Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to heat shields, and more particularly, but not by way of limitation, to a heat shield apparatus for the solenoid of a starter wherein the heat shield apparatus is clippingly connected to the solenoid.
2. Description of Related Art
Starters for automobiles are well known in the art. In general, a starter is provided with a solenoid for moving a drive gear into a flywheel engaging position when the automobile is started. The solenoid of the starter defines a coil receiving space adapted to receive an internal solenoid coil having a plurality of windings of wire wrapped thereabout. Because the starter and the solenoid are disposed near the engine and are subjected to a great deal of heat, it is necessary to shield the solenoid from such heat. Otherwise, the insulation on the wire of the internal solenoid coil will melt and short out such coil or, the overheated solenoid may draw an excess of current from the automobile's battery thereby leading to premature battery failure. To protect the solenoid of the starter from heat, automobiles presently are provided with a solenoid heat shield as original equipment.
These prior art solenoid heat shields are typically provided with a single body member positioned between the solenoid and the engine. Depending upon the engine and the model of automobile, these prior art solenoid heat shields vary widely in configuration and mounting equipment. Typically, the body member is connected to the starter by arms with holes formed therethrough for accommodating a bolt whereby the arms are bolted to the starter, for example.
While the prior art solenoid heat shields function to protect the solenoid from heat, problems have been encountered in the removal and/or the replacement of the solenoid heat shields and starters. For example, when replacement of a starter is required, a problem has been that the original solenoid heat shield will not mount to the replacement starter because the replacement starter may not have the same dimensions as the original starter. In other words, if the replacement starter is slightly larger or smaller than the original starter then the original heat shield cannot be utilized. Thus, one has to either buy a new solenoid heat shield to replace the original solenoid heat shield or operate the replacement starter without a heat shield thereby leading to premature starter failure.
Due to the great number of different configurations of the prior art solenoid heat shields presently available it is impractical for solenoid heat shields to be sold on the aftermarket. Therefore, a replacement prior art solenoid heat shield must be obtained from the original automobile manufacturer, such as General Motors, and normally costs a consumer more than the replacement starter.
To this end, a need has long existed for a heat shield for the solenoid of a starter that can be installed on various makes and models of automobiles and that can replace the original solenoid heat shield provided by the automobile manufacture without requiring the same specialized mounting equipment as the original solenoid heat shield. It is to such an apparatus that the present invention is directed.

DETAILED DESCRIPTION
Referring now to the drawings and in particular to FIG. 1, a universal heat shield apparatus 10 (FIGS. 1, 2 and 5) constructed in accordance with the present invention is shown connected to a solenoid 12 (FIGS. 1, 3, 4 and 5) of a starter 14 (FIG. 1) mounted near an engine (not shown). The starter 14 is a conventional starter for an automobile of the variety typically manufactured by General Motors. It should be understood that the starter 14 can be any starter so long as the starter 14 has a solenoid connected thereto.
The solenoid 12 of the starter 14 has a continuous sidewall 16 (FIGS. 1 and 5) defining a coil receiving space 18 (FIG. 1) adapted to receive an internal solenoid coil 20 (FIG. 1). The solenoid 12 has a diameter 22 (FIG. 1) and a radius 24 (FIG. 1). The use and the construction of starters, such as the starter 14, are well known in the art. Thus, no further explanation is deemed necessary to teach one skilled in the art to use or construct the starter 14 or the solenoid 12.
Referring now also to FIG. 2, the heat shield apparatus 10 is provided with a heat shield 26 (FIGS. 1, 2 and 5) and a clipping assembly 28 (FIG. 2) for clipping the heat shield 26 to the solenoid 12. The heat shield 26 of the heat shield apparatus 10 has a first end 30 (FIGS. 1 and 2), a second end 32 (FIGS. 1 and 2), a first side 34 (FIGS. 1 and 2), a second side 36 (FIGS. 1 and 2), an upper surface 38 (FIGS. 1 and 2), a lower surface 40 (FIGS. 1 and 2), a planar first side portion 42 (FIGS. 1 and 2), a planar second side portion 44 (FIGS. 1 and 2) and a planar medial portion 46 (FIGS. 1 and 2).
