Furthermore, there is a walking assist device that can be folded back and forth and left and right. (See Patent Documents 1 and 2)
Utility Model Registration No. 2605388 Japanese Patent No. 3080943

解決しようとする課題は、従来の折り畳み式の歩行補助器は、折り畳みの機能を重視するために、ハンドルの位置や、ハンドルの操舵といった本来の歩行を補助する機能が損なわれ、安全かつ、容易に操舵がおこないにくかった点である。   The problem to be solved is that the conventional foldable walking aid emphasizes the folding function, so the function of assisting the original walking such as the position of the handle and steering of the handle is impaired, and it is safe and easy. It was difficult to steer.

そこで、本発明は、充分コンパクトに折り畳み可能で、安全かつ、操作性に優れた歩行補助器の提供を目的とする。   Therefore, an object of the present invention is to provide a walking assist device that can be folded down in a sufficiently compact manner and is safe and excellent in operability.

そこで、本発明に係る歩行補助器は、前車輪を下端に有する左右一対の前脚杆と、後車輪を下端に有する左右一対の後脚杆とを、前後折り畳み可能に上部にて枢着し、Ｘ字状に枢結された連結部材にて左右一対の上記前脚杆を左右折り畳み可能に連結した前後及び左右に折り畳み可能な歩行補助器に於て、上記前脚杆の上端に、同心状に内嵌したハンドル部を有し、該ハンドル部の高さを調整自在に固定するための固定部材を備えたものである。   Therefore, the walking aid according to the present invention pivotally attaches a pair of left and right front leg rods having a front wheel at the lower end and a pair of left and right rear leg rods having a rear wheel at the lower end so that it can be folded back and forth. In a walking aid that can be folded back and forth and left and right with a pair of left and right front leg rods connected to each other by a connecting member pivoted in an X-shape, it is concentrically connected to the upper end of the front leg rod. It has a fitted handle part and is provided with a fixing member for adjusting the height of the handle part in an adjustable manner.

また、前車輪を下端に有する左右一対の前脚杆と、後車輪を下端に有する左右一対の後脚杆とを、前後折り畳み可能に上部にて枢着し、Ｘ字状に枢結された連結部材にて左右一対の上記前脚杆を左右折り畳み可能に連結した前後及び左右に折り畳み可能な歩行補助器に於て、上記前脚杆の上端にハンドル部を連結し、該ハンドル部によって上記前脚杆と前車輪とを旋回させて操舵するように構成し、かつ、左右連結部材にて左右一対の上記前脚杆を連結し、さらに、該左右連結部材は中央で折り曲げ自在であると共に、左右各端は、コイルバネを介して、上記前脚杆に連結しているものである。   In addition, a pair of left and right front leg rods having a front wheel at the lower end and a pair of left and right rear leg rods having a rear wheel at the lower end are pivotally attached to the upper part so that they can be folded back and forth, and are connected in an X shape. In a walking aid that can be folded left and right and left and right, and a pair of left and right front leg rods connected to each other by a member, a handle portion is connected to an upper end of the front leg rod, and the handle portion connects the front leg rod to the front leg rod. The front wheels are configured to be turned and steered, and the pair of left and right front leg rods are connected by left and right connecting members.The left and right connecting members can be bent at the center, and the left and right ends are , It is connected to the front leg rod through a coil spring.

本発明の歩行補助器によれば、ハンドル部を前脚杆に内嵌した構成であるので、ハンドル部専用の取付ボス部材を歩行補助器に設ける必要がなくなり、小型化ができる。また、前輪を下端に有する前脚杆とハンドル部が同心状となるため、ハンドルの操舵性が向上されると共に、使用時の安定性が増す。また、左右一対の前脚杆をコイルバネを介して連結するので、片手操作でも左右の前車輪を旋回操作可能であると共に、コイルバネの弾性変形の自在性を利用して、一方の前車輪の不本意な左右の振れを左右連結部材を介して他方の前車輪が連動せず、安定した歩行が可能である。   According to the walking assist device of the present invention, since the handle portion is fitted into the front leg rod, it is not necessary to provide an attachment boss member dedicated to the handle portion in the walking assist device, and the size can be reduced. Further, since the front leg rod having the front wheel at the lower end and the handle portion are concentric, the steering performance of the handle is improved and the stability during use is increased. In addition, since the pair of left and right front leg rods are connected via a coil spring, the left and right front wheels can be swiveled even with one-hand operation, and the involuntary movement of one front wheel can be achieved by utilizing the flexibility of elastic deformation of the coil spring. Stable walking is possible because the other front wheel is not interlocked with the right and left runout via the left and right connecting members.

