Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vertical plate rotating type sill nail that prevents the dowel from gradually shifting when the sill nail is used.

[Conventional technology]

To install the ceiling board, as shown in Figure 3, parallel beams called "nobuchi" are installed above the position where the ceiling board is installed perpendicular to the length direction of the ceiling board. Fix the upper end of a hanging tree of an appropriate length to support the ceiling board by nailing it to the ceiling plate (often constructed in a grid frame for reinforcement), and then attach the lower end of this hanging tree to the top plate support beam of the ceiling board in the same way. The ceiling panels were hung at a specified height by fixing them with nails.

In this method, the act of fixing the upper end of the hanging tree to the nobu with nails and the act of first fixing the lower end of the hanging tree to the top plate support beam of the ceiling board with nails are performed separately, and in addition, the nailing is done in the direction in which the hanging tree is driven in. This was extremely troublesome as it had to be done at different heights.

For this reason, the applicant has registered Utility Model No. 12896, which allows ceiling panels to be fixed directly to the tabs with a single nail, without using hanging trees.
38 (Utility Model No. 53-42972) and Utility Model Registration No. 1289639 (Utility Model No. 1289639).

This shikime nail was so revolutionary that it became popular throughout the country and was called the Ishikawa-style shikime nail, and is now so widely used that ceiling boards cannot be installed without it.

As shown in Fig. 4, this shikime nail has an upper needle that is driven into a vertical board in a direction that projects approximately horizontally in a direction perpendicular to the board surface.
A lower needle that is driven into the top support bar is installed at the bottom of the vertical board, protruding almost horizontally in the direction of the board surface.Simply drive the lower needle into the top support bar first, and then drive the top needle into the nook. The ceiling panel installation work has been completed.

This is a convenient cross-metal nail that allows you to easily attach ceiling panels.

[Problem that the invention attempts to solve]

When driving this nail into the side of the ceiling plate support beam,
If you don't drive the lower needle onto the perpendicular line that matches the side of the nobuchi, you will not be able to fasten it in the correct position.

However, since the upper needle that is driven into the side of the nobuchi protrudes opposite the nobuchi, this gets in the way and causes the vertical board to be slanted, creating an optical illusion that prevents the needle from being driven correctly on the perpendicular line. It's difficult, and you have to hit it a little closer to the perpendicular line.

For example, if there are 10 ceiling boards, there will be a total of 20 ceiling support bars on the left and right, and if all 20 are driven slightly in front of you, the error in each one will be extremely small. It has been found that when all the driving is done little by little, the retracting force causes the upper tab to gradually shift toward the front, and there is a drawback that it deviates from the predetermined position by several CZ at the end.

[Means for solving problems]

The present invention solves this drawback, and its structure will be detailed as follows with reference to the accompanying drawings.

An upper needle 3, which is driven into the slot 2 of the vertical board 1, is provided protruding approximately horizontally in a direction perpendicular to the board surface, and a lower needle 5, which is driven into the top plate support beam 4, is provided at the bottom of the vertical board 1, approximately horizontally in the direction of the board surface. This is characterized in that the lower part of the vertical plate 1 is rotatably attached to the lower needle 5 in the paving nail a protruding from the lower needle 5, and the vertical plate 1 is rotatably provided to the lower needle 5.

In addition, a rod 8 is formed in which a winding part 6 is formed at the lower end of the vertical plate l, and an arrowhead-shaped sharp part 7 is formed at both ends of the winding part 6.
It is inserted and attached freely so that it can rotate freely.

[For production]

When driving the lower needle 5 onto the perpendicular line E on the side of the top plate support beam 4 of the ceiling plate 9, which is perpendicular to this, rotate the vertical plate 1 outward so as not to get in the way. After driving the lower needle 5, rotate the vertical plate 1 to raise it, and then drive the upper needle 3 into the notch 2.

〔Example〕

Although the vertical plate 1 in the drawings is a flat plate, it is not limited to a flat plate, and may have any shape as long as it is a bar-shaped rod.

The vertical plate 1 may be made of any material such as steel plate or hard plastic.

The upper nail 3 in the drawing shows a case in which two nails 3 are protruded horizontally at an appropriate interval by press punching.
The nail 3 is not limited to a book, and may be one, and the nail 3 is not limited to press punching.In short, it is sufficient that the upper nail 3 protrudes substantially horizontally.

In the drawing, the lower part of the vertical plate 1 is bent into a rolled-up state, a bar-shaped lower nail 5 is inserted into the rolled-up part 6, and the large-diameter step part 10 of the sharp part 7 prevents it from being pulled out, allowing it to slide left and right. This example shows a case in which the vertical plate 1 can be attached to the lower nail 5, but it may also be attached so that it only rotates and does not slide.
As long as it has a structure in which the upper part rotates in a swinging state, it may be in any pivoted state or loose state.

・ [Effects of the Invention] As described above, in the present invention, since the vertical plate rotates with respect to the lower nail, the upper nail gets in the way and the vertical plate remains slanted when the lower nail is rotated. There is no need to drive nails,
Driving the lower nail is done without regard to the vertical plate, that is, by rotating the vertical plate to a position where it does not get in the way, and in that state, the lower nail can be pierced and driven at the extreme end, so that it matches the side of the nobuki correctly. It becomes possible to drive the nail onto the perpendicular line E, and the upper nail can be driven into the notch by raising the vertical board.

For this reason, it is a vertical plate rotating shime nail that exhibits excellent practicality by gradually drawing the nobuchi towards you little by little and reliably preventing the conventional drawback of shifting by several hundred points at the end. becomes.
