Detailed Description
The embodiment of the adjustable-orientation stroller frame 0 of the seat of the present invention shown in fig. 1 and 2 is composed of a first support frame 1, a second support frame 2, a seat support 3, a linkage frame 4 and a seat 5.
The lower end of the first support frame 1 of the present embodiment is provided with at least one first wheel 11, while the second support frame 2 is rotatably connected with the first support frame 1 and is provided with at least one second wheel 21 at the lower end, thus forming a frame body which can be folded and unfolded and can be pushed.
As shown in fig. 5 and 6, the seat support 3 can move back and forth along the first support frame 1, and the linkage frame 4 is rotatably connected between the seat support 3 and the second support frame 2; when the seat support 3 moves toward the lower end of the first support frame 1, the linkage frame 4 drives the second support frame 2 to rotate and pivot the second support frame 2 toward the first support frame 1 at the same time, so as to generate a folding result of folding the vehicle.
On both sides of the seat 5, a lever 51 is provided, which lever 51 can be locked in a rearwardly extending position 510 and can be pivoted upwards to an upright position 520 after unlocking. As shown in fig. 12 and 13, the lower end of the seat 5 is rotatably connected to the seat support 3. A first locking mechanism 52 can be arranged between the lower end of the seat 5 and the seat support 3 and is interlocked with the control handle 51; when the lever 51 is locked at the rearward inclined position 510, the first locking mechanism 52 automatically enters a locked state, so that the seat 5 cannot be turned relative to the seat support 3; when the lever 51 is pivoted upward to the upright position 520 after unlocking, the first locking mechanism 52 is driven directly or through a linking member (not shown), and the locking state of the first locking mechanism 52 to the seat 5 is released, and the seat 5 is pivoted on the seat support 3 to change the direction.
In terms of specific structure, the first locking mechanism 52 can refer to the technical solutions disclosed in chinese ZL200620062124.3 and TWM 407866U. The chinese ZL200620062124.3 patent uses a positioning element (not shown) to be locked to the positioning position 31 of the receiving seat 3, so that the seat 2 is controllably oriented toward the front or rear of the vehicle, and uses the release mechanism 5 to disengage the positioning element from the positioning position 31, so as to release the locked state between the seat 2 and the receiving seat 3, and uses the handle 10 to push the seat 2 to change its orientation. In the present embodiment, the release mechanism 5 is directly replaced by the lever 51. It is obvious that in other embodiments it is of course also possible to additionally mount a release mechanism 5 on the control handle 51, which is not described in detail here.
The TWM407866U patent uses the handlebar stop switching mechanism 7 to drive the stop blocks 71, 72 to extend and retract when the seat 2 rotates, so as to mutually and limitedly abut the limiting block 17 on the control handle 10, thereby realizing the pivotal switching of the control handle 10 between the cart position 20 and the stop position 4.
It should be noted that the technical problem to be solved by the invention is to realize that the seat can be conveniently folded without being disassembled aiming at the baby carrier with the rotatable seat function. Therefore, the key point of the present invention is not how the specific structure of the first locking mechanism 52 is, but the relative pivoting relationship among the seat (5), the seat support (3), the control handle (51), the second support frame (2), the first support frame (1) and the linkage frame (4) is that the stroller frame created by the present invention is folded without the seat being disassembled, so that the condition that the control handle and the underframe of the seat and the stroller frame interfere with each other in the folding process is avoided, and the seat, the stroller frame and the wheels can be skillfully utilized to support in standing when the folding is completed, and the stroller frame is also supported in a horizontal manner, so that various standing modes are provided, and the use of the storage space is improved. In fact, the specific actuation structure and principle of the first locking mechanism 52 may be conventional, or may be a completely new unlocking structure. Whether the conventional technical means or the brand new unlocking design structure can only realize the interaction relation among the seat (5), the seat supporting seat (3), the control handle (51) and other parts described in the previous section.
The control handle 51 may include a retractable portion 530 to adjust the length, as shown in fig. 11 and 13, to extend as a stroller handle during deployment of the stroller frame 0 with the adjustable orientation of the seat or when the stroller frame 100 is in a standing use position, to shorten the stroller frame 0 with the adjustable orientation of the seat during retraction, thereby reducing the space occupied by the stroller frame.
The seat of this embodiment has a stroller frame 0 with adjustable direction, and a second locking mechanism 12 and a retraction control mechanism 14. The second locking mechanism 12 is optionally disposed between the first support frame 1 and the seat support 3 and between the first support frame 1 and the second support frame 2, and automatically enters a locked state when the stroller frame 0 with the adjustable direction of the seat is in a standing use state 100.
