United States Patent "ice 3,332,648 CONTROL DEVICE MOUNTING Eric P. Selinder, San Pedro, Calif, assignor to Honeywell Inc., Minneapolis, Minn a corporation of Delaware Filed Aug. 16, 1965, Ser. No. 479,851 4 Claims. (Cl. 248-27) ABSTRACT OF THE DISCLOSURE A mounting arrangement for a control device, particularly one that can be snapped into place, requiring no separate fastening means.
In the presently preferred embodiment of the invention a thermostat is mounted on the sheet metal housing of a space heater by means of cooperating portions of the thermostat frame and of a panel forming part of the housing. Portions of the mounting means also cooperate with adjusting means for the thermostat to indicate the setting selected and to limit movement of the adjusting means.
In the drawing:
FIGURE 1 shows a control point adjusting dial for a control device together with a cooperating pointer extending through a panel, 7
FIGURE 2 is a view similar to FIGURE 1 but with the dial removed.
FIGURE 3 is a side view of the device shown in FIG- URE 1, and
FIGURE 4 is aside view of the device in a position preliminary to attachment to the panel.
As seen in the drawing, a panel may be part of an enclosure for a gas fired space heater. A thermostat 11 having a rectangular housing 12 is mounted on the panel 10 in a position where an adjusting knob 14 will be accessible from outside the enclosure. The invention lies in the arrangement for fastening the thermostat to the panel.
The thermostat housing is provided with a mounting bracket 16 having a flat central portion 17 spaced from and parallel to a flat surface of the housing, and offset end portions 18 and 19 lying along the fiat surface of the housing. The flat central portion 17 is held against the panel 10 in part by two ears 21 and 22 struck up from an intermediate part of the bracket, and in part by a finger 25 struck up from the bracket 16 beyond its end portion 19.
The thermostat 11 has an adjusting shaft 27 which extends from housing 12 and through an opening 28 in the bracket 16. The opening 28 has an upper portion 28a that is concentric with the shaft 27 and a lower portion 28b from which the material for ears 21 and 22 was punched.
The ears 21 and 22 extend radially with respect to the adjusting shaft 27 and are notched at their outer edges to hook on the panel 10 at the edge of a circular hole 30. Conveniently, the hole 30 is concentric with the adjusting shaft 27 and has a diameter greater than the distance between the outer extremities of ears 21 and 22 to facilitate mounting the thermostat on the panel.
The finger 25 which extends from the upper end of bracket 16 engages an edge of panel 10 formed by the upper edge of a circular hole 34. Part of the upper surface of the finger 25 has a cylindrical surface that conforms to the hole 34, but a raised detent 25a is provided on the finger to engage the outer edge of the hole to hold the bracket in position against the panel. The finger 25 also extends outwardly beyond the detent portions 25a and is tapered to form a pointer 25b that serves as anindex to cooperate with indicia on the knob 14 which is carried on the adjusting shaft 27.
FIGURE 4 shows how the thermostat is attached to the just enter the hole 34. To move the thermostat counterclockwise with the ears 21 and 22 fixing the pivotal axis,
the finger 25 is deflected to permit the detent portion 25a to pass to the outer side of the panel. The finger 25 is sufiiciently resilient to assume the position shown in FIG- URE 3 after being forced into engagement with the panel.
The adjusting shaft 27 is generally cylindrical but has a flat surface 27a at its outer end to prevent rotation of the knob 36 with respect to the shaft. Also carried on the shaft 27 is snap ring 38 that is hooked onto the flat portion of the shaft and has a radial abutment portion 38a adapted to cooperate with the ears 21 and 22 to limit rotation of adjusting shaft 27 and knob 14 to the desired range for adjustment of the thermostat, as shown in FIGURE 2.
It will be seen that the construction illustrated provides a thermostat mounting that is both inexpensive and Very convenient in use in that no tools or loose fastening means are needed. The configuration of the mounting bracket not only spaces the thermostat from the mounting panel to provide good air circulation but permits the thermostat'to be tilted with respect to the panel during the mounting procedure. Additionally, this spacing permits the upper mounting finger to have sufficient length to give enough resilience for the deflection necessary to snap the thermostat into place on the panel. The mounting bracket also provides the additional functions of serving as a pointer for the adjusting dial and of providing stops to limit dial rotation.
What is claimed is:
1. A mounting arrangement for a control device comprising: a panel of generally flat configuration having two spaced circular holes therein, a control device having a frame to which mounting means is secured, said mounting means including a spaced pair of hooks shaped to engage the edge of said panel at one of said openings at points spaced equal distances from a line connecting the centers of the holes in said panel, and including a resilient finger having. a detent portion engaging the edge of said panel at the other of said openings on the line connecting the centers of the holes, and further including a flat abutment surface engaging the panel between the two holes.
2. A mounting arrangement for a control device comprising: a panel of generally fiat configuration having two spaced holes therein one of which is circular, a control device having a frame with mounting means integral therewith, said mounting means including a pair of hooks engaging an edge of said panel defined by the circular hole, and further including a resilient finger having a detent portion engaging an edge of said panel within the other hole, said two hooks being equally spaced from said finger, said control device having an adjusti'hg shaft extending therefrom through the circular hole in said panel, and an abutment on said shaft cooperating with said hooks to limit rotation of said shaft.
3. A mounting arrangement for a control device comprising: a panel of generally flat configuration having two spaced holes therein one of which is circular, a control device having a frame with mounting means integral therewith, said mounting means including a pair of hooks engaging an edge of said panel defined by the circular hole, and further including a resilient finger having a detent portion engaging an edge of said panel within the other hole, said two books being equally spaced from said finger, said control device having an adjusting shaft extending therefrom through the circular hole in said panel, a dial on said shaft having indicia thereon, cooperating with said finger acting as an index.
