Description

Supine standing aid

The present invention is a standing assist device, in particular a standing assist device that helps patients with cerebral palsy, muscle atrophy, etc. to maintain a standing posture.

Some patients with cerebral palsy or muscle atrophy cannot rely on their own body strength to maintain a standing position. However, these patients need to use a standing position in rehabilitation or some daily life. Therefore, some industry insiders have developed an assistive device to help these patients maintain a standing position. One of the supine standing assistive devices is to let the patient's back rest against the body support frame, and let the support frame form a small angle tilt (for example, a 5° angle relative to the vertical plane), so that the patient can maintain a slightly supine position. This design can prevent the patient from falling forward and make it easier for the patient to maintain a standing position for a longer time.

The patient needs the assistance of others to move to the supine standing assistive device, and the body support frame of the supine standing assistive device can be pivoted to a horizontal state, allowing the patient to move from a chair or bed to the supine standing assistive device. However, the height of the body support frame after rotating to a horizontal state may not be consistent with the height of the chair or bed, so the process of the patient moving to the supine standing assistive device or from the supine standing assistive device to the chair or bed is relatively laborious and inconvenient.

To this end, the present invention provides a supine standing assistive device, comprising: a chassis; a lifting frame; a lifting structure, comprising a first rod and a second rod pivotally connected to each other, the first rod comprising a pair of first sliding ends pivotally connected to the chassis and a pair of first pivotal ends pivotally connected to the lifting frame, the second rod comprising a pair of second pivotal ends pivotally connected to the chassis and a pair of second sliding ends pivotally connected to the lifting frame The invention relates to a movable end; a body support frame pivotally connected to the lifting frame; a height drive device connected between the lifting structure and the chassis. When the height drive device is in operation, the lifting frame and the body support frame move together to move away from or closer to the chassis; and a tilt drive device connected between the lifting frame and the body support frame. When the tilt drive device is in operation, it pushes the body support frame to pivot relative to the lifting frame to change the tilt angle.

The lifting structure cooperates with the lifting frame, the chassis and the height drive device, so that the height of the body support frame can be changed without pivoting (horizontally), and the body support frame is adjusted to the height of the user's hips, so that the user can move the body to the body support frame more conveniently and safely. The lifting frame, the tilt drive device and the body support frame cooperate with each other, and the tilt angle of the body support frame can be adjusted without changing the height of the lifting frame and the body support frame from the ground. It is further allowed to adjust the tilt angle of the body support frame when the lifting frame is lowered to the lowest state allowed, so that the standing auxiliary device can control the center of gravity at a low position and is not easy to fall.

The present invention relates to a supine standing assistive device, and more particularly to a device for assisting a patient suffering from cerebral palsy or muscle atrophy (hereinafter referred to as a user) to maintain a standing posture. Referring to FIGS. 1 to 4, the standing assistive device 10 comprises a chassis 20 and a lifting frame 66, a lifting structure 48 is disposed between the chassis 20 and the lifting frame 66, the lifting structure 48 is constructed to support the lifting frame 66 to move away from or close to the chassis 20 without pivoting, the lifting frame 66 is pivotally and movable together with a body support frame 76, a tilting support frame 48 is disposed between the lifting frame 66 and the body support frame 76, and the lifting frame 66 is provided with a support frame 76. The driving device 139, the tilt driving device 139 operates by pushing the body support frame 76 to pivotally change the tilt angle when the lifting frame 66 is not moving. A height driving device 36 is provided between the chassis 20 and the lifting structure 48. The height driving device 36 operates by pushing the lifting structure 48 to operate, causing the lifting frame 66, the tilt driving device 139 and the body support frame 76 to move away from or close to the chassis 20 without pivoting.

The chassis 20 may include, but is not limited to, two longitudinal rods 22 that are symmetrically and parallelly spaced apart, a first cross-connecting rod 24 and a second cross-connecting rod 30 are connected between the two longitudinal rods 22, a pair of first pivots 26 and a pair of limit arms 28 are respectively disposed on both sides of the first cross-connecting rod 24, a second pivot 32 is disposed on the second cross-connecting rod 30, and the chassis 20 further includes a pair of symmetrical first rails 34, and along the length direction of the first rails 34, the first rails 34 are located between the first pivot 26 and the second pivot 32.

