Description

[Detailed Description of the Invention] The present invention relates to a blind member for dowel holes which is pre-processed to the size of each piece and backed up with a cushioning material whose driving depth can be adjusted.

For example, when laying floorboards or assembling furniture,
Doweling process is often used. As is well known,
In the doweling process, dowel holes are prepared in advance at the locations where nailing or screwing is desired, and the members are joined together by nailing or screwing into the dowel holes.
After that, a long and thin dowel material is driven into the dowel hole to close it.
After cutting off unnecessary parts, sanding is done to make the surface level with the surrounding area.This is a processing method that hides the heads of nails and screws and gives a beautiful finish to the surface. However, such a doweling process requires a lot of time and is extremely troublesome work, especially when there are a huge number of dowel holes, such as when laying floorboards over a wide area.

The object of the present invention is to provide a blind member for dowel holes which eliminates the above-mentioned drawbacks such as leveling by cutting and sanding, and which allows doweling processing to be performed extremely easily.

The blind member for dowel holes according to the present invention is machined in advance to a predetermined size one by one, and as is clear from the embodiment shown in Fig. 1, the outer diameter is approximately equal to the inner diameter of the dowel hole. A cushion material 2 having a size that comes into pressure contact with the head of a nail or screw in the dowel hole when the dowel body is driven into the dowel hole is fixed to one end surface of the approximately cylindrical dowel body 1, and a cushion material 2 is fixed to the other end surface of the dowel body 1. A leveling plate-like body 3 having rigidity and having a wider area than the end face.
It has a structure in which it is removably attached.

It is preferable that the surface side of the dowel body 1 (the side to which the leveling plate member 3 is attached) is beautifully finished with the same material or color tone as the surface of the plate material to which it is driven. Also, on the back side (cushion material 2
It is preferable to provide a chamfer 1a on the peripheral edge of the side (the side to which the holder is fixed). This makes it easy to insert the dowel hole and prevents the peripheral edge of the dowel hole from collapsing. If the board into which the dowel hole blind member is driven is elastic, such as a wooden board, the dowel body 1
It is preferable that the outer diameter of the dowel body 1 is slightly larger than the inner diameter of the dowel hole, and in the case of non-elastic materials such as gypsum board, the outer diameter of the dowel body 1 is slightly smaller than the inner diameter of the dowel hole.

The cushion material 2 may be any material as long as it has some degree of compressibility, such as various types of rubber, felt, synthetic resin foam, etc. Any shape may be used as long as it does not protrude to the side beyond the dowel body 1, but the surface of the cushion material 2 should be in pressure contact with the head of the nail or screw in the dowel hole when it is driven in. Dimensions.

Next, the leveling plate member 3 may be made of any material as long as it has a certain degree of rigidity. For example, cardboard, synthetic resin board, etc. may be used. The shape may be circular, square, hexagonal, etc., as long as it protrudes laterally from the dowel body 1. The leveling plate 3 is removably attached to the surface of the dowel body 1, but the material (including adhesive) is selected so that no adhesive remains on the surface of the dowel body 1 after peeling off. is preferable. This leveling plate-shaped body 3
The dowel body 1 has a so-called leveling function of making the surface level of the dowel body 1 match the surface level of the surrounding plate material, and also has a function of protecting the surface of the dowel body 1 during driving.

Construction examples are shown in FIGS. 2A to 2C. This example shows a case where a decorative floor board material 6 with a surface decoration 5 is fixed to a fixed base material 7 with screws 8. The dowel holes 9 provided in the decorative floor board material 6 are used to secure screws. Next, as shown in FIG. 2A, the dowel hole blind member 10 according to the present invention is inserted into the dowel hole 9, and a hammer or the like is used until the lower surface of the leveling plate 3 comes into contact with the surface of the decorative floor board material 6. Type in. Thereafter, as shown in FIG. 2B, a sharp knife-shaped tool 11 is inserted between the leveling plate 3 and the decorative floor board material 6 to separate them (see FIG. 2C).

The lower surface of the cushion material 2 is pressed against the head of the screw 8,
In addition, the leveling plate body 3 allows the dowel body 1 to
The surface level of the surface can be properly aligned with the surrounding area. In addition, if there is a risk that the dowel hole blind member 10 may fall off depending on the material of the dowel body 1 or the surrounding plate material, adhesive may be injected into the dowel hole 9 in advance or the dowel body A thin layer of adhesive may be applied to the outer circumferential surface of 1. If an adhesive is used, the leveling plate 3 is peeled off after the adhesive has hardened and the dowel hole blind member 10 has completely adhered.

As mentioned above, in the present invention, on the upper end surface of the dowel body 1,
Since the leveling plate 3 is rigid, has a wider area than the end surface of the dowel body 1, and is removable, it is possible to drive the leveling plate 3 until the bottom surface touches the plate material. Due to the rigidity of the plate-shaped body 3, it exhibits resistance that makes it difficult to drive in any further, and at this time, the upper end surface of the dowel body 1 is flush with the surrounding plate material. Therefore, if the plate-like body 3 is peeled off, there is no need for subsequent leveling work such as cutting or sanding. Furthermore, the rigidity of the plate-like body 3 protects the important surface of the dowel body 1 from being damaged during driving. The fact that the above-mentioned special leveling work is not required means that
Particularly in flooring construction over a wide area, the greater the number of dowel holes, the greater the reduction in work time and labor, which can greatly contribute to labor savings.

In addition, since the cushion material 2 is sized so that it comes into pressure contact with the head of a nail or screw in the dowel hole when the dowel body 1 is driven into the dowel hole, the depth of the dowel hole and the type of screw, etc.
Even if the length from the surface of the plate material to the head of the screw etc. differs slightly depending on each hole due to tightening, etc., the slight difference in length is absorbed and the surface level of the dowel body 1 is adjusted to the surface of the plate material. It is possible to match the level.

Furthermore, one end surface of the dowel body 1 to which the leveling plate-like body 3 is attached is made to match the material, color tone, or pattern of the surface of the plate material by making the dowel body 1 from the leftover material of the plate material into which it will be driven. By adding a matching finishing configuration, the surface of the board after doweling can be beautifully finished. In addition, if the leveling plate 3 is made of a transparent material, the end surface of the dowel body 1 can be seen through with the leveling plate 3 attached. Even if the surface pattern of the board material has a directionality, it is now possible to easily match the direction of the surface pattern of the dowel body 1 and the surface pattern of the board material. Beautiful doweling can be applied to boards such as plastic-based composite flooring materials and simulated stone materials, which have a hard surface. You won't have to pick it up.
