Description

Connecting device for helmet shield

The present invention relates to a helmet, and more particularly to a transparent window (shield) assembly structure is attached to the front of the helmet to protect the eyes of the driver.

In general, when riding a motorcycle such as a motorcycle, a head protection helmet must be worn to protect the heads of riders, and a shield is installed at the front of the helmet to prevent wind, snow, and rain generated from the front when driving. The shield is attached to protect the eyes and secure the forward vision and to eliminate the breathing disorder.

Conventional seal fastening structures used for this purpose are disclosed in detail in patent application 99-16069.

However, in the case of the conventional seal attachment structure described above, a coupler installed inside both sides of the shield is inserted into the rotating hole attached to both sides of the helmet from the front to the rear, and then the locker is rotated so that the coupler is inserted. The inlet is blocked so that the coupler is not separated, but it is very inconvenient to apply a force so that the flange formed around the coupler is inserted into the groove of the pivot. In particular, since the seal is made of thin plastic with a plastic material, it is not easily broken by the force applied in the assembling process, and an arc-shaped guide rib formed around the coupling hole opens and closes the seal up and down. Breakage occurred due to contact with parts (guides) around the opening of the turning hole. This has an assembly tolerance for assembling the coupling sphere to the rotational sphere and is mainly caused by the play caused by the assembly tolerance.

In order to open and close the shield during opening and closing operation of the shield, rack-shaped arrangements are formed on both sides of the shield to form a control tool, and a first elastic piece of fixing means is formed on the helmet so that the control tool and the first elastic piece are in elastic contact. By opening and closing the shielding angle could be adjusted. However, when the actual shield is opened and closed, the first elastic piece passes against the rack-shaped irregularities, so that the first elastic piece elastically hits the rack-shaped irregularities, that is, a "trouble" severe noise occurs. In particular, the rotating part of the shield is located very close to the ear of the wearer of the helmet, so that the noise is very loud and the small sound is heard in a closed space of the helmet.

The present invention has been devised in view of the above conventional problems.

It is an object of the present invention to provide an inconvenience in assembling and improving noise in assembling a helmet.

Another object of the present invention is to provide another shield assembly structure.

This will be described below in detail with reference to the accompanying drawings.

First, the configuration according to the present invention will be described in detail.

Referring to Figure 2, Figure 2 is an enlarged view of the main portion of the support bracket for rotatably supporting the shield according to the present invention, the support bracket 20 is on both sides of the opening 11 of the helmet (10) It is fixed through the fastening holes 21, respectively, to fasten the screws to the fastening holes 21 to attach the support bracket 20 to the helmet.

The support bracket 20 has a fixing shaft 22 for rotatably supporting the seal 40 on the base 20a and a tension member 23 for fixing the locker 30 to be described below so as not to rotate. And it is formed to protrude with a stopper 24 for fixing so that the open and close state of the shield (40).

The fixed shaft 22 extends to a predetermined height on the base 20a of the support bracket 20 to form a fixed shaft 22 constituting an empty space portion 22a. The fixed shaft 22 has a first flange 22c extending radially inwardly on the inner surface of the space portion 22a. The first flange 22c is cut in a predetermined section on the inner surface of the fixed shaft 22 to form the first key groove 22d. The tension member 23 extends from the base 20a of the support bracket 20 to a predetermined height so that the center portion thereof has an uneven shape 23a. The unevenness 23a region of the tension member 23 is configured to float from the base 20a. This is to give more elastic tension in the uneven portion 23a. The stopper 24 is for imparting a function of holding the shield to be opened and closed to be described later. The stopper 24 protrudes from the support portion rack 20 to a predetermined height.

The locker 30 is a component assembled on the fixed shaft 22 as shown in FIGS. 3 to 3B, and the locker 30 is assembled according to the rotation angle when the seal 40 is assembled or detached from the fixed shaft 22. It imposes confinement so that it can be separated or not. The locker 30 has an inner diameter 31 for receiving the fixed shaft 22 and has a second flange 32 similar to the first flange 22c described above on the inner diameter 31. The second flange 32 cuts a predetermined section to form the key groove 33. In addition, it has a long hole 34 for receiving the projection 22b of the fixed shaft and includes a parking pin 35 on the circumferential surface. In addition, the locker 30 includes a handle 36 and a fastening piece 37 extending outwardly under the circumferential surface thereof. The handle 36 is used to rotate the locker after engaging the fixed shaft. The fastening piece 37 is provided with the slide groove 37a. The locker 30 is rotatably assembled to the fixed shaft of the support portion racket through the fixing means.

