  Hereinafter, an embodiment of an amphibious special vehicle according to the present invention will be described in detail with reference to the accompanying drawings. Needless to say, the present invention is not limited to the following examples, and various modifications can be made without departing from the spirit of the present invention.

  First, the structure of the amphibious special vehicle according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.

  The amphibious special vehicle according to the present embodiment is capable of surface navigation and land travel, and is used for disaster countermeasures and the like. As shown in FIG. 2, a driver's seat space 2 of the amphibious special vehicle 1 is formed with an entrance / exit 3, which is a hole that allows a driver to enter and exit, and an entrance / exit hatch 4 is installed at the entrance / exit 3. ing. In addition, as shown in FIG. 1, the edge part of the entrance / exit 3 is formed with the protrusion part 10 which protrudes from the surrounding outer plate member 5 to the vehicle outer side (upper side in FIG. 1).

  The amphibious special vehicle 1 is provided with an entrance hatch 4 as an entrance / exit opening / closing device for closing the entrance / exit 3 to ensure water tightness during water navigation. The entry / exit hatch 4 includes a disk-shaped hatch door 20, a hinge 30 for opening and closing the hatch door 20, an opening / closing handle 40 for manually operating the opening / closing of the hatch door 20, and an opening / closing handle 40. And a seal member 60 for improving the water tightness of the entrance / exit hatch 4.

  The hatch door 20 is attached to the vehicle outer side of the outer plate member 5 via a hinge 30 and is opened to the vehicle outer side of the amphibious special vehicle 1 (two-dot chain line in FIG. 1). An opening / closing handle 40 is rotatably supported on the inner side of the hatch door 20 (the lower side in FIG. 1). The opening / closing handle 40 includes an annular handle portion 41, a shaft portion 42 installed at the center of the handle portion 41, and a disk-shaped arm attached to the other end side of the shaft portion 42 in parallel with the handle portion 41. Part 43.

  In this embodiment, the boarding hatch 4 is provided with a pressing mechanism so that the driver can open and close the boarding hatch 4 from the inside of the vehicle. The pressing mechanism is a mechanism in which the hatch door 20 is fixed on the vehicle outer side when the driver performs an opening / closing operation of the passenger hatch 4 on the vehicle inner side.

  As shown in FIGS. 3 and 4, a plurality of (four in this embodiment) handle arms 50 are supported on the edge at equal intervals on the arm attachment portion 43 of the opening / closing handle 40, and the arm attachment portion 43. It is installed to extend in the tangential direction.

  When the handle portion 41 of the opening / closing handle 40 is gripped and rotated, both the shaft portion 42 and the arm attachment portion 43 rotate (see FIG. 1). As shown in FIGS. 3 and 4, the handle arm 50 supported by the arm mounting portion 43 is pulled by the rotation of the arm mounting portion 43, and is tangential to the arm mounting portion 43 (the axial direction of the handle arm 50). Moved. That is, the rotational movement of the opening / closing handle 40 is converted into the linear movement of the handle arm 50.

  In this embodiment, as shown in FIG. 5, the arm mounting portion 43 and the handle arm 50 are formed with engaging holes 43a and 50a, respectively, and the engaging pins 70 are passed through the engaging holes 43a and 50a, thereby mounting the arm. The portion 43 and the handle arm 50 are pin-coupled. Thereby, the rotational movement of the opening / closing handle 40 can be converted into the linear movement of the handle arm 50.

  For example, as shown in FIG. 3, when the arm mounting portion 43 is rotated to the right, the handle arm 50 supported by the arm mounting portion 43 moves so as to be pulled inside the hatch door 20, and as shown in FIG. When the arm attachment portion 43 is rotated counterclockwise, the handle arm 50 supported by the arm attachment portion 43 moves so as to be pushed to the outside of the hatch door 20.

  Of course, the structure for converting the rotational movement of the opening / closing handle 40 into the linear movement of the handle arm 50 is not limited to the pin connection as in this embodiment. For example, instead of the arm mounting portion 43 in the opening / closing handle 40, as shown in FIG. The rotational motion of the pinion gear 44 (corresponding to the rotational motion of the opening / closing handle 40) may be converted into the linear motion of the handle arm 50 and the rack gear 51.

