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 FIG. 4 for an anti-off device and a protective hat having the anti-off device in accordance with this disclosure, the protective hat comprises: a pair of protective goggles 500, a binding strap 600, a hat body 700 and an anti-off device 100.

In FIGS. 4 and 5, the hat body 700 has a slot 71 and a snap portion 701. In a preferred embodiment, the outer side of the hat body 700 (which is a lateral side 703 in this embodiment) has a protrusion 7, and the slot 71 is formed at the protrusion 7; and the snap portion 701 is any position or structure that can be engaged with the hat body 700, wherein the snap portion 701 is the hat's lower edge 7011 (which is also the lower edge of the hat body 700 as shown in FIG. 5) in this embodiment. In addition, the hat body 700 further has a hat brim 702 extending sideway (or in a horizontal direction) towards the outside (as shown in FIG. 5).

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 FIGS. 1 to 3, the anti-off device 100 comprises an anti-off body 1 and a snap arm 2 which will be described below.

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 FIGS. 1 and 2).

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 FIGS. 4 and 5) or moving the protective goggles 500 upward to the external periphery of the hat body 700 to where both of the protective goggles 500 and the binding strap 600 are bundled (as shown in FIGS. 7 and 8), the binding strap 600 is still limited by the passage 13, so that the binding strap 600 has an anti-off effect.

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 FIG. 5), so that when the protective goggles are moved upward or downward, the binding strap 600 is displaced within the height of the passage 13 correspondingly.

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.

In FIGS. 1, 3, 5 and 6, the snap arm 2 comprises a base plate 21 and a tongue 22 and preferably further comprises two support arms 23. The base plate 21 has an end elastically and bendably coupled to the carrier plate 11 of the anti-off body 1, and an end of the tongue 22 and the two support arms 23 are elastically and bendably coupled to the other end of the base plate 21, and the other end of the tongue 22 has the snap body 223 protruded therefrom. Wherein, the tongue 22 and the two support arms 23 are arranged side by side with each other (or with a space apart and side by side with each other) and coupled to the other end of the base plate 21. Therefore, when the snap arm 2 is passed and inserted into the slot 71, the snap body 223 of the tongue 22 is engaged with the hat's lower edge 7011, and the two support arms 23 are elastically supported by two opposite inner walls 72 of the slot 71 as shown in FIG. 6, so as to maintain a stable insertion of the snap arm 2 and a secured engagement with the hat's lower edge 7011.

The tongue 22 has an engaging side 221 and a moving side 222 opposite to each other. The snap body 223 is protruded from the engaging side 221, and an activity space S is defined between the adjacent walls of the moving side 222 and the slot 71 as shown in FIG. 5. Therefore, if it is necessary to toggle the tongue 22 for disengagement, the tongue 22 will be elastically skewed in the activity space S or elastically bent to the snap body 223 to separate the hat's lower edge 7011. It is noteworthy that the moving side 222 of the tongue 2 2 may be thinned to form the required activity space S, but this disclosure is not limited to such arrangement only.

In FIG. 6 together with FIG. 1, at least one remaining part 214 which has not been coupled may be formed at the other end of the base plate 21. In this embodiment, two symmetrical remaining parts 214 are formed. In a preferred embodiment, the tongue 22 and the two support arms 23 are disposed between the two remaining parts 214, and the two remaining parts 214 are also arranged side by side with the tongue 22 and the two support arms 23. Therefore, after the snap arm 2 is passed and inserted into the slot 71, the two remaining parts 214 abut against the protrusion 7 and the snap body 223 is engaged with the hat's lower edge 7011 appropriately.

In addition, the snap arm 2 further has a bent portion 211 disposed at an end thereof, and the snap arm 2 is coupled to the anti-off body 1 by the bent portion 211, so that the snap arm 2 can use the bent portion 211 as an axis to skew with respect to the anti-off body 1. In FIG. 3, an included angle A formed between the snap arm 2, the bent portion 211 and the anti-off body 1 may be increased or described by the skew. In FIG. 5, after the anti-off device 100 of this disclosure is inserted into the slot 71 by the snap arm 2, the included angle A will be increased by the elastic distraction of the outwardly extended hat brim 702 (sideway or in a horizontal direction, so that after the snap arm 2 is inserted, an elastic clamping force is produced between the anti-off body 1 and the snap arm 2 automatically.

Compared with the prior art, this disclosure has the following effects: 1. The anti-off device 100 of this disclosure is a one-piece device, and thus has an easy mold manufacturing effect without requiring the manufacture and assembling two or more pieces of components and saves the trouble of the manufacturing and assembling procedure. 2. The snap arm 2 is elastically and bendably coupled to the anti-off body 1, and the anti-off device and the protective hat has the elastic engagement and disengagement effect to provide an easy assembling and disassembling of the hat body 700 and a quick and easy assembling and disassembling effect. 3. The anti-off device can be installed/uninstalled easily and quickly to/from different hat bodies 700, so that the users can use the hat body 700 that fits the shape and size of their head without the need of using an unfitted hat body 700 for the reason of the difficult assembling procedure. 4. The anti-off device 100 of this disclosure may be sold alone, and it is not necessary to sell the anti-off device and the hat body 700 as a set, and thus this disclosure has the effect of not occupying too much space.

While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
