Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above-described conventional technology, it is assumed that by using a combination of safety shoes and instep protectors, the toes and instep portions of the feet are protected from the fall of heavy objects. For this reason, for example, when performing work in construction such as breaking concrete using a breaker, even if an instep protector or the like is worn, there is a problem that the cutting edge of the breaker penetrates the instep protector or hits an ankle portion or the like not covered by the instep protector, and there is a risk of an accident in which the foot is injured.

[0006] The object of the present invention is to provide a foot protector for construction workers that can prevent accidents such as foot injuries from occurring when performing work such as breaking concrete using breakers. [Means for solving the problem]

[0007] The construction foot protector of the present invention is a construction foot protector composed of a plate-like body, having an inclined surface that slopes outwards from a ridge formed in the central part, and having a shape that gradually rises from the front end to the rear end, and having a toe and instep protection part that covers the toe and instep parts of the foot, and the rear end of the toe and instep protection part Continuously molded The footwear comprises an ankle and shin protection section having a semi-circular cross-sectional shape and extending upward from the toe and instep protection section, covering the ankle and shin portions of the foot, and fastening belts extending rearward from both ends of the ankle and shin protection section. The inclined surface includes a first inclined surface located on the front end side and inclined toward both sides from the ridge, a second inclined surface located on the rear end side and inclined toward both sides from the ridge, and a third inclined surface located midway between the first and second inclined surfaces and inclined toward both sides from the ridge, and the curved shape of the ridge is such that the angles become gentler in the order of the angle formed by the third inclined surface, the angle formed by the second inclined surface, and the angle formed by the first inclined surface. It is characterized by. [Effects of the Invention]

[0008] According to the construction foot protector of the present invention, it is possible to prevent accidents resulting in foot injuries even when performing work such as breaking concrete using breakers or the like. [Brief explanation of the drawing]

[Figure 2] Figure 1 is a schematic side view showing the overall configuration of the construction foot protector. [Figure 3] Figure 1 is a schematic front view showing the overall configuration of the construction foot protector. [Figure 4] Figure 1 shows a schematic bottom view and cross-sectional view illustrating the overall structure of the construction foot protector. [Modes for carrying out the invention]

[0010] The details of the present invention will be described below with reference to the drawings, including embodiments.

[0011] Figure 1 is a schematic perspective view showing the overall configuration of a construction foot protector according to an embodiment of the present invention, Figure 2 is a side view, Figure 3 is a front view, and Figure 4 is a bottom view. In these figures, curves are shown to represent the curved shape of the construction foot protector. Note that the fixing belt 130, which will be described later and shown in Figure 1, is not shown in Figures 2 to 4.

[0012] The construction foot protector 100 shown in Figure 1 is intended for use in construction work such as breaking concrete using a breaker, and is designed so that when the tip of the breaker blade strikes the surface of the construction foot protector 100, the blade will slide along the surface and will not pierce the construction foot protector 100, thus preventing the blade from penetrating and injuring the worker's foot.

[0013] The construction foot protector 100 is constructed by molding a plate-like body (for example, about 5 mm thick) made of resin, such as transparent polycarbonate, into a predetermined shape, and is shaped to cover the toes, instep, ankle, and shin. Specifically, as shown in Figure 2, it has a structure comprising a toe and instep protection section 110 provided at the front end to cover the toes and instep, and an ankle and shin protection section 120 provided continuously at the rear end of the toe and instep protection section 110 to cover the front half of the ankle and shin. Unlike conventional instep protectors, the toe and instep protection section 110 is designed to cover not only the instep but also the toes, and does not necessarily need to be used in combination with safety shoes.

[0014] Figure 4 is a bottom view of the construction foot protector 100, and the cross-sectional configurations of section AA, section BB, and section CC are shown on the right side. As shown in Figure 4, the toe and instep protection section 110 has a structure in which inclined surfaces 112a and 112b slope downward on both sides from a ridge section 111 (see Figure 1), which is a higher section provided in the approximate center along the rear end to the front end. Furthermore, as shown in Figure 2, the ridge section 111 has a sloped shape such that the rear end is higher and the front end is lower.

