Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a hanging wheel device for a suspension type sliding door used in a vehicle or the like.

[Conventional technology]

Conventionally, in a suspension type sliding door, a mounting bracket (2) having a door wheel (1) constituting a hanging wheel device for opening and closing the sliding door was installed at the top of the sliding door (3) as shown in Figures 8 and 9. Bones!
1 (4) with rivets (5) or welding means.

Each of these conventional hanging wheel devices A has a sliding door (
Since it is firmly attached to the frame (4) of 3) using rivets (5) or welding means, a large number of attachment points (Fig. 9) are required for each relatively small mounting bracket (2). In addition, it is difficult to ensure dimensional accuracy using welding methods, requires finishing treatment to prevent the effects of heat, and not only does it have to be installed during the sliding door assembly, but it is permanently fixed, which poses maintenance problems. .

In addition, as mentioned above, rivet installation requires a large number of attachment points, which requires a large number of holes to be drilled and rivets, which is time-consuming and requires a lot of effort to support the weight of the sliding door. As strength is also required, the diameter of the rivet becomes thicker, which causes problems such as the rivet hammer becoming larger and requiring more labor.

Furthermore, as shown in FIG. 8, when the door axle 6 with the door roller 1 and the mounting bracket 2 are fastened using bolts and nuts 7, these bolts and nuts 7 largely protrude from the mounting bracket 2, which saves space. Moreover, as shown in FIG. 10, when the door axle 6 and the mounting bracket 2 are attached by welding means to solve the above-mentioned problem, the influence of heat cannot be avoided as mentioned above. However, there are problems such as not being able to perform a painting process in advance and requiring post-processing for finishing.

[Means for solving problems]

The structure of the present invention that solves the problems of the prior art is that the mounting bracket of the door roller and the frame of the sliding door are provided with engaging portions that engage with each other and slide only in the lateral direction, thereby preventing mutual movement of the mounting bracket and the frame. is characterized by being locked with a slide stopper.

[Function] This invention provides an engagement relationship that allows sliding only in the lateral direction between the frame of the sliding door and the mounting bracket of the door roller, which have not been related to each other in the past, so that they slide and engage with each other, and then the sliding door is closed. By doing this, the installation of the door roller is completed.

All of the weight of the sliding door is applied to the engaging portions, and the slide stops simply prevent each other from sliding apart, so the slide stops themselves do not require any particular strength. Therefore, it can be configured with a rivet, Pol I, or other stopper with a smaller diameter than conventional ones.

Furthermore, even if it becomes necessary to remove the strap device for maintenance or the like, it is only necessary to remove the slide stopper, and there is no need for the conventional restrictions such as permanent attachment.

〔Example〕

The present invention will be described in detail with reference to FIGS. 1-4.

Fig. 1 is a partially cutaway side view of the main part, Fig. 2 is a partially cutaway side view of the main part of another embodiment, Fig. 3 is a front view of the main part showing the connection between the door roller mounting bracket and the sliding door. FIG. 4 is a front view of main parts of another embodiment same as the above.

Reference numeral 11 shown in FIG. 1 is a sliding door, and the frame 12 at the top of the sliding door 11 is shaped like an upward U-shape, and its - side rising side is 12 m.
is fixed to the sliding door 11 with screws 13, and an engaging portion 14 having upwardly inclined surfaces 14a formed on the upper and lower sides is integrally provided on the inside of the other side upright side 12b. Reference numeral 15 denotes a mounting bracket on which a door wheel 17 is rotatably attached to a door axle 16 fixed to the upper end thereof, and a dovetail groove 15a into which the engaging portion 14 of the frame 12 is loosely fitted is provided on the outside of the lower end of the mounting bracket 15. Form a dovetail groove of 15 m with the above frame 1.
The lower part of the bone tIfi 12 and the mounting bracket 15 is loosely fitted in the engagement part 14 of the second part so as to be slidable only in the lateral direction.
It is fixed with a slide stopper 18 passing through one side of the sliding door 11.

FIG. 2 shows a dovetail groove 19 formed on the inner surface of the bottom side 12c of the upward U-shaped bone M112 in the embodiment shown in FIG. It is loosely fitted so that it can slide only in. A notched cross section 15c formed in the middle of the mounting bracket 15 is loosely fitted into the upper corner portions of both upright sides 12a and 12b of the frame 12, thereby stabilizing the mounting bracket 15.

The framework 12 and/or the fittings 15 are optimally constructed from extruded aluminum sections, but may also be realized using other materials.

Figures 3 and 4 show the connection structure between the mounting bracket and the sliding door.
In FIG. 3, fittings 15 fitted to the frame 12 are provided at both ends of the sliding door 11, and between these fittings 15, there is a short and
An intermediate member 20 having a dovetail groove 15a that loosely fits into the engaging portion 14 of the frame 12 is interposed, and both mounting brackets 15 are attached to both ends of the intermediate member 20, and both mounting brackets 15 are attached to both ends of the sliding door 11. A stopper 18 for sliding outward is attached.

Also, the mounting structure shown in Figure 4 is similar to the mounting structure shown in Figure 3 above.
and an intermediate member 20 are integrated. In this case, the slide stop 18 can be provided at any location other than the outer side of both mounting brackets 15 as shown in FIG.

5 to 7 show the mounting structure of the mounting bracket 15 and the door axle 16, and as shown in FIG. be done.

A groove 22 having a square or U-shaped cross section is formed around the end of the door axle 16, and the groove 22 is filled with the material of the mounting bracket 15, which has been deformed by pressing the part indicated by the arrow in the figure. (Fig. 6) and fixes the door axle 16 to the mounting bracket. This groove 22 should have sufficient depth and width to fix the door axle 16.

Moreover, the above-mentioned A 22 is not provided around the entire circumference of the door axle 16,
As shown in FIG. 7, it may be provided partially.

In this case, the locking force of the door axle 16 against the mounting bracket 15 acts even more strongly. The best material for the mounting bracket 15 that provides this effect is aluminum.

According to such a configuration, the problems of the prior art can be completely and easily solved.

〔effect〕

As mentioned above, the structure of the present invention, that is, the mounting bracket and the frame,
Since they are configured to slide into engagement with each other only in the lateral direction and are fixed to the sliding door with a slide stopper, the following effects can be obtained.

(,) Manufacturing accuracy is improved in the connection between the mounting bracket and the frame.

(b) Unlike conventional methods, there is no need for many strong rivets, and the entire load of the sliding door is applied to the engaging part.
The slide stopper itself does not require special strength.

(e) Even if it becomes necessary to remove the suspension device for maintenance, etc., it is sufficient to simply remove the slide stopper, and there is no restriction such as having to permanently attach it as in the past.

(d) Since the heat effect of welding is eliminated, finishing work can be omitted.

(e) It can be installed after the sliding door is completed, and disassembly and maintenance is also possible and easy.

(f) There is no restriction on the manufacturing process.
