Description

Sliding windows without counterweights The great advantages of sliding windows are generally well known. The value of the sliding window without counterweights is increased by savings in materials and wages. You can can therefore be manufactured much cheaper than corresponding casement windows. To the handy Moving and slightly shifting the window frame, it is advisable to take into account the size measurements the window frame, which is 65 cm wide and 85 cm high, does not go out. The window are advantageous for apartments, youth homes, schools, etc. and can also be used by young people are moved, moved and turned inside for cleaning. It is important, therefore, that it be obvious how the locking bolts hold when moving the window frame prevent penetration inwards, kept in an exemption will. To avoid accidents and material damage, it is necessary to that when knocking back the inwardly folded window frames for cleaning in their in the vertical position, the locking bolts automatically go into the locked position immediately.

With sliding windows that do not automatically lock is available that is operated by older or technically inexperienced people and where the window frames folded inwards for cleaning are in the vertical Are tilted back position, the window frames fold back inward before the locking bars were brought into the locking position and therefore cause large Damage to people and materials. Young people who are often reckless or are scattered, the windows also operate unobjectively; an automatic bolt safety device is therefore absolutely necessary.

The invention consists in that on both sides of the inner feed frame Latches are attached to prevent the accidental penetration of the foldable Window frame prevent, but canceled for the intended folding of the wings by throws be, with the throws after swiveling the wings inward through Guide pins are again put out of action, so that the return movement of the Window frame in the perpendicular position is possible, but the locks against the unwanted penetration of the window frame inwards immediately back into the safety position step.

The further embodiment of the invention is based on the drawings explained and how it works.

Fig. I is an inside view of a two-part sash window; the casement frames are in the closed position vertically in the same alignment; Fig. Fig. 2 shows a section along the line fl-B in Fig. I on a larger scale; the locking bolt are in a free position to fold the casement inwards; Fig. 3 shows a View of the latch, in the locked position, and Fig. Q. shows a section along the line G-D in Fig. I with the casement folded inwards for cleaning.

The locking bolt i is firmly connected to a protruding pivot arm 2. It can be moved easily in the housing 3 and is supported by the pin q. pivotable stored. If the swivel arm z is pressed down and the cover 5 into the groove 6 of the swivel arm: 2 inserted, the locking bolt i is in the free position (Fig. a). If the window frames are moved inward, the guide pins 7 press the Throws 5 out of the grooves 6 of the pivot arms 2. The locking bolts i fall due to its own gravity back into the locked position (Fig. 4). The throws 5, which are attached to stands 8 or the like so that they can move easily, fall down into the open spring clamps g. The brackets 8 are fixed to the inner cover plates tied together. The inwardly folded window frame is in its vertical position moved back, press the guide pins 7 on the bevels io of the locking bolt i. Once the pins 7 have passed the locking openings, the locking bolts i fall again back to their basic position, the locked position.

The inwardly folded window frame (Fig. 4) has a secure support on the side strips ii and is held by pins 12 attached to the outer lining frame, which engage in the lower window frame 13. The lower guide plates 14 are wider than the guide grooves and prevent the window frames from moving upward.

The upper and lower window frames can be held in any position for ventilation by inserting the guide plate; 4 in plates 15 which have incisions. The guide pins 7 move almost in the entire depth of the groove guides 16, but the guide plates are 1q. and the cuts in the plates 15 are only two thirds as deep. This enables the window frames to be shifted smoothly and without interference.

All fittings are machined into the wood and just have to be screwed on.

Claims (3)

PATENT CLAIMS: i. Sliding window frame, which after moving out of the Can be moved up or down in the closed position in the vertical direction and if necessary, can be folded inwards in the lower position, without counterweights, characterized in that on both sides of the inner lining frame (i7) locks are attached that prevent the unintentional penetration of the foldable window frame prevent, but canceled for the intended folding of the wings by throws (5) the throws (5) after the wings have been pivoted inwards be put out of action again by guide pins (7), so that the return movement of the window frame in the perpendicular position is possible, but the interlocks against the unwanted penetration of the window frame inwards immediately back into the safety position step. 2. Sliding window according to claim i, characterized in that the locks by locking bolt (i) that keep their permanent closed position by their own weight and only when necessary through the covers (5) in the release position to be brought. 3. Sliding window according to claim 2, characterized in that the locking bolt (i) .ein extension in the form of a swivel arm (2) which has a Has groove (6) for receiving the cap (5), and that the locking bolt (i) is provided with a bevel (i) in the lower part.
