Definitions
- the present invention relates to a wake stabilizer for a helmet and a helmet.
- Patent Document 1 Utility Model Registration No. 3050720
- the present invention has been made in view of the above circumstances, and can be stabilized by avoiding the fluctuation of the helmet from side to side even in winds (airflow) where the relative speed is high, thereby facilitating operation.
- Another object of the present invention is to provide a helmet wake stabilizer capable of preventing fatigue to the neck and a helmet including such a wake stabilizer.
- the present invention has taken the following measures.
- the wake stabilizer for a helmet according to the present invention is provided in a symmetrical arrangement in the cap wake on both the left and right sides of the cap wake that forms a partial spherical shape from the side to the rear of the helmet. It has a left stabilizer and a right stabilizer. These left and right stabilizers extend in a vertical direction from the side position of the rear flow portion of the cap body to the rear surface, extending at an angle that fits behind the helmet in a flat state, and the rear edge of the side rectification surface. It has a wind strip that creates a longitudinal edge that extends.
- the wind (air flow) passing through the left and right sides of the helmet is guided to the rear position as far as possible from the helmet along the side rectifying surface.
- the wind separation provided as the trailing edge of the side rectifying surface is smoothly separated from the wind separation part.
- the wake stabilizer according to the present invention may be integrally connected to each other in such a manner that the left and right side rectifying surfaces and the wind separating part cross the rear part of the cap body wake part.
- the side rectifying surface is preferably formed in a thin plate shape by a resin material. In this way, light weight can be achieved, and the weight burden of the entire helmet can be suppressed. There is also an advantage that high cost can be prevented.
- the helmet according to the present invention is configured in such a manner that the wake stabilizer as described above is provided in the cap body posterior part as an integrated retrofit state or a separate retrofit state.
- integrated retrofit state means that the wake stabilizer formed as a separate part is attached, bonded with FRP, etc., attached by an appropriate fixing method such as caulking, screwing, etc. at the helmet manufacturing stage.
- the finished product of the helmet, including the attached state refers to the finished product, and the ⁇ separately attached state '' means that the wake stabilizer is attached to the helmet that is completed as a distribution product by an appropriate fixing method.
- the helmet according to the present invention is configured by attaching the wake stabilizer according to the present invention to a helmet having a basic configuration, regardless of whether it is in the manufacturing stage or the distribution stage. Is.
- an adhesive method using a double-sided tape can be employed in addition to the appropriate fixing method described above. It also includes making the helmet and wake stabilizer detachable by using hook-and-loop fasteners and button-type hooks.
- a wake stabilizer may be integrally provided from the beginning (that is, as the helmet itself). That is, in the helmet, the side rectifying surface extended at an angle that fits behind the helmette in a flat state from the side positions on both sides that are symmetrical on the left and right sides of the cap body, and the rear of the side rectifying surface A wake stabilizer having a wind-separating part that has a vertical edge extending in the vertical direction at the edge is provided.
- the wake stabilizer does not need to be completed before being attached to the helmet body, and it is only necessary to have a wake stabilizer as a part of the configuration as a completed helmet (for example, when the parts for forming the side rectifying surface and the parts for forming the wind separation part are separate members, This includes the case where the wake stabilizer itself is provided.
- the wind separating portion may be a pair of left and right in a state in which vertical edges are generated at the rear edges provided separately on the left and right side rectifying surfaces.
- a single trailing edge is provided so as to be shared between the left and right side rectifying surfaces (the trailing edges of the left and right side rectifying surfaces are matched), and this trailing edge is formed as a vertical edge. If this is the case, there will be only one wind detachment, and this is possible.
- the top straightening surface extended from the top of the cap body in the flat state toward the rear in an angle that fits behind the helmet, and the rear edge of the top straightening surface extends in the horizontal direction. It is possible to provide a rear boiler having a wind strip that creates a lateral edge. In this case, the weight stabilizer may be provided at a lower level with the horizontal edge of the rear boiler as a boundary.
- the entire cap body including the wake stabilizer and the rear boiler can be integrally formed.
- the helmet comprising the helmet wake stabilizer and the wake stabilizer according to the present invention
- fluctuations to the left and right of the helmet are avoided and stabilized even in wind (air flow) at a high relative speed. . Therefore, it is easy to drive a motorcycle or the like, and the wearer has the advantage that the neck is less tired.
