Description

BACKGROUND OF THE INVENTION The invention relates to a locking system for an element to be opened. In particular, the invention relates to a security lock for locking an openable element and to a method for locking the element.

Floor-to-ceiling patio glazing, balcony glazing above the balcony railing or glazing forming at least part of the outer wall are some examples of structures or arrangements which may comprise one or more elements that can be opened. Such an arrangement then generally comprises a lower conductor located in connection with the lower part of the elements and an upper conductor located in connection with the upper part of the elements to support the upper part of the elements and to move the elements at the upper part of the elements. The arrangement generally also comprises a locking system mounted on the guides, with locks attached to the upper and lower edges of the element and a tension-transmitting member, such as a wire, strap or rod. In addition, the locking system comprises a rotatable knob for guiding the upper and lower edges to the locked and simultaneously closed and open positions by means of a traction tension transmitting member.

Lumon Oy's instructions for the use of balcony glazing describe balcony glazing, in which the rotatable handle opens the upper end of the locking part by means of a traction transmitting member. The publication explains how to unlock by turning the lower latch clockwise, after which the next glasses are moved to the edge, opened and locked to the wall. An optional child lock with a lower latch is lockable. EP 1437473 describes a balcony glazing with latches at the top and bottom and between them a safety lock to which two separate traction members are attached. FI N 5695 U1 has a door button with a safety lock to prevent children or the elderly from swinging. The button has a cover plate and a hand part arranged at the end S of the spindle passing through the lock body. In addition, the button has a mechanism to prevent the spindle from rotating.

E 30 The above-mentioned systems can be installed on balconies, terraces N or other premises located, for example, in apartment buildings, schools, service buildings, 3 nursing homes, nursing homes for the elderly or other public spaces. The locking system is easy to open, just by turning the knob, which is why the N system is not a very safe solution in families with children or in environments with a lot of elderly people or people with memory problems.

Brief description of the invention The object of the invention is to provide a new type of lock, locking system and method so that the above-mentioned problems can be solved.

The object of the invention is achieved by a security lock, a system and a method which are characterized by what is stated in the independent claims.

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

The invention is based on a new idea in which a method, a system and a safety lock have been developed, which comprises a locking part which acts as a child lock.

This locking member moves between the open and locked positions, preventing movement of the torque member when the locking member is in the locked position and allowing movement of the torque member when the locking member is in the open position.

The advantage of the method, system and safety lock according to the invention is that the locking part prevents the opening of an element, such as a balcony glazing, only by turning the torsion member.

In the solution according to the invention, the locking part in connection with the torsion member must first be pressed into the bottom, after which the torsion member can be turned.

Turning the torsion member releases the lock of the element, allowing the element to be opened.

Such an opening system is easy for an adult to open with one hand, but inconvenient for a child, a memory patient or an elderly person, which protects them from climbing out and escaping.

Another advantage of this solution is that the locking part is close to the torsion member, so that the locking part can be pressed down with one finger and the torsion member can be turned with the same hand.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 schematically shows an arrangement which can form, for example, a balcony glazing above a balcony railing, a floor-to-ceiling terrace glazing or at least a part of the outer wall glazing. The arrangement may comprise one or more elements 2 which can be opened and closed.

The arrangement according to Figure 1 comprises, in the horizontal direction, two elements 2 mounted side by side on the same line. The elements 2 may be glass elements. Each element 2 comprises a plate 3 and a lower strip 4 at the bottom of the plate 3 for placing the element 2 on the support of a sub-guide or rail 5 belonging to the arrangement. The plate 3 may be made of a transparent or opaque material such as glass, plastic or other suitable material. At the upper edge of each plate 3 there is further an upper strip 6 for supporting the upper part of the element 2 in the upper guide 7. The upper guide 7 located in connection with the upper part of the elements 2 allows the upper part of the elements 2 to be supported and the elements 2 to be moved.

