    Mounting Device of Shield for Helmet
    [12] The present invention relates to a shield coupling device for a helmet, and more particularly, a shield that is installed in a helmet worn to protect the head from an external impact, and prevents wind or foreign matter from directly contacting the wearer's face. It relates to a coupling device of the shield for the helmet to be coupled to the helmet to be manipulated.
    [13] When driving two-wheeled vehicles such as motorcycles, a helmet must be worn under traffic regulations for safety reasons to protect the head of the occupant.
    [14] In addition, such a helmet is generally provided with a structure in which a shield can be opened and closed to secure a passenger's vision by blocking wind and sunlight from the front when driving a motorcycle, and to allow normal breathing. to be.
    [15] Such a shield is typically coupled to both side portions of the helmet by a coupling device, and the technology related to such a coupling device has been developed at home and abroad.
    [16] In particular, the applicant of the present invention has applied for a coupling device that can improve the assemblability through the domestic patent application No. 10-2001-0009502 and reduce the noise when opening and closing the shield.
    [17] 1 is cited as an example of a drawing disclosed in the above application, an alternative configuration of which is provided on the support bracket 100 attached to the opening side of the helmet and the fixed shaft 110 of the support bracket 100. Rotatingly coupled is composed of a locker 200 for separating or coupling the support bracket 100 with respect to the helmet shield (300).
    [18] Furthermore, a stopper 120 is provided on a base surface of the support bracket 100, which stopper 120 has a rack shape provided in the shield 300 when lifting or lowering the shield 300. By selectively biting the concave-convex surface of the fixing piece 310 it is possible to adjust the up and down angle of the shield (300).
    [19] By the way, in this prior application technology, since the stopper 120 and the fixed piece 310 are both made of a hard material, the stopper 120 and the fixed piece as the up and down angle adjustment behavior of the shield 300 becomes more frequent. The wear between the 310 is severe, eventually causing a problem that the service life of the support bracket 100 or the shield 300 is shortened.
    [20] In addition, in the conventional shield coupling device, in the raised or lowered state by rotating the shield 300, a separate means for maintaining the raised or lowered state is not provided, but the stopper 120 and the fixing piece 310 are not provided. Since it is only supported by the bite of the liver, the shield 300 is unstable in a situation where the wind force applied to the shield 300 is strong, such as when driving at a high speed, such as a motorcycle, so that the opening angle of the shield 300 is different from the wearer's intention. There is a problem that changes regardless.
    [21] SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to reduce the friction between the elements of the shield and the coupling device even in the frequent up and down angle adjustment of the shield to further extend the service life of the shield and the coupling device itself. The present invention provides a shield coupling device for helmets.
    [22] Another object of the present invention is to provide a shield coupling device for a helmet that can stably support the shield so that the open state of the shield is rotated and the wearer can be maintained at a desired angle.

    [27] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, the detailed description of the same parts as the prior art will be omitted.
    [28] 2 is a view showing a support bracket of a shield coupling device according to the present invention, wherein a locker 20 is assembled to a support bracket 10 for coupling a shield (not shown) to a helmet (not shown). The locker 20 has a function to allow the shield to be coupled to or separated from the fixed shaft 11 of the support bracket 10 according to the rotation angle, which is omitted in the description because it is described in detail in the foregoing application. .
    [29] Meanwhile, as shown in FIGS. 3A and 3B, the support bracket 10 has a shield (when lifting or lowering the shield 30, that is, when the shield 30 is rotated to allow an upward and downward angle adjustment). A fixed piece 31 of a rack structure bent in an arc shape and a stopper 12 selectively biting are formed in the circular shape, and an arc-shaped continuous arrangement structure is formed above the fixed piece 31 in the drawing. Many uneven parts 31a are formed, and the stopper 12 is bitten by the uneven parts 31a.
    [30] Here, the main feature of the present invention, the incision hole 10a is formed in a circular arc shape parallel to the arc of the fixing piece 31 on the base surface of the support bracket 10, the incision between the two incision hole (10a) A notch surface 10b, which is parallel to the ball 10a and raised at a height equivalent to that of the fixing piece 31, is formed from the base surface of the support bracket 10, and the stopper 12 is rotated when the shield 30 rotates. The stopper 12 is formed in a shape projecting downward from the cutout surface 10b so as to be elastically swinged between the cutouts 10a and selectively snapped to the uneven portion 31a of the fixing piece 31. Is in.
    [31] In addition, the final downward angle of the shield 30, that is, the shortest uneven portion of the fixing piece 31 that the stopper 12 bites at the position when the shield 30 is completely lowered to the lower side of the helmet, that is, FIGS. 3A and 3B. The convex-concave portion located at the left end in FIG. 3B is formed in the groove shape in which the stopper 12 can be seated, thereby preventing the shield 30 from flowing.
    [32] In addition, the protruding end 31b is formed on the opposite side of the uneven portion 31a of the fixing piece 31, and the protruding end 31b is formed on the base surface of the support bracket 10 at the final downward angle of the shield 30. A seating groove 13 may be formed, which may be seated, which also contributes to preventing the flow of the shield 30.
    [33] In particular, the seating groove 13 is preferably formed on the incision surface (10c) to be able to elastically swing when the protruding end (31b) is seated.
    [34] Here, the structure of the cut surface 10c is made in accordance with the structure of the cut surface 10b in which the stopper 12 is formed.
    [35] Hereinafter, the operation of the present invention as described above with reference to Figures 3a and 3b.
    [36] First, Figure 3a shows a state in which the shield coupled to the coupling device according to the present invention is closed, the groove shape located on the leftmost in the figure among the uneven portion 31a formed on the fixing piece 31 of the shield 30 The stopper 12 of the support bracket 10 is seated on the concave-convex portion 31a, and the protruding end 31b provided on the lower side of the fixing piece 31 has a lower incision surface 10c of the support bracket 10. It is seated in the mounting groove 13 formed in the).
    [37] In this state, the shield 30 is shielding the front view of the helmet wearer, so that the shield 30 can be prevented from flowing when the wearer rides at a high speed on a motorcycle.
    [38] And, Figure 3b shows a state in which the shield coupled to the coupling device according to the present invention is opened, which is the case when the shield 30 is opened by rotating upward in the state of Figure 3a, as shown in Figure 3a When the shield 30 is rotated in the state of 3b, the stopper 12 held by the concave-convex portion 31a of the fixing piece 31 is elastically swinged between the cutouts 10a between the cutouts 10a. The shield 30 is opened without difficulty while minimizing friction between the stopper 12 and the fixing piece 31.
    [39] On the other hand, in the case where the shield 30 is rotated from the state of FIG. 3B to the state of FIG. 3A, even when the protruding end 31b of the fixing piece 31 is seated in the seating groove 13 of the incision surface 10c. Similarly, the cutting surface 10c is elastically oscillated to minimize the friction between the protruding end 31b and the seating groove 13.
    [40] As such, the cut surface 10b and the cut surface 10c are elastically swinged between the cut holes to minimize the friction between the stopper 12 and the fixing piece 31 and between the protruding end 31b and the seating groove 13. Therefore, wear of these parts due to frequent rotation of the shield 30 can be reduced to a minimum.
