Storage device with lifting mechanism

Abstract

A storage device with a lifting mechanism comprises a main lifting frame 1 and at least two auxiliary lifting frames 2 which are installed between a left main guide rail 3 and a right main guide rail 3. Telescopic arms 14 capable of stretching forwards from the main cantilever 12 are arranged on the two sides of the main lifting frame 1, and certain object carrying components such as a clothes rail and a storage cabinet are arranged between the telescopic arms 14; after the telescopic arm 14 extends forwards in place, the main lifting frame 1 and the auxiliary lifting frame 2 can perform reverse lifting action and exchange positions, so that the object carrying component at an over-high position or an over-low position can descend or ascend to a height position most suitable for a user to take objects, and the living pain point that the objects placed in the high-rise storage cabinet are not easy to take, place and tidy is solved.

Description

Technical Field

[0001] The invention relates to a storage device, and in particular to a storage device with a lifting mechanism. Background Art

[0002] Due to the limitation of human height, storage spaces that are too high, such as items in cabinet shelves in a closet that are more than 1.9 meters above the ground, are not convenient for people standing on the ground to take and organize. In commercial settings, although the height of the venue is high enough to place very tall storage cabinets, although the goods placed at a higher position can be displayed, it is not convenient for store clerks and customers to observe and take them up close. The problem is particularly obvious for goods such as clothing, shoes and hats displayed at high positions. In addition to items placed at high positions, items placed in very low spaces near the ground also require people to squat when observing and taking them, and the storage and retrieval operations are not convenient enough. When the items in the storage compartment are only 20 centimeters above the ground, it is even more difficult to bend over and check.

[0003] In response to the above pain points, the auxiliary devices that already exist on the market can be roughly divided into two categories: one is a locker or storage compartment that can be raised and lowered forward and downward through a telescopic mechanism, and the other is a manual or electric clothes hanging device that can be folded forward and downward. However, these two types of devices still have the following problems:

[0004] 1. Every time a user needs to take or put items in a lowerable locker or take or hang clothes on a foldable clothes hanger, the device must perform a forward and return action, which is time-consuming and troublesome.

[0005] 2. In these two solutions, the height of the high storage space or clothes hanger from the ground is limited, and the near-top space of the ceiling-to-ceiling locker cannot be fully utilized. Storage compartments near the top space with a height of more than 2.1 meters from the ground still cannot be covered by the device.

[0006] 3. If you use folding clothes hangers to store out-of-season clothes, when the season changes, you need to replace the out-of-season clothes with new clothes on the lower hangers, which increases the operation process and is not convenient enough.

[0007] 4. Due to the limited application height, it is difficult to use it for multi-layer commodity display and storage in high wall cabinets in commercial exhibition halls.

[0008] 5. It cannot be applied to near-ground storage spaces, and thus cannot solve the inconvenience of squatting required in near-ground storage spaces. Summary of the invention

[0009] In order to solve the above-mentioned defects of the prior art, the present invention proposes a storage device with a lifting mechanism, which is characterized by:

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

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

[0012] The main lifting guide part 11 is provided with left and right main cantilevers 12 and left and right telescopic arms 14 extending forward; a carrying component is installed between the left and right telescopic arms 14; driven by the transmission mechanism, the left and right telescopic arms 14 can be synchronously extended and retracted along the left and right main cantilevers 12 respectively;

[0013] The auxiliary lifting frame 2 includes left and right auxiliary lifting guide parts 21. Under the drive of the transmission mechanism, each auxiliary lifting guide part 21 can be synchronously lifted and lowered along the inner guide groove 31 of the main rail 3; a loading component is installed between the left and right auxiliary lifting guide parts 21;

[0014] When the telescopic arm 14 of the main lifting frame 1 is extended forward to a preset length, each main lifting guide part 11 can be lifted and moved along the outer guide groove 32 of the main rail 3 between a preset high position and a preset low position under the drive of the transmission mechanism. At the same time, the telescopic arm 14 and the object-carrying component of the main lifting frame 1 can be lifted and moved along the main lifting frame 1 between a preset high position and a preset low position in front of the auxiliary lifting frame 2;

[0015] When the telescopic arm 14 of the main lifting frame 1 is extended forward by a preset length, the auxiliary lifting frame 2 can move up and down in the space between the main cantilevers 12 of the main lifting frame 1;

[0016] When the auxiliary lifting frame 2 is raised to a preset high position and the main lifting frame 1 is lowered to a preset low position in front of and below the auxiliary lifting frame 2, the telescopic arm 14 of the main lifting frame 1 and the cargo-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 raised to a preset high position above and in front of the auxiliary lifting frame 2 , the telescopic arms 14 of the main lifting frame 1 and the object-carrying components 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 includes an upper auxiliary lifting frame 2a and a lower auxiliary lifting frame 2b located below the upper auxiliary lifting frame 2a.

