Description

Technical Field

[0001] The invention relates to a medical auxiliary device, in particular to a walking aid. Background Art

[0002] For patients with hemiplegia caused by stroke, whether they want to stand up from the edge of the bed or walk for rehabilitation, they must rely on assistive devices. Therefore, a support frame for assisting standing up from the edge of the bed is usually set up next to the patient's bed, and a walker for walking is placed next to the bed, so that multiple types of assistive devices must be prepared at home. In addition, most of the walkers currently used for hemiplegic patients are designed as crutches. However, when using such a crutch-type walker, because the distance between the four support points is not large, when the crutch-type walker is too close to the side of the body, if the patient's body center of gravity deviates too much due to moving steps, the patient will find it difficult to rely on the crutch-type walker to support the body, and it is easy to fall. When the crutch-type walker is supported at a position farther away from the side of the body in order to prevent falling, such a support method will make it difficult for the patient to apply force, and it is not very convenient to use. Summary of the invention

[0003] It is an object of the present invention to provide a walking aid which ameliorates at least one of the disadvantages of the prior art.

[0004] The walking aid of the present invention comprises a first tripod mechanism and a second tripod mechanism spaced apart from each other, and a gripping rod mechanism and a bridging rod mechanism spaced apart from each other between the first tripod mechanism and the second tripod mechanism.

The second tripod mechanism includes two second foot bar modules extending up and down and spaced front and back, a second upper bar extending front and back and spanning the top ends of the second foot bar modules, and a second cross bar spanning the second foot bar modules and spaced below the second upper bar. The spacing between the second foot bar modules is smaller than the spacing between the first foot bar modules, and the height of the second upper bar is smaller than the height of the first upper bar.

[0006] The gripping rod mechanism is connected to the first upper rod, and extends outwardly from the first upper rod in a left-right direction and bends downward to be connected to the second upper rod. The bridging rod mechanism is connected between the first crossbar and the second crossbar.

The connecting rod is non-rotatably locked with a positioning piece. When the first locking piece is loosened from the gripping section and the second locking piece is loosened from the supporting section, the gripping rod can be driven to swing away from the second adjustment module and lean against the first tripod mechanism, thereby changing from a gripping position to a retracted position. When the gripping rod is located at the retracted position and the positioning piece is detached from the mounting seat, the cross-connecting rod can be driven to pivot upward relative to the first cross bar toward the first tripod mechanism via the corresponding mounting seat, and pivot relative to the second cross bar via the corresponding mounting seat, thereby linking the second tripod mechanism to swing against the side of the first tripod mechanism, thereby changing from a straddling position to a retracted position.

[0010] The walker described in the present invention is characterized in that the first upper rod is penetrated by a plurality of first positioning holes spaced apart front to back, the second upper rod is penetrated by a plurality of second positioning holes spaced apart front to back, the first adjustment module has a first adjustment seat which can be installed on the first upper rod for forward and backward displacement and is connected to the grasping section, and a first positioning pin which is penetrated by the first adjustment seat and can be detachably inserted into one of the first positioning holes, the second adjustment module has a second adjustment seat which can be installed on the second upper rod for forward and backward displacement and is connected to the supporting section, and a second positioning pin which is penetrated by the second adjustment seat and can be detachably inserted into one of the second positioning holes, the grasping section is pivotally mounted on the first adjustment seat, the first locking piece is mounted on the first adjustment seat, the supporting section is embedded in the second adjustment seat so as to be horizontally swingable, and the second locking piece is mounted on the second adjustment seat.

When the first locking member is released from the gripping section and the second locking member is released from the supporting section, the gripping rod can be driven to swing away from the second adjustment module and swing against the first tripod mechanism, and change from the gripping position to the retracted position. When the gripping rod is in the retracted position and the positioning member is detached from the mounting seat, the cross-rod can be driven to pivot upward toward the first tripod mechanism relative to the first cross bar via the corresponding mounting seat, and pivot relative to the second cross bar via the corresponding mounting seat, and link the second tripod mechanism to swing against the side of the first tripod mechanism, and change from the straddling position to the retracted position.

[0031] Before the present invention is described in detail, it should be noted that similar components are denoted by the same reference numerals in the following description.

[0032] See also Figure 1 , 2 3, 4, a first embodiment of the walking aid 200 of the present invention is suitable for use by a hemiplegic user 900, and can be placed in front of the user 900 as a walking aid (such as Figure 2 ), or placed at the side to use as a crutch (as shown Figure 3 ), and can also be used as an aid for standing up from the edge of the bed (as shown in Figure 4 shown).

