Description

The invention relates to devices for horizontal blinds located between the bindings of a glazed casement element of a window or door or fastened to the surface of the inner cover of the casement element of a window or door facing the inside of the room, or mounted on a stationary window or door unit or in a window or doorway, with fixtures for fixing in a given position of the cord regulating the length of the opening of the blinds.

The names of the individual parts of the proposed device and the details of window blocks and window frames (terminology) were taken by us from the Victory catalog: "Blinds for life. Catalog, 2003" and according to the book: N.G. Novosad. How to build a house. Yekaterinburg, Publishing House "U-Factoria", 2000

A device is known for fixing a predetermined opening length of horizontal blinds by fixing a cord that controls the opening length of the inter-frame blinds of the Holis system (see Victory catalog: "Blinds for life". Catalog, 2003; company phone: 7481199), which we consider as a prototype . The cord retainer is a wheel fixed flat with its side to the surface of the inner binding of the glazed door or window element facing the inside of the room and having a groove around its entire circumference. At the same time, the U-shaped corner that carries the blinds (the top rail of the blinds) is attached between two bindings (external, facing the street, and internal, facing the room) of the sash element of the window or the glazed door. The cord regulating the length of the opening of the blinds through the hole in the inner binding is displayed in the room.

The free end of the cord is equipped with a tip made in the form of a hollow, truncated cone with a narrow closed and wide open ends. The free end of the cord through the hole in the narrow end of the cone is inserted into the cavity of the tip and secured there by tying on the free end of the cord a node whose outer diameter is larger than the diameter of the hole in the narrow end of the tip.

To fix the specified length of the opening of the blinds, the cord (holding the tip) is pulled from the U-shaped element carrying the blinds to the required length, inserted into the groove of the latch-wheel and screwed on its edge in 2-3 turns.

The disadvantage of this system is the low reliability of fixing the cord. The thin nylon cord that is commonly used to adjust the opening length of the blinds is resilient and has a slippery surface. The turns of the cord lying in the groove of the latch-wheel are weakly engaged relative to each other and slide on the surface of the wheel. The fixation is not tight enough. As a result, the cord often breaks from the lock-wheel and the blinds fall to the maximum length, which can lead to mechanical damage to the details of the blinds or the control cord. When the blinds are fixed in the upper (folded) position, the excess cord hangs from the latch-wheel on the window sill (window sill), clings to the edge of the window sill, and prevents the window from opening and closing. If the window consists of several (for example, 3-4) casement elements (sections), the free ends of the control cords intertwine, get dirty, make an unpleasant impression of chaos on the windowsill and prevent it from being used to place any objects, such as flower pots.

The same device of the cord lock regulating the length of the opening of the blinds, and, consequently, the same disadvantages of the fixation system are the external blinds of the Holis system, in which the U-shaped element carrying the blinds is installed, for example, on the surface of the upper horizontal bar of the inner binding of the glazed casement facing the inside of the room window or door element.

The objective of the invention is to increase the reliability of fixing horizontal blinds in a predetermined position (for example, in the upper, fully folded) by increasing the reliability of fixing the cord that regulates the degree of opening of the blinds, eliminating the hanging of the control cord beyond the bound or stationary block of a window or door, simplification and increase convenience of using the mechanism for controlling the length of the opening of the blinds and the mechanism for opening and closing a window or a glazed door.

The specified technical result is achieved due to the fact that the "Device for fixing a predetermined opening length of the horizontal blinds", in which the upper strip of the blinds, that is, the U-shaped corner carrying the blinds, is placed between the bindings or on the binding surface of the glazed window element facing the inside of the room or the door is either installed on the inside of the room, on the surface of the upper horizontal beam of a stationary window or door block, or is attached to the top rhnosti window or door opening, comprises exiting from the U-shaped member louvers regulating the length of the cord and cord lock position.

The cord position lock is made in the form of a flat wheel having a groove around the entire circumference of its ribs. The flat side of the latch-wheel is attached to the inside surface of the binding surface of the gate element or stationary unit.

The free end of the control cord is equipped with a tip, for example, made in the form of a hollow truncated cone with a narrow closed and wide open ends. The free end of the cord through the hole in the closed end of the cone is inserted into the cavity of the tip and secured there by tying on the free end of the cord a node whose outer diameter is larger than the diameter of the hole.

The inventive device differs from the prototype in that on the surface of the binding or stationary block facing the room, perpendicular to the surface and the edge of any bar or impost, a flat stop is attached having a cut that reaches the free edge of the latter and perpendicular to the surface of the bar.

The transverse dimensions of the stop surface exceed the transverse dimensions of the end face of the tip, through which a cord is inserted into the tip cavity. The length of the slot exceeds half the largest size of this end, and its width is less than any size of the end of the tip. At the same time, the width of the slot is sufficient for a free cord into it, regulating the length of the opening of the blinds.

