Door retention device.

The present invention relates to a door retention device, especially for doors freezers and / or refrigerators, with a stand, in which you can pivotally articulate a door around an axis of turn, as well as a retention plate for fixing the support to a support surface of the door retention device, being able to rigidly fix the retention plate to the surface of support of the door retention device covering a foot section of the stand, so that the foot section is enclosed between the support surface of the retention device of doors and the retention plate.

To guarantee an exact closing of the doors and to be able to orient them precisely with respect to the opening of the corresponding device body has already been proposed to configure the door retention device in an adjustable way, of so that the support can be fixed in different positions to the corresponding support surface of the retention device doors. If holes are provided in the retention plate oblong, the entire retention plate can move along with the bracket and screw it again in the desired position in each case. Alternatively, the support can move, after release the retaining plate fixing screws, with with respect to this and then firmly re-tighten the plate retention. In this respect, it is difficult however to adjust the door really exactly in the desired position in each case. On the one hand, the weight of the door after the release of the retention plate may cause unintended slippage of the support. On the other hand, when tightening the retention plate itself there is also an unwanted displacement of the support or of the retention plate, so that the position previously found It is not maintained.

The present invention is therefore based on the goal of creating an improved door retention device of the aforementioned type, which avoids the disadvantages of the state of the technique and perfect the latter advantageously. Preferably, the adjustment of a door should be simplified articulated in a door retention device in position desired.

According to the invention, this objective is achieved. by means of a door retention device according to the claim 1. Preferred configurations of the invention they are the subject of the subordinate claims.

According to the invention, the retention device of doors is therefore characterized because the support can adjust in position with respect to the fixed retention plate rigidly, even with the retention plate fixedly mounted, that is, without releasing the fixing screws that fix the plate retention. The retention plate comprises for this a guide of displacement for the support, along which you can move the support, with respect to the retention plate, in a direction of travel perpendicular to the axis of rotation of the door and parallel to the support surface of the device door retention, being provided for the regulation of support along the scroll guide, even with the rigidly mounted retention plate, regulating means that they can engage on the one hand on the retention plate and on the other side on the stand. If the door should be adjusted transversely to its axis of rotation in one direction or another, the means of regulation so it only needs to be operated to move the support along the travel guide provided on the retaining plate on one or other sense This considerably simplifies the orientation of the door, since for this the plate does not have to be released retention, which would make the system unstable.

In an improvement of the invention is a resting surface provided in the foot section of the support  with which the support rests on the support surface of the door retention device. The retention plate forms a bra, which holds the foot section of the stand with its resting surface on the support surface of the device door retention. Basically you could also think of supporting the stand with its foot section exclusively on the plate retention, for example placing the foot section on the plate retention and insert it into means of travel guide adequate. Advantageously, however, the support is supported by across the resting surface directly on the surface of support of the door retention device, so that it produces a favorable flow of forces in addition to being able to achieve Easier construction of the retention plate.

The retention plate delimits in this case, in the state mounted on the support surface of the device door retention, a hollow space on the support surface of the door retention device mentioned, whose height corresponds essentially to the thickness of the foot section of the support. A clamp is essentially provided without play of the foot section of the support on the support surface of the door retention device. The retention plate can present lateral edge ribs and / or projections in chimney shape, especially threaded stud housings, whose lower sides form resting surfaces, with which the retention plate can drag on the surface of support of the door retention device, so that the side bottom of the retention plate is mounted at a height level defined with respect to the support surface of the device door retention.

To avoid scratching the surface of the body of the refrigerator and / or to facilitate movement to the adjust the support with the retention plate fixedly mounted, the resting surface of the foot section of the support may be provided with at least one sliding plate, preferably of a Hard plastic with adequate surface. Alternatively, the support surface may be configured in the area of the resting surface directly mentioned properly, for example polished or otherwise machined, to avoid scratching of the support surface of the door retention device in the body of the apparatus and / or to carry the coefficient of friction static or sliding at the desired interval.

The scroll guide can comprise basically guide surfaces configured differently. On the one hand, the scroll guide can present basically a slot open preferably to the side on the motherboard, through which the support penetrates through the base plate. Preferably, at the end of the passage in the form groove is provided at the open end a narrowing that prevents the support from sliding out of the motherboard in the direction of travel of the movement guide. Advantageously, the retention plate covers the foot section of the joint support in such a way that the support in the state mounted on the retention plate cannot be released from it. From This mode prevents unintended release of the media with The mounted door.

In an improvement of the invention, the guide of displacement can present guide flanks configured in the retention plate, which descend, tilted in the opposite way, in each case transversely to the direction of travel towards the stand's foot section and cooperate with guide flanks which also descend transversely to the direction of displacement in the mentioned foot section of the support, of so that the foot section is centered on one side and, on the other hand, it holds. The guide flanks extend in this case naturally parallel to the direction of travel, in perpendicular to the axis of rotation of the door.