As an example of the fixing means, a protrusion 22b is further formed on the outer periphery of the fixing shaft 22 so that the inner diameter of the locker 30 corresponds to the rotation radius category when the inner diameter of the locker 30 is coupled to the fixing shaft 22. After forming the engaging ring 25 on the base 20a, the projection 22b is inserted into the long hole 34 and engaged to engage the outer circumference thereof, and the engaging projection 25 is formed in the slide groove 37a. ) Is slidably coupled. Even though the rocker is rotated about the fixed shaft, the protrusion 22b slides along the long hole 34 and the locking ring 25 moves to slide along the slide groove 37a, but the rocker is not separated.

The seal 40 is coupled to the fixed shaft 22 described above and opened and closed while rotating up and down about the fixed shaft. The rotating shaft 41 and the shield inserted into the fixed shaft 22 are not separated from the support bracket 20. It is provided with a separation prevention jaw (42). As shown in FIG. 4B, the separation prevention jaw 42 is bent so that its end is bent toward “??” so that the bent surface slidably contacts the inner surface of the slide rail 26 of FIG. 2. In addition, the control piece 44 is attached to the inner surface of the shield 40 in a position adjacent to the separation bump 42. The control piece 44 includes protrusions in the form of unevenness 44a at both ends thereof. In this unevenness, the stopper 24 of the support bracket 20 shown in FIG. 2 is engaged to function to fix the position during the opening and closing operation of the shield 40.

The assembly process and operation of the present invention configured as described above will be described.

In the installation to open and close the shield 40 in the front opening 11 of the helmet body 10 as in the above configuration, respectively supported on both sides of the opening 11 of the helmet body 1 After the bracket 20 is positioned, a screw is inserted into the fastening hole 21 to be fastened and fixed to the main body. In order to assemble the locker 30 to the fixed shaft 22 of the support bracket 20 fixed with screws, the slide groove 37a of the fastening piece 37 is inserted to be caught by the catching ring 25 and then the fixed shaft 22 ) To the inner diameter 31 of the locker. At this time, when the locker 30 is pressed so that the protrusion 22b placed on the circumferential surface of the fixed shaft is inserted into the long hole 34, the protrusion 22b enters the long hole 34 to the upper end of the long hole 34. Will be caught. Accordingly, the locker 30 is rotatably assembled to the fixed shaft 22 by being coupled to the long hole 34 and the fastening piece 37 of the locker by the protrusion 22b and the slide groove 37a.

Accordingly, the locker 30 is rotatably assembled to the outer diameter of the fixed shaft 22. When the second key groove 33 of the locker is rotated to coincide with the first key groove 22d of the fixed shaft, the locking hole of the shield is mounted. Since the key 41a is able to enter into the second key groove 33, the rotary shaft 41 is inserted into the fixed shaft 22. When the locker is rotated in the coupled state, the parking pin 35 is elastically fixed while being positioned on the unevenness 23a of the tension member 23 of the parking pin 35 of the rocker 30 so that the rocker 30 To hold it back. Therefore, while the second key groove 33 moves along the rotation radius, the second flange 32 covers the key 41a so that the rotation shaft 41 is fixed so as not to fall out of the fixed shaft 22. Of course, the rotating shaft 41 is free to rotate on the inner diameter of the fixed shaft (22).

In this way, when the shield 40 is assembled on the support brackets 20 on both sides, the shield 40 opens and closes the opening 11 of the helmet 10 while rotating up and down about the rotation shaft 22. You can. Figure 5 is a side view of the main part showing the process of assembling the shield, Figure 6 shows a state in which the shield is opened in a locked state so that the shield is not separated through the locker, Figure 7 is the shield is closed, that is, of the helmet It is a side view which shows the state which closed the opening part with the seal.

As can be seen in Figures 5 to 6 when assembling the shield is assembled in the same state as the shield is open so that the end of the separation bump 42 is in contact with each other to slide on the inner surface of the slide rail 26. Therefore, since the shield 40 is opened and closed while the two surfaces are in contact with each other, the seal is not separated from the support bracket 20.

In addition, when lifting up to open the shield, as shown in FIG. 6, the seal 40 is rotated about the fixed shaft 22, and the stopper 24 is attached to the unevenness 44a of the control piece 44. As you get caught, the shield will catch you so that it doesn't come down by its own weight. On the contrary, when the shield is lowered, the stopper 24 is caught by the unevenness 44a of the opposite fixing piece 44, thereby providing a constant resistance so that the shield 40 is not easily opened.

As described above, the shield assembly structure of the helmet according to the present invention, when assembling the shield to the helmet, when the rotation axis of the shield is positioned on the fixed shaft on both sides of the helmet, the second keyway is formed by the elasticity inherent in the shield itself. It will be appreciated that the key is easily inserted so that assembly is very easy and simple. Therefore, the shield is not assembled by applying the force from the front to the rear as in the prior art, so that the shield is not damaged in the assembling process and thus, the assembly is very convenient. In addition, the stopper against the uneven portion during the opening and closing operation of the shield simply slides while passing, so no noise is generated. In the end, it provides the effect that unnecessary noise is not generated.
