Description

Tandem trolley for windows and doors Sliding

The present invention relates to a car Adjustable tandem for sliding window and door leaves, these may be of metal profiles, PVC, wood, mixed or others.

State of the art

Normally, the leaves of the windows or doors slides where the carriage mechanisms are housed and fixed remain associated with a frame whose lower component consists of a track longitudinal in which they support through said mechanisms Carriage the sliding leaves.

The car mechanisms are found permanently associated to the sheet through various systems of fixing, these fixing elements are supported by the same mechanisms and constitute an indispensable part of the system of mooring, these fixing systems can be made up of various forms, among others, those formed by threaded locking elements or by stops of form and pressure.

These car mechanisms are very diverse forms and characteristics, can be formed by a single set of rolling or by several, can be adjustable in height to allow precise positioning of the blade during assembly, can offer rocker type systems to fit any irregularity of the track, may even present systems of thermal bridge break through plastic covers or Other diverse features.

The tandem carriage mechanisms are the configured by at least two wheels with rocker effect that allow to adjust the rolling to the possible imperfections of the track and ensure an improved opening and closing maneuver in the sliding windows and doors.

In solution EP0563015 a car is presented tandem of the adjustable type formed by a first hollow element that supports two wheels, and attached, by means of a mooring screw, to a rocker configured, in its upper zone, by an inclined plane; a second hollow piece wraps up the previous ones being associated, to through a transverse axis, with the rocker; the movement horizontal relative between both pieces is partially released thanks to the torn holes the rocker contains and that receive the aforementioned axis. The second hollow piece It has a complementary inclined plane configured in the rocker and two extreme holes where to place the elements of fixing directly attached to the profile of the sliding leaf. A adjustment screw placed laterally on the second piece hollow directly affects the rocker by sliding the inclined planes configured in the previous pieces and thus obtaining the consequent regulation in height of the leaf Regarding the frame. The need to make the three pieces compatible base members of the regulation mechanism directly affects quite high minimum dimensions of the set, which attached to a mechanism of complex components and laborious assembly gives as a result a high cost than the solution proposed in this document improves considerably.

Patent ES 2 096 903 T3 refers to a car adjustable tandem sliding type where the outer body is tied to the profile of the leaf by means of a pressure screw directly threaded at one of its ends. This body has, transversely to it, of a complementary inclined skate of the formed in the inner piece on which it slides so solidarity. A regulation screw placed outside the outer body and directly threaded into the inner piece allows the modification in the relative position between outer body and inner piece and the consequent height adjustment of the blade. The Tandem carriage configuration with slide control relative makes a series of inclined planes necessary complementary to both component parts of the mechanism. This skate is obtained by providing material throughout the transverse distance corresponding to the width of the outer body where it will support and will slide the corresponding skate of the inner piece. This support system involves lengthening the distance in an excessive way between the wheels so that they do not interfere with the skate previous intermediate, which means, again, a high cost that is improved in the proposed new solution.

Description of the invention

Considering the background above described the applicant thought about the realization of a mechanism Tandem type trolley that will optimize as much as possible the excessive size of current solutions providing equal or greater resistive and functional characteristics.

This new invention is configured so that the inner part can be removed without disassembling the blade of the sliding window or door.

In order to optimize the type carriage mechanism Tandem adjustable are configured each of the parts involved in the relative repositioning action so that the distance between wheels can be reduced and therefore the total size of the device.

The present invention seeks to eliminate the transversal continuity of the skates adopted in other solutions in order to enable the inclusion of lateral sections of slip closer to the wheels, and therefore decrease the space between them without any functional loss. The new sliding regulation concept by skates without transversal continuity eliminates a large part of material that in other current solutions caused distance restrictions between wheels and therefore in the size of the parts components.

The outer body includes in its walls lateral two protruding projections and straight geometry in their lower part and curve in the upper one that end up melting in its upper area through a transverse nerve with solution of continuity.

