Description

Technical Field

[0001] The utility model belongs to the technical field of walking assistance, and in particular relates to a walking anti-fall assistance device for the elderly. Background Art

[0002] Due to the weakening of deep muscles, the decline of balance function and the influence of bone and joint diseases, the limb ability and balance of the elderly are worse than those of young people, and they are more likely to fall while walking. Due to osteoporosis and decreased physical function, the elderly are more likely to suffer fractures and other more serious hazards after falling.

[0003] At present, for the elderly with weak limb ability and poor balance, most of them use frame-type walkers to assist walking. Such walkers are frame structures as a whole, with good stability and support for the body. When in use, the walker is moved as a whole to walk. However, since such elderly people are highly dependent on walkers for daily activities, if the function of the walker is single, it will greatly limit the convenience of daily activities for the elderly. For this reason, some walkers equipped with cushions are proposed in the prior art, which can be used for the elderly to sit down. In order to avoid the seat cushion interfering with the legs when walking, the seat cushion is generally detachable or hinged at one end and assembled on the walker. The detachable seat cushion is relatively inconvenient to carry and store, which is not conducive to sitting down and resting at any time during walking. The seat cushion with one end hinged can avoid interference with the legs by flipping it upward, and it can move with the walker, which is convenient for sitting down and resting at any time. However, since the seat cushion needs to have a certain hardness, thickness and size to meet the corresponding support strength requirements, it will cause a significant increase in the overall weight of the walker, which will make it more difficult for the elderly to move the walker. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a walking anti-fall assist device for the elderly which takes into account the use demand of sitting down and resting at any time and the overall weight of the device. While meeting the use demand of the elderly to sit down and rest at any time, the overall weight of the device is lighter, which is more conducive to the movement of the elderly, and is also convenient for the elderly to use when sitting or standing to take a bath.

[0005] The content of this utility model includes:

[0006] There are two side frames, each of which has a crossbar;

[0007] There are more than three support rods and they are all located between the two side frames. Both ends of the three or more support rods are provided with sleeves. The sleeves at one end of the three or more support rods are sleeved on the cross bar of one of the side frames, and the other ends are sleeved on the cross bar of another side frame. Among the three or more support rods, the sleeves at both ends of the support rod located on the outermost side are fixed to the cross bars of the two side frames, and the support rod is located at the front end of the two side frames. The sleeves at both ends of the remaining support rods are correspondingly slidably matched with the cross bars of the two side frames.

[0008] The limiting mechanism is used to limit the expansion distance between two adjacent support rods.

[0009] Furthermore, a limiting mechanism is provided between every two adjacent support rods, and the limiting mechanism is connected to the two support rods at the position where it is located.

[0010] Furthermore, the limiting mechanism is a rope.

[0011] Furthermore, the limiting mechanism is a telescopic connection structure.

[0012] Furthermore, the telescopic connection structure includes two connecting rods, which are hinged in the middle and cross-arranged, and one end of the two connecting rods is connected to one of the two adjacent support rods and can move upward along the axis of the support rod, and the other end is connected to the other of the two adjacent support rods and can move upward along the axis of the support rod.

[0013] Furthermore, the telescopic connection structure is arranged below the support rod.

[0014] Furthermore, the number of the support rods is three.

[0015] Furthermore, the support rods are all hollow.

[0016] Furthermore, it also includes a fixing rod, which is connected between the two side frames and is located above the supporting rod fixed to the cross rod.

[0017] Furthermore, there are two fixing rods, both of which are connected between the two side frames and are located above the support rod fixed to the cross rod, and the two fixing rods are spaced apart along the height direction of the side frames.

[0018] The beneficial effect of the utility model is that all the support rods that can move along the cross bar are pulled out so that the support rods are spread out a certain distance from each other. At this time, all the support rods together form a horizontal fence structure between the two side frames, which is equivalent to a cushion structure, meeting the use needs of the elderly to sit down and rest. Since one of the support rods is fixed and located at the front end of the two side frames, on the one hand, the support rod setting can play a role in connecting the two side frames, and on the other hand, after all the support rods that can move along the cross bar are moved toward the support rod fixed to the cross bar, at this time, all the support rods are retracted to the front end of the two side frames, that is, they are all located at the end of the two side frames facing forward when walking, leaving space between the two side frames for the body and legs to move, so as to avoid interference between the support rods and the legs during walking. At the same time, since the support rod is always arranged between the two side frames, and compared with the conventional integral seat cushion plate with one end hinged, the railing structure formed by the support rod with the same material will be lighter, which takes into account the use needs of sitting down and resting at any time, and takes into account the overall weight of the device. While meeting the use needs of the elderly to sit down and rest at any time, the overall weight of the device is lighter, which is more conducive to the elderly to move the entire device.

