Description

Technical Field

[0001] This application relates to the field of walking aids, and in particular to a compact walking aid. Background Technology

[0002] Wheeled walking trolleys are an important assistive device widely used by elderly people with mobility difficulties, patients with lower limb dysfunction, and people recovering from surgery, providing them with walking support, carrying items, and short rest.

[0003] In existing related technologies, wheeled walking aids are designed with folding and fixed structures. Folding wheeled walking aids include a main frame, folding components, and a seat cushion component. Users can fold and unfold the folding wheeled walking aids using the folding components.

[0004] Regarding the aforementioned technologies, although folding wheeled walking aids can be folded, they require specific actions to fold and unfold, such as bending over or squatting. However, most users are people with mobility impairments, making it difficult for them to fold, unfold, and use the stroller themselves, thus making it inconvenient for them to use. Summary of the Invention

[0005] To address the inconvenience of using wheeled walking trolleys, this application provides a compact walking trolley.

[0006] The present application provides a compact walking cart with the following technical solution:

[0007] A compact walking stroller includes two opposing main supports, connectors, a folding assembly, and a seat assembly;

[0008] The main support includes a first support, a second support, and a support rod;

[0009] The first bracket is slidably fitted with a connector, the connector is provided with a support protrusion, one end of the support rod is rotatably connected to the connector, and the other end of the support rod is rotatably connected to the second bracket;

[0010] When the connector slides along the first bracket, the compact walking trolley switches between a folded state and an unfolded state.

[0011] When the compact walking trolley is in the folded state, the support protrusion detaches from the top of the support rod;

[0012] When the folded walking trolley is in the unfolded state, the support protrusion presses downward against the top of the support rod;

[0013] The folding assembly includes a first folding rod and a second folding rod. One end of the first folding rod and the second folding rod are respectively rotatably connected to a connector and a first bracket of one of the main frames. The other end of the first folding rod and the second folding rod are respectively rotatably connected to a connector and a first bracket of another main frame. The first folding rod and the second folding rod are rotatably connected.

[0014] The seat cushion assembly is mounted on top of the connector and is used to provide a seat for the user.

[0015] By adopting the above technical solution, when the connector slides along the first bracket, the walking aid can switch between folded and unfolded states, achieving a compact folding mechanism. The up-and-down sliding of the connector causes the support rod to rotate around the first bracket, causing the second bracket to move closer to or away from the first bracket, completing the folding or unfolding of the first and second brackets of the main frame. The up-and-down sliding of the connector causes the first and second folding rods to rotate crosswise, causing the first brackets of the two main frames to fold or unfold synchronously. When the compactly folded walking aid is in the folded state, the support protrusion disengages from the support rod. When the compactly folded walking aid is in the unfolded state, the support protrusion presses down against the top of the support rod, ensuring the stability of the seat assembly. By sliding the connector along the first bracket, a compactly folded walking aid is achieved, making the walking aid easy for the user to use.

[0016] Optionally, the seat cushion assembly is detachably mounted to the connector.

[0017] By adopting the above technical solution, it is easy to replace the seat cushion components of different sizes or functions of the compact walking stroller, which can be adapted to users with special body types and expand the purpose of rehabilitation training. At the same time, it can be disassembled separately for easy cleaning.

[0018] Optionally, the connector is provided with a support mounting hole;

[0019] The seat cushion assembly includes a seat cushion support rod and a seat cushion plate. The seat cushion support rod is detachably inserted into a support mounting hole, and the seat cushion plate is mounted on the seat cushion support rod.

[0020] By adopting the above technical solution, the connector is provided with a support mounting hole. The seat support rod is detachably inserted into the support mounting hole, and the seat support rod can be quickly installed and removed without tools.

[0021] Optionally, there are two seat support rods, which are respectively inserted into the support mounting holes of the connectors of the two main brackets. The seat plate is located between the two seat support rods and can be folded.

[0022] By adopting the above technical solution, two seat support rods are provided. Each of the two seat support rods is inserted into the support mounting holes of the connectors of the two main brackets. The seat plate is located between the two seat support rods, ensuring the stability of the seat plate when the folded walking aid is in the unfolded state. The seat plate can be folded. When the folded walking aid is folded or unfolded, the seat support rods can move with the connectors by lifting or unfolding the seat plate, facilitating the switching between the folded and unfolded states of the walking aid.

[0023] Optionally, the second bracket is provided with a support block, the support block having a support groove, and the seat cushion support rod is detachably engaged with the support groove.

[0024] By adopting the above technical solution, the second bracket is provided with a support block, the support block has a support groove, and the seat support rod is detachably engaged with the support groove, so that the compact walking aid can switch between the folded state and the unfolded state. When the walking aid is in the unfolded state, the seat support rod is engaged with the support groove, thereby improving the stability of the seat.

[0025] Optionally, the first bracket is provided with a handle bar, which is height-adjustably mounted on the first bracket.

[0026] By adopting the above technical solution and adjusting the height of the handle bar of the first bracket, the gripping needs of users of different heights can be met.

