The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
- The invention generally provides a foldable chair and in some embodiments a foldable table configured to either use the chair as a leg when the chair is in its deployed position or to store up to four foldable chairs in their retracted position. In certain embodiments of the foldable chair, each foldable chair includes a seat portion and a telescopic side wall extending downwardly from the seat portion. The telescopic side wall may be configured with a deployed position and a retracted position. In the deployed position the telescopic side wall may be configured to be completely opened such or partially folded such that the desired height of the chair can be set. The side wall may include a plurality of rings each having varying diameters and consecutively arranged such that the topmost rings, which is mounted to the bottom surface of the seat portion, has the smallest diameter while the bottom most member has the largest diameter. In this way, in the retracted position the rings can be consecutively disposed inside one another. For example in the fully retracted position all the rings are disposed adjacent the bottom surface of the chair portion. In some embodiments, the rings are provided with a locking arrangement configured to selectively lock each ring with respect to adjacent rings. This way, in the deployed position the rings are locked with respect to one another thus consecutively extending, while in the retracted position the rings are unlocked, thus can be folded towards the bottom surface of the seat portion of the chair.
- According to a non-limiting example, the locking arrangement includes at least one pin provided on each of the rings and a corresponding groove on an adjacent ring. The groove extends along the height of the ring and includes an arched segment. The pin is configured to slide along the groove and in and out of the arched segment. When the pin is disposed in the arched segments the pin locks the two adjacent rings to one another, rotation of the ring sidewardly with respect to the adjacent ring causes the pin to slide out of the arched segment and unlocks the ring. Further sliding the pin along the groove causes the ring to fold. Each pin can be provided with a top portion configured for snap-coupling, such that the pin is maintained in the arched segment.
- In some embodiments, the chair is provided with an actuating mechanism for rotating the rings with respect to one another. For example, the actuating mechanism can include a rotation disk on the bottom surface of the seat portion coupled to the topmost ring. Rotation of the rotation disk causes the rotation of the ring and allows locking or unlocking thereof.
- According to one example, each of the rings is an integral unit. In one non-limiting implementation of the ring, the integral unit of the ring has integrally connected segments, wherein each segment may be provided with a groove for coupling to a corresponding pin of an adjacent ring.
- The invention further provides a folding table having a foldable table portion with one of the foldable chairs mounted thereto as a leg for the table. The table portion includes two segments configured to be folded one on the other using hinges such that a delimited area is formed therebetween. The delimited area is configured with a pair of pins to accommodate a foldable chair in a retracted position of the foldable chair and to hold up to four such chairs in stored position.
- The folding table can further include a locking arrangement for locking the leg of the table—which is the foldable chair in retracted position—to the table portion and to hold the stored chair(s) to the table portion in a stored position.
- The principles and operation of a foldable chair may be better understood with reference to the drawings and the accompanying description.
- As seen from
FIGS. 1-11D , in one embodiment, the invention is afoldable chair 10, comprising aseat portion 20 and atelescopic side wall 30 extending downwardly fromseat portion 20.Telescopic side wall 30 includes a plurality ofrings 40 of varying diameters that may be consecutively arranged such that atopmost ring 41 is mounted to abottom surface 22 ofseat portion 20 and has a smallest diameter and abottommost ring 49 has a largest diameter. In one non-limited option,seat portion 20 can be cushioned or padded. -
Telescopic side wall 30 is configured to have a deployed position (seeFIG. 1 andFIG. 10 ) that is completely opened or partially folded such that a desired height of thechair 10 is set and locked, and a retracted position (seeFIG. 9 ) such that in a fully retracted position all of therings 40 are disposed adjacent the bottom surface of theseat portion 20, wherein each of therings 40 is an integral unit configured with a locking arrangement 50 that selectively locks eachring 40 with respect to anadjacent ring 40. - As seen from
