DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings. 1 to 4, reference numeral 1 denotes an underground base of the present example, which is the thumb 2a, the four-finger part 2b, and the two-finger part 2a. The protruding pieces 3, 4, and 5 are integrally raised and formed at an appropriate height on the periphery of each part of the finger crotch portion 2c between the bases 2b. Upper 7 sewn with fabric on the lower surface of the end of
Is suspended or glued or sewn to the bottom 2 of the basement, and protective plates 8, 9, 10 which are curved along the outer surface shape of each protruding piece are attached to the outer surface of each protruding piece 3, 4, 5. It is formed by wearing.

The protruding pieces 3, 4, and 5 rise substantially vertically from the bottom surface 2d of the base 2 and the two fingers 2a and 2b are formed in an inverted U shape along the periphery of the base 2. The finger crotch portions 2c are each formed in a U-shape so as to be integrally formed with the bottom 2 at each basement. The height of each protruding piece is 2 when the protruding pieces 3 and 4 are underground.
18 mm or more from the lower surface of, preferably 20 to 25 mm,
The protruding piece 5 is slightly higher than the protruding pieces 3 and 4, and is formed to have a length of 25 mm or more. The thickness of each protruding piece is preferably at least about 3 to 7 mm, which is thicker than the guard plate. However, a sufficient cushioning action is provided between the fingertip and the guard plate, and the thickness of each protrusion piece does not hinder the movement of the fingertip. It can be selected within a suitable range.

As shown in FIG. 3, each of the protective plates 8, 9, 10 is made of an iron plate, a synthetic resin plate or another hard plate having a thickness of several millimeters, preferably about 2 to 6 mm. Outside of each protruding piece to match the outer surface shape of 3, 4, 5
It is formed to be curved along the surface . The height of each board is
The toe is safely protected against falling objects, and at the same time, is set so as not to disturb the wearer during wear, preferably about 10 to 15 mm.
It is set to be slightly higher than that.

[0010] The production of the underground basin 1 of this example is based on
And the protruding pieces 3, 4, and 5 are integrally formed, and an upper 7 is bonded or stitched to the bottom 2 of the basement. Further, protective plates 8, 9, and 10 are firmly attached to the outer surface of each protruding piece via an adhesive. This is performed by adhering and fixing to the surface. An adhesive 11 is poured into the contact portion of the upper 7 and adheres to the protruding pieces 3, 4, and 5,
It can be fixed (see FIG. 4).

Further, as shown in FIG.
Step 1 on which the protection plates 8, 9, 10 can be mounted on the outer surface of the step 5
2, or by forming a locking portion capable of locking the upper and lower ends of the protection plate, the protection plates 8, 9, and 10 are hardly detached, and the fixing property can be further improved.

In the basement 1 thus formed, the protective plates 8, 9, 10 are stably formed along the outer side surfaces of the protruding pieces 3, 4, 5 of both fingertips 2a, 2b and finger crotch 2c. When the heavy object falls to the fingertip during the operation, the fallen object is received at the upper end of each protection plate, and there is no fear that the impact is directly applied to the fingertip. In particular, since the protection plate 10 is also provided on the finger crotch portion 2c, even if a heavy object falls to a position closer to the ankle than the fingertip, this can be received by the protection plate 10 and damage to the toes can be prevented. Can be prevented. Moreover, even if a fingertip collides with a mounted object during walking, the protection plates 8 and 9 provided on the outer side surfaces of both fingertips 2a and 2b protect the fingertips on the wall surfaces of the both protection plates and protrude pieces 3 and 4. The shock can be mitigated through the contact and the fingertip can be protected.

Since each protection plate is provided along the outer surface of the protruding pieces 3, 4, and 5, the fingertips are not pressed by the respective protection plates during walking, and there is no danger of damaging the fingertips. The protruding pieces 3, 4, and 5 provide cushioning between each protective plate and the fingertips to ease the comfort, and at the same time secure the freedom of the fingertips, providing a good feeling of wearing, stability, and light workability. Can be obtained.

Further, compared with the conventional configuration in which the entire finger is covered first, the material used can be reduced and the weight can be reduced.
At the time of manufacture, each protective plate can be attached after bonding the upper 7 to the bottom 2 under the basement.
It is not necessary to perform any special processing on the product, the production is not troublesome, and the production cost can be suppressed.

[0015]

As described above, according to the underground of the present invention,
Since the protection plate is fixed to the finger crotch part, even if a heavy object falls to a position closer to the ankle than the fingertip, the protection plate can receive this and protect the toe safely. In addition, by providing a protection plate on the outer surface of both fingertips, if a heavy object falls on the fingertip, it can be received at the upper ends of both protection plates, and even if it collides with the mounted object during walking, The fingertips are protected by the wall surface, and at the same time, the projecting pieces at the edge of the basement absorb the impact at the time of the collision and can effectively prevent the fingertips from being damaged.

By interposing a protruding piece between the guard plate and the fingertip, the fingertip is prevented from being pressed by the guard plate, and there is no danger of damaging the fingertip. And a sense of stability and light workability are obtained.

Further, in the basement according to the present invention, since a protective plate is fixed only to the outer side surface of each protruding piece, materials used can be reduced and weight can be reduced as compared with the conventional configuration. Since the protective plate can be attached to the bottom of the basement after bonding, the protective plate can be easily manufactured according to the conventional processing steps, and the manufacturing cost can be reduced.
