Abstract

To develop a carry bag having a function of a walker for supporting safe walking, when an older person goes out on business such as shopping.SOLUTION: A carry bag has a function of a walker in which, a wheel diameter has a size capable of getting easily over a joint of a visually impaired person guide block or a stone pavement or over a step on a general road surface such as a railroad crossing, and a flywheel is rotated by transferring rotation of a rear wheel, to thereby facilitate getting over the step by its inertia, and to improve straightness and uprightness by a gyro effect of the flywheel.SELECTED DRAWING: Figure 1

Description

Technology for walkers for the elderly

With a conventional walker, unnecessary effort may be imposed on the user when the wheel diameter is insufficient to overcome the bump on the road surface. May be. In addition, a general carry bag uses a free-type caster in which all four wheels independently rotate in the direction of travel, which impairs straightness and allows elderly people to walk while supporting their bodies with carry handles. It is dangerous to fall as a vessel because of the possibility of falling.

Not applicable

Develop a carry bag with a walker function that supports safe walking when elderly people go out for shopping or other purposes.

The diameter of the wheels is large enough to easily cross the steps of general road surfaces such as guide blocks for blind and cobblestone joints, level crossings, etc., and transmits the rotation of the rear wheels to rotate the flywheel. Provided is a carry bag having a function as a walker, in which a step is easily overcome by inertia and a gyro effect of a flywheel improves straightness and uprightness.

The present invention combines the functions of a walker and a carry bag especially for the elderly, and supports walking and carrying luggage when going out for shopping or other purposes, and since one hand can be used freely, an escalator etc. You can hold the body by grasping the handrail when using.

Overall view Brake operation Flywheel and step Example of use

The present invention accumulates rotational energy in a flywheel during normal walking, makes it easier to cross a step on a general road surface by the inertia due to the energy, and stabilizes upright and straight running by the gyro effect of the flywheel. It is a carry bag with the function of a walker with improved characteristics.

FIG. 1 shows an overall view. The front wheel 111 is a free caster whose traveling direction can be turned and freely directed in the walking direction of the user, and the rear wheel 101 is provided with a first pulley 102 in which left and right wheels are connected by a single rear wheel shaft 108. The rotation of the rear wheel 101 is transmitted to the second pulley 104 via the belt 103 to rotate the flywheel 105.

The first pulley 102 and the second pulley 104 are prepared by the manufacturer in three different diameters, are interchangeable, have a replaceable structure, and have a diameter ratio of 1: 1 according to the user's request. , 1: 1.5, 1.5: 1 can be selected. The number of rotations of the flywheel 105 with respect to the rotation of the rear wheel 101 is selected, and the carry bag upright stability, straight running stability, and walking support are selected. Can be selected.

Reference numeral 116 denotes a flywheel cover that covers around the flywheel. Reference numeral 110 denotes a rear cover that covers bearings, pulleys, and belts of the rear wheel, both of which are designed to prevent user's clothes from being caught. The bag 114 used for storing luggage is made of a soft plastic material, and the height of the carry handle 117 can be freely adjusted according to the user's body type.

The brake lever 120 is depressed when the user grips the handle grip 118, and the brake shoe 106 that has been pressing the flywheel 105 via the brake wire 119 is released to release the braking of the rear wheel. When the user stops walking, moving the grip of the handle grip 118 causes the brake lever 120 to return and brake the rear wheel 101. This brake is effective when a carry bag left on an inclined walking surface such as a platform at a train station may move.

The brake wire guide 121 is a partition plate that prevents the brake wire 119 from being entangled with the brake spring 107, the brake shoe 106, and the flywheel 105 when the carry handle 117 is expanded and contracted.

FIG. 2 shows the brake operation. FIG. 2-1 shows a state in which the brake pedal 202 is not operated, and the brake shoe 205 is pressed against the flywheel 206 by the brake spring 204 to brake the rear wheel. FIG. 2-2 shows a state of walking, in which the brake lever 202 is operated, the brake shoe 205 is separated from the flywheel 206, and the braking of the rear wheel is released.

FIG. 2-3 shows details of the brake operation. The brake rod A · 208 is for easily operating the brake lever 202 with a weak gripping force of an elderly user by applying the principle of leverage. When the brake lever 202 is depressed, the inner wire 210 inside the brake wire 203 is pulled, the brake rod A / 208 rotates clockwise, the brake rod B / 209 moves to the left, and the brake spring 204 moves to the flywheel 206. The brake shoe 205 pressed and braking the rear wheel separates from the flywheel 206 and the braking is released.

FIG. 3-1 shows details of the flywheel. The shape is such that the weight is reduced by the lightening hole 303 and the outer peripheral portion 302 is made thicker to increase the moment of inertia, and iron is used as a material in principle, but is not limited to this.

FIG. 3B illustrates a state in which the wheels of the carry bag cross a general step on the road surface. The wheel 306 of a general carry bag has a small diameter in many cases, in particular, it is difficult to overcome a convex step. However, the wheel 305 having a relatively large diameter of the present invention easily exceeds the step due to the synergistic effect with the flywheel described above. be able to.

FIG. 4 shows a usage example. Since the height of the carry handle can be adjusted according to the user's body type, it is preferable to select a position where the body is easy to support and the brake lever is easy to operate.

As described in detail in the above-mentioned "Embodiment for carrying out the invention", the device has a function as a walker that has good straightness and uprightness and is easy to cross a step on a road surface in order to assist the walking of the elderly. Implemented as a carry bag.

Various support products have been developed against the background of the inadequate development of an environment for supporting the life of the elderly. The present invention is one of them, and commercialization oriented to the market, which is expected to expand in the future, is expected.
