Description

TECHNICAL FIELD

[0001] The present application belongs to the field of storage devices, and particularly relates to a storage device with a lifting mechanism. BACKGROUND

[0002] Due to the height of the human body, it is inconvenient for a person standing on the ground to take and arrange articles in a storage space at a high position, such as an article in a cabinet layer rack at a height of 1.9 meters or more above the ground. In a commercial environment, although the space height is sufficient to accommodate a very high article storage cabinet, the goods placed at a high position can be displayed, but are inconvenient for the staff and customers to observe and take. The problem is particularly obvious for goods such as clothes, shoes, and hats displayed at a high position. In addition to the articles placed at a high position, the articles placed in a low position near the ground also require a person to crouch when observing and taking, and the operation is not convenient. It is even more difficult to bend over to check the articles in a storage compartment with a height of only 20 cm above the ground.

[0003] In view of the above problems, the existing auxiliary devices on the market generally include two types: one type is a storage cabinet or storage compartment that can be lowered downward by a telescopic mechanism, and the other type is a manual or electric clothes hanger that can be folded downward. However, these two types of devices still have the following problems:

[0004] 1. Each time the user needs to take or place articles in the lowerable storage cabinet or take or hang clothes on the foldable clothes hanger, the device needs to be moved forward and returned to the original position, which is time-consuming and troublesome.

[0005] 2. The height of the high-position storage position or the clothes hanger of these two types of solutions is limited, and the near-top space of the top storage cabinet cannot be fully utilized. The storage compartment in the near-top space with a height of more than 2.1 meters above the ground cannot be covered by the device.

[0006] 3. If the foldable clothes hanger is used to store seasonal clothes, the new seasonal clothes in the lower layer need to be replaced with the old seasonal clothes, which increases the operation process and is not convenient.

[0007] 4. Due to the limited application height, it is difficult to apply to the multi-layer display and storage of commercial exhibition hall high-wall cabinets.

[0008] 5. It cannot be applied to the near-ground storage space, and thus cannot solve the inconvenience of the need for a crouching action in the near-ground storage space. SUMMARY

[0009] In order to solve the above-mentioned defects of the prior art, the present application provides a storage device with a lifting mechanism, characterized in that:

[0010] It comprises left and right main guide rails 3, one main lifting frame 1, and at least one auxiliary lifting frame 2.

[0011] The main lifting frame 1 comprises left and right main lifting guide parts 11;

[0012] The main lifting guide parts 11 are provided with left and right main cantilevers 12 extending forward and left and right telescopic arms 14 extending forward; the left and right telescopic arms 14 are provided with load-carrying parts therebetween; under the drive of a transmission mechanism, the left and right telescopic arms 14 can be synchronously telescoped along the left and right main cantilevers 12 respectively;

[0013] The auxiliary lifting frame 2 comprises left and right auxiliary lifting guide parts 21, each of which can be synchronously lifted along the inner guide groove 31 of the main guide rail 3 under the drive of a transmission mechanism; the left and right auxiliary lifting guide parts 21 are provided with load-carrying parts therebetween;

[0014] When the telescopic arms 14 of the main lifting frame 1 are extended forward by a preset length, each of the main lifting guide parts 11 can be lifted between a preset high position and a preset low position along the outer guide groove 32 of the main guide rail 3 under the drive of a transmission mechanism, and meanwhile, the telescopic arms 14 of the main lifting frame 1 and the load-carrying parts therebetween can be lifted between a preset high position and a preset low position in front of the auxiliary lifting frame 2 along with the main lifting frame 1;

[0015] When the telescopic arms 14 of the main lifting frame 1 are extended forward by a preset length, the auxiliary lifting frame 2 can pass through the space between the main cantilevers 12 of the main lifting frame 1 up and down;

[0016] When the auxiliary lifting frame 2 is lifted to a preset high position and the main lifting frame 1 is lowered to a preset low position below the auxiliary lifting frame 2, the telescopic arms 14 of the main lifting frame 1 and the load-carrying parts therebetween can be retracted to below the auxiliary lifting frame 2;

[0017] When the auxiliary lifting frame 2 is lowered to a preset low position and the main lifting frame 1 is lifted to a preset high position above the auxiliary lifting frame 2, the telescopic arms 14 of the main lifting frame 1 and the load-carrying parts therebetween can be retracted to above the auxiliary lifting frame 2.

