Abstract
Adjustable furniture having a seat and a back and a support component. Two mutually parallel elongate support members on said support component are each passing through a corresponding support sleeve and a downwardly extending slotted opening at the rear side portion of the seat. Said support members extend obliquely upwards at an angle with the horizontal plane of about 30.degree.. A rubber block located at the upper side portion of said slotted opening is providing a friction promoting support of said seat against the associated support member and simultaneously a resilient yielding spring effect between said seat and said support member.
Claims8
An article of furniture of an adjustable kind, such as a chair, especially a child's chair, as well as a stool and similar furniture, comprising a support component provided with a pair of backward inclining elongate tubular members for supporting a seat in adjustable positions thereat, whereas at the rear portion of said seat said tubular members are passing through a pair of support sleeves and a pair of slotted openings diverging downwards from said support sleeves, which slotted openings are allowing the seat to be tilted about a horizontal axis at the rear side portion of the seat by lifting the front side portion thereof, characterized in
- that the support sleeves are made of a slide promoting material, such as plastic material, for allowing the seat to be slided freely along said tubular members with a minimum of friction, in an upwardly tilted position of the seat, and
- that the upper side portion of said slotted openings spaced from said support sleeves is provided with a block of elastically yielding, friction promoting material, such as rubber, and said block is providing a main support surface between said seat and its associated tubular support member and of sufficient thickness to provide a spring effect between said seat and its associated tubular member, in a normal downwardly tilted position of the seat.
A chair comprising
- a support component including a pair of U-shaped tubular members, one of said members having a pair of leg portions extending at an oblique angle to a horizontal plane;
- a back secured to the other of said members;
- and
- a seat slidably mounted on said leg portions of said one tubular member, said seat including a pair of support sleeves and a pair of elastically resilient blocks, each said sleeve having a respective leg portion extending therethrough and including a slotted cavity facing said leg portion and each said block being received in a respective cavity in contact with a respective leg portion with a thickness sufficient to provide a spring effect between said seat and said respective leg portion.
