Description: Door fitting

The innovation relates to a door fitting for a row of doors, each of which can be pivoted around a vertical axis, for closing the opening of cupboard furniture, niches, etc. To simplify the illustration, reference is always made below to a door fitting for a cupboard.

The previously known door fittings for barriers with a row of two or more doors usually consist of hinges or other types of rotary fittings that allow individual cabinet compartments to be opened or closed by turning or pivoting the door associated with the cabinet compartment. If the doors of several cabinet compartments are opened at the same time, the open doors often form undesirable obstacles and make access to the open cabinet compartments more difficult.

Although door fittings for sliding doors allow the opening of cupboard _compartments without there being an obstacle in the space in front of the cupboard in the form of a door pivoted into the opening position, sliding doors do not allow optimal access to the cupboard compartments if several adjacent cupboard compartments are to be accessible at the same time.

So far, no solution for a door fitting has been found that allows doors that are normally operated as revolving doors to be opened in special situations, for example

if several cupboard compartments are to be tidied, rearranged, put away or emptied at the same time,

f your space in front of the closet compartments.

f15

J The task is therefore to use the known

■ Types of door fittings for hinged and sliding doors

to create a door fitting that allows you to open and close cupboard compartments either individually by turning or _pivoting the doors or to open and close the doors of several adjacent cupboard compartments in

f to bring it into such a position that this cabinet

compartments are freely accessible.

The innovative solution to this problem provides that each door is hinged to a vertical element, the vertical elements can be moved and locked in parallel in the opening plane and the doors are coupled together by a connecting fitting so that they can be moved together.

Each door in a row of doors, which serves to close a corresponding number of cabinet compartments, is therefore mounted on a vertical element in a way that it can rotate or pivot, and each of the vertical elements is arranged in a parallel guide in the area of the opening plane of the cabinet in such a way that it is located together with the associated door in the opening plane.

can be moved together with the adjacent door, with which it is coupled via a connecting fitting. A joint movement of adjacent doors, possibly even of the entire row of doors, is possible by automatically rotating the doors that are moved together out of the opening plane by means of an appropriate design of the connecting fitting, which will be explained in more detail later. Each vertical element can be locked in a predetermined position in the parallel guide if the intention is to open and close the door individually in the conventional way by rotating or pivoting.

This design of the new door fitting allows -5 the following options for handling the doors:

1) All doors in the row of doors can be opened in the conventional way as revolving doors. This operation requires that the vertical elements assigned to the doors are locked in the specified position ⁱⁿ the parallel guide.

2) All doors are opened in the manner of a sliding register. To do this, the locks of the vertical elements are released. The first door is moved in the direction of the still closed neighboring door, whereby the vertical element assigned to the first door is moved parallel in the parallel guide accordingly. Due to the coupling between the first and the second

gO door by means of the connecting fitting^s, when the first door is moved further, the second door is taken along, whereby the second door simultaneously begins a rotational movement and its be it via the corresponding connecting fitting between the second

g ₆ and the third door takes the latter with it, also S|

by turning and the vertical element assigned to the third level moves parallel in the specified direction. At the same time, the

Connecting fitting that ensures that the doors always remain a certain distance from each other when they are moved together. At the end of the sliding process, all vertical elements with their doors are in a row next to each other at the end of the cabinet in the direction of movement, while the doors are parallel and a short distance from each other at the same end of the cabinet in the manner of a register, each in a perpendicular position to the associated vertical element.

All cabinet compartments are easily accessible and reachable as all doors are now removed from the opening area of the cabinet.

The doors are closed in reverse order until all vertical elements with their associated doors are locked back in the specified position.

3) With appropriate design of the connecting fitting and the locking mechanism, it is also possible to open and close part of the doors as a revolving door and another part of the doors as a sliding register.

Preferably, the parallel guide for each vertical element consists of a gear hidden on the element with upper and lower gears connected by a shaft, chain or the like.

