Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. In the following description, the words indicating the orientation have been given by way of illustration only, and it is to be understood that they do not limit the invention.
Fig. 1 shows a prior art interlockable drawer assembly, in which the side edges of the lower drawer are formed with laterally extending flanges that serve as rails 10 for the upper drawer, one of the rollers 20 of the upper drawer being supported on the rail 10. The end of the sliding rail 10 is provided with a protrusion 11, and in the process of opening the lower drawer from closing, the protrusion 11 abuts against the roller 20 of the upper drawer so as to drive the upper drawer to move. In the prior art, when the upper drawer is loaded with too many articles, at the moment that the protrusion 11 abuts against the roller 20, the roller 20 of the upper drawer may cross the protrusion 11 due to the large inertia of the upper drawer, so that the linkage of the upper drawer and the lower drawer is disabled. Meanwhile, due to the fact that the position of the protrusion 11 is fixed, after the lower drawer is opened, the opening size of the lower drawer and the opening size of the upper drawer are fixed, when the drawers are arranged at different heights, the sizes of the optimal relative openings of the upper drawer and the lower drawer can be changed, and therefore the optimal viewing effect of the drawer assembly in the prior art is difficult to achieve.
The application of the drawer assembly is wide, and the drawer assembly can be particularly used in furniture such as a wardrobe, a bookcase, a cabinet and a refrigerator.
Fig. 2 to 9 show a preferred embodiment of the present invention.
The drawer assembly in this embodiment includes a first drawer 100, a second drawer 200, a first protrusion 120, a first locking portion 210, and a first unlocking portion 400. The first drawer 100 can slide from the closed state to the open state along a first direction X (the first direction X can be a horizontal direction or an inclined direction, or even a vertical direction, the first direction X refers to a direction in which the drawer is directed from the position of the closed state to the position of the open state, and for convenience of description, the first direction X is exemplified as a horizontal direction below). The second drawer 200 is stacked above the first drawer 100 (when the first direction X is a vertical direction, "above" is understood to mean a side of the opening of the first drawer 100), and is slidable from a closed state to an open state along the first direction X. The open state and the closed state of the first drawer 100 and the second drawer 200 refer to states in which the two drawers are at respective open and closed extreme positions. The second drawer 200 is stacked above the first drawer 100, and only the relative positional relationship between the two drawers after both are in the closed state is shown, and the first drawer 100 and the second drawer 200 may be in contact with each other or may not be in contact with each other at all. In one embodiment, as shown in fig. 2, rollers are provided under the second drawer 200, and the rollers are supported on two side plates of the first drawer 100 and can freely slide on the two side plates of the first drawer 100. In another embodiment, the second drawer 200 may also be positioned entirely on the sliding track of the vertical side wall in the refrigerator freezer or freezer compartment, the first drawer 100 and the second drawer 200 being vertically free from each other.
The first protrusion 120 is disposed on the first outer side 110 of the first drawer 100 parallel to the first direction X and extends toward the second drawer 200. The first outer side 110 is an outer side of a vertically arranged side panel of the first drawer 100, in particular, an upper end face of the vertically arranged side panel of the first drawer 100 may also be referred to as the first outer side 110. That is, the first protrusion 120 may be disposed on a vertical surface of the vertically disposed side panel of the first drawer 100, and may also be disposed at an upper end edge of the vertically disposed side panel of the first drawer 100.
The first locking portion 210 is disposed at a second outer side 220 of the second drawer 200 parallel to the first direction X, i.e., the first locking portion 210 is disposed on an outer surface of a vertically disposed side plate of the second drawer 200 and disposed on the same side as the first protrusion 120. The first locking portion 210 has a locked state and an unlocked state. When the first locking portion 210 is in the locked state, the first protrusion 120 may abut against the first locking portion 210 along with the process of sliding the first drawer 100 from the closed state to the open state, and push the first locking portion 210 to drive the second drawer 200 to slide toward the first direction X. When the first locking portion 210 is in the unlocked state, the first protrusion 120 cannot push the first locking portion 210. That is, when the first locking portion 210 is locked, the first locking portion 210 and the projection of the first protrusion 120 in the horizontal direction have an overlapping portion, so that the first protrusion 120 cannot pass through the first locking portion 210.
The first unlocking part 400 is spaced apart from the second outer side 220, the first unlocking part 400 is fixed in position relative to the first drawer 100 and the second drawer 200 and cannot move, and the first unlocking part 400 may be specifically disposed on a vertically disposed inner sidewall of the refrigerator and configured to shift the first locking part 210 from a normally locked state to an unlocked state when abutting against the first locking part 210. That is, when the first unlocking unit 400 abuts against the first locking unit 210, the first locking unit 210 is in the unlocked state, and when the first locking unit 210 is not in contact with the first unlocking unit 400, the first locking unit 210 is in the locked state. The second drawer 200 slides from the closed state to the open state, and the first locking portion 210 slides to a position abutting against the first unlocking portion 400. In a specific embodiment, the first locking portion 210 may be a vertically slidable magnetic component, the first unlocking portion 400 also has magnetism, and when the first unlocking portion 400 approaches the first locking portion 210, the first locking portion 210 is attracted by magnetic force and moves upward (at this time, the first locking portion 210 is in an unlocked state), so that the first unlocking portion 400 does not generate position interference with the first protrusion 120 in the horizontal direction, and the first protrusion 120 may freely slide in the first direction X. When the first locking portion 210 is separated from the first unlocking portion 400, the first locking portion 210 falls due to gravity, so that the first locking portion 210 and the first protrusion 120 generate position interference in the horizontal direction, and the first protrusion 120 cannot pass through the first locking portion 210 and can only push the first locking portion 210 to slide together.
