Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a frame for storing articles installed in an upper position (including a single shelf board, a hanging shelf, a hanging storage box, etc.); This invention relates to a device for taking out furniture, etc., which pulls down a piece of furniture (also referred to as furniture, etc.) and allows articles stored in a frame to be easily taken out from a lower position.

In a conventional furniture mounting device, a frame body for storing articles is attached to the upper end of an arm whose lower end is pivoted to a base frame, and the frame body is pulled downward toward you using the lower end of the arm as a pivot point. Such a device has a drawback that the forward protrusion is large and therefore difficult to install if there is no free space.

Therefore, the present invention has been made to eliminate the above-mentioned drawbacks, and provides a device for taking out furniture, etc., which can reduce the size of taking it out to the front and can be used even when there is not a large space. This is what I am trying to do.

The drawings showing the embodiments of the present application will be described below. 1 indicates a fixed object to which this device is attached. Examples of this fixed object include a shelf board provided at the top of the room or a top plate of a cupboard. Next, in the take-out device, reference numeral 2 denotes a base frame, which is attached to a mounting piece 3 fixed to the fixed object 1 with fixing bolts 4 and nuts 4a using fasteners 2' (for example, screws). 5 indicates a frame for storing articles. There are various types of this frame as mentioned above, but
This example shows the case of a box. Reference numeral 6 denotes a frame body, which is formed into a box shape with an open top. Reference numeral 7 indicates a connecting frame fixed to the upper end of the main body 6, and 8 indicates a pull-down handle attached to the front lower part of the main body. Reference numerals 9 and 10 indicate long holes formed in the base frame 2, which are long in the front and rear, respectively, as shown in FIG. In this specification, the right side in FIG. 3, that is, the side where the operator is located, is referred to as the front, and the left side in FIG. 3 is referred to as the rear. 11 and 12 are arms each having the same length and arranged in parallel;
The lower end of each is connected to the long hole 9 using connecting bodies 13 and 14.
10, and their lower ends are also connected by a connecting piece 15. Further, the upper end of each arm is pivotally connected to the connecting frame 7 using a shaft 16, respectively.

Next, the above-mentioned connecting body 13 will be explained. Reference numeral 17 denotes a movable body inserted into the elongated hole 9, which is formed in an annular shape. Reference numeral 17a indicates the shaft portion thereof, and reference numeral 17b indicates the collar portion. 18 is a washer, 19 is a shaft body, which is inserted through the through hole 20 provided at the lower end of the arm 11, one end of the connecting piece 15, the movable body 17, and the washer 18, and has a large diameter shaft provided at both ends thereof. Retaining part 19a,
19b connects each of the above-mentioned members so that they do not separate from each other and allows the arm 11 to tilt and the movable body 17 to rotate. Since the connecting body 14 has substantially the same structure as the aforementioned connecting body 13 (except that the shaft portion 17a is formed short), a detailed explanation thereof will be omitted.

Next, 23 indicates a movement limiting mechanism attached to the lower end of the arm 11. In this mechanism, reference numeral 24 is easily attached to the lower surface of a fastening piece 25 that is fastened to the base frame 2 by a fastening threaded rod 26. 27
is a gear formed in a fan shape, and the shaft portion 17a of the movable body 17 is inserted into the shaft hole 28 of the shaft portion 17a.
The gear 27 is positioned so that it can freely rotate relative to the gear 27. Also, the teeth of this gear 27 are connected to the rack 2.
4 is interlocked. Reference numeral 30 designates an interlocking hole formed in the gear 27, which is formed in an arc shape centered on the shaft hole 28. Reference numeral 31 denotes an interlocking piece fixed to the arm 11, the tip of which is located within the interlocking hole 30.

