(54) LOCK STRIKER MEMBER
(71) We, REGIE NATIONALE DES
USINES RENAULT, a company incorporated according to the laws of the Republic of
France, of 92109 Boulogne-Billancourt,
France, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed to be particularly described in and by the following statement:- The present invention relates generally to a lock for example for the rear boot or luggage compartment of a motor vehicle, more particularly to a striker member for such a lock.
In many motor vehicles the rear boot or load-carrying compartment is held closed by a lock assembly comprising a lock bolt with actuating mechanism, which are mounted on the movable closure panel or boot lid, and a striker member which is secured to a transverse member of the vehicle body, inside the boot. Striker members of such previously proposed assemblies generally fall into two groups: - striker members which cannot be dismantled, being made directly by stamping or punching in the sheet metal of the body or being formed by additional members which are welded to the sheet metal member.No adjustment of the striker is possible; - dismantleable striker members which comprise an assembly of a plurality of small members such as a striker element in the form of a member which has a slot to receive the lock bolt, a set of packing members of different thicknesses, screws, washers and nuts or anchor plates. Adjustment can be effected in two or three orthogonal directions, by changing the number of packing members and by virtue of the screws having clearance in suitable slots in the sheet metal member or in the striker element.
The need for adjustment can result from 1) defective alignment of the lock bolt with the striker projection, as correct position of the retaining point, i.e. the point of which the lock bolt bears against the retaining projection of the striker member, should permit closure without play of the movable panel or lid, or 2) defective engagement, as penetration of the lock bolt behind the striker projection should be sufficient to prevent untimely opening of the bolt lid.
For the purpose of adjustment of the previously proposed striker members of the second group, either during first assembly of the vehicle or e.g. during subsequent maintenance operations, it is necessary to unscrew all the fixing screws, to interpose.
as necessary, an adjusting packing member between the striker member and its support surface, and to adjust the striker member on the screws before re-tightening the screws.
These different operations require a substantial amount of time, both for assembly, because of the number of components to be assembled, and for adjustment. In addition, it is always possible that the assembly will go out of adjustment, due for example to vibration of the vehicle on the road.
According to the invention, there is provided a striker member which in use is mounted on a first of two members which are relatively movable one with respect to the other, and which in use is co-operable with a bolt of a lock mechanism mounted on the second member, thereby to secure the first and second members relative to each other, which striker member is in one piece and is of polygonal section with pairs of oppositely disposed parallel edges whereby it is capable of assuming a plurality of adjustment positions in a mounting recess in said first member, the striker member having a plurality of striker projections cooperable selectively with said bolt according to the adjustment position of the striker member, and having means for fixing the striker member to said first member in said mounting access by a clipping action in a so selected as to take up clearance between respective one of said adjustment positions said bolt and the respective retaining striker projection in the said secured condition of the first and second members and to bring the point of contact between said bolt and the respective striker projection to a fixed pre-determined position.
The invention will now be described by way of example with reference to the accompanying drawings, in which:
Figures 1 and 2 are perspective and plan views of the striker member,
Figure 3 is a view of the striker member in section taken along line III-E in Figure A, Figure 4 shows a view in cross-section of the mounting of the striker member in a transverse member of a vehicle body, and its cosperation with a lock bolt,
Figure 5 is a plan view of the stamping of a sheet metal member for mounting the striker member, also showing the outline of the striker member relative to the stamp ing.
Figures 1 to 3 show a onepiece striker member 1 which comprises a thin body portion 2 of irregular hexagonal shape, or more precisely of triangular shape in which the apexes are truncated. It will be seen from
Figure 2 that the body portion 2 thus comprises three pairs of oppositely disposed parallel faces, one face of each pair being a long face as at 2a and the other face being shorter face as at 2b. Along the edges of the body portion 2 are disposed projecting shoulder or flange portions 3 and 4. The portions 3 are disposed on the shorter faces at 2b, while the portions 4 are disposed on the faces as at 2a. Figure 3 shows that the portions 3 and 4 project beyond the large or major faces of the body portion 2.
The striker member 1 is preferably of plastics material, being e.g. moulded, in one piece.
As shown in Figure 3, each shoulder portion 3 and 4 has a flat internal face 3s and 4q, at the body portion side, and a convex outer face 3b and 4b, each of which, approximately at its centre, is interrupted by a groove 5 and 6 substantially parallel to the plane of the body portion 2. The grooves 5 and 6 are provided for clipping the striker member onto a support sheetmetal member, as will be described below.
The right-hand portion 4, as viewed in
Figure 3, forms a striker projection and is a solid portion which, like all the portions 4, extends over the entire length of the respective face 2a of the body portion, and even therebeyond. The left-hand portion 3 as viewed in Figure 3 is a resilient portion which may be hollow as shown to increase its degree of elasticity, as it is more particularly intended forfitting the striker member 1 in place by a clipping action, by displacement of the body portion 2 in the plane thereof (as will be described below in greater detail). The portion 3 is disposed on a respective one of the truncated faces 2b of the body portion, therefore being of a length which is less than the length of the face 2a.The portions 4 which form striker projections join together externally in twos at respective surfaces 7 (Figure 2) so that the member 1 viewed in plan view (Figure 2) shows a regular hexagonal outline with parallel faces, circumscribed on the body portion 2 of the striker member.
The thickness of the portions 4 is smaller at the truncated apex faces 2b of the body portion 2, than at other positions, and the hollow portions 3 project relative to the faces 7, in the manner of a bridge which is supported by its ends as at 8 in Figure 1.
