An embodiment of the present invention will be described in detail with reference to the drawings. As an example, a latch 10 according to the present invention includes a pair of shelf columns 2R for receiving a shelf board 1 as shown in FIG. Although it is shown that it also serves as a shelf holder for latching to 2L (hereinafter collectively referred to by reference numeral 2), the latching tool 10 of the present invention is not limited to this shelf holder, but a horizontal type as shown in FIG. The hanger pipe holder for supporting the hanger pipe 3 and the hanger pipe holder for supporting the vertical hanger pipe 4 having a plurality of hanger hooks as shown in FIG. 18 can also be applied. The support S to be used may be a side wall having one to multi-stage retaining holes such as a metal cabinet other than the shelf columns as shown in FIGS.

As shown in FIGS. 2 and 3, the latching tool 10 of the present invention latches on a latching portion 12 in the form of a latching hole 12 H provided in a pair of shelf columns 2 R and 2 L as a support S. A latch body 14 having a multi-stage hook 14F to be lifted, and a lifting prevention position PP for preventing the latch body 14 from being lifted by engaging with the latch hole 12H in which the latch body 14 is latched. (Position of FIG. 3, FIG. 7C and FIG. 8A) and a lifting allowance position AP (position of FIG. 8B) that allows the lifting tool body 14 to be lifted off the latching hole 12H. And a urging means 30 for urging the lifting preventing member 20 to the lifting preventing position PP.

1 and 9, since the latch body 14 is in the form of a shelf holder, it has a receiving plate portion 14R for receiving the shelf board, and in the illustrated form, it has four stages of hooks 14F. As long as at least one hook 14F is provided, the number of hooks 14 may be other than four.

As shown in FIGS. 2, 3, and 6, the lifting prevention member 20 includes a pair of substantially C-shaped wall plates 22 R and 22 L, and these wall plates 22 R and 22 L have C-shaped openings. Are integrally attached to each other with the upper and

lower protrusions

24U and 24L between the two tips. One wall plate 22R has a leg portion 22RC extending so as to close the C-shaped opening, and a short pivot shaft for pivotally supporting the lifting preventing member 20 on the latch body 14 at an intermediate portion of the leg portion. 16

As shown in FIG. 8 (B ′), the lifting prevention member 20 is formed on the second stage of the latch body 14 so that the plate portion of the latch body 14 enters between a pair of

wall plates

22R, 22L. It is pivotally supported by a pivot shaft 16 and attached to a pivot hole 14H (see FIG. 5) near the eye hook 14F.

The upper projecting piece (hereinafter referred to as the upper projecting piece) 24U is latched by the urging means 30 in a state where the latching tool body 14 is latched in the latching hole 12H of the shelf column 2, as will be described later. It engages in the same latching hole 12H so as to overlap the hook 14F of the tool body 14 (see FIGS. 7C and 8A) and has a function of preventing the latch tool body 14 from lifting. The function of the lower projecting piece 24L will be described later in detail in connection with the temporary fixing release.

In the first embodiment, the urging means 30 includes a coiled spring 30S that engages with the inner surface (the right surface in FIG. 6E or the left surface in FIG. 6F) of the upper projecting piece 24. The spring 30S is disposed in a recessed spring receiver 14SR (see FIG. 5) of the latching tool body 14, and normally, the upper protrusion piece 24U is formed around the pivot shaft 16 with the lifting preventing member 20 as a center. It is biased in the direction toward the front latching hole 12H (counterclockwise in FIG. 6E). Therefore, as shown in FIG. 3, the upper protrusion piece 24U of the lifting preventing member 20 is engaged by the urging means 30 into the latch hole 12H in which the hook 14F is latched, so that Prevents lifting.

In order to remove the latch main body 14 from the shelf column 2, the latch 10 of the present invention is pivoted in the clockwise direction in FIG. Temporary fixing means 40 is further provided for temporarily fixing and holding at a lifting allowable position AP that is retracted and removed from the stop hole 12H.

