Description

  The present invention relates to a helmet to which an antitheft function is added.

  Traditionally, wearing a helmet has been compulsory when driving a motorcycle, and for safety purposes, such as riding a bicycle or working in a dangerous area such as a construction site. There are many opportunities for users to wear helmets. These helmets are usually stored safely in the house or in lockers to prevent theft, but especially in the case of motorcycle helmets, they must be worn and traveled to travel destinations and shopping destinations. Therefore, it is necessary to devise a method for safe storage of the helmet especially at the destination. For this reason, some of the bodies with sufficient capacity, such as a scooter, have a space for housing a helmet in the body. However, in a normal motorcycle, there is no room for such a body, so the user must engage the helmet's chin strap with the handle or frame of the motorcycle or other hook members formed on the surface of the body. Keep it in a safe place.

  However, in motorcycles, there are a plurality of locations that can be used as handles, frames, and other hook members, and although helmets can be engaged with these locations, in order to maintain the engaged state in such locations. Since there is no locking means for locking, theft cannot be prevented. In addition, a hook member with a locking means for theft prevention may be provided in a motorcycle, but there may be only one hook member with a locking means for theft prevention. In the case of two-seaters, it is difficult to store helmets for two people. Also, when leaving the motorcycle while carrying the helmet, for example, when the user brings the helmet into the store, when the user removes the helmet from the body, only the helmet should be stored safely. I can't.

  Therefore, the present invention has been proposed in order to solve the problems of the conventional techniques described above, and an object of the present invention is to provide a helmet to which an antitheft function is added.

A space closed by the helmet body, one lock member, and the other lock member is formed by engaging the joint portion and the other engagement portion with each other and holding the engagement state by the lock means. can do. By forming the closed space in this way, the helmet can be stored safely while preventing theft by putting another member in the closed space. That is, when a hook member formed on a motorcycle is used as a member placed in the closed space, the helmet is attached to the motorcycle and can be safely stored while preventing theft. it can. Furthermore, the member to be placed in the closed space is not limited to a hook member formed on a motorcycle. For example, a telegraph pole, a pillar constituting a bicycle parking lot / parking lot, or a house It may also be a column or member installed in the store, and the lock member and the other lock member and the other in the state where these members and columns are placed in the closed space. By holding the state in which the lock member is engaged, the helmet is prevented from being stolen and can be safely stored.

  In the helmet according to the second invention (the invention according to claim 2), as in the first invention, the user places the helmet in the vicinity of a place where the user wants to store the one lock member and the other. Are engaged with each other by the one engaging portion and the other engaging portion, and the state of this engagement is held by the locking means, whereby the helmet body, the one locking member, and the other engaging portion are held. A space closed by the lock member can be formed. By forming the closed space in this way, the helmet can be stored safely while preventing theft by putting another member in the closed space.

For this reason, the user does not wear the helmet according to the present invention, and also carries the helmet with the one lock member, the other lock member, and the insertion lock member to prevent theft and to store the helmet without storing it. Can be carried by inserting their hands and fingers into the closed space. That is, since the helmet body is generally curved (spherical) in shape, it is difficult to carry because it is slippery and difficult to carry. For this reason, the user often carries the helmet while holding the chin strap. However, since the chin strap is loose with respect to the helmet, when the chin strap is gripped and carried, the helmet often vibrates greatly and is unstable and difficult to carry. On the other hand, in the helmet according to the present invention, the one lock member, the other lock member, or the insertion lock member is attached to the helmet main body, and particularly with respect to the helmet compared to the chin strap. Since it is more firmly attached, the user can carry the helmet with less vibration and more stable state.

  Hereinafter, a helmet according to the best embodiment of the present invention will be described in detail with reference to the drawings.

