And it attaches to the mounting board 28 and the reinforcement board 34 so that the nut 29b may be fastened to the volt | bolt 29a. That is, the anti-vibration rubber 29 is disposed so as to be able to support the mounting portion 33c of the mounting plate 28 from below with the reinforcing plate 34 interposed therebetween. Each is fixed immovable.

  As shown in FIGS. 4B and 4C and FIGS. 5A to 5H, the lock mechanism 31 includes a rod-like body 22b having a knob 22a attached to the upper end thereof, and the rod-like body 22b. An operation lever 22 constituted by a cam plate 23a made of a flat plate whose upper part is fixed on the side surface in the vicinity of the lower end thereof, and a predetermined interval in the length direction of the mounting plate 28 with respect to the operation lever 22 A cam plate 23b made of a flat plate, a link member 27 for connecting the cam plates 23a and 23b, a cam follower 26 and a shaft 24 attached to the cam plates 23a and 23b, a collar 25 attached to the cam follower 26, and a spring washer. 36a and a nut 36b are provided.

  Insertion holes 37a of the shaft 24 are provided in the base end portions of the cam plates 23a and 23b, and both ends of the shaft 24 are rotatably held in the fixed plate 30 with the both ends of the shaft 24 being inserted into the insertion holes 37a. A pair of support plates 38, 38 are erected. That is, the cam plates 23a and 23b are rotatably supported at the base end portions by the fixed plate 30 and can swing around the shaft 24 inserted through the insertion hole 36a.

The cam plates 23 a and 23 b are provided with an insertion hole 37 b of the shaft portion 26 a (see FIG. 5G) of the cam follower 26 at a predetermined distance from the insertion hole 37 a and a base end portion rotated by the fixed plate 30. An engaging portion 39 is formed on the side surface in the vicinity of the base end portion so as to come into contact with the fixed plate 30 when it is rotated to one side while being held so as to suppress the rotation.
In the cam follower 26, the shaft portion 26 a inserted through the insertion hole 27 a (see FIG. 5H) of the link member 27 with the collar 25 being externally inserted is inserted into the insertion hole 37 b, and further protrudes from the insertion hole 37 b. A nut 36b is fastened to the tip of the shaft portion 26a via a spring washer 36a, and is attached to the cam plates 23a and 23b.

  FIGS. 6A and 6B are schematic diagrams for explaining the operation of the lock mechanism 31, and the lock mechanism 31 is viewed from the connection portion 33b side of the mounting plate 28 in FIG. 3B. Represents. Moreover, Fig.7 (a) and FIG.7 (b) are DD sectional views taken on the line in Fig.3 (a). 7B shows a state in which the operation lever 22 is operated in FIG. 7A, and FIG. 6A shows a state of the lock mechanism 31 in FIG. 7A.

As shown in FIG. 6 (a), the cam plates 23a and 23b have the same distance between the centers of the insertion holes 37a and 37b, and the base end portion is rotatably held by the fixing plate 30. The engaging portion 39 is in contact with the fixed plate 30 when being rotated, and in this state, the angles formed with respect to the vertical direction of the straight line connecting the centers of the insertion holes 37a and 37b are equal to each other. Yes.
In this state, the vibration isolator 18 is provided with a distance L ₁ (see FIG. 4C) from the lower surface 30a of the fixed plate 30 to the upper surface 28a of the mounting portion 33a of the mounting plate 28 on the floor surface 35. It is configured to be equal to the depth h (see FIG. 4 (c)) of the hollow formed.

  In the state shown in FIGS. 6A and 6B, the outer peripheral surface 26 b of the cam follower 26 and the lower surface 28 b of the mounting portion 33 c are in contact with each other, so that the load of the mounting plate 28 is applied to the cam follower 26. However, as shown in FIG. 6A, when the engaging portion 39 is in contact with the fixed plate 30, the insertion holes 37a and 37b (see FIGS. 5A and 5B) in the cam plates 23a and 23b. Since the straight line connecting the centers of c) is inclined with respect to the vertical direction, the cam plates 23a and 23b are rotated in the direction of arrow E by the load of the mounting plate 28 applied to the cam follower 26. Torque is generated.

However, since the engaging portion 39 is in contact with the fixed plate 30, the cam plates 23 a and 23 b do not rotate in the direction of arrow E. In this case, the load of the mounting plate 28 is supported by the cam plates 23 a and 23 b instead of the vibration isolating rubber 29. Therefore, in the state shown in FIG. 7A, even if the ATM is placed on the upper surface 28a (see FIG. 4C) of the placement portion 33a of the placement plate 28, the ATM or the placement plate 28 is used. Is not supported by the anti-vibration rubber 29.
In this way, when the vibration isolation function of the seismic isolation device 18 is released, the vibration isolating rubber 29 is not compressed under the load of the ATM or the mounting plate 28, so the mounting plate 28 is lowered. A problem arises that a step is generated between the upper surface 28a and the floor surface 35 of the mounting portion 33a, making it difficult to remove the ATM from the mounting plate 28. Therefore, the seismic isolation device 18 is excellent in workability when removing or installing the device placed on the placement plate 28.