As shown in FIGS. 6C, 6C, 6D, and 6D, the temporary fixing means 40 includes shallow temporary fixing protrusions 42 provided on opposing surfaces of the pair of

wall plates

22R and 22L. These temporary fixing protrusions 42 provided on the latching tool main body 14 are formed with hole-shaped temporary fixing recesses 44 (see FIG. 5) which are engaged at the lifting allowable position AP of the lifting prevention member 20. In the form shown in the figure, an arc-shaped relief groove 46 (see FIG. 5) is provided in the latching tool main body 14 so that the temporary fixing projection 42 is moved in a resistanceless manner within the range in which the lifting prevention member 20 pivots. The temporary fixing recess 44 is provided in a state of being bent continuously at the end of the arc-shaped escape groove 46. Accordingly, until the lifting prevention member 20 moves from the lifting prevention position PP to the lifting allowable position AP against the biasing means 30, the temporary fixing protrusion 42 moves in the arc-shaped escape groove 46, and the lifting prevention member 20 is moved. Reaches the allowable lifting position AP, the temporary fixing protrusion 42 enters the bent temporary fixing recess 44, and the lifting preventing member 20 is temporarily fixed and held at the allowable lifting position AP.

The latching tool 10 of the present invention further includes a temporary fastening release means 50 for releasing the temporary fastening of the lifting preventing member 20 by the temporary fastening means 40 when the latching tool body 14 is lifted.

When the latch main body 14 is lifted, the temporary lock release means 50 moves the latch main body 14 relative to the support S by the lifting operation so that the lifting prevention member 20 is pushed relative to the support S temporarily. The stop protrusion 42 is forcibly removed from the temporary fixing recess 44 to release the lifting prevention member 20 from the temporary fixing position. In the illustrated embodiment, the force for releasing the lifting prevention member 20 from the temporarily fixed position is such that the lower protruding piece (hereinafter referred to as the lower protruding piece) 24L is applied to the lower stage of the support at the temporarily fixed position of the lifting preventing member 20. Since the latching tool body 14 is lifted because it is engaged with and hooked into the retaining hole 12H (see FIG. 8B), the lower projecting piece 24L is relatively positioned on the upper wall surface of the lower retaining hole 12H. Occurs when pressed. Therefore, when the latching tool main body 14 is lifted, the lifting preventing member 20 is pushed so that the upper protruding piece 24U faces the lifting preventing position PP with the pivot shaft 16 as the center. 44 is forcibly removed and the temporary fixing is released. In this case, as shown in FIG. 8C, the upper projecting piece 24U comes off the facing surface of the latching hole 12H and abuts against the wall surface without the latching hole 12H of the support S. The main body 14 is not returned to the lifting prevention position AP.

In the illustrated embodiment, the lower protruding piece 24L of the temporary fixing release means 50 is hooked on the upper wall surface of the lower locking hole 12H to release the temporary locking. A hook hole or a recess is provided between which the lower protrusion piece 24L is hooked in a temporarily fixed state, and the lower protrusion piece 24L of the lifting preventing member 20 is relatively pushed by the hook hole or recess when the hook body 14 is lifted. The lifting prevention member 20 may be released from the temporarily fixed state. In the present specification, the lower latching holes 12H, the catching holes, or the recesses to which the lower projecting pieces 24L are caught are collectively referred to as the catching portions.

Next, the operation of hooking and hanging the latching tool 10 according to the above embodiment of the present invention on the shelf column 2 will be described with reference to FIGS.

First, the work of latching the latching tool 10 on the shelf column 2 will be described. As shown in FIG. 7A, the hook 14F of the latching tool body 14 is latched on the shelf column 2 which is the support S. These hooks 14F are hidden in the latching holes 12H of the shelf columns 2 so as to be aligned with the holes 12H, and the tip portions of the hooks 14F are pushed into the inside of the shelf columns 2 as shown in FIG. Thereafter, as shown in FIG. 7C, when the latch body 14 is lowered until the recess 14FR (see FIG. 2) of the hook 14F is received by the lower wall surface of the latch hole 12H of the shelf column 2, it is prevented from being lifted. The upper projecting piece 24U of the member 20 is engaged in the empty space above the corresponding latching hole 12H by the spring bias of the biasing means 30. Therefore, the hook 14F of the latching tool main body 14 is restrained by the upper projecting piece 24U and cannot be lifted upward, so that the latching tool main body 14 is prevented from being lifted.

