Description

The invention relates to a fitting for a drawer module of a mobile vehicle, in particular a motorhome, a caravan or a boat.

In mobile vehicles are often housed interior fittings in which items can be stored. For example, in the mobile vehicle, a drawer module may be installed in a furniture carcass. Several drawers are arranged one above the other in the furniture body. A conventional drawer module in the kitchen area of a caravan usually has three drawers arranged one above the other. To prevent these drawers from unintentionally opening while driving, they can be secured individually with locking elements. For this purpose hook hooks are often used, which can be unlocked from the front panel of the respective drawer ago. To open the drawer, the lock must be unlocked each time. However, it is desirable that when the vehicle is stationary, the drawers, as a user usual kitchen is easy to raise. If the drawers must be locked in preparation for the departure of the vehicle, so this should also be easy to carry out. When driving, it must be ensured that the drawers do not accidentally come loose, especially in the case of strong vibrations and cornering.

Generic fittings are made, for example US Pat. No. 6,722,167 B or GB 191212591 A known.

It is an object of the invention to provide a fitting for a drawer module of a mobile vehicle, in which the ease of use is significantly improved. This object is achieved with a fitting according to claim 1. Accordingly, a fitting with a blocking element is proposed, which has locking members according to the number of drawers to be locked, wherein by means of an actuating element a trigger is adjustable, which acts on a switching piece with the locking element at least two of the locking parts, preferably all locking parts between a locking and an open position to adjust. In this case, the trigger is coupled to a control unit and can be locked by means of a push-latch mechanism in the locking position of the blocking element associated switching position.

Push-latch mechanisms are known from the prior art and are widely used for furniture closures. Such closures are also known by the term push-to-open mechanisms. In this case, a control panel is manually pressed into an overstroke position in the closure of the closure. As a result of this overstroke the locking position of the control panel is canceled. After unloading the control panel pushes a spring the control panel in an open position. At the same time a locking member, such as a locking hook is moved to the open position with the control panel. If the closure is to be brought back into its closing position, pressure is applied manually to the operating element, so that the latter is pushed into the closed position. In the Closed position is again a locking of the control. The locking of the control element is achieved with an overstroke mechanism, as used in ballpoint pens. This ballpoint pen mechanism has a locking cam which cooperates with a control cam. In the closed position of the locking cam is locked in the control cam. After applying the overstroke, the locking cam is disengaged from the control cam and the operating element (ballpoint button) is moved to the open position.

The inventor has now recognized that such a push-latch mechanism is particularly suitable for use in a fitting for a drawer module of a mobile vehicle. A trigger is coupled to the push-latch mechanism which acts on a switching piece of the blocking element. Thus, the locking parts can be adjusted between a locked and an open position. For example, upon engagement of the trigger on the switching piece, the blocking element can be offset so that the locking parts reach their blocking position and then block the drawers. With the push-latch mechanism and the locking elements coupled to the locking elements can thus simultaneously lock or unlock several drawers with a push of a button. This significantly increases the ease of use. In addition, a secure determination of the drawers is thus achieved in a simple manner, which is also sufficiently stable to vibration to prevent accidental opening of the drawers. According to the invention, the trigger is coupled to an actuating part, which is adjustable in a housing by means of the operating part, and that the actuating part and the housing form a switching cam and a cooperating switching curve of the push-latch mechanism. In this way, a simple construction becomes possible.

In order to ensure a secure locking and operation of the push-latch mechanism, it may be provided that the actuating element has a spring which holds the control part spring biased.

In order to achieve a natural closing movement for the purpose of high operating comfort, it can be provided that the setting part is linearly adjustable by means of the operating part. For example, the linear adjustment can then run in the direction of the depth of the drawer. If the control panel is then attached to the front panel of the drawer, so a user can simultaneously make a convenient lock with the closing of the drawer. According to the switching piece on a casserole curve on which the shutter runs during the adjustment runs to move the contact piece from a blocking in an open position. This results in low parts and assembly costs a reliable working design. A particularly preferred variant of the invention is such that the trigger is guided at least over a partial region of its adjustment path between the contact piece and a support section. As a result, a sufficiently vibration-resistant fitting design is possible. To reduce the parts expenditure, it can also be provided that the support portion is part of a fastening part for fastening the blocking element to a furniture body.

A simple assembly is possible when it is provided that the position assignment of the support section to the trigger by means of an adjustment section, in particular a long hole is changeable.

For this purpose it can also be provided that at least a part of the locking parts adjustable, in particular infinitely adjustable fastened to the locking element are. The locking parts can then be individually adjusted to different drawer sizes.

It may happen that the fitting was accidentally brought into the locking position and some of the drawers were already locked, with one or more drawers are still in the open position. In order to take account of such an application, it may be provided that at least one of the locking parts has a deflection portion to allow a deflection movement of the locking element or the locking piece in cooperation with a blocking piece of the drawer. If now this open drawer is moved into the closed position, the blocking piece acts on the deflection section and adjusts the locking element and / or the locking piece such that the drawer can move unhindered into the closed position.

FIG. 1 shows a furniture M with a drawer module housed therein, which has three drawers S. The drawers S are attached with conventional pullout guides on the furniture body of the furniture M and can be in the image plane according to Fig. 1 pull out horizontally to the left.

The drawers S are constructed in a known manner. They have two drawer 15 extending in the depth direction of the drawer. At the longitudinal ends of the drawer 15 is a front panel 11 and the rear side coupled to a rear wall. Bottom side, the drawer is closed with a bottom 16. The drawer hinges 15 may be equipped as double wall frames of known type. On the front panel 11, a handle 12 may be mounted. As the Fig. 2 to 4 show, in the top drawer S of the drawer module a bore 13 is inserted into the front panel 11. In the bore 13, a rosette 14 can be used from the front side of the front panel 11 ago. The rosette 14 surrounds a receiving area in which a control unit 21 of an actuating element 20 is arranged. With the control panel 21, a control part 22 is coupled. For this purpose, the adjusting part 22 on a thread 22.1, which is screwed into a thread of the control unit 21. The adjusting member 22 has at the end facing away from the thread 22.1 a trigger 22.2, which is formed in a pin-shaped and is completed with a cap-like rounding section, as this Fig. 4 clearly recognizable. In the area between the thread 22.1 and the trigger 22.2, the control part 22 has a switching section 22.3 with a switching cam 22.5. The switching cam 22.5 is integrally formed on the actuating part 22. Towards the trigger 22.2, a stop 22.4 is arranged at a distance from the switching cam 22.5. The adjusting part 22 can be inserted into a housing 24. The housing has a bottom 24.1, from which revolves a housing wall 24.2 rises. The housing wall 24.2 is in the switching cam 22.5 facing region formed with a switching curve 24.3 to form the push-latch mechanism. The housing 24 has the front panel 11 facing a flange 24.4. About the housing 24, a carrier 25 is pushed. This has a breakthrough, which receives the housing 24 in the region of the flange 24.4. The carrier 25 has a receptacle for the flange 24.4, which is received in a form-fitting manner therein in the direction of the central longitudinal axis of the actuating element 20. The carrier 25 has a flange 25.1 with screw receptacles. The carrier 25 can be set via a fastening part 26, wherein the flange 25.1 comes to rest on a flange 26.1 of the fastening part 26. The flange 26.1 has screw receptacles, which are arranged in alignment with the screw receptacles of the flange 25.1. By the escaping screw mounts a screw 27 can be passed and screwed back into the front panel 11. Thus, the control element 20 is then securely attached to the front panel 11. In order to achieve an exact alignment of the actuating element 20 relative to the front panel 11, the fastening part 26 has a centering projection 26. 2, which is aligned in the bore 13. As Fig. 4 can be further seen, in the region of the bottom 24.1 of the housing 24, a spring 23 in the space between the housing wall 24.2 and the adjusting member 22 is arranged.

As Fig. 1 can be seen, a blocking element 30 is disposed on a wall of the furniture body. In this case, the blocking element 30 extends laterally of the drawers S, as this Fig. 2 lets recognize. The blocking element 30 is formed by a profile section, in the present case a C-profile. The blocking element 30 can be connected by means of fastening parts 33 with the body wall. As Fig. 3 can be seen, the fastening part 31.1 on two lateral lugs, the support portions 33.3 form. Between the support sections 33.3 extends a cover section which engages over the blocking element 30. The fastening part 33 is equipped with two oblong holes 33.1, can be passed through the screws 33.2 and screwed into the furniture carcass wall. The fasteners 33 allow adjustment of the Locking element 30 in the direction of its central longitudinal axis. Accordingly, the locking member 30 can be adjusted in the vertical direction. The blocking element 30 has a longitudinal slot 31 and, since it is designed as a C-profile, receive sliding blocks. At the upper longitudinal end of the blocking element can be coupled with such a sliding block, a contact piece 32. For this purpose, a screw 32.1 is inserted through a screw of the contact piece 32 and screwed into the nut located in the locking element. The switching piece 32 has a switching element 32.2, which is formed in the form of a beveled runner runner. As Fig. 3 can recognize, with the locking element 30 locking members 34 continue to be screwed on nuts (fixing screw 34.1). For each drawer, a locking part 34 is provided, as this Fig. 1 lets recognize. The locking parts 34 have a guide 34.2, in the guideway of a locking piece 34.4 is housed. On the left side, the locking piece 34.4 has a deflection slope 34.3 and opposite a blocking portion 34.5. The locking member 34 cooperates with a blocking piece 17.1, which is arranged on the drawer side. The blocking piece 17.1 may be part of a holder 17, which is attached to the bottom 16 of the drawer S.

