Description

    The present invention has a function of supporting the weight including the contents of the drawer when the drawer is pulled out from the cabinet (the cabinet housing the drawer is called a cabinet), and further restricting the movement so that the drawer does not fall off. Has drawer aids.

The drawer 1A is stored in the space for the drawer 1A provided in the cabinet 2B, but when the drawer is pulled out of the cabinet 2B to take out the items stored in the drawer 1A, a part of the drawer 1A is placed in the cabinet 2B. Otherwise, the drawer 1A is lowered forward by its weight, and a large force is applied to the mouth portion for inserting the drawer of the cabinet 2B. In the worst case, the mouth portion may be damaged. (See Figure 7)

If the drawer 1A is further pulled out, the drawer 1A will drop off, so in a general cabinet, depending on the weight of the drawer 1A and the length of the drawer, a part of the drawer 1A is left in the cabinet or cannot be pulled out more than necessary. Various stoppers are devised.

However, in the drawer 1A in which small objects and small stationery are put, small articles remain in a part of the hidden drawer 1A that cannot be pulled out. In particular, when the depth of the drawer 1A is shallow, it cannot be seen and cannot be taken out.

As countermeasures so far, a strong metal drawer mechanism and a mechanism that pulls out the drawer horizontally using rollers and bearings are used, but in these structures the roller and bearing take charge of the drawer and the drawer slides However, since these rollers and bearings are used, the structure is complicated and expensive. (For example, see literature patent application Hei 11-139760 and non-document European slide rail)

For this reason, in general cabinets endure the inconvenience, and most of them support the contents by restricting the person who pulls out the drawer size as usual.

The problem to be solved can be solved if the same technique is used to manufacture the drawer 1A and the drawer 1A is pulled out to the full depth by using an inexpensive material.

As an improvement measure, a drawer auxiliary tool 3C is provided on the side surface of the drawer 1A, and the drawer auxiliary tool 3C is limited in weight and drawer size.

Originally, the drawer 1A has a structure in which the weight of the contents is received by the plates on both sides of the drawer 1A. Therefore, the drawer auxiliary tool 3C can be produced using the material for manufacturing the drawer 1A.

The drawer auxiliary tool 3C has a sufficient length of the drawer auxiliary tool 3C so that it receives the weight of the drawer 1A when the drawer 1A is fully pulled out and does not apply excessive force to the drawer storage opening of the cabinet 2B. The drawer size of the drawer 1A is limited so that it remains in the drawer box and the drawer 1A is not pulled out and dropped out.

The drawer auxiliary tool 3C needs to be controlled so as not to leave the side of the drawer 1A in order to receive the load of the drawer 1A from the boss 11 provided in the drawer 1A and to limit the drawer size of the drawer 1A. This control is performed by grooves 23 and 24 provided in the cabinet 2B.

  Since the drawer auxiliary tool 3C of the present invention has a structure that can be provided with the original function of the drawer 1A as it is, the drawer 1A is hardly moved under the load of the drawer 1A when the drawer 1A is pulled out or inserted. Therefore, no roller or bearing is required for operation, the structure is simple, the same material as the material of the drawer 1A can be used, and the processing is the same in the process of manufacturing the cabinet 2B and the drawer 1A. Since the technology can be used, there is an advantage that it can be easily manufactured and is inexpensive.

However, even in this structure, when a heavy object is stored, it is possible to use a bearing or a roller for the sliding portion in order to make the movement light, but in this case, it becomes expensive.

Fig. 3 is a top view of the third stage drawer shown in Fig. 3 as viewed from the YY direction, showing the interrelationship between the cabinet 2B, the drawer auxiliary tools 3Cr, 3Cl, and the drawer 1A top surface. Yes. Fig. 4 is a cross-sectional view taken along the line ZZ in Fig. 4 and shows the arrangement of the cabinet 2B, the drawer auxiliary tools 3Cr, 3Cl, and the drawer 1A from the front, and the positional relationship between the respective sides can be understood. Indicates the relationship between the drawer 1A and the cabinet 2B when the drawer auxiliary tools 3Cr and 3Cl are not present, and indicates the forward drop when the drawer 1A is pulled out. 3 is a side view similar to FIG. 3, but FIG. 3 shows the drawer 1A pulled out to the maximum. In this figure, the drawer 1A is accommodated, and the boss 11 of the drawer 1A and the boss 21 of the cabinet 2B interfere with each other. And a gap t are shown.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In FIG. 1, 1A is a drawer, 2B is a cabinet for storing the drawer 1A, 3Cr and 3Cl in FIG. 4 are on the right and left of the drawer assistant, and the drawer assistants 3Cr and 3Cl are used to load the drawer 1A. At the same time as receiving, it is a limiting device that limits the size of the drawer 1A drawn out.