[0028] By adopting the above technical solution, the handle bar slides into the first bracket. The handle bar is provided with several height adjustment holes. The first bracket is threaded with a locking knob, which is inserted into the height adjustment holes. When it is necessary to adjust the height of the handle bar, loosen the locking knob, adjust the height of the handle bar, and finally tighten the locking knob into the height adjustment hole of the handle bar to fix the height of the handle bar, so as to facilitate the user to adjust the height and thus suit users of different heights.

[0029] Optionally, the bottom end of the first bracket is detachably provided with a first roller, and the bottom end of the second bracket is detachably provided with a second roller.

[0030] By adopting the above technical solution, with a first roller detachably mounted at the bottom of the first bracket and a second roller detachably mounted at the bottom of the second bracket, the rollers of the walking aid can be replaced according to different scenarios, and the rollers can facilitate the user to move the walking aid.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The connecting piece slides along the first support frame to switch between folded and unfolded states of the walking aid. The up-and-down sliding of the connecting piece causes the support rod to rotate around the first support frame, causing the second support frame to move closer to or away from the first support frame, thus completing the folding or unfolding of the first and second supports of the main frame. At the same time, the up-and-down sliding of the connecting piece causes the first and second folding rods to rotate crosswise, causing the first supports of the two main supports to fold or unfold synchronously. The folding or unfolding action of the seat cushion causes the connecting piece to slide, synchronously driving the main frame, support rod and folding assembly to move together, thereby realizing the single-action synchronous folding or unfolding of the walking aid, which is convenient for users to use.

[0033] 2. The foldable seat assembly can be folded and unfolded along with the walking stroller, making it easy to fold or unfold the walking stroller simultaneously. At the same time, the detachable seat assembly makes it easy to replace or clean the seat assembly.

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0043] This application discloses a compact walking cart. (Refer to...) Figure 1 The compact walking stroller includes two opposing main supports 1, a connector 2, a folding assembly 3, and a seat assembly 4.

[0044] Reference Figure 2 and Figure 3 The main support 1 includes a first support 11, a second support 12 and a support rod 13. The first support 11 is slidably fitted with a connector 2, and the connector 2 is provided with a support protrusion 21. One end of the support rod 13 is rotatably connected to the connector 2, and the other end of the support rod 13 is rotatably connected to the second support 12.

[0045] When the connector 2 slides along the first bracket 11, the compact walking trolley switches between a folded state and an unfolded state.

[0046] When the compact walking trolley is in the folded state, the support protrusion 21 detaches from the top of the support rod 13.

[0047] When the compact walking trolley is in the unfolded state, the support protrusion 21 presses down against the top of the support rod 13 so as to support the connector 2 through the support rod 13.

[0048] Reference Figure 3 The folding assembly 3 includes a first folding rod 31 and a second folding rod 32. One end of the first folding rod 31 and the second folding rod 32 are respectively rotatably connected to a connector 2 of one of the main frames and a first bracket 11. The connection between the first folding rod 31 and the connector 2 is located at the top of the connection between the second folding rod 32 and the first bracket 11.

[0049] Reference Figure 3The other ends of the first folding rod 31 and the second folding rod 32 are respectively rotatably connected to the first bracket 11 and the connector 2 of another main frame, and the connection between the first folding rod 31 and the first bracket 11 is located at the bottom of the connection between the second folding rod 32 and the connector 2. Furthermore, the middle part of the first folding rod 31 is rotatably connected to the middle part of the second folding rod 32, so that the first folding rod 31 and the second folding rod 32 are arranged in an "X" shape.

[0050] When the folded walking aid needs to be folded, the connector 2 slides upward along the first bracket 11, and the second bracket 12 moves closer to the first bracket 11 under the action of the support rod 13. At the same time, the first brackets 11 move closer to each other through the rotation of the first folding rod 31 and the second folding rod 32. When the folded walking aid is fully folded, the support protrusion 21 gradually detaches from the top of the support rod 13.

[0051] When the folded walking trolley needs to be unfolded, the connector 2 slides downward along the first bracket 11, and the support protrusion 21 presses against the top of the support rod 13. The second bracket 12 moves away from the first bracket 11 under the action of the support rod 13. At the same time, the first brackets 11 move away from each other through the rotation of the first folding rod 31 and the second folding rod 32, realizing one-click folding of the walking trolley. When the walking trolley is needed, it is easy to unfold and use it with one click. When the walking trolley is not needed, it is easy to fold and store it.

[0052] Reference Figure 4 Specifically, connector 2 has a support mounting hole 201. The seat assembly 4 includes two seat support rods 41 and a seat plate 42. The two seat support rods 41 are respectively inserted into the support mounting holes 201 of connector 2 of the two main brackets 1, so that the seat plate 42 can be disassembled and installed without tools, and at the same time, it is convenient to clean the main bracket 1 and the seat plate 42 of the walking aid. The seat plate 42 is located between the two seat support rods 41, and the two sides of the seat plate 42 are respectively fixedly connected to the two seat support rods 41. The seat plate 42 can be folded so that the two seat support rods 41 can be moved closer to each other by the seat plate 42.