[0033] The walking aid 200 comprises a first tripod mechanism 3 and a second tripod mechanism 4 extending vertically and spaced apart from each other, a gripping rod mechanism 5 extending horizontally and spanning between the top ends of the first tripod mechanism 3 and the second tripod mechanism 4, and a bridging rod mechanism 6 extending horizontally and spanning between the first tripod mechanism 3 and the second tripod mechanism 4 and spaced apart below the gripping rod mechanism 5. In the present embodiment, the first tripod mechanism 3 and the second tripod mechanism 4 are generally in a state of extending upwardly and tilting toward each other, but the implementation is not limited thereto and may also be in a state of being upright and parallel.

[0034] See also Figure 1 , 5 6. The first tripod mechanism 3 includes two first foot rod modules 31 extending up and down and spaced apart from each other front to back, a first upper rod 32 extending front to back and spanning between the top ends of the first foot rod modules 31, and a first cross rod 33 extending front to back and spanning between the first foot rod modules 31 and spaced apart below the first upper rod 32.

[0035] Each first foot bar module 31 includes a first fixing rod 311 extending up and down and connected to the first upper rod 32 at its top end, a first foot bar 312 mutually sleeved with the first fixing rod 311 and used to support the ground, and a first telescopic positioning member 314. The first foot bar 312 can be telescopically adjusted up and down relative to the first fixing rod 311 to change the vertical extension length of the entire first foot bar module 31. The first telescopic positioning member 314 is installed on one of the first fixing rod 311 and the first foot bar 312, and is detachably connected to the other of the two, so that the first foot bar 312 can be telescopically adjusted and positioned relative to the first fixing rod 311.

[0036] The first upper rod 32 is radially provided with a plurality of first positioning holes 321 spaced apart from each other. The first cross bar 33 is connected between the bottom ends of the first fixing rod 311 and is located above the first foot rod 312 .

[0037] In the present embodiment, each first foot bar 312 has a plurality of telescopic positioning holes 313 which penetrate radially and are spaced apart vertically along the length thereof. Each first telescopic positioning member 314 is a positioning spring buckle which is fixedly installed in the corresponding first fixing rod 311 and radially passes out of the outer peripheral surface of the first fixing rod 311. The first telescopic positioning member 314 will be embedded in one of the telescopic positioning holes 313 of the corresponding first foot bar 312, so that the first foot bar 312 can be telescopically adjusted and positioned relative to the first fixing rod 311. Since there are many types of structures for which the length of the first foot bar module 31 can be telescopically adjusted, and they are not the focus of the present invention, they will not be described in detail, and the implementation is not limited to the above-mentioned implementation forms.

[0038] The second tripod mechanism 4 includes two second foot rod modules 41 extending up and down and spaced apart front and back, a second upper rod 42 extending front and back and spanning the top ends of the second foot rod modules 41, and a second cross rod 43 extending front and back and spanning between the second foot rod modules 41 and spaced apart below the second upper rod 42.

[0039] Each second foot bar module 41 includes a second fixing rod 411 extending up and down and connected to the second upper rod 42 at its top end, a second foot bar 412 which is sleeved with the second fixing rod 411 and is used to support the ground, and a second telescopic positioning member 414. The second foot bar 412 can be telescopically adjusted up and down relative to the second fixing rod 411 to change the vertical extension length of the entire second foot bar module 41. The second telescopic positioning member 414 is installed on one of the second fixing rod 411 and the second foot bar 412, and is detachably connected to the other of the two, so that the second foot bar 412 can be telescopically adjusted and positioned relative to the second fixing rod 411.

[0040] The second upper rod 42 is radially penetrated with a plurality of second positioning holes 421 spaced apart from each other. The second crossbar 43 is connected between the bottom ends of the second fixing rods 411 and is located above the second foot rods 412 . The second crossbar 43 is at the same height as the first crossbar 33 .

[0041] In this embodiment, the upper and lower extending heights of the second foot bar module 41 are smaller than the upper and lower extending heights of the first foot bar module 31, and the front and rear spacing of the second foot bar module 41 is smaller than the front and rear spacing of the first foot bar module 31, so that the height of the second upper bar 42 is lower than the height of the first upper bar 32, the length of the second upper bar 42 is smaller than the length of the first upper bar 32, and the length of the second cross bar 43 is smaller than the length of the first cross bar 33.

