DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings, a new and improved magnet assembly for an oil filter and an oil pan embodying the principles and concepts of the present invention will be described.

Turning to FIGS. 1-5 , there is shown a first embodiment of the magnet assembly of the invention for an oil filter canister generally designated by reference numeral 10 . In the first embodiment, a magnet assembly for an oil filter 10 comprises a first bottom magnet unit reception cup member 12 made from ferromagnetic material, wherein the first bottom magnet unit reception cup member 12 includes a first retention pin reception channel 13 . A second bottom magnet unit reception cup member 14 is made from ferromagnetic material and is located adjacent to the first bottom magnet unit reception cup member 12 and is coplanar therewith. The second bottom magnet unit reception cup member 14 includes a second retention pin reception channel 15 which is in registration with the first retention pin reception channel 13 . A plurality of first magnet units 20 are placed in the first bottom magnet unit reception cup member 12 in a first magnetic polarity orientation. A plurality of second magnet units 22 are placed in the second bottom magnet unit reception cup member 14 in a second magnetic polarity orientation. The second magnetic polarity orientation is opposite the first magnetic polarity orientation. A locking pin 24 is received in the first retention pin reception channel 13 and the second retention pin reception channel 15 . Assembly-to-vehicle mounting means, connected to the first bottom magnet unit reception cup member 12 and the second bottom magnet unit reception cup member 14 , are provided for mounting the magnet assembly apparatus 10 onto the portion of a motor vehicle. The locking pin 24 serves both to stabilize the first bottom magnet unit reception cup member 12 with respect to the second bottom magnet unit reception cup member 14 and to fix the first retention pin reception channel 13 and the second bottom magnet unit reception cup member 14 to the assembly-to-vehicle mounting means.

A locking clip 25 is connected at an end of the locking pin 24 for preventing the locking pin 24 from slipping out from the first retention pin reception channel 13 and the second retention pin reception channel 15 after the locking pin is received therein and passes through support members 32 as will be explained further below.

Third magnet units 26 are oriented transversely between the first bottom magnet unit reception cup member 12 and the second bottom magnet unit reception cup member 14 . The third magnet units 26 are oriented along a third magnetic polarity orientation which causes magnetic fields of the first magnet units 20 and the second magnet units 22 to be reinforced. The third magnet units 26 also contribute to stabilization of the first retention pin reception channel 13 with respect to the second bottom magnet unit reception cup member 14 . To facilitate retention of the third magnetic units 26 , suitable magnetic unit receiving receptacles are formed in the confronting faces of the first and second bottom magnet unit reception cup members 12 and 14 , substantially as depicted in FIGS. 2-5 .

Also, a first top magnet unit reception cup member 19 , made from ferromagnetic material, can be located opposite the first bottom magnet unit reception cup member 12 , wherein the first magnet units 20 are located between the first bottom magnet unit reception cup member 12 and the first top magnet unit reception cup member 19 . Also, a second top magnet unit reception cup member 21 , made from ferromagnetic material, can be located adjacent to the first top magnet unit reception cup member 19 , wherein the second magnet units 22 are located between the second bottom magnet unit reception cup member 14 and the second top magnet unit reception cup member 21 . The first top magnet unit reception cup member 19 is stabilized with respect to the first bottom magnet unit reception cup member 12 by virtue of the magnetic attraction provided by the first magnet units 20 . Similarly, the second top magnet unit reception cup member 21 is stabilized with respect to the second bottom magnet unit reception cup member 14 by virtue of the magnetic attraction provided by the second magnet units 22 .

Also, fourth magnet units 27 can be provided and oriented transversely between the first top magnet unit reception cup member 19 and the second top magnet unit reception cup member 21 . The fourth magnet units 27 also contribute to the stabilization of the entire magnet assembly apparatus 10 by virtue of magnetic interactions between the fourth magnet units 27 and the first magnet units 20 and the second magnet units 22 . The fourth magnet units 27 are oriented along a fourth magnetic polarity orientation which causes magnetic fields of the first magnet units 20 , the second magnet units 22 , and the third magnet units 26 to be reinforced. To facilitate retention of the fourth magnetic units 27 , suitable magnetic unit receiving receptacles are formed in the confronting faces of the first and second top magnet unit reception cup members 19 and 21 , substantially as depicted in FIGS. 2-5 . The magnetic units 20 , 22 , 26 and 27 contemplated for use in the present invention are conventional cylindrical magnets preferably of the neo-dymium iron boron type.

