It is fitted in the fitting hole 22. In addition, a circular fitting hole 51b is provided at a substantially vertical center of the locking member 51, and the fitting protrusion 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 the fitting of the fitting protrusions 51 c and 23 and the fitting holes 51 b and 22. Further, a substantially trapezoidal lock block 51 a is projected from the inner surface of the locking member 51. A locking projection 52d, which will be described later, is engaged and disengaged from the lock block 51a.

  As shown in FIG. 3, the operation member 52 extends toward the rear of the moving rail 3, and from the front end side of the moving rail 3 toward the rear, the gripping portion 52 a, the locking portion 52 b, and the rotating portion. 52c and sequentially extending. The grip portion 52a is formed wide so that it can be easily operated with the fingers of the operator. The locking portion 52b is formed with a substantially trapezoidal locking protrusion 52d that protrudes on the opposite side of the moving rail 3. Here, when the operating member 52 is in the locked state, as shown in FIG. 5, the locking projection 52d is locked to the rear end of the lock block 51a, and on the other hand, when 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 rectangular guide groove 52e is formed in the locking portion 52b.

  The base 53 includes a shaft forming substrate 53a, a fitting attachment body 53b disposed above and below the shaft forming substrate 53a, and a bridging member 53c that connects the shaft forming substrate 53a and the fitting attachment body 53b. It has.

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

  As shown in FIG. 3, the fitting attachment body 53 b 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. Each fitting attachment body 53 b has a fitting protrusion 53 e extending along the moving rail 3 and is fitted into the fitting hole 32 formed in the bent portion 31.

  Thus, since the fitting attachment body 53b fits into the bent portion 31 and the fitting projection 53e fits into the fitting hole 32, the base portion 53 is fixed to the movable rail 3. In addition, a thin guide plate 53f having upper and lower ends connected to each other is formed on the front end side of each fitting attachment 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 bridging 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 attachment body 53b are connected by thin plate members, when the fitting attachment body 53b is fitted into the bent portion 31 of the moving rail 3, the guide plate 53f, the bridge Both the member 53c and the fitting attachment body 53b are elastically deformed, and the fitting attachment body 53b is fitted into the bent portion 31.

The first shaft 54a and the second shaft 54b are inserted from opposite directions of the through hole 54c, and the outer diameter of the first shaft 54a and the second shaft 54b is slightly smaller than the inner diameter of the through hole 54c. The operating member 52 is rotatably supported.

  In the slide rail locking mechanism configured as described above, when the operating member 52 is locked, as shown in FIG. 5, the operating member 52 is sandwiched between the upper and lower elastic members 53d and is in a horizontal state. The protrusion 52d is engaged with the rear end of the lock block 51a.

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

  Although the basic configuration of the slide rail locking mechanism has been described above, the present invention is characterized in that a detachment suppressing member is provided in the locking mechanism.

  That is, as shown in FIGS. 1 and 3, a substantially L-shaped detachment suppressing member 6 a is formed in the locking portion 52 b of the operation member 52. The separation suppressing member 6 a is formed on the side surface of the moving rail 3, and moves from the operating member 52 across the tip of the moving rail 3 toward the outside of the moving rail 3 and from the tip of the connecting portion 61. And a restraining portion 62 extending toward the rear of the rail 3. The connecting portion 61 and the restraining portion 62 are positioned with a gap from the moving rail 3 and are designed not to interfere with the moving rail 3 when the operating member 52 is rotated.

That is, as shown in FIG. 9A, even if the operation member 52 is pulled in the right direction, the side surface of the operation member 52 is locked to the inner surface of the moving rail 3, and the movement of the operation member 52 to the right side is prevented. On the other hand, as shown in FIG. 9B, even if the operation member 52 is pulled in the left direction, the restraining portion 62 is locked to the outer surface side of the moving rail 3, and the left side of the operation member 52 Movement to is regulated.

  Since the movement of the operation member 52 in the left-right direction is restricted as described above, the detachment load applied to the base 53 through the operation member 52 is suppressed, and the operation member 52 accompanying the detachment of the base 5 as well as the detachment of the base 5 is suppressed. The withdrawal of is also suppressed.

  FIG. 10 shows a first modification of the separation suppressing member according to the first embodiment. The same components 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 part 62 of the separation restraining member 6a extends in parallel with the outer surface of the moving rail 3, but the restraining part 63 according to the first modification approaches the outer surface of the moving rail 3 as it goes to the rear of the moving rail 3. Is formed.

  According to the disengagement suppressing member 6b according to the first modified example, even when the operation member 52 is pulled to the left side, as shown by the two-dot chain line, the contact area between the suppressing portion 63 and the moving rail 3 is increased, and the operation is reduced.

The same constituent parts as those of the detachment suppressing member 6d are omitted, and only different structural parts will be described below. In the description of the modification, 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. The diameter is larger than the inner diameter of the biaxial hole 55d.

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

  As described above, according to this modification, the first shaft 55a and the second shaft 55e exhibit the function of suppressing the detachment of the base 53 and the operation member 52 by the first shaft 55a and the second shaft 55e. Is configured as a detachment suppressing member 6e.

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

  The separation suppressing members 6a, 6b, and 6c according to the first embodiment are formed on the operation member 52, and the separation suppressing members 6d and 6e according to the second embodiment are formed on the shaft portion 55. The separation suppressing member 6f according to the embodiment is formed of a rib between the shaft forming substrate 53a of the base portion 53 and each fitting attachment body 53b.

  According to the third embodiment, since the shaft forming substrate 53a and each fitting attachment body 53b are integrally connected by the ribs and the strength on the shaft forming substrate 53a side is reinforced, deformation on the shaft forming substrate 53a side is suppressed. Is done. Thereby, even if a load in the left-right direction is applied from the operation member 52, the influence on the shaft portion 54 is small, and the base 53 and the operation member 52 are prevented from being detached.

