Abstract

The fastening has two rectangular doors (8,9), which are parallel to each other and run in side guides (17,24). The two fastening elements are movable from their fastened position in which they are adjacent and do not overlap into an open position in which they completely or nearly completely overlap, and vice versa. The top and bottom parts of the side edges of the doors have guide-pieces (15,16,21) running in the guides belonging to each door and spaced so that the doors can overlap. The doors are joined by at least one flexible pull (31) running over a deflector roller (30) to a fixed point (35,36).

Description

The invention relates to a closure for openings of all kinds, preferably for furniture, e.g. Cabinets.

In openings, such as window openings, but especially in openings of furniture, such as openings of cabinets, there is a need to provide them with closures that can be opened and closed to save space and appear in an attractive manner in appearance. Usually, as a closure wing-like pivotable doors or flaps are provided, however, to open a considerable amount of free space in front of the opening require, which is often not available.

Out FR-A-2 339 045 a closure is known, with two guided in lateral guides closure elements, which are from its closed position in which they lie substantially free of cover next to each other, in their open position in which they completely or almost completely overlap, and vice versa, wherein the closure elements are provided with guide pieces that run in such each closure element associated guides that they at least have such a distance from each other in the overlap area that the closure elements can be pushed over or under each other, and the closure elements are interconnected by a flexible tension element.

The flexible tension element extends from the one lower edge region of the one closure element via a fixed deflection roller to a lower edge region of the other closure element. The two closure elements are thus balanced over a cable. When opening the shutter, the two closure elements move in opposite directions at the same speed and move in a middle position on top of each other, so that the openable space is only half open.

The object of the invention is to provide a closure of the type specified, in which release the closure elements after the sliding over the opening space.

According to the invention, this object is achieved by two guided in lateral guides, arranged parallel to one another and substantially rectangular, plate-shaped closure elements, which from their closed position, in which they lie substantially free of cover next to each other, in their open position in which they completely or almost completely overlap , are displaceable, and vice versa, wherein the closure elements are provided in the upper and lower region of its side edges with guide pieces which run in each closure element associated guides which have at least in the overlap region such a distance from each other that can let the closure elements over or push each other , And that the closure elements are interconnected by at least one flexible tension element, the practice of a fixed point in the region of the closing side of the opening, on which move the closure elements when closing r a deflecting guide, for example, a deflection roller, which is arranged in the outer edge region of this closing side opposite closure element, extending to a fixed point at the edge facing in the opening direction edge region of other closure element.

The closure elements according to the invention can be easily moved between their closed and their open position, because they can be performed with little friction on their guide pieces in the lateral guides. By the flexible tension member, the closure elements are coupled in such a manner that the rearward in the opening direction closure element is moved at twice the speed of the front closure element in the open position when the front provided with a handle closure element is pushed into the open position, so that both closure elements at the same time reach their open position, in which they substantially overlap, whereby the openable space is released. The closure elements can be moved back into its closed position, characterized in that the closing element located in the front closing direction is pulled into the closed position, whereby due to the flexible tension element, the other closure element is tightened.

According to an inventive development, it is provided that the closure elements lie in their closed position substantially in a common plane and that the guides for the guide pieces, which are in the region of the closure side facing side edge of the closure element opposite thereto, approximately at right angles to the direction of displacement having sections have, which run over curved pieces in the direction of displacement in the main sections of the guide, so that the front opening in the opening direction closure element can be pulled out so far from the common plane under pivoting about its outer guide pieces, that can be the trailing closure element push under this. According to this embodiment, the closure elements are in their closed position substantially in a common plane, so that they convey an appealing and calm appearance. Although the closure elements in their closed position as it were dull together with their facing narrow sides, a trouble-free opening is ensured by the fact that the rear end of the front opening in the opening direction closure element is pulled out of the plane and moved in the opening direction, so that the trailing closure element is tightened and retracts under the leading closure element.

In a further embodiment of the invention, it is provided that guides are provided for the guide pieces of the closing side opposite closure element, which are located in the region of the lying in the opening direction ends of the side edges, which have obliquely extending initial sections. These obliquely extending initial sections also lift the section of the closure element leading in the opening direction out of the plane of the trailing closure element, so that the closure elements can be moved into a closed position in which they are congruent and parallel to one another.