QQ wheels, which are in engagement with a rack, pinion gear, chain or the like, which is attached to the top and bottom of the cabinet in the area of the opening plane. It goes without saying that for this type of parallel guide, the type and position

gg of the upper and lower gears and their connection and with regard to the toothed element on the cabinet side, a number of different designs are possible, as in connection with the explanation.

tion of preferred embodiments will become clear. It is essential for the design of the parallel gear unit that it is robust, maintenance-free and as invisible as possible on or in the vertical elements as well as on the cabinet. Naturally, smooth operation and the lowest possible costs for production and assembly also play an important role.

It is advisable for an upper carriage to be attached to each vertical element with at least one support roller, which is guided on a rail on the cabinet side. It is also advisable for a lower carriage to be attached to each vertical element with at least one guide element, in particular a guide roller with a vertical axis of rotation, which engages in a guide on the cabinet side. This design ensures that each vertical element with the door assigned to it is securely attached in the area of the door opening and at the same time can be moved safely and parallel to the door opening when the lock is released.

Preferably, the toothed element on the cabinet side, in particular the rack, is combined with the rail on the cabinet side for the support roller in one fitting in order to simplify the manufacture and assembly of the door fitting.

₃ Q For the same reason, it is also preferable that the lower toothed element on the cabinet side, in particular the rack, is combined with the cabinet-side guide for the guide element, in particular for the guide roller, in one fitting.

Finally, for reasons of simplification and cost, it is advisable that the door-side gear is mounted at the top and/or bottom together with the support roller of the upper carriage

or the lower guide roller are each mounted on a fitting.

For the function and handling of the locking mechanism for the vertical elements, it is preferably provided that each vertical element is in a predetermined position in which the associated door is
Swivelling, by a cabinet-side, located in the opening area of the cabinet and
can be locked using a locking device that can be operated by means of an actuating element.

A preferred embodiment of the locking device is characterized in that it consists of an L-shaped foot lever as an actuating element, which is pivotably mounted below the cabinet opening about a horizontal axis, the locking part of which is in the
Locking position under spring pressure with a part of the lower carriage of the associated vertical element or with it directly engages. In this embodiment of the locking device and the actuating element, the unlocking takes place by simply pressing down the foot lever, while the locking position is reached when the relevant

vertical element has reached its predetermined position and the locking part on the relevant part of the lower run of the vertical element under
Spring pressure engages without the need for any separate activation.

A beneficial further education is very important

the innovation, according to which the locking devices together comprise a locking bar formed from several segments arranged in a row, a _foot lever is arranged on each segment and the segment ends overlap or are connected to each other in such a way that when one segment is unlocked, the others also lock in one of the two directions

- to the right or left of the segment being operated - can be unlocked . This design means that in order to slide the doors together in register at the end of the cabinet or in another position, only one vertical element needs to be unlocked with the foot pedal, because the segmented locking bar simultaneously unlocks the vertical elements located adjacent in one direction.

For trouble-free and easy operation of the doors as a sliding register, the coupling of adjacent doors by means of the connecting fitting is essential. For this purpose, it is preferably provided that, for the joint opening of the doors, a cam guide is provided at the top of each door, which runs essentially across the width of the door and the associated vertical element, which in the area of the vertical element forms a slanting rearward guide towards the cupboard compartment.

Section with a side opening, through Z(J

a cam, in particular a rotating cam roller, can be inserted into the cam guide on a guide lever which is pivotally mounted at the top of the end of the neighboring door adjacent to the aforementioned vertical element. The connecting fitting is therefore preferably designed as an articulated connection. When a door is opened as a normal revolving door, its cam slides out unhindered via the side opening on the diagonally rearward section of the cam guide of the _Q _ neighboring door. Conversely, when the door is closed as a revolving door, the cam or cam roller goes back into the cam guide of the neighboring door. When the doors are opened as a sliding register, the cam guide of the door that is moved first takes over.

Door the movement, namely initially a pivoting 35

and then a shift or both types of movement combined, whereby the cam or cam roller of the second door first moves in the diagonally backwards

9 * t ♦♦#*#♦·* ·

running section and then slides in the threaded and door-parallel part of the cam guide and the cam always remains connected to the second door via the guide lever &igr; In this way, each door in the row of doors takes over the guidance of the next door in the direction of movement.

