Description

Bearing device for windows and doors Sliding

Technical Field of the Invention

The invention is included in the field of sliding doors and windows and specifically refers to a Roulette or bearing device configured to allow height adjustment of the door or window with respect to the surface on which the door or window rolls or, more specifically, the leaf of the door or window.

Background of the invention

Sliding doors and windows are usually comprise a frame and one or more horizontally movable sheets in the frame. The sheets may include crystals, etc., and have a considerable weight So that the leaves can move with some ease in the frame, can be provided with bearings in its lower part. These bearings may comprise some type of wheels or balls located at the bottom of the blade, for example, in a lower profile (for example, of aluminum) of the sheet. The frame comprises a surface on which they can roll these bearings, and often comprises a guide nerve on which the bearings support, so that the sheets can be moved with minimal effort. Bearings support the weight of the blade.

When sliding doors or windows are installed, it is important to get a correct alignment between the sheet and the frame and a correct orientation of the leaf in the vertical plane. This is not always easy, for example, due to carelessness that they can produce when the frame is installed, etc. Therefore, for facilitate the correct alignment between the sheet and the frame, you can it is convenient to incorporate the bearings in the sheet so that its position with respect to the blade, especially in the sense vertical, can be adjusted by the operator when performing the Leaf installation in the frame.

Description of the invention

The invention relates to a roulette, namely a bearing device configured to engage a sheet of a sliding window or door, to allow regulation in blade height relative to a surface on which it should move bliss. sheet (for example, on a support surface in the frame of the door or window) and / or a correct orientation of the sheet in the vertical plane.

According to the invention, the device It comprises the following elements:

- At least one bearing holder equipped with at least a bearing (if it is what is known as a "roulette simple ", has a bearing; in the case of a" roulette tandem "has two bearings, etc.).

- A support configured to be coupled to a lower part of the sheet, for example, in a lower profile of the sheet. The support comprises a housing in which the bearing carrier is coupled so that it can be moved between a first position corresponding to a minimum distance between the corresponding lower part of the sheet and the surface on which the sheet should move (that is, corresponding to a "minimum height" of the sheet -or part of the sheet- with with respect to the window or door frame), and a second position corresponding to a maximum distance between said lower part of the sheet and said surface on which the sheet should move (that is, corresponding to a maximum height of the sheet -o of said part of the sheet- with respect to the window frame or door).

- A skate or blocking element located in the scrollable support (for example, by sliding) between a retracted position where it allows the Bearing holder may be in its first position, and a position advanced in blocking the carrier in its second position, preventing him from returning to the first position.

In this way, the element of lock to determine the height of the blade with respect to the frame: moving the skate towards its advanced position, it is achieved that the Bearing holder is locked in an increasingly position. away from its first position, so that the bearing is locked in a position further and further away from the bottom of the sheet. Or, what is the same, moving the skate towards advanced position, the blade is raised with respect to the surface on which it rolls.

The device may include an item of regulation comprising a thread that can be screwed into a hole in the bracket and that sets a stop for the element of blocking. That is, the regulation element may be configured so that a part of the blocking element is in contact with the regulating element when the device is In use. In this way, by turning the regulating element, it it modifies its position whereby the "stop" position varies. In this way, by turning the regulation element, you can move the locking element to its advanced position. From In this way, the regulation element serves to determine in which position the bearing carrier is locked. Therefore turning The adjustment element can adjust the height of the blade with  Regarding the frame. The regulation element may consist of something as simple as a screw that can be turned with a normal screwdriver or with an Allen wrench. The element of regulation can be coupled to an O-ring in the bracket, so that the O-ring acts as a brake, preventing the regulating element rotate involuntarily.

The support can comprise guide surfaces  configured to guide the locking element in its displacement. Said guiding surfaces may comprise the minus an incline section set up so that when moving the blocking element towards its advanced position, said section inclined forces at least a part of the blocking element to deviate down, "pushing" the bearing carrier towards a lower position, that is, closer to its second position. In this way, by turning the adjustment element or screw, you can move the locking element "forward", with which, when doing this stop block element against the section tilted in question, it looks deviated down, which represents that the leaf is raised with respect to the. surface over The one that rolls.

The guiding surfaces may correspond to the edges of through holes in side walls of the support. In this way, it can be very easy to establish such surfaces in the production process of the support by injection into a mold. The block element may have a width similar to that of width of the support, so that it can be housed in the support with the lateral ends of the locking element supported at the edges of the through holes. With dimensions suitable of these holes and the locking element, the element block can be mounted on the bracket by simple operation of introducing the support element through one of said through holes.

