Description

SYSTEM OF EJECTING A SLIDING DOOR

BACKGROUND

1. FIELD OF THE INVENTION

[0001] The present invention generally relates to sliding doors systems and more particularly to systems for ejecting sliding doors.

2. DISCUSSION OF RELATED ART

[0002] Sliding doors are commonly used in closets and compartments and make an easy and esthetic solution for opening and closing of closet doors. Sliding doors are usually connected to rollers or sliding members that can slide along upper and lower tracks installed at the closet lower and upper frame.

[0003] Since each track length is confined to the width of the closet, and since more than one sliding door is required for covering the open side of the closet, each doors usually slides along a different upper track and a different lower track where of the lower tracks and the upper tracks are located at a predefined distance from one another allowing the doors to slide through one another when opening or closing a section of the closet. This means that each door is installed at a different plane where the planes of the doors are parallel.

[0004] To allow the sliding doors to be installed at the same plane when the closet is closed, at least one of the doors must be ejected outwardly when opening the door to allow sliding of one of the doors along the track. Otherwise, the doors will block one another from sliding along the tracks.

SUMMARY

[0005] According to one aspect of the invention, there is provided a system of ejecting a sliding door of a closet. The system may comprise at least two ejection assemblies and at least one connecting mechanism, which connects one assembly to the other, where the ejection assemblies enable ejecting of the door.

[0006] According to some embodiments of the present invention, each ejection assembly may comprise a rail and a slidable member configured to slide along the rail, where the rail is operatively connected to the door. The connecting mechanism may allow applying a simultaneous ejection force upon the door at different locations of the door, allowing synchronizing the mechanical ejection of all ejection assemblies by connecting them to one another.

[0007] The rail in each assembly engages with the frame of the closet, where the assembly is connected to the door. This configuration allows ejecting the door outwardly from the closet frame by sliding the slidable member towards the distal end of the door, and retrieving the door inwardly by sliding the slidable member towards a proximal end of the door. Since the rails engage with the closet frame, the entire door is ejected upon movement of the slidable members of the assemblies in relation to their rails. Each of the ejection assemblies enables simultaneously ejecting and retrieving the door outwardly and inwardly from a plane that is substantially parallel to the door thereby enabling synchronized ejection at a plurality of locations of the door.

[0008] According to some embodiments of the present invention, the connecting mechanism may include a set of connectors such as rods operatively associated with the door handle thereby enabling simultaneously operating all ejection assemblies by a single rotation of the handle.

[0009] Alternatively, the connecting mechanism may include a hydraulic or pneumatic system including a pump and a tube set, where each of the ejection assemblies includes a piston connected to the pump. The piston may be connected to the slidable member thereby enabling moving the piston in and out to allow sliding the slidable member along rail to eject or retrieve the door.

DETAILED DESCRIPTION

[0011] The present invention, in some embodiments thereof, provides systems of ejecting a sliding door of a closet. Each system may comprise a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other, where the ejection assemblies enable ejecting of the door. [0012] According to some embodiments of the present invention, each ejection assembly comprises a rail and a slidable member configured to slide along the rail. The assembly is connected to the door. The connecting mechanism may allow applying simultaneous ejection forces upon the door at different locations of the door, allowing synchronizing the mechanical ejection of all ejection assemblies by connecting them to one another.

[0013] The rail in each assembly engages with the frame of the closet, where the assembly is connected to the door. This configuration allows ejecting the door outwardly from the closet frame by sliding the slidable member towards the distal end of the door, and retrieving the door inwardly by sliding the slidable member towards a proximal end of the door. Since the rails engage with the closet frame, the entire door is ejected upon simultaneous movement of the slidable members of the assemblies in relation to their rails, thereby enabling synchronized ejection at a plurality of locations of the door.

[0014] According to some embodiments of the present invention, the connecting mechanism may include a set of connectors such as rods operatively associated with the door handle thereby enabling simultaneously operating all ejection assemblies by a single rotation of the handle.

