Definitions

• the present invention generally relates to devices or systems for sliding elements for sliding doors.
• Hanging sliding doors typically involve a set of upper and lower rollers that slide through lower and upper tracks, respectively, where the lower rollers are often located below the lower track so as to engage therewith from below.
• a patent no. US4120072 discloses an apparatus for supporting and drivingly opening and closing an overhead single-panel door such as a garage door.
• the apparatus includes drive rollers protruding from the plane of the door at respective opposite upper corners thereof, which drive rollers are bearingly supported by a plate member attached to the door. These drive rollers are supported from underneath and in driving contact with fixed guide tracks arranged at the building accommodating the door.
• a bearing bracket is rotatably supported at the drive roller axles, which bearing bracket in turn supports a pair of counterpressure rollers
• the counterpressure rollers are spaced from one another in the direction of travel of the guide roller at respective opposite sides of a line through the axle with the drive roller and extending
• an additional spring support system is provided between the drive roller and the bracket supporting the drive roller axle and the door, so as to provide an additional biasing force in the downward direction on the drive roller.
• the roller applies pressure downwardly over the track since it engages the track from above.
• This solution is for keeping engagement by applying spring force hanging from above forcing the lower part of the roller to engage the upper part of the track, where the lower part of the track thereby engages a counterpessure roller.
• a patent No. GB 1343896 discloses a sliding door assembly that comprises a door slidable between upper and lower sets of horizontal axis rollers mounted on the side of a post.
• One roller 4 is driven by a shaft (17, Fig. 3).
• An eccentric sleeve (5) partially around the drive roller carries a radial arm (19, Fig. 4) which is spring biased, so that the sleeve urges the roller into engagement with the door.
• Rollers 13 have concave surfaces to guide the door.
• Further rollers 10, 11 are provided on a second post 9 with a stop 12.
• a screw is connected to a spring, the spring being connected to the eccentric sleeve to pull the sleeve down and thus force the drive roller upwards to maintain contact with a bottom horizontal edge of the door.
• a patent No. US4064593 discloses a supporting roller assembly for a sliding door that has a downwardly spring loaded guide track engaging roller supported for vertical floating movement by a mounting bracket containing a limited stop plunger which is spring loaded downwardly against the roller carrier.
• the bracket is slotted and carries a clamp screw accessible from the side of the door for clamping the bracket firmly about the plunger to secure the plunger in a fixed position for limiting upward movement of the guide roller against the action of its spring.
• the movable door panel is supported at its bottom on a track extending along the bottom of the door frame by means of roller assemblies mounted within a downwardly opening channel along the lower edge of the door panel.
• Each roller assembly has a peripherally grooved roller which rides in the track and is supported for vertical floating movement on a mounting bracket which is fixed within the bottom door channel.
• the roller carrier is spring loaded downwardly toward the track so as to yieldably retain the roller in proper guiding contact with the track in the event that the sliding door panel is inadvertently elevated away from the track during opening and closing movement thereof.
• an engagement mechanism of a hanging sliding door of a compartment such as a closet having a lower track and an upper track for the sliding door to slide therethrough
• the engagement mechanism comprises: (i) at least one guide roller for rolling along the lower track; (ii) a connector for connecting the engagement mechanism to the respective sliding door, wherein the connector comprises a supporting portion and an extended portion allowing holding the roller at a predefined distance from the respective sliding door; and (iii) an elastic member such as a coiled spring, for instance, connected to the roller in a manner that allows the roller to move along an axis of the elastic member that is substantially perpendicular to the sliding door tracks.
• the extended portion comprises a holding member for holding the elastic member there- above in a manner that allows the elastic member to apply force from below the roller towards the lower track located above the roller for maintaining engagement between the roller and the lower track throughout the sliding movement of the sliding door.
• the extended portion comprises an opening and a protruding member enabling to hold the coiled spring from below thereby allowing flexibly pressing the roller to the lower track from below.
• the roller connects to the extended portion via a fastening mechanism configured to fasten the roller to the extended portion in a manner in which the roller is positioned at a distance from the extended member.
