Abstract

Locking arrangement for the inner frame of a window, the pivoting part 2 of which, which comprises a handle 6, is fastened to the edge of the frame 1 by means of a pivot pin 5, and the counter-piece 12 of which is fastened to the edge of the case 9. The pivoting part 2 is made from two elements 6, 8 fastened to one another. By means of the grip 6, which is mounted pivotably on a fastening member 4 in the frame 1, an engagement member 8 is moved, which is fastened movably thereon and can, in the open position of the grip 6, be connected to the hook 13 formed in the counter-piece 12. When the grip 6 is pivoted into the closed position, the engagement member 8 reduces the gap between the frame 1 and the case 9 and clamps the seal 17 between them, which seal seals the gap between the case 9 and the frame 1. A plane located in the closed position of the engagement member 8 runs inside a pivot point formed by the pivot pin 5 of the grip 6, thus achieving stable locking.

Description

82969

The invention relates to a window inner frame locking device, the pivoting part of which comprising a handle is fixed to the edge of the frame by means of a pivot shaft, and the counterpart of which is fixed to the edge of the frame, in which the locking device of a fastened element, from which a handle rotatably mounted on the fastening member 10 in the frame is moved by a gripper movably attached thereto, which in the open position of the handle can be placed in connection with a nail formed on the mating piece.

As is known, the most common solution for a window lock consists of three parts, a lock housing embedded in a hole milled in the side of the frame, a button attached to the side of the frame and a lock tongue insert embedded in the frame. To install the lock, three different machinations have to be done with three different blade heads. In order to fasten the lock, in addition to hitting the lock housing and the counter iron 20, the button has to be fastened to the lock housing with screws through holes drilled in the front surface of the frame. The fixed button is usually only secured in place at the construction site. Frequent pressure windows are also often used, in which case only the front plate of the button is attached with screws.

In addition to numerous work steps, this previously known solution for window locking is functionally poor. The operation of the window lock is based on a pre-pivotable tongue which is guided by a tapered slot in the counter-iron, which presses through the tongue closer to the frame of the window 30 and causes compression of the seal between the frame and the frame. However, the compression on the seal caused by the gap of the counter-iron is relatively small and cannot be increased as the elasticity of the seal decreases or the framework is distorted. Particularly detrimental is the lack of adjustability if the window 35 is subsequently replaced with a seal of a different design with a lower sealing height when installed at the factory.

From the resident's point of view, this previously known window lock is cumbersome in operation, because a detachable button is required when used. The release button disappears easily and it is difficult to put it in place, for example, when washing a window. It is not known from the outside whether the tongue is in the locked position or whether it may have been forgotten in the open position, in which case in a window closed by several locks one must try all the locks in several positions before everyone happens to be openable. In a tight window, where the tongues of the locks may be rusted due to prolonged inactivity, the situation is particularly awkward.

10

On the other hand, in a known window lock when using a fixed button, the large protrusion of the fixed buttons from the window surface is cumbersome because the space they take up when transmitting windows is large. When unprotected, the buttons may also cause abrasions and paint breaks in the adjacent window 15 during transport. As a result, fixed buttons often have to be fixed on a construction site, which causes an extra work step, which is also expensive when performed on buildings.

20 In another previously known solution, a threaded wing screw projecting through a ring bolt attached to the side of the window frame as a window lock locks the frame to an internally threaded sleeve attached to the side of the frames. The retaining device is then easy to control and its tightening can be increased by turning the wing-25 screw deeper into the counter sleeve. As simple as this previously known solution is, it also has its drawbacks. Because the tightening force can be easily increased, there is a risk of the seal flattening to the bottom, causing the seal's elasticity to be lost over time. The wings of the wing screws from which the rotation takes place do not always fit in the 30 corner positions and when the other half of the wing has to be removed, it is cumbersome to rotate by hand. Adjacent frames cannot be fastened in parallel to the intermediate frames due to the narrowness of the back of the frame, whereby the special nature of the fastening points causes the mounting of different mounting holes in the frame and increases the possibility of inaccuracies. The lowering locking devices are also not beautiful in appearance.

The object of the invention is to provide a locking device for the inner frame of a window, in which there are no disadvantages and problems of the previously known locking devices.

5

The object of the invention is in particular to provide a locking device which, with its simple and strong structure, can be easily installed already at the factory and, in addition, is safe in operation to eliminate the disadvantages in the locking devices of the previously known solutions.

The window inner frame locking device according to the invention is mainly characterized in that when the handle is closed, the bunches pull the gap between the frame and the frame smaller and flatten the seal between them, which seals the gap between the frame and the frame, and that the joint outside the frame, providing a stable lock.