More specifically, with the first embodiment of the invention, the portion of a motor vehicle to which the magnet assembly apparatus 10 is attached is a top of an oil filter 17 . The magnet assembly-to-vehicle mounting means include magnet unit support members 32 substantially as shown and suitably attached to a housing of an otherwise conventional oil filter 17 such as that commonly used with or on an engine, typically an automobile or truck internal combustion engine. The magnet unit support members 32 include lock pin reception channels 34 . Portions of the locking pin 24 are in registration with the lock pin reception channels 34 for retaining the magnet assembly apparatus 10 on the portion of an oil filter housing and thus, on a portion of a motor vehicle.

To use the embodiment of the invention shown in FIGS. 1-5 , a plurality of first magnet units 20 are placed in the first bottom magnet unit reception cup member 12 in the first magnetic polarity orientation. A plurality of second magnet units 22 are placed in the second bottom magnet unit reception cup member 14 with the second magnetic polarity orientation, which is opposite to the first magnetic polarity orientation. A plurality of third magnet units 26 are placed transversely with respect to the first magnet units 20 and the second magnet units 22 in the third magnetic polarity orientation. The fourth magnet units 27 are placed transversely along the fourth magnetic polarity orientation between the first top magnet unit reception cup member 19 and the second top magnet unit reception cup member 21 . Then, the first top magnet unit reception cup member 19 is placed on top of the first magnet units 20 , and the second top magnet unit reception cup member 21 is placed on top of the second magnet units 22 . As a result, the magnet assembly apparatus 10 is fully assembled.

Then, the magnet assembly apparatus 10 is placed between the magnet unit support members 32 , and the locking pin 24 is threaded through the first lock pin reception channels 34 in the first magnet unit support member 32 , the first retention pin reception channel 13 , the second retention pin reception channel 15 , and the second lock pin reception channel 34 in the second magnet unit support member 32 . Then, the locking clip 25 is placed on the end of the locking pin 24 . In this way, the magnet assembly apparatus 10 is secured to the oil filter cartridge 17 .

When lubricating oil circulates in the engine, ferrous or metal particles in the lubricating oil are attracted to the magnetic fields provided by the respective magnet units, and those particles are trapped on the inside top surface of the oil filter cartridge 17 . When an oil filter 17 is to be replaced, the magnet assembly apparatus 10 is removed from the old oil filter 17 and is installed on a new oil filter cartridge 17 .

Turning to FIGS. 6-9 , in which a second embodiment of the invention is shown, reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In addition, the portion of a motor vehicle to which the magnet assembly apparatus 40 is attached is an oil pan member 36 . In this respect, the magnet assembly-to-vehicle mounting means include a magnet support unit 55 which includes a first attachment ring portion 62 which includes a pair of third retention pin reception channels 56 and which includes a support connector portion 63 extending upward from the first attachment ring portion 62 . The first bottom magnet unit reception cup member 12 and the second bottom magnet unit reception cup member 14 are received in the magnet support unit 55 and secured to the magnet support unit 55 by the locking pin 24 which is threaded through the third retention pin reception channels 56 , the first retention pin reception channel 13 , and the second retention pin reception channel 15 . The support connector portion 63 includes external threads 65 .

A second attachment ring 44 is attached to an inside portion of the oil pan member 36 . The second attachment ring 44 includes internal threads 50 , and the internal threads 50 are engaged with the external threads 65 when the magnet assembly apparatus 40 is attached to the oil pan member 36 .

To use the embodiment of the invention shown in FIGS. 6-9 , the second attachment ring 44 is attached to the inside of the oil pan member 36 using fasteners 52 . The second attachment ring 44 surrounds a relatively large opening in the oil pan member 36 . The magnet support unit 55 is screwed into the second attachment ring 44 . That is, the external threads 65 of the support connector portion 63 are screwed into the internal threads 50 of the second attachment ring 44 .

