An interlocking hinge is described. The interlocking hinge includes a first hinge member and a second hinge member. The first hinge member and the second hinge member interlock in a separable engagement.

A fabric treatment machine has a cabinet housing. A lid enables access inside the cabinet. Fabric treatment components such as a drum are positioned inside the cabinet housing. A panel on the cabinet housing includes an opening to receive the lid. At least one hinge spacer couples with the panel to receive a shaft of a slow close hinge on the lid. The at least one hinge spacer includes a socket portion and a flange portion. The socket portion inserts into an aperture in the panel. The socket portion includes a bore with at least one flat side to receive a mating shaft from the slow closing hinge. The hinge shaft has at least one flat surface. The flange portion covers the panel around the socket.

Embodiments of the present invention provide improvements to printers including the use of engineered structures to limit bending, flexing, and/or twisting during impacts and the use of impact absorbing materials to prevent cracks and breaks. Design features and materials add to the rigidity of the printer design to prevent twisting and flexing during impacts and add to the strength of the printer design in typical breakage areas. For example, embodiments provide improvements that strengthen traditional break areas by the use of improved materials and design optimization to distribute impact forces. Embodiments allow the printer to maintain an operational status following a drop test and/or a tumble test.

A fixing structure of a door body shaft bushing includes a door body outer frame, a door body inner frame engaged with the door body outer frame, a door body shaft bushing arranged between the door body outer frame and the door body inner frame, and a plurality of reinforcing ribs arranged on two opposed surfaces of the door body outer frame and the door body inner frame when the door body outer frame and the door body inner frame are engaged with each other. The plurality of reinforcing ribs are respectively arranged in a staggered manner along a radial direction and an axial direction of shaft holes of the door body shaft bushing. The reinforcing ribs on the door body outer frame and/or the door body inner frame are in contact with the door body shaft bushing and clamp the door body shaft bushing.

The description relates to hinged devices, such as hinged computing devices. One example can include a hinge assembly that rotatably secures a first portion and a second portion relative to a hinge axis and defines a planar conductor path between the first and second portions through the hinge assembly. The example can also include a pop-up arm that compresses a spring when the first portion and the second portion are rotated to a closed orientation, and wherein the compressed spring creates a bias to rotate the first and second portions from the closed orientation to an open orientation.