For example, the link pin 47 and the rivet pin 48 may not be used, and the bolt and nut may be used for pivoting. Further, the left and right connecting members 10 can be freely folded upward. It is also desirable to provide a member that holds the deployed state of the walking aid.

上述した本発明の歩行補助器の使用方法（作用）について説明する。
まず、図１乃至図３に示す本発明に係る歩行補助器の展開状態で、歩行補助器のハンドル部７の高さ調整をおこなう。つまり、図４に示す固定部材17の先端部17ｃがハンドル部７の調節孔15から抜けるまで固定部材17を螺退させる。そして、先端部17ｃが調節孔15から抜けると、ハンドル部７は上下にスライド可能となる。次に、ハンドル部７を使用者の扱い易い所定の高さに合わせ、固定部材17を螺進させ、調節孔15に先端部17ｃを挿通させて位置決めをおこなう。その後、固定部材17を螺進させ、当り面17ｂをスライド部13に当接させて、ハンドル部７を固定する。このとき、固定部材17の先端部17ｃは調節孔15から抜けているが、上述した、ハンドル部７のスライド部13に形成した凹溝14からは抜けていないので、ハンドル部７は不用意に回転せず上下にスライドする。 The use method (action) of the above-described walking aid of the present invention will be described.
First, the height adjustment of the handle portion 7 of the walking assist device is performed in the unfolded state of the walking assist device according to the present invention shown in FIGS. 1 to 3. That is, the fixing member 17 is screwed until the distal end portion 17 c of the fixing member 17 shown in FIG. 4 is removed from the adjustment hole 15 of the handle portion 7. When the distal end portion 17c is removed from the adjustment hole 15, the handle portion 7 can be slid up and down. Next, the handle portion 7 is adjusted to a predetermined height that is easy for the user to handle, the fixing member 17 is screwed, and the distal end portion 17c is inserted into the adjustment hole 15 for positioning. Thereafter, the fixing member 17 is screwed, the contact surface 17b is brought into contact with the slide portion 13, and the handle portion 7 is fixed. At this time, the distal end portion 17c of the fixing member 17 has been removed from the adjustment hole 15, but since it has not been removed from the concave groove 14 formed in the slide portion 13 of the handle portion 7 described above, the handle portion 7 is inadvertent. Slide up and down without rotating.

次に、本発明に係る歩行補助器具を展開状態で使用して、進行方向を変えるには、ハンドル部７を旋回させることで、前脚杆２が旋回し、前脚杆２に取着した前車輪１が旋回して進行方向が変わる。また、前車輪１はキャスター構造ではないため、ハンドル部７の操舵角と略同様の操舵角にて旋回する。また、片手でどちらか一方のハンドル部７を操舵して前車輪１を旋回させても、左右の前脚杆２，２は左右連結部材10にて連結しているので、前車輪１，１は同方向に旋回する。
さらに、凹凸のある路面を進行するときでは、一方の前車輪１が左右に振れるようなことがあっても、コイルバネ11の弾性変形許容範囲内での振れであれば、コイルバネ11が振れを減衰させて、一方の左右の振れを左右連結部材10を介して他方の前車輪１やハンドル部７への伝達を抑制する。 Next, in order to change the traveling direction by using the walking aid device according to the present invention in the unfolded state, the front leg 2 is turned by turning the handle portion 7, and the front wheel attached to the front leg 2 is attached. 1 turns and the direction of travel changes. Further, since the front wheel 1 does not have a caster structure, it turns at a steering angle that is substantially the same as the steering angle of the handle portion 7. Even if one of the handle portions 7 is steered with one hand and the front wheel 1 is turned, the left and right front leg rods 2 and 2 are connected by the left and right connecting members 10. Turn in the same direction.
Further, when traveling on an uneven road surface, even if one of the front wheels 1 may swing left and right, the coil spring 11 attenuates the swing as long as the swing is within the elastic deformation allowable range of the coil spring 11. Thus, the transmission of one of the left and right vibrations to the other front wheel 1 and the handle portion 7 via the left and right connecting member 10 is suppressed.

