The eighth-grade rails in this case are generally referred to as pull-outs, including drawers, pull-out tables, and so on. [Prior art] Since the prior art, such as the drawer of a cabinet, especially in the case of pulling out a heavy object ’In order to smoothly pull it out, it is equipped with individual rollers to make single or multiple rails. It is disclosed in the following patent reading i. A slide rail, which replaces individual rollers, and incorporates a unit member formed by mounting a plurality of rollers (including disc-shaped members) on a holder. (Patent Document 1) Japanese Patent No. 3354637. [Summary of the Invention] Increasing the size of the drawer with respect to the frame size of the drawer storage body as much as possible is a natural issue considering the miniaturization of furniture. However, within the scope of the above-mentioned publication, it can provide smoothness to prevent horizontal and vertical shake. There is room for improvement in the technology of moving the slide rails to achieve this miniaturization. In addition, since the holding member has a predetermined gap when the inner rail is installed on the drawer side, if it is installed on the drawer side and pulled out, there may be cases where the assembly mounted on the inside can be seen from the outside, and the appearance is damaged. In addition, since it is a sliding member, for example, lubricating oil also adheres, which may stain hands or clothes. 1231190 Therefore, an object of the present invention is to provide a single-type guide rail which can operate smoothly and reduce the width of the guide rail and can be miniaturized. Another object is to prevent the user from being contaminated while maintaining the aesthetic appearance when the pull-out body is pulled out. In view of the above purpose, the scope of patent application is the first! The item provides a "single-type guide, which has: a rail member provided on the side of the pull-out body (20) of furniture such as a cabinet, and a relative movement relationship with the rail member provided on the side of the storage body (10)" The holding member is characterized in that the holding member (22) is provided with a second wall portion (22B) extending from one end of the first wall portion k 'in a cross-sectional view. The other end portion, the fourth wall portion (⑽) which extends in a same direction as the second wall portion, and extends from the front side of the second wall portion; A third wall portion (22c) separated from the fourth wall portion; 'Another / member (12) is provided with a wall portion in a cross-sectional view (system, from the side of the third wall portion toward the second wall) B wall portion (12 B) 'is extended from the leaning into the Chu portion; C wall portion (:) "the end portion of the A wall portion toward the end of the second wall toward the second ... The 2nd wall portion of the 8th wall portion IA Shirts soil # extension; and the extension portions (12D, 12E) are connected to the 1M mesh and extend to the outside of the rail member ；; the holding member (22) is separately — &Amp; ^ On, with: The hibiscus member (12) has a gap (22) from each other, and can be used for this— (30), which has a cross-sectional shape inserted in the rail member; and the B wall portion and G of the safety member (12) The first rotating body (Rl) which is inserted between the wall portion and the female member and is broken between the i-th wall portion and the facing wall surface of the 1231190 B wall portion, and the third wall portion and the B wall portion. The second rotating body that rotates between the wall surfaces is a third rotating body that rotates between the opposing wall surfaces of the fourth wall portion and the c wall portion (=, and approximately the opposing wall surfaces of the second wall portion and the fourth wall portion). 4 rotating bodies (R4) between rotations. One rail member and the other-actuating member are not limited to _ each. In the case of a plurality of roots, 'increasing the rotating body (holding member with the rotating body installed), dispersing the load' has an improved guide rail The effect of durability. Since a rotating body that rotates between each inner wall surface of one of the rail members and the wall portions of A, B, and C of the other rail member is provided, the on-rail member and the other When a rail member moves relative to each other, the movement that forms rolling friction is' moved with a small force 'and' rotates through each other The body is restrained in the two-dimensional direction, so it can suppress shaking and smooth operation. What's more important is that the third rotating body and the fourth rotating body are respectively extended by the length of the B wall portion (width ) The c-wall section and the a-wall section that are separated from each other ^ Replace the rotating bodies with each other along the width direction according to the width of the B-wall section 'because &' One rail member can be miniaturized, and the guide rail can be miniaturized. The second scope of the patent application provides a single-type guide rail such as the scope of the patent application 项 J. Among them, the rail member (22) is installed on the pull-out body (20) side, and the other rail member (12) is installed on the storage body. (10) side, and further includes a plate-like member (28), which is attached to the pull-out body side and is arranged so as to substantially cover the rail member (22) from the outside. A gap opening exists in one rail member due to the necessity of relative movement between the third wall portion and the fourth wall portion. Therefore, the rail member is attached to the pull-out body 1231190.

