The holding wall 41b is formed so as to surround the virtual circle S (that is, the area on which the bottom of the fire extinguisher is placed), and in the present embodiment, the virtual circle S is inscribed on the inner circumference of the holding wall 41b.

The through holes 41c are formed at three positions along the width direction of the opening / closing member 40 and are arranged at positions capable of communicating with the through holes of the hinge 32, and are arranged on the rear side (arrow B side) of the lid portion 42. Will be done.

The notch portion 41d is formed by notching one end on the rear side (arrow B side) of the bottom plate 41a, and is formed along the outer surface of the holding wall 41b. The cutout portion 41d is a portion into which the side plate 34b is inserted when the second storage member 30 and the opening / closing member 40 are connected.

The lock pin 41e is formed so as to project from the lower surface of the bottom plate 41a and is arranged at a position corresponding to the fitting portion 33a so as to be able to be fitted with the fitting portion 33a.

The lid portion 42 is vertically connected to the end portion on the front side (arrow F side) of the bottom plate 41a, and has substantially the same dimensions as the front opening portion 21 of the first storage member 20 (that is, the front opening portion 21 has. It is a flat plate formed with a size to be covered), and the handle portion 42a is formed by folding back a plurality of upper ends thereof toward the front side.

The second holding member 43 includes a pair of projecting portions 43a formed so as to project from the back surface of the lid portion 42, and a recessed portion 43b formed between the pair of projecting portions 43a. The projecting portion 43a is formed in a flat plate shape and is arranged apart from each other in the width direction of the opening / closing member 40, and is in contact with the virtual circle S (that is, the side surface of the fire extinguisher) in the top view of the opening / closing member 40. It is formed by the length.

The recessed portion 43b is a portion recessed on the lid portion 42 side in the top view of the opening / closing member 40, and is formed by projecting the protruding portion 43a from the lid portion 42 in the present embodiment. The surfaces of the pair of projecting portions 43a facing each other and the back surface of the lid portion 42 between the facing surfaces are formed as recessed portions 43b (that is, formed in a U-shape when viewed from above the opening / closing member 40). Will be). Here, the projecting portion 43a extends from the upper surface of the bottom plate 41a to the upper side of the lid portion 42 from the vertical center (center of the standing height) of the lid portion 42, and the recessed portion 43b also extends in the same manner. It is formed continuously from the upper surface of the bottom plate 41a upward by the installation length.

Next, a method of using the fire extinguisher box 10 will be described with reference to FIGS. 5 and 6. 5 (a) is a top view of the second storage member 30 and the opening / closing member 40, and FIG. 5 (b) shows the second storage member 30 and the opening / closing member 40 in the Vb-Vb line of FIG. 5 (a). It is a sectional view. FIG. 6A is a cross-sectional view showing a state in which the opening / closing member 40 is opened from the state of FIG. 5B, and FIG. 6B is a fire extinguisher showing a state in which the opening / closing member 40 is opened. It is a side view of the box 10. In FIG. 5, for ease of understanding, the hatching of the hinge 32 and the lock member 33 is omitted, and the through hole 34c is omitted. Further, in FIGS. 5 and 6 (a), the outer shape of the fire extinguisher is schematically illustrated by a two-dot chain line.

As shown in FIG. 5, in a state where the opening / closing member 40 is pivotally supported by the second storage member 30 via the hinge 32 and the lock pin 41e is fitted to the fitting portion 33a (the opening / closing member 40 is closed). A part of the mounting portion 41 is arranged above the bottom surface portion 31. That is, the dimension of the mounting portion 41 in the front-rear direction (arrow BF direction) of the opening / closing member 40 (second storage member 30) is formed to be larger than the dimension of the bottom surface portion 31. Therefore, the lower surface of the opening / closing member 40 is secondly stored by the hinge 32 on the front side of the mounting portion 41 in the front-rear direction and on the rear side of the connecting portion between the mounting portion 41 and the lid portion 42. It is pivotally supported at the upper end of the outer peripheral wall 31b of the member 30.

Since the side plate 34b (first sandwiching member 35a, 35b) is arranged (arranged apart) in the front-rear direction from the projecting portion 43a (second sandwiching member 43), the hose is accommodated between the facing portions. A possible space is formed. Therefore, the fire extinguisher with the hose hanging on the side surface can be sandwiched by the pair of first sandwiching members 35a and 35b and the second sandwiching member 43.

In this case, the first holding members 35a and 35b are formed from flat plates provided with arcuate holding surfaces 35a and 35b1, and the first holding members 35a and 35b are arranged so as to be separated from each other in the vertical direction of the holding wall 34. Since the fire extinguisher is sandwiched, the cost of parts can be reduced as compared with the case where, for example, an arcuate sandwiching surface is continuously formed above and below the sandwiching wall 34. Further, since the first holding members 35a and 35b are formed in a rib shape on the holding wall 34, the strength of the holding wall 34 is improved. That is, since the first holding members 35a and 35b also serve as a member for holding the fire extinguisher and a member for ensuring the strength of the holding wall 34, the number of parts is reduced.

