1 to 11 show the first embodiment of the present invention. The slide rail locking mechanism according to the first embodiment relates to an improvement of the slide rail locking mechanism described in Japanese Patent Application Laid-Open No. 2015-2329035, which is described as a conventional example. First, the basic configuration of the slide rail locking mechanism will be described.

As shown in FIG. 1, the slide rail 1 includes, for example, a fixed rail 2 fixed to the main body S1 of the frozen reach-in showcase, a moving rail 3 fixed to the product shelf S2 of the frozen reach-in showcase S1, and a fixed rail 2. It has an intermediate rail 4 interposed between the moving rail 3 and the moving rail 3. Here, a rolling ball (not shown) is interposed between the upper and lower bent portions 21 of the fixed rail 2 and the upper and lower bent portions 41 of the intermediate rail 4, and also with the upper and lower bent portions 31 of the moving rail 3. A rolling ball is also interposed between the upper and lower bent portions 41 of the intermediate rail 4, whereby not only the intermediate rail 4 but also the moving rail 3 can slide in the front-rear direction.

The lock member 5 is made of synthetic resin, and the locking member 51 provided on the inner surface of the fixed rail 2, the operating member 52 that can be engaged with and detached from the locking member 51, and the operating member 52 are attached to the moving rail 3. It is composed of a base portion 53 to be attached and a shaft portion 54 that rotatably supports the operating member 52.

As shown in FIG. 2, the locking member 51 is formed of a plate extending vertically, has fitting protrusions 51c protruding outward, and has the fitting protrusions 51c above and below the fixed rail 2. It is fitted in the fitting hole 22. Further, a circular fitting hole 51b is provided substantially in the center of the locking member 51 in the vertical direction, and the fitting projection 23 of the fixed rail 2 is fitted into the fitting hole 51b. In this way, the locking member 51 is fixed to the inner surface of the fixed rail 2 by fitting the fitting protrusions 51c and 23 and the fitting holes 51b and 22. Further, a substantially trapezoidal lock block 51a is projected on the inner surface of the locking member 51. A locking projection 52d, which will be described later, is engaged with and disengaged from the lock block 51a.

As shown in FIG. 3, the operating member 52 extends rearward of the moving rail 3, and the grip portion 52a, the locking portion 52b, and the rotating portion extend rearward from the tip end side of the moving rail 3. It extends sequentially to 52c. The grip portion 52a is formed to be wide so that it can be easily operated by the operator's fingers. The locking portion 52b is formed with a substantially trapezoidal locking projection 52d protruding on the opposite side of the moving rail 3. Here, when the operating member 52 is in the locked state, the locking projection 52d is locked to the rear end of the lock block 51a as shown in FIG. 5, while the operating member 52 is in the unlocked state. As shown in FIGS. 6 and 7, the locking projection 52d is detached from the lock block 51a. Further, a quadrangular guide groove 52e is formed in the locking portion 52b.

The base portion 53 is a cross-linking member 53c that connects the shaft forming substrate 53a, the fitting mounting body 53b arranged vertically at intervals from the shaft forming substrate 53a, and the shaft forming substrate 53a and the fitting mounting body 53b. It has.

As shown in FIG. 3, the shaft forming substrate 53a is formed on the rear end side of the base portion 53, and is formed in a substantially inverted U shape in cross section. A pair of upper and lower elastic members 53d extending forward are formed on the front surface of the shaft forming substrate 53a, and an operating member 52 is arranged between the elastic members 53d (FIGS. 5 to 8).

As shown in FIG. 3, the fitting attachment body 53b is formed so as to correspond to the inner surface of the bent portion 31 of the moving rail 3, and is fitted inside the bent portion 31. Further, each fitting attachment body 53b has a fitting projection 53e extending along the moving rail 3 so as to be fitted into the fitting hole 32 formed in the bent portion 31.

In this way, the fitting attachment body 53b is fitted into the bent portion 31, and the fitting protrusion 53e is fitted into the fitting hole 32, so that the base portion 53 is fixed to the moving rail 3. Further, a thin guide plate 53f connecting the upper and lower ends is formed on the tip end side of each fitting mounting body 53b. A part of the guide plate 53f is located in the guide groove 52e of the operation member 52, and when the operation member 52 is operated, the guide groove 52e is guided along the guide plate 53f.

As shown in FIG. 3, the cross-linking member 53c is formed in a thin plate shape, and connects the rear end side of each fitting attachment body 53b to the shaft forming substrate 53a. Here, since the front end side and the rear end side of the fitting mounting body 53b are connected by thin plate-shaped members, when the fitting mounting body 53b is fitted into the bent portion 31 of the moving rail 3, the guide plate 53f and the bridge are bridged. Both the member 53c and the fitting mounting body 53b are elastically deformed so that the fitting mounting body 53b fits into the bent portion 31.

As shown in FIG. 3, the shaft portion 54 includes a columnar first shaft 54a formed on the base portion 53, a substantially columnar second shaft 54b formed on the inner surface of the moving rail 3, and an operating member 52. It is composed of a through hole 54c having a circular cross section. The first shaft 54a and the second shaft 54b are inserted from opposite directions of the through hole 54c, and the outer diameter dimension of the first shaft 54a and the second shaft 54b is slightly smaller than the inner diameter dimension of the through hole 54c. The operating member 52 is rotatably supported.

In the slide rail locking mechanism configured in this way, in the locked state of the operating member 52, as shown in FIG. 5, the operating member 52 is sandwiched by the upper and lower elastic members 53d and is in a horizontal state, and is locked. The protrusion 52d is locked to the rear end of the lock block 51a.