Alternatively, or additionally, the nerves of the aforementioned side edge of the plate retention, whose lower sides form resting surfaces of the retention plate, can form guide surfaces of displacement. The foot section of the support has on its edges lateral corresponding sliding guide surfaces, whose separation from one another essentially corresponds to the distance of the opposite lateral edge nerves of the retention plate or is slightly smaller, so that the housing plate can be inserted with a slight play between the edge nerves side of the retention plate.

Alternatively, or additionally, in the foot section of the support can be provided notches of step as oblong holes, through which the plate of retention can be fixed by suitable fixing means, especially screws, to the support surface of the device door retention. The internal length of the notch as of oblong hole is dimensioned in this case, advantageously, such that its ends on the front side form surfaces stop that limit the travel of the support. The fixing means for the retention plate can form corresponding stop surfaces, against which the front sides of the notches as oblong holes when the end of the travel path is reached wanted.

The means of regulation for displacement of the support with respect to the retention plate may be basically configured differently even with the board tightly held retention. The use of levers is conceivable regulators, cams or the like. However, preferably, as regulation means a screw is provided which, on the one hand, gear in the support and, on the other hand, in the retention plate. In an improvement of the invention, the retention plate has in this sense an axial housing for the screw, in which the screw is fastened axially, although rotatably, while preferably in the foot section of the support is provided a threaded part in which the screw is screwed. The mentioned threaded part may be especially a threaded bore practiced directly in the foot section. However it is it is possible to provide a separate threaded part, which is subject to the foot section. In a sense, as opposed to this provision it could also be conceived to provide the threaded hitch on the plate retention and axial housing in the foot section of the support. The arrangement described previously simplifies however the accessibility of the screw head to drive the screw.

In an improvement of the invention, the retention plate can have an open cage to the side Bottom for receiving screw screw head regulator, which also has opposite sides, on the one hand, a passage opening for the regulating screw and, on the other hand, a passage opening for a screwdriver or hexagon wrench inside, for actuating the regulating screw. To this with respect to the opening towards the inner side is sized such that the screw head can be inserted into the cage which forms the axial housing and is removed again from it.

In an advantageous improvement of the invention, the retention plate, the support and the means of regulation can be previously mounted on a mounting module, of so that the mentioned parts are not released unintentionally some of others. For this, a retention plate can be provided retention tip protruding in the direction of travel of the travel guide, on which the support can move with a retention notch, so that the support is subject transversely to the direction of travel for prevent slippage of the retention plate. Preferably, the regulating screw retains the support in the been previously mounted in a position where the notch of mentioned retention covers the retention tip, so that the retention plate and the support are assembled forming a preassembly unit It is understood that, in an inverted manner geometrically, the retention tip could be provided in its case also in the support and retention notch or a corresponding retention notch in the retention plate. An especially advantageous embodiment provides that the support can move with a retention notch over the cage that houses the head of the regulating screw on the retaining plate.

To eliminate completely, after having done precise adjustment of the support by means of the regulating screw with with respect to the retention plate, an unwanted remaining game, in a improvement of the invention can be provided, in the support and / or the retaining plate, a clamping screw that acts transversely to the travel guide for tightening the support on the retention plate. In addition, this way you can be avoided, in case of insufficient automatic retention of the system, an unwanted progressive support mismatch.

In an improvement of the invention, the support has a connection section for drag connection of shape of a cross connector, which can be fixed on the body of the apparatus. Preferably, the mentioned connection section will be extends at least partially above the retention plate. To achieve additional guidance and support reinforcement, the connection section can be dragged together with the cross connector. Especially, a housing slot can be equipped with flanks parallel to the direction of travel, in which the profile of the cross connector can be introduced from tight way. An especially stable support occurs when the housing slot is configured in the form of a maze, in which the cross connector is engaged. This realization It has the advantage that no visible interstitium occurs when the support moves. Still there is a guidance and a additional reinforcement of the support situation. Opposite geometrically it could be conceived to provide the labyrinth also in the cross connector and provide a connection rib on the support correspondingly formed protruding, which meshes in This maze The embodiment described above has no however advantages with respect to connector manufacturing transverse, which can be configured for example as a profile extruded

A bearing bolt that forms the axis of rotation of The door can be fixed directly on the support. Preferably, the support has a housing eyelet corresponding, in which the bearing bolt is inserted.