[0018] In order to increase the applicable height range of the device,

[0019] Preferably,

[0020] The auxiliary lifting frame 2 comprises an upper auxiliary lifting frame 2a and a lower auxiliary lifting frame 2b below the upper auxiliary lifting frame 2a,

[0021] When the telescopic arms 14 of the main lifting frame 1 at a preset high position are extended forward by a preset length, the upper auxiliary lifting frame 2a at a preset middle position can be lifted to a preset high position; the telescopic arms 14 of the main lifting frame 1 at a preset middle position and the load-carrying parts therebetween can be retracted to between the upper auxiliary lifting frame 2a and the lower auxiliary lifting frame 2b;

[0022] When the telescopic arm 14 of the main lifting frame 1 at the preset high position is extended forward by a preset length, the upper auxiliary lifting frame 2a at the preset middle position can be lifted to the preset high position, and the lower auxiliary lifting frame 2b at the preset low position can be lifted to the preset middle position; the telescopic arm 14 of the main lifting frame 1 at the preset low position and the load-carrying components therebetween can be retracted to below the lower auxiliary lifting frame 2b.

[0023] Obviously, the load-carrying components can be the clothes rod 4 or the storage cabinet 8.

[0024] The present application relies on the above-mentioned load-carrying components that can be exchanged in position up and down; the load-carrying components at the preset high position can be exchanged in position with the load-carrying components currently at the preset middle position according to the needs of the user, so that the load-carrying components originally at too high a position can be lowered to the preset middle position. Obviously, the preset middle position of the product belongs to the ideal operating height range most suitable for the user to access, thereby solving the problems existing in the prior art and achieving the basic inventive purpose.

[0025] According to the above technical features, when two auxiliary lifting frames 2 are used, even the storage space at the preset low position can be lifted to the preset middle position, so that the storage space at too low a position can also be lifted to the preset middle position, thereby solving the problem that the articles in the low-position space are difficult to observe and access, and further achieving the inventive purpose.

[0026] When the load-carrying component is a storage cabinet, preferably,

[0027] The device further comprises a fixed outer cabinet body 5,

[0028] The main guide rail 3 is installed on the back plate 53 of the outer cabinet body;

[0029] The main lifting frame 1 and the auxiliary lifting frame 2 are located between the left and right outer cabinet body side plates 51;

[0030] A front-moving frame 6 is arranged at the front end of the outer cabinet body 5; the front-moving frame 6 comprises left and right front-moving frame edge columns 61; the upper and lower ends of the front-moving frame edge columns 61 are respectively provided with rearwardly overhanging upper and lower insertion arms 62 and 63; the upper insertion arm 62 is inserted into the top portion 52 of the outer cabinet body by means of front-rear telescopic guide members, and the lower insertion arm is inserted into the bottom portion 54 of the outer cabinet body by means of front-rear telescopic guide members;

[0031] The left and right front-moving frame edge columns 61 are in vertical guide structure and are slidably connected with the front ends of the telescopic arms 14 of the main lifting frame 1, and can move forward and backward with the telescopic arms 14.

[0032] The inclusion of the forward-moving frame 6 resolves the gaps between the sides of each storage cabinet 81, 82 and the outer cabinet side panel 51, enhancing the overall appearance of the product. Furthermore, the forward-moving frame side post 61, which follows and assists in guiding the telescopic arm 14 of the main lifting frame 1 during its forward and backward movement and lifting motion, improves the reliable guiding and limiting function of the main lifting components and further prevents the main storage cabinet from tilting forward and falling during lifting. Simultaneously, it increases the user's visual sense of product safety.

