Description

{Braket For Safety Helmet}

The present invention relates to a helmet bracket, and more particularly, to a helmet bracket which has a variable length of a coupling between a helmet and a face protection device, so that when the wearer wears the face protection device, the wearer is stably worn on the face, When the equipment is removed, the rotation radius is sufficiently secured regardless of the size of the front helmet, so that the operator can easily remove the equipment and mount it on the top of the safety helmet. And the face protection device is mounted on the top of the safety cap as well as when the operator wears the face protection device on the face and is formed so as to give the rotation elastic force to the backward and downward direction of the operator, A safety motor that is prevented from escaping by receiving force in the direction It relates to Phuket.

Welding is a metal process that joins two or more solid metals together. High energy sources such as high-pressure electricity, oxygen, acetylene, argon, etc. are used for welding. The hazards and hazards caused by welding are caused by welding fumes (metal components contained in fumes), harmful rays, noise, and high temperature environment that arise in welding work.

Especially, in case of arc welding in a narrow and closed workshop, welding workers suffer health damage due to welding fumes and nitrogen oxides generated in the welding process. In recent years, as well as pneumoconiosis caused by welding fumes (welding fumes) Manganese poisoning accidents have occurred due to the use of the welding electrodes. Therefore, measures against the health problems of the welding workers are required.

In addition, not only strong light is emitted during welding, but splashes are splashed, which can cause visual damage if the operator's eyes are exposed to light, and can cause injuries such as damage to the operator's eye by debris. In order to protect workers from the risk of burns due to splintering such as heat on the face and neck or heatwood caused by heat generated during welding, it is necessary to protect the eyes from harmful rays generated during welding and cutting Face shields such as automatic shading welding surfaces and automatic light shielding goggles are widely used.

In particular, in a dangerous work environment, since the operator wears a safety helmet for safety, the facial protective equipment is rotatably attached to the safety helmet through a fastening means such as a strap so as to shield the operator's face or eyeball It is often provided to open the operator's face at the completion of the work. If facial protective equipment is not connected to the helmet, the operator may feel uncomfortable and the risk of loss may increase.

The conventional facial protection device fastening means includes a supporting plate having a supporting bar formed on a front surface thereof and a finishing cap coupled to an end of the supporting bar. The facial protective equipment attached to the support bar of the conventional facial protective equipment fastening means is rotated between the shielding position for shielding the operator's face with the rotation axis and the open position for opening the operator's face.

At this time, since the facial protective equipment is rotated by the fixed supporting bar, the rotating radius for rotating between the shielded position and the open position is the same. As a result, facial protective equipment such as an automatic light shielding welding surface or an automatic light shielding goggle is frequently caught on the upper surface of the safety cap or on the front window of the safety cap when the upper portion of the safety cap is high.

Therefore, since the facial protective equipment should be manufactured considering the section passing through the section where the turning radius is the greatest in the turning section (the front window of the safety helmet), the facial protection equipment is spaced upward from the helmet up to the length of the helmet front window in the open position, As the combined length of the helmet and the face protection equipment increased by the distance upwards, the center of gravity moved from the lower side to the upper side.

As a result, the center of gravity of the safety helmet and face protection equipment changes to the left, right, and rear of the worker even when the worker moves in the slightest direction. When the worker is bowed or tilted during the welding operation, the safety helmet is removed from the worker's head, There is a serious problem of safety that poses another form of risk to exposed workers.

In addition, the load of the safety helmet and the face protection equipment which are shifted to the left, right, and rear sides is applied to the neck of the worker, which causes a problem that the fatigue of the worker is greatly increased during the work. In addition, when the front window is installed on a long safety helmet, the worker must wear the helmet with the front window facing the rear so that the safety helmet can not be properly worn and the wearing comfort is significantly reduced.

In the embodiment of the present invention, the fixing bar 11 is provided with two types of fixing bars. A first fixing bar 11a for applying a fixing force to the inside of the pocket groove in a lateral direction and a second fixing bar 11b formed to be inclined toward the inner center of the safety cap so as to press the inner wall surface of the pocket groove.

To this end, the first fixing bar 11a is formed on both sides of the supporting portion 10, and the first pressing protrusion 11aa is provided laterally so as to correspond to the different types of helmet pocket sizes. The second fixing bar 11b is formed so as to be inclined inward in the vertical direction of the support portion 10 as shown in FIG. 5 so as to be tightly coupled to the safety cap pocket groove when the second fixing bar 11b is inserted into the pocket, So that a frictional force is generated between the second fixing bar 11b and the inner wall surface of the pocket groove.

The inner side of the pocket groove is pressed through the first fixing bar 11a and the first pressing protrusion 11aa and the inner surface of the pocket groove is pressed through the second fixing bar 11b and the second pressing protrusion 11ba So that the support portions 10 are fitted to both sides of the helmet so as to be tightly coupled. A coupling protrusion 12 is formed at the center of the support portion 10 on the outer side based on a state of being bound to the safety cap.

For reference, when the helmet bracket 1 of the present invention is installed in a helmet having no pockets, it is possible to attach the helmet bracket 1 to the outside of the helmet by bolting or the like. A more suitable method at this time is a method in which a separate accessory for substituting for the role of the safety pouch is installed in the safety helmet and the helmet bracket 1 of the present invention is attached to the accessory.

