1. Field of the Invention
The invention relates to a furniture closure for doors, flaps and drawers, which in each case cover an opening of the furniture item or are received in the opening, contact surfaces of the door or flap or a front panel of the drawer projecting over the opening and engaging in the closed position on a mating surface of the furniture item.
The invention is fundamentally suitable for all furniture items having doors, flaps and/or drawers. However, the invention is particularly intended for cabinets and the like in the vehicle sector, i.e. for land vehicles, water craft and air craft, in which it is necessary to ensure a secure closure in virtually all positions and in substantially all circumstances. A preferred field of use is constituted by air conditioning cabinets, e.g. heating, cooling or freezing cabinets, in which the products to be kept hot, cold or frozen are stored in compartments and/or drawers.
2. Related Art
In order to achieve air conditioning with a minimum energy consumption it is necessary to have a tight seal of the compartments and drawers, whilst simultaneously allowing a secured closure, as well as an easy, rapid opening and reclosure.
It is known to provide circumferential sealing profiles on doors or also on mating surfaces, which surround a cabinet compartment or a furniture opening for a drawer and against which strikes a door, flap or front panel of a drawer. Generally sealing profiles constructed in bellows-like manner or also magnetic seals are used, which assist the closure of the flaps, drawers, doors and the like.
For closing purposes use is made of magnetic closures, pressure closures or spring elements.
Magnetic seals are relatively costly and not suitable for any drawer or compartment construction. In addition, cold spots can arise, which have a disadvantageous effect. A disadvantage of bellows seals is that they cannot be cleaned or can only be cleaned with significant effort and therefore there is a risk of bacteria being introduced into the air conditioning cabinet whenever the door, flap, etc. is closed.
The object of the invention is to provide a furniture closure, particularly for cabinets and the like in the vehicle sector, which has a particularly simple construction and an inexpensive manufacture and which ensures a tight, secured closure and an easy opening of doors, flaps and drawers and which permits an efficient cleaning, particularly of the seal.
According to the invention this object is achieved by a furniture closure for doors, flaps and drawers, which in each case cover an opening of the furniture item or are received in the opening, contact surfaces of the door or flap or a front panel of the drawer projecting over the opening and engaging in the closed position on a mating surface of the furniture item, wherein the door, flap or front panel is provided in a marginal area with a profile rail, which is equipped with a seal and a locking member and which is movable from a closed position into an open position and vice versa.
It is a fundamental principle of the invention to equip a door, flap or drawer with a closure construction, which exerts a tightening torque and ensures locking and unlocking, together with pivoting of the door, flap and drawer from an open position into a secured closed position and vice versa.
According to the invention a furniture closure for doors, flaps and drawers, which in each case cover or are received in the opening of a furniture item, contact surfaces of the door, flap or a front panel of the drawer projecting over the opening and engaging in the closed position on mating surfaces of the furniture item, has a profile rail, which is marginally located, e.g. in an upper or lateral area of the door, flap or front panel. The profile rail is provided with a seal and with a locking member and can be pivoted from the closed position into an open position.
It is advantageous that the profile rail is constructed for receiving a seal with spring action and that the profile rail with the seal, which serves as a spring element for the closure position, as well as the locking member can be moved about a horizontal axis. As a result of its spring tension the seal presses the locking member into the locking position, so as to ensure secured locking of the door, flap or drawer without an additional spring element.
When positioned in an upper area, e.g. of a flap or front panel, the seal and the profile rail can extend over the entire width of the upper area of the door, flap or front panel of the drawer, a seal sealing the entire furniture opening and is also located on the longitudinal sides and on the lower transverse side.
Use is made with particular advantage of seals having a high spring tension and which keeps the locking member in the closed position. Preference is given to seals made from an elastomeric plastic or foamed rubber. In addition, lip seals and cellular seals are advantageous.
Appropriately a springy seal with insulating characteristics is used for the furniture closures of air conditioning cabinets.
