An additive manufacturing method and an object manufactured thereby are disclosed. The object includes a first component and a second component pivotally connected to each other through a rotation shaft. A first engaging element of the first component and a second engaging element of the second component spatially correspond to each other. When the object is manufactured in a manufacturing space, the first component is close to the second component, and the first engaging element and the second engaging element are disengaged with each other. After the object is manufactured, the first component is rotated relative to the second component at an adjustment angle around the rotation shaft. The first engaging element and the second engaging element are engaged with each other and locked, to form a use space of the object larger than the manufacturing space. It is beneficial to achieve the purpose of reducing the required manufacturing space.

A door security device for an in-swing door includes a mounting plate secured to the door jamb adjacent the door outside edge, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a locking swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked angular positions in relation to the hinge pin vertical axis, the locking swing plate biased by force of gravity to a lowermost position, and the mounting plate having a first receiver wall defining the lowermost position of the locking swing plate in the locked position perpendicular to a first rear surface of the mounting plate and defining the uppermost position of the locking swing plate in the unlocked position away from the locked angular position.

A telecommunication device includes a main body to which a compartment is attached for receiving one or more components. A door is rotatable relative to the compartment between a closed position and a plurality of open positions. The door covers the compartment in the closed position. A connecting assembly attaches the door to the compartment, and includes a locking mechanism for preventing rotation of the door in a fixed position. The fixed position corresponds to an open position of the plurality of open positions. The locking mechanism self-locks in the fixed position when the door rotation reaches the fixed position.

A door security device for an in-swing door includes a mounting plate secured to the door jamb adjacent the door outside edge, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a locking swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked angular positions in relation to the hinge pin vertical axis, the locking swing plate biased by force of gravity to a lowermost position, and the mounting plate having a first receiver wall defining the lowermost position of the locking swing plate in the locked position perpendicular to a first rear surface of the mounting plate and defining the uppermost position of the locking swing plate in the unlocked position away from the locked angular position.

A cable release system configured to actuate a latch mechanism includes a cable arrangement configured to shift in response to an actuation force. The shifting of the cable arrangement is thereby configured to actuate the latch mechanism. The cable release system also includes a lockout mechanism configured to selectively impede shifting of the cable arrangement in response to the actuation force. Such selective impeding of the shifting of the cable arrangement is thereby configured to prevent actuation of the latch mechanism. A vehicle may employ the cable release system configured to actuate a latch mechanism to thereby unlatch a panel from the vehicle body.

[Object] To provide a hinge mechanism that allows a head-mounted display to be made more compact, and a head-mounted display including this hinge mechanism. [Solving Means] A hinge mechanism includes: a shaft portion; and a cable passing portion. The shaft portion supports a housing portion and a temple portion of the head-mounted display in such a way that the temple portion is capable of rotating about one axis between a closed position and an open position relative to the housing portion. The cable passing portion is adjacent to the shaft portion in a direction of the one axis, and allows a cable to pass therethrough in a direction orthogonal to the one axis.

A folding mechanism comprises a first folding body, a second folding body and a first clamping piece, the second folding body is provided with a second clamping piece, and the first folding body connected to the first clamping piece; and when the first folding body and the second folding body are unfolded, abutting parts of the first clamping piece are clamped in the second clamping piece, and a gap is formed between a non-abutting part of the first clamping piece and the second folding body. The first clamping piece connected to the first folding body is clamped in the second clamping piece on the second folding body to fix the first folding body and the second folding body when the first folding body and the second folding body are unfolded, and the gap is reserved to avoid shakes.

A system and method of a latching hinge system including a first leaf, a second leaf pivotally coupled to the first leaf, a coupler mounted on a first latch surface of the first leaf and a receiver mounted on a second latch surface of the second leaf wherein at least one of the coupler and the receiver has a corresponding orientation for latching the first leaf and the second leaf at a corresponding first angle.

A hinge structure includes: a supporting sheet having an unfolded, flattened state and a folded state; at least one first hinge connected to the supporting sheet, the at least one first hinge being configured to drive the supporting sheet to switch between the unfolded, flattened state and the folded state; at least one flattening support including a first support, a second support, and a flattening bracket, the flattening bracket being connected to the first support and the second support, the flattening bracket being connected to the supporting sheet. When the supporting sheet is in the unfolded, flattened state, the first support and the second support interact with each other and generate a force parallel to a plane where the supporting sheet is located, to maintain the supporting sheet in the unfolded, flattened state.

The invention relates to a hinge for a swinging door, the hinge has at least one hinge axis element, a first hinge part and a second hinge part which are connected to one another in a hinge-like manner via the at least one hinge axis element, at least one latching arrangement, which comprises at least one latching means arranged at the second hinge part and comprising a latching body, and at least one latching recess arranged at the hinge axis element, wherein the latching means is configured such that the latching body engages in the latching recess in a latching position, and a clamping means for releasably fixing the hinge axis element to the first hinge part, wherein an angular position of the hinge axis element and the latching recess with respect to the first hinge part can be adjusted. The clamping means comprises at least one pair of clamping jaws for clamping the hinge axis element between these clamping jaws, wherein each of the clamping jaws comprises a clamping surface adapted to the contour of the hinge axis element.
