It can be shifted with a sliding movement into a transfer position between sliding and braking, and has at least one braked position. The slide has a plug section (40), and two longitudinal notches, with a gap between them, taken up by a web section extending axially by a multiple of its width. The plug section rides in a guide rail (15) between a rod section (11a,11b,11ab) and the two edge flanges of the rail. One end is coupled to a link (70) and the other end is at a gap from the axis of the door panel or window pane at the door/window frame.

Description

The invention relates to a locking or Ausstellvorrichtung according to the introductory words of claim 1, in particular also a Gleiterbauteil for use in fitting technology. The locking device achieved in the installed state to set a (desired) opening angle of a wing of windows or doors. This is done with a, by a handle in at least two positions movable, concealed in a fitting groove of the casement arranged actuating linkage (in the installed state). The slider component has a fuselage section slidable in a guide rail, which can be attached between a rod section and two edge flanges of the guide rail and can be coupled to one end of a link. The other end of the link is hinged at a distance from a - defined by hinges of the wing - wing axis to a frame (rotatably arranged).

From the DE-C 195 16 588 (Weidtmann ) is a locking device for wings accessible to the skilled person, which has a slider member, which is designated there with 50, see. Figures 3 and 5 . 6 the local revelation. With a drive rail, an intermediate rail is moved up and down, which is biased by a spring force and has a toothing, which engages in a counter toothing on the slider member to lock the slider member in position. If the drive rail continues to move and releases the contact of the upwardly directed deformation against downward-oriented projections, the spring bias can push the intermediate rail downwards again and release the gear engagement. The existing lateral guide grooves, in which lateral webs of a C-profile form engage, guide said slider member in the longitudinal direction. A very similar oriented leadership is also found in the EP-A 1 111 174 (Winkhaus ). Again, the lateral grooves of even greater width and are guided by a web engagement in the longitudinal direction. The grooves are also provided in a slider member and below in the C-profile rail is a controlling drive rail 23 provided there for height control.

The invention is concerned with the focus with an element of a complex device, which is not shown separately and extensively, only a schematic representation of such a locking or Ausstelleinrichtung with a scissor arm and a C-shaped rail is in the FIGS. 1 . 5 and 6 shown. This is referred to insofar.

It should be possible as an object improved braking and locking by axial movement of a push rod. This by a locking or Ausstellvorrichtung for the fitting technology (of wings of windows), in particular by appropriate training of a Gleiterbauteils in use in the locking device.

The problem is solved with claim 1 or 23.

The slider as a "slider member" is received in the preferred C-shaped rail as a guide rail and has certain properties due to its shapes. A bottom of the guide rail has in its longitudinal direction after a predetermined pitch arranged longitudinal window (graduation measure), which are spaced from each other by floor webs. The rod section has over the same pitch distributed over its length top depressions (depressions) whose lower side formations depending on the relative position of rod section relative to the ground engage in the bottom window or sit on the bottom webs.

A clear height between the bottom webs and the underside of the edge flanges of the guide rail and a total height of the rod portion in the region of the formations and the height of shoulder surfaces on the body portion of the Gleiterbauteils are matched: When sliding the moldings on the floor webs sits the Gleiterbauteil with its shoulder surfaces on the Edge flanges of the guide rail firmly. An improved braking or detection results in this way.

The slider component is elongated and consists of a large base section, in which two notches are inserted from above. The notches have an axially constant distance. Between the notches, a bridge forms, which extends in the height direction. This web is used to be used between two inner edges or such edges of the guide rail and guided, preferably in C-shaped rail.

Mechanical braking forces are additionally and preferably applied in the notches, by engaging wedge-shaped protruding, in particular down, directed to the bottom of the base portion web portions of the C-shaped rail (claim 21) when the slider is pushed by the push rod upwards.

The sliding member has a greater length than width and height. It is "elongated" trained. The width is narrow, compared to the long one.

The notch shape does not necessarily have to be pointed at the bottom (claim 12), but a V-shaped notch shape is preferred in which a slight rounding occurs at the bottom and two walls are formed between which a respective web section engages from above from the C-rail , The notches extend longitudinally (claim 3 or 14) but are together narrower than the width of the slider member.

Preferably, the V-shaped aligned walls are formed so that a wall is oriented substantially perpendicular and a more inclined relative to the vertical (claim 22).

Substantially in the middle of the axial extension there is an opening, for example a hole or a recess in the plastic, through which a pin is plugged, which serves as a metallic retaining pin for mounting a linkage section (a brake or Ausstellarms example). This is rotatable in the recording, or hinged at the upper end of the pin (claim 11).

By engaging the longitudinal webs (claim 2) in the notches of the base portion of the slider is guided, is movable in the longitudinal direction, but is accurately placed within the rail and can take on its (axial) longitudinal movement at different positions of its longitudinal stroke a sliding state, on a longer portion, a transitional position from a sliding to a braking position and a braking position as such, controlled from its underside, from which it is pressed (caused by) via a control rail or lowered to release the braking force.

FIG. 1 illustrates a non-braking position of the slider G, wherein a rising edge of a suppression 11 a immediately before a web 17 a, for further movement into the braking position after FIG. 1a ,

The function of the slider is in the position of FIG. 1 , illustrated in the sectional view of FIG. 2 especially clear. It has a preferably made of plastic, as a plastically deformable material, formed body portion 40, in which - seen in section - two longitudinal notches 41,42 are introduced, which are provided with the inner distance b1. Each of these notches has a substantially vertically oriented wall 41.2 or 42.2 and a more inclined wall 41.1 or 42.1.

