Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a solution to the problem that when a ceiling plate fixing nail devised by the applicant is used to secure a ceiling board to a knob, the knob gradually shifts to the nail driving side. This relates to a base plate rotating type ceiling board fixing nail that can prevent such problems.

[Conventional technology]

To install the ceiling board, as shown in Fig. 9, attach a dowel 2 (hereinafter referred to as Nobuchi) to the ceiling on which the ceiling board is to be installed, in a direction perpendicular to the length direction of the ceiling board.
) are arranged parallel to each other at appropriate intervals on the surrounding frame, and the upper end of a hanging tree of an appropriate length that suspends and supports the ceiling board 9 is fixed to this knob 2 with nails. Similarly, the lower end of the top plate 9 is fixed to the anchoring beams 4 (hereinafter referred to as vertical lines 4) fixed to both edges of the ceiling plate 9 with nails, and the ceiling plate 9 is raised to a predetermined height. It was hanging there.

This method involves separately attaching the upper end of the hanging tree to the knob 2 with a nail bolt, and then attaching the lower end of the hanging tree to the vertical plate 4 of the ceiling board 9 with a nail hammer'.
Moreover, it was very troublesome as it had to be done in different directions and heights.

For this reason, the present applicant was able to directly fix the ceiling board 9 to the knob 2 with a single nail without using a hanging tree. No. 1289639 (Jikko No. 53-42973) was devised and released under the name ``Shikime Kugi'', which received favorable reviews from carpenters all over the country as being very convenient and allowing for easy and efficient fixing of ceiling boards. They have become popular throughout the country and have become a huge hit, with these nails being used so often that it is impossible to install ceiling boards without them.

As shown in FIG.
An upper nail 3 to be driven into the knob 2 is provided to protrude substantially horizontally in a direction perpendicular to the board surface, and lower nails 5 to be driven into the vertical board 4 are provided to protrude substantially horizontally in the direction of the board surface at the bottom left and right of the bottom part of the board 1. As shown in Figure 4, first Tatezan 4
Drive the lower nail 5 into Nobuchi 2, then drive the upper nail 3 into Nobuchi 2.
You can complete the ceiling board installation work by simply driving in the ceiling board 9. You can easily and reliably attach the ceiling board 9 to the knob 2 with only one sill nail a, instead of requiring a hanging tree and two nails as in the past. It has become a convenient ceiling board peg that can be fixed to the ceiling.

[The problem that the idea attempts to solve]

A big hit product devised by this applicant, Shikume Kugi a
However, there is only one drawback, and the applicant has been thinking of ways to solve this drawback for 10 years.

To explain this drawback, first, when viewed from the side where the upper nail 3 of the paving nail a is driven into the knob 2, it becomes as shown in Fig. 7.

When viewed from the driving side of the tatezan 4, which is the side surface of Fig. 7, it becomes as shown in Fig. 8.

This FIG. 8 is an ideal drawing after the lower nail 5 and upper nail 3 have been inserted, and in reality, the upper nail 3 protrudes integrally with the board 1 and the board 1 comes into contact with the knob 2. Because of the obstruction, the lower nail 5 cannot be driven into the - line position directly below the driving side surface of the knob 2 as shown in FIG.

That is, it is driven into a position separated from the - line by the width l in FIG.

However, unless the lower nail 5 is driven in at the - line position, a serious drawback will occur.

This point will be explained below.

The ceiling boards 9 arranged in parallel are fixed to the knobs 2 in turn, so once the upper nails 3 are driven into the knobs 2, the board 1 is fixed to the knobs 2, so the lower part protruding downward Nail 5 to ceiling board 9
It cannot be typed into Tatezan 4.

Therefore, be sure to drive the lower nail 5 into the vertical shaft 4,
Then the upper nail 3 must be driven into the knob 2.

Therefore, even if you try to drive the lower nail 5 on the - line of the vertical nail 4, it cannot be helped because the upper nail 3 is in the way, so if you drive it at a distance of l width, the knob 2 will be drawn towards the driving side by l width. It makes sense that even if this l is 1 cm, the Nobuchi that has been pulled back by 1 cm will be pulled back by 1 cm the next time it is driven in, so the Nobuchi that should be built straight will end up curving toward the driving side as shown in Figure 10. occurs.