On the right, the holding member of the necessary member is used to sharply increase the resistance of the pull-out body and the resistance of the pull-out body, and the pull-out body can also be temporarily stopped, and the mechanism is also very [Embodiment] The following embodiment is shown in the drawings The present invention will be described in more detail. FIG. 1 is a side view of a single-type guide of the present invention, and FIG. 2 is an enlarged cross-sectional view of an arrow | line BB. However, the unit body described later in FIG. 2 is a plain plane. To clearly show the pattern of the roller. When a cabinet is taken as an example of furniture, the drawer 20 of the pull-out body is horizontally guided to and from the frame body 10 of the storage body, and the guide mechanism is guided in the horizontal direction. However, even if it is guided in a direction other than the horizontal direction, such as the up-down direction, it is still within the scope of this case. The guide mechanism will be described mainly with reference to FIG. 2. A holding member 1231190 22 is a drawer-side holding member that is mounted on the drawer 20 in this example. Although it is, for example, a bracket 20B provided on the side 20H of the drawer is engaged with a flat plate provided on the left and right (direction) of the drawer side rail member 22 The engagement j 卩 22F of the wall-shaped wall portion 22A (the first portion) (hereinafter, the flat shape is omitted for each wall portion) is attached to the drawer, but it may be directly attached to the side wall of the drawer. Up and down (direction) wall portions 22D (fourth wall portion) and 22B (second wall portion) extend at right angles to the left and right end portions of the left and right side walls, respectively, at the upper and lower wall portions 22b on the drawer side 20H side. It stands on the same side as the wall part 22A at about 50 meters, and the left and right (direction) wall parts 22C (brother 3 wall parts) extend in a curved shape in parallel. The extension width of the left and right wall portions 22C is smaller than that of the left and right wall portions 22A, and the extension width of the upper and lower wall portions 22D is smaller than that of the upper and lower wall portions 22B. Therefore, a gap opening exists between the left and right wall portions 22C and the upper and lower niche 22D. In order to ensure a gap opening, if either one of the left and right wall portions 22C and the upper and lower niche 22]) has a small width, the other may be the same as or longer than the wall portion 22A or 22B. Furthermore, 'In this example, although the wall portions of the drawer side rail structure # 2 2 extend at a right angle f curved shape', the angle between these wall portions in this case is not limited to a right angle. general

Returning to the example of FIG. 2 again, in this example, another rail member 12 is attached to the frame side rail member 'of the frame body 10', although it will be provided, for example, in an extension portion of the frame side rail member 12 described later. The upper and lower "12 £ engaging portions ι2β are engaged with the frame body 10 for installation. However, the upper and lower wall portions 12E may be directly connected to the frame body. The upper and lower wall portions 22C extend vertically near the ends of the left and right wall portions 22C and extend upward. The upper and lower niches 12A are formed, and the curved water 1231190 extends in the direction of the wall part 平 to extend the upper end portion thereof to form the left and right wall parts 12β, and is further curved in a position near the wall part and extends toward the wall part 22A. The upper and lower wall portions 12C are separated from the wall portions 22A. On the other hand, the lower end portion of the wall portion 12A is located near the height position of the wall portion 22c, preferably at a position lower than the same wall portion 22C, and extends horizontally in a curved shape in the direction of the frame body to form left and right walls. Part (the first extension part) Shan ^ extends its end part in a curved shape in the vertical upward direction to form an upper and lower wall part (the second extension part) 12E. It can also extend in the vertical downward direction. As the above frame side rail member 12 It is separated from the drawer side rail member 22. There is no abutment | part. In order to maintain this separation state, 'the unit shown in Figure 3 is inserted into the drawer side holding member. The main body of the above unit body, namely The cross-sectional shape of the holding member 30 is a cross-sectional shape into which the wall portions 12β, 12 (: of the frame-side rail member 12 can be inserted, and can be inserted into the frame-side rail member. This cross-sectional shape is shown in FIG. 2 The rollers R1, R2, R3, and r4, which are arranged at four positions as rotating bodies, are mounted on the holding member. That is, in the second figure, the upper roller R1 uses the horizontal axis ci as the axis rotation #, and the lower The roller R2 rotates around the horizontal axis C2, and the upper roller R3 rotates The straight axis C3 rotates around the axis, and the lower roller R4 rotates around the vertical axis C4. The roller R1 has a size approximately between the wall portions 12B and 22A, and the roller R2 has a size approximately between the wall portions 12B and 22C. Therefore, the vertical movement of the drawer side rail member and the frame side rail member can be prevented. Also, the roller R3 has a size approximately between the wall portions 12C and 22]), and the roller r4 has approximately The size between the wall portions 12A and 22B. Therefore, it is possible to