Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to floor outlets, floor plates,
The present invention relates to a mounting structure for a floor article, such as a blind plate, for inserting and engaging a floor article having at least a flange portion and a cylindrical portion into a floor-side member disposed under the floor of a building such as an office.

[Conventional technology]

OA equipment such as word processors, fax machines, office computers, and copiers has increased in offices.
Floor supplies such as floor outlets for supplying power to these OA devices are increasingly being installed on the floors of offices and other buildings.

Most of the mounting means are to form a female thread on the inner circumferential surface of a floor-side member installed under the floor of an office, and a male thread on the outer circumferential surface of a cylindrical part of the floor article. The structure was such that the cylindrical part was screwed into a female screw in the floor side member to be fixed. In addition, if the floor side members installed under the floor etc. are not parallel to the floor surface, the flanges of the floor equipment will not contact the floor surface evenly, so conventionally, a horizontal adjustment ring was installed on the floor side members to adjust the balance. I was trying to do that.

[The problem that the idea attempts to solve]

As described above, most of the conventional mounting structures for floor products have a structure in which the cylindrical part of the floor product is screwed into the floor side member and fixed.

Therefore, it is troublesome to rotate the floor equipment during installation, and in particular, the number of pitches of the male screws formed on the outer circumferential surface of the cylindrical part of the floor equipment is quite narrow, so the number of rotations becomes extremely large. There was a problem that the installation work was complicated, and the screw structure gradually loosened over the years of use.

In addition, since the cylindrical part of the floor equipment was designed to be screwed into the floor side member, in the case of a floor outlet, it was not possible to connect the power supply line under the floor in advance within the inner cylinder that housed the outlet. First, there was a problem that the wire connection work etc. after screwing was completed became more complicated.

Furthermore, to adjust the horizontal balance,
As mentioned above, in the past, a horizontal adjustment ring was attached to the floor side member, but even with this, there are cases where balance cannot be maintained, and there is a slight difference between the flange of the floor equipment and the floor surface. There was a problem when a gap occurred.

Therefore, the present invention provides a coil spring that is biased downwardly in the floor side member that receives the cylindrical part of the floor product, and uses the elastic force of the coil spring to push the cylindrical part of the floor product downward. By providing a mounting structure for flooring products in which the flange portion of the flooring product is forcibly pulled against the floor surface and the flange portion of the flooring product is brought into even contact with the floor surface by this tensile force, the above-mentioned conventional structure can be improved. The purpose is to eliminate the problems associated with this.

[Means to solve the problem]

In detail, the structure of the present invention to achieve the above object is as follows: A floor outlet-like structure comprising at least a flange portion that contacts the floor surface and a cylindrical portion connected to the lower surface of the flange portion. In a floor equipment mounting structure for inserting floor equipment into a floor side member such as an outlet box disposed under the floor of a building, a downward elastic force is applied to the floor side member. A coil spring is attached so that the coil spring has an elastic force, and the elastic force of the coil spring is used to pull the cylindrical part of the flooring product downwards, and this tensile force evenly spreads the flange part of the flooring product on the floor surface. This is a mounting structure for floor equipment, characterized in that it is configured so as to come into contact with the floor equipment.

The number of cutouts 17 to be formed is sufficient if they are formed in two places to pass at least two engagers 4, 4, but as shown in FIG. 2, they are formed in four places with a phase shift of 90 degrees You may do so.

The guide posts 8 are fixed using screws 18 or the like so as to hang down from the lower surface of the cover plate 7, and in the illustrated embodiment, four guide posts 8, 8 are provided at predetermined intervals around the large diameter hole 16. , 8, 8 are provided protrudingly. Small diameter portions 19, 19 are formed at the upper portions of two diagonally arranged portions (FIG. 9).

The coil spring 9 has a large diameter that can be wound around the outer periphery of the guide posts 8, 8, 8, 8 protruding from the lower surface of the lid plate 7, and preferably has a larger diameter at the top than at the bottom. The one that is done is good.

Next, the elevating ring 10 has a
It is provided with a spring receiving groove 20 for receiving the lower end of the coil spring 9 described above, and as shown in FIGS. A through hole 21 is formed. Furthermore, cutouts 22, 22 are formed on the inner peripheral edge of the elevating ring 10 to correspond to the engagers 4, 4 protruding from the cylindrical portion 3 of the floor article 1. As mentioned above, two engaging elements 4 are provided protruding from the lower end of the cylindrical part 3 with a phase shift of 180 degrees.
Although it is sufficient to form the notches 22 at two locations correspondingly, they may also be formed at four locations with a phase shift of 90 degrees as shown in the figure.

On the back side of the lifting ring 10 provided with the spring receiving groove 20, as shown in FIGS. Locking sides 25 for the control ring 11, which will be described later, are protruded from the hanging wall 24 at predetermined intervals.

