Embodiments of the invention include an apparatus for positioning an electronic display. The apparatus can be combined with an existing work surface to provide a multi-position workstation. In some cases the apparatus includes a mounting portion configured to support an electronic display and a keyboard. The mounting portion may be movable with respect to the work surface between multiple positions, including for example, a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.

A method for building large-scale play structures having an ideal modularity is provided. The method includes providing panels having a thickness, a planar-quadrangle shape including a length, a width and four chamfered edges with a set of holes located along each edge, the holes located at a fixed interval relative to one another, the fixed interval providing a unit of length, a fixed-location fastening element located in each of the holes, respectively; providing a plurality of movable fastening elements each including a hand-grip to allow the respective movable fastening element to be moved between an unsecured position and a secured position without the use of tools when received by any one of the plurality of fixed-location fastening elements; and employing the fasteners to secure a plurality of the panels to one another to provide a structure that has an overall height, an overall length and an overall width, the structure including at least a pair of panels oriented one above the other and at least a pair of panels located at the same elevation and secured at right angles to one another.

A connecting structure for assembly includes a body, an inserting part, a latching part, and a control part. The body has a plug hole and a guide slot disposed toward the plug hole. The inserting part is detachably plugged into the plug hole correspondingly and has a latching portion. The latching part is slidely connected to and guided by the guide slot; the latching part has a latching body latched to the latching portion correspondingly. The control part is disposed movably in the body and selectively drives the latching part to reciprocate along the guide slot. Therefore, the esthetic effects of covering and hiding each other for assembled plates and the effect of a smooth, labor-saving, and even rotation for the control part are obtained.

A device for connecting two furniture parts, wherein the device comprises a housing arrangeable on a first furniture part and an eccentric element rotatably mounted in the housing. The housing is on one wall side flattened, and the flattened wall side of the housing has a continuous opening. The eccentric element is configured to cooperate with a connecting element, wherein the connecting element is arrangeable on a second furniture part, and wherein the connecting element can be coupled with the housing and the eccentric element such that the first and the second furniture part are fixedly connected to each other. The device is characterized in that the continuous opening in the housing on the flattened wall side is fully enclosed at the margin by wall portions.

A fastening device for fastening an object to a wall includes a fastening element, a bearing element adapted for bearing against the wall, and a holding element configured to hold at least a part of the object. The holding element has a through opening running at least through the holding element and the bearing element for allowing passage of the fastening element. A connecting element constructed as an eccentric connects the bearing element and the holding element to one another. The holding element together with the connecting element and the bearing element form a single-piece fastening unit.

The present disclosure provides a lock catch, a heat preservation plate assembly and a refrigerator. The lock catch comprises: a first lock catch portion, comprising a first housing and a first connection portion arranged in the first housing; and a second lock catch portion, comprising: a second housing, a surface of the second housing being provided with a first insert hole and a second insert hole; a rotary draw-bar assembly arranged in the second housing, the rotary draw-bar assembly comprising a draw-bar and a rotation portion arranged on the draw-bar, the rotation portion and the first insert hole being arranged oppositely, one end of the draw-bar being provided with a second connection portion matching the first connection portion, the other end of the draw-bar being provided with a fixed connection portion, and the second connection portion being connected to the first connection portion by means of the rotation portion driving the draw-bar to rotate, and a fixed shaft, arranged in the second housing and arranged opposite the second insert hole, the fixed shaft being locked tightly and fixed with the fixed connection portion by rotating a specified angle. The technical solution has the advantage of simple structure, convenient operation, and reliable connection.

A tool-less fastening system includes an interface assembly including an interface body having a first longitudinal end, a second longitudinal end, and a contact surface disposed between the first longitudinal surface and the second longitudinal surface, a fastening element coupled to the interface body, and a stop block extending from the interface body at the second longitudinal end, the stop block including an inclined surface. The tool-less fastening system also includes a receiver shaped to receive the interface body. The receiver has a receiver body defining a channel and at least one receiver block extending from the receiver body into the channel, wherein the at least one receiver block includes a receiving surface for receiving the contact surface of the interface body. In some embodiments, the tool-less fastening system can be implemented with shippable furniture, such as office chairs and tables.
