A mode for carrying out the invention is shown below. As can be understood from that shown in FIG. 1, in the mounting structure of the L-shaped rail 2 of the present embodiment, a plurality of L-shaped rails 2 having a mounting surface 21 on which a mounted object is mounted extend in the vertical direction. It is attached so as to pass over the attachment 4 of. The L-shaped rail 2 includes a locking piece 22 that locks into a mounting hole 41 provided in the mounting tool 4, and a hooking piece 51 that is elastically deformable in a direction parallel to the mounting surface 21. After the locking piece 22 is inserted into the mounting hole 41, the hooking piece 51 can be inserted into the mounting hole 41 for fixing. Therefore, the L-shaped rail 2 can be easily fixed to the fixture 4 without tools.

Here, the L-shaped rail 2 of the embodiment will be described. The L-shaped rail 2 includes a metal L-shaped rail main body 20 having a mounting surface 21 on which the mounted object is mounted. As can be understood from FIG. 1, the L-shaped rail main body 20 is mounted so as to pass over a plurality of mounting tools 4 extending in the vertical direction, and at this time, the mounting surface 21 expands in the horizontal direction. It is installed like this.

As can be understood from FIGS. 2 and 3, the L-shaped rail main body 20 includes a vertical surface 23 extending in a direction different from that of the mounting surface 21, and the cross section is substantially L due to the vertical surface 23 and the mounting surface 21. It is configured to be in the shape of a letter. Further, the L-shaped rail main body 20 is provided with a connecting surface 24 extending in a direction different from that of both the mounting surface 21 and the vertical surface 23. The connection surface 24 is provided at both ends of the mounting surface 21. In the embodiment, the connecting surface 24 is formed so as to form a right angle to the mounting surface 21 and the vertical surface 23 by bending the portion following the portion to be the mounting surface 21.

The connection surface 24 of the embodiment includes, at one end, a locking piece 22 that locks into a mounting hole 41 provided in the mounting tool 4. The locking piece 22 is configured in a hook shape so as to project outward from the vertical surface 23, and by inserting it into the mounting hole 41, the L-shaped rail main body 20 is in a state of being hooked on the mounting tool 4. Can be done. The locking piece 22 of the embodiment is provided in a hook shape at one end of the flat connecting surface 24, and the force applied to the locking piece 22 can be dispersed on the connecting surface 24. Therefore, the load on the locking piece 22 can be suppressed.

In the embodiment, two hook-shaped locking pieces 22 are arranged one above the other. In this way, for example, each locking piece 22 can be locked in each of the mounting holes 41 provided in the mounting tool 4 so as to be arranged vertically. That is, since the two locking pieces 22 arranged vertically can be hooked on the two mounting holes 41 arranged vertically, the possibility that the L-shaped rail body 20 falls off from the fixture 4 is further reduced. can.

In the L-shaped rail 2 of the embodiment, the hooking member 50 is attached to the L-shaped rail main body 20. The hooking member 50 is made of resin, and as can be seen from FIGS. 4 and 5, the hooking member 51 is configured so that the elastically deformable hooking piece 51 extends from the hooking member main body 52. The hook piece 51 is located above the locking piece 22, and the elastically deformed state can be visually recognized. The hooking member 50 is formed at each end of the L-shaped rail main body 20, and since the hooking member 50 has a vertically symmetrical shape, one member can also be used.

The hook piece 51 may be inserted into any of the mounting holes 41, but it is preferable to insert the hook piece 51 into the mounting hole 41 into which the locking piece 22 is inserted and fix the hook piece 51. When the locking piece 22 and the hooking piece 51 are inserted into one mounting hole 41, the hooking piece 51 prevents the locking piece 22 from coming off, making it difficult for the L-shaped rail 2 to move. The stop piece 22 can be made difficult to come off from the mounting hole 41.

The hooking member 50 of the embodiment is screw-fixed to the mounting surface 21 of the L-shaped rail main body 20. The hook member 50 is provided with a shaft stop portion 53 extending in the vertical direction, which is separated from the screw stop portion 54 into which a male screw is inserted in the horizontal direction. Further, the shaft stop portion 53 is configured to be screw-fixed in a state of being fitted in a hole provided in the mounting surface 21 of the L-shaped rail main body 20. Therefore, when the male screw is inserted into the screwed portion 54 and the hooking member 50 is screwed and fixed to the L-shaped rail main body 20, the rotation of the hooking member 50 is suppressed, and the hooking member 50 is suppressed at an appropriate position. It becomes easier to fix. In this way, if the hooking member 50 is fixed by using the plurality of shafts, it is possible to prevent the hooking member 50 from being attached in an inappropriate state.

