Description

[0001] Insertion chamber closure element and filter element

[0002] The invention relates to an insertion chamber closure element for covering a filter element insertion chamber formed by a filter element holding device and a filter element for insertion into a filter element insertion chamber formed by a filter element holding device.

[0003] Commercial vehicles typically have a filter element holder. This holder forms a filter element compartment. A filter element, such as a cabin air filter or an engine air filter, can be inserted into this compartment and usually has a predetermined service life. Once this service life has expired, the filter element should be replaced. Therefore, the holder usually has a compartment cover, in particular a cover, to close the compartment. When the filter element needs to be replaced after its service life, a cover is typically removed from a panel, revealing an access opening. The compartment cover is then detached from the holder and removed.The filter element is then removed from the filter element compartment. A new filter element is then inserted into the compartment, and the compartment closure element is reattached to the filter element holder and secured. Finally, the inspection cover is reinstalled. This procedure involves numerous individual steps, making the filter element replacement a complex process. Furthermore, the replacement can be complicated by the relatively small and therefore difficult-to-access mounting opening. Additionally, the filter element holder, and consequently the compartment closure element, may be located deep inside the vehicle and thus relatively far from the inspection cover, further complicating filter element replacement.From EP 1304244 B2, a filter element is known which consists of opposing frame sections connected by an additional frame section, thereby creating a space for the pleated filter element. The filter element projects beyond the side frame sections and has a sealing element made of soft material. The air filter system consists of a flexible top section that forms a seal when the cover is placed on top. The cover has locking hooks and reinforcing ribs that allow it to snap into the edge of the filter opening.

[0004] The invention is based on the objective of creating an insertion chamber closure element and a filter element, whereby the aforementioned disadvantages are reduced, or preferably do not occur.

[0005] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the preferred embodiments disclosed in the dependent claims and the description.

[0006] The problem is solved in particular by providing a compartment closure element, especially a compartment cover, for covering, and in particular closing, a filter element compartment formed by a filter element holding device. The compartment closure element comprises a base body and a filter element holding element. The base body has a longitudinal extension, in particular along a longitudinal direction, and a transverse extension that is shorter than the longitudinal extension and oriented transversely to the longitudinal extension, in particular along a transverse direction. The base body further comprises a first side and a second side, in particular opposite the first side. The filter element holding element is connected to the base body.The filter element retaining element is designed and configured to be detachably connected to a counter-filter element retaining element of a filter element arranged on the first side, in particular such that the filter element is attached to the filter element retaining element on the first side of the insertion chamber closure element by means of the counter-filter element retaining element.

[0007] Advantageously, the filter element, whose service life has expired, can be easily removed from the filter element compartment due to its attachment to the compartment closure element. Specifically, the worn filter element can be pulled out of the compartment using the compartment closure element. A new filter element can also be attached to the compartment closure element. The compartment closure element can then be placed onto the filter element holder, simultaneously inserting the attached filter element into the compartment. The new filter element can then be pushed into the compartment using the compartment closure element.

[0008] In particular, the longitudinal extent and the transverse extent define a basic body plane, wherein the first side is arranged on one side of the basic body plane, in particular of the basic body, and the second side is arranged on the other side of the basic body plane, in particular of the basic body.

[0009] In the context of this technical teaching, "removable" is to be understood in particular as non-destructively removable. Specifically, the counter-filter element retaining element can be connected to and detached from the filter element retaining element multiple times, especially many times, without destroying or impairing the filter element retaining element, in particular the base body, or the counter-filter element retaining element, in particular the filter element.

[0010] In one embodiment, the insertion chamber closure element has a circumferential sealing element. The sealing element is designed and configured to seal the filter element insertion chamber from the environment, particularly when the insertion chamber closure element is intended to be arranged on a filter element holding device.

[0011] In one embodiment, the insertion chamber closure element has a rectangular shape. In particular, the rectangular shape is defined by its longitudinal and transverse dimensions, and thus lies in the plane of the base body.

[0012] According to a further development of the invention, the insertion chamber closure element is provided to have two lever elements. The two lever elements are arranged on the second side and are each pivotably mounted on the base body between a mounting position and an operating position.