[0021] 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 raised to the preset high position; the telescopic arm 14 of the main lifting frame 1 lowered to the preset middle position and the cargo 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 located at the preset high position is extended forward by a preset length, the upper auxiliary lifting frame 2a located at the preset middle position can be raised to the preset high position, and the lower auxiliary lifting frame 2b located at the preset low position can be raised to the preset middle position; the telescopic arm 14 of the main lifting frame 1 lowered to the preset low position and the cargo carrying parts therebetween can be retracted to below the lower auxiliary lifting frame 2b.

[0023] Obviously, the object carrying component may be a clothes hanger 4 or a storage cabinet 8 .

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

[0025] Relying on the above-mentioned technical features, when two auxiliary lifting frames 2 are used, even the storage space at a preset low position can be raised to a preset middle position, and the storage space that is too low can also be raised to the preset middle position, thereby solving the problem that items in the low space are difficult to observe and access, and further achieving the purpose of the invention.

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

[0027] The device also includes a fixed outer cabinet 5,

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

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

[0030] A forward frame 6 is provided at the front end of the outer cabinet 5; the forward frame 6 includes forward frame side columns 61 on the left and right sides; upper and lower ends of the forward frame side columns 61 are respectively provided with an upper insert arm 62 and a lower insert arm 63 that cantilever backward; the upper insert arm 62 is inserted into the top 52 of the outer cabinet by means of a front and rear telescopic guide member, and the lower insert arm is inserted into the bottom 54 of the outer cabinet by means of a front and rear telescopic guide member;

[0031] The left and right forward moving frame side columns 61 are slidably connected to the front end of the telescopic arm 14 of the main lifting frame 1 through a vertical guiding structure, and can move forward and backward with the telescopic arm 14 .

[0032] The forward frame 6 is provided to solve the problem of the gap between the two sides of the lockers 81 and 82 on each layer and the side panels 51 of the outer cabinet, thus improving the overall appearance of the product. In addition, the forward frame side column 61, which can follow and assist in guiding the telescopic arm 14 of the main lifting frame 1 to move forward and backward and lift, also improves the more reliable guiding and limiting function of the main lifting component and further prevents the main locker from tilting forward and falling during lifting. At the same time, in terms of appearance, it also increases the user's visual sense of product safety.

[0033] In this article, the term "transmission mechanism" includes a drive system that uses a motor, electric push rod, manual crank or manual push-pull component as a power source through a transmission component such as a wire rope, chain or synchronous belt;

[0034] The term "front" means that when observing the components shown in the referenced view, the direction pointing to the observer is called "front", and the direction away from the observer is called "rear"; the terms "up", "down", "left" and "right" are based on the up, down, left and right of the referenced view. The term "bottom" refers to the lower end of a specific component in the referenced view in the drawing, and "top" refers to the upper end of a specific component in the referenced view in the drawing.

[0035] The above orientation terms are only intended to facilitate accurate description of the relative positional relationship of the various parts of the present invention, rather than indicating or implying that the referred parts must have a specific orientation, or must be combined and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] The terms "preset high position", "preset middle position" and "preset low position" are height positions or height limit ranges that are preset during product design based on the needs of different space applications and the needs of product space height limitations.

[0037] The term "preset length" refers to the maximum telescopic amount that needs to be set according to the pre-designed telescopic arm of the main lifting frame to avoid conflict with the auxiliary lifting frame.

[0038] The term "vertical guiding structure" refers to a sliding pair that matches a guiding groove or ridge located on the side of the forward moving frame side column 61 and is installed on the side of the telescopic arm 14 or the main storage cabinet 81. The sliding pair should ensure that the forward moving frame side column 61 can move forward and backward with the main storage cabinet 81.