  As described above, in the state shown in FIG. 6 (a), torque is always generated to rotate the cam plates 23a, 23b in the direction of arrow E, so that it is opposite to the direction of arrow E. The cam plates 23a and 23b do not rotate in the direction. That is, in the seismic isolation device 18, since the function of the lock mechanism 31 is released and the seismic isolation function of the seismic isolation device 18 is unlikely to occur suddenly, safety during use is high.

If the operation lever 22 is operated, the vibration isolation function of the vibration isolation device 18 can be exhibited again as follows.
First, the knob 22a of the operation lever 22 is gripped to rotate the cam plate 23a in the direction opposite to the direction of arrow E. Accordingly, the cam plate 23b connected to the cam plate 23a via the link member 27 also rotates by the same angle as the cam plate 23a in conjunction with the cam plate 23a. For example, when the cam plates 23a and 23b are rotated until the straight line connecting the centers of the insertion holes 37a and 37b is parallel to the vertical direction, the state shown in FIG. 6B is obtained.

  In the state shown in FIG. 6B, the operation lever 22 is operated, and the cam plates 23a and 23b are moved in the direction of arrow E until the outer peripheral surface 26b of the cam follower 26 is separated from the lower surface 28b of the mounting portion 33c of the mounting plate 28. When it is further rotated in the opposite direction, the state shown in FIG. 7B is obtained, for example. In this case, the load of the mounting plate 28 is supported not by the cam plates 23a and 23b but by the vibration isolating rubber 29. Therefore, in the state shown in FIG. 7B, when ATM is placed on the upper surface 28a of the placement portion 33a, those loads are applied to the vibration isolating rubber 29. Will be demonstrated.

As described above, in the seismic isolation device 18 of the present invention, since an air spring is not used, the structure is simple and can be manufactured at low cost. Further, the load of the mounting plate 28 and the device mounted on the upper surface 28a is distributed to the two cam plates 23a and 23b, so that the frictional force generated between the cam follower 26 and the mounting plate 28 can be kept small. The operability of the lock mechanism 31 is good.
And the mobile store vehicle in which such a vibration isolator 18 was installed in the luggage compartment 2 has an effect that it is suitable for transportation of a small and lightweight device.

  In addition, the mobile store vehicle of this invention is not limited to the structure shown in the present Example, It can change suitably. For example, in the seismic isolation device 18, the mounting plate 33 may have a structure in which the mounting portions 33c and 33c are extended from both end edges in the width direction of the mounting portion 33a without providing the connection portions 33b and 33b. However, if the mounting plate 28 has the structure shown in the present embodiment, the distance between the lower surface 30a of the fixing plate 30 and the upper surface 28a of the mounting portion 33a is short. There is no need to provide a deep recess in the surface 35. That is, there is a merit that the upper surface 28 a of the mounting portion 28 can be easily adjusted to the height of the floor surface 35.

  In addition, the pair of fixing plates 30 and 30 can be a single plate having a size substantially the same as the placement plate 28. However, in the structure as shown in the present embodiment, the fixed plate 30, the vibration isolating rubber 29, and the lock mechanism 31 are disposed in the space below the mounting portions 33c and 33c of the mounting plate 28, and the whole is simple. Due to the structure, installation work on a vehicle or the like is facilitated. Therefore, the cost required for the work is reduced.

  Further, instead of attaching the cam follower 26 to the cam plates 23a, 23b, a structure in which a protruding receiving portion is provided on the cam plates 23a, 23b so as to support the lower surface 28b of the mounting portion 33c of the mounting plate 28 may be adopted. . However, if the structure as shown in the present embodiment is used, the frictional force generated between the cam follower 26 and the mounting plate 28 when the cam plates 23a and 23b are rotated can be kept small. The effect of improving operability is exhibited.

  Moreover, the vibration isolator 18 can also be used independently in the state fixed to the floor surface etc. of the building instead of mounting in a mobile store vehicle. Further, the mobile store vehicle may have a structure in which the entrance / exit is provided not only on the rear surface of the vehicle body but also on both the rear surface and the side surface or only on the side surface.

  The inventions described in claims 1 to 7 can be applied to all mobile store vehicles that are equipped with precision equipment for using services such as ATMs and that use a cargo room as a store. .
