Position adjustment was possible.

[0004] In the conventional configuration as described above, in the case of a telescopic guide rail, variations in the thickness of the vertical plate portion of the guide rail, the thickness of the backing plate, or the thickness of the spring washer used together are accumulated. The total thickness of these plate thicknesses is greater than the length of the large-diameter shaft portion of the stepped bolt, and therefore, when the stepped bolt is fastened, the vertical plate of the telescopic guide rail between the backing plate and the tap plate It is not possible to secure a gap that allows the part to move in the rail length direction,
This may hinder smooth thermal expansion and contraction of the telescopic guide rail.

In addition, it is necessary to prepare a bolt and a tap plate for an extension guide rail and for an adjustment guide rail, and to use these separately, which not only increases the cost but also deteriorates the workability.

13b is fastened and fixed together using two inside bolts 9 and two inside bolts 10. A pair of mounting plates 15a, 1 fixed on the upper ends of the guide rail suspension yoke 11 by fixing members 14 such as rivets.
5b is provided, and the guide rail suspension yoke 11 is connected to the guide rail suspension beam via the mounting plates 15a, 15b, a pair of pressing plates 16a, 16b, and a plurality of bolt nuts 17 connecting the both. It is suspended from the material 18.

The connection structure between the guide rails 1 and 2 by the abutment plate 7 and the tap plate 8 and the bolts 9 and 10 will be described in further detail. The through holes 19a and 19a have a diameter slightly larger than the outer diameter of the bolts 9 and 10. The contact plate 7 provided with 19b
Are ridges 5 for holding the mounting members of the guide rails 1 and 2
a between the guide rails 1 and 2 so that the upper and lower sides are fitted between the vertical rails 3a and 5b and the vertical plate 3 and the upper side is in contact with the lower surface of the upper horizontal rail 4a. Applied to the side. The tap plate 8 provided with the screw holes 20a and 20b into which the bolts 9 and 10 are screwed is fitted between the mounting member holding ridges 6a and 6b of the guide rails 1 and 2 and has an upper side. The two guide rails 1 and 1 are brought into contact with the upper mounting member holding ridge 6a.
It is applied to the other side of the vertical plate portion 3 between the two.
For the fixed guide rail 1, the bolt 9 that passes through the through hole 19 a on the backing plate 7 side and the through hole 21 provided in the vertical plate portion 3 of the fixed guide rail 1 is screwed into the tap plate 8. By screwing into the hole 20a,
The contact plate 7 and the tap plate 8 are pressed and fixed to both side surfaces of the vertical plate portion 3.

On the other hand, the bolt 10 on the movable guide rail 2 side
As shown in FIGS. 3B and 3C, the distance piece 22 having a plate thickness t2 slightly larger than the plate thickness t1 of the vertical plate portion 3 of the movable guide rail 2 or, as shown in FIGS.
A distance piece 23 having a plate thickness t3 slightly smaller than the plate thickness t1 of the vertical plate portion 3 of the movable guide rail 2 is loosely fitted.
The outer diameter and the inner diameter of these distance pieces 22 or 23 are the same. Further, a through hole of the bolt 10 provided in the vertical plate portion 3 of the movable guide rail 2 is formed in an elongated hole 24 so that the distance piece 22 or 23 can float within a predetermined range in the rail length direction. I have. 2

The bolt 10 penetrating the movable guide rail 2 through the through hole 19b on the side of the backing plate 7 and the long hole 24 provided in the vertical plate portion 3 Is screwed into the screw hole 20b.
At this time, the distance piece 22 or 23 through which the bolt 10 passes is loosely fitted in the long hole 24. Therefore,
When the thicker distance piece 22 is used as shown in FIG. 3B, the backing plate 7 and the tap plate 8 are fixed to the both side surfaces of the distance piece 22 by press-fastening by fastening the bolt 10. The vertical plate portion 3 of the movable guide rail 2 sandwiched therebetween is not pressed and fixed, and the movable guide rail 2 is moved within a rail length direction play range between the elongated hole 24 and the distance piece 22. It can move in the rail length direction between the contact plate 7 and the tap plate 8. In other words, when the movable guide rail 2 is used as a telescopic guide rail for absorbing thermal expansion and contraction, the thicker distance piece 22 may be used.

When the thinner distance piece 23 is used, as shown in FIG. 4A, the backing plate 7 and the tap plate 8 are moved between the two by fastening the bolt 10. Vertical plate part 3 of guide rail 2
Will be pressed and fixed to both sides of the. In this case, the movable guide rail 2 does not move in the rail length direction unless the bolt 10 is loosened, but by loosening the bolt 10, the rail length between the long hole 24 and the distance piece 23 is reduced. It can be moved in the rail length direction between the backing plate 7 and the tap plate 8 within the directional play range. In other words, when using the movable guide rail 2 as an adjustment guide rail for adjusting the position of the rail end, the thinner distance piece 23 may be used.

Since the movable guide rail 2 is supported on the upper side of the backing plate 7 and the tap plate 8 so as to be movable in the rail length direction, the movable guide rail 2 is simply fixed to the fixed guide rail 1 in a fixed position. If you just connect,
It is not necessary to use the distance piece 23 (elongated hole 2).
The vertical play between the bolt 4 and the bolt 10 may be large.) Of course, also in this case, by loosening the bolt 10, the position of the movable guide rail 2 can be adjusted within the play range in the rail length direction between the elongated hole 24 and the bolt 10.

[0016]

As described above, according to the guide rail connecting device of the present invention, the distance plate that fits loosely into the long hole provided in the vertical plate portion of the movable guide rail is provided with the contact plate and the tap plate. Between the movable guide rail and the vertical plate portion of the movable guide rail. As long as the thickness of the distance piece is greater than the thickness of the plate portion, the movable guide rail does not hinder play in the rail length direction, and therefore, the movable guide rail is provided with a telescopic guide for absorbing thermal expansion and contraction. It can be effectively used as a rail. Also, by simply removing the distance piece, the vertical plate portion of the movable guide rail can be sandwiched and fixed between the backing plate and the tap plate while using other components such as bolts and tap plates as they are. In this case, since the movable guide rail can be moved in the rail length direction to adjust the position by loosening the bolt, the movable guide rail can also be used as an adjustment guide rail for adjusting the end position of the rail. Can be used.

According to the second aspect of the present invention, other components such as bolts and tap plates can be obtained simply by replacing the distance piece with a thinner one than the thickness of the vertical plate portion of the movable guide rail. Can be used as it is, and the vertical plate portion of the movable guide rail can be sandwiched and fixed between the backing plate and the tap plate. In this case, too, the movable guide rail is moved in the rail length direction by loosening the bolt. The movable guide rail can be used as an adjustment guide rail for adjusting the end position of the rail because the movable guide rail can be adjusted by moving the movable guide rail.
Adjust the position adjustment range of the movable guide rail in the rail length direction.
When used together with the thicker distance piece as a telescopic guide rail, the rail telescopic movement range can be made the same, and when the bolt is strongly tightened, the peripheral part of the bolt on the backing plate or tap plate is in the elongated hole The extent to which the movable guide rail is deformed so as to be inserted can be suppressed by the distance piece, and fine adjustment of the position of the movable guide rail when the bolt is loosened can be facilitated.

If the lower end of the guide rail suspension yoke is fixed together with the bolts to the outside of the backing plate, the connection between the fixed guide rail and the movable guide rail can be established. At the same time, this connection can be easily suspended.
