However, this is not intended to limit the embodiments in accordance with the concept of the present invention to a particular disclosed form, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Prior to the detailed description, the characteristic concept of the adult walker according to the present invention is as follows.

First, in order to cope with the X-type folding method is provided on a pair of upper frames arranged up and down and parallel to each other, and installed to adjust the height relative to the upper frame, and provides an independent handle portion having a rotational joint.

Second, the ergonomic design is applied to bend inwardly from the far outside of the user to the center of the rotational joint so that the distance between the user's lower arm and hand can be adjusted more precisely than the existing integrated handle part. do.

Third, in order to prevent the user from falling back when seated on the chair, the bilateral backrest can be fixed to the handle part so that the bidirectional backrest having a length adjustment function can be fixed to each independent handle part.

Fourth, it provides a way to make the Habakkud cradle easy to detach and at the same time to allow the Habakkud cradle to rotate around the handle of the upper frame so that it can be used in the X-type folding method. There is no inconvenience in using the walker as a simple wheelchair.

Based on this concept, a preferred embodiment according to the present invention will be described in more detail.

Adult walker according to an embodiment of the present invention as shown in Figure 4, in a basic configuration a pair of lower frame 100, the wheels 110 fixed to each of the lower frame 100, each of the lower frame ( And a pair of holders 120 fixed perpendicularly to the holder 100 and mounted on the holders 120 and the lower frame 100 and detachable holder 130.

Such a configuration is not only an adult walker, but also a basic configuration provided in a conventional walker, so detailed description of these configurations is omitted.

Here, the adult walker according to the present invention includes a folding structure, wherein the pair of lower frames 100 and the pair of fixing rods 120 are provided in a separated state for folding.

And, by being connected by the folding unit 200 forming the X shape is configured to be folded, that is folds laterally.

At this time, the folding unit 200, as shown in Figure 5, the pair of fixing rods 120 includes a height control tube 140 is fixed to each fixed position from the lower frame 100.

In this case, the bar bar (BAR) protrudes toward the front of the adult walker of the present invention on a portion of the outer circumferential surface of the height control tube 140, the hanger bar (BAR) is fixed to the hanger 130 described above or When used as a simple wheelchair can be utilized as a means for seating and fixing the chair substitute means.

In addition, an outer fold bracket 210 protrudes from the outer circumferential surface of the height adjusting tube 140 in a direction in which the pair of fixing rods 120 face each other, and the upper fold bracket 210 is disposed on the lower frame 100. The lower folding bracket 230 protrudes in the same direction.

In addition, one end of the upper link 220 is hinged to the upper folding bracket 210, and one end of the lower link 240 is hinged to the lower folding bracket 230, respectively.

In addition, the other end of the lower link 240 is hinged to the other end of the upper link 220, in which the pair of lower links 240 cross each other through the central hinge 250 at the intersection point Is rotatably constrained.

Accordingly, the pair of lower links 240 may have an approximately 'X' shape based on the central hinge 250 and may be folded, ie folded and unfolded around the central hinge 250.

Through the folding unit 200, the adult walker according to the present invention can be folded, thereby reducing the volume of the portable mobile storage.

In addition, although not shown, it is possible to further install a paddle (not shown) of a structure that can be folded and unfolded in the front end of the lower frame 100, the paddle is switched to a simple wheelchair when the person sitting comfortably lift the foot It can be used to let go.

Therefore, when used as an adult pedestrian because it may interfere with the storage 130, it is preferable to fold down to rotate down, this structure is well known, so it is not illustrated.

On the other hand, as shown in Figure 4, a plurality of height adjustment holes 122 are formed at a predetermined interval in the longitudinal direction in the holder 120, the T-shaped height control pipe 140 is fitted to the holder 120. The height adjustment pipe 140, the through hole 142 is formed, the through hole 142 is fixed to the fixing bolt 144 is fastened to the height adjustment hole 122 by the height adjustment pipe 140 It is configured to adjust the height of the arbitrarily.

In addition, the handle shaft 150 is fixed to the fixed tube 146 protruding from the height control tube 140 in a T-shape, the handle shaft 150 is configured to fold the handle 160.

In this case, since the folding structure of the handle 160 is a conventional hinge structure, a detailed description thereof is omitted since it is a structure for main pipes, and the handle 160 may further include a brake lever 162.

In this case, the brake lever 162 is a pad type brake commonly used in a bicycle, and when the brake lever 162 is pushed or pulled, the brake is operated by the action of the brake pad while the wire is operated.

In addition, the support rod 170 having the same folding structure is installed on the upper end of the fixing rod 120, the lower rod 180 is fixed to the support rod 170.

Here, the habakkudae 180 may have a variety of forms to have an aesthetic, but it is shown only in a simplified form, the purpose of the Habakkudae 180 is to put both arms on the relationship mainly used by the elderly The handle 160 is a means for guiding walking in a state in which a load is loaded on the adult walker while being held.

In addition, the fixing stand 120 is further provided with a removable backrest 300 can be provided to provide a more stable ride by supporting the back of the seat, in particular the waist of the seat when used to switch to a simple wheelchair.

