As a result, the first locking claw portion 11 is easily inserted into the slit 51, and after being inserted into the slit 51, the first locking claw portion 11 is locked to the inner corner 53a above the slit 51. The vertical length of the first locking claw portion 11 is about 17 mm.

In the locking main body portion 10, the second locking claw portion 12 extends downward from the end portion of the locking claw portion 1 on the support member side of the horizontal support portion 2. Further, the vertical length (L ₂ ) of the second locking claw portion is smaller than the vertical length (L ₁ ) of the first locking claw portion. As a result, the locking claw portion 1 can be easily inserted into the slit 51. Further, the side surface 15 of the second locking claw portion 12 on the horizontal support portion 2 side or the internal angle 151 of the second locking claw portion 12 and the horizontal support portion 2 is the inner wall surface 52b of the support member 5 on which the slit 51 is formed. Alternatively, it comes into contact with the inner angle 53b below the slit 51. The side surface 15 of the second locking claw portion 12 is linear in a side view. In a state where the locking body 10 is fixed to the support member 5, an extension of the upper side 15 of the second locking claw portion 12 (upper X ₁ -X ₁ in Fig. 2), the first engagement The inclined surface 111 of the claw portion 11 will be located. As a result, the inclined surface 111 of the first locking claw portion 11 abuts on the inner angle 53 above the slit 51, and the second locking claw portion 12 abuts on the inner wall surface 52b of the steel material 5 below the slit 51. In a state where the locking body portion 10 is fixed to the support member 5, the side surface 15 of the second locking claw portion 12 is formed by the first locking claw portion 11 and the horizontal support portion 2 in a side view. It is located on the anti-horizontal support side from the internal angle 141. The vertical length (L ₁ ) and the vertical length (L ₂ ) refer to the length in the vertical direction when the horizontal support portion 2 is in a horizontal state.

In the locking body portion 10, the horizontal support portion 2 is a plate-like body to which the mounting member 3 extending from the locking claw portion 1 in the direction of the anti-support member is mounted. The length of the horizontal support portion 2 in the front-rear direction is the length to which the mounting member 3 is mounted (for example, 15 to 17 mm), and the height in the vertical direction is a dimension sufficient to support the mounting member 3 such as a cylindrical dowel. Yes, for example 5-6 mm. Further, a male screw 21 is attached to the horizontal support portion 2. The male screw 21 is screwed into the female screw 32 formed on the mounting member 3.

In the present invention, the locking fixture 20 has a locking main body 10 and a mounting member 3 as shown in FIG. Examples of the mounting member 3 include the columnar dowel shown in FIG. The columnar dowel 4 is provided with a female screw 32 that is screwed with a male screw 21 attached to the horizontal support portion 2 of the locking fixture 20.

In this way, the cylindrical dowel 3 is screwed into the horizontal support portion 2 of the locking main body portion 10 to obtain the locking fixture 20, and the locking fixture 20 is attached to the support member 5 having the slit 51.

In the present invention, examples of the support member 5 include a channel (groove type) steel material having a U-shaped cross section, an H-shaped cross section, or an L-shaped cross section having a slit 5, and a pipe steel material. A large number of slits 5 are formed in the vertical direction of such a steel material at a predetermined pitch. For example, as shown in FIG. 8, through holes having a rectangular cross-sectional shape having a vertical dimension L and a width dimension w are listed. Be done. Such a support member 5 is fixed to the wall surface with screws or the like, for example. As shown in FIGS. 5 to 8, in the steel material 5 in which the slit 51 is formed, the inner angle 53a above the slit 51, the inner angle 53b below, and the inner wall surface 52b of the steel material below the slit 51 are the locking claws 1. It becomes a locking part.

Next, a method of attaching the columnar dowel 3 using the locking fixture 20 will be described with reference to FIGS. 5 to 7. First, the locking fixture 20 is assembled. The locking fixture 20 is obtained by attaching a cylindrical dowel 3 to the horizontal support portion 2 of the locking main body portion 10 by screwing. At this time, the cylindrical dowel 3 is not screwed to the end in the horizontal support portion 2 of the locking main body portion 10, but is stopped in the middle.

