All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in applications, published applications and other publications that are herein incorporated by reference, the definition set forth in this document prevails over the definition that is incorporated herein by reference.
Referring now to the figures FIG. 1 is a top cross-sectional view of a device for handling a door, in which a panel extends laterally from a base unit, according to some embodiments of the present invention.
The device 100 is configured to be joined to a door 200 for handling (opening and closing) the door 200 in a hands-free manner, as will be explained below. The door 200 extends between a hinge end 202 of the door and handle end 204 of the door. The hinge end 202 is joined to a door frame via one or more hinges 206, such that rotation of the door 200 around the hinge(s) 206 is used to selectively open the door 200 and close the door 200. The handle end 204 is opposite the hinge end 202. A door handle 208 is located on the door near the handle end 204, to enable a user to hold the door and apply a force to the door and cause the door to rotate about the hinge(s) 206.
The door handle 208 includes a stem 210 and a hand grip 212. The stem is joined to the door 200 and extends forward from a front surface 200a of the door 200. The hand grip 212 is joined to the stem and is shaped to enable the user to grip the hand grip 212 and pull or push the door 200 to cause the door 200 to rotate around the hinge(s) 206.
The device 100 includes a base unit 102 and an extension unit or panel 104. The base unit has channel 106 opening at a bottom section of the base unit 102 and closed by a top section of the base unit 102 (as will be seen in later figures). The channel is shaped to receive at least one portion of the stem 210 of the door handle 212 so as to slip the base unit 102 onto the door handle 208 and connect the base unit 102 to the door handle 208. In the drawings, the channel 106 is shown to be substantially larger that the door handle, for clarity purposes alone. In some embodiments of the present invention, the channel 106 is shaped to provide a supple and stable fit over the door handle 208. Thereby, the base unit 102 and the door handle 208 make a sturdy snug fit connection, without requiring further reinforcements. The orientation of the base unit 102 relative to the door handle 208 remains fixed. The base unit 102 can be designed or configured to fit tightly against the front surface 200a of the door 200 so that leverage forces against the front surface 200a of door 200 helps stabilize the base unit 102. This prevents the base unit 102 from becoming loose or “wobbly” over time.
The extension unit 104 extends outwardly from the base unit 102 and includes a panel substantially parallel to the door. A force applied on the panel of the extension unit 104 is transferred to the base unit 102, via the base unit to the door handle 208, and via the door handle 208 to the door 200. In the embodiment of the FIG. 1, the extension unit 104 extends beyond the width of the door 200. In some embodiments of the present invention, the base unit 102 has a rear surface 102a facing the door 200 when the base unit 102 is connected to the door handle 208, a front surface facing 102b away from the door 208 when the base unit 102 is connected to the door handle 208, and lateral surfaces 102c extending on lateral sides of the base unit 102 between the rear surface 102a and the front surface 102b. In some embodiments of the present invention the extension unit (panel) 104 extends sideways from the base unit either directly from the base unit 102 or via a connection unit 108 which connects one of the lateral surfaces 102c of the base unit 102 to the panel 104 (as shown in the example of FIG. 1). In the example of FIG. 1, the panel 104 extends away from the hinge end 202 of the door and extends beyond the width of the door.
When the device 100 is joined to the door handle 208, a gap 110 is formed between a wall 220 (which lies beyond the handle end 204 of the door) and the panel 104. In this manner, a shoulder or elbow of a user can be physically inserted in the gap 110 to contact the panel 104 and apply a force against the panel 104. The force received by the panel 104 is transferred to the base unit 102, the door handle 208, and door 200, and therefore enables a user to open the door in a hands-free manner.
In the example of FIG. 1, the base unit 102 connects to the panel 104 via a connection unit 108. The connection unit 108 may taper from front to rear and may be wider near the panel 104 than near the door 200. In this manner the connection line between the connection unit 108 and the panel 104 is at an angle that is larger than 90 degrees. This forms a V-shaped reinforcement location between the connection unit 108 and the panel 104, and adds structural strength to the device 100. In this manner, bending at the connection location is decreased and a force applied to the panel 104 is more efficiently transferred to the base unit 102 and the door 104. Moreover, the added structural integrity increases the resistance of the panel 104 to breakage from the connection unit when a force is applied to the panel 104.
While the base unit 102, panel 104, and connection unit 108 are described as different units, these units may be integral with each other and formed as a single piece of material, such as molded plastic. In another variant, one or more may be discrete units joined to each other. The finish of the base unit 102 may smooth as to not scrape the front surface 200a of the door 200 or the door handle 208.
FIG. 32 is a perspective view of the device 100 of FIG. 1 before connection to the door handle 208, according to some embodiments of the present invention. FIG. 33 is a perspective view of the device 100 of FIG. 1 after connection to the door handle 208, according to some embodiments of the present invention.
FIG. 2 is a top cross-sectional view of a device for handling a door, in which a panel extends laterally from a base unit and a connection unit with a rounded surface, according to some embodiments of the present invention.
The device 100 of FIG. 2 has all the features of device 100 of FIG. 1, described above. The difference lies in the fact that in FIG. 2, the connection unit 108 has a curved surface, such that the reinforcement location at which the connection unit 108 and the panel 104 meet is about 180 degrees.

