Description

Chair foot subassembly and seat

Technical Field

The utility model relates to a thing to sit on field, in particular to chair foot subassembly and seat.

Background

The chair has strong practicability and can be found in all rooms, and the chair has the main function of facilitating people to have a rest. At present, the requirements of people on seats are higher and higher, particularly, incorrect sitting posture that feet are hung off the ground often occurs when children learn, and due to the fact that the positions of foot rests are not correct, the sitting posture problem of the children is easily caused, and the bone development of the children is influenced. Moreover, children often step on the chair because feet cannot step on the ground, the chair is easy to be polluted, and even some children fall down because the children cannot step on the ground, so the children are very unsafe.

Therefore, the leg rest part of the existing child learning chair is arranged on the chair leg, so that the chair is safer and healthier when being used by children. However, if a foot rest rod is directly designed on the chair foot, one is more obtrusive, which affects the shape of the chair and is not beautiful; moreover, how the leg rest rod is connected with the chair leg is also a problem, and the stability of the structure needs to be ensured; if the screw connection is directly adopted, the screw is exposed outside, and the appearance is not attractive; in addition, the surface of the common chair leg is always provided with a certain radian, and the problem of the stable connection of the foot rest rod and the chair leg is also a problem. Therefore, the self-modeling of the structural seat, the connection between the chair feet and the leg rest rods, the structural stability and the like need to be comprehensively considered.

CN 201821945614.7's chinese utility model patent discloses a "take pedal chair foot of adjustable height and study chair" includes the base, the top fixed mounting of base has the lift post, first slider has been cup jointed to the outer wall of lift post, the right side joint of first slider has the slide bar, the right-hand member fixed mounting of slide bar has the footboard, the left side movable mounting of first slider has the first fixing bolt who runs through first slider and extend to lift post outer wall, the top fixed mounting of lift post has the bedplate, the top fixed mounting of bedplate has the handrail, the top of bedplate and the right side fixed mounting who is located the lift post have the crank, the bottom fixed mounting of bedplate has the second slider. This take pedal chair foot of adjustable height and study chair, top fixed mounting through the bedplate has the foam-rubber cushion, and the right side fixed mounting of backplate has the rubber pad for children are when studying, and more comfortable of sitting, better correction children's position of sitting reaches the effect that reduces children's hunchback and myopia. The chair is characterized in that a sliding rod is arranged on a lifting column, and a pedal is arranged on the sliding rod; thereby enabling the seat to have a leg rest function; however, the slide bars are arranged on the lifting column, so that the structure is abrupt, and the shape of the chair is influenced; and the structure has the hidden trouble of instability.

Disclosure of Invention

The utility model overcomes the defects in the prior art, and provides a chair leg component and a chair which have the function of a leg supporter and beautiful and stable structure; the chair leg component is provided with the leg rest rod at the front end of the leg rod, and the leg rest rod and the rear cross rod at the rear part also jointly play a role in stabilizing the leg rod, so that the chair leg component is rectangular in shape, and simple and regular in structure; the foot rest rod is connected with the foot rod through a foot cover, and the foot cover can play a role in decoration and covering; and closely laminate between foot lid and the foot pole, peg graft the cooperation between connector on the bracket pole and the foot lid is inseparable to make and put and connect closely between foot pole, foot lid, the foot pole three, make the sound construction of putting the foot pole.
