Description

  The present invention relates to a railway-related equipment storage box.

The storage box for storing railway-related equipment is used with a lid that can be locked and opened from the viewpoint of security and maintainability. For example, a storage box that stores control equipment for track branching devices is installed near the branching device, and when inspection is performed, the lid is opened by the operator, so that the control devices inside the storage box are exposed and inspection work is performed. Workability is ensured. Further, after the inspection is completed, the lid is closed, and locking is performed so that the lid is not opened as necessary. Railway related equipment storage boxes may be arranged together due to equipment requirements. Adjacent storage boxes approach each other, interfere with adjacent storage boxes when the lid is opened, and have sufficient opening. There are some cases that cannot be obtained.
In response to such a problem, a storage box and a hinge that can ensure inspection workability by enabling the removal of the lid have been developed (see, for example, Patent Documents 1 and 2).

Japanese Patent Laid-Open No. 10-205199 JP-A-6-14386

However, the above prior art has a structure in which the lid can be removed only when the opening degree of the lid is a specific angle. For this reason, when it cannot be released to a specific opening degree by interfering with an adjacent storage box when the lid is opened, the lid cannot be removed as a result. Even in cases where it is not desirable to remove the lid due to security requirements, the lid can be easily removed when the lid opening is at a specific angle. It is not preferable for application to a box. Similar problems exist not only in storage boxes installed on the ground, but also in control equipment storage boxes mounted on railway vehicles, such as storage boxes for storing control equipment for track branching devices. To get.
The present invention has been made in view of the above problems, and the purpose of the present invention is to make it impossible or difficult if the removal of the lid is unnecessary in the railway-related equipment storage box, and when necessary. Therefore, it is easy to remove the lid appropriately.

FIG. 1 illustrates a railway-related equipment storage box to which the present invention can be applied, in which (a) is an AA longitudinal sectional view showing an open state of a lid, and (b) is an illustration of BB in which the lid is omitted. It is sectional drawing.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. Here, parts that are the same as or correspond to those in the prior art are denoted by the same reference numerals, and detailed description thereof is omitted.
As illustrated in FIG. 3, the railway-related equipment storage box according to the embodiment of the present invention includes a box body 12 having an opening 12a and a lid 14 covering the opening 12a. The lid 14 is applied to a storage box that is rotatably connected by a hinge 16. Railway-related equipment 18 is accommodated in the box body 12, and these are exposed by opening the lid 14, and necessary maintenance is ensured.
In the example of FIG. 3, the hinge 16 is arranged at the upper end of the box body 12 so that the rotation axis extends horizontally, and the lid 14 is released so as to be flipped up. It is configured. However, the position of the hinge 16 is not limited to the illustrated example, and the hinge 16 may be disposed at the side end of the box body 12 or at the lower end of the box body 12 as shown in FIG.

In the embodiment of the present invention, as shown in FIG. 1, the hinge 16 has a bracket 20 fixed to the box body 12 side, a bracket 22 fixed to the lid 14 side, and a shaft 26. The fixing means 32 is provided. Here, the shaft 26 can be inserted into and removed from the brackets 20 and 22 in the axial direction regardless of the opening / closing angle of the lid 14 with respect to the box body 12. Further, the fixing means 32 makes it impossible to remove the shaft 26 from the brackets 20 and 22 by locking.
The brackets 20 and 22 illustrated in FIG. 1 have a prismatic block shape, and are each provided with an insertion hole for the shaft 26. And the shaft 26 is inserted in the state arrange | positioned so that both sides of the bracket 22 fixed to the cover 14 side may be inserted | pinched by the bracket 20 fixed to the box main body 12 side. Further, the shape of the brackets 20 and 22 is not limited to the example shown in FIG. 1 as long as it is appropriately supported by the shaft 26, but as shown in FIG. Further, a sheet metal part or the like obtained by bending a sheet material may be used.

  In the example of FIG. 1, a so-called padlock 24 is used as a component of the shaft 26 and the fixing means 32. Specifically, in the U-shaped latch of the padlock 24, the shaft portion that is attached to and detached from the lock main body 32 functions as the shaft 26. The U-shaped latch of the padlock 24 has a U-shape as a whole by a shaft portion 30 functioning as the shaft 26, a shaft portion 30 parallel to the shaft portion 30, and a curved closed end portion 28. A shaft portion 30 parallel to the shaft 26 is held so as to be able to protrude and retract with respect to the lock main body 32. Further, the closed end portion 28 as a stopper on one end side is fixed to the shaft 26, and the lock main body 32 as a stopper on the other end side is detachable from the shaft 26. By locking the lock main body 32, the lock main body 32 is arbitrarily fixed to a state where it is attached to the shaft 26. In the illustrated example, the lock body 32 is locked or unlocked by a key (not shown), but a so-called dial lock body may be employed.

Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained.
In the railway related equipment storage box 10 according to the embodiment of the present invention, a bracket 20 fixed to the box body 12 side and a bracket 22 fixed to the lid 14 side are axially attached by a shaft 26. Thus, the box main body 12 and the lid 14 are connected by a hinge 16. With this configuration, the lid 14 can be opened and closed with the shaft 26 of the hinge 16 as the center of rotation. Moreover, since the shaft 26 can be inserted and removed in the axial direction with respect to the brackets 20 and 22 regardless of the opening / closing angle of the lid 14 with respect to the box body 12, a sufficient opening degree cannot be obtained when the lid 14 is opened. Even in such a case, by removing the shaft 26 from the brackets 20 and 22 and removing the lid 14 from the box body 12, an open state similar to that in which the opening degree of the lid 14 is sufficiently obtained can be obtained. Therefore, it is possible to sufficiently ensure the maintainability of the railway related equipment 18 stored in the box body 12.

  The lid 14 removed from the box body 12 aligns the bracket 20 fixed to the body side 12 and the bracket 22 fixed to the lid side 14, and inserts a shaft 26 into each bracket 20, 22. Thus, it is pivotally attached to the box body 12. Further, by removing the shaft 26 from each bracket 20, 22 by locking the fixing means (stopper) 32, the lid 14 cannot be removed from the box body 12. For this reason, the embodiment of the present invention is preferable for application to railway-related equipment storage boxes from the viewpoint of tampering prevention measures. On the other hand, by releasing the locking by the fixing means 32, the lid 14 can be removed from the box body 12 as described above when necessary.

Further, stoppers 28 and 32 are disposed at both ends of the shaft 26. Among these, the stopper 28 on one end side is fixed to the shaft 26, so that the shaft 26 is pushed from one end side to the other end side ( Extraction from the brackets 20 and 22 in the direction from the left to the right in FIG. 1 is always impossible.
On the other hand, the stopper 32 on the other end side of the shaft 26 can be attached to and detached from the shaft 26 and can be arbitrarily fixed to the state where the stopper 32 on the other end side is attached to the shaft 26. For this reason, in the state where the stoppers 28 and 32 are disposed at both ends of the shaft 26, the shaft 26 cannot be extracted from the brackets 20 and 22. However, by releasing the locking by the fixing means 32 and removing the stopper (fixing means) 32 on the other end side of the shaft 26 from the shaft 26, the direction of pushing from the other end side to the one end side (from right to left in FIG. 1). The shaft 26 can be extracted from the brackets 20 and 22 in the direction of the head.

  Moreover, in the railway-related equipment storage box 10 according to the embodiment of the present invention, the components of the padlock 24 function as the shaft 26, the stopper 18, and the stopper (fixing means) 32. Accordingly, the bracket 20 fixed to the box body 12 side and the bracket 22 fixed to the lid 14 side are attached by a shaft portion (shaft) 26 on the side to be attached to and detached from the lock body 32 as a stopper. As a result, the box body 12 and the lid 14 are connected by the hinge 16. Further, the shaft portion 26 on the side to be attached to and detached from the lock main body (fixing means) 32 is pushed into the lock main body 32 and locked, thereby making it impossible to remove the shaft 26 from the brackets 20 and 22. At this time, it is impossible to remove the lid 14 from the box body 12. On the other hand, by releasing the lock by the lock main body 32, the lid 14 can be removed from the box main body 12 as described above.

FIG. 2 shows an application example of the embodiment of the present invention. In addition, about the same part as the example of FIG. 1, or a part corresponding, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.
In the example of FIG. 2, stoppers 128 and 130 that cannot be removed from the brackets 20 and 22 are disposed at both ends of the linear shaft 126. The stopper 128 on one end side has a disk shape larger in diameter than the shaft 126 and is fixed to the shaft 126. The stopper 130 on the other end side is a prismatic block member that can be attached to and detached from the lock main body 132 out of the first through hole 130a for inserting the shaft 126 and the U-shaped latch of the padlock 124. A second through hole 130b for inserting the shaft portion 132a is provided. The first through hole 130a and the second through hole 130b are formed to be orthogonal to each other and offset from each other in the radial direction of the hole. Further, a groove 126 a having a semicircular cross section is formed in the shaft 126 so as to cross in a direction orthogonal to the axial direction of the shaft 126.

Then, in a state where the shaft 126 is inserted through the first through hole 130a of the stopper 130, the groove 126a and the second through hole 130b coincide. In this state, the shaft portion 132a of the U-shaped latch of the padlock 124 is inserted into the second through hole 130b of the stopper 130. As a result, the shaft portion 132a of the padlock 124 and the groove 126a of the shaft 126a mesh with each other, and the stopper 130 is prevented from coming off from the shaft 126. Therefore, it will be understood that the same effect as the example of FIG. 1 can be obtained in the application example shown in FIG.
In addition, as a means for locking the stopper 130 detachably attached to the linear shaft 126 by locking, other means using the padlock 124 as shown in FIG. 2 can be adopted. For example, although detailed explanation is omitted, it is possible to use a stopper that clamps the shaft 126 and makes it impossible to release the clamp by locking, or a stopper that maintains the state inserted through the shaft 126 by locking.
