Manual stair climbing vehicle

Abstract: The invention discloses a manual stair climbing vehicle. A back leg and a front leg are arranged in parallel one after the other; a front pipe of the back leg is inserted into the front leg in a way of moving vertically; a gear elevating structure is arranged between the front leg and the back leg; a gas spring structure is arranged in the front pipe of the back leg; the top end of the gas spring structure is connected with the upper part of the front pipe of the back leg; the bottom end of the gas spring structure is connected with the bottom of the front leg; a front leg support leg is connected with the front leg, and comprises a front leg front support leg which is positioned in front of the front leg and a front leg back support leg which is positioned behind the front leg; a back leg support leg is connected with the back leg, and comprises a back leg front support leg which is positioned in front of the back leg and a back leg back support leg which is positioned behind the back leg; a support leg elevating structure comprises a first elevating structure and a second elevating structure; a vehicle beam is connected to the upper end of the back side of the back leg; and U-shaped handlebar can be connected to both sides of the front leg in a way of rotating forward and backward. The manual stair climbing vehicle has the advantages of pure mechanical structure, no need of any external energy source, environmental friendliness, simple structure, small size, light weight, low cost, labor-saving operation and saving in energy sources, and can be directly used for dragging heavy objects to go downstairs.

Low-gravity-center backward-inclined stair climbing wheelchair

Abstract: The utility model relates to a low-gravity-center backward-inclined stair climbing wheelchair. The stair climbing wheelchair is provided with a frame, wherein two hand-propelled chair wheels are respectively arranged on two sides of the frame; a universal wheel corresponding to the hand-propelled chair wheels on the two sides is arranged at the front end of the lower part of the frame; a chair seat is arranged in the middle of the frame; a chair cushion is arranged on the chair seat; a pedal plate is arranged at the front end of the frame; a crawler-type stair climbing device is arranged on the frame, a crawler, a crawler expansion wheel, a crawler driving wheel and a crawler driving motor are arranged at a power driving part of the crawler-type stair climbing device; and one end of the crawler-type stair climbing device is in control connection with the frame through a crawler contraction and release driven arm, a crawler contraction and release driving arm and a contraction and release motor, and the other end is in hinge connection with the frame through a crawler movable support arm. The low-gravity-center backward-inclined stair climbing wheelchair is suitable for stair climbing, and has the advantages of reasonable structure, scientific design, stability in running, convenience in operation, low gravity center, safety and reliability.

Three-foot stair climbing device and implementing method thereof

Abstract: The invention discloses a three-foot stair climbing device for helping the elder and the disabled in a corridor and an implementing method of the three-foot stair climbing device. A gravity adjusting device, a battery module and a control system are arranged in a working table, and according to the gravity adjusting device, a stepping motor is adopted to drive a lead screw to adjust the front-back position, relative to the working table, of a mass block, so that the stability of the gravity of the device in the stair climbing process is ensured; according to a front-back and up-down telescopic device, three main electric push rods vertically distributed are adopted so that three feet can ascend or descend, and two auxiliary electric push rods horizontally arranged are adopted so that the three feet can move horizontally in the stair climbing process; according to a driving traveling device, a rear wheel hub motor is adopted for driving, front wheels and middle wheels are steering wheels, a ratchet mechanism capable of being opened or closed is arranged on each wheel, on one hand, the safety of the stair climbing process is ensured, on the other hand, ratchet reverse locking is used for cooperating with the auxiliary electric push rods to achieve different moving combinations of the three feet, the three-foot stair climbing device can assist in stair climbing and can be used for riding instead of walking on the flat ground, the posture is horizontal in the stair climbing process, the gravity of the device is adjustable, three-foot stair climbing device is stable and reliable, and the wheels have the ratchet reverse locking function and are good in safety.

Maintenance of the Rate of Stair Use over a Long-term Period Using a Stair Climbing Campaign

Abstract: OBJECTIVE This study was a long-term survey of a stair climbing campaign that made use of point-of-choice prompts aimed at achieving exemplary behavior in citizens. METHODS The campaign began in September 2007 at the Kochi Prefectural Office. We monitored office workers who climbed the stairs or used the elevator in the prefectural office building, excluding weekends, from August 2007 through February 2009. Prompts were placed on the stair risers. A total of 59 days were monitored during the observation period. A questionnaire was distributed to 250 workers to examine the influence of the prompts following completion of the observation period. RESULTS A total of 16,583 observations of the choice of workers to use the elevators or stairs were made during the observation period. The mean number of stair users was 281.0 ± 66.0 per day. Stair use increased significantly from 31.5 to 58.1% among women and from 26.3 to 62.4% among men during months 1-3 of the campaign. Stair use was maintained in more than 51% of women and 60% of men during the entire campaign period. The following response (valid records: 81) was given by 10% of the respondents regarding the use of stairs: "my use of stairs increased due to the message banners". CONCLUSIONS The stair climbing campaign was effective for increasing stair use and was maintained over a long-term period. However, most office workers thought that their increased stair use was not due to prompts placed on risers; therefore, the reason for the increased stair use remains unclear.

Tower Running-Participation, Performance Trends, and Sex Difference.

Abstract: Though there are exhaustive data about participation, performance trends, and sex differences in performance in different running disciplines and races, no study has analyzed these trends in stair climbing and tower running. The aim of the present study was therefore to investigate these trends in tower running. The data, consisting of 28,203 observations from 24,007 climbers between 2014 and 2019, were analyzed. The effects of sex and age, together with the tower characteristics (i.e., stairs and floors), were examined through a multivariable statistical model with random effects on intercept, at climber's level, accounting for repeated measurements. Men were faster than women in each age group (p 69 years), and the difference in performance stayed around 0.20 km/h, with a minimum of 0.17 at the oldest age. However, women were able to outperform men in specific situations: (i) in smaller buildings ( 69 years; (ii) in higher buildings (>2200 stairs), for age groups 69 years. In summary, men were faster than women in this specific running discipline; however, women were able to outperform men in very specific situations (i.e., specific age groups and specific numbers of stairs).
