(10) Referring to FIGS. 1 to 4, on an inside wall of a main body 10 of an oven and so on, supporting bars 110 are installed to support a drawer 20. Here, the drawer 20 is a part to store an object by being drawn out of or retracted into the main body 10. In addition, a slide rail locking device according to the present invention plays a role in coupling the supporting bar 110 installed on the inside wall of the main body 10 and a slide rail 30 fixed to a side surface or bottom surface of the drawer 20. Hereinafter, the supporting bar 110 installed on the inside wall of the main body 10 will be described in detail, prior to present a detailed description of the slide rail locking device according to the present invention.

(11) The supporting bar 110 includes a plurality of horizontal supporting bars 111 and a plurality of vertical supporting bars 112. The plurality of horizontal supporting bars 111 is a bar installed horizontally on the inside wall of the main body 10. Number of the horizontal supporting bars 111 should be greater than that of drawers 20 inserted into the body 10. It is because that the slide rail 30 fixed to the drawer 20 is to be mounted to the horizontal supporting bar 111, as will be described later herein.

(12) A plurality of vertical supporting bars 112 is disposed perpendicular to the plurality of horizontal supporting bars 111, wherein opposite ends of the plurality of horizontal supporting bars 111 are fixed to the plurality of vertical supporting bars 112. At this time, the number of the vertical supporting bars 112 needs to be at least two so that the opposite ends of the horizontal supporting bars 111 can be fixed thereto. Accordingly, the intervals between the horizontal support bars 111 are maintained as regular intervals by the vertical support bars 112, and the supporting bar 110 which is an assembly combining the horizontal supporting bars 111 and the vertical supporting bars 112 can be easily installed on the inside wall of the main body 10.

(13) Meanwhile, the horizontal supporting bar 111 includes a plurality of fixing parts 111-1 and supporting parts 111-2. The plurality of fixing parts 111-1 is disposed in parallel with each other toward the inside of the main body 10, with first ends thereof being mounted perpendicular to the vertical supporting bars 112. In addition, the supporting parts 111-2 connect second ends of the plurality of fixing parts 111-1, mounted to the vertical supporting bars 112, to each other. As will be described later herein, the slide rail locking device 100 to which the slide rail 30 is locked into is fixed by being mounted to one of the fixing parts 111-1 or the supporting parts 111-2. Accordingly, being equipped with the slide rail 30, the drawer 20 is installed inside the main body 10, and can be drawn out of or retracted into the main body 10 by the slide rail 30.

(14) Hereinafter, the first embodiment of the slide rail locking device 100 according to the present invention will be described in more detail, referring to FIGS. 1 to 4.

(15) The slide rail locking device 100 includes an upper locking plate 101, a lower locking plate 103, a connection plate 102, an extended plate 104, and an inclined plate 105. The upper locking plate 101 is located above the supporting bar 110 (in more detail, above the fixing part 111-1), and is locked into the slide rail 30. In addition, the upper locking plate 101 is a part to which the slide rail 30 is mounted, and the slide rail 30 fixed to the side surface or the bottom surface of the drawer 20 may be mounted to an upper surface of the upper locking plate 101. In addition, a lower locking plate 103 is located below the supporting bar 110 (in more detail, below the fixing part 111-1), and may be disposed in parallel with the upper locking plate 101.

(16) A connection plate 102 is an element connecting the upper locking plate 101 and the lower locking plate 103. Accordingly, the slide rail locking device 100 is formed to surround the fixing part 111-1 by the upper locking plate 101, the lower locking plate 103, and the connection plate 102. At this time, it is desirable for the connection plate 102 to be disposed at a side of the fixing part 111-1 toward a direction opposite to a direction the supporting part 111-2 is extended from the fixing part 111-1, thereby connecting the upper locking plate 101 and the lower locking plate 103. This is to easily install the slide rail locking device 100 with the slide rail 30 being mounted thereto to the supporting bar 110.

(17) In addition, the slide rail locking device 100 is fixed to the fixing parts 111-1 at one or more places that some of the upper locking plate 101, the lower locking plate 103, and the connection plate 102 are brought into contact with the fixing parts 111-1 by a means such as welding or adhesion.

(18) An extended plate 104 is formed by being bulged down from the lower locking plate 103 to face the upper locking plate 101. That is, the extended plate 104 extends in a direction parallel to the axial direction of the 111-2 extending from the 111-1. In addition, the inclined plate 105 is formed to be inclined upward toward an associated one of the supporting parts 111-2 from a side portion of the extended plate 104. The inclined plate 105 may be formed to have elasticity.

(19) Accordingly, when coupling the device 100 to the supporting bar 110, the slide rail locking device 100 is forced to move from the inside of the main body 10 toward the supporting bar 110 installed on the inside wall of the main body 10. Accordingly, an external force is applied on the slide rail locking device 100 to be brought into contact with the fixing part 111-1, whereby the supporting part 111-2 and the inclined plate 105 are brought into contact with each other. Thereafter, provided the external force is consistently applied, the inclined plate 105 is elastically deformed and spread downwards. Provided the slide rail locking device 100 is brought into contact completely with the fixing part 111-1 passing through the supporting part 111-2, the inclined plate 105 is elastically restored again to be inclined upwards.

