Fig. 3 shows that the covering element 5 has a corrugated structure 8 on the underside 2 of the base body 1.
[0041] Fig. 4 shows, in a top view of the underside 2, that the corrugated structure 8 has successive ribs 9 that are oriented essentially parallel to each other. The ribs 9 extend over the entire underside 2. The upper side 3, on the other hand, is completely smooth and has no corrugations.
[0042] Fig. 5 shows that the soft sliding surface 5a is aligned with the hard sliding track 4a and forms a ramp that slopes laterally outward on the outer side surfaces 6a. Figs. 1 and 2 show that the soft sliding surface 5a circumferentially surrounds the hard sliding track 4a and forms a ramp that slopes laterally outward with different angles of inclination 7 along the circumference.
[0043] Figs. 5 and 11 show, in a sectional drawing based on an angle of inclination 7, that the soft sliding surface 5a slopes or is inclined at an angle of inclination 7 selected from the range 1° to 15°, wherein the angle of inclination 7 is spanned by the soft sliding surface 5a and a plane E in which the hard sliding track 4a lies. Fig. 5a shows in detail the outward inclination of the soft sliding surface 5a on two sides of the base body 1.
[0044] It is specifically shown in Figs. 5 and 11 that a section of the hard sliding track 4a, from which the soft sliding surface 5a slopes laterally outward on two sides, lies in plane E. Figs. 5 and 11 show that the soft sliding surface 5a slopes laterally outward on two sides. This is indicated by two dashed arrows in Fig. 5.
[0045] Fig. 7 shows, in a side view and using an enlarged detail, that the corrugated structure 8 of the underside 2 has wedge-shaped ribs 9 in cross-section. The detail is shown in a dashed ellipse. Several ribs 9 are arranged one behind the other, resembling a sawblade in cross-section.
[0046] Fig. 7 specifically shows that a rib 9 has an inclined bevel 10, which, starting from a base 2a of the underside 2, ends at a support edge 11 that protrudes from the base 2a. In the use position of the clamping device, the support edge 11 rests on the floor. The bevel 10 is inclined at a bevel angle 12 against the base 2a, wherein the bevel angle 12 is selected from the range 0.5° to 5°. The bevel 10 has a length selected from the range 2 to 4 mm. The support edge 11 protrudes from the base 2a with a height in the range 0.05 - 0.5 mm.
[0047] Fig. 1 shows that the core element 4 has laterally outwardly oriented outer surfaces 6 extending between the bottom side 2 and the top side 3, with the sheathing element 5 following the outer surfaces 6 of the core element 4 and completely covering them laterally outward. The core element 4 is provided with a cavity within its interior, the inner wall of which is not covered by the sheathing element 5.
[0048] Fig. 3, in conjunction with Fig. 10, shows that the core element 4 has a tongue-like free end 13 on the flat region 1b, which has at least one tooth 14 protruding from its surface, which is received by the enveloping element 5 and overmolded by it. Specifically, three larger teeth and four smaller teeth 14 are provided, arranged in rows one behind the other. The enveloping element 5 forms three viewing windows 5b, through which the three larger teeth 14 are visible in a plan view of the underside 2.
[0049] Fig. 10 also shows that the sheath element 5 projects one to two cm beyond the outer edge of the free end 13 of the core element 4 and thereby forms a flexibly deformable free end 15 of the sheath element 5.
[0050] Fig. 1 shows that the enveloping element 5 forms three free ends 15, 16, 17 of the base body 1, and that the core element 4 forms a figure with three free ends 13, 13a, 13b, which is inscribed in the enveloping element 5 with its free ends 15, 16, 17. The core element 4 is hollow, with the cavity also being a figure inscribed in the core element 4.
[0051] The base body 1 has two branches 18, 19 of different lengths, essentially curved outwards, which taper in width toward a first and second free end 16, 17 and simultaneously increase in height. The two branches 18, 19 are arranged in a V-shape, and their tips diverge from each other and curve outwards.
[0052] The base body 1 has a tongue 20 which, starting from the flat region 1 b at the third free end 15, increases in height in a wedge shape in the direction of the branches 18, 19, wherein the two branches 18, 19 and the tongue 20 continuously merge into one another in a central region 21.
[0053] The branches 18, 19 are neither of equal length nor of equal height at their tips. The outer lateral surfaces 6a, 6'a are also not of equal height and rise to varying degrees from the flat area 1b to the high area 1c. The core element 4 follows the enveloping element 5 in its tapering and elevating pattern, replicating this within its body.
[0054] The shell element 5 is softer than the core element 4. The shell element 5 is made of a thermoplastic elastomer with a Shore A hardness in the range 50 to 80 and the core element 4 is made of polypropylene.
[0055] Figures 12 and 13 show the use of a clamping device 1 on a window 22.
[0056] In Fig. 12, the tongue 20 is pressed against the window 22 from below, while the branches rest on a windowsill. The tongue 20 can be easily bent to a very high degree without the elastomer detaching from the core element 4. In Fig. 13, the tongue 20 is pressed against the window frame in a hinge area, while the branches rest on the window 22. The tongue 20 can be easily bent to a very high degree without the elastomer detaching from the core element 4.
[0057] Fig. 14 shows the use of a clamping device 1 on a door 23 in different orientations when sliding between the door 23 and a floor 24 with a foot.
[0058] The clamping device described here can be easily and safely pushed under a door 23 with the foot, even without shoes. The door 23 can easily slide onto and off the clamping device.
