Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slide unit for drawers,

More particularly, the drawer side moving rails and the middle inner rails are capable of being pulled out and pulled in succession with respect to the main body side fixed rails, To a slide unit for a drawer which is capable of preventing the occurrence of shape deformation of the movable rail as much as possible.

Generally, a drawer inner rail member is provided between the main body and the drawer so that when the user opens and closes the drawer, the drawer is easily pulled out or pulled out of the main body.

For example, in the case of the three-fold folding type, the main body side fixing rail is fixed to the inner surface of the refrigerator inner wall, general furniture, etc., And the drawer side fixed rail is fixed to the housing (drawer). The drawer inner rail member includes an intermediate slide rail disposed between the main body side stationary rail and the drawer side stationary rail, and a plurality of drawers disposed between the main body side stationary rail and the intermediate slide rail, and between the drawer side stationary rail and the intermediate slide rail. And the slide ball is disposed.

However, in the related art, when the drawer side fixed rail and the intermediate slide rail are simultaneously moved to a predetermined section, the drawer side fixed rail is drawn out further outward The intermediate slide rails are not moved in a normal manner, and the intermediate slide rails are often moved after the drawer side fixed rails are moved over a predetermined distance.

Likewise, when the drawer side fixed rail is moved toward the side of the main assembly side fixed rail, the drawer side fixed rail is moved in the direction in which the drawer side fixed rail is pulled in, In the state that the intermediate slide rail does not move, the drawer side fixed rail first moved a certain distance and then the intermediate slide rail moves along the rail.

On the other hand, in the drawer-side fixed rail, an external force due to the load of the accommodating body (drawer) acts relatively larger than the intermediate slide rail and the main body side fixed rail. As described above, The external force acting on the drawer-side fixed rail becomes difficult to be sufficiently dispersed by the intermediate slide rail or the like. In this case, there arises a problem that the shape deformation of the drawer-side fixed rail and the smooth slide movement between the entire rails are interrupted do.

The sequential withdrawal of the movable rail 120 and the inner rail 130 with respect to the fixed rail 110 means that when the movable rail 120 is to be pulled out of the fixed rail 110, The movable rail 120 and the inner rail 130 are simultaneously slid outwardly with respect to the fixed rail 110 when the housing body is to be drawn out from the main body in the outward direction and then the inner rail 130 is moved Is stopped and only the moving rail 120 is slid outwardly.

Likewise, the sequential pulling-in of the movable rail 120 and the inner rail 130 to the fixed rail 110 means that the movable rail 120 is moved inward from the outside toward the fixed rail 110 side The movable rails 120 and the inner rails 130 simultaneously slide relative to the fixed rails 110 when the accommodating body is to be drawn in the lateral direction of the main body, .

That is, according to the present invention, when the moving rail 120 is to be pulled outward with respect to the fixed rail 110, the inner rails 130 are simultaneously drawn to a predetermined section, so that a considerable load proportional to the weight of the housing body moves The inner rail 130 can support the moving rail 120 more than a certain amount even if it is applied to the rail 120, so that it is possible to further prevent the shape deformation of the moving rail 120 from occurring. Accordingly, the durability of the entire slide unit 100 can be improved. Likewise, when the movable rail 120 is to be pulled in the direction of the fixed rail 110, the above-described effect occurs.

First, the fixed rail 110 can be fixed to various parts such as an inner wall surface of a refrigerator, an inner wall surface of a refrigerator, or the like using a screw or the like. Hereinafter, the fixing rail 110 will be described with reference to a refrigerator.

The inner rail 130 has an inner accommodating space like the fixed rail 110 and is provided between the movable rail 120 and the inner rail 130 and between the inner rail 130 and the fixed rail 110, A plurality of slide balls 131 are provided so as to be movable. The details of the slide movement relationship between the respective constitutions of the plurality of slide balls 131 are obvious to those skilled in the art, and a detailed description will be omitted below.

Next, the locking stopper 140 sequentially moves the moving rails 120 and the inner rails 130 to the fixed rails 110, and sequentially rotates the inner rails 130 and the moving rails 120 ) In order to induce a sequential entry.

2, the locking stopper 140 includes a rotating body 141 rotatably provided in an end region of the inner rail 130, a rotating body 141 rotatably supporting the rotating body 141, A supporter 144 fixed to an end region of the rotary body 130 and an elastic member 147 provided between the rotary body 141 and the supporter 144 to elastically rotate the rotary body 141. The locking stopper 140 can be press-fitted into one end portion of the inner rail 130 and can be prevented from being detached from the inner rail 130 through a separate release preventing member (not shown). The release preventing member may be press-fitted into the end of the inner rail 130 to prevent the lock stopper 140 from falling off.