The specific motion process for the drawer assembly is as follows:
in the initial state, the first drawer 100 and the second drawer 200 are both in the closed state, and when a user needs to open all the drawers, the first drawer 100 can be pulled, and in the pulling process of the first drawer 100, the first locking portion 210 is in the locking state, so that the first protrusion 120 abuts against the first locking portion 210 and drives the second drawer 200 to slide towards the first direction X together in the process of sliding towards the first direction X. When the second drawer 200 slides until the first locking portion 210 abuts against the first unlocking portion 400, the first locking portion 210 is unlocked, the first protrusion 120 cannot push the first locking portion 210, and thus, in the process that the user continues to pull the first drawer 100, the second drawer 200 does not continue to move, and only the first drawer 100 moves towards the first direction X until the first drawer 100 is completely opened. After the above movement process, the first drawer 100 is completely opened, the second drawer 200 is partially opened, and the second drawer 200 covers a part of the opening area of the first drawer 100, so that both the first drawer 100 and the second drawer 200 are exposed out of only a part of the opening. It should be noted that, after the above actions are completed, when a user needs to take an article in the first drawer 100, the second drawer 200 may be manually pushed back to the closed state along the direction opposite to the first direction X (the drawer assembly in the prior art cannot achieve the above actions), and when a user needs to take an article in the second drawer 200, the second drawer 200 may be manually pulled out to the open state along the first direction X.
When the drawer assembly is installed, the movement stroke of the second drawer 200 can be controlled by adjusting the installation position of the first unlocking part 400, so that the relative opening sizes of the first drawer 100 and the second drawer 200 can be controlled. When the first unlocking part 400 is far from the first locking part 210, the second drawer 200 can be pushed out more by the first protrusion 120, and the opening thereof is larger. Specifically, an adjusting mechanism may be further provided, which enables the horizontal position of the first unlocking part 400 to be adjusted, so that the relative opening sizes of the first drawer 100 and the second drawer 200 after being opened can be adjusted after the drawer assembly is installed. In addition, in the present application, the horizontal sliding and the vertical bearing of the second drawer 200 are not affected by each other, so that the process of the first protrusion 120 pushing the second drawer 200 to move is more stable.
In a specific embodiment, as shown in fig. 5, the first locking portion 210 includes a movable gear 214, the axis of rotation of the movable gear 214 may be perpendicular to the first outer side surface 110, and the movable gear 214 is configured to be non-rotatable when the first locking portion 210 is in the locking state and to be freely rotatable when the first locking portion 210 is in the unlocking state. The first tab 120 pushes the first locking portion 210 by abutting the teeth of the loose gear 214. Further, a surface of the movable gear 214 facing the second outer side surface 220 is provided with a first stopper portion 2141. The first locking portion 210 may further include a locking member 213 disposed between the second outer side 220 and the movable gear 214, a second limiting portion 2132 is disposed on a surface of the locking member 213 facing away from the second outer side 220, and the second limiting portion 2132 prevents the movable gear 214 from rotating when abutting against the first limiting portion 2141. The first locking portion 210 further includes a first elastic element 212, and the first elastic element 212 generates an elastic force to make the first stopper portion 2141 abut against the second stopper portion 2132. The locking member 213 is configured to be pushed away from the movable gear 214 when the first unlocking portion 400 abuts the first unlocking portion 400, so that the movable gear 214 can rotate freely. That is, when the first unlocking portion 400 is not in contact with the first locking portion 210, the first elastic member 212 pushes the locking member 213 to make the first stopper portion 2141 abut against the second stopper portion 2132, so that the movable gear 214 cannot rotate, and the first protrusion 120 can push the second drawer 200 to slide by abutting against the teeth of the movable gear 214. When the first unlocking portion 400 abuts against the first locking portion 210, the first unlocking portion 400 presses the locking member 213, so that the first limiting portion 2141 is separated from the second limiting portion 2132, the movable gear 214 can rotate freely (i.e., the first locking member 213 is in an unlocked state), and when the first protrusion 120 pushes the teeth of the movable gear 214, the movable gear 214 rotates and finally passes through the movable gear 214.
