Definitions

  • the present invention concerns a mirror assembly for a vehicle, in particular for a commercial vehicle.
  • the support arm of rearview mirrors in commercial vehicles is commonly extended forward from the chassis at an essentially horizontal level when the mirror head hangs downward from the forward end of a support arm, they are known as “horn-mirrors,” especially when applied to buses.
  • Horn-mirrors provide better aerodynamics and simple fabrication as well as an advantageous field of view which encompasses a wide arc.
  • this zone normally covers a span from the ground level to about 2 meters above, the mirror must be adjusted as to height for the protection of both mirror and persons as may be waiting within a said safety zone.
  • EP 0 895 897 B1 proposes a single hinge attachment so that the mirror can be swiveled about a single horizontal axis, transverse to the direction of vehicle travel to move from its operational position in which the mirror is at least partially within the limits of the safety zone. Following the swiveling, the mirror would find itself in a position of no harm, and above the safety zone limits.
  • EP 0 895 897 B1 Since the mirror presents a danger of impact, both in forward and reverse travel, it becomes necessary, that the hinge of EP 0 895 897 B1 be capable of swinging in two directions of rotation, in order to protect persons in the safety zone from severe mirror impact. For example, upon a bus start-up from a bus-stop or during a backward maneuver. Likewise, the mirror must remain fixed in position of operation during normal travel, even when subjected at times to shaking and to strong wind forces. In such a case, EP 0 895 897 B1 proposes the use of friction fittings.
  • Hinges which permit swinging in both directions, and enable a simultaneous attainment of a fixed position are expensive.
  • an object of the present invention is to enable a stable securement of a vehicle mirror in its operational position and, at the same time, to assure a pivoting about an axis allowing two directions of rotation.
  • the above objective is accomplished in accordance with the present invention by providing a mirror assembly having a support arm, a mirror head, and two hinges connecting the support arm and the mirror head.
  • the first hinge allows a pivoting of the mirror head about its axle of rotation only in one direction
  • the second hinge permits a pivoting of the mirror head about its axle of rotation only in a second direction of rotation, which is opposite to the first.
  • each hinge pivots only in one direction.
  • the first and/or second hinge may incorporate a detent which limits rotation in either the first or the second direction. Such a detent can, for example, be made mechanically or be provided with a friction fit.
  • a desired second detent can also be the detent inherent in the other hinge arrangement.
  • the large lever arms, which result therefrom, assure, with relatively small support forces, sufficiently high resistance torques. In this way, completion of a pivoting opposite to the allowable direction of turning is provided.
  • the first and/or second hinge can include a torsion spring.
  • the springs in a constructive, simple, and economical manner provide a pivoting in the allowable direction and otherwise affix the mirror head securely in its operational position. Further, the springs allow the mirror head to return accurately to its operational position following a safety displacement.
  • the hinge connection between the mirror head and the carrier arm is released.
  • the axis of the first hinge prevents a further pivoting about the axis of the second hinge counter to the second rotational direction beyond the limited operational positioning.
  • the connection of the first hinge releases itself.
  • the support arm and/or the head of the mirror can be enhanced with a bearing structure, preferably of metal construction. If this is coated, for example, with a material, such as plastic, and the coating can be applied by spraying, the result is a light, aerodynamically favorable, and uniformly stable assembly of the mirror, and vibration of the mirror is reduced.
  • the first and/or the second hinge can be hingedly and reliably attached to this structure.
  • the support arm comprises a first and a second part. Between the said first and second support arm part, a third hinge is present, the axis of rotation of which extends itself vertically during the mounting of the mirror. This allows an additional pivot direction of the mirror assembly to the side or to the front of the vehicle.
  • the overall dimensioning allows an advantageous reduction of length for, as an example, loading on a ship, parking, or the like. This extra pivoting can be effected by a motor, or may be manual.
  • the mirror head is usually an elongated structure having a first end of the mirror head pointing towards the vehicle and a second end pointing away from the vehicle.
  • either the first or second hinge is attached to the mirror head at a position between the first end of the mirror head and the second end of the mirror head.
  • This arrangement reduces the space required for the mirror head upon pivoting. Due to this placement of the hinges, the mirror head acts, in the case of a pivoting in the first direction of rotation, a weight compensation and generates an inherent torque about the first axle of rotation because of gravity. In this manner a pivoting in the first direction of rotation at the constructively identical first and second hinges requires a lesser release torque. Therefore, the first hinge is already released upon small torques, while the second hinge is only released at higher torques, and thus withstands torques induced by wind forces, for example.
  • FIG. 1 is a side elevation illustrating a commercial vehicle with a mirror assembly in accordance with the present invention.
  • FIG. 2 is a side elevation illustrating a mirror assembly in accord with an embodiment of the present invention illustrating the operational position (solid line) and two deviate positions (dotted line);
  • FIGS. 3A to 3 C are side views illustrating the carrier arm of the mirror assembly in the position indicated in FIG. 2 ;
  • FIG. 4 is an enlarged view illustrating a hinge and detent according to the invention.
  • a mirror assembly designated generally as A, in accord with the present invention is illustrated installed on a vehicle.
  • the mirror assembly includes a support arm 1 and a mirror head 2 .
