Description

TECHNICAL FIELD The present invention relates to a window glass lifting device that slides vertically to open and close, and is used, for example, in a window of an automobile door.

"Prior Art" As a conventional window glass lifting device, for example, Japanese Patent Laid-Open No. 55-1
There is one disclosed in Japanese Patent No. 4231.

That is, in the publication, guide rails are arranged in front of and behind an inner panel of a door serving as a mounting portion, and guide plates serving as carriers for consolidating and ascending and lowering a window glass are vertically movable via rollers on the respective guide rails. The endorsement is disclosed.

However, in the above-mentioned window glass opening / closing device, the mutual positional relationship between the respective members is not fixed before installation, and thus is in an unstable state, so that the assembling workability is extremely poor, which impedes rationalization. There is a defect.

Therefore, as a solution to this, a frame-shaped base member is formed by firmly connecting the upper and lower sides of a pair of guide rails arranged in parallel along the ascending / descending trajectory of a window glass with a base plate having a reinforcing flange standing upright on the outer periphery. Has been proposed, and a lifting device is constructed based on this base member.

[Problems to be Solved by the Invention] However, in such a lifting device, the reinforcing flange provided on the outer periphery in order to increase the rigidity of the base plate interferes with a part of the carrier. The carrier must be fitted to the guide rail before assembling the members, which causes a problem of poor workability in assembling the lifting device.

The present invention has been made in view of such conventional problems, and provides a window glass lifting device that solves the above problems by allowing a carrier to be mounted after the base member is assembled. It is an object.

"Means for Solving Problems" The gist of the present invention for achieving such an object is a window glass lifting device that slidably supports a window glass, and The top and bottom of a pair of guide rails that are juxtaposed alongside each other are fixed by a base plate with a reinforcing flange standing upright on the outer periphery to form a frame-shaped base member, and the carrier can be moved up and down on at least one of the guide rails. And a structure capable of fixing the lower part of the window glass to the carrier while being fitted to, the flange of the outer periphery of the base plate of the base member,
A window glass raising / lowering device is characterized in that a notch for allowing a part of a carrier to pass therethrough is provided.

[Operation] Then, the elevating device is constructed based on the flat frame-shaped base member as a whole, and in assembling the elevating device, first, the upper and lower base plates are respectively attached to the upper end portion and the lower end portion of the guide rail. A base member is formed by solidifying, and each member is assembled on the basis of this base member.

The carrier may be mounted at the most appropriate time for assembling the elevating member, and the carrier is inserted from the end of the guide rail, fitted therein, and moved to the operating position. Since a part of the carrier does not interfere with the base plate and the flange, there are few restrictions in the process, and the optimum assembly process can be set.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 2 to 4, the elevating device 10 is mounted on the door A to elevate the window glass B.
Groove opening A1 in which the window glass B appears and disappears at the upper end of the door A body

And a drive unit 50 is installed on the drive base 22. The drive unit 50 includes a drive motor 51, a speed reduction mechanism 52, and a drive pulley 53.

Since the driving unit 50 requires a large driving force, there is a limit to downsizing, and the driving unit 50 is placed in an inclined posture so as to be properly housed between the guide rails 30 and 30 and is flat enough not to project largely from the flat base member 20. The shape is set and arranged.

Further, as can be seen from FIG. 1 to FIG. 7, carriers 60, 60a having the same structure except for a part thereof are respectively provided with guide rails 30, 30 via roller units 70 rotatably fitted to the guide rail 30. It is mounted so that it can move up and down.

The roller unit 70 is integral with and forms a part of the carriers 60, 60a. One carrier 60 is connected to the drive cable 11 on the drive side and the other carrier 60a.
Is a driven side and is movably attached to the guide rail 30 without being connected to the drive cable 11.

Explaining the drive-side carrier 60, the carrier 60 is a base in which a carrier plate 61 to which the window glass B is fixed and a drive plate 62 to which the drive cable 11 is connected are connected by a roller support portion 63. ing. The carrier plate 61 is vertically provided with insertion holes for fastening bolts for fixing the lower end portion of the window glass B.

The drive plate 62 extends along the surface of the window glass B,
A connecting end 64 is formed at the tip of the driving plate 62 so as to be recessed inward from the surface 62a, and upper and lower wall portions which fall from the surface 62a form connecting surfaces 64a and 64a.

The notch 42 formed in the end flange 41c of the base plate 40 is a driving plate 62 of the driving side carrier 60.
Is set to a depth such that the connecting end 64 can pass.

On the connecting surfaces 64a, 64a, the end portion of the drive cable 11 which is lowered from above and the drive cable 1 which is extended from below
1 and the ends thereof are connected to each other. That is, the end member 12 is fixed to each end of the drive cable 11, and the neck portion 11 a at the end of the drive cable 11 is connected to the connecting end 6.
4 is inserted into the connecting surface 64a and the end member 12 is connected to the connecting end 6
It is engaged so that it does not come off from 4.

