Description

DESCRIPTION
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a leisure chair with a footrest unit and, more particularly, to a leisure chair including a footrest unit that has a reduced volume in a store position, has a larger span in an extended position, and provides more stable operation.
[0002] A type of conventional chairs includes a footrest for supporting the calves of a user to increase the sitting comfort, and the footrest can be moved between an extended position and a storage position to provide convenience use to the user.
[0003] A conventional footrest is generally mounted below a front end of a seat of a chair and is generally perpendicular to the seat in the storage position. The footrest can be pivoted to a position substantially parallel to the seat. An example of such a footrest is disclosed in U.S. Patent Nos. 6,572,185; 7,134,713; and 6,402,232. However, the footrest is limited by the height of the seat from the ground, leading to insufficient extended length of the footrest.
[0004] In an arrangement, the footrest can be extended when a backrest of the chair is moved. However, the footrest cannot be moved to the extended position when the backrest is not moved to in a rearward inclination position. In another arrangement, movement between the extended position and the storage position of the footrest can be achieved by a control rod that cannot be operated conveniently while increasing the costs.
BRIEF SUMMARY OF THE INVENTION
[0005] An objective of the present invention is to provide leisure chair including a footrest unit that has a reduced volume in a store position, has a larger span in an extended position, and provides more stable operation.
[0006] A leisure chair with a footrest unit according to the present invention includes a base adapted to be placed on a ground. The base includes a horizontal rod having two ends spaced from each other in a width direction. The horizontal rod includes a front supporting portion extending forwards from the horizontal rod and located between the two ends of the horizontal rod. An armrest is adapted to be mounted to each of the two ends of the horizontal rod. A seat is mounted on top of the base and includes a front side and a rear side. The seat includes two lateral rods spaced from each other in the width direction and a front rod extending between the two lateral rods. The seat is movable relative to the base in a forward/rearward direction perpendicular to the width direction between a front position and a rear position. A backrest is connected to the rear side of the seat. A footrest unit is movable between a storage position and an extended position spaced from the storage position in the forward/rearward direction.
The footrest unit includes at least one first link, at least one second link, a first pivotal frame, a third link, a second pivotal frame, at least one fourth link, and at least one connection frame. Each of the at least one first link and the at least one second link is pivotably connected to a front end of the front supporting portion. A front side of the first pivotal frame in the storage position is pivotably connected to the at least one first link, the at least one second link, and the front side of the seat. A front end of the third link in the storage position is pivotably connected to the front side of the seat. A rear side of the second pivotal frame in the storage position is pivotably connected to a rear side of the first pivotal frame and a rear end of the third link. A rear end of the at least one fourth link in the storage position is pivotably connected to the rear side of the fist pivotal frame. A front side of the at least one connection frame in the storage position is pivotably connected to a front side of the second pivotal frame. A rear side of the at least one connection frame in the storage position is pivotably connected to a front end of the at least one fourth link.
[0007] Forward movement of the seat causes the at least one first link and the at least one second link to pivot and causes the footrest unit to fold and move to the storage position below the seat. The at least one first link and the at least one second link form a folded part of the footrest unit.
[0008] Rearward movement of the seat causes the at least one first link and the at least one second link to pivot and extend and causes the footrest to extend and move to the extended position in front of the seat.

Each twenty-seventh pivotal portion 472 is pivotably connected to the twenty-fifth pivotal portion 462 of one of the two fourth links 46. A soft pad (not shown) can be mounted on top of the connection frames 47.
[0028] When the footrest unit 4 is not extended, the footrest unit 4 is pulled and positioned by the elastic elements 27 of the seat 2. When the footrest unit 4 is folded, the first links 41 and the second links 42 are pivoted and, thus form a folded part of the footrest 4 relative to the base 1. Thus, the footrest unit 4 can be received in the receiving space 151 and between the two front posts 15. Furthermore, the second pivotal frame 45 is received between the two first lateral beams 431 of the first pivotal frame 43. As a result, the footrest unit 4 can be folded and stored. The overall thickness A (FIG. 3) of the footrest unit 4 in the storage position is reduced, providing a sense of quality. Furthermore, when a user sits in the seat 2, the front side of the seat 2 presses against the front posts 15 of the supporting portion 14, and the two pivotal columns 17 are substantially perpendicular to the ground to provide a stable supporting effect. At this time, the control device 35 can be operated to control the telescopic rod 34 for adjusting the rearward inclination angle of the backrest 3 (not shown).
[0029] With reference to FIGS. 4-6, when the user holds the armrests 13 and moves his or her buttocks rearwards to apply a force moving the seat 2 rearwards relative to the base, the footrest unit 4 is extended and moves from the storage position to the extended position. During the movement of the footrest unit 4, the upper ends of the pivotal columns 17 move rearward, abut against the stop portions 163 of the base 1, and are stopped and positioned by the stop portions 163 while stretching the elastic elements 27. During the rearward movement of the seat 2, the first and second links 41 and 42 pivot about the front supporting portion 14 of the base 1 to cause forward extension of the first pivotal frame 43 while causing upward extension of the second pivotal frame 45, the second links 46, and the connection frames 47. The whole span B of the footrest unit 4 in the extended position shown in FIG. 5 is larger than the length of the first pivotal frame 43 to provide better supporting comfort for the calves of the user. In this case, the user can also use the control device 35 to control the length of the telescopic rod 34 and the rearward inclination angle of the backrest 3, as shown in FIG. 6.
[0030] When it is desired to fold the footrest unit 4 again, the use can use the legs to apply a downward force to fold the footrest 4 and to move the seat 2 forward to a state shown in FIG. 3. The returning force of the elastic elements 27 provides easy, convenient folding. Operation of the footrest unit 4 does not require any other control rod.
[0031] In view of the foregoing, the footrest unit 4 of the leisure chair in the storage position has a reduced volume to provide a sense of quality. Furthermore, the footrest unit 4 of the leisure chair in the extended position has a larger span to provide increased supporting comfort for the legs of the user. Furthermore, the operation is more stable. Furthermore, the footrest unit 4 is not operatively connected to the backrest 3, such that the leisure chair does not have to include the telescopic rod 34 if adjustment of the inclination angle of the backrest 3 is not required.
[0032] Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
