A portable support for supporting equipment above a surface having an opening to a subsurface space. The support includes a head, an elevator on the head, and legs connected to the head for supporting the head above the surface. Each of the legs has a foot for engaging the surface when supporting the head above the surface. The support also includes an elongate rod vertically mounted on the elevator for movement between a raised position, in which an upper end of the rod extends above the head, and a lowered position, in which a lower end of the rod extends below the feet of the legs to extend into the subsurface space. The support includes an instrument platform positionable on the lower end of the rod when in the lowered position to support the equipment in the subsurface space when the rod is in the lowered position.

A spacer plate (3, 6, 7) for interconnecting support profiles (1, 5, 8, 9) of a display support structure (23) is described, including at least one alignment opening (11) for receiving an alignment stud (2) for aligning a first profile (1, 8) with respect to a second profile (5, 9) via the spacer plate (6), and at least one connector opening (13) for receiving a connector bar (4) for connecting the first profile (1, 8) to the second profile (5, 9) via the spacer plate (6), wherein the connector opening (13) is connected to the alignment opening (11) such that the relative position of the alignment stud (2) inside the alignment opening (11) is adjustable by the position of the connector bar (4) inside the connector opening (13). This allows to easily put the alignment stud (2) into the alignment opening (11) of the spacer plate (3, 6, 7) or vice versa and to eliminate all free play between the alignment stud (11) and the spacer plate (3, 6, 7) at the same time. The assembly of the support structure (23) is not hampered. At the same time a self centering of the alignment stud (2) with respect to the spacer plate (3, 6, 7) can be forced leading to an increased accuracy, when the profiles (1, 5, 8, 9) are connected to each other.

A piece of furniture comprises one or more furniture parts as well as one or more furniture fitting elements which are connected to the furniture parts via attachments. At least one of the attachments is formed by, on the one hand, an opening in the wall of the respective furniture part, wherein this opening is provided with at least one collar, and, on the other hand, a single- or multi-part attachment element which works in conjunction with the respective furniture fitting element and which can be provided in the opening. The attachment element is provided with one or more locking parts which engage behind the collar or collars.

A feather imping pin with roughened surface is described that attaches a donor feather to a receiving feather. The feather imping pin is inserted into a receiving feather shaft of the receiving feather. Feather imping is performed using the feather imping pin that connects the donor feather and the receiving feather. The feather imping pin fits inside both the receiving feather shaft of the receiving feather and a donor feather shaft of the donor feather.
摘要:
A device for the forced locking of two elements oriented orthogonally to one another, especially suitable for steadily connecting and constraining two tubular elements (10), (12) with quadrangular or polygonal section which are partly delimited by a U-shaped band (22) and which have, on at least one face, a plurality of pairs of shaped recesses (14), whereas the band (22) is correspondingly provided with pairs of complementary projections (16) developed projecting on the inner front of the opposite vertical and parallel branches (18) and (20) thereof. The device further includes a bush (32), extending between the branches (18) and (20) of band (22) and fitted, at one end, on a collar (28) which develops projecting along the inner front of branches (18) and (20), whereas the opposite end of bush (32) constitutes the inlet for a screw (30) the end whereof engages in a threaded hole (28′) delimited by the collar (28), bush (32) being extended transversally in the tubular element (10) or (12), provided with aligned holes (38), (40) along two opposite faces, starting from a hole (26) of the band (22).

摘要:
A separable or collapsible golf club, comprising a first shaft member and a second shaft member, which are secured together by means of a connector having two or more biased releasable ring-shaped fasteners positioned apart from one another to provide counterbalanced engagement, to afford an interconnection of the shaft members to form a single golf club when assembled, but that allows for prompt disconnection, through the remote actuation of the fasteners, when the golf club members are to be separated or collapsed, or a different club head is to be installed for usage and application for driving or putting of a golf ball.

The present invention discloses a board fixing module for fixing a board to a base body. The board fixing module includes: a fixing element embedded into the base body, a bottom portion passed through the board and a latch element latched with the fixing element, and a passing rod passed into the latch element for maintaining the latch condition of the latch element and the fixing element. The invention is characterized in that users simply need to press the passing rod inward to release the latch condition of the latch element and the fixing element in order to separate the board from the base body, and thus the invention achieves the effect of a convenient installation or dismount.
