Abstract

(57) [Summary] [Purpose] Prevents the rotation of the support legs of the height-adjustable floor panel from locking and prevents the height from changing. [Structure] A screw cylinder (2) is joined to a through hole (31) provided in a floor panel (A), and a support leg (1) is screwed into the screw cylinder. The lower end of the support leg (1) has a knurled groove (1
3), which is press-fitted into the elastic support (4). To adjust the height of the floor panel above the floor, apply a screwdriver to the tool hook (12) at the top of the support leg and rotate. The knurled groove (13) at the lower end of the supporting leg firmly fixes the elastic support and the supporting leg, and prevents the elastic support from loosening and changing the height.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a support leg capable of adjusting the height of a floor panel.

[0002]

[Prior art]

  Conventionally, as the supporting leg capable of adjusting the height of the floor panel, the one shown in FIG. 2 is known. (See, for example, Japanese Utility Model Laid-Open No. 53-40631). In FIG. 2, the floor panel ( A) is supported on the floor (B) by a support leg (01) so that its height can be adjusted. Ie support The legs (01) are bolt-shaped with screws on the outer circumference, and the upper end is fitted with a rotary tool for height adjustment. A section (05) is provided. The lower end is inserted into the hole provided in the elastic support (04). ing.

[0003]   On the other hand, the floor panel (A) is provided with a through hole (03). The nut with support plate (02) is attached to the bottom of the The floor panel (A) is placed on the floor (B) surface by screwing the screws of the plate nut (02). To support.

[0004]   To adjust the height of the floor panel from the floor (B) side, install it on the upper end of the support leg (01). By rotating the support leg on the tool hook (05) that has been Can be performed by screwing the lock nut (02 ') into the support leg (01). The nut (02) and the floor panel height from changing. It has stopped.

[0005]

[Problems to be solved by the device]

  By the way, in the conventional technology as described above, the loosening prevention is performed every time the height is adjusted. The nut (02 ') must be loosened and tightened, and the lock nut (02') ') Is loose, the support leg (01) and nut (02) are loosely screwed together due to vibration. It is said that slippage occurs between the support leg (01) and the elastic support (04), and the height changes. It was inconvenient.

[0006]

[Means for Solving the Problems]

  In order to solve the above-mentioned inconvenience, the present invention has a through hole provided in a floor panel. A screw cylinder such as a nut with a collar is joined to the screw cylinder, and a support leg having a rotary tool hanging portion is attached to the screw cylinder. In the support leg that is screwed in and the elastic support is pressed into the lower part of the support leg, Support leg of floor panel characterized by knurled groove at the bottom I made it   Also, as the rotation stop of the elastic support, increase the area of the lower surface of the elastic support. , Providing a large number of protrusions on the lower surface of the elastic support or fixing the lower surface and the floor surface with an adhesive Configurations can also be employed.

[0007]

[Action]

  A screw cylinder is joined to a through hole provided in the floor panel, and the support leg is attached to the screw cylinder. Is screwed in. The lower end of the support leg is a knurled groove, It is press-fitted.   To adjust the height of the floor panel from the floor, place the driver on the tool hook on the top of the support leg. Apply iver and rotate. The knurled groove at the lower end of the support leg allows elastic support. The holding body and the support legs are firmly fixed, and the height does not change due to loosening.

[0008]

【Example】

  FIG. 1 shows an embodiment of the present invention.   The floor panel (A) is supported on the floor (B) surface by the support legs (1) in a height-adjustable manner. ing. That is, the support leg (1) is provided with a screw (11) on the outer circumference in a bolt shape, Is provided with a rotary tool hanging portion (12) for height adjustment. At the bottom, there is a low A hole provided in the upper part of the elastic support (4), which is provided with a let-shaped groove in the axial direction. (5) It is gently pressed into the inside.

[0009]   The elastic support (4) is made of, for example, an elastic synthetic resin, and the lower part has a conical shape. It has an enlarged portion (6) to increase the contact area with the floor (B). Also on the bottom surface Is provided with a large number of protrusions (7) to prevent the elastic support (4) and the floor (B) from rotating. It is supposed to stop.

[0010]   On the other hand, the floor panel (A) is provided with a through hole (3). From the side, a screw cylinder (2) such as a nut with a collar is joined.   Screwing the screw (11) of the support leg (1) with the screw provided around the screw cylinder (2) Thus, the floor panel (A) is supported on the floor (B) surface. Also, A surface plate or carpet (C) is placed on the upper surface of the lower panel (A).

[0011]   To adjust the height of the floor panel from the floor (B) side, install it at the upper end of the support leg (1). Rotate the support leg (1) using the screwdriver, for example, on the provided tool hook (12). Can be done by.

[0012]   The knurled groove (13) provided at the lower end of the support leg (1) is Since it is pressed into the hole (5) provided in the upper part of 4), after adjusting the height, the support is Prevents the legs (1) from rotating and prevents them from loosening, and the height of the floor panel changes. Prevent crossing.

[0013]   A conical enlarged part (6) is provided at the bottom of the elastic support (4), or under the elastic support (4). By providing a large number of protrusions (7) on the surface, rotation of the elastic support (4) and the floor (B) surface can be prevented. It is possible to prevent and prevent the loosening effect after adjustment more effectively. Also, elastic support If the lower surface of the holding body (4) and the floor (B) surface are fixed with an adhesive, the rotation of the elastic support body (4) is completed. Prevented entirely.

[0014]

[Effect of device]

  The present invention has the following effects. (a) It is said that a knurled groove is provided at the lower end of the support leg and press fit into the hole of the elastic support. With a simple structure, it is possible to prevent the support legs from loosening after the height adjustment. (b) If a conical enlarged part is provided at the bottom of the elastic support, the loosening prevention effect will be more effective. Can be carried out (Claim 2). (c) If many rotation-preventing projections are provided on the lower surface of the elastic support, the loosening prevention function will be improved. It can be performed more effectively (Claim 3). (d) If the lower surface of the elastic support is fixed to the floor with an adhesive, the rotation of the elastic support will be perfect. (Claim 4).
