Definitions
- the present invention relates to a filter housing for receiving at least one air filter element, in particular for a fresh air system of an internal combustion engine.
- the invention also relates to a method for producing such a filter housing.
- a filter housing usually consists of two shell bodies, which are usually made of plastic.
- the two shell bodies each have a flange and can be fastened to one another in the region of these flanges with the aid of fastening elements.
- screws can be used to screw the shell body together.
- Such fittings are usually made of metal and are subsequently attached to the shell bodies.
- the present invention deals with the problem of a filter housing or an associated manufacturing to provide an improved embodiment, which is characterized in particular by the fact that the cost of producing the filter housing is reduced, so that it is in particular cheaper to produce.
- the invention is based on the general idea of producing the respective shell body with the respective fastening elements together in a common mold by injection molding.
- the respective fastening elements are already on the shell body after the injection molding of the shell body, so that a separate mounting of the fastening elements on the shell body can be dispensed with.
- At least one of the fastening elements is designed as a tab which is arranged on one of the flanges and which cooperates for fastening the shell body together with a latching contour formed on the other flange, which then forms a complementary fastening element.
- the one shell body is then produced together with the at least one tab in a common mold by injection molding, while the other shell body together with the at least one locking contour in a common shape Injection molding is made.
- Such tabs, which cooperate with a latching contour are relatively easy to operate manually, whereby the filter housing can be opened and closed very easily.
- the at least one lug can be integrally formed on the respective shell body in such a way that it is elastically bendable to the extent that it can be latched to the respective latching contour.
- the desired bending elasticity can be realized for example by a correspondingly reduced material thickness in the region of the tab.
- a film hinge can be injected.
- the at least one tab may be provided to form the at least one tab on the shell body so that it is pivotally mounted in a fitting formed integrally on the respective shell body. It is basically possible to inject the tab during manufacture of the respective shell body so that it is first firmly connected to the fitting via at least one predetermined breaking point, said predetermined breaking point breaks the first pivoting adjustment of the tab.
- the tab can be injection molded at the same time that it forms a separate component with respect to the fitting from the beginning and is mounted pivotally adjustable in the fitting. The presented alternatives allow easy handling of the fasteners for opening and closing the filter housing.
- 1 is a sectional view of a filter housing in the region of a connection point
- FIG. 2 is a sectional perspective view of a shell body in the region of the connection point, but in another embodiment,
- FIG. 3 is a sectional view of the embodiment of FIG. 2,
- Fig. 4 is a perspective view of a shell body in the region of the connection point in a further embodiment
- Fig. 5 is a sectional view of the filter housing in another region of the connection point.
- a filter housing 1 comprises two shell bodies 2 and 3. In the assembled state, the two shell bodies 2, 3 enclose an interior space 4 for accommodating at least one air filter element (not shown).
- the filter housing 1 can be used for example in a fresh air system of an internal combustion engine, which may be arranged in particular in a motor vehicle. From the filter housing 1 only a small area is shown here, in which the two shell body 2, 3 are thus connected together in the assembled state when the housing 1 is closed. In this case, a joint designated below by 5 is defined.
- the flanges 6, 7 define the connection point 5.
- flanges 6, 7 engage each other in the manner of a tongue and groove connection.
- a sealing member 12 is additionally arranged in the tongue and groove connection of the flanges 6, 7 in order to improve the airtight connection of the two shell body 2, 3.
- the shell body 2, 3 are made of plastic, whereby the filter housing 1 is comparatively inexpensive to implement.
- the fastening elements 8 are made Made of plastic. In this case, the fastening elements 8 are produced together with the respective shell body 2, 3 in a common injection mold by injection molding.
- At least one of the fastening elements 8 designed as a tab or lever or bracket and is designated 9.
- Said tab 9 is configured or arranged on one of the flanges, here on the flange 7 of the upper shell body 3.
- the tab 9 cooperates with a complementary, designed as a locking contour 10 fastener 8, which is formed on the other flange 6 of the other shell body 2.
- the preparation of the two shell body 2, 3 expediently so that the one shell body 3 is made together with the at least one tab 9 in a common mold by injection molding.
- the other shell body 2 is produced together with at least one locking contour 10 in a common shape by injection molding.
- Fig. 1 shows an embodiment in which the at least one tab 9 is integrally formed on the respective shell body 3.
- this tab 9 is designed so that it is elastically bendable. In particular, it may be elastically flexible so far that it can be latched to the respective locking contour 10.
- 1 shows the tab 9 with a solid line in the locked state and with a broken line in a relaxed starting position. Status.
- a double arrow 11 indicates the bending elastic deformability of the tab 9.
- the tab 9 is bent over for transferring into the locked state by approximately 90 °.
- the state shown can also be the undeformed state, so that the tab 9 must be temporarily bent open for latching and unlatching.
- the respective tab 9 has a detent opening 13, in which a detent
- FIGS. 2 and 3 show another embodiment in which the respective tab 9 is pivotally mounted in a fitting 15 about a pivot axis 16.
- the respective fitting 15 is integrally formed on the respective shell body 2.
- the tab 9 is injection-molded during the manufacture of the respective shell body 2 so that it subsequently engages with the fitting 15 is fixedly connected via a symbolically indicated in Fig. 3 by a point predetermined breaking point.
- This predetermined breaking point 17 can be broken at the first pivoting adjustment of the tab 9, whereby the tab 9 separated from the shell body 2 and the free Schwenkversteiliana the tab 9 is realized.
- the formation of such a predetermined breaking point 17 can simplify the production of the common shape of shell body 2 and tab 9.
- Fig. 3 is a possible introduction of force to break loose the tab 9 indicated by arrows 21.
- the swivel adjustability is again indicated by a double arrow 11.
- Another, shown with a broken line arrow 22 symbolizes the resilient operation of the spring portion 18 at its extension or extension 19th
- the tab 9 is spray-formed on the respective shell body 3 so that it forms a separate component from the beginning, which is already mounted pivotally adjustable in the fitting 15.
- the tab 9 is shaped and injection molded so that it is arranged captive in the fitting by 15 by positive engagement.
- a spring portion 18 is formed on the tab 9, which can engage behind the complementary thereto designed locking contour 10 form fit on the other flange.
- An extension 19 of this spring portion 18 simplifies the opening and closing or the engagement and disengagement of the tab 9, which simplifies the handling of the fasteners 8.
- At least one of the fastening elements 8 can be designed as a hinge 20.
- This hinge 20 is integrally formed on both shell bodies 2, 3 and allows pivoting of the two shell body 2, 3 relative to each other, so as to open and close the filter housing 1 can.
- the hinge 20 is formed by a correspondingly flexurally elastic web-shaped section, which has, for example, a reduced wall thickness.
- the hinge 20 may be a living hinge.
- a hinge 20 or such hinges 20 are arranged or formed only on one side of the filter housing 1 in order to be able to pivot the two shell bodies 2, 3 about a pivot axis extending along this housing side.
- At least one of the three other housing sides may then comprise at least one of the pairs of cooperating fasteners 8, e.g. a tab 9 and a locking contour 10th
- both shell body 2, 3 can be injection molded with all fasteners 8 in a common shape, whereby the manufacturing cost can be further reduced.
