Conventional leg rests are not readily portable and adjustable for different settings (e.g., installations).
A leg/footrest apparatus includes an adjustable-length axle having a compression rod to force first and second ends of the axle away from one another, and a rest platform that is rotatable about a longitudinal axis of the axle. The apparatus may include a U-shaped member having first and second ends that extend from the axle and a base portion that extends between the first and second ends coupled to the rest platform. The rest platform may be rotatable about the base portion and may be balanced such that a rest surface of the rest platform remains substantially horizontal as the U-shaped member rotates about the axle. The rest platform may be rotatable between an in-use orientation and a storage orientation. A rotational lock may releasably secure the rest platform in the storage orientation. A foot pedal may be configured to rotate the rest platform between the in-use and storage orientations.
In the drawings, the leftmost digit(s) of a reference number identifies the drawing in which the reference number first appears.
Disclosed herein are portable and configurable rest apparatuses on which to rest legs and/or feet.
Axle 104 may be configured as or may include a compression rod configured to force first and second ends 106 and 108 away from one another, in directions of arrows 110 and 112. Axle 104 may include, for example, a spring that is compressible by rotating ends 106 and 108 relative to one another. In this example, a length of axle 104 may also be adjusted by rotating ends 106 and 108 relative to one another. Alternatively, or additionally, axle 104 may include a sealed or sealable gas chamber.
In the examples above, a length of axle 104 may be adjusted to a length that is slightly greater than a width 208 between opposing walls 204 and 206. Ends 106 and 108 may then be pressed slightly towards one another (i.e., in directions opposite of directions 110 and 112), positioned between walls 204 and 206, and released. Upon release, the compression rod of axle 104 will slightly expand the length of axle 104 to press ends 106 and 108 against walls 204 and 206, and thereby maintain a position of axle 104.
Rest apparatus 100 may further include first and second end pads 114 and 116, each coupled to respective ends 106 and 108 of axle 104. End pads 114 and 116 may be configured to protect surfaces of walls 204 and 206 from scratches and/or other damage from axle 104.
Rest platform 102 may be fully rotational about the longitudinal axis of axle 104 (i.e., 360 degrees). Alternatively, rest platform 104 may be rotatable between a first orientation and a second orientation. The first orientation may correspond to an in-use position. The second orientation may correspond to an out-of-the way or storage position.
In the second orientation, rest surface 118 may be substantially vertical as illustrated in
In the examples of
In an embodiment, rest platform 102 and axle 104 are integral with one another. In this example, first end 106 of axle 104 extends from a first side of rest platform 102, and second end 108 of axle 104 extends from a second side of rest platform 102, opposite the first side.
Rest platform 102 may be configured to rotate about axle 104, and axle 104 may be stationary relative to end pads 114 and 116. Alternatively, or additionally, axle 104 may be configured to rotate relative to end pads 114 and 116.
In an embodiment, a rest apparatus includes a U-shaped extension, which may be useful to provide a greater range of motion to a rest platform. Examples are described below with reference to
Axle 604 may be configured as described above with respect to axle 104.
U-shaped member 640 is rotatable about a longitudinal axis of axle 604. In an embodiment, axle 604 does not rotate relative to desk 630, and U-shaped member 640 rotates about axle 604. In another embodiment, U-shaped member 640 and axle 604 are fixedly coupled to one another, and U-shaped member 640 and axle 604 rotate about the axis of axle 604.
U-shaped member 640 may be rotatable between first and second orientations, examples of which are provided below with reference to
As illustrated
Rest platform 602 may be connected to base portion 646 in a variety of ways. As an example, and without limitation, base portion 646 may include a rod that extends between first and second ends 642 and 644 of U-shaped member 640, and through rest platform 602. Rest platform 602 and/or base portion 646 may include ball bearings to provide for smooth rotation of rest platform 602 about base portion 646. In another embodiment, rest platform 602 may be connected to base portion 646 with relatively loose-fitting U-type connectors. A rest apparatus is not, however, limited to these examples.
In
A U-shaped member, such as described above, may provide a greater range of motion to a rest platform. The greater range of motion may be useful to re-orient rest platform to an out-of-the way orientation.
A rest apparatus as disclosed herein may include a foot pedal to rotate a rest platform. The foot pedal may extend from an axle (e.g., axle 104 in
A rest apparatus as disclosed herein may include a rotational lock to releasably secure a rest platform in one or more orientations. Where the rest apparatus includes a foot pedal to rotate a rest platform, the foot pedal may be further configured to engage and disengage the lock. For example, and without limitation, the foot pedal may be configured to rotate the rest platform from a first orientation to a second orientation and engage the lock in response to a first physical force applied to the foot pedal. The foot pedal may be further configured to release the lock in response to a second physical force applied to the foot pedal subsequent to application of the first physical force. The rest platform is configured to return to the first orientation when the lock is released, by gravity and/or other mechanism.
A rest apparatus as disclosed herein may include a ratchet mechanism operable by a foot pedal to rotate a rest platform in response to a force applied to the foot pedal.
A rest apparatus as disclosed herein may include multiple foot pedals extending from the axle. For example, and without limitation, a first foot pedal may extend from the axle to rotate a rest platform from a first orientation to a second orientation in response to a physical force applied to the first foot pedal. A second foot pedal may extend from the axle, perpendicular to the first foot pedal, to rotate the rest platform from the second orientation to the first orientation in response to a physical force applied to the second foot pedal.
A rest apparatus as disclosed herein may include a cushion attached to a surface of a rest platform.
Apparatuses are disclosed herein with the aid of functional building blocks illustrating functions, features, and relationships thereof. At least some of the boundaries of these functional building blocks have been arbitrarily defined herein for the convenience of the description. Alternate boundaries may be defined so long as the specified functions and relationships thereof are appropriately performed. While various embodiments are disclosed herein, it should be understood that they are presented as examples. The scope of the claims should not be limited by any of the example embodiments disclosed herein.
