Description

Technical Field

[0001] This utility model relates to the field of bed-starting assist devices, specifically to an assistive rope structure. Background Technology

[0002] Getting up is very easy and a normal thing for normal people, but it is extremely difficult for special groups such as the elderly, patients, and the disabled. Getting up without assistance can easily lead to accidents or make it impossible to get up at all. Therefore, a pull rope is usually installed on the bed to help people get up.

[0003] Existing pull cords typically consist of two cords connected to several handles, with one end of each cord firmly fixed to the foot of the bed. When needing to get up, one holds the handles and pulls the cord to assist in getting out of bed. However, existing pull cords have certain shortcomings. During the day or when not resting in bed, the cords are usually scattered on the bed, making it inconvenient to tidy up the duvet cover. To facilitate tidying up the duvet cover or to avoid affecting the aesthetics, the fixed cords need to be removed, which is time-consuming and laborious. Therefore, this utility model proposes a pull cord structure. Utility Model Content

[0004] The purpose of this utility model is to provide an assistive rope structure in order to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A power-assisted pull rope structure, comprising:

[0007] A winding box has a through slot on one side, and a winding rod rotatably passes through the inner wall of the winding box on the opposite side. Two fabric strips with movable ends passing through the through slot are fixed on the winding rod. Several handles are arrayed between the two fabric strips. Both ends of the winding rod are connected to the inner wall of the winding box with a spiral spring. The winding box is provided with a locking device for locking the winding rod.

[0008] The fastener, located on the winding box, is used to secure the winding box to the bed.

[0009] Furthermore, the locking element includes a ratchet fixed on the take-up bar, a support column fixed on the take-up box, a pawl rotatably sleeved on the support column that engages with the ratchet, and a torsion spring sleeved on the support column connecting the pawl and the take-up box.

[0010] Furthermore, two limiting discs are fixed on the winding rod, and the two limiting discs correspond one-to-one with the two spiral springs.

[0011] Furthermore, limiting rods are fixed to the free ends of the two fabric strips, and the length of the limiting rods is greater than the length of the through groove.

[0012] Furthermore, a slide rod is slidably inserted through both sides of the winding box and the through groove. A buffer plate is fixed at one end of the slide rod, and a buffer spring sleeved on the slide rod is installed between the buffer plate and the winding box.

[0013] Furthermore, a rubber sleeve is fitted onto the grip.

[0014] Furthermore, two rollers are rotatably arranged on opposite sides of the inner wall of the through groove.

[0015] Furthermore, the fixing component includes a U-shaped frame fixed on the winding box, a first arc-shaped block fixed on one inner wall of the U-shaped frame, a lead screw threaded through the other inner wall of the U-shaped frame, and a second arc-shaped block rotatably connected to the end of the lead screw.

[0016] The beneficial effects of this utility model are as follows: In this utility model, by fixing a winding box at the foot of the bed and fixing one end of the two fabric strips to the winding rod, the fabric strips can be automatically wound up using the elastic force of the spiral spring.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, an embodiment of the present invention provides a power-assisted pull rope structure, comprising:

[0026] The winding box 1 has a through slot 2 on one side. A winding rod 3 rotates through the inner wall of the winding box 1 on the opposite side. Two fabric strips 4 with movable ends through the through slot 2 are fixed on the winding rod 3. Several handles 5 are arrayed between the two fabric strips 4. Preferably, the length of the fabric strips 4 is greater than the length of the headboard. In actual use, the winding box 1 is fixed at the foot of the bed. By connecting several handles 5 to the two fabric strips 4, people of different heights can hold the handles 5 and switch between different handles 5 to assist in getting up while pulling the fabric strips 4. Both ends of the winding rod 3 are connected to the inner wall of the winding box 1 with a spiral spring 6. The winding box 1 is provided with a locking piece 7 for locking the winding rod 3. In the initial state, under the elastic force of the spiral spring 6, the winding rod 3 rotates, thereby winding the two fabric strips 4 around the winding rod 3, thus storing the fabric strips 4 and handles 5 in the winding box 1. When going to sleep at night, pulling the handles... The fabric tape 4 drives the winding rod 3 to rotate, thereby compressing the spiral spring 6. When the fabric tape 4 is fully taut or removed from the winding box 1, the spiral spring 6 is in a charged state. The winding rod 3 is locked by the locking piece 7, thus keeping the spiral spring 6 in a charged state, preventing the fabric tape 4 from retracting into the winding box 1. When sleeping at night, the fabric tape 4 can be placed beside you. When getting up, you can hold the handle 5 and pull the fabric tape 4 to assist in getting up. After getting up, release the locking piece 7 from the winding rod 3. Under the action of releasing the elastic force, the spiral spring 6 drives the winding rod 3 to rotate automatically, thereby winding up and storing the fabric tape 4 and the handle 5, so as not to affect the normal arrangement of the duvet cover and to improve the aesthetics. The fixing piece 8 is set on the winding box 1 and is used to fix the winding box 1 to the bed frame. The fixing piece 8 fixes the winding box 1 to the foot of the bed, so that it does not take up too much bed space when in use or stored.

[0027] In this solution, by fixing the winding box 1 at the foot of the bed, one end of each of the two fabric strips 4 is fixed to the winding rod 3. The elastic force of the worm spring 6 can automatically wind up the fabric strips 4. When needed, the fabric strips 4 are pulled out of the winding box 1 and the winding rod 3 is locked by the locking piece 7. When not in use, the locking piece 7 is released, and the fabric strips 4 can be automatically wound up and stored under the elastic force of the worm spring 6, thereby improving practicality.

