Description

The The invention relates to a swing door hinge for shower enclosures for articulating a fixed element with a swiveling door element, one fixed to the stationary element immovable hinge body, in the a hinge pin rotatable, but not displaceable in the axial direction is mounted, with one on the pivoting door element immovably fixable hinge counter plate by means of connecting means is firmly connected, has.

hinges and also hinged door hinges are in the most diverse embodiments known.

In the prior art shower enclosures are already explained with at least one swing door. In this regard, for example, reference is made to the German utility model DE 299 05 096 U1 ,

From the DE 200 10 009 U1 a hinge for glass or acrylic glass swing doors with two hinge parts is known, which are hingedly connected to each other around a pivot pin and each having a pivot pin surrounding the support ring, the support rings superimposed support surfaces having on one hand at least one notch and on the other hand at least one projection, the protrudes into the notch in a rotational position and is lifted out of the notch during rotation of the band parts.

The Swing door hinge according to the invention should find application in shower enclosures. To such shower enclosures counting also shower cubicles, ready-made showers and others suitable for showering Facilities, such as steam showers. The term shower enclosure is here representative of used all these different facilities.

It are also swing doors known after opening automatic in a zero position after opening back by a user move. However, these known swing doors are included the pivoting movement is raised or lowered.

at especially aesthetic Shower enclosures become the door elements Nowadays made of glass and therefore are correspondingly heavy. Should such a glass element used as a swing door for a shower enclosure If necessary, the swing door hinge must be strong enough form to absorb the forces occurring. In addition, one leads Vertical movement of such a door to sealing problems.

task Therefore, it is the object of the present invention to provide a swing door hinge for shower enclosures ready to put that after pivoting from a chosen position independently returns to this position and during the pivoting movement no translational movement in the axial direction performs.

Is solved this task by a swing door hinge according to the teaching of claim 1.

at the swing door hinge according to the invention the hinge pin is firmly connected to a sliding element. He can also be formed integrally with it be.

Of the hinge body the swing door hinge according to the invention is equipped with an abutment that has a curved surface, against which the sliding member abuts. In addition, slides the slider on the curved surface along when the hinged door element is pivoted, since the hinge pin with the hinge counter plate with the help of connecting means firmly connected and in the built-in Condition is therefore firmly connected. The hinged counter plate In turn, it is immovably fixed to the pivotable door element and is thus firmly attached when installed.

The The cam surface located in the abutment has at least one recess into which the sliding element can slide. This poses thus the chosen one Zero position.

The Abutment of the swing door hinge according to the invention rests on at least one spring, which is supported on or in the hinge body and a spring force in the axial direction of the hinge pin in the direction of exercises the abutment. The abutment is in the direction of the longitudinal axis of the hinge pin in terms of of the hinge body movable guided.

by virtue of the arrangement described is when pivoting the door element one with the swing door hinge according to the invention equipped Shower enclosure is not the door element as such in the longitudinal direction of the hinge pin moved up or down. Rather, that leads Abutment such a translational movement by, hereinafter hereafter even closer will be received.

Of the Hinge pins can in principle have any shape. Preferably However, this is a cylindrical hinge pin, since its storage is easier to realize.

To a further preferred embodiment the sliding element of the swing door hinge according to the invention is a substantially perpendicular to the longitudinal axis The hinge pin extending transverse pin is. In addition, the curved surface is a the hinge pin at least partially circumferential surface, in particular a circular ring surface.

The cam surface in the abutment is preferably configured wave-shaped and has preferably three depressions in the form of troughs which, when viewed in the direction of rotation, lie at -90 °, 0 ° and + 90 °. 0 ° indicates the zero position, at the door element the shower enclosure closes. + 90 ° the position at which the door element outward open is, during -90 ° the position referred to, in which the door element opened inside is and forms an angle of about 90 ° to the fixed element.

In the position of + 90 ° can be clean the inside of the hinged door element well, without that the door element tends to be self-acting in the 0 ° position to return. Dripping in the -90 ° position that on the hinged door element down-draining water in the interior of the shower enclosure, for example a shower tray. In this state, the pivoting shower element Dry well without causing pollution of the outside area the shower enclosure is to be feared.

The Wave crests are located in this embodiment in the section between + 90 ° and 0 ° as well between 0 ° and -90 °. Will therefore the hinged door element pivoted only a small degree of angularity from these three positions, then it returns automatically in the next lying angle position back. Of course this applies also for the 0 ° position.

The Abutment of the swing door hinge according to the invention preferably has a through hole through which the Hinge bolt extends. This hole has two sections with different diameter. The paragraph between these two Sections represents the curve surface represents.