[0015] Alternatively, the connecting mechanism may include a hydraulic or pneumatic system including a pump and a tube set, where each of the ejection assemblies includes a piston connected to the pump. The piston may be connected to the slidable member thereby enabling moving the piston in and out to allow sliding the slidable member along rail to eject or retrieve the door.

[0016] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is applicable to other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. In other modules, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the teachings of the present disclosure.

[0017] Reference is now made to FIG. 1, which schematically illustrate a system 100 for ejecting a sliding door 500, according to some embodiments of the present invention. The system 100 may comprises four ejection assemblies 200 each connected at a different corner of the door 500 through a connecting member 250. The ejection assemblies 200 are connected to one another through a connecting mechanism 150.

[0018] As illustrated in Figures 1-3, each ejection assembly 200 comprises a rail 210 and a slidable member 214 configured to slide along the rail 210.

[0019] The ejection assembly 200 further comprises a connector 220, fastened to the slidable member 214 at one end through fastening means. The connector 220 includes a groove 221, which may be an opening enabling to receive a protrusion 232 of an interlocking member 230. The protrusion 232 is configured to movably interlock into the groove 221. The movable member 231 is connected to the connecting mechanism 150. This configuration, as illustrated in Figures 2-3, allows sliding the slidable member 214 along the rail 210 upon moving of the protrusion 232 along the groove 221. The protrusion 232 is moved along the groove 221 upon movement of the connecting mechanism 150, which operatively connects to the door handle (not shown). Therefore, a turning or rotating of the door handle allows sliding the protrusion 232 along the groove 221 and thereby allows sliding the slidable member 214 along the rail 210.

[0020] Alternatively, the ejection assemblies 200 and/or the connecting mechanism 150 may be operatively associated with at least one motor and an electronic control panel (whether remote or installed at the door 500) enabling to eject and retrieve the door 500 by controlling the motor. The motor may be operatively associated with one or more slidable members 214 allowing sliding thereof. [0021] As illustrated in Figures 1-3, the ejection assembly 200 further includes a roller 20, configured to slide along a track of the closet along an axis "x". The roller 20 is fastened to the slidable member 214 through any fastening means known in the art. The rolling direction of said roller 20 along the door track is angular to the sliding direction of the slidable member 214 along the rail 210. The sliding direction of the slidable member 214, as illustrated in Figures 1-3, is along an axis "z" perpendicular to "x" the sliding direction of the door 500. The sliding direction of the protrusion 232 along the groove 221 is angular to the sliding direction of the slidable member 214 and also to the sliding direction of the sliding door 500.

[0022] Once the door 500 is in an ejected position, in which the door is ejected outwardly, as illustrated in FIG. 3, the slidable member 214 is located at a distal end in relation to the door 500 and the protrusion 232 is located at a distal end in relation to the rail 210. In a closed position, in which the door is retrieved inwardly, as illustrated in FIG. 2, the slidable member 214 is located at a proximal end in relation to the door 500 and the protrusion 232 is located at a proximal end in relation to the rail 210.

[0023] According to some embodiments of the present invention, as illustrated in FIG. 1 , the connecting mechanism 150 comprises a first rod 151 A connecting two ejection assemblies located at two corners at a first side of the door 500 and a second rod 151B connecting two other ejection assemblies located at two other corners at a second side of the door 500. The connecting mechanism 150 further includes a rod-connecting assembly 50 for connecting the first rod 151A to the second rod 151B and for connecting to the door handle.

[0024] As illustrated in FIG. 1 , the rod-connecting assembly 50 may comprise a first connector 51, a second connector 52, a third connector 53 and a main axle 54. The first connector 51 pivotally connects to the main axle 54 at one end ant to the door 500 at another end. The second connector 52 pivotally connects to the main axle 54 at one end ant to the first rod 151A at another end. The third connector 53 pivotally connects to the main axle 54 at one end ant to the second rod 151B at another end. Since the first connector 51 connects to the door handle and to the main axle 54, it allows moving the axle 54 upon movement of the first connector 51, thereby allowing synchronized movement of the first, second and third connectors 51-53 upon manual rotation of the door handle.

