- One main advantage of the lock according to the invention lies in its high properties of resistance to tampering given that it can only be opened using a magnet of appropriate power which can possibly be adjusted according to needs.
- the magnets necessary for opening the lock according to the invention must have a high power and therefore they are special products made by specialized firms and very difficult for the public to find.
- Another main advantage lies in the possibility of integrating the lock 1 in a device for the resting and the support of glass panels in a perpendicular position one in relation to the other.
- the further advantage is obtained of being able to remedy possible inaccuracies of gluing of the block or of the squared members to the respective panels and/or inaccuracies of assembly by means of a simple adjustment of the attachment of the squared members in relation to the block.
- Another advantage of the device according to the invention lies in its efficacy in supporting glass panels also of considerable thickness (for example 6-8 mm).
- Another advantage of the device according to the invention lies in its reduced overall dimensions and in the versatility of use with panels responding to even very different needs and functions. Moreover its final appearance (cube shape) without projecting parts allows the device according to the invention to achieve a quality aesthetic appearance.
- a last advantage of the device according to the invention lies in the ease of manufacture, which allows the possibility of production on a large scale and with low costs.

Abstract
Description
- In its more general aspect, the present invention relates to the technical sector of furniture with particular reference to the manufacture of furniture with frame made up of glass panels, such as showcases and the like.
- More particularly, but not exclusively, the present invention relates to a lock for showcases and similar furniture having a frame made up of glass panels connected one to the other and at least one movable glass panel (wing) which can be actuated to open and close from and against a side of said frame.
- The present invention likewise relates to a connection device for the resting and the support of glass panels in a substantially perpendicular position one in relation to the other, the device comprising a lock of the abovementioned type.
- It is well known that the manufacture of furniture with frame in glass, such as showcases and the like, entails the connection of glass panels, preformed to the required size, in a perpendicular position one in relation to the other, so as to obtain said frame.
- This is achieved by means of devices that join glass panels arranged perpendicularly one to the other in zones forming the corners of the frame. Said devices are designed and made so as to allow the resting or the contact between panels arranged perpendicularly and adequate support so as to maintain said panels in a perpendicular position one in relation to the other.
- It is likewise known that showcases made in this way are often fitted with a lock comprising two structurally separate parts which can be engaged one with the other, whereof one part is associated with the fixed frame of the showcase and the other part is associated with a movable panel (for example a wing) of the showcase. The movable panel can be actuated to open and close from and against a side of said frame with relative disengaging or engaging of the parts of the lock performed by an operator, for example by means of a key.
- Although various types of locks for showcases and the like are known which also use operating principles that differ widely one from the other, for example with coupling between mechanical or magnetic members, they have various disadvantages, including that of a certain complexity of manufacture and/or assembly, the latter requiring at times drilling of the glass, an operation not lacking in difficulties and which usually requires highly specialised staff, and/or that of possibly being tampered with relative ease.
- More particularly, as regards the possibility of tampering with the lock, it has to be said that this disadvantage is particularly felt in the area of mass retailing (supermarkets, hypermarkets, etc.) where there is usually massive use of showcases for displaying products on sale and there is the need to protect the products contained in the showcases from theft and/or from possible damage arising from vandalism.
- The technical problem at the basis of the present invention is that of making available a lock for furniture, particularly for showcases and the like, which is simple to manufacture and install and which has high and efficient properties of anti-tampering, in such a way as to overcome the previously mentioned disadvantages with reference to the background art mentioned above.