The striker member 1 therefore provides three striker projections at at 4, which are separated by as many portions 3, as shown in Figure 2 most clearly, the two operative shoulder portions 3, 4 of each pair being arranged opposite to each other and being arranged on three axes of symmetry X1,
X2, X3 of the striker member.
As can be seen from Figure 3, the portions 3 and 4 project to different extents at respective sides of the body portion 2, i.e.
each portion 4 forms two different heights of striker projections as at 4a and 4c. The striker projections 4n and 4c can be used selectively by turning the striker member 1 over.
This structure thus corresponds to two possible adjustment positions as regards engagement of the lock bolt 9 againt the striker projection 4, that is to say, adjustment of the distance by which the lock bolt 9 penetrates into the striker member towards the body portion 2 (Figure 4).
The distance between the vertical inner walls of the two opposite portions 3 and 4 of the respective pairs of the body are not equal. Thus, as shown in Figure 2, the three distances l, a2 and a3, as measured along the respective axes X1, X2 and X3, correspond to three distinct adjustment positions for alignment of the lock bolt for fixing the position of the retaining point P on the axis in question.
The choice of the lock bolt alignment position is therefore determined by the three possible perinutations of the striker member about its vertical axis of symmetry Y (Figure 3).
In Figure 2, the body portion 2 of the striker member is defined by two series of parallel lines, one series of line at 10 being broken lines. This distinction between the solid lines and the broken lines 10 represent ing the outline of the body portion, shows the difference between the distances between shoulder portions 3 and 4 (which moreover could be equal) at respective sides of the body portion, in the same cross-sectional plane (Figure 3), thus adding three other possible adjustment positions a4, a5 and a6, for alignment of the lock bolt, after the striker member 1 has been turned over (only position a4 is shown).
In total, for each of two engagement adjustments, there are three adjustments in respect of alignment, that is to say, there are six possible pairs of these two kinds of adjustment, and therefore six distinct positions of the striker member in its housing.
Figures 4 and 5 illustrate the mounting and mode of operation of the above-described arrangement.
A punching or stamping 11 in a horizontal transverse sheet-metal member 12 of the boot of a motor vehicle body is overdimensioned relative to the outside dimensions of the striker member 1 whose outlines it follows, except for the pair of operative portions 3 and 4 which are clipped by means of their oppositely disposed grooves 5 and 6 onto the edge of the sheet metal.
Thus, after the resilient portion 3 has been introduced into and centred in a corresponding recess 13 of the stamping 11, it is sufficient to press against the oppositely disposed portion 4, perpendicularly to the body portion 2, to cause the respective outside inclined surface 4b to move against the edge of the sheet-metal member 12, until the striker member 1 has been clipped in position, by the metal engaging into the groove 6. The clearance is taken up by the resilient portion 3, and only the faces 14 on respective sides of the portion 3 bear against the recess 13 to prevent the striker member from moving by the action of the lock bolt 9 during closure of the boot lid 15.
Figure 4 shows the lock bolt 9 projecting from an actuating mechanism 16 of the lock which is fixed on a movable panel or lid 15 of the boot and which is illustrated diagrammatically by dash-dotted lines. The lock bolt 9 is shown in three successive positions, a first position 9" corresponding to the position before closure, a second position at 9' corresponding to engagement against the striker member at the outside inclined surface 4b of the shoulder portion 4, and a third or closed position 9 in which the lock bolt is engaged and retained by the striker projection 4, at the contact point P.
Figure 3 shows the position P1 of the contact point, which corresponds to correct adjustment of the striker member, both as regards alignment and as regards engagement of the lock bolt 9, and adjacent positions
P2 to P6 which are produced by the five other possible combinations of adjustment
positions of the striker member; It will be understood that in general there is only a single correct adjustment position, which is fixed in space, and that the purpose of moving the striker member is to chose between the six positions P1 to P6 to bring the point
of contact P of the lock bolt 9 to the cor- rect position. In this case in Figure 3, this is point P1.
In practice, it is recommended that the spacing distances in the grid P1 to P6 should be as follows: 2.5 millimeters between each two alignment position (horizontal) and 5 millimeters between the two engagement positions (vertical). but these values only indicate a general order of magnitude.
Referring to Figure 5, it will be seen that there is sufficient clearance 17 between the stamping 11 and the striker member 1 for movement of the striker member, outside of the portions 3 and 4 which are provided to secure insertion of the striker member into position.
Indeed, insertion of the striker member into its operative position should not be impeded by and the existence of other adjustment posi- tions, and the variations. in the space occupied by the striker member after each circular permutation of the striker member must be foreseen in order to avoid any impeding of adjustment.
In an alternative form, the striker member 1 could be of a quadrangular shape, without departing from the scope of the invention as defined by the appended claims.
In that case there would only be four different adjustment positions. In the same manner, it would be possible to extend the possibilities of adjustment, e.g. with an octagonal striker member, operating on the same principle, or with a striker member of other polygonal shape with parallel faces.
It will be apparent that the above-described striker member may readily be used in combination with a lock of conventional type.
Apart from the fact that the one-piece striker member as described above can advantageously be manufactured of plastics material and rapidly mounted after having been tried in different adjustment positions, the striker member which is mouted in this way cannot then generally go out of adjust ment, being held firmly in its suitable stamping, without any other fixing member. This striker member is therefore highly suitable for mass production and mass assembly, thus substantially reducing production costs.
