The present invention relates to a box washer for receiving articles, in particular for receiving and washing storage boxes, according to the preamble of patent claim 1 and a door lock according to the preamble of patent claim 10.

In addition, such a crate washer comprises a housing for accommodating the articles, wherein the articles can be introduced into the housing via at least one housing opening of the housing, and a door pivotable about a pivot axis, preferably in the horizontal or in the vertical direction, for closing a housing opening. In particular, the housing opening may also be a side opening of the housing. This is then intended to visually control the washing process, for example, and / or make these maintenance in the crate washer.

In particular, such a side opening is not that opening through which the articles to be washed are introduced into the housing, as part of a regular cleaning procedure. It should be noted that these side openings may also be suitable for removing articles from the housing for maintenance purposes (eg wedged articles).

In this case, at least one door lock, which is operable in an open mode and in an on-mode, of the box washer comprises, wherein in an open mode, the door about the pivot axis is pivotable, and about a pivotal movement of the door, the housing opening through the door can be opened and / or closed, and in the closed mode, the door mechanically closes the housing opening.

However, such prior art box washers are well known in the art. In principle, a crate washer for mechanically fixed, preferably watertight closing a housing opening of the housing, corresponding door locks that prevent the door unintentionally, for example, during a washing or cleaning operation of the storage box opens or a seal between the door and the housing wall no longer waterproof closes.

However, known from the prior art door locks for such a box washer are designed to be less robust and / or relatively fine mechanical, so there is the danger in door locks known from the prior art after frequent use that the door lock has at least signs of wear.

It is therefore an object of the present invention to provide a crate washer for accommodating articles, in particular for receiving and washing storage boxes, which makes it possible in a particularly simple and cost-effective manner to provide a door lock, which is particularly stable in operation.

This object is solved by the subject matter of patent claim 1.

In order to provide a box washer for receiving articles, in particular for receiving and washing storage boxes, in which a door lock is designed to be operationally stable in a particularly cost-effective manner, the present invention makes use, inter alia, of the idea that the door lock at least one, in particular on the outside of the housing, fixed fixing element and at least one lever element which is parallel to the pivot axis, in the vertical direction or in the horizontal direction, pivotally mounted, in particular on the door, wherein via a pivoting movement of the lever member, the door lock of the open mode in can be brought to the mode and vice versa, and wherein the fixing member has an engagement portion for locking with the lever member, wherein in the locked state, the door lock is operated in the on mode. Alternatively, the fixing element also inside be mounted on an inner surface of the housing. "Vertical direction" describes a direction parallel to the direction of the gravitational force. The vertical direction thus runs perpendicular to the earth's surface. Accordingly, a "horizontal direction" runs parallel to the earth's surface

In particular, the pivoting movement of the lever element described here and the possible latching of the lever element with an engagement region of the fixing element allow a completely mechanical and operationally stable locking and unlocking of the entire door. The lever movement is here namely formed by a lever axis about which the lever member is pivotally mounted, so that can be dispensed with additional mechanical components of a previously known much more complex door lock, which makes the entire component and in particular the door lock particularly stable in operation and wear.

In accordance with at least one embodiment, the box washer for receiving articles, in particular for receiving and washing storage boxes, comprises a housing for receiving the articles, wherein the articles can be introduced into the housing via at least one housing opening of the housing. Furthermore, the crate washer comprises at least one pivotable about a pivot axis in the horizontal direction door for closing a housing opening and at least one door lock, which is preferably a door uniquely, for example, unique, operable and operable in an open mode and in an on-mode, wherein in an open mode, the door is pivotable about the pivot axis and the housing opening through the door can be opened and / or closed via a pivoting movement of the door, and in the closed mode, the door closes the housing opening firmly. In this case, the door lock comprises at least one, in particular outside of the housing, fixed fixing element and at least one lever element, which is parallel to the pivot axis, in the vertical direction or in the horizontal direction, pivotally mounted, in particular on the door, wherein via a pivoting movement of the lever member, the door lock can be brought from the open mode to the on-mode and vice versa, and wherein the fixing member has an engagement portion for locking with the lever member, wherein in the locked state, the door lock is operated in the on mode.

In accordance with at least one embodiment, the lever element is arranged such that it can pivot about a lever axis fastened to a door side surface, wherein the lever arm element comprises at least one engagement element which is arranged engageable in the fixing element such that the engagement element can be latched to the fixing element via a lever movement. In this case, a door side surface is the surface which connects the two large cover surfaces of a door with each other. A Hauterstreckungsebene the door side surfaces extends in the mounted state of the door on the housing parallel to the vertical direction. In other words, the lever element is thus arranged laterally or on the sides of the door. Alternatively or additionally, the lever element can be pivotably arranged about another side surface, for example, on the side surface of a window of the door, pivotally.

