Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, the present invention provides a portable nursing device including a lifting frame 100, a washing control mechanism 200, and a pin mechanism 300. The lifting frame 100 includes a movable base 110, a collapsible column 120, and a pulley mechanism 130, wherein the movable base 110 and the collapsible column 120 are rotatably connected such that the movable base 110 and the collapsible column 120 can be switched between a parallel state and a perpendicular state, and further, the pulley mechanism 130 is connected to the collapsible column 120 such that when the collapsible column 120 is in an open state, a disabled person can be displaced, for example, removed from the bed by the pulley mechanism 130 to facilitate a washing operation.

The cleaning control mechanism 200 includes a control box 21 engaged with the lifting frame 100 and a cleaning unit 22 receivable inside the control box 21.

For the purpose of convenient carrying, the collapsible column 120 is collapsed when not in operation, thereby reducing its volume. Specifically, the collapsible column 120 includes a first column 121, a second column 122, and a connecting column 123 disposed between the first column 121 and the second column 122, the number of the connecting columns 123 being at least one.

The number of connecting posts 123 is illustrated as one. The base 110, the first column 121, the connecting column 123 and the second column 122 can be switched between a rotatable state and a fixed state by the pin mechanism 300. The pin mechanism 300 may include a first pin 310, a second pin 320, a third pin 330, a fourth pin 340, a fifth pin 350, and a sixth pin 360, described below, or other pins for enabling rotation.

Wherein a first end (e.g., the lower end as shown in fig. 1) of the first post 121 is rotatably coupled to the base 110. Specifically, the first end of the first column 121 is connected to the base 110 via a first pin 310 and a second pin 320. Wherein the first column 121 is configured to be non-rotatable between the first end of the first column 121 and the base 110 when the second pin 320 is coupled to the first end of the first column 121 and the base 110, respectively. As shown in fig. 2, the first column 121 and the base 110 are perpendicular to each other, two first ears 1211 are respectively disposed at two sides of the lower end of the first column 121, the base 110 is configured as an L-shaped member, and the two first ears 1211 of the first column 121 are rotatably connected to the horizontally extending surface and the vertically extending surface of the base 110 through a first pin 310 and a second pin 320, respectively.

When the first pin 310 and the second pin 320 respectively penetrate the two first ear portions 1211 at both sides of the lower end of the first column 121, the first column 121 may be fixed to the base 110 in a manner perpendicular to the base 110. When the second pin 320 is disengaged from the first end of the first post 121 and the base 110, the first post 121 can rotate around the first pin 310. As shown in fig. 4, when the second pin 320 is removed from the first ear 1211 of the first post 121, the first post 121 can rotate along the counterclockwise direction about the first pin 310 as the rotation axis to be parallel to the base 110, so that the first post 121 and the base 110 can be folded. In addition, due to the blocking effect of the vertically extending surface of the base 110, when the first column 121 is unfolded by rotating in the clockwise direction with the first pin 310 as the rotating shaft, the first column 121 can be rotated maximally to be perpendicular to the base 110.

A second end (e.g., the upper end shown in fig. 1) of the first column 121 is rotatably connected to the connecting column 123, the second end of the first column 121 is connected to the connecting column 123 through a third pin 330 and a fourth pin 340, and the connecting column 123 is connected to the second column 122 through a fifth pin 350 and a sixth pin 360.

Wherein the connecting post 123 is configured to be non-rotatable between the connecting post 123 and the second end of the first post 121 when the fourth pin 340 is connected to the connecting post 123 and the second end of the first post 121, respectively; when the fourth pin 340 is disengaged from the connection post 123 and the second end of the first post 121, the connection post 123 can rotate about the third pin 330.

As shown in fig. 1, 2 and 3, fig. 1 shows a deployed state in which the connecting post 123 is collinear with the first post 121, and fig. 3 shows a state in which the connecting post 123 is rotated to be parallel with the first post 121. As shown in fig. 1 and 3, a second end of the first post 121 is provided with a stop block 1212, and two sides of the connection post 123 are respectively provided with a stop 1231 and a third ear 1232. The third ear portion 1232 is rotatably connected to the first post 121 via the third pin 330, so that when the connecting post 123 rotates counterclockwise to be collinear with the first post 121 using the third pin 330 as a rotation axis, the stop 1231 is matched with the stop block 1212, and the fourth pin 340 penetrates through the stop 1231 and the stop block 1212, so as to fix the connecting post 123 and the first post 121, that is, the connecting post 123 and the first post 121 are in the open state shown in fig. 1.

When the fourth pin 340 is removed, there is no restriction between the stop 1231 and the stop block 1212, so the connecting post 123 can rotate clockwise with the third pin 330 as the rotating shaft to a folded state parallel to the first post 121, as shown in fig. 2 and 3.

