Definitions
- This invention relates to an improved cover, which may be utilized for an air filter to provide a resilient snap fit.
- air filters are utilized to filter the air passing from a source of air to a vehicle engine.
- the air filter is captured between an upper cover and a lower cover.
- the two covers are secured together in some fashion.
- wing bolts having threaded nuts secured onto the bolts hold the two cover portions together.
- the vehicle engine is subject to a good deal of vibration.
- the wing nut connection has not always provided a good connection over time.
- it is relatively time consuming to remove the nut and then resecure the nut.
- an air cleaner upper cover is secured to a lower cover by a snap fit connection.
- the snap fit connection includes at least one wing member having a wedged surface, which extends through a wedged surface slot in the other cover member.
- the two cover members are aligned with the slot in the one cover member aligned with the wedged wing surface. As the wing surface moves through the slot, the two wedges on the slot and the wing cam the wing away from the slot wedge surface. Once the wing portion has moved through the slot, the wing twists back over the surface adjacent the slot.
- the wing portion is provided on a post, and the post extends through the slot after the wing has moved entirely through the slot.
- This post receives a torsion force as the wing is being cammed through the slot.
- This torsion force returns the wing to a relaxed position once it has passed through the slot.
- the wing has wedge surfaces spaced on opposed sides of the post, as does the slot. In this way, surfaces on both sides ofthe post are applying a torsion force to the post as the wing moves through the slot.
- the present invention thus provides a resilient snap fit connection for holding two cover portions together.
- the two cover portions secure a filter element for a vehicle engine.
- the wing is simply turned in an opposed direction, similar to that achieved by the wedge surface in the slot.
- the two cover portions may then be moved away from each other with the wing portion moving through the slot.
- Figure 1 is a perspective view showing the main components of the inventive cover mechanism.
- Figure 2 is an assembled cross-sectional view.
- Figure 3 is a top view showing portions ofthe snap fit connection.
- a filter assembly 20 has a top cover portion 1 secured to a bottom cover portion 2.
- a post 3 is formed off of a flange 4 attached by gussets 5 to the body ofthe lower cover 2.
- a filter seal 6 and a filter element 7 are positioned on the lower cover 2.
- the upper cover 1 is removable from the lower cover portion, and may pivot, or may be movable in any other known direction.
- a wing 8 is secured to the post 3, and has a pair of wing portions 9.
- a slot flange 10 in the upper cover 1 has a slot 12 to receive a wedged surface 11 from the wing portions 9. Wedged portions 11 move through slot 12, which has mating wedged portions 13.
- a bottom end 14 ofthe wing 8 will sit atop overlap surfaces 22 once the wing has moved through the slot.
- An axis 15 ofthe post 3 receives torsion as the wing is pivoted by the wedged surfaces.
- Flat surfaces 18 on the wing 8 are formed on an opposed face of the wing portions 9 from the wedged surfaces 11.
- flat surfaces 19 are formed in the slot 12 on opposed surfaces from the wedges 13.
- a dimension 21 ofthe slot 12 is sufficient to receive the width of the wing portions at their lower most extent.
- the wing 8 has moved through the slot 12.
- Wedged surfaces 13 have cammed the wedge surface 11 from the wing portions 9.
- This causes the wing portions 9 to pivot relative to the central axis 15.
- This causes a torsion force in the post 3.
- the wing portions 9 pivot back due to the torsion built up in the post 3.
- the wedged portions 11 ofthe wing portions 9 thus overlap the overlap areas 22 on the slot flange 10 of the upper part 1.
- the wing portions are merely pivoted in the same direction as cammed by the wedged surfaces, at which time the upper cover 1 can be removed from the lower cover 2.
- Figure 3 is a top view showing the overlap areas 22 covered by the wedged surfaces 11 ofthe wing portions 9. As can be seen, there is clearance forward ofthe flat portions 19 such that should one pivot the wing portions 9 counterclockwise as shown in Figure 3, the slot 12 may then be moved off of the winged portions.
- the present invention provides a simple and secure way for securing two cover portions of an air filter system together. Although a preferred embodiment of this invention has been disclosed, a worker in this art would recognize that many modifications would come within the scope of this invention. For that reason the following claims should be studied to determine the true scope and content of this invention.
