Description

  The present invention relates to a protective cap with a disaster prevention surface provided with a shield covering the entire face.

For safety reasons, workers usually wear helmets (protective caps) where there is a risk of falling or flying objects or falling. In order to protect the face from flying objects during construction, construction, and civil engineering work, arcs (electrical discharge) or flying objects are generated when the electrodes are short-circuited during electrical installations, etc. In addition, a shield (disaster prevention surface) member is required for the helmet to be worn.
Conventionally, there has been a helmet in which a face shield is attached to a helmet so as to be freely opened and closed, and the face is protected as necessary. However, the helmet is a mechanism that rotates the face shield around the support shaft, and since the face shield is provided exposed on the surface of the main body, it not only looks bad, but also on the helmet surface. There is a problem that things may get caught and lack safety.
Therefore, Patent Document 1 below discloses a helmet in which the front of the helmet shell has a double shell structure and the face shield is housed in the storage space. According to this helmet, the face shield can be opened and closed smoothly, and high structural strength and safety can be ensured.

  However, in the helmet of the above-mentioned patent document 1, in order to accommodate the face shield, the frontal head surface of the shell is covered with a top cover to form a double shell structure. Since the face shield is stored in the storage space as it is, the helmet itself has a large shape.

  Therefore, the present invention has been made in view of such circumstances, and the protective cap (helmet) itself maintains a conventional size and accommodates a disaster prevention surface capable of shielding the entire face in the protective cap. The purpose is to provide a protective cap with a disaster prevention surface.

In order to solve the above-mentioned problems, the invention of the protective cap with a disaster prevention surface according to claim 1 is characterized in that the storage guide member for storing the disaster prevention surface for protecting the worker's face in the cap body includes the cap body and the cap body. In the protective cap with disaster prevention surface fixed to the hammock attached to
The disaster prevention surface is composed of a first shield member disposed on the side close to the face and a second shield member disposed on the far side,
The first shield member is locked to a storage guide hole formed in the storage guide member via a guide locking member, and is slidable in the vertical direction of the face along the storage guide hole. Move from the position stored in the body to the position covering the top of the face,
The second shield member is locked to a first slide hole formed in the first shield member via a slide locking member, and is slidable in the vertical direction of the face along the first slide hole. The same slide locking member is locked in the second slide hole formed in the second shield member, and the slide locking member can slide in the vertical direction of the face along the second slide hole. Is moved to a position covering the lower part of the face from a position overlapping the first shield member,
The disaster prevention surface is stored in a space between the cap body and the storage guide member in a state where both shield members are overlapped, and covers the entire face by covering the upper and lower portions of the face with both shield members, respectively. It is comprised by these.

The disaster prevention surface is a shield surface that can cover the entire face of the worker, and is composed of a plurality of shield members. Further, the disaster prevention surface is configured to be housed in the cap body, and at the time of housing, the plurality of shield members are housed in the cap body in a state of overlapping each other.
The storage guide member is a thin plate-like member made of, for example, a synthetic resin, which is disposed on both sides from the inner front portion of the cap body (shell). A shock absorbing hammock is attached to the cap body, and the storage guide member is disposed between the cap body and the hammock. When an impact absorbing liner is provided, it is disposed between the storage guide and the hammock. Both sides of the storage guide member are fixed to the inner wall of the cap body, and the front part is fixed to the hammock (the fixing of both sides may be fixed to the inner wall of the cap body together with the hammock). Thereby, a gap is formed between the inner wall of the cap body and the surface of the storage guide member in the inner front portion of the cap body, and this clearance stores the disaster prevention surface (the first shield member and the second shield member). Storage space.

  In the storage guide member, a storage guide hole for guiding the disaster prevention surface into the cap body is formed from the opening edge of the cap body toward the inside (cap body ceiling). The storage guide hole has a long hole shape, and a plurality of storage guide holes are formed. A first shield member is engaged with the storage guide hole via a guide locking member, and the first shield member slides along the storage guide hole and can move in the vertical direction of the face. The first shield member is made of a substantially strip-shaped synthetic resin having a curvature corresponding to the curved surfaces in the left-right direction and the up-down direction of the face. When the first shield member slides upward, the first shield member moves to a position where it overlaps the storage guide member, and is stored in the cap body in a state where it overlaps the front side of the storage guide member. On the other hand, when sliding downward, a slight portion of the lower portion of the storage guide member and the upper portion of the first shield member moves to a position where the left and right belt-like portions overlap each other, covering the operator's eyes and nose, It is arranged so as to cover the upper part of the face.