The above description only illustrates an embodiment of the connection column 123, but it is understood that the connection column 123 may be multiple, and the connection columns 123 are connected end to end in sequence, and each connection column 123 can be unfolded or folded by the connection action of the pin mechanism 300.

The connecting column 123 is further rotatably connected to the second column 122 (when there are a plurality of connecting columns 123, the connecting column 123 located at the outermost side after folding is rotatably connected to the second column 122), so that the first column 121, the connecting column 123 and the second column 122 are all rotated to a folded state parallel to the base 110 (as shown in fig. 4), or the first column 121 and the connecting column 123 are all rotated to an unfolded state perpendicular to the base 110 and the second column 122 is parallel to the base 110 (as shown in fig. 1).

Wherein the second post 122 is configured to be non-rotatable between the second post 122 and the connecting post 123 when the sixth pin 360 is coupled to the second post 122 and the connecting post 123, respectively; when the sixth pin 360 is disengaged from the second post 122 and the connection post 123, the second post 122 can rotate about the fifth pin 350 as a rotation axis.

As shown in fig. 3, a trapezoidal stopper 1233 is disposed at an end of the connecting column 123, and the second ear 1221 of the second column 122 is connected to the trapezoidal stopper 1233 by a fifth pin 350. The sixth pin 360 penetrates the end of the second post 122 and the stepped stopper 1233, so that the second post 122 and the connecting post 123 are in an open state perpendicular to each other (at this time, the second post 122 and the base 110 are parallel to each other). When the sixth pin 360 is removed, the second post 122 rotates counterclockwise about the fifth pin 350 as a rotation axis to a folded state where the connecting posts 123 are parallel to each other.

As shown in fig. 1, when the collapsible column 120 is fully unfolded, the first column 121 is perpendicular to the base 110, the connecting column 123 is collinear with the first column 121, and the second column 122 is perpendicular to the connecting column 123. As shown in fig. 4, when the collapsible column 120 is fully collapsed, the base 110 is stacked with a first column 121, a connecting column 123 and a second column 122 in parallel in this order. In addition, when the foldable column 120 is folded, the first column 121 and the connecting column 123 can be folded first, i.e. from the fully unfolded state shown in fig. 1 to the partially folded state shown in fig. 3; the second column 122 and the connecting column 123 are folded, and finally the first column 121 and the base 110 are folded. It will be appreciated that the above folding sequence is not essential, and the second post 122 and connecting post 123 could be folded first, or the first post 121 and base 110 could be folded first, etc.

Therefore, the foldable column 120 can be completely folded when not in use, thereby reducing the occupied space and facilitating transportation and carrying.

The number of collapsible columns 120 is at least two. Optionally, the number of bases 110 corresponds to the number of collapsible columns 120. As shown in fig. 8, two collapsible columns 120 are respectively disposed at the corresponding sides of the two bases 110. In order to improve the supporting strength of the lifting frame 100, a plurality of detachable third pillars 140 are further provided between the two collapsible columns 120. The plurality of third posts 140 are spaced apart in the Z-axis direction shown in fig. 8, and thus the third posts 140 are detachably connected to the first posts 121, the second posts 122, and the connection posts 123, respectively. In addition, a removable third post 140 may be provided between the two bases 110 to enhance strength (as shown in fig. 8 and 9). The appropriate position and number of the third posts 140 can be selected according to actual requirements.

As shown in fig. 8, two first columns 121, two second columns 122 and two connecting columns 123 are connected by a third column 140, so that two collapsible columns 120 can be connected into a whole to improve the carrying capacity. As shown in fig. 8, the third column 140 extends in the longitudinal direction (Y-axis direction shown in fig. 8) of the lifting frame 100. The base 110 extends in the horizontal direction (the X-axis direction shown in fig. 1) of the lifting frame 100.

Alternatively, the base 110 may be provided as a single structure, so that two collapsible columns 120 may be provided on both sides thereof, respectively.

A pulley mechanism 130 is supported on the lifting frame 100, the pulley mechanism 130 being used to transfer the incapacitated person 400, for example from the bed to a location convenient for cleaning, or to another support means, etc.

As shown in fig. 5 to 8, the pulley mechanism 130 includes a first fixed pulley 131, a second fixed pulley 132, a movable pulley 134, and a rope tensioner 135. Referring to fig. 1, the foldable column 120 is illustrated in a fully opened state for better explaining the pulley mechanism 130.

