Definitions

• the invention relates to a locking device for a wing of a vertical sliding window that is vertically slidable relative to a fixed frame according to the preamble of claim 1.
• Such locking devices are already known, for example from US 5244238 or US 5791700.
• the locking devices known from this consist of a drive rod drive, which is arranged in an upper horizontally extending spar of a wing.
• the wing engages with latches on the one hand in lateral guides which are attached to the fixed frame, on the other hand pivotable latch members are provided on the connecting rods which interact with latch engagements in a closed position of the wing.
• the locking interlocks are mounted in a lower, horizontal spar of an upper wing or a fixed post of the frame. This results in three possible switching positions: in a first switching position the sash can be fixed relative to the frame and possibly a second sash.
• the latches In a second switching position, the latches, which can be pivoted via the drive rod, are moved out of the latching engagements, so that the sash can be displaced vertically. Finally, in a third switch position, the latches engaging laterally in the guides are moved out of the latter and the wing can be pivoted about a lower horizontal axis while maintaining a lower bearing in the guides.
• the latches engaging in the lateral guides are connected to the drive rod by means of an idle stroke, so that the latches are carried along only after this stroke has been exceeded. To ensure the engagement of the bolts, these are spring-loaded via springs in the direction of engagement.
• the object of the invention is therefore to provide a locking device which is simple in construction and inexpensive to manufacture. This object is essentially achieved with the features of the characterizing part of claim 1.
• the proposed solution has the effect that the locking device can be attached to the wing in a substantially concealed manner, since it is attached on the back — that is, not visible to the user.
• the assembly of the locking device is very simple since only one groove has to be provided for receiving the drive rod drive.
• the type of closure of the locking device causes a very secure intervention, so that manipulation, for example by a burglar, is at least made more difficult.
• 1 is an interior view of a window with two sashes
• FIG. 1 shows a vertical sliding window 10 consisting of a fixed frame 12, an upper window wing 20 and a lower window wing 30.
• the frame 12 and the wings 20 and 30 can be made from different materials, for example extruded aluminum profile, plastic or wood or from composite materials of the aforementioned.
• the wings 20 ⁇ and 30 are provided with transparent panes made of glass or plastic.
• the frame 12 also has the lateral guides 14 and 16, in which the lower wing 30 is guided vertically.
• the upper wing 20 is also slidably guided in further guides (not shown here).
• Insert parts 15 and 17 are secured in the upper section of the guides 14, 16.
• Each insert part 15, 17 is provided with a retaining plate, under which the rod tips 40 and 41, which can be moved back and forth, can be ascertained when the lower wing 30 has been completely lowered.
• a handle 32 is provided on the lower wing 30 in order to operate the closing device of the window 10, as described below.
• the lower wing has bearing pins 18, 19, to which known relief devices can be assigned, which are guided displaceably in the channels 14, 16.
• the bearing pins 18, 19 remain in engagement and hold the wing 30 on the frame 12 even when the locking device has been brought into the open position and the lower wing has been pivoted inwards, for example for cleaning.
• FIG. 2 it can be seen that the upper, horizontally extending spar 31 of the wing 30 lies in the closed position of the window 10 next to the lower, horizontally extending spar 45 of the wing 20.
• a locking device 46 for fixing the wing 30 to the frame 12 or the wing 20 is attached to the mutually facing sides of the spars 31 or 45.
• a latch engagement 47 is provided, while a connecting rod fitting 48 is provided in a stepped groove 49 on the spar 31.
• a mushroom-shaped pin 51 is fastened to the drive rod 50, which extends through an elongated hole of a faceplate 52 covering the groove 49 and cooperates with the locking engagement 47.
• the pin 51 is provided at its end 53 with a widened head 54 and has a shaft or section 55 lying behind it and reduced in diameter compared to the head 54. Its diameter 56 is matched to the distance 57 that the webs 58, 59 have from one another.
• the webs 58, 59 of the locking engagement 47 form an undercut, so that the locking engagement 47 is essentially an inverted ⁇ (omega) -shaped profile piece.
• the webs 61, 62 protruding from the base plate 60 in a U-shape are in turn spaced so far apart that the widened head 54 of the pin 51 can retract.
• the latch engagement 47 encompasses the pin 51 in the region of the waisted section 55 and prevents it from escaping from the lock in an axial direction of the pin 51.
• the bolt engagement 47 in the region of the lateral opening of the bolt slot 63 is provided with run-in bevels 64, 65 both along the webs 58, 59 and also the webs 61 and 62. It is thereby achieved that the wing 30 is moved in the direction of the lower horizontally extending frame leg when locked via the connecting rod fitting 48 and thus here
• seals between the wing 30 and the frame 12 take effect.
• the latch engagement 47 is also provided along the webs 58, 59 with run-in bevels 66 which act perpendicular to the base plate 60 and in the axial direction of the pin 51. This causes the wing spar 31 to be pulled toward the wing spar 45 when the pin 51 moves in the direction 67.
• seals of the wings 20, 30 provided here can also be pressed onto the respective other spar of the wing 30, 20 lying next to them. On the.
• the locking slot 63 of the locking engagement 47 has an inclined course in the direction of displacement of the pin 51 and the locking slot 63 is inclined downward in the direction of insertion of the pin 51 ,
• the entry slopes 64, 65, 66 are provided over a large part of the length of the bolt engagement 47 and are accordingly flatter. As a result, however, the bolt engagement 47 may no longer be symmetrical, as is shown, for example, in FIG. 4.
• FIG. 5 of the drawing shows the drive rod drive 71 for the drive rod fitting 48, in which two drive rods 73 and 74 which can be displaced in opposite directions are guided in a housing 72.
