Abstract
Description
- This invention relates to a shock absorbing device for sliding panels and doors.
- More in particular, this invention relates to a device as defined above, especially suitable for sliding panels of furniture, doors and closing panels in general.
- As is known, especially in the manufacture of furniture, the solution that envisages sliding rather than outwards projecting opening panels is widely used; it is an appreciated type as it limits the overall dimensions of furniture and moreover, for the fact that no hinges that could alter the overall appearance remain visible.
- Sliding doors that are used for the partition of rooms are also appreciated for the same reasons and also for the fact that once opened, they can be hidden in spaces created between adjacent walls.
- Doors and panels are provided with top and bottom carriages sliding along section bars fixed to the furniture frame during the manual movement for opening or closing.
- During these operations it often happens that the user pushes the panels or doors in a too strong manner, with the result that they reach the travel end in opening or closing violently colliding with the vertical abutment stop.
- Situations of this type can cause serious drawbacks, since the carriages may exit from the respective guides and get damaged; especially very high furniture panels, thus very heavy, could detach at the top part of the piece of furniture itself, with the risk of falling on the ground or colliding with the opposite wall.
- In the attempt to obviate this drawback, travel end stopping devices have been devised for sliding panels provided with elastic or shock absorbing means, suitable for slowing down the travel thereof. Such devices typically comprise one or more silicone pistons, cooperating with helical springs acting in towing on the panel or on the door, and however they have an important drawback. In fact, it has been proved that said known devices are only effective with light panels and doors, the height whereof is therefore limited. On the other hand, in the case of panels or doors extending at full height, which sometimes also have a mirror, the traditional devices alone are not capable of carrying out a suitable shock absorbing function and therefore require a considerable care by the user during the movement of the panels and doors themselves. In order to meet this requirement, said devices are sometimes provided with additional members suitable for increasing the shock absorbing effect, for example composed of braking gears combined with toothed cursors or the like, or of greater size pistons; however, a solution of this kind implies an unavoidable increase of production costs, as well as of the overall dimensions that make the installation of the devices as a whole more difficult.
- The object of this invention is to obviate the disadvantages mentioned hereinabove.
- More in particular, the object of this invention is to provide a shock absorbing stopping device for sliding panels or doors which allows obtaining a suitable shock absorbing effect especially on panels of large weight and size.
- A further object of the invention is to provide a shock absorbing stopping device which comprises a limited number of components and is therefore of limited overall dimensions for an easy and quick installation thereof.
- A further object of the invention is to provide the users with a shock absorbing stopping device for sliding panels and doors suitable for ensuring high level of resistance and reliability over time, also such as to be easily and inexpensively constructed.
- These and other objects are achieved by the shock absorbing stopping device for sliding panels and doors of this invention according to claim 1.
- The construction and functional features of the shock absorbing stopping device for sliding panels and doors of this invention will be better shown in the following detailed description, wherein reference is made to the annexed drawing tables showing a preferred and non-limiting embodiment thereof, wherein:
-
figure 1 shows a schematic exploded view of the shock absorbing stopping device for sliding panels and doors of this invention; -
figure 2 shows a schematic perspective view of the same device in the position corresponding to the closed position of the panel or door; -
figure 3 shows a schematic perspective view of the same device in the position corresponding to the open position of the panel or door; -
figures 4 and 5 show a schematic front view of the device of this invention combined and cooperating with a conventional carriage fixed to the panels; -
figure 6 shows a schematic perspective view of the shock absorbing stopping device of this invention in the configuration referred to the specific use thereof on sliding doors; -
figures 7 to 9 shows schematic side views of as many operating steps of the shock absorbing stopping device offigure 6 . - With initial reference to
figures 1 to 6 , the shock absorbing stopping device for sliding panels and doors of this invention, globally indicated with 10 atfigure 2 , comprises a plate shaped support orfooting 12, made of metal, plastic or other suitable material and of substantially rectangular shape, whereon atubular container 14 for a shock absorbing means is arranged; the said latter is advantageously composed of a silicone orair piston 16. Thetubular container 14 is arranged in the central-rear part of thefooting 12 and surmounts ashaped centring base 18 made integral with the footing itself. Thebase 18 comprises one ormore holes 20 for asmany screws 22 and relevant nuts 22' for fixing thedevice 10 in a cavity of a metal section bar (not shown) wherealong conventional carriages fixed to the panels slide. Thecontainer 14 defines an opening 14' of a longitudinally extended seat wherein thepiston 16 is arranged, fixed in the seat itself in a known manner. The stem 16' of thepiston 16 develops, when it is exposed, in the direction of the front side of thefooting 12 and the free end thereof is connected to a guidingcursor 24. Thecursor 24 is preferably composed of a plate substantially shaped as an "L" and comprises apin 26 suitable for sliding in alinear slot 28; saidslot 28 is obtained along akerb 30 that makes up the extension of thecentring base 18 of thefooting 12 and develops parallel to the footing itself. Thekerb 30 is made integral with said footing, relative whereto it develops orthogonally, reaching the front end thereof; in such position, thekerb 30 defines a rounded profile. - The
