Description

  The present invention relates to a wheelbarrow, in particular a stroller aid or a wheelchair aid.

Conventional strollers include those with a fixed backrest and those with a reclining function. (See, for example, Patent Document 1 for what can be reclined)
In addition, there are face-to-face strollers and three-wheel buggies, which range from small to large. The handle of the part where the guardian pushes the stroller has an arch type and a stick type divided into left and right. On the other hand, the handle of a wheelchair is generally a stick type.
However, the power to move the stroller or wheelchair is the power of the arm other than the electric one. As described above, the conventional baby stroller or wheelchair is inevitably fatigued of the driver's arm unless it is of an electric type. And no tools were known to reduce the burden on the arms.

JP 09-002282 A

Conventional wheelbarrows, particularly strollers and wheelchairs, have the following problems to be solved. The conventional baby stroller or wheelchair moves only by arm strength and grip force, so the driver has labor. It was necessary to keep pushing with both arms, and running with one hand was insufficient. Electric strollers or wheelchairs do not require the use of arm strength, but they are expensive, heavy and difficult to carry. Moreover, it is difficult to carry a stroller or wheelchair other than arm strength. It was difficult to think about the impact on the baby and the elderly who are riding the car.
And since there are many kinds of baby strollers and wheelchairs, it was difficult to develop assistive devices that can handle various things. Furthermore, for a place where an auxiliary tool is attached with a reclining function, it is difficult to attach the auxiliary tool to a portion under the handle because there is a problem that the auxiliary tool gets caught in the head when the reclining is tilted.
In view of the above-mentioned conventional drawbacks, the present invention makes it possible to move a stroller or wheelchair using not only the grip strength but also the power of the torso, and it is inexpensive and compatible with all types of strollers and wheelchairs without using the power of electricity. The object of the present invention is to provide a wheelbarrow that assists driving that adapts to the body shape of the driver and reduces the labor of the driver, in particular, a stroller aid or a wheelchair aid.

The above-described problem is caused by hitting the elastic material when the driver moves forward by sandwiching a resilient material that can be attached to a plurality of types of wheelbarrows, particularly a stroller or a wheelchair, between the driver's body and the stroller according to the present invention. In this way, the power is transmitted to the stroller or wheelchair.
The handcart of the present invention means a vehicle that is pushed by hand, such as a stroller or a wheelchair. The present invention is particularly suitable for a stroller or a wheelchair.
The stroller assisting device or wheelchair assisting device includes a resilient material, an adjustment belt, an upper fixing belt, a lower fixing belt, and a handband. The adjusting belt is a belt that is hooked on a handle portion of a stroller or a wheelchair. A belt for adhering the elastic material, including a portion that can adjust the length of the movement from the driver to a stroller or a wheelchair appropriately, and the upper fixing belt and the lower fixing belt are upper portions of the elastic material. The lower part is fixed to a stroller or wheelchair, and there is a connecting tool that has a means to adjust the length and the tip can be connected like a hook-and-loop fastener, and the handband can be used without a hand. Wrist to prevent the driver from leaving the stroller or wheelchair by being able to push The can be solved by stroller or wheelchair aid, characterized in that including those through.

According to a preferred aspect of the present invention, the shape of the elastic material is a kamaboko shape or a curved donut shape that is halved like a half moon, and the material is sponge, plastic, metal, or floating ring. Including those with air springs, etc.
It absorbs the impact transmitted during the driver's advancement, but has the appropriate elasticity to transmit the force to advance the stroller as soon as possible. The tip or flat part of the auxiliary tool contacts the stroller or the wheelchair's skeleton. It is a shape that can convey the force that the person stepped on.

  According to a preferred aspect of the present invention, the shape of the elastic member is a half-moon shaped donut shape that can be passed without the elastic member being caught on the head when the stroller or wheelchair reclining function is used. It has a three-dimensional U-shape including a half-shaped shape.

According to a preferred embodiment of the present invention, in order to enable the power of the contact portion to be effectively transmitted and used even in a model in which the framework portion of the stroller or the wheelchair is not vertically and horizontally but inclined, it is possible to contact the body. A connecting tool called a small elastic material for changing the tip angle, which is attached to the tip or the flat part of both ends of the elastic material for adjusting the angle of the connecting portion for transmitting the force while keeping the elastic material to be parallel Is provided.
According to a preferred aspect of the present invention, the tip-angle-changing small elastic material having the inclination has a connector for connecting to the elastic material, and a hook-and-loop fastener or the like is optimal for detachment.
According to a preferred aspect of the present invention, the stroller assisting device can be attached to a plurality of types of wheelchairs on the same principle, and has the same effect.
According to a preferred aspect of the present invention, when the driver moves forward, the portion where the elastic material is applied to the body extends downward from the abdominal portion to the knee portion of the foot as a range of the body portion.

The present invention has the following effects.
Conventional strollers are tired of their arms and hands, but using this aid can greatly reduce arm fatigue. Because it uses leg strength and muscles of the entire lower abdomen, the driver's posture, which tends to be stooped, can be straightened, and motor functions that can make full use of the whole body can be found in strollers or wheelchairs.
And since the assisting device can be adjusted, it can be used most appropriately and effectively regardless of the shape of the person pushing the stroller or wheelchair.
Furthermore, by using this auxiliary tool, it is possible to go straight with just placing the hand, so that not only is it possible to run with one hand, but the power is not electric but it is cheap and lightweight for human power.
Moreover, since the power generated by the assisting device is transmitted to the frame portion and moves forward, it is possible to move forward without giving a shock to the rider.
In addition, the aids can be used with a variety of strollers and wheelchairs to attach to the bones and handles that are common parts of any stroller or wheelchair.
For example, according to the effect of claim 3, since the elastic material can be U-shaped, it travels without the aid coming in contact with the head of the person riding even when the stroller or wheelchair is reclining. Things are also possible.
For example, in the effect that comes out from claim 4, the use of a removable small elastic material for connecting to support the elastic material enables use in response to diversified strollers and wheelchair frames.