And as shown in the principal part top view of FIG. 6, the handle 160 can be deformed.

Of course, as described above, the handle 160 may be formed in a straight shape, but when the handle 160 is held in a state where both arms are placed on the lower cradle 180, the arms are trying to be collected inward in the human body structure. Because the handle 160 is bent inward, that is to say inwardly formed as shown in Figure 6 is easy to grasp the handle 160, even when driving in the state of holding it does not burden the shoulder muscles. This is an example of applying ergonomic features.

In addition, the structure for fluidly fixing the handle 160 may be modified as shown in FIG.

According to FIG. 7, the lever housing H is fixed to the holder 120 in a wrapping form, and the housing is equipped with a known QR lever QR to rotate the QR lever QR by 180 °. It may have a structure that can be fixed at any point.

That is, since the lever housing (H) is loosened by lifting the QR lever (QR), the lever housing (H) can be freely rotated with respect to the holder (120). It is operated in the form of firmly fixed to mesh with.

Then, the handle shaft 150 is provided with a fixed knob (N) that is screwed, hinge-couple the flow handle shaft 152 to the end of the handle shaft 150, the hinge to the end of the flow handle shaft 152 When the handle 150 is hinged and fixed to the handle bracket 162 in a state in which the handle bracket 162 is integrally provided at an angle with the engaging portion, the handle 150 is moved or folded in the horizontal direction or the vertical direction. Can be varied to various positions.

Of course, when the fixing knob (N) by turning the flow handle shaft 152 is screwed so as not to move, this function can be usefully used when folding the handle 160.

In addition, in the above example, the fixed knob N and the flow handle shaft 152 may be deformed to the structure as shown in FIG. 8 in which the handle 160 is directly fixed to the handle shaft 150.

In addition, the handle 160 flow structure using the QR lever QR described above may be applied to the handle portion 160 ′ described in a fixed manner in the prior art as shown in FIG. 9.

On the other hand, the back of the normal adult walker does not necessarily need.

However, in a simple wheelchair combined adult walker associated with the present invention, the backrest can be leaned back because the wheelchair function must be secured.

In addition, when the X-type folding structure as in the present invention has a high risk of falling back when seated, the presence of the backrest is a very important concept.

For example, as shown in Figure 10, the backrest 300 is preferably a belt type, as shown in the form having the same width, as well as the width of the central portion of the length is more wider and narrower toward both ends.

In particular, the backrest 300 may be configured to be detachable at both ends, it may be configured so that only one end is fixed and the other end can be bundled and loosened.

In addition, the backrest 200 may be fixed on the height adjusting tube 140 among the holder 120, or may be installed on the lever housing (H) provided with the QR lever (QR) described above.

In addition, in the case of a fixed point type, as shown in FIG. 10, one end may be fixed on the first hook bracket BR1 and then fixed by a tick or belt fastener method, and the other end may include a plurality of slots SL. The second hook bracket BR2 may be alternately inserted into the formed second hook bracket BR2, and may be configured to be easily pulled out.

At this time, since the shape or manner of fixing the end of the backrest 200 is various, it is not necessary to limit to the form such as a snap ring or Velcro fasteners.

In addition, in a structure in which rotation is free, such as lever housing H, one end of the backrest 300 may be fixed while the other end is released and rotated 180 ° in the opposite direction.

In addition, in the case of the two-point fixed type, it is natural that the two points can be freely unbundled and bundled when the above-described one-point fixed type is variously applied.

In addition, as illustrated in FIG. 11, one end of the slot SL protrudes the fixing key K, and one end of the backrest 300 forms a keyhole KH to penetrate the slot SL. The fixing key (K) is inserted into the keyhole (KH) of the may be fixed so as not to be separated.

Lastly, although the lower base stand 18 according to the present invention is configured to be rotatable vertically by the support rod 170, in addition, as shown in FIG. 12, one end of the lower base stand 180 can be separated and rotated. You may.

For example, according to Figure 12, one end of the lower surface of the lower stand 180 is provided with a fitting pipe 182 integrally, the other end one-touch lever housing 184 provided with a known one-touch lever 186. When fixing the installation, the fitting pipe 182 is first fixed to the support rod 170, and the lower opening 180 is rotated so that the bottom opening of the one-touch lever housing 184 contacts the support rod 170. When pressed with a strong force in the state, the lower opening is opened and the supporting rod 170 enters the one-touch lever housing 184.

After that, the one-touch lever 186 may be fixed.

Thus, when you want to remove the lower stand 180, when the one-touch lever 186 is released, and lifts the lower stand 180, the one-touch lever housing 184 opens and is naturally separated from the supporting rod 170. When the fitting pipe 182 is rotated to a desired position using the rotating shaft and then used again, the fitting pipe 182 may be reassembled in the above-described manner.

As such, the adult walker according to the present invention can be folded using the folding unit 200, thereby reducing the volume, and thus has an advantage of being easy to carry, move, and store.