Preferably, a rail with an upwardly open cross-section and a U-shaped cross-section is placed on the door and the associated vertical element as a cam guide, so that the cam guide forms the upper end of each door.

The vertical elements are each designed to be as narrow as possible so that the doors pushed together as a register at one end of the cabinet form as narrow a package as possible, so that the cabinet compartment in front of which the door register is located remains accessible. Preferably, each vertical element is made of a narrow stud or a tube. A metal tube has the advantage that the connecting parts of the parallel gear can be arranged in the tube.

Within the scope of this application, protection is claimed not only for the new fitting but also for individual parts and units and in particular for cabinets that are equipped with the new fitting.

Examples of implementation of the innovation are explained below using the drawings. The drawings show:

The front view of a cupboard in Figure 1 illustrates an embodiment that when the innovative door fitting is used, the cupboard |

can be opened in various ways. Each of the doors 2a, 2b, 2c, 2d, 2e, 2f, with which the cupboard compartments e.g. 3d, 3e can be closed, is pivotally mounted on a narrow associated element 1, in the present case each formed by a door-high stud. This means that each of the doors 2a - 2f can be opened and closed individually by turning or pivoting. However, if several cupboard compartments are to be easily accessible at the same time, the relevant doors can be removed from the desired opening area by guiding the associated vertical elements 1 parallel to the side in the opening plane of the cupboard, as will be explained in more detail below. In the embodiment according to Figure 1, the cabinet doors 2d, 2e and 2f are arranged in registers, each with a small distance from one another and parallel to one another, at the right end of the cabinet, whereby they are perpendicular to the opening plane of the cabinet and to the associated vertical elements 1. As a result, the cabinet compartments 3 and 5 are freely accessible, while the doors 2a - 2c remain closed as desired. The vertical elements 1 are attached to an upper

2g cabinet-side rail 5 and a lower cabinet-side guide 10 and guided parallel to the opening plane of the cabinet. The new door fitting also ensures parallel guidance on the vertical elements 1 to the opening plane

₃ q vertical parallel planes, as will be explained.

Figure 2 shows how the doors 2a - 2e of a cabinet, which is divided into five compartments 3 - 3e, open and close in the conventional manner by turning or pivoting (see arrow 4a).

To simplify the drawing, the §

Doors 2a - 2e associated vertical elements 1, on which the aforementioned doors are pivotally mounted, not

shown.

Figures 3 and 4 show that all doors 2a - 2e can also be opened in a different way, as already explained with reference to Figure 1, by completely removing the coupled doors 2a - 2e from the area of the associated cabinet compartments 3a - 3e by parallel displacement of the elements 1 and arranging them at the right end of the cabinet in the manner of a register (see Figure 4). To do this, first the door 2a is opened by turning and sliding, as indicated by the arrow 4b, whereby the door 2a takes the neighboring door 2b with it (see arrow 4c), which in turn opens the door 2c and slides it along with it until the register position at the right end of the cabinet is finally reached. The drawn track 4d is intended to illustrate which intermediate positions, for example, the door 2a covers on the way from the first rotary opening to taking up the positions in the door register. Details for operating the joint parallel movement of the doors will be explained later. To close the cabinet compartments 3a - 3e, the doors 2a - 2e are returned to their original position in the same order, i.e. starting with door 2a.

Figure 5 shows that doors 2d and 2e of the two cabinet compartments 3d and 3e can optionally be opened as sliding registers (see arrow 4e), while doors 2a and 2b of the cabinet compartments 3a and 3b are opened in the conventional manner as individual revolving doors and door 2c of the cabinet compartment 3c, for example, remains closed.

In the first embodiment of a fitting according to the innovation according to Figure 6, a vertical element 1 shown in a shortened vertical section and thus its associated door (not shown) are mounted on an upper carriage 16 on an upper cabinet-side rail 5 approximately in the area of the opening plane of the cabinet, parallel to

j slidably or moveably mounted. A guide roller 11 of a lower carriage 17 of the vertical element 1 engages in a cabinet-side guide 10, so that the vertical element 1 is always held and slidable in a plane parallel to the opening plane. The . rail 5 is part of an upper fitting or profile 8, which is attached to the front edge of the upper cabinet base 6 running across the width of the cabinet (i.e. perpendicular to the drawing plane). The guide 10 for the ^Q guide roller 11 is part of a lower fitting or profile 9 running across the width of the cabinet and attached in the area of the front edge of the lower cabinet base 7, with the lower cabinet base 7 resting on a stud foot 7a at the front.

