Door hinges are disclosed that are configured to allow operators to hold a door in an open position at specific and desired angles (and for such specific and desired angles to be easily and quickly modulated by an operator). In addition, the door hinges are configured to allow an operator to easily and quickly establish a maximum angle by which the hingeand its attached doorare allowed to be opened, i.e., how wide the hinge and door are allowed to open (which also may be easily and quickly modulated by an operator).

An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. One end of the torsion spring is fixed to a spring tension trolley. The trolley translates within a trolley guide mounted to the building structure. The other end of the torsion spring is fixed to a shaft running through the torsion spring. This allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the snake-like or serpentine appearance from an improper fixed torsion spring length.

A door stop device is disclosed. A door stop device comprising a rope with a top portion and a bottom portion, a top rope holder, a bottom rope holder, a first ring, a lockable ring, a wire ring, a foot shaped portion, wherein the top portion of the rope is secured and configured to the top rope holder in such a manner as to form a loop for hanging or attaching the loop around a door handle, wherein the bottom rope holder couples the rope to the first ring, wherein the first ring is linked to the lockable ring, and wherein the lockable ring is linked to the wire ring; and wherein the wire ring is further linked to the foot shaped portion.

A multiplier device is presented for use with a handheld drive device for rotating an output shaft and mating driven member. The multiplier device has a rotational shaft with a first end for mating with the driven member and a second end defining a first slide tip. A first gear is mounted to the rotational shaft, a fixed ring gear presents a toothed inner ring, planetary gears are positioned to contact the inner ring and the first gear. The device releasably mates with the handheld drive device and has a second slide tip for cooperation with the first slide tip.

A door stop device is disclosed. A door stop device comprising a rope with a top portion and a bottom portion, a top rope holder, a bottom rope holder, a first ring, a lockable ring, a wire ring, a foot shaped portion, wherein the top portion of the rope is secured and configured to the top rope holder in such a manner as to form a loop for hanging or attaching the loop around a door handle, wherein the bottom rope holder couples the rope to the first ring, wherein the first ring is linked to the lockable ring, and wherein the lockable ring is linked to the wire ring; and wherein the wire ring is further linked to the foot shaped portion.

A handheld device for rotating a drive shaft including a housing comprising a handle extending from a gear housing; a first shaft that extends rotatably through the housing; a first drive gear secured to the first shaft; a trigger pivotably connected to the first shaft to position the trigger adjacent to the handle, wherein the movement of the trigger rotates the first shaft and first drive gear; a second shaft gear in contact with the first drive gear and supported on a second shaft that extends rotatably through the housing; a second drive gear positioned on the second shaft; a third shaft gear in contact with the second drive gear and supported on a slidable third shaft that extends rotatably through the housing and is slidable in the housing and the third shaft gear remains in contact with the second drive gear when slid and a third forward gear attached to the slidable third shaft on one side of the third shaft gear; a third reverse gear attached to the slidable third shaft on the other side of the third shaft gear.

A non-invasive doorstopper includes first and second arms extending outwardly between a bridging element/base, the bridging element being configured to engage with an edge of a door and the arms being arranged to engage operably with opposite sides of the door. The first arm is resilient and movable against a base to clip onto the side of the door, i.e. to a top or bottom edge. The doorstopper includes a protruding element extending from one of the arms and it extends towards a wall adjacent to a frame to which the door is hingedly connected, the protruding element being configured to engage with the wall ahead of the door for preventing the door from impacting or engaging directly with the wall.

A device to apply a rotational force to a spring of a rollup or overhead garage door counterbalancing mechanism. The device has a rotatable driven member mounted in a housing. The housing and the driven member have slots with an open end adapted to receive the shaft of the overhead garage door counterbalancing mechanism. A coupling member is configured to mount to the driven member and connect the driven member to the winding cone of a garage door spring to apply rotational force to the spring. The housing with the driven member may be connected to the body of an existing power tool in place of the original tool head, or, the housing may be permanently combined with a motor and transmission to provide a special purpose tool.

In an installation adjustment device for an auto-return arrangement which comprises a support rod with a front stop surface and an adjustable slide which is slideably supported on the support rod so as to be stepwise position-adjustable, the slide is provided with an adjustment surface which extends parallel to the stop surface and the normal vectors pointing to the stop surface and the adjustment surface have the same direction, whereby the adjustment of an auto-return arrangement is facilitated.
