Description

BACKGROUND OF THE INVENTION

The invention concerns a piece of furniture provided with at least one drawer or the like, in which are provided closing means and locking means for the drawer itself against undesired opening, for example for use on vehicles and means of transport in general.

STATE OF THE ART

In the furnishing sector, the manufacture is known of pieces of furniture with drawers for use in the sphere of vehicles or the like, such as for example campers, caravans, boats and ships, where the furniture itself is subjected to movements and oscillations of such a size that undesired openings of the drawers are possible, with the risk of accidents to the occupants of the vehicles, or breakages of the drawers themselves with the objects contained in them falling.
In order to obviate this problem, various proposals have been made for the attachment of locking means suitably configured for releasably locking the drawers in the closing position.
In particular, in the field of pieces of furniture with drawers having pull-out guides provided with closing devices, currently called “self-closing” devices, configured, if fitted, for bringing the drawer towards a position of complete closure gently and without impacts by the use of deceleration devices, the application is known of separate locking devices having one or more hooking elements to anchor a part of the drawer, for example the front, to the body of the piece of furniture or to the fixed part of the pull-out guides; in this solution, the hooking elements are in general disengageable by means of the manual operation of a suitable control, for example a button or a knob, provided on the front of the drawer.
These separate locking devices, however, entail the need to carry out additional machining for fitting them to the piece of furniture and, because of the presence of the aforementioned disengagement controls, also imply aesthetic modifications to the front of the drawers.
There is also a different specific sphere of furniture having drawers without handles or similar gripping means, in which, for the purposes of opening the drawer, devices are provided, currently called of the “push” type, comprising at least one expeller and suitably configured releasable locking means; in this case, to open the drawer, the user must exert a brief thrust on the closed drawer to release the locking means and thus permit the expeller to generate a movement of the drawer in the opening direction by a first section sufficient for the user to grip the drawer and then open it completely.
To close the drawer again, on the other hand, the user must obligatorily push the drawer manually until it is brought into the complete closing position, in such a way as to reload the expeller and recouple the locking means.
The “push” type locking means provided on these pieces of furniture, however, because of their specific configuration, are not suitable for use on furniture with drawers having pull-out guides with the above-mentioned “self-closing” type devices, unless more complex solutions are provided in which the expeller is reloaded during part of the opening or closing movement of the drawer, allowing the self-closing device the possibility of subsequently coming into operation.
There is therefore a need to have available a piece of furniture with at least one drawer or the like for use on vehicles and means of transport, in which pull-out guides of “self-closing” type are provided for drawers, which will permit the normal use of automatic opening and closing when the means of transport is stationary, and in which locking means are provided capable of resolving the above-mentioned disadvantages when the means of transport is in movement.
Patent application US2006/82266 describes a self-closing device which comprises a stop for the sole purpose of preventing the guide recoiling when the drawer reaches the closing position.

OBJECT OF THE INVENTION

An object of the present invention is therefore to provide a piece of furniture with at least one drawer or the like for use on vehicles and means of transport, in which pull-out guides of “self-closing” type are provided for the drawers and wherein locking means are provided, suitable for this type of application and operable by choice or by necessity, which do not require additional machining to be carried out on the piece of furniture, having at the same time great constructional simplicity and reduced cost.

BRIEF DESCRIPTION OF THE INVENTION

The above object is achievable by means of a piece of furniture provided with at least one drawer or the like which can be pulled out with respect to the body of the piece of furniture, the piece of furniture comprising:

- a first and a second side walls,
- a first and a second pull-out guides for each drawer, each of said pull-out guides having a fixed guide part connected to a respective side wall of the piece of furniture and a movable guide part fixable to the drawer,
- a closing device for the drawer associated with each pull-out guide, each closing device comprising a base body connected to one of the fixed or movable parts of the guide, the base body having a sliding track for a slider operatively engageable with the other of said fixed or movable parts of the guide and stressed in the closing direction of the drawer by elastic means,
  characterised by comprising:

