Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to a mobile storage.

(Prior art) Conventionally, in the case of a mobile storage, for example, the ninth
Experimental table 101 as shown in FIG.
The storage 103 used in combination with the table 10 has casters 105 on the bottom as shown in the figure.
1, it can be easily moved and set to the right side, or to the left side (not shown).

The caster 105 is provided with a locking device 107 for restraining movement when the storage 103 is set.

In the lock device 107, by stepping on a lever 109 provided on the side of the caster 105 with the tip of the foot, the left and right support forks 111 are brought into strong pressure contact with the wheel 113, and the pressure force applies braking force to the wheel. It has a working structure.

(Problems to be Solved by the Invention) As described above, the operation of the locking device 107 for restraining or releasing the restraint of the caster 105 is performed for each caster 105, which is very troublesome. In particular, locking device 107
The lever 109 is located at the bottom of the storage 103 and is operated by inserting the tip of the foot between the floor P and the bottom, which is not desirable in terms of operability.

In this case, ensuring a large distance H from the bottom of the storage 103 to the floor P makes it easier to find the position of the lever 109, and also allows the tip of the foot to be inserted easily, which is very favorable from the standpoint of operability. However, the ground clearance of the storage compartment 103 increases,
Affects storage space.

For this reason, considering storage space, it is desirable to reduce the diameter of the caster 105 to keep the ground clearance low, and considering operability, it is desirable to increase the ground clearance. The storage space and the operability of the lock device 107 were in a contradictory relationship.

Therefore, the object of this invention is to provide a movable storage that can improve ease of assembly and storage space without impairing operability.

[Structure of the invention] (Means for solving the problem) In order to achieve the above object, in this invention, in a movable storage supported by front and rear casters, a A pair of left and right supporting legs are provided on the attached base plate and are always urged to contract by a biasing spring, and are vertically extendable and retractable. a first foot operation section that causes the caster to touch the floor;
The unit is provided with a drive mechanism that extends the supporting leg when the first foot operating section is actuated, and retracts the supporting leg when the second foot operating section is actuated, and the first and second foot operating sections protrudes forward from the main body of the storage compartment.

(Function) According to this mobile storage, since it is a unit, the drive mechanism can be retrofitted and can be easily attached to the storage. Also,
When the first foot operation section is operated with the tip of the foot, the drive mechanism becomes activated and extends the support leg. The supporting legs, which are in contact with the floor by extension, lift the front caster off the floor. As a result, the front of the storage is supported by the left and right support legs and does not move.

Next, when the second foot operation part is operated with the foot, the drive mechanism is switched from the activated state to the deactivated state, the supporting legs are contracted and separated from the floor surface, and the front caster comes into contact with the floor surface. This allows the storage to be moved. Further, the first and second foot operation parts can be easily operated, and the diameter of the caster can be reduced, so that the storage space can be expanded.

(Embodiment) Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 8.

In the figure, numeral 1 indicates a movable storage used in combination with a table 3 for experiments.

The main body of the storage 1 has four upper and lower drawers 5, 5,
5, 5 are respectively provided, and casters 7, 7, 9, 9 are provided on the bottom surface at two locations on the left and right sides of the front end side and two locations on the left and right sides of the rear end side, for a total of four locations.

A pair of left and right support legs 11, 11 configured as a unit are provided on the front end side of the bottom surface of the main body of the storage 1, respectively.

The support leg 11 is a sleeve 1 that is integrally fixed to a base plate 13 attached to the bottom surface W of the storage 1.
5, a cylindrical support 17 fitted into the sleeve 15 so as to be vertically movable, and a grounding portion 19 fixed to the lower end of the support 17 and in contact with the floor P. The grounding portion 19 is made of a material such as rubber, and the support body 17 is always urged upward by a biasing spring 21 interposed within the sleeve 15, as shown in FIG.

The operation of the supporting legs 11, 11 is controlled by drive mechanisms 23, 23.