Both the first fixed pulley 131 and the second fixed pulley 132 are provided on the second column 122. As shown in fig. 1, when the collapsible column 120 is unfolded, the second fixed pulley 132 and the first fixed pulley 131 are offset from each other in the extending direction of the second column 122 (i.e., the X-axis direction shown in fig. 1), and the first traction rope 136 and the second traction rope 137 passing through the first fixed pulley 131 and the second fixed pulley 132 are offset from each other in the X-axis direction shown in fig. 1, so that the first traction rope 136 and the second traction rope 137 can be applied with force from both sides of the disabled person 400 when the disabled person 400 is transferred.

As shown in fig. 7, two pulley mechanisms 130 are shown, and the two pulley mechanisms 130 respectively correspond to the two foldable columns 120 on the left and right sides as shown in fig. 8, so that the two pulley mechanisms 130 may also be arranged symmetrically to each other. The pulley mechanism 130 located below will be described as an example.

As shown in fig. 7, the number of the first fixed pulleys 131 is one, the number of the second fixed pulleys 132 is two, and the two second fixed pulleys 132 are disposed at intervals along the X axis, and as shown in fig. 7, one of the second fixed pulleys 132 is offset from the first fixed pulley 131 in the X axis direction, and the other second fixed pulley 132 is disposed side by side with the first fixed pulley 131. The arrangement is such that the first traction rope 136 passes through the first fixed pulley 131, the second traction rope 137 passes through the two second fixed pulleys 132 in sequence, and the first traction rope 136 and the second traction rope 137 can be staggered in the X-axis direction, so that the first traction rope 136 and the second traction rope 137 can bear the weight of two sides of the body of the disabled person 400 respectively.

Further, in order to simultaneously drive the first traction rope 136 and the second traction rope 137, the pulley mechanism 130 further includes a guide pulley 133, and the guide pulley 133 is connected to an end of the connecting column 123 adjacent to the second column 122. As shown in fig. 1, a guide wheel 133 is located at the junction of the connecting column 123 and the second column 122. Therefore, when the collapsible column 120 is unfolded, the guide wheel 133 is located at the same height as the first fixed pulley 131 and the second fixed pulley 132.

Referring to fig. 8, the guide pulley 133 includes two side-by-side wheels corresponding to the first fixed pulley 131 and one of the second fixed pulleys 132, respectively, so that the guide pulley 133 can receive the first traction rope 136 and the second traction rope 137, respectively.

As shown in fig. 1, the movable pulley 134 is disposed on the first column 121, the movable pulley 134 is connected to the first fixed pulley 131 by a first traction rope 136, and the movable pulley 134 is connected to the second fixed pulley 132 by a second traction rope 137. Specifically, the first pulling rope 136 and the second pulling rope 137 pass through the first fixed pulley 131 and the second fixed pulley 132, respectively, then pass through the guide pulley 133 and the movable pulley 134 in sequence, and are fixed on the fixing portion 138 of the connection column 123. That is, one end of the first traction rope 136 is used for being fixed to the hanger 410 carrying the incapacitated person 400, and the other end of the first traction rope passes through the first fixed pulley 131 at the upper part of fig. 7 in sequence, then passes through one of the guide wheels 133 and one of the movable pulleys 134, passes through the movable pulley 134, is changed in direction, and is then fixed to the fixing part 138 on the connecting column 123. One end of the second traction rope 137 is used for being fixed with a lifting appliance 410 carrying the disabled person 400, and the other end of the second traction rope passes through two second fixed pulleys 132 in sequence, then passes through the other wheel of the guide wheel 133 and the other wheel of the movable pulley 134, is changed in direction after passing through the movable pulley 134, and is then fixed on the fixing part 138 on the connecting column 123

A rope tensioner 135 is disposed in the first column 121 and connected to the movable pulley 134. Wherein, when the rope tensioner 135 is operated, the movable pulley 134 is pushed to move along the extending direction of the first column 121, so as to change the height of the hanging end (i.e. the end connected with the spreader 410) of the first traction rope 136 and/or the second traction rope 137, thereby changing the position of the spreader 410, so as to lift the incapacitated person 400.

In the illustrated embodiment, the number of pulley mechanisms 130 corresponds to the number of collapsible columns 120, i.e., one pulley mechanism 130 is provided on each collapsible column 120. Referring to fig. 1, 5 and 9, the pulley mechanisms 130 of one of the collapsible columns 120 may be connected to the spreader 410 at positions corresponding to the shoulders of the disabled person 400, and the pulley mechanisms 130 of the other collapsible column 120 may be connected to the spreader 410 at positions corresponding to the legs of the disabled person 400, so that when the pulley mechanisms 130 are controlled to lift, the position and posture of the disabled person 400 can be changed; for example, the lifting of each pulley mechanism 130 is controlled to be approximately synchronous, the disabled person 400 is in a lying posture in the spreader 410 (the posture of the disabled person 400 shown in fig. 8), so as to transfer the disabled person 400 to other supporting devices; or one of the pulley mechanisms 130 may be controlled to rise higher, the disabled person 400 may be in a semi-lying position (as shown by the disabled person 400 in fig. 9) or a sitting position (as shown by the disabled person 400 in fig. 10) in the spreader 410, so that the disabled person may be cleaned after defecation.