The closure elements according to the invention are intended to be used mainly for vertical openings, such as the opening sides of cabinets.

According to a preferred embodiment, it is therefore provided that the closure elements are displaceable in the vertical direction and on the upper closure element, a spring-loaded tension element is attached, which tends to pull this upwards. The tension element is expediently acted upon by a force which compensates for the weight of the closure elements, so that substantially only frictional forces are to be overcome when opening and closing the closure elements.

The weight compensation serving tension element is expediently acted upon by a gas spring or a coiled spring.

According to another preferred embodiment, it is provided that the sections extending at right angles to the direction of movement of the guides consisting of grooves have latching recesses for the guide pieces in their closed position in their upper flanks. By this recesses the upper closure element is held in its closed position.

Conveniently, the guide pieces consist of rollers. It can be provided rollers which are mounted on mutually perpendicular axes, so that the closure elements are guided both in the vertical direction and in the horizontal direction.

The guide pieces can be attached to angled brackets, so that the guides for these can be arranged on the insides of the side walls of cabinets.

Appropriately, the flexible tension elements are attached to both sides of the closure elements, so that a tilt-free displacement of the closure elements is ensured.

According to an inventive development, it is provided that the closure elements lie in their closed position substantially in a common plane, in that the guides for the guide pieces of both closure elements run parallel to one another and the guides of the lower closure element in the direction of the open position in which the closure elements overlap each other, enclose the guides of the leading upper closure element between them and the closure elements, that the initial regions of the guides are curved from the closed position of the trailing, lower closure element such that this passes over the leading closure element overlapping, and that acts on the upper closure element, a tension member, the tensile force is at least so great that this moves the upper closure element from the closed position to the open position. This second embodiment of the closure according to the invention differs from the first embodiment described above essentially in that the lower closure element overlaps the upper when moving into the open position, that is not inserted under the leading upper closure element. The particular advantage of this embodiment is that the closure is easier to open and close, because the lower closure element can be moved to open and close, which moves relative to the upper closure element at twice the speed and therefore can be moved accordingly easier. Since the lower closure element can not drag the upper closure element when moving into the open position, a tension member must act on the upper closure element, which moves the upper closure element from the closed position to the open position. When pulling down the lower closure element in the closed position of this, the upper closure element is taken by the described flax draw-type shearing. In order to move the lower closure element easily and quickly, it is expediently provided with a handle.

Conveniently, the lower guide pieces of the trailing closure element are guided in the downwardly extended guides of the leading closure element. In order to prevent running in the same guides each lower guide pieces of the upper and lower closure elements collide in the open position, the guide pieces of the upper closure element are correspondingly further offset upwards.

The tension member may consist of a spring. Advantageously, however, the tension member is a running over at least one pulley rope to which a weight is attached.

The weight may consist of a carriage running on a guide rail. The carriage may comprise a metal plate provided with means for attaching further weights so that they may be added as needed. The car can also consist of a container that is optionally met by ballast.

According to a preferred embodiment it is provided that the weight of another weight is attached by a collapsible or collapsible tension member, which is effective only in the initial phase of the opening and then becomes ineffective by starting a supporting this base. This embodiment takes into account the fact that at the beginning of the displacement of the lower closure element, a greater force is desired to automate this initial phase and the same time to grant the required closing force.

The weight may be attached to a conventional pull-out rail of a pull-out guide for drawers. In this case, the additional counterweight can be connected to the center rail of the pull-out, the kinematics of the pull-out already takes into account the fact that the additional counterweight is ineffective after a certain distance by placement on a pad.

According to a preferred embodiment it is provided that the counterweights, ropes and guides are arranged on the outside of the cabinet and covered by a panel, such as a plate. This embodiment ensures that the entire interior of the cabinet is free and objects do not come into contact with the mechanism for moving the closure elements.

In the simplest embodiment, a single counterweight is provided and this is adapted to the weight of the closure elements, that they remain in any position.

Since act on the lower in the closed position closure element no forces, it is provided in this case that in the approximately perpendicular to the guide extending end portions of the guides for the guide pieces of the lower closure element resilient elements or magnets are arranged, the guide pieces or their roles Press in recesses. In this way, a good and secure closure position of the lower closure element is ensured.

