Anti-off device, and protective hat having the same

Abstract

Disclosed are an anti-off device and a protective hat having the anti-off device. The protective hat includes a hat body, protective goggles, a binding strap and an anti-off device. The hat body has a slot; the protective goggles and the binding strap are bundled altogether with the hat body; the anti-off device includes an anti-off body and snap arm. The anti-off body has a passage; a snap arm integrally coupled to the anti-off body, and the snap arm is inserted into the slot and the snap body is detachably engaged with the hat body, and the binding strap is disposed in the passage, such that when the protective goggles are moved upward or downward, the binding strap is still limited by passage to achieve the anti-off effect.

Description

BACKGROUND OF THE INVENTION1. Technical Field[0001]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.2. Description of Related Art[0002]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.[0003]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 t...

AI Technical Summary

Benefits of technology

The patent text describes an anti-off device for a protective hat and how it can be easily attached to the hat. The device includes an anti-off body with a passage and a snap arm that is elastically attached to the anti-off body. The snap arm has a snap body that engages with a snap portion on the hat. When the protective goggles are moved downward and worn on a user's face, a binding strap is still limited by the passage to provide an anti-off effect. The technical effect of this device is to prevent the binding strap from being accidentally untightened or becoming dislodged from its original position on the hat, which could cause the protective goggles to become unsecured and fall off the user's face.

Problems solved by technology

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.
