Description

The present invention relates to shoes and a cane.

There was the following prior art.
As a prior art, there is my patent shown in FIG. 5 (Patent Publication 2001-286383, a shoe detacher / cane and a shoehorn used for the shoe detacher / cane), which has a weak grip that does not produce a force to grip the hand lever. By tilting the cane, a person can grab the shoe by the lever principle between the shoehorn and the cane (rod-like object) and move it and put it on as it is. The optional product with a ring (5) that allows the arm to pass over the cane, as shown in Fig. 2, allows the person who has lost the tip of the wrist to pass the arm through the ring, grab the shoe, move it, and wear it. It was very pleased to those who have. In this optional product, the end of the handle (6) is covered with the rubber band (8), the friction coefficient is increased, and the rubber band at the lower end of the handle is put on the shoebox top plate (7) and hooked. So, I put my wrist in a state where I can put it in and out, and I put it in a state where it is easy to use the shoe attachment / cane.

Today, I think that the biggest issue for society is the creation of industrial jobs that are vital to people with minimal environmental impact. The world is full of unsolvable incidents such as terrorism, fraud, bullying, murder, etc., most of the victims cry and fall asleep, and even if the cause is criminal punishment, there are rare cases where the victim is compensated to civil liability It is. This is the reality of the legal society. The society was swayed by new technologies, and those who could not keep up with technological evolution became a disparity society that could not survive unless they violated the law. Counterfeiting of structural statements of buildings, counterfeiting of cushion rubber used for seismic isolation structures, counterfeiting of piled-up data, large companies of counterfeiting accounting documents, excessive discounts on bus companies, resale of waste food, age caused by price competition Black companies, incidents, accidents, etc. caused by harsh labor regardless. If there is a chance, a fiercely competitive society that will soon be crushed. Just over a decade ago, companies that were major LCDs and solar power generation and power companies that had no competitors survived. I think one of the solutions to the problems caused by these factors is to create a new job. If there are jobs that can be tackled enthusiastically and there is no unemployment, I think the problems will be drastically reduced. In the past, Nishijin Ori protected the employment of many craftsmen. Although it was expensive, it was the property of the house used by parents, children, and grandchildren. In the era when deregulation has accelerated and there are no barriers to industries, capital is concentrated like ants flock to what is called money games, competitors increase at a stretch, and in an industry that does not make money quickly It will be formed. The end of the process is restructuring, bankruptcy, and out of business. In the past, there have been cases where large amounts of taxes have been invested. Low-cost supremacy has become a very difficult era, which is a waste reserve army, including goods containers, and expells large quantities of disposable goods and goods that become garbage immediately, which barely supports industry and employment. . There are a lot of cheap products that are not subject to recycling laws, and cheap, waste reserve armies. The well-known temporary storage area, which does not know how to dispose of it, is turned into a garbage storage area, and human beings are drowning in the large sea of waste that has no place to go. Those who can't get married at work, who can't get married, are not just young people, they are full of jealousy, those who are eager to hit the place of stress, those who are motivated and confined in the room empty, etc. Drift. In order to solve these problems, we believe that development of non-disposable, industrial and product products is indispensable, and one citizen continues to apply for patents.

The present invention is an improvement over the prior invention. The invention is called Parkinson's disease, a muscular strength is steadily decreasing, and an encounter with a person who cannot stand up by himself when he sits down. A tool for grasping shoes while standing (Patent Publication 2001-286383, Shoe Detachable Tool / Cane) And a shoehorn used for the shoe attaching / detaching tool / cane). It was an easy-to-understand and easy-to-use item for the elderly, with no mechanically movable parts, but the shoes could be gripped when worn. From the experience of making handmade products and selling them on the street, it was found that in the present invention, it is impossible to grasp the shoe with the heel-back shape of the shoe shown in FIG. Observing the situation, if the shape of the rear part of the shoe is almost vertical, as shown in FIG. 5, the lower end of the cane (2) contacts the rear surface of the lower part of the shoe and pushes the lower part of the shoe forward. The shoes could be lifted by the contact frictional force, but in the case where the bottom shape of the shoe was widened at the bottom of the shoe, the contact surface was inclined, so the pressing force against the contact surface was dispersed and escaped. The force that works at right angles also became smaller, and the contact point slipped and could not be lifted.