• the extended portion comprises an angular structure comprising (i) a first portion that angularly connects to the supporting portion, where the supporting portion connects to the sliding door, and (ii) a second portion angularly connected to the first portion.
• the angle between the first portion and the supporting portion may be substantially straight (90°) and the angle between the first portion and second portion may also be substantially straight.
• the engagement mechanism further comprises an adjustment mechanism for allowing fine adjusting of the location of the engagement mechanism in respect to the door.
• Fig. 1 shows an exploded view of an engagement mechanism for hanging sliding doors, according to some embodiments of the present invention.
• FIG. 2 shows a frontal isometric view of the engagement mechanism, according to some embodiments of the present invention.
• FIG. 3 shows the engagement mechanism engaging a lower track of a sliding door, according to some embodiments of the present invention.
• Fig.4 shows the engagement mechanism engaging a lower track of a sliding door in a close-up view, according to some embodiments of the present invention.
• the present invention in some embodiments thereof, provides an engagement mechanism for hanging sliding doors of compartments such as closets, cupboards and the like.
• the engagement mechanism is configured to support the sliding movement of a roller such as a wheel or a spherical bearing, allowing the lower track, for compartment- sliding door configuration in which the lower track of the compartment is designed to be located above the roller.
• hanging sliding door refers to a sliding door that covers the outer rim of the compartment for esthetical reasons to allow only viewing the sliding doors from a frontal view of the compartment, where the compartment's frame is hidden by the sliding door(s) meaning that the height of the sliding door(s) is either equal or higher than the height of the compartment frame.
• Known in the art hanging sliding doors are usually configured as "top hung" sliding doors, in which the sliding door is hung from above by trolley hangers. In this configuration the entire weight of the door is carried by the top hangers from above.
• the present invention allows additional or alternative support of the door's weight from below using one or more lower sliding tracks of the compartment, since it offers an engaging mechanism that allows keeping each roller of one or more of the sliding doors engaged with its respective lower track (e.g. just the inner sliding door or also the outer sliding door). This allows the weight of the respective sliding door to additionally or alternatively be carried by lower components of the compartment - such as by a lower track thereof engaging the roller of the engagement mechanism from below.
• the engagement mechanism includes: (i) at least one roller for rolling along a lower track; (ii) a connector for connecting the engagement mechanism to the respective hanging sliding door, where the connector includes a supporting portion, which connects to the sliding door and an extended portion, which connects to the roller; and (iii) an elastic member such as a coiled spring, which elastically connects to the roller in a manner that allows the roller to move along an axis of the elastic member that is substantially
• the extended portion includes a holding member for holding the elastic member there-above in a manner that allows the roller to apply force from below towards the lower track of the compartment located above the roller for maintaining engagement between the roller and the lower track throughout the sliding movement of the sliding door.
• the engagement mechanism 100 includes a connector 110 for connecting thereof to the sliding door that includes a supporting portion 115a, and an extended portion 115b.
• the supporting portion 115a is configured to allow connecting thereof to a lower portion of the respective sliding door e.g. by screwing the supporting portion 115a to a back side lower portion of the sliding door through a designated groove 117 in the supporting portion 115a of the connector 110.
• the engagement mechanism 100 also includes a wheel guide roller 20 and a coiled spring 122 elastic member.
• the spring 122 provides the roller 20 with the ability to move along a vertical axis "z" (see Fig. 1) substantially perpendicular to the sliding movement of the roller 20 and sliding door, in response to "irregularities" of the lower track.
• These irregularities may be, for example, if the lower and upper tracks of the compartment are not parallel to a very high accuracy level in case the compartment system includes upper tracks as well when the lower track is not leveled enough and/or has bumps thereover. This will be further elaborated in the description of Figures 3-4 showing the lower track of the compartment.
• the extended portion 115b includes an opening 121a having a protruding member 121b at its bottom edge for holding the coiled spring 122 thereover from below.
• the roller 20 includes an inner groove 21 for receiving a protruding lower track type for sliding thereover by rolling.
