Description

[Detailed description of the invention] (Field of industrial application) This invention is designed to route the cables of computers and other equipment installed on the double floor under the floor panel, which consists of a double floor called a raised floor. When cable holes are formed for cables to be routed out or air conditioning holes are made for air conditioning, equipment on double floors can be prevented from falling into these holes when the equipment on the double floors is moved due to earthquakes, etc. This concerns the prevention frame.

(Prior art) As a conventional fall prevention frame for this type of equipment, the
The one disclosed in Japanese Patent No. 57-32199 is known. This conventional fall prevention frame has the advantage that it can be simply fitted into a hole formed in the floor panel, but the size of the fall prevention frame cannot be changed on site, and the floor There was a problem in that the fall prevention frame had to be formed to match the size of the hole formed in the panel, or conversely, the hole formed in the floor panel. Moreover, the existing computer room did not have enough power to turn off the computers, so there was a problem in which additional work for the fall prevention frame could not be done.

(Problem to be solved by the invention) The present invention was made in view of such conventional problems. It is easy to change, can be installed by simply fitting into a hole formed in the floor panel, and can be easily added to an existing computer without turning off the power. The purpose is to provide a frame to prevent equipment from falling on the floor.

(Means for Solving the Problem) The device fall prevention frame for the double floor of the present invention which achieves the above object has the upper part of the frame board curved outward in a substantially inverted U-shape to form a protruding hook part. , 4 of the frame plate
Each sheet is cut to match the length and width of the hole formed in the floor panel, assembled into a rectangular plan shape that fits the hole in the floor panel, and inserted from above the hole in the floor panel. The projecting latching portion of each frame plate is brought into contact with the upper surface of the mouth edge of the hole in the floor panel to protrude above the floor surface, and the lower part of the frame plate is curved outward. It is something.

(Example) Hereinafter, an example of implementing the present invention will be described based on the drawings.

FIG. 1 is a plan view of a state in which the device fall prevention frame C of the present invention is installed in a hole (cable hole, air conditioning hole, etc.) B formed in a floor panel A constituting a double floor.

The hole B formed in the floor panel A is formed into a planar rectangular shape with an appropriate size depending on its use.

The equipment fall prevention frame C is assembled using four frame plates 1 into a planar rectangular shape that fits the hole B of the floor panel A, and is installed by fitting into the hole B of the floor panel A from above.

The frame plate 1 is made of a strong plate material that will not be damaged or deformed even if it is hit by equipment, and its upper part is curved outward in a substantially U-shape to form a protruding hook part 2, and the lower part is bent outward in a substantially U-shape. The cable protection portion 3 is also formed by bending the cable protection portion 3 outward in a substantially U-shape. The protruding latching portion 2 is used to maintain the frame plate 1, that is, the equipment fall prevention frame C fitted into the hole B of the floor panel A, and to prevent the feet (not shown) of the equipment from climbing over it. The upper part of the frame board 1 is curved outward in a substantially inverted U shape, and the lower end 2a thereof is brought into contact with and latched to the upper surface B' of the mouth edge of the hole B of the floor panel A. The cable protector 3 prevents the cable from being damaged by rubbing against the lower end of the frame plate 1 when the cable (not shown) of the device is led out under the floor, and also prevents the device fall prevention frame C from slipping upward. The lower part of the frame plate is curved outward in a substantially U-shape. At this time, the upper end 3a of the cable protection part 3
It is preferable that the distance from the bottom end 2a of the protruding hook part 2 to the bottom end 2a of the protruding hook part 2 be formed to be approximately the same thickness as the floor panel A as in the illustrated embodiment.

Then, insert the equipment fall prevention frame C into the hole B of the floor panel A.
When installing, first cut the four frame boards 1 to match the length and width of the hole B in the floor panel A,
These four frame plates 1 are assembled into a rectangular plane shape with L-shaped joints 4, and each frame plate 1 is fastened to the L-shaped joint 4 with screws 5 to form an equipment fall prevention frame C. The installation is completed by fitting the prevention frame C into the hole B of the floor panel A from above.

In addition, when adding construction to an existing computer room, etc., or when adjusting the length of each frame board 1 to the full length and width of hole B in floor panel A, each frame board 1 is attached to floor panel A. It is only necessary to assemble it with the joint 4 and screw 5 while assembling it into the hole B of , and insert the cord of the computer or the like into the device fall prevention frame C at that time.

(Effect of the invention) Since the device prevention frame for the double floor of the present invention is constructed in this way, it can be installed by simply fitting it into the hole formed in the floor panel from above, and the equipment installed on the double floor can be protected against earthquakes. Even if the product is moved, each protruding latching frame can completely prevent it from falling into the hole in the floor panel.

Moreover, the equipment fall prevention frame can be easily assembled and configured at the construction site without having to be configured in advance at a factory to match the size of the hole formed in the floor panel. It can be easily adjusted at the construction site depending on the size of the hole. Therefore, the size of the hole formed in the floor panel can be freely set, and at the same time, there is no need to prepare equipment fall prevention frames of various sizes in advance, making it easier to manage parts. Additionally, it is possible to easily add additional computers to an existing computer room without turning off the power to the computers.

Moreover, by curving the lower part of the frame plate outward, it is locked to the edge of the hole in the floor panel, and there is no possibility that the equipment fall prevention frame will accidentally slip out upwards.

Therefore, the intended purpose can be achieved.
