Detailed description of the invention
Below in conjunction with accompanying 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, the fixing bar 2 including seat support connecting rod 1, being connected in seat support connecting rod 1, the leg rest pedestal 3, the limiting lock 4 being fixedly connected on fixing bar 2 and the spacing actuating mechanism 5 being located on leg rest pedestal 3 that are connected on fixing bar 2, seat support connecting rod 1 is connectable at the bottom of seat support, seat support connecting rod 1 can be made movable by arranging connecting sliding rail；The both sides of leg rest pedestal 3 are provided with and fix the turnover side bumper 31 that bar 2 is rotationally connected, and turnover side bumper 31 is provided with the gathering sill 32 moved for spacing actuating mechanism 5；Leg rest pedestal 3 has the storage station and the use station with the flattening extending seat support connecting rod 1 one end being between seat support connecting rod 1, storage station draws in when leaving unused the most at ordinary times and is under the seat bottom of chair, is stretched out in by leg rest pedestal 3 outside the seat bottom of chair during use station i.e. leg rest；Limiting lock 4 is provided with the first locking breach 41 being positioned at side and the second locking breach 42 being positioned at opposite side；Gathering sill 32 and spacing actuating mechanism 5 coordinate the first locking breach 41 to make leg rest pedestal 3 be in storage station such as Fig. 1, and gathering sill 32 and spacing actuating mechanism 5 coordinate the second locking breach 42 to make leg rest pedestal 3 be in flattening use station such as Fig. 2.Leg rest pedestal 3 includes that front 33 installed by assembly and the back side 34 installed by assembly, and turnover side bumper 31 is installed direction, the back side 34 towards assembly and vertically turned down, and spacing actuating mechanism 5 is located at assembly and is installed the back side 34.
Spacing actuating mechanism 5 includes the gag lever post 51 inserting in gathering sill 32 in two ends, be located on leg rest pedestal 3 at least one pair of replacement and fixation sheet 52 and be fixedly connected on gag lever post 51 and the pull bar 53 through replacement and fixation sheet 52.Limit the back-moving spring 54 that actuating mechanism 5 also includes being placed on pull bar 53 and between replacement and fixation sheet 52, one end of gag lever post 51 is provided with the stop part 511 to patch back-moving spring 54, stop part 511 is for pressed home spring 54 after gag lever post 51 pulls, then is stretched return by back-moving spring 54.Pull bar 53 is also associated with pull handle 55.By pulling pull bar 53 to regulate gag lever post 51 position, then drive circumferentially rotating of whole footrest rack 3.Limiting lock 4 can be sheet shaped piece, itself is weldingly fixed on fixing bar 2.One of rotation cambered surface with fixing bar 2 as rotating shaft being additionally provided with on limiting lock 4 between the first locking breach 41 and the second locking breach 42 43 and rotate the 2 44 of cambered surface；Rotate one of cambered surface 43 and rotate the 2 44 of cambered surface relative to the radius of fixing bar 2 more than gathering sill 32 relative to the minimum rotation radius of fixing bar 2 less than gathering sill 32 relative to the maximum rotating radius of fixing bar 2, so design allows for gag lever post 51 and can be stuck in the first locking breach 41 or the second locking breach 42, and can by pull pull bar 53 to make gag lever post 51 can depart from again the first locking breach 41 or the second locking breach 42 and along rotating one of cambered surface 43 or rotating the 2 44 of cambered surface and carry out freely circumferentially rotating.First locking breach 41 is provided with the first horizontal stop part 411 and the first vertical stop part 412 for coordinating spacing actuating mechanism 5 to prevent leg rest pedestal 3 from rotating, second locking breach 42 is provided with the second horizontal stop part 421 and the second vertical stop part 422 for coordinating spacing actuating mechanism 5 to prevent leg rest pedestal 3 from rotating, these stop parts are all used to stop gag lever post 51, thus control the rotation of footrest rack 3.First horizontal stop part 411 and the second horizontal stop part 421 are provided with anti-slip concave surface；First horizontal stop part 411 and the second horizontal stop part 421 are provided with anti-slip stop end.These anti-slip designs prevent whole footrest rack 3 from affecting use owing to external force undesirably falls off stationary state, it is simple to realize human controllable by manpower.