The arrangement according to Figure 1 may further comprise a locking system 1 N for an openable and closable element 2, comprising a safety lock 8 on the edge of the element 2 and a locking member 9 on its opposite edge and a tensioning means 10 between the safety lock 2 and the locking member 9. The member 10 to be selected for fastening may be, for example, a wire, a belt, a string, a yarn, a nonwoven yarn E 30 or a rigging fiber. The security lock 8 can be located in the lower part of the element 2 and can be attached to the lower strip 4, for example to its bottom. The locking member 9 may be located at the top of the element 2 3 and may be attached to the top strip 6, for example to its top surface. The locking member 9 may be, for example, a pin lock comprising a pin and an automatic return member, such as a spring. The automatic return member tends to keep the pin up in the locking position in connection with the upper guide 7, locking the upper end of the element 2 in place. The locking member 9 can be opened by pulling on the tensile

from the man 10 attached to the locking member 9, preferably to the pin, the pin moving to the open position and the automatic return member collapsing, unlocking the upper end of the member 2.

In Fig. 1, the pin can be pushed down by the pulling movement.

When the traction movement is stopped from the traction tension transmitting member 10, the pin automatically returns to the locking position, for example upwards according to Figure 1, by means of an automatic resetting means.

Fig. 2 schematically shows an oblique front view of a safety lock 8 according to an embodiment, which can be used, for example, in the arrangement according to Fig. 1 for unlocking and closing the element 2.

The security lock 8 is installed in the system according to Fig. 1 so that it can come, for example, inside the lower strip 4 of the element 2 in the balcony glazing, in which case the element can be opened from inside the balcony.

The safety lock 8 comprises a body 17 and a bogie 13 operatively connected to the body 17 to lock the element 2 in place attached to the lower guide 5. In addition, the safety lock 8 comprises a torsion member 11 attached to the body 17 to unlock and close the bogie 13.

The torsion member 11 can be rotatably attached to the body 17.

According to one embodiment, the rotatable torque member 11 comprises a body 14 of the rotatable torque member 11 (Fig. 3) and a gripping surface 20 of the knob. The gripping surface 20 is a soft part which is pressed on the body 14 of the rotating member 11.

The gripping surface covers part of the locking part 12 as well as the automatic return member 15 of the locking part 12 and is comfortable to use.

The torsion member 11 is located in front of the safety lock 8, so that it can be easily turned, for example, from inside the balcony.

According to one embodiment, the torque member 11 can be rotated about its axis in both directions, i.e. in the case shown, the torque member 11 can be turned clockwise and counterclockwise according to the arrows 19.

The torque member 11 may be, for example, a knob or a handle.

The safety lock 8 also comprises a locking part 12 fixed to the body 14 of the torsion member 11, adapted to move the AN between the open and locked positions.

The locking part 11 can be slidably attached to the body 14 of the torsion member 11.

The locking part 12 may be a lock preventing the movement of the torsion member 11, such as rotation.

The rotatable body 14 of the torsion member 11 also comprises an automatic reset member 15 of the locking part 12. The safety lock 8 and the locking element 9 of the locking system 1E can be adapted to be opened by pressing the locking part 12 to the bottom and simultaneously turning the torsion element 11. 8 and locking- = element 9 in the automatically locked position.

If the locking part is located on the side of the torque N 35 member 11, the automatic return member 15 of the locking member 12 is then horizontal, whereby the torque member 11 and the automatic return member 15 of the locking member 12 move horizontally. The locking part 11 can be located with respect to the torsion member 11 in any direction, whereby the automatic return member 15 of the locking part 12 can be placed correspondingly parallel.

The locking part 12 can be adapted to prevent the movement of the torsion member 11 when the locking part 12 is in the locking position and to allow the movement of the torsion member 11 when the locking part 12 is in the open position. The locking system 1 can be adapted in the open position of the locking part 12 to allow the movement of the torsion member 11, whereby the tension transmitting member 10 rotates at least partially inside the safety lock 8, opening the safety lock 8 and the locking member 9 simultaneously to open and lock the element 2.