The two vertical walls 41.2 and 42.2 delimit a web 40a, which rises and preferably protrudes from the top of the profile 15 through a through opening 15e (as a gap). The web 40a may centrally have a further opening 50 through which a pin 60 is inserted, to which a scissor arm 70 is rotatably articulated, wherein the pin 60 is formed on the upper side in the section 61 tapers.

On the C-shaped rail 15, two horizontal web portions and two vertically, wedge-shaped and downwardly directed web portions 15a, 15a 'and 15b, 15b' are provided at the top. The latter vertically aligned portions engage in the notches 41,42 and guide the slider in its longitudinal movement.

A rail portion 11 is placed below the slider G touching on its underside 40b and can exert forces on the slider by means of recesses and depressions controlled via its upper side, as shown in the following figures.

The distance of the vertical walls 41.2 and 42.2 corresponds to b1, which distance is smaller than the total width b of the slider, which in turn is slightly narrower in its overall width than the space within the acting as a housing C-profile 15 with its side walls 15c, 15d.

The length I of the slider is substantially greater than the width b, in particular more than four times as large. The height is determined by the upstanding web portion 40a, which is slightly smaller than the width and substantially lower than the length I. In the specific example, the height is only between 15% to 20% of the length.

On the web portion 40a, a substantially parallelepiped attachment 40a 'can be mounted substantially centrally, which is provided in the region of the bore 50 and is larger in area than this.

The rail 11 lifts the slider G with its body 40, wherein the inclined wall 41.1 and 42.1 of the respective notch is applied directly to the projecting wedge-shaped web portion 15a 'and 15b' and the associated gap is reduced to zero. Such a gap is in the non-adjacent state in FIG. 4 illustrated, and with reference numerals S.1 and S.2 for the respective notch illustrated. In FIG. 2 this gap has become zero, in the braking position with the forces acting F ₁ , F ₂ , F ₁ 'and F ₂ '.

The surfaces 42.1 and 41.1 transmit normal forces to the center. By lifting F _{0 of} the slider, the force is increased and thus also the frictional forces or braking forces at the point of contact of the two surfaces or the respective surface pair of the respective notch. A saddle can be placed over the center bar and protrude into both columns, to convey the braking and holding forces.

Preferably, the walls of a respective notch, ie the walls 41.1 and 41.2 on the one hand or the walls 42.1 and 42.2 have an angle between 20 ° and 40 °, essentially occupied by 30 °, between them. Preferably, the downwardly projecting web 15a 'and 15b' is formed at such an angle.

The resulting force and the amount of increase for braking or holding are by the cross-hatched areas 41 a, 41 b in FIG. 3 clarified. Formation 11a sits on the web 17a.

By the wedge shape, the C-profile 15 is pressed in the upper region to the center (on the vertical flanks 15c, 15d, which are used as a bending distance m) to the vertical surface portions 41.2 and 42.2 for abutment with the vertical wall portions of the downwardly projecting webs to be pressed, which limits the deformation of the C-rail. Due to the frictional engagement, the braking effect is present and the slider can absorb displacement forces in the longitudinal direction (and block movement).

The rail 11 is provided with a number of elevations (recesses) 11 a, 11 ab and 11 b transverse to the longitudinal axis, which have a pitch. The pitch corresponds to the adjustment, wherein the pitch corresponds to openings 16a, 16b in the bottom 15f of the C-profile 15. The pitch T is dimensioned (graduation size) so that the standard thrusts of transmissions can be used and inaccuracies in the assembly can be compensated. The length of a breakthrough 16a simultaneously compensates for different transmission strokes, reference being made to the application which the FIGS. 7 and 8 for a wing F with profile 2, a frame 1, hinges 3, a handle 4 and a central lock 5 show, applied here with a stay arm 70 a Ausstellanordnung 6, which in different angular positions after FIG. 8 is clarified. In these positions, locking positions, displacement positions and braking positions can be used.

The adjustment can be defined at 180 ° rotary handle or at 90 ° rotary handle (actuation). A maximum adjustment results at 180 °, at 90 ° results in a division of ½. The division of the rail 15 may correspond to the adjustment.

A function of detection is described as follows. When the handle 4 is actuated, the rail 11 shifts. With a thickening or molding 11a, 11b, corresponding to the pitch T, it moves in its longitudinal movement against residual webs 17a, 17b, between the recesses 16a, 16b. About a arranged there slope, the rail is raised and pushes the sliding member G with its body 40 upwards in the direction of the opening 15e of the C-profile. A plastic deformation of the slider, which is preferably made of plastic, forms a tension, the C-profile is stretched and reaches a clamping action.

The length I of the slider G or its trunk 40 is significantly longer than a respective recess, which results in a molding 11 a or 11 b in the rail 11. Thus, clamping is possible in any position without the slider being received in its entirety by one of these indentations (seen from the top).

The release of the fixed position is achieved by turning back the handle 4. The rail elevations 11a, 11b neither drive into the recesses 16a, 16b of the C-shaped rail 15 to rotatably control the wing F with its frame 2 again. The intermediate portion 11ab, located between the protrusions 11a, 11b, comes to lie on the web 17 and determines a non-braking position (release position).

It proposes a slider component for a locking device made of plastic or a plastically deformable other material, with a greater length (I) than width (b), and for use in the fitting area in a locking device or a display device (6), in particular with displacement state, transition position from sliding position to braking position and at least one braking position. The slider has a base portion (40) and two longitudinally extending notches (41, 42) spaced from each other by a distance (b1). The distance (b1) is occupied by a web portion (40a) which extends over a multiple of its width (b1) in the axial direction.
