Description

DESCRIPTION SLIDING DOOR OF LIFT SLIDE TYPE OR WINDOW CARRIER UNIT The present invention, with a carrier unit for sliding doors or windows, especially to the type of doors known as “lift-slide” in trade jargon. or relates to the part constituting a carrier unit for windows.

These doors and windows normally include: - a fixed frame; - horizontally between the open position and the closed position relative to the fixed frame at least one movable blade that is slidable; - the above-mentioned opening of the wing associated with the lower cross member of the wing and a closed position to allow it to be shifted between at least one drive unit guided by the horizontal baseline; - positioned on the wing, first attach the lower seals of the wing to the side of the line away from the sides of the wing so that the aforementioned clear and to allow the sash to slide between closed positions. and secondly, the door or window a device that allows the sash to be lowered to the closed position to close it. remote control; - in the closed position of the flap controlled by the above-mentioned lever vertical member of wing with fixed frame for locking/unlocking locking/unlocking tools moving between

In this specification, in the majority of configurations on the market, the sliding window a pair of carriers (main and secondary) is focused on the carrier unit. 37957.01 One of the prior art construction solutions for each carrier of the unit: - on top, at the ends, even a pair of wheels designed to withstand a dry-shaped frame, to which it is hinged, and - allows raising and lowering of the sash relative to the box-shaped frame the lower part of the sliding wing and the box-shaped frame in order to provide includes a connecting body placed between

More specifically, according to some examples of prior art structures (these (can be seen in Patent Documents No. 3), the connector body, on one side, It connects to the lower part of the wing and on the other side is a pin and slant slot. a link between (depending on the solutions adopted, applied and made on the frame and connection body or vice versa) It is connected to the dry shaped frame via

The connection body (and wing) with respect to the box-shaped frame of the carrier a drive whose movement changes the relative position between the pin and the inclined seat. by the aforementioned joystick through its is provided.

In light of this, increasing the efficiency of lift scrolling mechanisms (here the term “efficiency” means more lever to lift even heavy wings. means that a small force will be applied), the wing to be lifted Preset designed to reduce weight and facilitate opening movement. loaded springs are used. Current Applicant's prior art solution is shown in Patent Document No. EP 2 220 316 A1 and in claim 1 describes a carrier unit according to the introduction. Other prior art It is explained in the document. 37957.01 However, with the presence of the pin - seat - spring combination, this The prior art solutions of carriers have several disadvantages.

The first problem is due to the 'tilted slot' guide unit present in the carriers. is happening.

Control starting with lever operation and ending with second carrier of the mechanism due to mechanical connections in series. It should be noted that the openings determine the total.

More specifically, the drive unit attached to the carriage is slidable attached to the lever. must be connected with the control bar.

A carrier with a connection between the drive coupling and the rod The prior art solution is described in Patent Document No. GB 1,093,352.

This connection must be closed during assembly, where the arm is completely lowered on the carriers. between the wing position and the open position with the carriers fully raised It needs to be fairly precise to allow for precise timing.

If this connection is not made definitively, the carrier unit its effective stroke is reduced or even insufficient for correct operation.

Therefore, the total clearances are due to the loss of stroke of the main carrier and sometimes even more. large degree of secondary carrier and consequent use of the stroke cavity (for example, the pin in the slanted slot).

In view of this, the loss of stroke is therefore a loss at the wing lift height. becomes a decrease.

In other words, with this slot system, more or less of the wing 37957.01 The effective lift value at which it is high depends on the sum of the openings that occur. This, The system thus formed on the carriers is, so to speak, of the rigid type. Because of its nature, it is a system that cannot be adjusted.

The second problem is that as the lift of the wing increases, the bow tends to 'off' and because it gradually reduces its relative contribution to raising the sash is the decrease in the capacity that the broadcast helps.

Therefore, this diminishing effect of the spring is the effect the user performs on the arm. is reflected in the maneuver, and essentially this maneuver is the last to raise the wing. exert greater effort during the final degrees of rotation of the arm that intersects my step. requires it.

Another problem encountered is due to the weight of the lifted wing. is formed.

In the system with slot, pin and spring, the weight of the wing is always with the inclined slot and it is associated with the whole series of mechanisms by folding it until it reaches the lever.

This folding effect of weight on the heavy wings can in some cases only open when touched, precisely due to the weight effect of the wing lead to insufficient stability of the arm that releases itself from the position. can open.

The object of the present invention is to overcome the above-mentioned disadvantages of the prior art. lift-slide type sliding doors or windows that overcome the provision of a carrier unit for

More specifically, the object of the present invention is the movement of the door or window. through its precise and adaptive connection to the system for Lift slider that can fully utilize the carriers' effective stroke width 37957.01 of a carrier unit for sliding doors or windows of the type is to provide.

