してある。(Prior Art and its Problems) As a conventional walking aid, there is one shown in FIG. 6, for example. This is designed so that a person with a disability can hold onto the leg while walking.The grip part a is placed above the leg provided with casters b, b1, and b2.Usually, the front wheel caster b1 is placed in the direction of travel. The rear wheel caster b2 is made of a fixed caster, while the rear wheel caster b2 is made of a flexible caster for easy modification. In order to obtain a stable stopping state, the rear wheel caster b2 is provided with braking mechanisms c1, c2, and when the upper levers d1, d2 are squeezed, the wires e, e1, e
2 is pulled upward, the brake piece f is strongly pressed against the outer circumferential side of the wheel g, and due to the friction at that time,
The brake is applied to the rear wheel caster b2.
しかし、このような従来の歩行補助器において

つた状態で歩行できるので、安全にしかも楽に体
の移動を行うことができる。(Effects and Examples) Users with lameness such as physically disabled people and patients 26
When moving to a desired location, the user first grasps the grip portion 27 of the walking aid 1 and stands in the stepping space 2 on the rear side, as shown in FIG. When performing normal forward walking, the front side of the walking aid 1 is directed toward the direction in which the user is about to proceed, and the front of the body is directed toward the direction of travel. This operation
Since all the casters of the walking aid 1 are adjustable casters 5, it is easy to maintain. Once the front of your body is facing the direction of travel, you can tilt your body slightly forward and start walking.You can walk while holding on to the walking aid 1, allowing you to move your body safely and easily. It can be performed.
さらに前記のように、歩行補助器１のキヤスタ

行方向に変更は自在で、いちいち歩行補助器１の
前側を進行方向に向けなくても、前後左右どの方
角にも進行方向を変えることができ、したがつて
極めて操作性および運動性の良い歩行補助手段を
提供することができる。 Furthermore, as mentioned above, all of the casters of the walking aid 1 are made up of the flexible casters 5, so the direction of movement can be changed freely, without having to point the front side of the walking aid 1 in the direction of movement each time. The direction of travel can be changed in any direction, and therefore a walking aid with extremely good operability and maneuverability can be provided.
一方、歩行補助器１は移動中に一時停止した
り、あるいは目的地に到着して停止する場合等に
おいては、速やかにしかも安定した停止状態を確
保する必要があり、このためには歩行補助器１は
効果的な制動能力、すなわちブレーキを備えてお
く必要がある。 On the other hand, when the walking aid 1 temporarily stops while moving or stops after arriving at the destination, it is necessary to ensure a quick and stable stopping state. 1. It is necessary to have effective braking capability, that is, a brake.
ところが、前記のように本発明の歩行補助器１

補助器１の前側に移るので、後輪キヤスタ５ｂの
ブレーキは効き難くなつてしまう。 However, as described above, the walking aid device 1 of the present invention
All of the casters are swivel casters 5, so if the brakes are applied independently like in a conventional brake mechanism, or if only some of them are configured to apply the brakes, the brakes may not work depending on the direction of travel. It may become less effective. for example,
If the braking mechanism 4 is provided only on the rear wheel caster 5b, there will be no problem when moving toward the rear of the walking aid 1, but when moving forward, the center of gravity of the user 26 will be on the front side of the walking aid 1. As a result, the brake of the rear wheel caster 5b becomes less effective.
したがつて、前記のように歩行補助器１の操作
性および運動性を損うことなく、しかも効きの良

ヤスタ５に、同時にブレーキがかかるようにする
必要がある。 Therefore, in order to ensure effective braking ability without impairing the maneuverability and maneuverability of the walking aid 1 as described above, it is necessary to apply the brakes to all the swivel casters 5 at the same time. There is a need to.
本発明においては、以下に説明するように、操

レーキを実現することができる。 In the present invention, as explained below, the brakes can be applied to all the swivel casters 5 at the same time by simply grasping the lever 23 of the operation unit 12 with one hand, resulting in extremely effective brakes. can do.
まず操作部１２のレバー２３を片手で握ぎり、
その一端に固定している作動ワイヤ２４を、アウ

も他端は前方駆動軸６に突設した回動片２２に固
定しているので、レバー２３に加えた力は回動片
２２に伝わり、この結果前方駆動軸６にトルクが
生じる。 First, grasp the lever 23 of the operation part 12 with one hand,
The actuating wire 24 fixed to one end of the outer wire 29 is pulled up inside the outer wire 29. Of course, this operation may be performed with both hands depending on the situation. When the actuating wire 24 is pulled upward, the actuating wire 24 is movably supported through a support hole 25 provided in the lower frame 3, and the other end is attached to a rotating piece 22 protruding from the front drive shaft 6. Since it is fixed, the force applied to the lever 23 is transmitted to the rotating piece 22, and as a result, torque is generated on the front drive shaft 6.
前方駆動軸６にトルクが生じると、この前方駆
動軸６と後方駆動軸７のそれぞれに突設してある
連動腕９間に、連動リンク１０を連結しているの
で、後方駆動軸７にもトルク７が生じる。 When torque is generated on the front drive shaft 6, since the interlocking link 10 is connected between the interlocking arms 9 protruding from each of the front drive shaft 6 and the rear drive shaft 7, the torque is also applied to the rear drive shaft 7. A torque of 7 is generated.
このように、それぞれの駆動軸６，７にトルク

向、走行とも不能となり、ブレーキがかかる結果
となる。 In this way, when torque is generated on each of the drive shafts 6 and 7, torque is also generated on the drive piece 8 protruding from the drive shaft as shown in FIG. It hits the upper end of the actuating rod 20 of the mechanism 4 and applies downward pressing force. The actuating rod 20 is fitted into a fitting hole 18 provided in a mounting cylinder section 28 above the wheels of the swivel caster 5 so as to be movable up and down, and a compression spring 19 is installed in the fitting hole 18. Because I support the bombing,
When the pressing force applied by the drive piece 8 to the actuating rod 20 becomes greater than the elastic force of the compression spring 19, the actuating rod 20 moves downward. When the actuating rod 20 moves downward, the lower side thereof is provided with teeth 21 that can freely engage with the teeth 16 provided on the upper side of the brake piece 17.
As the teeth mesh with each other, the actuating rod 20 presses the free end of the brake piece 17 downward, and the lower side of the free end of the brake piece 17 has a frictional contact surface with the outer peripheral side of the wheel 13 of the swivel caster 5. 15, making it impossible to turn or drive, resulting in the brakes being applied.
したがつて操作部１２のレバー２３を握れば、
すべての自在キヤスタ５に同時にブレーキをかけ

すればすべての自在キヤスタ５のブレーキを同時
に解除することができるので、歩行補助器１が前

動することができる。 Therefore, if you squeeze the lever 23 of the operating section 12,
The brakes can be applied to all the swivel casters 5 at the same time, and conversely, by releasing the lever 23 that is being held, the brakes on all the swivel casters 5 can be released at the same time. It can effectively brake movement in any direction.

No matter what direction you are moving in, forward, backward, left or right,
It is possible to apply brakes with good effect, and therefore, it is possible to provide an easy-to-use walking aid for people with walking disabilities.