[0033] In this document, the term "transmission mechanism" includes drive systems powered by motors, electric actuators, manual cranks, or manual push-pull components via transmission components such as wire ropes, chains, or timing belts.

[0034] The term "front" refers to the direction pointing towards the observer when viewing the parts shown in the referenced view, while the direction away from the observer is called "back". The terms "up", "down", "left", and "right" are based on the top, bottom, left, and right of the referenced view. The term "bottom" refers to the bottom of a specific part in the referenced view in the attached drawing, and "top" refers to the top of a specific part in the referenced view in the attached drawing.

[0035] The above-mentioned directional terms are only for the purpose of accurately describing the relative positional relationship of the various parts of the present invention, and are not intended to indicate or imply that the components referred to must have a specific orientation, or must be combined and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0036] The terms "preset high position," "preset middle position," and "preset low position" refer to the height positions or height limits that are set in advance during product design, based on the needs of different spatial applications and the requirements of product space height limitations.

[0037] The term "preset length" refers to the maximum extension required to avoid conflict with the auxiliary lifting frame, based on a pre-designed telescopic boom of the main lifting frame.

[0038] The term "vertical guide structure" refers to a sliding pair that matches the guide groove or protrusion on the side of the forward frame side post 61 and is installed on the side of the telescopic arm 14 or the main storage cabinet 81. This sliding pair should ensure that the forward frame side post 61 can move back and forth with the main storage cabinet 81.

[0039] The term "forward and backward telescopic guide member" refers to a telescopic guide member that can guide the forward-moving frame side column 61 to move only forward and backward, such as a three-section guide rail, or a pull-in pair composed of rods and cylinders.

[0040] More specific technical features and beneficial effects of the present invention will be described in further detail in the following embodiments with reference to the accompanying drawings. Attached Figure Description

[0070] Embodiment 1 of the present application is as shown in Figures 1 to 10 .

[0071] Referring to Figure 1 , the present embodiment is a wardrobe application scheme with three clothes rods 4 designed according to the principles of the present application. It adopts an outer cabinet body 5 with a height of 2.8 meters, and the back plate inside the outer cabinet body 5 is equipped with left and right main rails 3. Among them, the left side of the left main rail 3 and the right side of the right main rail 3 are provided with outer guide slots 32, and the right side of the left main rail 3 and the left side of the right main rail 3 are provided with inner guide slots 31.

[0072] In the outer cabinet body 5, a main lifting frame 1 and two upper and lower secondary lifting frames are installed, including an upper secondary lifting frame 2a located above and a lower secondary lifting frame 2b located below.

[0073] Referring to Figure 2 , the main lifting frame 1 includes left and right main lifting guides 11; the upper and lower ends of the right side of the left main lifting guide 11 are equipped with guide wheels 7, and the upper and lower ends of the left side of the right main lifting guide 11 are also equipped with guide wheels 7.

[0074] The main lifting guide 11 is provided with left and right main cantilevers 12 that protrude forward and left and right telescopic arms 14 that protrude forward; there is a middle rail 13 between the main cantilever 12 and the telescopic arm 14, and the main cantilever 12, the middle rail 13, and the telescopic arm 14 form a three-section rail pair.

[0075] A clothes rod 4 is installed between the left and right telescopic arms 14. Under the drive of the transmission mechanism hidden in the main cantilever cavity, the left and right telescopic arms 14 can respectively synchronously reciprocate within a range of 55 centimeters along the left and right main cantilevers 12.

[0076] Referring to Figure 3 , the composition of each secondary lifting frame 2 includes left and right secondary lifting guides 21; the upper and lower ends of the left side of the left secondary lifting guide 21 are equipped with guide wheels 7, and the upper and lower ends of the right side of the right secondary lifting guide 21 are also equipped with guide wheels 7.

