Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hammock connection structure in a helmet for detachably and firmly connecting and connecting a hammog body as an interior material to a helmet body.

[0002]

[Prior art]

 Conventionally, as a hammock connection structure in a helmet, a pair of hooks having an L-shaped cross section, which have a pair of left and right upper ends closed and a lower end open, are provided on the inner surface of the helmet body so as to face each other with a predetermined distance. On the other hand, at the mounting part made of a flexible and tough synthetic resin that is integrated with or integrated with the hammock, a narrow width part that matches the separation dimension of the left and right facing hook pieces is provided through the step parts on both sides. It is formed in a continuous manner, and a widened portion is integrally formed on the back surface of the narrow portion, and a small protrusion for preventing slip-out is provided on the back surface of the both sides directly above the step portion. , The widened part at the mounting part of the hammock is inserted between the left and right facing hooks on the inner surface of the helmet to be engaged and connected. The top of each facing hook The wider section forms to lock is configured not come off from the hook pieces of helmet body side by moving unnecessary to downward.

However, in such a configuration, when the hammock is connected to the helmet body after being assembled, various external forces are applied to the hammock, which strongly bends the upper part of the hammock attachment portion inward. If this happens, the small protrusions for preventing slip-out will inevitably also tilt backwards and backwards under these conditions. As a result, it is not possible to maintain the lock on the upper end surface of each of the left and right facing hook pieces, the loss prevention function is lost, and the hammock may come off from the engagement connection with the helmet body. there were.

[0004]

[Problems to be solved by the device]

 The present invention has been devised to solve the above-mentioned problems in the conventional hammock connection structure in this type of helmet, and the engagement connection of the hammock to the helmet may unnecessarily come off. It is intended to provide a hammock connection structure for a helmet that does not exist.

[0005]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. An L-shaped cross section in which the left and right upper ends of the helmet body 1 are closed and the lower ends are opened. -Shaped hook pieces 2, 2 are spaced apart from each other by a predetermined width and are opposed to each other, and are attached to a mounting portion 4 made of a flexible and strong synthetic resin which is integrally or integrally connected with a hammock 3 corresponding thereto. A narrow portion 5 is formed which fits the separation width of the left and right facing hook pieces 2 and 2. The back surface of the narrow width portion 5 is provided between the left and right facing hook pieces 2 and 2 on the inner surface of the helmet body 1. In the connection structure of the hammock in the helmet in which the widened portion 6 to be inserted is integrally formed, in the hammock 3, the locking arms 7, 7 are provided on the upper left and right sides of the narrow portion 5 of the hammock 3 downwards through the gap 8 or the break. On the helmet body 1 with the tips of the locking arms 7, 7 It is characterized in that it has configured to face the hook piece 2,2 upper end surface of the side.

[0006]

[Action]

 When the widened portion 6 of the mounting portion 4 of the hammock 3 is inserted into the left and right hooks 2 and 2 on the inner side surface of the hermetic body 1 through the lower end opening of the hammock 3 by the above-described means, the hammock 3 is engaged. The tips of the locking arms 7, 7 projecting downwardly on the left and right sides of the upper portion of the narrow portion 5 lock the hook pieces 2, 2 on the inner surface of the helmet body 1.

Here, when the upper part of the mounting portion 4 of the hammock 3 is strongly bent inward, the locking arms 7, 7 are left and right of the mounting portion 4 of the hammock 3 through the gap 8 or the break. Since the locking arms 7 and 7 are integrally projected downward on both sides, the locking arms 7 and 7 themselves can be tilted in a straight line without being bent, and the tips thereof are always hooked on the inner surface of the helmet body 1. It is possible to maintain the locked state by being located on the upper end surfaces of the second and second parts.

[0008]

【Example】

 A preferred embodiment of the present invention will be described with reference to the drawings. First, at a predetermined position on the inner surface of a hard synthetic resin main body 1, a cross section L having a pair of left and right upper ends closed and a lower end open. The character-shaped hook pieces 2, 2 are provided so as to face each other with a predetermined width apart.

Next, the fitting width 4 of the helmet body 1 is fitted to the mounting portion 4 of the flexible and tough synthetic resin hammock 3 which is fitted to the left and right hook pieces 2 and 2 of the helmet body 1. A narrowed portion 5 is formed, and a widened portion 6 for engaging between the hook pieces 2 and 2 is integrally formed on the back surface of the narrowed portion 5, and the narrowed portion 5 is formed on both left and right upper sides of the upper portion. The locking arms 7 and 7 for preventing slipping out are integrally projected downward through the gaps 8 and 8 or the slits, and the widened portion 6 at the mounting portion 4 of the hammock 3 is provided inside the helmet body 1. In the state in which the hook arms 2 and 2 on the left and right sides are inserted into and engaged with each other through the lower end opening, the tips of the locking arms 7 and 7 are hooks 2 and 2 on the inner surface of the helmet body 1. It is configured to face the upper end surface.

A hook hole 9 for hooking a chin strap can be formed in the lower portion of the mounting portion 4 of the hammock 3 as required, as shown by the chain double-dashed line in FIG. is there. Further, the mounting portion 4 of the hammock 3 may not be integrated with the hammock 3 but may be formed separately as a separate body so as to be combined and integrated.

[0011]

[Effect of device]

 The present invention is as described above, and in the hammock connecting structure in the helmet, the locking arms 7, 7 are integrally provided on the lower left and right sides of the narrow portion 5 of the hammock 3 so as to project downwardly through the gap 8 or the break. Since the tips of the locking arms 7 and 7 face the hook pieces 2 and 2 on the inner surface of the helmet body 1, when the upper portion of the mounting portion 4 of the hammock 3 is strongly bent inward. However, the locking arms 7 and 7 themselves are not bent and only incline in a straight state, and their tips are always located on the hook pieces 2 and 2 upper end surfaces of the inner surface of the helmet body 1. It has a practical effect such that it keeps the locked state, can always fulfill the function of preventing slipping out, and has a simple structure and is easy to implement.
