Description

Technical Field

[0001] The present invention relates to the technical field of corridor elevators, and in particular to a corridor walking device. Background Art

[0002] As the shantytown renovation policy gradually comes to an end, the renovation of old residential communities has been proposed. Some residential buildings built in the last century do not have elevators, which brings great inconvenience to the elderly living there. Local governments have successively issued policies to install elevators in old high-rise residential buildings. However, due to restrictions such as building spacing or building height, a large number of old buildings are not suitable for elevator installation. Therefore, relay-type corridor mobility devices have become another option.

[0044] See also Figures 1 to 5 , a corridor walking device, comprising:

[0045] Transmission structure 1;

[0046] The loading platform 2 is connected to the lower end of the transmission structure 1;

[0047] The protection structure 3 is rotatably connected to the upper end of the transmission structure 1;

[0048] The protective structure 3 has two symmetrically arranged protective arms 31 . As the protective structure 3 rotates on the transmission structure 1 , the two protective arms 31 are located above the loading platform 2 . The two protective arms 31 move closer to one end away from the transmission structure 1 .

[0049] The transmission structure 1 adopts a structure known from the prior art, and its primary function is to drive the loading platform 2 forward and backward. Elderly individuals using a mobility scooter stand on the loading platform 2 (in the prior art, the loading platform 2 and transmission structure 1 are often hinged, allowing for easy folding to accommodate the narrow stairways of older buildings). The protective structure 3 of this device is pivotally mounted on the upper end of the transmission structure 1. Before use, it is positioned above the transmission structure 1. During use, it rotates and extends above the loading platform 2, with two guard arms 31 enclosing the user for protection. It should be noted that the two guard arms 31, facing away from the transmission structure 1, gradually converge, allowing them to connect with the transmission structure 1 and enclose the user standing on the loading platform 2, thereby providing protection. This improves safety for the elderly. Furthermore, the two guard arms 31 rotate with the protective structure 3 above the loading platform 2. When not in use, they remain above the transmission structure 1, saving space and improving space utilization in narrow stairways of older buildings. In addition, the two guard arms 31 are positioned above the loading platform 2 after being rotated above the transmission structure 1, which is equivalent to the guard arms 31 rotating from top to bottom from the user's side. The user can prevent the guard arms 31 from hitting the body, the bag on the body or the handheld objects.

[0050] Furthermore, the arm guard 31 includes:

[0051] Outer arc tube 311;

[0052] The inner arc-shaped rod 312 is slidably embedded in the outer arc-shaped tube 311 along the center line;

[0053] The locking member 313 is mounted on the inner arc-shaped rod 312 and contacts the outer arc-shaped tube 311;

[0054] The locking member 313 is used to lock the outer arc tube 311 and the inner arc rod 312 .

[0055] The arrangement of the outer arc tube 311 and the inner arc rod 312 can minimize the interference of the arm guard 31 to the user during use. Specifically, the user stands on the loading platform 2 and pulls the arm guard 31, which rotates out from the side of the body. The two arm guards 31 are now located in front of and behind the user; then the inner arc rod 312 slides out from the outer arc tube 311, with its end located at the side of the user, surrounding the user; and then the locking member 313 locks the inner arc bar and the outer arc tube 311. The advantage of this device is that during the process of the arm guard 31 rotating to the front and back of the user, the inner arc rod 312 will not slide out at first, which makes the user more operable. The inner arc rod 312 will not slide out and interfere with the user's operation. While waiting for the inner arc rod 312 to slide out and surround the user, the user no longer needs to make any more movements to operate the arm guard 31. The whole process is simple and efficient, and the user experience is good.

[0056] Furthermore, the protective structure 3 also includes a rotating tube 32; two guard arms 31 are respectively connected to the two ends of the rotating tube 32; a rotating mounting groove 11 is opened at the upper end of the transmission structure 1; the rotating tube 32 is rotatably installed in the rotating mounting groove 11; the two ends of the rotating mounting groove 11 are respectively opened with an arc-shaped notch 12 connecting the inside and the outside; the outer end of the arc-shaped notch 12 is lower than its inner end; the arc-shaped notch 12 fits with the outer arc-shaped tube 311.

[0057] It can be seen that during the rotation of the outer curved tube 311, the inner curved rod is located within the outer curved tube 311. Initially, the end of the outer curved tube 311 away from the rotating tube 32 is facing upward, and the inner curved rod does not slide out. As the outer curved tube 311 rotates to a horizontal position and further rotates to an angled downward position, the inner curved rod 312 automatically slides out under its own weight. It should be noted that the outer curved rod can rotate to an angled downward position because of the arc-shaped notch 12, which is an inclined channel.