[0013] Advantageously, the two lever elements project from the base body in the mounting position, in particular such that they point towards the mounting opening when installed as intended. Specifically, the two lever elements extend through the mounting opening, allowing them to be gripped by a single person. This advantageously bridges the gap between the visible cover and the insertion chamber closure element, thus simplifying the replacement of the filter element, especially its removal and insertion.

[0014] In particular, the mounting position is a position into which the two lever elements are pivoted when a filter element is removed from or inserted into the filter element insertion space.

[0015] In particular, the operating position is a position to which the two lever elements are pivoted when a filter element is neither removed from nor inserted into the filter element insertion chamber. Specifically, the operating position is a position to which the two lever elements are pivoted when a commercial vehicle, in which the insertion chamber closure element is installed, is in operation, i.e., when it is not undergoing maintenance of the filter element.

[0016] In one embodiment – ​​when the counter-filter element retaining element of the filter element is connected to the filter element retaining element of the base body as intended and the lever elements are in the assembly position – the insertion chamber closure element can be placed on the filter element retaining device and the filter element insertion chamber can be closed, whereby, in particular simultaneously, the filter element is inserted into the filter element insertion chamber, especially because the filter element is connected to the insertion chamber closure element on its first side. In particular, the insertion chamber closure element can also be removed from the filter element retaining device and the filter element insertion chamber released, whereby, in particular simultaneously, the filter element is removed from the filter element insertion chamber, in particular pulled out.

[0017] According to a further development of the invention, it is provided that the two lever elements are pivotably mounted on the base body at opposite ends along the longitudinal extent.

[0018] Advantageously, the spaced arrangement of the two lever elements allows the insertion chamber closure element to be guided through the mounting opening with particular precision. In particular, tilting of the insertion chamber closure element is reduced, preferably avoided. Specifically, the pivot axes around which the two lever elements are pivotably mounted on the base body are oriented parallel to the transverse direction.

[0019] In one embodiment, the pivot axes are formed in that the two lever elements each have two, in particular, cylindrical projections, wherein the base body for the two lever elements each has two, in particular, cylindrical recesses into which the two projections engage. In particular, one, in particular, cylindrical projection engages in a, in particular, cylindrical recess. In particular, the two cylindrical projections are arranged opposite each other on the lever element in the depth direction of the lever element – ​​i.e., in the transverse direction of the base body, when installed as intended.

[0020] According to a further development of the invention, the two lever elements are each in contact with each other at a lever element contact area in the operating position. The lever element contact area is spaced apart from the base body along a vertical extension oriented transversely to the longitudinal and transverse extensions, in particular along a vertical direction.

[0021] Advantageously, the respective lever element assembly area is positioned between the filter housing closure element and the mounting opening when installed as intended. This lever element assembly area can be easily manipulated, particularly by a person, through the mounting opening. Specifically, the person can pivot the two lever elements from the operating position to the mounting position, allowing them to extend through the mounting opening. The filter element can then be easily removed from the filter element assembly chamber.

[0022] In particular, the respective lever element application area, especially a lever element application area plane in which the two lever elements abut each other, is oriented parallel to the flat base body, especially to the base body plane.

[0023] According to a further development of the invention, the two lever elements each have a first lever section and a second lever section. The first lever section is pivotably mounted on the base body. The first lever section is longer than the second lever section. The first lever section and the second lever section enclose a non-zero angle.

[0024] The design allows the two lever elements to be manipulated particularly easily by one person. In particular, the second lever section forms the lever element contact area.

[0025] In one embodiment, the first lever section and the second lever section enclose an angle that is less than 180°, in particular less than 170°, in particular less than 160°, in particular less than 150°, in particular less than 140°, in particular less than 130°, in particular less than 120°. In particular, the angle is greater than 90°, in particular greater than 100°, in particular greater than 110°.

[0026] In particular, the two angles of the two lever elements are open towards each other. Specifically, the openings of the two angles of the two lever elements are aligned towards each other, i.e., they point towards each other.

[0027] In particular, the base body and the two lever elements enclose a trapezoidal area in the operating position, and in particular, define this area, wherein the area is located in a plane defined by the longitudinal direction and by the vertical direction.