An assembly of magnets and cups 37 , similar to that described above in connection with the first embodiment of the invention, is also formed. This assembly of magnets and cups 37 includes the first bottom magnet unit reception cup member 12 , the first magnet units 20 , the first top magnet unit reception cup member 19 , the second bottom magnet unit reception cup member 14 , the second magnet units 22 , the second top magnet unit reception cup member 21 , the third magnet units 26 , and the fourth magnet units 27 .

To secure the assembly of magnets and cups in the magnet support unit 55 , the assembly of magnets and cups 37 is inserted into the hollow interior of the magnet support unit 55 . Then, the first retention pin reception channel 13 and the second retention pin reception channel 15 are placed in registration with the third retention pin reception channels 56 in the first attachment ring portion 62 . Then, the locking pin 24 is threaded through the third retention pin reception channels 56 , the first retention pin reception channel 13 , and the second retention pin reception channel 15 . Finally, the locking clip 25 is placed on the end of the locking pin 24 . To remove the assembly of magnets and cups from the oil pan member 36 , the process is reversed.

When lubricating oil circulates in the engine, ferrous or metal particles in the lubricating oil are attracted to the magnetic fields provided by the respective magnet units, and those particles are trapped on the oil-facing top surface 41 of the magnet support unit 55 . As shown by the arrows 42 in FIG. 8 , oil flows next to the oil-facing top surface 41 of the magnet support unit 55 .

Turning to FIGS. 10-13 , a third embodiment of the invention is shown. Reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In addition, the first bottom magnet unit reception cup member 12 and the second bottom magnet unit reception cup member 14 are formed as a single, integrated combination first/second cup member 28 which includes a first cup portion 30 and a second cup portion 31 separated by a inside cup wall 33 . In this respect, the first retention pin reception channel 13 and the second retention pin reception channel 15 are formed as a combination first/second retention pin reception channel 35 .

To assemble the combination first/second cup member 28 , the first magnet units 20 are placed in the first cup portion 30 with a first magnetic polarity orientation, and the second magnet units 22 are placed in the second cup portion 31 with a second magnetic polarity orientation which is opposite to the first magnetic polarity orientation. The magnetic interaction between the first magnet units 20 , the combination first/second cup member 28 , and the second magnet units 22 keeps the first magnet units 20 and the second magnet units 22 retained in the combination first/second cup member 28 . Moreover, due to the relatively thick base of cup member 28 , the latter functions as an effective shunt in the aforementioned magnetic circuit thereby compressing and redirecting the magnetic flux field into the region of oil flow at the proximally located portion of the filter housing. The use of such a “magnetic shunt” to redirect and compress the magnetic flux field in such applications is more fully described in my prior U.S. Pat. No. 5,510,024 in connection with FIGS. 9 and 10 therein, which description hereby is incorporated herein by this reference.

To use the combination first/second cup member 28 embodiment of the invention with the oil filter 17 , as shown in FIG. 10 , the combination first/second retention pin reception channel 35 is placed in registration with the lock pin reception channels 34 of the magnet unit support members 32 , and the locking pin 24 is threaded therethrough. Then, the locking clip 25 is placed on the end of the locking pin 24 .

To use the combination first/second cup member 28 embodiment of the invention with the oil pan member 36 , the second attachment ring 44 , and the magnet support unit 55 , as described above, the combination first/second retention pin reception channel 35 is placed in registration with the third retention pin reception channels 56 , and the locking pin 24 is threaded therethrough. Then, the locking clip 25 is placed at the end of the locking pin 24 . To remove the combination first/second cup member 28 from the oil pan member 36 , the above-described procedure is reversed.

The components of the magnet assembly for an oil filter and an oil pan of the invention can be made from inexpensive and durable metal, especially ferromagnetic material, and plastic materials.

As to the manner of usage and operation of the instant invention, the same is apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation need be provided.

It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved magnet assembly that is low in cost, relatively simple in design and operation, and which is an advantageous improvement for removable and reusable magnet units installed on oil filters. With the invention, a magnet assembly is provided which is an improvement in removable and reusable magnet units installed in oil pans.
