A device can include a hinge mechanism rotatably coupling a first portion of the device to a second portion of the device. The hinge mechanism is configured to automatically open the device. The device can also include a damper configured to control a rate at which the hinge mechanism automatically opens the device. The hinge mechanism can include a spine hinge, a rolling contact hinge, a film hinge, or a geared link hinge.

A door stop is insertable between a stationery door frame and a movable door for maintaining the door in an open position. The door stop has a body that includes a base portion, a handle portion, an attachment member, and a tether. The base portion is configured for insertion between the door frame and the movable member. The handle portion is coupled to the base portion. The attachment member is configured for being attached to one of a wall, the door frame and door. The tether is provided with a first end that is coupled to the attachment member, and a second end that is coupled to the body. The insertion of the base member between the door frame and door, and the engagement of the base member with the door frame and door maintains the door in an open position.

An aircraft emergency exit door (10) with opening mechanisms integrated by a grouping of the mechanisms into a door beam (3) located on a given side of a window (16) of standard dimensions. In the beam, an inner handle (1) is mounted on a main shaft (102) connected with a locking shaft (8A) on which there is mounted, against return springs (83), a door blocking/locking mechanism (8) comprising a lock (81). A mechanism for conditionally opening the door (100) includes a vent flap (110), a pivot connection (12) for coupling the flap (110) to the inner handle (1), and a blocking shaft (120) that has, at each end, a pressure lever (121) equipped with supports for blocking (122) and unblocking (123) the flap (110). Return springs (32) mounted against the conditional opening mechanism (100) are calibrated to allow the opening of the flap (110) by exerting reduced pressure in residual pressure variation conditions, and to prevent it from opening in overpressure conditions.

A portable stopper apparatus selectively attachable to a swinging door to releasably fix the door in an open position. The portable stopper apparatus may be positioned against a door that is open and desired to be mechanically held open in a space between the door and the door jamb and operates by preventing the space created by the door being opened from closing. The portable stopper apparatus is formed as a one piece structure that includes a planar portion, a bent portion that has a vertical extension panel, a horizontal extension panel, and a stopper panel positioned on three discrete planes, and a secondary member positioned between the vertical extension panel and the stopper panel.

A shelf supporting apparatus and a cooking appliance including a shelf supporting apparatus are provided. The shelf supporting apparatus may include a pair of fixing frames provided to face each other on opposite sides of a chamber which is opened and closed by a door; a pair of supports provided to have a length which is changeable in a frontward-rearward direction, the pair of supports being, respectively, coupled to the pair of fixing frames and having a shelf mounted thereon; coupling members provided on the pair of fixing frames and coupling the pair of supports to the pair of fixing frames to be position-changeable in the frontward-rearward direction; and a pair of connecting members that, respectively, connects the pair of supports and the door, and changing positions of the pair of supports in the frontward-rearward direction in conjunction with a rotation of the door.

An apparatus is provided having a foam cushion (9) attached to an elongate elastic member (8). Adhesive pads (10) are attached one to each end of the elastic member (8). A U shaped resiliently deformable handle is attached to the uppermost and lowest cushion (9) and adapted to project through the hinge gap formed between the hinge stile (6) and the door jamb (7) when the door is swung open. The apparatus can be secured to the hinge stile (6) of a hinge mounted door leaf (3) by means of the adhesive pads (10) and with the elastic member (8) under sufficient tension to keep the cushions resting against the hinge stile and the handle projecting through the hinge gap. If an attempt is made to close the door without displacing the cushions 9 from the hinge gap the cushions prevent full closure. To fully close the door the handle is pulled from the hinge side of the door, until the cushions (9) are displaced through the hinge gap and the door can then be closed. The cushions are too wide to pass through the reduced hinge gap when the door is closed. When the door is opened the spring force of the elastic member causes the cushions (9) to pull back through the widening hinge gap.

A stretchable adjustable-stiffness assembly includes a casing and first and second friction layers. The casing can be fluidly sealed and includes an interior compartment containing a fluid. The fluid can shift between a first interior pressure and a second interior pressure less than the first interior pressure and an exterior pressure. The first and second friction layers are disposed within the interior compartment. The assembly can shift between relaxed and fixed configurations. In the relaxed configuration, the fluid has the first interior pressure, the casing is stretchable between a first dimension and a second dimension greater than the first dimension, and the assembly has a first stiffness. In the fixed configuration, the first fluid has the second interior pressure, the casing length is fixed, the first and second friction layers are engaged, and the assembly has a second stiffness greater than the first stiffness.

A vehicular door device includes an inclinable lever provided at an open-side end portion of a door opening being opened and closed by a door, based on an operation of a link mechanism formed of first and second link arms, a biasing member that biases the inclinable lever and holds the inclinable lever in an erect state, and a check mechanism that engages with the inclinable lever in the erect state by movement of the door to a full opened position, and holds the door at the full opened position. The first link arm is provided at a position close to the open-side end portion of the door opening by an opening operation of the door, and the check mechanism is provided integrally with the first link arm. Then, the inclinable lever is stored in a clearance between the door and the open-side end portion of the door opening.

An oven includes an oven body, a heating element, a frame, and an oven door. The oven body has an inner space inside and includes a front plate, wherein the front plate has an entrance that communicates with the inner space. The heating element is adapted to heat the inner space. The frame is engaged with the oven body and has an abutted portion. The oven door is pivotally connected to the oven body and is located at the entrance. The oven door can pivot to a closed position to close the entrance and can pivot downward to an open position from the closed position to open the entrance. When the oven door is located at the open position, the second surface abuts against the abutted portion of the frame, thereby forming a platform outside the entrance for placing objects.

A contact-minimizing door opening and closing system for a door has a handle including a shaft with an endplate disposed on the shaft opposite the handle and a latch bolt including a pin positioned to contact the endplate. The pin prevents movement of the handle when the latch bolt is extended from a lock housing, and allows movement of the handle when the latch bolt is retracted into the lock housing. An engaging and disengaging mechanism couples the handle to a locking pin such that movement of the handle is configured to operate the engaging and disengaging mechanism to lock the door.
