Adjustable height aid for stretching a sheet

摘要

An adjustable height device for aiding in the stretching of a sheet. The device may include a bracket for attaching the device to a bottom surface of a bed frame, a first connector attached to the bracket by a first rotating element so that the first connector can rotate about the first rotating element with respect to the bracket, a telescoping shaft attached to the first connector by a second rotating element so that the telescoping shaft is rotatable about the second rotating element with respect to the first connector, and a gripping device attached to the telescoping shaft by a second connector. The telescoping shaft may be made of an inner shaft slidably inserted into an outer shaft. The gripping device may include a base having a first gripping surface and a movable element having a second gripping surface rotatable about a rotational axis with respect to the base.

主权项

1. An adjustable-height device to aid the stretching of a sheet on a bed having a bed frame, the device comprising:
a bracket for attaching the adjustable-height device to a bottom surface of the bed frame; a first connector attached to the bracket by a first rotating element, wherein the first connector is rotatable about the first rotating element with respect to the bracket; a telescoping shaft attached to the first connector by a second rotating element, wherein the telescoping shaft is rotatable about the second rotating element with respect to the first connector, wherein the telescoping shaft includes an inner shaft slidably inserted into an outer shaft; and a gripping device attached to the telescoping shaft by a second connector including a shoe sized to allow for insertion of a foot attached to the gripping device, where the foot and the shoe may be detached after insertion, wherein the gripping device includes:
a base having a first gripping surface, anda movable element having a second gripping surface rotatable about a rotational axis with respect to the base between:
a free position in which the first gripping surface is spaced apart from the second gripping surface, anda gripping position in which the first gripping surface is in direct or indirect contact with the second gripping surface, wherein the movable element is a rotationally symmetrical cylinder having a center axis offset from the rotational axis.
