[0027] Embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0028] FIG. 1 is an assembled perspective view of a fixed system according to one embodiment of the present invention, and FIG. 2 is an exploded perspective view of a fixed system according to one embodiment of the present invention.

[0029] Referring to FIGS. 1 and 2, the fixing system (1000) of the present invention may be installed in a baking oven, a dishwasher, or similar items. The fixing system (1000) comprises a wire rack (10), a rail assembly (20) installed on the wire rack (10), and one or more fixing means (30) for detachably connecting the rail assembly (20) to the wire rack (10).

[0030] A wire rack (10) may be installed on the inner side wall of a baking oven, a dishwasher, or similar item. Such a wire rack (10) comprises a pair of vertical rods (11) spaced apart from each other, and at least two horizontal rods (12) connecting the vertical rods (11). The at least two horizontal rods (12) may be parallel in the horizontal direction and spaced apart from each other in the vertical direction.

[0031] The horizontal rod (12) is provided with a horizontal extension (12a) that extends in the longitudinal direction and an L-shaped bent end (12b) that is bent at both ends of the horizontal extension (12a), and the bent end (12b) at both ends can be connected to a pair of vertical rods (11) respectively.

[0032] Meanwhile, the rail assembly (20) can be detachably installed on the wire rack (10).

[0033] The rail assembly (20) includes a fixed rail (21) installed on a wire rack (10) and one or more movable rails (22) slidably coupled to the fixed rail (21). Accordingly, the rail assembly (20) is configured such that, as needed, one or more movable rails (22) slide rearward or forwardward to retract or withdraw a basket (not shown) coupled to the movable rail (22).

[0034] The fixed rail (21) can be detachably installed on the wire rack (10) by one or more fixing means (30). These fixing means (30) include a first fixing clip (100) coupled to the rear side of the fixed rail (21) and a second fixing clip (22) coupled to the front side of the fixed rail (21). That is, the fixed rail (21) can be detachably installed on the wire rack (10) by the first fixing clip (100) and the second fixing clip (200).

[0035] According to one embodiment, when a fixed rail (21) is installed on a wire rack (10), a first fixing clip (100) is first mounted horizontally on a rear vertical rod (11) of the wire rack (10), and then a second fixing clip (200) is mounted vertically on a front horizontal rod (12) of the wire rack (10) (the order of separation is the reverse of the order of installation). That is, the first fixing clip (100) and the second fixing clip (200) can be formed in a mutually complementary structure so that the fixed rail (21) can be installed more easily on the wire rack (10) while simultaneously being easy to separate.

[0036] FIGS. 3(a) and (b) are respectively a combined perspective view of a first fixing clip and a perspective view of a first fixing clip according to one embodiment of the present invention, FIGS. 4(a) and (b) are respectively a combined side view of a first fixing clip and a combined plan view of a first fixing clip according to one embodiment of the present invention, and FIGS. 5(a) to (c) are respectively a plan view, a side view, and a front view of a first fixing clip according to one embodiment of the present invention.

[0037] Referring to FIGS. 3 to 5, the first fixing clip (100) of the present invention is installed on the rear side of the wire rack (10) and includes a first support section (110), a mounting section (120), and a first rail coupling section (130).

[0038] More specifically, the first fixing clip (100) is configured to include a first support section (110) that partially surrounds the rear horizontal rod (12) and is supported by the rear horizontal rod (12), a mounting section (120) that is connected to one side of the first support section (110) and is mounted on the rear vertical rod (11), and a first rail coupling section (130) that is connected to the other side of the first support section (110) and is coupled with the fixing rail (21).

[0039] The first support section (110) partially engages with the circumference of the rear horizontal rod (12) and includes a first support member (111) supported on the upper end of the horizontal rod (12) and a second support member (112) supported on one side of the horizontal rod (12). That is, the first support member (111) may be a horizontal plate supported on the upper end of the horizontal rod (12), and the second support member (112) may be a vertical plate connected downward from the first support member (111) and supported on one side of the horizontal rod (12).

