A releasable lock (11) for a pipe cradle is disclosed. The releasable lock (11) comprises an elongate arm (1), pivotally secured at a first end to a pivot end mounted on a cradle frame (12). At a second end the releasable lock comprises a locking element (3), said locking element (3) being moveable between a release position allowing pivoting of the elongate arm (1) about the pivot end and a gripping position preventing said pivoting. The pivot end is moveable about a pivot pin (10) housed on the cradle, said movement displacing the elongate arm (1) between a first release position allowing removal or addition of pipes (15) from/to a cradle and a second position in which pipes are secured in position in the cradle.

Disclosed embodiments relate to devices and methods for storage and/or transport of tubular structures, such as perforating guns for use in wellbores. Some embodiments relate to modular storage containers, for example which may be height adjustable depending on the length of the tubular structure to be held therein. Some embodiments relate to mobile storage banks, which may be configured for use with the modular storage containers. In some embodiments, the storage bank may further be configured with one or more longitudinal compartments configured to hold used tool strings or portions thereof.

A ball, sphere or article holding system includes a first hollow semi-hemisphere or shell formed of a resilient material and having therein a plurality of apertures, the semi-hemisphere or shell including a first hinge element and, diametrically opposed, a first selectable closure element. The system also includes a second hollow semi-hemisphere or shell formed of a resilient material and also having a plurality of apertures, the second semi-hemisphere or shell including a second hinge element which is complementally proportioned, disposed and engagable relative to the first hinge element. Diametrically opposed therefrom is a second closure element which is complementally and press or snap-fittably engagable by the opposing closure element of the first semi-hemisphere or shell. Closure between the responsive closure elements may be enhanced by the use of a ring slip-fittably passing between complementally disposed apertures within and between the closure elements. The surface of an article held within the system is offset from interior surfaces of the semi-hemispheres or shells by nubs, stubs of the like. Articles held within the sphere may include bells and treats for pets.

Provided is a utility box, which includes a first compartment. The first compartment includes a first angled floor and a first holding unit configured to hold an article in the first compartment. The utility box also includes a first lid that covers at least the first compartment.

The purpose of the present disclosure is to provide a battery accommodation tray in which the amount of material used is readily reduced and of which the strength is readily improved. The battery accommodation tray comprises a plurality of accommodation parts that respectively accommodate batteries and that are positioned at intervals from each other. The accommodation parts have insertion openings demarcated by insertion-side circular parts that have a circular shape when viewed from the insertion side of the batteries in the height direction (Z direction). The battery accommodation tray has insertion-side connection parts by which the outer peripheral surfaces of the insertion-side circular parts are connected to the outer peripheral surfaces of adjacent insertion-side circular parts. The plurality of insertion-side circular parts are connected by the plurality of insertion-side connection parts to form an integrated whole.