[0025] The connecting mechanism 150 of each of the ejection assemblies 200 may further connect to the door 500 via at least one bracket 40, which may be a bearing or any other mechanism enabling movement of the rods with minimal friction.

[0026] According to some embodiments of the present invention, the door 500 is attached to profiles 30 framing the door at each side. The connecting member 250 of each ejection assembly 200 may be attached to one of the profiles 30 at the corner in which the ejection assembly 200 is installed, as illustrated in Figures 1-3.

[0027] To attach to the profile 30 the connecting member 250 may include protruding members 31 interlocking with corresponding openings at the profile 30.

[0028] Reference is now made to figures 4, 5A, 5B, and 5C, which schematically illustrate an ejection system 600, having ejection assemblies 200A, 200B, 200C and 200D which are similar to the assemblies as described in reference to Figures 1-3. The system 600 additionally includes a different connecting mechanism 160 which connects to the door 500 and to each of the ejection assemblies 200A, 200B, 200C and 200D. The connecting mechanism 160 includes two rods 161A and 161B each rod connects to two different ejection assemblies: the rod 161A connects ejection assemblies 200A and 200D which are located at one side of the door 500 and the rod 161B connects ejection assemblies 200B and 200C which are located at another side of the door 500. The connecting mechanism 160 additionally includes a connector 162 which connects the two rods 161A and 161B as well the two upper ejection assemblies 200A and 200B.

[0029] As illustrated in FIG. 5A, the connector 162 pivotally connects to the interlocking member 230 of each ejection assembly 200 A and 200B at each side of the connector 162. The connector 162 connects to a proximal end of the interlocking member 230 of ejection assembly 200A and to a distal end of the interlocking member 230 of the other ejection assembly 200B, thereby always positioned at an angle that is neither perpendicular nor parallel to the "x" axis of the door plane. The angular positioning of connector 162 provides an optimal leverage for ejecting the door 500 once a user pushes the door 500 outwardly for ejection thereof. In addition, the angular position of the connector 162 allows rotating one rod such as rod 161A in one rotation direction, while simultaneously rotating the other rod 161B in the opposite rotation direction, as illustrated in FIG. 5A.

[0030] As illustrated in Figures 4, 5A, 5B and 5C, the system 600 additionally includes a mode fixation mechanism including mode fixation assemblies 70. Each mode fixation assembly 70 is installed at a different ejection assembly 200 A- 200D. According to some embodiments of the present invention, as illustrated in FIG. 5A and FIG. 5B, the mode fixation assembly 70 includes two sets of roller stoppers a first roller stopper 72, and a second roller stopper 73. The first roller stopper 72 pivotally connects to the rail 210 through a fastener 71 in a retractable manner, using a retractable member such as a spring 75, where the spring 75 connects to the rail 210 at one end and to the fastener 71 at the other end through attaching members such as screws 76a and 76b. The spring 75 allows keeping tension for retracting the first roller stopper 72 to a closed retrieved position. Once the door 500 is in an ejected position, as illustrated in FIG. 5B, in which the first roller stopper 72 does not interlock (is "unlocked) with the second roller stopper 73 there is tension in the spring 75 enabling automatic mechanical retraction to a closed retrieved position, in which the roller stoppers b72 and b73 interlock. The fastener 71 is retracted into the closed interlocking position upon applying a slight force for retrieving of the door 500. The fastener 71 is pivotally and retractably connected to the rail 210 to allow rotation thereof around the "y" axis for enabling the first roller stopper 72 to interlock and unlock with the second roller stopper 73. This allows the door 500 to be positioned in two positions only: the ejected and the retrieved positions preventing the door 500 from being in a middle position therebetween.

[0031] Reference is now made to FIG. 6, which schematically illustrates an ejection system 100' for a sliding door 500, according to other embodiments of the present invention.

