A portable door guard for sliding over a hinge of a door, the portable door guard comprising a body comprising a hollow cylindrical section including an opening gap along the length of the hollow cylindrical section on a stationary section of a back face of the body, the hollow cylindrical section comprising a C shaped profile capable of fitting over a hinge, wherein the hinge comprises a barrel, a first wing, and a second wing, the first wing being mounted on a door frame, and the second wing being mounted onto the door, and the barrel holding the first wing and the second wing together while acting as a pivot. The portable door guard further comprising a body section configured to impede the door from opening more than a given amount, the body section capable of being extended and shortened.

The present invention is a preventive maintenance system and kit that can prolong the life of the regulators and motors. In performing repairs to automobile power window regulators and motors, it is often the case that the repair is required due to a breakdown of the lubricant. This breakdown can be due to several factors, such as age, temperature, dirt, and salts. The window regulators and motors, without appropriate lubrication, will fail and lead to more costly repairs. A kit has been developed to service the electric windows of an automobile without disassembling the door is presented. The kit provides for access to the door interior and for lubricating the interior parts. The kit and method is designed to lubricate the many window parts in order to extend their life and maintain functionality.

A portable door guard used to secure the door at the hinge, particularly the wings of the hinge. The portable door guard comprises a retractable, non-permanently fixed device that can be secured around the hinge of the door from the inside to prohibit the door to open more than a gap. The portable door guard includes a center area designed to grip the hinge to limit the swinging movement of the hinge and adjusting means to configure the size of the gap.

A window stop device is adapted for limiting sliding movement of a window sash along a rail, and includes a restraining unit and a lever unit pivoting on the restraining unit between a locked position and an unlocked position. The restraining unit includes a pair of clamping members for flanking the rail. In the locked position, pressing arms of the lever unit press the clamping members, respectively, so that the clamping members clamp tightly the rail therebetween. In the unlocked position, the pressing arms are away from the clamping members so as to release the clamping members and permit sliding movement of the restraining unit along the rail.

A doorstop system includes a doorstop and a bracket. The doorstop includes a foot, a recess area within the foot, an opening in a bottom surface of the foot around the recess area, and pockets in opposite sides of the recess area extending to the bottom surface of the foot. The bracket is sized to fit into the recess area of the doorstop and includes a body and protrusions on opposite sides of the body. The protrusions are positioned and sized to mate with the doorstop pockets.

In the case of a hinge having a body hinge part which can be preassembled on a body and a door hinge part which can be preassembled on a door leaf, wherein the hinge parts are connected to each other in an articulated manner, provision is made for the body and door hinge parts to have respective flange parts fastenable onto a surface, and a height- and depth-adjusting device is arranged in the body flange part and has at least one first fastening element which can be used to fix the set height and depth position of the door leaf in relation to the body.

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.

A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.

An apparatus comprising a baseplate configured to be coupled to an interior side of an inswing door adjacent a pivot edge of the door; a rotatable closing arm with a first end and a second end, the second end coupled to a motor, the motor configured to be engaged in response to receipt of a signal from a remote electronic device; and circuitry electrically coupled between a power supply and the motor, the circuitry configured to wirelessly send and receive information to and from the remote electronic device.

A revolving door (100) is provided. The revolving door (100) comprises a base portion (110), an upper portion (120), and a rotating assembly (130) extending between the base portion (110) and the upper portion (120), and at least one door panel (140) connected to the rotating assembly (130) and being rotatably arranged around a central axis (A1). The revolving door (100) further comprises one or more lifting means (111a-b, 121).
