The lid 3 is formed with the risers 17 and 17 adjacent to the bearing grooves 13 and 13, and the notch steps formed on the inner end faces of the risers 17 and 17 on the shaft support described later. The step portions 18 and 18 that come into contact with the portions are formed, and the lid urging portion 32 that flips up the lid 3 in the opening direction when the holding state of the lid 3 is released is provided.

The lid urging portion 32 of the illustrated embodiment has a structure utilizing the spring elasticity of a leaf spring. That is, after the second shafts 6 and 6 are positioned in the bearing grooves 13 and 13 of the lid body 3, holding plates 19 and 19 are placed on the surface side of the bearing grooves 13 and 13 with set screws 29 and 29. As shown in FIGS. 1 and 2, the holding plates 19 and 19 are screwed together so that the tip of the lid 3 automatically pops up at the same time as the locked state of the lid 3 is released. Leaf spring portions 20 and 20 are provided for this purpose. Therefore, when the holding state of the lid holding portion 31 is released, the open end of the lid 3 jumps upward due to the elastic force of the leaf spring portions 20 and 20, and the opening operation of the lid 3 can be smoothly performed. It becomes.

Of course, the lid urging portion 32 can use any elastic member such as a coil spring, a repulsive force of a magnet, and an elastic soft resin, in addition to the leaf spring described above.

Next, as described above, the shaft portion 4 connecting the base plate 2 and the lid 3 is composed of two shaft members, a long first shaft 5 and a pair of left and right second shafts 6 and 6. The first shaft 5 is held by the long shaft support portion 9 projecting along the upper surface of one side edge of the base plate 2 so as to be able to rotate at a certain angle, and is supported at both ends thereof. The shaft supports 22 and 22 are provided so as to be located outside the portion 9 so as to be substantially perpendicular to the central axis of the first shaft 5.

Further, as shown in FIG. 1, stoppers 23 and 23 are projected from the outer peripheral portion of the first shaft 5, and the shaft supports 22 and 22 of the stoppers 23 and 23 are the first shaft 5. It hits the corner of the flat ceiling portion in the shaft support portion 9 at a position of approximately 90 ° with respect to the axis, and acts to limit the rotation of the first shaft 5.

On the other hand, in the illustrated embodiment, the second shafts 6 and 6 have mounting holes 24 and 24 formed diagonally above the shaft supports 22 and 22 projecting from both ends of the first shaft 5. It is attached so as to be inserted inside to form an axis different from the axis of the first axis 5.
As described above, in the lid structure according to the present invention, the shaft portion 4 is connected to the base plate 2 on the double floor side via the first shaft, and the shaft portion 4 is connected to the base plate 2 via the second shafts 6 and 6. It is connected to the lid 3 and the positions of the second axes 6 and 6 with respect to the central opening 8 are changed by the rotation of the first axis 5.

As described above, the holding plates 19 and 19 have a cover portion for preventing the second shafts 6 and 6 from coming off from the bearing grooves 13 and 13 of the lid body 3, and the lid plate 3 has a cover portion. A leaf spring portion 20 constituting a lid urging portion that automatically flips up the tip of the lid 3 at the same time as the locked state is released is integrally provided. In the illustrated embodiment, the recess 27 for exhibiting the spring effect is formed in the corresponding portion of the lid 3 where the leaf spring portion 20 is located, and the portion 27 corresponds to the vicinity of the tip of the leaf spring portion 20. A contact portion 28 is provided on the peripheral edge portion of the central opening 8 of the base plate 2 so that the tip portion of the leaf spring portion 20 can come into contact with the peripheral portion.

Therefore, in a state where the lid 3 is held so as to close the central opening 8 of the base plate 2 by the lid holding portion 31, tension is applied to the leaf spring portion 20 constituting the lid urging portion 32. Since the second shafts 6 and 6 are located away from both ends of the shaft support portion 9, normally, the base portion of the lid 3 is lifted upward by the urging force of the lid urging portion 32. Become.

However, according to the lid structure according to the present invention, with the lid 3 locked, the notched steps 25, 25 of the shaft supports 22, 22 projecting from the left and right ends of the first shaft 5 And the stepped portions 18 and 18 formed on the end faces of the rising portions 17 and 17 formed adjacent to the bearing grooves 13 and 13 of the lid 3 come into contact with each other to form an interference state of the shaft portion 4. The rotation limiting portion 33 that limits the rotation range is configured, and the shaft portion 4 can be prevented from jumping up. The portion shown by the diagonal line in FIG. 5 is the interference portion.

In the illustrated embodiment, for convenience of assembly, the second shafts 6 and 6 have a structure of being inserted into the mounting holes 24 and 24 formed diagonally above the shaft supports 22 and 22, but they are assembled. Of course, if there is no particular problem in this case, the shaft supports 22 and 22 may be integrally projected at predetermined positions.

According to the lid structure according to the present invention, the lid 3 is locked by the lid holding portion 31 when the central opening 8 is closed, and the second shaft is locked by the rotation limiting portion 33 as described above. Since the rotation range of 6 and 6 is limited, it is possible to suppress the lifting of the base portion of the lid 3 (the connecting portion between the lid 3 and the shaft portion 4 and also the portion of the second shafts 6 and 6). ..

