Description
Handle set for window and door wings with espagnolette
The Dresent invention relates to a handle set for window and door wings with an espagnolette, i.e., a movement transmitting mechanism positioned in the edge of the frame, consisting of a bearing box attachable to the frame of the window or door wing and screwable to the esDagnolette, and a sauare mandrel being pivoted within the bearing and axially fixed therein and having a handle positioned at its outer end.
Handle sets of this kind are known, e.g.. from DE-GM 88 02 929. In these known handle sets the handle is positioned detachably at the outer end of the sauare mandrel, and the handle is Dushed on tne end of the sauare mandrel only after the bearing box has been mounted or screwed on. respectively. and is fastened by means of a peg or screw. In this connection, the four-edged mandrel is inserted ,nto the bearing from the bae or the supporting side of the bearing. and leans axially against the bearing over a shoulder or collar. In case of such handle sets. the handle has to be fastened carefuliv to the square mandrel in order to keep the axial play of the square mandrel to a minimum.
It is accordingly the object of the present invention to provide a handle set which can be screwed to a wing of a window or a door as Dre-assembled unit, and in which the handle is connected with the square mandrel nondetachably, and the sauare mandrel is suooorted in the bearing without, or with only slight axial play.
According to the present invention, this object is achieved in that the bearing exhibits an abutment plane, which is staggered from the supporting plane of the bearing towards the handle side, and a cylindrical recess starting from the handle side. and that the square mandrel exhibits a plastic bush which is insertable into said recess and slightly projects from said cylindrical recess at the handle side, and that a groove is placed around the four-edged mandrel within the region of the abutment plane, said groove having inserted therein a spring supporting itself against the abutment plane.
The spring engaging into the groove of the square mandrel may be inserted with ore-stressing acting into the axial direction of the sauare mandrel so that the handle is adjacent to the plastic bush without play.
However. it is also possible to insert the spring into the groove of the square mandrel in such a way that a play of, for example, 0.1 to 0.2 mm remains.
In a preferred embodiment of the present invention the cross-section of the four-edged mandrel formed by the groove is auadriform whereby the sides of this square run parallel to the sides of the sauare mandrel, and the spring, which is formed as a leaf spring. is inserted with a pre-stressing acting radially to the axis of the square mandrel. Said leaf spring not only serves as axial fixing of the square mandrel in the bearing, but simultaneously as catch spring which marks both the closed and the open position of the square mandrel or the handle. respectively.
Further features of the present invention result from the claims.
In the following description two embodiments of the present invention are illustratea more detailed with reference to the drawings. In the drawings
Figure 1 shows a sectional view of the handle
set according to the present invention,
Figure 2 shows a top view on the bearing box,
Figure 3 shows a view on the handle from below
Figure 4 shows an enlarged view of the back side
of the bearing box according to Figure
1,
Figure 5 shows a sectional view of a handle set
similar to that according to Figure 1,
however with a modified spring.
The handle set as illustrated in Figures 1 to 4 consists of a bearing 1 and a square mandrel 3 being pivoted and axially fixed therein, at tne outer end of said mandrel a handle 2 is fastened nondetachably, particularly by means of glueing. The bearing 1 exhibits an abutment plane 10 being misaligned from the supporting plane 11 of the bearing towards the handle side, and a cylindrical recess 8 starting from the handle side. The square mandrel 3 exhibits a plastic bush 4 which is insertable into said cylindrical recess 8 and slightly projects from the cylindrical recess 8 at the handle side so that a gaD results between bearing box 1 and handle 2. In the region of the abutment plane 10 a groove 6 runs within the sauare mandrel 3.Said groove having positioned therein a spring 7 which rests against the abutment plane 10 and serves to axially fix the square mandrel 3.
As is shown in Figure 4, the spring 7 is an oblong leaf spring which, in its middle section, is supported in the groove 6 of the four-edged mandrel 3 and, at its both end regions, against the abutment plane 10 and the housing wall 12 of the bearing box 1.
As is shown in Figure 4, the cross-section of the four-edged mandrel 3, which cross-section is formed by the groove 6. is auadriform whereby the sides of the square run parallel to the sides of the square mandrel 3. The leaf spring 7 is inserted with a pre-tension acting in the radial direction of the axis 9 of square mandrel 3. The edges of the square built by the channel 6 are broken or chamfered. respectively.
Depending on the bending of the leaf spring 7 this can be more or less rigid. According to Figure 4 the supporting point of the spring 7 against the housing wall 12 is positioned further to the external side on the left hand than this is the case in the right half of the drawing. Accordingly, the spring 7 on the right side of the drawing is more rigid than that according to the left side of the drawing.
As is shown in Figure 1. the spring 7 can also be inserted with a pre-stressing acting axially to the axis 9 of the square mandrel 3 so that the square mandrel 3 is supported in bearing 1 or plastic bush 4, resDec- tively, in a manner which is free from play. The bearing box 1 consists of zinc die-casting, and the plastic bush 4 consists of a plastic material exhibiting good sliding properties and high abrasion resistance, it particularly consists of polyacetal. The plastic bush 4 is situated with its face end on an annular border of bearing 1. which border is situated at the end of the cylindrical recess 8. That part of the plastic bush 4 projecting from the bearing 1 can also be formed as rin-shaDed collar 5 being adjacent to the handle side of the bearing 1.
In order to screw the bearing 1 to the housing of the espagnolette, the bearing 1 exhibits two guide bushes 14 and 15 which project over the supporting plane 11 and the axes 16 and 17 of said bushes are in the same plane as the rotational axis 9 of the square mandrel 3.
As is shown in Figures 2 and 4. the bearing 1 is shaoed oblongly and symmetrically to its longitudinal axis 18, and the longitudinal axis 19 of handle 2 aligns in closed position with the longitudinal axis 18 of bearing 1. The Plane of the three axes 9. 16, and 17, however, with respect to the longitudinal and symmetric axis 18 of bearing 1, is misaligned towards the housing's side wall 13. This misalignment amounts to about 10% of the width cf the bearing box 1 or the handle 2, respectively. This misalignment results in the fact that in case of window or door wings oDening outward and a small mandrel dimension, i.e., in case of a small distance of axis 9 of square mandrel 3 from the outer edge of the window or door wing, the handle set. and in particular the handle 2 turned into the oDen position, do not strike against the window or door frame.
As is shown in Figure 2, cylindrical recesses 21 and 22 are provided for above guide bushes 14 and 15, which recesses are Positioned symmetrically to the longitudinal axis 18 of bearing body 1 and accomodate the heads cf the fastening screws. These cylindrical recesses 21 and 22 can be closed by caDs 24 which are mounted at the handle side on the bearing box 1 after installation. CaDs 24 are provided with ring-shaDed fittings 25 which engage into the cylindrical recesses 21 and 22. Additionally, the caDs 24 may be provided with pins 26 engaging into slots 27 of the bearing 1.
The cap 24, which is hidden bY handle 2 when this is in the closed position, may exhibit a recess 28 into which a locking gudgeon of a lock engages, which lock may be placed in the hollow space 29 of the handle 2.
According to the embodiment illustrated in Figure 5, the cross-section of the sauare mandrel 3 formed by the groove 6 is round, and tongues 7". which are bent out of an elastic washer 7'. are engaging into said groove; said tongues apply an axially acting prestress on the square mandrel 3. This elastic washer 7', which consists of thin spring steel sheet. wltn tongues 7ft only serves as axial securing device for the sauare mandrel 3. In this embodiment, a 900-position would have to be effected by means of an additional spring acting against the square surfaces of the sauare mandrel 3.
