However, the conventional article locking member cannot support a plurality of types of support walls having different specifications by one article locking member. Therefore, when the target article is locked to a support wall having different specifications, another article locking member suitable for the specifications of the support wall must be prepared. Therefore, when the above-mentioned conventional article locking member is adopted, it is necessary to prepare a plurality of article locking members according to the specifications of the support wall (holding member) in advance, so that the preparation cost rises or the storage is performed. It causes inconveniences such as time and effort.

Therefore, the present invention is intended to provide an article locking member that can be used in a plurality of types of support walls having different specifications of the support structure.

The article locking member according to the present invention adopts the following configuration in order to solve the above problems.
That is, the article locking member according to the present invention is an article locking member that holds an object article and is locked to the support wall of a support structure having a support wall that stands upright above the support wall. A base wall having an facing surface facing the front surface, an article engaging portion provided on the base wall and capable of holding the target article, and an article engaging portion provided on the base wall so as to project from the facing surface of the base wall in the vertical direction. Each of the locking hooks comprises a plurality of locking hooks, one of which is selectively locked to the supporting wall, each of which is a rear extending piece extending rearward from the facing surface and the rear extending piece. It has a downward extending piece extending downward from the rear portion of the piece, and the plurality of the locking hooks have a distance between the facing surface and the downward extending piece as the locking hook is arranged upward. It is a feature that the extension length of the downward extension piece is formed longer as the locking hook is arranged wider and lower.

With the above configuration, when locking the article locking member to the support wall of the support structure, one of the locking hooks suitable for the vertical extension length of the support wall, the thickness in the front-rear direction, etc. is selected. , Lock the selected locking hook to the support wall. In the article locking member having the above configuration, the locking hook arranged on the upper side of the base wall has a wider separation width between the facing surface and the lower extending piece, and the extending length of the lower extending piece is shorter. Since it is formed, even if another locking hook exists below the upper locking hook to be locked to the support wall, interference with the other locking hook is avoided and the upper locking is avoided. The hook can be securely locked to the support wall.
Further, in the article locking member according to the present invention, the extending length of the downward extending piece is formed longer as the locking hook on the lower side of the base wall is formed, so that the article locking member has the longest engagement when locked with the support wall. There are no other locking hooks below the bottommost locking hook that requires a stroke. Therefore, it is possible to easily lock and release the locking hook with respect to the support wall having a long extension length in the vertical direction.
Further, in the case of the article locking member according to the present invention, the locking hook on the upper side having a short extending length of the downward extending piece is locked to the thick support wall in the front-rear direction, and the locking hook on the upper side is locked in the front-rear direction. A locking hook on the lower side having a long extension length of the downward extension piece can be locked to the support wall having a thin thickness. If the input load is constant, the stress due to the load acting on the support wall from the article locking member is the thickness of the support wall in the front-rear direction and the vertical contact width of the locking hook with respect to the support wall (downward extension piece). It is almost determined by the product with the extension length). Therefore, according to the above configuration, even when the article locking member is locked to the thin support wall in the front-rear direction, the increase in stress acting on the support wall is suppressed, and the support wall is deformed or warped. Can be prevented.

At least in the locking hook on the lowermost end side, the separation width between the lower edge portion of the lower extension piece and the facing surface is narrower than the separation width between the upper edge portion of the lower extension piece and the facing surface. It may be formed.
In this case, the locking hook arranged on the lower side of the base wall can be locked to the support wall having a thinner thickness in the front-rear direction, but at least the locking hook on the lowermost end side faces the base wall. Since the separation width between the surface and the lower edge portion of the downward extending piece is narrowed, it is possible to advantageously suppress the collapse of the article locking member. Further, in the case of this structure, at least the locking hook on the lowermost end side has a separation width between the upper edge portion of the lower extension piece and the facing surface, which is larger than the separation width between the lower edge portion of the lower extension piece and the facing surface. Is also wide, so that the work of attaching / detaching the article locking member to the support wall can be easily performed.