[0053] When the folded walking trolley needs to be folded into a compact state, the folding seat 42 is lifted upwards, and the seat support rod 41 drives the connector to slide upwards along the first bracket 11, which simultaneously folds the first bracket 11 and the second bracket 12 of the main bracket 1. Similarly, when the folded walking trolley needs to be unfolded, the first bracket 11 and the second bracket 12 of the main bracket 1 can be unfolded simultaneously, so that the user can easily fold or unfold the walking trolley with one click.

[0054] like Figure 5 and Figure 6The second support 12 is equipped with a support block 14, which has a support groove 141. The seat support rod 41 is detachably engaged with the support groove 141. When the folded walking aid is in the unfolded state, the seat support rod 41 engages with the support groove 141 to provide support for the seat plate 42. Furthermore, the seat support rod 41 can rotate within the support groove 141, allowing the folded walking aid to switch between folded and unfolded states. The seat plate 42 can be a seat retractable fabric, allowing the seat retractable fabric to be retracted or unfolded by rotating the seat support rod 41.

[0055] Reference Figure 6 The first bracket 11 is equipped with a handle rod 15, which has several height adjustment holes 151. A locking knob 152 is threaded onto the first bracket 11 and engages with the height adjustment holes 151. The handle rod 15 is slidably engaged with the first bracket 11. When the handle height needs to be adjusted, the locking knob 152 is loosened, the handle rod 15 of the first bracket 11 is slid to realign the height adjustment holes 151 with the locking knob 152, and the locking knob 152 is tightened to fix the handle height, thus making it suitable for people of different heights.

[0056] Reference Figure 6 Specifically, the bottom end of the first bracket 11 is detachably equipped with a rotatable first roller 111. The first roller 111 is a caster wheel to facilitate easier turning. The wheel frame of the first roller 111 is inserted into the interior of the first bracket 11 and is bolted to the first bracket 11. The bottom end of the second bracket 12 is detachably equipped with a rotatable second roller 121. The second roller 121 is inserted into the interior of the second bracket 12 and is bolted to the second bracket 12, allowing for easy replacement of the less suitable first roller 111 and / or second roller 121 by unscrewing the bolts.

[0057] The implementation principle of a compact walking cart according to an embodiment of this application is as follows:

[0058] When the folded stroller needs to be folded into a compact state, when the seat cushion 42 is folded upward, the connector 2 moves upward along the first bracket 11 under the drive of the seat cushion support rod 41. One end of the support rod 13 is rotatably connected to the connector 2, and the other end of the support rod 13 is rotatably connected to the second bracket 12. The second bracket 12 moves closer to the first bracket 11 under the drive of the support rod 13.

[0059] One end of the first folding rod 31 and the second folding rod 32 are respectively rotatably connected to the connector 2 and the first bracket 11 of one of the main frames. The connection between the first folding rod 31 and the connector 2 is located at the top of the connection between the second folding rod 32 and the first bracket 11. The other ends of the first folding rod 31 and the second folding rod 32 are respectively rotatably connected to the connector 2 and the first bracket 11 of another main frame. The connection between the first folding rod 31 and the first bracket 11 is located at the bottom of the connection between the second folding rod 32 and the connector 2.

[0060] The first folding rod 31 and the second folding rod 32 are arranged in an "X" shape. The middle part of the first folding rod 31 is rotatably connected to the middle part of the second folding rod 32. When the connecting piece 2 slides upward along the first bracket 11, the two first brackets 11 move closer to each other through the rotation of the middle parts of the first folding rod 31 and the second folding rod 32. When the compact walking aid is fully folded, the support protrusion 21 disengages from the top of the support rod 13, thereby realizing one-click folding of the walking aid.

[0061] When the folded walking aid needs to be unfolded, the seat 42 is unfolded downwards. The connecting piece 2 moves downwards along the first bracket 11 under the action of the seat support rod 41. The second bracket 12 moves away from the first bracket 11 under the action of the support rod 13. The two first brackets 11 are separated from each other by the rotation of the middle of the first folding rod 31 and the second folding rod 32. When the folded walking aid is fully unfolded, the support protrusion 21 presses down against the top of the support rod 13, thereby realizing the one-button unfolding of the walking aid.

[0062] Therefore, this application uses a support rod 13 that is rotatably connected to the connector 2 at one end and to the second bracket 12 at the other end. The first folding rod 31 and the second folding rod 32 are respectively rotatably connected to the connector 2 and the other end of the first bracket 11. The first folding rod 31 and the second folding rod 32 are arranged in an "X" shape. The folding or unfolding action of the seat plate 42 drives the connector 2 to slide, which simultaneously drives the main bracket 1, the support rod 13 and the folding assembly 3 to move together, thereby realizing the single-action synchronous folding or unfolding of the walking aid stroller, which is convenient for users to use.

[0063] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
