This application claims priority to a Taiwan Patent Application No. 100111545 filed on Apr. 1, 2011.
1. Field of the Invention
The present invention relates to a snorkel and a mouthpiece assembly of the snorkel, and more particularly, to a snorkel comprising a whistle and a mouthpiece assembly of the snorkel.
2. Descriptions of the Related Art
When participating in aquatic, underwater or snorkeling sports, people need to wear a snorkel so that they can still breathe the air over the water surface even when their heads are under the water. However, during these water activities, there may be emergency situations in which the person may need to call for help. To this end, a snorkel with a whistle has been proposed, for example, in U.S. Pat. No. 7,191,779 and Taiwan Patent No. TW M272744. Thereby, when the user of the snorkel encounters a danger, he or she can whistle to make a large sound for the purpose of giving an alert.
However, this kind of snorkel still has some shortcomings. In detail, with reference to
Generally, the mouthpiece 911 of the mouthpiece assembly 91 faces toward the user's mouth and is adapted to be bitten by the user for air exchange. In reference to
Further, when the user swims, the exposed whistle 912 is subject to large water resistance, which may cause the mouthpiece assembly 91 to shake. To prevent the shaking of the mouthpiece assembly 91, the user needs to bite the mouthpiece 911 harder, which may cause user's jaw fatigue.
In view of this, an urgent need exists in the art to provide a snorkel and a mouthpiece assembly of the snorkel which can overcome at least one of the aforesaid shortcomings.
The primary objective of the present invention is to provide a snorkel and a mouthpiece assembly thereof which allow for using a whistle conveniently.
To achieve the aforesaid objective, the snorkel disclosed by the present invention comprises a mouthpiece assembly and a tube. The mouthpiece assembly comprises the following: a main body; a mouthpiece connected to the main body; and a whistle, having a pivoting portion and a blowing portion opposite to the pivoting portion. The pivoting portion pivotally connects to the main body. The whistle is rotatable against the main body from a first position to a second position by means of the pivoting portion; and the blowing portion is closer to the main body when the whistle is at the first position than when the whistle is at the second position. The tube connects to the main body, and communicates with the mouthpiece.
The detailed technology and preferred embodiments implemented for the subject invention are described in the following paragraphs accompanying the appended drawings for people skilled in this field to well appreciate the features of the claimed invention.
Referring to
The mouthpiece assembly 11 comprises a main body 111, a mouthpiece 112 and a whistle 113. The main body 111 is of a hollow structure, and may be made of a soft material or a hard material. The mouthpiece 112 connects to the main body 111, and communicates with the interior of the main body 111. The mouthpiece 112 and the main body 111 may be formed integrally, or may be manufactured separately and then assembled together.
The whistle 113 has a pivoting portion 1131 and a blowing portion 1132. The pivoting portion 1131 pivotally connects to the main body 111 so that the whole whistle 113 can rotate relative to the main body 111 and the mouthpiece 112. The connection that can be rotated may be achieved in various ways; and in this embodiment, it is achieved in the following way (the present invention is not limited thereto): the pivoting portion 1131 is formed with a circular hole, and the main body 111 is formed with a round shaft which is adapted to be inserted into the circular hole. Additionally, the pivoting portion 1131 and the main body 111 can be assembled with each other in the form of a clearance fit or transition fit so that they can easily rotate relative to each other.
The blowing portion 1132 of the whistle 113 is opposite to the pivoting portion 1131, and is adapted to be held by the user in his/her mouth for blowing to make a sound. The detailed construction of the blowing portion 1132 can be readily understood by those of ordinary skill in the art and is not a concern in this embodiment, so it will not be further described herein. In other words, this embodiment has no limitation on the detailed implementation of the blowing portion 1132 of the whistle 113.