In the embodiment shown in fig. 1, the second locking mechanism 12 is disposed between the first support frame 1 and the second support frame 2, so that the first support frame 1 and the second support frame 2 cannot rotate when in a locked state. As shown in fig. 14, the second locking mechanism 12 is disposed between the first support frame 1 and the seat support 3, and in the locked state, the seat support 3 cannot slide along the first support frame 1, so that the first support frame 1, the seat support 3 and the second support frame 2 cannot move relatively, and the first support frame 1, the second support frame 2, the seat support 3 and the linkage frame 4 are converted into a locked chain (locked chain) state in which they cannot move freely.
The vehicle receiving control mechanism 14 is directly or indirectly linked with the second locking mechanism 12, and when operated, the second locking mechanism 12 is unlocked to start continuous operation as shown in fig. 5 to 7 and 8 to 10. In detail, when the stroller frame 0 of the present embodiment is in the use state 100 of Zhang Li, the user can activate the stroller folding control mechanism 14 to release the locking state between the first support frame 1 and the second support frame 2, and the seat support 3 and the seat 5 are moved downward along the first support frame 1 under the influence of gravity, the linkage frame 4 pivots and pulls the second support frame 2, so that the second support frame 2 pivots towards the first support frame 1, the stroller folding state is completed, and finally the seat 5 and the at least one first wheel 11 are used to support and stand together, thereby improving the space occupation.
It should be specifically noted that the specific actuation structures and principles of the release mechanism 14 and the second locking mechanism 12 are conventional, for example, a more common release structure is disclosed in the specification [ 0025 ] and fig. 5 of the chinese ZL201120341193.9 patent. The applicant considers that specific unlocking actuation structures can be various, and can adopt the existing conventional structure or redesign a brand new unlocking structure; however, the specific unlocking structure is not critical to the technical solution of the present invention, and conventional technical means or completely new unlocking design structure may be used as long as the locking mechanism 14 and the second locking mechanism 12 can be linked. When the car is unfolded, as shown in fig. 11, the user only needs to pull up the control handle 51 of the seat 5 to move the seat support 3 and the seat 5 along the upper end of the first support frame 1, then the linkage frame 4 will automatically open the second support frame 2 and the first support frame 1, and finally the second locking mechanism 12 will automatically lock the first support frame 1 and the second support frame 2, so that the stroller frame 0 with adjustable direction of the seat of the present embodiment is fixed in the use state 100 of Zhang Li. When the baby carriage framework (0) is in an unfolding state, the seat (5) and the first support frame (1) are respectively positioned at two sides of the control handle (51), and when the baby carriage framework (0) is in a folding state, the seat (5), the control handle (51) and the second support frame (2) are partially stacked on the first support frame (1).
As shown in fig. 4, the retracting control mechanism 14 of the present embodiment is operatively disposed at the rear side of the stroller frame 0 with the adjustable direction of the seat, and the second locking mechanism 12 is unlocked by direct or indirect linkage.
As shown in FIG. 3, in two alternative embodiments, the retraction control mechanism 14 is a webbing 140 disposed on the rear side of the stroller frame 0 with the seat adjustable, where the user can grasp by hand, and when pulled, the second locking mechanism 12 is actuated by a flexible member 141 of a conventional cable or linear material. Another variation is implemented with a generally rotatable member 142 that is rotated to unlock the second locking mechanism 12 by pulling a flexible member 143. The rotatable member 142 may be implemented as a handle as shown in fig. 4, operatively disposed near the upper end of the second support frame 2, or as a pedal (not shown) operatively disposed near the lower end of the second support frame 2.
Referring to fig. 5 to 7 again, the first support frame 1 is provided with a pair of guiding devices 110, and the seat support 3 is guided by the pair of guiding devices 110 to move back and forth along the first support frame 1. The guide 110 may be implemented as a rail, channel or slide, etc. design, such as the left and right opposing channels shown, allowing both sides of the seat support 3 to extend into the pair of left and right opposing channels 111 to slide back and forth.
By the implementation of the invention, the baby carriage framework with the rotatable seat and the direction adjustable seat can be realized, the seat is not required to be disassembled during the folding, the seat is not required to be reinstalled during the folding, the seat 5 and at least one first wheel 11 can be used for supporting and standing together after the folding, and the utilization condition of the storage space is improved.
