Background

The aging pressure becomes one of important factors which troubles the social development of China in the next decades, and the prior development social endowment service is written into the twelve-five program, which meets the national importance of endowment career. However, in the multi-storey houses (5-9 stories) built in the eighties and ninety years and later in China, the vertical traffic problem of the multi-storey houses becomes the most critical problem which troubles the normal life of the aged population in cities because no elevator is installed. Governments all over the country try and find good ways to solve the problem, particularly, schemes for installing box elevators in old multi-storey houses in Guangzhou, Shanghai, Beijing and other places are tried, but various problems are exposed in the process of trying, and the new schemes for solving the problem are found out that the old multi-storey houses are not ideal, so that the new schemes cannot be popularized nationwide. All parties seek and explore a more reasonable and effective mode to solve the problem of difficult climbing of the multi-storey residential buildings, and the corridor elevator is produced at the same time.

The existing corridor elevator can be divided into an exposed type and a closed type: the carrying device is wholly exposed and is called an exposed type; the combined carrying device has an integral shell, and only a pedal, a handrail, a seat board and other parts slightly protrude out of the shell after reset, so the combined carrying device is called as a closed type. Structurally, the closed-type stairway elevator has an integral enclosure, while the exposed-type stairway elevator has no integral enclosure. When the closed corridor elevator receives the instruction to carry the device to run automatically, even if someone leans on the elevator, it is safe, and when the exposed corridor elevator receives the instruction to run automatically, people in front of the carrying device can not occupy the corridor arbitrarily, otherwise, the elevator is easy to be damaged by collision, so that the elevator has potential safety hazard. For example, the invention patent with the patent number of 'CN200710071436. X' and the name of 'a corridor elevator' has the structure that: each corridor is taken as a unit, a corridor elevator capable of independently operating is respectively installed on each corridor, the corridor elevator is installed on the inner side surface of each corridor, the corridor elevator comprises a ladder frame arranged in the direction of the slope of each corridor, and an upper rail, a lower rail, a rail car, a traction device, a sealing device and a control system are arranged on the ladder frame. The relay type working mode greatly improves the working efficiency of the equipment, and the elevator adopts a sealing device, thereby reducing the failure rate and ensuring the neat and beautiful appearance.

At present, the handrail of the closed corridor elevator can refer to a handrail device for the corridor elevator, which is described in a Chinese utility model patent publication with publication number CN 201770385U; the handrail body in the scheme is fixed on the rail car and has a distance of several centimeters from the shell so as to be convenient for holding. However, the proposal has at least the following disadvantages:

1, the handrail body is fixedly arranged; when the carrying device automatically runs, the handrails are easy to be jammed by people, particularly children, to cause finger clamping damage;

2, as shown in the patent drawing with the publication number of CN201770385U, the handrail body needs to be arranged to be parallel to the housing and slightly higher than the housing, and the housing height of the corridor elevator cannot be too low and occupies much space in the corridor because the handrail needs a certain height;

3, on the basis of 2, when the user takes the corridor elevator and goes down, the lower half section of the hand-held handrail body is relatively lower and relatively inclined, and the wrist posture of the user is very uncomfortable at the moment.

Example 1:

as shown in fig. 1 to 3, the present embodiment relates to a handrail mechanism for a corridor elevator, which includes a track car frame 1 and a handrail 2 disposed on the track car frame 1. The rail car frame 1 is movably provided with a handrail connecting rod 3, and one end part of the handrail connecting rod 3 extends out of the shell and is connected with the handrail 2. The rail car frame 1 is provided with a driving part 4 for driving the handrail connecting rod 3 to move so as to enable the handrail 2 to lift relative to the shell 5.

The above technical scheme is adopted in the utility model, this technical scheme relates to a handrail mechanism on corridor elevator, and the activity is equipped with handrail connecting rod 3 on the track frame 1 among this handrail mechanism, and this activity sets up can be scheme such as slide setting, articulated setting, a tip of handrail connecting rod 3 stretch out in the 5 outsides of casing and with handrail 2 is connected. The rail car frame 1 is provided with a driving member 4, and the handrail 2 can be moved up and down with respect to the housing 5 by the handrail link 3 being movable with respect to the rail car frame 1 by the driving of the driving member 4. Based on above-mentioned scheme, this utility model realizes that handrail 2 goes up and down relative casing 5, has following effect.

1, when the corridor elevator is not operated or is in idle operation, the handrail 2 is at the lowest position. When the corridor elevator is in operation, the handrail 2 is at the highest position, and a user can hold the handrail 2 by hand. The height of the handrail 2 leaving the housing after extending out can be larger than the height of the existing handrail 2 leaving the housing, so the height of the housing can be relatively reduced, thereby reducing the space occupied by the corridor.

