Description

Technology Field

[0001] The present invention relates to a height-adjustable glide that is installed on the bottom of furniture and can adjust its height. Background Technology

[0003] Although building or indoor floors are generally constructed to be flat, it is common to see defective floors where the entire surface is not flat and parts of the floor protrude or are sunken.

[0004] Therefore, when installing the product on an uneven floor surface, it was difficult to ensure that the product was balanced or leveled during installation.

[0005] Conventional height-adjustable supports are described in detail in Registered Patent No. 10-0586895 "Furniture Leg Support" and Published Patent No. 10-2007-0077577 (July 27, 2007) "Multipurpose Support".

[0006] Conventional supports are characterized by using screws to adjust the height of the support so that the product can be leveled. However, if the floor where the product is installed is sloped, the support cannot be stably supported on the floor surface, which can cause the product to wobble or become unstable during use.

[0007] In addition, as can be seen in the table or chair among the aforementioned products, in the case of products with inclined legs, the aforementioned support member is used at the bottom of the inclined leg, but because the contact surface of the support member attached to the inclined leg is not evenly contacted with the floor surface due to the angle of connection, it is difficult to stably support horizontality or balance, and there was a problem that the product became unstable, such as wobbling when in use.

[0059] The guide column (242) is screw-coupled with the nut (150).

[0060] The upper end of the guide column (242) is inserted into the fixed glide space (101) by penetrating the fixed guide groove (121) and the fixed guide hole (122).

[0061] The upper end of the above guide column (242) is positioned within the height of the assembly body (220).

[0062] The assembly body (220) includes an assembly housing portion (225) that extends upward from the movable body (210), and an assembly locking portion (230) that protrudes radially outward from the top of the assembly housing portion (225) and forms a mutual locking with the lock (300) in the up and down direction.

[0063] In this embodiment, the arm (250) is placed in the assembly housing (225).

[0064] The assembly housing portion (225) is formed in a cylindrical shape. The assembly housing portion (225) extends upward from the top of the movable housing portion (211).

[0065] The inner diameters of the assembly housing part (225) and the movable housing part (211) are the same, forming a continuous inner surface. The outer surface of the assembly housing part (225) is formed to be smaller than the outer surface of the movable housing part (211).

The outer diameter of the assembly catch portion (230) is formed to be smaller than the outer diameter of the movable housing portion (211).

[0068] The assembly catch portion (230) can be formed in a truncated cone shape.

[0069] The assembly catch portion (230) includes an assembly inclined surface (233) arranged to be inclined downward in a radial direction outward, and an assembly catch portion (232) bent in a radial direction inward at the bottom of the assembly inclined surface (233).

[0070] It further includes an assembly slit (235) that penetrates the assembly catch (230) in the vertical direction and forms a continuous surface with the outer surface of the assembly body (220).

[0071] The lower end of the lock (300) can be positioned to pass through the assembly catch (230) via the assembly slit (235) and surround the assembly body (220).

[0075] The above-mentioned cut groove (222) includes an upper cut groove (222a) that penetrates the assembly housing portion (225) in a radial direction and is formed long in the circumferential direction of the assembly housing portion (225), a lower cut groove (222b) that penetrates the assembly housing portion (225) in a radial direction and is formed long in the circumferential direction of the assembly housing portion (225) and is arranged parallel to the lower side of the upper cut groove (222a), and a connecting cut groove (222c) that connects one end of the upper cut groove (222a) and the lower cut groove (222b).

[0076] The above connecting cut groove (222c) and assembly slit (235) are characterized by being arranged in a line in the vertical direction.

[0077] The arm (250) is formed between the upper cut groove (222a), the lower cut groove (222b), and the connecting cut groove (222c). One end of the arm (250) is positioned toward the connecting cut groove (222c), and the other end is formed integrally with the assembly housing part (225).

[0078] Unlike the present embodiment, it is acceptable to form an assembly opening that penetrates the assembly housing part (225) in the radial direction and to manufacture and assemble the arm.

