Further, the drive member 42 is driven by operating the second operation member, and the drive pin 43 is moved by driving the drive member 42, whereby the brake assembly 44 is positioned at the first lock position. Or the first lock position is changed to the second lock position.

  Subsequently, as shown in FIGS. 4 to 7, the second operation member and the drive member 42 are preferably integrally formed, and one end of the first connection member 22 is the first operation member. 21 and the other end protrudes from the brake boss 41 through the wheel holder 12 and is connected to the second operating member through the lower side of the brake boss 41 (see FIG. 5). Therefore, the first operating member 21 is connected to the driving member 42 by the first connecting member 22 and the second operating member, and when the first operating member 21 is operated, the first connecting member 22 and the second connecting member 22 are connected. The driving member 42 is driven to rotate by the operation member, whereby the main brake mechanism 40 and the sub brake mechanism 50 are positioned at the first lock position, and the drum brake is realized. In another embodiment, the main brake mechanism 40 and the sub brake mechanism 50 are positioned at the first lock position, and the disc brake is realized.

  As shown in FIGS. 5 and 6, the wheel 14 has a brake hub 141 provided with a plurality of brake lock holes 1411, and the main brake mechanism 40 is located at the first lock position. When the brake assembly 44 comes into contact with the inner wall of the brake hub and the main brake mechanism 40 changes from the first lock position to the second lock position, the drive pin 43 is engaged with the brake lock hole 1411.

  Further, as shown in FIGS. 6 and 7, the main brake mechanism 40 further includes a first elastic member 45, and a drive pin 43 is movably provided in the brake boss 41. The elastic member 45 is in contact with the drive pin 43 and the brake boss 41. The first elastic member 45 is used for resetting the drive pin 43.

  6-9, the brake assembly 44 has a brake plate drive member 441 and brake plates 442 that are alternately fixed to the edges of the brake plate drive member 441 and protrude to both sides thereof. doing. The brake plate drive member 441 is provided with a driven surface 4411 (details will be described later) for fitting with the drive pin 43 at one end and a pivot hole 4412 at the other end. A connecting member (not shown) pivots on the side wall of the wheel 14 adjacent to the brake boss 41 after the pivot hole 4412 is formed. The driven surface 441 of the brake plate drive member 441 abuts on the drive pin 43, and the slide of the drive pin 43 pushes the brake plate drive member 441 to pivot, and pivots outward to extend the brake plate. The surface of 442 comes into contact with the inner wall of the brake hub 141 to realize a drum brake. At this time, the main brake mechanism 40 is located at the first lock position. When the drive pin 43 continues to slide and engages with the brake lock hole 1411, the main brake mechanism 40 is positioned at the second lock position, and the drum brake and the wheel lock are realized.

  The brake plate 442 is preferably made from a soft material, such as rubber. As a result, the brake plate 442 has high friction resistance.

  Further, as shown in FIGS. 8 to 10 and 12, the brake assembly 44 includes both brake plate drive members 441 that are constricted or semicircular. Both brake plates 4412 are fixed to the respective edges of both brake plate drive members 441. One end of each of the brake plate drive members 441 is pivotally connected to the side wall of the brake boss 41 via a pivot hole 4412. One end of each brake plate drive member 441 that is apart from the pivot hole 4412 is curved and protrudes to form a driven surface 4411, and the driven surface 4411 is substantially the same as the drive pin 43.

The portion is in contact with the drive surface 432. When the drive pin 43 is slid, the drive surface 432 pushes the end of the driven surface 4411 and both brake plate drive members 441 pivot and expand to the outside, so that the surface of the brake plate 442 contacts the inner wall of the brake hub 141. The drum brake is realized by contact, and the main brake mechanism 40 is positioned at the first lock position. When the drive pin 43 continues to further slide, follower surface 4411 surrounds the protruding portion 431, engaging end 433 of the two drive pins 43 are engaged with the brake lock hole 1411 protrudes from both the brake plate drive member 441 Thus, the drum brake and the wheel lock are realized. At this time, the main brake mechanism 40 was changed from the first lock position to the second lock position.

Brake assembly 44 further includes a second elastic member 443 which is used to reset the brake plate drive member 441, although, respectively that of the two ends of the second elastic member 443, the driven surfaces of both the brake plate drive member 441 4411 Connected to the near end.

  Further, as shown in FIGS. 11 and 12, a spiral drive slope 421 is provided on the side wall of the drive member 42, and a positioning groove located on one side of the drive slope 421 is further provided on the side wall. The drive slope 421 is in contact with the end of the drive pin 43 opposite to the engagement end 433. When the drive member 42 rotates, the drive slope 421 pushes and slides the drive pin 43, and when the drive pin 43 engages with the positioning groove 422 beyond the highest point of the drive slope 421, the drive pin 43 moves to the wheel 14. The main brake mechanism 40 is engaged with the brake lock hole 1411 so that the main brake mechanism 40 is positioned at the second lock position.

  In the first embodiment of the present application, when the first operating member 21 is operated by setting the movement stroke of the first operating member 21, the driving pin 43 is pushed and moved only by the driving slope 421. By operating the operation member 21, the main brake mechanism 40 is positioned only at the first lock position, and the drum brake is realized. Then, by operating the second operating member, the drive slope 421 pushes and moves the drive pin 43, and the drive pin 43 is engaged with the positioning groove 422 beyond the highest point of the drive slope 421. At this time, the drum brake and the locked state of the wheel are realized. That is, the operation of the second operating member causes the main brake mechanism 40 to be positioned at the first lock position or to switch from the first lock position to the second lock position.