  On both the left and right sides of the first shield member and the second shield member, elongated hole-shaped slide holes (first slide hole and second slide hole) extending in the vertical direction of the face are formed. One common slide locking member is engaged with these slide holes, the first shield member is disposed on the back side of the locking member, and the second shield member is disposed on the front side. The second shield member slides along the first slide hole of the first shield member together with the locking member, and is movable in the vertical direction of the face. Further, the second shield member slides in the direction of the second slide hole formed in the second shield member with respect to the slide locking member, and is similarly movable in the vertical direction of the face. The second shield member is made of a substantially strip-shaped synthetic resin or the like having a curvature corresponding to the curved surfaces in the left-right direction and the up-down direction of the face. The second shield member slides to the uppermost portion along the first slide hole, and moves to a position overlapping with the first shield member when slid to the uppermost portion with respect to the slide locking member. It is arrange | positioned at the front side. On the other hand, when it slides to the lowest part along the first slide hole and slides to the lowest part with respect to the slide locking member, the lower part of the first shield member and the slight part of the upper part of the second shield member are left and right. It moves to the position where it overlaps with the direction belt-shaped part, and is arranged in a state covering the operator's mouth and throat, that is, covering the lower part of the face.

In order to solve the above-mentioned problem, the invention according to claim 2 is the protective cap with a disaster prevention surface according to claim 1, wherein the first shield member and the second shield member are formed of a cubic curved surface having the same curvature. ,
The first slide hole and the second slide hole are formed on the left and right sides of the first shield member and the second shield member according to the curvature of the cubic curved shield in the vertical direction of the face,
The slide locking member is fitted to the slider from the inside of the first shield member through the first slide hole, and the slider disposed between the first shield member and the second shield member. A first holder and a second holder that is fitted to the slider from the outside of the second shield member through the second slide hole;
A gap corresponding to the thickness of the slider is formed between the front surface of the first shield member and the back surface of the second shield member.

  The two shield members constituting the disaster prevention surface are each composed of a cubic curved surface member having a curvature corresponding to the curved surface of the face (the laterally curved surface and the vertically curved surface). The slide holes formed in the left and right side portions of each shield member are holes having the same center of curvature, and are formed so as to have the same curvature as the curvature of the shield member. A first shield member is disposed on the back side of the slider and a second shield member is disposed on the front side of the slider with the slider of the slide locking member interposed therebetween. Therefore, even when each shield member is slid along this slide hole and both shield members are stacked one after another, or when the shield member is slid, there is no gap between the first shield member and the second shield member. Since the slider constituting the slide locking member is disposed, a uniform gap is generated between the shield members by the thickness of the slider, and the curved surfaces of the shield members do not contact and rub against each other. Hard to get scratched.

  In order to solve the above-mentioned problem, the invention according to claim 3 is the protective cap with a disaster prevention surface according to claim 1 or 2, wherein the first slide hole and the second slide hole are formed with the first shield member and the first shield member. 2 When the shield member is slid to the lowest position and the entire face is covered with the disaster prevention surface, the position where the lower part in the left-right direction of the first shield member and the upper part in the left-right direction of the second shield member overlap each other It is characterized by being formed.

  When the first shield member is slid to the lowest position along the first slide hole, the first shield member is disposed in a state of covering the eyes and nose of the operator, that is, in a state of covering the upper part of the face, and the second shield member Is disposed so as to cover the operator's mouth and throat, that is, to cover the lower part of the face when being slid to the lowest position along the second slide hole. Therefore, a slight overlap between the lower part of the first shield member and the upper part of the second shield member is disposed in the vicinity of the upper part of the mouth from the lower part of the operator's nose. The band-shaped portion does not enter the person's field of view, and workability is not reduced.

  In order to solve the above-mentioned problem, the invention according to claim 4 is the protective cap with a disaster prevention surface according to claim 3, wherein the second slide hole is formed by changing the position of the center of curvature at the upper part. When the second shield member is slid to the lowest position along the second slide hole, the second shield member is moved so as to approach the first shield member, and the two shields arranged in an overlapping manner The structure is such that there is no gap between the parts and the two members are in close contact with each other.

