[0036] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
[0037] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.
[0038] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.
[0039] In order to solve the problem of lower limb inconvenience in the existing technology, some situations require human intervention to assist in carrying the lower limbs, such as Figure 1 As shown, this embodiment provides a displacement assist device. The main body of the displacement assist device is a pedal 10. In this embodiment, the pedal 10 is a circular plate made of PVC with a certain thickness. The diameter of the pedal 10 is between 30cm and 40cm. In other embodiments, the pedal 10 can also be designed as a square or trapezoidal plate as needed. The front center of the pedal 10 is a soft mat 11. The soft mat 11 is preferably made of foam sponge. The foam sponge is covered with fabric, making the soft mat 11 relatively soft and wear-resistant, making it more comfortable for the user to step on.
[0040] An elastic band 13 is provided on the left and right sides of the front of the pedal 10. The first end of the elastic band 13 is connected to the pedal 10, and the second end of the elastic band 13 is a Velcro 131. One Velcro 131 is looped wool, and the other Velcro 131 is bristle. When a user steps on the soft mat 11, the Velcro 131 at the ends of the two elastic bands 13 adhere to each other, securing the user's foot and preventing the pedal 10 from easily falling off. In other embodiments, the ends of both elastic bands 13 can be provided with either looped wool Velcro 131 or bristle Velcro 131, and the other of the looped wool Velcro 131 or bristle Velcro 131 can be provided in the middle of the elastic band 13. In this way, the looped wool Velcro 131 or bristle Velcro 131 can be attached to the looped wool Velcro 131 or bristle Velcro 131 of the other elastic band 13, so that the elastic band 13 is wrapped around the user's ankle.
[0041] A socket 12 is further provided on the front side of the pedal 10 , and the socket 12 is used to cooperate with the insertion rod 20 described below.
[0042] like Figure 2 As shown, the bottom surface of the pedal 10 has two annular raised structures 14 arranged coaxially with the main body of the pedal 10, and each raised structure 14 is provided with 8 grooves, which are mostly semi-spherical grooves, and a universal steel ball 15 is arranged in each groove. There is a radial banner between the two raised structures 14, which is a reinforcing rib 16. The two ends of the reinforcing rib 16 are respectively connected to the two raised structures 14, and the reinforcing rib 16 can ensure the strength of the pedal 10. It should be noted that most of the universal steel balls 15 are located in the grooves. When the displacement assist device is placed on the ground, the universal steel balls 15 contact the ground. When the pedal 10 is picked up, the universal steel balls 15 will not fall off from the grooves. The advantage of using universal steel balls 15 is that the overall thickness of the displacement assist device can be kept low. In other embodiments, the universal steel balls 15 can also be replaced with universal rollers or other universal supporting moving parts.
[0043] like Figure 3 As shown, the soft mat 11 protrudes from the pedal 10 to form an annular step. Therefore, the soft mat 11 has a certain thickness, has a stronger ability to cushion deformation, and fits better with the sole of the foot. In addition, the raised structure 14 can create a relatively clear gap between the edge of the pedal 10 and the ground, making it easier to pick up the pedal 10.
[0044] In some embodiments, as Figure 4 As shown, in order to facilitate the temporary positioning of the pedal 10, the pedal 10 can be temporarily positioned with an insertion rod 20 to avoid or reduce unintended movement of the pedal 10. Specifically, the pedal 10 is provided with a socket 12, into which an insertion rod 20 can be inserted. The insertion rod 20 is a metal rod with a certain weight. The lower end of the insertion rod 20 is a rubber pad 23. The insertion rod 20 uses its own weight to press the rubber pad 23 against the ground, thereby generating a braking force, restricting the movement of the pedal 10, and thus achieving a certain braking effect.
[0045] In other embodiments, to reduce the overall weight of the rod 20, in this embodiment, the rod 20 is a hard plastic rod. A spring pin assembly is provided on the inner wall of the socket 12. The outer surface of the rod 20, near its lower end, has a socket 21. The structure of the socket 21 matches the plug structure of the spring pin assembly. The lower end of the rod 20 has an elastic expansion section 22. The elastic expansion section 22 includes a downwardly extending elastic connection portion, the distal end of which is connected to the ground. When the rod 20 is inserted into the socket 12, the plug of the spring pin assembly inserts into the socket 21.
[0046] like Figure 5As shown, specifically, the plug of the spring pin assembly is a triangular plug with a flat bottom surface, and the socket 21 is a socket 21 with a circumferential extension along the outer annular surface of the plug rod 20 and a triangular cross-section. The inner wall of the socket 12 is provided with a pin hole 121, and the inner wall of the pin hole 121 is provided with a first anti-slip protrusion 123. A triangular head pin body 122 is installed in the pin hole 121. The outer annular surface of the triangular head pin body 122 has a second anti-slip protrusion 124 that cooperates with the first anti-slip protrusion 123 near the tail. The first anti-slip protrusion 123 cooperates with the second anti-slip protrusion 124 to prevent the triangular head pin body 122 from falling out. A first spring 125 is contained in the pin hole 121. The first end of the first spring 125 abuts the bottom wall of the pin hole 121, and the second end of the first spring 125 abuts the tail end of the triangular head pin body 122. The triangular head pin body 122 is in a compressed state. A cylindrical tube body 221 is fixedly installed at the lower end of the insertion rod 20, and the lower end of the tube body 221 is bent inward to form an anti-slip structure. A baffle 222 is movably provided in the tube body 221, and the lower end face of the baffle 222 has a columnar body, which extends out of the tube body 221 from the lower end of the tube body 221. The end of the columnar body is connected to the rubber pad 23. A second spring 223 is also provided in the tube body 221, and the first end of the second spring 223 abuts the baffle 222, and the second end of the second spring 223 abuts the lower end of the insertion rod 20.
[0047] When in use, insert the insertion rod 20 into the socket 12 and press it down until the rubber pad 23 touches the ground. Then, press the insertion rod 20 further downward, the second spring 223 is compressed, and the triangular head pin body 122 enters the socket 21. At this time, the insertion rod 20 is released, and the second spring 223 rebounds. The insertion rod 20 tends to move upward, so that the plane at the bottom of the triangular head pin body 122 abuts against the lower plane of the socket 21, thereby positioning the triangular head pin body 122. The second spring 223 also provides pressure on the baffle 222 and the rubber pad 23, so that the rubber pad 23 is pressed tightly against the ground to increase friction.
[0048] To remove the insertion rod 20 , simply press the insertion rod 20 downward to disengage the triangular head pin body 122 from the socket 21 , then rotate the insertion rod 20 to dislocate the socket 21 and the triangular head pin body 122 , and the insertion rod 20 can be pulled out.
[0049] In another embodiment, the jacks 12 and the rods 20 may be provided in two or more groups for better positioning. The rods 20 are 40 cm or less in height for convenient operation while sitting, and the overall length can be effectively controlled for easy storage.
[0050] This transfer assist device can be used for transferring seriously ill patients to a bed. For example, when transferring a bed, the user's feet can be placed on the footrest to prevent the user's feet from dragging on the ground and causing scratches and abrasions. It can also be used by people with lower limb disabilities to transfer positions, such as when transferring from a wheelchair to a bed.
[0051] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