[0042] In this embodiment, each second foot bar 412 has a plurality of upper and lower intervals and telescopic positioning holes 413 for the second telescopic positioning member 414 to engage in. Since the telescopic adjustment structure design of the second foot bar module 41 is the same as that of the first foot bar module 31, it will not be described in detail.

[0043] See also Figure 5 , 6 7. The gripping rod mechanism 5 includes a first adjustment module 51 installed on the first upper rod 32, a second adjustment module 52 installed on the second upper rod 42, a gripping rod 53 installed between the first adjustment module 51 and the second adjustment module 52 in an upward and downward bending manner, and a first locking member 54 and a second locking member 55 installed on the first adjustment module 51 and the second adjustment module 52, respectively.

[0044] The first adjustment module 51 includes a first adjustment seat 511 that is sleeved on the first upper rod 32 and can be adjusted forward and backward, and a first positioning pin 514 that is screwed into the first adjustment seat 511 and inserted into one of the first positioning holes 321 of the first upper rod 32. The first adjustment seat 511 has a pivot ear 513 facing one side of the second tripod mechanism 4. By inserting the first positioning pin 514 into one of the first positioning holes 321, the first adjustment seat 511 can be adjusted and positioned relative to the first upper rod 32.

[0045] The second transfer module 52 has a second transfer seat 521 installed on the second upper rod 42 so as to be transferable forward and backward, and a second positioning pin 523 threadedly connected to and penetrating the second transfer seat 521 and penetrating one of the second positioning holes 421 of the second upper rod 42. By inserting the second positioning pin 523 into one of the second positioning holes 421, the second transfer seat 521 can be transferred and positioned relative to the second upper rod 42. The second transfer seat 521 has a clamping groove 522 with an opening facing upward and penetrating forward and backward.

[0046] Since the structural design that the first adjustment module 51 can be adjusted and positioned relative to the first upper rod 32 and the structural design that the second adjustment module 52 can be adjusted and positioned relative to the second upper rod 42 are both existing technologies and have many types, they will not be described in detail, and the implementation is not limited to the above-mentioned implementation forms.

[0047] The gripping rod 53 is generally L-shaped, and has a gripping section 531 pivotally connected to the pivot ear 513 via a vertical pivot shaft 512 and horizontally protruding toward the second tripod mechanism 4, and a supporting section 532 bent downwardly from the protruding end of the gripping section 531 and engaged in the engaging groove 522 of the second shifting seat 521. The gripping rod 53 can be operated to horizontally pivot between a gripping position straddling between the first upper rod 32 and the second upper rod 42 and a folded position swinging away from the second upper rod 42 and swinging against the side of the first tripod mechanism 3 via the pivot shaft 512. The pivoting change of the gripping rod 53 will be described later.

[0048] The first locking member 54 can be screwed downwardly and penetrated through the pivot ear portion 513 of the first adjustment seat 511 in a releasable manner, and can be radially inserted into the gripping section 531 in a releasable manner, thereby fixing the gripping section 531 in a non-pivotable manner on the first adjustment seat 511. The second locking member 55 can be screwed transversely and penetrated through the second adjustment seat 521 in a releasable manner, and can be radially inserted into the supporting section 532 in a releasable manner, thereby positioning the bottom end of the supporting section 532 in the engaging groove 522.

[0049] See also Figure 5 , 6 8. The cross-link rod mechanism 6 includes two mounting seats 61 rotatably mounted on the first cross bar 33 and the second cross bar 43, respectively, a cross-link rod 62 that can be moved forward and backward and relatively rotated across the mounting seats 61, and two positioning members 63 that are screwed and installed on the mounting seats 61, respectively.

[0050] Each mounting seat 61 has a first rotating seat tube 611 rotatably mounted on the corresponding first cross bar 33 or the second cross bar 43 , and a second rotating seat tube 613 coaxially connected to the side of the first rotating seat tube 611 and adjacent to another mounting seat 61 .

[0051] The cross-linking rod 62 is generally in a U-shape with its opening facing backwards, and has two end portions 621 extending forward and backward and respectively inserted in the second rotating seat tube 613 so as to be movable forward and backward and relatively rotatable, and a cross-linking portion 623 connected between the end portions 621. A third positioning hole 622 is radially penetrated through each end portion 621. The cross-linking rod 62 can be pivoted and changed between a horizontally supporting position between the first tripod mechanism 3 and the second tripod mechanism 4 and a vertically swinging and folding position leaning against the first tripod mechanism 3 via the mounting seat 61. The pivoting change of the cross-linking rod 62 will be described later.

