Description

Head band adjusting structure of head-wearing type protective device

Technical Field

The present invention relates to an adjusting structure, and more particularly, to a headband adjusting structure for a head-mounted protection device.

Background

A typical head-mounted protective device is worn by a worker or an associated person in a hazardous work environment to prevent the head from being struck by a falling object or hitting a lower obstacle. In order to ensure that the head-mounted protection device can exert the maximum protection effect, the most important thing is that the head-mounted protection device cannot be loosened or deviated when being worn, and in order to enable users with different head sizes and head types to wear the head-mounted protection device properly, the head-mounted protection device is generally provided with adjustment structures, although the users can find the tightness suitable for the heads of the users through the adjustment structures, the adjustment structures enable the users to hold the female buckle belt with one hand, pinch the tail end of the male buckle belt with the other hand, and penetrate the male buckle belt into the female buckle belt or pull the male buckle belt out of the female buckle belt. However, when the adjustment operation is performed, the user needs to operate the male buckle belt in a pinching manner, which not only is not easy to apply force, but also is easy to slide relative to the fingers due to the smooth surface of the male buckle belt, thereby causing a problem of poor operation hand feeling.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1, fig. 2, and fig. 3, an embodiment of the headband adjusting structure 2 of the head-worn protection device 1 according to the present invention is adapted to be detachably mounted on the head-worn protection device 1. The head mounted protective device 1 comprises a body 11 enclosing a head mounted space 111. The headband adjusting structure 2 comprises four engaging members 21 detachably disposed at the inner edge of the main body 11 and located in the head wearing space 111, a main ring piece 22 connected to the engaging members 21 and located in the head wearing space 111, a female buckle strip 23 connected to one end of the main ring piece 22, a male buckle strip 24 connected to the other end of the main ring piece 22 and passing through the female buckle strip 23, and an auxiliary force applying member 25 integrally protruded on the male buckle strip 24. The combining component 21 is detachably clamped in the insertion groove 112 formed at the inner edge of the main body 11 through a tenon structure, and the main body 11 can be formed with more than four insertion grooves 112, so that the combining component 21 can be inserted into the appropriate insertion groove 112 as required. The main ring pieces 22 form four slide grooves (not shown) for the coupling members 21 to be disposed, respectively. Each sliding groove extends along the surrounding direction of the main ring piece 22, so that the corresponding combining piece 21 can slide along the sliding groove to adjust the position of the combining piece 21 on the main ring piece 22.

Referring to fig. 2, 3, and 4, the female buckle strap 23 includes a first strap portion 231 connected to one end of the main loop 22, a seat portion 233 connected to the first strap portion 231 and defining a through slot 232, and an adjusting buckle portion 234 disposed on the seat portion 233 and allowing for pressing. The male buckle 24 includes a second band portion 241 connected to the other end of the main ring piece 22, and a plurality of positioning teeth 242 continuously protruding from the second band portion 241 along the extending direction of the second band portion 241. The male buckle strap 24, the female buckle strap 23, and the main loop piece 22 cooperate to form a head loop 26. The female buckle strap 23 can be pressed to switch between an adjustment state and a positioning state as shown in fig. 4, when the adjustment buckle portion 234 is not pressed, one end of the adjustment buckle portion 234 opposite to the pressed portion extends downward into the through groove 232 and is clamped between any two adjacent positioning tooth portions 242, so that the male buckle strap 24 is fixed and cannot extend through relative to the female buckle strap 23, and at this time, the female buckle strap 23 is in the positioning state, and the size (the circumference) of the head-covering loop 26 is fixed. When the adjustment buckle part 234 is pressed, the adjustment buckle part 234 is deflected or deformed, so that the end clamped between the positioning teeth 242 moves upward as described above, and the positioning teeth 242 are no longer clamped, so that the male buckle belt 24 can pass through the female buckle belt 23 to adjust the size of the head covering ring 26, and the female buckle belt 23 is in the adjustment state. The auxiliary force applying member 25 is protruded on the second band portion 241 and has two concave arc surfaces 251 opposite to each other and recessed inwards, wherein one concave arc surface 251 faces the extending direction of the male buckle 24, and the other concave arc surface 251 faces the main ring piece 22.

The user can be wearing behind wear-type protector 1, press on one hand adjustment knot portion 234 makes female detains area 23 convert to the adjustment status, and another hand push is supported supplementary application of force piece 25 orientation the concave arc face 251 of main ring piece 22 makes second area somatic part 241 passes through the part of wearing groove 232 increases and dwindles the head ring 26 is established to the cover, and then makes wear-fast that can laminate user's head and be firm in the wear-type protector 1. Conversely, if the head of the user is larger than the head-engaging ring 26, the user can push the other concave arc surface 251 of the auxiliary force-applying member 25, so that the second band portion 241 is pulled outward, and the head-engaging ring 26 is enlarged by reducing the portion of the through groove 232, so that the user can find the size suitable for his head. After the size of the loop is adjusted to a suitable size, the user can release the adjustment buckle portion 234, and the adjustment buckle portion 234 is engaged between the two corresponding adjacent positioning tooth portions 242, so that the female buckle belt 23 is switched to the positioning state to fix the size of the head covering ring 26. The shape of the concave arc 251 enables a user to comfortably place fingers on the concave arc 251 and apply force, and the shape of the arc with cladding enables the user to apply force easily and not to slip easily, thereby achieving the effect of improving the operation hand feeling.

Referring to fig. 5, the head-mounted protection device 1 applied in the present embodiment may also be a safety helmet, in which case, the headband adjusting structure 2 only includes two engaging members 21, and the engaging members 21 are directly and pivotally fixed at the inner edge of the main body 11. In this way, the auxiliary force applying member 25 can also achieve the effects of facilitating the operation of the user and preventing the fingers from slipping off, so that the embodiment can be applied to various head-mounted protection devices 1, thereby having higher versatility.

In summary, the present invention uses the concave arc surface 251 of the auxiliary force applying member 25 to make the user easily apply force and not easily slip off when operating the auxiliary force applying member 25, so as to achieve the objective of the present invention.