Next, the control ring 11 is locked by a locking piece 25 protruding from the hanging wall 24 of the control ring 10, and is rotatably mounted on the back side of the lifting ring 10. , as shown in FIGS. 7 and 8, the guide posts 8, 8,
A notch 26 is formed for passing the wires 8, 8 through.
The notch widths of two notches 26', 26' on the diagonal line of this notch part 26 are smaller than the other two notch widths (26>26'). Relatively large curved notches 27, 27 are formed at one end of the notches 26', 26'. In other words, the guide post 8 is the same as the normal notch 2.
6, 26 and the relatively large notches 27, 27 formed in the narrow notches 26', 26', it is possible to move up and down along the guide post 8 together with the elevating ring 10. However, when the guide post 8 is located in the narrow notches 26', 26', the notches 26', 26' are engaged with the small diameter part 19 formed in the guide post 8, and the vertical direction is Sliding is regulated. Therefore, it goes without saying that the thickness of the control ring 11 is somewhat thinner than the height of the small diameter portion 19 formed in the guide post 8.

In addition, in order to forcibly rotate the control ring 11 using the engagers 4, 4 that protrude laterally from the lower end of the cylindrical portion 3 of the floor article 1, the front surface of the control ring 11 is rotated 90 degrees at a time. It is formed by protrudingly forming engaging portions 28 which are cut and raised on both sides with a phase shift.

This engaging portion 28 is connected to the control ring 10.
It is in a state of being locked by a locking piece 25 so as to be located on a thin step portion 23 formed on the back side of the cover.

The floor products and floor side members used in the mounting structure of the floor products of the present invention have the above-mentioned configuration, and the housing 6 forming the floor side member 5 is positioned below the mounting hole provided in the floor surface 29 (under the floor). It is fixed in advance. A coil spring 9 is positioned between a cover plate 7 fixed to the upper surface of the housing 6 and a spring receiving groove 20 provided in the control ring 10. Since the cover plate 7 side is the fixed side of the coil spring 9, it has a biasing force directed downward (towards the bottom of the floor).However, before the floor equipment 1 is inserted, the guide post 8 , 8 are engaged with the narrow notches 26', 26' formed in the control ring 11 (in this case, the narrow notches 26', 26' are (becoming an engaging portion), the downward biasing force of the coil spring 9 is kept in a compressed state (FIG. 10).
In this state, the engaging parts 28, 28 formed on the front side of the control ring 11 are connected to the notches 22, 22 formed in the elevating ring 10 and the notches 17, 17 formed in the cover plate 7. It is in a state that is consistent with the above.

Next, when inserting a floor article 1 such as a floor outlet, grasp the flange portion 2 of the floor article 1, and insert the engaging element 4, which is provided laterally protruding near the lower end of the cylindrical portion 3, into the floor article 1. 4, control ring 11

1), the elevating ring 10 is instantaneously pressed toward the bottom of the floor by the elastic force of the compressed coil spring 9. At this time, the engaging elements 4, 4 protruding from the cylindrical part 3 of the flooring product 1 are engaged with the stepped part 23 formed on the back surface of the elevating ring 10, so that the Cylindrical part 3 of article 1
Together with the lifting ring 10, the coil spring 9 is pulled downward under the floor by the elastic force of the coil spring 9, and the upper flange portion 2 contacts the floor surface 29 evenly, so that the elastic force of the coil spring 9 is restricted. It becomes a state of being
This completes the insertion of the floor article 1.

In addition, when using the mounting structure of the present invention, the floor equipment 1 can be removed from the floor side member 5 after being mounted. That is, when the floor article 1 is pulled up upward against the elastic force of the coil spring 9 and rotated slightly counterclockwise, the engager 4 protruding from the cylindrical portion 3, 4 rotates the control ring 11 counterclockwise to engage the small width notches 26', 26' of the control ring 11 with the small diameter parts 19, 19 of the guide post 8. Then,
When the engaging parts 28, 28 and the notches 22, 22 formed in the lifting ring 10 are aligned in this locked state, the engaging elements 4, 4 are released from the step parts 23, 23 of the lifting ring 10. , which can be easily pulled upward.

As shown in the figure, it is sufficient to form the control portions in the control ring 11 only in two of the four notches located on the diagonal line.
Of course, it may be formed in all the individual notches. In addition, as described above, four notches 17 are formed in the cover plate 7 at positions shifted by 90 degrees, and four notches 22 and 4 are also formed in the elevating ring 10 and the control ring 11 to correspond to the four notches 17. By providing the respective engaging portions 28, the cylindrical portion 3 of the floor article 1 can be inserted into the floor side member 5 with the position changed by 90 degrees, and as a result, the floor of the office etc. In cases where a large number of floor outlets are installed on a surface, it is also possible to align the positions of all the outlets in the same direction.

[Effect of idea]

Since the mounting structure of the floor product of the present invention has the above-described configuration, the flange portion of the floor product can be brought into even contact with the floor surface by the elastic force of the coil spring, unlike conventional floor products. It is possible to solve problems caused by a gap between the floor surface and the flange part.

In addition, instead of being screwed into the floor side member of the cylindrical part of the flooring product as in the past, it uses crimping using a coil spring, so if the flooring product gradually becomes loose due to aging after insertion, It is possible to solve any problems that may arise. Furthermore, on-site construction requires no screwing work at all, and the flooring equipment can be crimped instantly with just a slight rotation, making on-site work extremely easy.

In addition, when using the mounting structure of the present invention, there is no need to provide a conventional screw hole in the flange of the floor product, and if the floor product is a floor outlet, the power supply cable under the floor and the inside of the inner tube must be connected in advance. As a result, there is no need to provide a screw hole on the top surface of the inner cylinder lid.