Also, shoes made of a material with a slippery contact surface could not be lifted by frictional force. In other words, when picking food red beans with chopsticks, if the chopsticks are in contact with the surface of the red beans at a right angle, it can be grasped, but if it hits a slightly slanted surface, it is the same principle as not picking up. This is because the force applied from the oblique direction is dispersed in the direction perpendicular to the surface and in the parallel direction compared to the force applied from the direction perpendicular to the surface. The force applied to the slope, which is the principle of the force according to the trigonometric function, is distributed in the perpendicular direction and the parallel direction according to the angle, the force also works in the parallel direction, the frictional force decreases, and it slides. . In addition, there is a feature that the shoes cannot be gripped even when the friction is small or not, such as when the contact surface is wet. It was the limit of the idea of lifting with frictional force.

Furthermore, in the case of lace shoes, cloth and leather face plates are attached to the instep. In Patent Document 1 in which a shoe is worn by gripping a shoe heel, there is a disadvantage in that it slips into the inside together with the foot worn by this belo.

Therefore, as shown in FIG. 7, the present invention is provided with a protruding portion (3) that enters the lower end of the cane (2) in the direction between the lower end of the shoe heel and the floor (ground). When the protruding portion (3) entered between the sole and the floor, the shoe could be lifted upward from the sole, and the shoe could be lifted even without friction.

When the upper part of the cane is tilted backwards with the shoehorn and the cane straddling the shoe heel, the contact point between the shoehorn and the upper inner surface of the shoestick is the fulcrum, the upper part of the cane is the force point, and the contact point between the protruding part and the lower end of the shoestick acts The tip of the protruding part (3) enters the sole according to the principle of leverage, and when the cane is lifted in this state, the sole is lifted from the bottom up, so that the shoe can be grasped and lifted. Bring it to any position, place it on the floor, put your foot into the shoe, slide along the shoehorn, and the foot will slip into the shoe.

When removing the shoehorn, tilt the upper part of the cane forward, the heel of the foot inside the shoe will be the fulcrum, the protruding part (3) will move backward and away from the rear surface of the shoeclaw. The shoehorn comes off the shoe.

As described above, the present invention solves the above-mentioned problems. In other words, it was possible to lift even shoes that could not be lifted by the conventional way of thinking.

FIG. 3 is a perspective view and a side view of an embodiment in which a protrusion (3) is provided on the entire outer periphery of the lower end of the stone protrusion (4). This will increase the stone floor area and allow the cane (2) to stand on its own.

FIG. 3 also shows an example in which the shoehorn (1) can be retrofitted. The shoehorn is made of resin, an elastic material, so that it can be attached to an existing cane so that it can be fitted to the outer diameter of the cane. After fitting, tighten with screws and nuts (9) and fix to the cane. If the force of fitting is strong, a shoehorn is attached to the cane without the need for a screw nut. At this time, by providing a part with a high friction coefficient such as rubber in the fitting contact portion, it is possible to make the fitting difficult to move. As shown in FIG. 8 of the prior application patent document of Reference 1, there are various existing methods and techniques such as screwing and bonding, as shown in FIG.

FIG. 4 is a perspective view showing an embodiment in which a protrusion (3) is provided on a pedestal (10) provided at the lower end of the cane (2). The center of the cane (2) is brought to an eccentric position instead of the center of the base.
By turning the stone tip (4), it is possible to handle various shapes and sizes of shoes. The figure can be gripped with the conventional frictional force as it is, and the shoe (4) is turned to the shoes that cannot be gripped with the frictional force, and the shoe sole is lifted by bringing the protruding part (3) to the shoehorn. You can grab your shoes. The cane can be made independent by the presence of the pedestal (10). As the pedestal (4) is turned, the pedestal connected to it also rotates and the center of the cane (2) is located in an eccentric position. Can handle various shoe sizes and shapes. In this plan, the stone bump (4), the pedestal (10), and the protruding portion (3) are integrally molded. However, it may be integrated by a technique such as bonding to integrate the separated parts. .

Further, in the case of shoes with tongue, the protrusion (3) shown in FIG. 1 is placed in the upper of the shoe, and the foot is lifted from below the tongue at the tip of the protrusion (3). After that, the protruding part (3) was once extracted, and a shoehorn was inserted in the rear of the toes, so that the shoes could be put on without shifting the tongue.