The connection unit 108 extends forward from the front surface 102b of the base unit 102, and having a front section joined to the panel 104, such that a gap 110 is formed between the panel 104 and the front surface 102b of the base unit 102. In this manner, a user may place a shoulder or elbow in the gap 110 to manipulate the door.
In some embodiments of the present invention, the panel 104 has a rear surface 104a facing the base unit 102 and front surface 104b facing away from the base unit, and the rear surface 104a is joined to the connection unit 110 at an angle larger than 90 degrees and smaller than or equal to 180 degrees. As explained above, this increases the structural strength of the panel and enables more efficient transmission of force from the panel 104 to the door 200.
In the device 100, the base unit 102 has a first lateral side 102c and a second later side 120d opposite each other and connecting the front surface 102b to the rear surface 102a. The connection unit 108 extends forward from a portion of the front surface 102b at or near the second lateral side 102d. The first lateral side 102c is closer to the hinge end 202 than the second lateral side 102d is, such that the panel 104 extends from the connection unit 108 toward a projection 300 of the first lateral side 102c and toward the hinge end 202. The panel may extend beyond the projection of the first lateral side. In other words, the panel 104 extends laterally ahead of the front surface 102b from the connection unit 108 in a direction C that extends from the second lateral side 102d to the first lateral side 102c. In other words, when joined to a door handle, the panel 104 extends from the connection unit 108 toward from the hinge end 202 of the door 200.

The device 100 of FIG. 24 has all the features of device 100 of FIG. 23, described above. The difference lies in the fact that in FIG. 24, the connection unit 108 has a curved surface, such that the reinforcement location at which the connection unit 108 and the panel 104 meet is about 180 degrees.
FIG. 25 is a top cross-sectional view of a device for handling a door, in which, in which a base unit surrounds the door handle and a panel is located ahead of the base unit and extends away from a hinge end of the door, according to some embodiments of the present invention. FIG. 26 is a front view of the device of FIG. 25, according to some embodiments of the present invention. FIG. 27 is a rear view of the device of FIG. 25, according to some embodiments of the present invention. FIG. 28 is a bottom view of the device of FIG. 25, according to some embodiments of the present invention.
The device 100 of FIGS. 25-28 is similar to the device 100 of FIG. 23 and of FIG. 24. In addition to all the features described with reference to FIGS. 23 and 24, the base unit 102 of the device 100 of FIGS. 25-28 also surrounds the hand grip 212. Therefore, the channel 106 is shaped to receive at least one portion of the stem 210 of the door handle and also to receive the hand grip 212 of the door handle. As mentioned above, in some embodiments of the present invention, the channel 106 is configured for a snug connection with the door handle (stem 210 and hand grip 212) to prevent wobbling and to efficiently transfer force from the panel 104 to the door 200.
In the examples of FIGS. 25 to 28, the connection between the connection unit 108 and the panel 104 is angular, as described with reference to FIG. 23. However, in some embodiments of the present invention, the connection between the connection unit 108 and the panel 104 is curved, as described above, with reference to FIG. 24.
FIGS. 26 and 27 show that the top section 107 of the base unit 102 is closed, to stop the device 100 from slipping down the door handle and falling on the floor. Due to this stopping function of the top section 107 of the base unit, the door handle supports the weight of the device 100 when the device 100 is joined to the door handle.
FIG. 29 is a perspective view of the device of FIG. 25 before connection to the door handle, according to some embodiments of the present invention. FIG. 30 is a perspective view of the device of FIG. 25 after connection to the door handle, according to some embodiments of the present invention; and
FIGS. 29 and 30 are three-quarters views showing the rear surface 102a of the base unit. The channel 106 and the door handle 208 may L-shaped bottom cross-sections. In a variant the door handle has a bulb-shaped hand grip, and the channel 106 is shaped to receive at least part of the stem and the bulb-shaped hand grip, as described above with reference to FIGS. 13 and 14.
In a variant, the entirety of the door handle 208 is enclosed in the channel and the rear surface of the door handle 208 is flush with the rear surface 102a of the base unit. In another variant, the door handle 208 may jut out of the rear surface 102a of the base unit and/or out of the bottom of the base unit, as explained above with reference to FIGS. 9-12.
FIG. 31 is a top cross-sectional view of a device for handling a door 100, in which a connection unit 108 extends forward from a front surface 102a of a base unit 102 which is near the lateral surface 102c facing the hinge end 202 of the door 200, and a panel 104 extends from the connection unit 108 toward a hinge end 202 of the door 200 to form a gap 110 between the door 200 and the panel 204, according to some embodiments of the present invention.
The device 100 of FIG. 31 is similar to the device 100 of FIG. 25. The connection unit 108 extend forward from the front surface 102b of the base unit 102 near the first lateral surface 102c facing the hinge end 202 of the door 200. The difference lies in the fact that in FIG. 31, the panel 104 extends from the connection 108 toward the hinge end 202 of the door. Therefore, when the device 100 is joined to the door handle 208, the gap 110 is created between the panel 104 and the door 200.
The connection between the connection unit 108 and the panel 104 may be curved or angular, as explained above.