The drive mechanism 23 can be switched between an operating state in which the supporting leg 11 is extended (solid line in FIG. 6) and an operating state in which the supporting leg 11 is contracted (solid line in FIG. 4). That is, a pair of first
Arms 25, 25 and a pair of second arms 27, 27
are arranged respectively, and the first arm 25 is connected to the first shaft 2.
It is rotatably supported on the support body 17 by 9 and has a V-shaped shape when viewed from the side.

One end of the second arms 27, 27 is rotatably supported by the tip of the first arm 25 and a second shaft 31, and the other end of the second arm 27 is rotatably supported by a third shaft 33. It is suspended. The second shaft 31 and the third shaft 33 have a continuous shape extending left and right, and the central portion of the third shaft 33 is connected to a bracket 35.
It is fixedly supported on the base plate 13 by.

On the other hand, the first arms 25, 25 of the left and right drive mechanisms 23, 23 are integrally connected by a connecting member 37, and a first
A foot operation section 39 is fixed. Therefore,
By operating the first foot operation part 39 (arrow A in FIG. 6), the second shaft 31 moves to the left restraint area beyond the dead center from the axis a passing through the third shaft 33. As a result, the drive mechanism 23 is brought into operation, and the extended state of the supporting leg 11 is ensured. Further, by operating the second foot operation unit 41 (arrow B in FIG. 7), which will be described later, the second shaft 31 is moved to the restraint release area on the right side of the axis a passing through the first shaft 29 and the third shaft 33. do. This allows the drive mechanism 23 to be released from operation.

Note that when the supporting leg 11 is extended, the grounding portion 1 of the supporting leg 11
When 9 touches the floor P, the front casters 7, 7
The extension stroke is set such that it floats about 2 mm above the floor P and the items stored in the storage compartment 1 do not incline significantly.

The second foot operation section 41 is arranged on the upper surface of the first foot operation section 39 , and the amount of forward protrusion is suppressed to be smaller than that of the first foot operation section 39 .
9. The second foot operation section 41 can be operated without any trouble in this order.

A rising wall 43 at the base of the second foot operation section 41 is rotatably supported by the third shaft 33 and is provided with a guide hole 45 . The guide hole 45 is connected to the third shaft 3

The second shaft 31 extends from one end of the guide hole 45 to the other end.
As shown in FIGS. 6 and 7, when the drive mechanism 23 is in the operating state, the second foot operation section 41 is maintained in a standby state.

The mobile storage 1 configured in this manner can be easily retrofitted by attaching the unitized base plate 13 to the bottom surface W of the storage 1. On the other hand, after moving and setting the table base 3, when the first foot operation part 39 is operated with the tip of the foot, the drive mechanism 23 is activated and the support leg 11 is extended. At this time, the second foot operation section 41 is in an operation standby state as shown in FIG. On the other hand, the support leg 11 whose ground contact portion 19 is in contact with the floor surface P due to extension causes the front casters 7, 7 to float above the floor surface P. As a result, the front of the storage 1 has left and right support legs 11, 1.
It does not move because it is supported by 1.

Next, the second foot operation section 41 in the standby state
When operated with the foot, the drive mechanism 23 switches from the activated state to the deactivated state, the supporting legs 11 contract and leave the floor P, and the front caster 7 moves away from the floor P.
come into contact with As a result, the front and rear casters 7, 9
Since it is in contact with the floor P, the storage 1 can be moved.

The storage 1 can be restrained or released by one-touch operation of the first and second foot operation parts 39, 41, and the casters 7, 9 can be controlled by the first and second foot operation parts 39, 41. Since it is independent from 41, it is possible to make it smaller. As a result, storage space can be expanded.

[Advantages of the Invention] As explained above, the mobile storage unit of this invention can be easily retrofitted by attaching the base plate to the bottom of the storage unit in places with limited bottom space, improving assembly. This does not affect the storage space. In addition, the first and second foot operation parts allow the storage unit to be easily restrained or released with a single touch, which is very favorable in terms of operability.