[0028] According to a further development of the invention, it is provided that the two lever elements each have an operating locking element which is designed and configured to interact with a counter-operating locking element of a filter element holding device in such a way that the insertion chamber closure element is locked in the operating position and that the insertion chamber closure element is released in the assembly position.

[0029] Advantageously, the insertion chamber closure element can be attached to or detached from the filter element holder by pivoting the two lever elements. When the two lever elements are pivoted into the mounting position by a person, so that they extend through the mounting opening, the insertion chamber closure element is simultaneously detached from the filter element holder, and in particular, unlocked, without requiring a separate release handle in addition to pivoting into the mounting position.Conversely, the insertion chamber closure element is attached to the filter element holding device, in particular locked to it, when the two lever elements are pivoted into the operating position by a person, in particular without the need for a separate fastening handle, in particular a locking handle, in addition to pivoting into the operating position.

[0030] In particular, the insertion chamber closure element is locked in such a way that it is attached to the filter element holding device. In particular, the insertion chamber closure element is released in such a way that it can be removed from the filter element holding device.

[0031] According to a further development of the invention, the filter element retaining element extends along the longitudinal direction and has at least two interlocking elements. The at least two interlocking elements each form an interlocking space, in particular a groove, with an interlocking space opening, in particular a groove opening. The at least two interlocking space openings are oriented towards or away from each other, in particular in pairs along the transverse direction. In particular, the at least two interlocking elements are designed and configured to each engage in a corresponding interlocking space of a corresponding filter element retaining element of a filter element.

[0032] Advantageously, this represents a particularly simple design, so that the insertion chamber closure element can be detachably connected to the filter element.

[0033] If the at least two recessed openings are aligned towards each other, each of the at least two recessed openings points – particularly along the transverse extent – ​​towards a transverse center of the base body. Specifically, each of the at least two recessed openings is open towards the transverse center.

[0034] If the at least two recessed openings are directed away from each other, they point, in particular, away from a transverse center of the base body along their transverse extent. Specifically, each of the at least two recessed openings is open away from the transverse center.

[0035] In one embodiment, the filter element retaining element is continuous along its longitudinal extent, thus having, in particular, exactly two interlocking elements. In another embodiment, the filter element retaining element is interrupted once or several times along its longitudinal extent, thus having, in particular, more than two interlocking elements.

[0036] According to a further development of the invention, the two lever elements each have a mounting locking element, wherein the two mounting locking elements form the filter element retaining element. The two mounting locking elements are each designed and configured to interact with a counter-mounting locking element of a filter element, and to secure the insertion chamber closure element to the filter element in the mounting position, and to release the filter element in the operating position.

[0037] The mounting locking elements offer the advantage that the insertion chamber closure element is only connected to, and specifically attached to, the filter element when the two lever elements are in the mounting position. Specifically, the insertion chamber closure element is not connected to, and specifically attached to, the filter element when the two lever elements are in the operating position.

[0038] According to a further development of the invention, it is provided that the two operating locking elements each have an operating engagement element, wherein the operating engagement element is designed and configured to engage in an operating engagement opening of the opposing operating locking element in the operating position, and in particular not to engage in the operating engagement opening in the assembly position.

[0039] Alternatively or additionally, it is provided that the two mounting locking elements each have a mounting engagement element, wherein the mounting engagement element is designed and configured to engage in a mounting engagement opening of the filter element in the mounting position, and in particular not to engage in the mounting engagement opening in the operating position.

[0040] In one embodiment, an engagement element, selected from the operating engagement element and the assembly engagement element, forms an engagement spring. In particular, an engagement opening, selected from the operating engagement opening and the assembly engagement opening, forms an engagement groove. Specifically, the engagement spring and the corresponding engagement groove are designed as a releasable tongue-and-groove connection. According to a further development of the invention, the two lever elements each comprise the operating engagement element and the assembly engagement element. The operating engagement element and the assembly engagement element are arranged, in particular along a longitudinal extent of the lever element, at the same end of the lever element.The operating engagement element and the assembly engagement element are arranged opposite each other at the same end of the lever element, particularly along a transverse extension oriented perpendicular to the longitudinal extension of the lever element.

[0041] Advantageously, a particularly positive-locking connection can be established between the insertion chamber closure element and the filter element by pivoting the two lever elements into the mounting position, whereby in particular a connection between the insertion chamber closure element and the filter element holding device is simultaneously released.

