A mold holder device in a press brake includes a mold clamp that clamps a mold with respect to a mold contacting surface provided for a holder body of the mold holder device. The mold clamp is pivotally arranged on the holder body. A long groove is formed in a mold clamping surface with which the mold clamp clamps the mold with respect to the mold contacting surface. The long groove is in parallel with a pivot axis of the mold clamp. A metal pipe member has a longitudinal slit and is inserted in a rotation restricted state into the long groove. A part of an outer peripheral surface of the pipe member is protruded toward the mold contacting surface.

A device for securing one or more units includes a first component and a second component configured to couple to the first component. The first component includes a body that has an elongated shape and a head that is connected to an upper longitudinal end of the body. The head includes a part that is configured to be rotationally engaged by a tool. The first component also includes a retainer at a lower longitudinal end of the body. The first component further includes an elastic latch formed in a thickness of the body. The elastic latch includes a tab that has an upper end connected to the body and a free lower end. The elastic latch is configured to cooperate with complementary means of one or both of the second component or the one or more units.

A kit is provided that, when assembled, forms a unit of furniture. The kit includes side panels that can reversibly slide into an opening formed in the sides of the front and side panels. The kit may include multiple locking pins to restrict movement of the top and side panels. The kit may include positioning wedges and/or locking wedges to restrict relative movement of the panels and thus improve the stability of the unit. Also provided are methods of assembling the unit of furniture.

A fastener includes a head configured to be anchored to a part, and a locking member extending from the head to a distal end, the locking member including at least one protrusion spaced from the head, and a tool engaging head at the distal end, wherein, in use, the locking member extends through an opening of a panel such that the head is retained on a first side of the panel, the distal end is disposed on a second side of the panel, and the at least one protrusion abuts the second side of the panel to secure the panel to the fastener; and wherein the fastener includes a resiliently deformable portion arranged such that rotation of the tool engaging head deforms the resiliently deformable portion and moves the at least one protrusion out of abutment with the second side of the panel to release the panel from the fastener.

An attachment mechanism is configured to maintain connection between a first pet component and a second pet component. The attachment mechanism includes an elongated body, a first stop, and a second stop. The elongated body includes a stem having a stem width. The first stop is disposed adjacent an end of the elongated body and has a first width. The second stop is disposed on the elongated body and is spaced from the first stop. The second stop has a second width. The first width and the second width are larger than the stem width. Each of the first stop and the second stop is configured to limit removal of the second pet component from the first pet component.

A device for securing a first unit to a second unit includes a first component having a body and a head. The body is configured to be inserted in at least one of a first orifice of the first unit and a second orifice of the second unit. The first component includes a retainer at a lower longitudinal end of the body. A second component is configured to couple to the first component. At least one of the first and second components includes at least one cam surface and the other of the first and second components includes at least one follower configured to cooperate with the at least one cam surface, and to transform a rotational movement of the first component into a longitudinal translation movement of the first component in relation to the second component so that the retainer bears on the lower surface of the second unit.

An improved panel fastener assembly is provided and includes a panel retainer having a first connector and a sheet retainer having a second connector. One of the connectors includes a neck extending to a head that presents a flat face opposite the neck and a contact surface between the neck and an outer edge. The other connector includes a body and a plurality of resiliently deflectable locking elements that each extend from a side of the body and define a locking surface opposing a surface of the body. The panel retainer and the sheet retainer are connectable via the first and second connectors. A method of fastening together a panel and a sheet is also provided. The method comprises installing the panel retainer on a panel, anchoring the sheet retainer to a sheet, and connecting together the panel and sheet retainers via the first and second connectors.

A method of inserting a pin in a bore of an article may include first providing an article with a bore, the bore having an inside diameter. The method may then include providing a pin having a hollow body, the hollow body having a diameter with a profile with a pattern of voids. The method may then include applying an axial force on an end of the hollow body to cause the diameter of the pin to reduce in size to a point where the diameter of the pin is less than the inside diameter of the article. The method may further include aligning the pin inside of the bore of the article, and then removing the axial force on the end of the hollow body.

A locking push pin and methods of using the locking push pin to assemble a heatsink assembly, are described. The locking push pin includes a body lumen extending through a pin body, and several prongs radially outward from the body lumen. Peripheral surfaces of the prongs are separated by a body slot radially outward from the body lumen. The locking push pin includes a pin lock having a branch that extends through the body lumen and into the body slot between the peripheral surfaces. The pin lock advances from an unlocked configuration in which the branch is in the body slot proximal to a distal end of the prongs, allowing the prongs to deflect radially inward, to a locked configuration in which the branch is in the body slot at the distal end of the prongs, blocking deflection of the prongs. Other embodiments are also described and claimed.

A kit is provided that, when assembled, forms a unit of furniture. The kit includes side panels that can reversibly slide into an opening formed in the sides of the front and side panels. The kit may include multiple locking pins and cleats to restrict movement of the top and side panels. The kit may include positioning wedges and/or locking wedges to restrict relative movement of the panels and thus improve the stability of the unit. Also provided are methods of assembling the unit of furniture.
