FR2723872A1 - Vehicle oil filter removal tool - Google Patents

Abstract

The tool comprises grippers formed of two arms (12/a) and 4/a). The lower arm has a hollow to clear the upper jaw. The two arms are joined together by an axle. The device also has an upper jaw (12) and a lower jaw (4), the axle (3) may be made up of a screw which can be placed in any one of three available holes (8).

Description

PATENT
The present invention relates to the field of tooling for vehicles, and more particularly a PLIER, for screwing and unscrewing the oil filter on the engine of a vehicle.

There is a filter release key with a handle, but the lever arm is short.

This technical tool of PLIERS, for the oil filter in the engine of a vehicle allows the easy access of the work of the PINC, the easy handling and the speed to unscrew and screw the oil filter, in all shapes and profiles.

This device intended for screwing and unscrewing the oil filter for the vehicle engine. Facilitates access and rapidity of unscrewing and screwing the oil filter, it is characterized in that it consists of a clamp formed of 2 parts (12) and (4) or jaws: a normal upper jaw (12) and a lower jaw (4).

In the case of a filter (ll), with outside parts (13), in these are placed exactly several lugs (6), which are located inside the jaws of the clamp.

Each of these jaws is extended beyond a pivot axis (3), a long gripper arm with a great length (S) for example: 36 cm, consisting of the arms (12 / a) and (4 / a) which offer an easy manipulation by the pin. These jaws (12) and (4) are articulated in an adjustable way one on the other. For the adjustment of this pinne is placed a system with an axis formed by a screw (3), which can be moved into one of 3 holes, (8) and (9), for the 3 existing sizes of oil filter (11).

This clamp will preferably be made with STEEL combined with VAADIUK chrome.

The manohe will be covered with rubber or plastic to facilitate handling and protect the hand. The screw (3) can be replaced easily, to unscrew and screw as desired the 3 existing format modules of the oil filters.

Figure 1 shows a top view of a part of the clamp comprising the upper jaw (12).

FIG. 2 represents a top view of a part of the clamp comprising the lower part (4) with a hole (14) for passing the upper part (12).

FIG. 3 represents a front view @@ the part of the upper jaw clamp, with 7 pins (6) on the inner face.

FIG. 4 represents a front view of the part of the lower jaw pliers, with 5 pins (6), (in smaller number) on its inner face.

5 shows a sectional view of the articulation part of the clamp. Referring to these drawings, the device shown comprises a screw (3) and a stop tube (10) received in the holes (8) and (9 ), with locking by washer (15 / a), nut (15) and clamping pin (7).

FIG. 6 represents a front view (6/1): at least 3 holes (8), the first of which with the screw (3) assembled, (6/2): the only hole (9) on the other branch upper (12) only of the pliers, (6/3): the 3 separate holes (8) of the lower branch (4) only of the pliers.

Figure 7 shows a front view of the oil filter clamp with a total arm length (S) of 36 cm for the two arms (12 / a) + (4 / a) and (12) + (4) .

FIG. 8 represents a front view of the open clamp, with its lugs (6).

Figure 9 shows a front view on a larger scale of the pineapple, full size, with the oil filter (11) on the engine of the vehicle.

The upper curved jaw (12) is curved downwards in about 1/4 of a circle at the end of an offset offset towards the top of the arm (12 / a).

The lower curved jaw (4) is curved downwards on an arc less than the 1/4 of a circle, placed approximately 900 with respect to the lower arm (4 / a). These 2 jaws are arranged, facing each other so as to define a bearing surface corresponding to the circular shape of the filter, substantially diametrically opposite.
