A still further object of the inventionis to provide an improved manual control device adaptable for use with a wide range of mechanisms or systems such as for use an input device'for a digital computer or for any other machine or system requiring rapid and definite communication between the; operator and the system in the form of hand or finger movements.

A still furthergobject of the invention is to' provide an improved touch-activated control device for multi-function machines or systems, the device being applicable for use with computing machines, such as adding machines, bookk eping machines, calculators, and cash registers, and being likewise applicable for use with a wide range of other mechanisms or systems wherein the input symbols or commands may or may not be of an arithmetic nature, the improved device being operated by simple but precise movements of the operators hand or fingers, the required movements being easy to learn and being unambiguous in nature.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

FIGURE 1 is a perspective view of a typical manual control device constructed in accordance with the present invention.

FIGURE 2 is a top plan view, to an enlarged scale, of the manual control device shown in FIGURE 1.

FIGURE 3 is a front elevational view of the manual control device shown in FIGURE 2.

' FIGURE 4 is a longitudinal vertical cross-sectional view taken through the manual control device substantially on the line 44 of FIGURE 2.

Referring to the drawings, the typical embodiment of a manual control device according to this invention shown in FIGURE 1 is designated generally at 11. The device 11 comprises a generally rectangular housing 12 which is open at its front and top and which thus consists of the parallel vertical side walls 13 and 14, the horizontal bottom wall 15 and the upstanding transverse vertical rear wall 16. The enclosure thus defined is of sufiicient size to comfortably receive a hand, shown in dotted view at 17 in FIGURE 4, with ample clearance for horizontal, vertical or longitudinal movements of the hand.

Designated at 18 is a transversely extending handle member of inverted U-shape having the hollow horizontal cross arm portion 19 and the depending vertical legs 20 and 21. The legs 20 and 21 are respectively secured rigidly to the outer surfaces of the side walls 14 and 13. The transversely extending handle member 18 18 located in a transverse vertical plane spaced forwardly from the transverse median vertical plane of the housing 12 and located approximately one-third of the distance from the front vertical plane of said housing to the rear wall 16. The respective vertical walls 13, 14 and 16 may be of hollow construction, for a purpose presently to be described. The bottom wall 15 may likewise be of hollow construction. Mounted on the forward portion of the bottom wall 15 in a position easily accessible to the fingers of the users hand 17 is a standard keyboard assembly 22, said keyboard assembly being located more closely adjacent to the side wall 14 than the side wall 13, for a right-handed operator, as shown in FIGURE 2. The placement of the unit 22 for a left-handed operator would, of course, be more closely adjacent to the side wall 13 than the side wall 14. The keyboard unit 22 comprises vertically movable depressible buttons 23, for example, nine buttons numbered 1 to 9, adapted to be selectively operated by the fingers of the users hand, a tenth depressible button 24 spaced laterally from the buttons 23, as shown in FIG- URE 2, and adapted to be operated by the users thumb. The buttons 23 and 24 on the keyboard assembly 22 may be similar to those found on conventional adding machines, cash registers, or the like.

Designated at 25 is an additional push button member which is mounted on the rear wall 16 in the path of forward movement of the operators hand 17 when the hand is positioned over the keyboard 22, so that the push button element 25 may be actuated by the users knuckles by moving the hand forwardly. The push button element 25 may be the operating member of the control switch 26 mounted in the hollow rear wall 16, as shown in FIGURE 4, so that the switch 26 is operated responsive to the force exerted on the button element 25.

Mounted on the forward portion of side wall 13 substantially in the same horizontal plane as the push button element 25 is another push button element 27 adapted to be operated responsive to lateral movement of the operating hand 17 to the right, as viewed in FIGURES 2 and 3. The push button element 27 operatively controls a switch similar to the switch 26, or similar system-com trolling element. Mounted in a similar manner on the side wall 14 in the same horizontal plane as the push button elements 25 and 27 and substantially transversely aligned with the push button element 27 is a third additional push button element 28 located so as to be actuated responsive to movements of the hand 17 to the left, as viewed in FIGURES 2 and 3. The push button element 28 is likewise associated with a suitable switch or other equivalent control assembly mounted in the hollow side wall 14.