The lifting structure 48 includes a first rod 50 and a second rod 58 pivotally connected to each other. The first rod 50 includes a pair of first sliding ends 52 slidably connected to the chassis 20 and a pair of first pivoting ends 54 pivotally connected to the lifting frame 66. The second rod 58 includes a pair of second pivoting ends 62 pivotally connected to the chassis 20 and a pair of second sliding ends 60 slidably connected to the lifting frame 66.

The first rod 50 of the lifting structure 48 may include, but is not limited to, a middle pivot 56 between the first pivot end 54 and the first sliding end 52. The second rod 58 may include, but is not limited to, a middle pivot portion 64 between the second sliding end 60 and the second pivot end 62 and a connecting portion 65. The connecting portion 65 is located between the second sliding end 60 and the middle pivot portion 64. The first rod 50 is composed of the middle pivot portion 56 and the middle pivot portion of the second rod 58. 64 pivotally connected, the first sliding end 52 and the second sliding end 60 are located on the same side, the first pivot end 54 and the second pivot end 62 are located on the same side, and the lifting structure 48 can be but is not limited to the second sliding end 60 and the chassis 20 along a longitudinal distance perpendicular to the ground being the same as the first pivot end 54 and the chassis 20 along the longitudinal distance, so that the lifting frame 66 remains parallel to the chassis 20, and the angle of the lifting frame 66 can be but is not limited to a horizontal state.

The first sliding end 52 of the first rod 50 may be but is not limited to being composed of a roller, and the second sliding end 60 of the second rod 58 may be but is not limited to being composed of a roller. A pair of the first sliding ends 52 are slidably accommodated in a pair of the first tracks 34, and a pair of the second pivoting ends 62 are pivoted with a pair of the first pivots 26. Therefore, it can be understood that when one of the first rod 50 or the second rod 58 pivots, the other of the first rod 50 or the second rod 58 will also pivot. In addition, when the first rod 50 or the second rod 58 pivots, the distance between the second sliding end 60 and the first pivoting end 54 and the chassis 20 will change.

The height drive device 36 may be, but is not limited to, an electrically driven motor 40 driving a transmission mechanism 38 composed of gears, sprockets, or turbines. The height drive device 36 may further include, but is not limited to, a push rod 42 coupled to the transmission mechanism 38. The transmission mechanism 38 includes a first end 44 separated from the push rod 42. The push rod 42 includes a second end 46 relative to the first end 44. When the motor 40 is in operation, the push rod 42 will produce a telescopic displacement.

The first end 44 of the height drive device 36 is pivoted with the second pivot 32 of the chassis 20 and the second end 46 is pivoted with the connecting portion 65. Therefore, it can be understood that when the push rod 42 is displaced and retracted, the second sliding end 60 and the first pivot end 54 will be displaced in the direction close to the chassis 20, and when the push rod 42 is displaced and extended, the second sliding end 60 and the first pivot end 54 will be displaced in the direction away from the chassis 20.

The lifting frame 66 can be, but is not limited to, a pair of second rails 68 arranged on two symmetrical sides and a pair of third hinges 70 arranged on the other side. The lifting frame 66 also includes a coupling portion 72 located between the pair of third hinges 70. The lifting frame 66 further includes a coupling portion 72 located between the pair of third hinges 70 and a pair of inclined hinges 74.

The second sliding end 60 of the lifting structure 48 is slidably accommodated in the second track 68 and the first pivot end 54 is pivoted with the third pivot 70. Therefore, it can be understood that when the push rod 42 is displaced, the lifting frame 66 will move away from or closer to the chassis 20 along the longitudinal displacement (the lifting frame 66 remains parallel to the chassis 20).

The body support frame 76 includes a main frame 78, and the main frame 78 includes two parallel and symmetrically spaced outer rods 80, each of which includes an upper end 82 and a lower end 83, and each of which further includes a first joint 88, a second joint 90, and a plurality of height adjustment holes 86 formed on the side, each of which is located between the first joint 88 and the upper end 82, and each of which is located between the first joint 88 and the upper end 82. Between the plurality of height adjustment holes 86 and each of the second coupling parts 90, each of the first coupling parts 88 and each of the second coupling parts 90 may be formed of, but not limited to, circular holes. The main frame 78 further includes a pair of first pivoting parts 84 formed on one side of the two outer rods 80 and separated from each of the first coupling parts 88, and a second pivoting part 85 formed between the two outer rods 80. The second pivoting part 85 is located between the upper end 82 and the first coupling part 88.