The inner part is configured to receive the Highlights described above in both guides equally elongated, with curved geometry in its lower and straight zone in the superior that converge in a space, free of material, destined to favor the rocker effect itself.

The special geometry of the highlights and lateral guides incorporated in the outer body and in the piece inside, respectively, play an important role when it comes to enable the rocker effect. This aspect, together with the design controlled interference between the component parts of the Tandem car, allow to maintain enough clearance to allow to the inner part work properly.

It is also thought to incorporate a new functionality that allows the use of the same adjustable tandem car as a simple mono-wheel car adjustable by the grafting of a new anti-rocker piece between the outer body and inner piece. Single wheel placement and the elimination of the clearance between outer body and piece inside through said anti-rocker piece It offers this new feature not known so far.

Said anti-rocker component accompanies the inner part when the first one is fixed, by two highlights, in the respective pockets practiced in the second. The own restriction in the movement of the inner piece with respect to the outer body makes the effectiveness of the solution.

Detailed statement of embodiments

With reference to the accompanying drawings, Figure 1 is a preferred embodiment where it can be observe the mounting of the tandem type trolley mechanism adjustable in the corresponding profiles 2 and 4 of the window or door slide. The profiles shown in the section correspond to the located in the lower part of the sliding window or door, the profile 4 where the outer body 5 of the Tandem carriage mechanism is a component part of the sliding blade whose weight will be transmitted through the inner part 6 and its respective raceways 7 to raceway 3 incorporated into lower profile 2 of frame 1, illustrated partially in figure 1.

The invention is shown in Figure 2 as a Tandem type trolley mechanism adjustable with the incorporation of two rolling assemblies 7 in the inner part 6, said part interior has several lateral grooves 19 that initially they develop in a truncated cone shape 25 to end in a circle segment 26 of sufficient diameter to accommodate the axis 20 of the rolling assembly 7 but with sufficient narrowness in the intersection zone 24 with the conical part as to prevent said rolling assembly 7 from coming out after assembly. The rolling assemblies 7 used in this type of solution have 20 double diameter shafts. The ends, with a diameter lower, serve as a coupling in the grooves 19 laterally configured in the inner part 6 while the central part, of a larger diameter, receives the corresponding wheel 21; own diametral difference causes the highlight enough for the axis 20 maintain its longitudinal position with respect to the piece interior 6.

There is the possibility of modifying the set of rolling 7, so that the axis 20 does not offer any type of highlight diametral; in this way, the lateral grooves 19 in the inner part 6 may be limited to mere circular holes that receive shaft 20 in assembly operations. These slits circular type will fit properly on the shaft to avoid possible longitudinal displacements thereof.

The outer body 5 is fixed inside the lower profile 4 of the sliding leaf by the respective Mooring means These mooring means preferably consist of in a pressure screw 9 housed in one of the ends of the outer body 5. The actuation of said pressure screw 9 causes its direct action on the profile of sheet 4. The opposing force that the outer body 5 suffers from the action of said screw 9 and the stop that said outer body 5 suffers from the configuration of the inside of the profile of sheet 4 in the which is fitted, makes it fixed in the desired position. The subsequent drive on said pressure screw 9, accessible from the bottom of the profile of sheet 4, enables the repositioning of the tandem car according to the desired requirements.

The outer body 5 inserted inside of the camera configured in the lower profile of sheet 4 you must fit so that the clearances in both directions, vertical and horizontal are controlled; in this way the outer body 5 can be extended with new external protrusions, both vertical and horizontally, to adapt to the respective chamber gaps desired

The adjustment screw 8 is placed externally to the outer body 5 and threaded therein to influence in the inner part 6, the maneuver of said screw 8 causes the relative displacement of the previous ones and the consequent gain or loss of distance between sliding sheet and frame. They are, mainly, the projections 22 and the lateral guides 17 incorporated in the outer body 5 and in the inner part 6, respectively, those that make such relative displacement possible and the usual height adjustment.

