This disclosure is in the field of openers for doors. More specifically, this disclosure is in the field of foot-operated door openers.
In various embodiments, the foot-operated door opener comprises a support member mounted on a door by a mounting member. The support member movably supports a foot puck that allows a user to pull a door open using their foot. In some embodiments the support member may be folded to a stowed configuration when not in use.
In certain circumstances it is desirable to be able to open a door using a foot-operated door opener. This allows a user to open a door without potential germ-transferring contact between their hands and a common door handle. It also allows a user to open a door while holding other items in their hands. Referring now to
In the depicted embodiments, the door opener 100 comprises a support member 102 that provides support to a foot member, or “puck”, 104 movably disposed on the support member 102. The support member 102 is attached to a mounting member 106 for attaching the door opener 100 to a door. A user may pull a door open by placing one foot on the foot member 104, tilting the foot member 104 in relation to support member 102, and pulling back on foot member 104 away from the door.
In the embodiment depicted in
The support member 102 provides support to foot member 104 but allows it to tilt, pivot, rotate, or otherwise move with respect to support member 102 as particularly shown in
The support member 102 may be made up of one or more component parts and may be fixed to or removable from the mounting member 106. The attachment between the support member 102 and the mounting member 106 may be welded attachments, screw or bolt attachment, adhesive attachment, or integrally formed using printing, casting, or machining as a single piece of material. The component parts of the door opener 100 may be formed from any material with suitable strength and other characteristics sufficient to provide the functions described herein, including various metals, plastics, composites, or other materials. In the depicted embodiments, the support member 102 has a substantially circular opening with edge 102d for receiving the foot member 104. In this embodiment an inclined bearing surface 102a extends around the edge 102d of support member 102 adjacent to the circular opening or aperture. In this embodiment, the inclined bearing surface 102a extends around the entire edge 102d of the opening to allow the foot member 104 to rotate through 360 degrees and to tilt in any direction. In some embodiments, the inclined bearing surface 102a may only extend along a portion of the edge 102d of the opening. In such embodiments the foot member 104 may only rotate for less than 360 degrees or tilt in a narrower range of directions. In other embodiments the opening may be non-circular in shape or have both arcuate and non-arcuate sections. In other embodiments there may be no aperture in the support member 102, and the foot member 104 may rest on top of the support member 102.
The foot member 104 is movably disposed on the support member 102. In the depicted embodiment a top member 104a forms the top portion of the foot member 104. The upper surface of the top member 104a may be provided with features 104b to increase the friction between the foot member 104 and a user's shoe or foot during use. The features 104b may be formed as part of top member 104a or attached to it. In varying embodiments of the device, all or a portion of the bottom surface of top member 104a comprises one or more bearing surfaces 104f. The bearing surface 102a of support member 102 receives the bearing surface 104f of the top member 102a. In the depicted embodiment the bearing surfaces 102a and 104f are slidably engaged. In other embodiments they may be provide with ball bearings or other means of reducing friction while allowing movement between the support member 102 and the foot member 104. In this embodiment the bearing surfaces 102a and 104f are substantially spherical segments. In other embodiments they may be ovoid, ellipsoid, oblate spheroids, spherical, frusto-conical, or other surface configurations that will allow a desired ability to tilt or rotate.
Referring to the embodiment depicted in
The foot member 104 may also be provided with a bottom member 104c. In some embodiments the bottom member 104c may be attached to the bottom surface of top member 104a or formed unitarily with top member 104a. In the embodiment depicted in
In some embodiments the bottom surface of bottom member 104c may provide additional support to the foot-operated door opener by contacting the floor. The bottom surface of bottom member 104c may slide along the floor as the user operates the door opener. This prevents excessive downward torque on the mounting member 106 and door 108. The bottom surface 104c may be flat or curved. In a preferred embodiment the bottom surface 104c is a section of sphere such as a spherical sector, spherical cap, or a dome.
In some embodiments when the foot member 104 moves away from a center position the component 102a is within socket 104e on one side of the foot member 104, while on the other side of the foot member 104 the flange 102a is not within the socket 104e at all. This engagement of the flanges and sockets helps prevent the foot member 104 from moving past a desired range of motion or from becoming disengaged from the support member 102.
As can be seen with reference to
In this embodiment the hinge pin is disposed above or near the top edge of the support member 106 in the operational configuration shown in
In some embodiments the mounting member 102 and the support member 106 are approximately 6 inches wide. In some embodiments, the mounting member 102 may extend 6 to 7 inches from the mounting member 106. In some embodiments the mounting member is approximately 2 to 4 inches tall. All of the dimensions may vary from embodiment to embodiment so long as they accommodate the intended use of the device to allow a user to engage the foot puck and exert pressure on it to pull the door open.
“Substantially” means to be more-or-less conforming to the particular dimension, range, shape, concept, or other aspect modified by the term, such that a feature or component need not conform exactly. For example, a “substantially cylindrical” object means that the object resembles a cylinder but may have one or more deviations from a true cylinder.
“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional, unrecited elements or method steps.
Changes may be made in the above methods, devices and structures without departing from the scope hereof. Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention have been described with the intent to be illustrative and exemplary of the invention, rather than restrictive or limiting of the scope thereof. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. Specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one of skill in the art to employ the present invention in any appropriately detailed structure. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims.