It is possible, too, the curved surface to form in a separate element, which of the abutment is held. In this case, the position of the element equipped with the cam surface can in terms of of the abutment changed, z. B., so that it is possible, a fine adjustment the curved surface and thus reach the wave troughs described above.

Preferably the bore in the abutment has a cylindrical shape. The hole in the smaller diameter section has one Diameter, which is approximately the outer diameter corresponds to the cylindrical hinge pin. This way will the hinge pin in the bore area with the smaller diameter rotatably guided and stored.

Around the position of the movable door element with respect to To be able to finely adjust the stationary element is the hinge pin the swing door hinge according to the invention preferably in several positions on the hinge counter plate, which the hinged door element holds, firmly fixable.

The Swing door hinge according to the invention is in the context of the present documentation in connection with a fixed flat Element described. However, it is also possible, this swing door hinge to attach to a fixed element that is not designed flat. Thus, as a fixed element, for example, a wall of a Bath or a shower enclosure serve.

The Hinge counter plate preferably has an open elongated Recess on, in which the hinge pin by means of connecting means firmly can be fixed. This elongated Recess preferably represents approximately a half shell whose Cross-sectional shape of that of a Gleichdicks corresponds approximately. A match is characterized by the property that it is same when measuring the diameter from different angles or approximate has the same diameter values. Since two half-shells in about one Form full shell, corresponds to the same thickness cross-sectional shape of the elongated Recess only the cross-sectional shape of a half diked.

Of the Diameter of this Gleichdicks is preferably greater than the diameter of the hinge pin. In addition, the hinge pin with at least one transverse to its longitudinal axis extending through Slot provided, whose largest diameter extends approximately in the axial direction. The hinge pin can doing so with the help of a through the slot extending cap screw be fixed in place in the half shell. In addition, this is Design a fine adjustment of the position of the hinge pin in the recess and a fixation in the selected position possible.

To a further preferred embodiment the head screw cooperates with a cylinder sleeve through which this head screw extends and by means of the head screw the hinge pin fixed in the half shell.

The The invention will be described below with reference to an illustrated in the drawings, preferred embodiment a swing door hinge according to the invention explained in more detail.

From show the drawings:

1 an inventive swing door hinge with an assembled, attached to a solid sheet-like element hinge body and attached to a movable door element hinge counter plate, hinge body and hinge counter-body are not yet combined,

2 that in the 1 shown swing door hinge in an exploded view, wherein the hinge body is connected to the hinge counter plate, however,

3 a perspective view of the hinge body from above, wherein different parts of the abutment are omitted,

4 a perspective view of the hinge counter plate from above,

5 a side view of the in the 4 shown hinge counter plate,

6 a supervision of the in the 4 shown hinge counter plate from above,

7 a view from the outside - with respect to a shower enclosure - of the shown in the previous figures, assembled swing door hinge and

8th a view from the inside - based on the shower enclosure - in the 7 shown swing door hinge.

That in the 1 shown door hinge has a hinge body 3 that with a hinge counter plate 4 by means of a hinge pin 5 cooperates and for articulating a fixed flat, approximately rectangular element 1 with a pivotable, approximately rectangular door element 2 serves. Both the element 1 as well as the door element 2 represent glass plates whose thickness is 6 to 10 mm.

The hinge body 3 has a plate-shaped attachment area 6 on the outside, on the fixed element 1 is attached, in the upper, to the door element 2 pointing corner.

In the element 1 is in this corner a through hole or glass hole 21 intended. For fixing the mounting area 6 of the hinge body 3 serves an Allen screw 23 extending through a washer 24 ( 2 ), a fixing clamping disc 25 and a cone ring 22 as well as the hole 21 extends and into a threaded hole 26 in the attachment area 6 engages with its external thread. The edge of the hole 21 is conically chamfered, leaving the cone ring 22 not over the inside surface 27 of the element 1 rises. Also the Allen screw 23 , the washer 24 and the clamping disc 25 are designed so that they do not touch the inside surface 27 raise or protrude and thus inside the hole 21 are located. In the Allen screw 23 protrudes a pin, not shown, a cover 28 into it. The cover 28 is characterized by the Allen screw 23 held and is in the installed state approximately flush with the inner surface 27 ,

Also in the 4 to 6 shown hinged counter plate 4 gets outside on the door element 2 connected or fixed to this. This is a through hole 29 in the door element 2 which is also chamfered. Furthermore serve a cone ring 30 , a fixing clamping disc 31 , two fixing screws 32 , two cylinder sleeves 33 and two allen screws 34 , On these Allen screws 34 is a cover 35 attached, which as well as the cover 28 in the assembled state approximately flush with the inner surface 36 of the door element 2 is.

