When the elevator falls, people taking the elevator in the elevator should take some danger-avoiding postures so as to ensure life safety as much as possible. Keep away dangerous posture when elevator falls includes: the back is tightly attached to the wall of the elevator, and the legs are slightly bent, so that the buffering force during falling is increased, and the damage to the body caused by the vibration of the elevator is reduced; when the handrail is arranged in the elevator, the handrail is grasped as much as possible in the falling process of the elevator, the body balance is kept, and meanwhile, the body is supported by the handrail. At present, corresponding protective facilities are rarely arranged in the elevator car, and handrails are arranged in part of the elevator car, but the improvement space is still provided.

The invention aims to provide a personnel protection device arranged in a lift car of a lifting elevator, which can provide certain buffer protection effect for elevator taking personnel and guarantee the safety of the personnel.

As shown in fig. 1, 2 and 3, the passenger guard of the elevator of the present embodiment includes a support 1, a buffer plate 2 and a handrail 3. Support 1 fixed mounting is in the car of elevator, and handrail 3 links to each other with support 1 through pivot 11, and buffer board 2 and handrail 3 link to each other, can set up a pair of handrail 3 on the support 1, and buffer board 2 spans two handrails 3, links to each other with two handrails 3. The handrails 3 can be turned in the direction of the arrows in fig. 1, so that the handrails 3 can be put away or put down, and the handrails 3 are convenient for the passengers in the elevator to grasp and provide support for the passengers. The bracket 1 may be fixed to a car side wall of the elevator or a floor of the car by a screw fastener or in a welded manner.

The bumper plate 2 is connected to the armrest 3 so that when the armrest 3 is stowed or lowered, the bumper plate 2 is also stowed or lowered along with the armrest 3. At ordinary times, the handrail 3 and the buffer board 2 are turned to be vertical and are folded, so that the occupation of the inner space of the elevator can be reduced. When emergency happens, the handrail 3 and the buffer plate 2 are put down to be in a horizontal state, so that a protection effect is provided for people in the elevator. In other embodiments, the armrest may not be provided, and the damping plate may be directly connected to the bracket 1 through a rotating shaft.

The buffer plate 2 of the present embodiment is connected to the armrest 3 by the pressing plate 4 and the bolts 5. Optionally, the bottom surface of the armrest 3 of this embodiment is provided with an assembly groove 3a, the buffer plate 2 can be placed in the assembly groove 3a, the pressing plate 4 is pressed on the bottom surface of the buffer plate 2, the bolt 5 penetrates through the pressing plate 4 and the through hole in the buffer plate 2, extends into the threaded hole in the armrest 3, and the buffer plate 2 and the armrest 3 are assembled together in a threaded connection manner. In order to provide better buffer support for people taking the elevator, the width L of the buffer plate 2 is more than or equal to 0.2 meter. When the buffer plate 2 is laid down to be in a horizontal state, the height of the buffer plate 2 (the distance between the buffer plate 2 and the floor of the elevator car) can be set to be 0.6-0.7 m. The distance between the two handrails 3 can be set to 0.45-0.6 m.

The cushion panel 3 of the present embodiment has a multi-layer structure, and as shown in fig. 4, the cushion panel 2 sequentially includes a canvas layer 21, a silicone mesh layer 22, and a nylon mesh layer 23 from top to bottom. The canvas layer 21 is located at the uppermost layer of the damping plate 2, which may be broken when subjected to a large impact force, thereby providing a primary damping. The silicone layer 22 is located below the canvas layer 21 and can be elastically deformed when subjected to an impact force, thereby providing secondary cushioning. Nylon layer 23 is located the lower most layer of buffer board 2, mainly plays the effect of holding in the palm year silica gel layer 22 and canvas layer 21, and elastic deformation also can take place on nylon layer 23 simultaneously to can utilize elastic deformation to provide tertiary buffering when receiving the impact force, with the impact that brings that slows down falling to the personnel who leans on buffer board 2. In some alternative embodiments, the canvas layer 21 may have a thickness of 0.1mm and may be made of a thin canvas having an ampere number of 6 to 10. The silica gel network layer 22 can be made by warp knitting silica gel having a mass per unit area of about 250 grams per square meter. The nylon net layer 23 is knitted by nylon ropes with the diameter of 3.5mm, and the aperture of meshes is 30mm.

As a preferred embodiment of the invention, the bracket 1 is provided with the alarm device 6, when the handrail 3 and the buffer plate 2 are put down to the horizontal state and impact occurs, the switch of the alarm device 6 can be triggered, so that the alarm device 6 gives out alarm sound, the attention of people outside the elevator is facilitated, and the rescue can be carried out in time. The switch of the alarm device can adopt a collision switch and is triggered when being impacted.

The use of the invention in a personal protection arrangement for an elevator will now be described with reference to fig. 5. As shown in fig. 5, the passenger protection device is fixedly installed in the car of the elevator, and when not in use, the handrail 3 and the buffer plate 2 are both turned over to be in a vertical state, so that the space in the car is reduced. When the elevator falls, the handrail 3 and the buffer board 2 are turned to the horizontal state, and the buffer board 2 and the support 1 are perpendicular to each other at the moment. Take advantage of terraced personnel both hands and tightly hold handrail 3, the elevator wall is hugged closely at the back to half squatting gesture buttock leans on buffer board 2, utilizes the mode of multilayer buffering, and buffer board 2 can provide certain cushion effect for taking advantage of terraced personnel when the elevator tenesmus, in order to reduce the impact of falling and bringing, alleviates the injury of assaulting for taking advantage of terraced personnel and bringing.

The invention also provides an elevator, which comprises an elevator car 10 and a personnel protecting device arranged in the elevator car, as shown in fig. 5. The technical effect brought by the elevator provided by the embodiment is the same as or similar to the technical effect of the personnel protection device in the embodiment, and the embodiment of the personnel protection device is specifically referred to.

Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that the embodiments of the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the present invention, and the present invention is also intended to cover such modifications or equivalents.