The pivot pin located in the longitudinal direction of the profile rail is appropriately constructed in hinge or joint-like manner. The profile rail can also be movably fixed with the aid of a band or elastomeric hinge, a pivot joint or by pivot pins to the door, flap or front panel of a drawer.
For opening and closing the door, flap or drawer the profile rail is advantageously provided with a gripping strip. To limit the pivoting movement of the profile rail from the closed position into the open position at least one tilt stop is also provided.
In a particularly simple constructional variant the profile rail can have a cross-sectional roughly I or T-shaped construction, whilst having a vertical leg relative to an arrangement on an upper area of the flap, front panel, etc. The vertical leg can be used for fastening the profile to the side of the door, flap or drawer front panel facing the furniture opening and can e.g. receive a hinge, which can be spring biased.
The horizontal leg can have an asymmetrical or an outwardly beveled construction and terminally passes into the gripping strip. In a further variant the horizontal leg of the profile rail can be provided on an inside with a fixing strut for anchoring the seal.
In a further variant the profile rail can be constructed in two parts and a first part has a joint, e.g. a universal or shaft joint, whilst the second part has a joint receptacle, e.g. a universal or shaft seat, in which the joint is received and the horizontal axis of the profile rail formed. The first part of the profile rail has the vertical leg with the seal anchored therein, e.g. in the form of a lip seal, as well as the horizontal leg with the terminal gripping strip. The second part of the profile rail with the joint receptacle or joint seat and two fastening legs arranged at an angle are used for fastening purposes, particularly to an upper area of the door, flap or extraction front of the drawer, e.g. with the aid of a knuckle joint.
Appropriately the knuckle joint extends over the joint seat with the universal or shaft joint received therein and passes into a tilt stop, which limits the pivoting movement of the first profile rail part in the open position.
The locking member can be rigidly fixed to the profile rail, appropriately to the vertical leg. It is also possible to integrate the locking member into the profile rail. The locking member projects roughly at right angles from the vertical leg of the profile rail into the opening of the cabinet body and cooperates with a strip, advantageously a taper gib strip, or a slot on a surface surrounding the furniture opening.
The profile rail can be made from metal, e.g. aluminum, or from a plastics material, e.g. PVC. The locking member can be produced in the same way.
Appropriately the seal is constructed in such a way that a linear or flat, sealing engagement on the mating surfaces of the furniture body is ensured. It is particularly advantageous to have seals, which can be compressed and provide a spring tension for moving the profile rail from the closed position into the open position and vice versa. The locking member, which is e.g. constructed as a catch member, when the profile rail is pivoted into the open position and the seal is compressed, is disengaged from a slot or a locking strip on the furniture body in or behind which the locking member engages or locks in the closed position.
The open position of the profile rail is limited by at least one tilt stop. The tilt stop can e.g. be constructed on the locking member and can cooperate with an inside of the door, flap or drawer front panel. Alternatively or additionally a tilt stop can also be provided on the underside of the horizontal leg of the I or T-shaped profile rail and cooperates with an outside of the door, flap or front panel.
The closed position of the door, flap or drawer can additionally be secured by a retaining member. The retaining member can e.g. be provided in the area of the horizontal leg and preferably is vertically movable. In the closed position the retaining member can arrest the profile rail, in that it is held on an outside of the door, flap or drawer front panel. For opening the door, flap or drawer the retaining member is moved upwards, so that it projects over the horizontal profile rail leg and no longer impedes the pivoting of the profile rail into the open position. Advantageously the retaining member is constructed as a plug-in lock.
In the case of an alternative furniture closure, which is suitable both for a horizontal arrangement in an upper area of a flap or front panel of a drawer and for a vertical arrangement on a longitudinal side of a door, the profile rail is provided with a rotary inner tube to which is fastened the springy seal, the at least one locking member and the gripping strip. The profile rail is cross-sectionally roughly semicircular or also U-shaped with relatively short U-legs and is so placed on an insulating wall of a door, flap or front panel that the U-opening is directed towards the mating surface of the furniture item.
