Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an improvement of equipment that can be freely drawn out and housed in a multi-tiered closed switchboard.

[Technical background of the invention and its problems]

2. Description of the Related Art Conventionally, devices such as an inverter and a disconnector (hereinafter referred to as drawer devices) that are housed in a closed switchboard are configured to be freely drawn out. That is, as shown in FIG. 1, the drawer device 1 has a handle 2 on the front upper part of the main body including the bow section, and a grip part 3a on the inside upper part of the handle 2.
A locking pin 3 whose lower end extends below the main body and locks at a predetermined position in the closed switchboard, an outlet 4 which projects toward the rear of the main body, and wheels 5 attached to the lower side of the main body. It was made up of 100 parts, and could be moved freely on the floor, stored in a closed switchboard, or pulled out.

By the way, when the above-mentioned drawer equipment 1 is of the same type and has the same rating, in the multi-tier closed switchboard 6 as shown in FIG. Every storage room in room 9 must be able to accommodate storage. In other words, compatibility was needed.

Therefore, it is easy to move on the floor and store or draw out the storage compartment 9 on the lower level, but when storing in the storage compartment 7 on the upper level, the handle 2 is in a high position, so you need to use a stepladder to move it. Similarly, since the lock pin 3 is located at a high position, a tool such as a stepladder is required to pull it up to unlock it from the lock groove 6a in the closed switchboard (indicated by the dashed line in the figure). Work tools were required and the work had to be carried out in unstable conditions.

Conversely, if the handle 2 is provided at the bottom of the main body,
Although it is easy to store in the upper storage chamber 7 and operate the lock pin 3, it requires an unnatural posture to move on the floor, store in the lower storage chamber 9, or operate the lock pin 3. Not.

[Purpose of invention]

The purpose of this invention is to facilitate the operation of multi-tier closed switchboards without the need for any work tools, regardless of whether the multi-tier closed switchboard is moved on the floor or when the multi-tier closed switchboard is stored in or pulled out. The goal is to provide equipment.

[Summary of the idea]

The present invention is characterized in that the length of the handle in the vertical direction is approximately equal to the height of the pull-out device, and that a grip portion is also provided protruding from the middle portion of the lock pin.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 4 and 5, a drawer device 10 provided with an outlet portion 4 and wheels 5 includes a handle 11 having a length approximately the same as the height of its main body.
A lock pin 12 has a grip portion 12a protruding from the upper inside of the main body, and a lock pin 12 whose lower end extends below the main body and locks at a predetermined position in the closed switchboard. Grip portions 14 protruding from the inner lower portions of 11 are provided, respectively.

Therefore, when moving on the floor, storing in the lower storage chamber 9, or pulling out a drawer, grasp the handle 11 in the same way as before or use the grip part 12a of the lock pin 12.
can be grasped and operated. Furthermore, in order to store or draw out a drawer in the upper storage chamber 7, a work tool such as a stepladder is required even if the drawer device 10 is placed in a high position by grasping the lower part of the handle 11 and the lock pin 12 grasping the grip portion 14. It can be operated without

[Other embodiments of the invention]

The present invention is not limited to the above-described embodiment, and the lock may be released by pulling out the grip instead of directly pulling up the lock pin.
That is, in FIGS. 6 and 7, the drawer device 20 to which the outlet portion 4 and the wheels 5 (not shown) are attached has a length that is approximately the same as the height of the main body portion and a grip portion of a lock pin, which will be described later. A handle 21 formed to a size that does not interfere with the drawer, this handle 2
A gripping portion 23 that penetrates through holes 22, 22 provided on the front surface of the main body inside the mounting portion of 1, and a spring 24 that constantly pulls this gripping portion 23 toward the inside of the main body.
A shaft 27 is supported at both ends by the closed switchboard, is connected to both ends of the grip 23 via links 25, and rotates counterclockwise in FIG. 6 when the grip 23 is pulled forward. A locking pin 29, which is connected via an integrally connected link 28 and which rises when the shaft 27 is rotated counterclockwise, is attached to each.

Therefore, when moving on the floor or storing into or pulling out from the storage chambers 7, 8, 9 of the closed switchboard, the same procedure as described above may be used. Further, when operating the lock pin, by grasping the grip portion 23 at an appropriate position and pulling it forward, the lock pin 29 is raised and unlocked from the closing switchboard.

[Effect of idea]

Since the present invention is configured as described above,
Although compatible, work tools such as a stepladder are required when moving on the floor, storing or pulling out storage compartments in each level of a multi-tier closed switchboard, and releasing locks within the storage compartment. This allows for easy and safe work.
