Abstract

The structure comprises a pair of attachment mechanisms 20 securable to opposite sides of the helmet, an angle-adjustable wind visor 40 for mounting pivotally to the attachment mechanism, and a cover plate 50. The attachment mechanism comprises a friction piece 24 and a U-shaped bracket 25 having center and side portions (252, 254, Fig. 4) and a respective catch (256) formed on the side portions. The wind visor has a pair of visor rings 42 having friction tracks 44 engageable with friction pieces 24 and each ring is rotatable on the U-shaped bracket while being prevented disengagement with the same. The cover plate is fitted to the attachment mechanism via protuberances 52, 54 engaging in slots 26, 27 and is provided with an enclosure wall 56 substantially at a bottom and rear circumference thereof to stop the wind visor in a first angular orientation. The wind visor is mountable to or detachable from the U-shaped bracket in a second angular orientation where the wind visor is rotated further back than in the first orientation. <IMAGE>

Description

TITLE: MOTORCYCLE HELMEI ANGLE-ADJUSTABLE WIND VISOR MOUNTING STRUCTURE The present invention relates generally to motorcycle helmets having angle-adjustable wind visc@@.

More particularly, the present invention relates to a mounting structure for motorcycle helmet angle- adjustable wind visors.

It is realized that motorcycle helmets equipped with angle-adjustable wind visors are used so frequently that their components e.g., the wind visor.

cover plate. etc., are liable to have accelerated ear caused directly or indirectly b fastening and locsening bolts and screws or the @ike.

An improved type of a motorcycle helmet is disclosed in my U.S. Application Serial No. 07/399.245, filed on August 28, 1989 and by this reference incorporated herein as if the same were reproduced herein. Although the device disclosed in that reference overcomes the above drawback or limitation of the prior art, additional improvements have been made theret@, Accordingly. it is an object of this invention to provide a motorcycle helmet with angle-adjustable wind visor that provides a far more simpler and efficient structure.

A further object of this invention is to provide a a mounting structure for motocycle helmet angle adjustable wina visors in order to facilitate the adjustment, mount and replacement operation of the motorcycle wind visor.

These and additional objects, if not set forth specifically herein, will be readily apparent to those skilled in the art from the detailed -description provided hereinbelow, with appropriate reference to the accompanying drawings Fiat. 1 is a perspective exploded vie of a motorcycle helmet in accordance with the invention; Fig. 2 is a side view showing an orientation where the wind visor is mounted on the attacnment means, as well as showing the cover plate being connected to the attachment means by a linking strip; Fig. 3 is 2 perspectie vie of the motorcvcle helmet of Fig. 1 in assembled arranaement:: and Fig. 4 is a detailed section view showing the attachment piece fixedi@ attached to the helmet body with the wind visor interposed therebetween.

Referring to the drawings. and more particularly to Figs. i and 3, there is shown a motorcycle helmet, generally designated by reference number 10, constructed in accordance with the present invention, The motorcycle helmet 10 substantially comprises a helmet bod 12 a pair of attachment means 20, a wind visor 40, and a respective cover plate 50 for each attachment means 20. The helmet bods 12 has a known construction and at least comprises a hole 14 accommodating a locknut 15 and a hole 16 on each side thereof. It should be appreciated that the arrangement of the attachment means 20 and cover plates 50 is duplicated at each side of helmet body 12.For purposes of simplifying the description only one upright member and one pair of parallel members is shown, The attachment means 20 substantially comprises an attachment piece 22 from which extends an integral friction piece 4. a U -shaped bracket 25 to be received b a rectangular opening 23 proviieo on the attachment piece 22 a first receiving slot 26 and a second receiving slot 27 spaced and offset from the first receiving slot 26. The fist and second receiving slots 26, 27 each are formed by a box-like element having one open side ana one slotted side. as can be oleariy seen from Fig. 1.The U-shaped bracket 25 has a center portion 252 and te side portions 254. The center portion 252 is provided a center hole. The side portions 231 each have a respective catch 256 on an outer surface thereof (cf. Fig. 4). 4 positioning lea is also integrally formed on the attachment piece 22 to engage with the hole 16 on the helmet body 12.

The wind visor 40 has a pair of visor rings 42 on opposite sides of its main body. The visor ring 92 is provided with friction tracks 44 on part of its inner side so that the wind visor 40 is engageable with the friction piece 24 and bracket 25 to adjust its orientation relative to the motorcycle helmet bod 12.

The visor ring 42 of the wind visor 40 also comprises a mounting hole 43 which has inner walls 432 on an inner circumference thereof with two securement slots 434 spaced diametrically opposite each other therebetween, It is understood from this construction that the visor ring 42 can be mounted onto the U-shaped bracket 2 only bv positioning the visor rin 42 in an orientation as shown b phantom lines in wiz. 2. such that the two securement slots 434 of the mounting hole 43 align with the side portions 254 of the U-shaped bracket 25 and permit the same to pass. In tnis manner.

the visor ring 42 is rotatably supported on the side portions $254 of the U-shaped bracket 25 such that the wind visor 40 is angle-adjustable or pivotally mounted on the attachment means 20.

Fig. 4 shows a detail section view of the interconnection for the attachment means 0, the wind visor 40 and the helmet body 12. The visor ring 43 is rotatable about the U-shaped bracket 25 and is andle- adjustable with the engagement of the friction tracks 44 and the friction piece 21. From the above. it should also be clear that the attachment means 20 can be fixedly secured to the motorcycle helmet bod 12 b screw 1 passing through the center hole of the Ushaped bracket 25 and the hole 14 to engage with the locknut 1, with the wind visor 40 pivotally interposed therebetween.

The cover plate DO comprises respective protuberances 52 and 54 of substantially T-shaped cross-section and an enclosure wall 56 substantially at a bottom and rear circumference thereon. The protuberances DO and 54 are frictionally insertable into the first and second receiving slots 26 and 27 so that the cover plate 50 is engageable with each attachment means 20 for covering the visor ring 42 of the wind visor 40. The enclosure wall 56 stops a rearward pivotal movement of the wind visor 40 in an orientation shown by the phantom lines in rig. 3, where the wind visor 40 is in a lower and more forward position than what was described in Fig. 2 for mounting the wind visor 40 to the attachment means 20.

As can be seen from Figs. 1 and 2, there is a linking strip 60 having one end releasably fixed to an anchoring cii? 28 provide on the attachment means 20 and the other end releasably fixed to another anchoring clip 58 provided on the cover plate 50. The linking strip 60 connects the cover plate 50 to the attachment means 20 even when the cover plate 50 is detached from the attachment means 50. This secures the cover plate 50 from being inadvertently lost during operation.

While the present invention has been explained in relation to its preferred embodiment, it is to be understood that various modifications thereof will be apparent to those skilled in the art upon reading this specification. Therefore, it is to be understood that the invention disclosed herein is intended to cover all such modifications as shall fall within the scope of the appended claims.
