Description

Retractable rolling device for sliding doors.

Object of the invention

The present invention relates to a retractable rolling device for sliding doors, more specifically to a device that allows the wheel to be arranged in a inoperative position in order to prevent its deterioration by impacts during transport of the sliding door with the device rolling already mounted.

Background of the invention

In the market there are various types of devices and mechanisms to allow the rolling of doors sliding on guides or rails.

An antecedent of such devices is It is described in utility model U200100471 of the same holder, referring to an "improved support for doors Slides ", intended primarily for cabinet doors. This support defines a device comprising a piece of support attached to the internal area of the door by means fixing, preferably screws, presenting associated on its front surface a hollow housing body of a Rolling wheel by an outer rail. This hollow body is arranged with the possibility of sliding through guides verticals of the support piece, which allows its relative displacement Both elements are associated by vertical sliding pivots and coaxial springs supported on an upper projection of the support piece.

More specifically the top piece presents sliding holes of said pivots, so that when the hollow body is moved towards the upper area, the pivots move together with that and the springs are compress, tending to displace the hollow body assembly and the roll to the popup position. This upper projection has of a screw that delimits the depth of advance of the body hollow and that allows to define the maximum depth of advance of the hollow body in the position of maximum compression of the docks

The main problem of these devices or brackets is that once factory mounted on the door, the springs make the body hollow, and therefore also the wheel, protrudes from the bottom edge of the door, said blister wheel exposed to knocks and undue stress during the storage and transport of the door, which can cause damage to the contour or tread of the wheel and its rear malfunction.

Description of the invention

The retractable rolling device for Sliding doors, object of this invention, presents some technical particularities intended to allow the provision of the wheel in an elevated or retracted position during storage and transport of the door, in order to protect the wheel of possible impacts and reduce the risk of deterioration of said wheel.

The object retractable rolling device of the invention is of the type mentioned above, that is, comprising a support piece attached to the internal area of the door by means of fixing means, presenting associated in its front surface a hollow housing body of a wheel of rolling on an outer rail; meeting this hollow body arranged with possibility of sliding with respect to guides verticals of the support piece; the piece being associated of support and the hollow body by means of vertical pivots sliders and coaxial springs, which are supported by the lower base of the upper projection of the support piece, being in this upper projection a screw delimiter of depth of advance of the hollow body in an adjustable way.

According to the invention the device in issue comprises a hollow body retention piece in a retracted and inoperative position of the wheel; presenting said piece retention means for fixing to the upper projection of the support piece and a flexible tongue with a harpoon at its end lower, the hollow body comprising in its upper part a hitch window of said harpoon for retention in a upper position, with the wheel retracted relative to the edge bottom of the support piece, and therefore of the bottom edge of the door, avoiding its knocking and deterioration during transport and Door storage equipped.

To return the hollow body, bearer of the wheel, to the operative position, it is enough to elastically deform the tab as necessary to release the window harpoon of said hollow body, since the springs cause the mentioned return of the hollow body, and therefore of the wheel, to the position outstanding operation.

In a preferred embodiment, the means of fixing the retention piece to the upper projection are configured by two lateral extensions defined in the upper end of the flexible tongue and by a window or groove defined in the upper projection, so that said projection upper is tightly housed in the defined groove by both lateral extensions, without the need for screws or Other fasteners.

The flexible tongue additionally has a  lateral extension for easy manual handling during the release of the hollow body bearing the wheel.

In an embodiment of the invention the tongue flexible is made up of a single piece body of material plastic, which allows quick handling and assembly and a Low manufacturing cost.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows an elevation view of the device installed in a door, with the hollow body retained in a superior position, corresponding to the retracted position of the wheel.

- Figure 2 shows an elevation view of the device of the previous figure with the hollow body released and the wheel in outstanding operating position.

- Figure 3 shows a perspective view of the device of the invention.

Preferred Embodiment of the Invention

As can be seen in the figures referenced, the device of the invention comprises a piece of support (1) attachable to one side of a door (2) of sliding, in this case of a closet door, intended for facilitate its rolling, being coupled on said piece of support (1) a hollow body (3) carrying a wheel (4) and a retention piece (5) of said hollow body (3) in a position inoperative, retracted with respect to said door edge (2) and in which wheel (4) is retracted or removed to the area superior and protected against possible impacts during storage and door transport (2).

The support piece (1) is formed from  of a flat iron with an upper projection (11) and a projection (12) bottom opposite coupling to the door (2), comprising also some holes (13) for fixing by screws. This support piece (1) has two guides on both sides (14) vertical parallels for sliding mounting of the hollow body (3).

From the underside of the angled projection (11) of the support piece (1) two axes (6) face down equidistant, which are likely to stay in the holes (15), practiced in the upper base of the hollow body (3).

The hollow body (3) comprises at its end upper two parallel pivots (6) that pass through holes (15) of guiding defined in projection (11) superior of the piece of support (1), and a window (31) for anchoring the retention piece (5).

Around the pivots (6) are coaxially mounted two springs (7) that tend to keep the hollow body (3) in an operative lower position.

The upper projection (11) of the support piece  (1) also has a threaded hole (16) in which partially found a screw (8), whose end interior can be more or less close to the top of the hollow body (3) to limit its displacement. In said outgoing (11) above is also a window or slot (17) in the which the retention piece (5) is fitted.

This retention piece (5), formed in plastic, has some fixing means with respect to the piece of brackets (1) and a flexible tongue (51) that presents in its free end a harpoon (53) intended to be introduced into the window (31) of the hollow body (3), retaining it in an upper position, in which the wheel (4) is removed or retracted, and protected against possible impacts.

The fixing means of the retaining part (5) in the support piece (1) they are formed by two extensions (52) laterals defined at its upper end, and by the window or groove (17) defined in the upper projection (11) of the workpiece support (1). In the mounting position the extensions (52) they hug a portion of the upper projection (11), adjacent to the window (17).

The tongue (51) presents in an intermediate zone  a lateral extension (54) that facilitates its handling and manual bending during harpoon release operation with respect to the window (31) of the hollow piece (3).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
