Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a fixing structure for a top plate in a washstand.

[Background technology]

When fixing the top plate 6, which is formed by installing a washing bowl on top of the top support base 7 such as the cabinet 7a, conventional methods include joining the two using metal fittings, using double-sided tape, etc. A method of adhering the two using an adhesive such as caulking material is used, but when the top plate 6 is large and the top plate 6 is fixed to the top plate support 7 during on-site construction, Gluing is not suitable, so a method using metal fittings is used.

The construction method using metal fittings is generally shown in Figures 6a and 6b. In Fig. 6a, the top plate 6 is made by molding resin such as artificial marble, and when the top plate 6 is molded, nuts 13 are inserted and fixed, and L-shaped coupling fittings 8 are attached to the cabinet 7a.
The connecting fitting 8 and the nut 13 are fixed by screwing to the inner surface of the side plate of the top plate support 7 formed by the The top plate 6 is fixed to the top plate support stand 7 via the top plate support base 7. However, in this case, when insert-molding the nut 13 into the top plate 6, it is necessary to be careful not to let the resin get into the threaded part of the nut 13.
It is necessary to devise a shape that makes it difficult for the nut 13 to come out from inside, which poses a problem in workability in processing and manufacturing. Also, in this case, if there are variations in the thickness of the top plate 6 and the distance between the nuts 13 and the coupling fittings 8 becomes too short, or if there are variations in the length of the bolts 9 and the bolts 9 are too long, Before the bolt 9 is tightened sufficiently, the tip of the bolt 9 may be attached to the nut 13.
There is also the problem that the top plate 6 gets stuck inside the top plate 6, causing problems in fixing the top plate 6. On the other hand, in FIG. 6b, the top plate 6 is made of wood, and the top plate support 7 is formed by a cabinet 7a.
By screwing the wood screws 14 into the top plate 6 from the coupling fitting 8 screwed and fixed to the inner side of the side plate,
The top plate support 7 is connected via the coupling fittings 8 and the wood screws 14.
The top plate 6 is fixed to the top plate 6. However, driving the wood screws 14 at the construction site in this way is time-consuming and poses a problem in workability at the site.

[Purpose of invention]

The present invention was developed in view of the above points, and has good workability without the need to insert nuts or use wood screws, and also eliminates variations in the thickness of the top plate and the length of bolts. The purpose of this is to allow the top plate to be fixed without any adverse effects.

[Disclosure of invention]

Therefore, the top plate fixing structure according to the present invention has side pieces 3, 3 protruding upward on both sides of the lower piece 2 provided with the female screw 1, with a dimension larger than the upward protrusion dimension of the female screw 1, and also on each side. Fixing pieces 4, 4 are extended outward from the pieces 3, 3 to form a fixing metal fitting 5, and the fixing piece 4 is connected to the lower surface of the top plate 6 to fix the fixing metal fitting 5.
The top plate 6 is placed on the top plate support 7, and the tip of a bolt 9 passed from below through the coupling fitting 8 attached to the top plate support 7 is screwed into the female thread 1 of the fixing fitting 5. The present invention will be described in detail below with reference to Examples.

As shown in FIG. 1c, the fixing fitting 5 includes fixing pieces 4, 4 having side pieces 3, 3 extending upwardly on both sides of the lower piece 2, and a through hole 15 provided at the upper end of each side piece 3, 3. The lower piece 2 is provided with a cylindrical internal thread 1 that is open at the top and bottom and has a thread formed on its inner periphery. This internal thread 1 is formed integrally with the lower piece 2 by a thread cutting method so that a separate member is not required. Further, the female thread 1 is formed to protrude toward the upper surface side of the lower piece 2, and the upward protrusion dimension of the side piece 3 is set to be larger than the protrusion dimension of the female thread 1. Further, the coupling fitting 8 is formed into a substantially inverted L shape with a horizontal piece 16 and a vertical piece 17, and through holes 18 and 19 are formed in the horizontal piece 16 and the vertical piece 17, respectively.

On the other hand, as shown in FIG. 1a, the top plate 6 is provided with a wash bowl 20 and is made of resin or the like, such as artificial marble, and serves as a wash counter.
Fixing metal fittings 5 are attached to both ends of the lower surface of this top plate 6 at four positions. For installation, the fixing pieces 4 were brought into contact with the bottom surface of the top plate 6 by passing the tapping screws 21 through the through holes 15 of the fixing pieces 4, 4 of the fixing bracket 5 and screwing them into the prepared holes formed on the bottom surface of the top plate 6. It is done in a state. Here, fixing metal fitting 5
In this case, the side piece 3 is larger than the upwardly protruding dimension of the female screw 1.
Since the upward protrusion is large, the upper end of the female screw 1 is located below the lower surface of the top plate 6, and a gap is formed therebetween. Incidentally, at this time, as shown in FIG. 1B, the fixing metal fitting 5 may be attached to a portion projected as a protrusion 22 from the lower surface of the top plate 6. Furthermore, if the material of the top plate 6 is not threadable, it may be bonded with an adhesive. In this way, the fixing fitting 5 provided with the female thread 1 can be attached to the top plate 6 without the need for inserting it into the top plate 6. The top plate support 7 is formed as a cabinet 7a having a storage section with a door 23, and coupling fittings 8 are attached at four locations to the upper ends of the inner surfaces of side plates 24 on both sides thereof. This installation is done by inserting the wood screw 25 through the through hole 19 of the vertical piece 17 of the coupling fitting 8.
This is done by screwing it into the side plate 24.