Next, when the latching tool main body 14 (see FIGS. 7 (C) and 8 (A)) that is latched in the latching hole 12H of the shelf column 2 in the state of being prevented from being lifted as described above, As shown in FIG. 8 (B), the lifting preventing member 20 is pivoted about the pivot shaft 16 in the clockwise direction in FIG. Retract from the latch hole 12H of the shelf column 2. In this way, when the upper protrusion 24 of the lifting prevention member 20 is removed from the latching hole 12H, the temporary fastening means 40 provided on the lifting prevention member 20 of the temporary fastening means 40 as shown in FIG. Therefore, even if the hand is released from the lifting member 20, the lifting preventing member 20 does not return to the lifting preventing position PP. Accordingly, the operator lifts the latching tool body 14 and moves up through the empty space above the latching hole 12H to the position where the hook 14F passes through the latching hole 12H through the state shown in FIG. 8C. Can be removed to the outside of the shelf column 2 through the latch hole 12H, and the latch body 14 can be removed from the shelf column 2.

8B and 8C, when the lifting prevention member 20 is pivoted from the lifting prevention position PP to the lifting allowable position AP, the lower protrusion 24L of the lifting prevention member 20 is engaged with the lower latching hole 12H. (See FIG. 8 (B)), when the latch body 14 is lifted, the lower projecting piece 24L collides with the upper wall surface of the lower latch hole 12H. As the lift rises, the lifting prevention member 20 is pushed relatively to the upper wall surface of the latching hole 12H and pivots counterclockwise in FIG. It escapes from the temporary fixing recess 44 and enters the escape groove 46. Therefore, the temporarily preventing state of the lifting preventing member 20 is released, and the latching tool body 14 can be prepared for the next latching operation as shown in FIG.

As can be seen from FIGS. 6 (E), (F) and FIG. 8 (C), the lower protruding piece 24L is thinner than the upper protruding piece 24U, and the lifting preventing member 20 is in the temporary fixing position, so that the lower protruding piece is latched. Even if it engages with the hole 12H, the lower protrusion 24L is loosely engaged with the lower latching hole 12H, and therefore the lifting tool body 14 is not prevented from being lifted. Further, when the temporary fixing protrusion 42 of the temporary fixing means 40 is engaged with the temporary fixing recess 44 at the time of temporary fixing or when the temporary fixing recess 44 is released from the temporary fixing recess 44 at the time of releasing the temporary fixing, the temporary fixing recess 44 is in contact with the escape groove 46. Since it is bent, there is a slight resistance, but since the temporary fixing protrusion 42 is formed thin, the operator only needs to apply a slight force to overcome this resistance.

A second embodiment of the present invention is shown in FIGS. In this embodiment, the temporary fixing protrusion 42 of the temporary fixing means 40 is engaged with the hole-shaped temporary fixing recess 44 of the latching tool main body 14 at the temporary fixing position, but at the non-temporary fixing position, the latching tool main body 40 is engaged. 14 is the same as the first embodiment of FIGS. 2 to 8 except that it slides elastically on the plate surface. FIGS. 10 and 11 are views for explaining the operation of attaching and detaching the latching tool body 14 corresponding to FIGS. 7 and 8 of the first embodiment. Normally, the upper protrusion piece 24U of the lifting prevention member 20 is released from the temporary fixing recess 44 by the spring 30S of the biasing means 30 and enters the latching hole 12H of the shelf column 2 and is biased to the lifting prevention position, thereby preventing the lifting prevention member. When 20 is lifted, it is engaged in the temporary fixing recess 44 and the lifting preventing member 20 is temporarily fixed at the lifting allowable position. Therefore, in this embodiment, the lifting prevention member 20 is subjected to sliding resistance with the plate surface of the latching tool main body 14 at a position other than the temporary fixing position, as compared with the first embodiment. Thus, the smoothness of the movement of the lifting preventing member 20 between the lifting preventing position and the lifting allowable position is low. The operation for releasing the temporary fixing is the same as that in the first embodiment. In this embodiment, the pair of

wall plates

22R and 22L of the latching tool body 14 are elastically coupled in a direction approaching each other. Therefore, when the temporary fixing protrusion 42 faces the temporary fixing recess 44, the temporary fixing protrusion 42 automatically enters the temporary fixing recess 44.

A third embodiment of the present invention is shown in FIGS. In this embodiment, the urging means 30 is not the coiled spring in the first and second embodiments, but includes a spring piece 30P integrally provided below the lifting prevention member 20. It can be set as the structure similar to 1st and 2nd embodiment. More specifically, the lifting prevention member 20 is composed of two substantially S-shaped

wall plates

22R and 22L fixed together via upper and lower projecting

pieces

24U and 24L, and the spring piece 30P is provided on the right side. The spring piece 30P is formed so as to rise obliquely upward continuously from the S-shaped lower part of the wall plate 22R, and the spring piece 30P is a latching tool positioned between the

wall plates

22R and 22L of the lifting prevention member 20. Engaging with the wall surface 14DW of the recess 14D of the main body 14, the wall surface 14DW urges the entire lifting prevention member 20 to pivot about the pivot shaft 16 in the counterclockwise direction of FIGS. . The lower projecting piece 24L is fixed between an extension piece 22RE extending forward (left side in FIG. 13) from the spring piece 30P of the wall plate 22R and an S-shaped lower plate piece 22LL of the wall plate 22L. The spring piece 30P has a thickness slightly larger than the thickness of the main body of the wall plate 22R, and the spring piece 30P slightly protrudes from the inner surface of the wall plate 22R. When the latching tool main body 14 is inserted into the latching member main body 14, when the gap between the

wall plates

22R, 22L is widened and the spring piece 30P is positioned in the recess 14D of the latching tool main body 14, the wall plate 22R, The interval of 22L becomes narrow as originally, and the spring piece 30P is engaged with the wall surface 14DW of the recess 14D.

The latching operation (FIG. 14) and the latching operation of the latching tool 10 according to the third embodiment are also the first and first except for the movement of the biasing means 30 that biases the lifting prevention member 20 to the lifting prevention position. This is the same as the second embodiment. As shown in FIG. 14A, before the latching starts, the spring piece 30P kicks the wall surface 14DW of the dent 14D of the latching tool body 14 and displaces the lifting preventing member 20 counterclockwise in FIG. However, when the latching is started and the hook 14F is engaged with the latching hole 12H and the upper projecting piece 24U is engaged with the shelf column 2, the spring piece 30P is pressed against the wall surface 14DW (FIG. 14B). D)). When the hook 14F is lowered until it engages with the lower surface of the latching hole 14H, the upper projecting piece 24U faces the space above the latching hole 12H, so that the spring piece 30P kicks the wall surface 14DW and the upper projecting piece 24U is hooked by the hook 14F. The lifting preventing member 20 is pivoted counterclockwise in FIG. In order to hang the latch 10, as shown in FIG. 15 (B), when the lifting prevention member 20 is pivoted to the lifting allowable position and temporarily fixed by the engagement of the temporary fixing protrusion 42 and the temporary fixing recess 44. As shown in FIGS. 15B and 15D, the spring piece 30P is pressed against the wall surface 14DW, but the temporary locking means 40 does not prevent the lifting preventing member 20 from lifting the hook 14F. Other operations are the same as those in the first and second embodiments.

According to the present invention, the lifting prevention member is normally in a position to prevent the lifting tool body from being lifted. However, when the lifting tool body is removed from the support, the lifting prevention member is opposed to the biasing means. Since it can be temporarily fixed to a position that allows the lifting tool body to be lifted, the lifting prevention member is removed from the lifting prevention position, and the latching tool body is removed from the support while being temporarily fixed to the lifting permission position. Therefore, it is not necessary to manually hold the lifting prevention member at the lifting allowable position, and the workability of removing the latching tool is improved, and the industrial applicability is high.
