The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
At first consult shown in Figure 1ly, secondary linkage leg support mechanism 1 of the present utility model mainly comprises an erection support assembly 10, a leg holder assembly 11, a connecting rod mechanism 12 and a driver train 13.Leg holder assembly 11 and connecting rod mechanism 12 are installed on respectively on the erection support assembly 10, and driver train 13 connects connecting rod mechanism 12 and drives connection leg holder assembly 11 by connecting rod mechanism 12, wherein:
Cooperate shown in Figure 2ly, erection support assembly 10 comprises a mounting rod 100 and is connected to two erection supports 101 of mounting rod 100 both sides.
Connecting rod mechanism 12 comprises two groups of connecting rod assemblies, two groups of connecting rod assemblies are installed on respectively on two erection supports 101, connecting rod assembly further comprises one first drive spindle 121, one second drive spindle 122 and a follower lever 120, the first end 1211 of the first drive spindle 121 is articulated in the second end 1012 of erection support 101, the second end 1212 of the first drive spindle 121 articulates the second end 1222 of the second drive spindle 122, the first end 1221 of the second drive spindle 122 is articulated in secondary leg holder 112, the first end 1201 of follower lever 120 articulates the first end 1011 of erection support 101, the second end 1202 of follower lever 120 is articulated in the middle part of the second drive spindle 122, wherein, erection support 101, the first drive spindle 121, the second drive spindle 122 and follower lever 120 consist of a four-bar linkage, during the first drive spindle 121 stressed travelling forward, promoting above-mentioned four-bar linkage swings forward, so that the second drive spindle 122 forward translation promote the holder 111 of one-level leg and upwards rotate around drive-connecting shaft 16, simultaneously, the second drive spindle 122 forward translation promotes the slide block 110 of secondary leg holder 112 with respect to chute 113 slips of one-level leg holder 111 both sides, finally increases the effect that leg support of seat uses length to reach.The middle part of two the first drive spindles 121 connects respectively the two ends of a cross bar 17, and the middle part of cross bar 17 is provided with a pivot connecting seat 15, articulates driver train 13 on pivot connecting seat 15, and driver train 13 drives cross bar 17 and moves forward.
When concrete use the utility model mechanical type secondary linkage leg support mechanism, open driver train 13, promoting the first drive spindle 121 rotates forward, the second drive spindle 122 is done rotation upwards and translation forward under the first drive spindle 121 and follower lever 120 combineds action, thereby, promoting one-level leg holder body rotates around drive-connecting shaft 16, simultaneously, slide between secondary leg holder 112 and the one-level leg holder 111, that is: slide block 110 stretches out forward secondary leg holder 112 in chute 113 slides forwards of one-level leg holder 111.
The utility model can be on the other hand moving electrodeless adjusting mechanical type secondary linkage leg support mechanism, energy-conserving and environment-protective, at this moment driver train 13 can be an air bellow, release air bellow release lever, air bellow extends under self elastic force effect, after leg support mechanism 1 is adjusted to the right place, discharges the air bellow release lever, air bellow is locking at an arbitrary position, thereby the bearing force of leg holder is provided.Simultaneously, consider that seat system is arranged and the transmission of four-bar linkage power, air bellow is controlled at the placement angle of initial position and horizontal surface ± 15 ° scope in.