Any of the locking hooks located below the topmost locking hook projects rearwardly from the rear surface of the topmost locking hook so that the topmost locking hook supports the support. A support surface that can come into contact with the front surface of the support structure when locked to a wall may be provided.
In this case, when the uppermost locking hook is locked to the corresponding support wall, the support surface provided on the other lower locking hook can come into contact with the front surface of the support structure. Therefore, when a load in the tilting direction acts on the article locking member, the support surface comes into contact with the support structure on the lower side of the locking hook locked to the support wall. As a result, the collapse of the article locking member is surely regulated.

The support surface may be provided at the end of the locking hook in the extension direction of the rear extension piece.
In this case, the reaction force when the support surface comes into contact with the support structure can be received by the rear extending piece extending in the front-rear direction. Therefore, when this structure is adopted, the collapse of the article locking member can be more reliably regulated.

According to the present invention, a plurality of locking hooks are provided so as to project from the facing surfaces of the base wall in the vertical direction, and any of the locking hooks suitable for the support wall can be selectively locked. Therefore, one article locking member can be applied to a plurality of types of support walls having different specifications.
Further, according to the present invention, the locking hook arranged above has a wider separation width between the facing surface and the downward extending piece, and the locking hook arranged below has the extending length of the downward extending piece. Since the length is long, even if another locking hook exists below the locking hook on the upper side to be locked to the support wall, interference with the other locking hook is avoided and the upper side is avoided. Locking hook can be securely locked to the support wall. Furthermore, since there is no other locking hook at least below the lowermost locking hook, it is easy to lock and release the lowermost locking hook and the support wall, which require a long engagement stroke. It can be carried out.
Further, according to the present invention, the locking hook arranged above has a wider separation width between the facing surface and the downward extending piece, and the locking hook arranged below has the extending length of the downward extending piece. Since the length is long, even when the article locking member is locked to the thin support wall in the front-rear direction, the increase in stress acting on the support wall is suppressed and the deformation and runout of the support wall are prevented. can do.

The lower extending piece 14Bb extends downward from the protruding portion 16 and the lower edge portion bulges (bends) forward to the stepped portion. The distance between the bulging portion 17 and the facing surface 15 of the base wall 12 is narrower than the region above the bulging portion 17 of the downward extending piece 14Bb. That is, in the case of the article locking member 10 of the present embodiment, the lower locking hook 14B has a downward extending piece 14Bb having a separation width Wb-1 between the lower edge portion of the lower extending piece 14Bb and the facing surface 15. It is formed to be narrower than the separation width Wb between the upper edge portion and the facing surface 15. Further, at the lower end portion of the downward extending piece 14Bb, a bent portion 18 bent at a substantially right angle is provided on the rear side.

In the article locking member 10 of the present embodiment, any of the upper and lower locking hooks 14A and 14B of the base wall 12 can be supported by support walls having different specifications of the support structure. The lower locking hook 14B can be locked to, for example, the support wall 11 having a long extension length in the vertical direction of the beam member 4 of the board holding base 1 shown in FIG. In the board holding table 1 of the present embodiment, the article locking member 10 can be locked to any of a plurality of beam members 4, and the board member 5 can be supported by the beam member 4 selected in that state. Further, the article locking member 10 can be locked at an arbitrary position in the extending direction of the beam member 4.

FIG. 5 shows the state of the article locking member 10 when the article locking member 10 is locked to the holding component 20 provided on the supporting structure 40 different from the board holding table 1. It is a figure which showed the wall 21 and the holding part 20 in the cross section.
The locking hook 14A on the upper side can be locked to, for example, the support wall 11A having a short extension length in the vertical direction of the holding component 20 shown in FIG.

The holding component 20 shown in FIG. 5 includes a base portion 22 fixed by a screw 41 to a wall 21 standing above the support structure 40, and a plurality of locking parts protruding forward from the base portion 22 to hold the functional component 23. It has claws 24a and 24b, and a support wall 11A that rises diagonally forward and upward from the lower end of the base portion 22. The support wall 11A of the holding component 20 is formed to have a shorter extension length in the vertical direction and a slightly thicker thickness in the front-rear direction than the support wall 11 of the board holding base 1 shown in FIG. Further, a support protrusion 11Aa projecting upward is formed at the base of the support wall 11A. When the locking hook 14A on the upper side of the article locking member 10 is locked to the support wall 11A, the lower end of the downward extending piece 14Ab of the locking hook 14A can come into contact with the upper surface of the support protrusion 11Aa. ing.