Mounted on the bottom wall 15 substantially in the transverse vertical plane of push button elements 28 and 27 is an upstanding push button element 29 located in a position to be engaged by the palm of the operators hand 17 and to be actuated responsive to downward movement of the hand. The push button element 29 is operatively associated with a switch or equivalent system-controlling mechanism mounted in the hollow bottom wall 15.

As shown in FIGURE 4, the three push button elements 27, 28 and 29 are preferably located in substantially the same transverse vertical plane, said transverse vertical plane being spaced forwardly from the transverse vertical plane of the handle member 18 and being located approximately adjacent to the heel portion of the operators hand 17 when the hand is arranged in operating relationship to the keyboard assembly 22, as shown in FIGURES 2 and 4. Thus, the side buttons 27 and 28 may be operatively engaged by the side edges of the users hand by lateral movements of the hand, whereas the bottom button element 29 may be actuated by simply moving the hand or wrist downwardly while it is in its normal operating position.

Mounted on the bottom surface of the hollow transverse cross bar I19 substantially in the same longitudinal vertical plane as the push button elements 29 and 25 is a depending further push button element 30 which is located over the upper knuckle joint portion of the users hand in a position to be engaged responsive to upward movement of the users hand while it is in its normal operating position, shown in dotted view in FIGURE 4. The push button element 30 is operatively associated with a switch assembly 131 provided in the hollow cross bar 19, so that the switch is actuated responsive to the upward force exerted on the push button element 30 as the operator raises his hand 217 to engage the push button.

It will thus be seen that when the operator has his hand 17 positioned in the enclosure or shell defined by the housing 12, and in the space defined within the push button elements 27, 29, 28, 30 and 25, with his fingers located over the keyboard 22, the users fingers are positioned so that they can selectively actuate any one of the keys 23 or the thumb key 24, providing a selection of ten ditferent inputs or commands by the fingers, and the users hand can furnish any one of five additional inputs or commands by moving the hand in any one of five different directions, namely, forwardly, laterally to the left, laterally to the right, downwardly or upwardly. Thus, if the control device is employed in connection with an arithmetical computing machine, the control device 11 may be used to furnish numerical inputs, employing keys 2'3 and 24, and can also be used to command specific arithmetical operations such as add, subtract, multiply, divide, and subtotal or total. Similarly, the auxiliary control elements may be employed in the case of a cash register to identify item-s, departments, or to insert other data pertinent to the particular function of the system with which the control device is employed.

As will be readily apparent, the control device is applicable not only to computing or calculating machines and registers such as adding machines, bookkeeping machines, calculators and cash registers, but is also applicable to a wide range of other mechanisms which require various types of input commands or orders, for example, complex machine tools, vehicles, conveyors, or other automated equipment.

While the specific embodiment illustrated herein utilizes only five auxiliary control elements, corresponding to five simple hand movements, it will be readily apparent that any number of control elements may be employed corresponding to additional possible hand movements. For example, controls may be included for inclined or oblique hand movements as well as simple vertical or lateral hand movements. Thus, a substantial number of control elements may be incorporated in the device as required for different applications of the device. Different movements of the whole hand serve to operate the respective different control elements, in addition to the specific digital control inputs afforded by the use of the ten-key finger board assembly 22.

As will be readily apparent, the operators hand 17 is surrounded by the control device 11 so that communication between the operator and the associated mechanism or system being controlled is simple and direct, being affected by specific movements of the operators hand 17 or its fingers. The input commands are thus direct and unambiguous, and involve relatively simple hand and finger movements. For this reason, the use of the control device may be readily and quickly taught to an operator. Because of the fact that the hand is surrounded by the control elements, the required movements of the hand are relatively easy and the input commands can be transmitted efficiently with minimum exertion or fatigue on the part of the operator.

As will be readily apparent, in the typical embodiment of the invention illustrated herein, input data may be transmitted to a digital computing device by means of the control assembly of the present invention whenever the data may be represented by fifteen symbols or commands or less. Of course, when additional controls for corresponding additional directional hand movements are employed, the number of input symbols or commands may be correspondingly increased.

The various electrical wires connected to the switches operated by the push button elements of the device -11 are housed in a suitable cable 40 leading to the associated control apparatus.

While a specific embodiment of an improved manual control device has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