15

The upper carriage 16 is attached to the inside of the vertical element 1 by means of an anchor plate 12. A plate 13a angled from the anchor plate 12 into a recess in the vertical element 1 forms an upper bearing 13 for a shaft 14 arranged rotatably in the recess of the vertical element 1 that continues downwards, with a lower bearing 15 on a plate 15a that extends from the lower carriage 17 into the recess of the vertical element 1. The shaft 14 carries

_O{ - at the top a spur gear 18 which engages in the manner shown in an almost concealed upper rack 19 within the upper profile 8, while a spur gear 20 arranged at the bottom of the shaft 14 with a corresponding lower

Profile 9 arranged lower rack 21 meshes. This oU

Gearbox serves to guide the vertical element 1 in parallel and ensures that the vertical element 1, when it is moved on the upper rail 5, always remains in planes parallel to the drawing plane _and - seen from above - does not assume an inclined position

you

For example, the upper part of the vertical element 1, when it is moved on the rail 5, can be filed.

The sectional view in Figure 7, which corresponds to a similar embodiment as in Figure 6, once again illustrates in a top view a possible mutual assignment of the vertical element 1, which is designed here as a stud, the associated door 2 connected to the vertical element 1 via a hinge 23, as well as the two support rollers 22 of the upper carriage 16 on the rail 5 and finally the upper gear 18, which is arranged predominantly in the recess of the vertical element 1.

The representations in Figures 8 and 9 correspond essentially to the representation of the lower part of Figure 6, so that the parts provided with the same reference numerals do not need to be explained again. In addition, however, in Figures 8 and 9 a locking device 24 is arranged below the cabinet opening in the position shown and is integrated with the lower carriage 17 and the lower profile 9 in the manner shown. To form the locking device 24, a foot lever 26 with an L-shaped cross section is mounted on the profile 9 behind the guide 10 so as to be pivotable about an axis 25.

In the locking position shown in Figure 8, a locking part 28 of the foot lever 26 is brought into engagement with a part 30 of the lower carriage under pressure by a spring 29, so that the vertical element 1 ^is held in the predetermined position of the cupboard opening.

To unlock the locking device 24, the foot lever 26 is pressed downwards (see arrow 27) until it reaches approximately the position shown in Figure 9, in which the part 30 of the lower carriage 17 is disengaged from the locking part 28 and the vertical element 1 is consequently freely displaceable.

»f

The locking devices 24 of the vertical elements of a cabinet are expediently connected to one another in such a way that when one locking device 24 is unlocked, all the other vertical elements 1 located in a direction in which the vertical elements 1 are to be moved are also unlocked at the same time. For this purpose, the locking devices 24 each consist of a locking bar 32 extending across the width of the cabinet, which is formed into individual segments 31, each assigned to one of the vertical elements 1, which overlap one another (see Fig. 19). For operation, each segment 31 has a foot lever 26 extending forwards in the manner of a footrest. With reference to the representations of the opening options in Figures 2 to 5, one of the locking devices not shown in the above figures must be actuated for the doors that are to be moved in one of the register arrangements according to Figure 4 or 5. Conversely, the locking devices 24 of the doors that have been returned to their position from the register arrangement must be locked again, for which purpose an automatic locking by the spring 29 is provided.

In contrast to the first embodiment according to Figure 6, in the embodiment according to Figure 10 the vertical element 1 consists of a metal tube to which the associated door 2 (not shown) is pivotally attached and in which the element-side parts of the gear for the parallel guide, namely the shaft 14 (shown without bearings) and the upper and lower gears 18 and 20 are arranged. The latter mesh with an upper and lower rack 19 and 21, respectively, which are attached to the front of the upper and lower cabinet base 6 and 7, respectively. The upper cabinet-side profile 8 with the rail 5 for the support rollers 22 of the upper carriage 16 is separated from the rack fitting in this embodiment. The same applies to the lower profile 9 with the guide 10 for the guide

roller 11. Otherwise, the same reference numerals in Figure 10 refer to the same parts of the previously described embodiment / so that a further explanation can be omitted. In the following descriptions of the other embodiments, parts already explained ' are not explained again. With reference to Figure it should also be pointed out that the upper carriage fitting is designed in such a way that the support rollers 22 in the upper carriage 16 are arranged concealed, while the rail 5 of the upper profile 8 is exposed.

