  EMBODIMENT OF THE INVENTION The form for implementing the movable shelf apparatus with a safety bar which concerns on this invention is demonstrated below based on an Example.

(1) The overall configuration of the movable shelf device 1 with a safety bar will be described.
Referring to FIG. 1, the movable shelf device 1 with a safety bar includes a fixed shelf 4 at both ends placed on a rail 3 and a plurality of movable shelves 5. The rail 3 is laid on the floor 2, and the fixed shelf 4 is fixed to the floor 2. In the fixed shelf 4 and the movable shelf 5, a plurality of shelf plates 9 are attached to a support column (support member) 8. Side covers 11 are provided on the left and right sides of the fixed shelf 4 and the movable shelf 5. An overturn prevention member 10 is provided on the upper part of the movable shelves 5 and 5 to prevent the movable shelves 5 and 5 from falling due to shaking such as an earthquake.

  When the switch 12 of the movable shelf 5 is pressed, an electric motor and a transmission mechanism (not shown) are driven and the wheels 66 (FIG. 2 and the like) rotate, so that the movable shelf 5 moves from left to right on the rail 3, A passage S is formed between the fixed shelves 4 and the movable shelves 5 or between the movable shelves 5 and 5. In an emergency, the movable shelf 5 can be moved by rotating the handle 13. A safety bar 14 is provided below the lowermost shelf 9 of the fixed shelf 4 and the movable shelf 5. Details of the safety bar 14 will be described later.

  In the state shown in FIG. 1, when a switch for moving to the right of the switches 12 on the leftmost moving shelf 5 is pressed, the control device (not shown) moves the three moving shelves 5 on the left side to the right. When the limit switch 88 detects contact, the movement of the movable shelf 5 is stopped. By this movement, a passage S is formed between the left fixed shelf 4 and the adjacent movable shelf 5. When moving the three movable shelves 5, 5, 5, the electric motors of the respective movable shelves 5, 5, 5 may be driven, or only the electric motor of the leftmost moving shelf 5 may be driven.

(2) The configuration of the base 6 will be described.
2 and 3, the base 6 has a pair of steel plates having a U-shaped cross section, and the intermediate plates 60f2 and 60r2 of the front and rear frames 60f and 60r are directed in the front-rear direction, and are located inside the upper plates 60f1 and 60r1, respectively. The upper plates 62R1, 62L1, 62R1, and 62L1 of the left and right frames 62R, 62L, 62R, and 62L, which are two pairs of U-shaped steel plates that are substantially half in the vertical direction, are the intermediate plates 62R2, 62L2, 62R2, and 62L2. Are fixed by welding so as to face each other.

  Holders 63R and 63L for holding the bearings 65 are fastened and fixed to the lower plates 62R3 and 62L3 of the steel plates 62R and 62L by screws. A rotating shaft 67 of a wheel 66 is attached to the bearing 65. Although not shown, the rotary shaft 67 is provided with a mechanism for transmitting power from the electric motor or the transmission mechanism of the handle 13, and the rotary shaft 67 and the wheel 66 are rotated by driving the electric motor or operating the handle 13. . The wheels 66 are provided with hooks on both sides so as to prevent the wheels 66 from dropping off.

  On the upper plates 60f1 and 60r1 of the front and rear frames 60f and 60r, a fitting 68 (FIG. 3), which is a steel plate having a reverse hat cross section, is fixed by welding in accordance with the position of the opening 60r1h (FIG. 4). The support column 8 is fastened and fixed to the fixture 68 by screws (not shown). Safety bars 14f and 14r are swingably attached to the front and rear of the intermediate plates 62f2 and 62r2 of the front and rear frames 60f and 60r.