One end of each end of the drive cable 11 is locked to the end members 12 of the drive cable 11, and springs 65, 65 for absorbing the slack that bias the drive cable 11 in the pulling direction are attached to the drive plate 62.

Rollers 71, 71 forming a roller unit 70 are pivotally supported on the upper and lower ends of the roller support portion 63 via pivots 72, 72, and the back plate 7 is provided between the tips of the pivots 72, 72.
3 is installed, and a flat roller 74 is arranged between the rollers 71, 71.

The outer periphery of the rollers 71, 71 is the side wall 31 of the guide rail 30.
It is slidably slidably in contact with the groove 32.

Roller support 63 of carrier 60 and back plate 73
The base end portion of the rocking lever 75 is pivotally attached to the guide rail 30 via a pivot shaft 76, and the guide rail 30 is attached to the base end portion of the rocking lever 75 via an eccentric shaft 77 slightly eccentric to the pivot shaft 76.
A flat roller 74 is rotatably supported on the side wall 33 so as to be slidably slidably contacted.

The swing lever 75 is biased clockwise in FIG. 7 by a spring 78 stretched between the swing lever 75 and the back plate 73, and the flat roller 74 is pressed against the side wall 33. As a result, the roller unit 70 is slidably fitted to the guide rail 30. The driven-side carrier 60a has a base portion composed only of a carrier plate 61, and the roller plate 63 is formed by bending the carrier plate 61.
The roller unit 70 is attached there.

In order to assemble the windowpane elevating / lowering device 10 having the above-described configuration, first, the shape of the base member 20 which is a frame is solidified.
The base plates 40, 40 are arranged vertically and the drive base 22 is arranged in the middle, and the upper and lower ends of the guide rails 30, 30 are brought into contact with the side flanges 41a, 41b of the respective base plates 40 and welded. Components that are not integral with the base member 20 are assembled after the base member 20 is assembled.

That is, after the base member 20 is assembled, the drive unit 5
0, drive cable 11 and other components are assembled. The drive-side carrier 60 should be installed at the most appropriate time during the process of assembling the other components.

The carrier 60 on the drive side is fitted into the guide rail 30 from the end of the guide rail 30 in which the notch 42 is cut in the end flange 41c of the base plate 40. When the drive-side carrier 60 is inserted, the inwardly fitted connecting end 64 passes through the portion of the notch 42, so that the drive-side carrier 60 can be moved to the operating position without interference.

When assembling the window glass to the door A that is the mounting portion of the elevating device 10, the flat glass is used and inserted into the door A that is the mounting portion from the groove opening A1.

That is, since the lifting device 10 is unitized flat as a whole on the basis of the base member 20, the lifting device 10 is installed in the groove opening A without the window glass B attached.
The whole can be inserted into the door A from 1 in a straight posture, and the mounting bolts 21 can be screwed into the upper and lower weld nuts 44a, 44b ... It can be very easily fixed to the mounting portion.

Similarly, the window glass B is vertically inserted into the mounting portion from the groove opening A1, and the carrier plates 61 of the carriers 60 and 60a are fixedly coupled to the lower end portions thereof.

If the drive motor 51 of the drive unit 50 is operated, the reduction mechanism 5
Since the drive pulley 53 is rotationally driven via 2 and the drive cable 11 is driven in the axial direction of the drive cable 53, the carrier 60a connected to the drive cable 11 also moves up and down, and the window glass B is opened and closed. The slack of the drive cable 11 that occurs on the relaxation side during lifting and lowering is pulled and absorbed by the corresponding spring 65.

When the window glass B is opened and closed, the guide rails 30, 3
The roller unit 70 fitted to 0 moves up and down while being guided. However, since the flat roller 74 is pressed against the side wall 33 by the elastic force of the spring 78, the roller 71 and the flat roller 74 widen each other. Since the roller 71 is biased in the direction, the roller 71 fits into the groove 32 and comes into pressure contact with the side wall 31,
The flat roller 74 is pressed against the side wall 33.

The urging force of the spring 78 is increased by the lever action due to the eccentricity of the pivot 76 that pivotally supports the swing lever 75 and the eccentric shaft 77, and the flat roller 74 is strongly pressed against the side wall 33.
Even if there is an error in the direction in which 2 is separated from the side wall 33,
The roller unit 70 moves the roller 7 by the urging force of the spring 78.
1. The guide rail 30 is fitted through the plane roller 74 without rattling.

[Advantages of the Invention] According to the windowpane raising / lowering device of the present invention, a notch for allowing a part of the carrier to pass through a reinforcing flange provided on the outer periphery of the base plate that fastens the end of the guide rail. Since the above is provided, when assembling the lifting device, there is no limitation on the mounting time of the carrier, and the carrier can be mounted at the most appropriate time, so that the assembling process can be most rational. Since the overlapping portions are provided with the notches so as to be able to dodge in the thickness direction, it contributes to the reduction of the thickness of the entire lifting device.