Further, the fire extinguisher is sandwiched by forming the second sandwiching member 43 from a pair of flat plate-shaped projecting portions 43a and arranging the pair of projecting portions 43a so as to be separated from each other in the width direction of the opening / closing member 40. Therefore, for example, the component cost can be reduced as compared with the case where the arc-shaped sandwiching surface is continuously formed over the upper and lower sides of the lid portion 42. Further, since the second holding member 43 is continuously formed from the lower part of the lid portion 42 to the upper side of the lid portion 42, the strength of the lid portion 42 is improved. That is, since the second holding member 43 also serves as a member for holding the fire extinguisher and a member for ensuring the strength of the lid portion 42, the number of parts is reduced.

As shown in FIG. 6A, the operation portion 33b is operated from the state of FIG. 5B to release the fitting between the fitting portion 33a and the lock pin 41e, and the opening / closing member 40 is moved around the axis of the hinge 32. When rotated to, the fire extinguisher rotates together with the opening / closing member 40. That is, since the mounting portion 41 side (in the present embodiment, the lower surface of the mounting portion 41) is pivotally supported by the second storage member 30, the opening / closing member 40 is rotated around the axis to be rotated in FIG. As shown in (b), the fire extinguisher is exposed from the first storage member 20, and the fire extinguisher can be arranged at a position where it can be easily taken out. Further, the fire extinguisher can be stored in the fire extinguisher box 10 by rotating the opening / closing member 40 on which the fire extinguisher is placed and storing it in the first storage member 20. Therefore, the fire extinguisher can be easily taken in and out, and the workability of filling or sending the load is improved.

Here, the opening / closing member 40 is pivotally supported by the second storage member 30 on the rear side (internal side of the first storage member 20) of the connecting portion between the mounting portion 41 (bottom plate 41a) and the lid portion 42. Therefore, the center of gravity of the fire extinguisher can be brought closer to the axis of the hinge 32 as compared with the case where the mounting portion 41 (bottom plate 41a) and the lid portion 42 are vertically supported. That is, since the moment due to the load of the fire extinguisher can be reduced during the opening / closing operation (rotation) of the opening / closing member 40, the opening / closing member 40 can be easily opened.

Further, since the second holding member 43 of the opening / closing member 40 is formed with a recessed portion 43b that is recessed toward the lid portion 42 side in the top view of the opening / closing member 40, the opening / closing member 40 is opened. Even in the state, the fire extinguisher can be held by the second holding member 43. Therefore, it is possible to prevent the fire extinguisher from falling from the lid portion 42 during the opening / closing operation of the opening / closing member 40.

Further, since the recessed portion 43b is continuously formed from the lower portion of the lid portion 42 (that is, the upper surface of the bottom plate 41a) to the upper side of the lid portion 42, the fire extinguisher is stored when the fire extinguisher is stored. Can be slid while being engaged with the second holding member 43 and mounted on the mounting portion 41. Further, since the second holding member 43 is continuously formed from the center of the lid portion 42 in the vertical direction to the upper side, the fire extinguisher is placed on the opening / closing member 40 (sliding along the second holding member 43). At that time, the fire extinguisher and the second holding member 43 can be easily engaged with each other. Therefore, the fire extinguisher can be easily taken in and out.

Further, a holding wall 41b is formed on the mounting portion 41, and the bottom surface of the fire extinguisher is held by the holding wall 41b. Further, the inner circumference of the holding wall 41b is in contact with the virtual circle S, and the recessed portion 43b is formed with a protrusion length in contact with the virtual circle S. That is, when the fire extinguisher is slid with respect to the second holding member 43, the bottom surface of the fire extinguisher is held by the holding wall 41b, and the position of the fire extinguisher when the opening / closing member 40 is closed is fixed by the holding wall 41b. Therefore, when the opening / closing member 40 is closed, the fire extinguisher can be reliably held by the first holding members 35a and 35b and the second holding member 43. Further, since the fire extinguisher is held by the holding wall 41b and the second holding member 43, it is possible to prevent the fire extinguisher from falling from the lid portion 42 when the opening / closing member 40 is opened / closed.

Further, since the lid portion 42 is formed in a flat plate shape, when the opening / closing member 40 is opened, the space between the opening / closing member 40 and the side surface of the first storage member 20 becomes an open surface, and the fire extinguisher is exposed on the open surface. Can be done. Therefore, the fire extinguisher can be taken in and out not only from above the opening / closing member 40 but also from the side.

