And the mainboard 21 and the subplate 22 of the 2nd plate 20 can open and close on the B direction.When the protuberance of mainboard 21 2121 inserts in the recess 223 of subplates 22, keep the closure state of mainboard 21 and subplate 22 with the mode that can remove.
Fig. 8 is the side view and the front elevation of appurtenances 30.Figure 10 illustrates the schematic sectional view that appurtenances 30 is worn on the 1st plate 10 of the situation on the maintaining part 12 of the 1st plate 10.
Only utilize above-mentioned maintaining part 12 just can operation be worn the a1 of edge portion that utensil 100 is installed in safety cap A1 with mask, still, maybe be because the difference of the kind of slotless safety cap etc. and can't be reliably fixedly the time, use appurtenances 30.
Under this situation, shown in figure 10, when the hole 124 of the maintaining part 12 of appurtenances 30 being inserted the 1st plate 10 from the top, the tooth 321 of wearable components 32 meshes with the tooth of the 1st plate 10 14 and engages.When taking off appurtenances 30, the inner surface of wearable components 32 slave plate main parts 11 is floated a little and extract.
The holding member 31 of appurtenances 30 becomes along the shape of the curved surface of the a1 of edge portion of safety cap A1, therefore, in conjunction with maintaining part 12 function originally, even the shape of slotless safety cap and size change a little, also can keep the a1 of edge portion of safety cap A1 reliably.
Fig. 9 is the side view and the front elevation of appurtenances 40.Figure 11 illustrates the schematic sectional view that appurtenances 40 is worn on the 1st plate 10 of the situation on the maintaining part 12 of the 1st plate 10.
Only utilize above-mentioned maintaining part 12 just can operation be worn the a2 of edge portion that utensil 100 is installed in safety cap A2 with mask, still, maybe since have the groove safety cap kind etc. and can't be reliably fixedly the time, use appurtenances 40.
Under this situation, shown in figure 11, when the hole 124 of the maintaining part 12 of appurtenances 40 being inserted the 1st plate 10 from the top, the tooth 421 of wearable components 42 meshes with the tooth of the 1st plate 10 14 and engages.When taking off appurtenances 40, the inner surface of wearable components 42 slave plate main parts 11 is floated a little and extract.
The holding member 41 of appurtenances 40 becomes the shape (with reference to Figure 11) of the a2 of edge portion that pushes safety cap A2 from the top; Therefore; In conjunction with maintaining part 12 function originally,, also can keep the a2 of edge portion of safety cap A2 reliably even have the shape of groove safety cap and size to change a little.
Wait the explanation method for using of the safety cap A1 of formation like this with reference to Fig. 1.At first, wear with mask in operation and connect the both ends of operation on the utensil 100,100 respectively with the telescopic band 201 of mask 200.At this moment, shown in dotted line among Fig. 7, make operation pass the slotting general hole 222 of operation wears utensil 100 with mask subplate 22 with the end of the telescopic band 201 of mask 200 after, pass the fixing of mainboard 21 successively with hole 2123b, 2123a.According to fixing hole shape, can't simply extract the telescopic band 201 of operation with mask 200 with hole 2123a and 2123b.
In addition, when needs use appurtenances 30, wear with mask on the utensil 100,100 in operation in advance and wear appurtenances 30 respectively.
Then, the operator A1 that puts on a safety helmet, make operation with mask wear utensil 100,100 under the open mode with the mode that tilts a little from below insert the a1 of edge portion of safety cap A1 and install respectively.Using under the situation of goggles 300 with mask 200 with operation, making the telescopic band 310 of goggles 300 pass the otch dog hole 113 of plate main part 11, thereby install goggles 300.Fig. 1 (B) illustrates this state.
Then, when carrying out operation, catch switching that operation wears utensil 100,100 with mask with pressing tablet 2122, make mainboard 21 swing to the 1st plate 10 respectively, the outer surface of mainboard 21 is overlapped with the outer surface of the 1st plate 10 with finger.After the claw 213 of the 2nd plate 20 gets into the circular hole 13 of the 1st plate 10,, keep the closure state of the 1st plate 10 and the 2nd plate 20 through the elastic force of claw 213.
Meanwhile, operation is pushed subplate 22 with the telescopic band 201 of mask 200, and thus, subplate 22 is swung to mainboard 21 respectively and become closure state.That is, the inner surface of subplate 22 overlaps with the inner surface of mainboard 21.After the protuberance of mainboard 21 2121 got into the recess 223 of subplates 22, the elastic force of the snap-latch piece 2125 through being formed at recess 223 was kept the closure state of subplate 22 and mainboard 21.
Like this, when the 1st plate 10 and the 2nd plate 20 of wearing utensil 100,100 with mask when operation became closure state, the operation that is in falling state owing to deadweight was drawn towards operator's mouth with mask 200, finally is worn on operator's mouth.At this moment, movable board 212 and subplate 22 by operation with telescopic band 201 tractions of mask 200 and tilt naturally towards the direction of operation with mask 200, the result, movably board 212 and subplate 22 and operation become the straight line shape with the telescopic band 201 of mask 200.Fig. 1 (A) illustrates this state.
Like this; Movable board 212 and subplate 22 and operation become operating personnel's the individual differences of situation and position, mouth of straight line shape with the telescopic band 201 of mask 200 irrelevant fully; Therefore; Different with existing situation, operation can be correctly worn with mask 200, and the inching of the setting angle of safety cap A1 need not be directed against.