  A helmet 1 according to this embodiment is a helmet to be worn when a motorcycle is driven as shown in FIGS. 1 and 2, and includes a helmet body 2 and one lock member 3 positioned on the right side surface of the helmet body 2. And the other lock member 4 located on the left side of the helmet body 2. The helmet body 2 has a configuration similar to that of a helmet worn during normal motorcycle operation having a visor 2a, a neck pad 2b, and the like. The one lock member 3 includes a metal wire 5 and one numeric lock 6. One end of the metal wire 5 is placed in an opening 7 formed on the right side of the helmet body 2 toward the front side of the helmet body 2, and the other end of the metal wire 5 is The one number lock 6 is firmly connected. In addition, the other lock member 4 includes a metal wire 8 and the other number lock 9 in the same manner as the one lock member 3. One end of the metal wire 8 is placed in an opening 10 formed on the left side surface of the helmet body 2 toward the front side of the helmet body 2, and the other end of the metal wire 8 is The other number lock 9 is firmly connected. The metal wires 5 and 8, one number lock 6 and the other number lock 9 are all the same as the number locks generally used for locking and fixing bicycles and the like. That is, the metal wires 5 and 8 are formed by bundling a large number of metal wires having a small diameter, and have a shape that can be freely bent and wound and a toughness that cannot be easily cut. I have. Also, the one number lock 6 has a cylinder opening 6a formed on the other end surface opposite to the one end surface on which the metal wire 5 is firmly fixed by welding or the like, and the side surface is written with numbers. The four toroids 6b (numbers are omitted in the figure) appear, and only when the numbers written on the torus 6b are in a predetermined combination, the inside of the cylinder opening 6a The cylinder 9a with which the other number lock 9 mentioned later is equipped can be attached or detached. Further, the other number lock 9 has a cylinder 9a in which a number of irregularities are attached to a circular bar on an end surface portion to which the metal wire 8 is firmly fixed by welding or the like. As described above, the cylinder 9a can be attached to and detached from the cylinder opening 6a of the one number lock 6 described above. In addition, by inserting the cylinder 9a of the other number lock 9 into the cylinder opening 6a of the one number lock 6, the one number lock 6 and the other number lock 9 are engaged with each other. By rotating the toric body 6b as appropriate so that the number of the toric body 6b is different from the predetermined combination, the state of engagement is maintained. In this case, a closed space is formed by the helmet body 2, the one lock member 3, and the other lock member 4.

  Further, the opening 7 is located at the tip of the bulging portion 7a formed in a substantially cylindrical shape on the right side surface of the helmet body 2 toward the front side of the helmet body 2, and as described above. One end of the metal wire 5 is inserted into the helmet body 2 through the opening 7. In addition, a pulley (not shown) is disposed in the vicinity of the opening 7 inside the helmet body 2 so as to be rotatable by a rotating shaft (not shown), and one end of the metal wire 5 is fixed to the pulley. The metal wire 5 is wound up by the rotation. The pulley (not shown) is provided with a biasing member (not shown) that biases the metal wire 5 to rotate in the winding direction. Furthermore, the pulley prevents rotation by the biasing member, but prevents rotation in only one direction so that rotation by the user pulling out the metal wire 5 from the helmet body 2 is not hindered. A non-returnable locking member is locked, and the locking member can be released from a locked state for preventing rotation in one direction by operating the winding button 11. In addition, since the diameter of the one number tablet 9 is larger than the diameter (inner diameter) of the opening 7, all the metal wires 5 are wound in the helmet body 2. However, the one number lock 9 does not enter the opening 7, and the one number lock 9 is positioned immediately before the opening 7 as shown in FIG. Therefore, the user can pull out the one numeric lock 9 together with the metal wire 5 while resisting the biasing force by the biasing member (not shown). When the locking member is locked, the wire 5 is kept pulled out from the opening 7, and the user operates the winding button 11 to release the locking state of the locking member. Then, the metal wire 5 drawn out in this way is wound around the pulley as the pulley (not shown) is rotated by the biasing force of the biasing member. In this way, the metal wire 5 can be pulled out from the inside of the helmet body 2 through the opening 7, and the metal wire 5 is wound up by the operation of the winding button 11, thereby the helmet. Although it is accommodated in the main body 2, this is the same for the opening 10, and the metal wire 8 can be pulled out from the helmet main body 2 through the opening 10. The metal wire 8 is taken up by the operation of the take-up button 12 and stored in the helmet body 2. In addition, the said metal wires 5 and 8 are the middle parts which comprise this invention, one number lock 6 is one engaging part which comprises this invention, and the other number lock 9 is this invention. And the one numeric lock 6 and the other numeric lock 9 are also locking means constituting the present invention.