In this case, the projecting length of the projecting portion 43a is preferably formed to be 1/8 or more and half or less of the radius of the virtual circle S, whereby the opening / closing member 40 is formed from the side. It is possible to achieve both the ease of putting in and taking out the fire extinguisher and the sliding function of the fire extinguisher in the second holding member 43.

Here, the opening operation of the opening / closing member 40 is regulated by the holding wall 41b coming into contact with the first holding member 35b. That is, the first holding member 35b is arranged on the locus of the relative displacement of the holding wall 41b with respect to the second storage member 30 (in the side view of the fire extinguisher box 10, the rear side of the holding wall 41b from the axis of the hinge 32). The distance from the axis to the front end of the first holding member 35b is formed shorter than the distance to the upper end of the first holding member 35b).

As a result, the displacement of the opening / closing member 40 can be regulated without separately providing a member for regulating the displacement of the opening / closing member 40. That is, since the first holding member 35b also serves as a member that holds the fire extinguisher when the opening / closing member 40 is closed and a member that regulates the displacement of the opening / closing member 40, the number of parts is reduced.

Here, when the relative displacement of the opening / closing member 40 with respect to the second storage member 30 is regulated, as an example, the second storage member 30 and the lid 42 (opening / closing member 40) are connected by a regulating member (for example, a chain). Can be considered. In this case, when the regulating member is connected to the upper portion or the side portion of the lid portion 42, the restricting member obstructs the opening and closing of the fire extinguisher from above or from the side of the lid portion 42 (opening / closing member 40).

On the other hand, according to the tank lorry 1 of the present embodiment, the displacement of the opening / closing member 40 is restricted by the contact of the first holding member 35b with the holding wall 41b (mounting portion 41), so that the second storage member 40 is stored. Compared with the case where the member 30 and the lid portion 42 are connected by a regulating member to regulate the displacement of the opening / closing member 40, the fire extinguisher is not hindered from being taken in and out from the open surface described above. Therefore, when the opening / closing member 40 is opened, the fire extinguisher can be easily taken in and out from both the upper and side opening surfaces of the opening / closing member 40.

Further, conventionally, since the opening / closing member is formed as a door that rotates 180 ° around a hinge (around a vertical or horizontal axis), a work space is required. That is, when the opening / closing member is opened / closed, the opening / closing member interferes with the fixtures adjacent to the fire extinguisher box, and the equipment necessary for filling and sending the load of the tank truck is operated with the opening / closing member open. It was difficult to take out the tool.

On the other hand, according to the tank lorry 1 of the present embodiment, since the opening / closing member 40 rotates to the front side of the fire extinguisher box 10, even if the opening / closing member 40 is opened, the fixture adjacent to the fire extinguisher box 10 The opening / closing member 40 does not interfere with 5. Further, in a state where the opening operation of the opening / closing member 40 is regulated by the first holding member 35b, the upper end of the opening / closing member 40 (lid portion 42) is located above the lower end of the fire extinguisher box 10, so that the fire extinguisher box 10 Even if the fixture 5 is assembled below, it does not interfere with the fixture 5. Therefore, since the tool can be taken out from the fixture 5 and the device can be operated with the opening / closing member 40 open, the workability of filling or delivering the load is improved.

Although the present invention has been described above based on the above-described embodiment, the present invention is not limited to the above-described embodiment, and it is easy that various modifications and improvements can be made without departing from the spirit of the present invention. It can be inferred from.

In the above embodiment, the case where the recessed portion 43b is formed in a U shape by the surfaces of the pair of protruding portions 43a facing each other and the back surface of the lid portion 42 between the facing surfaces will be described. However, the present invention is not limited to this, and for example, in the top view of the opening / closing member 40, the lid portion 42 may be recessed in an arc shape.

In the above embodiment, the case where the recessed portion 43b is formed on the back surface of the lid portion 42 (that is, the recessed portion 43b and the back surface of the lid portion 42 are formed on the same plane) has been described, but it is not always the case. The present invention is not limited to this, and for example, the recessed portion 43b is separated from the lid portion 42 toward the first holding members 35a and 35b (with a thickness between the recessed portion 43b and the lid portion 42). It may be formed. In particular, when the diameter of the bottom surface of the fire extinguisher is larger than the diameter of the intermediate portion, the recessed portion 43b is separated from the lid portion 42, and the holding wall 41b corresponding to the diameter of the bottom surface of the fire extinguisher is placed on the mounting portion 41. It should be formed.