The locking part 12 can act as a child lock, increasing security on, for example, glazed balconies. The locking part 12 can be located in the immediate vicinity of the torsion member 11, for example at the base of the torsion member 11. This allows the locking part 12 to be pressed to the bottom with one finger and with the same hand to turn the torsion member 11, whereby the locking is opened. In this way, it is easy for an adult to unlock with one hand, but it is difficult for a child, the elderly or a person with a memory disorder to unlock. In Fig. 2, the locking part 12 is in the locked position, whereby it is visible outwards as a projection outside the torsion member 11. In the locked position, the locking part 12 prevents the torsion member 11 from being moved or rotated in any direction, whereby the safety lock 8 remains locked. As can be seen in Figure 2, in the locked position, the protrusion of the locking part 12 extends from the opening of the body 17 outside it. The body 17 comprises a slot into which the locking part 12 fits in the locking position, which prevents the rotational movement of the locking part 12, whereby the torsion member 11 remains in place and cannot be rotated. When the safety lock 8 is opened, the locking part 12 can be pushed into the open position, i.e. in the case according to Fig. 2 upwards, whereby the locking part 12 is pressed inside the body 17, allowing the torsion member 11 to be rotated and the safety lock 8 to be opened. When the torsion member 11 is released, it tends to return to the slot A by the automatic return member 9 of the locking member 9, the automatic return member 16 of the bogie 2 13 (Fig. 3a), the automatic return member 15 of the locking part 12 (Fig. 3c) and the slot design. E Fig. 3a is a schematic rear view of a cross-section of the N safety lock 8 according to Fig. 2 with the locking part 12 in the locked position. This 3 means that when using, for example, the balcony glazing according to Fig. 1, = the rear part of the security lock 8 is directed to the outside of the terrace. Fig. 3b schematically shows a cross-section of a side view of the safety lock 8 according to Fig. 2 of Fig. 35 and Fig. 3c schematically shows a cross-section of a front view of the safety lock 8 according to Fig. 2.

In Figure 3c, the front of the security lock 8 is visible from inside the terrace.

For the sake of clarity, the body 17 and the gripping surface 20 shown in Figure 2 have been removed from Figures 3a-3c. The safety lock 8 shown in Figures 3a-3c can be used in the arrangement according to Figure 1 comprising a locking system 1 for opening and closing element 2. The locking system 1 comprises a safety lock 8 and a locking member 9 on its opposite edge and a tensioning means 10 between the safety lock 8 and the locking member 9. The safety lock 8 comprises a torsion member 11 for unlocking the safety lock 8 and the locking member 9.

In addition, the safety lock 8 comprises a locking part 12 adapted to move between an open and a locked position, the locking part 12 being adapted to prevent the rotational movement of the torque member 11 when the locking part 12 is in the locked position, i.e. closed.

The locking system 1 is adapted in the open position of the locking part 12 to allow rotational movement of the torsion member 11, whereby the tensile tension transmitting member 10 moves or moves at least partially inside the safety lock 8, opening the safety lock 8 and locking member 9 to open and lock.

Figure 3b shows how the locking part 12 can be placed in connection with the torsion member 11.

Fig. 3c shows a front view of the safety lock 8, as in Fig. 2, and shows how the automatic return member 15 of the locking part 12, such as a spring, pushes the locking part 12 outwards from inside or inside the torsion member 11, the locking part 12 being in the normally locked position.

Thus, a part of the locking part 12 remains outside the torsion member 11 and the body 17 and is below the torsion member 11 as seen in the figure, preventing the torsion member 11 from being turned in any direction.

When the locking part 12 is in the locked position, the torsion member 11 cannot move or turn.

Pulling on the tension transmitting member 10 may cause the pin of the locking member 9 to be depressed and the locking o of the upper part of the element 2 to be released.

However, even if the locking member 9 opens, the element 2 remains locked thanks to the safety lock 8.

A The safety lock 8 further comprises a bogie 13 operatively connected to the body 17, around the upper part of which is an automatic return member 16, N 30 of the bogie 13, such as a spring, which keeps the bogie 13 in the automatically locked position and lower as seen in Fig. 3c.

