MOUNTING BRACKET FOR TRIMMER POTENTIOMETERS OR THE LIKE Filed July 11, 1963 INV EN TOR. P41 410 6 P007 United States Patent Nebr., assignor to Dale Nebr., a corporation of Trimmer potentiometers and related components are normally secured to a chassis deck in their operational environments by means of an auxiliary mounting bracket. These mounting brackets often have movable components which must be manipulated to secure a trimmer potentiometer therein. These movable components add to the expense of the brackets and are sometimes tedious to actuate. Since potentiometer housing and the like vary in design, these brackets sometimes serve to interfere with the external electrical leads of the unit.
' Therefore, a principal object of this invention is to provide a mounting bracket for trimmer potentiometers or the like which can grasp a potentiometer housing without actuating any movable parts and which will not interfere with the external electrical leads of the potentiometer.
A still further object of this invention is to provide such a mounting bracket which requires no mounting holes in the potentiometer, but which effects its grasp on the potentiometer housing by interlocking itself on interlocking surfaces on the housing.
A still further object of this invention is to provide a mounting bracket for trimmer potentiometers or the like that can accommodate and hold a plurality of potentiometer units.
Still further objects of this invention are to provide a mounting bracket for trimmer potentiometers or the like that is economical in manufacture, durable in use, and refined in appearance.
These and other objects will be apparent to those skilled in the art.
This invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in the claims, and illustrated in the accompanying drawing, in which:
FIGURE 1 is a perspective view of the potentiometer housing used in conjunction with the mounting bracket of this invention;
FIGURE 2 is a perspective view of the mounting bracket of this invention;
FIGURE 3 is a perspective view of an alternate form of mounting bracket;
FIGURE 4 is the top plan view of a potentiometer housing mounted in one of the mounting brackets of FIGURE 2 or 3;
FIGURE 5 is a side elevational view of the potentiometer of FIGURE I mounted in the mounting bracket 'of FIGURE 2; and
FIGURE 6 is an oblique elevational view of three p0- tentiometers of the type shown in FIGURE I mounted in the mounting bracket of FIGURE 3.
The numeral 10 generally designates a supporting deck upon which the mounting brackets normally would be secured. A potentiometer housing 12 is generally rectangular in shape and includes ends 14, sides 16, top 18 and bottom 20. Two diagonally opposite corner portions 22 and 24 include vertical diagonally disposed surfaces 26 and 28, respectively, which dwell in a plane disposed at approximately a 45 degree angle with respect to the planes of the ends 14 and sides 16. Inwardly extending arcuate indentations 30 appear in the center of each of 2 the diagonally disposed surfaces 26 and 28. The potentiometer housing includes the customary leads 32 extending from one end thereof with a horizontall disposed leadscrew 34 rotatably mounted therein.
A mounting bracket 36 includes a center horizontal bar portion 38 which has a length substantially equal to the distance between the two diagonally disposed surfaces 26 and 2S. Apertures 40 are located in spaced relation on bar portion 38 to receive nut and bolt assemblies 41 which are used to effect the connection of the mounting bracket 36 to the supporting deck 10. Vertical upstanding end portions 42 and 44 extend upwardly in parallel fashion from the opposite ends of the center bar portion 38. It will be noted that the planes of upstanding end portions 42 and 44 are disposed at an oblique angle with respect to the longitudinal axis of the center bar portion 38. Inwardly extending lips 46 protrude from the upper ends of the upstanding end portions 42 and 44. Inwardly extending indentations 48, which are complementary in shape to the arcuate indentations 30 in the diagonally disposed surfaces 26 and 28, appear in each of the upstanding end portions 42 and 44.
An alternate form of mounting bracket 36 is shown by the mounting bracket 50 in FIGURE 3. Upstanding end portions 42A and 44A of mounting bracket 50 are similar to the upstanding portions 42 and 44, respectively, of mounting bracket 36 except that the end portions 42 and 44 have a greater vertical height. In addition, instead of having only one inwardly extending indentation 48 as was found in the upwardly end portions 42 and 44 in mounting bracket 36, the end portions 42A and 44A of mounting bracket 50 have a plurality of inwardly extending indentations 48A, 48B and 48C. The indentations in each upstanding end portion are similarly positioned.
It is preferred that each of the mounting brackets 36 and 5% have some resilient characteristics and are preferably made of a single piece of material.
After the bracket 36 has been secured to the deck 10 in the manner described, the potentiometer housing 12 can be inserted in a diagonal direction with respect to the mounting bracket so that the diagonally disposed surfaces 26 and 28 of the housing register with the upstanding ends 42 and 44, respectively, of the mounting bracket. As the housing 12 is being moved into this position, the indentations 48 in the upstanding ends 42 and 44 of the mounting bracket will engage the surfaces 26 and 28 of the housing and cause the upstanding ends to momentarily be forced outwardly. However, as soon as the indentations 30 in the surfaces 26 and 2S register with the indentations 48 in the upstanding ends 42 and 44, the upstanding ends will snap back to their normal vertical position as the indentations 48 move into the indentations 39 of the housing. Thus, the potentiometer housing 12 can be easily and quickly inserted in the mounting bracket 36 and its removal therefrom can be effected by merely reversing the above described process.
The mounting bracket 50 is utilized in the same manner as the bracket 36, except that a plurality of potentiometers can be secured therein by virtue of the extended 7 length of the upstanding ends of the bracket and the pluraiity of indentations in each upstanding end. It will be noted that the spacing between the indentations 43A,
83 and 48C in mounting bracket 50 is such that potentiometers mounted between the upstanding ends will rest one upon the other.
The elimination of mounting holes in the potentiometer housing will permit more room within the housing for component mechanisms, thereby permitting miniaturization of the unit, or allowing a longer mandrel for better resolution and higher values per case size. Such elimination also alleviates terminal disfiguration when the leads extend through the housing end, thereby permitting simplicity of design and alleviating some housing sealing problems.
From the foregoing, it is seen that this invention will accomplish at least all of its stated objectives. 7
Some changes may be made in the construction and arrangement of my mounting bracket for trimmer potentiometers or the like without departing from the real spirit and purpose of my. invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