2, when the corridor elevator is in no-load operation, the handrail 2 can be close to the shell to operate, so that the possibility that the handrail 2 is touched by people by mistake can be reduced.

In a further embodiment, one end of the handrail connecting rod 3 is hinged to the rail car frame 1, and the driving member 4 drives the handrail connecting rod 3 to rotate along the hinged end thereof, so that the handrail 2 is lifted and lowered with respect to the housing 5. When the handrail 2 is at the lowest position, the handrail 2 is axially parallel to the upper end surface of the shell 5. The axial inclination angle of the handrail 2 at the highest position is smaller than the axial inclination angle of the handrail 2 at the lowest position. In the technical scheme, the handrail connecting rod 3 is connected to the track frame 1 in a hinged mode, and the driving part 4 drives the handrail connecting rod 3 to rotate along the hinged end of the handrail connecting rod. The advantage of using a hinged connection for lifting compared to a sliding lifting is that the axial inclination angle of the handrail 2 changes as the height position of the handrail 2 changes.

As described in the background art, in the conventional solutions, the body of the handrail 2 is substantially parallel to the housing, and in this state, the body of the handrail 2 is inclined, and when the user takes the stairway elevator down, the lower half section of the body of the handrail 2 held by the user is relatively low and inclined, and the wrist posture of the user is very uncomfortable. In this case, when the armrest 2 is at the lowest position, the armrest 2 is axially substantially parallel to the upper end surface of the housing 5. The axial inclination angle of the handrail 2 at the highest position is smaller than the axial inclination angle of the handrail 2 at the lowest position. When the corridor elevator runs, as the handrail 2 is at the highest position, the axial inclination angle of the handrail 2 is smaller, namely the lower half section of the handrail 2 is obviously lifted. When the user takes the corridor elevator and goes down, the lifting of the lower half section of the hand-held handrail 2 is obvious, so that the user can hold the handrail more conveniently and the posture is more natural.

In a specific embodiment, the output end of the driving part 4 is connected with a driving connecting rod 6, the driving part 4 is a telescopic rod, and the telescopic rod can be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod. The output end of the driving part 4 is hinged with a driving connecting rod 6. The handrail connecting rod 3 is erected on the driving connecting rod 6 through gravity. The driving part 4 drives the driving connecting rod 6 to move relative to the track frame 1, and drives the handrail connecting rod 3 and the handrail 2 connected with the handrail connecting rod to lift. Further, the driving connecting rod 6 is coaxially hinged to the armrest connecting rod 3, a limit stop 61 is arranged on the driving connecting rod 6, and the armrest connecting rod 3 can be erected on the limit stop 61 of the driving connecting rod 6. The armrest connecting rod 3 can be erected on the limit stop 61 of the driving connecting rod 6, so that the armrest connecting rod 3 and the armrest 2 can be passively lifted along with the lifting of the driving connecting rod 6. And the track frame 1 is provided with a limiting blocking piece for limiting the lifting height of the handrail connecting rod 3.

In the technical scheme, the output end of the driving part 4 is connected with the driving connecting rod 6, and the handrail connecting rod 3 is erected on the driving connecting rod 6 through gravity. That is, the driving member 4 drives the driving link 6 to move up and down, and the handrail link 3 and the handrail 2 connected thereto are simply mounted on and rest on the driving link 6. The active link 6 is passively lifted as it is lifted. Under the scheme, on one hand, the handrail connecting rod 3 and the handrail 2 connected with the handrail connecting rod can be controlled to ascend and descend through the driving part 4, and on the other hand, the handrail connecting rod 3 and the handrail 2 connected with the handrail connecting rod can also ascend and descend automatically under the action of external force. When the corridor elevator runs in no-load operation, if foreign matters are clamped between the handrail 2 and the shell, the handrail 2 can be lifted in the running process. Therefore, the structure can not cause the problem of finger clamping damage, and the safety is higher. As described above, the armrest link 3 and the armrest 2 passively move up and down as the active link 6 moves up and down in the absence of external force, but the armrest link 3 and the armrest 2 may move up and down independently of the active link 6 by external force. The limiting blocking piece 11 is arranged on the track frame 1, and the lifting height of the handrail connecting rod 3 is limited through the limiting blocking piece 11, so that the situation that the handrail 2 is forcibly pulled by external force and the handrail 2 is lifted too high can be avoided.
