[specific embodiment]
See also the Seat foot frame folding structure embodiment shown in Fig. 1,2,3, the facility that it provides the user to launch to take and fold storage is particularly useful for using in the middle of the bathroom; The utility model comprises a support body 1, one preceding support foot rest 2, a back support foot rest 3 and an a pair of restriction frame 4.
Wherein support body 1 comprises that one supplies the people to take the seat board 11 and a underframe 12 of usefulness, wherein is provided with Connection Block 13 in underframe 12 both sides.Described Connection Block 13 is provided with restriction elongated slot 131, and the bottom surface of underframe 12 is provided with pin joint seat 14.
Preceding support foot rest 2 slightly is ㄇ font and the rotatable means pin joint seat 14 in these underframe 12 1 sides.In the middle of the present embodiment, preceding support foot rest 2 comprises a upper bracket 21 and a pair of lower carriage 22; Wherein these can be with respect to the flexible length of adjusting of upper bracket 21 to lower carriage 22, adjusting the height of seat, and at these lower carriage 22 bottom devices sliding-proof pad 23 are arranged, and the stability when taking to increase seat is avoided sliding.Upper bracket 21 is provided with a fixing pole 24, make its current support foot rest 2 devices when the Connection Block 13 of underframe 12, just in time be positioned at restriction elongated slot 131, and support foot rest 2 rotates (be smooth in underframe 12 and summary in the scope perpendicular to this support body 1) before can limiting in the scope angle of this restriction elongated slot 131.Before the upper bracket 21 of support foot rest 2 be fixedly connected or extend have a pair of can be with the positioning seat 25 of preceding support foot rest 2 rotations.
Back support foot rest 3 slightly is the ㄇ font and also installs rotationally on the Connection Block 13 of these underframe 12 opposite sides.In the middle of the present embodiment, back support foot rest 3 comprises a upper bracket 31 and a pair of lower carriage 32.This can stretch with respect to upper bracket 31 to lower carriage 32 and adjust length, and in these lower carriage 32 bottom device sliding-proof pads 33.Upper bracket 31 is provided with a fixing pole 34, when the Connection Block 13 of back support foot rest 3 device at underframe 12, upper bracket 31 is sitting in the restriction elongated slot 131, in the angular range of restriction elongated slot 131, rotates (being smooth in underframe 12 and scope slightly) to limit back support foot rest 3 perpendicular to this support body 1; And it is fixedly connected or extend the positioning seat 35 that a pair of 3 rotations of support foot rest are subsequently arranged at the upper bracket 31 of this back support foot rest 3.In the middle of present embodiment, the width of back support foot rest 3 makes it after folding greater than preceding support foot rest 2, all can be smooth with preceding support foot rest 2 in the bottom surface of support body 1, and make back and front supporting foot rest 2,3 after folding, be positioned at same plane.
A pair of restriction frame 4, it is articulated on the pin joint seat 14 of this underframe 12, be located between the back and front supporting foot rest 2,3, this is equipped with restriction seat 5 to restriction frame 4 two ends in the middle of present embodiment, this restriction seat 5 is articulated on the pin joint seat 14 of this underframe 11 with an articulated section 51, make this restriction seat 5 rotating formation one standing states and rotation be lying status, this restriction seat 5 further comprises and pushes up pull an end face 52 and an accommodation space 53.
Please continue with reference to shown in the figure 4-6, when forward and backward support foot rest 2,3 during in deployed condition, restriction seat 5 forms a standing state (as shown in Figure 3) through rotation; At this moment, the pull positioning seat 25,35 of end face 52 ejection back and front supporting foot rests 2,3 of the top of restriction seat 5 makes back and front supporting foot rest 2,3 keep the deployed condition vertical with support body 1.When the operator desires folding back and front supporting foot rest 2,3, can operate this restriction frame 4 is rotated, make restriction seat 5 be lying status; At this moment, this accommodation space 53 is positioned on the rotation track of positioning seat 25,35 on this back and front supporting foot rest 2,3 just, and makes rotatable the folding of back and front supporting foot rest 2,3 and smooth in support body 1 bottom surface.At this moment, the positioning seat 25,35 of back and front supporting foot rest 2,3 is positioned at the accommodation space 53 central (as shown in Figure 6) of this restriction seat 5.
In the middle of present embodiment, the flexible assembly 6 of device between restriction seat 5 and pin joint seat 14.Elastic parts 6 can be a torque spring, utilize its elasticity that torsion is provided, under the normal condition of no external force, keep this restriction seat 5 to be standing state, pulled and be deployed condition in back and front supporting foot rest 2,3 tops keeping, increase the stability of back and front supporting foot rest 2,3, and avoid being folded back and front supporting foot rest 2,3 by accident.When device elastic parts 6, performance constraint frame 4 rotates the back and when folding back and front supporting foot rest 2,3 to collapsed position, this positioning seat 25,35 is positioned at accommodation space 53 positions of restriction seat 5, at this moment, because this restriction seat 5 is subjected to stopping of positioning seat 25,35 sides, and can't be subjected to elastic recovery to the standing place; After the operator draws back back and front supporting foot rest 2,3 and is deployed condition, 5 of this positioning seats have been rotated away with back and front supporting foot rest 2,3, at this moment, this 5 of restriction seat can utilize this elastic parts 6 and automatically return to the standing place, and then, reach the effect of handled easily with this by top this positioning seat 25,35 of pulling.
For avoiding the improper operation limit rotation of operator frame 4, can between this is to restriction frame 4, rotating Safety knob for electric appliance 7 be arranged device in the middle of the present embodiment, utilize two long ends 71 of this Safety knob for electric appliance 7 to stop that this is rotated restriction frame 4; The operator desired folding back and front supporting foot rest at 2,3 o'clock, then rotated Safety knob for electric appliance 7 earlier, made its two ends break away from stop limits frame 4, rotated and provide operation to drive restriction frame 4, to reach safe effect.