The latch-wheel is attached to the surface of the binding or stationary block between the cord exit from the U-shaped element carrying the blinds and the flat stop so that the cord length is chosen such that the control cord thrown through the groove of the wheel edge and inserted into the slot of the flat stop provides a predetermined opening length of the blinds with a snug fit of the tip to the flat stop.

At the same time, the latch-wheel and flat stop interacting with the same control cord are installed either only on the binding or only on the stationary unit, and the cord tension and the tip fit snugly against the flat stop are carried out automatically - due to the weight of the louvers raised upwards, the louvers that tend to to fall down under the action of gravity (claim 1 of the claims).

The latch-wheel is attached to the surface of the binding or stationary block so that the control cord along its entire length, except for the point of bending through the wheel, is parallel to the edge of the bar along the surface of which the cord passes (Claim 2).

The flat stop can be installed on the same vertical binding bar or stationary block, at the level of which a cord regulating the length of the opening of the blinds is released from the U-shaped element of the blinds. Then the latch-wheel should be mounted on the same vertical bar, for example, in the region of an imaginary line connecting the lower corner of the glass with the lower binding angle or the inner corner of the stationary unit with the inner corner of the window / doorway (paragraph 3 of the claims).

Flat emphasis can be installed on the lower horizontal bar of the binding or stationary block (paragraph 4 of the claims).

The flat stop can be installed on a vertical binding bar or stationary block opposite to that vertical bar, at the level of which a cord regulating the length of the opening of the blinds is released from the U-shaped element, or on a similar impost. In this case, the cord should be thrown through two clamps-wheels installed in the region of imaginary lines connecting the lower corners of the glass, respectively, to the nearest lower binding angles or the inner corners of the stationary unit with the inner corners of the window / door opening closest to them.

In the case of installing a flat stop on the impost, the latch-wheel is located in the junction of the impost with the lower horizontal edge of the stationary unit (Clause 5 of the claims).

The latching wheels can be mounted with the possibility of rotation of each of them around the axis of symmetry of the wheel (paragraph 6 of the claims).

As a flat stop, a metal or plastic corner can be used, one shelf of which is attached to the surface of the binding bar or stationary block, and the second is perpendicular to the surface and the free edge of the bar on which this flat stop is installed and has a slot perpendicular to the surface of the bar (Clause 7 of the Formula inventions).

The angle between the flat stop and the surface of the bar may differ from 90 °. In this case, the flat stop can be tilted by 0.5-15 ° in the direction of the surface of the stop, with which the end face of the tip of the free end of the control cord is in contact in a position that secures the fixed length of the opening of the blinds.

On the same side of the flat stop, its free edge, through which the slot passes, may have a shoulder, and / or a pit or flat recess may be made in this surface, the diameter of which is equal to or greater than the maximum size of the tip surface interacting with it (paragraph 8 of the Formula inventions).

As a flat stop, you can use the “control handle lock”, which is an obligatory element of the Holis horizontal blinds device and is a plastic corner, one shelf of which is screwed onto the surface of the inner frame of the window or stationary block facing the room, and the second is perpendicular to the surface and rib of this bar and has a slot perpendicular to the surface of the binding or stationary block connecting the free edge of the shelf with a hole made in the center e of this shelf.

The invention is illustrated in Fig.1-6.

If the blinds are installed between the inner, facing the inside and the outer bindings of the glazed casement element of a window or door, then the cord 1, Fig. 1, which regulates the opening length of the blinds, leaves through hole 2 from the surface of the vertical bar 3 of the inner binding facing the inside of the room between the bindings.

If the blinds are installed on the surface of the upper horizontal bar of the inner binding of the glazed casement element of the window or the glazed door facing the inside of the room, the control cord 1 leaves the blinds at the level corresponding to the hole 2.

At the free end 4, Figure 2, the control cord 1 has a tip 5 (for which the control cord is pulled out of the frame), made, for example, as in the prototype, in the form of a hollow truncated cone with a narrow closed 6 and wide open 7 ends. The free end 4 of the cord 1 through the hole 8 in the closed end 6 of the tip 5 is inserted into the cavity 9 of the tip 5 and secured there by tying on the free end 4 of the cord 1 of the node 10, the outer diameter of which is larger than the diameter of the hole 8 in the closed end 6 of the tip 5, which is not allows node 10 to pass through hole 8 when cord 1 is pulled out of the blinds by the tip 5.

The control cord 1, drawn from the blinds, is fixed to the inner surface of the inner cover of the window or door element by the latch-wheel 12 and 18, Fig. 1 and the flat stop 13, 16, Figs. 1 and 20, Fig. 3. The latch-wheel 12 and 18, Fig. 1, is made in the form of a flat wheel 23, Fig. 4, fastening with its flat side to the surface of the bar of the window frame 24 facing inside and having a groove 25 around its circumference. The wheel is fixed with its flat side to facing the inside of the surface of the inner binder of the door element or stationary window or door block, for example, with a screw 22, Figure 1, or 26, Figure 4.