In the above embodiment, the case where the second holding member 43 is formed from the upper surface of the bottom plate 41a, that is, the case where the lower end of the second holding member 43 is located below the upper end of the holding wall 41b has been described. The present invention is not necessarily limited to this, and for example, the lower end of the second holding member 43 may be positioned above the upper end of the holding wall 41b. In this case, the second sandwiching member 43 is formed with an extension length of at least half the length of the lid portion 42 (fire extinguisher) in the vertical direction, and the center position of the second sandwiching member 43 in the vertical direction is set. , It is preferable to position the lid portion 42 below the center position in the vertical direction. As a result, when the fire extinguisher is slid with respect to the second holding member 43, it is possible to prevent the fire extinguisher from falling off from the lid portion 42.

In the above embodiment, the case where the holding wall 41b is formed of a rectangular plate (formed at a uniform standing height) has been described, but the present invention is not necessarily limited to this, and for example, the holding wall 41b is not limited to this. The height of a part of the rectangle may be increased. In this case, it is preferable to increase the height of the rear end of the holding wall 41b. As a result, the fire extinguisher can be more reliably guided to the holding wall 41b, and it is possible to prevent the holding wall 41b from obstructing the opening and closing of the fire extinguisher from the side of the opening / closing member 40.

In the above embodiment, the case where the virtual circle S is inscribed in the inner circumference of the holding wall 41b has been described, but the present invention is not necessarily limited to this, and for example, the inner circumference of the holding wall 41b is larger than the virtual circle S. It may be formed large.

In the above embodiment, the case where the holding wall 41b forms a square region and surrounds the virtual circle S has been described, but the present invention is not necessarily limited to this, and for example, the holding wall 41b forms a circular region. Alternatively, the virtual circle S may be surrounded by intermittently forming the square or circular holding wall 41b. Further, on the upper surface of the bottom plate 41a, a flat plate or an arcuate plate is erected at a position facing the second sandwiching member 43 with the virtual circle S sandwiched between the plate and the second sandwiching member 43. A configuration that surrounds the virtual circle S may be used.

In the above embodiment, the case where the opening / closing member 40 is pivotally supported by the hinge 32 on the lower surface of the bottom plate 41a (mounting portion 41) has been described, but the present invention is not necessarily limited to this, and for example, the mounting portion 41 or A convex portion protruding along the width direction is provided on the side surface of the lid portion 42, a concave portion to be recessed along the width direction is provided on the first storage member 20, and the convex portion and the concave portion are fitted. The opening / closing member 40 may be pivotally supported by allowing the opening / closing member 40 to be pivotally supported.

In the above embodiment, on the front side (arrow F side) of the mounting portion 41 in the front-rear direction and on the rear side (arrow B side) of the connecting portion between the mounting portion 41 and the lid portion 42. The case where the lower surface of the mounting portion 41 (bottom plate 41a) is pivotally supported has been described, but the present invention is not limited to this, and at least the mounting portion 41 side of the opening / closing member 40 is pivotally supported by the second storage member 30. Just do it. Examples of the mounting portion 41 side of the opening / closing member 40 include a joint portion between the mounting portion 41 (bottom plate 41a) and the lid portion 42, and a lid portion 42 in the vicinity of the continuous portion. That is, the shaft may be supported at an arbitrary position in the lower region of the opening / closing member 40. In this case, if the mounting portion 41 (bottom plate 41a) is pivotally supported on the rear side of the center in the front-rear direction (that is, on the rear side of the center of gravity of the fire extinguisher), the fitting of the lock member 33 and the lock pin 41e is released. Then, since the opening / closing member 40 is rotated by the weight of the fire extinguisher, the opening / closing member 40 can be easily opened.

In the above embodiment, the case where the displacement of the opening / closing member 40 is regulated by the first sandwiching member 35b has been described, but the present invention is not necessarily limited to this, and for example, a chain connecting the mounting portion 41 and the bottom surface portion 31. May be provided, or a member that regulates the displacement of the opening / closing member 40 (a member that comes into contact with the mounting portion 41) may be provided on the displacement locus of the mounting portion 41.

In the above embodiment, the case where the first holding members 35a and 35b and the second holding member 43 are formed of the plate-shaped member will be described, and the material thereof is not particularly limited, but for example, the second holding member. 43 may be formed from a resin having high lubricity (for example, fluororesin or polyacetal resin). This makes it easier to slide the fire extinguisher and prevents the fire extinguisher from being scratched. When the second sandwiching member 43 is formed of a resin having high lubricity, the first sandwiching members 35a and 35b are formed to have a thick plate thickness (thickness in the vertical direction) and are formed of a rubber-like elastic body. Is preferable. As a result, even when the second holding member 43 is formed of a resin having high lubricity (that is, when the fire extinguisher is easily slid with respect to the second holding member 43), when the opening / closing member 40 is closed. , The fire extinguisher can be firmly held by the first holding members 35a and 35b and the second holding member 43.
