Description

Improvement of helmet strap buckle device (Part 1)

This work relates to the field of safety fastener technology, and in particular refers to a fastening device used on the chin strap of a safety helmet as its creator and application.

Note that fasteners are ubiquitous in daily life. Most fasteners use male and female fasteners to be threaded or fixedly connected to the movable ends of two straps, while the other end of the two straps is fixed to an object. This allows the male and female fasteners to be aligned and positioned, thus adjusting the tightness of the straps or tightening the two straps, such as the fasteners on safety helmets.

Early helmet buckle designs allowed for adjustment of length and tightness via straps, preventing them from easily coming undone in the event of an impact or tilting due to wind resistance at high speeds, thus achieving durability and safety. Industry standards include Notice No. M628696 "Buckles", Notice No. M628697 "Buckles", and Notice No. M445864 "Improved Buckle Structure". However, these buckles are generally snap-on buckles, requiring pressing a button to release them. But pressing the button down too tightly can make it difficult to operate, resulting in inconvenience.

Therefore, the creator actively researched and developed a previously approved patent, No. M633234, "Improvement of Helmet Strap Fastening Device," which includes a fastening base having a base plate and connecting plates on both sides of the base plate. A fastener is mounted between the two connecting plates, and a snap-fit can be inserted between the fastener and the base plate for interlocking. Its characteristic feature is that the end of the fastener has a raised portion, and there is a space between the raised portion and the base plate of the fastening base for inserting a finger to rotate the fastener. This structural technology improves upon the shortcomings of traditional structures on the market and makes them more practical.

However, besides the technology meticulously developed by the creator, there is another type of fastener in the industry, such as the magnetic fasteners in European Patent EP3192388 B1 "CLOSURE DEVICE" and Chinese Patent CN105228480 A "Closing Device," etc. These generally have a first and a second closing component, each with a magnetic component. When the second closing component is attached to the first closing component, they are magnetically attracted to each other to close the device. However, to ensure a good closing effect, this type of magnetic fastener mostly uses strong magnets, allowing them to be tightly connected and not fall off. Therefore, it is difficult to operate and detach them.

Therefore, based on years of experience in manufacturing such products and a spirit of continuous improvement, the creator has developed and provided an improved helmet strap buckle device (I) through continuous research and development, in order to achieve better practical value and benefit all consumers and the industry.

The main purpose of this invention is to provide an improvement to the helmet strap fastening device, especially a fastening device with magnetic function, which can achieve fastening quickly and securely.

The main purpose and function of this improved helmet strap buckle device are achieved through the following specific technical means:

It mainly includes a magnetic buckle base, which corresponds to a magnetic connector in a combination that can be relatively detached or magnetically attracted together. One end of the magnetic connector is provided with a raised part, and there is a gap between the raised part and the magnetic buckle base for manipulating the magnetic connector. In this way, the user can quickly and securely fasten the helmet strap through magnetic technology, and can use a single finger to insert into the gap space to manipulate the magnetic connector from the magnetic buckle base, achieving the effects and advantages of fast and convenient operation.

A preferred embodiment of the improved helmet strap fastening device of this invention includes a first magnetic element embedded in the end face of the magnetic buckle seat, and a second magnetic element that can attract each other at the location corresponding to the first magnetic element in the magnetic connector.

A preferred embodiment of the improved helmet strap fastening device of this invention includes a hook portion on one side of the first magnetic component of the magnetic buckle seat, and a first abutment flange that can be mutually locked and limited at the hook portion of the magnetic connector.

A preferred embodiment of the improved helmet strap fastening device of this invention includes a limiting portion provided on the other side of the first magnetic element of the magnetic buckle, and a second abutment provided on the magnetic coupling corresponding to the limiting portion, which can mutually restrict each other.

A preferred embodiment of the improved helmet strap fastening device of this invention, wherein the magnetic buckle forms an angle with respect to the upturned portion, the angle providing space for the fingers to insert.

A preferred embodiment of the improved helmet strap fastening device of this invention includes a slot on the raised portion, and a pull buckle is fitted into the slot to assist in pulling the raised portion.

To more fully and clearly reveal the technical content, creative purpose, and effects achieved in this work, a detailed explanation is provided below, along with the accompanying drawings and figure numbers:

First, please refer to Figures 1-3, which show the exploded view, assembled appearance, and sectional view of the improved helmet strap fastening device of this invention. It mainly includes:

A magnetic buckle (1) has its first end connected to the helmet strap (A) and a first magnetic element (11) embedded on its end face;

A magnetic connector (2) has a first end that is connected to the helmet strap (A). The magnetic connector (2) has a second magnetic element (21) that can be detached or magnetically positioned relative to the first magnetic element (11). The second end of the magnetic connector (2) has a raised part (22). There is a gap (23) between the raised part (22) and the magnetic buckle (1) for moving the magnetic connector (2).

A groove (20) is further provided on the magnetic connector (2), and the second magnetic component (21) is assembled and embedded in the groove (20).

Please refer to Figures 1-4. When in use, this helmet strap buckle device is used for vehicle helmets, engineering helmets, etc. The two sides of the helmet strap (A) are respectively attached to the first end of the magnetic buckle (1) and the first end of the magnetic connector (2). When the user wears the helmet, the second magnetic element (21) of the magnetic connector (2) is magnetically attached to the first magnetic element (11) of the magnetic buckle (1). In order to achieve a better magnetic effect, the first and second magnetic elements (11) and (21) are made of strong magnets. In this way, the magnetic connector (2) and the magnetic buckle (1) can be stably attached together [as shown in Figures 2-3].

Furthermore, a hook portion (12) is provided at the second end of the magnetic fastener (1), and a first abutment edge (24) is provided at the hook portion (12) corresponding to the magnetic fastener (2) for mutual locking and limiting; at the same time, a limiting portion (13) is provided between the first end of the magnetic fastener (1) and the first magnetic member (11), and a second abutment edge (25) is provided at the limiting portion (13) corresponding to the magnetic fastener (2) for mutual limiting. With the above structure, when the magnetic connector (2) and the magnetic buckle (1) are magnetically positioned, the design of the hook part (12) corresponding to the first abutment edge (24) and the limiting part (13) corresponding to the second abutment edge (25) allows the magnetic connector (2) and the magnetic buckle (1) to be accurately positioned so that the second magnetic element (21) and the first magnetic element (11) can be accurately magnetically positioned without deviation.

When disassembling the magnetic connector (2), please refer to Figures 1 to 4. The user inserts a single finger into the gap space (23) between the raised part (22) and the magnetic clasp (1). Within the gap space (23), the raised part (22) of the magnetic connector (2) forms an angle (X) with respect to the magnetic clasp (1), and the angle (X) provides space for the finger to be inserted [as shown in Figure 4]. When the user inserts their finger, they can lift the raised part (22) at the second end of the magnetic connector (2) upwards, causing the second abutment (25) to disengage from the limiting part (13). At the same time, the first end rotates downwards, causing the first abutment (24) to disengage from the hook part (12), so that the second magnetic element (21) and the first magnetic element (11) are in a disengaged state, allowing the magnetic connector (2) to be smoothly detached from the magnetic fastener (1).

In addition, a slot (221) is provided on the raised part (22), and a pull buckle (26) is sleeved on the slot (221). The pull buckle (26) has the function of assisting in pulling the raised part (22).

The foregoing embodiments or diagrams are not intended to limit the structural form of this work. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this work.