  The first slide hole of the first shield member and the second slide hole of the second shield member have the same curvature, but the second slide hole of the second shield member is a long hole with the same curvature. The formation positions are different between the lower portion and the upper portion of the shape and are provided with steps. In other words, the center position of the curvature is made different between the lower hole and the upper hole, and the position of the upper hole is slightly changed from the side end of the shield member (the thickness of the slider disposed between the shield members). ) Only inwardly shifted positions. In this way, by shifting only the locus of the slide hole of the second shield member, when the second shield member is slid downward, that is, the slide locking member is locked to the upper part of the slide hole of the second shield member. When this occurs, the second shield member approaches the first shield member by the amount of the slide hole transition, and both shield members are in contact with each other in the left and right belt-shaped overlapping portions, and the entire face is covered as a single disaster prevention surface without a gap. Is called.

  According to the protective cap with a disaster prevention surface of the present invention, the disaster prevention surface capable of shielding the entire face is composed of a plurality of divided shield members, and each shield member is slidably provided, and these are superposed on each other in the cap body. In addition, since the entire face can be shielded by extending each shield member, the entire face of the operator can be reliably protected while maintaining the size of the protective cap itself as usual.

As shown in FIG. 1, a protective cap 1 with a disaster prevention surface includes a cap body (shell) 2, a storage guide member (seal guide) 3, a first shield member (eye shield) 4, and a second shield member (face guard) 5. Although not shown, the liner 6 is composed of parts such as a hammock, a headband, and a chin strap that are worn on the cap body 2.

  The cap body 2 is a hemispherical member that covers the head, and is composed of a hard shell (for example, FRP resin, ABS resin, polycarbonate resin, or the like). The storage guide member 3 is a member for guiding and storing the first seal member 4 and the second seal member 5 into the cap body 2 or guiding them from the cap body 2 to the outside of the cap pair 2 (front face). The synthetic resin is obtained by injection molding or punching a synthetic resin plate. The storage guide member 3 is attached and fixed in the cap body 2. The 1st shield member 4 and the 2nd shield member 5 are members which comprise a disaster prevention surface, are provided so that a slide is possible, and can cover the upper part and the lower part of a face, respectively, when it slides and expands out of the cap body 2. FIG. Both shield members 4 and 5 are formed by molding synthetic resin by injection molding or plate bending, and are formed in a transparent or translucent (smoked, colored product) form. In this embodiment, the disaster prevention surface is composed of two shield members, the first shield member 4 and the second shield member 5, but is not limited to this form, and may be composed of a plurality of divided members. For example, it may be composed of three or more shield members.

  A hammock and a headband (not shown) normally used for a protective cap are members that hold the cap body on the head and reduce the impact on the head together with the cap body, and are also used in the present invention. The liner 6 is a member for absorbing an impact applied to the head, and is made of, for example, foamed polystyrene, and is disposed between the cap body 2 and the hammock. The jaw string is a member for preventing the cap body 2 from coming off the head.

  The storage guide member 3 is disposed on both sides from the front portion in the cap body 2, and mounting holes 11 and 12 are provided in the lower circumferential direction. Of the mounting holes, the mounting holes 11 on both sides are fixedly attached to the inner wall of the cap body 2, and the central mounting hole 12 is fixedly fixed to the hammock. Thereby, a space is formed between the inner wall of the cap body 2 and the outer surface of the storage guide member 3 at the front part in the cap body 2, and this space is a storage space for the first shield member 4 and the second shield member 5. It becomes.

  The storage guide member 3 has a storage guide hole 13 formed of a plurality of elongated holes along the vertical direction of the face of the worker wearing the protective cap 1, that is, from the opening edge of the cap body 2 ( (Cap body ceiling). The storage guide hole 13 guides the disaster prevention surface (the first shield member 4 and the second shield member 5) into the cap body 2 or guides the disaster prevention surface stored in the cap body 2 to the outside of the cap body. The first shield member 4 is engaged with the storage guide hole 13 via guide locking members 14a, 14b, and 14c. The first shield member 4 slides along the storage guide hole 13 and can move in the vertical direction of the face.

  The first shield member 4 has a substantially mask shape, and the width in the vertical direction near the center is slightly wider than the width in the vertical direction on both the left and right sides. It is composed of a cubic curved surface having a curvature corresponding to the curved surface. Long hole-shaped slide holes (first slide holes) 15 extending in the vertical direction of the face are formed on both sides of the first shield member 4. The slide hole 15 is formed to have the same curvature as that of the curved surface of the first shield member 4. As will be described in detail later, by forming the curvature of the slide hole 15 in the same manner as the curvature of the first shield member 4, the first shield member 4 and the second shield member 5 do not rub against each other during sliding, and scratches are generated. Can be prevented.

