Hatcher 2-The above objects and other objects of this invention are accomplished by providing a support having upper and lower pivotally interconnected units, the lower unit carrying a belt so that it may be belted to the car seat, and the upper unit in turn carrying a belt for the purpose of securing the lap top computer to the upper unit. In order to provide for suitable adjustment of the computer for ease of viewing and use, the lower unit is provided with a pair of opposed downwardly extending legs, one of which legs may be secured in various positions of vertical adjustment. The upper and lower units, which are pivotally interconnected to each other for swiveling movement of the upper unit with respect to the lower unit, are provided with means to secure the upper unit in various posi-tions of swiveling adjustment. In addition, the upper unit is pro-vided with a vertically adjustable auxiliary support so that the angle of inclination of the lap type computer may be varied.
The foregoing will become more apparent after a consideration of the following detailed description taken in conjunction with the accompanying drawings in which a preferred form of this invention is illustrated.

Detailed Description -With reference to the drawings, the support of this invention is indicated generally at 10. As shown in Figure 1, the support is shown mounted on a car seat 12, a portable or lap top co~puter, indicated generally a~ 14, being mounted thereon. This type of computer is typically provided with a rigid base 16 which extends the length of the computer, a forward portion of the base being provided with a keyboard 18. Hinged to the base is a keyboard cover 20 which is provided with an LCD screen 22. This form of computer constrùction is well-known in the art. Such computers today typi-cally have 512K or more Random Access Memory (RAM) and either one or two disk drives. When used by a route salesman, a disk is frequent-ly loaded with customer data base information and the route salesman can access this information prior to visiting a customer, and this information can be updated after the route salesman's call, in addi-tion to the route salesman entering orders. Therefore, as pointed out above, it is desirable that the computer be mounted in the car for ready access by the user of the computer or route salesman.
Referring now in greater detail Figures 2 to 4, the support of this invention conslst of a number of major components, these being a lower unit, indicated generally at 30, and an upper unit, indi-cated generally at 32, which is moun~ed upon the lower unit by pivot means, indicated generally at ~4 in Fig. 4, ~or adjustable swiveling , . . : .

positioning. Mounted upon the upper unit is a vertically adjustable auxiliary support, indicated generally at 36. In addition to these major components, first and second holding means are provided to hold the lower unit 30 to the car seat 12, and to hold the computer base 16 to the upper unit 32, respectively.
As can best be seen from Figure 3 the lower unit includes an upper intermediate planar portion 40 formed of sheet metal or the like and a pair of downwardly extending legs. The front leg 42 is preferably formed integrally with the portion 40 and includes a vertical portion 42.1 and a lower rearwardly extending flange por-tion or foot portion 42.2 which is adapted to rest upon a front edge of the car seat 12. The rear leg 44, 4~ is vertically adjustable and is therefore ~ormed of separate components. Thus, the upper portion of the rear leg is a vertically extending member 44 which is formed integrally with the upper intermediate planar portion 40.
The lower portion 46 of the rear leg is also formed of sheet metal or the like and includes a vertical portion 46.1 and a foot portion 46.2. In order to provide for vertical adjustment of the rear leg 44, 46 the upper portion is provided with a pair of spaced apart vertical slots 48. In addition, the vertical portion 46.1 of the lower portion of the rear leg is provided with a pair of apertures (no number) which are adapted to be positioned in alignment with the slots 48, fastener receiving means in the ~orm of weld nuts 50 being secured to the portion 46.1 about the apertures. Threaded fasteners 52 are adapted to be passed through the slots 48 and secured within the fastener receiving means 50 to secure the parts together, the threaded fasteners having enlarged knurled heads which can be easily engaged by hand. As can best be seen from Figure 4 the back of a seat in a car is typically disposed at a lower position than tile front of the seat, and the angle may vary from car to car.