The first stopper 2141 and the second stopper 2132 may be engaged with each other to limit the rotation of the movable gear 214, and the specific structure and number thereof may be set arbitrarily. In a specific embodiment, as shown in fig. 5, the first position-limiting portion 2141 includes a plurality of convex teeth, and each convex tooth is arranged in a circular array with the rotation axis of the movable gear 214 as a center, the second position-limiting portion 2132 includes a plurality of concave grooves respectively corresponding to the convex teeth, the plurality of concave grooves are arranged in a circular array with the rotation axis of the movable gear 214 as a center, and each convex tooth can be embedded in each concave groove in a one-to-one correspondence. Further, a circumferential cross section of the tooth around the rotation axis (which means a cross section taken by a columnar curved surface) is triangular, and the area of the circumferential cross section of the tooth further from the rotation axis is larger (that is, the larger the diameter of the columnar curved surface is, the larger the area of the cross section taken by the columnar curved surface is). Likewise, the circumferential section of the groove centered on the rotation axis is triangular, and the area of the circumferential section of the groove farther from the rotation axis is larger.
As shown in fig. 5, in an embodiment, the first locking portion 210 further includes a positioning member 211, the positioning member 211 is connected to the second outer side surface 220 and is formed with a positioning axis 2112 perpendicular to the second outer side surface 220 and a positioning protrusion 2111 extending away from the second outer side surface 220, and specifically, the positioning protrusion 2111 may be in a ring shape arranged around the positioning axis 2112 as shown in fig. 5. The locking member 213 has a sleeve 2131, and the sleeve 2131 is sleeved on the positioning shaft 2112. The movable gear 214 rotates about the sleeve 2131 as a rotation axis, and a surface of the movable gear 214 facing the second outer side surface 220 abuts against the positioning protrusion 2111 and is positioned by the positioning protrusion 2111. An abutting portion 216 is connected to an end portion of the sleeve 2131 far from the second limiting portion 2132, a second elastic member 215 is connected between the abutting portion 216 and a surface of the movable gear 214 away from the first limiting portion 2141, the second elastic member 215 generates an elastic force that enables the surface of the movable gear 214 facing the second outer side surface 220 to abut against the positioning protrusion 2111, and when the abutting portion 216 abuts against the first unlocking portion 400, the locking member 213 moves in a direction close to the second outer side surface 220, so that the first limiting portion 2141 is separated from the second limiting portion 2132. When the first locking portion 210 has the above-mentioned specific structure, in the unlocked state, the first unlocking portion 400 presses against the abutting portion 216 and further presses against the sleeve 2131, so that the locking member 213 is separated from the movable gear 214, and the movable gear 214 can rotate freely; in the locked state, the first unlocking portion 400 does not abut against the abutment portion 216, the lock member 213 locks the movable gear 214, and the movable gear 214 cannot rotate.
In one embodiment, the horizontal cross section of the first unlocking portion 400 parallel to the first direction X is trapezoidal, and the first unlocking portion 400 has an upper slope 410, an abutting surface 420 and a lower slope 430, and the abutting surface 420 is parallel to the second outer side 220. When the abutting portion 216 slides from the upper slope surface to the abutting surface 420, the abutting portion 216 is pushed to gradually displace toward the second outer side surface 220, so that the locking member 213 is gradually separated from the movable gear 214. When the abutment 216 is positioned against the abutment surface 420, the locking member 213 is completely separated from the loose gear 214. When the second drawer 200 is further pulled outward by the user, the first locking portion 210 goes over the downward slope and is separated from the first unlocking portion 400, and the locking member 213 again abuts on the movable gear 214. That is, in the process of sliding the second drawer 200 from the closed state to the open state, the abutting portion 216 moves toward the second outer side 220 first, and then moves away from the second outer side 220.
In one case, when a user pulls the first drawer 100 to an open state, and needs to take the articles in the first drawer 100, the user pushes the second drawer 200, which is half-opened, back to a closed state to completely open the first drawer 100, and when the first drawer 100 is retracted to the closed state, the first locking portion 210 is disengaged from the first unlocking portion 400, and the first locking portion 210 is in a locking state. When the first drawer 100 is retracted to the closed position after the article is taken out, the first protrusion 120 cannot be returned to the closed position because it is blocked by the first locking portion 210. In order to solve the above problem, as shown in fig. 7, in an embodiment, the first protrusion 120 has a rotation stroke from the first limit position to the second limit position within a preset angle, and the preset angle may be specifically 15 degrees to 60 degrees, for example, 15 degrees, 30 degrees or 40 degrees. The first protrusion 120 is connected to the third elastic member 121, and the third elastic member 121 gives a torque to the first protrusion 120, so that the first protrusion 120 is located at the first limit position. When the first bump 120 is pushed in the first direction X, it tends to rotate toward the second limit position. That is, in the direction reference shown in fig. 2, the first protrusion 120 can only rotate counterclockwise, and cannot rotate clockwise. Since the first protrusion 120 can rotate in the above direction, the first drawer 100 can still be reset even though the first locking portion 210 is in the locked state during the process of the first drawer 100 being retracted to the closed state.
The number of drawers of the drawer assembly is not limited to two, and in other embodiments, the drawer assembly may further include a plurality of drawers, and specifically, the drawer assembly may further include a third drawer 300, a second protrusion 230, a second locking portion 310, and a second unlocking portion 500.