(3) The configuration of the safety bar 14 will be described.
With reference to FIGS. 2 and 4 to 7, the safety bars 14 f and 14 r have a line-symmetric configuration, and therefore the safety bar 14 r that is swingably attached to the rear frame 60 r will be mainly described. The safety bar 14r is fixed by a screw 82 below the plate-like portion 15r, the hook 16 provided on the back surface of the plate-like portion 15r, and the intermediate plate 60r2 of the rear frame 60r, and detects that the plate-like portion 15r is displaced more than a predetermined amount. Position sensor 80 (displacement detector), and a mounting cone spring 84 (elastic body) provided between the front frame 60f and the plate-like portion 15f. In FIG. 5, the left moving shelf 5 is cut away at a position where the mounting cone spring 84 can be seen, and the right moving shelf 5 is cut away at a position where the position sensor 80 can be seen. The mounting cone spring 84 is a coil spring having a radius that increases toward the plate-like portion 15f. The mounting side of the mounting cone spring 84 has a smaller radius than the screw head of the screw 84B. A screw 84B is inserted into a hole (not shown) of the mount cone spring 84 and the front frame 60f2 and fastened by a nut 84A from the back side of the front frame 60f2, thereby fixing the mount cone spring 84 to the front surface of the front frame 60f2. Note that the elastic body may be a sponge shown in FIG.

(3-1) The plate-like portion 15 will be described.
The plate-like portion 15r is formed of a steel plate that is thinner than the front and rear frames 60 and the left and right frames 62. A bent portion 15r1 is formed on the upper end side, which is excellent in strength and prevents a sharp edge from being exposed to the passage S side. An inclined plate 15r2 is formed which extends from the bent portion 15r1 and has a length approximately half of the height in the vertical direction of the rear frame 60r and is slightly inclined (preferably inclined by about 1 ° to 10 °) obliquely downward.

  A vertical plate 15r3 that extends from the inclined plate 15r2 and extends parallel to the intermediate plate 60r2 of the rear frame 60r, a horizontal plate 15r4 that extends from the vertical plate 15r3 and extends parallel to the lower plate 60r3 of the rear frame 60r, and rises upward from the horizontal plate 15r4. A raised portion 15r5 is formed opposite to the end of the lower plate 60r3 of the frame 60. An elliptical opening 15r6 is formed across the inclined plate 15r2 and the vertical plate 15r3 so as to project and expose the substantially conical limit switch 88r. Here, the right end of the intermediate plate 60r2 of the rear frame 60r is not covered by the safety bar 14r (FIG. 4), but is covered by the side cover 11 (FIG. 1), and the intermediate plate 60r2 is not substantially exposed. . The shape of the opening 15r6 is not limited, but if it is a circle or an ellipse, there is no portion where stress is concentrated and the strength is excellent.

  Thus, the vertical length of the safety bar 14r is substantially the same as the vertical length of the intermediate plate 60r2 of the rear frame 60r. Further, the length in the left-right direction is the same as the length of the portion of the intermediate plate 60r2 (the rear surface of the base 60) of the rear frame 60r that is not covered by the side cover 11, and the left-right direction of the intermediate plate 60r2. Is approximately the same size as The safety bar 14r is described as being formed of a thin steel plate, but the material is not particularly limited and may be other than metal.

(3-2) The swinging structure of the safety bar 14 will be described.
The base of the L-shaped hook 16 is fixed to the rear frame 60r side above the middle of the inclined portion 15r2 of the plate-like portion 15r by welding. The hook 16 has a notch 16a (oscillating shaft portion) formed in a plate portion that rises perpendicularly from the base portion. A base portion of an L-shaped metal fitting 70 (hook) is fixed to the inner surface of the upper plate 60r1 of the rear frame 60r by a screw 76. The L-shaped metal fitting 70 has a slit 72 formed in a plate portion extending downward from the base portion. The plate portion provided with the notch 16 a of the hook 16 is inserted into the slit 60 rs (insertion hole) of the rear frame 60 r and the slit 72 of the L-shaped metal fitting 70, and the notch 16 a is caught by the lower side portion 74 below the slit 70. .

