[0025] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.
[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A trolley with easily foldable armrests includes a support frame 1, a seat cushion 2, and an armrest mechanism 3. The support frame 1 includes at least a pair of support legs 11 with casters 12 connected to the bottom and a support rod 13 movably connected to the top of the support legs 11 and extending upward. A push handle 5 is sleeved on the top of the support rod 13. The push handle 5 extends outward in a direction perpendicular to the support rod 13. The surface of the push handle 5 is provided with anti-slip texture. The seat cushion 2 is located between the two support legs 11.
[0027] The handrail mechanism 3 includes the following structure: two handrail sleeves 31, which are respectively sleeved on the surfaces of two support rods 13; a hinge groove 311 is provided on one side of the handrail sleeve 31; a limiting block 312 runs horizontally between opposite sides of the hinge groove 311; one end of the limiting block 312 extends through the outside of the handrail sleeve 31; the limiting block 312 is provided with an unlocking groove 313 located in the hinge groove 311; a handrail component 32, one end of which is hinged to the hinge groove 311; a limiting groove 321 matching the limiting block 312 on one side of the handrail component 32; and a locking pin 33, which passes through the handrail sleeve 31 and the support rod 13 in sequence; and several locking holes 14 matching the locking pin 33 are passed through the surface of the support rod 13.
[0028] This utility model provides a handcart with an easily foldable handle and adjustable handle height, mainly for use by people with mobility impairments. In this handcart, the support frame 1 provides support during use and secures components such as the seat cushion 2, armrest mechanism 3, and casters 12. Preferably, as one of the better embodiments, the bottom of the support frame 1 has four support legs 11, and two support rods 13 are located at the top of the rearmost support leg 11 and nested within it, providing support for the handcart. Providing stable support, the support leg 11 on the front side is hinged to the armrest 32, which facilitates folding in the front and back directions. During the use of the trolley, the user with mobility impairment sits on the seat 2, and family members or caregivers can push the trolley through the push handle 5, making the trolley function similar to a wheelchair. In addition, the user with mobility impairment can hold onto the push handle 5 and use the support provided by the trolley to assist in walking. The trolley is moved by the casters 12 at the bottom, allowing the user to perform necessary daily activities through the trolley.
[0029] This invention enables height adjustment of the push handle 5. The armrest sleeve 31 is fixedly connected to the support frame 1. When the locking pin 33 passes through the locking hole 14 into the support rod 13, the locking pin 33 will fix the armrest sleeve 31 to the support rod 13, thus fixing the height of the push handle 5 at the top of the support rod 13. When the height of the push handle 5 needs to be adjusted, the user only needs to pull out the locking pin 33 until it is disengaged from the locking hole 14. The support rod 13 can then reciprocate along the armrest sleeve 31 in the vertical direction, thereby adjusting the height of the push handle 5. The user can adjust the height of the push handle 5 to match their own height, improving the user's comfort during the process of pushing or assisting walking using the push handle 5.
[0030] With the above structure, it should be further explained that a button groove 314 is provided on one side of the armrest sleeve 31, and a button shaft 315 runs horizontally between the opposite sides of the button groove 314. A first unlock button 34 is provided in the button groove 314 and is movably connected to the button shaft 315. The surface of the first unlock button 34 is provided with anti-slip texture, and a first spring 341 is provided on one side of the first unlock button 34 and abuts against the bottom of the button groove 314. One end of the locking pin 33 passes through the bottom of the button groove 314 and is fixedly connected to the first unlock button 34. The locking pin 33 and the first spring 341 are respectively located on both sides of the button shaft 315.
[0031] Based on the above structure, when the trolley is in the reset state, the first spring 341 causes one end of the first unlock button 34 to protrude and the other end with the locking pin 33 to tilt downwards into the button groove 314, so that the locking pin 33 passes through the locking hole 14, thereby locking the handle sleeve 31 and the support rod 13 through the locking pin 33. At this time, the support rod 13 cannot move in the vertical direction, and the push handle is in a locked state. When the user presses the end of the first unlock button 34 with the first spring 341 and squeezes the first spring 341, the first unlock button 34 will move around the button shaft 315. The first unlock button 34 is not a pivot button. It has a locking pin 33 with one end protruding. The locking pin 33 will leave the locking hole 14, so that the push handle 5 is in the unlocked state. At this time, the support rod 13 can move back and forth in the vertical direction and adjust the height of the push handle 5. When the height of the push handle 5 is adjusted to a suitable position, the first unlock button 34 is released. The first spring 341 releases elastic potential energy and moves the locking pin 33 toward the support rod 13. At the same time, the push-pull arm sleeve 31 moves up or down slightly until the locking pin 33 enters the nearest locking hole 14, so that the push handle 5 is locked again.
