In some examples, an apparatus can include a base plate to interface with a printing device, where the base plate includes an extension member having a pawl, and a lock ring, where the lock ring includes a blocking key, where the lock ring is to interface with the base plate such that the blocking key prevents rotation of the extension member to lock the base plate to the printing device.

A push-on fastener includes a base, a first radial barb, an axial support, a second radial barb, and a protrusion. The base defines an opening. The first radial barb extends from the base. The axial support extends from the base. The second radial barb extends from the axial support. The protrusion extends from the axial support.

A connection assembly includes first and second components joinable along an axis of relative movement, starting from a separated disassembled state, into an interconnected assembled state, and transferable back into the disassembled state. The first component has a latching element and the second component has a latching element receptacle which cooperates with latching portions of the latching element in the assembled state. The latching portions are offset relative to each other when viewed in a circumferential direction, and are each movable along a movement path starting from a non-deformed rest state. A first portion of the movement path points in a disassembly direction, and a second portion of the movement path points in an assembly direction opposite the disassembly direction. The first portion of the movement path is limited by a stop against which the latching element rests in a course of disassembling the components.

The present invention relates to a tensioning bracket (1) for tensioning at least one perforated band (6) defining a longitudinal band axis (15), the bracket comprising at least one bracket element (2) having a thickness and comprising a first body section (3) defining a first longitudinal body axis, a first body width, and the first body section comprising a number of projecting pins (11) arranged to receive the perforations (7) of the band, the projecting pins identifying a pin side and an opposing non-pin side of the bracket element, and a second body section (4) defining a second longitudinal body axis, a second body width comprising a number of holes (12) arranged in the same pattern as the projecting pins of the first body section, and the bracket element further comprising an attachment section (8) for attaching means for pulling and thereby tensioning the perforated band, wherein the first and second body sections are connected to each other via a common section (5) made of the same piece of material as the first and second body section and wherein the bracket element is configured so that when bending the element along a bending line in the common section the pins of the first section are received in holes of the second body section.

The autonomous travel working machine includes a working body unit, a cover unit, and a connecting structure unit connecting the working body unit and the cover unit. The connecting structure unit includes a body connecting section attached to the working body unit and a cover connecting section attached to the cover unit. When the cover unit is lifted, a shaft portion of the cover unit is slid upwardly with respect to a head portion of the working body unit so that the cover unit is moved upwardly or lifted with respect to the working body unit. When the working machine hits against an obstacle, an intermediate portion of the body connecting section is resiliently deformed in a lateral direction so that the cover unit is moved with respect to the working body unit substantially only in the lateral direction.

A captive screw, comprising: a screw; a press fit nut, to connect to an opening on a device and to accept a screw, including: a bottom portion, to extend through the opening; a top portion; and a middle portion, wherein the middle portion is smaller in circumference than the top portion and the bottom portion; and a sleeve including a protrusion, wherein the sleeve fits over the screw and attaches to the press fit nut via the protrusion.

A connector having a head that holds a first component and a body connected to the head. The body has a central channel extending along a central axis of the connector, and the central channel receives a fastener. The body has at least two resilient legs. The resilient legs extend obliquely toward the central axis in a direction from the body to the head. The at least two resilient legs engage with the fastener, to attach the connector to the fastener.

The present disclosure provides a fastening assembly for attachment of a component. The fastening assembly is self-locking, and comprises a housing that presents a barcode, and a retention clip that is configured to form an interlock with the housing and is changeable between an open configuration adapted to freely receive a component, and a closed position adapted to capture and retain the component. The retention clip is slideably moveable within an aperture of the housing between an initial position, in which the retention clip is in the open configuration and the barcode is unreadable, and a final position, in which the retention clip is in the closed configuration and allows for the barcode to be read or scanned to verify installation of the fastening assembly on the component.

A lock for holding a first part to a second part comprises a holding body with a receptacle for receiving a protruding part of the second part. The holding body having has a wall that borders the receptacle and a locking element, the locking element having a protrusion, whereby the locking element has a first position, whereby in the first position the protrusion is in a locking position, whereby in the locking position the protrusion protrudes from the wall into the receptacle by a first amount and the locking element has a second position, whereby in the second position the protrusion is in a release position, whereby in the release position the protrusion either protrudes from the wall into the receptacle by a second amount, whereby the second amount is smaller than the first amount, or the protrusion does not protrude from the wall.

An anchor assembly for wall installation includes a toggle body that is elongated along an axis, and a strap connected to and extending from the toggle body, wherein the strap includes a main segment that extends in a first direction away from an axis of the toggle body when the strap and toggle body are in an unstressed state, and the main segment is bendable down toward the toggle body such that the main segment extends in a second direction, where the second direction runs more closely to parallel with the axis than does the first direction. A locking sleeve mounted for movement along the strap toward the toggle body. The strap is substantially L-shaped and includes a small segment extending laterally relative to the main segment, wherein the small segment is seated within a recess on the toggle body.
