Specific implementation mode
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described：
See Fig. 1, Fig. 2, Fig. 3, a kind of leisure footrest rack for seat, including seat connecting rod 1, it is connected to seat connection
It fixed link 2 on bar 1, the leg rest pedestal 3 being connected in fixed link 2, the limiting lock 4 being fixedly connected in fixed link 2 and is set to
Limit actuating mechanism 5 on leg rest pedestal 3, seat connecting rod 1 can be connected to seat bottom, can make chair by the way that connecting sliding rail is arranged
Seat connecting rod 1 is movable；The both sides of leg rest pedestal 3 are equipped with the fold side bumper 31 being rotatablely connected with fixed link 2, turn down and are set on side bumper 31
There is the guide groove 32 moved for limit actuating mechanism 5；Leg rest pedestal 3 have storage station between the seat connecting rod 1 and
With the station that uses of the flattening of extending 1 one end of seat connecting rod, storage station collapses the seat in chair when usually leaving unused
Under bottom, leg rest pedestal 3 is stretched out in except the seat bottom of chair using when station, that is, leg rest；Limiting lock 4, which is equipped with, is located at side
The first locking notch 41 and the second locking notch 42 positioned at the other side；Guide groove 32 and limit actuating mechanism 5 cooperation first
Locking notch 41 makes leg rest pedestal 3 be in storage station such as Fig. 1, and guide groove 32 and limit actuating mechanism 5 coordinate the second locking to lack
Mouth 42 makes leg rest pedestal 3 use station such as Fig. 2 in flattening.Leg rest pedestal 3 includes component installation front 33 and the component installation back of the body
Face 34, fold side bumper 31 turn down vertically towards component installation 34 direction of the back side, and limit actuating mechanism 5 is set to component and installs the back side 34.
Limit actuating mechanism 5 include both ends merging guide groove 32 in gag lever post 51, at least one on leg rest pedestal 3
To replacement and fixation piece 52 and it is fixedly connected on gag lever post 51 and passes through the pull rod 53 of replacement and fixation piece 52.Limit actuating mechanism 5 also
Including the resetting spring 54 being placed on pull rod 53 and between replacement and fixation piece 52, one end of pull rod 53, which is equipped with, supports patch reset
The blocking portion 511 of spring 54, blocking portion 511 is used for the pressed home spring 54 after the pulling of pull rod 53, then is stretched by resetting spring 54
Open up return.Pull rod 53 is also associated with pull handle 55.51 position of gag lever post is adjusted by pulling pull rod 53, then drives entire leg rest
Frame 3 circumferentially rotates.Limiting lock 4 can be sheet shaped piece, itself be weldingly fixed in fixed link 2.It is additionally provided with and is located on limiting lock 4
Between first locking notch 41 and the second locking notch 42 is one of rotation cambered surface of shaft 43 and rotation cambered surface with fixed link 2
2 44；It rotates one of cambered surface 43 and rotates the 2 44 of cambered surface and be more than guide groove 32 relative to solid relative to the radius of fixed link 2
The minimum rotation radius of fixed pole 2 and be less than maximum rotating radius of the guide groove 32 relative to fixed link 2, in this way design allow for limiting
Position bar 51 can be stuck in the first locking notch 41 or the second locking notch 42, and can be by pulling pull rod 53 so that limit
Bar 51 can be detached from the first locking notch 41 or the second locking notch 42 again and along one of rotation cambered surface 43 or rotate the two of cambered surface
44 freely circumferentially rotate.First locking notch 41 is equipped with for coordinating limit actuating mechanism 5 to prevent leg rest pedestal 3 from rotating
First level blocking portion 411 and the first vertical blocking portion 412, the second locking notch 42 are equipped with for coordinating limit actuating mechanism 5
The the second horizontal blocking portion 421 and the second vertical blocking portion 422, these blocking portions for preventing the rotation of leg rest pedestal 3 are all for hindering
Gag lever post 51 is kept off, to control the rotation of footrest rack 3.First level blocking portion 411 and the second horizontal blocking portion 421 are equipped with anti-
Slip concave surface；First level blocking portion 411 and the second horizontal blocking portion 421 are equipped with anti-slip blocking end.These are anti-slip
Design prevent entire footrest rack 3 from influencing to use since external force undesirably falls off stationary state, convenient for by manpower realize manually
Controllably.