2 to 4, the locking stopper 140 includes a first engagement hook (not shown) provided on one side of the rotation body 141 and selectively engageable with the movement rail 120, A second engaging hook 149 provided on the other side of the rotating body 141 and selectively engageable with the fixed rail 110 and a portion of the rotating body 141 which is in contact with the moving rail 120 And a second bumper 162 coupled to a portion of the rotating body 141 that is contactable with the fixed rail 110.

The rotation body 141 is rotatably coupled to the supporter 144. Specifically, the rotation body 141 is provided with a rotation axis insertion hole 142 so that a plurality of rotation shafts 145 provided in the supporter 144 can be inserted into the rotation body 141 . The rotary body 141 is rotatably coupled to the supporter 144 in a state where a plurality of rotary shafts 145 are inserted into the rotary shaft insertion hole 142.

Next, the supporter 144 is press-fitted into one end of the inner rail 130 to be rotatable and supports the rotary body 141. To this end, as described above, the supporters 144 are provided with the plurality of rotation shafts 145 so as to be inserted into the rotation shaft insertion holes 142 of the rotation body 141 from both sides.

Next, the elastic member 147 is provided between the rotating body 141 and the supporter 144 to elastically rotate the rotating body 141. More specifically, the supporter 144 is provided with an elastic member insertion groove 146 so that one end of the elastic member 147 can be inserted, and the elastic body 147 is inserted into the elastic body 147, An insertion groove 143 is provided. Accordingly, the rotating body 141 is rotatable about a portion coupled to the plurality of rotation shafts 145. The elastic member 147 elastically biases the rotary body 141 such that the end of the rotation body 141 is rotatable toward the fixed rail 110, And the end portion thereof is rotatable in a direction away from the fixed rail 110 by an external force.

In the present invention, the elastic member 147 can be applied as long as it has an elastic force equal to or greater than a certain level. For example, the elastic member 147 can be applied as a spring, a rubber, or the like. Hereinafter, the present invention will be described and illustrated with reference to a case where the spring is applied for the sake of convenience and convenience.

Next, the first hooking hook 148 is provided on one side of the rotating body 141, and is selectively engageable with the moving rail 120. The second hooking hook 149 is provided on the other side of the rotating body 141 and is selectively engageable with the fixed rail 110. The first hooking hook 148 is provided on an upper area of the one end of the rotating body 141 and the second hooking hook 149 is provided on the lower end area of the rotating body 141 do.

5 to 9, a first through hole 121 is formed at one side of the movable rail 120. The first hook 148 is connected to the first through hole 121, As shown in FIG. A second through hole 111 is formed in one side of the fixed rail 110 and a second hook 149 is selectively engageable with the second through hole 111.

The engagement relationship and the mutual slide operation of the fixed rail 110, the inner rail 130, and the movable rail 120 will be described as follows.

5 to 7, when the movable rail 120 and the inner rail 130 are pulled out from the fixed rail 110, that is, when the housing 20 is moved outward from the main body 10 The movable rail 120 and the inner rail 130 are simultaneously drawn out in a state where the first latching hook 148 is engaged with the first through hole 121. [ When the movable rail 120 and the inner rail 130 are simultaneously drawn along the longitudinal direction of the fixed rail 110 and the second hooking hook 149 of the locking stopper 140 reaches the upper side of the second through hole 111 The second hooking hook 149 rotates in the downward direction and is hooked on the side surface of the second through hole 111. [ The locking stopper 140 is rotated by the elastic force of the elastic member 147 so that the second hooking hook 149 is caught on the side surface of the second through hole 111. [ In this case, the relative slide movement of the inner rail 130 relative to the fixed rail 110 is blocked by the engagement of the second hook 149. The mutual engagement between the first engagement hook 148 and the first through hole 121 is released by the rotation of the locking stopper 140 so that the movable rail 120 is slid relative to the inner rail 130 .

That is, according to the present invention, due to the interlocking relationship between the first hook 148 and the first through hole 121, and the mutual interlocking relationship between the second hooking hook 149 and the second through hole 111, 120 and the inner rail 130 to the fixed rail 110 in a sequential manner.

For example, unlike the present invention, when the movable rail 120 is first drawn out and the inner rail 130 is drawn out when the movable rail 120 is to be drawn out from the fixed rail 110, A considerable external force is applied to the movable rail 120 due to the load, which may cause problems such as the shape deformation of the movable rail 120 and the smooth sliding movement between the rails. Since the movable rail 120 and the inner rail 130 can be sequentially drawn out, the external force applied to the movable rail 120 can be partially dispersed toward the inner rail 130, It is possible to further prevent the shape deformation and to maintain smooth slide movement of the moving rails 120 and the inner rails 130 for a long period of time.

