Description

The invention relates to a fitting for a frameless pivoting window or a flap on a caravan with at least a pair of cooperating locking elements, one of which is attached to the window and the other is provided at an opening of a reveal and one of the two locking elements is movable relative to the other locking element is, as well as with an actuating lever rotatably attached to the window for the movable locking element.

Hinged windows or flaps on caravans are often equipped with several locking bolts as locking elements, which are pivoted for closing in front of tongues or similar projections, which are attached to the reveal or a reveal frame. With correspondingly wide and / or high hinged windows, several such locking element pairs are provided for secure locking. The disadvantage here is that the closing of the hinged window or the flap requires several operations to be carried out and is therefore time-consuming and cumbersome.

For a sliding window provided with a frame, it is known from German utility model 91 10 038 to provide a crank on the window and a power transmission line guided in the frame, the ends of which are coupled to the sliding window via coupling elements. The window can be raised or lowered by operating the crank.

The invention has for its object to provide a fitting for a frameless pivoting window or a flap, which significantly simplifies the closing.

In the fitting mentioned at the outset, it is provided according to the invention that the actuating lever has a crank which is connected in a rotationally fixed manner to a toothed disk and that an elongate transmission member is guided in a longitudinally displaceable manner on a rail attached to the soffit, to which the soffit-side locking element is fastened and a toothed strip is formed, whereby the toothed disk engages in the toothed bar during the actuation of the crank. It is thus possible to securely close or unlock the pivoting window at a plurality of spaced-apart locations with one handle, because the rotary movement on the crank is transmitted simultaneously by the transmission element to all movable locking elements connected to the transmission element.

The transmission member is expediently a steel band or the like which can be bent transversely to its longitudinal extent, so that tumblers can be provided not only along the horizontal, but also along the two vertical edges of the pivoting window, the transmission member being easy to follow, in particular in the corner region of the rail bent there. It is advisable to provide the steel strip with a series of holes into which each reveal element on the reveal side and the toothed strip are clipped. In order to enable the flap window to be secured in an only "gap-wide" open position, in a preferred development of the invention it is provided that each reveal element on the reveal side has an inner bolt and an outer bolt, the spacing of which intervenes between the other Locking element allowed, the rack being widened by about the distance.

Further preferred embodiments of the invention are the subject of the dependent claims.

Views of the rack from the invention of FIG. 4th

A substantially rectangular opening, not shown in detail, is cut into a reveal 1 of a caravan wall, the lower boundary of which is referred to as the upper end face 2 of the reveal 1. A circumferential frame 3 is fitted into the opening, the section of which extends along the end face 2 in FIGS. 1 and 2 is shown in section.

The frame 3 consists of an extruded profile which is screwed onto the end face 2 in a manner not shown. The light metal frame 3 has an outer, upwardly open channel 4, in which a coherent rubber strand 5 is inserted. The rubber strand 5 protrudes outwards from the channel 4 and has a molded-on sealing lip 6 which extends outwards and downwards in front of the channel. A cover 8 extends downward from the base 7 of the channel 4 and lies in front of the edge of the reveal 1 If the frame 3 is therefore screwed onto the end face 2 in a manner not shown, the channel 4 is located somewhat above and in front of the end face 2. Another channel 10, filled with thermal insulating compound, adjoins the channel 4 at the same height .

Further inward, an essentially U-shaped rail 12 is formed on the frame 3, in which a metal strip 20 is captured so as to be longitudinally displaceable. The metal band 20 is supported on two opposite, inwardly projecting shoulders 14, 16 formed from the rail 12 and extends from a narrowed upper opening of the rail 12 to form a mounting surface 22 out of it. A first, reveal-side locking element 30 is screwed onto the mounting surface 22 in an area to be explained, which can consequently move with the steel strip 20 just above the end of the rail 12.

The first tumbler element 30 has a plate 32 screwed to the steel strip in the manner mentioned and extending in the direction of the rubber cord 5, from which a solid inner bar 34, which extends parallel to the steel strip, and a solid outer bar 36, which is spaced outwardly therefrom, each rise upwards. The distance of the outer bolt 36 from the inner bolt 34 is chosen so that a hook 42 of the other window-side locking element 40 can grip between them.

The hook 42 of the window-side locking element 40 is firmly screwed via a solid web 46 at the lower edge of the inner pane 52 of a frameless swivel window 50 and projects inward so far beyond the inner surface of the inner pane 52 of the swivel window that in the closed state shown in FIG. 1 of the hinged window 50, the web 46 engages over the inner bolt 34 and the outer bolt 36 and thus the inner bolt 34 can be engaged behind by the hook 42.