One end of the tensile stress transmitting member 10 of the locking system 1 is attached to the locking member 9, preferably to the pin of the locking member 9, and the other end to the safety lock 8. In Figure 3a, the tensile stress transmitting member 10 passes from the locking member 9 to the safety lock 8 through the safety lock body 8 and N 35 through the bogie 13 and the bogie 13 through the automatic return member 15, finally attached to the lower part of the bogie 13.

The tensile stress transmitting member 10 is thus integral, extending from the pin of the locking member 9 through the safety lock 8 to the bar 13. As it passes through the safety lock 8, the tensile stress transmitting member 10 passes through the safety lock body 17 and the pins 21 and 22 of the torsion member body 14. The pivot pins 21 are located at a distance from the central axis of the body 14 of the torque member 11. Thus, when the torsion member 11 is pivoted about its central axis, the pivot pins 21 deflect the tensile stress-transmitting member sideways away from a straight line as illustrated, for example, in Figs. 3a and 4a. In this case, the tensile stress transmitting member 10 moves inside the body 17 and the distance between the ends of the tensile stress transmitting member decreases. This pulls the pin of the locking member 9 and the safety lock 8 to the open position of the bogie 13.

In the embodiment shown in the figures, the tensile stress transmitting member 10 is adapted to rotate the central pin 22 of the body 14 of the torsion device 11. The tensile stress transmitting member 10 could also be adapted to pass through the central pin 22, i.e.

The central pin 22 is useful for the structure and bearing of the safety lock, but the structure of the safety lock 8 could also be implemented without the central pin 22, whereby the tensile stress transmitting member 10 could also run in a straight line between the pivot pins 21.

When the tensile stress transmitting member 10 is integral through the safety lock 8 from the pin of the locking member 9 to the bar 13, it is sufficient, for example, to tighten the tensile stress transmitting member 10 from one end. For example, the tightening at the upper end also acts on the bogie 13. This uniform structure also facilitates the centering of the pin and the bogie 13 of the locking member and makes it possible to adjust their position and movement simply by changing the automatic return members associated with them.

Fig. 4a is a schematic rear view of the cross-section of the safety lock 8 according to Figs. 3a with the locking part 12 in the open position. Fig. 4b schematically shows a cross-section of a side view of the safety lock 8 according to Fig. 3b 2 and Fig. 4c schematically shows a front view of a cross-section of the safety lock 8 according to Fig. 3c N 30 with the locking part 12 in the open position. E In the same way as in Figures 3a-3c, the security lock 8 shown in Figures 4a-4c can be used in the arrangement according to Figure 1. The locking part 12 of the safety lock 8 is adapted to move or slide between the open and locked position and to allow = movement of the torsion member 11 when the locking part 12 is in the open position, whereby the tensioning member 10 at least partially rotates inside the safety lock 8, as shown in Fig. 4a. , unlocking the security lock 8 and the locking member 9. As shown in Figure 4c,

how the locking part 12 is pressed, for example with a finger, inside the torsion member 11, whereby it is no longer visible outside the torsion member 11. As seen in Fig. 3c, the locking part 12 can be pressed upwards into or at the root of the torsion member 11. The torsion member 11 can then be turned in the desired direction, i.e. either clockwise or counterclockwise as seen in Fig. 4c. The locking part 12 remains inside the torsion member 11 when the locking part 12 is pressed. According to one embodiment, the locking part 12 should be kept pressed inwards as long as the torsion member 11 is turned 15 °. When the tensile stress transmitting member 10 moves at least partially inside the body 14 of the torsion member 11, it is shortened at the same time by pulling the pin of the locking element 9 and the bolt 13 of the safety lock 8 to the open position. In this case, the pin of the locking element 9 is depressed in the embodiment of Fig. 1 and the bar 13 of the safety lock 8 rises and the locking at both ends of the element 2, for example at the top and bottom, opens, whereby the element 2 can be opened. Figures 4a-4c show how the automatic return member 16 of the bogie 13, such as a spring, is pressed into the pile. In one embodiment, the bogie 13 further comprises a pin portion 18 which prevents the bogie 13 from opening when the locking portion 12 is in the locked position. If the bar 13 tends to open, i.e. to rise upwards according to Fig. 3b, for example when pulling the tension transmitting member 10, the pin part 18 stops at the stop 23 of the body 14, preventing the safety lock 8 from opening. This ensures that the locking system 1 cannot be opened even if the tension-transmitting member 10 is pulled. As illustrated in Fig. 4a, when the torsion member 11 is turned, the stop 23 pivots out of the way of the pin part 18, allowing the movement of the bogie 13 to the open position. The widths of the stop 23 and the pin part 18 determine how much the torsion member must be turned to allow the axle 13 to move.

