WARDROBE STRUCTURE WITH HARDWARE SYSTEM FOR HINGED OR SLIDING DOORS "

DESCRIPTION

The present invention relates to a cabinet structure with hardware system for hinged or sliding doors.

It is known that the wardrobe is one of the most common storage units in the home and office and that two systems are mainly used to open-close the compartments: hinged doors (hinged wardrobe) and sliding doors (sliding wardrobe ).

Industrial cabinet manufacturers normally make two different structures for the two types of doors, to satisfy the different needs of the two systems.

In industrial cabinets, the base is normally the same for the two versions and the lower shelf is raised 60 mm from the ground so that it can accommodate the overall dimensions of the lower rail of the sliding doors.

The top of the wardrobe, on the other hand, is normally positioned differently for each of the two opening systems: flush with the sides, for a wardrobe with hinged doors, and lowered instead of 60 mm, for a wardrobe with sliding doors. due to the need to create a space where to place the upper sliding track.

This condition means that also the central shoulders (sides) and the backs of the wardrobes must be of different sizes for the two door opening systems.

It follows that, with the same external dimensions of the cabinet, industrial manufacturers are forced to produce 35% more components than strictly necessary.

Another drawback is constituted by the fact that the useful internal height of the wardrobe varies by 60 mm between the hinged version and the sliding one with a further difficulty for the use of standardized internal equipment.

Another problem that storage cabinets have is leveling (leveling) after they have been filled.

It is known that the structures of the wardrobes, mainly produced with wooden panels, do not have a torsional rigidity capable of counteracting the forces generated by the weight of the objects stored there.

Often even the floors on which they are laid have a certain degree of flexibility and tend to compress even unevenly under the weight of the loaded wardrobe.

This is happening today, with increasing frequency, due to the diffusion of pre-finished floors laid dry on the load-bearing floor.

The leveling systems normally used do not allow you to level the cabinet when it has been filled, because the stored objects prevent you from reaching the leveling points that are located inside the compartments.

The aim of the present invention is to provide a wardrobe structure equipped with a special hardware system that allows both hinged and sliding doors to be used.

Within this aim, an object of the invention is to provide a cabinet structure which can be leveled from the outside even after the cabinet has been filled.

This structure, due to its peculiar construction characteristics, is able to ensure the widest guarantees of reliability and safety in use.

This and other purposes, which will appear more clearly later on, are achieved by a wardrobe structure with hardware system for hinged or sliding doors, characterized by the fact that it comprises sides and backs of the same size surmounted by a hat, which has the same height of a base on which the sides and backrests are applied.

Further characteristics and advantages of the object of the present invention will become more evident through an examination of the description of a preferred but not exclusive embodiment of the invention, illustrated by way of non-limiting example in the attached drawings, in which:

Figure 22 illustrates the whole of the entire front part in a cut-away on the axis perpendicular to the side in correspondence with the gears;

Figure 23 shows the front part in a cut-away on the vertical axis perpendicular to the side.

With particular reference to the numerical symbols of the aforementioned figures, the cabinet structure, according to the invention, globally indicated with the reference HB / S, is characterized by the fact that the gap existing between the internal height of the hinged cabinet and of the cabinet sliding door is divided, thus obtaining a space of 45 mm both under the base and above the top, thus unifying the two structures, with the result that in the hinged wardrobe there is 30 mm less internal space, while in the sliding wardrobe you have 30 mm more.

The cabinet structure object of the present invention comprises a new sliding system, positioned below and above the cabinet structure, which has a height of 45 mm instead of the usual 60 mm.

To solve the problem of leveling the cabinet after it has been loaded with the weight of the stored goods, this structure includes a system of leveling feet, integrated with the joint between the base and the side and with a height adjustment system placed in front of the cabinet in the space under the base top.

Figure 1 shows the typical sections of the structures for wardrobes produced today by the industry: the reference HB is a wardrobe with hinged doors, while the reference HS refers to a wardrobe with sliding doors.