[0040] The mounting section (120) is connected to the first support section (110) and is mounted on the rear vertical rod (11). This mounting section (120) surrounds the rear vertical rod (11) but is formed to be open in the rear direction, so that the mounting section (120) can be mounted by being pushed horizontally, i.e., in the rear direction, relative to the vertical rod (11).

[0041] These mounting sections (120) include a first side (121), a second side (122), and a connecting part (123).

[0042] More specifically, the mounting section (120) is configured to include a first side (121) that is connected to the support section (110) and supports one side of the vertical rod (11), a second side (122) that faces the first side (121) and supports the other side of the vertical rod (11), and a connecting part (123) that connects the first side (121) and the second side (122) and surrounds the vertical rod (11).

[0043] That is, the mounting section (120) has a first side (121), a second side (122), and a connecting part (123) that surround the vertical rod (11), and is open to the rear so that the vertical rod (11) can enter.

[0044] According to one embodiment, a latching portion (122a) may be provided on the inner side of the second side (122) so as to be convex toward the first side (121) facing it, thereby inducing a catch when the vertical rod (11) enters and preventing detachment after mounting on the vertical rod (11).

[0045] At this time, the shortest distance (d2) between the latching portion (122a) and the first side portion (121) can be formed to be smaller than the diameter (d1) of the vertical rod (11). That is, since the latching portion (122a) is formed convexly toward the first side portion (121), it performs a locking function when coupled to the vertical rod (11). Therefore, as the vertical rod (11) enters, the latching portion (122a) is elastically pushed outward by the vertical rod (11), and when the entry of the vertical rod (11) is completed, the latching portion (122a) elastically returns to its original position and latches the vertical rod (11).

[0046] According to one embodiment, a guide portion (122b) may be further provided on the inner side of the second side (122), connected to the latching portion (122a) and formed to spread outward to guide the entry of the vertical rod (11). Since this guide portion (122b) is formed to spread outward from the first side (121) as it extends toward the rear side after opening, the entry of the vertical rod (11) may be facilitated.

[0047] As the second side (122) is provided with a latching portion (122a) and a guide portion (122b), the mounting section (120) can be formed in a planar shape of approximately “R” as shown in FIG. 4.

[0048] Meanwhile, when the mounting of the first fixing clip (100) is completed, as shown in FIG. 4, the mounting section (120) is mounted on the rear vertical rod (11), and the upper end of the mounting section (120) is supported on the lower end of the upper horizontal rod (12), preferably the upper bent end (12b). In addition, the first support part (111) of the first support section (110) is supported on the upper end of the lower horizontal rod (12), and the second support part (112) can be supported on one side of the lower horizontal rod (12).

[0049] The first rail coupling section (130) may be a plate extending horizontally from the first support section (110), more specifically from the second support member (112), and the rear side of the fixed rail (21) may be seated and coupled to the upper part of the first rail coupling section (130).

[0050] FIGS. 6 (a) to (c) are respectively a combined perspective view of a second fixing clip, a perspective view of a second fixing clip, and a combined side view of a second fixing clip according to an embodiment of the present invention, FIGS. 7 (a) to (c) are respectively a top view, a side view, and a front view of a second fixing clip according to an embodiment of the present invention, and FIGS. 8 (a) to (c) are drawings showing the contact state between the second fixing clip and the horizontal rod according to the diameter of the horizontal rod according to an embodiment of the present invention.

[0051] Referring to FIGS. 6 to 8, the second fixing clip (200) of the present invention is installed on the front side of the wire rack (10) and includes a second support section (210), a hook section (220), and a second rail coupling section (230).

[0052] More specifically, the second fixing clip (200) is configured to include a second support section (210) supported on a horizontal extension (12a) of a front horizontal rod (12), a hook section (220) connected to one side of the second support section (210) and hooked onto a bent end (12b) of the front horizontal rod (12), and a second rail coupling section (230) connected to the other side of the second support section (210) and coupled with a fixing rail (21).

