DESCRIPTION

Shower screen, in particular, shower screen

The invention relates to a screen, in particular with a shower screen, according to the characteristics specified in the heading of claim 1.

From document DE 296 23 000 U1 such a screen with a joint or hinge is known, in which a lifting mechanism with a support element and a pressure element is integrated. A cover is provided that at least partially surrounds the lifting mechanism, which is formed by hinge bodies of two hinge parts designed as hinge flaps, wherein the hinge bodies and therefore the hinge parts are coupled by middle of a hinge bolt. The hinge parts on one side are fixed or can be fixed to a door panel and on the other hand to a wall panel, where the door panel can pivot around a pivot axis that is defined by means of the hinge and that is essentially vertical. When the door panel is rotated and raised together with a part of the hinge, a gap is formed between its hinge body and the other hinge body connected to the wall panel, whereby an intermediate piece of the hinge is discovered. lifting mechanism provided with bevel. In the first position, where the passage of the screen is blocked by means of the door panel, there is also a gap between said hinge bodies. Therefore, foreign mechanical bodies, such as soap remnants or tartar deposits, which can negatively affect functionality even after a long period of use, can settle here. The lifting mechanism is partially visible and accessible from the outside, where also due to the germs or pathogens that enter, the hygiene requirements are not met in the necessary way.

In addition, from document DE 20 2006 012 415 U1 a hinge and a shower cubicle are known as well as a wall bracket, and in addition from document DE 94 20 398 U1 a assembly is known to hold a door leaf. Here, the housings of the lifting mechanisms are also formed by hinge bodies of the respective hinge parts, where when the door panel is pivoted, a gap emerges, and the lifting mechanisms become partially visible and accessible. The design of the covers as separate covers is also not suggested by these embodiments nor is it suggested by those skilled in the art.

In addition, from document EP 1 460 220 A2 a screen designed as a shower screen with a pivoting door panel is known, which is coupled to a fixed wall panel by means of at least one hinge. The hinge includes a first part of the hinge connected to the door panel, and a second part of the hinge connected to the fixed wall panel, where a hinge bolt is provided to couple the two parts of the hinge. In a first position or closed position the passage is closed by means of the door panel, for example from the outside towards the interior space of the shower or vice versa. By at least partially pivoting the door panel to a second position, the passage is at least partially released. In the closed position, the lower edge of the door panel is sealed by means of a sealing element towards the bottom or towards the edge of the bathtub. Due to the pivoting of the door panel, problems related to possible wear of the sealing element may occur.

Therefore, for example from document EP 1 243 213 A2 a shower screen is known whose door panel has a joint profile in the region of a vertical longitudinal edge. At the upper end of the joint profile, an upper bearing assembly with a longitudinal arcuate bearing arm is provided. In addition, a lower bearing assembly is provided below the lower edge of the door panel, which is coupled to said joint profile by means of a bushing. The lower bearing assembly comprises a support element arranged on the edge of the bath or the bottom, with a cavity in which a bushing connected to the joint profile can be fitted by means of cams, to determine the pivot positions, for example the first position and / or the second position mentioned above. The door panel is raised or lowered during pivoting according to the position of its rotational angle. It is possible to easily access said lower bearing assembly, and therefore there is a risk of malfunction due to dirt or foreign bodies entering the bearing assembly. In addition, the center of gravity of the door panel towards said lower bearing assembly comprises a fairly large distance or lever arm, so that considerable torque is produced on the bearing assembly and its cavities as well as on the cams, by which is limited to the massive and large-scale design of the bearing assembly.

In addition document DE 201 12 682 U1 discloses a hinge for a hinged door, in particular of a shower cabin, wherein the hinge has a first support part for fixing the hinge, a second support part for attachment to the hinged door, and an intermediate piece. The intermediate piece is provided with a sliding support surface inclined towards the pivot axis of the hinge, so that an axial movement can be superimposed on the pivoting movement. The intermediate piece is arranged in a support section preferably in the form of a sleeve or cylindrical of said first support part. The bolt also fits into a sleeve-shaped or cylindrical support section of the second support part, wherein this support section comprises an annular shoulder with a sliding support surface. The annular shoulder with the sliding support surface projects towards the

support section of the first support part, wherein said sliding support surface rests on the inclined sliding support surface of the intermediate piece. Said support sections are located outside the planes of the hinged door and the fixed wall panel and also of the pivot axis of the hinge, so that the hinged door can only be opened by turning from the closed position in a address. Neither the hinged door nor the wall panel contain cavities in the region of their associated vertical longitudinal edges. Because the intermediate piece with the inclined sliding support surface and also the associated sliding support surface of the second part of the hinge are disposed within the sleeve-shaped or cylindrical support section of the first support part, the Sliding bearing surfaces comprise a fairly small radial width, whereby large surface pressures that are not negligible can occur.