[0032] The handrail component 32 of this utility model can be folded for storage. The handrail component 32 is hinged to the handrail sleeve 31, so that the handrail component 32 can be changed from a horizontal orientation to a vertical orientation by folding downwards. When the handrail component 32 is in a horizontal orientation, in order to provide support for the user's hands during use, the limiting block 312 will be embedded in the limiting groove 321 to lock the handrail component 32, thus preventing the handrail component 32 from folding downwards. When it is necessary to fold the handrail component 32, the user can pull the limiting block 312 until the unlocking groove 313 matches the limiting groove 321. At this time, the handrail component is not locked by the limiting block 312 and can be folded downwards. By folding the handrail component 32 downwards, the space occupied by the handrail component 32 on the front of the trolley can be reduced. When it is needed, the handrail component 32 can be swung to a horizontal orientation and locked by the limiting block 312 to support the user's hands.
[0033] Reference Figure 1 , Figure 3 and Figure 5 The support leg 11 is hinged to the armrest sleeve 31, which allows the support leg 11 on the front wheel side to move back and forth through the hinge, making it easy to fold or unfold the handcart.
[0034] With the above structure, it should be further explained that the end of the limiting block 312 located outside the armrest sleeve 31 is provided with a second unlocking button 316, and the limiting block 312 is covered with a second spring 317. The two ends of the second spring 317 abut against the second unlocking button 316 and the armrest sleeve 31, respectively. A hinge shaft 318 runs horizontally between the opposite sides in the hinge groove 311. The bottom of the armrest component 32 is provided with a hinge end 322 that matches the hinge groove 311. The hinge end 322 passes through a shaft hole 323 that matches the hinge shaft 318. The hinge end 322 is located in the hinge groove 311 and the hinge shaft 318 passes through the shaft hole 323.
[0035] Based on the above structure, the armrest 32 and the armrest sleeve 31 are hinged to each other through the hinge groove 311, hinge end 322, hinge shaft 318 and other structures. The armrest 32 can swing based on the hinge shaft 318 as the axis, so that the armrest 32 can swing and fold from the horizontal front of the trolley to the vertical downward, so that the armrest 32 is in a downward folded state and the space occupied by the armrest 32 on the front of the trolley is reduced. The user can sit on the seat cushion 2 of the trolley more easily and improve the convenience during use.
[0036] Furthermore, when the armrest 32 is horizontal, the limiting block 312 will be inserted into the limiting groove 321, preventing the armrest 32 from swinging around the hinge shaft 318. At this time, the user can press the second unlocking button 316 to move the limiting block 312 until the unlocking groove 313 matches the limiting groove 321. At this time, the limiting block 312 and the limiting groove 321 are disengaged, and the armrest 32 can swing to the folded state based on the hinge shaft 318. When the user needs to use the armrest 32, he can directly swing the armrest 32 to the horizontal position. The second spring 317 will release elastic potential energy and cause the limiting block 312 to automatically insert into the limiting groove 321, preventing the armrest 32 from swinging. Thus, the armrest 32 can withstand the pressure of the user's hand during use without swinging.
[0037] As one of the preferred embodiments of this utility model, refer to Figure 1 A backrest cushion 4 is provided between the two support rods 13. When the user sits on the trolley, he / she can lean his / her back against the backrest cushion 4 to improve comfort. The two opposite ends of the backrest cushion 4 are fixedly connected to the two armrest pieces 32 respectively. Based on this structure, the backrest cushion 4 can be folded at the same time as the armrest pieces 32, so that the backrest cushion 4 is located above the seat cushion 2. When the trolley is not in use, these backrest cushions 4 will not protrude from the back of the trolley, which can reduce the space occupied by the trolley.
[0038] As one of the preferred embodiments of this utility model, refer to Figure 1 The support frame 1 has two outwardly extending foot pedals 6 on one side of its bottom. Each foot pedal 6 has a footrest 7 fitted onto its end away from the support frame 1. When the user sits on the trolley, they can place their feet on the footrest 7, allowing them to relax their legs. The footrest 7 is movably connected to the foot pedals 6; it can be folded upwards along the foot pedals 6 to a vertical position, allowing the user to place their legs between the two foot pedals 6 without obstruction. The footrest 7 can then be folded downwards to a horizontal position for use. Specifically, the design includes... The support bracket 11 at the front wheel position is used to connect to the pedal 6. In addition, the pedal 7 and the pedal 6 can also be movably connected to the support frame 1 by means of a hook. A hook that cooperates with the hook is set at the position of the support frame 1 near the caster 12. After the pedal 6 is hung on the hook, it is fixed to the surface of the support frame 1 by gravity self-locking. When the pedal 7 is not needed, the user can easily remove the pedal 6 from the support frame 1 and place it in the storage bag connected to the support frame 1, which is very convenient.
[0039] As one of the preferred embodiments of this utility model, the support frame 11 is composed of no less than two nested segments connected by a connecting locking member set at the nested overlapping position. Furthermore, the two nested segments constituting the support frame 11 are fixed at the nested overlapping position by means of methods such as threaded knobs, cam buckles, and clamps. With this quick-release structure, users can quickly fold and disassemble the trolley when it is not needed, making it easier to store and preserve.
[0040] In summary, this utility model provides a handcart with an easily foldable handle and an adjustable push handle 5 height. During use, pressing the first unlock button 34 unlocks the push handle 5, then adjusting the height of the push handle 5 and locking it by engaging the locking pin 33 with the locking hole 14.