In addition, other advantageous features of the locking device according to the invention are set out in claims 2-6.

The window inner frame locking device according to the invention has a simple and strong structure, so that it can be easily installed at the factory. In addition, the locking device 25 according to the invention has a low structure, so that the space it takes up does not substantially increase the size of the transmission package of the windows. There is also little or no risk of scratching.

The locking device for the inner frame of the window according to the invention is easy to use and in addition it allows the sealing gap to be adjusted to suit.

In addition, when using the window inner frame locking device according to the invention, the manualness of the windows can be determined and selected without special measures.

The window inner frame locking device according to the invention will now be described in more detail with reference to the figures of the accompanying drawing, in which Figure 1 shows a side mounted part, Figure 2 shows the same device from a different perspective, Figure 3 shows a side mounted part and .

Figures 1 and 2 show a movable locking device part 2 attached to the frame 1, consisting of a threaded pin 4 attached to a hole 3 drilled in the frame 15, a handle 6 pivotally articulated to it by a shaft 5 The bundles 8 are attached to a mating piece 12 attached to the frame 9.

20

The part 19a of the handle 6 presses against the running surface 1a of the frame 1 and determines a stable locking position of the handle 6. The plane set parallel to the fastening position 18 of the gripper 8 passes inside the articulation point formed by the shaft 5, i.e. closer to the frame, i.e. over the "dead center" 25 of said articulation mechanism 5, providing a stable locking.

The height L of the handle 6 of the locking device from the front surface 1a of the frame 1 is only a certain part of the length C of the handle 6 in the direction of the plane of the window glass 1 '.

Figures 3 and 4 show a mating piece 12 attached to a bore 10 made in the edge of the frame 9 by means of a threaded pin 11, the protruding part of which has two claws 13 on opposite edges and between them a recess 14 deeper than the wire thickness of the gripper 8.

When the handle 6 attached to the frame 1 is turned about the shaft 5, the bundles 8 move closer to the mating piece 82 82969 attached to the edge of the frame 9. In this case, the hinges 8 pivotable on the holes 7 can be moved so that its loop 15 hits the mating 14 and below the recess 16. When the handle 6 is turned back on the frame, the frame 1 is tightened towards the frame 9 by the gripper 8 clinging to the mating piece 5. By measuring the length of the bundle 8 on the basis of the distance between the hole 3 in the frame 1 and the mating piece 12, the seal 17 flattens between the frame and the frame, causing the air gap between them to condense.

The tension caused by the seal 17 also holds the handle 6 against its frames 1. The shaft 5 connecting the handle 6 and the threaded pin 4 must then be located outside the gripper 8 in the fastening space 18. By adjusting the threaded pin 4, the correct position is obtained.

The sealing margin can be adjusted afterwards by turning the mating piece 12 up or down by means of a threaded pin 11, whereby the gap between the frame and the frame increases or decreases by the twisted distance.

By means of the opposite nail 13 at the point of the mating piece 12, an adjacent frame with a similar locking part 2 can also be locked in the same frame 20, whereby all the holes and fittings are in the same place. In this case, the hinges and locking devices of the frame are all obtained at the same height.

The threaded pins 4 and 11 of the locking device according to the invention can be dimensioned according to the pin hinges used in the window, whereby all machining can be performed with the same equipment and at the same locations. The handiness of the windows can then be freely determined and replaced according to local requirements by replacing the fittings 30 Without any other special measures.

The locking frame of the inner frame according to the invention has a low structure, whereby the space taken up by it does not substantially increase the size of the window transmission package, even if the fitting is already fastened at the factory. At the same time, 35 expensive construction lies on the construction site are saved. The window adjacent to the transmission packet then protects the wide back side 19 of the handle 6, which creates little or no risk of scratching in the tightly bound packet.

The locking device according to the invention is also simple in construction and graceful, the visible handle of which can be shaped and surface-treated in many different ways without changing its principal function. Similarly, a structure changeable e.g., so that the bunches 8 is made of sheet bunches 8 can be positioned in the handle 6 of the back side 19 of the inner side of the top of the invisible, the body may 10 be circular or oval etc. It is essential that the threaded bolt 4 of the casement 1 to the side attached to the pivoted sash 1, a bunch 8 of suitable length is movably attached to the pivoting handle 6 on the inner surface 1a, the other end of which grips the nail 13 of the mating piece 12 fixed to the frame 4 when the handle is opened., When the handle 6 is closed, the bundles 8 tighten the gap 1 while the seal 17 is compressed due to its resilience, sealing the gap between the frame 1 and the frame 9 and locking the window frame.

The invention has been described above with reference to only one preferred embodiment thereof. However, this is in no way intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claims.