[0058] Furthermore, the inner wall of the outer arc tube 311 is provided with a sliding bar 314 extending along its length; the inner arc rod 312 is provided with a sliding groove corresponding to the sliding bar 314, which slides with it; the end of the outer arc tube 311 away from the rotating tube 32 is provided with an inwardly contracting retaining ring 315; the outer wall of the inner arc rod 312 is provided with a retaining protrusion 316; the retaining protrusion 316 abuts against the retaining ring 315. The inner arc rod 312 is provided with a plurality of obliquely arranged locking square holes 317; each locking square hole 317 is installed in a set of locking members 313;

[0059] The locking member 313 includes:

[0060] The locking square column 313a is slidably mounted in the locking square hole 317;

[0061] A locking plate 313b, one end of which is connected to the locking square column 313a;

[0062] A locking spring 313c, one end of which is connected to the locking square column 313a;

[0063] A locking rubber ball 313d connected to the locking spring 313c;

[0064] The locking rubber ball 313 d abuts against the inner wall of the outer arc-shaped tube 311 ; the locking rubber ball 313 d contacts the locking plate 313 b ; and the opening of the locking square hole 317 is tilted toward the limiting ring 315 .

[0065] The centerline of the locking column 313a is tilted relative to the inner wall of the outer arc tube 311. When the outer arc tube 311 is rotated to an angled downward position, the inner arc rod 312 slides out from the outer arc tube 311 to surround and protect the user. If the user experiences an accident and the inner arc rod 312 requires support, it tends to retract into the outer arc tube 311. The locking plate 313b and the inner wall of the outer arc tube 311 jointly abut against the locking rubber ball 313d, preventing the inner arc rod 312 from retracting further into the outer arc tube 311. This achieves locking and makes unlocking simpler and more convenient. It is only necessary to manually drive the outer arc rod back to the top of the transmission structure 1. During the process of the outer arc rod rotating and resetting, the inner arc rod 312 gradually rises along with the outer arc tube 311; at this time, the locking square column 313a slides toward the bottom of the locking square hole 317 under the action of gravity, and the locking square column 313a drives the locking spring 313c and the locking rubber ball 313d back into the locking square hole 317. Naturally, the locking relationship between the inner arc rod 312 and the outer arc tube 311 is released.

[0066] Furthermore, a placement tube 13 is provided on the inner wall of both ends of the rotating placement groove 11; the two ends of the rotating tube 32 are respectively coaxially rotatably sleeved outside the two placement tubes 13; a rotating column 33 is rotatably sleeved in the placement tube 13; a torsion spring 34 is provided in the placement tube 13; the two ends of the torsion spring 34 are respectively connected to the inner wall of the rotating placement groove 11 and the end of the rotating column 33; the outer arc tube 311 is connected to the rotating tube 32; the inner arc rod 312 is connected to the end of the rotating tube 32 with an insert block 318; the rotating column 33 is provided with a locking slot 331 that fits with it on one side of the insert block 318.

[0067] A coaxial bearing is connected to the inner wall of the placement tube 13, and the inner ring of the bearing is sleeved on the rotating column 33. After use, the user resets the outer arc tube 311. As the outer arc tube 311 rotates to the top of the rotating placement groove 11, the entire outer arc tube 311 stands upright, and the end of the inner arc rod 312 slides along the outer arc tube 311 and inserts into the rotating tube 32. The insert block 318 is directly inserted into the engaging notch 331. Under the action of the torsion spring 34, the rotating column 33 maintains another angle, thereby limiting the inner arc rod from deflecting with the outer arc tube 311. , thereby restricting the inner arc rod 312 and the outer arc tube 311. When the device is not in use, the outer arc tube 311 and the inner arc rod 312 maintain this state under the action of the torsion spring 34; when the device is used, as the outer arc tube 311 rotates, the inner arc rod 312 rotates accordingly, thereby driving the rotating column 33 to rotate until the engaging slot 331 on the rotating column 33 is opened in a horizontal state, and the inner arc rod 312 can slide out of the outer arc tube 311.

[0068] Furthermore, two opposite side walls of the engaging slot 331 are inclined.

[0069] The inclined engaging slot 331 contacts the insert block 318. When in use, the outer arc tube 311 is rotated, and after the inner arc rod 312 rotates to a horizontal state, the end of the insert block 318 contacts the side wall of the engaging slot 331 and is pushed outward; thereby, the inner arc rod and the rotating column 33 are automatically disengaged.

[0070] Furthermore, it also includes a driving switch; the driving switch is installed outside the outer arc tube 311; the driving switch is electrically connected to the transmission structure 1.

[0071] The driving switch (not shown in the figure) is used to control the movement of the transmission structure 1. It is set on the outer arc tube 311 and has its unique advantages. When the user uses this device, the arm is pressed on the outer arc tube 311 for support; and the switch is set on the outer arc tube 311. The user triggers the driving switch after grabbing the outer arc rod with his arm, which can stabilize the body and is convenient to operate. Compared with the existing switch set on the transmission structure 1 (on the side of the body) which is very awkward, this will be much more natural and provide a good experience.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
