The pedestal portion is flat and raised from the first sloped portion and the second sloped portion. The doorstop also includes an insert that fits inside the bore, a fastener that holds the insert inside the foot, and a handle adjacent to the insert and used to position the foot.

摘要： A combination doorbumper and doorstopper includes a mounting plate, spindle, bumper, toggle bolt, and toggle bolt anchor. The doorbumper is installed on a wall so that a doorknob or door handle will engage the bumper when the door is fully opened. The spindle is positioned between the mounting plate and the bumper, and includes a narrow neck region. The door can be held in an opened position by placing a loop end of a flexible cord over the doorknob or handle on the opposite side of the door from the doorbumper, and stretching the cord so that a hook at the opposite end of the cord can be placed over the neck of the spindle. The doorbumper together with the flexible cord acts as a doorstopper to hold the door open.

摘要： A doorstop has a foot coupled to a lower end of a handle. The handle of the doorstop has a length that allows a user to insert the foot under a lower edge of a door and to remove the foot from under the lower edge without requiring the user to bend over. The handle is removable from the foot for easy storage and travel. The doorstop foot may include a button for attachment to a clip thereby enabling a user to carry the doorstop on a belt. The coupling between the foot and handle is releasably securable and may be mechanical or magnetic. The handle may also telescope between a contracted position and an extended position.