In addition, since the rollers 111 are provided at the bottom of the base 110, when the incapacitated person 400 is lifted, the lifting frame 100 can be moved by the rollers 111, so that the incapacitated person 400 can be transferred to a desired position.

As shown in fig. 8-12, the cleaning control mechanism 200 cooperates with the lifting frame 100. Specifically, the control box 21 of the washing control mechanism 200 may be disposed between two collapsible columns 120, and the washing unit 22 on the control box 21 may perform a washing operation thereon after the lifting frame 100 moves the incapacitated person 400 to a proper position.

Specifically, as shown in fig. 13-18, the wash unit 22 includes a movable base 223, a first arm 220, and a second arm 230. As shown in fig. 11 and 15, the moving seat 223 is slidably provided on the control box 21. As shown in fig. 14, the rear end (i.e., the right end in the orientation shown in fig. 14) of the first arm 220 is pivotally connected to the movable base 223, and the first arm 220 can be rotated with a pivot point H between the first arm and the movable base 223 as a rotation point. For example, the first and

second arms

220, 230 may be rotated from the initial state shown in fig. 14 to the intermediate open state shown in fig. 16, and the second arm 230 may be further rotated to the fully open state shown in fig. 13.

Fig. 14 is a schematic view showing the folded state of the cleaning unit 22. Wherein the first arm 220 and the second arm 230 are parallel to each other, or the angle between the first arm 220 and the second arm 230 can be considered to be close to 0 °.

With continued reference to fig. 14, the movable base 223 is further provided with a first driving rod 240 and a second driving rod 250, wherein one end (i.e. the right end in the orientation shown in fig. 14) of the first driving rod 240 is rotatably connected to the movable base 223, as shown in fig. 14, the first driving rod 240 can rotate with the pivot point G of the first driving rod and the movable base 223 as a rotation point. For example, the first drive lever 240 may be rotated from the initial state shown in fig. 14 to the intermediate open state shown in fig. 16, and may also be rotated to the fully open state shown in fig. 13. The other end of the first drive lever 240 (i.e., the left end in the orientation shown in fig. 14) is pivotally connected to the first arm 220.

Wherein, in the initial state shown in fig. 14, the second arm 230 is parallel to the first arm 220, and both are parallel to the movable base 223, so that the cleaning unit 22 is in the folded state; in the intermediate opened state shown in fig. 16, the first arm 220 is driven by the first driving rod 240 to rotate to be substantially perpendicular to the movable base 223, and the second arm 230 is driven by the first arm 220 to rotate to be substantially perpendicular to the movable base 223, and at this time, the first arm 220 and the second arm 230 are still substantially parallel; in the fully opened state shown in fig. 13, the first arm 220 and the first driving lever 240 are still in a state of being substantially perpendicular to the movable base 223, and the second arm 230 is rotated to have an angle with the first arm 220 by the driving of the second driving lever 250.

As shown in fig. 14, the Y-connector 251 has a body portion 2513, a first branch 2511 and a second branch 2512. The first branch 2511 and the second branch 2512 are both rotatably connected to the body 2513, i.e., they can rotate about the pivot point E. The body 2513 is fixedly connected to the front end (i.e., the left end in the orientation shown in fig. 14) of the second drive lever 250 at a fixed point L. Further, the end of the first branch 2511 is pivotally connected to the first arm 220, and both rotate with the pivot point B as a rotation point; the end of the second branch 2512 is pivotally connected to the second arm 230 (specifically, to the second bent bar 222 of the second arm 230), and both rotate about the pivot point D.

The other end (i.e., the right end in the orientation shown in fig. 14) of the second drive lever 250 is rotatably connected to the movable base 223. As shown in fig. 14, the second driving lever 250 can rotate with a pivot point K with the movable base 223 as a rotation point.

As shown in fig. 13 and 14, the second driving rod 250 drives the Y-shaped link 251, and the body 2513 and the first and

second branches

2511 and 2512 rotate at the pivot point E, thereby changing the angle therebetween, so as to push the second arm 230 to rotate at the pivot point C, so that the angle between the second arm 230 and the first arm 220 is changed, and the second arm 230 is opened.

Referring to fig. 14 and 17, the second arm 230 includes a pivoting arm 2301 and a fixed arm 2302, and the pivoting arm 2301 rotates with a pivot point F with the fixed arm 2302 as a rotation point.
