The present subject matter relates generally to refrigerator appliances and drawer slide synchronizers for refrigerator appliances.
Various types of consumer appliances are designed with pull-out compartment drawers. For example, a number of popular refrigerator styles have a freezer compartment with one or more pull-out drawers that span the width of the appliance and include storage baskets or bins. Examples of these refrigerators include Profile™ French door and Armoire style refrigerators from General Electric Appliances. The conventional pull-out drawers typically include side brackets that are mounted to slides of a slide mechanism that, in turn, has a base member mounted to the compartment liner.
Due to their substantial width, depth, and weight, the pull-out drawers are susceptible to misalignment between the sides when moving the drawer into and out of the appliance compartment, particularly if the door is grasped off-center and the pulling/closing force is applied non-parallel to the slide structure. This misalignment may lead to binding or “racking” of the drawer, which may make further movement of the drawer difficult and may also lead to an improper seal of the drawer in the closed position.
A known approach to minimize racking of the drawers is to synchronize the sliding movement of the opposite slide mechanisms with a rack and pinion system. Although the rack and pinion system is beneficial in minimizing the occurrence of racking, location of a shaft in the rack and pinion system is problematic in that it reduces the usable volume of the compartment for features such as bins, baskets, ice buckets, and so forth, especially when such devices are suspended above or below the drawer in a freezer compartment. In addition, rack and pinion systems can be noisy.
Accordingly, it would be desirable to provide an anti-racking system for pull-out drawers that occupies limited space below or behind the drawer while quietly reducing racking of the drawer.
The present provides a refrigerator appliance with a drawer slide synchronizer. The drawer slide synchronizer includes a first cable and a second cable. A first bearing is mounted to a first one of a pair of drawer slides, and a second bearing is mounted to a second one of the pair of drawer slides. The first and second cables contact the first bearing, and the first and second cables also contact the second bearing. Additional aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
In a first exemplary embodiment, a bottom-mount refrigerator appliance defines a vertical direction, a lateral direction and a transverse direction that are mutually perpendicular. The refrigerator appliance includes a cabinet that extends between a top portion and a bottom portion along the vertical direction. The cabinet also extends between a first side portion and a second side portion along the lateral direction. The cabinet further extends between a front portion and a back portion along the transverse direction. A chilled chamber of the cabinet is disposed at the bottom portion of the cabinet. A chilled chamber drawer assembly includes a chilled chamber door and a pair of drawer slides mounted to the cabinet at the chilled chamber of the cabinet. The drawer slides of the pair of drawer slides couple the chilled chamber door to the cabinet such that the chilled chamber door is translatable relative to the cabinet on the pair of drawer slides along the transverse direction. A drawer slide synchronizer couples the drawer slides of the pair of drawer slides together. The drawer slide synchronizer includes a first cable that extends between a first end portion and a second end portion.

As shown in
Each drawer slide of drawer slides 200 may be a full extension draw slide and may include a first or outer slide 210, a second or inner slide 220 and a third or intermediate slide 230. Outer slide 210 is fixed relative to casing 12. For example, drawer slides 200 may also include an outer slide bracket or housing 212. Outer slide housing 212 may be mounted to casing 12, e.g., with fasteners or any other suitable mechanism. In turn, outer slide 210 may be mounted to outer slide housing 212. Thus, outer slide 210 may be fixed relative to casing 12 via outer slide housing 212. In alternative exemplary embodiments, each drawer slide of drawer slides 200 may be a partial extension drawer slide and may include only outer slide 210 and inner slide 220, or each drawer slide of drawer slides 200 may include four or more total slides.
