A lock of the type generally described in European Patent Application No. 0070362, comprising a bearing housing, a holding member (100) and an eccentric pin (111), generally disposed and mechanically inter-related in the manner described in said application, the bearing housing having forwardly directed means adapted to extend through a slot (127) of a profile bar (128) or the like to which, in use, the lock is to be secured, and the holding member (100) having a hook element (102) at the forward end thereof; characterized in that the forwardly directed means is so configured as to provide a positive lock behind or around the slot (127) on the opposite sides of the slot (127) to that which the hook element (128) assumes when the lock is secured to the profile bar (128) or the like.

@ A channel connector for channel members, used in mechanical fastening systems for mechanically securing a flexible sheet relative thereto, each channel member being of generally rectangular form, in transverse cross section, and each channel connector being comprised of a flexible resilient material of a shape generally corresponding to that of the channel members and having bottom, side and top wall portions; transverse spacer means, having opposed sides, on the bottom wall, at about the midpoint of the channel connector axial extent; a channel connector bottom wall having a first aperture of a first predetermined size centered a first predetermined axial distance from one of the spacer means sides and a second aperture of a second predetermined size centered a second predetermined axial distance from the other of the spacer means sides.

The present invention refers to a group of elements for the realization of joints connecting and tightening two or more variously reciprocally oriented or orientable sections, whether tables, axes, laths, tubes or the like, variously oriented and orientable through the overlying association of at least two bodies, with coupling surfaces shaped to correspond to the surfaces of said sections to be joined, reciprocally fixed by at least one fixing and axial joint means, orthogonal to the directions in which each pair of sections is oriented; said joint means comprising two parts, associated respectively with said two bodies, complementarily fixable by means of a common bolt and allowing a continuous variability of the reciprocal angles between said bodies and a preestablished number of rigid angles between them, and so between the sections connected to them.

A clamp or connector 10 for an elongate member such as a pipe has a body 12 providing an internal bore having axially spaced inclined surfaces 16, 17, 18 respectively engageable by sets of angularly spaced balls 29 supported in apertures in a cylindrical cage 26 biassed axially by spring 28. In use the balls 29 engage a pipe 41 and annular seals 25, 34 engage the pipe. The apertures can be axially elongated to accommodate a degree of ovality in the pipe. One or more apertures have diverging walls to accommodate pipe ovality. Each ball may have a separate inclined surface; the spring can be omitted. There could be only one set of balls. The seal 25 could engage a taper on body 12 so as to move radially inwards when pushed axially. The clamp can be inside the pipe. Arrangements are described which include one or more seals for engaging the pipe.

A joint for connecting together framework members (10, 12) inside one of the members two arms (48) which protrude from one end of that member. The protruding portions of the arms have grooves (56) therein and teeth (66) beyond the grooves. The grooves and teeth face away from one another. The member (10) has a slot-like entrance (24) bounded by lips (20). With the protruding ends of the arms close together, the arms are inserted through said entrance, the lips entering the grooves and the teeth hooking behind the lips. A screw (88) passes through one of the arms and can be tightened to bear on the other of the arms to force them apart. A resilient clip (72) holds the other ends of the arms in place while simultaneously urging said one ends apart, the clip providing sufficient friction to hold the arms in position with respect to the lips. The arms are symmetrical in form with a tooth and groove at each end so that when the resilient clip (72) is removed, the arms are usable for connecting two parallel members.

Solidarisation de deux éléments linéaires devant former un angle entre eux. Le dispositif comprend deux embases 1 et 2 réunies par une charnière 11 et munies d'un canal transversal respectivement 3 et 4. Après avoir plié la charnière 11, les embases sont l'une contre l'autre et les éléments à solidariser A et B sont pressés directement l'un contre l'autre, le tout est maintenu "fermé" par des boutons 12 engagés à force dans des trous 13. Réunion de tiges et tuteurs pour plantes ainsi que d'armatures pour le béton.

A lock of the type generally described in the German Patent Application No. 3128595, comprising a bearing housing, a holding member (100) and an eccentric pin (111), generally disposed and mechanically inter-related in the manner described in said application, the holding member (100) having a slot (106) through which extends the journal (113) of the eccentric pin (111); characterized in that the slot (106) is so configured as to ensure that inadvertent rotation of the pin (111) beyond the normal locking position is avoided.
摘要:
A rest structure supported by support elements, on which to lie and/or sit, with or without interposing mattresses and/or cushions, formed from a succession of hollow rod-shaped bodies (1) disposed parallel to each other and sustained on cross-members (2) which intersect them and to which they are removably connected by couplings inserted in said rod-shaped bodies.