  • Mirror head 2 of the assembly is illustrated in a position which has not been pivoted, and at least partially extends into safety zone 6 above the ground. Since mirror head 2 , in accordance with the invention, is pivotal in alternate positions above the safety zone, damage is avoided even in the case of an impact against an obstruction within the safety zone. Especially traumatic damage to persons, who are within the said safety zone, such as, bus passengers, can be avoided.
  • FIG. 2 illustrates, in a side profile view, a mirror assembly in accordance with an embodiment of the present invention in an operating condition (solid lines) and two alternate positions (dotted lines).
  • the mirror head comprises a first hinge 3 having a first axle 31 of rotation and a second hinge 4 having a second axle 41 of rotation.
  • the mirror head 2 is pivotal about the first axle 31 of rotation in a first direction A and about the second axle 41 of rotation in a second direction B.
  • the support arm 1 encompasses a bearing structure 14 , preferably made of metal and an aerodynamic coating 13 , preferably of plastic.
  • the support arm as can best be seen in FIG. 3 , is designed in two parts. A first part 11 and a second part 12 are connected by means of a hinge 5 having an axle 51 of rotation which extends vertically when the mirror head is mounted. In this way, a pivoting of the mirror assembly laterally or to the front of the vehicle is provided.
  • the mirror head 2 includes a carrier arm 24 ( FIG. 3A ), preferably made of metal, and an aerodynamic coating 25 , such as a plastic.
  • a first mirror 21 can be adjusted by manual or motorized means in the mirror head 2 .
  • a second mirror 22 and a third mirror 23 are provided, which function as a main mirror, as a wide-scope mirror, i.e., for blind-spot surveillance.
  • the support arm 14 and the mirror head are attached together by means of the first and second hinge 3 and 4 .
  • first and second hinge 3 and 4 For the sake of clarity, in these illustrations, only carrier arm 24 of support arm and carrier arm 24 attached to mirror head 2 is presented.
  • FIG. 3A shows the mirror assembly in its operational position.
  • the carrier arm 24 holds by friction to the rotational axles 31 , 41 of the first and second hinges 3 , 4 by frictional engagement.
  • the connection can be carried out by means of friction mating or flexibly projected parts, and the like.
  • axles 31 , 41 of rotation are snapped into or onto respective hinge 3 and 4 , i. e. carrier arm 24 of mirror head 2 frictionally grips axles 31 , 41 of rotation.
  • Hinges 3 , 4 include, respectively, a torsion spring, for example, possibly a characteristically shaped steel spring.
  • the end of the spring is rigidly fixed to the carrier arm and its second end attached at frictionally engaged mirror head 2 on carrier arm 24 . In this way, a resistance to the pivoting is provided.
  • the spring can be fixed rigidly with the carrier arm 24 of the mirror head 2 and support itself in snapped-in mirror head 2 on carrier arm 24 of the support arm 14 .
  • a detent 44 provides a mechanism by which carrier arm 24 temporarily stays in place relative to the hinge until it is released by force.
  • hinge slot 46 narrows to a throat 48 reduced in comparison to axles 31 , 41 , so that the axles snap in and out of the throat. While snapped in the throat, the axles are frictionally gripped and held in place until released by snapping out.
  • the two springs also fix the mirror head in its operating position. Since the axle rotation of the respective other hinge, acting as part of the detent, prevents a pivoting counter to the desired direction of rotation, it is possible that the hinge can be constructed very simply and robustly by means of the springs. As a whole, the coaction of the two hinges 3 , 4 , the torsion springs, which provide resistance to undesired pivoting, the axles 31 , 41 of rotation, which function as a detent, and the self-engaged locking of the axle 31 , 41 of rotation, enables a constructively simple and secure fixation of the mirror head 2 in its operational position. Nevertheless the mirror head 2 can be released from this position by an impact due to collision, after which the mirror head assumes one of its alternate positions.
  • mirror head 2 is an elongated structure and in operational position of the mirror assembly has a first end 15 a pointing towards the vehicle and a second end 15 b pointing away from the vehicle.
  • First hinge 3 is attached to a mirror head 2 between first and second ends 15 a, 15 b of the mirror head.
  • the second hinge 4 is attached to first end of the mirror head 2 . Due to this placement of the hinges 3 , 4 , mirror head 2 and carrier arm 24 , respectively, acts as a weight compensation and generate inherent torque about the first axle 31 of rotation, in the case of a pivoting in the first direction of rotation A. In this manner, pivoting in first direction of rotation A at constructively equal first and second hinge 3 , 4 , requires a lesser release torque.
  • first and second hinges 3 , 4 can advantageously be built like one another, so that first hinge 3 is already released upon small torques, while second hinge 4 only releases at higher torques, and thus withstands, e. g., torques induced by wind forces.
  • mirror head 2 can be built as a two-piece structure, wherein the both parts can commonly be pivoted around second hinge 4 and only a forward part can rotate about first hinge 3 . If one examines FIG. 3C , in such a case, reference number 2 designates the forward mirror head part, and reference number 24 another mirror head part. Both parts being capable in common of pivoting about, in this case, the non-releasable second hinge 4 in rotation direction B.
  • the forward part is capable of pivoting about an non-releasable rotational hinge designated with 3 ′. Also, the kinematical turning, i.e. common pivoting in first direction A and separate pivoting of the forward part in the second rotational direction is possible