The first side portion 42 of the heat shield 26 has a first end 48 (FIGS. 1 and 2) and a second end 50 (FIGS. 1 and 2). The second side portion 44 of the heat shield 26 has a first end 52 (FIGS. 1 and 2) and a second end 54 (FIGS. 1 and 2). The medial portion 46 of the heat shield 26 has a first end 56 (FIGS. 1 and 2) and a second end 58 (FIGS. 1 and 2). The first end 48 of the first side portion 42 of the heat shield 26 is connected to the first end 56 of the medial portion 46 of the heat shield 26. The first end 52 of the second side portion 44 of the heat shield 26 is connected to the second end 58 of the medial portion 46 of the heat shield 26. The first side portion 42 and the second side portion 44 extend downwardly from the medial portion 46 typically at an angle of about 65.degree. relative to a horizontal centerline 60 (FIG. 2) for forming the heat shield 26 into a substantially U-shape configuration so that the heat shield 26 substantially covers the solenoid coil 20 of the solenoid 12 when the heat shield 26 is clipped thereto for shielding the solenoid coil 20 from heat generated by the engine.
Although the heat shield 26 is shown in FIGS. 1 and 2 as having a substantially U-shaped configuration, it is to be understood that the heat shield 26 may assume any geometric, non-geometric or asymmetrical configuration. For example, the heat shield 26 may assume a triangular or semi-circular configuration.
The heat shield 26 is preferably of unitary construction and formed from a sheet of material capable of reflecting and/or dissipating heat, such as a sheet of tin, aluminum or galvanized steel. Typically, the heat shield 26 is formed from 26 gauge galvanized steel sheet metal. However, it will be appreciated by those skilled in the art that the heat shield 26 can be fabricated of any material capable of serving as a heat shield, such as a ceramic material. In addition, the heat shield 26 can be constructed from two or more sheets of the same or different types of materials stacked one on top of the other.
The heat shield 26 is further provided with a length 62 (FIG. 2), a width 64 (FIG. 2) and a height 66 (FIG. 2). The length 62 of the heat shield 26 extends generally between the first end 30 and the second end 32 of the heat shield 26 and is typically about 83.50 mm. The width 64 of the heat shield 26 extends generally between the first side 34 and the second side 36 of the heat shield 26 and is typically about 105 mm. The height 66 of the heat shield 26 extends generally between the parallel planes in which the second end 50 of the first side portion 42 and the medial portion 46 are disposed. The height 66 of the heat shield 26 is typically about 59 mm.
The clipping assembly 28 will now be described. The clipping assembly 28 includes at least one clip, a first clip and a second clip being shown in FIG. 2 and designated by the reference numerals 70a and 70b, respectively. Because the first clip 70a and the second clip 70b are identical in construction and operation, for purposes of clarity only the first clip 70a will be described herein. However, like parts on the first and second clips 70a and 70b, respectively, will be designated in the drawings with the same numeral but different alphabetic suffixes a and b, respectively.
To provide support to the heat shield 26, the first clip 70a is secured to the heat shield 26 in any suitable manner, such as by riveting the first clip 70a to the heat shield 26 with a rivet 72a (FIGS. 2 and 5). While only one rivet is shown connecting the first clip 70a to the heat shield 26, it should be understood that any number of rivets can be used to secure the first clip 70a to the heat shield 26 and preferably at least two rivets are used to secure the first clip 70a to the heat shield 26. An insulator 74a (FIGS. 2 and 5) is interposed between the first clip 70a and the heat shield 26 to reduce the amount of heat that is transmitted from the heat shield 26 to the first clip 70a. The insulator 74a is fabricated of a non-heat conductive material, such as phenolic.
The first clip 70a of the heat shield apparatus 10 is disposed near the first end 30 of the heat shield 26 and the second clip 70b of the heat shield apparatus 10 is disposed near the second end 32 of the heat shield 26. Typically, the first clip 70a is disposed about 7.5 mm from the first end 30 of the heat shield 26 and the second clip 70b is disposed about 22 mm from the second end 32 of the heat shield 26.
The first clip 70a serves to clippingly and detachably connect the heat shield 26 to the sidewall 16 of the solenoid 12 so that the heat shield apparatus 10 is frictionally maintained thereon. It should be noted that the first clip 70a also serves to space the heat shield 26 a predetermined distance from the sidewall 16 of the solenoid 12 so that air freely circulates about the heat shield 26 and dissipates heat therefrom.
The first clip 70a is constructed to be force fitted against the sidewall 16 of the solenoid 12 and shaped to conform to the sidewall 16 while permitting the first clip 70a to be slidably rotated about the sidewall 16 for positioning the heat shield 26 between the solenoid coil 20 of the solenoid 12 and the engine as indicated by arrows 76 and 78 in FIG. 1 when the first clip 70a is disposed on the solenoid 12. It should be noted that the capability of the first clip 70a to be rotated about the solenoid 12 allows the heat shield apparatus 10 to be used with starters which are mounted on either the right or left hand side of the engine, for example.