In the turret 6 aslot 10 is formed, open at the rear, that is to say on the side opposite the plate 7, and laterally on two sides orthogonal one in relation to the other, viaapertures 11 with a longitudinal extension. - The turret 6 is also provided internally with an aperture for placing the
slot 10 in communication with theseat 8 of the plate 7 and by which thepin 9, previously inserted from the rear of the turret 6 in the slot 5, is inserted in theappropriate housing seat 8. Advantageously, thepin 9 has ashank 13 passing through the aperture of the turret 6 and ahead portion 14 having a larger diameter compared to that of theshank 13 and of the aperture of the turret 6. Thishead portion 14 acts substantially as end of stroke for the insertion of thepin 9 in the aperture of the turret 6 and therefore in theappropriate housing seat 8, abutting against a wall 6a of the turret 6 inside theslot 10. Apeg 15 is also provided, interacting with thehead portion 14 in order to attach transversely thepin 9 in such a way that, once inserted in theappropriate seat 8, it can no longer move backwards and/or withdraw. - Advantageously, this
peg 15 is inserted in a hole 16 formed on a corner of the turret 6 inside the slot 5, said hole 16 forming a predetermined angle (preferably around 45°) in relation to the longitudinal and/or transversal axis of the turret 6. - In accordance with the present invention, the block of the
first portion 2 of thelock 1 is made in a metal material, more particularly stainless steel, or materials that are easily formed, such as zamac, aluminium and the like, preferably zamac. - The
second portion 3 of thelock 1 is an assembly of different components as shown in particular inFigs. 2 and3 . This assembly comprises a plate-shaped member 21 intended to be glued by methods per se conventional to the abovementionedmovable glass panel 4 of a showcase. The plate-shaped member 21 has a substantiallycylindrical bush 22 formed in one piece with the plate-shaped member 21 and provided with internal threading 23, thebush 22 projecting therefrom at the surface opposite that of attachment of the plate-shaped member 21 to theglass panel 4. - The plate-
shaped member 21 and thebush 22 are made in a metal material, more particularly stainless steel, or materials that are easily formed, such as zamac, aluminium and the like, preferably zamac. - The
assembly 3 comprises moreover a substantiallycylindrical body 24 shaped to make up a cover or a plug for thebush 22. Thebody 24 is in fact provided with anexternal threading 25 which can be engaged with the internal threading 23 of thebush 22 according to a threaded coupling so as to allow screwing and unscrewing of thebody 24 on thebush 22. - More particularly the
body 24 comprises ahead 26 provided with anaperture 27 for the passage of the pin 9 (specifically of the end portion of itsshank 13 housed in the seat 8) in the use of thelock 1 to close the showcase as will be explained in greater detail herein below, aportion 28 of greater diameter joined to thehead 26 and an end portion 29 provided externally with said threading 25. - Inside the plug body 24 a tapered cavity or
chamber 30 is defined which communicates at one end with theaperture 27 of thehead 26 and is extended laterally along substantially the entire longitudinal extension of thebody 24. Thischamber 30 is closed at the end opposite to that communicating with theaperture 27 of thehead 26 by abase wall 32 of thebush 22 when thebody 24 is engaged in thebush 22 by means of the threaded coupling illustrated above. - More particularly the chamber or
cavity 30 has a tapered portion 33a having a substantially truncated cone configuration with tapering turned towards theaperture 27 of the head 26 (or in other words in the direction of disengaging of thepin 9 from thebody 4 as will be explained in greater detail herein below) and a non-tapered portion 33b (that is to say having a substantially constant diameter) ending at thebase 32 of thebush 22 when theretaining body 24 is screwed in thebush 22. - The
body 24 of theassembly 3 is made in a non-magnetic material, preferably stainless steel. - The
assembly 3 of thelock 1 comprises moreover a movable (or floating)member 36 shaped substantially like a small barrel and inserted in thetapered chamber 30, themovable member 36 comprising acage 37 tapering towards saidaperture 27 of the head 26 (or in other words in the direction of disengaging of thepin 9 from the body 24) with tapering substantially equivalent to that of the tapered portion 33a of thechamber 30, and a substantiallycylindrical cavity 38 open towards thebase 32 of thebush 22. - The