  Next, a method for safely storing the helmet 1 having the above configuration while preventing theft will be described. First, the user places the helmet 1 in the vicinity of the storage location. Then, the user pulls out the one number lock 6 and the other number lock 9 from the helmet 1 against the biasing force of the biasing member (not shown), extends the metal wires 5 and 8, and Any one of the metal wires 5 and 8 is inserted into a hook member F formed at a place where the helmet 1 is stored. Then, the user rotates the four toroids 6b of the one number lock 6 to match the numbers to open the unlocked state, and the cylinder 9a of the other number lock 9 is opened to the cylinder opening of the one number lock 6. The one number lock 6 and the other number lock 9 are brought into a locked state by being inserted into and engaged with 6a and then rotating the torus 6b arbitrarily. By such means, the storage of the helmet 1 in a state where the theft is prevented at a necessary place is completed. In the case where the metal wires 5 and 8 are so long that the metal wires 5 and 8 are pulled out from the inside of the helmet body 2 and extended. By operating the winding buttons 11 and 12, the metal wires 5 and 8 can be wound up and the lengths of the metal wires 5 and 8 may be adjusted. Moreover, as the hook member F used for storage of the helmet 1, the rod-shaped body bent in the U shape is shown in FIG. 2, but the hook member F is not limited to such a thing. It may be a motorcycle frame, a pillar or a telegraph pole that constitutes a building of a house, a store or a bicycle parking lot, and can pass or wind the metal wires 5, 8 as described above, and can be wound on the ground or a building. Any material that is firmly fixed may be handled in the same manner as the hook member F described above. Further, when finishing the storage of the helmet 1 stored by such a method, the user rotates the four toroids 6b of the one number lock 6 to the unlocked state according to a predetermined number, The cylinder 9 a of the other number lock 9 is taken out from the cylinder opening 6 a of the one number lock 6. Thereby, the helmet 1 complete | finishes the storage to the said hook member F, and a user operates the said winding buttons 11 and 12 and winds up the metal wires 5 and 8. FIG. In addition to the case of storage, the metal wires 5 and 8 are appropriately pulled out as described above, and the metal wires 5 and 8 are inserted into the hook member F and engaged with each other. By putting the lock 6 and the other number lock 9 into the mutually inserted state, the user puts his / her fingers into the closed space formed by the metal wires 5, 8, one number lock 6 or the other number lock 9. The helmet 1 can be easily carried around.

  Next, the helmet 21 which concerns on embodiment different from said helmet 1 is demonstrated. This helmet 21 is also a helmet worn when a motorcycle is driven as shown in FIG. 3 or FIG. 4, and includes a helmet body 22, a lock member 23 located on the back of the helmet body 22, and the lock member 23. And a support portion 24 that supports the main body 22 so as to be rotatable in the back direction.

It should be noted that an operation for inserting and rotating a not-shown key into the key hole 36 is required for both the operation of inserting the lock means 33 of the helmet 31 into the opening 35 and the operation of taking it out. However, when inserting, the above-described operation of inserting and rotating the key may be unnecessary, and the locking means 33 and the locking means (not shown) are also locked. Instead of forming the opening 33r in the means 33, the recess formed in the long prism 33d of the locking means 33 and the locking member (not shown) may be engaged to engage with each other.