In the third embodiment according to Figure 11, the shaft 14 with the gears 18, 20 is mounted off-center in the vertical element 1, which is also tubular, as shown, with the upper bearing point 13 being shown. This arrangement allows the upper and lower racks 19 and 21 to be installed in a recess on the front side of the upper and lower cabinet floors 6 and 7, respectively, so that the racks 19, 21 are arranged set back within the floors.

In the fourth embodiment according to Figure 12, the element-side parts of the parallel guide gear are arranged outside the vertical element 1, which is also tubular as in the two previous embodiments. For this purpose, the upper carriage 16 attached to the vertical element 1 has an extension 33 angled towards the cabinet with the upper bearing point 13 of the shaft 14, while the lower carriage 17 has an extension 34 angled towards the cabinet with the lower bearing point 15 of the shaft. The racks 19, 21 are each provided as a separate profile fitting in a recessed position below the upper cabinet floor 6 or in a recessed arrangement on the lower cabinet floor 7 for engagement with the gears 18 and 20, respectively, so that these are always concealed even outside the vertical element 1.

&igr;···· · ¹ V ₁ *.

In the fifth embodiment according to Figure 13, a bevel gear is arranged within the vertical element 1, which is also tubular in this case. The shaft 35 of one of the support rollers 22, which is concealed in the upper carriage 16, is extended laterally into the vertical element 1 to accommodate a pinion 18a. This meshes with the upper gear 18, which is designed as a bevel gear, which, like the lower gear 20, which is also designed as a bevel gear, is arranged on the shaft 14, which in turn is rotatably mounted in the vertical element 1. The lower gear 20 meshes with a corresponding pinion 20a, which is cantilevered on a shaft 36 mounted in the lower carriage 17. The shaft 36 carries a lower roller as a guide element 11, which is in engagement with a lower rail 39 via a toothing 38. Accordingly, the rail 5 and the support roller 22 of the upper carriage 16 have a toothing 37, so that the rail distances covered on the rails 5 and 39 by the lower and upper carriages 17 and 16 are always the same, since the gear circuit is closed via the gear parts arranged inside the vertical element 1. The locking device 24 arranged below or behind the lower carriage 17 and the lower profile 9 is designed in a similar way to the locking device 24 shown in Figure 19.

The sixth embodiment according to Figure 14 differs from the previously described fifth embodiment according to Figure 13 primarily by a toothing that is separate from the upper support roller 22 and a corresponding design at the lower end of the gear train. The shaft 35 of the support roller 22 included in the gear train, on which the pinion 18a is mounted in a floating manner at the right end, carries a string-toothed gear 40 at its end leading out of the upper carriage 16 to the left (with reference to the drawing), which meshes with a rack 41 on the upper profile 8, while the two support rollers 22, of which only one support roller is shown in the drawing

&bull; · « * « ill

shown/ only serve to suspend and move the vertical element 1 and the associated door (not shown) on the rail !?. Accordingly, a serrated gear 42 is arranged on the shaft 36 in the lower carriage 17, which meshes with a rack 43 formed on the lower profile 9. The lateral guidance of the vertical element 1 can be taken over jointly by a guide roller 11 in conjunction with the gear 4 2 within the guide 10.

1Ö ISs However, it is also possible to arrange the gear 42 and a guide roller one behind the other in a direction perpendicular to the plane of the drawing, as is used in the previous embodiments, e.g. according to Figure 12. The solution shown in Figure 14 has the advantage, as in the embodiment according to Figure 13, that the cabinet-side elements of the gear train for parallel guidance are located outside the cabinet space and, like the carriage-side parts of the gear train, remain largely invisible to the viewer or user of the cabinet. Compared to the embodiment according to Figure 13, there is a clearer separation of the functions of support and synchronous running on the upper and lower profiles 8 and 9 and the associated parts of the carriages.