From this, the invention aims to develop said screen with little construction effort so that with a simple design and a small construction volume, by pivoting the door panel can be raised or lowered. For this, the smallest possible number of components and with a low volume of construction must be required to reduce manufacturing and assembly costs. In addition, the disadvantages mentioned above should be avoided. Also, the use of materials should be minimized, and also the design requirements that are important in particular for shower screens must be met in a simple manner.

The solution for this purpose is met according to the characteristics specified in claim 1.

The proposed screen is characterized by the integration of the lifting mechanism in the hinge and the lid formed separately that at least partially surrounds the lifting mechanism through a simple and at the same time functional construction. The lifting mechanism, which produces an elevation when the door panel is pivoted from the first position or closed position and which allows a descent when pivoted back, is disposed inside the lid also integrated in the hinge and therefore is Protected against external influences. The door panel includes a cavity in the hinge region on its vertical longitudinal edge, in which the lifting mechanism and the cover advantageously provided are arranged and / or at least partially integrated. The lid is hollow inside and surrounds the hinge bolt and the elements of the lifting mechanism, and is preferably designed in an essentially cylindrical shape. The one part of the hinge, to which the door panel is fixed, for example, also includes a cavity that corresponds to the door panel cavity, where the cover provided according to the invention also partially fits into the cavity of said part of the hinge. The cover includes a groove that extends in essentially vertical direction, through which a hinge arm of the second part of the hinge passes, where the cover is fixed against rotation with respect to the second part of the hinge and / or to the wall panel attached to it. The lid has a certain height in the vertical direction, which is at least about the same size as the height of the cavity or the cavities of the door panel and the first part of the hinge, whereby a fixation is achieved in the axial direction. By means of the pivoting movements and the axial movements of the door panel that are achieved, consequently the lid is raised or lowered. The cover comprises a cover at its upper end, whereby the entry of water droplets or dirt from the top inwards and towards the lifting mechanism provided therein is advantageously prevented.

The door panel is preferably designed as a retractable door, which can be opened by turning from the closed position in both directions, functionally in angular ranges of 90 ° and higher. If the wall panel is designed, similarly to the door panel, preferably as a plate, in particular a frameless glass plate, and / or as a fixed partition element of the screen, alternatively said cavity can be arranged in the region of the vertical longitudinal edge of the wall panel. If the fixed wall panel is formed by a room wall, in particular a bathroom or shower room, then said cavity as well as the first part of the hinge is associated with the pivoting door panel and the second part of the hinge is conveniently designed as an angular piece that can be connected to the room wall, whose hinge arm is integrated together with the lifting mechanism in the associated cavity of the door panel.

For the coupling of the first part of the hinge, which is connected to the door panel, a hinge bolt is provided with the second part of the hinge which is arranged in the region of said cavity. The lifting mechanism comprises two lifting bodies and / or supporting elements and pressure elements that correspond to each other, which are connected in a rotationally fixed way directly or indirectly with the first hinge arm or the second hinge arm. Said lifting bodies or elements have inclined surfaces, curved parts or the like associated with each other that are arranged against each other, so that when the door panel is pivoted, it is raised or lowered.

The screen preferably includes two hinges arranged separated from each other with the integrated lifting mechanism and the surrounding cover. Therefore, the forces are distributed over both lifting mechanisms, so that they can be interpreted as an individual lifting mechanism for significantly lower loads, and as a result they can have a significantly reduced construction volume. In addition, the two hinges are advantageously arranged at predetermined intervals below the upper edge of the door panel or above the lower edge of the door panel. It has been proven that it is convenient to arrange

hinges at least 5% from the top edge or from the bottom edge, where the distance is determined as convenient by up to 30% from the top edge or the bottom edge.