The above traditional structures are compared with the new wardrobe structure, indicated with the reference HB / S, capable of accommodating both hinged and sliding doors, rebalancing the internal height difference between the structures commonly used today.

The new compartment is 30 mm lower than the current ones with the hinged doors and 30 mm higher than the current ones with the sliding doors.

This makes it possible to produce a single cabinet structure for the two door opening systems with a considerable saving on the number of components to be managed.

The management of divisions and internal equipment is also simplified by having a single internal height.

Figure 2 shows the joint system between the side and the base integrated with the leveling feet with front accessibility.

The joining system comprises two assemblies: a front or front part and a rear part connected together by a rod of variable length which transmits the adjustment movement.

The height adjustment of the feet takes place in front of the cabinet so that it can be leveled when it is loaded and its structure has presumably undergone some adjustments compared to the initial leveling after assembly.

The adjustment is carried out by inserting a screwdriver or an Allen wrench in one of the two seats in the body of the front part and activating the internal kinematics that moves the foot up or down by turning it clockwise or counterclockwise.

The two seats correspond to the operation of the front foot and the rear foot.

Figure 3 illustrates the exploded view of the front part, in which the reference number 1 is the foot, or tip; 2 is an adjustment screw with a hexagonal through cavity; 3 is a bush fixed by pressure in the body 4 of the foot; 5 is a gear with a hexagonal shank; 6 is a screw for fixing the joint bushing; 7 is a front base; 8 It is an endless screw; 9 is a transmission shaft; 10 is a broadcast auction; 11 is a joint bushing; 12 It is a grain of the joint; 13 is a joint pin; 14 is a coupling pin bushing.

Figure 4 is an exploded view of the rear part, in which the reference number 1 is the foot, or tip; 2 is an adjustment screw with a hexagonal through cavity; 3 is a bush fixed by pressure in the body 4 of the foot; 5 is a gear with a hexagonal shank; 6 is a fixing screw of the joint bushing; 7 is a front base; 8 It is an endless screw; 9 is a transmission shaft; 10 is a broadcast auction; 1 1 is a coupling bushing; 12 It is a grain of the joint; 13 is a joint pin; 14 is a coupling pin bushing.

Figure 5 illustrates the whole of the entire front part in a cut-away on the vertical axis perpendicular to the side.

The set consists of an upper part, composed of elements 1 1, 12, 13, 14, which serves as a junction of the base plane to the side and a lower part (1, 2, 3, 4, 5, 8 ) for vertical leveling.

The two parts are joined together by means of the base 7 where the body of the foot 4 is pressed in at the bottom and the bushing of the joint 1 1 is anchored at the top by means of a screw 6.

The upper part (1 1, 12, 13, 14) is embedded in the base plane of the cabinet by means of two holes perpendicular to each other, the pin 13 is fixed to the side of the cabinet by means of the bush 14 inserted in a hole.

The dowel 12, screwed into the head of the bushing 11, engages in the cavity of the pin 13 and holds it firmly.

The front foot is adjusted by inserting and rotating an Allen key in the left seat of the base 7 up to the hexagonal seat on the head of the worm screw 8, causing the rotation of the same which, engaged on the gear 5, makes it rotate.

The hexagonal shank of the gear 5 is inserted into the cavity of the adjustment dowel 2 which is, in turn, engaged in the bush 3, fixed to the body of the foot 4.

The rotation causes the vertical displacement of the grain 2 and therefore the vertical adjustment of the presser foot.

Under the adjustment dowel 2 there is a foot, or tip 1, which rests on the ground and does not rotate.

The rear foot is adjusted by inserting and turning an Allen key in the right seat of the base up to the hexagonal seat on the head of the transmission shaft, causing the rotation of the same, which on the other side has inserted a hexagonal rod 10 which transmits rotation to the rear foot.

Inside, the operation of the rear foot is completely similar to that of the front foot.