movable member 36 is made in a magnetic and/or magnetisable material, in particular iron, so as to be able to be attracted by a magnet of adequate power placed in proximity of thelock 1 as will be explained in greater detail herein below in the description. - The
cage 37 is provided with opposite upper andlower apertures 39 for the insertion of thepin 9 inside thereof and possibly inside thecavity 38, the upper andlower apertures 39 being coaxial along the longitudinal axis X of theassembly 3 with theaperture 27 of thehead 26. - The
cage 37 is also provided with a plurality of lateral apertures 40 positioned radially and contains internally a plurality ofspheres 41, one for each radial aperture 40, thespheres 41 being able to project slightly from the respective radial apertures 40 and being movable only radially. - In the present non-limiting embodiment, the
cage 37 has three apertures 40 arranged radially at 120° one in relation to the other. Thespheres 41 are in a magnetic and/or magnetisable material, in particular iron. - The
assembly 3 of thelock 1 comprises moreover ahelical spring 42 inserted in thecavity 38 of themovable member 36 and supported by thebase 32 of thebush 22. Thisspring 42 exerts a force which tends to push themovable member 36 with therespective spheres 41 towards thebody 24, in particular against the wall or internalconical shoulder 43 of thebody 24 in the tapered portion 33a of thechamber 30. - As regards the functioning of the
lock 1, it has to be said that in the situation wherein themovable wall 4 is distanced from the fixed part of the showcase (showcase open), thefirst portion 2 and thesecond portion 3 are completely disengaged one in relation to the other. In this position, themovable member 36, with therespective spheres 41, is maintained in pressure contact, by means of thespring 42, against the internalconical wall 43 of the retainingbody 24. Due to the effect of this contact, thespheres 41 are pushed radially towards the interior of thecage 37, in a position wherein the free space between them in the radial direction is smaller than the diameter of thepin 9. - In order to bring the
lock 1 into the operative position of locking to which closure of the showcase corresponds, it is sufficient to bring thesecond portion 3 associated with themovable glass panel 4 towards thefirst portion 2 associated with the frame of the showcase in such a way as to insert thebody 24 and thebush 22 in theseat 8 of the plate 7 with simultaneous insertion of thepin 9 in theaperture 27 of thebody 24 and therefore in themovable member 36 by means of therespective apertures 39 until it is locked between thespheres 41. Given that the space between thespheres 41 is not sufficient for allowing the passage of thepin 9 between them, the insertion of thepin 9 has the effect of pushing themovable member 36 with therespective spheres 41 in the direction opposite that of the thrust exerted by the spring 42 (that is to say in the direction of insertion of the pin 9) until reaching a position wherein the conicity of theinternal shoulder 43 of thebody 24 allows a movement of thespheres 41 towards the exterior such as to create a sufficient space for passage of thepin 9 between thespheres 41. - At this point the thrust action of the
spring 42 on themovable member 36 prevails so that themovable member 36 is pushed in the direction of disengaging of thepin 9 until reaching a new position wherein thespheres 41 are in pressure contact with the internalconical wall 43 of thebody 24 and pushed towards the interior by this wall, thus compressing thepin 9 between them. - Thanks to the conicity of the
internal wall 43 of thebody 24, every attempt to remove thepin 9 from the retainingbody 24 only increases the pressure exerted by thespheres 41 on thepin 9, effectively making extraction thereof impossible. - Therefore the
lock 1 according to the invention constitutes an effective anti-tampering system for the showcase whereto it is attached. - It should be noted that, advantageously, in the position of locking of the
lock 1, thebody 24 and thebush 22 are inserted substantially wholly in theseat 8 of the plate 7. This is obtained by configuring theseat 8 on one side and thebody 24 and thebush 22 on the other with substantially complementary profiles so as to create, in the position of locking of thelock 1, substantially a shape coupling. - In this way a considerable reduction in overall dimensions is advantageously obtained, at the same time achieving a pleasing aesthetic effect.
