Description

[Detailed Description of the Invention] This invention relates to a device for connecting members such as wood or stone.

Conventionally, as a connecting device for members 1, 1, as shown in FIG. 1 or 2, an insertion hole 5.5 for inserting a dowel 4 into abutment portions 2, 2 of a pair of members 1, 1 is used. There was one in which dowels 4 were inserted into the insertion holes 5, 5 to connect them.

However, with this coupling device, a gap is likely to be formed between the abutment parts 2, 2 of the pair of members 1, 1, and it is difficult to completely join the pair of members 1.1 at the abutment parts 2, 2 of the member 1.1. was difficult.

Therefore, both ends 1a, 1a of the pair of members 1, 1 at the abutment portions 2, 2 are fixed with a ribbed edge 10, etc., and the members 1, 1
The gaps between the joints of the parts were hidden, and the joints of the members 1 and 1 were reinforced.

Further, as shown in FIG. 3, by forming continuous lateral grooves 3, 3 in the abutment parts 2, 2 of the pair of members 1, 1, respectively, and inserting the yam nuts 6 into these lateral grooves 2, 2. Parts 1, 1
Devices that connect the two have also been used in the past.

However, even with the above coupling device, the pair of members 1, 1
It is not possible to completely join the members 1 to 1, and if the members 1 and 1 are pulled in the opposite direction to the joint of the members 1 and 1, they easily come off.

In other words, this connecting device only serves to hide the gap at the joint of the members 1, 1 and to prevent the connected members 1, 1 from deflecting at the joint of the members 1, 1. be.

Therefore, the connecting device according to the present invention provides a connecting device for members that incorporates the advantages of each of the conventional connecting devices described above and eliminates the drawbacks of each of the conventional connecting devices.

That is, according to the coupling device according to the present invention, it is possible to hide the gap formed between the abutment portions 2, 2 of the pair of members 1, 1, and it is also possible to withstand pressure in a direction perpendicular to the members 1, 1. , no bending occurs in the connected members 1,1.

This coupling device has the advantage that the members 1, 1 can be joined more firmly than conventional coupling devices.

Moreover, the pair of members 1 can be connected only by the connecting device according to this invention.
, 1 can be formed, and as a result,
This also has the advantage of saving materials used for connection and shortening the time required for connection work.

Hereinafter, this invention will be explained with reference to an embodiment shown in the drawings.A device for connecting members according to this invention continuously forms lateral grooves 3, 3 in abutment parts 2, 2 of members 1, 1,
, 3 are provided with insertion holes 5, 5 into which the dowel 4 is inserted; It consists of member 7.

The lateral grooves 3, 3 form the wing pieces 6 forming the connecting member 7.
It is necessary to form the groove at such a depth that approximately half of the blade 6 can be inserted therein.

Further, the insertion holes 5, 5 must also be shaped to a depth that allows approximately half of the dowel 4 to be inserted therein.

Therefore, this coupling device inserts the dowel 4 shaped on the coupling member 7 into the insertion holes 5, 5, and inserts the wing pieces 6 formed on the coupling member 7 into the lateral grooves 3, 3, respectively. It is formed by connecting a pair of members 1, 1.

As shown in FIG. 5, the connecting member 7 of this connecting device has a through hole 8 that penetrates the dowel 4 in a direction perpendicular to the dowel 4, and the wing pieces 6 are inserted into the through hole 8. But that's fine.

According to this connecting member 7, when connecting the pair of members 1, 1, the waist connecting member 7 is formed so that the dowel 4 is movable in the axial direction in the vertical direction of the wing piece 6, so that the horizontal groove 3 , 3 has the advantage that the dowel 4 can be quickly inserted into the insertion holes 5, 5 shaped like the dowels 5, 3.

Further, as shown in FIG. 6, it is preferable that the dowel 4 has a flange 9 formed at its distal end with a taper that widens from the base toward the distal end.

That is, with the dowel 4 formed in this way, when the dowel 4 is inserted into the insertion holes 5, 5, the respective members 1, 1 are inserted in the opposite direction to the connecting portion of the pair of members 1, 1. This is because dowel 4 will not come out even if you pull it.

Alternatively, the tip of the dowel may be shaped like a wedge as shown in FIG.

This invention has the above-mentioned configuration, and according to the device for connecting members according to this invention, the gap created at the abutment can be eliminated by the simple operation of inserting the connecting member into the members to be connected. In addition, since the dowel portion is disposed perpendicular to the abutment, it can withstand pressure in a direction perpendicular to the members to be connected, and the members do not bend.

In addition, since the dowel is movable in the axial direction of the blade portion, it can quickly adjust to the position of the dowel insertion hole of the member to be connected, resulting in extremely high work efficiency.

Furthermore, since the dowel is disposed perpendicular to the abutment, it does not need to be very long, resulting in material cost savings.