Next, 41 indicates a biasing mechanism. In this mechanism, reference numeral 42 denotes a support, which includes a seat 43 attached to the base frame 2, and a shaft (threaded rod) 4 protruding from its tip.
4. A nut 45 screwed onto the shaft body. 46 is a lever, the middle part of which is connected to the shaft body 44.
It is pivotally connected to and is prevented from coming off by a nut 45. 47 indicates a long hole. Reference numeral 48 denotes a biasing device, which consists of a main body 49 whose one end is attached to the base frame 2 and an advancing/retracting rod 50 protruding from the main body 49;
Moreover, the advancing/retracting rod 50 is always biased in the direction of extension from the main body 49 (by a spring inside the main body 49), and is configured to move slowly in that direction (using a well-known shock absorber). similar configuration). Further, the advancing/retracting rod 50 is configured to move quickly in the direction of recessing into the main body 49 (movement in the direction of resisting the biasing force). Reference numeral 51 denotes a connecting member that connects one piece of the lever 46 and the tip of the retractable rod 50, and is configured so that its position can be changed within the range of a long hole 52 provided in the lever 46. This makes it possible to adjust the magnitude of the biasing force (clockwise in FIG. 5) that the biasing device 48 applies to the lever 46. Reference numeral 35 denotes a connecting member for connecting the lever 46 and the arm 11, one end of which passes through the elongated hole 47 and the other end fixed to the arm 11. In this connecting member 35, 36 is a cylinder;
37 and 38 are washers, 39 is the arm 11 and the cylinder 3
6. Each member is fixed to the arm 11 by a pin inserted through washers 37 and 38, and by tightening portions 39a and 39b at both ends of the pin. In addition, the long hole 47
The length is such that the connecting member 35 attached to the arm 11 can move within the elongated hole 47 over the entire range in which the arm 11 moves as described below. Reference numeral 34 denotes a through hole drilled in the base frame 2, through which the connecting member 35 passes. The size of this hole 35 is set so as not to hinder the movement of the linking member 35 over the entire range of movement of the arm 11 as will be described later.

The arms 11 and 12, the movement limiting mechanism 23, the biasing mechanism 41, and the like are respectively provided on the base frame 2 on the left side and the base frame 2 on the right side with the frame body 5 as the center. In Figures 3 to 6, the one installed on the right side is shown, but the one installed on the left side is just the right and left side when viewed from the direction of Figure 2. Since the configurations are exactly the same, detailed explanation thereof will be omitted. Reference numeral 53 denotes a cover that covers the biasing mechanism 41 and is attached to the base frame 2.

In the case of the above structure, when pulling down the frame 5 toward the user, the user hooks his/her hand onto the handle 8 and pulls the handle 8 toward the user. Then, in the first half of the movement of the frame 5, the arms 11 and 12 tilt forward about the connecting bodies 13 and 14, as shown in FIGS. 7 and 8. In this case, the interlocking piece 31 moves along the interlocking hole 30 to the point where it abuts the front edge 30a thereof. Due to this movement, the frame body 5
moves almost horizontally forward. in this case,
The clearance between the through hole 20 at the lower end of the arm 11 and the shaft body 19 and the clearance between the interlocking hole 30 and the interlocking piece 31 are sufficiently large, so that the resistance at these points is extremely small. On the other hand, gear 27 has a large resistance to rotation due to its meshing with rack 24. As a result, the gear 27 does not rotate during the above process, and therefore the lower end of the arm 11 does not move rearward along the elongated hole 9. Next, in the second half, handle 8
When the arms 11 and 12 are pulled forward and downward, the arms 11 and 12 tilt further forward, but in this case, the interlocking piece 31
Since the gear 27 is in contact with the front edge 30a, the gear 27 is forcibly rotated by the arm 11. Therefore, the connecting body 13 moves rearward along the elongated hole 9. Further, the connecting body 14 connected by the connecting piece 15 similarly moves rearward along the elongated hole 10. Arm 1
In the process in which 1 and 12 tilt forward as described above, the connecting bodies 13 and 14 move rearward in this way, so that the frame 5 does not move forward much from the position shown in FIG. 8, but mainly points downward. and move
The device is brought out as shown in FIG. 9.

Next, when storing the frame 5 in its original position, the frame 5 is pushed upward from the state shown in FIG. At this time, the biasing force of the biasing mechanism 41 is applied to the arm 1.
Since it works in the direction of pushing up 1, the pushing up can be done with a light force. In the first half of this push-up process, the connecting bodies 13 and 14 remain located at the rear ends of the respective elongated holes 9 and 10, and the arms 11 and
12 returns upwardly around the connecting bodies 13 and 14, and the interlocking piece 31 engages the interlocking hole 3.
0 until it abuts the trailing edge 30b. Next, in the second half, since the interlocking piece 31 is in contact with the rear edge 30b of the interlocking hole 30, the gear 27 is forcibly rotated by the upward return rotation of the arm 11.
counterclockwise rotation in the figure). Therefore, the connecting body 13 located at the axis of the gear 27 moves forward along the elongated hole 9, and when the frame 5 returns to its original position (the position shown in FIG. 7), the connecting body 13 moves forward. It returns to the front end of the elongated hole 9. In this case, as a matter of course, the connecting body 14 also returns to the front end of the elongated hole 10.