In this case, the supporting structure of the blinds - the U-shaped element 27, Figure 5, is attached between the glasses 28 to the upper horizontal branch 29 of the frame. The cord 30 regulating the length of the opening of the blinds through the hole in the inner surface (facing the room) of the frame is discharged into the room.

As a flat stop in the inventive device, a metal or plastic corner 31 can be used, FIG. 6, one shelf of which is attached to the surface of the frame 32, for example, with a screw, and the second shelf is perpendicular to the surface of the frame and has a slot 33 perpendicular to the surface of the frame.

The flat stop 13, 16, Fig. 1, and 20, Fig. 3, is a metal or plastic corner, one shelf of which is screwed to the binding surface of a window or door, and the second is perpendicular to the surface and the long axis of symmetry of the binding bar and has a perpendicular surface a binding slot, the length of which is equal to or greater than half the diameter of the tip 6 of the tip 5 in contact with the stop, Fig. 3, and the width is less than any section of the tip, but sufficient for the cord 1 to regulate the opening length of the sting and.

Consider fixing the control cord 1, Fig. 1, for the case when the blinds are installed between the inner, facing the inside of the room and the outer bindings or mounted on the facing surface of the upper horizontal bar of the inner binding of a glazed casement element of a window or a glazed door. At the same time, when the blinds are opened to their full length, the tip 5 of the free end 4 of the cord 1, Fig.2, hangs freely in position 11, Fig.1. To fix the blinds, for example, in the upper, fully folded position, the cord 1 must be completely pulled out of the blinds (or from the hole 2), thrown through the locking wheel 12 (inserted into the groove on the edge of the wheel) and inserted into the slot of the flat stop 13 so so that the tip 5, Figure 2, was at position 14, Figure 1, and its narrow end was facing the stop 13, located on the lower horizontal edge of the inner binding of the leaf element. In this case, the location of the latch-wheel 12 on the line connecting the lower corner of the glass with the nearest binding angle of the sash element of the window or door is chosen so that the control cord 1 along its entire length (except for the point of bending through the wheel) is parallel to the axis of symmetry of the binding bar, on the surface of which he passes. The length of the cord 1 is adjusted by moving along the free end 4 of the cord 1, Fig.2, node 10 so that when the position of the tip 5, Fig.2, at position 14, Fig.1, the narrow end 6 of the tip 5, Fig.2, tightly adjacent to the stop 13, Figure 1, and the blinds were maximally folded, i.e. were in the highest position.

If the blinds are mounted in / on a high and narrow binding of a glazed casement element of a window or a glazed door, the emphasis can be installed at position 16, Fig. 1, on the vertical edge 17 of the inner cover of the casement element (which is opposite the vertical edge 3). In this case, the control cord 1 must be completely pulled out of the blinds (or from the hole 2), thrown through two lock-wheels 12 and 18 (inserted into the groove on the wheel edge) and inserted into the slot of the flat stop 16 so that the tip 5, FIG. 2, turned out to be in position 19, FIG. 1, and its narrow end was turned to the stop 16.

The position of the locking wheels 12 and 18 on the line connecting the lower corner of the glass with the nearest binding angle of the door element is chosen so that the control cord 1 along its entire length (except for the points of bending through the wheels) is parallel to the axis of symmetry of the binding bar, on the surface of which he passes. The length of the cord 1 is adjusted by moving along the free end 4 of the cord, Fig.2, node 10 so that when the tip 5, Fig.2, in position 18, Fig.1, its narrow end was pressed tightly against the stop 16, and the blinds were minimized, i.e. were in the highest position.

The emphasis can be installed at position 20, Figure 3, on the same vertical binding bar 3, through which a cord 1 regulating the length of the opening of the blinds is released from the blinds into the hole 2 (or at the level of this hole), and the latch-wheel 12 can be mounted on the same vertical bar 3 binding in the area of the line connecting the lower corner of the glass with the lower corner of the binding. To fix the blinds, for example, in the upper, fully folded position, the cord 1 must be completely pulled out of the blinds, thrown through the locking wheel 12 (inserted into the groove on the edge of the wheel) and inserted into the slot of the flat stop 20 so that the tip 5, FIG. .2, was in position 21, Figure 3, and its narrow end was turned to the stop 20.

The length of the cord 1 is adjusted by moving along the free end 4 of the cord 1, Fig.2, node 10 so that when the position of the tip 5, Fig.2, at position 21, Fig.3, its narrow end was pressed tightly against the stop 20, and the blinds were minimized as much as possible, i.e. were in the highest position.

