Abstract

PROBLEM TO BE SOLVED: To ensure easy mounting on a body, a good appearance near lot guides and simple assembling structure and process by mounting the lot guides, covering the outer periphery at one end or at both ends of a corrugate in a slidable manner, on coaxial shafts protruded from both ends of the corrugate. SOLUTION: A pair of coaxial shafts 3, 4 to support a cylinder 2 in a rotatable manner are protruded from the right and left ends of a corrugate 1 and bottomed cylindrical lot guides 5, 6 covering the outer peripheries at both ends of the corrugate 1 in a slidable manner are inserted into the ends of the coaxial shafts 3, 4 via through-holes 5a, 6a. A blind winder has a recess prepared on the body side of an automobile to accept the outer ends of the coaxial shafts 3, 4, so that the ends of the coaxial shafts 3, 4, being pushed into the cylinder 2, can be mounted into the recess against the axially repulsive force of a coiled torsion spring or removed therefrom for mounting/demounting operation.

2. Description of the Related Art As a conventional blind winding device for an automobile, a tubular body around which a blind sheet is wound is rotatably supported by a pair of left and right coaxial shafts, and a coil-shaped torsion spring installed in the tubular body. There is widely known a structure in which the end portion of is connected to the tubular body and the coaxial shaft to apply a sheet rewinding force to the tubular body.

FIG. 4 shows such a conventional blind winding device for an automobile. In FIG. 4, reference numeral 21 denotes a corrugate for accommodating a cylindrical body 22 around which a blind sheet is wound. A torsion spring (not shown) is provided, one end of which is attached to the tubular body, and the other end of which is attached to a coaxial shaft (not shown) that rotatably supports the tubular body.

Both ends of the corrugated body 21 are supported by cylindrical rod guides 23 and 24 which cover the outer circumference of the corrugated body. Furthermore, these rod guides 23, 2
4 are respectively accommodated in tubular caps 25 and 26 so as to be slidable in the axial direction.

Each of the caps 25, 26 is formed with a guide long hole 27, 28 of a predetermined length in the axial direction, and the tapping screw 2 is passed through these guide long holes 27, 28.
9 and 30 are rod guides 23 and 24 and corrugated 2
1 is screwed onto the outer circumference of both ends.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a blind winding device for an automobile of the present invention by cutting a main part thereof, in which FIG. 1 is a corrugate having a tubular body 2 constituting a blind winding part described later. .

Further, a pair of coaxial shafts 3 and 4 for rotatably supporting the cylindrical body 2 project from the left and right ends of the corrugate 1, and the corrugated 1 is attached to the ends of the coaxial shafts 3 and 4. The bottomed cylindrical rod guides 5 and 6 slidably covering the outer peripheries of both ends are fitted and inserted in the through holes 5a and 6a.

Then, retaining rings 7 and 8 are fitted and inserted at the penetrating ends of the coaxial shafts 3 and 4 with respect to the rod guides 5 and 6, respectively, and the retaining rings 7 and 8 and the coaxial shafts 3 and 4 described above. At the penetrating end, retaining pins 9, 1
0 is inserted.

FIG. 2 is a sectional view showing the fitting structure of the rod guides 5 and 6 with respect to the corrugate 1, and the corrugate 1 is shown by a chain double-dashed line.

The blind winding portion having the cylindrical body 2 has a structure as shown in FIG. That is, the blind winding portion A is the blind sheet 11
The cylindrical body 2 around which is wound is rotatably supported by the pair of left and right coaxial shafts 3 and 4, and the end portions 12A and 12B of the torsion spring 12 provided in the cylindrical body 2 are attached to the cylindrical body 2. It is configured so as to apply a sheet rewinding force to the tubular body 2 by connecting to a later-described inner bush 16 which is integral with the later-described bush 13 and the coaxial shaft 4 which are integral with each other.

In the blind winding portion A, bushes 13 and 14 are fixed to both ends of the tubular body 2, and the coaxial shaft 4 is held rotatably and slidably in the axial direction. The coaxial shaft 3 is rotatably held.

The inner bush 16 is provided inside the tubular body 2 so as to be rotatable and axially slidable. The inner bush 16 is provided with an end portion of one coaxial shaft 4. It is fixed. The other coaxial shaft 3 has a structure that engages with the inner bush 16 in the rotational direction and is slidably fitted in the axial direction.

That is, the inner bush 16 is formed with a sliding hole 16A located at the axial center of the inner bush 16 for slidably fitting the end portion of the coaxial shaft 3, and on both sides thereof.
A slit 16B extending in the axial direction is formed, and a slide pin 15 that slides in the slit 16B is attached to the coaxial shaft 3.

Further, the coil-shaped torsion spring 12 has an elastic holding function of elastically holding the tubular body 2 in the winding direction with respect to the coaxial shafts 3 and 4, and also has a coaxial shaft 4 toward the outer end of the tubular body 2. It has the function of holding the axis in the axial direction.

Therefore, the coiled torsion spring 12 is housed in the tubular body 2 in a state of being compressed in the axial direction, and the one end 1
2A is fixed to the bush 13 and is connected to the tubular body 2 via this, and the other end 12B is connected to the inner bush 1
It is fixed to 6 and is connected to the coaxial shafts 3 and 4 via this.

The blind winding device constructed as described above has the coaxial shaft 3,
Since a concave portion (not shown) for receiving the outer end portion of 4 is prepared, the coaxial shaft 3 or 4 is pushed into the tubular body 2 against the axial repulsive force of the coiled torsion spring 12. Then, the coaxial shafts 3 and 4 can be attached and detached by mounting the ends of the coaxial shafts 3 and 4 in the recesses or by removing them from the recesses.

The coiled torsion spring 12 not only has the function of rewinding the blind sheet 11, but also has the elastic function of catching the extension of the coaxial shafts 3, 4 to the outside. Since it is not necessary to use a spring or the like, the number of parts can be reduced, the internal structure of the tubular body 2 can be greatly simplified, and the cost can be reduced.

Since the tubular body 2 is housed in the corrugated body 1 and the outer circumferences of both ends of the corrugated body 1 are covered by the rod guides 5 and 6 having a bottomed cylindrical shape, parts such as screws and springs can be installed. The exposed parts of parts such as mounting parts are not generated, the appearance is improved, and the cost can be reduced by reducing the number of parts.

[0025]

As described above, according to the present invention, a rod guide is provided in a corrugate for rotatably accommodating a tubular body so as to draw out a blind sheet, and slidably covers the outer periphery of both ends of the corrugate. Since it is configured to be attached to each coaxial shaft protruding from both ends of the corrugate, the rod guide can be slidably supported with respect to the corrugate while being easily mounted on the vehicle body, and the appearance around the rod guide part can be improved. It is possible to obtain favorable effects such as good manufacturing cost, simplification of assembly structure and process, and cost reduction by reducing the number of parts.