Actually, when the article locking member 10 is attached to the support structure 40 shown in FIG. 5, the upper locking hook 14A is attached to the support wall 11A of the holding component 20 previously attached to the wall 21 of the support structure 40. Hook from above to lock. At this time, the tip side of the support wall 11A is inserted inside the upper locking hook 14A in a posture in which the lower end side of the article locking member 10 is inclined so as to be separated from the wall 21, and the article locking member 10 is inserted from that state. The locking hook 14A is hooked on the support wall 11A by returning the tilted posture of. As a result, the locking hook 14A is inserted into the concave groove in which the downward extending piece 14Ab opens upward between the support wall 11A and the base portion 22, and the lower end of the downward extending piece 14Ab is placed on the upper surface of the supporting protrusion 11Aa. Contact. At this time, the upper end portion of the support wall 11A abuts on the lower surface of the rear extending piece 14Aa.

Further, at this time, in the locking hook 14B on the lower side of the article locking member 10, the support surface 16a (protruding portion 16) at the rear end of the rear extending piece 14Ba abuts on the front surface of the wall 21 of the support structure 40. Or close. As a result, when a large load in the downward downward direction is input to the article engaging portion 13 of the article locking member 10, the support surface 16a is below the locking hook 14A on the upper side, and the wall 21 of the support structure 40 is formed. In contact with the article locking member 10, the collapse of the article locking member 10 is restricted. In particular, when a heavy target article such as a board material 5 is held by the article engaging portion 13 of the article locking member 10, the article locking member 10 is likely to fall down, but the lower locking hook 14B When the support surface 16a comes into contact with the wall 21, it is possible to prevent the article locking member 10 from collapsing.
In the present embodiment, since the bent portion 18 is provided at the lower end of the downward extending piece 14Bb of the lower locking hook 14B so as to project rearward, the rear end surface of the bent portion 18 is also supported. It can come into contact with the wall 21 of the body 40. Therefore, when a large load in the tilting direction is input to the article locking member 10, the support surface 16a at the rear end of the rear extending piece 14Ba and the rear end portion of the bent portion 18 come into contact with the wall 21, thereby engaging the article. It is possible to more reliably regulate the collapse of the stop member 10.

Further, when the article locking member 10 is attached to the beam member 4 of the board holding base 1 shown in FIG. 4, the lower locking hook 14B is hooked on the support wall 11 of the channel member 4B from above to lock the article locking member 10. At this time, the article locking member 10 is displaced downward so that the upper portion of the support wall 11 is inserted into the gap between the base wall 12 and the downward extending piece 14Bb of the locking hook 14B. As a result, the upper end of the support wall 11 is deeply inserted into the gap between the base wall 12 and the downward extension piece 14Bb, and the upper end surface of the support wall 11 comes into contact with the lower surface of the rear extension piece 14Ba of the locking hook 14B. At this time, the bent portion 18 at the lower end of the locking hook 14B comes into contact with the upper surface of the bottom wall of the channel material 4B.

In this state, the article locking member 10 has the lower edge of the lower extending piece 14Bb of the lower locking hook 14B elastically in the root portion side region of the support wall 11 with the base wall 12. Hold it. Further, at this time, the lower edge portion of the facing surface 15 of the base wall 12 comes into contact with the front surface of the pipe member 4A of the beam member 4 at a position below the downward extending piece 14Bb of the locking hook 14B. As a result, the collapse of the article locking member 10 is restricted. Further, at this time, the lower surface of the bent portion 18 at the lower end of the locking hook 14B also comes into contact with the bottom wall of the channel member 4B, so that the article locking member 10 is restricted from falling down.

As described above, in the article locking member 10 according to the present embodiment, a plurality of locking hooks 14A and 14B are provided so as to project from the facing surface 15 of the base wall 12 in the vertical direction and are provided on the support walls 11 and 11A. The structure is such that any of the suitable locking hooks 14A and 14B can be selectively locked. Therefore, in the case of the article locking member 10 of the present embodiment, one article locking member 10 can be applied to a plurality of types of support walls 11 and 11A having different specifications.