  Since it did in this way, the safety bar 14r can be rock | fluctuated centering | focusing on the upper surface part of the notch 16a of the hook 16. FIG. Further, since the lower side portion 74 of the L-shaped metal fitting 70 is located in front of the rear frame 60 (on the right side in FIG. 5), the safety bar 14r is shaken even if an external force is applied to any part of the plate-like portion 15r. Can be moved. However, when the notch 16a is hooked in the slit 60rs of the rear frame 60, the safety bar 14r cannot be swung even if an external force is applied to the plate-like portion 15r above the notch 16a.

  Although it is possible to swing the safety bar 14r by providing a hinge at the upper end of the plate-like portion 15r, it is not preferable as compared with the first embodiment because the hinge is exposed to the outside. Further, when the hinge is provided inside the plate-like portion 15r, the upper end portion of the plate-like portion 15r becomes longer in the front-rear direction, and the upper end portion is more likely to be stepped on by a person. It is not preferable.

(3-3) The state when the safety bar 14 is not operated will be described.
In a state where no external force is applied to the safety bar 14r, the outer frame 60r and the vertical plate 15r3 are separated from each other by the height of the mount cone spring 84. Further, the safety bar 14r does not rattle because the upper end of the bent portion 15r1 (the restricting portion) is disposed so as to lightly contact the upper end of the intermediate plate 60r2 of the outer frame 60r. Further, since the upright portion 15r5 is provided opposite to the end portion of the lower plate 60r3 of the rear frame 60, even if an external force that moves the plate-like portion 15r rearward (in a direction away from the rear frame 60r) acts, 15r5 suppresses movement. In the state where no external force acts on the safety bar 14r, the upper end of the bent portion 15r1 is replaced with the intermediate plate 60r2 of the outer frame 60r instead of the upper end of the bent portion 15r1 contacting the intermediate plate 60r2 of the outer frame 60r. It is good also as the arrangement | positioning relationship which is spaced apart slightly from the upper part and the upper part 15r5 (regulation part) lightly contacts the edge part of the lower board 60r3 of the rear frame 60 lightly.

(3-4) The operation of the safety bar 14 will be described.
With reference to FIG. 8, the case where the vase 100 having a trapezoidal cross section has fallen in the passage S will be described. In this state, when the operator depresses the switch 12 of the movable shelf 5 and moves the right movable shelf 5 in the direction of the arrow A, first, the inclined plate 15r2 of the safety bar 14r comes into contact with the vase 100, and then the loaded plate is placed. When the plate-shaped portion 15r is rotated counterclockwise while compressing the head conical spring 84, and the amount of rotation reaches a predetermined amount (for example, the vertical plate 15r3 is displaced 5 mm toward the rear frame 60r), the position sensor 80 is activated, The moving shelf 5 is stopped. Therefore, even if it is the vase 100 with a trapezoidal cross section with the upper part bulging, it is not damaged.

  In addition, when the vase 100 is very light, after the inclined plate 15r2 of the safety bar 14r comes into contact with the vase 100, the vase 100 moves rearward (leftward in FIG. 8) together with the moving shelf 5, and then the left side. At least one of the safety bar 14f of the left moving shelf 5 and the safety bar 14r of the right moving shelf 5 is actuated to stop the moving shelf 5. When the safety bar 14 is activated, the movement of all the movable shelves 5 is stopped.

  With reference to FIG. 9, a case where a part of the article 102 placed on the lowest shelf 9 is hanging downward will be described. When the movable shelf 5 moves in the direction of arrow A, the movable plate 5 is sandwiched between the inclined plate 15r2, the vertical plate 15r3, the inclined plate 15f2 and the vertical plate 15r3 of the left movable shelf 5 (not shown), and the safety bar 14f of the left movable shelf 5 and At least one of the safety bars 14r of the right movable shelf 5 is activated, and the movable shelf 5 is stopped. Even when the article 102 'is hanging down to the inclined plate 15r2 portion, the movable shelf 5 can be stopped.

  An example in which an operator forgets an article 104 such as clothes in the passage S will be described with reference to FIG. When the movable shelf 5 moves in the direction of arrow A, the article 104 enters between the horizontal plate 15r4 and the floor 2, and when the movable shelf 5 moves further thereafter, the article 104 comes into contact with the horizontal portion 15r4 and resists against the horizontal portion 15r4. Act. This drag actuates the safety bar 14r and stops the movable shelf 5.