In the embodiment, the shaft stop portion 53 and the screw stop portion 54 are arranged so as to be displaced in the front-rear direction and the left-right direction, and the hook member 50 can be attached in an appropriate direction.

As can be understood from FIG. 6, in the embodiment, the wall is made thin in order to widen the range of movement of the elastically deformable hook piece 51. That is, the tip side of the hook piece 51 is shorter than the base end side in the vertical direction. This is because the hook piece 51 can be moved toward the mounting surface 21 side by providing a gap between the hook piece 51 and the mounting surface 21. In this way, if the hook piece 51 has a tip portion thinner than the base end portion, the hook piece 51 can be easily inserted into the mounting hole 41. The outer side of the hook piece 51 is formed in an uneven shape so that the operator's finger (claw) can easily enter and the hook piece 51 can be easily locked. Further, since the uneven shape is formed, the uneven portion engages with the left and right end portions of the mounting hole 41, and rattling can be less likely to occur.

Since the hooking member 50 of the embodiment may be used upside down, the hooking piece 51 should be accommodated at a position closer to the center than the upper and lower ends of the hooking member main body 52 that supports the hooking piece 51. The hook piece 51 can be bent upward and downward.

The hook piece 51 is provided with a claw portion 55 on the tip end side, and the claw portion 55 is inserted into a mounting hole 41 provided in the fixture 4. In the embodiment, a claw portion 55 having an acute angle with the arm 56 is provided on the tip end side of the arm 56 provided on the hook piece 51. In the embodiment shown in FIG. 1, the hooking member 50 is provided at the front and rear end portions of the L-shaped rail main body 20, and the tip of the claw portion 55 is a locking piece in a state where the hooking piece 51 is not elastically deformed. The claw portion 55 of the hook member 50 arranged at the front end portion (rear end portion) of the L-shaped rail main body 20 is closer to the center of the L-shaped rail 2 than the 22 (in the case of the example shown in FIG. 1, the L-shaped rail body 20 is L-shaped. It is configured to be located on the hooking member 50 side (side of the hook member 50) arranged at the rear end portion (front end portion) of the rail body 20. Further, the hook piece 51 is elastically deformed so that the tip of the claw portion 55 faces the mounting hole 41. In the hooking member 50, when the claw portion 55 is locked to the mounting hole 41, the claw portion 55 urges the end portion of the mounting hole 41.

In the embodiment, as will be described later, the hooking piece 51 is elastically deformed by tilting the L-shaped rail 2 in a state where the locking piece 22 is inserted into the mounting hole 41, and the hooking piece 51 is formed. The tip of the claw portion 55 of the hook piece 51 is moved closer to the center of the mounting hole 41 than in the case where it is not elastically deformed, and the front and rear positions of the tip of the claw portion 55 of the hook member 50 are positioned at the front and rear positions of the end of the locking piece 22. The hook piece 51 can be inserted into the back of the mounting hole 41 in the same manner as the front-rear position of the portion. Further, since it has the above-mentioned configuration, it can be firmly fixed by the action of elastic force. The claw portion 55 of the embodiment is attached because it is configured to protrude toward the center of the L-shaped rail 2 from the tip of the locking piece 22 in a state where the hooking piece 51 is not elastically deformed. In the state of being locked in the hole 41, it is locked so as to urge the left and right ends of the mounting hole 41 by the action of elastic force.

By the way, since the locking piece 22 is inserted into the mounting hole 41 before the hooking piece 51, when the hooking piece 51 is to be elastically deformed, a force is applied to the hooking piece 51 in a state where the position is fixed to some extent. be able to. Therefore, it is relatively easy to put the hook piece 51 into the mounting hole 41. In the embodiment, after the locking piece 22 is inserted into the mounting hole 41, the hooking piece 51 is pressed against the mounting tool 4 to elastically deform the hooking piece 51, so that the locking piece 22 is locked in the back of the mounting hole 41. The piece 22 can be inserted. As can be understood from FIG. 6, the locking piece 22 is configured to protrude laterally from the hooking piece 51, and the locking piece 22 is larger than the hooking piece 51. It is easy to insert it into the mounting hole 41 first.