[0052] Each positioning member 63 passes through the corresponding first rotating seat tube 611, and is radially threaded through the first rotating seat tube 611 and the second rotating seat tube 613, and passes through the corresponding first cross bar 33 or the second cross bar 43, and passes through the corresponding third positioning hole 622 of the end 621, thereby locking the corresponding mounting seat 61, the corresponding first cross bar 33 or the second cross bar 43, and the cross-link rod 62 together.

[0053] See also Figure 1 , 2 When the first embodiment of the walker 200 of the present invention is used, if it is to be placed in front of the user 900 as a walking aid, the first tripod mechanism 3 and the second tripod mechanism 4 can be adjusted to be spaced apart from each other, so that the first tripod mechanism 3 with a higher height is located on the side of the user 900 where the user 900 can move normally, and the cross-connection rod 62 is adjusted to be in a U-shaped state with the opening side facing the user 900, so that the first tripod mechanism 3 and the second tripod mechanism 4 are respectively located on the left and right sides of the normal lower limbs of the user 900, that is, the second tripod mechanism 4 with a lower height is relatively between the two feet. At this time, the user 900 can grasp the gripping rod 53 with a normal hand to support the upper body, and the walker 200 can be used to assist walking.

[0054] See also Figure 1 , 3When the walker 200 is to be placed at the side of the user 900 to be used as a crutch, the walker 200 can be rotated and adjusted to a posture in which the first leg frame mechanism 3 is in front and the second leg frame mechanism 4 is in the back. Then, the user 900 can grasp the gripping rod 53 located beside the body with a normal hand to support the upper body and use it as a crutch. When the walker 200 is moved forward for a distance, and then the user 900 grasps the gripping rod 53 and steps forward, because the left-right spacing of the second leg bar module 41 of the second leg frame mechanism 4 is small, that is, the left-right width of the second leg frame mechanism 4 is narrow, the foot of the user 900 adjacent to the side of the walker 200 will not hit the second leg frame mechanism 4 when stepping forward, and because the first leg frame mechanism 3 and the second leg frame mechanism 4 are roughly distributed on the front and back sides of the body, and the left-right span of the first leg bar module 31 and the second leg bar module 41 is large, it can provide excellent support stability in the front-back and left-right directions, and can stably support the user 900.

[0055] See also Figure 1 , 4 When the walker 200 is used as an aid for standing up from the bedside, the second leg mechanism 4 with a lower height can be turned toward the bedside, and the first leg mechanism 3 with a higher height can be relatively away from the bedside. Then, the user 900 faces the second leg mechanism 4 and grasps the first upper rod 32 and the second upper rod 42 with both hands, or grasps the first upper rod 32 and the gripping rod 53 with both hands to help prop up the body forward.

[0056] See also Figure 1 , 5 6. When the gripping rod 53 needs to be shifted forward and backward, the first positioning pin 514 and the second positioning pin 523 can be driven to separate from the first upper rod 32 and the second upper rod 42 respectively, and the gripping rod 53 can be pushed and pulled forward and backward to drive the first shifting seat 511 and the second shifting seat 521 to shift forward and backward relative to the first upper rod 32 and the second upper rod 42 respectively. After the shifting, the first positioning pin 514 is inserted into one of the first positioning holes 321 of the first upper rod 32, and the second positioning pin 523 is inserted into one of the second positioning holes 421 of the second upper rod 42, and the shifting is completed.

[0057] See also Figure 1 , 910. When the walker 200 is to be folded, the gripping rod 53 and the cross-linking rod 62 are operated to be moved to the folded position in sequence. When the gripping rod 53 is to be moved to the folded position, the first locking member 54 and the second locking member 55 are operated to be separated from the gripping section 531 and the supporting section 532 of the gripping rod 53 respectively. Then, the gripping rod 53 is pushed forward or backward to drive the supporting section 532 of the gripping rod 53 to be separated from the clamping groove 522 of the second adjustment seat 521, and to be horizontally pivoted relative to the first adjustment seat 511, and to be swung against one of the first leg rod modules 31 to be limited. Then, the first locking member 54 is reset relative to the first adjustment seat 511, so that the first locking member 54 of the pivot ear portion 513 of the first adjustment seat 511 is limited and blocked against the side of the gripping rod 53 facing away from the first leg frame mechanism 3. At this time, the gripping rod 53 is already positioned at the folded position.