This invention is an invention in which the shoehorn (1), the cane (2), and the protruding portion (3) are integrated to exert an effect. In today's highly advanced manufacturing technology, it is easy to partially manufacture them. If you sell them individually and the customers you buy integrate, you don't have patent rights.
Therefore, the claims are written in a way that extends to each part. We believe that this is the only way to protect people's livelihood and not to increase the number of inexpensive products that do not increase waste. I think that is also the purpose of patent law. The copyright was noticed in the Olympic emblem issue. It seems that the patent rights are 50 years after death, while the patent rights are 20 years after filing. It is undeniable that there is a difference in the level of content for any right, but without any examination, what becomes a powerful right feels a threat in a time when it is in the world. In order to sell things, they cannot sell unless the goodness is communicated to customers. It requires public relations and publicity, but it takes enormous energy and money to actually do this. Personal property is not something that can be used. The invention of Document 1 has also invested enormous energy, such as selling to companies and selling stalls. As a salaried worker, you may not know, but even if a product that takes two days to produce is sold in a stall for a day, there are almost no days when you cannot sell one. There are also harassment of street vendor sales and battles with people who enforce traditional rights such as Shoba. Since there is no trust, it is difficult to guide customers even if they have a store that cannot sell unless it is less than the cost. That's why I started with street vendors. Tomorrow I feel homeless, but the past 15 years have passed. 20 years are short to penetrate the world. Perhaps it is not something that an individual who has no salary, such as an invention, does. However, the experience that made me realize how happy the five bodies are in the welfare world is what supports me now.

The perspective view which shows the state which provided the protrusion part (3) in the lower end of a cane (2). The perspective view explaining the state which provided the ring (5) in the upper end of the cane (2). The perspective view and side view of an Example which provided the protrusion part (3) in all the outer periphery of a stone protrusion (4). The perspective view which shows the Example which provided the protrusion part (3) in the base (10) provided in the lower end of the cane (2). Side surface sectional drawing explaining the state which lifts shoes of patent document 1. FIG. Explanatory drawing showing a mode that the technique of patent document 1 cannot grasp the heel-spreaded heel shoes. Side surface sectional drawing of this invention which provided the protrusion part (3) in the lower end of the cane (2). The Example figure which provided the protrusion part (3) in the designed shoehorn.

 As shown in FIG. 1, in reality, most canes in circulation in the world have rubber caps called stone bumps (4). The objective effect can be achieved by providing a protruding portion (3) in the direction of the lower shoehorn of the stone bump. Of course, even with a cane that is a stick without a rubber bump, the target effect can be achieved by providing a protrusion (3) at the lower end of the cane. For example, even if it is just a stick without a rubber cap bumper, the end of a five-yen coin washer protrudes from the outer surface of the cane to the outside at the bottom of the stick in a state that protrudes about 5 mm. By screwing the screw from the hole toward the rod, the shoe wearer / cane of the present invention having the protrusion (3) on the bottom of the cane is completed.

FIG. 3 is a perspective view and a side view of an embodiment in which a protrusion is provided on the entire outer peripheral surface of the lower end of the stone protrusion (4). This will increase the stone floor area and allow the cane (2) to stand on its own.

FIG. 3 also shows an example in which a shoehorn can be retrofitted. The shoehorn is made of resin, an elastic material, so that it can be attached to an existing cane so that it can be fitted to the outer diameter of the cane. After fitting, tighten with screws and nuts (9) and fix to the cane. As shown in FIG. 8 of the prior application patent in Document 1, there are various methods and techniques such as fitting, band tightening, screwing, and adhesion as shown in FIG.

FIG. 4 is a perspective view showing an embodiment in which a protrusion (3) is provided on a pedestal (10) provided at the lower end of the cane (2). The center of the cane (2) is brought to an eccentric position instead of the center of the base.
By turning the stone tip (4), it is possible to handle various shapes and sizes of shoes. The figure can be gripped with the conventional frictional force as it is, and the shoe (4) is turned to the shoes that cannot be gripped with the frictional force, and the shoe sole is lifted by bringing the protruding part (3) to the shoehorn. You can grab your shoes. The cane can be made independent by the presence of the pedestal (10). Since the center of the cane (2) is in an eccentric position when the pedestal is turned, the distance between the shoehorn (1) and the side surface of the pedestal (10) changes depending on the turning position, so that various shoes can be handled.

With the declining birthrate and aging society, the number of elderly people will increase, and the industries that are worthwhile for young people will be exposed to international competition with low wages. Creation of industries that are the worth of people's lives, with minimal environmental impact, is essential. As a universally designed shoehorn that is convenient for everyone, regardless of age, it can be sent to the world.

The present invention is realized by combining three points of the cane (2), the shoehorn (1), and the protruding portion (3). Many companies today have manufacturing technology and production facilities. There are many companies that can easily make this invention. If the company produces and sells the three items separately, and the customer assembles the three items by themselves, the patent right will not reach. This is far from my philosophy of creating an employment industry that is not exposed to price competition. Therefore, a claim is written so that the present invention extends to the above three parts which are assembled into the present invention as a finished product.

1, shoehorn 2, cane 3, protrusion 4, stone protrusion 5, ring 6, handle 7, shoebox top plate 8, rubber band 9, screw, nut 10, pedestal 11, heel spreading
