Definitions
- the invention relates to a filter insert with a molded frame of a thermoplastic material.
- filter cartridges in which the filter element is encapsulated with a thermoplastic material.
- the filter material is thereby inserted into an injection mold, in such a way that its edge projects into a mold space of the injection mold and the remaining part of the filter material is arranged in a receiving space of the injection mold.
- By injecting the filter frame the edges of the filter material are incorporated into the plastic frame, thereby producing a tight bond between the frame and filter material.
- Such filter cartridges have the disadvantage that a separate cover for closing the insertion slot in a filter device is necessary.
- a filter insert for the equipment of a ventilation, heating and / or air conditioning in which the frame consists of a flexible and deformable thermoplastic elastomer and is attached to the filter medium by molding.
- this filter device has a transverse front surface which connects the side walls and is provided on the inside with a sealing means and on the outside with a gripping means.
- the transverse front surface serves as a cover for the insertion slot of the filter insert in a filter device.
- the known filter insert has the disadvantage that it requires a separate locking element.
- the object of the present invention has been made to provide a pleated filter insert with an injected frame made of a thermoplastic material, which eliminates the separate production of a lid for closing the insertion slot of the filter insert in a filter device and allows direct fixation of the filter cartridge in a filter device.
- the object is achieved by a generic type filter insert, in which on one of the end faces formed by a fold end of the filter insert made of a thermoplastic material, a lid is formed, which has two connected by film hinge pivot elements, wherein the film hinges approximately along the end edges of extend the pleat spanned spanned two planes and having at least one locking element on the pivot elements.
- the filter insert according to the invention makes it possible to dispense with a separately produced cover for the insertion slot of the filter insert into a filter device and secure the filter insert securely in the insertion slot by the integrally formed on the pivot elements locking elements and secure.
- the locking element is designed in the form of a Verrast ceremoniesslasche, which in a correspondingly shaped Receiving device engages the filter device housing and produces a secure locking in the form of a clip connection.
- the filter insert according to the invention preferably has sealing and / or positioning elements on the pivot elements, which ensure the correct installation of the filter element and the tight closure of the filter insert inserted into the filter device.
- the sealing element is designed in the form of a labyrinth seal.
- the filter insert according to the invention is produced in such a way that a pleated filter material is inserted into an injection molding device and at least one lid made of thermoplastic material is formed, in which connected with film hinges pivot elements approximately along the end edges, the plane spanned by filter backs extending planes and the at least one locking element exhibit.
- the invention further relates to a device for use in the inventive method, wherein the parting plane for the
- Fig. 1 is a perspective outside view of the invention
- Fig. 2 is a perspective view of the filter cartridge with a view of the inside of the lid.
- Fig. 1 shows a filter cartridge according to the invention with a circumferential
- Frame 1 made of a thermoplastic material, in which on one of the ends of the filter insert formed by a fold end, a lid 2 is formed, which has two hinged by film hinges 3, wherein the film hinge along the end edges of the spanned by the pleat spine two planes extend and wherein the pivot elements 3 have at least one locking element 4.
- Fig. 2 shows the perspective view of an inventive filter element with a view towards the inside of the molded onto the surrounding frame 1 cover 2.
- the associated with film hinges 5 pivot elements 3 of the lid 2 have locking elements 4.
- 3 sealing elements 6 are arranged in the form of a labyrinth seal on the inside of the pivot elements.
- the pivot elements 3 are pivoted from their production-related starting position after insertion of the filter insert according to the invention in a filter device by 90 ° in the direction of the frame 1 and the locking element 4 and the sealing elements 6 with correspondingly shaped engaging elements on the housing of the filter device into engagement brought.
- the filter insert according to the invention may further comprise integrally formed on the peripheral frame 1 sealing lips 7, which ensure the fluidically dense use of the filter element according to the invention in a filter device.
