Description

Technology Field

[0001] The present invention relates to a height adjustment device for storage furniture, and more specifically, to a technology that enables the height of the front and rear lower sections of the main body to be easily adjusted from inside the storage furniture when installing storage furniture for storing or organizing items, thereby allowing the main body of the storage furniture to be leveled easily and the installed state to be maintained more stably. Background Technology

[0002] Generally, storage furniture is a doored unit designed to store or organize documents, items, tools, etc., such as cabinets, lockers, bookshelves, lockers, wardrobes, filing cabinets, storage boxes, and drawers. It is formed from various materials such as metal and plastic and is equipped with shelves or drawers inside, so it is used in various places such as offices, kitchens, and warehouses.

[0003] The structure of such storage furniture basically consists of a main body made up of a top panel, side panels, bottom panel, and back panel, and doors. Most storage furniture features adjustable or fixed internal shelves or drawers to organize items. The doors are connected to the main body via hinges to allow them to be opened and closed.

[0004] Storage furniture comes in various forms depending on the installation method and purpose of use; freestanding units, which are typically placed directly on the floor, are utilized in diverse spaces due to their ease of movement and installation. To install storage furniture, select a location that does not obstruct electrical outlets or passageways, check the space dimensions considering the operating range to ensure unimpeded door opening and closing, assemble the main unit on the floor, and then position it in an appropriate location.

[0005] As an example of the disclosed technology, Korean Registered Utility Model No. 20-0386296 describes a cabinet formed in the shape of a rectangular prism, having at least one shelf inside to store books, and equipped with a top plate and a bottom plate, side plates installed on both sides of the top plate and the bottom plate, a back plate installed at the rear of the top plate and the bottom plate, and a door installed at the front of the top plate and the bottom plate that opens and closes.

[0006] As another example, Korean Registered Patent No. 10-1053993 comprises a multi-purpose cabinet having a pair of side plates spaced apart in parallel with each other, a partition plate positioned between the side plates parallel to the side plates to divide the space between the side plates into multiple storage compartments, a main body having multiple upper and lower plates with both ends connected to adjacent surfaces of the side plates and the partition plate to support the side plates and the partition plate, multiple back plates connected to the rear of the main body to close the back of the storage compartments divided by the side plates, and multiple doors hinged to the side plates and the partition plate to open and close the front of the storage compartments.

[0007] Meanwhile, the bottom surface of the storage furniture body is provided with legs to support the body while being spaced apart from the floor surface. The legs of the storage furniture generally come in the form of a horizontal support attached integrally to the bottom surface, a caster type with wheels, or a leveler type in which a screw is provided on a disc-shaped support to be fastened to the bottom surface of the body.

[0008] For example, Korean Registered Patent No. 10-0068970 comprises a cabinet having a device body that allows for free withdrawal and storage of the cabinet, a first caster installed on the rear lower surface of the cabinet, a second caster installed on the front lower surface of the device body, and a leg member installed on the front lower surface of the cabinet. Prior art literature

[0009] Korean Utility Model No. 20-0386296 (June 10, 2005) Korean Patent No. 10-1053993 (August 4, 2011) Korean Patent No. 10-0068970 (September 11, 1993) Korean Utility Model No. 20-0251920 (November 17, 2001) The problem to be solved

[0010] Since storage furniture is used to store items on internal shelves or in drawers, maintaining a level surface is crucial during installation. If the surface is not level, problems such as doors opening or closing by themselves may occur, and in the long run, it can also affect durability.

[0011] Therefore, after installing storage furniture, it must be checked whether the floor and the top of the storage furniture are level. If the furniture is not level, storage furniture equipped with legs in the form of supports or casters to which conventional technology is applied must have a specific board added to the bottom of the legs and leveled by tightening or loosening the leveler.

[0012] However, in conventional storage furniture, for example, when other furniture or walls are placed in close proximity to the storage furniture or when multiple storage furniture units are arranged horizontally without spacing, it is impossible to support a board on the leg located at the back of the main body or to operate a leveler. Consequently, there is the inconvenience of having to temporarily move the surrounding furniture, level it, and return it to its original position, and there are problems such as difficulty in aligning the heights of multiple storage furniture units evenly during this process. means of solving the problem

[0013] Accordingly, the present invention was developed to solve the problems of the prior art as described above, and

[0014] A keeper (100) mounted on the lower plate (1) of the storage furniture to maintain the entire control device, and

[0015] An inner operating member (200) mounted on the lower side of the keeper (100) and raised or lowered relative to the outer operating member (300) by rotational operation, and

[0016] It includes an outer operating member (300) that is coupled to the outer side of the inner operating member (200) and operates to rise or fall relative to the inner operating member (200) by rotational operation, and

[0017] The above inner operating member (200) is provided to adjust the height by rotating it on the upper side of the lower plate (1) inside the storage furniture using a tool, and

[0018] The above-mentioned external operating mechanism (300) is configured so that the user can adjust the height by rotating it with their hand in front of the lower plate (1) outside the storage furniture, thereby enabling the purpose of easily adjusting the height of the front and rear lower parts of the main body from inside the storage furniture when the storage furniture is installed. Effects of the invention

[0019] The present invention provides an adjustment device that allows the height of the front and rear lower sections of the main body to be easily adjusted from inside the storage furniture when the storage furniture is installed.