The rotary arm 20 is rotatably attached to the coupling protrusion 12 of the supporting part 10 and has a coupling groove 22 at one end thereof as a body of the helical bracket 1 according to the present invention. . The coupling portion 12 of the support portion 10 is inserted and fixed to the coupling hole 21 of the rotary arm portion 20 and the support portion 10 is rotatable about the rotary shaft.

One end of the strap connection portion 30 is interposed between the coupling grooves 22 of the rotary arm portion 20 and the strap connection portion 30 is rotatable from the rotary arm portion 20 with the combined portion as a rotary shaft And a connection ring 31 is formed at one end of the other end so that the fastening part of the strap or face protection equipment connected from the face protection equipment can be directly hooked. At this time, the strap is mainly used as a band-like elastic material. Cloth, plastic, and the like.

The rotation means 40 is formed at a portion connecting the support portion 10 and the rotary arm portion 20 and the coupling projection portion 12 of the support portion 10 is inserted into the coupling hole 21 of the rotary arm portion 20 A rotating spring (not shown) or the like is provided along the rotating shaft to impart a rotating elastic force to the rotating arm 20. [ In addition, in the embodiment of the present invention, the pivoting means 40 imparts a rotational elastic force to the pivot arm 20 in a rearward and downward direction. A detailed description of the direction of the pivoting elastic force will be described with reference to FIG.

FIG. 6 is an operation diagram illustrating the rotation of the rotary arm 20 and the strap connection 30 in the helical bracket 1 according to an embodiment of the present invention.

Referring to FIG. 6, it can be seen that the helical bracket 1 according to the present invention has two large rotatable rotary shafts. 6A shows an operation in which one end of the strap connection portion 30 is interposed between the engaging grooves 22 of the rotary arm portion 20 and is rotated with the rotary shaft as the rotary shaft. In FIG. 6B, 21 shows the operation in which the rotary arm 20 rotates with the coupling protrusion 12 of the support 10 inserted and fixed with the rotary shaft.

The shape of the helmet bracket 1 shown in FIG. 6B is the most similar to the basic shape of the helmet bracket 1 when the operator wears both the helmet and the face protecting equipment.

7 is a perspective view showing the operation of moving the helmet bracket 1 according to the embodiment of the present invention to the safety helmet C and the face protection equipment M so that the face protection equipment M moves between the shielded position and the open position. FIG.

7, a worker wears both the actual helmet C and the face protective equipment M, and installs the helmet bracket 1 according to the embodiment of the present invention between the helmet C and the face protective equipment M, And the operation mode when the facial protective equipment M moves between the shielded position and the open position can be confirmed.

For reference, the face protection apparatus M shown in the drawing is an embodiment of the mask detachment type automatic light shielding goggle developed by the applicant of the present invention. The face shielding apparatus M can be formed in a goggle shape to protect the eyes of the operator, And a masking portion including a face protection cover for covering the face.

7A shows a state in which the strap S is connected to both sides of the face protection device M and the strap S is connected to the connection loop 31 formed in the strap connection portion 30 of the helmet bracket 1 according to the present invention, The support portion 10 of the helmet bracket 1 is fastened by inserting the fastening bar 11 into the pocket CP formed in both sides of the helmet C. [

At this time, as described above, the rotary arm 20 is rotated backward and downward because the rotary arm 20 is given a rotating elastic force backward and downward with respect to the support 10, The hard mask bracket 1 is naturally kept in the 'C' shape because the cover M is closely contacted to the operator's face.

7B, when the operator attempts to remove the top of the safety helmet C in order to move the face protection device M to the open position, the helmet bracket 1, which was in the form of a "B" shape, The radius of rotation is increased not only by the length of the rotary arm 20 but also by the combined length of the rotary arm 20 and the strap connection 30.

Therefore, regardless of the size of the front window of the helmet C, the turning radius is sufficiently secured, and the face protecting apparatus M can be easily moved to the upper end of the helmet C. In addition, The length of the helmet bracket 1 can be increased so that the turning radius can be further increased when the operator pulls the facial protective equipment M toward the front of the face.

7C, when the operator moves the facial protective equipment M to the open position and mounts the facial protective device M on the upper end of the safety cap C, the rotary arm 20 again rotates backward and downward about the support 10, So that a full 'b' shape in which the force is applied downward to the face protection device M and the contact is made on the safety cap C can be stably maintained.

The combined length of the helmet C and the face protective equipment M is variable so that when the operator wears the face protective equipment M, the wearer is stably worn on the face, When the equipment M is removed, the turning radius is sufficiently secured irrespective of the size of the front window of the safety helmet C, so that the operator can easily remove the equipment and mount it on the upper end of the safety helmet C.

In addition, since the turning means 40 is provided so as to impart the rotational elastic force to the backward and downward direction of the operator, as shown in Fig. 7, not only when the operator wears the face protecting apparatus M on the face, Even if the equipment (M) is mounted on the top of the safety helmet (C), the face protection equipment (M) receives a force from the central portion of the worker's head to prevent the escape of the worker's safety and convenience. .