DETAILED DESCRIPTION OF THE INVENTION

In FIGS. 1 to 3, a piece of furniture is illustrated with drawer or the like according to a first embodiment of the present invention, comprehensively indicated with the reference number 10, which piece of furniture 10 features a body comprising a first and a second side walls, of which only one 11 is illustrated in the figure, the walls being arranged at the sides of the drawer 12 and provided respectively with a first and a second pull-out guides for the drawer 12 itself, of which only one 13 is visible in FIG. 3. For sake of clarity, the drawer 12 is illustrated in phantom with a dotted line, so as to make visible the guide 13 with the closing device and stopping means and locking means according to the invention, as explained below.
Each pull-out guide 13 features a fixed guide part 14 connected to the respective side wall 11 of the piece of furniture, a movable guide part 15 fixable to the drawer 12 and, if fitted, an intermediate part, not illustrated, in the case of guides allowing complete pulling-out, which extend according to a pull-out direction of the drawer. The piece of furniture 10 also comprises a closing device 16 for the drawer 12 attached to or associated with each pull-out guide 13; as better illustrated in FIGS. 4 and 5, each closing device 16 comprises in turn a base body 17 fixed or connected directly or indirectly to one of the fixed 14 or movable 15 parts of the guide 13, in the case illustrated to the fixed part 14, which base body 17 has a sliding track 18 for a slider 19 operatively engageable with the other of the fixed 14 or movable 15 parts of the guide 13, in the case illustrated with the movable part 15 by means of a pin 20 integral therewith.
The slider 19 is stressed in the closing direction of the drawer 12 by elastic means, in the form for example of a traction spring 21, as explained below.
The closing device 16 also features a fluid-type linear decelerator 22 fixed or connected directly or indirectly to one of the fixed 14 or movable 15 parts of the guide 13, which is operable by the slider 19 or by an opposing element integral with the other part 14, 15 of the guide 13, as explained below.
Preferentially, the linear decelerator 22, for example of air or oil type, comprises a cylindrical body 23 fixed to an end of the base body 17 of the closing device 16, the cylindrical body 23 forming a chamber for a piston, not illustrated, whose rod is stressed or for example connected in articulated manner to the slider 19 of the closing device 16 to allow the slider 19 itself an oscillating movement with respect to the piston rod.
In fact, for the purposes of the selective engagement and disengagement of the slider 19 with the pin 20 which is integral with the movable part 15 of the guide 13, the sliding track 18 for the slider 19 features a first rectilinear section 18′ which extends according to the longitudinal direction in which the drawer is pulled out, wherein the slider 19 is engaged with the pin 20 to bring the drawer 12 to closure, and a second transverse section 18″ which branches off from the first section 18′ at a front end thereof facing towards the front 12′ of the drawer 12, in which the slider 19 by means of an oscillation movement releases the pin 20 to permit the completion of the opening movement of the drawer by the user.
The spring 21 extends and is fixed in a preloaded traction condition between a part fixed to the piece of furniture, for example the rear end of the cylindrical body 23 of the decelerator, and the slider 19.
According to the present invention, the piece of furniture 10 comprises also stopping means 24′ conformed and arranged to stop the drawer 12 in a first closing position, illustrated in FIGS. 1, 4 and 4A, in which the drawer 12 is spaced apart at a preset distance from the body 11 of the piece of furniture, for example of 2-4 mm, said stopping means 24′ being elastically yielding or overcomable by pressure on the drawer 12 in the closing direction up to a second closing position, illustrated in FIGS. 2, 3, 5 and 5A, in which the drawer 12 is more adjacent to the body 11 of the piece of furniture.
Furthermore, the piece of furniture 10 according to the invention comprises locking means 24″ conformed and arranged for releasably locking the drawer 12 in the aforesaid second closing position, said locking means 24″ being releasable by means of traction on the drawer 12 in the opening direction thereof.
In the first preferential embodiment illustrated in FIGS. 3 to 5A, the stopping means 24′ and the locking means 24″ are conformed and arranged for stopping and respectively locking the slider 19, specifically a pin 19′ which projects from the slider 19 itself, and consequently the drawer 12 which is integral with the slider 19 in the two above-mentioned closing positions.
In this embodiment, the stopping means 24′ and the locking means 24″ are formed spaced apart in a longitudinal direction respectively on a front side and on a rear side of a first and a second protruding elements or teeth 24, which project, transversely opposed to each other, from the opposite longitudinal edges of the sliding track 18 for the slider 19 at the rear end of the sliding track 18, in a position spaced apart from the rear end itself.
Preferentially each protruding element 24 has a triangular section having a first inclined front surface 24′ and a second inclined rear surface 24″ converging towards each other, which form respectively the stopping means 24′ and the locking means 24″ for the pin 19 and therefore for the drawer 12 which is integral therewith.
The operation of the piece of furniture 10 according to the invention is as follows: starting from the opening position of the drawer 12, a user who wants to close the drawer 12 must impose on the latter a movement in the closing direction; in this way, when the drawer 12 approaches the first closing position, for example at a distance of about 5 cm from said position, the pin 20 which is integral with the movable guide 15 on each side of the drawer 12 engages with the respective slider 19 causing it to oscillate as necessary to disengage it from the second transverse section 18″ of the sliding track 18.