• the drive rod 73 has a toothing section 75 on its one long side with a relatively fine toothing structure, while it is provided on the longitudinal side facing away from it with a second toothing section 76 which has a relatively coarse toothing structure.
• the drive rod 74 is also provided at its end projecting into the housing 72 with a toothed section 77 which has a fine toothing.
• the toothed sections 75 and 76 are located on the drive rod 73 in one and the same length section.
• the center distance, which is selected by the two pinions 8a and 78b, is advantageous in such a way that the toothed sections 75 and 77 are divided by half a tooth pitch comb against each other. This results in optimal engagement and power transmission ratios of the pinions 78a and 78b with the toothed sections 75 and 77.
• a drive gear 79 is in permanent engagement, which is likewise rotatably mounted in the housing 72. It has a pitch circle radius that is a multiple, for example three to four times larger than the pitch circle radius of the pinions 78a and 78b.
• Drive gear 79 is equipped with three teeth and extends for example over an angular range of 90 °.
• the drive gear 79 by rotating the drive gear 79 by 90 °, for example with the aid of a square mandrel of the handle 32 engaging in a driving square, the drive rod 73 has only three tooth gaps
• Gear section 76 can be moved over their entire adjustment path. With the help of the toothed sections 75 and 77 and the pinions 78a and 78b meshing therewith, a corresponding displacement movement in the opposite direction to the drive rod 73 is then also imparted to the drive rod 74.
• FIG. 5 also shows an adjacent connecting rod component 81 which can be coupled to the connecting rod drive 71 and which has a faceplate 82 and a connecting rod 50. Together with another - not shown here - but designed according to the connecting rod component 81
• the espagnolette drive 71 forms the espagnolette fitting 48.
• the pin 51 is fastened to the espagnolette rod of the espagnolette component 81 and extends through an elongated hole 84 of the faceplate 82.
• the coupling of the espagnolette component 81 to the espagnolette drive 71 takes place via fine toothing on the outside of the espagnolette 50 Fine toothing 85 of the drive rod drive 71 can be assigned.
• the drive rod component 81 can be adapted to the dimensions of the wing 30.
• connecting rod component 81 is only provided at one end of the connecting rod drive 71 in FIG. 3, corresponding connecting rod fitting components 81 are coupled to the window 10 shown in FIG. 1 on both sides of the transmission 71.
• the end section of the drive rod component 81 is shown with a faceplate (FIG. 6) and without a faceplate (FIG. 7).
• the faceplate 82 is provided at its end with an angle piece 90, which is used for bearing against the folded surface of the wing corner of the wing 30.
• the drive rod component 81 can be aligned in a simple manner on the wing 30.
• the drive rod 50 is guided under the faceplate 52.
• the faceplate 52 is penetrating through holes 91
• the guide piece 92 In addition to supporting the faceplate 52, the guide piece 92 also serves to guide the bolt 93 which projects beyond the outer surface of the angle piece 90.
• the bolt 93 is acted upon by a spring 94 in the direction of the angle piece 90, the spring 94 being supported on the guide piece 92.
• the guide piece 92 forms a cross-sectionally approximately U-shaped guide for the bolt 93, so that it is guided along the faceplate 52 with little friction and without tilting.
• the bolt 93 is provided with an extension piece 95, through which the guide surfaces of the bolt 93 are extended on the one hand and on the other hand a pin 96 provided on the extension piece 95 can engage an elongated hole 97 of the drive rod 50.
• the latch 93 is also profiled at its end in a substantially U-shaped manner and here has a groove 98 at its end.
• the bolt 93 On its upper side assigned to the faceplate 52, the bolt 93 is provided with a U-shaped guide 99, into which the drive rod 50 engages with a tapered section 00.
• the functioning of the connecting rod fitting 48 results from this as follows: In a first switching position - the closed position according to FIG. 1 - the bolt 93 is in the position shown in FIG. 6 under the action of the spring 94 and holds the wing 30 in a plane-parallel position to the wing 20. At the same time, the drive rod 50 is in its End position shifted, in which the tip 101 shown in FIG. 7 dips into a recess in the guide 14, 16. This prevents a vertical displacement of the wing 30.
• the pins 51 are also in engagement with the locking engagement 47, so that the wing 30 is pressed against the wing 20 and the frame 12.
• the tip 101 of the drive rod 50 is first moved out of the recesses in the guides 14, 16 (not shown here), so that the wing 30 is held in the guides 14, 16 by the bolt 93 is and can be moved in the vertical direction.
• the locking engagement 47 is preferably made in accordance with FIG. 3 in a recess 103 of the wing 20 and at least on one side of the recess 103 a clearance directed in the direction of displacement of the wing 30 either on the locking engagement 47 or on the recess 10 is provided. This ensures that the pin 51 can be moved past the corresponding spar 45 of the wing 20 when the wing 20 or 30 is displaced.
• the drive rods 50 and 73 or 74 have the same construction, i.e. be formed in one piece. Then the length of the drive rod drive 71 must be adapted to the wing dimensions.
• the bolt 93 is rigidly articulated on the drive rod 50.
• the unlocking then takes place in two stages, the bolt 93 being partially moved out of the guide 14, 16 in the first stage, but remaining in engagement to the extent that the guidance of the wing 30 remains guaranteed.
• the bolt 93 is then completely guided out of the guide 14, 16 and the wing 30 can be pivoted about the lower bolts 19.
• the steps correspond to two partial strokes of the drive rod 50 and thus two partial pivoting movements, for example 45 ° and 90 ° pivoting movements of the operating lever 32.