• Figures 1-2 also show how the roller 20 is held by the connector 110 extended portion 115b by having a screw 25 inserted to the extended portion 115b through it opening 121a and fastened thereto through a movable connecting member 22 that attaches to the outer surface of the extended portion 115b, where the screw 25 is inserted through a designated perforation of the movable connecting member 22 and through the opening 121a and be fastened to the extended portion 115b by using a nut 24 and optionally also one or more O-rings 23 to reduce friction therebetween.
• the coiled spring 122 is held from below and therefore the lower protruding member 121b serves as a lower fixation point of the coiled spring 122 allowing the spring 122 to move along the "z" axis to contract or to stretch, in response to the vertical movements of the roller 20 when moved along the lower track of the respective compartment.
• the engagement mechanism 100 may also include an adjustment mechanism 30 located at the supporting portion 110 of the connector 110.
• the adjustment mechanism 30 is configured to allow adjusting the location of the entire connector 110 in respect to the edge of the sliding door and the tracks of the door (the lower track and optionally also the upper track) by including: (i) a first adjustment mechanism including a movable member 33 and an adjustment member 32 (e.g.
• an elastic member such as another coiled spring 31 stretched along a vertical axis of the connector 110 allowing fine adjustment of the connector 110 location along the vertical axis by enabling to contract/stretch in respect to vertical movements of the sliding door it connects to.
• roller 20 and the spring 122 are not located in the same planes - meaning that the roller 20 is held in a slightly distant position in respect to the coiled spring 122.
• the connection of the roller 20 to the connector 110 through the movable connecting member 22 allows the coiled spring 122 to vertically move in response to the roller's 20 vertical movements.
• the coiled spring and roller may be located one above the other over the same plane so that they share the same vertical axis.
• multiple rollers can be connected (through one or more connectors) to the same sliding door each connected to a different elastic member such as a coiled spring.
• the roller 20 includes a groove 21 for receiving and engaging a "protruding lower track” such as protruding lower track 50a, as illustrated in Fig. 4.
• the roller can include a substantially flattened outer rolling surface instead of the groove as described above.
• the lower track that should engage this roller is a "receptor lower track” (Not shown) configured to receive and enclose the roller therein. In most hanging doors protruding tracks are used for esthetical reasons.
• FIG. 3-4 schematically illustrating how the engagement mechanism 100 as described in respect to Figures 1-2 engages an outer protruding lower track 50a of a closet along which the roller 20 is to roll, where the engagement mechanism 100 is connected to an inner sliding door 200a of the closet.
• the closet in this example, has two sliding doors: the inner sliding door 200a and an outer sliding door 200b located in a manner that enables the doors 200a and 200b to slide one passed the other as they are located at two different parallel planes.
• the outer protruding lower track 50a engages the groove 21 of the roller 20 of the engagement mechanism 100 for supporting and sliding of the inner sliding door 200a.
• Another roller 20b having a groove 21b therein engages an inner protruding lower track 50b for supporting and sliding the outer sliding door 200b.
• the outer and inner protruding lower tracks 50a and 50b are connected (may be integrally connected) to one another and are parts of a tracks frame-structure 50 that connects to the closet frame.
• the frame-structure 50 can be a profile made of ridged materials such as metal or plastic that connects to the frame of the compartment (e.g. closet frame).
• the coiled spring 122 of the engagement mechanism 100 allows flexibly carrying the load of the inner sliding door 200a thereupon, since it engages the outer protruding lower track 50a from below, where slight vertical movements occurring when the inner sliding door 200a is slides through are
• the engagement mechanism as described above allows overcoming slight errors in alignment of the lower and/or upper tracks of the compartment while still allowing the roller to roll through the track as well as to engage the track throughout the sliding movement preventing the lower track engaging the roller of the engagement mechanism from being thrown out of the roller groove or from the roller from being thrown out of the track (depending on engagement mechanism configuration) with any misalignment of the lower and optionally upper track or encounter with obstacles in the track(s) such as dirt of misconfiguration of the track in one or more locations thereover.