In addition, the hinge including the lifting mechanism is preferably designed so that the door panel can be pivoted or tilted from the first position or closed position in both directions, and in each case 5 advantageously up to 90 °, in particular up to 100 °, and if necessary further, so that the door panel can be pivoted at a total angle of at least 180 °, advantageously 200 ° and if more of that is necessary. The door panel is designed as a folding door and therefore can be pivoted to two of said second positions to free the passage of the screen. By designing the screen as a shower screen, the door panel, if necessary, can turn inwards from the interior space of the shower or outwards to an external space. In the one or both second positions, the door panel can advantageously be locked, in particular by an appropriate design and coordination of the lifting and pressure elements, which include cavities and corresponding cams on the inclined guide or contact surfaces, in particular to establish the closed position and the two second open positions. In addition, it should be noted that because the lid and in particular the arrangement of the lifting mechanism inside the lid, the lifting mechanism cannot be seen by an operator or user, whereby they are conveniently fulfilled the safety and / or design requirements of the screen, and in particular its hinge. It has been proven as particularly convenient to design the cover in essentially and / or at least approximately cylindrical shape, whereby not only an attractive design is possible, but also a compact construction form is achieved. Particular embodiments and further developmental forms of the invention are provided in the dependent claims as well as in the additional description.

The invention will be explained in more detail in reference to the exemplary embodiments shown in the figures, without being limited thereto. It shows:

Figure 1 a perspective representation of the screen in the hinge region,

Figure 2 a side view of the hinge in the raised position of the first part of the hinge,

25 Figure 3 a detailed representation similar to that of Figure 1, but without a cover,

Figure 4 a detailed representation similar to that of Figure 1 of a particular embodiment.

Figure 1 shows in detail the screen with a pivoting door panel 2 and a fixed wall panel 4, with respect to which the door panel 2 is arranged or pivotably mounted around a pivot axis

essentially vertical 6 by means of a hinge 8. The screen preferably includes two of said hinges 8,

30 which are each arranged at a predetermined distance above the lower edge of the door panel 2 or below the upper edge of the door panel 2. Conveniently, the two hinges are designed accordingly and the following explanations are Refer to each of these hinges. The hinge 8 includes a first part of the hinge 10 and a second part of the hinge 12, which are coupled together to establish the pivot axis 6 by means of a hinge bolt, which is inside a cover 14. The pivot axis 6 is located in the region of the vertical longitudinal edge of the door panel 2 in its vertical plane and therefore the door panel 2 can pivot as a folding door from the closed position represented in Both directions

The first part of the hinge 10 is fixed to the visible exterior of the door panel 2 in a suitable manner, preferably by means of a connection element 16 arranged on the rear side of the plane of the representation and on the rear side of the door panel 2 , wherein the door panel 2 is fixed between the first part of the hinge 10 and the element of

40 connection 16. The connection element 16 is, according to the figure, the same as the first part of the hinge 10,

designed in a flat manner, where the first part of the hinge 10 is joined by means of suitable fixing elements, such as screws or the like, with the connection element 16. Also, the connection element 16 can be designed in principle as a screw, whose screw head is disposed at the level of the rear side of the door panel 2, and through corresponding recesses of the door panel 2, preferably in combination with conical intermediate pieces 45, is connected to the first part of the hinge 10 In addition, the hinge portions 10, 12 may comprise contours or other configurations of the surface or of the cutting bodies corresponding to the desired design, which deviate from the rectangular shape shown here.

In correspondence with the first part of the hinge 10 the second part of the hinge 12 is connected with the fixed wall panel 4, in particular with an additional connecting element 18 to its rear side. For the element of

50 additional connection 18 and its coupling with the second part of the hinge 12 are applied analogously

explanations given for the first connection element 16. In addition, the second part of the hinge 12 can be arranged and / or designed correspondingly to the first part of the hinge 10. The second part of the hinge 12 includes a hinge arm 20 which is integrated in a conveniently rectangular cavity 21 of the first part of the hinge 10 and a cavity 22 of the door panel 2, where the end not visible here of the hinge arm 20 55 is covered by the cover 14. The cover is designed as a lid 14 that is open at one end,