[0019] The setting of the limiting mechanism can ensure that the expansion distances of two adjacent support rods are balanced when the support rods can be expanded together to a certain distance, thereby avoiding the situation where the expansion distance between some adjacent support rods is too large and not conducive to sitting down.

[0020] The support rod of the utility model is connected to the cross bar by sleeves at both ends, which is simpler in structure than other sliding matching methods, and provides good vertical support for the support rod whether in the retracted or extended state. It can be used by pulling and pushing, which is simpler and more convenient to operate. And because the support rod forms a fence structure after being pulled out, that is, it is hollow when viewed from above, when sitting and taking a bath, the water can naturally flow out along the fence structure without accumulating at the sitting position, which is more convenient for the elderly to use when sitting and taking a bath, making the device more applicable to a wider range of scenarios.

[0024] like Figure 1 and Figure 2As shown, the utility model includes a side frame 1, a support rod 2 and a limit mechanism 3. The side frames 1 are provided with two, and both side frames 1 have a crossbar 11. Specifically, the main body structure of the side frame 1 is a bending type, such as an inverted U-shape, and the crossbar 11 is connected between the U-shapes to form a firm and stable side frame 1. More than three support rods 2 are provided and are all located between the two side frames 1. Both ends of the three or more support rods 2 are provided with sleeves 21. The sleeves 21 at one end of the three or more support rods 2 are all sleeved on the crossbar 11 of one of the side frames 1, and the other ends of the three or more support rods 2 are all sleeved on the crossbar 11 of another side frame 1. Among the three or more support rods 2, the sleeves 21 at both ends of the support rod 2 located on the outermost side are fixed to the cross bars 11 of the two side frames 1, that is, it cannot move on the cross bars 11, and the fixing method can be welding or bolt connection, and the support rod 2 is located at the front end of the two side frames 1, that is, at the end of the two side frames 1 facing the front when walking, and the sleeves 21 at both ends of the remaining support rods 2 correspond to the cross bars 11 of the two side frames 1 and have a travel range of sliding on the cross bars 11 to expand two adjacent support rods 2. The limiting mechanism 3 is used to limit the expansion distance between two adjacent support rods 2, to ensure that all support rods 2 can be expanded together to a certain distance, and to control the balance of the expansion distance between two adjacent support rods 2, to avoid the situation where the expansion distance between some adjacent support rods 2 is too large and the expansion area between other adjacent support rods 2 is too small. Among them, Figure 1 is a schematic diagram of the support rod 2 after retraction, Figure 2 It is a schematic diagram of the support rods 2 being unfolded after moving along the cross bar 11 , and at this time, there is a certain unfolding distance between adjacent support rods 2 .

[0025] The utility model provides a walking anti-fall auxiliary device for the elderly, such as Figure 2 As shown, all the support rods 2 that can move along the crossbar 11 are pulled out to spread a certain distance between the support rods 2. At this time, all the support rods 2 form a horizontal fence structure between the two side frames 1, which is equivalent to a cushion structure, meeting the needs of the elderly to sit and rest. Since one of the support rods 2 is fixed and located at the front end of the two side frames 1, on the one hand, the support rod 2 can play the role of connecting the two side frames 1, and on the other hand, Figure 1As shown, after all the support rods 2 that can move along the crossbar 11 are moved toward the support rod 2 fixed to the crossbar 11, all the support rods 2 are retracted to the front ends of the two side frames 1, that is, they are all located at the end of the two side frames 1 facing the front when walking, leaving space for the body and legs to move between the two side frames 1, avoiding interference between the support rods 2 and the legs during walking. At the same time, since the support rods 2 are always set between the two side frames 1, and compared with the conventional integral and one-end hinged seat cushion, the fence structure formed by the support rods 2 with the same material will be lighter, that is, it takes into account the use needs of sitting down and resting at any time, and takes into account the overall weight of the device. Under the condition of meeting the use needs of the elderly to sit down and rest at any time, the overall weight of the device is lighter, which is more conducive to the elderly to move the device as a whole.

[0026] The setting of the limiting mechanism 3 can ensure that the unfolding distances of two adjacent support rods 2 are balanced when the support rods 2 can be unfolded together to a certain distance, thereby avoiding the situation where the unfolding distance between some adjacent support rods 2 is too large and not conducive to sitting down.