On the other hand, when the slide button 15 located on the surface of the lid 3 is slid to release the holding state of the lid holding portion 31, the leaf spring portion integrally provided on the holding plate 19 constituting the lid urging portion 32. Since the tip of the lid 3 is slightly opened upward by the elastic force of 20, the tip of the lid 3 is grasped and rotated to a position of about 90 ° about the axis of the first axis 5. Then, the stoppers 23, 23 protruding from the outer peripheral portion of the first shaft 5 hit the corners of the flat ceiling portion in the shaft support portion 9, and the rotation of the first shaft 5 is stopped. At the same time, as shown in FIG. 7, the rotation axis of the lid 3 shifts to the second axes 6 and 6 and is centered on the second axes 6 and 6 which are higher than the axis of the first axis 5. , The lid 3 can be laid down in a state parallel to the floor surface.

In this state, the stepped portions 18 and 18 formed on the end faces of the rising portions 17 and 17 provided adjacent to the bearing grooves 13 and 13 of the lid 3 are the first shafts 5. The rotation of the lid plate 3 is restricted by the contact portions 26, 26 of the shaft supports 22, 22 protruding from both ends, and the lid plate 3 is protected from excessive rotation.

As described above, according to the lid structure according to the present invention, when the lid is closed, the rotation limiting portion can effectively prevent the base of the lid from rising, and the holding state of the lid is released. Occasionally, the open end of the lid is surely lifted a little by the urging force of the lid urging portion, so that it is easy to open, and it is possible to provide floor products with extremely good usability.
Further, the shaft portion is functional on the double floor side via the first shaft (in this case, the base plate 2 is a part of the floor plate 1, but considering the usage situation of fitting it into the floor plate and integrating it). Is connected to the member on the double floor side) and is connected to the lid via the second axis, so that the position is higher than the axis of the first axis. It can rotate around the axis of the shaft as a base point, and a state almost parallel to the floor surface can be obtained.
Therefore, it is possible to prevent the peripheral edge of the lower end portion of the lid plate from coming into contact with the corner portion of the floor finishing material that stands up at a right angle and remaining protruding upward.

In the present embodiment, the case where the lid structure is applied to the floor plate 1 (floor supplies) attached to the opening formed in the floor plate of the free access floor has been described, but the present invention is not limited to this. , It may be applied to an outlet box, or it may be applied to a structure in which an opening formed on the floor surface of a free access floor is directly closed by a lid so as to be openable and closable. In particular, in the latter case, the lid 3 may be attached to the edge of the opening on the floor surface via the shaft portion 4 so as to be openable / closable (rotatable), whereby the same effect as that of the above-described embodiment can be obtained. It is a thing.

Further, in the present embodiment, the step portions 18, 18 formed on the end faces of the notched step portions 25, 25 of the shaft supports 22, 22 (shaft portion 4) and the rising portions 17, 17 (cover body 3). The present invention has described a case where the rotation limiting portion 33 that limits the rotation range of the shaft portion 4 (second shafts 6 and 6) is configured by abutting (or interfering with) the shaft portion 4. However, as long as the rotation range of the shaft portion 4 (second shafts 6 and 6) can be limited, it may be any part of the shaft portion 4 and the lid 3 that abuts (interferes with). .. Further, even if the rotation limiting portion is formed by providing the coil spring so that the open end side of the lid 3 is urged upward with respect to the second shafts 6 and 6. good.

Further, in the present embodiment, as shown in FIG. 7, the case where the upper surface of the lid 3 can be rotated to the extent that it comes into contact with the floor finishing material 100 (that is, about 180 °) has been described. The invention is not limited to this, and the rotation angle of the lid 3 with respect to the floor finishing material 100 may be appropriate according to the structure of the lid, the mode of use, and the like. For example, in the shaft portion 4, if the distance between the first shaft 5 and the second shaft 6 is set large, the upper surface of the lid 3 may be opened to the extent that it abuts on the floor finishing material 100. It is necessary to rotate 180 ° or more. Further, when the floor finishing material 100 to be used is thick, there may be a state where the lid 3 does not rotate 180 ° even if the lid 3 is opened. In that case, the lid 3 is further manually opened from the state where the lid 3 is opened. When pressed downward, the floor finishing material 100 may bend and the lid 3 may be rotated by 180 °.
That is, the present invention can exert its effect as long as it is a lid (cover structure) that is rotated by two axes regardless of the rotation range of the lid 3.

Further, in the present embodiment, the first axis 5 and the pair of left and right second axes 6 and 6 are used as the shaft portion having the first axis and the second axis that can rotate separately from the first axis. The case where the shaft portion 4 is applied has been described, but the present invention is not limited to this, and the present invention is not limited to this, and a configuration in which the floor plate on the double floor side and the lid can be connected via two shafts (or by two shafts). If the lid is rotatable, the shape and the like are appropriate, and the present invention limits the rotation range of the two shafts, for example, the shaft not connected to the floor plate side. It is possible to obtain the same effect as.