[0015] The angle α shown in Figure 2 of the toe and instep protection portion 110, where the rear end is higher and the front end is lower, is preferably in the range of 35° to 45°, and in this embodiment, it is about 40°. Furthermore, the angle β formed by the inclined surface 112a and the inclined surface 112b with respect to the ridge portion 111 shown in Figure 4, is preferably set so that the angle β at the steepest point (near the AA section in the example of Figure 4) is in the range of 60° to 70°, and in this embodiment, it is about 65°. In this embodiment, the angle β near the AA section is the steepest, followed by the angle near the BB section on the rear end, and then the angle near the CC section on the front end, in that order, resulting in a curved surface shape where the angles become gentler in that order.

[0016] Furthermore, as shown in Figure 2, the ankle and shin protection portion 120 is shaped to extend substantially vertically upward from the rear end of the toe and instep protection portion 110, and as shown in Figure 4, its cross-sectional shape is substantially semi-circular. As shown in Figure 1, a fixing belt 130 is provided on this ankle and shin protection portion 120. The fixing belt 130 is inserted into through holes provided on both ends of the ankle and shin protection portion 120 and secured therein.

[0017] Also, a cushion 140 is provided at the upper end of the ankle and shin protection part 120. This cushion 140 is for preventing the upper end part of the ankle and shin protection part 120 from hitting the shin and causing pain. The cushion 140 is fixed to the through holes provided on the upper side of the ankle and shin protection part 120 by assembly screws 121 or the like. The cushion 140 is composed of a cushion material such as flexible NBR (acrylonitrile butadiene rubber) and a cover or the like covering the surface of this cushion material.

[0018] Regarding the overall height h2 and the height h1 of the protector part of the construction foot protector 100 shown in FIG. 3, it is preferable to be within the following ranges. That is, for the height h1, it is preferably about 160 mm to 210 mm, and for the height h2, it is preferably about 180 to 230 mm. By setting it within this range, the foot including the ankle and shin can be protected, and wearing the construction foot protector 100 will not interfere with walking. That is, if the above dimensions are too short, the protection of the foot may not be sufficient, and if they are too long, it may interfere with walking.

[0019] The construction foot protector 100 of the present embodiment with the above configuration is, for example, worn over shoes, boots, etc. when performing work in construction such as breaking concrete using a breaker or the like, and is worn on the foot by winding the fixing belt 130 around the back side of the ankle (the part of the calf). Thereby, the toe and nail protection part 110 covers and protects the toe and nail parts of the foot, and the ankle and shin protection part 120 covers and protects the front and lateral parts of the ankle and shin.

[0020] In this state, if a breaker or the like is used, when the blade of the breaker hits the construction foot protector 100, due to its material and the curved shape of the surface, the blade slides on the surface of the construction foot protector 100 and does not bite into the construction foot protector 100. Therefore, the construction foot protector 100 cannot be penetrated, and it is possible to prevent the foot from being injured. In the case of a conventional instep protector made of an aluminum plate or the like, when the blade of the breaker hits it, there is a risk that the blade will bite in and penetrate the instep protector, injuring the foot.

[0021] Also, in the conventional instep protector, the blade of the breaker hitting the instep protector part may hit the foot from the ankle part not covered by the instep protector, and the foot may be injured. However, in the construction foot protector 100 of the present embodiment, the ankle and shin protection part 120, which is shaped to extend substantially vertically upward from the tip of the toe and the rear end side of the instep protection part 110, can surely prevent the blade of the breaker from hitting the ankle part or the like, and can prevent the foot from being injured.

[0022] As described above, the embodiments of the present invention have been explained. However, this embodiment is shown as an example, and it can be implemented in various other forms. Without departing from the gist of the invention, components can be omitted, replaced, or changed.