The projections 22 and lateral guides 17, of elongated and inclined geometry with respect to the direction of regulation, are configured so that the effect is favored seesaw, the clearances between guides 17 and projections 22 are sufficient to allow the pivoting effect while limiting the maneuver within safe margins. The highlights 22, symmetrical with respect to a central plane that crosses the body exterior 5 vertically, they have a straight geometry on their side lower and upper curve; the guides 17, also symmetrical with respect to a vertical plane that crosses the inner part 6 by its geometric center has one of its straight sides, the upper, while the lower one is curved. This relationship of supports between straight and curved surfaces makes it possible to generate the effect pivot required to match the inner part 6 with a rocker mechanism It is necessary to specify the non-limitation as for the shape of the guides 17 and highlights 22 that constitute the contact surfaces between inner part 6 and outer body 5, being able to vary dispositions, forms, inclinations, between others, in order to give the indicated pivoting solution and glide.

The projections 22 in the outer body 5 are preferably, so that the length thereof do not interfere with the rest of the carriage mechanism parts tandem, in this way there is a first segment 13 of the shoulder, of a shorter length, which should not interfere with the sets of rolling 7, while a second segment 14 free of interference with said rolling assemblies 7, can be extended and thus increase the support surface in the limit positions of regulation.

The inner part 6 fits into the body exterior 5 accessing from the bottom of it and doing slide the first one through its guides 17 on the highlights 22 of the second, the relative limit position held by both pieces guided is ensured by the maneuver of the pressure screw 9, this screw 9 will then serve as a fixing screw of the outer body, butt for securing the unit of the tandem carriage mechanism.

Assembly of the carriage mechanism of the tandem type adjustable and the accessibility of its regulation screws 8 and fixing 9 through the lower profile 4 of the blade, make it possible that the tasks of replacement or regulation in height and position are carry out without the need to disassemble the leaf profile sliding 4; This aspect provides great efficiency in case of maintenance or repair.

The inner part 6 has several reinforcements lateral 11, preferably in areas that support a greater working tension to expand the work sections and support surfaces. Several reinforcements 11 can be observed in the coupling area of the rolling assemblies 7 and in the limit zone of the sliding guides 17 that provide greater capacity Resistive to the whole. Continuing with the overspeakers of reinforcement several punctual projections 12 can be incorporated in the ends of the inner part 6 that ensure the correct parallelism and maintenance of clearances over the entire length of the inner part 6.

All of the above, described in the case of a Adjustable tandem carriage type assembly, may vary depending on our needs to get a functional assembly of the type mono-wheel carriage adjustable (see figure 4), for this is placed a new anti-rocker piece 10 directly associated with the inner part 6; the placement of this anti-rocker piece 10 eliminates the necessary clearance between inner part 6 and outer body 5 while preventing pivoting effect, this done together with the elimination of one of the rolling assemblies 7, preferably, the one placed next to the side of the adjusting screw 8 make it possible to use the mechanism of the Adjustable tandem carriage type with basic carriage functionality mono-wheel adjustable.

The placement of the piece anti-rocker 10 in the inner part 6 is carried out by inserting several protrusions 23 developed in the first in the corresponding cavities 15 of the second, the piece anti-rocker 10 is placed before mounting the inner part 6 in the outer body 5 following the same procedure mentioned above, the restriction of the movement due to the continuous guidance of the pieces and the securing retention between the two by means of the screw pressure 9 enable the safe assembly of the part anti-rocker 10.

An adjustable tandem carriage mechanism made of This form presents the main advantages of obtaining the more compact dimensions of the market keeping in full, and even expanding, the functionalities of this type of mechanisms The possibility of use as a car mechanism Adjustable mono-wheel is an important function added valid for all those solutions that do not require the Accuracy of a tandem carriage mechanism.

The ease of assembly, disassembly and regulation, whether of heights or position, is extremely accessible and simple without the need to disassemble the sheet.

The realization of the tandem carriage mechanism Adjustable described does not imply any limitation; in the case of heavy applications, for example, new reinforcements may apply or nerves, in addition to various geometries or different sets of rolling
