Description
Background of the Invention
The present invention relates to lockable instrument panel covers of a type mounted for movement between an operative position covering and protecting instruments from vandalism and a stored position permitting visual and/or manual access to instruments carried by the panel.
The use of lockable instrument panel covers on vehicles or equipment, which are often left unattended at unsecured work sites for extended periods of time, is commonplace. While designers of these prior art covers have attempted to create covers which are effective, inexpensive and ones which operators will find easy, convenient and acceptable to use, many of the covers suffer inadequacies relative to one or more of these design criteria.
For example, as concerns effectiveness, the mountings of many of the covers are such that the covers can easily be opened by using ordinary tools and/or pry bars and the like; and, as concerns operator acceptability, many of the covers are prone to rattling when placed in their stored positions resulting in their being removed by the operators.
Summary of the Invention
According to the present invention, there is provided a novel instrument panel cover.
An object of the invention is to provide an instrument panel cover of simple construction mounted by means, which are entirely inaccessible when the cover is in its operative position and which function to guide the panel cover between its operative and stored positions.
A further object of the invention is to provide a panel cover including a key-operable lock cam and cooperating structure to effect a rugged lock assembly for releasably retaining the panel cover in its operative position.
Yet another object is to provide a panel cover including a clip perforated such as to form a resiliently expandable opening for receiving an end of a ball stud, which is fixed to a panel housing wall and operates to hold the cover in a stored position adjacent the housing wall.
These and other objects will become apparent from a reading of the ensuing description together with the appended drawing.

FIG. 2 is a view taken facing the top of the instrument panel illustrated in FIG. 1 and with the panel cover being shown in its operative position.
FIG. 3 is a vertical sectional view taken along the line 3--3 of FIG. 2, but additionally showing the stored position of the cover in dashed lines.
Description of the Preferred Embodiment
Referring now to FIG. 1, therein is shown a control console 10 as might be found on any of a variety of vehicles commonly used where it is necessary to protect instruments from vandalism. The console 10 includes an instrument panel housing 12 including a rectangular panel-receiving opening defined by forward and rearward walls 14 and 16, respectively, inclined downwardly and forwardly from respective upper ends thereof and joined by spaced, parallel, vertical left and right side walls 18 and 20. A downwardly and rearwardly inclined instrument panel 22 is mounted in the rectangular opening and includes an upper rectangular section 24, a lower rectangular section 26 disposed parallel to but stepped downwardly from the section 24 and a connecting section 28 joining the sections 24 and 26.
It is here noted that the upper panel section 24 carries a plurality of instruments 30 covered by relatively tough, virtually unbreakable, transparent synthetic resin material and, therefore, there is no need to further protect the instruments from vandalism.
However, the lower panel section 26 carries a push-pull light switch 32, a rotary control switch 34 and a park brake release handle 36 which all need to be secured to ensure that no unauthorized person turns on the lights or other electrical equipment or releases the vehicle brakes to thus permit the vehicle to roll.
Accordingly, provided for releasably blocking access to the instruments carried by the lower panel section 26 is a panel cover 38. As viewed in its operative position illustrated in FIGS. 2 and 3, the panel cover 38 includes a main central portion of generally L-shaped cross-section comprised of an upper first rectangular section 40, disposed in spaced parallel relationship to the panel section 26 and to a lower margin of the upper panel section 24, and a lower second rectangular section 42, disposed generally orthogonally to and having a lower edge abuttingly engaged with a lower portion of the panel section 26. For a purpose hereinafter described, a pair of vertical skirts 44 are provided as continuations of the right and left ends of the first cover section 40. The cover also includes a skirt 46 which forms a continuation of the top end of the section 40 and includes a first portion which extends orthogonally to the section 40 and engages the lower margin of the panel section 24 and terminates in a reversely bent portion located entirely beneath the section 40 and defining a forwardly opening channel 47, the lower leg of which includes a pair of transversely spaced, forwardly projecting tabs 48.
Located in the connecting section 28 of the panel 22 are a pair of transversely spaced tab receptacles 50 in which the tabs 48 are respectively received. Thus it will be appreciated that when the cover 38 is in its operative position, it cooperates with the panel 22 and sidewalls 18 and 20 to define an enclosure 51 in which the instruments carried by the lower panel section 26 are located.