- Moreover, advantageously, the
head 26 of thebody 24 is slightly conical to improve centring of thebody 24 with thebush 22 in theseat 8 of the plate 7. - Moreover the
head 26 is provided with anannular groove 44 wherein aring 45 in rubber or similar material is inserted, which has the function of absorbing shocks caused by the possible striking of the rear wall 8a of theseat 8 against thehead 26 of thebody 24 at the end of insertion of thebody 24 in theseat 8 to bring thelock 1 into the locking position. - In order to bring the
lock 1 into the operative position of unlocking or disengaging of thepin 9 from the body 24 (opening of the showcase), it is necessary to apply an external magnetic field of appropriate power in proximity of thelock 1, for example by means of a cylinder in magnetic material (a sort of magnetic key), which can be supplied to staff authorised to access the content of the showcase. - Given that the
movable member 36 is made in a magnetic and/or magnetisable material, the bringing of a magnet (not shown) of adequate power in the proximity of thelock 1 again entails the forward movement, through magnetic attraction, of themovable member 36 with therespective spheres 41 in the direction of insertion of thepin 9, in opposition to the thrust exerted by thespring 42, until reaching a position wherein the conicity of theinternal shoulder 43 of thebody 24 allows a movement of thespheres 41 outwards such that they no longer exert pressure on thepin 9. - At this point, again in the presence of said magnet, the
second portion 3 of thelock 1 associated with themovable glass panel 4 can be moved away from thefirst portion 2 associated with the fixed part of the showcase thereby allowing the disengaging of thepin 9 from thebody 24 and the opening of the showcase. - Advantageously, the moving away of the
second portion 3 from thefirst portion 2 of thelock 1 and hence of themovable wall 4 from the fixed part of the showcase is facilitated by the presence of ahandle 46 formed in one piece with the plate-shapedmember 21 and projecting from themovable glass wall 4. - In accordance with another aspect of the present invention, the
first portion 2 of thelock 1 can be associated with and/or form part of a device for supporting the glass panels of the frame of the showcase in a substantially perpendicular position one in relation to the other (or in other words at right angles one in relation to the other). - A device for the support of the glass panels of the frame of a showcase in a substantially perpendicular position one in relation to the other comprising a lock according to the invention is shown in
Figs. 4 and5 . - This device, denoted overall by 50, comprises the
lock 1 described above and a pair of squaredmembers 52, structurally independent one from the other and in relation to thefirst portion 2 of thelock 1, each having aplate 53 provided with anappendage 54 orthogonal thereto. Eachappendage 54 has anelongated slit 55 by which anattachment screw 56 passes with itsshank 57. Thisattachment screw 56 co-operates with a correspondingnut 58 sliding alonglongitudinal guides 59 formed in theslot 10 under alateral aperture 11 for attachment of the respectivesquared member 52 to the turret 6 of the block 5. - In this way, in the assembled configuration of the
device 50, as can be seen for example inFig. 7 , the squaredmembers 52 are retained with theirappendages 54 on respective sides of the turret 6 provided with anaperture 11, while theplates 53 of said squaredmembers 52 extend along respective sides of the turret 6 without apertures in a substantially orthogonal position one in relation to the other and with the plate 7 of the block 5. - The block 5 and the squared
members 52 are preferably in a metal material, in particular stainless steel, or materials that are easily formed, such as zamac, aluminium and the like. - In accordance with one aspect of the present invention, the position of attachment of each squared
member 52 on the block 5 can be advantageously adjusted in two substantially perpendicular directions (longitudinal and transversal directions with reference to the longitudinal extension of the turret 6) by loosening the attachment screws 56 so as to slide theappendages 54 in the direction of sliding of the nuts 58 in thelongitudinal guides 59 in the turret 6 and/or slide theappendages 54 along the extension of theslit 55, then again tightening the attachment screws 56 until theshank 57 abuts against a wall of the block 6 inside theslot 10. - The device for resting and
support 50 comprises moreover aremovable covering member 60 for the turret 6, preferably in a plastic material, to hide from sight theappendages 54 of the squaredmembers 52 and the rear side of the turret 6. In particular said coveringmember 60 compriseswalls 61 substantially orthogonal one in relation to the other and a pair ofdowels 62 formed in one piece on one of saidwalls 61 which engage removably in correspondingholes 63 formed on the rear side of the turret 6. - As regards the installation of the
support device 50 with thelock 1 according to the invention, the squaredmembers 52 are glued with theplates 53 against the respective glass panels of the frame of a showcase, in the example a lateral panel 64 (side or shoulder) and a lower (or upper)panel 65 respectively, in proximity of the front ends intended to form an angle (corner) between said panels. - The attachment is made by applying an adhesive on the
plate 53, then applying the squaredmember 52 with theplate 53 in pressure contact against a predefined front end zone of the respective panel and finally hardening the adhesive by means of irradiation with ultraviolet rays coming for example from a UV lamp. - At this point (
