Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model content is described further.
As shown in Fig. 1 to 7, the Multifunctional folding chair for traveling of the present embodiment, comprising: underframe 1, bracing frame 2, seat frame 3 and back rest 4.
On bracing frame 2, be provided with for limiting underframe 1 fixed support block 26 of angle that rotates backward, and be provided with the power assisted support rod 11 that can rotate relative to bracing frame 2 front and back.Power assisted support rod 11 is the Y type power assisted support rods 11 that are made up of left bar 111, right bar 112 and montant 113, and the length of montant 113 equates with the thickness of underframe 1.Power assisted support rod 11 is arranged between the left support part 21 and right support part 22 of bracing frame 2 by 2 the 5th bearing pins 9.In power assisted support rod 11, be provided with for locking underframe 1 rotational angle and the locking piece of angle of rotating backward forward.In the present embodiment, locking piece is lock hook 25.Lock hook 25 one end are with the jag 252 of locking, and the other end is hinged on the inside of power assisted support rod 11 by the 6th bearing pin 10.Jag 252 is outstanding positions of the hook formation that is made up of inclined plane 254 and lock face 253.In lock hook 25, be also provided with for the elastic component to original position by lock hook 25 clawbacks, in the present embodiment, elastic component is torsion spring 251, and torsion spring 251 is arranged on power assisted support rod 11 by the 6th bearing pin 10 with lock hook 25.So lock hook 25 can rotate to left and right relative to power-assisting supporting frame 11.The inwall of lock hook 25 is close in one end of torsion spring 251, and the other end stretches out the inwall that shell is close to power assisted support rod 11.On power assisted support rod 11, be also provided with the opening that makes the jag 252 of lock hook 25 can stretch out power assisted support rod 11, now, under the active force of torsionspring 251, lock hook 25 is close to the inwall of power assisted support rod 11, its jag 252 stretches out power assisted support rod 11 from the opening part of power assisted support rod 11, and lock hook 25 is in original position.
Back rest 4 links together with seat frame 3 by 2 the 3rd bearing pins 7, so back rest 4 can rotate to front and back relative to seat frame 3.Maximum open angle between back rest 4 and the seat frame 3 of the present embodiment is 105 °, and the sitting posture of such angle human body can be pleasant.
On bracing frame 2, be also provided with for locking the rotate backward back rest locking piece of angle of back rest 3.In the present embodiment, described back rest locking piece adopts hand-screw screw 24.Hand-screw screw 24 is provided with the jump ring 241 that passes in and out distance for limiting picking screw 24.In the time that seat frame 3 and back rest 4 open to maximum angle, hand-screw screw 24 is screwed in the seat lock hole 41 on back rest 4, now, the 3rd bearing pin 7 becomes line with 24 two, picking screw, thus the state of locking back rest 4.When seat frame 3 rotates backward, together with amounting to back rest 4 after, picking screw 24 is screwed in hand buggy lock hole 42, thus the state of locking seat frame and back rest.
The product of the present embodiment has three state pattern:
Seat mode: as shown in Figure 1, underframe 1 rotates backward and puts in place, is subject to the position-limiting action of fixed support block 26, thereby bracing frame 2 can upwards erect and grantee's body weight; Power assisted support rod 11 snaps in the rear locking cover 15 on underframe 1, thereby auxiliary support frame 2 grantee's body weight forward a position to after underframe 1 is in; Seat frame 3 rotate in place forward, is subject to stopping of cross-member 23, and therefore seat frame 3 can underwriter's body weight.Back rest 4 opens to maximum angle with seat frame 3, hand-screw screw 24 screws in seat lock hole 41, can not relatively rotate, now between back rest 4, seat frame 3 and bracing frame 2 again, relatively fixing between two between underframe 1, bracing frame 2, seat frame 3, back rest 4, present the form of general seat.
Hand buggy pattern: as shown in Figure 2, underframe 1 turns to forward proper angle, power assisted support rod 11 snaps in the front locking cover 14 of underframe 1, make underframe 1 relatively bracing frame 2 rotate backward, underframe 1 is in the forward position that puts in place.And wheel 13 and support member 12 with the rotation of underframe 1 towards ground.Together with seat frame 3 is amounted to back rest 4, and hand-screw screw 24 is screwed in hand buggy lock hole 42, therefore can not relative motion between seat frame 3, back rest 4 and bracing frame 2.Under this state model, relatively fixing between two between underframe 1, bracing frame 2, seat frame 3, back rest 4, and present the form of general hand buggy.
Storage mode: as shown in Figure 3, when product switches to storage mode by chair pattern, underframe 1 rotates forward with bracing frame 2 to be amounted to; Together with seat frame 3 is amounted to back rest 4; Together with the entirety that seat frame 3 forms with back rest 4 is amounted to bracing frame 2.Under this pattern, the volume of this product dwindles greatly.
In hand buggy pattern, wheel 13 and support member 12 with the rotation of underframe 1 towards ground.Because of the plane of 3 compositions of wheel 13 and support member 12, can make the hand buggy can firm must placement on the ground without any helping.
As shown in Figure 7, release lever 27 and lock hook 25 all link together with the 6th bearing pin 10.If desired remove the lock-out state of underframe 1, only release lever 27 need be rotated counterclockwise, because of the annexation of release lever 27 and lock hook 25, lock hook 25 will clockwise rotate, until the jag 252 of lock hook 25 turns to the inside of power assisted support rod 11, now, power assisted support rod 11 can be extracted out from the locking cover of underframe 1, be removed the lock-out state of underframe 1.
Hand-screw screw 24 is provided with the jump ring 241 that is positioned at bracing frame 2 inside, thereby limit the turnover distance of picking screw 24, even in actual use, people, also also not worrying that hand-screw screw 24 can lose without use the fixing seat framves 3 of hand-screw screw 24 and back rest 4 in the situation that, cause the form solid failure between seat frame 3 and back rest 4.
By power assisted support rod 11 auxiliary support frame 2 grantee's body weight, compared with existing folding seat, the crowd that this folding seat can be applicable is wider; Y type power assisted support rod 11 and the del that the cross-member 23 of bracing frame 2 forms, can reduce rocking of folding seat effectively, allows the form of folding seat keep more reliable.
