DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0028] FIG. 1 shows the chair as a mobile piece of furniture 1 with a leg 2 and with a number of support struts 3, 4 joined with this by plug connections, as well as with a flexible, for example fabric, covering 5. This is put onto the free ends 7 opposite the joint ends (FIG. 2) of the support struts 3, 4 in the shown assembly position by means of holding pockets 6 at the corners, thereby forming a seat surface 5a and a back surface (back rest) 5b as well as two lateral covering surfaces 5c. In the embodiment example, the leg 2 comprises three foot elements 2a that are hinged swivelably onto a central holding element 2b.

[0029] The support struts 3, 4 run diagonally upward and outward in the shown assembly position, where in FIG. 1 an angle of inclination from the vertical V is less than a set-up angle corresponding to the 90 angle from the horizontal H. The seat and back surfaces 5a, 5b are specified in a practical way from the length and inclination of the support struts 3, 4.

[0030] As illustrated in FIG. 2, the support struts 3, 4 for the flexible covering 5 are each composed of at least two partial struts 3a, 4a, in that they are pluggable into the ends of each other in the longitudinal direction of the struts. To this end, at least some of the partial struts 3a, 4a exhibit plug shafts 3b and 4b on their ends. These are locked in a detachable way into corresponding bushing-, collar-, or sleeve-shaped plug-in sections 3c and 4c of a partial strut 3 and 4 that are adjacent in the longitudinal direction of the strut, while producing a corresponding joint.

[0031] To stabilize the swiveled foot elements 2a of the leg 2 shown in the assembly position, a rope- or band-type connection element 8 can be prepared that is pulled tight in a star or spider web pattern with the foot elements 2a. To this end, these exhibit corresponding joints at a suitable position, as needed, to which the connection ends 10 of the connection element 8 can be attached. A central surface element 11 in the neutral point of the star-shaped connection element 8 in the embodiment example offers an additional contact surface so that additional protection from the leg 2 or its foot elements 2a sinking into a soft, sandy, or granular surface is provided when making the intended use of the mobile chair or piece of furniture 1.

[0032] FIGS. 3 through 5 show different representations of the leg 2. In the design according to FIG. 3, the central holding element 2b is recognizable from a number, which corresponds to the number of foot elements 2a, of, for example, curved single-piece partial segments connected with each other, and the foot elements 2a are formed with a smooth surface on the outside, while the central holding element 2b is embodied as discs in the embodiment example according to FIGS. 1 and 2, and the foot elements 2a are provided with surface structures running in the longitudinal direction of the feet.

[0033] In principal, however, the foot elements 2a of the leg 2 are formed in a bowl shape so that a concave or interior space 12 is created when leg 2 with foot elements 2a swiveled against each other on the inside of the leg 2 is in the folded position shown in FIGS. 4 and 5. The support struts 3 and 4 that have been collapsed into partial struts 3a and 4a, as well as the covering 5, and, if applicable, the connection element 8, can be moved into this interior space 12 of the leg 2 so that the leg 2 takes on the additional function of packing the piece of furniture composed in the embodiment example as a chair in the folded position. The strut length of the partial struts 3a and 4a has been adjusted here to the length L drawn in FIG. 5 of the foot elements 2a and concave space 12 of the leg 2.

[0034] The swivelability of the foot elements 2a of the leg 2 opposite the central holding element 2b is produced by articulated joints 13. To this end, joint heads 14 are shaped to the foot elements 2a on their foot ends facing the holding element 2b, which are seated on joint pins 15 of the central holding element 2b. In order to block the swiveling of the foot elements 2a beyond a maximum swiveling angle from the central axis from vertical V of the leg 2 as illustrated in FIG. 3, stops or stop contours (joint stops) 16 are provided for on the holding elements 2b. In the embodiment example, these are formed by at least partially circumferential arch-shaped indented collar contours 13 oriented against the joint connections, which engage the groove-shaped and correspondingly arched recesses or seat contours 17 of the joint heads 14 of the foot elements 2a, while the foot elements 2a swivel outward. The maximum swiveling angle is specified by the positioning of corresponding groove bottoms 18 of the groove-type recesses 17 of the joint heads 14, and when the maximum swiveling angle is reached, further swiveling of the foot elements 2a is reliably blocked.