Figure 6 illustrates the whole rear part in a cut-away on the vertical axis perpendicular to the side.

The joining parts between the base surface of the cabinet and the side are the same as those of the front.

The rear foot is adjusted as follows: the hexagonal rod 10, which comes from the front and which is inserted in the hexagonal head of the worm screw 8, by rotating causes the rotation of the same which, engaged on the gear 5 rotates.

The hexagonal shank of the gear 5 is inserted in the cavity of the adjustment dowel 2, which is in turn engaged in the bush 3, fixed to the body of the foot 4.

The rotation causes the vertical displacement of the grain 2 and therefore the vertical adjustment of the presser foot.

Under the adjustment dowel 2 there is the foot, or tip 1, which rests on the ground and does not rotate.

Figure 7 illustrates the hooking system to the front feet of the lower track of the sliding doors.

A clip 16 made of elastic material is snapped onto the body of the foot 4.

The clip 16 on the opposite side is provided with teeth with the arrow end which are used to snap the lower rail 17 which is suitably shaped.

Figure 8 is an isometric and sectional view of the lower rail for sliding doors, held in place by clip 16.

Figure 9 illustrates the hooking system of the upper track of the sliding doors to the special supports 18.

A clip 16 made of elastic material, the same one used for the lower track, is snapped onto the special support 18, mounted on the bushing of the joint 11.

The clip 16, on the opposite side, is provided with teeth with the arrow end which are used to snap the upper rail 19, which is suitably shaped.

The upper track 19 is provided in the lower part with a rubber gasket 20 which has the function of acoustically isolating the track from the cabinet structure.

This expedient allows to significantly reduce the amplification effect (sound box) that the cabinet structure exerts as a result of the small noises produced during the sliding of the trolleys.

Figure 10 is an axonometric and sectional view of the upper track 19, for the sliding doors, held in position by the clip 16, and of the anti-noise seal 20.

Figure 1 1 is an axonometric and sectional view of the lower track 17 and of the runner for the internal sliding door 21.

Figure 12 is an exploded view of the inner sliding sash 21.

Reference number 22 indicates a base; 23 is a torsion spring; 24 is a pivot of the oscillating shoe 25; 26 is a splined bevel wheel and 27 is the spindle.

The lower runner of the internal sliding door is composed of the base 22 screwed to the door on which an oscillating runner 25 is hinged by means of a pin 24, which carries at the end a grooved bevel wheel 26 which rotates around a pin 27 .

A torsion spring 23, inserted between the base 22 and the shoe 25, constantly pushes the latter upwards.

The shoe 21 is inserted in the lower rail 17.

Once the leaf has been positioned by hooking it to the upper track, by bringing the lower part closer to the track 17, the grooved bevel wheel 26 of the runner 21 interferes with a tooth facing downwards obtained on the track itself.

Thanks to the hinge point, the oscillating shoe 25 tilts downwards opposed by the torsion spring 23.

Figure 13 illustrates the continuation of the action: the tooth of the lower rail 17 fits into the groove of the bevel wheel 26 and the force of the torsion spring 23, in combination with the lateral surfaces of the groove, holds the system in the sliding position .

The angles of the side walls (25 ° inside and 15 ° outside) of the groove are sized to prevent accidental detachment of the wheel 26 from the track 17.

The force of the spring is suitably calibrated to maintain a constant thrust from the bottom to the top and to hold the splined bevel wheel 26 in position.

Figure 14 shows how the kinematic mechanism is sized to allow vertical adjustment of the leaf.

Figure 15 is an axonometric and sectional view of the lower track 17 and of the runner of the external sliding door 28.

Figure 16 illustrates the insertion and coupling of the sliding block 28 of the external door to the lower track 17, which takes place in the same way as the sliding block of the internal door 21, and the overall section of the lower track 17, with the internal doors and external in sliding position.

Figure 17 is an overall sectional view of the upper track 19 with the internal and external leaves in the sliding position.