Next, as shown in FIG. 5, the locking fixture 20 is placed in the slit 51 with the first locking claw portion 11 of the locking claw portion 1 facing upward from a posture in which the tip of the locking claw portion 1 faces diagonally upward. insert. Next, as shown in FIG. 6, the locking claw portion 1 is rotated in the slit 51 to make the first locking claw portion 11 stand up in the slit 51, and further, at an internal angle 53b below the slit 51. Positioning is performed by hand so that the horizontal support portion 2 and the internal angle 151 of the second locking claw portion 12 are brought into contact with each other, and the inclined surface 111 of the first locking claw portion 11 is in contact with the internal angle 53a above the slit 51. And attach it. For this positioning, it is only necessary to bring the horizontal support portion 2 and the inner angle 151 of the second locking claw portion 12 into contact with the inner angle 53b below the slit 51, and the position is uniquely determined. Therefore, unlike the conventional locking fixing member (locking fixture), positioning is not mistaken. Further, the inner corner 53a of the slit 51 abuts on any surface as long as it is an inclined surface 111, and can be used for slits having various vertical dimensions, and the range of use of the locking fixture 20 of the present invention. Spreads.

Next, the columnar dowel 3 is screwed in until it almost hits the surface of the steel material. At this stage, there is a possibility that the locking fixture 20 is displaced upward with respect to the steel material 5, so the locking fixture 20 is pushed down again, and the horizontal support portion is formed at the inner angle 53b below the slit 51. 2 and the inner angle 151 of the second locking claw portion 12 are surely brought into contact with each other. Next, by further screwing the columnar dowel 3, the end face of the columnar dowel 3 is strongly brought into contact with the surface of the steel material 5. As a result, the steel material 5 is sandwiched between the locking claw portion 1 and the columnar dowel 3, and the locking fixture 20 can be strongly fixed to the slit 51. That is, since the inclined surface 111 of the first locking claw portion 11 abuts on the inner corner 53a of the slit 51 by line contact, two component forces of the horizontal direction and the vertical direction (downward direction) are generated as the tightening force. , Stronger tightening is possible compared to the tightening force due to face-to-face contact.

In the present invention, the locking fixture 20 is attached to slits 51 of the same height level of the steel material at the four corners, and the shelf board member is placed on the columnar dowels 3 at the four corners to form a display surface. The locking fixture 20 is not limited to the four corners, and may be attached to a pair of left and right steel materials at the rear or front, and may be supported at the front or rear by other supporting means. Further, if necessary, a resin sleeve or the like may be attached to the cylindrical dowel 3, and a shelf plate member such as a glass plate may be placed on the sleeve.

The present invention is not limited to the above-described embodiment, and various modifications can be taken. For example, in the locking claw portion 1, the lengths of the first locking claw portion 11 and the second locking claw portion 12 in the vertical direction may be the same. Further, as shown in FIG. 2, the inclined surface 111 of the first locking claw portion 11 is not limited to an arc shape from the tip to the connection point of the horizontal support portion 2, and the first locking claw portion 11 has an inclined surface 111. Includes some that are sloped. Incidentally, the inclined surface 111 is at least from the tip 13 of the first locking claw portion 11 downwardly, may be formed in a portion of the (L _1/2) or more in length, for example, the first locking claw portion 11 generally from the tip 13 of the (3L _1/4) length of the portion of is formed in an inclined shape, toward the horizontal support 2 connection point of the first locking claw portion 11 upward (L _1/4) The portion may be an inclined surface whose inclination is less than that of the inclined surface 111, or may be a straight (vertical) surface. Further, in the present invention, the inclined surface 111 is not limited to the inclined surface (arc surface) slightly convex toward the horizontal support portion side, and may be an inclined surface having a linear inclination in the side view. Further, the locking fixture 20 may be attached upside down with respect to the slit 51 of the steel material 5.

According to the present invention, when the locking fixture is attached to the support member, the upper and lower fixing positions are uniquely determined, and no deviation occurs during screwing. Therefore, no mounting error occurs. Further, since the inclined surface of the first locking claw portion abuts on the inner corner of the slit by line contact, strong fixing can be realized. Further, the inner corners of the slit may come into contact with any surface as long as it is an inclined surface, and can be used for slits having various vertically long dimensions.
