Description

Technical Field

[0001] The present invention relates to the technical field of public facilities, and particularly relates to a handrail structure for public transportation vehicles. Background Art

[0002] With the development of cities in China, urban rail transit has gradually become the preferred mode of travel for passengers due to its energy conservation, environmental protection, high efficiency, and speed. However, due to the large population in China, overcrowding is very serious when taking buses, subways, or light rails, especially during peak commuting hours or holidays. Therefore, horizontal and vertical handrails are installed on buses, subways, or light rails, and hanging ring handrails are installed on the horizontal handrails. The hanging ring handrails play a very important role in solving the balance and safety problems of passengers. However, the hanging ring handrails have some disadvantages:

[0003] (1) The hanging ring handrails are fixed on the horizontal handrails and cannot be adjusted. Generally, they are 1.6M - 1.8M above the ground. Due to the differences in the heights of passengers, the hanging ring handrails cannot be conveniently used by some passengers.

[0004] (2) Most of the hanging ring handrails adopt a rope suspension structure, with a single structural form and a narrow practical range. And due to their swinging characteristics, when the urban rail transit suddenly accelerates, decelerates, or stops at stations, it usually causes many potential safety hazards such as passengers colliding with each other. Summary of the Invention

[0005] The present invention provides a handrail structure for public transportation vehicles, which solves the problems of the existing hanging ring handrails having a single structure, a fixed installation height, and a small practical range.

[0006] The present invention can be realized through the following technical solutions:

[0007] A handrail structure for public transportation vehicles includes a housing that cooperates with the horizontal handrail inside the public transportation vehicle. An inner cavity that cooperates with a grip and a transmission mechanism is provided inside the housing. A first passage for the grip to pass through is provided at its bottom. The grip is connected to the transmission mechanism. The transmission mechanism is used to lock the grip inside the housing or release the lock of the grip inside the housing, and to control the switching of the grip between a fixed mode and a suspended mode.

[0008] Further, the transmission mechanism includes a switch button and a switching button provided on the surface of the housing. The switch button is used to control locking the grip inside the housing or releasing the lock of the grip inside the housing. The switching button is used to control the switching of the grip between a fixed mode and a suspended mode.

[0009] Further, the transmission mechanism includes a buckle that cooperates with the grip. The buckle is L-shaped, with its short side cooperating with the step on the upper part of the grip, and the free end of its long side being perpendicularly connected to one end of the first link. The other end of the first link extends along a second channel that matches it inside the housing until outside the housing and is connected to the switch button. A plurality of springs are provided on the side of the long side close to the inner cavity.

[0010] The lower part of the grip passes through the opening on the clamping plate and extends into the first channel. One side of the clamping plate is connected to one end of the second link. The other end of the second link extends along a third channel that matches it inside the housing until outside the housing and is connected to the switching button. A plurality of springs are provided on the side opposite to one side of the clamping plate.

[0011] The top surface of the grip is connected to the top of the inner cavity through a pull strap.

[0012] Further, the first link and the switch button, and the second link and the switching button are both of an integral structure.

[0013] Further, the top surface of the grip is provided with a plurality of springs and a groove that cooperates with the first link.

[0014] Further, the grip is generally of an L-shaped structure, with its short side cooperating with the short side of the buckle. The lower part of the grip is provided with an opening for the passenger's hand to pass through.

[0015] The beneficial technical effects of the present invention are as follows:

[0016] During use, the grip can be popped out simply by pressing the switch button on the cross bar. At the same time, the conversion between the fixed mode and the suspension mode can be achieved by pressing the switching button. This can not only meet the needs of more passengers with different height differences, but also, in the fixed mode structure, reduce the unnecessary losses caused by the shaking of passengers during the acceleration, deceleration or stop of urban rail transit. At the same time, the suspension mode can also meet the needs of passengers who are used to using suspension rings. When not in use, the grip can be pushed up into the housing, making passengers feel more comfortable, convenient, safe and saving public space. At the same time, for the housing structure form of the present invention, during maintenance and repair, only the upper and lower parts need to be opened, which is very convenient, and has the characteristics of low cost and cost saving. In addition, the present invention has a simple structure, is easy to use, has a low cost, and has a broad market application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will describe in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0025] As Figure 1 and 2 shown, the present invention provides a handrail structure for public transportation vehicles, including a housing 2 that cooperates with a cross tie rod 1 inside the public transportation vehicle. An inner cavity that cooperates with a grip 3 and a transmission mechanism is provided inside the housing 2. A first passage for the grip 3 to pass through is provided at its bottom. The grip 3 is connected to the transmission mechanism. The transmission mechanism is used to lock the grip 3 inside the housing 1 or release the lock of the grip 3 inside the housing 1, and to control the switching of the grip 3 between the fixed mode and the suspension mode. In this way, with the help of the transmission mechanism, the grip 3 can be locked inside the housing 1, reducing the occupied space and improving the utilization rate of the internal space of the public transportation vehicle. At the same time, the grip 3 can have two usage modes, the fixed mode and the suspension mode, which can meet the usage requirements of more passengers and have a wider range of practical applications.