[0027] Since the seat cushion is hinged at one end, it needs additional contact buckles, straps and other structures to fix the seat cushion after it is turned up to prevent it from tipping over. The support rod 2 of the utility model is connected to the cross bar 11 by sleeves 21 at both ends. Compared with other sliding matching methods, the structure is simpler, and it provides good vertical support for the support rod 2 whether in the retracted or extended state. It can be used by pulling and pushing, which is simpler and more convenient to operate. Since the support rod 2 forms a fence structure after being pulled out, that is, it is hollow when viewed from above, when sitting and bathing, the water can naturally flow out along the fence structure without accumulating at the sitting position, which is more convenient for the elderly to use when sitting and bathing, making the device more applicable to a wider range of scenarios.

[0028] The specific arrangement of the limiting mechanism 3 is that a limiting mechanism 3 is arranged between each two adjacent support rods 2, and the limiting mechanism 3 is connected to the two support rods 2 at the position where the limiting mechanism 3 is located. Under the condition of ensuring the balance of the unfolding distances of the two adjacent support rods 2, all the support rods 2 can be unfolded by only pulling the outermost support rod 2.

[0029] In the present utility model, in order to prevent the support rod 2 from naturally moving on the cross bar 11, the matching clearance between the sleeve 21 and the cross bar 11 can be set smaller during processing and production, so that a force can be applied to move the support rod 2, but there will be a certain resistance when moving. When the elderly sit down, the sleeve 21 is constrained by the gravity to maintain the position of the support rod 2. Further, in order to improve the reliability of the overall use of the device and ensure that the support rod 2 does not move during the elderly sitting down, a spring steel ball structure can be set at one end of the cross bar 11 away from the support rod 2 fixed to the cross bar 11. This structure is a prior art, and the principle is similar to the principle of the card bead structure on the umbrella handle. A through card hole is set on the sleeve 21 of the support rod 2 with the farthest distance from the support rod 2 fixedly connected to the cross bar 11 among the three or more support rods 2. When the three or more support rods 2 are unfolded, the spring steel ball structure is clamped into the card hole for limiting, and cooperates with the setting of the limiting mechanism 3, so that the unfolded position of all movable support rods 2 can be stably maintained.

[0030] In one embodiment of the present invention, the limiting mechanism 3 is a rope, which has a simple structure, light weight and low cost.

[0031] In another embodiment of the utility model, the limiting mechanism 3 is a telescopic connection structure. The telescopic connection structure includes two connecting rods 31, the middle parts of the two connecting rods 31 are hinged and cross-arranged, and one end of the two connecting rods 31 is connected to one of the two adjacent support rods 2 and can move along the axis of the support rod 2, and the other end is hinged to the other of the two adjacent support rods 2 and can move along the axis of the support rod 2. In this embodiment, the two connecting rods 31 can play a role in strengthening the strength of the fence structure to a certain extent, thereby improving the support strength of the fence structure.

[0032] The telescopic connection structure is arranged below the support rod 2, that is, the connection rod 31 is hinged below the support rod 2, so as to avoid the telescopic structure causing obvious discomfort when sitting down.

[0033] The number of the support rods 2 is preferably three, which can meet the supporting function and the number is not too large, so as to effectively control the overall weight of the device.

[0034] The support rods 2 are all hollow, which has the effect of reducing weight. The material of the support and sleeve 21 can be steel, aluminum alloy or other metal materials or other hard materials. The specific connection method of the connecting rod 31 and the support rod 2 is that a waist-shaped hole corresponding to the number of connecting rods 31 to be connected is opened below a single support rod 2, and the length direction of the waist-shaped hole is in the same direction as the axial direction of the support rod 2. The rotating pin at the end of the connecting rod 31 is inserted into the waist-shaped hole at the corresponding position, and the end of the rotating pin is provided with a boss structure, so that the rotating pin is limited inside the connecting rod 31 and can move in the waist-shaped hole along the length direction of the waist-shaped hole without falling out. Therefore, when the support rods 2 are unfolded, the two connecting rods 31 between the two adjacent support rods 2 rotate and open, and the rotating pin moves along the waist-shaped hole at the same time. When all the support rods 2 are retracted, the two connecting rods 31 between the two adjacent support rods 2 also rotate and retract, and the rotating pin moves along the waist-shaped hole at the same time, so as to ensure the corresponding degree of freedom.

[0035] The utility model further comprises a fixing rod 4, which is connected between the two side frames 1 and is located above the supporting rod 2 fixed to the cross bar 11, and is used to connect the two side frames 1 to enhance the overall structural stability of the device.

[0036] There are two fixing rods 4, both of which are connected between the two side frames 1 and are located above the support rod 2 fixed to the cross bar 11, and the two fixing rods 4 are spaced apart along the height direction of the side frames 1. In this arrangement, the two fixing rods 4 can not only connect the side frames 1 to increase the structural strength of the device, but also form a structure similar to a seat backrest, which can be used for back support, and is convenient for supporting the upper body of the elderly when sitting down or standing to take a bath.