  When the opening / closing handle 40 is turned and the handle arm 50 is moved so as to be pulled inside the hatch door 20, the seal member 60 fixed to the handle arm 50 is pressed against the protrusion 10 at the entrance / exit 3 of the outer plate member 5. . By pressing the handle arm 50 and the seal member 60 against the protrusion 10 with a predetermined pressing force, the hatch door 20 is reliably closed and the water tightness of the driver's seat space 2 is improved. Of course, when the hatch door 20 and the protrusion 10 at the entrance 3 are in close contact with each other by tightening with the handle arm 50 to ensure watertightness, the seal member 60 may not be installed.

  In the present embodiment, the boarding hatch 4 includes an explosion mechanism so that the driver can quickly get off the amphibious special vehicle 1 in an emergency or the like. The explosion mechanism is a mechanism that blows off the hatch door 20 instantaneously by detonating a predetermined explosive and secures an escape route for the driver.

  An explosive 80 is provided as a predetermined explosive in the explosive mechanism in the entrance / exit hatch 4 of the amphibious special vehicle 1 according to the present embodiment. The explosive 80 is installed between the hinge 30 and the outer plate member 5, and is connected to the lead wire 90. The ignition wire 90 is connected to an ignition device (not shown), and an ignition device is operated by operating an emergency escape switch (not shown), so that the ignition wire 90 is ignited. The fire of the ignited lead 90 is transmitted to the gunpowder 80, and the gunpowder 80 explodes. Explosion of the explosive 80 can destroy the seal member 60 together with the hinge 30 and blow the hatch door 20 to the outside of the vehicle.

  When the explosive 80 explodes, the hinge 30 and the seal member 60 that fix the hatch door 20 are installed on the outside of the vehicle. There is nothing. That is, in the amphibious special vehicle 1 according to the present embodiment, the driver is not injured by the explosion mechanism of the entry / exit hatch 4, and the vehicle can get off safely and quickly.

  Of course, the installation location of the gunpowder 80 is not limited between the hinge 30 and the outer plate member 5 of the present embodiment. However, if the gunpowder 80 is installed inside the amphibious special vehicle 1, the driver may be injured. Therefore, the gunpowder 80 is installed outside the amphibious special vehicle 1. For example, you may install the gunpowder 80 in the vicinity of the seal member 60 between the hatch door 20 and the outer plate member 5. Even if the explosive 80 is installed in the vicinity of the seal member 60 and exploded, it is an explosion on the outside of the amphibious special vehicle 1, and the projecting portion 11 of the entrance / exit 3 serves as a barrier to explode the explosive of the explosive 80. And no explosive fragments enter the inside of the amphibious special vehicle 1.

  In addition, as an explosion mechanism, it is necessary to install the explosive 80 so that the explosive 80 and the explosive piece due to the explosive of the explosive 80 do not enter the vehicle inside the amphibious special vehicle 1 as the explosive mechanism. For example, a gunpowder installation hole (not shown) is formed on the hinge 30 from the outside of the vehicle to install the gunpowder 80, and the gunpowder installation hole is sealed with a gunpowder lid (not shown) so that the gunpowder 80 does not get wet during water navigation. By installing the gunpowder 80 in this way, the gunpowder 80 is in a state of being able to explode reliably without getting wet with water even when navigating on the water, and in the event of an explosion, the hinge 30 is destroyed and the hatch door 20 and gunpowder (not shown). By simply blowing off the lid, the blast and explosive fragments resulting from the explosion of gunpowder 80 do not enter the inside of the amphibious special vehicle 1.

  In addition, the explosion mechanism in the entrance / exit hatch 4 is not limited to the explosive of the present embodiment. For example, the hatch door 20 may be blown off by causing an explosion with combustible gas or compressed air. However, in consideration of securing a space for loading gas cylinders and the like and increasing the vehicle weight, it is preferable to use explosives as in this embodiment.

  In this embodiment, an electric circuit (not shown) for detonating the explosive 80 is assembled in a separate system from an electric system (not shown) in the amphibious special vehicle 1. Thereby, even if the amphibious special vehicle 1 breaks down, the gunpowder 80 can be detonated and the hatch door 20 can be blown away, and the occupant can get off from the entrance 3.
