[Conventional technology]

Conventionally, guide rails are provided on one of the inner surfaces of both side panels of furniture, etc. and the outer surfaces of both side panels of a drawer, rollers or sliders are provided on the other side, and stoppers are formed at appropriate positions on the guide rails. Various types of drawer sliding devices are available. For example, 1978 Utility Model Application Publication No. 43948
As disclosed in No. 1, a front-rear track is provided on each inner side of both sides of the main body of a furniture, etc., and the rail is slidably fitted into a groove provided on each outer side of both sides of a drawer. and a slider provided at the rear part of the groove can be brought into contact with a stepped part formed at the front part of the rail,
For this type of track or guide rail, its depth is usually set longer than the depth of the drawer, so it is difficult to draw out furniture, etc. whose depth is larger than the length of the track or guide rail. It cannot be applied to the drawer, and the length must be made according to the depth and width of each drawer, and it cannot be manufactured to the same standard for the purpose of reducing costs through mass production. The rear end of the guide rail is located deep inside the furniture drawer storage space, so
The problem was that the installation work of the rails or guide rails, sliders, rollers, etc. was extremely difficult.

[Problem that the invention attempts to solve]

In view of the above-mentioned situation, the present invention aims to solve the problem by having a simple structure, a small number of parts, and being able to be installed extremely easily on the inner surface of both side panels of furniture, etc., and with the same standard rails, the depth dimension can be reduced. It is an object of the present invention to provide a drawer slide device that can be applied to various types of different drawers, can prevent the drawer from coming off when normally pulled forward, and can easily remove the drawer.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention creates an upper sliding surface on the front end of each inner surface near the front of both sides of furniture, etc., and continues downward from the rear end of the sliding surface. A stepped portion is formed with an abutment surface, and an upper surface rearward from the stepped portion is formed approximately parallel to the sliding surface, and a downward slope is formed from the front edge of the lower surface to the rear portion, and a downward slope is formed after the slope. A rail is attached with the lower surface at the rear from the end serving as a lower sliding surface substantially parallel to the upper surface, and the rail is slidably fitted into a groove in the front and rear direction formed on the outer surface of both side plates when pulled out. , a protrusion is formed above the rear end of the concave groove to abut against the stepped portion of the rail and can slidably abut on the upper surface of the rail; A slide device for the drawer was constructed by attaching rollers or sliders to each inner surface of the side plates to support and guide the lower edges of the side plates of the rail.

[Effect]

The drawer sliding device of the present invention, which has the above-mentioned contents, is equipped with a rail shorter than the depth of the drawer in the front-rear direction on each inner surface near the front of both side panels of furniture, etc., and at a position rearward from the rear end of the rail. A roller or a slider capable of supporting and guiding the lower edges of both sides of the drawer is attached to the drawer, and the rail is positioned in the groove in the front and rear direction formed on the outer surface of the both sides of the drawer. A stepped portion having a sliding surface in contact with the upper edge of the inside of the concave groove, the lower edges of both side plates of the drawer being supported on the roller or slider so as to be slidable, and having an abutting surface formed on the upper part of the rail. The protrusion formed above the rear end in the concave groove of the drawer is abutted to prevent the drawer from coming out, and the drawer is pulled forward so that the rear ends of the lower edges of both side plates are aligned with the rollers or sliders. The protrusion is slidably brought into contact with the upper surface behind the step of the rail to prevent the rear part of the drawer from falling when the drawer passes through the rail, or the lower part of the front part of the drawer is prevented by moving the center of gravity of the drawer forward. Tilting is prevented by the lower edge inside the groove coming into contact with the lower sliding surface, and when the drawer is pulled out to the maximum extent, the front part of the drawer is lifted upward and the lower edge inside the groove at the rear end of the drawer is prevented from tilting. The edge is made substantially parallel to the slope of the rail so that the engagement between the stepped portion and the protrusion can be released to allow the drawer to be removed forward.

〔Example〕

Next, the present invention will be further explained in detail based on the embodiments shown in the accompanying drawings.

Figures 1 and 2 show typical embodiments of the present invention, in which 1 is furniture such as a desk or chest of drawers, 2 is a drawer that can be slid out and is attached to the furniture 1, and 3 is the drawer. A rail for slidingly guiding the drawer 2 in the front and rear directions, and 4 a roller or a slider that can support and guide the drawer 2, respectively.