The body support frame 76 further includes two connecting rods 96, a first extension frame 119 that can be optionally assembled, and a second extension frame 135 that can be optionally assembled. Each first extension frame 119 includes two first sleeve ends 131 and two second sleeve ends 133. Each second extension frame 135 includes two coupling ends 137. Each connecting rod 96 includes a first coupling end 98 and a second coupling end 111. The first extension frame 119 and the second extension frame 135 are selected according to the height of the user. Select installation, that is, when the user of the standing assisting device 10 is short (such as a primary school student), the first extension frame 119 and the second extension frame 135 can be selected not to be installed; when the user of the standing assisting device 10 is of moderate height (such as a junior high school student), only the first extension frame 119 can be selected to be installed; when the user of the standing assisting device 10 is taller (such as an adult), the first extension frame 119 and the second extension frame 135 can be selected to be installed.

The body support frame 76 shown in Figures 1, 3 to 7 of the present invention is an embodiment in which the first extension frame 119 and the second extension frame 135 are installed at the same time. Figure 8 shows an embodiment in which only the first extension frame 119 is installed. Figure 9 is an embodiment in which neither the first extension frame 119 nor the second extension frame 135 is installed. The following will explain the combination relationship of various states of the body support frame 76 one by one.

Referring to FIGS. 2 and 3 , each of the first sleeve ends 131 of the first extension frame 119 is sleeved with each of the upper ends 82 of the main frame 78, each of the coupling ends 137 of the second extension frame 135 is sleeved with each of the second sleeve ends 133 of the first extension frame 119, and the two connecting rods 96 are disposed on the outer sides of the two outer rods 80. The first coupling end 98 of each of the connecting rods 96 is coupled with each of the second coupling portions 90 and the second coupling end 111 is coupled with each of the second sleeve ends 133. Each of the first coupling ends 98 and each of the second coupling ends 111 can be coupled to each of the second sleeve ends 133 by a plurality of screws, but is not limited thereto. In addition, two of the screws pass through each of the second coupling ends 111, each of the second sleeve ends 133 and each of the coupling ends 137, and the other two screws pass through each of the first coupling ends 98 and each of the second coupling parts 90. It can be understood that each of the connecting rods 96 bridges the main frame 78, the first extension frame 119 and the second extension frame 135, so that the second extension frame 135 cannot be separated from the first extension frame 119, and the first extension frame 119 is sandwiched between the second extension frame 135 and the main frame 78, so that the first extension frame 119 cannot be separated from the main frame 78.

Referring to FIG. 8 , when the body support frame 76 only needs to be installed with the first extension frame 119, the first coupling end 98 of each connecting rod 96 is still coupled to each second coupling portion 90, and each second coupling end 111 is still coupled to each second sleeve end 133. In this way, the first extension frame 119 is still restricted by the two connecting rods 96 and cannot be separated from the main frame 78.

In addition, please refer to Figures 7 and 8 at the same time. Although the lengths of the body support frame 76 shown in the two figures are different, the installation positions of the two connecting rods 96 shown in the two figures are the same, and the two connecting rods 96 provide two adjustment positions of the sliding sleeves 113, so that the table top 171 can be adjusted to an appropriate height position, that is, the height of the table top 171 shown in Figure 7 from the ground is higher than the height of the table top 171 shown in Figure 8 from the ground.

Referring to FIG. 9, when the body support frame 76 does not need to be installed with the first extension frame 119 and the second extension frame 135, the first coupling ends 98 of the two connecting rods 96 are coupled to the first coupling portions 88 and the second coupling ends 111 are coupled to the upper ends 82. That is, the coupling positions of the two connecting rods 96 shown in FIG. 9 are different from those shown in FIGS. 7 and 8. In this state, the position of the table top 171 can be adjusted to a position closer to the ground, so it is suitable for users of short stature.

The body support frame 76 can provide a back plate set 175 for installation (as shown in Figures 4 to 6). The back plate set 175 can include but is not limited to three parts corresponding to the main frame 78, the first extension frame 119 and the second extension frame 135. Therefore, it can be understood that the back plate set 175 is adjusted according to the assembly mode of the body support frame 76.

