- ABSTRACT A control mechanism is disclosed embodying a pivot shaft which controls the supply of power to an electric motor, such as utilized for rotating revolving searchlights.
- a universal pivotal mounting arrangement is provided for the pivot shaft which does not require a conventional ball and socket joint. When the shaft is pivoted in one direction, it shifts a free-floating printed circuit board to energize the motor. When the shaft is pivoted in the opposite direction, the printed circuit board effects reversal of the polarity of the input power to the motor.
- the pivot shaft is pivotal about perpendicularly extending axes to control two electric motors simultaneously whereby a Searchlight may be rotated both vertically and horizontally at the same time.
- Control mechanisms utilized for revolving lights or similar rotating devices generally employ a pivot shaft which is commonly referred to in the art as a joy stick. Examples of revolving lights which require such a control mechanism are disclosed in US. Pat. Nos. 2,762,994; 2,578,239; and 3,117,302. In such lights, a single motor is employed for rotating the lights about a vertical axis. More recently, revolving lights have been used which will rotate about both vertical and horizontal axes, thus requiring a pair of electric motors for rotating the lights in this manner. A revolving light of this type is disclosed in U.S. Pat. No. 3,644,728.
- the object of the present invention to overcome the attendant disadvantages of abovementioned control mechanisms by providing a pivot shaft structure which is relatively rugged, yet inexpensive, and which permits simultaneous control of two motors to provide rapid universal positioning of rotatable elements controlled by the motors.
- a control mechanism for rotatable lights or the like including a pivot shaft which normally lies coaxial with a vertical axis and is pivotal in opposite directions about an axis extending perpendicular to the vertical axis to first and second positions.
- a fixed insulative plate carrying a pair of contact elements surrounds the pivot shaft.
- the contact elements are adapted to be connected to an electric motor utilized for rotating the light.
- Each contact element is formed with a contact engaging area.
- a laterally shiftable annular printed circuit board is positioned to surround the pivot shaft and engage the contact elements. This board is provided with spaced inner and outer circular conductive layers which face the contact elements.
- the two layers are adapted to be connected to the positive and negative terminals, respectively, of an electric power supply.
- the contact engaging areas of the contact elements are arranged to lie out of engagement with both the inner and outer conductive layers on the printed circuit board so that no power will flow to the motor.
- the contact engaging area of one of the contact. elements engages the outer conductive layer on the printed circuit board and the contact engaging area of the other contact element engages the inner conductive layer, whereby power will be supplied to the motor to rotate it in one direction.
- the contact engaging area of said one contact element engages the inner conductive layer on the printed circuit board and the contact engaging area of the other contact element engages the outer conductive layer whereby there occurs a reversal of polarity of the power delivered to the motor, thus rotating the motor in the opposite direction.
- the pivot shaft is also pivotal about a second axis perpendicular to the vertical and laterally extending axes so that the pivot shaft is universally pivotal about a central pivot point.
- a second pair of contact elements, connected to a second electric motor are positioned on the insulative plate so as to engage the inner and outer conductive layers on the printed circuit board when the pivot shaft is pivoted about the aforementioned perpendicular axis.
- the pivot shaft is mounted axially within a housing formed with aligned bores of different diameter, defining therebetween a flat annular shoulder.
- An outwardly extending flange is formed on the portion of the shaft lying in the larger diameter bore. This flange is urged into engagement with the annular shoulder by means of a spring, which retains the shaft axially positioned in the bores.
- the diameter of the shaft in the two bores is less than that of the bores so as to permit the shaft to be rocked or pivoted about an axis extending laterally through the axis of the bores near the flange on the shaft.
- This structure is relatively rugged and, therefore, withstands heavy loads. It also permits close and positive positioning of the shaft to thereby provide accurate control of power supplied to the electric motors described in the aforementioned control mechanism.
- FIG. 1 is a schematic illustration of the control mechanism of the present invention showing the relative position of the pivot shaft with respect to a fixed printed circuit board having contact elements thereon adapted to be connected to a pair of electric motors and a movable printed circuit board having conductive layers thereon adapted to be connected to a power supply;
- FIG. 2 is a bottom plan view of the fixed printed circuit board illustrated in FIG. 1 showing how the pair of electric motors are connected to the contact elements on the board;
- FIG. 3 is a fragmentary side view of the board illustrated in FIG. 2 taken along line 3-3, showing the configuration of a contact element on the board;
- FIG. 4 is a top plan view of the movable printed circuit board illustrated in FIG. 1 shown connected to a power supply;
- FIG. 5 is a partial longitudinal sectional view through a preferred form of the pivot shaft structure of the present invention embodied in a control mechanism as illustrated in FIGS. 1-4 with the shaft shown in full lines in its normal position; the pivot shaft and the movable printed circuit board are also shown in phantom in the position these elements would assume when the shaft is pivoted from its normal position about one of its laterally extending pivot axes.