Further, in the article locking member 10 according to the present embodiment, the locking hook 14A on the upper side of the base wall 12 is more opposed to the facing surface 15 of the base wall 12 and the downward extending piece than the locking hook 14B on the lower side. The distance between the 14Ab and 14Bb is wide, and the extension lengths of the downward extension pieces 14Ab and 14Bb are short. Therefore, even if the lower locking hook 14B exists below the upper locking hook 14A, the upper locking hook 14A avoids interference between the support wall 11A and the lower locking hook 14B. Can be securely locked to the target support wall 11A.

Further, in the article locking member 10 according to the present embodiment, the lower locking hook 14B of the base wall 12 has a lower extending length of the lower extending pieces 14Ab and 14Bb than the upper locking hook 14A. It is formed long. In the case of the locking hook 14B having a long extension length of the downward extension piece 14Bb, a long engagement stroke with respect to the support wall 11 is required, but in the case of the article locking member 10 of the present embodiment, the lower side Since there is no other locking hook below the locking hook 14B, the work for locking the locking hook 14B to the support wall 11 and releasing the locking hook 14B can be easily performed.

Further, the article locking member 10 according to the present embodiment is, for example, the upper side having a short extension length of the downward extension piece 14Ab with respect to the thick support wall 11A in the front-rear direction as shown in FIG. The locking hook 14A is locked, and the lower locking hook 14B having a long extending length of the downward extending piece 14Bb is engaged with respect to the support wall 11 having a thin thickness in the front-rear direction as shown in FIG. It can be stopped. Therefore, even when a heavy target article such as a board material 5 is locked to the thin support wall 11 in the front-rear direction via the article locking member 10, the stress acting on the support wall 11 is increased. It can be suppressed and the deformation and runout of the support wall 11 can be prevented.

That is, the stress due to the load of the target article (board material 5) acting on the support wall 11 via the article locking member 10 is the thickness of the support wall 11 in the front-rear direction and the vertical direction of the locking hook 14B with respect to the support wall 11. It is almost determined by the product of the contact width (extending length of the downward extending piece 14Bb). However, in the article locking member 10 of the present embodiment, the extending length of the lower extending piece 14Bb of the lower locking hook 14B locked to the thin support wall 11 in the front-rear direction is on the upper side. It is set longer than the extension length of the downward extension piece 14Ab of the locking hook 14A. Therefore, even if the thickness of the support wall 11 in the front-rear direction is thin, the load can be received by the length of the support wall 11 in the vertical direction, and as a result, the increase in stress acting on the support wall 11 is suppressed. , It is possible to prevent deformation and runout of the support wall 11.

Further, in the article locking member 10 according to the present embodiment, the lower locking hook 14B protrudes rearward from the rear surface of the upper locking hook 14A, and the upper locking hook 14A has a support structure. A support surface 16a that can come into contact with the wall 21 of the support structure 40 when locked to the support wall 11A of the body 40 is provided. Therefore, when the upper locking hook 14A is locked to the support wall 11A of the support structure 40, the support surface 16a comes into contact with the wall 21 of the support structure 40 on the lower side of the upper locking hook 14A. As a result, the falling of the article locking member 10 and the target article is surely regulated.

Further, in the case of the article locking member 10 of the present invention, the support surface 16a that abuts on the wall 21 of the support structure 40 is provided at the rear end of the rear extending piece 14Ba of the lower locking hook 14B. The rear extension piece 14Ba, which extends rearward and has high support rigidity, can receive the load in the tilting direction of the article locking member 10. Therefore, when the article locking member 10 of the present embodiment is adopted, the fall of the article locking member 10 can be more reliably regulated when the target article is locked.

The present invention is not limited to the above embodiment, and various design changes can be made without departing from the gist thereof. For example, in the above embodiment, the article engaging portion 13 projects from the front surface of the base wall 12, but the article engaging portion does not necessarily have to project from the front surface of the base wall 12.
