A shelf attachment for use with a beach or lounge chair is formed of one-piece or has a first shelf half and a second shelf half hingedly and foldably connected to the first shelf half. An elongated member extends through interlocking projections extending from the first shelf half and from the second shelf half to hingedly connect the first and second shelf halves. A first clamp assembly is secured to the first shelf half and a second clamp assembly is secured to the second shelf half to mount the shelf to the rail of a chair.

First and second U-shaped cross-members each have legs connected by cross bars and pivotally connected with each other at central portions thereof, and are mutually movable from a generally X-shaped setup condition in which the cross bars are transversely spaced apart, to a generally flat collapsed condition. Right and left frame side assemblies respectively are pivotally connected to the first and second cross-members at terminal ends of their respective front and rear portions and by at least one lost motion linkage.

The invention relates to an adjustable and dismountable arm rest, to allow a person to rest their arms for extended periods of time, in order to provide the arm with stability when holding objects that require precision such as binoculars, photography cameras, video cameras or other equipment and/or accessories, of a determined weight which tires the arm while observing in inhospitable areas in order to capture the behaviour of a determined event, for example a flower opening, the behaviour of animals, inter alia. The arm rest according to the invention comprises only 5 elements that can be assembled and disassembled: a first vertical post and a second vertical post which are fixed temporarily at the upper end thereof to a first horizontal crossmember, and the lower end of both vertical posts is temporarily fixed to a second horizontal crossmember. The first and second horizontal crossmembers consist of a rectangular prismatic body, the widest section of which is arranged perpendicular to the vertical posts, and has, on each end, an assembly of perforations that pass through the thickness thereof, are at an equal distance from each other, and are coincident in terms of the number thereof. The first crossmember has two grooves in the centre, parallel to the length thereof, and the second horizontal crossmember has one groove in the centre, via which grooves a strap is inserted, which allows temporary fastening between the horizontal crossmembers when the support is assembled.

Provided is a storage mechanism for a seat table enabling improved handleability at the time of storage with a relatively simple configuration. One aspect of the present disclosure is a storage mechanism for a seat table used by combination with a seat. The storage mechanism for the seat table includes a held portion provided to the seat table, and a holding portion provided to a storage portion where the seat table is stored. The held portion includes at least one attracted magnet. The holding portion includes at least one attracting magnet attracting the at least one attracted magnet, and at least one repelling magnet repelling the at least one attracted magnet.

A coupling arrangement for two panels (12, 13) that are movable relative to one another may include comprises a first and a second guide track; (1, 2) and a first and a second guide pin (5, 6) for engaging in the guide tracks (1, 2). The first guide track describes a straight path having a starting point and an end point. (E1), and the The second guide track describes a first straight section which is arranged parallel to the first guide track, a circle section and a second straight section which extends parallel to the first guide track. In the case of a piece of furniture having a first panel and a second panel, the panels are coupled together with the aid of a coupling arrangement such that, from a starting position of the panels (12, 13), a guided translation (T1, T2) and a guided rotation of the panels (12, 13) with respect to one another can take place in succession.

A double heated recreational chair includes a pair of chair frames and a table top tray pivotally and swivelly carried by the chair frame. The chair frame is selectively deployable in a folded, collapsed configuration in which the table top tray is deployed in a folded position adjacent to the chair frame. The chair frame is selectively deployable in an extended, functional configuration in which the table top tray is supported on the chair frame in a generally horizontal position.