In the seventh embodiment according to Figure 15, the upper profile 8 is arranged as a whole below the upper cabinet floor 6. The rack 5 is arranged on the front side of the box-shaped profile 8 in such a way that a recess extends above the rail in which the upper carriage 16 with the support rollers 22 can be moved on the rail 5. The upper rack 19 is formed in a recessed position between the upper cabinet floor 6 and a step on the upper side of the profile 8. The upper gear 18 meshes with the rack 19 arranged in a groove in this way, and in a corresponding manner the lower gear 20 is in contact with a similarly formed lower profile 9.

&bull; · ' · · &Igr;&bgr; 1 ft * >

The rack 21 engages, with the profile 9 again being completely below the relevant cabinet floor 7. Behind the rack 21 is the guide 10 for the guide roller 11 of the lower carriage 17. The vertical element 1 consists of a hollow body made of metal in which the upper and lower bearings 13 and 15 of the shaft 14 are arranged.

With regard to the IQ embodiments of the innovation shown and described, it should be noted that mixed forms are also conceivable insofar as the design of, for example, the upper profile as well as the upper carriage and the other guide elements arranged in the upper part of the cabinet of one embodiment - 5 can also be combined with a form of the lower carriage as well as the lower profile and the other guide elements arranged in the lower part of the cabinet of another embodiment, provided that the respective design allows such a combination.

The coupling of the doors 2 shown in Figures 16-18 for the joint opening and arrangement of several doors 2 in the manner of a register (see Figures 4 and 5) comprises cam guides 45 which are U-shaped in cross section, preferably open at the top and are arranged above the doors 2 and the associated vertical elements 1 on these, in each of which a cam roller 48 is guided. This is located at the end of a guide lever 49 which is pivotally mounted at point 50 on a door stud 44 of the respective adjacent door 2. When closing ^the neighboring door 2 by turning or pivoting, the associated cam roller 48 engages through an opening 47 on a section 46 of the guide 45 that is guided obliquely to the rear, so that each door is coupled to the previous door in the closed position via its guide 45 or 46. The associated section 46 of the guide 45 is located in the position shown above the vertical element 1 of the associated door.

2, which is pivotally connected to the vertical element 1 via the hinge 23.

If at least two doors 2 coupled together are to be opened together and arranged together in a register at the end of the cabinet, as was explained in connection with the description of the illustration in Figure 4, for example, the lock of the door furthest away from the location of the door register to be formed is first unlocked, whereby the other doors intended to be moved or their vertical elements 1 are also unlocked. This first door is then opened by a certain angle and moved by an initial distance, whereby its guide 45 with the section 46 changes its position. As a result, the cam roller 48 (see arrow 51) slides along the section 46 of the neighboring door 2, and the guide lever 49 performs a clockwise rotation (see arrow 53) by an angular amount as the movement continues. The neighboring door 2 is moved by turning and moving {see arrow 53}. Arrow 52) is opened in the manner already described in connection with the illustration in Figure 4. Further intermediate positions of the adjacent, coupled doors 2 are shown in Figures 17 and 18. At the end, the doors reach a distance

_ ₅ parallel position perpendicular to the opening plane of the cabinet in the manner of a register, as has already been repeatedly explained. Arrows 54, 55 and 56 indicate corresponding relative movements of the coupled or engaged parts.

The illustrations in Figures 19 to 27 are largely self-explanatory based on the previously explained figures of the various embodiments, so that only supplementary information is given below to avoid repetition.

From the exploded view of an embodiment, which includes the views of Figures 19-21 , it is clear that the door 2 is secured to at least one tubular

1 material formed vertical element 1 over a

is rotatably mounted on the vertical element 1 hinge-B fitting 57, which is in each case in a corresponding

-.. the corresponding height of the fitting 58 with a dovetail-shaped recess is inserted into the door.

The remaining components and details in the above figures as well as in figures 23 - 27 are understandable in terms of their form, function and arrangement, ^so that ^only individual reference symbols are used.
