  The present application relates to a safety belt used when working at a high place, and to storage of a safety belt lanyard and a hook.

Workers who work at high places such as construction sites use safety belts to prevent crashes. This safety belt includes a trunk belt, a lanyard composed of a rope and the like, and a hook. The operator wraps the torso belt around his waist and hooks the lanyard hook to a sturdy spot on the work site. When the operator falls off the foot and falls, the operator is suspended through the trunk belt, the lanyard, and the hook. In this way, accidents due to operator crashes are prevented.
When working at heights, workers wearing safety belts have hooks in their hands, and the hooks at the tip of the lanyard are prevented from dropping at a position higher than the operator's waist to reduce the impact load when preventing the fall. Moving around the work site while hanging on a robust mounting member that will not be damaged by the impact load of the time. However, when working on the site where the safety belt is not required, for example, when working on the ground, the worker gets in the way of work, so it is necessary to store a lanyard that is not used. For this purpose, the operator responded by placing the hook and lanyard in a storage bag suspended at a predetermined position of the waist belt or hanging it on a hook hanger.

When the hook and lanyard are stored in the lanyard rope storage bag, the lanyard and the hook sometimes get entangled in the storage bag.
Also, when the lanyard hook is hung on the hook hanger, one end of the lanyard is attached to the safety belt attached to the waist, so half the length of the lanyard hangs from the waist, so the lanyard and the hook get tangled It ’s gone. However, there was a risk that the part hanging down during the work would contact the structure and fall.
In order to avoid this state, as in the invention of Japanese Patent Application Laid-Open No. 2009-72531, a lanyard hanging tool having a hanging piece that can hang an excess length portion of a hanging lanyard and hang a ring-shaped portion was invented. However, since the lanyard is hung on the hanging piece at a plurality of places, when using the lanyard, it is necessary to remove the lanyard from the hanging piece of the lanyard without turning the lanyard.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1A and 1B are drawings of a safety lanyard storage device of the present invention, in which FIG. 1A is a front view thereof and FIG. 1B is a right side view thereof. FIG. 2 is a three-dimensional view thereof.
As shown in FIG. 1, a lanyard take-up piece 14 is provided upright by being bent at a right angle to an upper side of a substrate 11 made of a rectangular steel plate, and is held continuously bent outward at the tip thereof. A piece 15 is provided to form the hanging tool 1. The holding piece 15 is made smaller than the hook width of the lanyard hook so that the hook can be hooked.

A lanyard take-up piece 24 is vertically installed by bending a lower side of a rectangular adhesive plate 21 hinged by a hinge 30 at a central portion of the substrate 11 and is provided at the tip of the outer side. The holding piece 25 bent continuously in the direction is provided to form the hanging tool 2.
The lanyard take-up piece 14 erected on the substrate 11 and the lanyard take-up piece 24 erected on the adhesive plate 21 are parallel to each other, and the holding piece 15 and the holding piece 25 are on the outer side in a direction opposite to each other. It is assumed that the center line is on a straight line.

The belt insertion holes for mounting on the body belt are parallel to the central axis connecting the holding piece 15 and the holding piece 25, and two on each side so as to be parallel to both sides of the substrate 11. A total of four belt insertion holes 17, 17, 17, 17 are formed. The belt insertion holes 17, 17, 17, 17 are sized to allow the safety belt trunk belt to be inserted, and the belt insertion holes 17, 17, 17, 17 are attached to the trunk belt by inserting the trunk belt into the belt insertion holes 17, 17, 17, 17. It becomes.
Although not shown, the belt insertion holes have a total of two, one along each side of the substrate 11 in the vertical direction, or a total of two along one side and one along the other side. Three may be sufficient.
A temporary fixing member is disposed between the back surface of the adhesive plate or the surface at the opposite position of the adhesive plate of the substrate, and is soft-bonded. The safety belt lanyard storage device is formed with the above configuration.

The necessary holding force of the temporary fixing member is that the safety band lanyard is wound between the lanyard winding piece 14 and the lanyard winding piece 24 and the lanyard hook is hooked on the holding piece 14, that is, the lanyard is secured to the safety band. This is a force that allows the substrate 11 and the adhesive plate 21 to adhere to each other and maintain the lanyard winding state in the state of being wound and stored in the lanyard storage tool.
The required separating force of the temporary fixing member is the rotational force applied to the holding piece 25 when the lanyard hook is detached from the holding piece 15 and pulled upward in order to attach it to the upper attachment member when working at a high place. F acts so that the substrate 11 and the adhesive plate 21 can be separated.