The springy seal is constructed as a cellular seal and is on the inside held, e.g. locked or clamped to the inner tube with an arcuate sealing foot.
The inner tube is constructed in complementary manner to the profile rail in circular form with a longitudinal slot in the vicinity of the profile rail U-opening and, roughly facing the springy seal, has a flattening for receiving at least one fastening member, e.g. a fastening screw, for retaining the gripping strip. In order to ensure the movability of the inner tube with springy seal, locking member and gripping strip, in the vicinity of the fastening screw the profile rail is provided with a recess, which is advantageously dimensioned in such a way that the opening movement of the locking member is limited. Simultaneously on the inside of the door, flap or front panel, which is appropriately constructed as an insulating wall, a stop is provided for the locking member.
For fastening to a marginal area of a door, flap or front panel the profile rail is equipped with fastening feet, which are constructed in complementary manner to a metal profile of the door, flap or front panel, so that the complete profile rail can be shoved in or locked. In the vicinity of the longitudinal slot the inner tube has outwardly directed legs, which cooperate with inwardly directed leg ends of the profile rail U-leg and ensure a reliable hold.
By means of a sealing head, which can e.g. have two hollow chambers, the springy seal engages on a furniture profile or a profile seal received therein and on a strip, which in a corner area of the furniture profile projects diagonally outwards and has a slot for the locking member. The furniture profile can e.g. roughly correspond to the extrusion profile for cooling cabinets and the like described in EP 213 310 B1.
The construction of the rigidly arranged profile rail with the rotary inner tube, e.g. made from extruded plastic, and springy seal, locking element and gripping strip fixed thereto is characterized by easy manufacture and particularly high sealing and insulating action, whilst simultaneously providing a secure closure and easy opening.
Particularly on placing a profile rail with springy seal, at least one locking member and a gripping strip in a partial area, e.g. on a longitudinal side of a door, it is advantageous to increase the spring tension of the springy seal by a seal extension. The seal extension is particularly appropriately provided outside the fastening area with which the seal is e.g. held in a fastening slot of the sealing profile.
The relatively short profile rail is then provided with end caps, which can be appropriately fixed in fastening points on the marginal area of the door or flap.
In an alternative construction of a furniture closure there is a profile rail with a springy seal, at least one closure member, a gripping strip and a longitudinal side pivot pin in a marginal area of a door, flap or front panel, in which a gripping recess is formed. Once again the springy seal is provided with a seal extension and the locking member has a hook-like construction and, in the closed position, engages behind a strip located on a furniture profile.
The invention is explained in greater detail hereinafter relative to the attached highly diagrammatic drawings, wherein show:
The profile rail 5 is located in the upper area of the front panel 3 and extends over the entire width.
To the profile rail 5 is fastened at least one locking member 7, which is constructed as a catch member and engages behind a wedge-shaped strip 14 in the area of the furniture item 11. The profile rail 5 also has a seal 6, which in this example is constructed as a lip seal and is anchored in an approximately T-shaped slot of the profile rail 5 and acts as a spring for the closure. The seal 6 extends over the entire width of the profile rail 5 and also ensures the necessary sealing on the longitudinal sides and the lower transverse side (not shown) of the front panel 3.
Below the locking member 7 and cooperating with an inside 16 of the front panel 3 is provided a tilt stop 31, which can e.g. be welded to the locking member 7. Alternatively a second tilt stop 37 is located on the underside of the horizontal leg 21 and for limiting the opening movement of the profile rail 5 strikes against an outside 17 of the front panel 3. The locking of locking member 7 behind the taper gib strip 14 takes place as a result of the spring tension of the seal 6 in the area of the profile rail 5.
In the variant of
Profile rail 5 is cross-sectionally approximately T-shaped and is movable fixed in the area of the contact surface 4 of the front panel 3 with a vertical leg 20. An almost horizontal leg is asymmetrically constructed and extends in an inclined outwards manner over the contact surface 4 or marginal area of the front panel 3 and passes terminally into a gripping strip 8.