The cabinet shown in FIGS. 1 to 3 consists of a body part with side walls 1, 2, a rear wall 3 and bottom and top walls 4, 5. The cabinet is provided with an upper intermediate wall 6, which in an upper compartment 7, which is open in the closed position of the rectangular closure elements 8, 9, and a lower compartment 10 which is opened when the closure elements 8, 9 have been moved to their upper, mutually overlapping position in which they close the compartment 3. For actuating the closure elements 8, 9, the upper closure element 8 is provided in its lower central region with a knob-shaped or bow-shaped handle 11.

At the outer edge regions, the inner sides of the side walls 1, 2 are provided with guides 12 for guide rollers of the closure elements, which are explained in more detail with reference to FIGS. 4 to 6.

The lower closure element 9 is provided on both sides in the region of the upper sides of the lateral edge regions with angled support pieces 13, 14, whose rectangular angled mounting legs 13 ', 14' in the manner shown in particular in FIGS. 7 and 8 are bolted to the lower closure element 9 , At the right angles to the closure element extending inwardly projecting legs of the support pieces are three perpendicular rollers 15 freely rotatably mounted on perpendicular to these axes, of which the outer two rollers 15 on the outer edge 16 of the guide groove 17 and the middle roller 15 on the inner Flank run in the manner shown in Fig. 7 way. On the support piece 13, a further roller 16 is freely rotatably mounted about an axis which is perpendicular to the axes of the rollers 15. The roller 16 runs on the web portion of the guide groove 17, so that a straight and tilt-free run the lower closure element 9 is ensured in the rectilinear guides 17. The linear guides 17 extend substantially over the entire height of the insides of the side walls of the cabinet.

The screwed on both sides of the insides of the side walls guides consist of molded plastic parts 18 which are provided on their inner sides with the linear guide grooves 17 and on their outer sides with the guide grooves 19, 24 for the upper and lower guide rollers 21, 22 of the upper closure element 8.

The guide grooves 19 for the lower guide rollers 22 consist of a main portion 20 which extends parallel to the guide groove 17, and a lower approximately at right angles bent guide portion 20 ', the end region is approximately at right angles to the guide groove 17. The upper flank of the guide groove 20 'is provided with a rounded recess 20' in which the guide rollers 22 rest in the closed position shown in FIG. 4.

The upper guide grooves 24 also consist of an upper parallel to the guide groove 17 extending portion 24 'and a lower inclined portion 25th

The guide rollers 21, 22 are mounted in the manner shown in particular in FIGS. 7 and 8 on support pieces 26 which are formed as angle pieces, one leg 27 are screwed to the closure element 8. At the other inwardly projecting legs 28, the rollers 21, 22 are mounted.

On the upper support pieces 26 are freely rotatably mounted on axes pulleys 30, over which a flexible cable 31, for example a rope of steel wire, runs, one end of which is attached to a fixed point 32 in the lower end of the guide grooves provided with the fitting 18 and the the other end is respectively secured to the upper support pieces 13 of the lower closure elements. To fasten the ends of the rope provided with holes holding pieces 35 are provided, the holes are cut at right angles by threaded holes, are screwed into the screws 36. By the screws 36, the introduced into the holes ends of the cables 31 are clamped.

In holes 37 of the upper support pieces 26 arranged holding parts 38, the ends of a flexible cable 40 are held by the holes 37 crossing clamping screws 39. The flexible cables 40 run over guide rollers 41 in the upper region of the guide pieces provided with the shaped pieces 18, via guide rollers 42 which are mounted on bolted to the side walls of the cabinet bearing pieces 43, and guide rollers 44 which at the outer ends of the piston rods of gas springs 45th In Fig. 4, the positions of the guide roller 44 are shown in shifted in the closed position closure elements 8, 9 in solid lines, while the position of the guide rollers 44 'in the of Fig. 6 apparent Opening position of the closure elements is indicated by dashed lines.

A different embodiment of the guide of the closure elements 8, 9 will now be described with reference to FIGS. 9 to 10, which differs from that of FIGS. 4 to 6 in that the lower closure element when moving the closure elements 8, 9 in the open position overlapping over the upper closure element and in the manner shown in FIGS. 10 and 11 is outside.

On the cabinet side walls guides of the type described with reference to FIGS. 7 and 8 are fixed in the edge region of the opening side, in which the rollers of the guide pieces of the closure elements 8, 9 run.

