There is disclosed a double hinge module comprising a first rotary cam which is rotatable on a first shaft; a first coupling slot extended from one end of the first rotary cam in a direction which gets farther from the first shaft; a second rotary cam which is rotatable on the second shaft parallel with the first shaft in the reverse direction of the first rotary cam; a second coupling slot extended from one end of the second rotary cam which gets farther from the second shaft; and a link having one end coupled to the first coupling slot and the other end coupled to the second coupling slot, wherein when the first rotary cam and the second rotary cam are rotating, the link is linearly movable in parallel with a central line connecting the first shaft and the second shaft with each other, so that the double hinge module may fold the mobile terminal from 0? to 180? naturally like a book.

A hinge assembly includes a first and a second set of friction elements engaged each other by an applied force perpendicular to the friction elements. The first and the second set of friction elements are capable of rotational movement about a cylindrical element that passes through each of the friction elements. Also, the first set of friction elements is capable of movement relative to the second set of friction elements. However, the first set friction elements can remain in a fixed position based upon the applied force, until an external force overcomes the applied. During rotation of the first set of friction elements about the cylindrical element, the frictional engagement that controls the position of the first set of friction elements is based primarily on engagement between the friction elements, as opposed to engagement, if any, between the friction elements and the cylindrical element.

The present invention relates to a safety locking device for interlocking a safety door, having a movable part designed for being fastened to a moving part of the safety door, the movable part having a locking element, and a stationary part designed for being fastened to a non-moving part of the safety door. The stationary part comprises a receiving section, the receiving section comprising an opening for the reception of the locking element, wherein the locking element can be inserted into the receiving section from different insertion directions when the locking element is aligned in the insertion direction. The stationary part further comprises a latch, the latch being selectively movable from a locking position into a release position, wherein the locking element is secured in the receiving section when the latch is in the locking position and wherein the locking element can be withdrawn from the receiving section when the latch is in the release position. The safety locking device of the invention is characterized in that the locking element is secured in the locking position aligned in one of a plurality of different locking directions and in that the different locking directions comprise directions which together form a continuous angular range of at least 90?.

The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion that are rotatably coupled by a hinge assembly. The hinge assembly can include a hinge frame secured to the first portion and a hinge arm secured to the second portion. The hinge frame can be rotatably secured to the hinge arm by a band extending between a guide pin retained in the hinge frame and a friction pin secured to the hinge arm.

A hinge assembly including a flat plate and a bent plate is provided. The flat plate includes a first slot extending at least partially along a width of the flat plate and disposed substantially perpendicular with respect to a central axis of the flat plate. The bent plate includes a first portion, a second portion, and a third portion. The second portion includes a second slot extending at least partially along a width of the bent plate and disposed substantially perpendicular with respect to a central axis of the bent plate. The second slot is adapted to interconnect with respect to the first slot to pivotally move the hinge assembly between an open position and a close position. In the open position, the first portion of the bent plate is adapted to contact a first half section on a first side of the flat plate.

A pivot assembly adapted to an electronic device is provided. The electronic device includes a first device body including a first pivot side edge and a second device body including a second pivot side edge. The pivot assembly comprises a first pivot pivotally disposed inside the first device body, a second pivot pivotally disposed at the second device body, a first connecting member pivotally connected to the first pivot and the second pivot, a third pivot pivotally disposed at the second device body, a fourth pivot pivotally disposed inside the first device body, and a second connecting member pivotally connected to the third pivot and the fourth pivot. The third pivot is closer to the second pivot side edge relative to the second pivot. The fourth pivot is closer to the first pivot side edge relative to the first pivot.

Examples disclosed herein provide a hinge mechanism to couple housings of a computing device. As an example, the hinge mechanism includes a first guide rail fixed to a first housing of the computing device, a second guide rail fixed to a second housing of the computing device, and an intermediate guide rail to connect the first and second guide rails to each other. As an example, the hinge mechanism includes clamping brackets to hold the first, second, and immediate guide rails together and apply rotational friction to the hinge mechanism so that the first and second housings can be positioned at various angles with respect to each other.

An opening and closing mechanism includes a dead-center spring element for a swivelable part, and a control curve is provided on a side wall of the swivelable part, and the dead-center spring element engages the control curve via a swivelable control lever to control an opening and closing force progression with the aid of the control curve.

A counterbalance assembly including a housing, a pivot nose, and a spring pack. The housing including a front housing wall having a first housing edge and a second housing edge opposite the first housing edge, a first housing side wall projecting from the first housing edge and having a first retaining slot, and a second housing side wall oppositely disposed relative to the first housing side wall, projecting from the second housing edge and having second retaining slot in registered alignment with the first retaining slot. The pivot nose including a front pivot nose wall having a first pivot nose edge and a second pivot nose edge opposite the first pivot nose edge, a first pivot nose side wall projecting from the first pivot nose edge and having a first pivot nose through hole, and a second pivot nose side wall oppositely disposed relative to the first pivot nose side wall, projecting from the second pivot nose edge and having a second pivot nose through hole, the first and second pivot nose through holes are in registered alignment with the first and second retaining slot. The spring pack disposed within a volume formed by the housing and including a first end engaged with the housing, a second end engaged with the pivot nose, and an energy storage device arranged between the first and second ends.

A hinge module and an electronic device are provided. The electronic device includes a first body and a second body that the hinge module is connected therebetween, and the first and the second bodies are rotated to be folded or unfolded through the hinge module. The hinge module includes a guiding member, a first rail, a rotating shaft, and a linking member. The rotating shaft disposed at the first body in a rotatable and penetrating manner. The linking member is linked between the rotating shaft and the guiding member. The first and the second bodies are rotated relatively to each other via the guiding member and the first rail, and the guiding member drives the linking member to rotate the rotating shaft.