The assembly order of Example 1 above is shown below.
The 1 adjustment belt is put on the left and right handles of the 6 stroller like a necklace. As a result, the kamaboko-type elastic material 2 and the stroller are connected. The reason for wearing a belt like a necklace is that it is easy to attach and detach.
The three upper fixing belts are connected to the left and right skeleton parts of the left and right babies, respectively. This is used to connect the kamaboko type 2 and the stroller in the case where the kamaboko type and the stroller are connected more firmly than the fixing by the adjusting belt 1 described above.
The 4 lower fixing belts are respectively connected to the frames that are connected in parallel to the left and right 8 grounds.
By these strokes, the kamaboko-type elastic material 2 can be pulled up and down to fix the set position, and is firmly connected to the stroller.
The material of the kamaboko type elastic material of 2 is not too soft, and is preferably an elastic material including a sponge, plastic, a metal or a material having an air spring such as a floating ring.
The 5 handband is passed through the driver's wrist. This prevents the risk of the stroller moving away from the driver's hand.
The adjustment belt of 1, the upper fixing belt of 3, the lower fixing belt of 4, and the tip of the hand band of 5 have a part whose length can be adjusted, and the driver's power is elastic material The length can be appropriately communicated to. In addition, it is preferable that the material of the portion used for length adjustment and connection at the tip of the belt is a hook-and-loop fastener that can be easily detached.

Next, the operation order is shown.
As shown by 4 in the figure, the driver takes a step while bringing his body to the 2 kamaboko-type elastic material attached while holding the handle. By doing so, not the arm strength, but the pressure of the trunk or the foot portion of the portion hitting the kamaboko-type elastic material of the 2 is transmitted to the left and right skeleton parts of the 7 stroller through the kamaboko-type elastic material of the stroller. Move forward.
Speaking of kamaboko, the part that the plate is in contact with is the flat part of the kamaboko-type elastic material of 2 above, but when the driver moves forward, it comes into contact with the left and right skeleton parts of the 7 stroller, It is possible to generate and use power regardless of the length and thickness of the left and right widths of the left and right skeleton parts of the 7 stroller.
As a result, the power works on the skeleton part, so that not only a direct impact does not have to be applied to the baby, but the present invention uses the power generated by bringing the body forward, so the driver can use it rather than using his arms. It can generate great power to move forward with much less burden on the body.

12 is an elastic material in which the shape of the kamaboko-type elastic material of No. 2 is U-shaped.
The invention of FIG. 5 has the same principle and effect as Example 1, but only the shape is different.
Some strollers and wheelchairs have a reclining function on the backrest. However, in the second kamaboko-type elastic material of the first embodiment, when the reclining is tilted, the head of the person on board comes into contact with the second kamaboko-type elastic material.
In order to avoid this, a three-dimensional U-shape including a curved donut shape halved like a half moon was provided.
By using the U-shape, the 12 U-shaped elastic material that can be passed through without reclining the head even when the reclining is in a tilted state can be used.
As shown in FIG. 6, since the reclining function is originally designed at an angle where a driver's foot that runs while holding a steering wheel does not hit, the 12 U-shape is placed in the body of the driver and the range of movement of the foot. By installing the elastic material of the mold, the elastic material can be installed and used while reclining.

Next, different modes for carrying out the present invention shown in FIGS. 5, 7, and 8 will be described. In the description of the different modes for carrying out the present invention, the same components as those in the best embodiment 1 for carrying out the present invention are denoted by the same reference numerals, and redundant description is omitted.
Depending on the shape of the stroller, the right and left skeleton parts of the seven strollers, which are almost perpendicular to the ground, are largely inclined forward and backward, and the skeleton angles are various. For this reason, it is necessary to effectively transmit power to the contact portion even in such a stroller or wheelchair skeleton.
Therefore, as shown in FIG. 8, in order to maintain the 12 U-shaped elastic members in contact with the body in parallel and to transmit the force in parallel to the frame portion of the stroller or the wheelchair which is inclined, it is shown in FIG. 8. The above-mentioned 14 small elastic members for changing the tip angle, which is a small elastic material having an inclination attached to the tip or flat portion of the 12 U-shaped elastic materials. 13 is a hook-and-loop fastener for connecting a small elastic material for changing the tip angle at both ends of the 12 U-shaped elastic material, and 14 is a power supply for the 12 U-shaped elastic material and a stroller or wheelchair. It is a small elastic material for changing the tip angle for accurate transmission.
As a result, even when the stroller is reclining, the left and right framework parts of the stroller of 7 can be adapted to a stroller or a wheelchair having a shape that is not perpendicular to the ground, and the driver's power can be transmitted to the stroller or the wheelchair.

The wheelbarrow of the present invention, in particular, a stroller or a wheelchair aid can be mounted on various types of strollers and wheelchairs, and can be used for applications that greatly reduce the labor of the driver.
