A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.

A door stop includes an elongated body defining an axis, at least one attachment structure disposed near a first end of the elongated body, and at least one adornment coupler. The adornment coupler can include a channel formed in the elongated body parallel to its axis and having a cross-section in the shape of an inverted “T”. The adornment coupler enables different adornments to be interchangeably attached to the door stop. An adornment of the invention includes a decorative portion and a mounting structure coupled to the decorative portion. The mounting structure is configured to removably engage a complementary adornment coupler (e.g., the channel) of the door stop, whereby the adornment can be mounted to the door stop.

A hinge for a door of a storage unit and a method of repairing a storage unit that includes a pivotable door. The hinge including a first bracket and a second bracket. The hinge further including a linking mechanism for coupling the second bracket to the first bracket so that the second bracket is able to translate and rotate relative to the first bracket, wherein a maximum amount of rotation of the second bracket relative to the first bracket is not determined solely by operation of the linking mechanism.

A pivot hinge bracket assembly for use with a pivot hinge for a reach-in type cool room refrigerator includes two mirror imaged main bracket portions and a pivot plate removably coupled to one of the main bracket portions. The main bracket portion includes an edge mounting flange extending to a rear mounting flange mounted to the cool room refrigerator door jamb. The edge mounting flange has a modified square mounting hole and pivot pin plate screw mounting holes. The rear mounting flange has two door screw mounting holes. The pivot plate includes a pivot plate mounting flange and a pivot pin. The pivot hinge bracket assembly also includes an optional removably coupled door stop.

A door prop includes a rectangular wedge secured horizontally by a first elastic cord in a horizontal position adjacent the door frame upon a door when the door is open. A second elastic cord enables a user to move the wedge away from propping the door when the door is desired to be closed.

The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

A glass panel system comprising an upper and lower guide track and at least two adjacent glass panels which are movable along the lower and upper guide tracks. The lower guide track is configured to support at least two glass panels. The upper guide track comprises two opposite side walls, an elongated groove and a free space formed between the two side walls. One of the glass panels leans against both the side walls by one guide element and against one of the two side walls and against another glass panel by another guide element. One of the glass panels leans, on one hand, against one of the two side walls and against another glass panel by one guide element and, on the other hand, against the other side wall and against another glass panel by another guide element. The guide elements are arranged in the free space.

The door stopper is adhered to the front wing of the door that has been completely opened and the door is prevented to move from this point on. When the door is desired to be closed, the door is pulled gently by hand, the force applied by the door to the stopper tensions the pressure spring and the pressure spring forces the moveable head down to the floor, thereby enabling the door to pass over the stopper.

A window lift system including a first guide rail including a first stop, a second guide rail which has a second stop in an upper end region, a first slider guided on the first guide rail, second slider guided on the second guide rail, cable drum, and a drive cable driven by means of the cable drum and coupled to the sliders and extending through a Bowden cable sheath between the upper end region of the second guide rail and a lower end region of the first guide rail. The sliders are movable by the drive cable along the guide rails into a stop position in which the second slider lies against the second stop and the first slider is spaced apart from the first stop by a predefined distance, ranging between 0.4 percent and 1.2 percent of the length of the Bowden cable sheath.

A drive mechanism for imparting movements to a door which pivots about a generally vertical axis between open and closed positions. The drive mechanism includes a frame, a power source mounted on the frame or positively driving an output shaft of the drive mechanism and thus, moving the door from a closed position toward an open position. The drive mechanism also includes an output shaft mounted for rotation about a fixed axis disposed generally parallel to a fixed axis of a power source drive shaft. A drive train including a plurality of intermeshing gear sets is arranged between the power source drive shaft and the output shaft. At least one gear set in the drive train includes a clutch mechanism selectively operable in either an engaged condition or a disengaged condition. When in a disengaged condition, the clutch mechanism operably transfers rotational movements of the power source to the output shaft so as to forcibly open the door. When operated in an engaged condition, the clutch mechanism operationally disconnect the power source and at least one gear set from the drive train thereby minimizing the manual effort required to open the door.