[0039] The term "front-rear telescopic guide member" refers to a telescopic guide member that can guide the front frame side column 61 to move only back and forth, such as a three-section guide rail, or a plug-in pair consisting of a rod and a cylinder.

[0040] More specific technical features and beneficial effects of the present invention will be further described in detail in the following embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0071] See also Figure 1 This embodiment is a wardrobe application solution with three clothes hanging rods 4 designed according to the principle of the present invention. It adopts an outer cabinet 5 with a height of 2.8 meters. The back panel inside the outer cabinet 5 is equipped with two left and right main rails 3, wherein the left side of the left main rail 3 and the right side of the right main rail 3 are provided with outer guide grooves 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 grooves 31.

[0072] A main lifting frame 1 and two upper and lower auxiliary lifting frames are installed in the outer cabinet 5, including an upper auxiliary lifting frame 2a located at the top and a lower auxiliary lifting frame 2b located at the bottom.

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

[0074] The main lifting guide part 11 is provided with left and right main cantilevers 12 cantilevered forward and left and right telescopic arms 14 cantilevered 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 constitute a three-section track pair.

[0075] A clothes hanging rod 4 is provided between the left and right telescopic arms 14. Driven by a transmission mechanism hidden in the main cantilever structure cavity, the left and right telescopic arms 14 can be reciprocated synchronously within a range of 55 cm along the left and right main cantilevers 12, respectively.

[0076] See also Figure 3 Each auxiliary lifting frame 2 includes left and right auxiliary lifting guide parts 21. The upper and lower ends of the left side of the auxiliary lifting guide part 21 on the left are equipped with guide wheels 7, and the upper and lower ends of the right side of the auxiliary lifting guide part 21 on the right are also equipped with guide wheels 7.

[0077] Driven by the transmission mechanism, each auxiliary lifting guide part 21 can be lifted and moved synchronously along the inner guide groove 31 of the main rail 3; a clothes hanging rod 4 is also installed between the left and right auxiliary lifting guide parts 21.

[0078] See also 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 activated to first extend the telescopic arm 14 of the main lifting frame 1 forward by 55 cm. Then, driven by the steel wire rope hidden in the main guide rail 3, the two main lifting guide parts 11 of the main lifting frame 1 move from the preset high position to the preset middle position along the outer guide groove 32 of the main guide rail 3, and at the same time drive the telescopic arm 14 and the clothes hanging rod 4 that have been extended to the front to descend together.

[0079] See also Figure 5 When the telescopic arm 14 of the main lifting frame 1 is extended forward to the position and starts to descend together with the main lifting frame 1, the upper auxiliary lifting frame 2a can pass upward through the avoidance space between the main cantilevers 12 of the main lifting frame 1 and move to the preset high position below the top of the outer cabinet.

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

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

[0082] See also Figure 8 , Fig. 9 , Fig.10 When the user wants to lower the clothes hanging rod 4 on the main lifting frame 1 to a preset low position, or when the user wants to raise the clothes hanging rod 4 at the preset low position to a preset middle position, the device can be started to first move the telescopic arm 14 of the main lifting frame 1 forward to a position, and then follow the main lifting frame 1 to lower to the preset low position and return to its position, and at the same time, the lower auxiliary lifting frame 2b is raised to the preset middle position.

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

[0084] According to common clothing sizes, the distance between the clothes hangers after they are put back in place can be set to about 80-90 cm. Therefore, for a bedroom or cloakroom with a clearance height of about 2.7 meters, the clothing storage space in a cabinet unit can be fully utilized, and each clothes hanger can be moved to the most suitable height for users of normal height to take and put. This solves the problem of clothes hanging at high places being difficult to take and put.

[0085] As required, the chassis of the lifting transmission mechanism can be arranged on the top of the outer cabinet, and can also be arranged on the outer cabinet bottom 54. If it is arranged in the hidden space with cover at the outer cabinet bottom 54, it will be most conducive to saving space and be convenient to the maintenance and repair of the mechanism.

[0086] Example 2 Fig.11 , Fig.12 shown.