[0058] When the cross-linking rod 62 is driven to change to the folded position, the positioning member 63 is detached from the mounting seat 61. Then, the cross-linking rod 62 is driven to swing upward relative to the first tripod mechanism 3, so that the cross-linking rod 62 links the corresponding mounting seat 61 to swing upward relative to the first cross bar 33 toward the first tripod mechanism 3, and at the same time drives the second tripod mechanism 4 to swing upward toward the first tripod mechanism 3 through the corresponding mounting seat 61. At this time, the cross-linking rod 62 has changed to the folded position. After the walker 200 completes the folding operation, the volume can be greatly reduced, and it is convenient to store.

[0059] In the present embodiment, each end portion 62 of the jumper rod 62 is provided with only one third positioning hole 622. However, in another embodiment of the present invention, a plurality of third positioning holes 622 spaced apart from each other may be provided at each end portion 62, so that the jumper rod 62 has the function of being able to be shifted forward and backward.

[0060] See also Fig.11 , 12 The difference between a second embodiment of the walking aid 200 of the present invention and the first embodiment lies in the structural design of the gripping rod mechanism 5 and the bridging rod mechanism 6. For the convenience of description, only the differences between the embodiments will be described below.

[0061] In the second embodiment, the gripping rod mechanism 5 and the bridging rod mechanism 6 are installed between the first tripod mechanism 3 and the second tripod mechanism 4 in a non-pivotable and foldable manner.

[0062] The gripping rod mechanism 5 includes a first adjustment module 51 installed on the first upper rod 32 and can be adjusted forward and backward, a second adjustment module 52 installed on the second upper rod 42 and can be adjusted forward and backward, and an L-shaped gripping rod 53 fixed between the first adjustment module 51 and the second adjustment module 52.

[0063] The cross-linking rod mechanism 6 includes two cylindrical mounting seats 61 respectively mounted and fixed on the sides of the first cross bar 33 and the second cross bar 43, a U-shaped cross-linking rod 62 with its two ends 621 respectively inserted in the mounting seats 61 so as to be adjustable forward and backward, and two detachable positioning members 63 respectively radially penetrated in the mounting seats 61 and respectively penetrated in the ends 621. Each mounting seat 61 is radially penetrated with a plurality of front-to-back spaced adjustment and alignment holes 614. Each end 621 of the cross-linking rod 62 is radially penetrated with a third positioning hole 622.

[0064] Each positioning member 63 has a C-shaped clip portion 631 with a radial opening, and a latch portion 632 that protrudes radially outward from the curved inner surface of the clip portion 631 and passes through the opening of the clip portion 631. When the positioning member 63 is installed, the latch portion 632 passes through one of the corresponding shifting and aligning holes 614 of the mounting seat 61 and is inserted into the corresponding third positioning hole 622 of the end portion 621. Then, the clip portion 631 is elastically deformed and clipped to be positioned outside the mounting seat 61, and the installation is completed.

[0065] Since the manner of adjusting the gripping rod 53 and the bridging rod 62 forward and backward relative to the first tripod mechanism 3 and the second tripod mechanism 4 is substantially the same as that of the first embodiment, it will not be described in detail.

[0066] In summary, through the structural design of the first tripod mechanism 3 and the second tripod mechanism 4 with unequal widths and unequal heights, and the structural design of the grasping rod mechanism 5 and the bridging rod mechanism 6 which are spaced apart vertically and horizontally across the first tripod mechanism 3 and the second tripod mechanism 4, the walker 200 of the present invention has multiple uses. It can be placed in front of the user 900 as a walking aid, can also be placed at the side of the user 900 to be used as a crutch, and can be placed at the side of the bed to be used as a supporting aid when getting up from the edge of the bed. Moreover, because the first leg rod module 31 of the first tripod mechanism 3 and the second leg rod module 41 of the second tripod mechanism 4 both have a larger span, a more stable support effect can be provided in the front, back, left and right directions.

[0067] In addition, the gripping rod 53 can be folded and swung against the first leg mechanism 3, the cross-linking rod 62 can link the second leg mechanism 4 to fold and swung against the first leg mechanism 3, and the first leg module 31 and the second leg module 41 can be adjusted upward and downward, which can greatly reduce the volume of the walker 200 and facilitate transportation and storage. Therefore, the walker 200 of the present invention is indeed a very innovative and convenient and practical creation, and can indeed achieve the purpose of the present invention.

[0068] The above are only embodiments of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
