Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding guide mechanism for facilitating the movement of moving objects such as drawers of desks and other objects.

In order to facilitate the movement of moving objects such as drawers of desks and other objects, sliding guide mechanisms in which rollers made of synthetic resin or metal are rotatably mounted have already been used. In this sliding guide mechanism, the shaft portion of a support shaft having a head is inserted into the shaft center of a roller formed in the shape of a disk or a round bar, and the shaft portion of the support shaft is protruded to the opposite side of the shaft portion. The end is attached to the object to be attached. Therefore, in such a sliding guide mechanism, when the roller is inserted into the groove as shown in FIG. 2, when the end surface of the roller comes into contact with the bottom of the groove, the friction causes It becomes difficult for the roller to rotate smoothly. For this reason, when such a sliding guide mechanism is installed in a desk drawer, for example, there is a problem in that the smooth sliding movement of the drawer becomes difficult due to the frictional force caused by the end surface of the roller coming into contact with the bottom surface of the groove. There is.

The present invention was developed in view of these conventional problems, and the present invention ensures smooth rotation of the roller even when the end surface of the roller comes into contact with the surface of a moving object or a fixed object opposite to it. The purpose is to enable smooth sliding movement of articles.

In order to achieve this purpose, in the present invention, annular protrusions that engage with each other are integrally provided inside the cylindrical outer roller on the rubbing surfaces thereof, and the same cylindrical outer roller is rotatably inserted. The inner roller is made longer than the outer roller, and one end surface of the inner roller protrudes from one end surface of the outer roller to overlap.
A spindle having a large diameter head is locked to the inner roller from the side from which the end surface of the inner roller protrudes, with the head placed inside the protruding end surface of the inner roller, and the shaft of this spindle is fixed. Provided is a sliding guide mechanism in which a spindle is rotatably inserted through the spindle, the end thereof protrudes to the opposite side, and the protruding end of the spindle is attached to an object by making both rollers mutually rotatable. It's in the middle of the day.

The sliding guide mechanism according to the present invention will be further explained based on the accompanying drawings. In the figure, 1 is a desk, 2 is a top plate, and on one side of the lower surface of the top plate 2, a pair of support walls 3 are provided substantially perpendicular thereto in the depth direction of the top plate 2. Reference numeral 4 denotes a drawer inserted between the support walls 3, 3, and side plates 5, 5 provided in the depth direction thereof.
A concave groove 6 is formed on the outer surface in the length direction thereof. Reference numeral 7 denotes a support plate, which is provided at one end of the support plate through a mounting wall 8 substantially perpendicular to the support plate on the outer surface of the rear wall 9 of the drawer 4 in a positional relationship that substantially overlaps with the bottom of the groove 6. It is something that The mounting hole 10 provided in the mounting wall 8 is a long hole extending in the depth direction of the groove 6 so that the mounting position of the support plate 7 can be adjusted in the depth direction of the groove 6. Reference numeral 11 denotes a pair of support rollers that are pivoted on the surface of the support plate 7 on the side of the groove 6, and these rollers are offset in the length direction of the groove 6, and in the width direction of the mouth of the groove 6. They are spaced apart.

Reference numeral 12 denotes a support rail having a concave cross-section and provided horizontally opposite to each other on the opposite sides of the support walls 3, 3;
This is formed to a size that allows it to slide within the groove 6. And these support rails 12,1
2 is inserted between the support rollers 11 and 11, and also inserted into the groove 6 to connect the drawer 4 to the support walls 3 and 3.
It is installed so that it can slide in between. Next, reference numeral 13 denotes a guide roller constituting the sliding guide mechanism according to the present invention, which is provided at the front end of the support rail 12 with its axis in the horizontal direction, and is also inserted into the groove 6. This is to allow the drawer 4 to slide smoothly by bringing the upper surface of the groove 6 into contact with the circumferential surface thereof. The guide roller 13 includes a cylindrical outer roller 14, a cylindrical inner roller 15 which is rotatably inserted into the inner roller 14, and a support rail 1 which is rotatably inserted into the inner roller 15 and becomes an attached object.
It consists of a support shaft 16 for attaching to 2. An annular protrusion 17 integrally protrudes from one end of the inner circumferential surface of the outer roller 14, which is the rubbing surface side, and an annular protrusion 17 integrally protruded from the other end of the outer circumferential surface of the inner roller 15, which is also the mutual rubbing surface side. At the same time, as shown in FIG. 8, the inner roller 15 is made slightly longer than the outer roller 14 so that the inner roller 1
Both rollers 14, 15 with one end surface of 5 protruding
is polymerized. Then, a support shaft 16 having a large-diameter head 19 is locked to the inner roller 15 with the head 19 placed inside the protruding end surface of the inner roller 15, and the shaft portion of the support shaft 16 is rotated. It can be inserted through it and the end protrudes to the opposite side. The ends of the support shaft 16 protruding from the rollers 14 and 15 are attached to the support rail 12 as an attached object so that the rollers 14 and 15 are mutually rotatable. Next, 20 is a resin plate provided on the support plate 7, and this support plate 7 is connected to the rail 1.
This is to prevent contact with 2.

This drawer 4 is constructed by sandwiching the support rail 12 from above and below with the support rollers 11, 11 of the support plate 7 provided at the end of the back side of the drawer 4.
A guide roller 13 is inserted into the groove 6, and its peripheral surface contacts the upper surface of the groove 6, thereby maintaining a horizontal state and sliding. Since the guide roller 13 is inserted into the groove 6, when the end surface of the guide roller 13 comes into contact with the bottom surface of the groove 6 due to the drawer 4 moving slightly in the left and right direction, the guide roller 13 is inserted into the groove 6. It is composed of outer and inner two-layered rollers 14 and 15, and the inner roller 1
Since the end surface of the guide roller 13 slightly protrudes from the end surface of the outer roller 14, even if the end surface of the guide roller 13 comes into contact with the bottom surface of the groove 6, it is only the end surface of the inner roller 15. Therefore, the inner roller 15 and the groove 6
Although friction occurs between the bottom surfaces of the outer roller 14, there is no problem with the rotation of the outer roller 14. Therefore, since the outer roller 14 rotates as the drawer 4 moves,
Unlike the rollers of this type of conventional sliding guide mechanism, the drawer 4 does not become difficult to slide.
Here, both of the outer and inner rollers 14 and 15 are made of synthetic resin or metal, or one is made of synthetic resin and the other is made of metal.

As described above, the sliding guide mechanism of the present invention has a two-layer structure of outer and inner rollers 14 and 15 that are rotatably overlapped with each other, and furthermore, the inner roller 15 is longer than the outer roller 14 so that the outer roller Since one end surface of the inner roller 15 is made to protrude from one end surface of the inner roller 14 and overlapped, the outer roller 14 can rotate without any problem even if the end surface comes into contact with the surface of an object facing it. Therefore, it is possible to always smoothly slide an object facing the roller or an object to which the roller is attached. Furthermore, since the inner roller 15 is simply inserted into the outer roller 14, the configuration is simple. Further, when both the outer roller 14 and the inner roller 15 can rotate, smoother sliding operation can be expected. Furthermore, since the head 19 of the spindle 16 is housed inside the inner roller 15, the outer roller 14 and the inner roller 15 can be made relatively wide to create the guide roller 13 of the required width, allowing smooth sliding. movement becomes possible.

In the illustrated embodiment, the sliding guide mechanism is provided in a desk drawer, but it can of course be provided in other furniture.