[0077] Under the drive of the transmission mechanism, each sub-lifting guide 21 can move up and down along the inner guide groove 31 of the main rail 3 in synchronization; and the clothes hanging rod 4 is also installed between the left and right sub-lifting guides 21.

[0078] Referring to Figure 4 In use, when the user wants to use the clothes hanging rod 4 of the main lifting frame 1 currently located at the preset high position, the device can be started to first extend the telescopic arm 14 of the main lifting frame 1 by 55 centimeters. Then, under the drive of the steel wire hidden in the main rail 3, the two main lifting guides 11 of the main lifting frame 1 move along the outer guide groove 32 of the main rail 3 from the preset high position to the preset middle position, and simultaneously drive the telescopic arm 14 and the clothes hanging rod 4 that have been extended to the front to descend together.

[0079] Referring to Figure 5 When the telescopic arm 14 of the main lifting frame 1 is extended to the position and starts to descend together with the main lifting frame 1, the upper sub-lifting frame 2a can pass through the avoidance space between the main cantilever arms 12 of the main lifting frame 1 upwards to move to the preset high position located below the top of the outer cabinet body.

[0080] When the upper sub-lifting frame 2a is raised, the lower sub-lifting frame 2b controlled by the independent transmission mechanism can remain stationary at the preset low position, thereby leaving a preset middle position space for the main lifting frame 1.

[0081] Referring to Figure 6 , Figure 7 When the upper sub-lifting frame 2a is raised to the preset high position, and the main lifting frame 1 is lowered to the preset middle position between the upper sub-lifting frame 2a and the lower sub-lifting frame 2b, the telescopic arm 14 of the main lifting frame 1 and the clothes hanging rod therebetween can be retracted to the original position. At this time, the user can easily take and put clothes on the clothes hanging rod 4 directly lowered to the preset middle position.

[0082] Referring to Figure 8 , Figure 9 , Figure 10 When the user wants to lower the clothes hanging rod 4 on the main lifting frame 1 to the preset low position, or when the user wants to raise the clothes hanging rod 4 located at the preset low position to the preset middle position, the device can be started to first move the telescopic arm 14 of the main lifting frame 1 to the position, and then follow the main lifting frame 1 to the preset low position and to the original position, while raising the lower sub-lifting frame 2b to the preset middle position.

[0083] Obviously, when applied to a commercial display occasion, in order to display the front of the clothes, the left and right direction clothes hanging rod can be replaced by a front and back direction clothes hanging rod with multiple hooks.

[0084] According to the common clothes size, the distance between each clothes rod after returning to the original position can be set to about 80-90 cm. Therefore, for a bedroom or wardrobe with a headroom of about 2.7 m, the clothes storage space in one cabinet unit can be fully utilized, and each clothes rod can be moved to the height most suitable for users with normal height to take and put clothes. The problem of clothes not easy to take and put on high is solved.

[0085] According to the need, the machine box of the lifting transmission mechanism can be arranged at the top of the outer cabinet or at the bottom 54 of the outer cabinet. If arranged in the covered hidden space at the bottom 54 of the outer cabinet, it is most beneficial to save space and facilitate maintenance and repair of the mechanism.

[0086] Embodiment 2 is as shown in Figure 11 , Figure 12 .

[0087] The difference from embodiment 1 is that only one sub-lifting frame 2 is arranged in this embodiment, and the main lifting frame 1 and the sub-lifting frame 2 are arranged in the preset middle and high position areas. The lower space about 80 cm from the ground in the outer cabinet 5 is directly arranged with multiple shelves 55, which can be equipped with a door or a sliding door. Only the cabinet space with a headroom of about 1.8 m is used as the exchange operation space of the main lifting frame 1 and the sub-lifting frame 2. Obviously, in some cases, such a layout is more practical, not only can it still solve the problem of easy taking and putting clothes on high, but also can provide storage space for stacked clothes, and can also reduce the cost of the device.