A sliding sleeve 113 is slidably mounted on each of the connecting rods 96. Each of the sliding sleeves 113 is pivoted with a sleeve 115. Each of the sleeves 115 is slidably or non-slidably coupled with a mounting rod 117. Two mounting rods 117 are used to provide a table top 171 assembly. Thus, when the two sliding sleeves 113 are synchronously displaced, the position of the table top 171 can be changed. Referring to FIGS. 6 and 7, if the body support frame 76 is pivoted to a nearly upright state (approximately tilted 5°), the displacement of the two sliding sleeves 113 can adjust the height of the table top 171 from the ground. Furthermore, when the two sleeves 115 are pivoted relative to the two sliding sleeves 113, the angle of the table top 171 can be adjusted.

The body support frame 76 further includes a pedal bracket 92 combined with the main frame 78. The pedal bracket 92 may include, but is not limited to, two protruding coupling ends 94. Each coupling end 94 may be selected to be coupled with at least any two of the plurality of height adjustment holes 86 of the two outer rods 80. The pedal bracket 92 is used to provide a pedal 173 assembly. It can be understood that the pedal bracket 92 can be selected to be assembled with different height adjustment holes 86 to adjust the position relative to the main frame 78, which is conducive to fine-tuning according to the height of the user.

The back panel set 175 of the body support frame 76 is used to provide back support for the user, the footrest 173 is used to provide foot support for the user, and the table board 171 is used to provide arm support for the user. The multiple straps provided on the back panel set 175 and the tilt angle of the body support frame 76 (as shown in Figures 6 and 7) can support the user to maintain a standing posture.

The tilt drive device 139 may be, but is not limited to, an electrically driven motor 153 driving a transmission mechanism 151 composed of gears, sprockets, or turbines. The tilt drive device 139 may further include, but is not limited to, a telescopic rod 155 coupled to the transmission mechanism 151. The transmission mechanism 151 includes an inner end 159 separated from the telescopic rod 155. The telescopic rod 155 includes an outer end 157 relative to the inner end 159. When the motor 153 is in operation, the telescopic rod 155 will produce a telescopic displacement.

The inner end 159 of the tilt drive device 139 is pivoted with the joint 72 of the lifting frame 66 and the outer end 157 is pivoted with the second pivot 85 of the body support frame 76, so that when the telescopic rod 155 is displaced, the lifting frame 66 remains stationary and the body support frame 76 pivots relative to the lifting frame 66 to change the tilt angle. The pivot angle of the body support frame 76 can be but is not limited to between the horizontal and vertical angles relative to the ground.

The structural features of the standing assisting device 10 of the present invention have been described in detail. The following will further illustrate the operation of the standing assisting device 10 by taking the body support frame 76 equipped with the first extension frame 119 and the second extension frame 135 as an example to help better understand the technical content of the present invention. Referring to Figures 3 and 4, assuming that the body support frame 76 is in a horizontal state parallel to the ground and the lifting frame 66 and the body support frame 76 are located closest to the chassis 20, in this state, the push rod 42 of the height drive device 36 is in a relatively retracted state and the telescopic rod 155 of the tilt drive device 139 is also in a relatively retracted state.

When the user wants to move from a bed or a chair to the standing aid device 10 where the body support frame 76 is in a horizontal state, the two mounting rods 117 together with the table top 171 can be removed first, and the height drive device 36 can be operated to extend the push rod 42 outward, and the push rod 42 can push the second rod 58 of the lifting structure 48 to pivot together with the first rod 50. The lifting frame 66, the body support frame 76, the back plate assembly 175 and the tilt drive device 139 are moved together in a direction away from the chassis 20 to increase the height from the ground. When the height of the back plate assembly 175 on the body support frame 76 is approximately the same as the height of the user's bed or chair surface, the user (who may need assistance) can easily move to the body support frame 76. For example, a user sitting on a bed can first straighten the upper body and then move the buttocks to the body support frame 76, and finally move both feet to the body support frame 76.

