Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a guide rail structure that guides the sliding door glass of vehicles, etc. do.

0002

[Conventional technology]

Conventionally, for example, as shown in FIG. Then, install the X-shaped frame mechanism A inside the door 2 and connect it to the regulator 3. Expansion and contraction from the upper part indicated by the solid line to the lower part indicated by the chain line as shown by arrows a and b. By doing so, the door glass support frame provided at the movable end of the frame mechanism A is Door glass 1 is generally raised and lowered by sliding 1a up and down. It is used in many ways.

0003 Then, in order to guide the sliding of door glass 1, Two groove-shaped guide rails 4 are provided in the door 2, or, although not shown, By providing one groove-shaped guide rail in the longitudinal direction of the section, as shown in Figure 6, this groove The inside of the groove 4a of the shaped guide rail 4 is filled with an inner sliding type attached to the door glass support frame 1a. The roller assy 5 is configured to slide.

0004 Usually, such a roller assembly 5 has its mounting legs 5 as shown in FIGS. 6 to 8. A rotating wheel 5b is provided at the tip of the groove-shaped guide rail. It fits into the groove 4a of the wheel 4 and slides while rotating. In this way, the guide rail structure for guiding the sliding of the door glass 1 is configured. has been done.

[0005]

[Problem that the idea aims to solve]

However, in such a conventional guide rail structure, the contact between the rotating wheel and the groove is limited. The contact surface rotates in the rolling direction on one side with respect to the direction of travel, but does not roll on the other side. Since it rotates in the opposite direction, the frictional resistance on the other side becomes very large, causing sliding movement. There is a risk of making it heavier.

[0006] In addition, the flat surface of the rotating wheel also has a large frictional resistance with the inner surface of the groove, which causes low There is also a risk that the smooth sliding of Raassi will be hindered.

[0007] The present invention was devised in view of these issues, and consists of three edges with a Y-shaped cross section. A guide rail consisting of A roller assembly having a Y-shaped groove is inserted into the roller assembly, and a Y-shaped three By interposing several ball bearings between each edge, frictional resistance is reduced. The purpose is to provide a guide rail structure that can slide smoothly and easily with less friction. do.

[0008]

[Means to solve the problem]

Therefore, the guide rail structure of the present invention has a guide rail and a structure along the guide rail. In a guide rail structure consisting of a roller assy that slides, the guide The rail is formed by three edges having a Y-shaped cross section, and the three Y-shaped edges of the guide rail are At the facing part of the roller assembly that is fitted to the guide rail so as to surround it from the periphery. , a Y-shaped groove is formed to pass through the three Y-shaped edges, and a Y-shaped groove is formed in the roller assembly. is characterized by several ball bearings interposed between the three Y-shaped edges. It is said that

[0009]

[Effect]

In the guide rail structure of the present invention described above, the guide consists of three edges forming a Y-shaped cross section. The inner surface of the roller assembly fitted into the guide rail so as to surround the rail. Several ball bearings are interposed between the guide rail and the three edges of the guide rail. As a result, the roller assembly has support surfaces from three directions relative to the guide rail. This results in a stable and low sliding friction.

【Example】

Hereinafter, embodiments of the present invention will be explained with reference to the drawings. Figure 1 shows the guide rail structure as an example of this guide rail structure. 2 is a side view of the guide rail structure, and FIG. 3 is a perspective view of the guide rail structure shown in FIG. The cross-sectional view and FIG. 4 are perspective views of the roller assemblies. The same symbols indicate almost similar parts.

[0011] First, the present guide rail structure shown in Fig. 1 is suitable for use with a vehicle door as shown in Fig. 5, for example. It is used to guide the raising and lowering of Agulhas 1.

0012 The guide rail 6 according to the present invention is arranged at approximately equal intervals as shown in FIGS. 1 and 2. It is formed by three edges 6a, 6a, 6a with a Y-shaped cross section that spreads across the gap, and its configuration is For example, as shown in Figure 3, two symmetrically bent edges are joined back to back. , this joint portion serves as the mounting support edge 6b.

[0013] In addition, the roller assembly 7 is connected to the Y-shaped guide rail as shown in FIGS. 1 to 4. It is formed of a box-shaped case 7a that surrounds the three edges 6a of 6, and its slide If a Y-shaped groove 7b through which the three Y-shaped edges 6a are inserted is formed on the opposite surface in the direction, In addition, an upright door glass mounting leg 7c is provided in the orthogonal direction. ing.

[0014] The Y-shaped groove 7b of such a roller assy 7 is inserted into the three Y-shaped edges 6a. In this way, fit it onto the Y-shaped guide rail 6, and connect it to the inner surface of the roller assembly 7 and each of the three edges. 6a, there are several ball bearings 8 (about 2 to 3 on each edge). is interposed, thereby forming an externally sliding roller assembly 7.

[0015] Therefore, the relationship between the Y-shaped guide rail 6 and the external sliding roller assembly 7 is supported by ball bearings 8, so that the mutual positional relationship is always maintained stably. It has become a state.

[0016] The external sliding roller assembly 7 is supported by several rotating ball bearings 8. so that it slides smoothly along the length direction of the Y-shaped guardrail 6. It's now working.

[0017] This guide rail structure configured as described above uses one rotating wheel as in the conventional one. 5a fits into the groove-shaped guide rail 4 to support an internal sliding roller assembly. Instead of a built-in structure, the Y-shaped guide rail 6 should be surrounded. Several ball bearings 8 are interposed between the three edges 6a of the guide rail 6, and the outer slide Since the movable roller assembly 7 is fitted and supported, the Y-shaped guide The holding relationship between the rail 6 and the external sliding roller assembly 7 is always maintained without wobbling. It is maintained stably.

[0018] In addition, a Y-shaped guide rail 6 with several ball bearings 8 interposed therein and an outer sliding There is very little frictional resistance between the shaped roller assembly 7 and the sliding movement. The work is done smoothly and easily.

[0019] Therefore, the door glass 1 equipped with such a guide rail structure is It can be operated easily.

[0020] In addition, the guide rail structure according to the present invention can only be used for the above-mentioned door glass. Of course, it can also be applied as a guide rail structure for other slide guides. be.

[0021]

[Effect of the idea]

As described in detail above, the guide rail structure of the present invention has a guide rail and a guide rail. In a guide rail structure consisting of a roller assy that slides along the rail. , the guide rail is formed of three edges having a Y-shaped cross section, and the Y of the guide rail is The roller assembly is fitted onto the guide rail so as to surround the three edges of the shape. A Y-shaped groove is formed on the facing part of the roller, and a Y-shaped groove is formed through which the three Y-shaped edges are inserted. Several ball bearings are interposed within the assembly between the three Y-shaped edges. Therefore, the roller assembly is fitted with three Y-shaped edges and several ball bearings. The holding relationship with the guide rail is very stable, there is no wobbling, and there is no frictional resistance. There is less resistance, which makes the sliding of the sliding object attached to the roller assy easier. It has the effect of being stable, smooth and light.
