Abstract

An adjustable deck-chair comprises a frame having two lateral frame portions interconnected by a cross-bar. A seat-back assembly is pivotably supported by the lateral portions of the frame and is movable between an upright position in which the back is substantially perpendicular to the seat and a reclined position in which the seat and the back enclose an angle approximating 180°. The seat-back assembly is arrested in the upright position by a force exerted on the seat by a friction and detent member which is pivotably supported on the cross-bar and frictionally and wedgingly engages a portion of the seat frame. The lateral portions of the frame may be collapsible.

Claims

1. An adjustable deck-chair, comprising a frame having an elongated cross-bar;

a seat-back assembly including a back pivoted on said frame and a seat pivotably connected to said back; and

supporting means for supporting said seat on said cross-bar for movement between a forward and a retracted position, said supporting means including a friction and detent member pivotably mounted on said cross-bar for angular displacement about the same and having a passage extending transversely of the elongation of said cross-bar and offset therefrom, and a bracket connected to said seat underneath the same and slidably received in said passage in frictional contact with the surface bounding said passage for arresting of said seat in and intermediate said positions thereof.

2. A deck-chair as defined in claim 1, wherein said back is pivoted on said frame for movement between an upright orientation assumed when said seat is in said retracted position, and a substantially horizontal orientation assumed when said seat is in said forward position.

3. A deck-chair as defined in claim 1, wherein said seat has a rear end pivotably connected to said back, said bracket extending in the front-rear direction of said seat;

and wherein said bracket is provided in the region of its forward end with a tongue emerging out of the bracket so as to form a wedge therewith, and received in said passage when said seat is in its retracted position to arrest said seat in such position.

4. A deck-chair as defined in claim 1, wherein said frame includes a pair of lateral portions interconnected by said cross-bar;

and wherein each of said lateral portions includes a plurality of interconnected sections.

5. A deck-chair as defined in claim 1, wherein said friction and detent member is of elastic material.

6. A deck-chair as defined in claim 1, wherein said seat has a rear end pivotably connected to said back;

and wherein said bracket encloses with said seat an acute angle diverging in the rearward direction thereof.

7. A deck-chair as defined in claim 3, wherein said wedge formed by said bracket and said tongue diverges in the forward direction of said bracket.

8. A deck-chair as defined in claim 1, further comprising a leaf spring attached to said friction and detent member and having a substantially semi-annular free end portion emerging out of said friction and detent member;

and wherein said bracket is provided with a recess adapted to accept said free end portion of said leaf spring when said seat is in its retracted position.

9. A deck-chair as defined in claim 1, wherein said bracket is provided with an enlarged portion which at least partially enters said passage when said seat approaches said retracted position thereof.

10. A deck-chair as defined in claim 9, wherein said enlarged portion is a spring attached to said bracket.

11. A deck-chair as defined in claim 9, wherein said bracket is provided with a recess adapted to accept a biconvex resiliently yieldable element forming said enlarged portion of said bracket.

12. A deck-chair as defined in claim 9, wherein said enlarged portion is formed by a flat convex element of resiliently yieldable material attached to said bracket. retracted

13. A deck-chair as defined in claim 1, said friction and detent member having an upper side provided with a recess;

and further comprising a ball-shaped pin biased in the downward direction of said seat and adapted to be accepted in said recess when said seat is in said reatracted position thereof.

14. A deck-chair as defined in claim 1, further comprising a retaining member attached to said seat and having a projection extending downwardly and moving in a path as said seat moves between said positions thereof;

and wherein said friction and detent member has an upwardly directed side provided with a rib extending into said path.

15. A deck-chair as defined in claim 1, wherein said bracket has a forward end portion extending parallel to said seat at a predetermined distance;

and wherein said friction and detent member is a roller having a diameter larger than said predetermined distance and accepted between said forward end portion and said seat when said seat is in its retracted position.

16. A deck-chair as defined in claim 15, said bracket having a wave-shaped configuration.

17. A deck-chair as defined in claim 4, wherein each of said lateral portions includes an arm-rest section and two pivotably interconnected support sections, said arm-rest section being pivotably attached to one of said support sections and dismountably connected to the other support section.

18. A deck-chair as defined in claim 17, said arm-rest section having a first free end and said other support section having a second free end, each of said free ends being provided with a cylindrical cavity and having end faces adapted to bluntly abut one another;

and further comprising a spreading device inserted into said cylindrical cavities and comprising two spreadable portions frictionally engaging the surfaces bounding said cavities and preventing mutual displacement of said free ends upon spreading of said portions of said spreading device.

19. An adjustable deck-chair, comprising a seat-back assembly including a seat and a back pivotably connected to one another;

a frame including a first and a second support section, two arm-rest sections and a cross-bar connecting two laterally spaced portions of said first support section;

a pivot pivotably connecting said back to said second support section and said arm-rest sections to said second support section, said back and said arm-rest sections being movable independently of one another;

adjusting means connecting said seat to said cross-bar with freedom of movement in a limited range; and

a spreading device connecting the respective one of said arm rest sections to the associated lateral portion of said first support section.
