Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
Fig. 1 to 8 schematically show a patient-use cat ladder with a braking function according to an embodiment of the present invention.
As shown in fig. 1 to 8, the patient-inconvenient-movement cat ladder with a braking function includes a frame 1, and a backrest 2, a seat cushion 3, a front wheel 4, a rear wheel 5, and a base 6 mounted to the frame 1. The cushion 3 is mounted above the base 6, and the rear wheels 5 are mounted on both sides of the base 6. The front wheel 4 is positioned in front of the rear wheel 5 and the lower end surfaces of the front wheel and the rear wheel are positioned on the same horizontal line.
The ladder stand of the present embodiment further includes a brake device 7. The braking device 7 is mounted on the base 6 and matched with the rear wheel 5, and is used for braking the rear wheel 5.
The brake device 7 of the present embodiment includes a lever drive wheel assembly 71, a brake block assembly 72, a fixing piece 73, and a link piece 74. The rear wheel 5 is rotatably mounted to the fixing piece 73, and the rear wheel 5 of the present embodiment is rotatably mounted to the fixing piece 73 via a rotation shaft 8. The fixing piece 73 is attached to the base 6 by a fastener such as a screw. The lever driving wheel assembly 71 is rotatably mounted to the fixing piece 73 through a first pin 76. The brake pad assembly 72 is rotatably mounted to the stator 73 by a second pin 77 and cooperates with the rear wheel 5. One end of the link plate 74 is hinged to the brake pad assembly 72, and the other end is hinged to the lever drive wheel assembly 71. The brake pad assembly 72 is capable of braking the rear wheel 5 under the drive of the lever drive wheel assembly 71.
The brake pad assembly 72 includes a brake pad 721, a brake pad holder 722, and a stationary auxiliary lever 723. The brake pads 721 are mounted to the brake pad holder 722 and cooperate with the rear wheel 5. One end of the fixing auxiliary rod 723 is mounted to the brake pad fixing seat 722, and the other end is mounted to the fixing plate 73 together with the brake pad fixing seat 722 through the second pin shaft 77. The brake pad fixing seat 722 and the middle part of the fixing auxiliary rod 723 are connected through a fourth pin 724, and the fourth pin 724 is in sliding fit with the fixing plate 73. One end of the linkage piece 74 is sleeved on the fourth pin 724, and the other end is hinged with the lever driving wheel assembly 71. Thus, the brake pad assembly 72 of the present invention operates on the following principles: the wheel of the lever driving wheel assembly 71 drops down to drive the linkage piece 74 to pull the fourth pin 724 to move downwards, and then drive the brake block fixing seat 722 and the fixing auxiliary rod 723 to rotate together by taking the second pin 77 as a rotating shaft to drive the brake block 721 to swing and act on the surface of the rear wheel 5 to limit and brake the rear wheel 5.
The fixing piece 73 is provided with an arc-shaped limiting groove 731, and the fourth pin 724 is matched with the limiting groove 731. Therefore, the linkage piece 74 can drive the fourth pin shaft 724 to slide in the limiting groove 731, and the movement is stable.
One end of the linkage piece 74 is sleeved on the fourth pin 724, and the other end is connected with the lever driving wheel assembly 71 through the third pin 78.
The lever driving wheel assembly 71 includes a support bracket 711 and a lever driving wheel 712. The lever driving wheels 712 are rotatably installed at both ends of the supporting frame 711. The support bracket 711 is connected to the fixing piece 73 via a first pin 76, and the support bracket 711 is connected to the coupling piece 74 via a third pin 78. Therefore, when the previous lever driving wheel 712 in the forward direction falls, the next lever driving wheel 712 is driven to rise, but no matter which lever driving wheel 712 falls, the linkage piece 74 is driven to pull the fourth pin 724 downwards, so that the brake pad 721 is driven to brake the rear wheel 5.
The support frame 711 includes two support pieces 711a, and the two support pieces 711a are connected by a fastener such as a screw. The lever driving wheel 712 is rotatably mounted to both end portions of the supporting piece 711a by pins, rivets, or the like and is located outside the supporting piece 711 a.
The brake device 7 of the present embodiment further includes a tension spring 75. One end of the tension spring 75 is connected to the first pin 76, and the other end is connected to the fourth pin 724. The tension spring 75 is located between the two support pieces 711 a. Thereby, the tension spring 75 can play a role of resetting and buffering.
The number of fixing pieces 73 in the present embodiment is two, and the two fixing pieces 73 are provided outside the two supporting pieces 711a, respectively. The first pin 76, the second pin 77 and the fourth pin 724 all pass through the two fixing pieces 73.
Since the number of rear wheels 5 is two in this embodiment, the number of brake devices 7 is also two. The two braking devices 7 are respectively arranged at the left side and the right side of the base 6 and are respectively matched with the two rear wheels 5.
The stair climbing machine of the embodiment further comprises an upper handrail 9 and a lower handrail 10, wherein the upper handrail 9 is arranged on the frame 1 and is positioned above the backrest 2, the upper handrail 9 is provided with a control button, and the stair climbing machine is mainly used for being operated by a caretaker and is controlled, pushed and pulled through the upper handrail 9. The lower armrests 10 are arranged on the backrest 2 and above two sides of the cushion 3, and the lower armrests 10 are mainly used for placing arms of users with inconvenient movement and play a supporting role.
The invention provides a ladder stand with a brake device 7, and the working principle of the brake device 7 is as follows:
When the ladder stand runs on a stable road surface, the lower end surfaces of the two lever driving wheels 712 of each brake device 7 are positioned on the same horizontal plane with the front wheels 4 and the rear wheels 5, at the moment, the brake pads 721 are far away from the rear wheels 5, namely, the brake pad assembly 72 cannot limit the rear wheels 5, and at the moment, the wheels of the lever driving wheel assembly 71 can roll on the road surface like the front wheels 4 and the rear wheels 5;
As shown in fig. 8, when a person with inconvenient movement is pushed to a stair by using the stair climbing machine, no matter going upstairs or downstairs, the front lever driving wheel 712 (the lever driving wheel 712 on the left side in fig. 8) falls down, the lever driving wheel 712 (the lever driving wheel 712 on the left side in fig. 8) pulls the linkage piece 74 downwards, the linkage piece 74 drives the fourth pin shaft 724 originally positioned at the top end of the limiting groove 731 to slide downwards to the bottom end, the fourth pin shaft 724 drives the brake pad fixing seat 722 and the fixing auxiliary rod 723 to rotate along the second pin shaft 77 on the right end, and further drives the brake pad 721 on the left end to move downwards, the brake pad 721 acts on the surface of the rear wheel 5, so that limit braking can be performed on the rear wheel 5, and at this time, the rear wheel 5 cannot rotate, namely, when going upstairs or downstairs, the rear wheel 5 cannot rotate, and the safety of the whole stair climbing machine is effectively improved.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
