The specific embodiment

Generally, as shown in FIG. and the improved headwear 10 for the head safety product described in the application comprise: headband band 12, thus described headband band has the first keyed end 14 and with the second tooth bar end 16 of the received adjustable ground of slip bonding relation around wearer's head; Be used for the optionally toggle switch 18 of the locking and unlocking

strip ends

14,16.

Referring to Fig. 1-12, example shown embodiment relates to the headwear 10 for the safety cap (not shown).Although this exemplary embodiment is relevant with safety cap, is appreciated that and expects that headwear 10 of the present utility model can be used in other head safety products such as including but not limited to the helmet and face shield.

Referring to Fig. 1, headband band 12 is preferably molded and shaped for having single of central body part 20 by flexiplast, and described central body partly goes up with tongue piece 22, in order to described central body part 20 is fastened on the complementary accessory that is positioned at helmet inner crest face.Extend keyed end 14 and tooth bar end 16 from the opposite end of described central body part 20.

Referring to Fig. 2, the keyed end 14 of headband band 12 comprises the setting element that is subjected to spring-biased (latches) 24,26 in paired the facing that separates, and described setting element can optionally move inward.Because have the flexiplast structure, therefore described setting

element

24,26 is subject to spring-biased naturally.

Referring to Fig. 3, the tooth bar end 16 of headband band 12 comprises the relative

outer rack surface

28,30 that faces, and described rack surface has a plurality of

recess

28A and 30A separately.

Referring to Fig. 4,11 and 12, toggle switch 18 is received in the bond end 14 of headband band 12, around 16, thereby so that this toggle switch 18 can optionally move (referring to arrow 32) between the first unlocked position (Figure 11) and the second latched position (Figure 12), in the first unlocked position, setting

element

24,26 and recess 28A, 30A is disengaged and tooth bar end 16 can move freely with respect to keyed end 14; At the second latched position place, setting

element

24,26 and recess 28A, 30A engage and described tooth bar end 16 locks together mutually with described keyed end 14.

Referring to Fig. 5-7, toggle switch 18 is preferred molded and shaped and comprise roughly rectangular body 34 and extend through the cannelure 36 of described body by plastic material.In use, received cannelure 36 and the described toggle switch 18 of passing of the described tooth bar end 16 of overlap joint and described keyed end 14 can be with respect to the described tooth bar end 16 of overlap joint and described keyed end 14 slide mobile (equally referring to Fig. 4 and Fig. 8).

contiguous recess

42A, 42B and 44A, 44B moves inward along side direction, the keyed end 14 of described headband band 12 comprises contiguous paired relatively recessed stomatoplastic vertical release groove 48A, the 48B that separates.

Figure 11 shows the assembly that is in the unlocked position, and in this unlocked position, tooth bar end 16 can move freely with respect to keyed end 14.In this position, (right side of this figure) and actuator inclined-

plane

38,40 are disengaged with setting

element

24,26 among paired recess 42A, the 42B

outside locking brake

46A, 46B are positioned in.Forward Figure 12 to, for assembly is locked together, toggle switch 18 is slided into the left side (referring to the arrow among Figure 11).In this position, actuator inclined-

plane

38,40 and setting

element

24,26 engage and promote terminal and the tooth bar recess 28A of setting

element

24,26, and 30A forms joint, and lock among

brake

46A, 46B zone paired recess 44A, the 44B inside being fixed on.

Therefore, the purpose of this utility model is: a kind of headwear with improved governor motion is provided, provide a kind of and have simple toggle switch in order to the improved governor motion of the movement of the locking and unlocking strip ends, and a kind of improved headwear is provided, described headwear comprises the regulatory function parts that can be manufactured into two parts that are easy to fit together.
