DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to safety shoes used to protect workers' toes and insteps from falling objects in factories and civil engineering work sites.

[0002]

2. Description of the Related Art Conventional safety shoes are commonly used in factories and civil engineering construction sites in order to protect workers' toes and insteps from falling objects by using a core material made of a steel plate or the like that covers the toes. And leather shoes fixed to the artificial leather shoe body, and were strong and heavy.

In the example disclosed in Japanese Patent Application Laid-Open No. 9-187304, a core material storage portion having an opening through which a core material can be inserted from the rear and a gap capable of storing the core material is provided on the toe surface of the instep portion. When there is a risk of falling objects, insert the core material through the opening into the gap that is the core material storage part to protect the workers' toes and insteps from falling objects, and conversely, the risk of falling objects In some cases, the core material can be removed when moving around a wide range or moving over a long distance without using the core.

In the example disclosed in Japanese Patent Application Laid-Open No. 11-28102, the upper part of the toe is bent from the tip of the shoe sole on the toe side of the breathable shoe body to the side of the rising foot. A hard toe protector to cover while isolating, and a hard toe to cover while isolating the upper part of the insole, spanning between the left and right sides of the sole on the instep side A protector is provided between the protector for the instep portion and the protector for the toe portion.

[0005]

However, in the structure of conventional general safety shoes, since a core member made of a strong steel plate or the like is fixed to the shoe main body, the worker is not subjected to impact or pressure from a falling object. It is safe because it protects your toes and instep, but it is hard and heavy, so it is hard to bend, walking and working, when walking or working, your feet are strained, your feet are tired easily, and your instep is painful And there were problems such as the legs becoming numb.

In the example disclosed in Japanese Patent Application Laid-Open No. 9-187304, there is no danger of falling objects, and when moving around a wide area or traveling a long distance, the foot becomes easily bent by removing the core material. It reduces the burden and fatigue of the foot, reduces the pain of the instep and the numbness of the toes, but it can also be lost by removing the core material. If the core material cannot be inserted into the core material storage portion through the opening because the material cannot be found, or if the operator forgets to insert the core material, there is a problem that the toes and the instep of the operator cannot be protected from falling objects.

In the example disclosed in Japanese Patent Application Laid-Open No. H11-28102, while the inside of the shoe is provided with air permeability so as not to get stuffy,
In the work where there is a danger of falling objects, the toe and toe protectors can protect the workers' toes and instep from falling objects to some extent, and the flexible instep can be folded when walking. It becomes a bent part of the part and it can reduce the hindrance of walking, but since the protector for the instep and the protector for the toe open, the fallen object hits the instep and the worker's instep can not be protected There is a problem that there is a fear that the number of parts is large and the cost is high due to a complicated configuration.

Accordingly, the present invention is to provide a safety shoe which has a simple structure, protects a worker's toes and an instep from falling objects, and can easily bend and stretch an ankle during use. Aim.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a safety shoe comprising a sole and an epithelium and a toe protector provided on the toe of the epithelium. A hinge is formed near the distal end side of the protector, and the instep protector is rotatably mounted on the fulcrum of the hinge and is covered at a predetermined gap on the instep of the epithelium. The toe protector was made of a stainless steel plate, a steel plate, or a material having a strength equal to or higher than these, in order to protect the worker's toes and instep from falling objects.

With the above configuration, both the toe protector and the instep protector made of a durable stainless steel plate or a steel plate cover the toe from the toe, and the boundary between the toe protector and the instep protector is Even if the instep protector rotates back and forth around the hinge fulcrum, there is no gap, the strength is secured, and the worker's toes and instep can be reliably protected from the impact and pressure caused by falling objects. At the same time, do not press strongly on the toe protector or the upper surface of the epithelium and do not compress the foot.

The length of the instep protector is set to a predetermined size so as to wrap around the toe protector even if it is rotated back and forth about the fulcrum of the hinge, and the lower surface of the upper part of the instep protector is front and rear. When the front edge and the rear edge are bent upward so that the top surface of the toe protector and epithelium are not strongly pressed when turning, the strength is secured,
The toe and the instep of the worker are more reliably protected from the impact and the compression by the falling object, and the edge of the instep protector does not hit the toe or the instep of the worker during work or walking.

When a stopper is formed on the opposite side of the toe (rear end) of the hinge to stop the rotation by contacting the lower end of the instep protector. The lower surface of the upper part does not strongly press the upper surface of the epithelium, and does not compress the instep during work or walking.

The length of the toe protector is as short as 1/4 to 1/2 of the entire length of the instep of the epithelium from the tip, and the length of the instep protector covers the instep of the epithelium and the fulcrum of the hinge. The toe protector has a predetermined size such that it wraps with the toe protector even if it is rotated back and forth as an axis, and has a length that covers one-third to one-half of the entire length of the epithelium at the anti-toe side of the epithelium. The length of the instep protector is shorter than that of the conventional safety shoes, the instep protector is separated by a predetermined gap in the instep of the epithelium, and is pivotally mounted on the hinge fulcrum. There is no problem in bending the part, and even when the instep hits the instep protector, the instep protector rotates back and forth and does not compress the foot, and the ankle in use can be easily bent and stretched.

The toe protector 4 and the instep protector 5 are made of a stainless steel plate, a steel plate, or a material having a strength equal to or higher than these in order to protect the worker's toes and instep from falling objects.