Radially separated from this bearing bolt a roller is provided in an improvement of the invention on the bracket to capture a door closing capture arm which rotates with the door, this roller being housed so rotating around a roller axis parallel to the axis of rotation of the door. This ensures a capture or a coating softer capture arm closing door. In this way excludes surface damage, as it appears in the case of supports without roller. The door closing capture arm mentioned can be manufactured in the form of a bushing from a flexible material, such as for example POM, so that it can warp by the roller when the door is closed. Due to the tendency of the material to recover its original position, it is generated a force that closes the door when it reaches the neutral. The piece in this case it is advantageously configured in such a way that, in the closed state, there is still a slight previous tension, with what which door is kept closed.

The following explains in more detail the invention with the aid of a preferred embodiment and corresponding drawings. In the drawings they show:

The door retention device 1 shown in the figures is configured as a device for double door retention and serves for rotating housing of two doors arranged one above the other of a freezer and Fridge. It includes support 2, which can be fixed using the retaining plate 3 to a support surface 4 of the device door retention provided for this, which in the realization shown is formed by the front wall 5 of the body 6 of the apparatus.

As shown in Figure 4, support 2, in general terms comprises a section 7 standing in the form of plate, from which a section 8 of supporting arm extends, in whose free end is provided a housing eyelet 9, in the that a bearing bolt 10 forming the pivot shaft can be mounted of the door (see figure 1). Also, at the free end of the support arm section 8 is rotatably housed a roller 11 separated from the housing eyelet 9 and the bolt 10 of bearing housed therein, and specifically around an axis of rotation parallel to the axis of rotation of the door formed by bolt 10 of bearing.

The bottom side of the standing section 7 of the support 2 forms an essentially flat resting surface 12, with which the support 2 is placed on the support surface 4 of the door retention device, so that it rests on the same. On the mentioned resting surface 12 it is arranged in this case a sliding plate 13 made of a plastic adequate hard, so that the support, without scratching the surface of the support surface 4 of the door retention device, you can scroll over it as explained more in detail.

The support 2 is retained on the surface 4 of door retention device support by plate 3 retention, which can be rigidly anchored on surface 4 of support of the door retention device by means of suitable fixing, especially by means of two screws 14 of anchorage. As shown in figures 3 and 4, plate 3 of retention comprises a longitudinal groove 15 with which it can move retention plate 3 over arm section 8 bearing support 2, so that the retention plate 3 covers the stand section 7 of the support and retains it on the surface 4 of Door retention device support.

As shown in Figures 5 and 6, plate 3 of retention comprises a circumferential edge rib 16, whose lower side forms a resting surface 17 with which the retaining plate 3 rests on the support surface 4 of the door retention device. Anchor bolts 14 tighten the retention plate 3 with the lower side of the rib 16 of edge on the support surface 4 of the retention device mentioned doors. In this way it appears under plate 3 of retain a hollow space, in which standing section 7 is housed. The height of the mentioned hollow space corresponds approximately to the thickness of standing section 7, so that it is retained essentially no play on device support surface 4 of retention of doors, with which the contour of the lower side of the retention plate 3 is adapted to the contour of the side upper section 7 standing. As Figure 5 shows, in the lower side of the retaining plate 3 are provided flanks 18 guide that descend from the edges of the longitudinal groove 15  outward, that is, transversely to the longitudinal direction of said longitudinal groove 15, which extend in parallel to the longitudinal groove 15. In a complementary way to this, the standing section 7 of the support 2 comprises flanks 19 of guide descending from its section 8 bearing arm towards outside, which extend parallel to the direction of expected displacement of the bracket 2. In the mounted state, the guide flanks 18 mesh on the underside of the plate 3 of retention with the guide flanks 19 on the upper side of the standing section 7 of bracket 2. They form, on the one hand, a centering and, On the other hand, they serve as a travel guide. The guide of displacement is further formed by the edges of the groove 15 longitudinal, whose separation corresponds approximately to the thickness of the profile of the rear section 8a of the supporting arm. Such as shown in figure 5, the width of the standing section 7 is adapted in addition to the separation of the lateral edge ribs 16 of the retention plate 3, so that in this case a travel guide

In figures 6 and 7 it can also be seen that in standing section 7 of bracket 2 two holes are configured 20 oblong, through those that extend, on the one hand, the anchor bolts 14 for anchoring the retention plate 3. On the other hand, on the bottom side of the retention plate 3 are formed projections 21 of chimney-shaped guide extending in the oblong holes 20 mentioned and form, together with the anchor bolts 14, adjustment stops. As the Figure 5, in the position displaced completely out of the support, the guide chimneys 21 run into one of the ends of the holes 20 oblong. In the fully displaced position into the holder 2, shown in figure 6, the anchor bolts 14 run into the opposite end of the 20 oblong holes.