  Hereinafter, the braking process of the main brake mechanism 40 of the present invention will be described with reference to FIGS. 5 to 8 and FIGS. 13 to 15.

  As shown in FIG. 13, when the main brake mechanism 40 is in a normal state, the engagement end 433 of the drive pin 43 is located in the brake boss 41, and the driven surface 4411 of the brake plate drive member 441 is connected to the drive surface 432. It is in contact.

  When the first operating member 21 is operated, the first operating member 21 causes the second operating member to be interlocked via the first connecting member 22, and the second operating member is moved in the direction of the arrow shown in FIG. 5. And thereby the drive member 42 is rotated. In this process, when a horizontal pressing force is generated from the driving slope 421 of the driving member 42 to the driving pin 43, the driving pin 43 is pushed by the force, and the driving pin 43 slides horizontally, and the driving pin 43 slides. The driving surface 432 pushes the end of the driven surface 4411, and both driving members 431 pivot and extend to the outside, whereby the surface of the brake plate 442 contacts the inner wall of the brake hub 141 to realize drum braking. The In this process, the first elastic member 45 is compressed. When the drive pin 43 comes into contact with the top of the drive slope 421, the main brake mechanism 40 is positioned at the first lock position as shown in FIG.

  In the present invention, the driving member 42 is rotated only by a certain angle by the movement stroke of the first operating member 21, that is, the driving pin 43 is only moved from the lowest part to the highest part of the driving slope 421. By operating the first operation member 21, the main brake mechanism 40 is positioned only at the first lock position.

  When the operation of the first operation member 21 is released, the second operation member is reset, the first elastic member 45 is also reset, and a reset force is generated on the drive pin 43. Slide to return to the normal state shown in FIG. At this time, since the pressing of the stroller can be resumed quickly, it is extremely convenient for the user who presses the stroller.

  When the second operation member is operated, the drive member 42 is rotated by the second operation member, and the drive pin 43 is driven to slide by the rotation of the drive member 42. Finally, the main brake mechanism 40 is moved. It comes to be in the 1st lock position. Since the process has been described above, its detailed description is omitted here.

  In the first lock position shown in FIG. 14, when the second operating member is continuously driven and rotated, when the driving pin 43 is pushed and moved by the second operating member, the driving pin 43 is engaged. The end 433 is engaged with the brake lock hole 1411 through the brake boss 41. Thereby, the lock | rock of the wheel 14 is implement | achieved. At this time, when the highest point of the drive slope 421 exceeds the drive pin 43, the end of the drive pin 43 is engaged in the positioning groove 422, and the main brake mechanism 40 is moved to the first position as shown in FIG. The lock position is changed to the second lock position. In this case, since the stroller march is stopped and fixed at one position, reliability and safety when using the stroller are guaranteed.

  When the second operating member is operated to the opposite side, the highest point of the driving slope 421 exceeds the driving pin 43 due to the pivot of the second operating member, and the end of the driving pin 43 is detached from the positioning groove 422. Then, the first lock position shown in FIG. 14 and the normal state shown in FIG. 13 can be restored.

  Next, the sub brake mechanism 50 of the present invention will be described with reference to FIGS.

  The sub brake mechanism 50 includes a brake boss 51, a drive member 52, a drive pin 53, a brake assembly 54, and a first elastic member 55. The brake assembly 54 includes a brake plate driving member 541, a brake plate 542, and a second elastic member 543. In addition, since the structure and attachment method of the brake boss 51, the drive pin 53, the brake assembly 54, and the 1st elastic member 55 are the same as the main brake mechanism 40, description here is abbreviate | omitted.

  As shown in FIG. 18, the configuration and mounting method of the drive member 52 is slightly different from the drive member 42 of the main brake mechanism 40 described above. Specifically, the drive member 52 is installed in a rotational manner, and the rotational direction of the drive member 52 is opposite to the rotational direction of the drive member 42 of the main brake mechanism 40. The interlocking member 60 has one end connected to the driving member 52 and the other end connected to the second operation member. On the side wall of the drive member 52, a drive slope 521 that contacts the end of the drive pin 53 is provided. As described above, when the first operating member 21 or the second operating member is operated, the driving member 52 is synchronously rotated by the interlocking member 60 to drive the brake assembly 54, whereby the drum brake or the wheel is locked.

Simultaneously with the rotation of the driving member 42, the driving member 52 is rotated by the interlocking member 60. By the rotation of the driving member 52, the driving slope 521 pushes the driving pin 53 to move the driving pin 53 horizontally, thereby driving. The pin 53 pushes both the brake plate driving members 541 and pivots them to expand to the outside. As a result, the surface of the brake plate 542 comes into contact with the inner wall of the brake hub 141 to realize a drum brake. At this time, the sub brake mechanism 50 is positioned at the first lock position. The rotation directions of the drive members 42 and 52 are opposite.

  Subsequently, when the second operating member is operated, the driving member 52 continues to push the driving pin 53, and finally the driving pin 53 is engaged with the brake lock hole 1411 to realize the locking of the wheel. The drive pin 53 is also engaged in the brake lock hole 1411 to achieve the lock, and the sub brake mechanism 50 is switched from the first lock position to the second lock position.

As described above, according to the brake device of the present invention, the brake device includes the first brake member 20 provided on the handle holder 11 of the stroller, and the second brake member 30 provided on the wheel holder 12 of the stroller.
