Description

A walker that prevents the user from falling forward

The invention is a walking device capable of preventing a user from falling forward, in particular, an abutting rod is arranged at an inclined angle at the front end of the walking device, so that when the user walks through the walking device, even if the hands are weak Or if the balance is not good, causing the walker to be skewed, the abutment lever will be able to support the ground first, preventing the user from falling forward with the walker.

According to the improvement of living standards and health care, the average life expectancy of Chinese people has increased, and the proportion of the elderly population has continued to increase. According to statistics, Taiwan has entered an aging society in 1993 (that is, the population over 65 years old accounts for the total population). 7%), and it is estimated that in 2025, it will enter a super-aging society (ie, the population over 65 years old accounts for 20% of the total population). Under the gradual change of social structure, the demand and consumption potential of the silver-haired people have gradually attracted attention. Markets such as health food, biochemical technology, rehabilitation equipment, and home care have emerged, and related companies have racked their brains to existing products. Carrying out research and development and improvement, we can establish a unique brand reputation with better quality.

In the silver hair market, the demand for “rehabilitation equipment” is the most obvious. Because the quality of rehabilitation equipment is good, it will directly affect the speed of patient recovery and the safety during rehabilitation. The "walker" is taken as an example to illustrate the shortcomings of the conventional product: as shown in Fig. 1, the walker 1 is composed of a bipod 11 and a plurality of crossbars 12, each of which is 11 Two support legs are respectively arranged on the bottom, and a handle 110 is respectively arranged on the top of the top, and the two ends of the cross bars 12 are respectively connected to the stand 11 so as to be able to surround a support space between the stand 11 between. When a user is inconvenient to move (eg, lower limb injury, poor balance, etc.) and needs to walk through the walker 1, the user must first grasp the grips 110 with both hands so that the lower body is located there. In the walking space, lift the walker 1 with both hands and move it forward a predetermined distance (for example, 50 cm). Hey, the user needs to support the weight of the body with both hands to open the feet. The lower body is re-entered into the walking space, so that the user can assist the user to walk safely through the assistance of the walker 1.

However, in the course of long-term research on rehabilitation equipment, the inventor found that the walker 1 is not perfect in use, mainly because the user can pass through the tripod when the user stands in the walking space. 11, to ensure the stability of the left and right direction, but once the user lifts the walker 1 with both hands, and wants to move the walker 1, the user is likely to have insufficient strength or balance feeling Preferably, the walker 1 cannot be maintained smoothly. In this case, if the user rushes forward the center of gravity, the walker 1 is likely to fall forward, and the user is accidentally dropped, which is very dangerous. .

Although the operator can change the configuration of the walker 1 (for example, increasing the front and rear length of the stand 11 to change the center of gravity of the walker 1 without being easily skewed), the occurrence of the above situation is reduced, however, if A large change in the structure of the walker 1 will significantly increase the production cost, and there will be market acceptance problems. In addition, since most of the walker structures on the market are as shown in Fig. 1, even New walkers are designed, and medical institutions may still use conventional walkers because of the cost of acquisition. Therefore, how to improve the structure of the conventional walker and design a walker that is easy to implement and can effectively prevent the user from falling down is an important subject to be solved by the present invention.

In view of the fact that when users walk through the conventional walker, they may fall into the front because of lack of strength or balance of the hands. The inventor has relied on years of experience in the development of rehabilitation equipment. After the second research and testing, the present invention finally designed a walking aid that can prevent the user from falling forward, and can provide an easy-to-implement and safe walking aid for the public.

An object of the present invention is to provide a walker capable of preventing a user from falling forward. The walker includes at least a bipod and a first crossbar, and the bottom of each of the tripods can smoothly abut The ground surface, each of the tops of the tripods is respectively provided with a holding portion, and the holding portions are maintained with a predetermined interval, which is larger than the shoulder width of the user, so as to form a walking space between the legs. The two ends of the first crossbar are respectively connected to the positions of the front ends of the tripods adjacent to the top to fix the relative positions of the tripods, and the present invention is characterized in that the walker further includes abutting a rod, the portion of the abutting rod adjacent to the top end is fixed at a middle position of the first cross rod, and the bottom end thereof extends toward the front of the walker at an oblique angle to be able to abut the front of the walker The ground. In this way, when the user lifts the walker with both hands and moves forward by a predetermined distance, even if the user's hands are insufficiently strong or the body balance is not good, causing the walker to tilt toward the front, The abutment lever will be able to abut against the ground first, so that the walker does not fall forward, thereby effectively preventing the user from easily falling forward.