For the regulation of the support with respect to the retaining plate 3 is provided a regulator screw 22, whose screw head 23 is rotatably housed, but axially attached, in a cage 24 open to the side lower. The cage 24 is formed by walls adapted to the side bottom of retaining plate 3. On the outer wall of the retaining plate 3 that borders cage 24 is configured a notch 25 of passage, through which you can access the head 23 of the regulating screw arranged in the cage 24 with a proper drive tool. In the embodiment shown, the regulating screw is configured as a hexagon screw inside, so that it can be operated through the notch 25 step with an internal hexagon wrench.

On the opposite side of the recess 25, the wall of the cage 24 is also provided with a notch 26 passage, through which regulator screw 22 extends with its threaded section. It is screwed into a threaded hole 27 that It is made in section 7 of stand 2. It is understood that regulator screw 22 extends parallel to slot 15 longitudinal and to the other guide surfaces that form the guide 28 offset.

As can be seen in Figures 5 and 6, by turning the regulator screw 22 it can be adjusted towards a side and other the support 2 with respect to the support plate 3 in the longitudinal slot 15. This corresponds to the mounted state of the door retention device 1 for horizontal regulation of support 2, that is, according to figure 2, from left to right and vice versa, to regulate the doors accordingly housed in support 2.

As Figure 4 shows, between plate 3 of retention and the support 2 is also provided a screw 29 of press that, in the tight state, eliminates the game on the one hand remaining between the support 2 and the retention plate 3 and, on the other side, prevents unwanted displacement. In the way of embodiment shown sits in a hole 30 threaded into the section 8 bearing arm and can be screwed against a tightening surface 31 that borders arm section 8 bearing on the upper side of the retention plate 3.

The aforementioned tightening surface 31 is located on the upper side of the cage 24 housing the head 23 of the regulator screw and is part of a retaining tip 32 that borders the end on the front side of slot 15 longitudinal, on which a retention notch 33 is displaced in the contour on the front side of bracket 2. This coating allows the retention plate 3 and the support 2 to be assembled in a pre-assembled module, which facilitates the assembly of the door retention device 1. If bracket 2 is inserted in the longitudinal groove 15 of the retaining plate 3 and is fixed with regulator screw 22 until retaining notch 33 is moves on retaining tip 32, support 2 cannot remove from retaining plate 3 without releasing screw 22 regulator.

As shown in Figures 4 and 5, the slot Longitudinal 15 is open to one side, however forming the ribs 16 of edges at this open end of the groove 15 longitudinal a narrowing 34 that prevents an exit by unwanted slipping of bracket 2 when screw 22 is released regulator. The narrowing 34 is narrower than section 8a rear of the supporting arm. A narrowing 8b at the end upper section 8 bearing arm allows to release the support 2 despite narrowing 34 of the plate 3 of retention.

During assembly you can proceed from the following way: first, the retention device 1 of pre-assembled doors, on which support 2 has been carried by the regulating screw 22 preferably at a position of central part, it is fixedly mounted by means of screws 14 of anchorage in the place provided for it in the body of the apparatus. Then, in the sections that protrude to opposite sides of the bearing bolt 10, doors 35 can be engaged. If it turns out that the position of the doors 35 must be adjusted first only the tightening screw 29 is released. So with the retention plate 3 rigidly mounted, by screw 22 regulator support 2 is regulated horizontally to the position desired, until doors 35 are aligned in position desired. Then the tightening screw 29 is tightened again to eliminate a possible remaining game. During displacement of the support 2 with the retention plate 3 fixedly mounted, the sliding plate 13 on the bottom side of the support handles  that the surface of the body of the apparatus, on which the section 8 of support arm of support 2, do not scratch.

As Figure 2 shows, on the side bottom of the hooked door 35 an arm 38 may be fixed Door latch capture, which rotates along with door 35 and gears and disengages in roller 11, when the door opens and closes. The roller 11 on the support 2 thus guarantees a softer coating of arm 38 capture closure door. In addition, surface damage is excluded, as in the case  of supports without roller. As can be seen in Figure 2, the door closure capture arm 38, which may be preferably manufactured from a flexible material such as POM, It is deformed by roller 11 when the door is closed. Due to the tendency of the material to recover its original position, it is generated a force that closes the door after reaching or exceeding the point dead.

To achieve additional guidance and reinforcement of the support, this also connects to a transverse connector 39 mounted on the body of the device. To do this, a front section of the bracket 2 is configured as connecting piece 40 in drag shape. As shown in figure 6, on the side front located under roller 11 of arm section 8 bearing a labyrinth 41 is provided. In slot 42 of accommodation that forms labyrinth 41 can be introduced so adjusted the profile of the transverse connector 39. This also has the advantage that, when moving the support 2 to regulate the door position, there is no gap between the cross connector 39 and bracket 2.
