A joint ring of an endoscope comprises a joint ring body including a joint ring wall having an inner surface, an outer surface, a first end surface, and a second end surface, and a first wire guide attached to the inner surface of the joint ring wall. The first wire guide includes a first wire guide body including a first wire guide wall having a third end surface and a fourth end surface. In a central axis direction of the joint ring body, at least a first portion of the first end surface and at least a first portion of the third end surface are at a first axial position and at least a first portion of the second end surface and at least a first portion of the fourth end surface are at a second axial position.

A coupling for connecting a circuit board to a mount with a fastener. The mount may be connected to a component. The fastener includes a first snap-fit connection formation for establishing a snap-fit connection with a second snap-fit connection formation provided on the mount. When connected, the fastener clamps the circuit board against the mount. The fastener further includes a first engagement formation configured to engage with a second engagement formation on the mount for bracing the snap-fit connection.

To provide a fitting member, an annular member, a joined member and a method of manufacturing the joined member, which prevent occurrence of a not-joined portion. A fitting member 10 has a fitting protrusion 10p which is protruded outward on an outside face 10s. An annular member 20 contains a space 20h in which the fitting member 10 is to be fitted. An annular member 20 has an annular protrusion 20p on an inside face 20f. When the fitting member 10 is fitted into the space 20h at a predetermined depth, the fitting protrusion 10p and the annular protrusion 20p fill not-joined portions which may be generated assuming that they are not provided. A joined member 30 is produced by fitting the fitting member 10 into the space 20h at the predetermined depth, so that a contact portion between the fitting member 10 and the annular member 20 is joined in solid phase.

A quick disconnect mount includes a mounting stud securable to a structure, and a connector securable on the mounting stud. The mounting stud includes at least one circumferential ridge and at least one circumferential trough, and the connector includes a central channel sized to fit over the mounting stud and a locking bar engageable with the circumferential trough.

A locking rail for locking of a first and a second panel horizontally. The panels each include an essentially vertical panel surface and an essentially horizontal edge surface. The locking rail includes a first and a second locking device which are configured to engage the edge surface of the first and the second panel, respectively, and an interconnecting extension which extends between said first and second locking device. The first and second locking device each includes a first locking tongue which extends essentially perpendicular to the interconnecting extension. The first locking tongue of the first locking device is configured for locking of the first panel in a first horizontal direction and the first locking tongue of the second locking device is configured for locking of the second panel in the first horizontal direction. The locking rail includes a first locking part which extends essentially perpendicular to the interconnecting extension.

Apparatus, systems and methods for providing one or more accessories on a support surface include a base releasably engageable with the support surface, a housing configured to carry at least a first accessory and be releasably engaged with the base and an elongated carrier rod configured to carry at least a second accessory and be releasably engaged with the base.

An angle bar includes two longitudinal angled plate portions, and a corner portion connecting therebetween. The corner portion has an inner corner surface bounding an inner corner space and an outer corner surface. A stopper protrudes into the indented corner space, and has an abutment face extending across the indented corner space. A limiter protrudes into the indented corner space from the inner corner surface, and has a through hole opening in a direction along a bending line of the corner portion. A modular post assembly has at least two angle bars abutting each other, and a fixing rod extending through the through holes of the bars along the bending line and limited between the stoppers for fixing together the bars.

The locking rail includes a first locking part which extends essentially perpendicular to the interconnecting extension.

Disclosed herein are an air bag type magnet holder, a method of manufacturing and a method of use. The air bag type magnet holder comprises a magnet outer base, an inner base for being attached or attracted to the back of a mobile phone, and an expandable air bag with an expanding and contracting function arranged between the magnet outer base and the inner base, and the magnet outer base comprises a lower shell connected to a second end of the expandable air bag, a metal plate fixed to the bottom shell and facing one side of the expandable air bag, and a plurality of magnet inserts embedded in the lower shell and attached to the metal plate. The attractive force of the magnet inserts is utilized to attract the magnet holder onto an external metal-containing article creating a new level of mobility for the user over other phone grips on the market.