The blocking element can be a skate elongated and / or can comprise two ends joined by two walls lateral, so that there is an empty space between these side and end walls. This saves material and Reduce the weight of the device.

The bearing holder may have a hole through and the device can include a screw that goes through this hole and it is screwed into a hole of the element of blocking. In this way, with the block element correctly mounted on the bracket, the screw attaches the bearing holder to the device through the locking element, so that there is no loose pieces and so that the pieces cannot be separated accidentally, without first unscrewing the screw. This assembly is easy and also allows you to replace the bearing carrier in the event that a bearing is damaged (even with the blade mounted, releasing the screw drops the carrier). He bearing carrier can be coupled to the locking element a through the screw with a certain play between both elements; this can be achieved by giving the screw body a length greater than the sum of the thickness of the material at the top of the bearing holder and hole depth in the element of blocking. If the through hole in the carrier is extended in the longitudinal direction of the device, the bearing carrier can swing around the screw, something that can be practical to allow adequate relative movements between elements.

The support, the carrier and the element of block can be made of metal, for example, from Zamac, an alloy of zinc that allows easy manufacturing of the elements, by injection in steel mold.

The device may also comprise at least a threaded element or "stud" to fix the support in the sheet.

The device may comprise a protection or outer coating of a non-metallic material, for example, of nylon, to provide an insulating effect. This type of protection can be useful when using the device in an installation or profile of the type "R.P.T." ("Breakage of Thermal Bridge "), in which no element is intended metal profile (usually aluminum) is in contact with a metal part of the bearing device. From this way, the thermal insulation characteristics of the door or window

Another aspect of the invention relates to a sheet for a sliding window or door, comprising at least a bearing device as described more above. The sheet may comprise a profile structure that hold a glass or similar, and with one or more devices of bearing coupled (for example, screwed) in the profile bottom of the blade, with the bearings facing down. Usually, its use at least two bearing devices, located one in each lower end of the sheet, with which you can adjust the height of each lower end of the sheet with respect to the surface on which the sheet should roll. In this way, you can achieve a perfect orientation of the sheet in the vertical plane, with its perfectly horizontal upper and lower edges, regardless of the eventual inclination of the surface on which the sheet should roll. On the sheet, the devices of bearing are preferably placed with the elements of regulation out, so that they are easily accessible to the  Operator during the installation of the blade.

Another aspect of the invention relates to a sliding window or door, comprising a frame and at least one sheet, the sheet comprising at least one bearing device according to what has been described above.

Preferred Embodiment of the Invention

As can be seen in Figure 1, the device comprises a support 3, a bearing holder 1 and a blocking element 4.

The bearing carrier comprises, in this embodiment of the invention, a wheel-shaped bearing 2, which rotates around the axis 22 that crosses the wheel. The wheel it has a contact surface with a cross section in "V" -like shape, so that a groove 21 is formed suitable for the wheel to engage on a guide rib 81 of a profile 8 of the frame of a sliding window or door (see Figure 9). The part of the bearing holder 1 furthest from the bearing 2 has a curved configuration 23 that establishes a fairly flat end 24, configured to rest on a pin 36 running through the support 3.

The blocking element 4 comprises two ends solids 41 and 42, joined by two side walls 43 and 44, with that the blocking element has a stable configuration and rigid, especially if it is made of metal. Block element 4 has an elongated configuration with an identical width or very similar to the width of the support 3.

The support 3 comprises a housing that establishes,  between its side walls 35, a housing 31 configured to housing the bearing holder 1, with its end 24 resting on the pin 36. In addition, the support 3 has, on its side walls 35, two through holes 34 with dimensions greater than of the side walls 43 and 44 of the locking element 4. Said through holes have edges that establish surfaces of guided 32, 33 for the blocking element 4; one of those surfaces of each through hole has an inclined section 33. The support also has a threaded element 37 (see also figures 4 and 5) by which the 3 sheet support, for example, in a lower profile of the sheet.

To assemble the device, you can first  place insert the locking element 4 through one of the through holes 34 of the support, until walls 43 and 44 of the blocking element 4 are flush with the side walls 35 of support 3. Then, the bearing holder 1 is inserted into the housing 31 from the bottom, supporting its end 24 on pin 36. Then, it is introduced, through a through hole 11 (see Figures 2 and 3) elongated on bearing carrier 1, a screw 12, which is screwed into the hole 45 of the blockage (see figures 1 and 2), so that the bearing carrier 1 is coupled to locking element 4 through of screw 12, but with a certain play between both elements (already that the length of the screw body 12 is greater than the sum of the material thickness of the upper part of bearing carrier 1 and of hole depth 45). In this way, the whole it is assembled and the elements cannot be separated without first unscrew screw 12. Since hole 11 is elongated and since the blocking element 4 and the bearing holder 1 are united with a certain game, the bearing 1 can "swing" around screw 12, which may vary its inclination with respect to the blocking element.