FIG. 1 , typically,seat portion 20 has a larger diameter than the diameter of thetopmost ring 41 in order to accommodate a person in seated position. -
Chair 10 may also comprise a security lock 60 centrally disposed along a height, H, of thefoldable chair 10 substantially perpendicular to the varying diameters of therings 40, the security lock 60 configured to secure the locking arrangement 50. - In some embodiments, the security lock 60 comprises a
flexible cable 62 centrally disposed within a spring 63 through the height of (in some embodiments substantially throughout the height of) thefoldable chair 10 and connecting theseat portion 20 with thebottommost ring 49 in both the deployed and retracted positions, thebottommost ring 49 having an actuator 64 accessible to a user, wherein a coupler 66 couples theactuator 64 to thecable 62 so that a user who actuates theactuator 64 releases the security lock 60 by releasing pressure on theflexible cable 62. The height ofchair 10 refers to the direction running from theseat portion 20 to thebottommost ring 49 substantially perpendicular to the diameters ofrings 40. In certain embodiments, a top portion ofcable 62 is connected to seatportion 20. In certain embodiments,cable 62 is a loop, in some cases a closed loop. In one embodiment,cable 62 is elastic in the sense that it returns to its original shape after forces on it are removed. -
FIGS. 11B-11C show one embodiment in which actuator 64 utilizes a coupler 66 to indent a central portion ofcable 62 to increase pressure oncable 62 to activate security lock 60. Reverse rotation unlocks security lock 60. -
FIG. 11D shows another embodiment in which actuator 64 is connected to a lower end ofcable 62 and rotation ofactuator 64twists cable 62 which shortens it and creates pressure on it to makecable 62 more rigid thereby activating security lock 60. Reverse rotation unlocks security lock 60. - It should be noted that security lock 60 is also a stabilizer that stabilizes the
chair 10 in its fully retracted or partially retracted (partially deployed) position and prevents it from buckling or wobbling or collapsing. -
FIG. 11A showscable 62 whenchair 10 is in a retracted position so thatcable 62 fits inseat portion 20 ofchair 10. - In the deployed position (
FIG. 1 ,FIG. 10 ), rings 40 are locked with respect to one another thus consecutively extending a height of thefoldable chair 10, while in the retracted position (FIG. 9 ) therings 40 are unlocked and foldable towards a bottom surface of theseat portion 20. - In one embodiment, the locking arrangement 50 includes, for each
ring 40 exceptuppermost ring 41, a pin 52 (seeFIGS. 7A, 7B, 7C and 7D ) and agroove 54 on each of therings 40 such that thepin 52 fits with a correspondinggroove 54 on anadjacent ring 40. This is true except foruppermost ring 41 which only haspins 52 but nogrooves 54 since it is only adjacent thering 40 below it. In some embodiments, as best seen inFIG. 8B andFIG. 8C ,groove 54 extends along a height of thering 40 and includes anarched segment 54A wherein thepin 52 of theadjacent ring 40 is configured to slide along thegroove 54 and in and out of thearched segment 54A. - In some embodiments, as seen from
FIG. 7A ,FIG. 7B ,FIG. 7C andFIG. 7D , thetopmost ring 41 includes thepin 52 but no slot/groove 54. - The
pin 52 may be disposed in thearched segments 54A such that thepin 52 locks twoadjacent rings 40 to one another, and rotation of afirst ring 40 sidewardly with respect to an adjacent ring causes thepin 52 to slide out of thearched segment 54A and unlocks thefirst ring 40 and wherein further sliding of thepin 52 along thegroove 54 causes thefirst ring 40 to fold. - As seen in
FIG. 9 andFIG. 10 , locking arrangement 50 may include anactuating mechanism 59 for rotating therings 40 with respect to one another and thereby releasing the locking arrangement 50. In one non-limiting example, theactuating mechanism 59 comprises or includes arotation disk 59 on a top surface of theseat portion 20 coupled to atopmost ring 41 such that a pulling and rotation motion of therotation disk 59 rotates therings 40 to release the locking arrangement. As shown inFIG. 59 ,chair 10 may also include an integrated carryingstrap 99. - In another embodiment of the invention shown in
FIG. 12A ,FIG. 12B ,FIG. 13 ,FIG. 14 ,FIG. 16 andFIG. 17 , the invention is a foldable table 100 having a deployed table position and having a table storage position. Foldable table 100 comprises (A) aleg portion 10 comprising afoldable chair 10 either positioned centrally as a leg of the foldable table 100 or positioned peripherally for storage on an underside of the table portion of the foldable table. - Each