Fig. 6 ) theglass panels lateral apertures 11 of theslot 10 of the block 5. Tightening of thescrews 56 finally allows attachment of the squaredmembers 52 to the block 5 and therefore maintaining of thepanels Fig. 7 ). - Advantageously, in the case of inaccuracies of gluing of the squared
members 52, or in the case of assembly inaccuracies, it is possible to remedy these inaccuracies at least partially by loosening the attachment screws 56, then sliding theappendages 54 in the direction of sliding of the nuts 58 in thelongitudinal guides 11 in the turret 6 and/or sliding theappendages 54 along the extension of theslit 55, until reaching the required reciprocal position of the panels, then again tightening the attachment screws 56. - At this point provision is made to cover the turret 6 with the
cover 60, inserting thedowels 62 of thecover 60 in theholes 63 formed on the rear side of the turret 6. In this way, as shown in particular inFig. 8 , thefirst portion 2 of thelock 1 according to the invention is associated with a portion of the frame of the showcase (angular end portion of theupper wall 65 and of the lateral wall 64) by means of thedevice 50 whereof it is an integral part. - The plate-shaped
member 21 of thesecond portion 3 of the lock 1 (previously assembled with its components) is also glued, separately, in the manner described above, to the internal surface of themovable glass panel 4 of the showcase in proximity of an appropriate corner of saidpanel 4 so as to be able to associate one with the other thesecond portion 3 and thefirst portion 2 of thelock 1 in the manner described above (Fig. 9 ). In this attachment care is taken to make thegripping handle 46 project from themovable panel 4 so as to facilitate opening of the showcase as described above. - In
Fig. 10 a portion of a showcase is shown, obtained by joining thelateral panel 64 and thelower panel 65 of the frame of the showcase in a substantially perpendicular position one in relation to the other by means of adevice 50 according to the invention and joining themovable panel 4 to the frame of the showcase by means of thelock 1. - It can be noted that the
device 50 according to the invention, in addition to guaranteeing the necessary rest and support for the panels of the frame of the showcase and the opening or closure of the showcase, has advantageously reduced overall dimensions and pleasing aesthetic impact thanks also to the presence of the coveringmember 60 which conceals from sight the underlying attachment members. - One main advantage of the lock according to the invention lies in its high properties of resistance to tampering given that it can only be opened using a magnet of appropriate power which can possibly be adjusted according to needs.
- Possible forcing of the lock according to the invention with a metal tool, such as for example a screwdriver, is very difficult and, in the case of application of the lock to a showcase and similar furniture, this necessarily entails forcing on the glass such as to cause breakage or splintering thereof with consequent evidence of tampering.
- It should be noted moreover that the magnets necessary for opening the lock according to the invention must have a high power and therefore they are special products made by specialized firms and very difficult for the public to find.
- Even if they were available in some way, they usually have considerable dimensions to ensure the power necessary for opening the lock (for example a cylindrical magnet can have dimensions of 50 mm in diameter and 30 mm in height) and therefore are difficult to conceal, thereby making it difficult to perform any fraudulent actions.
- Further advantages of the lock according to the invention lie in its simple and economical production and in the ease of assembly which advantageously does not require any type of work on the glass such as cutting, drilling, etc.
- Another main advantage lies in the possibility of integrating the
lock 1 in a device for the resting and the support of glass panels in a perpendicular position one in relation to the other. - In the case of a device for the resting and support of glass panels in a perpendicular position one in relation to the other such as that of the invention and described above, the further advantage is obtained of being able to remedy possible inaccuracies of gluing of the block or of the squared members to the respective panels and/or inaccuracies of assembly by means of a simple adjustment of the attachment of the squared members in relation to the block.
- It should be noted advantageously that this adjustment is possible in the device according to the invention for each squared member in two substantially orthogonal directions.
- Another advantage of the device according to the invention lies in its efficacy in supporting glass panels also of considerable thickness (for example 6-8 mm).
- Another advantage of the device according to the invention lies in its reduced overall dimensions and in the versatility of use with panels responding to even very different needs and functions. Moreover its final appearance (cube shape) without projecting parts allows the device according to the invention to achieve a quality aesthetic appearance.
- Finally, a last advantage of the device according to the invention, no less important than the previous ones, lies in the ease of manufacture, which allows the possibility of production on a large scale and with low costs.
- The person skilled in the art may make numerous changes and variants to the lock and to the device according to the invention described above, moreover all coming within the sphere of protection of the following claims.