The two leaves are supported by respective trolleys equipped with wheels that slide on special seats obtained on the tracks.

The vertical adjustment of the doors takes place by acting on the adjustment screws positioned at the ends of the trolleys.

Figure 18 is an exploded view of the upper carriage of the internal door, in which the reference number 29 represents the support bracket; 30 is an adjustment screw; 31 is an adjustment wedge; 32 is a central body; 33 is a pivot of a wheel 34.

The purpose is to make the central body 32 which contains the sliding wheel 34 move vertically inside the support bracket 29, in order to carry out the vertical adjustment of the door.

The central body 32 is guided in its vertical movement by two protruding guides which engage in two cavities obtained in the support bracket 29 and is held by two elastic protrusions which snap into and engage in two openings obtained in the bracket 29.

The central body 32 has at the ends of the upper face two inclined planes on which the adjustment wedges 31 engage, which slide horizontally between the central body 32 and the support bracket 29.

The movement is generated by the rotation of the adjustment screw 30 activated at the outer end with an Allen key, which engages in the adjustment wedge 31 thanks to a threaded part, and which is constrained in its terminal part to the central body 32. thanks to a seat obtained in its diameter which engages in a cavity obtained in the central body 32.

Figure 19 illustrates the movement that occurs inside the support bracket 29 during the vertical adjustment of the door.

Figure 20 shows a variant of the joining and leveling system previously illustrated in Figure 2, in which front accessibility for leveling takes place through two holes made in the base plane instead of under the base plane.

There are situations in which it is not possible to access from the front under the base plane to make the adjustment, this system solves the problem through a joint that vertically misaligns the plane of the transmission axis between the kinematic of the front foot and the access axis adjustment from outside the structure.

The joining and leveling part of the rear foot remains unchanged from what is already shown in Figure 2.

Figure 21 is an exploded perspective view of the front part, in which the reference number 1 is a foot, or tip, 2 is an adjustment screw with a hexagonal through cavity; 3 is a bush fixed by pressure in the body 35 of the foot; 5 is a gear with a hexagonal shank; 6 is a screw for fixing the joint bushing; 38 is a front base; 36 It is a worm with gear; 37 is a transmission shaft with gear; 10 is a broadcast auction; 39 It is a gear with a hexagonal cavity; 40 is a cover for the gear seat; 1 1 is a coupling bushing; 12 It is a grain of the joint; 13 is a joint pin; 14 is a coupling pin bushing.

Figure 22 illustrates the whole of the front part in a cut-away on the axis perpendicular to the side in correspondence with the gears.

The set consists of an upper part (1 1, 12, 13, 14) which serves as a junction of the base plane to the side and a lower part (01, 02, 03, 35, 05, 08) for leveling vertical.

The two parts are joined together by means of a base 38, where the body of the foot 35 is pressed in at the bottom and the joint bushing is anchored at the top by means of a screw 6.

The upper part (11, 12, 13, 14) is embedded in the base plane of the cabinet by means of two perpendicular holes, the pin 13 is fixed to the side of the cabinet by means of the bush 14: inserted in a hole.

The dowel 12, screwed into the head of the bushing 11, engages in the cavity of the pin 13 and holds it firmly.

The adjustment of the front foot takes place by inserting an Allen key in the left hole on the front face of the base plane, which activates a gear 39 through the rotation, which transmits the rotation to another gear with worm screw 36, which transmits rotation to a gear with hexagonal shank 5, which is inserted into the cavity of the adjustment dowel 2, which in turn rotates and which is engaged in the bush 3, fixed to the body of the foot 35 and therefore moves vertically along the axis of the presser foot.

Under the adjustment screw 2 there is a foot, or tip 1, which rests on the ground and does not rotate.

Figure 23 illustrates the front part in a cutaway on the vertical axis perpendicular to the side.

In practice it has been found that the invention achieves the intended aim and objects.
