Description
Background of the Invention
1. Field of the Invention
The present invention relates to a sun visor, particularly for automotive vehicles, and having a flipover mirror, or mirror which can be reversed so that its reflective side can be selectively covered or exposed.
2. Description of the Prior Art
Vehicle sun visors are to an increasing extent provided with mirrors. For various reasons, such as avoiding the danger of driver or passenger dazzling, they are provided with mirror covers. Mirror covers generally are flaps, which are pivoted to the sun-visor body above or below the mirror. Such flaps must be separately manufactured and then fastened to the sun visor. This increases the cost of manufacture of the sun visor, particularly as the sun visors and their flaps must also include means which make it possible to hold the flaps in their closed or opened positions.
Summary of the Invention
The object of the present invention is to create a vehicle sun visor which has a coverable or flipover mirror and in which no elements separate from the mirror need be brought over the mirror in order to cover it, enabling the sun visor to be manufactured in a simpler and more economical fashion.
In accordance with the invention, the mirror is arranged on the sun visor so that it can be reversed. By merely turning the mirror over, its reflective side can be brought into a covered or a viewable position, enabling a flap or similar covering means to be dispensed with.
The invention can be reduced to practice in various ways. In the case of a mirror consisting of a suitable metallic or metallized material, it is possible to mount the mirror on the sun visor by a magnet attached to the visor. It is furthermore possible to provide the sun visor with spring clamps, or the like, which grip around the mirror at two opposite edges and thus hold the mirror on the sun visor in such a way that it can be repeatedly detached.
However, the mirror according to the invention is preferably not connected in a removable manner to the sun visor. The mirror is instead arranged swingably around one edge, and that edge is displaceable by translation along the sun visor. It is advantageous for the mirror to have a hinge axis on one edge which is received in a displaceable manner in lateral guides arranged on the sun visor. Alternatively, the mirror may be provided on one edge with hinge axis pins, the ends of which axis pins engage into bearing pedestals which themselves are received for translation in slot guides along the sun visor. To turn the mirror over, with its reflective side movable between its viewable and covered positions, it can be grasped at the edge opposite the hinge axis, the grasped edge can be swung out, the hinged edge can be shifted along the guides, and the grasped edge can then be swung back again. This enables the mirror side which was formerly toward the outside to rest against the sun visor and thus be covered, and vice verra. In order to counteract canting upon the displacement of the mirror, it is advantageous for the bearing pedestals to be rigidly connected to each other by a brace.
In the preferred embodiment of the invention, the mirror is developed integrally with a rear cover which also grips the mirror around its edges. In this way, the esthetic requirement for a vehicle sun visor can be taken into account, since both the color and the surface structure of the cover can be adapted to the corresponding appearance of the specific sun visor.
The rear cover is preferably provided with the hinge axis. This enables developing the hinge axis as a pin which is to be fastened to the cover or, on the other hand, enables developing the hinge axis integral with and of the same materials as the cover. The latter method is particularly suitable when the cover is a plastic injection molding, which is preferable for such a cover.
In a further development of the invention, the mirror can be arranged reversibly on a box-shaped housing which is fastened to the sun visor and the housing is provided with guide slots. This makes it possible to assemble a structural unit which includes the displacement mechanism and to apply it to a finished sun visor.
Another preferred embodiment of the invention resides in the mirror, preferably together with the housing, being swingable within a recess in the sun visor in such a manner that the mirror does not project beyond the corresponding outer surface of the sun visor, either in its covered position or in its viewable position. In this way, a pleasing appearance of the sun visor is obtained and safety interests are also taken into account because of the absence of protruding corners and edges.
As a further development, the housing may have at least one chamber adjacent an edge of the mirror containing an electric light. This result in the possibility of using the mirror in the dark.
Other objects and features of the invention are described below with reference to the accompanying drawings.
Brief Description of the Drawings
FIG. 1 shows a sun visor with a reversible mirror arranged on it;
FIG. 2 is a section along the line II--II of FIG. 1 with the mirror shown covered;
FIG. 3 is a section along the line II--II of FIG. 1 with the mirror arranged so that it is viewable;
FIG. 4 is a detail showing the mirror and the mirror housing; and
FIGS. 5 and 6 are each a section taken along the line A-B of FIG. 4, with different arrangements of the mirror.
Description of the Preferred Embodiment
A sun visor consists essentially of a generally flat sun-visor body 1 having a swivel mount 2 arranged in the vicinity of one end of its upper longitudinal edge, an outer support pin 3 which is arranged on the other end of the same longitudinal edge and which can be detachably engaged in an outer support housing (not shown) on the vehicle body, and a mirror 4 arranged on the sun-visor body. In the embodiment shown, the mirror 4 is seated within a housing 5 in which chambers 6 for electric bulbs 7 are developed on both sides of the mirror, as shown in FIG. 4.
As can be noted from FIGS. 2, 3 and 5, 6, the mirror 4 is developed integrally with a rear cover 8 which also surrounds its edges, and the mirror and cover are mounted together reversibly in the housing 5. The cover 8 has oppositely projecting pins 9, which are located at an edge region of the mirror and which together form a hinge axis. The pins are received in bearing pedestals 10 which, in their turn, are seated displaceably in guide slots 11 in the housing 5. The bearing pedestals 10 are preferably connected to each other by a brace 12. Like the housing 5, the cover 8 preferably is a plastic injection molding. It has a projection 13 formed on it in the central region of the edge opposite the hinge axis, which serves as a handle. The projection 13 has a narrowed neck portion 14, which is received in an undercut housing slot 15 which is provided on opposite inner housing-edge regions. The slot continues in a grip trough 16 which is recessed in the sun-visor body 1, since the housing 5 is preferably arranged in a trough-shaped depression 17 in the sun-visor body 1.
To swing the mirror 4 out of it covered position (see, for instance, FIG. 2) into its viewable position (see, for instance, FIG. 3), it is merely necessary to pull the projection 13 with one's finger out of the corresponding housing slot 15, and to swing it over a total of 180.degree., while at the same time pushing the hinge axis within the slotted guide in the direction toward the opposite end. This course of motion is shown in FIGS. 5 and 6.
Optionally, the visor may be provided with springs to aid in the motion of the mirror, although a particular spring arrangement is not part of this invention.
Although the present invention has been described in connection with a preferred embodiment thereof, many variations and modifications will now become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
Claims
What is claimed is:
