A cleaning device is provided that includes a handle, a cleaning implement, a flexible neck, and a collar. The cleaning implement depends from one end the handle. The flexible neck is positioned to allow flexion of the handle. The collar moves with respect to the flexible neck between a first position where movement of the flexible neck is unrestricted by the collar and a second position where movement of the flexible neck is restricted by the collar.

A football helmet includes a plastic shell with side regions having an ear flap with a face guard connector, an ear opening, a slot, and a snap connector. The helmet also includes an internal padding assembly removably connected to the plastic shell and including a jaw pad with a force attenuating layer. When the helmet is worn, a front edge of the jaw pad is positioned both in front of a coronal plane and below a basic plane of a head of the helmet wearer. A chin strap assembly releasably secures the helmet to the wearer and includes a lower flexible strap extending outwardly from each side of a central protective member. When the helmet is worn, an extent of the lower flexible strap is received by the slot when said strap is affixed to the snap connector. The shell also includes a raised central band integrally formed as part of the shell and extending across the crown region to the rear region. An arrangement of elongated vent openings flank the raised central band.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

The invention relates to a joint, in particular for use in a parallel kinematic positioning device, which has at least three rotational degrees of freedom, and which has a rigid carrier element and at least two elastically deformable joint devices arranged overlapping one another at least in sections on the carrier element, wherein each of the joint devices comprises two joint elements, and each of the joint elements has an elongated connecting section and a securing section arranged at one end of the connecting section for securing the joint device to a higher level unit, and the two connecting sections of each joint device extend in a direction pointing away from the carrier element in such a way that they cross over one another.

A flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings defined at least partially by a cantilevered extension portion. The flexural pivot can also include at least one flexure to rotatably couple the plurality of flexure support members to one another. The at least one flexure can have first and second flexible blades arranged in a cross configuration. The first and second flexible blades can be disposed in the flexure openings of the flexure support members, and the cantilevered extension portions, at least in part, can couple the first and second flexible blades to the flexure support members.

A bed comprises a fixed width deck section, a wing movably coupled to the fixed width section, and a rack and pinion mechanism for extending and retracting the wing.

The disclosure relates to a joint, which has at least three degrees of rotational freedom, having a rigid carrier element and at least two elastically deformable joint elements formed on the carrier element in an overlapping arrangement, at least in sections. Each joint element can include two rod-shaped web portions arranged on the carrier element and extending therefrom which are arranged either converging or diverging relative to each other, and at their end facing away from the carrier element are connected to each other by way of a contact portion. Two web portions connected to each other extend in a first common plane and two other web portions connected to each other extend in a second common plane, and the first common plane and the second common plane intersect.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

The technology disclosed provides a joint for connecting carrier units together so as to dissipate and absorb axial forces experienced by the carrier units. The joint may be comprised of a joint housing and an elastomeric insert. The housing may be comprised of a body portion and a head portion and the head portion may include an annular flange in which the elastomeric insert is configured to be secured. The elastomeric joint is capable of absorbing and dissipating horizontal, rotational, and vertical forces experienced by the carrier units in non-linear travel along a track.