The drawer 2 is a normal type having side plates 5, 5 on both sides, and grooves 6, 6 having a substantially U-shaped cross section are formed in the front and back direction on the outer surfaces of the side plates 5, 5. The front end of 6 is closed at the back of front plate 7, but the rear end is open. As shown in FIGS. 1 and 3, the rail 3 has a vertical width that can be slidably fitted into the groove 6 of the drawer 2, and is set shorter than the length of the groove 6. It is integrally formed of synthetic resin with good sliding properties, and has an upper sliding surface 8 that can come into contact with the upper edge of the groove 6 at the front end of the upper surface.
A stepped portion 9 having a continuous stop surface downward from the rear end of the upper sliding surface 8 is formed, and an upper surface 10 extending rearward from the stepped portion 9 is substantially parallel to the upper sliding surface 8. A notch 11 is formed in the lower surface, and a downward slope 12 is formed from the front edge of the lower surface to the rear, and the lower surface of the rear end from the top 13 of the rear end of the slope 12 is connected to the upper sliding surface 8 and the upper surface 10. The lower sliding surfaces 14 are formed substantially parallel to each other, and mounting holes 15 are formed in the front and rear sides. Here, in this embodiment, the rail 3 is made of synthetic resin, but of course it can also be made of metal or wood.

The rail 3 has the mounting holes 15,
It is attached with a screw (not shown) inserted through the hole 15, and is slidably fitted into the grooves 6, 6 of the drawer 2, but it is used to prevent the drawer 2 from coming off when it is pulled out forward, and to prevent the rear part of the drawer 2 from tilting downward. Protrusions 17, 17 designed for prevention are fixed above the rear end portions within the grooves 6, 6 of the side plates 5, 5 of the drawer 2, respectively. The protrusion 17 has a downward protrusion height that substantially matches the height of the step 9, that is, a gap formed between the upper edge of the groove 6 and the upper surface 10 of the rail 3. It is set slightly lower than
If it is made of a synthetic resin with good sliding properties like the rail 3, the drawer 2 can be supported and guided smoothly.

Further, the roller 4 supports the drawer 2 in a slidable manner with an upper sliding surface 8 that abuts the upper edge in the groove 6 of the drawer 2, and each of the side plates 5, 5 of the drawer 2 It is rotatably attached to the inner surfaces of the side plates 16, 16 of the furniture 1 at vertical height positions that can support the lower edges 18, 18. The installation position of the roller 4 in the depth direction is more stable if it is set as far back as possible considering the center of gravity of the drawer 2, but it is more stable if the roller 4 is installed as far back as possible. In order to support the drawer 2 and to allow it to be pulled out as far forward as possible,
It is necessary to install it at a position where the distance l from the rear end of the rail 3 to the axis of the roller 4 is shorter than the distance L from the rear end to the front end of the protrusion 17.
Note that the roller 4 is attached to the lower edge 18, 1 of the drawer 2.
8 can be supported in a slidable manner, other structures can be used instead. For example, sliders of circular, oval, and various shapes can also be used.

When the rails 3, 3 are fitted into the grooves 6, 6 of the drawer 2, as shown in FIG. The lower edge 18 of the drawer 2 is slidably supported on the upper edge in the groove 6 and is supported by the roller 4 on the lower edge 18 of the drawer 2.
18 is smoothly supported, and when the drawer 2 is housed, the tip of the rail 3 comes into contact with the back surface of the front plate 7, and the backward movement of the drawer 2 is restricted. When the drawer 2 is pulled out from this stored state, as shown in FIG. When the drawer 2 reaches the position of the upper surface 10 from the roller 4 and is further pulled out, the lower edge 18 of the drawer 2 comes off from the upper surface of the roller 4, and then the protrusion 17
comes into contact with the upper surface 10 of the rail 3, or when the center of gravity of the drawer 2 moves forward from the front end of the upper sliding surface 8, the lower edge in the groove 6 touches the lower sliding surface of the rail 3. In contact with the surface 14, the drawer 2
While maintaining the horizontal state, the rail 3 can be stably pulled out until the protrusion 17 comes into contact with the step 9 of the rail 3, as shown in FIG. In addition, when removing the drawer 2, as shown in FIG. Using the rear end of the upper edge as a fulcrum, the protrusion 17 rotates upward and rises, and the engagement between the protrusion 17 and the stepped portion 9 of the rail 3 is released, and in this state, the drawer 2 is If you pull it out diagonally upward as indicated by the middle arrow, the protrusion 1
7 moves above the stepped portion 9, and the drawer 2 can be removed from the furniture 1 very easily. If the above operation is performed in reverse, the drawer 2 can be slidably attached to furniture very easily.