Block element 4 can move inside of the limits established by the edges of the holes passages 34 on the side walls of the pin, and the Bearing holder 1 can swing on pin 36.

Finally, in Figures 1 and 2 you can also  observe a regulating element 5 constituted by a screw Allen, screwed into a hole in a minor wall of the support, to through an O-ring (not illustrated) that acts as a brake so that to turn the screw the operator must exercise a minimum force high enough to prevent the screw turn without the operator acting on it; in this way, it is avoided that the screw rotates during the use of the sliding window a once mounted. It is important that once the position of the screw 5 by the operator, usually during the installation of the window or door, the screw hold this position, to prevent the sheet from being misaligned over the years of use of the door or window.

The screw 5 has a free end inside the support. When the device is in use, this free end (the screw tip 5) stops against the left end 41 (in this text, the left and right expressions refer to the orientation of the elements in the figures) of the element of lock 4. In this way, by turning screw 5 so that move to the right (further into the support), you can limit the movement of the blocking element 4 towards its position retracted (to the left) or, which is the same, turning the screw in this way you can "press" the element of lock 4 towards its advanced position, more to the right. When this is done, the inclined sections 33 of the guiding surfaces force the right end 42 of the locking element to move down. Since the block element stops against the bearing carrier 1, the lower the end 42 of the Locking element, below is wheel 2.

Figures 4 and 5 reflect the device with the Locking element 4 in both extreme positions:

In Figure 4, the block element is in its retracted position, and the bearing 1 is in its first position, with bearing 2 almost entirely inserted into the support 3. This position corresponds to a minimum height of support 3 (and the door leaf or window that incorporates it) with with respect to the surface on which it rolls. If there is weight on the device (which occurs when mounted), through the bearing 2 exerts a force on the bearing of way that rests on the blocking element, which is pressed against the free end of the regulating element 5.

Turning now the regulation element 5 in one certain direction, its free end penetrates more and more towards inside the support, and since the end 41 of the element of lock stops against the regulating element 5, the element lock is moved to its advanced position, in which this element can be seen in figure 5. In this figure 5, the blocking element 4 locks the bearing holder 1 in its second position, in which the bearing 2 is out of the support 3, in a lower position with respect to the support. This position corresponds to a higher position of the support (and the blade which incorporates it) with respect to the surface on which wheel.

In this way, as it has become clear, by turning the regulating element 5 in one direction or another, you can adjust the height of the support 3 (and the corresponding part of the sheet that incorporates it) with respect to the surface on the what wheel

Figure 6 illustrates a bearing 1A of according to an alternative embodiment of the invention, in which The bearing carrier is equipped with two 2A bearings. This realization corresponds to the so-called "tandem roulettes". He rest of the elements (support 3, locking element 4 and element 5) can have an identical configuration to the one has been described above, except when a bearing with two wheels, there is no pin 36. The function of support for the bearing 1 that makes this pin 36 in the embodiment described above, does it, in the mode of two 2A bearings, the second bearing. The bearings are left automatically leveled because the bearing 1A can  tilt around screw 12 through a hole elongated (identical to hole 11 in bearing 1).

Figure 7 schematically reflects a embodiment of the invention in which the support of an outer protection 6 of nylon, which serves to prevent the metal of the support and the locking element come into contact with the metal of the window or door profile. This configuration corresponds to the facilities known as R.P.T. ("Thermal Bridge Break"), designed to improve the thermal insulation characteristics of the windows or doors.

Figures 8 and 9 illustrate, schematically, a sliding window or door with leaves 7 housed in a frame 8. Framework 8 is made up of profiles, of which one lower, which is seen in section in figure 9, presents two Guide nerves 81 for each leaf. Sheet 7 comprises a series of profiles, including the lower profile 72, which can be seen in section in figure 9. This profile 72, which supports the weight of the glass 71, houses, in its lower part, the support 3 with its bearings (2, 2A); nerve 81 of frame 8 profile is located in a groove 21 formed by the "V" shape of the Bearing.

In this text, the word "understand" and its variants (such as "understanding", etc.) should not be interpreted excluding, that is, they do not exclude the possibility that described include other elements, steps etc.

On the other hand, the invention is not limited to the specific embodiments that have been described but encompasses also, for example, the variants that can be made by the average expert in the field (for example, in terms of choice of materials, dimensions, components, configuration, etc.), within what follows from the claims.