The first clip 70a has a diameter 80a (FIG. 2) slightly less than the diameter 22 of the sidewall 16 of the solenoid 12 so that when the first clip 70a is clipped onto the solenoid 12, the first clip 70a fits snugly against the solenoid 12. Typically, the diameter 80a of the first clip 70a is about 56 mm.
The first clip 70a has an arc-shaped first arm 82a (FIGS. 2 and 5) and an arc shaped second arm 84a (FIGS. 2 and 5) cooperating to define a solenoid receiving slot 86a (FIGS. 2 and 5) configured to accommodate the sidewall 16 of the solenoid 12. The first arm 82a has a first end 88a (FIGS. 2 and 5), a second end 90a (FIGS. 2 and 5), and a shoulder portion 91a (FIGS. 2 and 5) disposed near the second end 90a thereof. The second arm 84a has a first end 92a (FIGS. 2 and 5), a second end 94a (FIGS. 2 and 5), and a shoulder portion 95a (FIGS. 2 and 5) disposed near the second end 94a thereof. The first end 88a of the first arm 82a is connected to the first end 92a of the second arm 84a. The second end 90a of the first arm 82a is spaced a distance from the second end 94a of the second arm 84a such that the shoulder portion 91a is spaced a distance from the shoulder portion 95a for providing the first clip 70a with a solenoid receiving passageway 96a (FIGS. 2 and 5) in open communication with the solenoid receiving slot 86a. The solenoid receiving passageway 96a has a width 98a (FIGS. 2 and 5) extending between the shoulder portions 91a and 95a typically of 20.4 mm when the solenoid 12 is not disposed in the solenoid receiving slot 86a.
To facilitate the insertion and removal of the solenoid 12 from the solenoid receiving slot 86a via the solenoid receiving passageway 96a, the first arm 82a is provided with a curved lip 99a (FIGS. 2 and 5) extending outwardly from the shoulder portion 91a and the second arm 84a is provided with a curved lip 100a (FIGS. 2 and 5) extending outwardly from the shoulder portion 95a. It should be noted that the curved lips 99a and 100a of the first and second arms 82a and 84a, respectively, extend outwardly at an angle of about 45.degree. relative to a vertical centerline indicated by a dashed line 102a (FIG. 2).
The second ends 90a and 94a of the first and second arms 82a and 84a, respectively, of the first clip 70a are disposed a distance 104a (FIG. 2) from the first ends 88a and 92a of the first and second arms 82a and 84a, respectively. The distance 104a is greater than the radius 24 of the solenoid 12 so that when the first clip 70a is disposed on the solenoid 12, the second end 90a of the first arm 82a and the second end 94a of the second arm 84a extend about at least a portion of the side of the solenoid 12 disposed opposite from the heat shield 26 thereby permitting the second ends 90a and 94a to frictionally grip the sidewall 16 of the solenoid 12 and resist the removal of the heat shield apparatus 10 therefrom. The distance 104a is typically about 62 mm.
The first clip 70a is constructed of a material having an elastic quality for permitting the first and second arms 82a and 84a to be selectively movable between a solenoid clamping position and a solenoid receiving position. When the first arm 82a and the second arm 84a of the first clip 70a are positioned in the solenoid clamping position (FIGS. 3 and 4), the width 98a of the solenoid receiving slot 96a is less than the diameter 22 of the sidewall 16 of the solenoid 12 such that the first and second arms 82a and 84a of the first clip 70a are snugly biased against the sidewall 16 of the solenoid 12 when the first clip 70a is disposed on the solenoid 12. When the first arm 82a and the second arm 84a of the first clip 70a are positioned in the solenoid receiving position (shown in FIG. 5), the second end 90a of the first arm 82a is moved away from the second end 94a of the second arm 84a (as indicated by the arrows 106a and 108a of FIG. 2) until the width 98a of the solenoid receiving passageway 96a is greater than the diameter 22 of the sidewall 16 of the solenoid 12 (FIG. 5) for permitting the first clip 70a to be inserted onto the solenoid 12.
In the preferred embodiments which are shown in the drawings, the first arm 82a and the second arm 84a of the first clip 70a are integrally constructed. However, it should be understood that the first arm 82a and the second arm 84a of the first clip 70a can be two or more separate members with each member individually securable to the other members or the heat shield 26. The first clip 70a is desirably formed from a strip of material having elastic and heat resilient qualities, such as a strip of blued spring steel having a thickness of 1.10 mm.