After the user lies completely on the body support frame 76, the user's feet can rest on the footrest 173 and the back can rest on the back panel assembly 175. The assistant can tie the multiple straps attached to the back panel assembly 175 to the user to provide more stable support. Finally, the two mounting rods 117 and the table top 171 are installed so that the user's body is between the table top 171 and the back panel assembly 175. The positions of the two sliding sleeves 113 are further adjusted so that the table top 171 is roughly between the user's armpits and belly buttons, and the table top 171 is pivoted to an appropriate angle (roughly about 90° with the back panel assembly 175) so that the user's hands can rest comfortably on the table top 171.

It is worth mentioning that, for safety reasons, it is hoped that the center of gravity of the user when using the standing assisting device 10 of the present invention is low, so as to reduce the tipping over of the standing assisting device 10. Therefore, before adjusting the angle of the body support frame 76 (which is in a horizontal state at this time), the standing assisting device 10 can, but is not limited to, preferentially control the height drive device 36 to operate so that the push rod 42 is retracted, and after the user, the body support frame 76, the lifting frame 66 and the tilting drive device 139 are moved together to the lowest position allowed, the tilting drive device 139 is further operated to operate, and the lifting frame 76 is adjusted to the lowest position allowed. While the support frame 66 remains stationary, the body support frame 76 pushes the user to pivot from a horizontal position to a vertical position. Referring to FIGS. 6 and 7, the body support frame 76 can be pivoted to an angle of about 3° to 10° with the vertical plane without limitation. In this way, the weight of the user's body will be supported by the back panel assembly 175 and the foot pedal 173, and the user's hands will be against the table board 171. This can reduce the force required for the user to support the body with his feet and prevent the user from falling forward. In this way, the standing auxiliary device 10 of the present invention can smoothly help the user maintain a standing posture.

In addition, the operation of changing the tilt angle and height from the ground of the body support frame 76 in the embodiments shown in Figures 8 and 9 is the same as that in the embodiments described in Figures 1 to 7, and thus will not be repeated.

From the structural features and operation mode of the standing assist device 10 described in the present invention, it can be understood that the standing assist device 10 includes at least the following advantages.

By means of the lifting structure 48 cooperating with the lifting frame 66, the chassis 20 and the height drive device 36, the height of the body support frame 76 can be changed without pivoting (horizontally), and the body support frame 76 is adjusted to the height of the user's hips, so that the user can move the body onto the body support frame 76 more conveniently and safely.

The lifting frame 66, the tilting drive device 139 and the body support frame 76 cooperate with each other, and the tilting angle of the body support frame 76 can be adjusted without changing the height of the lifting frame 66 and the body support frame 76 above the ground. It is further allowed to adjust the tilting angle of the body support frame 76 when the lifting frame 66 is lowered to the lowest allowable state, so that the standing auxiliary device 10 can control the center of gravity at a low position and is not easy to fall over.

The body support frame 76 can be installed without the first extension frame 119 and the second extension frame 135, or only with the first extension frame 119, or with both the first extension frame 119 and the second extension frame 135. Furthermore, each of the connecting rods 96 can change the assembly position so that the position adjustment space of the table top 171 is larger. Furthermore, the body support frame 76 can be suitable for users of different heights.

When the body support frame 76 is combined with the first extension frame 119 or the first extension frame 119 and the second extension frame 135, each of the connecting rods 96 can ensure that the first extension frame 119 or the first extension frame 119 and the second extension frame 135 will not fall off easily, thereby improving the safety of the standing assist device 10.

Each of the sliding sleeves 113 can be movably coupled to each of the connecting rods 96, so that the table top 171 allows for position adjustment, and thus the table top 171 can be adjusted to the most appropriate position for the user.

The pedal bracket 92 cooperates with the plurality of height adjustment holes 86, thereby allowing the height of the pedal bracket 92 to be fine-tuned according to the actual needs of the user.

The basic teachings of the present invention have been described, and many extensions and variations will be obvious to those with ordinary skills in this field. For example, the height drive device 36 may not be an electric type device, for example, the height drive device 36 may also use a pneumatic rod. Or the tilt drive device 139 may not be an electric type device, for example, the tilt drive device 139 may use a pneumatic rod.

Since the invention disclosed in the specification can be implemented in other specific forms without departing from the spirit or general features of the invention, and some of these specific forms have been pointed out, the embodiments disclosed in the specification should be regarded as illustrative rather than restrictive. The scope of the invention is defined by the scope of the attached patent application, not by the above description, and all changes that fall within the equivalent meaning and scope of the patent application will still be included in its scope.