In conventional safety shoes, the length of the toe protector 4 must cover about one-third of the entire length of the shoe body 1 from the tip of the shoe body 1 in order to protect the shoe sole 1 from the toe. However, in this embodiment, since both the toe protector 4 and the instep protector 5 protect from the toe to the instep, it may be shorter than conventional safety shoes. 1/6 to 1 / of total length of main body 1
And 4.

The length of the instep protector 5 is equal to that of the epithelium 2.
Of the epithelium 2 on the anti-toe (rear end) side instep of the epithelium 2 so as to cover the instep of the epithelium 2 so as to cover the instep of the epithelium 2 even if it rotates back and forth around the fulcrum 7 of the hinge 6 as an axis. The length of the toe cover is set to cover 1/3 to 1/2 of the total instep length of the instep 2, and when the instep protector 5 is rotated back and forth as indicated by the arrow, the toe protector is provided on the lower surface of the upper part of the instep protector 5. The upper and lower edges of the instep protector 5 are warped upward so that the upper surface of the instep 4 and the epithelium 2 are not strongly pressed, and the instep protector 5 is placed on the anti-toe (rear end) side of the hinge 6. A stopper 6a is formed to stop the rotation by abutment with the lower end of the.

The toe protector 4 has an upper surface on which the epithelium 2
May be covered with the instep, or coated with natural leather or synthetic leather separately from the epithelium 2, or may be painted aesthetically. Also, the instep protector 5 may be one whose upper surface is coated with natural leather or synthetic leather, or one which is aesthetically painted.

Next, the operation of this embodiment having the above configuration will be described. Cover from the toe to the instep with both the toe protector 4 and the instep protector 5 made of a durable stainless steel plate, steel plate, etc., and the toe protector 4

Since the leading edge and the trailing edge are warped upward, they do not strongly press the toe protector 4 or the upper surface of the epithelium 2 when rotated back and forth as indicated by the arrows.

Further, a stopper 6a is formed on the opposite side of the toe (rear end) of the hinge 6 to stop the rotation by abutment with the lower end of the instep protector 5, so that the instep protector 5 is rotated back and forth. Then, the upper surface of the epithelium is not strongly pressed by the lower surface of the upper part of the instep protector 5, so that the instep is not pressed during work or walking.

In addition, since the length of the toe protector 4 is shorter than that of the conventional safety shoes, the instep protector 5 is separated from the upper part of the epithelium 2 by a predetermined gap G, and the hinge 6
Is pivotally mounted on the fulcrum 7 so that there is no hindrance for the worker to bend the instep during walking. Even if the instep hits the instep protector 5, the instep protector 5 can be moved forward and backward. The foot does not hurt because it rotates and does not compress the foot, the ankle during use is easily bent and stretched, and the walking property is excellent.

[0022]

According to the present invention, in a safety shoe comprising a sole and an epithelium and a toe protector provided on the toe of the epithelium, a hinge is formed on the left and right sides of the sole near the opposite end of the toe protector, The instep protector is rotatably mounted on the fulcrum of the hinge, and is covered on the instep of the epithelium with a predetermined gap. The instep protector and the toe protector are provided to prevent the fallen object from the toe or foot of the worker. To protect the instep, it is made of stainless steel plate, steel plate or a material having strength equal to or higher than these, so that the strength is secured and the toes and instep of the worker are protected from impact and compression by falling objects It is possible to provide safety shoes which are excellent in safety, do not compress the foot during work or walking and do not hurt the foot.

Further, the length of the instep protector is set to a predetermined size so as to wrap with the toe protector even if it is rotated back and forth around the fulcrum of the hinge, and the lower surface of the upper part of the instep protector is front and rear. The front edge and the rear edge are bent upward so that the top of the toe protector and epithelium are not strongly pressed when pivoted, ensuring the strength and ensuring the worker's toes and feet from impact and pressure from falling objects. It is possible to provide safety shoes that can more reliably protect the instep and are excellent in safety, and that do not hit the edges during work or walking and do not hurt the feet.

Further, since a stopper is formed on the opposite side of the toe (rear end) of the hinge to abut against the lower end of the instep protector to stop the rotation, the instep protector is rotated when the instep protector is rotated back and forth. The upper surface of the upper part does not strongly press the upper surface of the epithelium, so that it is possible to provide a safety shoe that does not compress the instep during work or walking and does not hurt the foot.

The length of the tip protector is 1/4 to 1/2 the total length of the epithelium from the tip to be shorter than that of conventional safety shoes, and the length of the instep protector covers the epithelium of the epithelium. At the same time, in order to have a predetermined size such that it wraps around the toe protector even when it is rotated back and forth around the fulcrum of the hinge, it is 1/3 to 1/3 of the total length of the upper part of the epithelium at the anti-toe side part of the epithelium.
/ 2, the length of the toe protector is shorter than that of conventional safety shoes, and the instep protector is separated from the epithelium by a predetermined gap and pivots around the hinge fulcrum. Because it is freely attached to the shaft, it does not hinder the worker from bending the instep when walking, and even if the instep hits the instep protector, the instep protector turns back and forth and does not compress the foot It is possible to provide a safety shoe that does not hurt the foot, easily bends and stretches the ankle during use, and has excellent walking properties.