  Thus, the helmet 21 or the helmet 31 is a member that is completely different from the helmet body 22 or the helmet body 32 on the surface of the helmet body 22 of the helmet 21 or the helmet body 32 of the helmet 31, Unlike the helmet body 22 or the helmet body 32, the lock members 23 and 33 are separately provided as members that function when the helmet body 32 is stored, but unlike this, a part of the shape of the helmet body itself constituting the helmet It is also possible to use a part of this helmet body as a lock member. That is, the helmet 41 is a helmet worn when a motorcycle is operated as shown in FIG. 7 or 8, and includes a helmet body 42 and a lock member 43 positioned in front of the helmet body 42. The helmet body 42 is similar to the helmet bodies 2, 22, and 32 of the helmets 1, 21, and 31. In particular, there is a difference in the configuration of the helmet bodies 2, 22, and 32 at the front. That is, the helmet bodies 2, 22, and 32 are so-called full-face helmets that cover the entire user's head, whereas the helmet body 42 is the front of the user's head (particularly, The nose and mouth) is a so-called jet-type helmet that is open to the outside. The helmet includes a visor 42a and a neck pad 42b, and a lock member 43 is used via a hinge member 44. By rotating to the front of the person's face, the appearance is a full-face helmet. That is, the lock member 43 is pivotally attached to the helmet body 42 via a hinge member 44, and is positioned in front of the helmet body 42 as described above, or rotates. Thus, it is positioned in the right side surface direction of the helmet body 42, and has a shape like the front end portion of a general full-face helmet. Therefore, as described above, by positioning the lock member 43 in front of the helmet body 42, the helmet 41 as a whole becomes a so-called full-face helmet as shown in FIGS. 7 and 8A. At the same time, the lock member 43 is rotated with respect to the helmet body 42 via the lock member 43, whereby the state shown in FIG. An opening 43a into which a locking member 46a described later is inserted is formed at the right end of the lock member 43. A keyhole 46 is formed near the front end of the right side surface of the helmet body 42. The user can operate a locking means (not shown) built in the helmet body 42 in a locked state or an unlocked state by inserting a joint key (not shown) into the keyhole 46 and rotating it. When the means is in the locked state, the locking member 46a protrudes from the front end of the right side surface in the vicinity of the key hole 46, and when in the unlocked state, the locking member 46a is within the helmet body 42. Stored. The locking member 46a that protrudes when the locking means (not shown) is locked is inserted into the opening 43a of the lock member 43, so that the lock member 43 is fixed to the helmet body 42. Since the locking member 46a is housed in the helmet body 42 by bringing the locking means into the unlocked state, the lock member 43 is rotatable with respect to the helmet body 42. Is done. In addition, in the state which rotated the lock member 43 as shown in FIG.8 (b), since the said locking member 46a does not protrude from the said helmet main body 42, in FIG.8 (b), the locking member 46a is shown with a dotted line. To express. Further, the opening 43a and the locking member 46a are engaged and held on the front surface of the helmet body 42, whereby the helmet body 42 and the lock member 43 allow the opening 42c (the helmet) in the visor 42a. When the wearer 41 is worn, a closed space is formed in an opening formed in front of the eye to obtain the user's field of view, and the space is held by the locking member 46a and locking means (not shown). The opening 43c is one engaging portion constituting the present invention, the locking member 43 is one locking member constituting the present invention, and the locking member 46a is the other constituting the present invention. The locking means (not shown) is a locking means constituting the present invention.

