Abstract
The mirror is connected to the vehicle by a base 5 and ball-and-socket arrangement 6. The ball is generally hollow and relatively large with respect to base 5 to allow smaller bases to be used and to allow attachment to the vehicle internally of the base. The mirror is mounted on the ball by way of a rod 9, pressure-piece 8 within the ball and held by a spring 10. The ball is formed from two parts connected together at a snap-fit 13,14. <IMAGE>
Description
A REAR-VIES MIRROR FOR MOTOR VEHICLES
The invention relates to a rear-view mirror for motor vehicles, more especially an external mirror,wherein the housing, which accommodates the mirror body, is disposed on a base by means of a ball joint, the base serving as the means for securement on the vehicle, and the ball of the ball joint, which is situated on the base and is kept hollow, is actuated from inside the vehicle via the intermediary of a pressure-piece mounted on the housing.
This pressure-piece is generally spring-loaded and ensures that there is good, adequate pressure between the ball, on the one hand, and the socket which is situated on the housing. In order to permit this pressure-piece to be assembled with its associated compression spring, these component parts have to be introduced into the hollow base.
It is obvious that such an assembly is only possible when the base has a large inside width and, in addition, the ball of the ball joint only has a comparatively small, effective diameter. However, such dimensions do not comply with the demand for the joint to have a good frictional connection and for the base to be only narrow. Large diameters are desired for the ball in order to achieve good coefficients of friction and, moreover,narrow bases which are not too bulky are desired for securement on the vehicle.
In consequence the invention seeks to provide the above mirrors so that it is possible to select a large ball for the joint and also a narrow base, whilst still permitting the mirror to be fitted together.
To achieve this object according to the invention, the upper portion of the ball, which is actuated by the pressurepiece is connectable, as an individually produced body, to the lower portion of the ball after the pressure-piece has been fitted. This connection is preferably effected by so-called clipping-together or snap-fitting An interlocking connection is provided, that.is to say, by tongue and groove means. This connection is achieved when the two portions of the ball are pressed together and produce a certain amount of resilient deformation, the two portions of the ball providing, and then also maintaining, the interlocking.It is possible for this interlocking to be discontinued by means of suitable deformations; however, the forces required therefor are far greater than the stresses which occur during operation of the mirror, so that accidental detachment is prevented.
Due to the invention, it is possible to select for the ball an effective diameter which is far greater than the width of the base. In consequence, because the ball which is kept hollow is divided, there is freedom to choose the width snd/or cavities inside the base.
The present invention will be further illustrated, by way of example, with reference to the accompanying drawing, in which the single Figure shows an external mirror for a road vehicle viewed in the direction of the mirror surface, the lower portion being shown as a sectional view.
The substantially cup-shaped housing 1, formed from plastics material serves to accommodate and adjustably support the mirror body 2 which is substantially rectangular in shape. A vertical edge of the housing 1 is provided with a substantially triangular reinforcement 3 which forms 8 ball socket 4 close to below the lower edge of the housing 1, the ball socket 4 forming with a ball 6, situated at the upper end of 8 base 5, a ball joint which serves for tne all-round adjustment of the mirror.
The base 5 and the ball 6 are kept hollow in order to permit securing means 7 to be accommodated in the base 5 for the securement of the rear-view mirror on the vehicle, as well as a pressure-piece 8. This dome-shaped pressure-piece 8 is displace ably mounted on a holder which is in the form of a rod 9 and is secured on the reinforcement 3. The pressure-piece 8 is influenced by the action of a compression spring 10 which constantly seeks to press the pressure-piece B from internally towards the ball 6 so as to maintain the frictional connection forces of the ball joint. So that such a pressing operation is possible, the rod 9 extends through a suitably formed recess 11 in the ball 6.
It is important, however, for the upper free portion of the ball 6, that is to say the section 12 which is situated on the free end of the base 5, to be individually produced and to be retained on the lower portion of the ball 6 vie the intermediary of a tongue-and-groove connection, the lower portion of the ball 6 extending directly into the actual base member. Here, an inwardly orientated, circumferential projection member 13 engages in a circumferential groove 14 in the lower portion of the ball 6. This connection is produced by a resilient deformation of the two portions of the ball 6. Due to their inherent, elastic stress, the two portions of the ball are then disposed in or against each other. Consequently, a snapfitting connection is produced which can be achieved immediately and rapidly during the assembly of the mirror.
The effective outer diameter D of the ball 6 is considerably greater than the inside width W of the base.
However, so that a suitably large pressure-piece B may be employed, the mirror is initially assembled without the lower portion of the ball 6 and the base 5 situated thereon. If, under these circumstances, the pressure-piece 8 is situated with the pressure spring 10 in the operative position shown in the drawing, the lower portion of the ball 6 is connected to the section 12 by being "clipped in positiont,whereby the mirror is then in the form shown in the drawing. In such a case, the division between the two portions of the ball 6 is preferably so selected that the section 12 has, at least substantially, a hemispherical form. The plane of division in this case extends substantially parallel to the securing surface (lower surface) of the base 5.
It is obvious that, because of the hemispherical forum of the pressure-piece 8, the inner surface of section 12, against which the pressure-piece B exclusively abuts, has to have a spherical form.
An additional feature of the invention also resides in the fact that, prior to the fitting together of the ball 6, it is also possible to secure the base 5 and/or operate the securing means 7. If, under these circumstances, the base 5 is secured on the vehicle, section 12 is attached to the housing 1.
Claims (9)