  A case where the U-shaped article 106 is hooked on the limit switch 88r protruding from the plate-like portion 15r will be described with reference to FIG. When the movable shelf 5 moves in the direction of arrow A, the article 106 is sandwiched between the inclined plate 15r2 and the vertical plate 15r3 and the inclined plate 15f2 and the vertical plate 15r3 of the left movable shelf 5 (not shown). At least one of the bar 14f and the safety bar 14r of the right moving shelf 5 is activated, and the moving shelf 5 is stopped. That is, before detecting that the limit switches 88f and 88r are equal to or less than the predetermined distance, the movable shelf 5 is stopped, and the article 106 can be prevented from being sandwiched and damaged by the base 6 that is a rigid body. Thus, by providing the opening 15r6 (FIG. 4), the plate-like portion 15r exists over the entire circumference of the limit switch 88r, so that a safety bar can be surely provided even if a person or an object exists near the limit switch 88r. 14r can be activated. At the same time, of course, the original function of the limit switch 88r can be realized.

  Although the example in which the opening 15r6 is provided for the limit switch 88r has been described with reference to FIG. 11, an opening for a stopper or sensor provided on the intermediate plate 60r2 of the rear frame 60r may be provided. FIG. 12 is provided with substantially rectangular parallelepiped stoppers 89f and 89r that alleviate the collision between the movable shelves 5 and 5. The shape of the stopper may be other shapes such as a cylinder other than a substantially rectangular parallelepiped. Openings 15f7 and 15r7 for projecting the stoppers 89f and 89r are provided in the plate-like portions 15f and 15r at positions facing the stoppers 89f and 89r.

  FIG. 13 is provided with ultrasonic sensors 90 f and 90 r for measuring the distance between the movable shelves 5 and 5. Based on the distances detected by the ultrasonic sensors 90f and 90r, the movable shelves 5 and 5 can be moved and stopped to an arbitrary position. Openings 15f8 and 15r8 through which the ultrasonic waves from the ultrasonic sensors 90f and 90r pass are provided in the plate-like portions 15f and 15r at positions facing the ultrasonic sensors 90f and 90r. Other sensors provided on the movable shelf 5 include an infrared sensor and a light receiving unit that constitute an obstacle detection unit that detects an object in the passage S.

  In short, for the functional parts provided on the intermediate plates 60f2 and 60r2 of the front and rear frames 60f and 60r, when the safety bars 14f and 14r impede their functions, the safety bars 14f and 14r may be provided with an opening. Parts are not limited to limit switches, stoppers, and sensors. The position where the opening is provided may be any of the upper side (FIG. 12), the center (FIG. 4), and the lower side (FIG. 13) of the safety bars 14f and 14r. Among these, if the center is selected, a large opening can be provided, and a large functional component can be employed.

(3-5) The protection of the safety bar 14r will be described.
As shown in FIG. 14, when the operator lowers the foot 110 downward in the direction of the arrow B, the safety bar 14 r is not stepped on the foot 110 and is not damaged, or the foot is not easily stepped on. It is preferable.

  Since the plate-like portion 15r is configured such that the bent portion 15r1 on the upper end side is in contact with the upper end of the rear frame 60, the foot 110 is not easily caught on the upper end side of the plate-like portion 15r. Furthermore, since the inclined plate 15r2 is connected to the bent portion 15r1, the foot 110 is not easily caught on the inclined plate 15r2. Further, since the vertical plate 15r3 is connected to the plate-like portion 15r2, the amount of the safety bar 14r that bulges in the front-rear direction is small, and the foot 110 is not easily caught. Furthermore, since the lowermost shelf 9 is located near the upper portion of the bent portion 15r1, even if the operator drops his foot near the movable shelf 5, the uppermost portion 9b hits the upper surface 9a of the lowermost shelf 9. There are many cases.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