The door element 2 has in its upper left corner (viewed from the inside from the inside of the shower enclosure) in a plan view approximately rectangular recess 8th , in which the approximately also plate-shaped holding area 7 of the hinge body 3 so that the inwardly facing wall surface 37 approximately flush with the inner surface 36 is (see. 8th ).

In the holding area 7 of the hinge body 3 is an approximately cuboid, upwardly open cavity 9 except ( 3 ), who has a floor 10 has, in which a cylindrical through hole 11 located.

From the ground 10 starting two pins extend 12 to the top, which has an internal threaded hole 13 own, in each case an Allen screw 14 ( 2 ) engages with its external thread.

On the ground 10 is a bearing plate 15 and covers it in about. This bearing plate 15 has in supervision a slightly oval or rectangular shape and has a central through hole 16 and two laterally disposed through holes 17 whose inner diameter is approximately in the middle of the bearing plate 15 - based on its thickness - reduced, leaving a paragraph 18 is formed, on each of which a coil spring 19 rests.

The shape of the hole 17 with a smaller diameter in the bearing plate 15 is - seen in supervision - approximately conforming to the shape and size congruent with the cones 12 - also considered in supervision -. This shape is not circular disk-shaped. In addition, the dimensions are selected such that the bore 17 on the associated cones 12 can be postponed, a rotation of the bearing plate 15 however, it is prevented.

On the two coil springs 19 is a roughly cuboid abutment 20 on, but whose corners are rounded off. This abutment 20 is designed such that its peripheral outer surface 38 approximately parallel to the inner wall surface 39 of the cavity 9 runs.

The abutment 20 has two through holes 41 , which in supervision about surface and size congruent to the pin 12 are. The tips of the cones 12 come in these holes 41 to lie. These holes 41 are in a blanket 40 of the abutment 20 except. From this ceiling 40 extends a circumferential wall 42 - in the figures - down.

The holes 41 the cuboid or elongated abutment 20 are located in the two end areas. In the middle is the abutment 20 designed in the form of a cylinder sleeve. The inner bore 43 this cylinder sleeve has two sections of different diameter, with the larger diameter bore section at the top. At the transition between these two bore sections with different diameter, a shoulder is formed, which in plan view and thus in the direction of the axis of the bore has a circumferential annular surface 44 forms, which have several depressions in the form of troughs 45 has. In other words, the shoulder forms a curved surface or a lifting curve. Between the troughs 45 there is a raised area. The troughs 45 are arranged in 0 °, -90 °, + 90 ° and +/- 180 °. The wave troughs in +/- 180 ° and 0 ° extend in the longitudinal plane of the door element 1 ,

Through the inner bore 43 extends a cylindrical hinge pin 5 , which at its upper end a transverse bolt forming a sliding element 46 has. This cross bolt 46 also has a cylindrical shape and is in a transverse bore in the hinge pin 5 appropriate. This cross bolt 46 thus results in two cylindrical pins.

The hinge pin 5 goes at the upper end in a journal 47 over, in a bushing 48 is rotatably mounted and guided.

This bushing comes in a blind hole (not shown) of a closure plate 49 which are approximately rectangular in plan view and two through holes 50 owns, through which in each case an Allen screw 14 extends.

When assembled, the closure plate is located 49 on a heel 52 in the cavity 9 of the holding area 7 on and closes this cavity 9 flush to the outside.

The head-mounted Allen screws 14 extend through the associated hole 50 in the closure plate 49 as well as the associated bore 41 in the ceiling 40 of the abutment 20 and are with their external thread (not shown) in the threaded hole 13 in the cone 12 screwed. It goes without saying that the longitudinal axes of the Allen screw 14 , the hole 50 , the hole 41 and the threaded hole 13 are arranged in alignment. The allen screws 14 connect the closure plate with your head 49 with the cones 12 ,

When assembled, the cross pin is located 46 with its two end portions or end pins in a cylindrical shape on the annular surface 44 on.

Assuming that the cross bolt 46 in the troughs 45 at -90 ° and + 90 ° is and will be the hinge pin 5 rotated about its longitudinal axis by the hinge pin 5 firmly connected door element 2 is pivoted, then slides the cross bolt 46 on the sloping side surface of the troughs 45 along. Because the hinge pin 5 in the axial direction and thus in the direction of its longitudinal axis is not movable, is when turning the transverse pin 46 not the door element 2 raised. Rather, the abutment 20 which is movable in the axial direction and on the coil springs 19 rests against those of these coil springs 19 applied force - in the figures down - pressed until the cross bolt 46 has reached the wave mountain. This wave crest can also be plateau-shaped. This will ensure that the cross bolt 46 only if it is not in the trough and not on the plateau, but in an "oblique" area, the necessary energy is supplied by the coil springs 19 delivered the cross bolt 46 Press against the inclined surface while causing a sliding movement, which is used to rotate the hinge pin 5 leads. A guide of the coil springs 19 By the way, by the pin 12 achieved that in the interior of the coil springs 19 extend.