Inner slide 220 is mounted to front panel 26 of drawers 20, 22. Thus, inner slide 220 may be fixed relative to front panel 26 of drawers 20, 22. Inner slide 220 is received within intermediate slide 230, and intermediate slide 230 is received within outer slide 210. Intermediate slide 230 and inner slide 220 are slidable or moveable along the transverse direction T relative to outer slide 210 (e.g., and casing 12). In addition, inner slide 220 is slidable or moveable along the transverse direction T relative to intermediate slide 230. Thus, intermediate slide 230 may be slidable or movable relative to front panel 26 of drawers 20, 22. Ball bearings may extend between outer slide 210 and intermediate slide 230 may also extend between intermediate slide 230 and outer slide 210 in order to facilitate movement of inner and intermediate slides 220, 230 along the transverse direction T relative to outer slide 210. As may be seen in
Drawer slide synchronizer 100 includes a first cable 110, a second cable 120, a first bearing 130 and a second bearing 140. As may be seen in
Second cable 120 also extends between a first end portion 122 and a second end portion 124. First end portion 122 of second cable 120 may be mounted and disposed at or adjacent second side portion 46 of casing 12 and back portion 50 of casing 12, e.g. such that first end portion 122 of second cable 120 is fixed relative to casing 12 and positioned opposite first end portion 112 of first cable 110 about freezer compartment 18 along the lateral direction L. Conversely, second end portion 124 of second cable 120 may be mounted and disposed at or adjacent first side portion 44 of casing 12 and front portion 48 of casing 12, e.g. such that second end portion 124 of second cable 120 is fixed relative to casing 12 and positioned opposite second end portion 114 of first cable 110 about freezer compartment 18 along the lateral direction L. Like first cable 110, first and second end portions 122, 124 of second cable 120 may be disposed and fixed relative to casing 12 at opposite sides of freezer compartment 18, e.g., along both the lateral direction L and transverse direction T, and first and second end portions 122, 124 of second cable 120 may be spaced apart from each other, e.g., along both the lateral direction L and transverse direction T.
As may be seen in
Second end portion 114 of first cable 110 and second end portion 124 of second cable 120 may be mounted to a respective outer slide holder 212 of drawer slides 200, e.g., a front projection 216 on outer slide holder 212 at front portion 48 of casing 12. Front projection 216 may be positioned in front of outer slide 210, e.g., along the transverse direction T. In alternative exemplary embodiments, second end portion 114 of first cable 110 and second end portion 124 of second cable 120 may be mounted to a respective outer slide 210 of drawer slides 200, e.g., with front projection 216 formed on outer slide 210. In other alternative exemplary embodiments, second end portion 114 of first cable 110 and second end portion 124 of second cable 120 may be mounted directly to casing 12, e.g., with fasteners, clips, etc. in front of outer slide 210 along the transverse direction T.
First bearing 130 is mounted to a first one 202 of drawer slides 200. In particular, first bearing 130 may be fixed relative to front panel 26 of drawers 20, 22 on first one 202 of drawer slides 200, and first bearing 130 may move along the transverse direction T with front panel 26 of drawers 20, 22 during opening and closing of drawers 20, 22. Second bearing 140 is mounted to a second one 204 of drawer slides 200. In particular, second bearing 140 may be fixed relative to front panel 26 of drawers 20, 22 on second first one 204 of drawer slides 200, and second bearing 140 may move along the transverse direction T with front panel 26 of drawers 20, 22 during opening and closing of drawers 20, 22. First and second bearings 130 may be rotatable on drawer slides 200 in certain exemplary embodiments.
First and second cables 110, 120 each contact first bearing 130. For example, as shown in
Drawer slide synchronizer 100 assists with synchronizing motion of drawer slides 200 as drawer slides 200 shift between the retracted and extended configurations. For example, first and second cables 110, 120 and first and second bearings 130, 140 assist with synchronizing motion of drawer slides 200, e.g., such that inner slides 220 of drawer slides 200 translate along transverse direction at a common speed as drawer slides 200 shift between the retracted and extended configurations.
From the extended configuration shown in
A joint or connection 118 between cable segments 116 of first cable 110 may be positioned proximate second side portion 46 of casing 12. Conversely, a joint or connection 128 between cable segments 126 of second cable 120 may be positioned proximate first side portion 44 of the casing 12. Thus, connection 118 of first cable 110 and connection 128 of second cable 120 may be spaced apart from each other along the lateral direction L and may not contact or slide over first bearing 130 and/or second bearing 140 as drawer slides 200 shift between the retracted and extended configurations.
