(Example) This invention will be described in detail below based on an example shown in the drawings.

FIG. 1 is an overall perspective view showing an embodiment of the pin-type article fastening board according to this invention, and FIGS.
The figure is an enlarged cross-sectional view showing the details of the article fastening structure, and the directions will be described below in the illustrated state.

In the figure, 1 is a board main body, and 2 is a board subbody, both of which are made of plastic or metal.

This board body 1 is formed into a shallow box shape by bending the four sides of a rectangular flat plate, and the board surface is provided with penetrating holes 1a for holding the tops of a large number of tack fittings 3 arranged vertically and horizontally. One board subbody 2 is attached to the back side of the board main body 1, and has a number of recessed tack metal fitting storage areas 2a corresponding to the tack metal fitting holding holes 1a. , the tack metal fitting 3 is held by the tack metal fitting holding hole 1a.

This tack fitting 3 has a structure shown in FIGS. 2 and 3 similar to that of a tie tack, and the fitting main body 4 is a hollow body having a flange 4a for positioning within the tack fitting storage part 2a. Hollow part 4b
Forms a tapered inner surface 4c at the upper end, has a pin insertion hole 4d leading from the center of the tapered inner surface 4c to the upper end, further has an opening 4e at the lower end, and projects downward from the hollow section 4b through the opening 4e. A vertically movable pin fixing body 5 is always biased upwardly by a biasing spring 6 and incorporated therein. This pin fixing body 5 has a pin through hole 5a passing through the shaft center.
is provided corresponding to the pin insertion hole 4d of the metal fitting main body 4, and a plurality of (usually three) steel balls 7 are arranged in the circumferential direction at the upper end.
The steel ball 7 is held movably in the diametrical direction of the pin fixing body 5, and since the pin fixing body 5 is biased upward by the biasing spring 6, the outer peripheral surface of the steel ball 7 is pressed against the tapered inner surface 4c. The pin fixing member 5 is always biased toward the center of the pin fixing body 5 along the tapered inner surface 4c, and normally protrudes into the pin passage hole 5a.

A spring seat 5b is fixed to the lower end of the pin fixing body 5 that protrudes from the metal fitting body 4, and the spring seat 5b is connected between the spring seat 5b and the lower end of the metal fitting body 4 in an approximately vertical cross-sectional shape. A step portion 2 is formed at both ends of the lock release spring 8, which is a lock release means made of a bent leaf spring, at the open end of the tack fitting storage portion 2a of the retaining plate sub-body 2.
b, and near both ends of the lock release spring 8 are upwardly curved protruding release actuation parts 8a, 8a, and these release actuation parts 8a, 8a are
Near the tack metal fitting holding hole 2a of the board body 1,
It is arranged so that it can be pressed with a fingertip from the surface side of the board main body 1, facing the two lock release windows 9, 9 provided symmetrically with respect to the tack holding hole 2a.

Reference numeral 10 is made of a flexible plastic sheet or cloth, which is attached to the surface of the board main body 1 to cover the lock release window 9, and a pin insertion hole 4 located at the center of the tack fitting holding hole 1a.
A position display hole 10a or a position display mark in a conspicuous color (especially in the case of a cross) at the position corresponding to d.
is provided.

A large number of tack fittings 3 constructed in this manner are interposed and mounted together with lock release springs 8 between the board main body 1 and the board sub-body 2.

11 is a locking pin, with three circumferential grooves 1 on the pin shaft.
1a, the tip is not sharp but tapers rounded, forming a slightly long plastic head 11b that is easy to pick up.

When this fixing pin 11 is inserted into the tack metal fitting 3 through the position display hole 10a, it is inserted through the pin insertion hole 4d of the metal fitting body 4 into the pin through hole 5a of the pin fixing body 5, and is overhanged into this pin through hole 5a. By pushing the steel ball 7 outward, the steel ball 7 is moved along the tapered inner surface 4c,
The pin is lowered together with the fixed body 5 against the biasing spring 6.

The fixing pin 11 is further pushed in, and the circumferential groove 1
When 1a reaches the position of the steel ball 7, the second
As shown in the figure, the steel ball 7 is pushed in the axial direction and fits into the circumferential groove 11a. Then, even if you try to pull out the retaining pin 11 by holding the head 11b, the steel ball 7 will be lifted.
Due to the action of the tapered inner surface 4c, the circumferential groove 11a becomes more and more
By tightening it, the locking pin 11 was prevented from coming off, and according to experiments, it withstood a tensile force of 80 kg.

To remove the locking pin 11 locked in this way, press the lock release window 9 from the front side of the board body 1 with your fingertip from above the skin material 10 as shown in FIG. 3, and the skin material 9 will become flexible. Since it is provided with the lock release spring 8, it is recessed and presses the release operating portion 8a of the lock release spring 8. As a result, the center part of the lock release spring 8 is lowered, pushing the spring seat 5b and pulling down the pin fixing body 5, and the steel ball 7 is separated from the tapered inner surface 4c and released into the wide hollow part 4b. When the locking pin 11 is pulled up, the steel ball 7 disengages from the circumferential groove 11a and moves outward, the lock is released, and the locking pin 11 can be pulled out.

This fixing pin 11 is used for fixing paper, cloth, etc. to a board surface in the same way as a conventional drawing board, and since the head 11b is made long, it can be used to hang articles on the head. Can be used for hanging. The head of the fixing pin 11 can be manufactured in various shapes and used in a wide variety of ways. For example, the one shown in Fig. 4 has a thin head so that it does not become an obstacle to other objects. They are generally used to fasten various objects, and the one shown in Fig. 5 has a head formed into a hanger hook 12 and is used to hang items, and the one shown in Fig. 6 is a picture frame. 7 is a shallow box-shaped container 14 with three fixing pins attached to the board surface to attach small items. It stores goods, etc., and is convenient for use in factory assembly lines, etc.

In addition to the example head 11b of the fixing pin 11 illustrated above, various heads can be manufactured depending on the purpose of use.

Although the circumferential groove 11a of the locking pin 11 effectively prevents the locking pin 11 from coming off, it can also be used without the circumferential groove 11a. That is, when an attempt is made to pull out the locking pin 11, the steel ball 7 that is in contact with the outer circumference of the locking pin 11 is pulled out of the locking pin 11 by the tapered inner surface 4c.
The more the steel ball 7 is pressed against the outer periphery of the retaining pin 11 and pulled, the more the steel ball 7 grips the retaining pin 11, and cannot be pulled out unless a very strong force is applied.

Further, although the lock release spring 8 is shown as having release actuation portions 8a, 8a formed near both ends, it is possible to have only one of the release actuation portions 8a, that is,
Even if one of the release operating parts 8a is removed, leaving the central part sandwiched between the lower end of the metal fitting body 4 and the spring seat 5b, the lock can be released without any problem. In this case, the lock release window 9 may only be provided on one side.

(Effects of the invention) According to the pin-type article fastening board according to the invention described above, the surface of the board is smooth without any protrusions that may become an obstacle because the tack metal fittings are incorporated inside the board. It can also be used as a bulletin board. Furthermore, the fixing pin for fixing the article is locked simply by inserting it, and it is safe because the fixed article will not come off and come off normally. In addition, the locking pin can be easily unlocked and removed by simply pressing the board surface with your fingertips, and the locking position can be freely selected by selecting the position where the locking pin is inserted. It has many effects, including the ability to change it.