The metal band 20 is displaced perpendicular to the plane of FIG. 1 within the rail 12 to such an extent that the inner bolt 34 entrained by the metal band 12 no longer blocks the path of the hook 42 in FIG. 1 to the left, that is to say in the direction of an opening movement of the pivoting window 50 , the swing window 50 is no longer closed and can be swung open. To close the hinged window 50, it is pulled against the sealing lip 6 by hand to such an extent that when the steel strip 20 is displaced in the opposite direction in the rail 12, the inner bolt blocks the hook 42.

Figures 2 and 3 show in detail the mechanism for displacing the steel strip 20 within the rail 12. In the illustrated embodiment of the invention, the pivot window 50 is at the upper edge of the reveal opposite the end face 2 by means of joints fastened to the outside and upwards. Approximately in the middle of the lower edge of the swivel window 50, which runs parallel to the end face 2, a solid joint 60 is permanently and non-rotatably fastened to the inner pane 52, on the inward-facing free end face of which a crank 62 is arranged around and parallel to the swivel window 50 End face 2 extending axis is pivotally held. A toothed disk 66, which is provided with a toothed segment 64 and is rotatable about the axis mentioned with the crank 62, is formed on the crank 62.

An elongated strip 70 is screwed onto the mounting surface 22 of the steel strip 20, onto which a toothed strip 72 which is exposed at the top is formed. As shown in FIG. 3 in particular, the arrangement of toothed strip 72 and toothed segment 64 relative to one another is selected such that the teeth of toothed segment 64 can be inserted laterally from the outside between the teeth of toothed strip 72. The center of curvature of the toothed segment 64 lies in the axis mentioned, so that when the toothed segment 64 engages in the toothed strip 72 and swivels the crank 62 in the illustration according to FIG. 3, the toothed strip 72 with steel band 20 in the rail 12 from left to right right shifted. If, on the other hand, the crank 62 is pivoted downward in the illustration according to FIG. 3, the toothed strip 72 with the steel band 20 in the rail 12 is shifted from right to left.

This makes it clear that the engagement of the hook 42 described in connection with FIG. 1 behind the inner bolt 34 by pivoting the crank 62 in the correct direction and releasing the movement path of the hook 42 to the outside by pivoting the crank 62 can be effected in the opposite direction because the reveal side locking element 30 takes part in the displacement movements of the steel strip 20.

Accordingly, if the pivoting window 50 is to be fully opened from the closed position shown in FIGS. 1 and 2, the crank 62 must be pivoted upwards so far that the hook 42 is released from the inner bolt 34 and then the crank 62 or the window 50 must be opened externally directed pressure are exerted, which causes the teeth of the toothed segment 64 to slide outwards laterally out of the spaces between the teeth of the toothed rack 72 and thus decouples the toothed disk 66 from the toothed rack 72, so that the window can be opened freely.

In order to avoid inadvertent opening of the closed pivot window 50, there is a spring-loaded pin 68 in the axis of the joint 60, which in a position of the crank 62, which corresponds to a locking of the pivot window 50, for example the position according to FIG inner stop is released within the joint 60 and protrudes outwards, as shown. To unlock the window, the locking pin 68 must therefore be pressed in with the thumb of the hand.

The first pair of locking elements 30, 40 shown in FIG. 1 is attached to the pivoting window 50 on the right when viewing FIG. 3 at a distance from the crank 62. It is of course within the scope of the invention to provide a second pair of tumbler elements to the left of the crank 62, which pair is identical in construction to the first pair of tumbler elements 30, 40. Since the steel strip 20 can be easily bent transversely to its longitudinal extent, can still further pairs of locking elements, for example on the opposite vertical edges of the pivoting window 50 and the reveal edge, which are also identical to the pair of locking elements 30, 40. All pairs of locking elements are actuated centrally by the crank 62 via the steel belt 20 simultaneously and in the same direction in the sense of opening or closing the pivoting window 50. It is understood that the rail 12 has a sufficient length in the frame 3.

Since it is often desired not to close the pivoting window 50 but only to keep it open a little, the invention also satisfies this wish. For this purpose, the toothed strip 72 according to FIG. 2 is designed with an outwardly extending width, which ensures that the toothed segment 64 engages in the toothed strip 72 even when the inner bolt 34 and the outer bolt 36 engage the hook 42 at the “gap-wide” opening of the pivoting window 50 between them. The outward widening of the toothed strip 72 is indicated at 74 in FIG. 2. In this case, the pivoting window remains open along its lower edge by a distance which is the distance between the same vertical surfaces of the equally strong inner bolts 34 and outer bolts 36. Nevertheless, the swing window 50 is securely locked even in this little open position.

Incidentally, it goes without saying that the lateral insertion of the teeth of the toothed segment 64 into the spaces between the teeth of the toothed rack 72 when the pivoting window is pulled into the closed position from a fully open position is facilitated by threading aids, for example by suitable flank shapes of the teeth can be.

