Oil funnel

Abstract

An oil funnel for use in draining the oil from an automotive engine oil pan. The upper end of the oil funnel is selectively magnetically attached to the bottom of the oil pan around the drain plug thereof. The oil funnel has a semi-circular slot formed therein. A flexible tubular member, having an open outer end and a closed inner end, is positioned in the oil funnel inwardly of the slot. The user of the oil funnel may insert the user's thumb, index finger and perhaps the user's middle finger inwardly through the slot and into the interior of the tubular member whereby the user may remove the drain plug from the oil pan without coming into direct contact with the drain plug. The flexible tubular member prevents the draining oil from coming into contact with the user's hand.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(16) Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

(17) The oil funnel of this invention is referred to by the reference numeral 10. Oil funnel 10 includes a truncated conical-shaped hollow funnel portion 12 having a lower open end 14 and an upper open end 16. Funnel portion 12 is preferably comprised of a plastic material such as TPE silicone. Four plastic covered and semi-circular magnetic plates 18, 20, 22 and 24 extend horizontally outwardly from the exterior of funnel portion 12 at the upper end thereof. The magnetic plates 18, 20, 22 and 24 do not restrict the open upper end 16 of funnel portion 12. Funnel portion 12 has a semi-circular slot 26 formed therein. Slot 26 has an upper end 28, a lower end 30, a first side edge 32 and a second side edge 34. The numeral 36 refers to a flexible tubular member which has an open outer end 38 and a closed inner end 40. Preferably, tubular member 36 is comprised of a plastic material. The outer end 38 of tubular member 36 is secured to the upper end 28, the lower end 30, the first side edge 32 and the second side edge 34 of slot 26. The inner end 40 of tubular member 36 is crescent-shaped as seen in FIG. 3 with the wings 42 and 44 thereof defining a vertical opening 46 therebetween. A perforated screen 48 is positioned in funnel portion 12 below the tubular member 36 and extends between the side walls of funnel portion 12.

(18) The oil funnel 10 of this invention is configured to be used with an automotive engine oil pan 50 having a drain plug 52 threadably mounted in a drain opening 54 formed in the bottom 56 of the oil pan 50, having oil 58 therein, as will now be described.

(19) Preferably, the length of the oil funnel 10 is about 12.80 inches. Preferably, the diameter of the lower end 14 of the funnel portion 12 is about 1.36 inches. Preferably, the diameter of the upper end 16 of the funnel portion 12 is about 2.70 inches. Preferably, the width of the slot 26 is about 1.08 inches. Preferably, each of the plates 18, 20, 22 and 24 has a radius of 1.07 inches. Preferably, the distance between the outer ends of plate 18 and 22 is about 4.70 inches. Preferably, the distance between the outer ends of plates 20 and 24 is about 4.70 inches. Preferably, the plates 18, 20, 22 and 24 are embedded in plastic.

(20) For descriptive purposes, the numeral 60 refers to a person's hand including a thumb 62, index finger 64 and middle finger 66. The numeral 68 refers to a commonly used wrench. The drain plug 54 is loosened somewhat by the use of the wrench 68 without any oil 58 leaking from the drainage opening 54. The funnel 10 is then positioned below the drain plug 54 as seen in FIG. 7. The funnel 10 is then raised upwardly from the position of FIG. 7 to the position of FIG. 8 so that the magnetic plates 18, 20, 22 and 24 are magnetically attracted and secured to the bottom 56 of the oil pan 50 with the drain plug 52 being centrally received in the open upper end 16 of funnel portion 12. The person then inserts the person's thumb 62, index finger 64 and perhaps the middle finger 66 into the slot 26 and into the open outer end 38 of the flexible tubular member 36 as seen in FIG. 9. The person then grasps the loosened drain plug 52 and further loosens the drain plug 52 until the drain plug 52 is completely removed from the drain opening 54 as seen in FIG. 10. The person then drops the drain plug 52 which falls onto the screen 48. The oil 58 then drains downwardly through the drain opening 54 as seen in FIG. 10. The oil draining from the drain opening 54 passes downwardly through the opening 46 without coming into direct contact with the person's fingers or hand since the person's fingers are enclosed in the tubular member 36. The oil 58 drains from the lower end 14 of the funnel portion 12 into a suitable container.

(21) When the oil drain procedure has been completed, the magnetic plates 18, 20, 22 and 24 are disengaged from the bottom 56 of the oil pan 50. The drain plug 52 is then threadably inserted into the drain opening 54.

(22) As stated above, if the oil pan 50 is aluminum, the magnetic plates 18, 20, 22 and 24 will not magnetically adhere to the oil pan 50. In that case, Applicant has provided a system to allow the oil funnel 10 to be secured to the aluminum oil pan. Applicant's system involves a plurality of magnetically attractive flat discs 70 comprised of iron or the like. Each of the flat discs 70 include a lower side 72 and an upper side 74. A double-sided adhesive tape 76 has its lower side adhesively secured to the upper side 74 of each of the discs 70. The upper side of each of the double-sided adhesive tape 76 has a flexible sheet, tape or liner 78 selectively covering the upper side of the tapes 76. When it is desired to attach the discs 70 to the underside of the aluminum oil pan, the tape liners 78 are peeled from the upper side of the tapes 76 as shown in FIG. 13 to expose the upper side of the double-sided adhesive tape 76. The discs 70 are then pressed onto the underside of the aluminum oil pan. The discs 70 are then attached to the underside of the oil pan in the manner as seen in FIG. 14. The discs 70 will be attached to the aluminum oil pan so as to be aligned with each of the magnetic plates 18, 20, 22 and 24. When so positioned, the oil funnel 10 will be raised with respect to the oil pan so that the magnetic plates 18, 20, 22 and 24 will magnetically adhere to the discs 70.

(23) When the oil draining procedure has been completed, sufficient downward force is applied to the hollow funnel portion 12 to separate the magnetic plates 18, 20, 22 and 24 from the discs 70.

(24) Thus, it can be seen that a novel oil funnel 10 has been provided which enables a person to drain the oil from an automotive engine oil pan 50 without ever coming into direct contact with any of the oil being drained from the engine oil pan 50.

(25) Thus, it can be seen that the invention accomplishes at least all of its stated objectives.

(26) Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