  Similar to the first shield member, the second shield member 5 has a substantially mask shape, and the width in the vertical direction near the center is slightly wider than the width in the vertical direction of the left and right sides. And it is comprised from the tertiary curved surface which has a curvature corresponding to the curved surface of the left-right direction of a face, and an up-down direction, and this curvature is formed in the same value as the curvature of the 1st shield member 4. FIG. Further, on both sides of the second shield member 5, long hole-shaped slide holes (second slide holes) 16 extending in the vertical direction of the face are formed. The slide hole 16 is formed to have the same curvature as that of the curved surface of the second shield member 5, but is formed so that the position of the center of curvature differs between the hole in the lower region and the hole in the upper region. . That is, the slide hole 16 is formed by changing the track of the hole from the middle. Details will be described later with reference to FIG.

  The first shield member 4 and the second shield member 5 are connected by a common slide locking member 17 (17a, 17b, 17c) that engages with the slide holes 15 and 16. A slider 17a is disposed between the first shield member 4 and the second shield member 5, and the inner holder 17b is engaged with the slider 17a from the inner side (back side) of the first shield member 4 through the first slide hole 15. The outer holder 17c is engaged with the slider 17a from the outer side (front side) of the second shield member 5 through the second slide hole 16. With this configuration, the first shield member 4 slides by the length of the hole 15 along the first slide hole 15 with respect to the slider 17a, and can move in the vertical direction of the face. Further, the second shield member 5 slides by the length of the hole 16 along the second slide hole 16 with respect to the slider 17a, and is movable in the vertical direction of the face. The slide locking member 17 will be further described later with reference to FIGS.

  FIG. 4B shows that the first shield member 4 is slid along the storage guide hole 13 of the storage guide member 3 to the lowest position of the hole 13 and the second shield member 5 is moved to the first position of the first shield member 4. The first and second slide members 15 are slid to the lowest position of the hole 15 together with the slide locking member 17, and the second shield member 5 is further slid downward relative to the slide locking member 17. The slide lock 17 is locked at the uppermost position of the second slide hole 16. At this time, the first shield member 4 and the second shield member 5 are disposed so as to overlap each other in the lateral band-like region 22 indicated by the oblique lines at the lower portion of the first shield member 4 and the upper portion of the second shield member 5. A shield surface that covers the entire face with a uniform curved surface is formed.

  As described above, the curvature of the curved surface in the left-right direction and the up-down direction of the first shield member 4 is formed to be the same as the curvature of the curved surface in the left-right direction and the up-down direction of the second shield member 5. A slider 17 a is disposed between the first shield member 4 and the second shield member 5. Further, the slide holes 15 and 16 are formed at the same center angle and have the same curvature as the curvature of the curved surfaces of the first shield member 4 and the second shield member 5. Therefore, even when each shield member 4, 5 is slid along the slide holes 15, 16 and both shield members 4, 5 are overlapped in the front-rear direction, or when the second shield member 5 is slid, the first Between the shield member 4 and the second shield member 5 (position indicated by the arrow 23 in FIG. 2A), a gap corresponding to the thickness of the slider 17a constituting the slide locking member is formed. The curved surfaces of 4 and 5 do not come into contact with each other and rub against each other and are hardly scratched.

  Further, as described above, the slide hole 16 of the second shield member 5 is formed such that the position of the center of curvature is different between the hole in the lower region and the hole in the upper region, and the trajectory of the hole 16 changes from the middle. (Refer to FIG. 1 and FIG. 2 (a)). In contrast to the slide hole 15 of the first shield member 4, the central angle of the lower region of the slide hole 16 is equal to the central angle of the slide hole 15, and the hole of the upper region of the slide hole 16 is formed. Is formed with a slightly smaller central angle than the central angle of the slide hole 15. With this configuration, when the second shield member 5 slides along the lower region of the slide hole 16, the thickness of the slider 17 a is between the first shield member 4 and the second shield member 5 as described above. A minute gap is formed, but when the upper region of the slide hole 16 is reached, the second shield member 5 approaches the first shield member 4 due to the change of the orbit of the hole 16. And when the 2nd shield member 5 is slid to the lowest position, in the strip | belt-shaped area | region 22 where both of FIG.2 (b) overlaps, the clearance gap between the 1st shield member 4 and the 2nd shield member 5 disappears, both Will be in close contact. As a result, the entire face can be covered with a uniform curved surface from the first shield member 4 to the second shield member 5.

  This protective cap with disaster prevention surface 1 can not only protect the eyes of the operator by sliding the disaster prevention surface open when using the disaster prevention surface, but also can cover and protect the entire face, and slide storage when the disaster prevention surface is not used And it is a protective cap which can store a disaster prevention side in a cap body.