An additional object of the present invention is that the user does not need to exert excessive effort. with a high degree of stability of the movable wing in the open position and without which allows the door or window to be opened and closed together, for lift-slide type sliding doors or windows is the provision of the carrier unit.

A further object of the present invention is to maintain high lift strokes, while also As with small-size profiles, any object forming the movable blade sliding doors of the lift-slide type that can be adapted to the profile type or is the provision of a carrier unit for windows.

For these purposes, lift-slide type sliding doors or fully accessible by the carrier unit for windows.

More specifically, lift-slide type sliding doors or carrier unit for windows, when in use, the lower cross of the sash associated with the part of the wing and in both the open and closed directions. at least resting on a horizontal baseline to allow includes a prime mover.

The main carrier, inserted in between and during use, inside the wing an operating (control) lever attached to and between the slidable bar and the wing positioned on and acting on the main carrier a motion drive that includes means for raising or lowering has the link.

On the other hand, the rod is connected to an arm. 37957.01 Open position by raising the sash relative to the line and also lifting and lowering arm from the first configuration to the second configuration and vice versa by turning the sash into line lever, flap, for controlling the closed position by lowering is positioned above.

According to the present invention, the operating lever of the drive link is securely attached to the bar. It has adjustable connection tools to be connected in a different way.

Again, according to the present invention, adjustable attachment means are used to lift the main carrier. of the rod with the relative configuration adopted by the tools and by the arm. position of the lever relative to the operating rod, keeping its position unchanged. It is designed to adapt. Rod - allowing the attachment point of the drive coupling to be adjusted thanks to this system, provided by the mechanisms controlling the carriers movement, with the lever at zero degrees with the wing in the lowered position in perfect timing between the arm at 180° in the raised position is protected.

In view of this, screw tools (38) are used to adjust the length of the blade (3). used and fixed point of contrast during neck (H) adjustment It is in contact with the connection mechanism (12) that forms it.

As already mentioned, the first frame 8 is provided with an through hole 30a. includes the vertical end wall (30).

In contrast, block (31) is in both directions, block (31) and second (9) and third for adjusting the screw means (32) to turn the frame (36) In order to allow direct access to the working elements from outside, correspondingly configured with the through hole (30a) of the first frame (8). contains the through hole (3la) (since the working elements are of known type, therefore not shown).

The adjustment system made in this way, after assembly, faulty alignment between the vertical member of the moving wing and the In this way, the position of the wing (3) can be adapted / Allows alignment.

Placement of a suitable tool on the rear end of the secondary carrier and screw tools By operating (32) the adjustment process is very easy and fast.

Screw means (32) connecting rod (12b), which is essentially a fixed contact element opposite one of the loop points of the lever: hence this is relative 37957.01 to the second (9) and third frame using nested end cavities (41 and 42). (36) allows the acting block (31) to be translated. Movement / rotation of the third frame 36 between slots 35 and 37 first, thanks to the connection with the [loop] point (P1) of the wheels (10 and 11) vertical movement (high I) of the second frame (9) in contact with the frame (8) low).

The vertical movement of the second frame (9), the first frame (8) and thus in 0 area determines whether the wing (3) can be raised or lowered and thus determines the alignment of the wing relative to the frame.

Thus, thanks to the above-mentioned structure, the carrier according to the present invention unit is fully reaching the preset targets. tie rods with reduced center-to-center distance and rotation, and the unit with the movement system using pairs of wheels, the unit that receives the carrier unit the advantage of reducing the dimensions of the profile and thus the profile costs in smaller cavities with a competitive advantage in terms of Allows the "scrolling" function to be achieved.

Pairs of swivel wheels, in line or with a door or window on it absence of linearity on the line caused by ground irregularities allows the wing to move correctly along the line even in it provides.

The tie rod mounted on the carriers is the most kinematic of the tie rods. reduced in the position where it is in the most critical position, that is, at 45°. stroke and maximum preload of the rear spring As the tie rods move to the vertical position, the spring load increases. 37957.01 loses power, but the kinematic mechanism greatly increases its efficiency and thus, with the tie rods at approximately 90°, the effort exerted on the arm is not for raising the wing, just to overcome the friction required.

The overall structure of the carriers described above depends entirely on the weight and weight of the wing. Regardless of any openings in the kinematic mechanism, the blade is fixed and It provides repeated lifting height.

Essentially, the connecting rods forming the lifting movement are at approximately 90°. if so, it generates the same removal value.

The combination between the lift bars and the first frame also in position, it unloads the load of the wing to the connecting rods, wheels, however, this load is not transferred to the arm and essentially this load is no longer transferred to the weight and weight of the wing. will not be more susceptible to the risk of unwanted returns.