[0028] like Figure 5 As shown, the specific structure of the locking component 7 of this utility model is disclosed. The locking component 7 includes a ratchet 701 fixedly mounted on the winding rod 3, a support column 702 fixedly mounted on the winding box 1, a pawl 703 rotatably mounted on the support column 702 and engaging with the ratchet 701, and a torsion spring 704 mounted on the support column 702 connecting the pawl 703 and the winding box 1. Figure 5 As shown, in the initial state without external interference, under the elastic force of the torsion spring 704, the end of the pawl 703 is engaged in the ratchet tooth of the ratchet 701. Figure 5 Combination Figure 1 As shown, when the fabric belt 4 is needed, pulling the fabric belt 4 drives the winding lever 3 to rotate. The winding lever 3 drives the ratchet 701 to rotate counterclockwise. When it rotates counterclockwise, the pawl 703 will spring out, so as not to affect the normal pulling and extension of the fabric belt 4. However, it will restrict the winding lever 3 from rotating clockwise, so that the fabric belt 4 will not retract into the winding box 1 after being pulled and extended. When the fabric belt 4 is not in use and needs to be stored, press the pawl 703 to disengage its end from the teeth of the ratchet 701. At this time, the locking of the winding lever 3 is released. Under the elastic force of the worm spring 6, the winding lever 3 can be driven to rotate to wind and store the fabric belt 4.

[0029] like Figure 3 As shown, this utility model discloses a further technical solution for the spiral spring 6. Two limiting discs 9 are fixedly provided on the winding rod 3, and the two limiting discs 9 correspond one-to-one with the two spiral springs 6, as shown... Figure 3 As shown, by fixing two limiting discs 9 on the winding rod 3, a limiting space is formed between the limiting discs 9 and the inner wall of the winding box 1. The worm spring 6 is exactly within the limiting space. The limiting space limits the worm spring 6, so that the worm spring 6 can only deform radially, so as to maximize the use of the elastic force of the worm spring 6, thereby improving its practicality.

[0030] like Figure 1As shown, the present invention discloses a further technical solution for the fabric tape 4. The free ends of the two fabric tapes 4 are fixed with limiting rods 10. The length of the limiting rods 10 is greater than the length of the through groove 2. By setting the limiting rods 10 and the length of the limiting rods 10 being greater than the length of the through groove 2, when the fabric tape 4 is stored, under the elastic force of the spiral spring 6, the limiting rods 10 will overlap with the outer wall of the winding box 1. This not only prevents the fabric tape 4 from being completely stored in the winding box 1, making it easier to pull the fabric tape 4 for use, but also prevents the fabric tape 4 from becoming loose after winding, thereby improving practicality.

[0031] like Figure 4 As shown, a further technical solution for the fabric tape 4 is disclosed in this utility model. A sliding rod 11 is slidably inserted through both sides of the winding box 1 and the through groove 2. A buffer plate 12 is fixed to one end of the sliding rod 11. A buffer spring 13 is installed between the buffer plate 12 and the winding box 1, sleeved on the sliding rod 11. Since the fabric tape 4 is automatically wound by releasing the elastic force of the worm spring 6, the fabric tape 4 will quickly wind up during the spring force reset process, causing the limiting rod 10 to collide hard with the winding box 1. By setting the buffer plate 12, when the winding is performed using the elastic force of the worm spring 6, the limiting rod 10 will touch the buffer plate 12. Under stress, the buffer plate 12 will drive the sliding rod 11 to slide and squeeze the buffer spring 13. By using the elastic force of the buffer spring 13 for buffering, the limiting rod 10 is prevented from hard impacting the winding box 1, thus protecting it and improving its service life.

[0032] like Figure 1 and Figure 2 As shown, the present invention discloses a further technical solution for the grip bar 5. A rubber sleeve 14 is provided on the grip bar 5. Preferably, the rubber sleeve 14 has anti-slip texture. By providing the rubber sleeve 14, not only is the comfort of holding the grip bar 5 improved, but its stability is also improved, thereby improving its practicality.

[0033] like Figure 2 As shown, a further technical solution for the winding of the fabric belt 4 is disclosed in this utility model. Two rollers 15 are rotatably arranged on opposite sides of the inner wall of the through groove 2. Since the fabric belt 4 needs to be wound on the winding rod 3, it will rub against the groove opening of the through groove 2 when it is pulled or retracted. By rotatably arranging two rollers 15 on the through groove 2, the fabric belt 4 is located between the two rollers 15, so that the fabric belt 4 rolls and contacts the rollers 15 when it is pulled or retracted, thereby reducing the rolling friction on the fabric belt 4 and improving its service life.

[0034] like Figure 6As shown, the specific structure of the fixing component 8 of this utility model is disclosed. The fixing component 8 includes a U-shaped frame 801 fixed on the winding box 1. A first arc-shaped block 802 is fixed on the inner wall of one side of the U-shaped frame 801. A screw rod 803 is threaded through the inner wall of the other side of the U-shaped frame 801. A second arc-shaped block 804 is rotatably connected to the end of the screw rod 803. When it is necessary to fix the winding box 1, the winding box 1 is placed at the foot of the bed, and the railing at the foot of the bed is placed between the first arc-shaped block 802 and the second arc-shaped block 804. The screw rod 803 is twisted to rotate and move, thereby driving the second arc-shaped block 804 to move. The first arc-shaped block 802 and the second arc-shaped block 804 clamp and abut against the railing. The frictional force of the abutment is used to fix the winding box 1.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