[0053] The second support section (210) may be a vertical plate supported on one side of the front horizontal rod (12), more specifically, the horizontal extension part (12a). This second support section (210) may include an extension support part (211) supported on both the upper horizontal extension part (12a) and the lower horizontal extension part (12a).

[0054] The hook section (220) is connected to the second support section (210) and is mounted on the front horizontal rod (12), preferably the bent end (12b). This hook section (220) surrounds the front bent end (12b) and is formed to be open in the downward direction, so that the hook section (220) can be mounted vertically, i.e., in the up-and-down direction, relative to the front bent end (12b).

[0055] These hook sections (220) include a catch portion (222), a first anti-detachment portion (221), and a second anti-detachment portion (223).

[0056] More specifically, the hook section (220) is configured to include a catch (222) supported at the top of the front bending end (12b), a first anti-detachment (221) connected to the second support section (210) and extending downward from one side of the catch (222) to prevent lateral deviation of the front bending end (12b), and a second anti-detachment (223) facing the first anti-detachment (221) and extending downward from the other side of the catch (222) to prevent lateral deviation of the front bending end (12b).

[0057] That is, the hook section (220) has a catch portion (222), a first anti-detachment portion (221), and a second anti-detachment portion (223) surrounding the front bent end (12b), but is open to the lower side so that the bent end (12b) can enter.

[0058] According to one embodiment, the catch portion (222) may be provided with a horizontal support portion (222a) supported at the top of the front bending end portion (12b), a first inclined support portion (222b) extending downwardly from the horizontal support portion (222a) to one side, and a second inclined support portion (222c) extending downwardly from the horizontal support portion (222a) to the other side.

[0059] Referring to FIG. 8, the catch portion (222) can be stably supported on the folded end portion (12b) by making one to three point contacts depending on the thickness of the folded end portion (12b). That is, the catch portion (222) can be formed in a size capable of accommodating wire racks (10) of various thicknesses.

[0060] The first anti-detachment member (221) is configured to extend downward from one side of the catch member (222), preferably from the first inclined support member (222b). Likewise, the second anti-detachment member (223) is configured to face the first anti-detachment member (221) and extend downward from the other side of the catch member (222), preferably from the second inclined support member (222c). These first anti-detachment member (221) and second anti-detachment member (223) are configured to prevent the bent end (12b) from detaching due to shaking during rail operation.

[0061] According to one embodiment, the hook section (220) may further include a third anti-detachment part (224) formed to protrude inward from the first anti-detachment part (221) to prevent downward deviation of the front bending end (12b), and a bending part (225) bent inward from the lower end of the first anti-detachment part (221). At this time, the size of the lower opening of the hook section (220), that is, the shortest distance (L2) between the second anti-detachment part (223) and the bending part (225), may be formed to be less than or equal to the shortest distance (L1) between the first anti-detachment part (221) and the second anti-detachment part (223). When the fixed rail (21) is lifted upward during rail operation, the second fixing clip (200) coupled to the fixed rail (21) is also lifted upward, and at this time, the third anti-detachment part (224) can prevent the second fixing clip (200) from detaching from or rotating from the bent end (12b). The bending part (225) is configured to minimize the amount of deformation of the third anti-detachment part (224) caused by the bent end (12b) when the second fixing clip (200) is mounted.

[0062] The second rail coupling section (230) may be a plate extending horizontally from the second support section (210), and the front side of the fixed rail (21) may be seated and coupled to the upper part of the second rail coupling section (230).

[0063] FIGS. 9 (a) to (c) is a drawing showing the mounting process of a fixed system according to one embodiment of the present invention.

[0064] Referring to FIGS. 3 to 9, the mounting section (120) of the first fixing clip (100) coupled to the rear side of the rail assembly (20) moves in a horizontal direction, that is, in the rear direction, and is lockedly mounted to the rear vertical rod (11), the upper end of the mounting section (120) is supported at the lower end of the upper horizontal rod (12), and the first supporting section (110) of the first fixing clip (100) is supported at the upper end of the lower horizontal rod (12).