8 and 9, when the movable rail 120 and the inner rail 130 are moved in the pulling direction of the fixed rail 110, that is, when the housing 20 is moved toward the main body 10 side When it is desired to pull in, the moving rail 120 moves along the inner rail 130 in the direction in which the moving rail 120 is drawn in. When the movable rail 120 moves and the end of the movable rail 120 moves to the area where the locking stopper 140 is located and pushes the upper end of the locking stopper 140, 120). The locking stopper 140 maintains the second hooking hook 149 engaged with the second through hole 111 and pushes the upper region by the end of the moving rail 120 as described above, And is rotated clockwise. The first latching hook 148 of the locking stopper 140 is engaged with the first through hole 121 of the movable rail 120 and the second latching hook 149 of the locking stopper 140 is engaged with the first through- The through hole 111 is in the engaged state. That is, the movable rail 120 is in a state in which the movable rail 120 can slide in conjunction with the inner rail 130. The movable rail 120 and the inner rail 130 are moved along the fixed rail 110 at the same time when the movable rail 120 is further moved in the drawing direction.

That is, according to the present invention, due to the mutual engagement relationship between the first engagement hook 148 and the first through-hole 121 and the mutual engagement relationship between the second engagement hook 149 and the second through-hole 111, The inner rail 120 and the inner rail 130 can be sequentially drawn into the fixed rail 110.

On the other hand, as soon as the first engagement hook 148 is engaged with the first through-hole 121 and the second engagement hook 149 is engaged with the second through-hole 111, A certain amount of impact is generated between the inner wall forming the through-hole 121 and the second through-hole 111 and the rotating body 141. As the amount of the impact increases, the rotating body 141 is cracked or severely damaged, resulting in a problem in terms of durability.

2 to 4, the locking stopper 140 includes a locking stopper 140, which is engaged with a part of the rotating body 141 that can contact the moving rail 120, 1 bumper 161 and a second bumper 162 coupled to a portion of the rotating body 141 that is in contact with the fixed rail 110.

Specifically, the first bumper 161 is provided in a part of the rotating body 141 that can contact the rear end of the movable rail 120 at the time of pulling the movable rail 120 as described above, It is possible to prevent direct contact between the movable rail 120 and the rotating body 141 made of, for example, a plastic material, thereby further preventing breakage and cracking of the rotating body 141.

The second bumper 162 is rotatably supported on the inner wall of the fixed rail 110 at the time of pulling out the movable rail 120 and the peripheral wall of the rotating body 141 to prevent direct contact between the fixed rail 110 made of a metal and the rotating body 141 made of a plastic material so that breakage and cracking of the rotating body 141 can be prevented, .

In the embodiment of the present invention, each of the first bumper 161 and the second bumper 162 is preferably made of any one of rubber, silicone, and urethane having a certain degree of ductility. The first bumper 161 and the second bumper 162 may be formed of a material having a relatively larger or smaller diameter than that of the rotating body 141. In the case where the rotating body 141 is made of either plastic or iron, It is applicable if it is made of flexible material.

3 and 4, the rotating body 141 is provided with first and second bumper coupling grooves 151 and 152 so that the first bumper 161 and the second bumper 162 can be engaged with the first bumper 161 and the second bumper 162, respectively. Here, the first bumper 161 and the second bumper 162 can be forcedly press-fitted in the first and second bumper coupling grooves 151 and 152, respectively.

In the embodiment of the present invention, the first bumper 161 and the second bumper 162 are respectively slid laterally in the first and second bumper coupling grooves 151 and 152, and the cross-sectional area is gradually expanded toward one side And contact plates 164 and 166 connected to the bumper bodies 163 and 165, respectively.

Here, the contact plate 164 of the first bumper 161 is substantially in contact with the end of the movable rail 120, and the contact plate 166 of the second bumper 162 is substantially fixed to the fixed rail 110, The second through hole 111 and the peripheral area thereof.

In the present invention, the bumper body 163, 165 has a structure in which the cross-sectional area of the bumper body 163, 165 gradually expands toward one side. Likewise, the first and second bumper coupling grooves 151, . When the first bumper 161 and the second bumper 162 are inserted into the first and second bumper coupling grooves 151 and 152 respectively, It is possible to prevent departure in a direction perpendicular to the direction in which the second bumper coupling grooves 151 and 152 are inserted.