prevent the left and right sides of the drawer 1231190 side rail member and the frame side rail member from shaking. Two rollers R2 are installed on the front and rear, one roller R3 is installed on the front and back, one is installed on the front and rear sides of the roller R4, but only four can be installed on the front and back, or one can be installed on each of the four. The inner dimension of the side rail member 22 in the up-and-down direction must be the sum of the diameters of the rollers R1 and R2 and the thickness of the wall portion 12B. However, the inner dimensions of the left-right direction may be larger than the diameters of the rollers R3 and R4. The size and the thickness of the wall part 12C (or 12A) are small. The width of the drawer side rail member 22 can be reduced in the storage space for drawer storage provided inside the frame 10, and the internal size of the drawer in the left-right direction can be further increased as much as possible. Also, the drawer side rail is pulled out to the right The member 22 may see the unit body inserted into it from the gap openings of the wall portions 2 2 C and 22D. In addition, the dirt of the holding member 22 may be stained by the user. Therefore, if it is installed in a drawer, For example, under the shape of 'h', a wall portion 28 (a plate-shaped member) indicated by a two-point chain line extending to the frame body side of the wall portion 22D slightly below the wall portion 22D can conceal the above-mentioned unit body. The user is prevented from contacting the drawer-side holding member 22. Preferably, the lower end of the wall portion 28 extends to the vicinity of the horizontal position of the wall portion 22C. Although the wall portions of the drawer-side rail member 22 extend in a right-angled bend in the example of the embodiment described above, the angle between these wall portions is not limited to a right angle. Although each wall portion of the frame-side rail member 12 extends in a right-angled bend, the angle between these wall portions is not limited to a right angle. 11 1231190 Furthermore, 'may not be on the side of the drawer but on the linen member 22'. That is, if the person is to install drawer side rails 9: bottom to face on the right ... Considering the surface 20H in FIG. 2 as the bottom surface, the height dimension of the rail member 22-the depth dimension of the pumping unit 1 in this case. In this case, even for example, the width can be increased near the central position, because the left and right portions I of the drawer can still be equipped with: two: the installation position without the problems of the safety of the wall portion 28 and the pollution prevention . In addition, the position of the women's clothing on the wall 8 can be the side of the drawer or the bottom. It is also possible to change the two rail members 22 and the drawer suction frame. The individual installation objects are drawn on the 'drawer side and one in the above example, but this case is not limited to this. Although the rail members on the side are each provided, Fig. 4 is a side view of the main part that pulls the drawer out to the front. The drawer and the early-type guide rails on the side of the frame ^ hh ^ m ^ and then move together after 1,22, the inner ^ early · It moves at half the speed of the rail member: rollers, so each moving member can be flat, exist In the case of drawers, Ιέ i-μ Di Er rubs and moves. In the pull-out #drawer below, the retaining member of the early mortal body is provided at the stop portion uj of the rail member 12 (P 30F abuts. Brother engagement portion), so that the unit body cannot be stopped. The fish moves forward by the rolling friction between the unit body and the rollers, and the unit body will not advance smoothly in the stopped state. It may fall down and stay in the stomach for ^ month b. It will be issued as shown in Figure 1. Privately, "This situation stops." The 22HS block sighs the forward τ stopper 22HS near the rear end of the member 22 and abuts the holding member 3 to approximately ^^ 30, which is approximately the holding member 30 of the unit body. That is, the end portion of the arranging member abuts vertically on the stopper 12FS of the rail structure 12 1231190, and the stopper 12FS is identical to the stopper 12FS, and the stopper body 22HS abuts the rear end portion 30R of the holding member. In the shape of the storage pump Jf, the rear end portion of the holding member 30 abuts on the brain of the stopper portion (second engagement 1) provided at an appropriate position of the rail member ^, and stops the early body. However, 'if advance-step The drawer is strongly pushed, although the drawer and the rail member 22 do not retreat by the rolling friction between the unit body and each roller, the unit body It will keep the stop state to retreat smoothly, and it will fall when there is space in the rear. To prevent this situation, as shown in FIG. 1, the back stop body 22SS arranged at an appropriate position of the rail member 22 abuts the front end of the holding member 30. That is, while the rear end portion of the holding member 30 abuts the V stop portion 12RS provided on the rail member 12 and the green body stops, the rear end stop body 22SS of the rail member abuts the front end portion of the holding member. As mentioned above, this case can be applied to tables, etc. in addition to drawers. Although there are duplicated parts, the items described in the different forms can be applied to other forms as long as there is no particular contradiction. It can be seen from the above description that according to the present invention, a single-type guide rail capable of providing smooth operation and reducing the width of the guide rail can be provided.
