Abstract

The device of the invention is a seal to close off the spaces between operating devices, such as, buttons and their housing and the spaces between the housing and the cover plate placed over the operating device. The seal has a raised portion into which the operating devices extend so they can be operated from outside the seal. The passage of the seal over the operating device seals operating device/housing spaces. The perimeter of the seal is arranged to engage the housing and cover plate to seal the housing/cover plate spaces.

Claims

1. A splash guard for wiring devices to prevent moisture or debris from entering into or about a wiring device comprising:

a) a wiring device having a front face of a first predetermined periphery, a rear face, two side faces, a top face and a bottom face so assembled as to provide a six-sided enclosure for the operative components of said wiring device, said front face intended to project into an aperture in a cover plate placed over said wiring device;

b) at least one mounting tab, having at least one first aperture through each of said at least one mounting tab, on said wiring device for attaching said device to a support;

c) one or more movable operating means extending through said front face for engagement and operation of said one or more movable operating means by a user;

d) one or more first spaces between each of said one or more movable operating means and said front face of said wiring device, which may permit moisture and debris to enter said enclosure and impede or prevent the proper operation of said wiring device;

e) a cover plate of a second predetermined periphery larger than said first periphery having a from face and a rear face and at least one second aperture and at least one wiring device aperture therethrough from said front face to said rear face having a third predetermined periphery greater than said first predetermined periphery and less than said second predetermined periphery into which at least said front face of said wiring device may extend;

f) one or more second spaces between said first periphery of said front face of said wiring device and the third periphery of its associated one of said at least one wiring device aperture which may permit moisture and debris to enter said enclosure and impede or prevent the proper operation of said wiring device;

g) flexible, resilient seal means extending over the entirety of said front face of said wiring device to prevent moisture and debris from passing through said one or more first spaces, said seal means further extending beyond said third periphery of said at least one wiring device aperture to prevent moisture and debris from passing through said one or more second spaces into and about said wiring device enclosure to impede or prevent proper operation of said wiring device; and

h) at least one fastening means extending through said at least one second aperture in said cover plate and an associated one of said at least one first aperture in said at least one mounting tab into said support whereby said seal means is held in place on said wiring device by the compression of said seal means between said front face of said wiring device and said rear face of said cover plate.

2. A splash for wiring devices as defined in claim 1, wherein said seal means further comprises:

a) a front surface and a rear surface substantially parallel with said front surface;

b) a projection extending outwardly from said seal means front surface; and

c) said projection being dimensioned and configured to provide access to said one or more movable operating means to facilitate manipulation of said one or more movable operating means through said seal means.

3. A splash guard for wiring devices as defined in claim 2, wherein said projection has a front surface for contact by a user to move said one or more movable operating means;

and

a) said rear surface of said seal means having at least one protrusion thereon, said at least one protrusion aligned with at least one of said one or more movable operating means having free end which is spaced a short distance from said at least one or said one or more movable operating means;

b) said at least one protrusion free end brought into contact with its associated at least one of said one or more movable operating means to assist in moving said at least one of said one or more movable operating means in response to depression of said front surface of said seal means by a user.

4. A splash guard for wiring devices as defined in claim 2, wherein said projection is in the form of a truncated pyramid having a rectangular base and a truncated top surface and said truncated top surface is parallel to said front face of said seal means.

5. A splash guard for wiring devices to prevent moisture or debris from entering into or about a wiring device comprising:

a) a wiring device having a front face, a rear face, two side faces, a top face and a bottom face so assembled as to provide a six-sided enclosure for the operative components of said wiring device;

b) at least one mounting tab, having at least one first aperture through each of said at least one mounting tab, on said wiring device for attaching said device to a support;

c) one or more movable operating means extending through said front face for engagement and operation of said one or more movable operating means by a user;

d) one or more first spaces between each of said one or more movable operating means and said front face of said wiring device, which may permit moisture and debris to enter said enclosure and impede or prevent the proper operation of said wiring device;

e) a cover plate having a front face and a rear face and at least one second aperture and at least one wiring device aperture through which at least said front face of said wiring device may extend;

f) one or more second spaces between a periphery of said front face of said wiring device and its associated one of said at least one wiring device aperture which may permit moisture and debris to enter said enclosure and impede or prevent the proper operation of said wiring device;

g) flexible, resilient seal means extending over the entirety of said front face of said wiring device to prevent moisture and debris from passing through said one or more first spaces, said seal means further extending about the periphery of said front face of said wiring device to prevent moisture and debris from passing through said one or more second spaces into and about said wiring device enclosure to impede or prevent proper operation of said wiring device;

h) at least one fastening means extending through said at least one second aperture in said cover plate and an associated one of said at least one first aperture in said at least one mounting tab into said support whereby said seal means is held in place on said wiring device by the compression of said seal means between said front face of said wiring device and said rear face of said cover plate;

said seal means further comprising;

i) a front surface and a rear surface substantially parallel with said front surface;

j) a projection extending outwardly from said seal means front surface;

k) said projection being dimensioned and configured to provide access to said one or more movable operating means to facilitate manipulation of said one or more movable operating means through said seal means;

l) said seal means has a first wall extending from said seal means rear surface and terminating in a free end, said first wall forming an enclosed region with an open rear face; and

m) said enclosed region being dimensioned and adapted to receive therein said front face and a portion of each of the two side faces, said top face and said bottom face.

6. A splash guard for wiring devices as defined in claim 5, further comprising:

a) an outward extension, terminating in a free end, and connected to the free end of said first wall and extending in a plane parallel to said seal means front face.

7. A splash guard for wiring devices as defined in claim 6, further comprising:

a) a second wall extending completely about the free end of said outward extension and in parallel, spaced apart relation to said first wall;

said second wall having a free end and being shorter than said first wall;

said second wall being compressed between the back face of said cover plate and the front face of said wiring device as said at least one fastening means is advanced into said support whereby said one or more second spaces are sealed.