In accordance with at least one embodiment, the lever movement can be initiated by engagement with an actuating lever arm lying opposite the engagement lever arm, and the engagement element can be released and / or latched by the fixing element via a lifting movement. Preferably, therefore, the Eingriffshebelarm and the Betätigungshebelarm form portions of the entire Hebelelementarms and / or the entire lever element. Preferably, the Eingriffshebelarm and the Betätigungshebelarm are therefore formed integrally with each other. In other words, the Betätigungshebelarm can be actuated by a user and, for example, be depressed, which moves by pushing down the Eingriffshebelarm correspondingly up or one end of the Eingriffshebelarms moves relative to the lever axis upwards, and by such upward movement of the Eingriffshebelarm dissolves from a fixation and locking with the fixing. The same applies to a downward movement. For then only the lever element and the fixing element have to be configured in such a way that the end of the Eingriffshebelarms moves downward by a lever movement and in particular an actuation of the lever arm by pulling the user upwards and thereby vonstattengeht a detaching movement of the fixing.

In accordance with at least one embodiment, the fixing element comprises a mounting region for mechanically fixed mounting on the outer surface of the housing and a fixing region, preferably raised from the outer surface and spaced from the outer surface, wherein the engagement element can be latched to the fixing region and in the locked state State in the horizontal direction, the engagement element between the fixing region and the outer surface of the housing is arranged. Preferably, the mounting area and the fixing area are integrally formed with each other. It is conceivable in this context that between the fixing region and the mounting region, a transition region is formed, which has at least one transition bend, for example in the direction or away, from the outer surface of the housing. Also in such an embodiment, preferably, the fixing region, the transition region and the mounting region are formed integrally with each other. If the engagement element is locked to the fixing region, and therefore arranged between the fixing region and the outer surface of the housing, this is therefore clamped between the outer surface of the housing and the fixing region of the fixing element.

In accordance with at least one embodiment, the fixing region comprises at least one fixing curvature, wherein in the locked state the engagement element is mounted within the fixing curvature, in particular between the fixing curvature and an outer surface of the housing, and wherein the fixing curvature is curved away relative to the outer surface of the housing. In this respect, the Fixierkrümmung forms viewed from the outside an inverted curvature belly. In fact, it is advantageously made possible for a free end of the engagement lever arm, which is to be engaged with the fixing region and the fixing curvature, to close the door, being moved rotationally out of the fixing curvature (rotating about the lever axis) via the pivoting movement. The Fixierkrümmung therefore limited in the locked state of the door lock movement of the end of the Eingriffshebelarms and thus prevents movement of the Eingriffshebelarms and in the horizontal and vertical direction.

In particular, it is conceivable that the fixing curvature is part of an S-shaped fixing region, wherein an upper abdominal region of such an S-shaped fixing region represents the fixing curvature and a lower lower abdominal region S-shaped fixing region is curved away from the outer surface of the housing.

In accordance with at least one embodiment, the engagement element is designed in the form of an engagement pin whose main extension direction is parallel to the lever axis of the lever and / or parallel to the horizontal direction. Preferably, such an engagement pin is fixedly connected to one end of the Eingriffshebelarms. Such a design the engagement lever element in the form of an engagement pin represents a particularly stable and mechanically simple embodiment of the engagement element, since it is possible to dispense with a multiplicity of elements, for example mechanically interconnected to one another. The engagement pin is therefore arranged in the locked state between the outer surface of the housing and the fixing region, in particular between the outer surface of the housing and the fixing curvature of the fixing region.

In accordance with at least one embodiment, the crate washer comprises at least two door locks according to at least one of the preceding embodiments, wherein the door locks are vertically spaced and superimposed and interconnected and synchronized by an actuating rod. In other words, the actuating rod connects ends of the individual actuating lever arms of the individual door locks with each other so that both door locks can be opened or closed simultaneously. The actuating rod is then arranged parallel to the vertical direction. It is also conceivable that a plurality of door locks is arranged on the actuating rod and thus the actuating rod is connected to the corresponding actuating lever arms. Such a configuration and arrangement of the door lock to each other via the actuating rod is also referred to as a vertical arrangement of the door lock.

In accordance with at least one embodiment, the box washer comprises at least two door locks according to at least one previous embodiment, wherein the door lock arranged in the horizontal direction next to each other and spaced apart via an actuating rod and are synchronized by this circuit. The actuating rod is therefore arranged parallel to the horizontal direction. Such a horizontal arrangement therefore describes an above vertical arrangement alternative embodiment of the interconnection of the individual door locks on the actuating rod.

In accordance with at least one embodiment, the fixing region comprises an intermediate region which connects the mounting region of the fixing element to the fixing curvature, wherein the intermediate region extends at least locally rectilinearly away from the outer surface of the housing at a predeterminable spraying angle.

In addition, the application relates to a door lock as described for example in one of the abovementioned embodiments of the box washer described above. That is, the features disclosed for the box washer described herein (particularly in connection with the door lock described therein) are also disclosed for the door lock described below, and vice versa.