Example 1
Example 1 is a case where the temporary fixing member is a permanent magnet having a predetermined magnetic force.
In Example 1, as shown in FIG. 1, the permanent magnet 33 is attached to the back surface of the adhesive plate 21 and is fixed to the substrate 11 when the lanyard is wound up.
Although not shown, the same effect can be obtained by attaching the permanent magnet 33 to the opposite surface of the adhesive plate 21 of the substrate 11.
The predetermined magnetic force in the permanent magnet is the same as the holding force described above, the substrate 11 and the adhesive plate 21 are fixed, and when the winding lanyard is pulled, the substrate 11 and the adhesive plate 21 can be easily separated. Magnetic force.

(Example 2)
Example 2 is a case where the temporary fixing member is a hook-and-loop fastener.
In Example 2, as shown in FIG. 4, the hook surface 52 of the hook-and-loop fastener is attached to the back surface of the adhesive plate 21, and the loop surface 51 of the hook-and-loop fastener is attached to the surface of the substrate 11 facing the adhesive plate 21.
Although not shown, the same effect can be obtained by attaching the loop surface of the surface fastener to the back surface of the adhesive plate 21 and attaching the hook surface of the surface fastener to the surface opposite to the adhesive plate 21 of the substrate 11.
The holding force of the hook surface 51 and the loop surface 52 of the hook-and-loop fastener is such that the substrate 11 and the adhesive plate 21 are bonded in the lanyard winding state, and the substrate 11 and the adhesive plate 21 are easily separated when the winding lanyard is pulled. It is possible power.

(Example 3)
Example 3 is a case where the temporary fixing member is an uneven member formed by press molding.
In Example 3, as shown in FIG. 5, the convex part 62 is formed by press molding so that it may protrude from the surface of the adhesive plate 21 to the back surface.
A concave portion 61 having a shape into which the convex portion 62 is fitted is formed at a location facing the convex portion 62 of the adhesive plate 21 of the substrate 11.
The convex portion of the adhesive plate 21 and the concave portion of the substrate 11 have a shape having a holding force for fitting the substrate 11 and the adhesive plate 21 in the lanyard winding state. Further, when the wound lanyard is pulled, the substrate 11 and the adhesive plate 21 have a holding force that can be separated.
Although not shown in the drawing, the same effect can be obtained by providing a concave portion on the back surface of the adhesive plate 21 and forming a convex portion having a shape in which the concave portion is fitted at a location facing the concave portion of the adhesive plate 21 of the substrate 11.

The belt insertion hole 17 of the lanyard storage tool for safety belt is arranged so that the rotating hook 2 is positioned below the hook 1 when the safety belt lanyard storage tool is attached to the body belt of the safety belt for crash prevention. , 17, 17 and 17 are inserted through the body belt.
When the hanger 2 is attached to the torso belt so as to be positioned below the hanger 1, the lanyard hook is placed on the waist of the operator when the lanyard wound and stored in the safety lanyard hanger is used at work in high places. If it is moved so as to be hooked on the upper structure, an upward force acts on the holding piece 25 on which the lanyard is hooked in synchronization with the movement of the lanyard, and the hook 2 rotates around the hinge 30. try to. When the hanging tool 2 rotates, the distance between the tip of the holding piece 15 and the tip of the holding piece 25 becomes shorter than the ring-shaped diameter of the lanyard being taken up, so that the lanyard take-up piece 14 and the lanyard take-up piece 24 take up. The bundle of lanyards that had been untied will be unwound and the lanyard will be in use.

On the contrary, when the hook 1 is mounted on the waist belt of the safety belt so as to be positioned below the hook 2, an upward force acts on the holding piece 15 in order to hook the lanyard hook on the upper structure. However, the hanging tool 1 does not rotate because it is connected to the body belt. Accordingly, the bundle of lanyards wound in a ring shape by the lanyard take-up piece 14 and the lanyard take-up piece 24 cannot be unwound, so that the operator cannot use the lanyard unless the lanyard is unraveled.
For this reason, it is essential to attach the safety belt lanyard holder to the fall-preventing safety belt body belt so that the rotating hanging tool 2 is positioned below the hanging tool 1.

Example 4
In Embodiments 1 to 3 of the present invention, a safety lanyard storage device that winds a lanyard in a direction perpendicular to the length direction of a safety belt for preventing a fall that is worn by an operator, and can hook a hook. However, in Example 4, a lanyard storage device for a safety belt capable of winding a lanyard in the same direction as the length of the body belt and hooking the hook will be described.