[0088] Embodiment 3 is as shown in Figures 13 to 18 .

[0089] Referring to Figure 13 , Figure 14 , Figure 15 , this embodiment is based on embodiment 1, the clothes rod 4 on the main lifting frame 1 is replaced with a main storage cabinet 81, the clothes rod on the upper sub-lifting frame 2a is replaced with an upper sub-storage cabinet 81a, and the clothes rod on the lower sub-lifting frame 2b is replaced with a lower sub-storage cabinet 81b.

[0090] Referring to Figures 16 to 18 , the principle is the same as that of embodiment 1, and by means of the transmission mechanism, the main storage cabinet 81 at the preset high position can be exchanged with the upper sub-storage cabinet 82a at the middle position at any time according to the needs of the user; or the lower sub-storage cabinet 82b at the preset low position can be exchanged with the main storage cabinet 81. In this way, the user can always take and put the items in each storage cabinet within the height range most suitable for observation and operation.

[0091] In the same outer cabinet, clothes rods or storage cabinets can be installed on different lifting frames. For example, only clothes rods are installed on the main lifting frame 1, and storage cabinets are installed on the two sub-lifting frames 2.

[0092] Obviously, storage cabinets can be wooden cabinets made of planks, lightweight cabinets with soft grids made of cloth, or various types of storage cabinets such as sheet metal roll-up cabinets.

[0093] Example 4 Figures 19 to 23 As shown.

[0094] Based on embodiment 3, this embodiment has a forward-moving frame 6 at the front end of the outer cabinet 5.

[0095] See Figure 20 , Figure 21 The front-moving frame 6 is constructed including left and right front-moving frame side posts 61. The upper and lower ends of the front-moving frame side posts 61 are respectively provided with an upper insert arm 62 and a lower insert arm 63 that extend backward. With the help of a three-section guide rail that extends forward and backward, the upper insert arm 62 is inserted into and installed in the top 52 of the outer cabinet, and the lower insert arm is installed in the bottom 54 of the outer cabinet.

[0096] The inner side of the left and right forward-moving frame side posts 61 has vertical guide grooves. The front end of the telescopic arm 14 of the main lifting frame 1 and the bottom front side of the main storage cabinet side panel are provided with sliders that can slide along the inner guide grooves of the forward-moving frame side posts 61.

[0097] Under the action of the slider and guide groove, the forward moving frame 6 can move back and forth with the telescopic arm 14.

[0098] See Figures 21 to 23 Because the main locker 81 moves up and down between the forward-moving frame side post 61, which has already been moved to its position, and the outer cabinet 5, the forward-moving frame side post 61 gives the user a sense of visual security. Of course, in the event of a main locker falling off, the rigid structure of the forward-moving frame 6 can indeed play a certain role in mitigating the consequences of the accident.

[0099] See Figure 19 More importantly, the repositioned sliding frame can conceal the gaps reserved by the mechanism on both sides of each storage cabinet, contributing to a better product appearance. The decorative coating on the outer surface of the sliding frame side post 61 will further enhance the aesthetics.

[0100] Example 5 Figure 24 As shown. This embodiment is a wardrobe design specifically designed according to the basic principles of the present invention. The telescopic arm 14 of the main lifting frame 1 is combined with the movable rail of a heavy-duty three-section guide rail, and the fixed rail of the three-section guide rail is combined with the main cantilever 12. In order to provide more space for the drive mechanism of the telescopic arm 14, a transmission mechanism housing 9 is also provided between the telescopic arms 14 of the main lifting frame 1.

[0101] A shelf 55 is arranged in the outer cabinet 5 at a distance of 95 cm from the floor. A clothes rail 4 is mounted below this shelf 55. In this way, a wardrobe product is formed with two liftable clothes rails and one fixed clothes rail.
