## Background
FIELD
The present invention relates generally to keypads. More particularly, the present invention relates to an improved mounting structure for keypads.
BACKGROUND
Currently, keypads are mounted on a mounting structure, such as a bracket, for affixing the keypad to the wall. However, known mounting structures have several disadvantages. First, known mounting structures are exposed or visible from a side view, which can be undesirable in terms of appearance and aesthetics. Furthermore, known mounting structures require the keypad to include many installation openings for mounting the keypad to the mounting structure. This can be a competitive disadvantage when vying for sales volume in the marketplace. Finally, known mounting structures, such as a bracket, increase the overall product thickness. This can be undesirable because an increased thickness causes the keypad to be increasingly displaced from a wall to which the keypad, via the mounting structure, is affixed.
FIGS. 1A-1F are views of a keypad and mounting structure known in the art. As seen in FIG. 1A, the keypad 100 includes a plurality of installation openings 110, for example, apertures or indentations, for mounting the keypad 100 to a mounting structure, for example, the bracket 120 shown in FIG. 1B. The bracket 120 includes a plurality of protrusions 130, which can be inserted into respective ones of the plurality of installation openings 110 in the keypad 100 to affix the bracket 120 to the keypad 100. The bracket 120 can be affixed to a wall as would be known by those of ordinary skill in the art.
FIG. 1C is a phantom view and FIG. 1D is a perspective view of the bracket 120 affixed to the keypad 100. However, as seen in the cross-sectional view of FIG. 1E and the side view of FIG. 1F, even when the protrusions 130 of the bracket 120 are inserted into the openings 110 of the keypad 100 for affixing the bracket 120 to the keypad 100, a portion of the bracket 120 is exposed, visible, and adds an increased thickness to the structure. This is undesirable.
In view of the above, there is a continuing, ongoing need for an improved mounting structure for keypads.

DETAILED DESCRIPTION
While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.
Embodiments disclosed herein include an improved mounting structure for keypads. For example, in some embodiments, the improved mounting structure disclosed herein can eliminate a mounting bracket that is exposed or visible from a side view. In some embodiments, the improved mounting structure disclosed herein can eliminate the need for installation openings in the keypad. Further, in some embodiments, the improved mounting structure disclosed herein can reduce and/or substantially eliminate the added product thickness caused by known mounting brackets. For example, in some embodiments, product thickness can be reduced by as much as approximately 2 mm.
FIG. 2A is a perspective view of an improved mounting structure 200 in accordance with disclosed embodiments. As seen in FIG. 2A, the mounting structure 200 can include first and second parallel frame members 210, 220 and first and second parallel spring-loaded members 230, 240. For example, in some embodiments each of the members 230, 240, can include first and second socket members 232 coupled to one another via a spring 234. In some embodiments, the socket members and the spring can be enclosed in a housing 236, for example, a housing 236 that defines a channel along which the socket members 232 and the springs 234 can slide.
Respective first and second ends of each of the first and second parallel frame members 210, 220 can be coupled to one another via respective ones of the first and second parallel spring-loaded members 230, 240, for example, respective ones of the socket members 232. Further, each of the frame members 210, 220 can include a plurality of mounting devices 215, such as, for example, a protrusion, hook, or the like, that can be used to attach, affix, or associate the mounting structure 200 to a keypad or a keypad case. In some embodiments, each of the mounting devices 215 can include an inclined hook.
Respective first and second affixation mechanisms 250, 260 can be attached to, associated with, and/or integral with respective ones of the members 230, 240 along the lengths thereof. For example, as seen in FIG. 2B, each of the affixation mechanisms 250, 260 can include an aperture or the like for receiving an affixation device, such as a screw, bolt, or the like, which can be used to secure the mechanism 250, 260, and thereby the mounting structure 200, to a second device or apparatus, such as a gangbox. In some embodiments, a washer can also be used in connection with the affixation mechanisms 250, 260 and the affixation device.
As seen in FIG. 2C, a device or apparatus, such as a gangbox 300, can be disposed in a wall or other structure as would be known by those of skill in the art. The mounting structure 200 in accordance with disclosed embodiments can be affixed to, attached to, and/or associated with the gangbox 300 via the affixation mechanisms 250, 260 and respective affixation devices. For example, as best seen in the cross-sectional view of FIG. 2D, in some embodiments, the gangbox 300 can include corresponding affixation mechanisms 310, 320 for affixing to, attaching to, and/or associating with respective ones of the affixation mechanisms 250, 260 and affixation devices.
The combination of the frame members 210, 220 and the spring-loaded members 230, 240 can form the mounting structure 200, which can include a spring frame. In some embodiments, the width W of the structure 200 can be fixed. However, in some embodiments, the length L of the structure 200 can be adjustable. For example, as best seen in the cross-sectional view of FIG. 2E, the length L of the structure 200 can be adjusted by compressing or releasing the spring 234 associated with each of the members 230, 240, thereby changing the length of each of the members 230, 240. In some embodiments, the force or pressure from the gangbox 300 or an associated keypad or keypad case, via the mounting devices 215, can cause the spring 234 associated with each of the members 230, 240 to compress.
When the mounting structure 200 is affixed to, attached to, and/or associated with the gangbox 300 as disclosed herein, the majority of the structure 200 can be disposed within the gangbox 300 so as not to protrude outside of the gangbox 300 and thereby, so as not to protrude outside of the wall. For example, in some embodiments, substantially all of the mounting structure 200 can be disposed within the gangbox 300. In some embodiments, the only portion of the mounting structure 200 that protrudes outside of the gangbox 300 can include the plurality of mounting devices 215.
FIG. 2F is a back perspective view of a keypad 400 affixed to a mounting structure 200 in accordance with one disclosed embodiment, and FIG. 2G is a back perspective view of a keypad case 500 affixed to a mounting structure 200 in accordance with one disclosed embodiment. The gangbox 300 is shown in phantom in both FIG. 2F and FIG. 2G. However, as seen, when the keypad 400 or the keypad case 500 is affixed to, attached to, and/or associated with the mounting structure 200 via the plurality of mounting devices 215, substantially no part of the mounting structure 200 is exposed or visible from a side view. That is, substantially all of the mounting structure 200 can be hidden from view by the gangbox 300, the wall, and/or the keypad 400 or the keypad case 500.
In some embodiments, the only portion of the mounting structure 200 that extends outside of the gangbox 300 can include the mounting devices 215. For example, FIG. 2H is a front perspective view of the keypad case 500 affixed to the mounting structure 200 and illustrates the mounting devices 215 protruding outside of the gangbox 300. However, as also seen in FIG. 2H, the keypad case 500 can hide the protruding mounting devices 215 from a side view of the case 500.
In accordance with the above, in some embodiments, the mounting structure 200 does not add any thickness to the keypad 400 or keypad case 500 or cause the keypad 400 or keypad case 500 to protrude from the wall any further than the thickness of the keypad 400 itself or the keypad case 500 itself. In some embodiments, because the mounting structure 200 includes a plurality of mounting devices 215, neither the keypad 400 nor the keypad case 500 needs to include openings for affixing to, attaching to, and/or associating with the mounting devices 215 and thereby, the mounting structure 200.
Although a few embodiments have been described in detail above, other modifications are possible. For example, the logic flows described above do not require the particular order described, or sequential order, to achieve desirable results. Other steps may be provided, or steps may be eliminated, from the described flows, and other components may be added to, or removed from, the described systems. Other embodiments may be within the scope of the invention.
From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific system or method described herein is intended or should be inferred. It is, of course, intended to cover all such modifications as fall within the sprit and scope of the invention.