On the other hand, when the operating member 52 is unlocked, the operating member 52 is rotated upward or downward as shown by the white arrows in FIGS. 6 and 7. As a result, the locking projection 52d moves to a position where it can be detached from the lock block 51a, and as shown by the white arrow in FIG. 8, when the operating member 52 is pulled out forward, the product shelf S2 moves forward.

The detachment suppressing member 6a is formed on the side surface of the moving rail 3, and moves from the connecting portion 61 extending from the operating member 52 toward the outside of the moving rail 3 across the tip of the moving rail 3 and moving from the tip of the connecting portion 61. It has a restraining portion 62 extending toward the rear of the rail 3. The connecting portion 61 and the suppressing portion 62 are located with a gap from the moving rail 3 and are designed so as not to interfere with the moving rail 3 when the operating member 52 is rotated.

According to the first embodiment, the moving load when pulling out the product shelf S2 is very large, and due to this, even if the operating member 52 is accidentally pulled in the left-right direction, the operating member 52 moves in the left-right direction. Movement is suppressed by the detachment suppressing member 6a. That is, as shown in FIG. 9A, even if the operating member 52 is pulled in the right direction, the side surface of the operating member 52 is locked to the inner surface of the moving rail 3, and the operating member 52 moves to the right side. On the other hand, as shown in FIG. 9B, even if the operating member 52 is pulled toward the left side, the restraining portion 62 is locked to the outer surface side of the moving rail 3 and the left side of the operating member 52. Movement to is restricted.

Since the movement of the operating member 52 in the left-right direction is restricted as described above, the detachment load applied to the base 53 through the operating member 52 is suppressed, and the operating member 52 not only detaches from the base 5 but also accompanies the detachment of the base 5. Withdrawal is also suppressed.

FIG. 10 shows a first modification of the detachment suppressing member according to the first embodiment. The same structural parts as the detachment suppressing member 6a are omitted, and only different structural parts will be described below. In the description of the first modification, the same components as those in FIGS. 1 to 9 will be described using the same reference numerals.

The restraining portion 62 of the detachment suppressing member 6a extends parallel to the outer surface of the moving rail 3, but the restraining portion 63 according to the first modification approaches the outer surface of the moving rail 3 toward the rear of the moving rail 3. Is formed.

According to the detachment suppressing member 6b according to the first modification, even if the operating member 52 is pulled to the left side, the contact area between the suppressing portion 63 and the moving rail 3 becomes large as shown by the alternate long and short dash line, and the operation is performed.

In the description of the second embodiment, the same components as those in FIGS. 1 to 9 will be described using the same reference numerals.

In the shaft portion 54 according to the first embodiment, since the processing of the second shaft 54b is formed by pressing the moving rail 3, the tip of the second shaft 54b becomes a hemispherical surface as shown in FIG. ing. Therefore, the contact area between the outer surface of the second shaft 54b and the inner surface of the through hole 54c of the operating member 52 is reduced, and the second shaft 54b is easily pulled out. Focusing on such issues, the following configuration was adopted in the second embodiment.

Further, the second shaft 55b of the operating member 52 faces the moving rail 3 and is rotatably inserted into the second shaft hole 55d. With this configuration, the operating member 52 is supported by the shaft portion 55 and can be rotated in the vertical direction.

According to the second embodiment, since both the first shaft 55a and the second shaft 55b can be formed so as to be cylindrical and the tip is not hemispherical, even if a load is applied from the operating member 52 to the base 53, the base portion The 53 and the shaft portion 55 do not easily come off from the moving rail 3.

As described above, according to the second embodiment, the first axis 55a and the second axis 55b exert the function of suppressing the detachment of the base portion 53 and the operating member 52, so that the first axis 55a and the second axis 55b is configured as a detachment suppressing member 6d.

14 and 15 show a modification of the detachment suppressing member 61 according to the second embodiment. The same structural parts as the detachment suppressing member 6d are omitted, and only different structural parts will be described below. In the description of the modified example, the same components as those in FIGS. 1 to 9 will be described using the same reference numerals.

The second shaft 55b according to the second embodiment is only formed in a columnar shape, but the second shaft 55e according to the modified example is provided with a slit 55f extending in the axial direction, and the tip is formed in an umbrella shape. It is formed to have a diameter larger than the inner diameter of the biaxial hole 55d.

According to this modification, since the outer diameter of the second shaft 55e on the tip end side is larger than the inner diameter of the second shaft hole 55d, the second shaft 55e is hard to come off from the moving rail 3.

As described above, according to this modification, the first shaft 55a and the second shaft 55e exert the function of suppressing the detachment of the base portion 53 and the operating member 52, so that the first shaft 55a and the second shaft 55e are exhibited.

Since it is formed in, the base 53 can be stably held.
Further, the length dimension of the protrusion 59a is increased, and the protrusion 59a protrudes from the moving rail 3 by a predetermined length, so that even if the base portion 53 is slightly displaced due to an external load, the protrusion 59a Is difficult to pull out from the through hole 59b. This point also contributes to the improvement of the mounting strength of the base portion 53b.

FIG. 23 shows a modified example of the detachment suppressing member 6k according to the seventh embodiment. The same structural parts as the detachment suppressing member 6k are omitted, and only different structural parts will be described below. In the description of the modified example, the same components as those in FIGS. 1 to 9 will be described using the same reference numerals.

The detachment suppressing member 6L according to this modification has a retaining portion 59c facing the outer surface of the moving rail 3 and extending toward the rear of the moving rail 3 on the tip end side of the protrusion 59a.