The gripping strip 8 is angled and provided with a bead 25.
On the inside the horizontal leg 21 is shorter and is terminally provided with an angled fastening web or strut 22 for anchoring the seal 6. A further anchoring of the seal 6 on the terminal profile 5 takes place by means of a lower fastening strut or web 26 (
Seal 6 is made from an elastomeric, compressible material, so that according to arrow A in

The strip 14 is constructed as a taper gib strip and consequently ensures during the closing process a sliding movement of the locking member 7 or its hook 27 along the wedge surface until engagement takes place behind the strip 14 (
The variant of a furniture item 11 with opening 12 and drawer 2 received therein shown in
In addition, the profile rail 5 and locking member 7 form a unit. In the closed position shown in
Another variant of a furniture closure according to
In this variant the profile rail 5 is firmly fastened to the marginal area of door 41 or flap 3 and is constructed in roughly semicircular or U-shaped manner as a roughly horizontal U. The profile rail 5 is constructed for receiving a rotary inner tube 51 and the springy seal 6, the at least one locking member 7 and gripping strip 8 are fastened to the inner tube 51, which can be moved about the longitudinal axis 23, and with the inner tube 51 can pass from a closed position (
As a result of its construction as a cellular seal 60 with a sealing foot 61, which is held on the inside of the inner tube 51, and a sealing head 62 with two hollow chambers 63, 64 constructed for a flat engagement on the mating surface 13 of the furniture item 11, the springy seal 6 has a relatively high spring tension which effectively supports the closed and open position of the furniture closure.
In this embodiment the mating surface 13 of the furniture item 11 is formed by a furniture profile 42, which has chamber profiles 43, 44 at right angles to one another and an outwardly open corner area 45. The corner area 45 is constructed for receiving a profile seal 46 and for the engagement of the locking member 7 in the closed position. The springy seal 6 or cellular seal 60 of the profile rail 5 engages on the profile seal 46 and on a strip 14 of the furniture profile 42. The strip 14 is terminally positioned roughly diagonally in the corner area 45 and bounds a profile recess for the profile seal 46 and slot 15, in which engages the hook or nose 27 of the locking member 7.
The fixed U-shaped profile rail 5 is provided with relatively short U-legs 47, 48 and inwardly angled leg ends and is positioned horizontally with the U-opening pointing towards the mating surface 13. On the outside of the U-leg 47 are constructed in angular manner profile feet 49, 50 for fastening the profile rail 5 to the marginal area of the door, flap or front panel 3. The profile feet 49, 50 and the marginal area of the flap 3 or door 41 (
The inner tube 51, which in complementary manner to the U-opening of the profile rail 5 has a longitudinal opening, is provided with outwardly directed legs 52, 53, which cooperate with the leg ends of the profile rail 5. The inner tube 51 can consequently be slid into the profile rail 5, is securely retained and pivotable to a limited extent. The sealing foot 61 of springy seal 6 engages behind the longitudinal opening of the inner tube 51 and the sealing head 62 with the two hollow chambers 62, 64 projects outwardly and engages flat on the furniture profile 42 or profile seal 46.
Virtually facing the springy seal 6 the inner tube 51 has a fastening area for at least one fastening element 54, e.g. a fastening screw, with which the gripping strip 8 is held on the inner tube 51, which here has a flattened construction.
In the vicinity of the fastening screws 54 the profile rail 5 has in each case a recess 55 through which extends the fastening screw 54. The recess 55 can be dimensioned in such a way that the opening movement of the inner tube 51 with springy seal 6, locking member 7 and gripping strip 8 can be limited in predeterminable manner.
The at least one locking member 7 is fixed with the aid of fixing struts 56 in the inner tube 51 and an insulating material 57, which prevents cold spots, can additionally assist the secure retention of the locking member 7 and springy seal 6. Two protuberances 67 on inner tube 51 constructed in nipple form and which face one another, are used for arresting the locking member 7 on the inner tube 51.