Example 4 is shown in FIG. The structure of the board | substrate and hanging tool of Example 4 and the adhesive board and hanging tool hinged by the hinges by the hinge at the center part of the board | substrate are the same as Examples 1-3.
In other words, the lanyard take-up piece 74 is provided upright at right angles to the left side of the substrate 71 made of a rectangular steel plate, and the holding piece 75 continuously bent outward is provided at the tip thereof. The hook 7 is formed by providing holding pieces 76 and 76 on the upper and lower sides of the holding piece 75 so as to be orthogonal to the holding piece 75 near the center. The holding piece 75 is smaller than the hook portion of the lanyard hook, and has a width that allows the hook to be hooked.
A lanyard take-up piece 84 is provided upright by bending it at a right angle to a right side of a rectangular adhesive plate 81 hinged to a central portion of the substrate 71 by a hinge so as to be pivoted outwardly at the tip thereof. The holding piece 85 bent continuously is provided, and the holding piece 86 is provided on the upper and lower sides of the holding piece 85 in the vicinity of the center of the holding piece 85 so as to be orthogonal to the holding piece 85 to form the hanging tool 8.
The lanyard 74 erected on the substrate 71 and the lanyard take-up piece 84 erected on the adhesive plate 81 are parallel to each other, and the holding piece 75 and the holding piece 85 extend toward the outside, which is a direction opposite to each other. The center line is assumed to be on a straight line.

As shown in FIG. 6, the belt insertion hole for mounting on the body belt is perpendicular to the central axis connecting the holding piece 75 and the holding piece 85 and is parallel to both sides of the substrate 71. A total of four belt insertion holes 77, 77, 77, 77 are formed by two on one side. The belt insertion holes 77, 77, 77, 77 are sized to allow the safety belt body belt to be inserted.
Although not shown, the belt insertion holes may be a total of two, one along both sides of the substrate 71, or two along one side and one along the other side. Good.
A temporary fixing member is disposed between the back surface of the adhesive plate or the surface at the opposite position of the adhesive plate of the substrate. The safety belt lanyard storage device is formed with the above configuration.

The temporary fixing member is described as a permanent magnet having a predetermined magnetic force. As shown in FIG. 6, the permanent magnet 33 is attached to the back surface of the adhesive plate 81, and is fixed to the substrate 71 at the time of winding the lanyard. When the substrate 71 and the adhesive plate 81 are separated, the bundle of lanyards is unwound and becomes in use.
The same effect can be obtained by attaching the permanent magnet 33 to the opposing surface of the adhesive plate 81 of the substrate 71.
In Example 4, even if a surface fastener is used as a temporary fixing member or a concavo-convex member formed by press molding, the same effect as in the case of a permanent magnet is obtained by the holding force of the surface fastener and the concavo-convex member formed by press molding. Is obtained.

Similarly to the first to third embodiments, the safety belt lanyard storage device according to the fourth embodiment is attached to the body belt of the safety belt for preventing a fall by inserting the belt for the safety belt through the belt insertion hole 77.
When the safety band lanyard storage device is attached to the waist of the torso belt of the safety belt for crash prevention, the hanging device 7 is in the front side (abdominal surface) of the worker, and the rotating hanging device 8 is in the rear direction of the worker. Install it so that it is on the back.
When the lanyard is taken up horizontally between the take-up piece 74 and the take-up piece 84, the holding pieces 76, 76 and the holding pieces 86, 86 are arranged so that the wound lanyard is not unwound. Become a role.

When the lanyard wound up and stored in the safety belt lanyard storage device is to be hooked on the structure in front of the worker above the waist in this attached state, the holding piece 85 works in synchronization with the movement of the lanyard. A force in front of the person acts, and the hanging tool 8 tries to rotate around the hinge 30.
When the hook 8 rotates, the distance between the tip of the holding piece 75 and the tip of the holding piece 85 becomes shorter than the ring-shaped diameter of the lanyard being wound, so that the bundle of lanyards being wound is unwound and the lanyard is in use. become.

On the contrary, when the hanging tool 7 is attached to the waist belt so as to be positioned on the rear side (back surface) of the worker and the hanging tool 8 is positioned on the front side (abdominal surface) of the worker, the holding piece 75 is synchronized with the movement of the lanyard. However, since the force in front of the operator acts on the upper side, the holding piece 75 does not rotate because it is connected to the waist belt. Therefore, since the bundle of lanyards wound and stored in a ring shape by the lanyard take-up piece 74 and the lanyard take-up piece 84 cannot be unwound, the lanyard cannot be put into use unless the lanyard is unraveled by the operator himself.
For this reason, the safety belt lanyard holder is provided with a safety device for preventing the fall so that the rotating hanging tool 8 is positioned on the rear side (back surface) of the worker and the hanging tool 7 is positioned on the front side (abdominal surface) of the worker. It is essential to wear it on the belt belt.