cursor 24 is connected to a side of thekerb 30 with interposition of acam 32; said cam has a basically "T" shaped inclined profile and is provided withopposite top 34 andbottom 36 recesses. Aplate 38 is arranged on the opposite side of thekerb 30 provided with a plurality ofholes hole 40, made at the back end facing theshaped base 18, seats apin 46 that crosses theplate 38, theslot 28, thecam 32 and thecursor 24. To this end, thecam 32 is provided with ahole 48 and thecursor 24 with ahole 50. Thepin 46 protrudes by a limited extent both from theplate 38 and from thecursor 24 and constitutes the hooking means of ahelical spring 52. - The opposite ends of
pin 46 are provided with agroove 54 for said spring, which advantageously is bent on itself as a "U" about the rear end of theshaped base 18. - In order to keep the
spring 52 into position relative to thefooting 12, it is envisaged that thetubular container 14 comprises two integral andopposite sleeves 56 of suitable length, wherein the spring is inserted before coupling the ends thereof to thepin 46. - A pair of
rivets 58, inserted in theholes plate 38, crosses theslot 28 and thebottom recess 36 of thecam 32 to engage intocorresponding holes cursor 24; therivets 58 thus compact theplate 38, thecam 32 and thecursor 24 to each other, while leaving freedom of movement to said cam that can pivot, as schematised atfigures 4 and 5 . Said cam comprises arivet 64, inserted in across hole 66, suitable for sliding along the top edge 30' of thekerb 30. - The
device 10 as a whole is suitable for being inserted and fixed, through thescrews 22 and the nuts 22', inside a known section bar wherein the conventional carriages for example fixed to the furniture panels (not shown) slide. Atfigures 4 and 5 , said carriages are schematised with 68 and comprise asupport 70 suitable for cooperating with thecam 32. The function of thedevice 10 in fact is to hook thecarriage 68 fixed to the panel and gradually lead the latter to the end of travel. - The progressive approach effect of the panel to the travel end thereof is determined by the synergy between the
spring 52 and thepiston 16. -
Figure 4 showsdevice 10 in the position corresponding to the open position of the panel. Thestem 22 of thepiston 16 is totally exposed and thespring 52 is tensioned, since the assembly composed of theplate 38, thecam 32 and thecursor 24 is arranged at the front end of thekerb 30; therivet 64 of thecam 32 has passed over the bottom end with rounded profile and the cam itself is lowered in the front side. - When the
carriage 68 of the panel abuts with thesupport 70 thecam 32, the latter pivots by the effect of the thrust received which leads therivet 62 to rise along the top edge 30' of thekerb 30. Thecam 32 engages with thesupport 70 through a front tooth 32' of the cam itself and at that point, the shock absorbed towing step carried out bydevice 10 towardscarriage 68, and thus the panel connected thereto, begins. Thespring 52 retracts and pulls backward the set composed of theplate 38, thecam 32, engaged with thecarriage 68, and thecursor 24 and in this step, it meets the resistance of thepiston 16 whosestem 22 abutted by thecursor 24 retracts progressively. Thespring 52 is sized so as to produce a suitable towing force and in parallel, thepiston 16 is sized to oppose thespring 52 and gradually approach thecarriage 68 to the end of travel. - On the other hand, when the panel opens the
spring 52 becomes tensioned and extends, thestem 22 ofpiston 16 exposes and thecam 32 moves at the front end of thekerb 30; therivet 64 passes over the rounded end of the kerb itself and causes the disengagement between thecam 32 and thesupport 70 ofcarriage 68. -
Figures 6 to 9 illustrate the device of this invention in an operating condition especially suitable for sliding doors for the partition of rooms. - According to this configuration, the
device 10 is upturned relative to the previous solution and is combined with acarriage 72, substantially known per se, fixed with ashaped plate 74 to the top side of the sliding door, not shown. Thedevice 10 and thecarriage 72 are inserted in ametal section bar 76 of substantially known type that defines twoopposite seats seat 78 located at the top receives thedevice 10 that is fixed therein in suitable position with screws or equivalent retaining members, whereas theseat 80 located at the bottom constitutes the rectilinear extended cavity wherein thecarriage 72 slides and wherefrom the same protrudes at the bottom through a longitudinally extendedslit 84 of said section bar. Said latter is constrained in a known manner to the support frame of the sliding door. Thecam 32 of thedevice 10 protrudes downwards in the direction of thecarriage 72, which is provided with ashaped projection 86 suitable for abutting and pivoting thecam 32; such pivoting leads the front tooth of thecam 32, indicated with 32', to insert in a recess 34' obtained on thecarriage 72, so that the latter as a whole is hooked and subject to the shock absorbed towing ofdevice 10, with the same methods described before with reference to wardrobe doors.Figure 7 , in particular, shows thecam 32 in two positions; in the front side of said figure, thecam 32 is shown in the moment it is abutted by thecarriage 72 that causes the pivoting thereof and leads the tooth 32' to insert in the recess 34'. In the back side of the same figure, wherein for simplicity the representation of thecarriage 72 has been omitted, thecam 32 is illustrated in the position it reaches subsequent to the retraction imposed by thespring 52, a retraction that also determines the return of thestem 22 of theshock absorbing piston 16. The horizontal position of thecam 32 is such since the tooth 32' thereof is engaged in the recess 34' of thecarriage 72, which has reached the end of travel in the opening step of the sliding door. - The two different conditions indicated above, of hooking the
carriage 72 and of the complete retraction thereof with reaching of the travel end, are respectively illustrated atfigures 8 and 9 . - As can be noticed from the above, the advantages achieved by the invention are clear.
- The shock absorbing stopping device for sliding panels and doors of this invention allows moving both the furniture panels and room partition doors, even very heavy, in a gradual manner, avoiding violent shocks or abutments with the travel end. The provision of using a single
helical spring 52 bent as a "U" which realised a calibrated towing force along the opposite sides of thekerb 30 is especially advantageous. - Moreover, said device is very compact, easy to seat in the section bar seats, and inexpensive to make considering the limited number of components thereof.
- Even if the invention has been described with particular reference to an embodiment thereof, made by way of a non-limiting example, several changes and variations will appear clear to a man skilled in the art in the light of the above description.
- This invention therefore is intended to include any changes and variations thereof falling within the spirit and the scope of protection of the following claims.