[0042] Conversely, a connection between the insertion chamber closure element and the filter element can be released by pivoting the two lever elements into the operating position, whereby in particular a positive-locking connection between the insertion chamber closure element and the filter element holding device is simultaneously established.

[0043] The problem is also solved by creating a filter element for insertion into a filter element insertion chamber formed by a filter element holding device. The filter element comprises a base body element and a counter-filter element holding element. The base body element has a functional section, in particular a filter section, which is specifically designed and configured to filter a fluid flowing through the filter section. The counter-filter element holding element is connected to the base body element, in particular attached to it.The counter-filter element retaining element is designed and configured to be detachably connected to a filter element retaining element of an insertion chamber closure element according to the invention or to an insertion chamber closure element according to one or more of the previously described embodiments, in particular such that the filter element is attached to the filter element retaining element on the first side of the insertion chamber closure element by means of the counter-filter element retaining element. In connection with the filter element, the advantages that have already been explained in connection with the insertion chamber closure element become particularly apparent. In one embodiment, the filter element is designed as an air filter element, in particular a cabin air filter or an engine air filter. In particular, the filter element is configured to be used as an air filter element in a commercial vehicle.

[0044] According to a further development of the invention, the base body element has a longitudinal extension, particularly along the longitudinal direction, and a transverse extension that is shorter than the longitudinal extension and oriented transversely to the longitudinal extension, particularly along the transverse direction. The counter-filter element holding element extends along the longitudinal extension and has at least two counter-engaging elements. The at least two counter-engaging elements each form a counter-engaging space with a counter-engaging space opening. The at least two counter-engaging space openings are oriented away from or towards each other, particularly in pairs along the transverse direction. In particular, the at least two counter-engaging elements are designed and configured to engage in one of the at least two engagement spaces of the filter element holding element of the insertion chamber closure element.

[0045] According to a further development of the invention, the base body element has a longitudinal extension, in particular along the longitudinal direction, and a transverse extension that is shorter than the longitudinal extension and oriented transversely to the longitudinal extension, in particular along the transverse direction. The base body element has two counter-mounting locking elements that form the counter-filter element retaining element. In particular, the two counter-mounting locking elements are arranged opposite each other along the longitudinal direction on the base body element.The two counter-mounting locking elements are designed and configured to cooperate with the two mounting locking elements of the insertion chamber closure element for the detachable fastening of the filter element to the insertion chamber closure element, in particular such that in the mounting position of the two lever elements the filter element with the two counter-mounting locking elements is fastened to the two mounting locking elements of the insertion chamber closure element, wherein in the operating position of the two lever elements the filter element with the two counter-mounting locking elements is not fastened to the two mounting locking elements of the insertion chamber closure element.

[0046] The problem is also solved by creating a commercial vehicle with an installation compartment closure element according to the invention, or an installation compartment closure element according to one or more of the embodiments described above, or a filter element according to the invention, or a filter element according to one or more of the embodiments described above. In connection with the commercial vehicle, the advantages that arise are particularly those already explained in connection with the installation compartment closure element and the filter element.

[0047] In one embodiment, the commercial vehicle has a filter element holder and a viewing panel in which the viewing panel cover can be inserted, and in particular is inserted. Specifically, the filter element holder and the viewing panel, and in particular the viewing panel cover, are spaced apart from each other when inserted. Specifically, the insertion compartment closure element is arranged in the commercial vehicle such that the two lever elements, in the installation position, extend through a mounting opening in the viewing panel. Specifically, in the operating position, the two lever elements do not extend through the mounting opening but rest against each other. Thus, in the operating position, the viewing panel cover can be inserted into the mounting opening and thereby closed.

Specifically, the insertion compartment closure element 1 is arranged in the commercial vehicle 51 such that the two lever elements 15, in the installation position (right-hand part of the figure), extend through a mounting opening 55 in the viewing panel 53. Specifically, in the operating position (left-hand part of the figure), the two lever elements 15 do not extend through the mounting opening 55 but lie against each other. Thus, in the operating position, the viewing panel cover can be inserted into the mounting opening 55 and thereby closed.