The exemplary embodiment of the invention shown in FIGS. 4 to 6 differs from the above-described embodiment essentially by the omission of the frame and a simpler design of the reveal-side locking elements or the toothed strip. The window-side locking elements and the crank are the same with the corresponding components of the exemplary embodiment of the invention explained above, so that they are provided with the same reference numerals.

Again, only the lower part of the frameless pivot window 80 is shown. At the lower edge of the inner pane 82, the window-side locking elements 40 are fastened at a distance and the crank 62 is anchored with the toothed disk 64 and toothed segment 66 about an axis perpendicular to the plane of the inner pane 82.

As is particularly clearly shown in FIG. 4, the reveal side frame is reduced to a rail 90 with a U profile, the base 92 of which is screwed onto the end face 2 of the reveal 1. Between the base 92 and the end face 2 there is an elongated sealing profile 86, the inner tab 88 of which overlaps the inside of the reveal 1. The outer tab 84 of the sealing profile 86 encompasses the part of the soffit 1 adjacent to the end face 2 from the outside, a sealing lip 85 being formed on the outer tab 84, against which the pivoting window 80 bears in the illustrated closed state.

The rail 90 has two opposite side cheeks 94, 96, into which two opposite grooves are cut. In the two grooves, a steel strip 100 is guided so as to be longitudinally displaceable, which has a number of equally spaced holes, for example holes 102, 104, 106. In terms of its bending properties, the steel strip 100 corresponds to the metal strip 20. However, the steel strip 100 is flat and, unlike the metal strip 20, does not extend above the plane of the grooves.

7 to 9 consists of an essentially rectangular plate 112, from the underside of which four grippers 111, 113, 115, 117 protrude. Each gripper is provided at the free end with an inwardly projecting shoulder, which is designated 115 on the gripper 113. The shoulder 115 points to the corresponding shoulder of a gripper 111 located opposite the intended transport direction T. The grippers 111, 113 of a first pair are spaced apart from the grippers 115, 117 of the second pair in the transport direction T. As can be seen, for example, from the grippers 115 and 117 in FIG. 4, the grippers of each pair are spaced apart by a distance transversely to the transport direction T which corresponds to the width of the rail 90 on its upper side, so that when the plate 112 is placed on it Underside on the rail 90, the four grippers 111, 113, 115, 117 from the cheeks 94, 96 can protrude laterally projecting webs. The length of the grippers is chosen so that the plate 112 clipped onto the rail 90 remains slightly displaceable on the upper side of the rail 90, but the plate 112 cannot be easily removed from the rail 90.

From the underside of the plate 112 protrude elevations 114, 116 spaced in the middle between the two grippers of a pair in the transport direction T, which, when the plate 112 is placed on the rail 90, find space between the cheeks 94, 96 and rest on the steel belt 100. A projection 118, 119 projects from each elevation 114, 116, the diameter of which corresponds essentially to the clear width of one of the holes 102, 104, 106. The distance between the pins 118, 119 in the transport direction T is a multiple of the distance between adjacent holes 102, 104, 106. Therefore, the plate 112 can be clipped onto the steel strip 100, with the pins 118, 119 in two of the holes 102, 104, 106 pinching penetrate.

A plurality of spaced, parallel toothed ribs 122, 124, 126 are formed on the upper side of the plate 112, the shape of which corresponds to the teeth of the toothed strip 72. All toothed ribs open into a wall 128 which is formed along the inner edge of the plate 112 and rises above it and the toothed ribs. On the opposite outside of the plate 112, the rear toothed ribs (for example toothed rib 126) open in the transport direction into an outer wall 125 which is formed along the rear portion of the outer edge of the plate 112, rises above it and is approximately the same height as the wall 128 Approximately in the middle of the top of the plate 112 there is a central wall 123 which is approximately the same length as the outer wall 125 and is chamfered at its front edge area at 121 as an insertion aid for the toothed segment 66.

The walls 125, 123 fulfill the same function as the outer bolt 36 or the inner bolt 34, namely in that when the pivoting window is closed Tooth segment 66 passes between the walls 128 and 123 and abuts the latter. When the swivel window 80 is "gap-wide", the toothed segment 66 lies between the walls 123 and 125 and can rest against the wall 125. Because of the walls 123 and 125, the toothed strip 110 also fulfills the function of a reveal element on the reveal side.

The operation and the function of the fitting according to this embodiment of the invention are the same as those according to the example described first.

It goes without saying that the rest of the reveal-side locking elements which are not provided with toothed ribs are designed on their undersides in the same way as the plate 112. This embodiment of the invention therefore has the advantage of very easy assembly of the reveal-side locking elements and the toothed strip on the steel strip 90. Since the frame, which is usually a relatively complicated extruded profile, is omitted and replaced by the rail 90, the invention permits relatively simple retrofitting or retrofitting of pivoting windows on caravans.