Then, as described above, the fixing metal fittings 5 are attached to the top plate 6, and the joining metal fittings 8 are attached to the top plate support base 7, and these are transported to a construction site, and the top plate 6 is attached to the top plate support base 7 at the construction site. As shown in Fig. 1b, the fixing work involves passing the bolt 9 through the through hole 18 of the horizontal piece 16 of the coupling fitting 8 from below.
This can be done by screwing the tip of this bolt 9 into the female thread 1 of the fixing metal fitting 5 to connect the fixing metal fitting 5 and the coupling metal fitting 8. In the figure, 26 is a washer. In this way, the top plate 6 can be fixed by tightening the bolts 9, and the work can be carried out without the need to drive in wood screws at the construction site. In addition, in this case, the thickness of the top plate 6 varies and the distance between the lower surface of the female thread 1 and the upper surface of the coupling fitting 8 becomes too short, and the length of the bolt 9 varies and the bolt 9 Even if the bolt 9 is too long, the tip of the bolt 9 will not get caught in the gap between the top end of the female thread 1 and the bottom surface of the top plate 6, and will not be stuck due to variations in the thickness of the top plate 6 or bolts. The top plate 6 can be attached without any trouble by absorbing variations in the length of the top plate 9.

In the above embodiment, the top plate support 7 is formed by the cabinet 7a, but as shown in FIG. 2, the top plate support 7 is formed by the curtain front plate set 7b. You can.

Figure 3a shows a mirror cabinet 28 that is attached to the wall above the location where the washstand is installed, and is formed by attaching a mirror 29 and a lighting fixture 30 to the front of a steel plate frame. It has been done. Flanges 31 and 32 are provided at the upper and lower ends of the rear surface of the mirror cabinet 28, respectively.The upper flange 31 has a pair of left and right square locking holes 33, and the lower flange 32 has a pair of square locking holes 33. One screw hole 34 is bored in each of the holes. Also wall surface 3
5, a pair of upper fixing metal fittings 38 and one lower fixing metal fitting 39 are attached to the upper and lower lower crosspieces 36 and 37 using wood screws 40 or the like. Upper fixing bracket 3
8 is provided with a locking protrusion 41 projecting upward, and the lower fixing metal fitting 39 is provided with a through hole 42. When attaching the mirror cabinet 28 to the wall surface 35 as shown in FIG. 3b, first open the locking hole 3 of the flange 31 as shown in FIG.
3, the locking protrusion 41 of the upper fixture 38 is inserted and locked so that the upper part of the mirror cabinet 28 is suspended from the upper fixture 38, and then the lower fixture 39 is inserted and locked as shown in FIG. 4b. A machine screw 43 passed through the through hole 42 from below is screwed into the screw hole 34 of the flange 32 to fix the lower end of the mirror cabinet 28 to the lower fixture 39. The mirror cabinet 28 can be attached to the wall surface 35 in this way, but if the wall surface 35 is to be finished with tiles, mortar 44 must be applied to the wall surface 35 after the mirror cabinet 28 is attached to the wall surface 35. If the mortar 44 is applied directly above the upper fixture 38, the flange 31 cannot be unlatched from the upper fixture 38, and the mirror cabinet 28
cannot be repaired or replaced. So wall 3
5, use a spacer 46 whose upper part is thicker than the total thickness of mortar 44 and tile 45 as shown in FIG. It is attached to the wall surface 35 above the fixture 38, and mortar 44 is applied to the wall surface 35 and tiles 45 are laid above the spacer 46. In this case, the spacer 46 is removably attached to the wall surface 35 by screwing a screw 48 into the wall surface 35 through a pilot hole 47.
By removing the mirror cabinet 28 from the wall surface 35, the upper side of the upper fixing bracket 38 can be opened. be.

[Effect of idea]

As mentioned above, in the present invention, on both sides of the lower piece provided with the female screw, side pieces are made to protrude upward with a dimension larger than the upward protrusion of the female screw, and each side piece is provided with a fixing piece outward. Extend to form a fixing fitting,
I attached a fixing piece to the underside of the top plate to secure the fixing bracket, and screwed the tip of the bolt that passed through the coupling bracket attached to the top plate support from below into the female thread of the fixing bracket. Fixing fittings with internal threads can be attached to the top plate without the need for insert molding into the top plate, and the top plate can be fixed by tightening bolts.
This allows work to be carried out without the need to drive wood screws at the construction site, and also prevents the gap between the bottom surface of the female screw and the top surface of the coupling fitting from becoming too short due to variations in the thickness of the top plate. Even if the length of the bolt varies and the bolt is too long, the tip of the bolt will not get caught in the gap between the top end of the female thread and the bottom of the top plate, and will not cause any problems. It is possible to attach a top plate.