- the control mechanism includes an elongated pivot shaft or joy stick 12 which normally lies coaxial with a vertically extending axis ZZ.
- the shaft 12 is pivotal in opposite directions about an axis X-X which extends perpendicular to and passes through the vertical axis ZZ.
- the shaft is also pivotal in opposite directions about an axis Y-Y which passes through the intersection of the XX and ZZ axes and is perpendicular to both of these axes.
- the shaft 12 is universally pivotal about point 14 which is the point of intersection of the three axes.
- a fixed printed circuit board 16 formed with a central circular opening 17 surrounds the shaft 12 below the pivot point 14.
- the board 16 is positioned so that the center of the opening 17 therein is coaxial with the vertical axis ZZ.
- the printed circuit board 16 comprises an insulative substrate 18 on which there are mounted four contact elements 20, 22, 24, 26.
- each contact element is formed with a downwardly extending resilient arm 28 which is turned up at its end 30 providing therebetween a downwardly facing convex contact engaging area 32.
- the contact elements 24 and 26 are positioned on the substrate 18 so that their respective contact engaging areas 32 lie on an imaginary straight line AA passing through the center of the hole 17 and thus the axis ZZ.
- the contact elements and 22 are positioned on the substrate 18 so that their respective contact engaging areas 32 lie on an imaginary straight line BB which is perpendicular to the line A-A and passes through the intersection of the line A-A and the axis Z-Z.
- the line AA is parallel to the axis XX while the line B-B is parallel to the axis Y-Y.
- the contact engaging areas 32 of the four contact elements are positioned equidistant from the center of the hole 17 and thus lie in a circular path indicated at 34 in FIG. 2 which is coaxial with the vertical axis ZZ.
- Conductive layers 36, 38, 40 and 42 on the lower surface of the substrate 18 extend from the bases of the contact elements 20, 24, 22 and 26, respectively, to an outer peripheral region 44 on the substrate.
- the conductive layers are positioned closely to one another to facilitate the wiring of conductors thereto.
- the conductive layers 36 and 40 are connected to one electric motor Ml while the conductive layers 38 and 42 are connected to a second electric motor M2.
- the printed circuit board 16 constitutes a power takeoff board for delivering electric power to motors M1 and M2.
- a free-floating laterally movable printed circuit board 50 is positioned below the power takeoff board 16.
- the board 50 is free floating since it is not secured to any fixed structure and is free to move in any direction in a horizontal plane.
- the board 50 is in the form of an annular ring having a central circular opening 52 therein which has a diameter greater than that of the shaft 12 but less than that of the opening 17 in the power takeoff board.
- the printed circuit board 50 is normally positioned coaxial with respect to the axis Z-Z.
- the board comprises an insulative plate 51. Continuous inner and outer circular layers 54 and 56, respectively, are formed on the upper surface of the plate so as to face the contact elements mounted on the power takeoff board 16.
- the layer 54 and 56 are spaced radially from one another to provide a nonconductive annular face 58 therebetween.
- a plated through hole 59 is formed through the board 50 at the inner layer 54.
- a radially extending conductive strip 62 on the lower surface of the board 50 extends from the outer periphery 64 of the board to the plated through hole 59.
- the positive terminal of a power supply 66 is connected to the outer conductive layer 56 and the negative terminal of the power supply is connected, as by soldering, to the strip 62 leading to the inner conductive layer 54 through the plated through hole 59, as best seen in FIG. 4.
- the printed circuit board 50 therefore, constitutes the power contact board of the contro mechanism 10.
- the width of the contact engaging areas 32 on the contact elements 20, 22, 24 and 26 is slightly less than the width of the inner and outer conductive layers 54 and 56 and of the nonconductive annular surface 58 therebetween.
- the inner conductive layer 54 on the power contact board 50 will come into engagement with the contact engaging area 32 of the contact element 24 and the outer conductive layer 56 will come into contact with the contact engaging area of the contact element 26 so that current will flow from the power supply 66 through the outer conductive layer 56 to the contact element 26 and from the contact element 26 through the conductive layer 42 on the power takeoff board to one terminal of the motor M2.
- the current will then flow from the other terminal of the motor through the conductive layer 38, contact element 24 and inner conductive layer 54 on the power contact board back to the supply 66, thereby energizing the motor M2 to rotate in one direction.
- the contact element 24 will engage the outer conductive layer 56 on the power contact board and the contact element 26 will engage the inner conductive layer 54, thereby reversing the polarity of the power supplied to the motor M2 and reversing the direction of rotation of the motor. It will be appreciated that when the pivot shaft 12 is pivoted about the axis X--X, the motor M1 will be energized in the same manner as the motor M2.