[0087] The difference from Example 1 is that in this embodiment, only one auxiliary lifting frame 2 is provided, and both the main lifting frame 1 and the auxiliary lifting frame 2 are arranged in the preset middle position and the preset high position area. The lower space of the outer cabinet 5, about 80 cm above the ground, is directly provided with a multi-layer shelf 55, and an opening door or a sliding door can be installed. Only the space in the cabinet with a clearance height of about 1.8 meters above is used as the exchange operation space of the main lifting frame 1 and the auxiliary lifting frame 2. Obviously, in some occasions, such a layout is more practical, not only can it still solve the problem of easy access to clothes at high places, but also can provide storage space for stacked clothes, and can also reduce the cost of the device.

[0088] Example 3 Figures 13 to 18 shown.

[0089] See also Fig.13 , Fig.14 , Fig.15 In this embodiment, on the basis of the embodiment 1, the clothes hanging rod 4 on the main lifting frame 1 is replaced with a main storage cabinet 81, the clothes hanging rod on the upper auxiliary lifting frame 2a is replaced with an upper auxiliary storage cabinet 81a, and the clothes hanging rod on the lower auxiliary lifting frame 2b is replaced with a lower auxiliary storage cabinet 81b.

[0090] See also Figures 16 to 18 , the principle is the same as that of the first embodiment. With the help of the transmission mechanism, according to the needs of the user, the main locker 81 at the preset high position can be swapped with the upper auxiliary locker 82a at the middle position at any time; or the lower auxiliary locker 82b at the preset low position can be swapped with the main locker 81. In this way, the user can always take and place the items in each locker within the height range that is most suitable for observation and taking and placing operations.

[0091] In the same outer cabinet, clothes hanging rods or lockers can be installed on different lifting racks. For example, only clothes hanging rods are installed on the main lifting rack 1, and lockers are installed on the two auxiliary lifting racks 2.

[0092] Obviously, the storage cabinet can be a wooden cabinet made of wooden boards, a soft grid lightweight cabinet made of cloth, or a metal roll cabinet and other types of storage cabinets.

[0093] Example 4 Figures 19 to 23 shown.

[0094] Based on the third embodiment, a forward frame 6 is provided at the front end of the outer cabinet 5 in this embodiment.

[0095] See also Fig. 20 , Fig.21 The structure of the forward frame 6 includes forward frame side columns 61 on the left and right sides. The upper and lower ends of the forward frame side columns 61 are respectively provided with an upper insert arm 62 and a lower insert arm 63 that are cantilevered backward. With the help of a three-section guide rail that telescopes forward and backward, the upper insert arm 62 is inserted 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] There are vertical guide grooves on the inside of the left and right forward moving frame side pillars 61. The front end of the telescopic arm 14 of the main lifting frame 1 and the front bottom of the main storage cabinet side plate are provided with a slide block that can slide along the inner guide groove of the forward moving frame side pillars 61.

[0097] Under the action of the above-mentioned slider and guide groove, the forward frame 6 can move forward and backward following the telescopic arm 14.

[0098] See also Figure 21 to Figure 23 Since the main locker 81 moves up and down between the forward frame side pillars 61 and the outer cabinet 5, the forward frame side pillars 61 give the user a visual sense of security. Of course, in the event of the main locker falling off, the rigid forward frame 6 can indeed play a certain security role in alleviating the consequences of the accident.

[0099] See also Fig.19 More importantly, the front moving frame after returning to its original position can cover the reserved gaps of the mechanisms on both sides of each locker, which is conducive to forming a good product appearance. The decorative coating on the outer surface of the front moving frame side column 61 will further beautify the shape.

[0100] Example 5 Fig.24 As shown. This embodiment is a design scheme of a wardrobe specifically designed according to the basic principle of the present invention. The telescopic arm 14 of the main lifting frame 1 is combined with a movable rail of a heavy three-section guide rail, and the fixed rail of the three-section guide rail is combined with the main cantilever 12. In order to arrange a more spacious space for the driving mechanism of the telescopic arm 14, a transmission mechanism chassis 9 is also set between the telescopic arms 14 of the main lifting frame 1.

[0101] A shelf 55 is arranged at 95 centimetres from the bottom plate below the outer cabinet 5. A clothes hanging rod 4 is installed below this shelf 55. Like this, a wardrobe product with two liftable clothes hanging rods and a fixed clothes hanging rod is formed.