The tension of the cord from the outlet of the cord 1 from the hole 2 (or from the level of the hole 2) to the tips 5, Figure 2, located at positions 15, 19, Figure 1, and 21, Figure 3, and the tight fit of the narrow end of each tip to the surfaces of the flat stop 13, 16, Fig. 1, and 20, Fig. 3, respectively, are carried out automatically - due to the weight of the louvre plates raised up, which tend to fall down under the influence of gravity.

If it is necessary to additionally fix the opening of the blinds in any intermediate position, for example, in the opening position at half maximum length, an additional flat stop can be installed between the main stop (13, 16 or 20, Figs. 2 and 3) and the place 2 of the outlet of the control cord from jalousie.

In the inventive device, as a flat stop, a metal or plastic corner can be used, one shelf of which is fastened, for example, with a screw to the inner binding surface of the glazed door or window element, and the second shelf is perpendicular to the surface and the long axis of symmetry of the binding bar and has A slot is perpendicular to the surface of the frame.

In particular, the “control knob” of the known Hollis horizontal inter-frame horizontal blind system device, which is a plastic corner, one shelf of which is screwed to the surface of the window frame and the other has a perpendicular surface, can be used as an emphasis (without any changes) frame, a slot connecting the free edge of the shelf with a hole made in its center. In the Hollis system, the aforementioned slot and hole are used to insert into the hole a handle for controlling the angle of the louvre strips. The hole has a diameter smaller than the transverse dimensions of the narrow end of the tip 5, Figure 2, which does not interfere with the reliable operation of the inventive device.

The angle between the flat emphasis and the surface of the inner binding of the window or door element facing the inside of the room may be different from 90 °. The flat stop can be tilted by 0.5-10 ° towards the surface of the stop, in which the tip of the free end of the control cord abuts. On the same side of the flat stop, its free edge through which the slit passes can be provided with a shoulder, and / or a spherical or flat recess can be made in this surface, the diameter of which exceeds the diameter of the tip surface interacting with the stop. This will further improve the fixation of the tip to the stop.

The tension of the cord from the outlet of the cord 1 from the blinds through the hole 2 (or from the level of the hole 2) to the tip located at position 15, 19, or 21, Figures 1 and 3, and the end face of the tip fit snugly against the stop surface, respectively 13, 16 or 20 is carried out automatically - due to the weight of the raised plates of the blinds, which tend to fall down under the influence of gravity.

In the inventive device, the tip 5, Figure 2, can be replaced by any other tip of the free end of the regulating cord 1 - in the form of a ball or other hollow geometric shape, working on a similar principle. However, it is desirable that at the exit point of the control cord 1 from the tip 5, the latter has a flat platform perpendicular to the direction of the cord 1, which will provide a better fit of the latch to the surface of the flat stops 13, 16 and 20, Figures 1 and 3.

In the claimed device, the latching wheels 12 and 18, FIGS. 1 and 3, can be mounted with the possibility of rotation of each of them around the axis of symmetry of the wheel, for example, around a screw 22 or 23, securing the wheel to the frame. This will facilitate the tension of the control cord 1 and its introduction into the slot of the flat stop, as well as the smooth release of the cord from the fixing devices.

If horizontal blinds are installed on the surface of the upper horizontal bar of the stationary window or door block facing the inside of the room or are attached to the upper surface or the upper edge of the window or door opening, then the flat stop and the wheel locks are attached to the surface of the stationary window or door block or impost facing the interior of the room moreover, the emphasis is fixed perpendicular to the surface and the free edge of the nearest vertical or horizontal bar of the stationary unit or the post.

At the same time, the design, relative position, interaction and fixing procedure for regulating the opening of the cord blinds, flat stops and the tip of the free end of the cord fully comply with the above description and Figs. 1-3, except that the stops and locking wheels are not located on the bars of the inner binding a glazed casement element of a window or door, and immediately adjacent to their positions, on the fixed bars of a stationary window or door unit or its imposts.

So, the flat stop is mounted either on the same vertical block of the stationary block, at the level of which a cord regulating the length of the opening of the blinds is released from the blinds, or on the lower horizontal bar of the stationary block, or on the vertical bar of the stationary block, opposite to the level at which it is released from the blinds a cord regulating the length of the opening of the blinds, or on one of the imposts, and one or more latch-wheels installed in the area of the lines connecting the lower inner corners of a stationary window or door block nearest thereto bottom corners of the window or door opening and / or in the mullion joints with a horizontal bar of the stationary window or door unit.

For the latter variant of installing the blinds (on the surface of the upper stationary window or door block facing the inside of the room or on the edge of the window or door opening), the cord tension from the cord exit from the blinds to the tip that fits snugly against the stop surface is also carried out automatically - due to the weight of the lifted up louvre plates that tend to fall down due to gravity.