- the pivot shaft being universally pivotal about both the axes XX and Y-Y, allows not only independent control of the motors M1 and M2 but also simultaneous control of the motors so that a mechanism which is rotatable about both vertical and horizontal axes, for example, can be controlled for movement about both such axes simultaneously. Also, the control mechanism of the present invention permits reversal of the polarity of the power supplied to both the motors.
- FIG. 5 of the drawings shows the preferred form of the pivot shaft mounting arrangement of the present invention embodied in a control mechanism as shown schematically in FIG. 1.
- the shaft 12 includes an upper, relatively small diameter section 70 and a lower, relatively large diameter section 72.
- the pivot shaft is mounted coaxially within a vertically extending bore 74 formed in a support body 76.
- the axis of the bore corresponds to the axis ZZ in FIG. 1.
- the support body is mounted on a face plate 78 by a series of screws 80.
- the bore 74 in the support body includes an upper, relatively small diameter portion 82 and a lower, relatively large diameter portion 84 joined to one another by a flat annular shoulder 86.
- the shoulder 86 lies in a plane which is perpendicular to the axis of the bore 74.
- the diameter of the upper section 70 of the shaft is less than the diameter of the upper portion 82 of the bore and the diameter of the lower section 72 of the shaft is less than that of the lower portion 84 of the bore.
- An annular flange 88 is formed on the lower section 72 of the shaft adjacent to the upper section 70.
- the outer periphery 90 of the flange 88 is spaced slightly from the wall of the bore portion 84 so as to allow the pivot shaft 12 to rock or pivot about a point generally located at the position indicated by reference numeral 91 which lies on the axis of the bore 74.
- the upper, outer edge 92 of the flange is rounded as is the junction of the wall of the lower bore portion 84 and the flat annular shoulder 82 to facilitate rocking action of the shaft 12 within the bore 74.
- the power takeoff board 16 is mounted on the lower surface of the support body 76 by a plurality of screws 96.
- the diameter of the opening 17 in the board 16 is less than that of the lower bore portion 84 so that the inner periphery of the board will extend inwardly from the surface of the bore to define an annular flange 98.
- a generally conically shaped coiled compression spring 100 is positioned in the lower bore portion 84 with the lower, larger diameter end of the spring engaging the flange 9,8 and the upper, smaller diameter end of the spring engaging the flange 88 on the shaft 12.
- the upper surface 101 of the flange 88 is flat and lies in a plane which is perpendicular to the axis of the shaft.
- the compression spring 100 will urge the flat upper surface on the flange 88 into engagement with flat annular shoulder 86 in the support body to normally retain the shaft positioned coaxially within the bore 74.
- the shaft 12 is capable of being pivoted within the support body 76 by exerting a lateral force against the upper section of the shaft.
- the shaft will rock about the pivot point 91 in any direction.
- the point 91 corresponds to the pivot point 14 in FIG. 1.
- the point 91 shifts slightly in the vertical direction in the region of the flange 84 on the shaft due to the arrangement which allows the shaft to make a rocking motion within the support body 76.
- the upper portion 102 of the support body 76 extends through an opening 104 formed in the plate 78.
- a rubber boot seal 106 is engaged with the upper portion 102 of the support body.
- a handle 108 is mounted on the upper section 70 of the shaft. The boot seal is sealed to the lower surface 110 of the handle so that the interior of the support body is protected from the external environment above the plate 78.
- the power contact board 50 is positioned below the power takeoff board 16 and surrounds the lower section 72 of the shaft 12.
- the diameter of the opening 52 in the power contact board is less than the diameter of the opening 17 in the power takeoff board but slightly greater than the diameter of the lower section 72 of the shaft to provide a sliding fit therebetween.
- the insulative plate 51 of the board 50 is chamfered adjacent the opening 52 to form a knife edge which provides a line contact between the board and the lower section 72 of the pivot shaft.
- the line contact permits relatively sensitive and accurate control of the position of the power contact board 50 upon pivoting of the shaft 12.
- a retaining ring 12 is positioned in a groove 114 adjacent the lower end 116 of the shaft 12.
- a generally conical shaped coil compression spring 118 surrounds the lower section 72 of the shaft with the lower, smaller diameter end of the spring engaging the retaining ring 112 and the upper, larger diameter end of the spring engaging the lower surface of the power contact board 50, thereby urging the board upwardly into engagement with the contact engaging areas 32 on the contact elements 20, 22, 24 and 26 mounted on the bottom of the board 16.
- the board 50 is normally positioned so that the contact elements on the board 16 will lie between the inner and outer conductive layers 54 and 56, respectively, on the board 50.
- the pivot shaft 12 is pivoted about the point from the position shown in full lines in FIG. 5 to the position shown in phantom, the board 50 will be shifted in the leftward direction as viewed in FIG. 5 bringing the inner conductive layer 54 on the board 50 into engagement with one contact element 22 and the outer conductive layer 56 into engagement with the diametrically oppositely positioned contact element 20 whereby power will be supplied to the motor M1.