また、本発明に係る歩行補助器具を折り畳む時では、次に各々のハンドル部７，７をもって、前脚杆２，２を左右に接近させる。すると、前脚杆２，２と後脚杆４，４が各々上端で上述のように連結しているので、後脚杆４，４は、左右に接近する。また、前脚杆２，２にＸ字状に枢結された連結部材５，５は左右に閉じながら、スライド部材41，41を下方へスライドさせる。そして、スライド部材41，41が下方にスライドすると、スライド部材41，41に各々枢着されている側枠部材６，６の前方端が下方に下がり、左右の後脚杆４，４を左右の前脚杆２，２へ各々接近する。また、前脚杆２，２を左右に接近させた時に、リンク部材45，45が結合部材46下方へ押し下げると共に、コイルバネ11を折曲げないように係止ピン44が回転して、左右連結部材10を中央で折曲げる。よって、本発明に係る歩行補助器は前後及び左右に折り畳まれる。   When the walking aid according to the present invention is folded, the front legs 2 and 2 are moved closer to the left and right with the handle portions 7 and 7, respectively. Then, since the front leg rods 2 and 2 and the rear leg rods 4 and 4 are respectively connected at the upper ends as described above, the rear leg rods 4 and 4 approach left and right. Further, the connecting members 5 and 5 pivotally connected to the front leg rods 2 and 2 in an X-shape are slid downward while closing the left and right. When the slide members 41 and 41 slide downward, the front ends of the side frame members 6 and 6 pivotally attached to the slide members 41 and 41 are lowered downward, and the left and right rear leg rods 4 and 4 are moved to the left and right. Approach the front legs 2 and 2 respectively. Further, when the front legs 2 and 2 are moved closer to the left and right, the link members 45 and 45 are pushed down below the coupling member 46 and the locking pin 44 is rotated so as not to bend the coil spring 11, Bend at the center. Therefore, the walking aid according to the present invention is folded back and forth and left and right.

以上のように、本発明は、前車輪１，１を下端に有する左右一対の前脚杆２，２と、後車輪３，３を下端に有する左右一対の後脚杆４，４とを、前後折り畳み可能に上部にて枢着し、Ｘ字状に枢結された連結部材５，５にて左右一対の上記前脚杆２，２を左右折り畳み可能に連結した前後及び左右に折り畳み可能な歩行補助器に於て、前脚杆２の上端に、同心状に内嵌したハンドル部７を有し、ハンドル部７の高さを調整自在に固定するための固定部材17を備えているので、使用者が使用し易い姿勢となるハンドル部７の高さを自由に調節できる。また、ハンドル部７を、前脚杆２に同心状に内嵌しているので、折り畳み状態での前後の幅が従来品（図８参照）より短くなり、収納が容易にできる（本発明の実施の形態を示した図７参照）。また、ハンドル部７のスライド部13が前脚杆２に内嵌されて露出していないので、高さ調節や折り畳み作業の際に、指や衣類を挟む危険がなくなり安全が向上する。また、ハンドル部７が前脚杆２の前方から、重心バランスがより良い前脚杆２の同心状に連結されるので、操作性が向上されると共に荷重バランスの偏りに起因する前車輪１，１や後車輪３，３の浮き上がりを抑制でき、安全に使用できる。   As described above, the present invention includes a pair of left and right front leg rods 2, 2 having the front wheels 1, 1 at the lower end and a pair of left and right rear leg rods 4, 4 having the rear wheels 3, 3 at the lower end. Folding support that can be folded back and forth and left and right by connecting the pair of left and right front leg rods 2 and 2 so as to be foldable by connecting members 5 and 5 pivotally attached to the upper part so as to be foldable. Since the handle has a handle portion 7 fitted concentrically at the upper end of the front leg rod 2 and is provided with a fixing member 17 for fixing the height of the handle portion 7 so as to be adjustable. It is possible to freely adjust the height of the handle portion 7 that makes it easy to use. In addition, since the handle portion 7 is concentrically fitted in the front leg 2, the front and rear width in the folded state is shorter than that of the conventional product (see FIG. 8), and can be easily stored (implementation of the present invention). FIG. 7 showing the form of In addition, since the slide portion 13 of the handle portion 7 is fitted inside the front leg 2 and is not exposed, there is no danger of pinching fingers or clothes during height adjustment or folding work, and safety is improved. Further, since the handle portion 7 is connected from the front of the front leg 2 in a concentric manner with the front leg 2 having a better center of gravity balance, the operability is improved and the front wheels 1, 1 and Lifting of the rear wheels 3 and 3 can be suppressed, and it can be used safely.