To explain the above movement with reference to the locus diagram in FIG.
a moves through a trajectory shown by 62a, and in the latter half section 61b, the upper rear end 5a descends through a trajectory shown by 62b.
In addition, in the above process, the lower rear end 5b of the frame 5
move through trajectories indicated by 62a' and 62b', respectively.

On the other hand, in the process of storing the frame, that is, in the process of moving upward, the upper rear end 5a moves along a trajectory indicated by 62c in the first half, and passes through a trajectory indicated by 62d in the second half. Move along. Further, in this case, the lower rear end 5b returns to its original position through the loci indicated by 62c' and 62d', respectively.

In addition, when the above-mentioned movement is performed, the hole edges 34a, 34b, 34c, 34d of the through hole 34
are the first half, the second half, and the second half of the forward tilting rotation of arm 11, respectively.
Since it is formed so as to surround the outside of the connecting member 35 along the locus of movement of the connecting member 35 in the first half and the second half of the return rotation of the arm 11, each hole edge does not affect the movement of the arm 11. There isn't.

Next, FIG. 11 shows an example in which the object to which the take-out device is attached is different, and shows an example in which the base frame is attached to a wall plate 64. Examples of the wall plate 64 include the upper part of a wall of a building, or the upper part of a rear wall inside a chest of drawers, a closet, and the like.

Next, various other aspects of the above structure are shown. In order to make the lower end of the arm movable back and forth, instead of the elongated holes 9 and 10 and the movable bodies 13 and 14, the following structure is used. may also be used. That is,
In the base frame 2 in the front-rear direction (same direction as the long holes 9 and 10)
Two rails are attached to each rail, and each piece is equipped with a piece to move back and forth along each rail, and each piece is made to be able to tilt the lower end of each arm in the same direction as above. It may be pivoted.

Further, as the movement restriction mechanism, the following configuration may be used instead of the above configuration. That is,
A guide piece is attached to the intermediate part of the arm 11, while a guide groove is formed in the base frame 2, and the guide piece is left in the guide groove.
In the process of tilting, the guide piece is moved along the guide groove, and the shape of the guide groove is changed to the holes edges 34a, 34b, 34c,
By forming the arm 11 into a shape similar to (similar to) 34d, the arm 11 can be caused to move along a trajectory similar to that described above.

As described above, in the present invention, the base frame 2 includes two arms 1 arranged parallel to each other.
The lower ends of each of the two arms 11 and 12 are connected in a tiltable manner, and the upper ends of each of the two arms 11 and 12 are pivotally connected to the article storage frame 5 disposed above the base frame. By tilting the arms 11 and 12 forward, the frame body 5 can be moved downwardly in front of the base frame 2 in a curved trajectory with the lower ends of the arms as pivot points. Therefore, (a) Even if the frame 5 is placed in a high place that is out of reach, when taking out an article from there, the frame 5 must be moved to a low place and stored there. This has the effect of allowing the stored items to be handled from a low position and making it easier to take out the items.

Moreover, in this invention, in addition to the above configuration, the lower ends of the arms 11 and 12 are connected to the base frame 2 by connecting the lower ends of each arm movably toward the rear with respect to the base frame. In the arm, the rearward movement of the lower end of the arm is restricted in the first half section 61a of the forward tilting of the arm, and the rearward movement of the lower end of the arm is allowed in the latter half section 61b. Since the movement restriction mechanism 23 is attached, it has the effect of (a) above, and (b) in the first half of the movement of the frame 5 as described above, the pivot point of the arm is moved to the forward position. It has the advantage that the frame body 5 can be largely moved substantially horizontally forward while the frame body 5 is held in place. This has a great effect in that even if the frame body 5 has a large depth, it can be taken out as described above.

(c) Moreover, even if the arm is used to descend as described above using its lower end as a pivot point, in the process of descending following the first half, the descending trajectory of the frame 5 will be the same as the original. It is not a trajectory (a trajectory in which the frame 5 descends while the pivot point of the arm remains in the front), but a trajectory that descends backwards from that point, and therefore the frame 5 in the above process
It has the advantage that the forward protrusion dimension can be reduced. This has the practical effect that it can be used not only in places with a large open space in front, but also in narrow places.
