Description

The present invention relates to a slide rail used for an inclined shelf or a storage shelf provided at a high place.

Conventionally, a general slide rail has been devised in a direction that makes traveling of the moving rail in the pull-out direction as light as possible.
Therefore, if a conventional slide rail is used for an inclined shelf or the like (a shelf that has been lowered forward, or a drawer), the locked state of the inclined shelf that is maintained in a fully closed state by an automatic locking device is released. It suddenly starts moving in the pull-out direction (opening direction), accelerates, and hits the stopper when fully opened and stops at the maximum speed. For this reason, the stopper at the time of full opening may be damaged by the impact of the collision, or the operator may be in danger by sudden jumping out.

In order to prevent this, a slide rail in which the moving rail is automatically stored is used for an inclined shelf or the like by the restoring force of the spring member. (For example, refer to Patent Document 1.)
In this case, since the spring member is used, the greater the pull-out amount of the moving rail, the greater the restoring force of the spring member. Therefore, the initial release of the moving rail when the lock is released in the fully closed state If the movement side rail is not automatically pulled out and the movement side rail is automatically pulled out to its end by its own weight, it is possible to prevent the drawer from popping out when the lock is released. There wasn't.

On the other hand, a conventional automatic locking device can be unlocked by incorporating a lock mechanism and a release mechanism inside the slide rail and lightly pushing the front surface of the drawer, etc. There has been proposed one that automatically locks when the drawer is inserted to the back (slide rail having an automatic locking function). (For example, refer to Patent Document 2.)

In this case, two movable stoppers are provided corresponding to the outer rail and the inner rail, a fixed stopper is provided on the inner rail, and the push springs are individually attached to the outer rail. In addition to ensuring quality stability, the equipment is too large to be used for compact slide rails, and each component (two movable stoppers, fixed stoppers, and push springs) is used as a member. It is necessary to manage the parts, and the parts management becomes complicated. In addition, when a failure occurs in a normal slide rail, it is necessary to inspect, repair, and replace each member, and the entire slide rail can be replaced. there were.

The travel control device 80 is configured as described above, and is attached to the slide rail 100 and used for an inclined shelf or the like.
For example, as shown in FIG. 10, the inclined shelf 92 is connected between the left and right moving-side rails 2, 2, and is disposed in a front-down state on the inner surfaces of the side plates 91, 91 of the inclined shelf main body 90 whose front surface is open. When the slide rail 100 is in the most contracted state (the inclined shelf board 92 is accommodated in the inclined shelf body 90), the engaging member 7 is engaged with the engagement holding member 5, and the movable rail 2 is accommodated. The state (the storage state of the inclined shelf board 92) is maintained.
Then, when the stored inclined shelf 92 is pushed in the storage direction, the stored state is released, and the inclined shelf 92 (moving side rails 2 and 2) is stored in the inclined state in which the slide rails 100 and 100 are inclined downward. Because it is, it is self-propelled in the pulling direction.
At this time, since the traveling control device 80 is provided between the moving side rail 2 and the fixed side rail 1,
The inclined shelf plate 92 does not suddenly jump forward.

That is, when the moving side rail 2 (rack member 82) moves forward, the auxiliary pinion 85 that meshes with the rack member 82 has the substrate side turning center shaft 851 and the cover side turning center shaft 852, and the guide support groove 834 and the cover. Since it is fitted to the side guide support groove 864 so as to be rotatable and movable in the running direction, it is temporarily moved in the pull-out direction and meshed with the pinion 842 of the rotary damper 84. (The state shown in FIG. 13)
As a result, the auxiliary pinion 85 is controlled to rotate slowly. Therefore, the rack member 82 meshing with the auxiliary pinion 85 also moves slowly in the pull-out direction. Self-propelled in the pull-out direction, the moving rail 2 reaches the maximum extension state with respect to the fixed rail 1 and stops.

Next, when the inclined shelf plate 92 is moved from the most extended state in the storage direction, the auxiliary pinion 85 that meshes with the rack member 82 once moves in the storage direction, and the auxiliary pinion 85 is separated from the pinion 842 of the rotary damper 84. Then, the pinion 842 becomes non-rotating, the auxiliary pinion 85 rotates without resistance, and therefore the rack member 82 (moving side rail 2) also moves in the storing direction regardless of the rotary damper 84 (the state shown in FIG. 14). Soon, the push shelf device 93 maintains the inclined shelf board 92 (moving side rail 2) in the stored state.
In the embodiment, since a bi-directional rotary damper 84 (small and inexpensive) is used, an auxiliary pinion is required. However, a unidirectional rotary damper is used, and the pinion of the rotary damper is a rack member 82. You may make it mesh directly.