preferably at the lower end. The hinge bolt defining the pivot shaft 6 fits on one side at said end of the hinge arm 20 and on the other hand on the support elements 24, 25 of the second part of the hinge 12 correspondingly arranged. In the embodiment shown here, the support elements 24, 25 are designed as legs of the first part of the hinge 10 aligned to the second part of the hinge 12, or included therein or joined therewith. The mentioned support elements or legs 24, 25 define the lower and upper part of the cavity 21 of the first part of the hinge 10. The support elements 24, 25 are provided in the vertical direction or in the direction of the pivot axis 6 at a predetermined distance 26, and the cavity 21 of the hinge portion 10 comprises a height 26 corresponding to this distance. As shown, the height of the cavity 22 of the door panel 2 is conveniently larger than the predetermined height 26, in particular to compensate for dimensional tolerances and / or to facilitate assembly and / or to define the orientation of the panel of door 2 with respect to the hinges 8 or the hinge part 10.

In the coupling region of the two hinge parts 10, 12 and / or in the region of the pivot shaft 6 there is a lifting mechanism, which is advantageously at least partially surrounded by the cover 14 and is protected against it by external effects The cover 14 preferably has, at least through the turning range of the door panel 2, an essentially cylindrical and / or coaxial outer surface 27 with the hinge shaft 6, so that a fixing of this can easily be provided sealing element 28 with the second part of the hinge 12, so that at least in the first position of the door panel 2 a seal is provided in the region of the cavity 22 in combination with the cover 14.

At the upper end, the cover 14 comprises a cover 29 that includes an opening in the central area, not shown, through which the hinge bolt passes. In addition to this opening, which preferably surrounds the hinge bolt with an annular gap of near zero thickness, the components inside the lid 14 are therefore reliably protected against the entry of water droplets, dirt , tartar deposits or the like. The cover 14 includes a slot 30 advantageously open on the lower side, through which the hinge arm 20 is projected into the internal space of the cover 14. The cover 14 is fixed against its rotation by means of the hinge arm 20, with respect to the second part of the hinge 12 or the wall panel 4. Because the groove 30 is designed to be open towards the lower end of the lid 14, when the lid 14 is pivoted, the movement in the axial direction and thus the lifting of the door panel 2 is achieved. The cover 14 has a height 31 in the axial direction that is preferably at least about the same size as the height 26 of the cavity 21. When the door is pivoted Door panel 2 therefore rises the cover 14 in the axial direction upwards and correspondingly lowers when the door panel 2 is closed together with it. Therefore, unwanted gaps between the door panel 2 and the cover 14 are advantageously avoided and in particular the entry of foreign bodies or dirt into the hinge region is prevented. As can be seen, the upper edge 32 of the hinge arm 20 comprises a distance 34 towards the lower edge 33 of the lower support member 25 in the closed position. According to this distance 34 the cover 14 is placed directly above the groove 30 and / or is provided with a flat part 36. Thanks to the flat part 36 and in particular in combination with the cover 29, the cover 14 has a stable and reliable construction. Because on the other hand the groove 30 is designed to be open towards the lower side, the lid 14 can be easily mounted during manufacturing.

The hinge 8 is preferably designed and arranged such that the pivot shaft 6 is located in an essentially vertical plane that extends through the door panel 2. Here, the door panel 2 includes in the region of the vertical edge that it is opposite the second part of the hinge 12, the cavity 22, which is preferably designed to be open in the direction of the second part of the hinge 12. In this cavity 22 the lid 14 and / or at least partially integrated therein or the lifting mechanism disposed therein and / or the coupling elements of the two hinge parts. If the connection element 16, as depicted, is similarly configured in the form of a plate corresponding to the first part of the hinge 10 configured in the form of a plate, the connection element 16 then also includes a cavity and which is preferably analogous to the cavity 21 of the hinge part 10. In said embodiment, the cover 14 is at least partially also arranged in the aforementioned cavity of the connecting element 16 and / or integrated in this cavity. Furthermore, between the mutually opposite vertical end edges of the door panel 2 and the wall panel 4 there is a continuous seal strip 35, which is located in the hinge region advantageously according to the figure behind the hinge arm 20, so that at least in the first position or closed position, where the passage of the screen is closed by means of the door panel 2, an operationally reliable design is provided.