The hinge pin 5 protrudes down over the plate-shaped holding area 7 of the hinge body 3 out and comes in a recess 53 in the hinge counter plate 4 to lie. This recess 53 has an open elongated shape and is a half-shell, which in the on the outer surface of the door element 2 adjacent side surface 54 the hinge counter plate 4 is arranged. There is also a disc-shaped elevation in this area 55 which differs from that through the side surface 54 level formed rises and in the hole 29 in the door element 2 to come to rest. The recess 53 is thus located in the exact area of the disc-shaped elevation 55 and extends vertically from top to bottom.

The hinged counter plate 4 has in its upper part a horizontal (refers to the installed state) extending, in plan view approximately rectangular extension 56 on, a through hole 57 having a cross-sectional shape of a diked. Through this hole 57 protrudes the cylindrical hinge pin 5 through and comes in the elongated, also extending approximately vertically recess 53 or half-shell, located in the hinge counter plate 4 below the extension 56 located. The hole 29 in the door element 2 is near the bottom of the recess 8th of the door element 2 appropriate. The hole 29 is up to the recess 8th open. This connection area 51 is through the extension 56 filled in when the disc-shaped elevation 55 inside the hole 29 to come to rest. The extension 56 owns to the disk-shaped increase 55 towards such a shape that the bore 29 is completed, so to speak. The disc-shaped elevation 55 is dimensioned such that its side edge 58 as accurately as possible on the inner wall of the bore 29 comes to rest, leaving the game between hinge counter plate 4 and the door element 2 as low as possible.

In the disc-shaped elevation 55 are two laterally from the recess 53 arranged threaded holes 59 , in each of which a fixing screw 32 with its external thread screwed in (refers to the assembled state). The fixing screws 32 each extend through a through hole 60 with chamfered edge in the clamping disc 31 having a circumferential annular region and a bottom region in which these through-holes 60 are arranged. The fixing screws 32 , which are capscrews, press the clamping disc 31 and also the cone ring 30 into the glass bore 29 and grab - as I said - in the threaded holes 59 one. In this way, the clamping disc 31 in the hole 29 fixed.

The clamping disc 31 has two more through holes 63 on, through each of which a cylinder sleeve 33 extends through the interior of each of the Allen screws 34 protrudes and into a threaded hole 61 in the bottom of the recess 53 engages with its external thread. Overall, there are two such Allen screws 34 and also two threaded holes 61 available.

The threaded holes 61 are located in the valley area of the recess 53 ,

To the hinge pin 5 in the recess 53 to be able to fix, has the hinge pin 5 two long holes 62 on, whose longitudinal extent in the direction of the longitudinal axis of the hinge pin 5 runs. The distance between the centers of the oblong holes 62 , the through-holes 63 and the threaded holes 61 corresponds approximately to each other.

The allen screws 34 thus press with the help of the cylinder sleeves 33 attached to the outer surface of the hinge pin 5 come into contact, this in the recess 53 and fix the hinge pin 5 there, when they are dressed.

Due to the fact that the diameter of the hinge pin 5 is slightly smaller than the diameter of the same-thick bore 57 and thus also the half shell 53 as well as due to the fact that also the dimensions of the oblong holes 62 are slightly larger than the Allen screws extending through them 34 , is the hinge pin 5 slightly displaceable in several directions. In other words, the hinge pin 5 only then finally in the recess 53 with the help of Allen screws 34 and the cooperating further parts firmly fixed when the Allen screws 34 are attracted. The possibility for adjustment and fixation in the desired position is also supported by the fact that on the outer surface of the hinge pin 5 adjacent edge of the cylinder sleeves or clamping sleeves 33 bevelled or curved designed.

The swing door hinge according to the invention is flush on the inside of the shower enclosure, allowing easy cleaning with a Glasscheibenabzieher. In addition, the swing door hinge according to the invention allows the door element 2 both open to the outside and inward and to lock in different positions. The hinged door element 2 In addition, during the pivoting process performs no translational movement in the direction of the hinge pin 5 and thus from top to bottom and vice versa.

The parts of the swing door according to the invention Hinges can be made of a suitable metal and also of a suitable plastic. These materials are known to those skilled in the art, so that further discussion is unnecessary.