Referring to FIG. 5, the installation of the heat shield apparatus 10 on the solenoid 12 of the starter 14 will be discussed. To install the heat shield apparatus 10 on the solenoid 12 of the starter 14, the heat shield apparatus 10 is clipped onto the solenoid 12 by disposing the curved lip 99a of the first arm 82a and the curved lip 100a of the second arm 84a against the sidewall 16 of the solenoid 12. Then, force is applied to the heat shield 26 in a direction 120a (FIG. 5) so as to bias the first clip 70a against the solenoid 12 and force the curved lips 99a and 100a in the directions indicated by arrows 122a (FIG. 5) and 124a (FIG. 5) against the elastic quality of the first clip 70a and into the solenoid receiving position for allowing the solenoid 12 to slide into the solenoid receiving slot 86a. The elastic quality of the first clip 70a then biases the outwardly curved lips 99a and 100a in an opposite direction (as indicated by arrows 126a (FIG. 5) and 128a (FIG. 5)) so that the first arm 82a and the second arm 84a of the first clip 70a are moved into the solenoid clamping position for gripping the solenoid and for clippingly and detachably connecting the first clip 70a onto the solenoid. In this position, the first arm 82a and the second arm 84a of the first clip 70a substantially conform to the shape of the sidewall 16 of the solenoid 12 of the starter 14 and are biased snugly against the sidewall 16 by the elastic quality of the first clip 70a for frictionally maintaining the heat shield apparatus 10 in a selected position. The heat shield apparatus 10 is then slidably rotated about the solenoid 12 and frictionally maintained thereon in a selected position by the first clip 70a so that the heat shield 26 is positioned between the solenoid 12 and the engine thereby shielding the solenoid coil 20 of the solenoid 12 from heat generated by the engine.
Embodiment of FIG. 3
FIG. 3 illustrates another embodiment of a clip 70c constructed in accordance with the present invention to be used in combination with the heat shield 26. The clip 70c is constructed and operates identically to the first clip 70a which was hereinbefore described with reference to FIGS. 1, 2 and 5, except that the clip 70c has a raised portion 140c (FIG. 3). The raised portion 140c serves to space the heat shield 26 of the heat shield apparatus 10 a predetermined distance from the solenoid 12 when the heat shield apparatus 10 is disposed thereon so that air may freely circulate between the heat shield 26 and the solenoid 12. The raised portion 140c of the clip 70c is also provided with a flat surface 142c (FIG. 3) adapted to fit flat against the heat shield 26 and provide the heat shield apparatus 10 with a more stable structure.
The flat surface 142c has a first end 144c (FIG. 3), a second end 146c (FIG. 3) and a width 148c (FIG. 3) extending therebetween. The width 148c is typically about 20 mm.
Embodiment of FIG. 4
FIG. 4 illustrates another embodiment of a clip 70d constructed in accordance with the present invention to be used in combination with the heat shield 26. The clip 70d is constructed and operates identically to the first clip 70a which was hereinbefore described with reference to FIGS. 1, 2 and 5, except that a first arm 82d (FIG. 4) is provided with a substantially planar flange portion 154d (FIG. 4) and a second arm 84d of the clip 70d is provided with a substantially planar flange portion 156d (FIG. 4). Each of the flange portions 154d and 156d are provided with an aperture (not shown) formed therethrough configured to accommodate a connecting member 158d (FIG. 4), such as a bolt for providing the clip 70d with a tighter clamping about the sidewall 16 of the solenoid 12 when the clip 70d is in the solenoid clamping position. The connecting member 158d is disposed through the apertures once the clip 70d has been disposed on the solenoid 12 and is maintained thereon via a nut 160d (FIG. 4), for example.
The heat shield apparatus 10 of the present invention was tested by clipping the heat shield apparatus 10 to the solenoids of the starters of various makes and models of automobiles. It was found in the study that the heat shield apparatus 10 fit on every General Motors product tested with the exception of the 1984 Oldsmobile Toronado. The heat shield apparatus 10 would not work with the 1984 Oldsmobile Toronado because there was not enough clearance between the solenoid and the engine for the heat shield apparatus 10 to be slidably rotated therebetween once the heat shield apparatus 10 was clippingly and detachably connected to the sidewall of the solenoid.
From the above description it is clear that the present invention is well adapted to carry out the objects and to attain the advantages mentioned herein as well as those inherent in the invention. While a presently preferred embodiment of the invention has been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art. The exact dimensions and proportions of the elements described herein are not essential to the practice of the present invention, but are intended to illustrate the general nature of the embodiments of the present invention. Thus, changes may be made in the embodiments of the invention described herein, or in the parts or the elements of the embodiments described herein, or in the steps or sequence of steps of the methods described herein, without departing from the spirit and/or the scope of the invention as defined in the following claims.