Therefore it is necessary in order to properly position the computer for use by the operator that the rear leg be adjustable.
First holding means is provided for holding the lower unit 30 onto the seat 12, which first holding means consists of a belt 54, which belt is adapted to be passed through front and rear horizontal slots ~6, 58, in portions 42.1 and 46.1, respectively. The belt 54 may be a nylon strap. In any event~ the ends o~ the belt are pro-vided with suitable fastening means or buckling means 60 so that the ends of the belt can be secured to each other with the belt firmly disposed about the car seat.
The upper unit 32 includes a lower intermediate planar portion 6Z and a pair of opposed upwardly extending legs, the front leg being indicated at 64 and the rear leg at 66. As can best be seen from Figure 1 the width of the planar portion 62 between the legs 64 and 66 is of such a width that the base 16 of the lap top computer may be confined between the legs. The upper unit 32, like the lower unit 30 is typically formed from essentially a single piece of sheet metal which is bent into the desired configuration.
The pivot means 34 consists essentially of a threaded fastener 68 having an enlarged head which can be manually engaged, which threaded fastener is adapted to be passed through a suitable aper-ture 70 in the lower intermediate port~on 62 of the upper unit, and then through an aperture (no number) in the upper intermediate planar portion 40 of the lower unit 30, the threaded fastener being received by fastener receiving means in the ~orm of a weld nut 72 secured about the aperture in the lower unit. As the upper unit will be moved between a position wherein the legs are parallel to the seat back to an alternate position shown in broken lines in Figure 2, it is des~rable that the pivot means be positioned " -~

.

Hatcher -6-relatively close to the operator so that the back of the upper unit 32 does not contact the seat back as the unit is moved to its various positions of adjustment. Thus, the pivot means is disposed adjacent that edge of the lower unit which is adapted to be posi-tioned closest to the user.
In order to hold the upper unit on the lower unit in various positions of swivel adjustment an arcuate slot 74 is formed on the upper intermediate planar portion 40 of the lower unit, and an aper-ture 76 is formed on the lower intermediate portion 62 of the upper unit 32, which aperture 76 is adapted to be placed in register with the siot 74. A screw 78 is adapted to extend through the aperture 76 and slot 74 and be held by a nut 80. If the lap top computer is not in the proper position for use by the operator, it is only necessary for him to loosen nut 80 and to reposition the upper unit on the lower unit until it is in the desired operating position, at which time he would then retighten nut 80. While a slotted head screw 78 is shown, it should be obvious that this could be replaced by a carriage bolt or any other suitable fastener.
The vertically adjustable auxiliary support means ~6 consists essentiall,y of a rod 82. The ends of the rod 82 are threaded and are adapted to receive nuts 84. The rod 82 is disposed in varying positions of vertical adjustment by positioning it in vertically aligned apertures 86, which apertures are disposed at that end of the ~ront and rear legs 64, 66 which is closest to the computer operator. As can be seen from Figure 1 a lower forward portion of the computer base 16 is adapted to rest upon the rod. In order to protect the base from being scratched and to improve the frictional coefficient between the auxiliary support 36 and the base of the computer, the rod is covered with a soft tube 88 of vinyl, rubber or the like.

i . .

1 32g293 Hatcher -7-In order to secure the computer base to the upper unit 32 each of the legs 64, 66 is provided with a pair of spaced apart parallel horizontally extending slots 90. Second holding ~eans in the form of a belt or strap 92 is adapted to be passed through the slots as best indicated in Figure 3, the belt 92 being provided with a buckle 94 of conventional design. The particular buckle shown is o~ the type sold under the model designation "FASTEX #SRI" by ITW Nexus, and covered by U.S. patents 4,150,464 and 4,171,555. While this type of buckle or fastener is desirable, other forms of buckles may also be employed.
The support of this invention is utilized by positioning it on a seat in the manner shown, securing the lower unit 30 by means of lower belt or strap 54. In addition, a seat belt may also be passed underneath the lower unit to secure the rear leg assembly 44, 46 adjacent the back of the seat, this feature not being illustrated in the drawings. If the angle of the support surface 62 is not cor-rect, the length of the adjustable rear leg 44, 46 will now be ad justed to position the support surface 62 at the correct angle for the operator. The upper unit will now be swiveled to its desired position and secured in place by nut 80. The lap type computer will now be mounted on the unit and if the keyboard is either too low or too high the rod 82 will then be adjusted to place it in the proper position. It is now only necessary to strap the computer in place.
While the support of this invention shown in the accompanying drawings and described above has been designed primarily for use with a lap top computer, it should be obvious that the support of this invention can be used for other purposes. Thus, a clip board or equivalent attachment may be provided which can be secured to the upper unit, the support being adjustable so that attachment can be positioned to provide a proper writing surface for the user.
