Description

TECHNICAL FIELD

Exemplary embodiments relate generally to a removable or adjustable cover for a garage door sensor.

BACKGROUND AND SUMMARY OF THE INVENTION

Garage door sensors are common fixtures in the modern home and are sometimes required by law. Such sensor systems generally comprise a pair of photo eyes located on opposite sides of an opening to a garage. One or both sensors transmit a signal which is received by the opposing sensor. Interruption of this signal, such as by breaking the line of sight between the sensors, may cause garage door operation to be interrupted or prevented. Generally, interruption of the beam while the garage is being closed causes the garage door to reverse directions and begin opening. Generally speaking, the objective behind such sensor systems is to prevent the garage door from closing on a person or object.

These sensors, particularly where they comprise photo eyes, may be affected by ambient lighting. For example, during sunrise and sunset hours, ambient light may strike one or both of the sensors, causing them to malfunction. It is known to place covers over one or both sensors to limit the ability for ambient light to strike one or both sensors. However, such covers generally require customization and are difficult to make and install. Furthermore, such covers are generally non-adjustable. Further still, these covers sometimes become broken or otherwise in need of repair and replacement. As another example, these covers sometimes gather debris such as leaves, dust, twigs, cobwebs, insects, and the like, which may result in malfunction of the sensors. Therefore, what is needed is a removable or adjustable cover for a garage door sensor.

A removable or adjustable cover for a garage door sensor is provided. The cover may comprise a square or rectangular shape cover which is configured for sliding movement with respect to the sensor. The cover may comprise a slot which permits removal and/or adjustment with respect to the distance the cover extends from a distal end of the sensor. A receiving portion may be provided on a top surface of the sensor and may be configured to receive a fastener. The receiving portion may comprise an aperture, notch, protrusion, indentation, shelf, some combination thereof, or the like. A proximal end of the fastener may be received within the receiving portion, pass through an aperture in a mounting frame, and through the slot. A nut may be secured to a distal end of the fastener protruding from the aperture to secure the cover to the frame. In this way, the sensor may be secured to the frame by a press-fit, mechanical compression, friction, some combination thereof, or the like.

Various types of garage door sensors may be constructed differently and therefore necessitate different cover embodiments. In exemplary embodiments, the removeable cover may comprise a hollow, cylindrical shape. The cover may be configured to fit within a recess between a protrusion formed in a housing of said garage door sensor for a photo eye of the garage door sensor and the photo eye. The cover may comprise a sidewall thickness configured to provide a friction fit between the protrusion and the photo eye to removably secure said cover within a gap defined, at least in part, by an inner surface of said protrusion and an outer surface of said photo eye. The protrusion may comprise a hollow cylindrical shape. The photo eye may comprise a generally cylindrical shape. The garage door sensor may be mounted to a frame configured for selective attachment to a wall, track for a garage door, combinations thereof, or the like.

In other exemplary embodiments, the cover may comprise a hollow cylindrical shape with a rear surface located at a distal end thereof. The rear surface may comprise an aperture configured for placement between a rear surface of said photo eye and/or a rear surface of the protrusion and a front surface of said frame and/or a front surface of the housing for the garage door sensor. In this manner, the cover may be secured frictionally within a gap between the rear surface of the protrusion and/or or a rear surface of the photo eye and a front surface of said frame and/or a front surface of the housing for the garage door sensor.

In still other exemplary embodiments, the cover may comprise a multi-part case. The case may comprise a first portion and a second portion, for example. The first and second portions may be configured for joining about some or all of the garage door sensor. The case may generally conform to the shape of the underlying sensor when joined. The first and second portions may be joined in a removeable or semi-permanent fashion. A portion of the case may protrude outward to extend beyond a housing of the sensor when installed, such as to shield the sensor from ambient light. The protruding portion may be length adjustable. The cover may be configured to accommodate electrical connections for the garage door sensor and/or the mounting frame for the garage door sensor.

Further features and advantages of the systems and methods disclosed herein, as well as the structure and operation of various aspects of the present disclosure, are described in detail below with reference to the accompanying figures.

The frame 10 may form a substantially “L” shape, though any shape is contemplated.

The frame 10 may comprise a clip 19 for attachment to the track 3 or other component of the garage door assembly 9, though such is not required. Any size, shape, or kind of frame 10 is contemplated. The frame 10 may be configured to secure the sensor 50 in position, preferably aligned with a second sensor 50, a reflector plate 7, or the like. In exemplary embodiments, at least one sensor 50 may be installed on either side of an opening 5 for a garage door 15. In other exemplary embodiments, a single sensor 50 may be positioned on one side of an opening 5 for a garage door 15 and a reflector plate 7 may be located on the opposing side of the opening 5.

Some or all of the cover 30 may be shaped as a hollow cube, cuboid, and/or cylindrical shape, though any size or shape is contemplated. The cover 30 may be comprised of a rigid polymer, though any material is contemplated. In exemplary embodiments, the cover 30 may be the same shape as the sensor 50. The hollow portion of the cover 30 may be configured to fit over some or all of the sensor 50. Sufficient clearance may be provided between the cover 30 and the sensor 50 to permit axial adjustment of the cover 30 relative to the sensor 50.

The cover 30 may be configured for movement relative to the sensor 50. Alternatively, or additionally, the cover 30 may be configured for movement relative to the frame 10. In this way, the distance the cover 30 extends from the sensor 50 may be adjusted. This may permit control of the amount of ambient light allowed to contact the sensor 50, as well as clearance for passing vehicles, some combination thereof, and the like. The cover 30 may comprise a slot 32. The slot 32 may extend along some or all of the cover 30 to facilitate movement of the cover 30. The slot 32 may comprise one or more protrusions or the like configured to selectively and temporarily secure the cover 30 at any one or a number of positions.

The cover 30 may be configured for selective removal such as for replacement, repair, some combination thereof, or the like. In exemplary embodiments, the slot 32 may extend along an upper surface of the cover 30 to an outer edge of the cover 30 so as to facilitate removal of the cover 30 from the sensor 50 and/or the frame 10.