The lifting mechanism provided inside the cover 14 includes as a lifting body a support element connected to the first part of the hinge 10 in a rotationally fixed manner and also a pressure element connected to the second part of the hinge 12 in rotationally fixed shape, on which the support element rests. The lifting body or the support element and the pressure element comprise mutually corresponding support surfaces, such that when the door panel 2 is pivoted about the pivot axis 6 at a predetermined distance in the direction of the arrow 38 starting from the first position represented here, it moves up.

The hinge 8 is advantageously designed integrated and / or connected to the screen, so that the door panel 2 can be pivoted at a predetermined angle as a folding door either outwards, or according to the figure from the plane of the representation towards the front, as well as towards the interior, for example towards an interior space of the shower, that is according to the figure backwards of the plane of the representation, where in each case due to the integrated lifting mechanism occurs an elevation of the door panel 2. The predetermined angular range can reach an outward as well as inward value that is conveniently at least about 90 °, conveniently at least 100 °, so that the full pivoting angle is of at least 180 °, conveniently up to 200 ° and if more of that is necessary.

In an alternative embodiment of the screen and / or the hinges the wall panel is formed by a fixed wall of the room, for example a bathroom or shower room, where the second part of the hinge is designed with the hinge arm 20 as an angular piece. Here, the door panel 2 is in the first position essentially perpendicular to the wall of the room. In addition, the second part of the hinge can be connected with a compensation profile and / or wall profile, which is connected in a suitable way for example with a fixed wall of the room.

Figure 2 shows in a side view the hinge 8 without the screen, where the first part of the hinge 10 is rotated, with respect to the second part of the hinge 12 and around the pivot axis 6, in a angle of approximately 30 ° in the direction of arrow 40 from the first position. Here, according to the design of the lifting mechanism, the first part of the hinge 10 and therefore the door panel is raised with an elevation 42 of for example 4 mm with respect to the second wall panel or the second part of the hinge 12. As can be seen, the first part of the hinge 10 and the lid 14 disposed in its cavity 22 are raised, where due to the groove 30 of the lid 14, it can be moved upwards with respect to the arm hinge 20. The seal strip 35 advantageously fixed to the wall panel in a suitable way, for example by clamping, extends according to the figure back of the hinge arm 20 and generally continuously essentially above the total height of the wall panel or screen.

Figure 3 shows, similar to Figure 1, a particular embodiment where the cover is not shown. The lifting mechanism can now be seen with the support element 44 of the first part of the hinge 10 and in addition the pressure element 46 of the second part of the hinge 12. The support element 44 is designed as a first profile of cam and the pressure element 46 as a second cam profile, wherein both cam profiles comprise surfaces that are coincident and contiguous. In the first position shown, a cam 48 of the upper support element or of the upper cam profile 44 is projected to a corresponding groove 50 of the pressure element or of the second cam profile 46. The cam 48 and the groove 50 have lateral surfaces and / or correspondingly designed sliding surfaces, so that when the door panel 2 is pivoted around the pivot axis, the door panel 2 is raised axially. The support element 44 and the pressure element 46 are advantageously designed as discs that surround the pivot axis 6 defined by the hinge bolt 52. In the lower region of the cavity 21 in the first part of the hinge 10 is arranged advantageously at least one, conveniently two, guide bodies 54 below the support element 44 as well as the pressure element 46 contained in the lifting mechanism. Also, the one or more guide bodies 54 are advantageously arranged coaxially to the hinge bolt 52 and / or thereon.

Figure 4 shows in a three-dimensional representation, the screen or hinge 8 with the first cam profile 44 and the second cam profile 46 arranged below the first. Moreover, the hinge bolt 52 can be easily seen, which is supported and / or mounted on the support elements 24 and 26 of the first part of the hinge 10. Also, the two guide bodies 54 can be seen well, 55, which are similarly designed as discs and which, as well as the support elements 44, 46, are penetrated by the hinge bolt 52. The first guide body 54 is rotatably fixedly coupled with the first part of the hinge 10 , while the second guide body 55 engages in a rotationally fixed manner with the second part of the hinge 12. The two guide bodies 54, 55 have mutually associated and contiguous inclined surfaces, so that when the door panel 2 is pivoted, This rises conveniently. By means of the fixing elements 56, 58, which are preferably designed as screws and corresponding threaded heads, the two hinge parts 10, 12 that are associated are interconnected and behind the door panel 2 or the wall panel 4, and the fixed connection elements 16 or 18.
