Abstract

A headgear (10) with an adjustable headband comprises a band (12), wherein the band (12) is provided with a first locking end (14) and a second rack end (16), and the second rack end (16) is received in a sliding lapping way so as to encircle the head part of a wearer in an adjustable way. The rack end comprises rack surfaces (28 and 30) with outward opposite surfaces and a plurality of concave openings (28A and 30A). The locking end comprises latches (24 and 26) partitioned from each other, having pairwise inwards opposite surfaces and biased by a spring. The latches selectively move to be jointed with and separated from the concave openings (28A and 30A). A shifting switch (18) is received on the lapping ends (14 and 16), so that the shifting switch (18) can selectively move between a first unlocking position and a second locking position. When the shifting switch is at the first unlocking position, the latches (24 and 26) are separated from the concave openings (28A and 30A) and the rack end can freely move relative to the locking end; when the shifting switch is at the second locking position, the latches are jointed with the concave openings and the rack end and the locking end are locked mutually.

The specific embodiment

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

strip ends

14,16 optionally.

Referring to Fig. 1-12, example shown embodiment relates to the headwear 10 for safety cap (not shown).Although this exemplary embodiment is relevant to safety cap, is appreciated that and can expects that headwear 10 of the present invention 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.From the opposite end of described central body part 20, extend keyed end 14 and tooth bar end 16.

Referring to Fig. 2, the keyed end 14 of headband band 12 comprises the setting element that is subject to spring-biased (latches) 24,26 in paired the facing separating, and described setting element can optionally move inward.Owing to having 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 make this toggle switch 18 optionally between the first unlocked position (Figure 11) and the second latched position (Figure 12), to move (referring to arrow 32), 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 engages and described tooth bar end 16 locks together mutually with described keyed end 14.

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

Referring to Fig. 7 and Figure 10, toggle switch 18 further comprises the relative actuator inclined-plane 38 extending internally that is positioned at

cannelure

36,40, when described toggle switch 18 is with respect to described bond end 14, described in during 16 slip, actuator inclined-plane optionally engages the outer surface of keyed end 14

setting element

24,26 above.When toggle switch 18 is in the unlocked position (Figure 11), described actuator inclined-

plane

38,40 is disengaged with described

setting element

24,26; When toggle switch 18 is during in latched position (Figure 12), described actuator inclined-

plane

38,40 engages with described

setting element

24,26.

Referring to Fig. 2,6 and 9, in order optionally toggle switch 18 to be positioned to unlocked position and latched position, the keyed end 14 of headband band 12 and toggle switch 18 comprise mutual coupling configuration.In the illustrated embodiment, this mutually mates configuration and comprises paired relative recess 42A, the 42B and 44A, the 44B(Fig. 2 that separate above the peripheral side edge of the keyed end 14 that is positioned at described headband band 12) and paired the brake 46A, the 46B that extend internally that separate that are positioned at the described cannelure 36 of described toggle switch 18.In order to allow the peripheral side edge of the headband band 12 of

contiguous recess

42A, 42B and 44A, 44B to move inward along side direction, the keyed end 14 of described headband band 12 comprises contiguous paired relatively recessed stomatoplastic longitudinal release groove 48A, the 48B separating.

Figure 11 shows the assembly being 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, in paired

recess

42A, 42B

outside locking brake

46A, 46B are positioned in, (right side of this figure) and actuator inclined-

plane

38,40 are disengaged with setting element 24,26.Forward Figure 12 to, for assembly is locked together, toggle switch 18 is slided into the left side (referring to the arrow in 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 in

brake

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

Therefore, the object of the invention is to: a kind of headwear with improved governor motion is provided, provide a kind of and there is 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.

Based on above reason, headwear of the present invention is considered to embody in terms of existing technologies obvious progress and has significant commercial advantage.

Although show in this application and described the specific concrete structure that embodies described headwear; but those skilled in the art be to be appreciated that can be below not departing from theory and the condition of scope under part is improved and is rearranged and so long as fall in the protection domain of appended claim book, to the improvement of part with rearrange the particular form that is not limited in this application to describe and illustrate.