[0079] The above arm (250) is formed such that its thickness increases from one end to the other.

[0080] The above arms (250) may be arranged in multiple numbers, and in this embodiment, include a first arm (250a), a second arm (250b), and a third arm (250c).

[0081] When viewed from the top, the first arm (250a), the second arm (250b), and the third arm (250c) are arranged at equal intervals of 120 degrees.

[0082] The above lock (300) includes a lock body (310) formed in a ring shape and a lock engaging part (320) that protrudes radially inward from the inner circumference of the lock body (310) and interferes with the arm (250) when rotated to deform the arm (250) radially inward.

[0083] The above-mentioned lock body (310) is formed in a ring shape and is arranged to surround the outer surface of the above-mentioned assembly body (220).

[0084] It further includes a locking member (312) that is formed concavely from the top to the bottom of the lock body (310) to form a locking groove (313).

[0085] When assembling the lock body (310) and the assembly body (220), the assembly catch portion (232) is positioned above the lock catch portion (312), and the assembly catch portion (232) and the lock catch portion (312) form mutual locking in the vertical direction, and the lock (300) has the feature of preventing the assembly body (220) from being separated.

[0086] The above locking groove (313) is formed concavely outwardly in the radial direction from the inner circumference of the lock body (310) and is positioned at the top in this embodiment. The locking end (312) is positioned at the bottom of the locking groove (313).

[0087] The above locking portion (320) may be arranged in multiple numbers. In this embodiment, the locking portion (320) corresponds to the number of arms (250). In this embodiment, the locking portion (320) includes a first locking portion (320a), a second locking portion (320b), and a third locking portion (320c), and when viewed from the top view, they are arranged at equal angles at 120-degree intervals.

[0088] The structure of the first locking part (320a), the second locking part (320b), and the third locking part (320c) is identical. The first locking part (320a), the second locking part (320b), and the third locking part (320c) protrude toward the axis center.

[0089] The configuration of the first locking part (320a), the second locking part (320b), and the third locking part (320c) is described by collectively referring to the locking part (320).

[0090] The above locking portion (320) includes a locking body portion (321) that protrudes radially inward from the inner circumferential surface (311) of the locking body (310), and a lock support that protrudes further radially inward from the locking body portion (321).

[0091] The above locking body part (321) is formed by extending long in the vertical direction.

[0092] The above locking body part (321) is formed in the shape of a part of a cylinder and is formed in a convex shape radially inward.

[0093] The above lock support includes a lower lock support (322) that protrudes radially inward from the bottom of the locking body part (321). Unlike the present embodiment, the lock support may further include an upper lock support (not shown) that protrudes radially inward from the top of the locking body part (321).

[0094] It is acceptable to place either the lower lock support (322) or the upper lock support.

[0095] The lower lock support (322) and upper lock support are formed in the shape of a semicircular plate and are formed convexly inward in the radial direction, and form mutual locking with the assembly body (220) in the vertical direction.

[0096] The lower lock support (322) and upper lock support can pass through the assembly slit (235) and enter the cut groove (222).

[0097] The width of the lower lock support (322) and the upper lock support is formed to be smaller than the width of the assembly slit (235).

[0098] The thickness of the lower lock support (322) and the upper lock support is formed to be smaller than the thickness of the upper cut groove (222a) and the lower cut groove (222b).

[0099] After the lower lock support (322) and upper lock support are inserted into the connecting cut groove (222c) through the assembly slit (235), they are slid along the lower cut groove (222b) and upper cut groove (222a).

[0100] The lower lock support (322) is inserted into the lower cut groove (222b) and slides in the circumferential direction of the assembly body (220), and the upper lock support is inserted into the upper cut groove (222a) and slides in the circumferential direction of the assembly body (220).

[0101] The lower lock support (322) and upper lock support are inserted into the cut groove (222) and form mutual locking in the upper and lower directions.