In addition, the handle 160 can be folded up, down, left, and right freely or rotated, and the convenience of use is significantly increased.

In addition, since the handle 160 can be folded, the handle 160 does not touch the back when used as a simple wheelchair, so that a smooth wheelchair can be used.

In addition, by providing a backrest 300 when using a simple wheelchair can maintain a safe seating state.

Furthermore, since the position of the lower stand 180 can be configured to be in the form of a flow type to rotate up and down, the problems caused by the existing fixed type is eliminated, and in particular, does not become an obstacle when using a simple wheelchair.

Furthermore, the folding structure of the adult walker of the present invention may be modified in the form as shown in Figure 13a.

According to FIG. 13A, the pair of lower frames 100 and the pair of fixing rods 120 for folding do not use the X-type folding unit 200 in a separated state, and have an arc shape. A curved member, that is, a pair of curved first and second curved members CR1 and CR2 may be configured to be easily folded.

In this case, the end portions of the first and second curved members CR1 and CR2 facing each other may be configured to be easily and quickly folded at the starting point by being hinged to the rotary link RL.

In addition, the fixing unit 120 may further include a seating portion (SEA) made of a fabric, such as cloth, fibers, on the upper side of the first and second curved members (CR1, CR2).

In this case, of course, the seating part SEA may be diverted as necessary.

In addition, as shown in Figure 13b, c, it may further include a pair of third and fourth curved member (CR3, CR4) symmetric in the vertical direction with respect to the first and second curved member (CR1, CR2). .

This is to increase the safety while further reinforcing the seating portion (SEA) support force, and the first and second curved members (CR1, CR2) and the end of the third and fourth curved members (CR3, CR4) facing each other and The same rotary link (RL) is configured to be connected and folded.

Therefore, when folded, the first and second curved members CR1 and CR2 are folded inward, and the third and fourth curved members CR3 and CR4 are folded outward, and the third and fourth curved members ( Even if CR3 and CR4 are bent in reverse, they are folded against the rotary link RL, which is the center of rotation, so there is no problem at all.

However, since the first, second, third and fourth curved members CR1, CR2, CR3 and CR4 should not be folded in the opposite direction to the folding direction, the rotary link RL should be formed in a '종단' shape.

In addition, in order to further reinforce the configuration of the seating section SEA, safety handles HAN may be further provided on both sides of the d seating section SEA, and the seating section SEA may be designed to further increase safety. have.

At this time, the safety handle (HAN) may be in the form of connecting the holder 120 and the lower frame 100 in a substantially 'b' shape, the seating portion (SEA) is a lower portion of the safety handle (HAN). And it can be securely supported in the form of being mounted on the support rod (BO) firmly bound across the holder 120.

This safety handle HAN is also applied to the example of FIG.

In addition, as shown in Figure 13b, c, the handle 150 is installed to be able to fold the height adjustable with respect to the holder 120 can be further configured for ease of use.

That is, when the user is seated and the handle 150 is fixed to protrude toward the front when the user is seated for use in a simple wheelchair, inconvenience occurs in the seating behavior.

However, in the illustrated example, since the handle 150 can be folded, the user can easily and freely sit without interference by using the simple wheelchair to secure the upper space to be seated, thereby improving convenience. .

* In another example, in Figure 12, when the detachable lower stand 180 has a one-touch structure that can only be inserted into one side, but as shown in Figure 15, it can also be configured to be inserted and removed both sides Of course.

Here, the one-touch structure used in Figures 12 and 15, as illustrated in the perspective view in Figure 15, one side upper end of the circular one-touch lever housing 184 is formed with a cut groove 184a, rounded A part of the length is assembled through the housing hinge 184b in a partially cut state to be folded, and the fitting groove 184a is fitted with a shaft 184c linked to the one-touch lever 186, and the shaft 184c The end of the tightening knob 184d for providing a tightening force may have a screwed form.

Therefore, the tightening knob 184d is tightened or loosened, and the shaft 184c is easily inserted into and removed from the fitting groove 184a, thereby facilitating long mounting of the lower stand 180.

In addition, the adult walker according to the present invention can be configured more conveniently by modifying the form of Figure 4, as shown in FIG.

For example, the upper end of the fixing rod 120 is fixed by connecting with a connecting rod (180a), and fixed to extend the Habakchichi rod (180b) vertically at both ends of the connecting rod (180a), to the end of the Habakchichi rod (180b) The rotatable handle 160 can be simplified in a hinged manner.

* In this case, the Habakkuchi rod 180b may be detachably assembled to the Habakkuchi rod 180b, and the detachable assembly structure may be the one-touch structure of FIG. 15 described above.

In addition, as shown in FIG. 17, one side of the above-described lower stand 180 may be further provided with a removable structure of the mobile phone fixing unit 180c, and the mobile phone may be seated at an end of the mobile phone fixing unit 180c. The mobile phone holder 180d may be further provided.

As such, the adult walker that can be transformed into various forms can be configured to satisfy all tastes of consumers by diversifying according to its functions and characteristics.