The upper closure element 8 is provided with upper and lower guide pieces 50, 60, on which the rollers 51, 61 are mounted, which are guided in the outer guide rail 52. The guide rail 52 extends substantially over the entire height of the side wall 53 of the cabinet 54th

Offset inwardly are attached to the cabinet side walls 53 adjacent to the outer guide rail 52 and parallel to this guide rails 55, in which the rollers of the upper guide pieces 56 of the lower closure element 9 are guided. The guide pieces 56 of the lower closure element 9 are made so long that they engage over the outer guide rail 52.

The lower end portions of the inner guide rails 55 are provided via a curved portion with a rectangular bend 57, in which lie in the closed position, the rollers of the upper closure members 56 of the lower closure element 9. The lower end portion of the guide 52 is provided with an obliquely inwardly extending guide piece 58 with a straight end piece 59 in which the rollers of the lower guide pieces 62 of the lower closure piece 9 are in the closed position.

The two closure elements 8, 9 are connected by a cable 64 like a pulley. The cable 64 runs from a lower fixed point 32 in the region of the bottom of the cabinet via a deflection roller 30, which on the upper Führungsstükken 50 of the upper closure element 8 is mounted, to a fixed point 35 on the upper guide pieces 56 of the lower closure element. 9

At the upper guide pieces 50 of the upper closure elements 8, the ends of cables 67 are fixed in fixed points 66, which run over rollers 68 in the upper end region of the guide rails 52, 56 and a guide roller 69 and at the other end a counterweight 70 is attached.

The closure elements 8, 9 are in their apparent from Fig. 9 position in its closed position in which they are aligned with each other in a plane.

To open the cabinet, the lower closure element 9 is provided at its upper end with a handle, not shown, through which the upper end portion in the direction of arrow A can take off so far that the lower closure member 9 is in a slightly tilted position, in the the upper edge of the lower closure element 9 can drive over the lower edge of the upper closure element 8 bumpless. The extension distance is determined by the length of the angled branches 57 of the guide 55. Now, if the lower closure element moved up, run the guide rollers of the lower guide pieces 62 of the lower closure element 9 via the oblique branch 58 of the guides in the guides 52 a. Now, if the outer closure member 9 is shifted upward, the guide rollers run in the mutually parallel straight guides 52, 55, so that the outer closure member 9 is in a direction parallel to the upper closure member 8 level and in the from Figs. 11 and 12 overlapping and overlapping over the upper closure element 8 can be pushed. The upper closure element 8 is automatically moved by the counterweight 9 at half the speed of the lower closure member 9 up until the closure elements 8, 9 overlap each other in the apparent from Fig. 11 open position.

The upper guide pieces 50 form for the Seileinscherungen as rope bottles, the counterweight is so dimensioned that it is not only the upper closure element 8 when lifting the lower closure member 9 moves automatically upwards, but additionally also exerts a relieving force on the lower closure member 9 in such a way that both closure elements remain in their respective position.

Since the lower closure element 9 moves due to the rope collapse at twice the speed of the upper closure element 8, the lower closure element can be moved with little force in its closed position.

In the embodiment shown in FIGS. 9 to 11, the counterweight 70 is guided on a pull-out rail 72 of a pull-out guide for drawers. An additional counterweight 73 is connected to the center rail 74 of the drawer slide pull-out system. The carcass rail 75 of the pull-out rail system of the drawer guide is bolted to the cabinet side wall 53. The counterweight 73 bearing center rails 74 are attached by carriages on the slide rails. The pull-out of drawer guides is known per se and therefore need not be described in detail.

As is apparent from Fig. 12, the guide pieces for the closure elements 8, 9, the guides and the cable shingles are arranged on the outside of the side walls 53 and covered by a cover plate 80.

From Fig. 13 it can be seen that the extending approximately at right angles to the guide rails 52, 55 end piece 57 is provided on its underside with a resilient element 82, that in the end piece 57 of the guide incoming rollers in a recess consisting of a detent recess 83 in depresses the top of the guide piece.

From Fig. 14 a to be fastened to the side walls 53 of the cabinet guide rail 85 can be seen, on which a carriage over the rollers 86 is slidably guided, which carries a plate 87 as a counterweight. The plate 87 is keyhole-like Holes 88 provided, in which additional weights can be hung for the purpose of Austärärens.
