The technical field relates to the anti-off effect of a binding strap, and more particularly to an anti-off device and a protective hat having the anti-off device.
This disclosure is directed to a protective hat such as a safety helmet used for riding motorcycles and bicycles or a hard hat used in construction sites, and a pair of protective goggles are added by using a binding strap to further provide eye protection. In other words, the protective goggles together with the binding strap are bundled to the outside of the protective hat.
To prevent the binding strap from falling off from the protective hat, the conventional protective hat generally includes an anti-off device. However, the conventional anti-off device is of two or more pieces, so that two or more molds are required and the cost is increased. In addition, the assembling will be more troublesome since it is necessary to assemble two or more pieces. Obviously, the conventional protective hat has the drawbacks including the difficulty of assembling/disassembling the anti-off device with/from the protective hat, and it requires users to take off the protective hat for the assembling/disassembling.
In view of the aforementioned drawback of the prior art, the discloser of this disclosure based on years of experience in the related industry to conduct extensive research and experiment, and finally provided a feasible solution as disclosed in this disclosure to overcome the drawback of the prior art.
Therefore, it is a primary object of this disclosure to overcome the aforementioned drawback of the prior art by providing an anti-off device and a protective hat having the anti-off device which have a better binding strap anti-off effect, an easy mold manufacture that can reduce or skip the troublesome manufacture, and a quick and easy assembling/disassembling effect.
To achieve the aforementioned and other objectives, this disclosure discloses an anti-off device for a protective hat, and the protective hat comprising a hat body with a slot and a snap portion, and protective goggles and a binding strap being bundled with the outer side of the hat body, and the anti-off device comprising: an anti-off body, having a passage; and a snap arm, elastically and bendably coupled to the anti-off body and having a snap body, and the anti-off body of the snap arm being passed and inserted into the slot and the snap body being detachably engaged with the snap portion and fixed to the outer side of the hat body, and the binding strap being disposed in the passage; thereby, when the protective goggles are moved downward and worn on a user's face and then moved to the outer side of the hat body, the binding strap is still limited by the passage to provide an anti-off effect.
This disclosure also discloses a protective hat having an anti-off device and comprising: a hat body, having a slot and a snap portion; a pair of protective goggles and a binding strap, surroundingly coupled to and jointly bundled with the outer side of the hat body; and an anti-off device, comprising: an anti-off body, having a passage; and a snap arm, elastically and bendably coupled to the anti-off body and having a snap body, and the anti-off body of the snap arm being passed and inserted into the slot and the snap body being detachably engaged with the snap portion and fixed to the outer side of the hat body, and the binding strap being disposed in the passage; thereby, when the protective goggles are moved downward and worn on a user's face and then moved to the outer side of the hat body, the binding strap is still limited by the passage to provide an anti-off effect.
The technical contents of this disclosure will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
With reference to
In
The protective goggles 500 and the binding strap 600 are surroundingly coupled with each other, so that the protective goggles 500 and the binding strap 600 in this status can be jointly bundled to the outside of the hat body 700. In other words, the surrounding method is used to connect them to the external periphery of the hat body 700.
In
The anti-off body 1 has a passage 13 provided for limiting the binding strap 600. Specifically, the anti-off body 1 comprises a carrier plate 11 and a clamping plate 12 arranged with an interval apart from each other, and the passage 13 is formed at the interval between the carrier plate 11 and the clamping plate 12, and the passage 13 has two openings 131 configured to be corresponsive to the lengthwise direction of the binding strap 600 (as shown in
The snap arm 2 is elastically and bendably coupled (or integrally coupled) to the anti-off body 1 and can be passed and inserted into the slot 71. Specifically, an end of the snap arm 2 is elastically and bendably coupled to the carrier plate 11, so that the snap arm 2 can be skewed elastically with respect to the anti-off body 1; and a snap body 223 is protruded from the other end of the snap arm 2. Therefore, when the snap arm 2 is passed and inserted into the slot 71 and then the snap body 223 is detachably engaged with the hat's lower edge 7011, so as to fix the anti-off device 100 of this disclosure to a lateral side 703 of the hat body 700. It is noteworthy that after the snap arm 2 is engaged, the other end will be protruded from the hat's lower edge 7011 and provided for the user to toggle for disengagement. The binding strap 600 is disposed in the passage 13 and limited by the passage 13. In this embodiment, the binding strap 600 is passed through the two openings 131 and disposed in the passage 13.
Regardless of moving the protective goggles 500 downward or wearing the protective goggles 500 on a user's face (as shown in
It is noteworthy that the height of the passage 13 is not specified in this disclosure, and the passage 13 of this embodiment has a height greater than (for example, at least twice as large as) the width of the binding strap 600 (wherein the width of the binding strap 600 is shown in
In this disclosure, the way of setting the binding strap 600 in the passage 13 is not limited, so that the binding strap 600 may situated in the passage 13 first, and then the binding strap 600 and the protective goggles 500 are surroundingly coupled to each other, or the binding strap 600 may be surroundingly coupled with the protective goggles 500 first, and then bundled to the external periphery of the hat body 700, and finally moved into the passage 13. The latter is used as an example for illustrating this embodiment of the disclosure as follows. The clamping plate 12 comprises two clamping plate members 121, wherein the two ends of the two clamping plate members 121 which are far away from each other are coupled to two opposite ends of the carrier plate 11 respectively by a connecting portion 14, and a notch 122 is formed between the two ends of the two clamping plate members 121 which are close to each other, so that the binding strap 600 can be entered into the passage 13 from the notch 122.