Another object of the present invention is to provide a plurality of fixing holes through the abutting bar, and the walking device further includes at least one fixing component and at least two screwing components, each of the fixing components having a U shape a clamping space is formed in the middle portion of the fixing member, and a fixing portion is respectively disposed on the two ends of the fixing member, and the fixing member can be disposed on the first horizontal bar corresponding to the position of the abutting rod to make the middle portion The inner wall of the portion can tightly clamp and hold the first crossbar, and the screw can be worn The fixing holes are exposed to the outside of the abutting rod; each of the screwing elements can be respectively screwed onto each of the screwing portions to be pressed to a portion of the abutting rod adjacent to the fixing holes, so that The abutting rod can be stably integrated with the first cross bar through the fixing member and the screwing member. Accordingly, a fixing mechanism is formed through the fixing member and the screwing member, so that the abutting rod can be detachably fixed to the first crossbar.

1 is a schematic view of a conventional walker; FIG. 2 is a schematic view of a first preferred embodiment of the walker of the present invention; FIG. 3 is a partial schematic view of the walker of the present invention; and a fourth embodiment of the present invention A schematic diagram of a second preferred embodiment of the walker.

During the course of the research, the inventor found that the conventional walker 1 (as shown in Figure 1) has the problem of "easy to dump forward". The main reason is that the structure of the conventional walker 1 belongs to a kind of "four. The foot assist device, that is, the walker 1 is supported by the four support legs of the two stand 11 to the ground, and the support legs are respectively located on the left and right sides of the user, so that the front and rear directions are lacking. In the case of the support feet, it is naturally prone to fall.

The present invention "a walking aid capable of preventing a user from falling forward" is a "five-legged accessory" designed by the inventor according to the above findings. Please refer to FIG. 2, the walking aid 2 The utility model comprises at least a tripod 21, a first crossbar 22 and an abutting rod 23, wherein the bottom of each of the tripods 21 can be flat The bottom of each of the legs 21 is respectively provided with a grip portion 211 (such as a rubber sleeve or a foam sleeve), and the grips are steadily (for example, the bottom portion is provided with a stop slider). A predetermined interval is maintained between the holding portions 211, the predetermined interval being greater than the shoulder width of the user to form a walking space 210 between the legs 21. The two ends of the first crossbar 22 are respectively connected to the positions of the front ends of the legs 21 adjacent to the top to fix the relative positions of the legs 21.

The present invention is characterized in that the walker 2 is mounted against the rod 23, and the portion of the abutment rod 23 adjacent to the top end is fixed (eg, locked) in the middle position of the first cross rod 22, The bottom end extends toward the front of the walker 2 at an oblique angle to abut against the ground in front of the walker 2. Thus, since the abutment lever 23 can be used as the "fifth foot" in front of the walker 2, the lower half of the user is located in the walking space 210, and the walker 2 is lifted with both hands. And when moving forward a predetermined distance (for example, 50 cm), since the abutting lever 23 has an inclined angle, even if the user's hands lack strength or the body balance is not good, the assisting The device 2 is skewed toward the front, and the abutment lever 23 will be able to abut against the ground first, so that the walker 2 does not fall forward, thereby effectively preventing the user from easily falling forward.

The present invention utilizes the abutting lever 23 that is inclined toward the front to ensure that the walker 2 does not fall over toward the front even if it is skewed. Therefore, the inclination angle between the abutting lever 23 and the first crossbar 22 is introduced. It is better at 20 to 60 degrees. If the tilt angle is too small, the function of "preventing overturning" cannot be realized. If the tilt angle is too large, the occupied space is too large, and it is easy to contact with surrounding objects, which is unfavorable.

In addition, in the embodiment, the walker 2 further includes a second crossbar 24, and the two ends of the second crossbar 24 are respectively connected to the position of the front end of the tripod 21 adjacent to the middle section, and the position The middle portion of the second crossbar 24 is convex toward the front of the walker 2, so that the middle portion of the abutment lever 23 The intermediate portion of the second crossbar 24 can be locked to further strengthen the locking strength between the abutment bar 23 and the walker 2.

