Disclosed are a hinge and a refrigeration equipment. The hinge includes a vertical hinge shaft, a first hinge base and a second hinge base. The first hinge base includes a first installation plate and a first sleeve rotatably connected to the hinge shaft to make the first sleeve rotate around the hinge shaft. A lower end of the first sleeve is provided with a first slope sloping downwards. The second hinge base below the first hinge base includes a second installation plate and a second sleeve fixed on the hinge shaft. An upper end of the second sleeve is provided with a second slope sloping upwards. The second slope abuts against and cooperates with the first slope for the first sleeve to move from a first position to a second position along a direction away from the second sleeve or from the second position to the first position along a direction close to the second sleeve while being rotated around the hinge shaft.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body, wherein a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the door; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.

A door hinge comprising: a frame mount configured to be mounted to a door frame which is disposed about a doorway; and a door mount configured to be mounted to a door which is to selectively close off the doorway; wherein the door mount is pivotally connected to the frame mount about an axis of rotation, and further wherein the door hinge is configured such that when the frame mount is mounted to a door frame, and when the door mount is mounted to a door, the axis of rotation of the door hinge is disposed outwards of the point of attachment of the door hinge to the door frame, and laterally outboard of the doorway.

The present invention relates to security systems and methods for vehicles and/or vehicle users that prevent the theft of vehicles, and/or that guarantee the security of the vehicle user. In order to achieve the above, the system of the present invention has an enabling system that controls the ignition of the vehicle, and/or a device for helmets intended for the monitoring of the security of the user, and makes it possible to determine, for example, whether the user is wearing the helmet and is using the same correctly, or whether the vehicle user has suffered an impact. Specifically, the system of the present invention has an interactive system (mobile device) associated with the user which, depending on the need, signals the enabling system to enable the vehicle ignition, provided that at least one condition is fulfilled, where a condition may be that the interactive system is close to the enabling system and/or emits an alert message to the external device of a third party if any novelty is detected in the helmet device.

This present invention with the new added structure improvements to a single spring hinge for automatically keeping a toilet seat open and raised in an upright vertical position at all times.

the previous single spring hinge which a patent had already been granted by the U.S. PTO (Publication Number U.S. Pat. No. 4,751,765 A (Application Filed Number U.S. Ser. No. 06/938,604) which mainly utilizes the tension adjustment stand, made of metal or plastic composite material, to preserve the original intended functions,
the spring hinge which includes a first member, a second member, a spring, a spring seat, a tensile adjustment seat, a tensile adjustment pin, a shaft, and two holding heads.

The holding heads each include a hollow hat and a set of slots radially extending to form a set of claws fixed inside the hollow hat, the central portion of the slots being inwardly concave and an opening whose diameter is slightly smaller than the diameter of the shaft.

Thus, the shaft penetrating through the opening is pressed and secured by the claws so as to prevent any withdrawal of the shaft from the opening.

A multi-link hinge assembly includes first and second link levers, first and second sliding rods, first and second bases, a central shaft, and first and second torque shafts. The first link lever is connected to the second base by the second torque shaft and is slidable along with the first sliding rod within the first base. The second link lever is connected to the first base by the first torque shaft and is slidable along with the second sliding rod within the second base. The central shaft extends through the first and second link levers. When the second base is rotated relative to the first torque shaft, the first and second sliding rods move toward the central shaft.

The invention relates to a shoot boll assembly for mounting in a groove formed in a side edge of a panel, the assembly including a handle mechanism, a shoot bolt and a rod to connect the handle mechanism to the shoot bolt so that, actuation of the handle mechanism causes the shoot bolt to extend and retract from a top or bottom edge of the panel, wherein the assembly includes a hinge block arranged to fit in the groove, the hinge block having a deck with attachment holes for a hinge and fixing platforms that secure the block to a base of the groove, wherein a passage is provided beneath the deck and platforms for the rod to pass through. The invention also relates to a hinge block for the shoot bolt assembly, a folding panel system and a method of constructing a panel.