Opposite with above-mentioned situation, when not using operation, catch switching that operation wears utensil 100,100 with mask with pressing tablet 2122 with finger with mask 300, the 2nd plate 20 is swung to respectively and above-mentioned direction in the opposite direction.So the claw 213 of the 2nd plate 20 breaks away from from the circular hole 13 of the 1st plate 10, owing to the deadweight of operation with mask 20, the 1st plate 10 and the 2nd plate 20 become open mode.Accompany therewith, the protuberance 2121 of mainboard 21 breaks away from from the recess 223 of subplate 22, and owing to the deadweight of operation with mask 20, subplate 22 becomes open mode with mainboard 21.
Like this, when the 1st plate 10 and the 2nd plate 20 of wearing utensil 100,100 with mask when operation becomes open mode, movable board 212 with subplate 22 since operation with the deadweight of mask 200 towards the below.Accompany therewith, operation is left from operator's mouth with mask 200 and is fallen.Fig. 1 (B) illustrates this state.Operation is positioned at the forward a little position of face of operator's forehead lower position with mask 200, therefore, can not become obstacle especially.
And; Under the state shown in (B) of Fig. 1; In the time will taking safety cap A1, near the forehead of operation with mask 200 contact operators, safety cap A1 wears utensil 100,100 from operation with mask and breaks away from; Accompany therewith, take off operation with operation with mask 200 and goggles 300 and wear utensil 100,100 with mask.
In addition, method for using and the said method of safety cap A2 are identical, therefore omit its explanation.
As stated, also different even there is bigger individual differences in operating personnel's position, mouth with in the past, operation can be correctly worn with mask 200, and the inching of the setting angle of safety cap A1 or A2 need not be directed against.The 1st plate 10 and the 2nd plate 20 float from operator's face, therefore, also can cause discomfort hardly even the operator in use perspires.Can not feel operator's whole head by operation with mask 200 and goggles 300 constraints, it is very good to wear sense.Especially, even the operator who wears glasses, the part that does not also contact with spectacle-frame can make hardly and wear the sense variation.
And, in operation, put on or when taking operation, do not need all to take safety cap A1 or A2 at every turn with mask 200.Also be same when putting on or take goggles 300.When under operation wears utensil 100,100 with mask state has been installed, taking safety cap A1 or A2, take off operation together and wear utensil 100, operation with mask 200 and goggles 300 with mask.
Therefore, different with the situation of existing example, ease of use is very good, in the reality, human body is had under the dysgenic environment, can significantly improve the wear rate of operation with mask 200.And, through separately using appurtenances 30,40, can the slotless safety cap with have in the groove safety cap sharedly, ease of use is good in this respect.Have following advantage from the position of manufacturer: if prepare various appurtenances, then the expanded range of the kind etc. of the safety cap that utensil 100 can be suitable for is worn in operation with mask, can realize cost degradation.
The variation of safety cap then, is described with reference to Figure 12.Figure 12 is the summary side elevation that the state that has on the slotless safety cap is shown that is used to explain the user mode of safety cap.
Among the safety cap A3 shown here, it is not the left and right sides ear position that is worn on the a3 of edge portion respectively that operation is worn utensil 10 ', 10 ' with mask, but becomes one with safety cap A3.Operation is worn utensil 10 ' with mask and is worn utensil 10 big different places with above-mentioned operation with mask and be there is not maintaining part 12, a distolateral left and right sides ear position that is fixed on the a3 of edge portion of safety cap A3 of plate main part 11.In addition, can certainly make safety cap A3 wear utensil 10 ' with operation with mask and separate, both become one through connections such as screws.
Like this, operation is worn utensil 10 ' with mask and is fixed on the safety cap A3, therefore, does not need appurtenances 30,40.In addition to wear utensil 10 with mask identical with above-mentioned operation, therefore, omits its detailed description.
In addition, operation of the present invention is worn utensil with mask and is not limited to above-mentioned embodiment, as long as not only under open mode, and under closure state, the part of the 2nd plate also can be rotated with respect to the 1st plate and got final product, and certainly carries out design alteration arbitrarily.
And, as long as the 1st plate edge portion that can keep safety cap, have nothing to do with the structure of maintaining part, whole shape and material etc., can suitably carry out design alteration according to the kind of safety cap etc.
The 2nd plate is as long as one distolaterally be connected with the 1st plate and in another distolateral end that can connect operation with mask with the mode that can fold; Irrelevant with the method for attachment that has or not subplate, plate, operation with the method for attachment of mask, whole shape and material etc., can suitably carry out design alteration according to the kind of safety cap etc.The integral body that also can design alteration becomes the 2nd plate is rotated freely with respect to the 1st plate.1st, the 2nd fixed cell needs only the closure state of keeping two plates with the mode that can remove, can adopt fixing means arbitrarily, for example can use magnet or spring etc.
Safety cap of the present invention is not limited to above-mentioned embodiment, wears utensil as long as be provided with operation in the edge portion of safety cap with mask, and design alteration can suitably be carried out according to the kind of safety cap in its fixing means and fixed position etc.Especially, can take following form: be not operation to be worn utensil with mask be completely fixed on the safety cap main body, be provided with but open and close freely, so that when not using operation to wear utensil, can not become obstacle with mask.And, with operation with the kind of mask with to have or not goggles irrelevant.