  Next, a method for preventing the theft helmet 41 having the above configuration from being stolen and storing it safely will be described. First, the user places the helmet 41 in the vicinity of the storage location. Then, the user inserts a key (not shown) into the keyhole 46 and rotates it to operate the locking means (not shown) to house the locking member 46a inside the helmet body 42 and unlock it. Then, the user rotates the locking means 33 with respect to the helmet main body 42 so that the column B is located between the helmet main body 42 and the lock member 43 as shown in FIG. The helmet 41 is moved. In this case, the positional relationship between the helmet 41 and the column B is such that the visor 42a is moved in the direction of the top of the helmet 41 and the column B passes through the opening 42c. Then, the user turns the lock member 43, positions the lock member 43 again in front of the helmet body 42, inserts a key (not shown) into the key hole 46, and turns to lock the locking means (not shown). , The locking member 46a protrudes from the helmet body 42 and is inserted into the opening 43a to obtain a locked state. By such means, the storage of the helmet 41 in a state where the theft is prevented at a necessary place is completed. The column B used for storage of the helmet 41 here is that the lock member 43 is larger than the lock members 3, 4, 23, 33 of the helmets 1, 21, 31, so the helmet B The thing larger than the hook member F used for storage of 1,21,31 is used, and the columnar body B like the cylinder which comprises a road sign is shown in FIG. However, the pillar body B is not limited to this, and may be a motorcycle frame, a pillar body or a telegraph pole constituting a building of a house, a store, or a bicycle parking lot, and it passes through the opening 42c as described above. Any material that can be fixed and firmly fixed to the ground or a building may be handled in the same manner as the column B described above. Further, when the storage of the helmet 41 stored by such a method is finished, the user inserts the above-mentioned unillustrated key into the key hole 36 and rotates it to bring the above-mentioned locking means (not shown) into an unlocked state. The locking member 46a is housed in the helmet body 42, and the lock member 43 is rotated. As a result, the helmet 41 finishes storage in the column B, and the user rotates the lock member 43 again and inserts the locking member 46a into the opening 43a, as shown in FIG. 8A. The lock member 33 is fixed. In addition to the case of storage, the user puts his / her fingers into an opening 42c, which is a closed space formed between the helmet body 42 and the lock means 43, and easily carries the helmet 41. be able to.

As shown in FIG. 10, the lower end of the lock member holder 64 is fixed on the surface of the helmet body 62 with hooks 64b and 65b so as to overlap the middle part 63c of the lock member 63. Thus, the middle part of the lock member 63 is locked to the helmet body 62. The lock member 63 is an insertion lock member constituting the present invention, and one engaging portion 63a and the other engaging portion 63b are formed at both ends of the lock member 63, respectively. These one engaging portion 63a and the other engaging portion 63b have a lock function for maintaining the engaged state, and are also the locking means of the present invention.

  Next, a method for securely storing the helmet 61 having the above configuration while preventing theft will be described. First, the user places the helmet 61 in the vicinity of the storage location. Then, the user operates the annular body of the one engaging portion 63a to the unlocked state with respect to the one engaging portion 63a and the other engaging portion 63b that are kept engaged. To release the engagement. The user is not shown in FIG. 10, but the one engaging portion 63a or the other engaging portion 63b is included in a member such as the hook member F shown in FIG. 2, FIG. 4, or FIG. Either of these is inserted. Then, the user rotates the four toroids of the one engaging portion 63a to adjust the numbers to the unlocked state, and the cylinder of the other engaging portion 63b is set to the cylinder of the one engaging portion 63a. The one engaging portion 63a and the other engaging portion 63b are brought into a locked state by being inserted into the opening and engaged, and then the torus is arbitrarily rotated. By such means, the storage of the helmet 61 in a state where the theft is prevented at a necessary place is completed. In addition, when the distance between the helmet 61 and the hook member at the time of such storage is long, the helmet body 62 and the lock can be locked by removing the hook 64b of the lock member holder 64 as necessary. The space closed by the member 63 can be adjusted to a larger one. Further, when finishing the storage of the helmet 61 stored by such a method, the user rotates the four toroids of the one engaging portion 63a to the unlocked state according to a predetermined number, The cylinder of the other engaging portion 63b is taken out from the cylinder opening of the one engaging portion 63a. Thereby, the helmet 61 finishes storage in the hook member F, and the user locks the one engaging portion 63a and the other engaging portion 63 on the back side of the helmet 61, and The lock member 63 is fixed on the surface of the helmet body 62 by the lock member holder 64 as necessary. In addition to the case of storage, when the one engaging portion 63a and the other engaging portion 63b are locked on the back side of the helmet 61 as shown in FIG. A finger can be put into a closed space formed by the helmet body 62 and the lock member 63, and the helmet 61 can be easily carried.