[0035] The leg 2 exhibits a number, which corresponds to the number of support struts 3, 4, of collar- or sleeve-type plug openings 19 to produce the joints while mounting the support struts 3, 4. In the embodiment example, these are inserted into these at the joint end of the foot elements 2a on the outside and are designed like a bushing. This ensures the secure seating of the support struts 3, 4 in the leg 2.

[0036] To form the concave or interior space 42 within the leg 2, the legs 2a are formed at least on the inside with a correspondingly arched interior wall 20 (FIG. 3), which are complemented by an at least partially closed, preferably cylinder-shaped, interior wall when the foot elements 2a shown in FIGS. 4 and 5 are in the swiveled-in position.

[0037] FIGS. 6 and 7 show a variant of the mobile piece of furniture embodied as at chair with, again, a leg 2 and support struts 3, 4 that are joined in a removable way with the leg 2 as well as with a seat and back covering 5 that are put onto the strut ends 7 of the support struts 3, 4 using the pocket-type holding elements 6 and is thereby held onto these in a detachable way. The support struts 3, 4 are again composed of partial struts 3a and 4a, joinable with each other in the manner of plug connections.

[0038] As in the embodiment example according to FIGS. 1 through 5, in assembly position the front support struts 3 are shorter than the rear support struts 4. The seat surface 5a and back 5b are formed this way in connection with the installed covering 5. When collapsing the support struts 3, 4, their partial supports 3a and 4a are held to each other via rope-type and, for example, elastic connections in an undetachable way and in a manner not further illustrated.

[0039] In the variant according to FIGS. 6 and 7, the leg 2 is formed by two pairs of foot elements 2c, each with two foot elements 2a, and a cross brace 21 that extends when in assembly position between the two pairs of foot elements 2c. The joint of the cross brace 21 with the pairs of foot elements 2c is implemented using as central holding element 2b formed accordingly from two partial elements 2d, wherein the partial elements 2d are swivelably connected with the foot elements 2a of the respective pair of foot elements 2c, again via joint connections 13. The joint of the cross brace 21 with the partial elements 2d of the central holding element 2b is again advisably embodied as a plug connection. To this end, corresponding plug openings 22 are provided for in the partial elements 2d, which each receive one of the strut ends of the cross brace 21 when in assembly position.

[0040] The invention is not limited to the embodiment examples described above. Instead, other variants of the invention can also be derived by the person skilled in the art, without abandoning the object of the invention. In particular, all individual elements described in conjunction with the embodiment examples are combinable in the future without abandoning the object of the invention.

[0041] Thus, for example, the leg 2 embodied in FIGS. 1 through 5 as a tripod can also be formed as a quadrupod, accordingly with four foot elements 2a. In addition, the plug openings 19 of the leg 2 can also be positioned at other locations. Thus, these plug openings 19 for the support struts 3, 4similar to the embodiment example according to FIGS. 6 and 7can also be provided with a central bolding element 2b, accordingly designed. The rope-type connection element 8 that is provided for, if needed can also be made of multiple parts and, for example, connected in a cross connection with the foot elements 2a in their middle area or joint-end area, on the one hand, and in the free-end foot area, on the other.

[0042] In addition, the support struts 3, 4 can be embodied at the same length, and the covering 5 can be provided as a flat covering element. In this way, instead of the chair shown, a stool, i.e. a backless chair, or a table can be assembled as a mobile piece of furniture 1 whose seat or table surface is formed from the covering element. With regard to this, only an accordingly modified covering must be provided, and with the comparatively long support struts 4 only a partial strut 4a must be omitted, so that both a table and a chair are assemblable and the individual parts jointly packable in leg 2 with the represented and described parts.

[0043] While the leg 2 as a functional part takes on the additional packing function in the described embodiment examples, this can be taken on by the covering 5 as well. To this end, this can be provided with a zipper or Velcro closure in order to close accordingly the covering 5 receiving the remaining parts for the purpose of transportation and storage.