At this point, the slider 19 is free to move longitudinally and therefore, under the traction action of the spring, brings the drawer 12 to the closing position with a movement suitably decelerated by the fluid decelerator 22 until it stops in the first closing position when the pin 19′ integral with the slider 19 comes into contact with the stop surfaces 24′ of the protruding elements 24 which project along the sliding track 18 for the slider 19 itself.
In this position, the drawer 12 can be easily opened again by the user and thus has an operation completely analogous to drawers equipped with conventional decelerated closing devices known from the state of the art.
In the event that there is a need to prevent accidental opening of the drawer 12 due to external actions, such as for example the forces which are generated during the movement of a vehicle or a means of transport on which the piece of furniture is mounted, according to the present invention, the user must exert a thrust or pressure on the front 12′ of the drawer 12 in the closing direction in such a way as to cause an elastic yielding and therefore an overcoming of the projecting elements 24 forming the stop surfaces 24′ by the pin 19′ integral with the slider 19, until the drawer 12 is brought into the second closing position in which the drawer 12 is more adjacent to the body 11 of the piece of furniture.
In this position, in which the pin 19′ is held by the locking surfaces 24″ provided at the rear to the projecting elements 24, the drawer 12 remains locked until the user exerts a traction action on the drawer 12 in the opening direction of the latter to release the pin 19′ from the locking surfaces 24″ by means of elastic yielding of the projecting elements 24, in such a way as to bring the pin 19′ again forward of the projecting elements 24 themselves and thus permit normal opening operation of the drawer 12.
The elastic yielding of the projecting elements 24 is brought about principally by deformation or stretching of the longitudinal edges of the sliding track 18 by the slider 19; in order to facilitate such stretching, the sliding track 18 is prolonged rearwards of the projecting elements 24 for a certain section.
As an alternative to the triangular section, the projecting elements 24 can have any other shape, for example rounded, suitable for forming a front stop surface and a rear locking surface for the slider or a part thereof.
It cannot be excluded furthermore that the closing device 16 for the drawer 12 may have a different configuration or that it may be attached to the side wall 11 of the piece of furniture or to the drawer 12, together with or separately from the stopping means and the locking means according to the invention.
Furthermore, the stopping means and the locking means can alternatively be configured in the form of additional elements attachable to the piece of furniture, in particular between the side wall 11 of the piece of furniture and the drawer 12, providing for example a component integral with the drawer that is stoppable and lockable by stopping means and respectively by locking means integral with the side walls, without prejudice to the characteristics and modes of operation thereof. In FIGS. 6 to 8 a variant of the closing device of FIGS. 3 and 4 is illustrated, in which the same reference numbers have been used to indicate similar or equivalent parts; in this variant, the stopping means and locking means are no longer formed in a single piece with the base body 17 as in the device of FIGS. 3 and 4, but are formed on a separate body 25, for example in the form of a flat fork, attachable to a base body 17 of the device suitably configured for mounting the separate body 25 itself.
In particular, with respect to the base body 17 of a closing device of known type, at a rear end of the sliding track 18 suitable fixing means must be provided, for example of snap-type comprising engagement housings 26 and/or teeth 27, couplable with complementary fixing means and/or with a part of the separate body 25.
This variant presents advantages in production and cost terms, because a single base body 17 is stamped to which may or may not be attached the separate body 25 having the stopping and locking means, depending on the type of use and operation required of the piece of furniture.
In FIGS. 9 to 10A a further embodiment of the closing device for the drawer is illustrated, provided with stopping means and locking means according to the invention, in which the same reference numbers have been used to indicate similar or equivalent parts.
In this embodiment, the stopping means are made up of an elastically yielding tooth 28 which projects into the sliding track 18 for the slider 19, formed from a strip 29 located on one side in proximity to the rear end of the track 18 itself.
This tooth 28, similarly to the stopping of the previous embodiment, is conformed and arranged for stopping the pin 19′ which is integral with the slider 19 and therefore the drawer 12 at the first closing position.
The locking means however in this case are of magnetic type and comprise for example a permanent magnet 30 arranged at the rear end of the sliding track 18 to lock the pin 19′, suitably made of ferromagnetic material, of the slider 19 at the second closing position of the drawer 12 once the user, by exerting pressure on the front 12′ of the drawer, has caused the elastic tooth 28 to be overcome by the pin 19′ itself.
As regards the operation of the piece of furniture, please refer to what was said with reference to the first embodiment.
As is evident from the above, thanks to the suitable configuration and arrangement of the stopping means and locking means according to the present invention, suitable for being connected to pull-out guides of “self-closing” type for the drawers themselves, undesired openings of the drawers are avoided, for example in the case of use of the furniture on vehicles and means of transport, with a solution that is constructionally simple, inexpensive and easily-assembled, without requiring additional machining of the piece of furniture itself.
The piece of furniture with drawer according to the invention is however subject to modifications and variations falling within the scope of the inventive concept; further, the constructional details are replaceable by technically equivalent elements.