[0102] In this embodiment, the lower lock support (322) passes through the cut groove (222) and protrudes into the assembly body (220), and is characterized by forming a mutual lock with the fixing locking part (125) of the fixing glide (100) in the up and down direction.

[0103] The lower lock support (322) is positioned on the upper side of the fixed catch portion (125), and the lower lock support (322) is caught on the fixed catch portion (125) to prevent separation of the fixed glide (100) and the movable glide (200).

[0104] When the lock (300) rotates horizontally, the lock engaging part (320) interferes with the arm (250) and pushes the arm (250) radially inward to elastically deform it, and through this, the arm (250) comes into close contact with the fixed glide (100) to fix the movable glide (200) and the fixed glide (100).

[0105] The above arm (250) includes an arm body (251) that extends in the circumferential direction of the assembly body (220) in the assembly housing part (225), and an arm locking groove (253) that is formed concavely inwardly in the radial direction from the outer surface of the arm body (251) and into which the locking part (320) is inserted to form mutual interference in the circumferential direction.

[0106] The above-mentioned arm body (251) is formed such that its thickness increases from one end to the other end. That is, the side connected to the assembly housing (225) (the other end) is thick, and the side of the connecting cut groove (222c) is formed to be thin.

[0107] When the lock (300) is rotated in the other direction, the locking body part (321) pushes the arm body (251) radially inward to elastically deform it, and when the lock (300) is rotated in one direction, the elastic deformation of the arm body (251) is restored to its original state.

[0108] When the above arm body (251) is inserted into the above arm locking groove (253), a “click” sound is produced, allowing the user to intuitively recognize the locked state of the lock (300).

[0109] The connection portion of the above-mentioned arm body (251) and assembly housing portion (225) is formed thinly for elastic deformation. To this end, the arm (250) further includes an arm body deformation groove (254) formed concavely inwardly in the radial direction from the outer surface of the other end of the arm body (251).

[0110] The above-mentioned arm body deformation groove (254) is formed long in the vertical direction.

[0111] The above arm body deformation groove (254) is formed deeper than the above arm catch groove (253).

[0112] In this embodiment, the area between the arm body deformation groove (254) and the arm locking groove (253) in the arm body (251) is called the arm body neck portion (252). The thickness of the arm body neck portion (252) prevents the locking body portion (321) from entering the arm body neck portion (252).

[0113] That is, by forming a narrow gap between the inner surface (311) of the arm body neck portion (252) and the lock body (310), the locking body portion (321) can be prevented from moving from the arm locking groove (253) to the arm body deformation groove (254), and thereby, the reliability of operation can be improved.

[0114] The height-adjustable glide according to the present embodiment has the characteristic of being able to form a relative displacement with respect to the fixed glide (100) by rotating the movable glide (200), thereby allowing the height of the leg (2) to be adjusted.

[0115] The height-adjustable glide according to the present embodiment has the characteristic that the movable housing part (211), which is the bottom surface of the movable glide (200), is formed in a rounded hemispherical shape, thereby minimizing friction with the floor, and thus allowing the movable glide (200) to be easily rotated to adjust the height even while supported on the floor.

[0116] The height-adjustable glide according to the present embodiment has the feature that the height of the leg (2) can be adjusted by easily rotating the movable glide (200) even when the leg (2) is positioned at an angle to the floor.

[0117] The height-adjustable glide according to the present embodiment has the feature that when the position of the movable glide (200) is adjusted while the leg (2) is inclined with respect to the floor, the movable guide (240) can be tilted about the axis center, but the movable guide (240) of the movable glide (200) can be easily returned to the axis center through the rotation of the lock (300), thereby ensuring sufficient durability and operational reliability.

[0118] The height-adjustable glide according to the present embodiment has the feature of preventing separation of the lock (300) and the movable glide (200) through mutual interlocking, and also preventing separation of the movable glide (200) and the fixed glide (100) through mutual interlocking.

[0120] Although specific embodiments have been described in the detailed description of the present invention, it is understood that various modifications are possible within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