In addition, in order to enable the conventional walker to be easily modified to the structure of the invention, the abutment lever 23 can be detachably locked to the walker 2 through a fixing mechanism, see As shown in the second and third figures, the fixing rod 23 is provided with a plurality of fixing holes 230, and the fixing mechanism comprises at least one fixing element 31 and at least two screwing elements 32, and the fixing elements 31 are configured. The U-shaped portion of the fixing member 31 is formed with a clamping space 310. The two ends of the fixing member 31 are respectively provided with a screwing portion 311, and the fixing member 31 can be sleeved to the crossbars 22 and 24 corresponding to the U-shaped portion. The position of the abutting rod 23 enables the inner wall of the middle portion to tightly clamp and hold the cross bars 22, 24, and the screw portions 311 can pass through the fixing holes 230 to be exposed to The abutment rod 23 is outside.

Each of the screwing elements 32 (eg, a nut) is screwed onto each of the screwing portions 311 to be pressed to a portion of the abutting rod 23 adjacent to the fixing holes 230, so as to be The rod 23 can be stably integrated with the cross bars 22, 24 through the fixing member 31 and the screw member 32. Accordingly, since the abutting rod 23 is detachably fixed to the walker 2 through the fixing member 31 and the screwing member 32, the manufacturer can understand the conventional method. The walker performs a simple process, that is, the walker 2 of the invention is improved.

In order to improve the use and installation elasticity of the abutment rod 23, the abutment rod 23 can be designed to be telescopic (for example, the abutment rod 23 is composed of an inner tube body and an outer tube body, and the user can Controlling the length of the inner tube outside the outer tube by a bolt, so that the abutment rod 23 is only fixed to a single cross bar (ie, the first cross bar 22 or the second cross bar 24) In this case, the user can loosen the screwing element 32 according to his own needs to adjust the tilt angle between the abutting bar 23 and the crossbars 22, 24 (for example, the tilt angle is adjusted from 30 degrees to 30 degrees). 45 degrees), and By changing the length of the abutment bar 23, once the screwing member 32 is tightened again, the abutment lever 23 can be attached to the angle expected by the user.

In particular, in the foregoing embodiment, the stand 21, the first crossbar 22, the abutting bar 23, and the second crossbar 24 are independent components, respectively, but in actual practice, the operator The connection manner can still be changed according to the requirements of the production. For example, the legs 21 and the first cross bar 22 can be connected by welding, locking or socketing, or even integrally formed, and the rod 23 is abutted. It can also be fixed to each of the cross bars 22, 24 by means of locking, welding or card insertion.

In addition, in the foregoing embodiment, the abutting rod 23 is detachably locked to the walker 2 through a fixing mechanism, so that the conventional walker can be easily processed into the invention. The walker 2, but in fact the manner in which the abutment rod 23 is fixed is not limited thereto. Referring to FIG. 4, in a second preferred embodiment of the present invention, the walker 2 also includes a bipod 21, a first crossbar 22, a second crossbar 24, and an abutment bar 23. The two corresponding portions of the second crossbar 24 are respectively provided with two rods 241, one end of each of the rods 241 is spaced from the abutting rod 23 by a distance, and is welded to the second On the crossbar 24, the other end of each of the struts 241 can extend to the abutting rod 23, and is welded and integrated with the abutting rod 23, whereby the struts 241 can be left and right. The right side provides a firm supporting force, so that the stability of the abutting rod 23 can be ensured.

In the fourth figure, the reason why the struts 241 are welded to the second crossbar 24 is to prevent the user from touching or hitting the top end of the abutting rod 23 when the user leans forward, but according to For different design requirements, the operator can also design the struts 241 on the first crossbar 22, and even the operator can separately provide two struts 241 on the first crossbar 22 and the second crossbar 24. To strengthen the support stability of the abutment bar 23.

The above is only one preferred embodiment of the present invention, but the technology of the present invention The features are not limited thereto, and those skilled in the relevant art can easily recognize the equivalent changes after the technical content of the present invention, and should not depart from the protection scope of the present invention.