The cover 38 is releasably held in its operative position through means of a lock mechanism comprising a key-operable lock 52 carried by the cover 38 and including a locking tab 54 located beneath and here shown engaged with the underside of an upper angled end 56 of a locking rod 58 having a lower threaded end received in a nut 60 welded to an underside location of the panel section 26 and held in place by a jam nut 62. Thus it will be appreciated that the angled end 56 of the rod 58 may be adjusted for proper cooperation with the locking tab 54.
It is herenoted that a locking tab back-up plate 64 extends between and is welded to the skirt 46 and cover section 42 at a central location between the opposite ends of the cover 38. The plate 64 is disposed such that it gives additional support to the tab 54 and thereby increases the resistance the tab 54 would have to bending in the event that someone would attempt to pry off the cover 38, it being noted that the tabs 48 also resist such prying.
Provided for pivotally supporting and guiding the panel cover 38 for movement between its operative and inoperative positions, respectively illustrated in solid and dashed lines in FIG. 3, is a unitary hinge rod 66. The rod 66 includes a central straight portion 68 pivotally received in right and left mounting brackets 70 fixed to the underside of the cover section 40 adjacent opposite ends thereof. Dog leg-shaped portions 72 extend perpendicular to and are joined to the opposite ends of the central portion 68 and terminate in axially aligned, out-turned end portions 74 which are respectively received in blind bore receptacles 76 provided in the inner surfaces of the housing side walls 18 and 20. The dog-leg shaped portions 72 at the ends of the central portion 68 of the rod 66 are located to pass closely alongside the brackets 70 to thus restrict movement of the cover 38 along the rod portion 68. Also, it is to be noted that when the cover 38 is in its operative position the skirts 44 cooperate with the side walls 18 and 20 to prevent access to the hinge rod 66 so that a tool may not be used to disengage the rod 66 from the receptacles 76. In this regard it should be noted that one or both of the flanges 44 could be omitted if the height of one or both of the side walls were increased.
The cover 38 is releasably retained in its stored position by means of a ball stud 78 threadedly fixed to the lower housing wall 16. The lock tab back-up plate 64 of the cover 38 also serves as a support for a spring metal clip 80, which is perforated so as to form a resiliently expandable receptacle sized smaller than the outer end of the ball stud 78 but being expandable to receive the same so as to retain the cover in its stored position as shown in dashed lines in FIG. 3.
The operation of the invention is briefly as follows. Assuming the cover 38 to be in its operative position, shown in solid lines in FIG. 3, wherein it blocks access to the instruments carried by the lower panel section 26, it will be releasably retained in place through the co-action of the locking tab 54 and locking rod 58 of the key-operable lock mechanism and through the co-action of the cover tabs 48 and the tab receptacles 50. Further, it is to be noted that added integrity is given to the effectiveness of the lock mechanism due to the fact that the back-up plate 64 acts to support the free end of the locking tab 54.
To move the cover 38 from its operative to its stored position, the operator initially needs to insert a key in the lock 52 and rotate the tab 54 from beneath the angled end 56 of the locking rod 58. Once this is done, the tabs 48 can be released from the receptacles 50 by pivoting the cover 38 upwardly about the center portion 68 of the hinge rod 66. The cover 38 and rod 66 are then pivoted downwardly together about the pivot axis defined by the out-turned ends 74 of the rod. By virtue of the dog-leg shaped portions 72 of the rod 66, the cover 38 is guided to its stored position against the lower housing wall 16 with the receptacle of the clip 80 then being received on the outer end of the ball stud 78 so as to retain the cover 38 in its stored position.
It is of significance that the hinge rod 66 may be easily installed in the console housing 12 by merely inserting the left end (FIGS. 1 and 2) of the rod 66 in the left blind bore receptacle 76 and then by deflecting the rod 66 sufficiently to permit entry of its right end in the right blind bore receptacle. The rod 66 is made of such size and material that during installation it will not be flexed beyond its elastic limit and will therefore return to its unflexed state so as to securely engage the receptacles 76. This mounting of the hinge rod 66 contributes to the fact that the rod is completely hidden when the cover 38 is in its operative position.