[0026] As Figure 3 and 4As shown, the transmission mechanism includes a buckle 4 that cooperates with the grip 3. The buckle 4 is L-shaped, with its short side cooperating with the step on the upper part of the grip 3, and the free end of its long side being perpendicularly connected to one end of the first link 5. The other end of the first link 5 extends along the second channel that cooperates with it inside the housing 2 until outside the housing 2. A plurality of springs 6 are provided on the side of the long side close to the inner cavity. The lower part of the grip 3 passes through the opening on the clamping plate 7 and extends into the first channel. One side of the clamping plate 7 is connected to one end of the second link 8. The other end of the second link 8 extends along the third channel that cooperates with it inside the housing 1 until outside the housing 1. A plurality of springs 6 are provided on the side opposite to one side of the clamping plate 7. The top surface of the grip 3 is connected to the top of the inner cavity through a pull strap 9. In this way, the first link 5 exposed outside the housing 1 together with the springs on the buckle 4 can act as a switch button, playing the role of controlling the locking of the grip 3 inside the housing 1 or unlocking the grip 3 inside the housing 1. That is, when the first link 5 is pressed, the corresponding spring is compressed, and at the same time, the short side of the buckle 4 is disengaged from the step of the grip 3. The grip 3 moves downward until the step on it catches on the clamping plate 7, and the lower part of the grip 3 is exposed outside the housing, forming a fixed-mode grip 3, as Figure 5 shown; when it is necessary to switch to the suspension mode, as Figure 6 shown, the second link 8 exposed outside the housing 2 and the corresponding springs act as a switching button, playing the role of switching the grip 3 between the fixed mode and the suspension mode. That is, when the second link 8 is pressed, the corresponding spring is compressed, and at the same time, the clamping plate 7 and the step of the grip 3 are disengaged. The grip 3 is completely exposed outside the housing 2 and is suspended on the housing 2 by means of the pull strap 9, forming the suspension mode.

[0027] When it is necessary to change back to the fixed mode, only need to press the second link 8 again to move the grip 3 upward into the housing 2. At this time, an indicating line can be set on the grip 3. As long as the indicating line enters the housing 2, the second link 8 can be released, and the step on the grip 3 can catch on the clamping plate 7 to form the fixed mode, or continue to move the grip 3 upward until it touches the buckle 4, then release the second link 8, and then the grip 3 will fall until the step on it catches on the clamping plate 7, which can also form the fixed mode.

[0028] When locking is achieved, the first link 5 and the second link 8 need to be pressed simultaneously until the top surface of the grip 3 touches the top of the inner cavity, and then the first link 5 and the second link 8 are released. At this time, the grip 3 will fall until the step on it catches on the buckle 4 to complete the locking. In order to change the rigid contact between the grip 3 and the inner cavity into a flexible contact, a plurality of springs 6 can also be provided on the top surface of the grip 3 to buffer the collision. At the same time, when unlocking, the grip 3 can be further pushed downward.

[0029] The grip 3 can be integrally designed into an L-shaped structure, the short side of which cooperates with the short side of the buckle 4. An opening for the passenger's hand to pass through is provided at the lower part of the grip 3, and a groove for cooperating with the first link 5 is provided on its top surface. Together with the second channel, it plays a role in supporting and guiding the first link 5. Similarly, the third channel for cooperating with the second link 8 also has this function.

[0030] In addition, the switch button and the toggle button can be separately provided, as long as they are respectively connected to the other ends of the first link 5 and the second link 8. This can increase the diversity and aesthetics of the buttons. The switch button and the toggle button can also adopt a button structure in the form of a press-and-lock similar to that of a ballpoint pen, so as to make the conversion operation between the fixed mode and the suspension mode more convenient. The housing 2 can also be provided with upper and lower parts, which cooperate with the cross bar 1 and can be fixed to the cross bar 1 by bolts, facilitating disassembly. After disassembly, the internal transmission mechanism can be seen, which is convenient for maintenance.

[0031] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples. Without departing from the principle and essence of the present invention, various changes or modifications can be made to these embodiments. Therefore, the protection scope of the present invention is defined by the appended claims.
