Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a long object storage shelf for supporting and storing long objects.

BACKGROUND ART FIG. 1 shows a conventional long object storage side.
That is, a support frame 2 having a plurality of vertical frames 1 is provided at appropriate intervals in the left-right direction, support arms 3 in the front-rear direction are attached to a plurality of locations in the vertical direction of each vertical frame 1, and the front part of the support arm 3 is supported. It is constructed by protruding forward from the frame. A long object 4 is placed and stored between the support arms 3 adjacent in the left and right direction. According to such a conventional configuration, there is no problem when loading and unloading the long objects 4 using a forklift truck, but when loading and unloading the long objects 4 on the lower tier using a crane, for example, when handling the long objects 4 on the lower tier, there is no problem. The length 4 and the support arm 3 get in the way, making it impossible to perform the operation easily and safely. Therefore, as shown in the imaginary line in Figure 1, a configuration can be considered in which the lower support arms 3 are protruded forward so that they can be easily handled by a crane, but this not only makes it impossible to handle them by a forklift vehicle, but also The installation area of storage shelves will be expanded. To solve this problem, a pull-out shelf with a loading platform has been proposed, for example, as disclosed in Japanese Utility Model Application Publication No. 54-22931. This conventional type has a loading platform that is supported and guided by upper and lower rails provided on the shelf frame side and can slide freely, and by pulling out the loading platform and protruding forward from the shelf frame, loads can be loaded and unloaded from the loading platform. ing. A front locked part and a rear locked part are provided on the upper side of the loading platform, and a movable stopper that can be freely engaged with and detached from these locked parts is rotatably provided in the front part of the shelf frame. According to this, by arranging the movable stopper to face the front locked part when the loading platform is pushed in, it is possible to prevent the loading platform from inadvertently protruding. By arranging the movable stoppers to face each other, it is possible to prevent the loading platform from being inadvertently moved in and out.

Problems to be Solved by the Invention According to such a conventional slide type, when pushing the loading platform, the operator walks to the front side of the shelf frame, releases the movable stopper, and then pushes the front side of the loading platform. The work efficiency is poor because the loading platform must be pushed in after walking back to the side.Furthermore, if the loading platform is inadvertently retracted immediately after the movable stopper is released, it may cause damage to the area near the movable stopper. There is a risk of causing an unexpected situation for the workers in the room.

The purpose of the present invention is to provide a storage shelf for long objects that is of a sliding type and prevents accidental movement when being pulled out or pushed in, but which allows both stoppers to be released from the front side. It is in.

Means for Solving the Problems In order to achieve the above object, the long object storage shelf of the present invention is provided with a support frame having a plurality of vertical frames at appropriate intervals, and at multiple locations in the vertical direction of each vertical frame. A support arm is provided on each guide rail that is slidable between a position where it retracts into the guide rail and a position where the front part projects forward from the guide rail, and the front end of the support arm A control lever is swingably attached to the control lever, and a stopper body that is linked to the control lever is attached to the rear end of the support arm, and a drawer prevention stopper part, which can be freely engaged and detached, is attached to the rear end of the guide rail. A push-in prevention stopper portion is provided on the front end side of the guide rail, and a push-in prevention stopper portion is provided on the front end side of the guide rail, and the stopper member can be freely engaged and removed.

Effect: According to the configuration of the present invention, when the support arm is retracted into the guide rail, the stopped body faces the pull-out prevention stopper part, so that the support arm can be retracted so as not to protrude inadvertently. Positioned by position. When all the support arms are retracted, the long objects are stored, and at this time the long object storage shelf can be compacted. Also, in this state,
For example, long items can be loaded and unloaded using a forklift truck. When unloading a stored long object using a crane, for example, a support arm is protruded (pulled out) from the guide rail, and the long object supported by this support arm is placed in front of the long object on the other stage. to be located. This makes it easy and safe to unload long items using a crane. Loading work can also be carried out in the same manner. At this time, the body to be stopped faces the push-in prevention stopper portion, and the support arm is positioned at the protruding position so as not to be inadvertently retracted. When adjusting the movement from the retracted position to the extended position, the operator first stands in front of the long object storage shelf, swings the operating lever provided on the support arm, and in conjunction with this swings the object to be stopped. Pull out the support arm toward you while moving it to the non-stop position. To push in the support arm that has been pulled out, similarly, swing the operating lever from the front side of the support arm.
This is possible by moving the body to be stopped to the non-stopping position.