(20) After the inclined plate 105 is restored, an end surface of the inclined plate 105 and the supporting part 111-2 are brought into contact with each other. That is, after the slide rail locking device 100 is mounted to the supporting bar 110, the end surface of the inclined plate 105 and the outer circumference surface of the supporting part 111-2 are brought into contact with each other. Accordingly, the slide rail locking device 100 can be easily mounted to the supporting bar 110 by the elastic deformation of the inclined plate 105. In addition, after the slide rail locking device 100 is mounted to the supporting bar 110, the slide rail locking device 100 is difficult to be separated from the supporting bar 110. Accordingly, coupling of the slide rail locking device 100 and the supporting bar 110 is easily and reliably accomplished according to the present invention.

(21) A gap of a preset distance may be formed between the slide rail locking device 100 and the vertical supporting bar 112. That is, being separated from the vertical supporting bar 112 by the preset distance, the upper locking plate 101, the lower locking plate 103, and the connection plate 102 are fixed to the fixing part 111-1. Accordingly, transferring of a movement of the slide rail locking device 100 caused by a drawing motion of the drawer 20 to a vertical supporting bar may be reduced in the present invention. Accordingly, it may prevent locking force of the locking device from becoming weak due to consistent movement and, particularly, it may prevent the slide rail locking device 100 from being deformed, or detached from the supporting bar 110 due to collision against the vertical supporting bar 112.

(22) In addition, the slide rail locking device 100 may be prevented from being deformed or from being detached from the supporting bar 110, specifically the fixing part 111-1, by preventing torsional stress caused by a drawing motion of the drawer 20 being drawn out of and retracted into the main body 10 from being concentrated on the slide rail locking device 100.

(23) FIG. 5 is a perspective view of a slide rail locking device according to a second embodiment of the present invention, FIG. 6 is a bottom view of the slide rail locking device according to the second embodiment of the present invention, and FIG. 7 is a side view of the slide rail locking device according to the second embodiment of the present invention.

(24) Hereinafter, the second embodiment of the slide rail locking device 100 according to the present invention will be described in more detail with reference to FIGS. 5 to 7.

(25) The slide rail locking device 100 includes a second upper locking plate 101 and a second lower locking plate 103. The second upper locking plate 101 is located above the supporting bar 110 (in more detail, above the supporting part 111-2), and is locked into the slide rail 30. The second upper locking plate 101 is a part to which the slide rail 30 is mounted, and the slide rail 30 fixed to the side surface or bottom surface of the drawer 20 may be mounted to the upper surface of the second upper locking plate 101.

(26) In addition, the second lower locking plate 103 is formed by being extended from the opposite ends of the second upper locking plate 101, and is located below the supporting bar 110 (in more detail, below the supporting part 111-2). Provided the slide rail locking device 100 is mounted to the supporting bar 110, one side of the second lower locking plate 103 is brought into contact with the fixing part 111-1. Accordingly, a location of the slide rail locking device 100 is fixed on the supporting bar 110.

(27) That is, the slide rail locking device 100 of the second embodiment is not provided with a separate connection plate 102 differently from the first embodiment, and is a structure wherein the second upper locking plate 101 and the second lower locking plate 103 are directly connected.

(28) The second upper locking plate 101 includes an upper supporting part 111 and a bent part 112. The upper supporting parts 111 is formed at opposite ends of the second upper locking plate 101, and may be a semicylindrical shape to be brought into contact with an upper part of the supporting part 111-2. In addition, the bent part 112 is provided in a direction perpendicular to the supporting part 111-2, and formed to be bent downwards. The bent part 112 plays a role to fix a location of the slide rail locking device 100 on the supporting part 111-2 by being seated in a step 111-3 which will be described later.

(29) In addition, the second lower locking plate 103 includes supporting parts 113 of semicylindrical shape being in contact with a lower part of the supporting part 111-2, and the supporting part 111-2 includes the step 111-3 formed along circumference of the supporting part 111-2 and the bent part 112 is seated in.

(30) Accordingly, when coupling the slide rail locking device 100 of the second embodiment to the supporting bar 110 (in more detail, the supporting part 111-2), the slide rail locking device 100 is forced to move from the inside of the main body 10 toward the supporting bar 110 installed on the inside wall of the main body 10. At this time, it is desirable to move the bent part 112 to be seated in the step 111-3.

(31) Accordingly, when an external force is applied on the slide rail locking device 100 to bring the device into contact with the supporting part 111-2, and the second upper locking plate 101 and the second lower locking plate 103 brought contact with the supporting part 111-2 by external force are elastically deformed to be spread from each other.

(32) Thereafter, the second upper locking plate 101 and the second lower locking plate 103 are recovered so that the upper supporting parts 111 are brought into contact with the upper surface of the supporting part 111-2 and the lower supporting parts 113 are brought into contact with the lower surface of the supporting part 111-2. Accordingly, the slide rail locking device 100 is mounted to the supporting bar 110 (in more detail, the supporting part 111-2).

(33) At this time, the slide rail locking device 100 may be fixed to the supporting bar 110 (in more detail, the supporting part 111-2) at one or more places among contact places between supporting parts 111 and the supporting part 111-2, and contact places between the supporting parts 113 and the supporting part 111-2 by welding and so on

(34) When the slide rail locking device 100 as above is applied, the device has an advantage of being attached and detached more easily as described above while maintaining locking force comparing with a conventional slide rail locking device.

(35) The embodiments of the present disclosure are intended to fully describe the present disclosure to a person having ordinary knowledge in the art (named as those skilled in the art, hereinafter) to which the present disclosure pertains. Accordingly, the exemplary embodiments of the present invention are merely examples and should not be understood to limit the scope of the present invention as the present invention is not limited to foregoing embodiments and accompanying drawings.