[0020] Therefore, the present invention has the advantage of easily leveling the main body of the storage furniture and maintaining a more stable installation state, thereby resolving problems that occur when the furniture is not level, such as the door not operating properly, the main body shaking, or the storage furniture tipping over.

[0021] In particular, the present invention allows the rear height of the main body to be easily adjusted using a tool inside the storage furniture even when other furniture or walls are placed in close contact with the storage furniture or when multiple storage furnitures are arranged horizontally without gaps. Therefore, unlike conventional technology, there is no inconvenience of having to temporarily move surrounding furniture, level it, and return it to its original position, and the height of multiple storage furnitures can be aligned evenly while maintaining a horizontal state, thereby significantly improving convenience of use and safety.

[0046] The adjustment screw portion (220) is formed on the outer surface of the inner operating body (210) at the lower side of the locking portion (212) and is provided to be screw-coupled with the outer operating body (310).

[0047] Meanwhile, between the first plate (110) or second plate (120) of the keeper (100) and the inner operating member (200), a friction reduction means (410) is provided to increase rotational operability while separating the contact surfaces from each other.

[0048] The friction reduction means (410) is composed of a ring-shaped protrusion or a ball-shaped protrusion. For example, the ring-shaped friction reduction means (410) is formed integrally on the bottom surface of the first plate (110) or the second plate (120) or on the upper surface of the inner operating body (210) to reduce the frictional force at the contact area by the curved ring shape of the protrusion. For example, the ball-shaped friction reduction means (410) is configured such that a predetermined spherical groove is formed on the upper surface of the inner operating body (210) to accommodate a ball, with a portion of the upper part protruding so that the bottom surface of the first plate (110) or the second plate (120) makes rolling contact with the upper part of the ball to reduce the frictional force.

[0049] The outer operating member (300) is coupled to the outer side of the inner operating member (200) and is configured to move up or down relative to the inner operating member (200) by rotational operation.

[0050] The outer operating member (300) is provided to allow a user to adjust the height by rotating it with their hand in front of the lower plate (1) outside the storage furniture, and includes an outer operating body (310), a hoof (320), and a friction increasing means (330).

[0051] The outer operating body (310) is formed as a cylindrical shape having a hollow portion and is provided with an adjusting female screw portion (311) on its inner surface to be screw-coupled with the adjusting male screw portion (220) of the inner operating member (200).

[0052] The hoof (320) is formed at the bottom of the outer operating body (310) to contact the floor surface and is provided to support the storage furniture.

[0053] A friction-increasing means (330) is formed on the outer surface of the outer operating body (310) to increase the gripping force when the user rotates it by hand.

[0054] Below, we examine the general usage state of a storage furniture height adjustment device to which the technology of the present invention is applied, which is configured as described above.

[0055] For example, when multiple storage furniture units are arranged in a row in the horizontal direction or when walls are blocked on both sides of the storage furniture, it is impossible to adjust the legs located at the rear of the storage furniture using conventional methods of adjusting levelers or supporting panels.

[0056] In the storage furniture height adjustment device according to the present invention, a keeper (100) is mounted on a lower plate (1), and an inner operating member (200) and an outer operating member (300) are mounted on the lower side of the keeper (100). When the door of the storage furniture is opened, a tool coupling part (211) is exposed through mounting holes formed at four locations on the upper surface of the lower plate (1), including the front, back, left, and right sides.

[0057] FIG. 8 illustrates the operating state of a storage furniture height adjustment device according to a second embodiment of the present invention. A user rotates the inner operating member (200) in one direction by connecting it to the tool coupling part (211) using an adjustment tool, such as a hex wrench. The inner operating member (200) rotates while reducing the frictional force of the contact part by means of a friction reduction means (410), with the upper part of the inner operating body (210) of the inner operating member (200) being received in the lower second operating space part (122) of the second plate (120) of the keeper (100), where the second flange (123) is fixed to the lower plate (1) of the storage furniture. The inner operating body (210) rotates while maintaining the axial direction during rotation by means of the second vertical rim (121) of the keeper (100).

[0058] When the inner operating member (200) is rotated, the outer operating member (300) is supported on the floor surface by the weight of the storage furniture and remains in a stationary state, so the male adjustment screw part (220) of the inner operating member (200) moves upward along the female adjustment screw part (311) of the outer operating member (300) to raise the height of the storage furniture. In addition, when the inner operating member (200) is rotated in the opposite direction, the height of the storage furniture is lowered in the reverse order of the above. The operating mechanism of the first embodiment is also the same.

[0059] The present invention may also adjust the height by grasping the friction-increasing means (330) of the outer operating body (310) of the outer operating member (300) by hand from the outside of the storage furniture and rotating it in one direction.

[0060] The storage furniture height adjustment device according to the present invention, as described above, has the advantage of being able to easily adjust the height of the rear of the main body using a tool inside the storage furniture, by configuring an adjustment device that can easily adjust the height of the front and rear lower parts of the main body when installing the storage furniture, for example, even when other furniture or a wall is placed in close contact with the storage furniture or when multiple storage furnitures are arranged horizontally without gaps.

[0061] Therefore, the present invention has the effect of significantly improving user convenience and safety, such as eliminating the inconvenience of having to temporarily move surrounding furniture to level and return it to its original position to adjust the rear height of the main body as in conventional technology, and enabling the leveling of multiple storage furniture units while maintaining a level state.