In the following, the operation of the arrangement shown in the drawings will be explained. As Fig. 1 shows, all drawers S can be spent in furniture M in the closed position. In this case, the trigger 22 engages under the switching piece 32 and is simultaneously supported on the support portion 23.3 of the fixing part 33, as this Fig. 3 shows. The blocking element 30 is in the blocking position. Accordingly, the blocking pieces 17.1 of the drawers S are blocked at the locking portions 34.5 of the locking parts 34. This prevents that the drawer S can be pulled into the open position. If the drawers S should now be opened, then an overstroke is applied to the operating part 21. Accordingly, the operating part 21 is pressed, so that there is a small displacement, starting from the position according to Fig. 3 to the right. Because of this Overstroke slides the switching cam 22.5 in the switching curve 34.3 and is brought into a switching position in which the switching cam 22.5 is out of engagement with the switching curve 24.3. Now, if the control unit 21 is relieved, the biased spring 23 pushes the control part 22 in the image plane according to Fig. 4 to the left. Thus, the fixed to the control part 22 coupled control panel 21 is shifted to the left. Fig. 5 shows the Ausschubstellung the control panel 21, the Ausschubbewegung is limited by a stop 22.6 of the control panel 22, which abuts against a counter-stop 24.5 of the housing 24. As Fig. 5 can be seen, passes during the adjustment of the actuator 22 of the trigger 22.2 out of engagement with the contact piece 32. Thus, the locking element 30 is released continuously and it can move vertically downward due to the applied gravity. With the displacement of the blocking element 30 and the locking parts 34 are adjusted in the direction of gravity. The blocking pieces get 17.1 out of engagement with the locking portions 34.5, as this Fig. 5 shows. The drawers S can now be pulled freely into the open position. After use, the drawers can then be pushed back into the closed position, which in Fig. 5 is shown.

If now the drawers S are to be locked, then the control panel 21, starting from the operating position according to Fig. 5 , pressed. Thus, the adjusting member 22 moves in the housing 24 under tension of the spring 23 in the image plane according to Fig. 5 to the right. In this case, the trigger 22.2 meets the trained as a runner switching element 32.2. Then the trigger slides 22.2 on the runner 23.2 and moves the locking element 30 against the direction of gravity. Accordingly, the locking parts 34 are raised so that the blocking pieces 17.1 are locked to the locking portions 34.5. If the operating element 21 is then relieved after it has been completely inserted, the switching cam 22.5 is locked in a blocked region of the skid 24.3, so that the in Fig. 3 shown operating position is present again.

Now it may happen that the control panel 21 is in its depressed position; Consequently, the shutter 22.2 is extended to the rear, although the drawer S is not yet in the closed position, as this Fig. 5 shows. When the drawer S is now closed, the trigger 22.2 hits the contact piece 32, whereby the blocking element 30 is moved vertically upwards. The associated blocking piece 17.1 of the upper drawer S then enters the area of the deflection slope 34.3 of the guide 34.2 and then properly bypasses the locking piece 34.4 until it comes to rest in the area of the blocking portion 34.5 when the drawer S is completely closed.

Furthermore, an application is now conceivable in which all but one drawer S are closed. As Fig. 6 If this is the case, if the upper drawer S is closed, the drawer S underneath is still open. In such a case, the illustrated construction allows easy closing of the still open drawer. The associated locking piece 34 of the drawer is already in the closed position. If now this drawer S is closed, the blocking piece 17.1 hits the associated deflection slope 34.3 of the locking piece 34.4. As a result, the locking part 34 and with it the locking element 30 is raised against the direction of gravity. The blocking piece 17.1 bypasses the locking piece 34.4 until it then comes to rest in the region of the blocking portion 34.5. Then then the blocking element 30 falls under gravity back into the in Fig. 3 shown position and all drawers S are locked correctly.