The shaft portion 56 has a metal screw 56d, passes through the first shaft hole 56a and the second shaft hole 56b, and passes through the third shaft hole 56c with screws.

  According to the fourth embodiment, even if a deformation load is applied from the operation member 52, the strength of the shaft portion 56 is increased by the metal screw 56 d, so that the base portion 53 and the operation member 52 are detached from the moving rail 3. There is nothing to do. Further, since the connection by the screw 56d is strong, the attachment strength of the base 53 to the moving rail 3 is high, and for example, a connection structure between the fitting protrusion 53e and the fitting hole 32 can be made unnecessary. Also, the separation restraining members 6a, 6b, 6c formed on the operation member 52 are not necessary, and the lock structure is simplified.

  As described above, according to the fourth embodiment, the metal screw 56d functions to suppress the detachment of the base 53 and the operation member 52. Therefore, the screw 56d itself is configured as the detachment suppressing member 6g. Yes.

  FIG. 20 shows a locking mechanism according to the fifth embodiment. The same components as those in the first embodiment are omitted, and only different structural portions will be described below.

The metal rivets 57d are passed through the shaft holes 57a, 57b, and 57c, and the tip is caulked and fixed to the outer surface of the movable rail 3.

  According to the fifth embodiment, even if a deformation load is applied from the operation member 52, the strength of the shaft portion 57 is increased by the metal rivet 57 d, so that the base portion 53 and the operation member 52 are detached from the moving rail 3. There is nothing to do.

  As described above, according to the fifth embodiment, the metal rivet 57d functions to suppress the detachment of the base 53 and the operation member 52, and thus the rivet 57d itself is configured as the detachment suppression member 6i. Yes.

  FIG. 21 shows a locking mechanism according to the sixth embodiment. The same components as those in the first embodiment are omitted, and only different structural portions will be described below. In the description of the sixth embodiment, the same components as in FIGS. 1 to 9 will be described using the same reference numerals.

  The shaft portion 58 according to the sixth embodiment includes a first shaft hole 58 a that penetrates the base portion 53, a second shaft hole 58 b that also penetrates the operation member 52, and a third shaft hole 58 c that penetrates the moving rail 3. The shaft holes 58a, 58b, and 58c are sequentially formed, and synthetic resin shafts 58d are passed through the shaft holes 58a, 58b, and 58c. The tip of the shaft 58d is formed in an umbrella shape so as to have a larger diameter than the inner diameter of the third shaft hole 58c, and a slit 58e extending in the axial direction is provided on the tip side of the shaft 58d.

  According to this embodiment, since the outer diameter of the tip side of the shaft 58d is larger than the inner diameter of the third shaft hole 58c, the shaft 58d is difficult to be detached from the moving rail 3.

  Thus, according to this modification, the shaft 58d is configured as the detachment suppressing member 6j in order to exhibit the function of suppressing the detachment of the base 53 and the operation member 52 by the shaft 58d.

  FIG. 22 shows a locking mechanism according to the seventh embodiment. The same components as those in the first embodiment are omitted, and only different structural portions will be described below. In the description of the seventh embodiment, the same components as in FIGS. 1 to 9 will be described using the same reference numerals.

  In each of the embodiments described above, when the base 53 is attached to the moving rail 3, the fitting protrusion 53 e of the fitting attachment body 53 b is fitted into the fitting hole 32 of the moving rail 3. However, since the fitting attachment body 53b is connected via the elastic bridging member 53c, the connection strength between the fitting protrusion 53e and the fitting hole 32c tends to be lowered by the elasticity. In the seventh embodiment, in order to solve such a problem, the separation suppressing member 6k is formed on the shaft forming substrate 53a that is not easily affected by the elastic force of the bridging member 53c.

  That is, a protrusion 59a is formed at a position facing the moving rail 3 on the shaft forming substrate 53a, and a through hole 59b through which the protrusion 59a passes is formed in the moving rail 3. Here, the length dimension of the protrusion 59a is designed to protrude from the outer surface of the movable rail 3 over a predetermined length when the protrusion 59a passes through the through hole 59b.

According to the seventh embodiment, when the protrusion 59a penetrates the through hole 59b, the movement of the base 53 in the front-rear direction is suppressed, and the protrusion 59a is less susceptible to the elastic force of the bridging member 53c. Therefore, the base 53 can be stably held.
Further, the length of the projection 59a is increased, and the projection 59a protrudes from the movable rail 3 by a predetermined length, so that even if the base 53 is slightly displaced due to an external load, the projection 59a is slightly displaced. Is difficult to be removed from the through hole 59b. This also contributes to an improvement in the mounting strength of the base 53b.

  FIG. 23 shows a modified example of the separation suppressing member 6k according to the seventh embodiment. The same components as the separation suppressing member 6k are omitted, and only different structures will be described below. In the description of the modification, 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 detachment preventing portion 59c facing the outer surface of the moving rail 3 and extending toward the rear of the moving rail 3 on the tip side of the protrusion 59a.

  According to this modified example, since the detachment preventing portion 59c is provided, the separation of the base portion 53 is completely prevented.

  Although various embodiments and modifications have been described above, it goes without saying that the present invention is not limited to this. Although not shown below, other examples will be given.

  For example, although the detachment suppressing member 6a according to the first embodiment is resin-molded integrally with the operation member 52, after the detachment suppressing member 6a is formed as a separate body, it is bonded or screwed to the operation member 52. It may be fixed. Moreover, in order to make the opposing area of the control part 62 and the movement rail 3 of the detachment | leave control member 6a large, you may make it form the control part 62 wide.