o The locking member 12 and the bogie 13 of the safety lock 8 and the pin O of the locking member 9 have an automatic resetting member (15, 16), such as a spring, which tends to restore the locking member 12 of the locking member 9 and the locking part 12 and the bogie 13. position. When the locking part 12 is released from the open position, its automatic release member 15 returns the locking part 12 to the locked position. When the torsion member 11E is completely released, the torsion member 11 returns or rotates back to the initial position N and the tensile stress transmitting member 10 is at least partially released from the safety lock 8, locking the safety lock 8 and the locking member 9. When the torsion member 11 returns to its original locked position. by rotating in the opposite direction to the initial rotation of the N 35 torque member 11, the tensile stress transmitting member 10 loosens back to its original dimension, returning the pin of the locking member 9 and the safety lock 8 to the locking position of the axle 13 by automatic return means.

Thus, in the embodiment according to Fig. 1, the pin of the locking member 9 rises again and the bar 13 of the safety lock 8 lowers to its original position.

The automatic resetting members 15, 16 in the locking member 12 and the bogie 13 of the safety lock 8 and in the pin of the locking element 9 also return to their normal position.

According to one embodiment, when the torsion member 11 is completely released, the torsion member 11 automatically rotates back to the initial position and the tensile stress transmitting member is at least partially released from the safety lock 8, locking the safety lock 8 and the locking member 9. In another embodiment, recovery is slightly aided by turning the torque member 11 in the opposite direction to when unlocking.

Whether the torsion member 11 needs to be assisted in the recovery depends on the clearances, the tension of the tensile stress transmitting member 10 and the tension of the assembly screws.

Once opened, the element 2 can, if desired, be closed and locked back securely in its original position.

In this case, the locking part 12 of the safety lock 8 can be pushed into the open position and the torsion member 11 can be turned to open the bolt 13 and the locking member pin of the safety lock 8 to the open position, whereby the element 2 can be returned to the lower and upper guides 5, 7. 11 rotates automatically or with assistance back to the initial position and the tensile stress transmitting member 10 is at least partially released from inside the safety lock 8, closing the lock of the safety lock 8 and the locking member 9.

The security lock 8 as described above can easily be installed on existing elements and glazing.

Fig. 5 illustrates a method for opening and closing the element 2 by means of the locking system 1 described above, which locking system 1 may comprise a safety lock 8 on the edge of the element 2 and a locking member 9 on its opposite edge AN and a tensioning means 10 between the safety lock 8 and the locking member 9. The safety lock 8 may comprise a torque member 11 for unlocking and closing the locking member 9 of the safety lock 8 and 2, which locking part 12 can move between the open and locked positions.

The locking part 12 can prevent the movement of the torsion member 11 E when the locking part 12 is in the locked position and allow the movement of the torsion member 11 N 54 when the locking part 12 is in the open position.

In the method, the locking system 31 can allow the movement of the torsion member 11 in the open position of the locking part 12, whereby the tensioning means 10 can rotate at least partially inside the safety lock 8 by locking the safety lock 8 and the locking member 9.

It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above but may vary within the scope of the claims. o