When the user applies a torque to the whistle 113, the whistle 113 can rotate against the main body 111 (and the mouthpiece 112) from a first position to a second position by means of the pivoting portion 1131. When the whistle 113 is at the first position as shown in
When the whistle 113 is at the second position as shown in
The tube 12 is connected to the main body 111 of the mouthpiece assembly 11, and communicates with the mouthpiece 112. That is, air inhaled into the tube 12 can flow into the mouthpiece 112 via the main body 111, and air exhaled into the mouthpiece 112 can flow into the tube 12 via the main body 111.
With the components of the snorkel 1 having been described above, the method for using the snorkel 1 will be described next.
In normal conditions (i.e., conditions without danger), the user can bite the mouthpiece 112 for air exchange and, in this case, the whistle 113 is at the first position. When encountering danger, the user can rotate the whistle 113 to the second position to make the blowing portion 1132 face his mouth and then bite the blowing portion 1132 to make a sound without having to rotate the whole mouthpiece assembly 11 by about 180 degrees against the tube 12 as in the prior art.
Referring to
The snorkel 2 is similar to the snorkel 1 in other aspects; for example, when the whistle 113 is at the second position as shown in
Referring to
Furthermore, the user can apply a force to the whistle 113 so that the whistle 113 can slide against the main body 111 from the third position (as shown in
The aforesaid special connection between the pivoting portion 1131 and the main body 111 can be achieved in various ways and, in this embodiment, is achieved in the following way.
Referring to
The outer surface 111A of the main body 111 has a position limiting bump 1112 and a cylinder 1113 disposed thereon. The position limiting bump 1112 is slidably and detachably connected to the first sliding slot 1133, and the cylinder 1113 is rotatably and slidably connected to the second sliding slot 1134. That is, the position limiting bump 1112 can slide in the first sliding slot 1133, and can be detached from the first sliding slot 1133 when sliding to an end of the second portion 11332; and the cylinder 1113 can slide in the second sliding slot 1134, and can rotate in the second sliding slot 1134 when the position limiting bump 1112 is in the second portion 11332.
When the whistle 113 is at the third position as shown in
Additionally, to ensure that the whistle 113 will not slide against the main body 111 in normal conditions, the outer surface 113A of the whistle 113 may further be provided with a positioning groove 1135 and the outer surface 111A of the main body 111 may further be provided with a positioning bump 1114 which is detachably connected to the positioning groove 1135. The positioning groove 1135 may be a dome-shaped groove, while the positioning bump 1114 may be a dome-shaped bump.
When the whistle 113 is at the third position, the positioning bump 1114 is located in the positioning groove 1135. Because the positioning bump 1114 and the positioning groove 1135 interfere with each other, the whistle 113 cannot slide easily. If it is desired to slide the whistle 113, the user must firstly apply a great pushing force to detach the positioning bump 1114 from the positioning groove 1135. Then, when the whistle 113 is at the first position or the second position, the positioning bump 1114 is detached from the positioning groove 1135.
In reference to
Furthermore, the outer surface 111A of the main body 111 of the snorkel 3 may also be provided with an accommodating groove 1111. When the whistle 113 is at the first position or the third position, the blowing portion 1132 is accommodated in the accommodating groove 1111.
According to the above descriptions, the snorkel of the present invention has the following features:
1. a smaller force is required from the user to rotate the whistle relative to the main body than that required to rotate the mouthpiece assembly relative to the tube;
2. the whistle can be accommodated in the accommodating groove of the main body, so other articles will not be easily hooked by the whistle; and
3. by means of the position limiting bump and the first sliding slot, the whistle will not rotate against the main body arbitrarily and can rotate only when being operated by the user; and
4. the whistle accommodated in the accommodating groove is subject less water resistance than conventional exposed one, so that, when user swims, the mouthpiece assembly will shake slightly or even no shake, which may decrease the user's jaw fatigue or injury.
The above disclosure is related to the detailed technical contents and inventive features thereof. People skilled in this field may proceed with a variety of modifications and replacements based on the disclosures and suggestions of the invention as described without departing from the characteristics thereof. Nevertheless, although such modifications and replacements are not fully disclosed in the above descriptions, they have substantially been covered in the following claims as appended.