In order to solve this drawback, the l width must be made smaller, and for that purpose, the upper nail 3 can be shortened, but if the nail is made shorter, the nail's fixing force will be weakened, so the l width should be made smaller. It cannot be made smaller.

The applicant has longed to someday solve the shortcomings of the hit product that he has produced, and has completed the present invention by repeatedly making various efforts and taking the following points into consideration.

◎ Do not shorten the upper nail 3 because you do not want to lose the nail's original holding power.

◎ The upper nail 3 should be integrated with the board 1, and
It must be of the type where the plate surface contacts the Nobuchi driving surface.

◎ In order to allow the board 1 to rotate relative to the lower nails 5, a shaft mounting tube 6 is provided at the bottom of the board 1 in the width direction of the board.

◎ The lower nail 5 is provided in a rotatable and slidable manner to prevent it from coming off with respect to the shaft mounting tube 6 so that it can be used on either the left or right side of the vertical rail 4.

[Means to solve the problem]

The configuration will be described in detail with reference to the accompanying drawings as follows.

An upper nail 3 to be driven into the knob 2 is provided on a board 1 to protrude substantially horizontally in a direction perpendicular to the board surface, and a lower nail 5 to be driven into the vertical plate 4 is provided to protrude substantially horizontally in the direction of the board surface at the bottom of the board 1. In the ceiling plate fixing nail for fixing the vertical plate 4 of the ceiling plate 9, a shaft mounting tube 6 is installed horizontally at the bottom of the base plate 1, and a rod-shaped lower nail 5 is rotatably and slidably mounted on this shaft mounting tube 6. The present invention relates to a base plate rotating type ceiling board fixing nail, which is characterized in that it is attached in a manner that prevents it from coming off.

A patent in which the lower end of the substrate 1 is rolled up to form a shaft mounting tube 6, and a round bar 8 having an arrowhead-shaped sharp portion 7 formed at both ends is fitted into the shaft mounting tube 6 so as to be rotatable and slidable. The present invention relates to a base plate rotating type ceiling board fixing nail as set forth in claim 1.

[Effect]

With this configuration, when driving the lower nail 5 into the vertical rail 4 as shown in FIG. 4, the lower nail 5 can be driven correctly on the negative line by rotating the base plate 1 to a position where it does not get in the way.

When driving the upper nail 3 into the knob 2, rotate the board 1 relative to the lower nail 5 to raise it, place the upper nail 3 on the knob 2, and drive it again until the board surface fully contacts the knob 2. I can do it.

The lower nail 5 is stably held by the shaft mounting cylinder 6, and both the rotation of the substrate 1 and the sliding of the lower nail 5 are performed satisfactorily.

〔Example〕

The substrate 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 upper nails 3 are protruded vertically at appropriate intervals by press punching, but the number is not limited to two, and it is also possible to use one nail, or by press punching. The present invention is not limited to this, but the point is that the upper nail 3 should just protrude substantially horizontally.

In the drawing, the lower part of the base plate 1 is bent into a rolled-up state to form a shaft-mounted cylinder 6, and a lower nail 5 formed by a round bar 8 is inserted into this shaft-mounted cylinder 6, and the large-diameter stepped portion of the sharp portion 7 is formed. 10 shows the case where it is prevented from coming off and can be slid left and right, but the point is that the board 1
Any design may be used as long as the pivot tube 6 is provided in the width direction of the lower part of the base plate 1, and the base plate 1 can be rotated with respect to the lower nail 5 so that the upper part thereof swings back and forth.

〔Effect of the invention〕

In the present invention, as described above, the upper nail projects integrally with the board, but the lower nail is not integral with the board, and since the board rotates with respect to the lower nail, the vertical part of the lower nail When driving into the side, rotate the board to the outside until the upper nail does not hit the knob, that is, to a position where it does not get in the way, and in that state match the lower nail to the side of the knob on the vertical side. Drive the upper nail onto the perpendicular line, and raise the board when driving the upper nail into the knob, so you can always drive the lower nail correctly on the vertical line.
It becomes possible to drive in the line position.

For this reason, as in the conventional method, the knobchi is drawn little by little toward the driving side, and the pulled knobchi is pulled again when the next ceiling plate is fixed, and the knobchi is finally curved as shown in Figure 10. This is a rotating type ceiling board fixing nail that exhibits excellent practicality and reliably prevents this.