[0032] The ejection system 100' may include four ejection assemblies 200' and a connecting mechanism 150'. Each ejection assembly 200' including the same configuration of a connecting member 250', a sliding member 214' and a rail 210'. Each ejection assembly 200' may be installed at a different corner of the door 500 similarly to the installation described in Figures 1-3.

[0033] In these embodiments, the connecting mechanism 150' includes a strip, which may be made from elastic or non-elastic material such as rubber, fabric, etc. Each ejection assembly 200' includes a shaft 240, a fastening member 241, and a pulley 245.

[0034] The shaft 240 may be spirally furrowed serving as a male screw portion, where the fastening member 241 is a nut enabling to move along the shaft 240 by spirally screwing through it. Since the fastening member 241 is connected to the slidable member 214', it allows sliding the slidable member 214' once moved along the shaft 240.

[0035] As illustrated in Figures 7-8 the pulley 245 engages with the strip 150' and allows rotating the shaft 240 upon movement of the strip 150', thereby allowing the fastening member 241 to move along the shaft 240 upon rotation thereof.

[0036] According to some embodiments of the present invention, as illustrated in FIG. 9, the strip 150' further engages a handle pulley 51' which allows rotation of the strip 150' upon rotation of a door handle connected thereto. [0037] The connecting member 250' may be fastened to the profile 30 of the door 500 through protruding members 31 ' in a similar manner to that described in relation to Figures 1-3.

[0038] As illustrated in Figures 7-8, the ejection assembly 200' further includes a roller 20', configured to slide along a track of the closet along an axis "x". The roller 20' is fastened to the slidable member 214' through any fastening means known in the art. The rolling direction of the roller 20' along the door track is angular to the sliding direction of the slidable member 214' along the rail 210'. The sliding direction of the slidable member 214', as illustrated in Figures 7-8, is along an axis "z" perpendicular to "x" the sliding direction of the door 500. The fastening member 241 is also configured to move along the "z" axis.

[0039] Once the door 500 is in an ejected position, in which the door is ejected outwardly, as illustrated in FIG. 8, the slidable member 214' is located at a distal end in relation to the door 500 and the fastening member 241 is located at a distal end in relation to the door 500. In a closed position, in which the door is retrieved inwardly, as illustrated in FIG. 7, the slidable member 214' is located at a proximal end in relation to the door 500 and the fastening member 241 is located at a proximal end in relation to the door 500.

[0040] Reference is now made to FIG. 10, which schematically illustrates an ejection system 100" for a sliding door 500, according to additional embodiments of the present invention.

[0041] The ejection system 100" may include four ejection assemblies 200" and a connecting mechanism 150". Each ejection assembly 200" including the same configuration of a connecting member 250", a sliding member 214" and a rail 210". Each ejection assembly 200" may be installed at a different corner of the door 500 similarly to the installation described in Figures 1-3.

[0042] In these embodiments, the connecting mechanism 150" includes a tube set operatively connected to a hydraulic/pneumatic pump 50" enabling to pump liquid/air through the tube set 150" to allow moving the slidable members 214" for ejecting and retrieving of the door 500.

[0043] As illustrated in Figures 1 1-13, each of the ejection assemblies 200" further includes a piston 270 including a cylindrical member 271 and a piston member 272 ejecting in and out of the cylindrical member 271. The cylindrical member 270 connects to the tube set 150" and the piston member 272 connects to the slidable member 214" enabling to move the slidable member 214" upon ejection in and out of the cylindrical member 272.

[0044] The piston member 272 may be ejected in and out of the cylindrical member 271 along an axis "z" parallel to the sliding direction of slidable member 214" and perpendicular to the sliding direction "x" of the roller 20" along the track.

[0045] The pump 50" may be electronically operated using a control panel including operation input controllers such as operation buttons. The control panel may be installed at the door 500 or a remote panel.

[0046] The connecting member 250" may be fastened to the profile 30 of the door 500 through protruding members 31" in a similar manner to that described in relation to Figures 1-3.