In order to make it easier to insert the claw portion 55 into the mounting hole 41, the claw portion 55 of the embodiment is configured so that the tip is tapered. The upper surface of the tip of the claw portion 55 of the embodiment is configured to be inclined upward from the tip side toward the base end side. Further, the hook piece 51 is provided so as to have a gap with the mounting surface 21 of the L-shaped rail main body.

Therefore, as can be understood from FIGS. 7 and 8, the locking piece 22 is inserted into the mounting hole 41, and the claw portion 55 is pushed in from the state where the mounting surface 21 is slanted. When the inclination of the rail 2 is changed, the claw portion 55 is elastically deformed downward, and the claw portion 55 is inserted into the back of the mounting hole 41. When the L-shaped rail 2 is rotated until the mounting surface 21 becomes substantially horizontal, the claw portion 55 is sufficiently caught by the mounting tool 4, and the L-shaped rail 2 is less likely to fall off from the mounting tool 4.

Since the hook member 50 of the embodiment can be used in the same manner even if it is turned upside down, the upper surface side of the tip of the claw portion 55 is inclined downward toward the end side, and the lower surface side is toward the end side. It is tilted upward toward it. These inclinations serve as a guide portion 57 that assists the hook piece 51 from being inserted into the mounting hole 41.

As described above, assuming that the guide portion 57 for assisting the hooking piece 51 to be inserted into the mounting hole 41 is provided on the upper surface and the lower surface of the hooking piece 51, the tip of the locking piece 22 is inserted into the mounting hole 41. It will be easier. Further, a guide portion 57 tilted downward toward the end side of the claw portion 55 is provided on the upper surface side of the tip of the claw portion 55, and the guide portion 57 tilted upward toward the end portion side of the claw portion 55 is clawed. If the configuration is provided on the lower surface side of the tip of the portion 55, the guide portion 57 does not become an obstacle even when the L-shaped rails 2 are stacked in the vertical direction, which is preferable.

By the way, usually, a plurality of L-shaped rails 2 are attached to the cabinet. Typically, as can be seen from FIG. 9, the mounting surfaces 21 of the L-shaped rails 2 are arranged in parallel so as to have the same height. In this way, as can be seen from FIGS. 10 and 11, the shelf board 8 and the like can be supported by the L-shaped rail 2.

In this way, the L-shaped rail 2 can be used to support the shelf board 8, but when the shelf board 8 is arranged so as to be supported by the four vertically extending attachments 4, the side far from the operator This part is a little difficult to grasp, and there is a risk that positioning will take time. In order to cope with this problem, the hooking member 50 of the embodiment includes a surface of the hooking piece 51 opposite to the surface on which the claw portion 55 protrudes, and a hooking piece 51 from the hooking member main body 52. An inclined surface 59 is provided so as to cover both surfaces on the side opposite to the extending direction. Therefore, when the hooking member 50 is attached to the L-shaped rail main body 20, the inclined surface 59 is located at the position closest to the central portion of the L-shaped rail main body 20 among the four corners of the hooking member 50 in a plan view. become. The inclined surface 59 of the hooking member 50 arranged at such a position can exert a function of correcting the deviation of the shelf board 8 in the left-right direction when the shelf board 8 is slid to the rear side and attached to the shelf. It helps the positioning of the plate 8.

By the way, as can be understood from FIG. 3, in the embodiment, the fixing hole 26 is provided on the vertical surface 23 of the L-shaped rail 2. The fixing hole 26 is provided so that the L-shaped rail 2 can be screw-fixed to the fixture 4 or the like when the strength is uncertain, and may be used as needed.

Further, on the mounting surface 21 of the L-shaped rail 2 of the embodiment, the shelf board fixing used so as to engage with the shelf board fixing portion 81 when the shelf board 8 is fixed to the L-shaped rail 2 is fixed to both ends thereof. It has a hole 28. Further, a plurality of binding holes 27 are provided along the longitudinal direction of the L-shaped rail 2. The binding hole 27 can be used together with other holes to hold or bind the cable. For example, a cable may be routed through a binding band 27 provided in each of the paired L-shaped rails 2, or a binding hole 27 provided in the L-shaped rail 2 and a shelf board 8 may be provided. Cables can be routed by passing a cable tie through the holes.

Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be in various modes. For example, the entire L-shaped rail may be made of the same member or the same material.

In addition, there is only one type of hooking member in the embodiment, and the top and bottom are symmetrical so that they can be attached to both the front end and the rear end of the L-shaped rail body, but the structure does not have to be limited to the top and bottom. ..