以上のように、前車輪１，１を下端に有する左右一対の前脚杆２，２と、後車輪３，３を下端に有する左右一対の後脚杆４，４とを、前後折り畳み可能に上部にて枢着し、Ｘ字状に枢結された連結部材５，５にて左右一対の上記前脚杆２，２を左右折り畳み可能に連結した前後及び左右に折り畳み可能な歩行補助器に於て、前脚杆２の上端にハンドル部７を連結し、ハンドル部７によって前脚杆２と前車輪１とを旋回させて操舵するように構成し、かつ、左右連結部材10にて左右一対の上記前脚杆２，２を連結し、さらに、左右連結部材10は中央で折り曲げ自在であると共に、左右各端は、コイルバネ11を介して、上記前脚杆２に連結しているので、一方のハンドル部７の操舵によって、左右の前車輪１，１を容易に旋回できる。また、左右の前脚杆２と左右連結部材10をコイルバネ11を介して連結しているので、凹凸のある路面を進行するときでは、一方の前車輪１が左右に振れるようなことがあっても、コイルバネ11の弾性変形許容範囲で減衰させて、一方の左右の振れを左右連結部材10を介して他方の前車輪１に伝達しないので、悪路や障害物によって、一方のハンドル部７が不本意に左右に揺れても、他方のハンドル部７にはその左右の揺れが連動せず、安全に歩行できる。また、左右一対の前脚杆２の連動に、コイルバネ11の伸縮によって僅かに時差をつくり、どちらか一方の前脚杆が障害物に乗り上げたりしてハンドル操作を急にとられても、他方のハンドル部７は急旋回せず、安全性が向上すると共に、他方のハンドル部７を握っていた使用者の手首を痛める危険を回避できる。また、コイルバネ11を使用して連結しているので、ユニバーサルジョイント等の高価な部品を使用せず、安価に生産できる。また、左右連結部材10は中央で折り曲げ自在なので、歩行保持器具の折り畳み機能を損なわずに操舵できる。   As described above, the pair of left and right front leg rods 2 and 2 having the front wheels 1 and 1 at the lower end and the pair of left and right rear leg rods 4 and 4 having the rear wheels 3 and 3 at the lower end are foldable up and down. In a walking assist device that can be folded back and forth and left and right by connecting the pair of left and right front leg rods 2 and 2 so as to be foldable left and right by connecting members 5 and 5 pivotally attached to each other in an X shape. The handle portion 7 is connected to the upper end of the front leg rod 2, and the front leg rod 2 and the front wheel 1 are turned by the handle portion 7 to be steered. The left and right connecting members 10 can be bent at the center, and the left and right ends are connected to the front leg 2 via the coil spring 11, so that one handle portion 7 is connected. The left and right front wheels 1 and 1 can be easily turned by this steering. Further, since the left and right front leg rods 2 and the left and right connecting members 10 are connected via the coil springs 11, even when the front wheel 1 is swung to the left and right when traveling on an uneven road surface. In addition, the coil spring 11 is attenuated within the elastic deformation allowable range, and one of the left and right vibrations is not transmitted to the other front wheel 1 via the left and right connecting members 10, so that one of the handle portions 7 is not allowed due to a bad road or an obstacle. Even if it intentionally swings left and right, the other handle portion 7 does not interlock with the left and right swing, and can walk safely. In addition, when the pair of left and right front leg rods 2 is interlocked, a slight time difference is created by the expansion and contraction of the coil spring 11, and even if one of the front leg rods gets on an obstacle and the handle operation is suddenly taken, the other handle The part 7 does not make a sudden turn, improving safety and avoiding the risk of damaging the wrist of the user holding the other handle part 7. In addition, since the coil springs 11 are used for connection, expensive parts such as universal joints are not used, and production can be performed at low cost. Further, since the left and right connecting members 10 can be bent at the center, they can be steered without impairing the folding function of the walking holding device.