This is made possible by the support and guidance provided by the movable side guide rollers 23, 23 that come into contact with the inner surface of 5A. Three support arms 17 adjacent in the left and right direction form a set to support one elongated object 18,
Therefore, in the embodiment, there are three sets of support configurations. An operating lever 24 is attached to the front end of the support arm 17 located in the middle of each set so as to be swingable back and forth. In other words, the operating lever 24 is connected to the supported portion 24 of the upper horizontal rod.
A, the connecting part 24B of the vertical rod, and the operating part 24C of the lower horizontal rod form a C shape, and the supported part 24A is attached to the upper surface of the tip of the supporting arm 17 via the bearing body 25. It is rotatably mounted. Note that a slide operating tool 26 is provided on the lower surface side of the front end of the support arm 17. A stopped body 27 that is interlocked with the operating lever 24 is attached to the rear end of the support arm 17 . That is, the stopped body 27 is a link 30 whose intermediate portion is swingably attached to the bracket 28 from the support arm 17 via a horizontal pin 29.
and a roller 31 attached to the lower end of this link 30.
The upper end of the link 30 and the connecting portion 24B are connected by a rod 32. A spring 33 for biasing the roller 31 downward is provided between the upper end of the link 30 and the rear end of the support arm 17.
is interposed. A rail-shaped stopper 34 is attached to the side edge of the connecting plate 15B, and the rear end side vertical surface of this stopper 34 forms a pull-out prevention stopper section 34a, and the front end side vertical surface forms a push-in prevention stopper section 34b. is formed. Note that roller receiving plates 35a and 35b are provided consecutively from the lower surfaces of the rear end and the front end of the stopper 34 in the front-rear direction.

FIG. 3 shows the support arm 17 retracted into the guide rail 15. At this time, the spring 33
Due to the elastic force, the roller 31 moves downward as shown by the solid line, is received by the roller receiving plate 35a, and faces the pull-out prevention stopper part 34a. Thereby, the support arm 17 is positioned at the retracted position so as not to protrude inadvertently. When all the support arms 17 are retracted, the long objects 18 are stored, and at this time, the long object storage shelf can be compacted. Further, in this state, the long objects 18 can be loaded and unloaded using, for example, a forklift vehicle. When unloading the stored long object 18 using a crane, for example, the support arm 17 is projected (drawn out) from the guide rail 15 as shown in FIG. 4, and the long object supported by the support arm 17 is removed. 18 is positioned in front of the elongated object 18 on the other stage. This makes it easy and safe to unload the long object 18 using a crane. Loading work can also be carried out in the same manner. During this pulling out, the roller 31 moves downward and is received by the roller receiving plate 35b and faces the push-in prevention stopper part 34b, so that the supporting arm 17 is kept at the protruding position to prevent it from being inadvertently retracted. Positioned. Note that when adjusting the movement from the retracted position shown in FIG. 3 to the extended position shown in FIG. As shown by the imaginary line in FIG. 3, the operating portion 24c is swung so as to be located near the slide operating tool 26. As a result, rod 32
is pulled toward the front end side, which causes the link 30 to spring 33
3, and the roller 31 is moved upward to the non-stop position as shown by the imaginary line in FIG. Next, the support arm 17 is pulled out while grasping the operating portion 24c and the slide operating tool 26 at the same time. At this time, since the support arms 17 on both sides do not have a stopper structure, they are pulled out integrally with the elongated object 18 toward the front. The pulled-out support arm 17 can be pushed in in the same way by pressing the operation lever 2 from the front side of the support arm 17.
This is possible by swinging the stopper 4 and moving the stopper body 27 to the non-stopper position as shown by the imaginary line in FIG.

Effects of the invention According to the invention having the above configuration, the following effects can be expected. In other words, since the support arm is retracted into the guide rail in the normal storage state, the installation area can be minimized, and furthermore, in this state, loading and unloading with a forklift vehicle can be carried out easily and safely. It can be carried out. In addition, loading and unloading using a crane can be done easily and safely by pulling out (protruding) the support arm of the tier forward from the guide rail, without being obstructed by long objects or support arms from the upper tier. can be done. In particular, according to the present invention, the support arm in the protruding position can be positioned by the engagement of the stopped body with the push-in prevention stopper part, so that the loading and unloading work can be performed stably, while the support arm is not engaged. The release operation can be performed via the operating lever provided at the front end of the supporting arm.This allows the operating lever to be operated from the frontmost side regardless of the state of the supporting arm, improving workability and safety. You can improve.