FIG. 1 is a three-dimensional perspective view of one embodiment of the mechanism of the present invention. Here, the right side of the drawer 1A as viewed from the front will be mainly described, but the left side is also symmetrical and the same.

Since the drawer 1A storage port of the cabinet 2B is made larger than the size of the drawer 1A so that the drawer 1A slides smoothly, the drawer 1A is in a state of being lowered forward as it is pulled out. See Fig. 6.

Although the degree of the front lowering differs depending on the structure, the position of the drawer 1A in FIG. 3 is the maximum of the drawer position, and when the drawer 1A is further pulled out, the drawer 1A is dropped. 31r, the cabinet boss 21 and the boss 32r of the drawer auxiliary tool are limited, and the drawer boss 11 transmits the load of the drawer 1A to the drawer auxiliary tool 3Cr.

The force that the weight of the drawer 1A acts on the drawer auxiliary tool 3Cr and the cabinet 2B will be described with reference to FIG. 3. When the drawer 1A is pulled out to the position of FIG. 3, the force generated by the weight of the drawer 1A is The wall 16 receives the surface 1p, and the weight of the drawer 1A is transferred to the drawer auxiliary tool 3Cr by the drawer boss 11.

The force transmitted to the drawer assisting tool 3Cr is received at the entrance 3p of the right groove 23 of the cabinet 2B, and the moment generated thereby corresponds to the upper surface 4p of the boss 32r at the rear end of the drawer assisting tool 3Cr. This is the same for the left side drawer extractor 32l.

The height h from the bottom surface to the top surface of 3Cr of the rear boss 32r of the drawer auxiliary tool 3Cr is a groove 23 provided in the cabinet 2B for sliding the drawer auxiliary tool 3Cr, and the upper part of the cabinet 2B in which the drawer 1A is stored. In between, it is made so that there is a gap that does not interfere with sliding of the drawer auxiliary tool 3Cr.

Furthermore, the height of the boss 11 provided on the drawer 1A from the bottom surface of the drawer 1A to the top surface of the boss 11 must have a margin t that does not interfere with the boss 21 provided on the cabinet 2B when the drawer 1A is completely stored. is there. (See Figures 3 and 7)

The size of the drawer auxiliary tool 3Cr pulled out from the cabinet 2B is such that the boss 11 of the drawer 1A is the front boss of the drawer auxiliary tool 3Cr from the position where the boss 21 of the cabinet 2B and the rear boss 32r of the drawer auxiliary tool 3Cr interfere. It is set at the position where 31r interferes, and it is considered that about half of the total length of the drawer auxiliary tool 3Cr is appropriate for the drawer drawer 3Cr to be pulled out, and about half of the drawer remains in the cabinet 2B. Is less than the drawer 1A.

The load received by the drawer auxiliary tool 3Cr from the drawer 1A boss 11 increases as the drawer size of the drawer 1A increases, and becomes the maximum load when the drawer 1A is limited to the maximum drawer length of FIG.

Drawer auxiliary tool 3Cr has bosses 31r and 32r at the front and rear, but boss 31r is made lower than boss 32r so as not to lift boss 11 of drawer 1A excessively when removing drawer 1A. It is sufficient if the movement of the boss 11 of the drawer 1A is high enough to be controlled by the drawer auxiliary tool 3Cr, and the depth and length of the recess between the bosses 31r and 32r of the drawer auxiliary tool 3Cr are also the boss of the drawer 1A. It is sufficient if 11 is in a range that does not hinder the movement of the drawer 1A without the limit size.

The groove 23 is a guide for the drawer assisting tool 3Cr and guides the drawer assisting tool 3Cr so as not to leave the side plate 13 of the drawer 1A.

The position of the drawer auxiliary tool 3Cr in the process in which the drawer 1A is pulled out or inserted is the sliding friction of the drawer 1A unless the boss 11 of the drawer 1A or the front plate 15 of the drawer 1A interferes with 31r of the drawer auxiliary tool 3Cr. Since it does not move except for, the position of the drawer auxiliary tool 3Cr is arbitrary.

The material of the drawer auxiliary tool 3Cr may be anything as long as it has a strength capable of withstanding the load including the contents of the drawer 1A, and any material that constitutes the drawer 1A is considered appropriate.

By adding a draw-out aid to the conventional draw-out function, the size of the drawer can be limited to the maximum and the weight can be shared, and the sliding-out load of the draw-out aid can be reduced by taking advantage of the conventional draw-out function. The material and technology for manufacturing the drawer auxiliary tool can be processed with the same material and technology as the cabinet and drawer, and has the advantage of being easy and inexpensive.