In accordance with at least one embodiment, the door lock for locking a housing comprises at least one fixing element fastened on the outside of the housing and at least one lever element, which is pivotable in the direction parallel to a pivot axis of a door of the housing, in particular in the vertical direction or in the horizontal direction, in particular on the door , can be brought, wherein via a pivoting movement of the lever member, the door lock can be brought from an open mode in an on-mode and vice versa, and wherein the fixing element has an engagement region for locking with the lever element, wherein in the locked state, the door lock in the locked Mode is operated.

In the Fig. 1A It can be seen that on a outer surface 21 of a housing 2, a fixing element 41 via two fastening bolts and / or fixing screws S1, S2 is mechanically fixed to the outer surface 21 of the housing 2. The fixing element 41 is part of a door lock 4. In particular, the fixing element comprises a mounting portion 410 which is mechanically arranged on the outer surface 21 of the housing 2 via the fastening screws S1, S2 and a raised from the outer surface 21 of the housing 2 and spaced from the Outer surface 21 of the housing 2 extending fixing region 420, wherein the mounting portion 410 and the fixing portion 420 of the fixing member 41 are connected to each other via an intermediate portion 430. The mounting region 410 and the fixing region 420 are preferably statically arranged in a mechanically fixed connection relative to one another via the intermediate region 430.

In particular, the fixing region 420 comprises at least one fixing curvature 420 B, which is curved out relative to the outer surface 21 from the outside to the outer surface 21 of the housing 2.

On a door side surface 33 of a door 3, a fixing plate is arranged on the door side surface 33 via further mechanical fastening screws S3 and S4, wherein a lever axis H is formed and fixed by the door side surface 33 and in particular by the door side plate. In this respect, a lever member 42 of the door latch 4 is pivotally rotatable about the lever axis H1 in the vertical direction V.

In addition, it is shown that the lever member 42 is formed with an Eingriffshebelarm 42 A and a Betätigungshebelarm 42 B, wherein both lever arms 42 A and 42 B in one piece are formed with each other and therefore form the lever element 42 as a whole. At an open end of the operating lever arm 42B, there is disposed an operating rod 9 through which an operator of the lever member 42 can pivotally rotate about the lever axis H.

One of the gist of the invention is that a free end of the engagement lever arm 42A comprises an engagement element 420A, this engagement element 420A being in the form of an engagement peg whose main extension direction is parallel to the lever axis H1 of the lever element 42 and parallel to the horizontal direction H.

How particularly catchy from the Fig. 1A can be recognized, therefore, the engagement member 420 is clamped between the outer surface 21 of the housing 2 and a Fixierkrümmung 420B in the region of the fixing portion 420. Thus, the door 3 is locked to the housing 2 and closes a housing opening 21 of the housing 2 completely.

In contrast, in the Fig. 1B in the schematic side view of the there described and shown door lock 4 shown in an open state, it can be seen that the actuating rod 9 was pressed in the upward direction, which immediately led to the Eingriffshebelarm 42 A, in particular its end with the engagement pin in a rotational movement was rotationally moved out of the Fixierkrümmung 420B, so that in the opening direction 500 of an open-movement of the door 3, the fixing element 41 is no longer in the way. The door 3 is therefore freely movable and can be brought from a closed state, that is from an on position, into an open position.

The Fig. 2 shows the in the Fig. 1A Door lock 4 and the housing 2 shown there in a lateral perspective view. It is particularly easy to see from this schematic perspective view that the actuating rod 9 is arranged parallel to the horizontal direction H and in this direction, the two lever members 42 connects to each other and is arranged at the ends of the Betätigungshebelarme 42 B of the two lever members 42.

In the Fig. 3A to 6 In comparison, a vertical arrangement of the actuating rod 9 is shown, so that the actuating rod 9, the two door locks 4 in the vertical direction V together, the opening principle is the same as in connection with the Fig. 1A to 3 shown. In the Figures 5 and 6 is the installation variant according to FIG. 4 shown.

In Fig. 7 is a schematic front view of an embodiment of a box washer 1 described here, comprising the housing 2 described here for receiving articles, in particular for receiving and washing storage boxes shown. It can be recognized particularly simply that each of the doors 3, which represent side doors, for example for the maintenance of the box washer 1, are pivotable about a pivot axis 32 in the horizontal direction H and the housing opening 21, which is a side opening, is opened and closed via the pivoting movement can. In particular, the side opening shown here is not the opening through which the articles to be washed are introduced into the housing 2 in the regular washing operation. It should therefore be mentioned that these side openings may also be suitable for removing articles from the housing 2 for maintenance purposes (eg wedged articles). Insofar is in the FIG. 6 in the FIGS. 3A to 5 shown box washer 1 shown in a schematic perspective overall view.

The invention is not limited by the description and the embodiments. Rather, the invention includes any novel feature as well as any combination of features, including in particular any combination of features in the claims, even if this feature or combination itself is not explicitly stated in the claims or in the embodiments.
