Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting device for mutually fixing vertical members and cross members such as a column and a cross member, a vertical stile and a horizontal stile, etc.

<Prior art> There are various devices for attaching horizontal members to vertical members.
The technology shown in Figure 4 is one of them. According to this prior art, a plurality of screw holes 4 are provided in the left and right sleeve plates 3 of a U-shaped fixture 2 fixed to one side of a column 1, and the side ends of the crossbars are formed on the outside of the fixture 2. The insertion hole 6 provided in the cross member is connected to the screw hole 4.
If you insert the screw 7 in line with the column material 1 and the cross member 5,
The structure is such that they are joined together.

<Problems to be solved by the invention> The prior art described above has the disadvantage that the head of the screw 7 inserted from the outside of the cross member 5 becomes unsightly because it is visible from the outside, and that the head of the screw 7 inserted from the outside of the cross member 5 is unsightly. Multiple screw holes 4
It takes a lot of trouble to match the screw hole 4 and the insertion hole 6 of the cross member, so the work efficiency is poor, and the screw hole 4 and the insertion hole 6
If they are formed in a discrepancy, they will not match and it will be difficult to insert the screws. Since this technique involves the attachment 2 engaging the inside of the crosspiece 5, it is suitable for cases where the crosspiece is a hollow rectangular tube, but it is suitable for joining solid bodies such as wood or narrow It has become unsuitable for frames.

<Means for solving the problem> This invention was proposed in view of the existing situation.
That is, inclined stepped portions 3 are formed on the upper and lower left and right sides of the vertically long main metal 2 fixed to the horizontal member 1, and wedge pieces 7 each have arm portions 8 protruding from the upper and lower ends of the main metal 2 to intervene in the inclined stepped portions 3,
A screw rod 9 having a head 10 inserted from the upper wedge piece 7 is inserted with a margin into the shaft hole 5 of the main metal, and the lower part of the screw rod 9 is inserted into the lower wedge piece 7'.
The main metal and the wedge piece are located inside the lip groove-shaped vertical frame 12 of the vertical member 11, and the bent end 13 of the vertical frame is pressed by the wedge piece. It is intended to provide a device for attaching a crosspiece to a longitudinal member which does not have the disadvantages mentioned above by being drawn towards the crosspiece.

<Operation> To attach the horizontal member 1 to the vertical member 11, first, the horizontal member is lowered from above the vertical member and the main metal 2 is positioned within the vertical frame 12. At this time, the rear surfaces of the upper and lower wedge pieces 7, 7' come into contact with the bent end portion 13 of the vertical frame 12. When the cross member 1 is positioned, the screw rod 9 is rotated to press the wedge pieces 7, 7' against the main metal 2. In other words, the screw rod 9 inserted from the upper wedge piece 7 has its lower end engaged with the screw hole 7b of the lower wedge piece 7', so that the screw rod 9 is inserted through the upper wedge piece 7.
As the lever rotates, the lower wedge piece 7' rises and the upper wedge piece 7 descends together with the screw rod, so that each arm part 8 of the wedge pieces 7, 7' touches the inclined step part 3 of the main metal 2. When the screw rod 9 is further rotated, the wedge pieces 7, 7' move toward the bent end 13 of the vertical frame under the restriction of the inclined step 3 and press against the bent end. The pressed bent end 13 is drawn toward the cross member 1, and
Therefore, the vertical frame 12 and the main metal 2 are connected via the wedge pieces 7, 7', so that the cross member 1 is attached to the vertical member 11.

<Example> 1 is a horizontal member, and a vertically elongated main metal 2 is attached to the side end portion. The vertically elongated main metal 2 has inclined step portions 3 formed on the left and right sides of the upper and lower ends, and a tunnel-shaped shaft hole 5 is formed on the center axis. The main metal 2 is fixed to the cross member 1 by inserting a screw 6 through this leg-shaped base. 7,
Reference numeral 7' designates wedge pieces that are disposed opposite to the upper and lower ends of the main metal 2, each of which has arm parts 8 protruding from each other having an inclined part intervening in the inclined stepped part 3 of the main metal. The screw rod 9 inserted through the hole 7a passes through the shaft hole 5 of the main metal and is screwed into the screw hole 7b of the lower wedge piece 7'. The head 10 of this screw rod 9 is located on the upper surface of the upper wedge piece 7 and can be rotated from above with a screwdriver, and since the shaft hole 5 has a deep groove shape, the screw rod 9 has a margin in the shaft hole 5. It is inserted through. Reference numeral 11 denotes a vertical member that is in contact with the horizontal member 1, and a vertical frame 12 having a rip groove cross section is fixed in the vertical groove 11a with screws 14, and the main metal 2 and the wedge pieces 7, 7' are mounted within the vertical frame. The bent end 13 of the vertical frame 12 is located on the rear surface of the wedge pieces 7, 7', and the bent end 13
A gap 15 exists between the cross member 1 and the cross member 1.

That is, when the tip of a screwdriver (not shown) is applied from above to the screw head 10 and rotated, the lower wedge piece 7' which is threadedly engaged with the lower end of the screw rod rises, and the arm 8 moves to the inclined stepped portion at the lower end of the main metal. 8, and along with this, the arm portion 8 of the upper wedge piece 7 also intervenes and contacts the inclined step portion 3 at the upper end. When the screw rod 9 is further rotated, the arm part 8 in contact with the inclined step part 3 is pressed and retreated, and the bent end part 13 on the rear surface is pushed back.
pressure weld. There is a gap 15 between the bent end and the cross member 1.
exists, so the pressed bent end 13 is connected to the cross member 1
As a result, the main metal 2, the wedge pieces 7, 7', and the bent end 13 are firmly connected, so that the cross member 1 is immovably attached to the vertical member 11.

In the above embodiment, the vertical frame 12 is separate from the vertical member 1, but it is also possible to configure the vertical frame to also serve as the vertical member, and the shaft hole 5 of the main metal can be formed into an elliptical shape. Although the base 4 does not have an arm shape, such a configuration is of course within the scope of the present invention.

<Effect of invention> The present invention exhibits the following unique effects.

(1) When the screw rod is rotated, the bent end of the vertical frame is pressed by the wedge piece and automatically connects to the vertical main metal, firmly joining the horizontal members to the vertical members, making installation quick and easy. It will definitely be done.

(2) The main metal and wedge piece are located within the vertical frame, and the screws are rotated from above the vertical and horizontal members (the lower device is from below), so the device is not visible and has an outstanding appearance.

(3) Since the main metal is vertically long, it can be attached to narrow horizontal members, making it suitable for door frames, etc.
