Title: Slide device

Description:
TECHNICAL FIELD 
     The present invention relates to a slide device, and more specifically, to a slide device capable of inserting a storage body in a self-closing manner and a soft-closing manner and allowing a transfer pin and a damper member to be separated so that a component and a structure are simplified. 
     BACKGROUND ART 
     Generally, sliding type storage bodies are provided with main bodies of furniture, refrigerators, various utility boxes, and the like to be openable and closable in a sliding manner so as to input and store necessary things therein. 
     The sliding type storage body is opened and closed by slide devices, which are installed between wall surfaces inside an installation space provided in a main body and both side surfaces of the storage body, and provided to be slidably movable due to a rolling contact therebetween. 
     The slide device includes a fixed rail fixedly installed on the main body and a moving rail which is provided to be slidably movable with respect to the fixed rail to guide opening and closing actions of the storage body, and a damper member configured to decrease an insertion speed and a withdrawal speed of the moving rail to be less than a predetermined speed is additionally provided on the fixed rail. 
     However, the conventional slide device has a structure in which an end portion of a rod of a damper is connected to a sub-transfer pin. In this case, the sub-transfer pin to be coupled to the end portion of the rod of the damper and a transfer pin which is rotatably coupled to the sub-transfer pin and is movable along a guide passage should be provided in a slider. 
     That is, in the conventional slide device, in addition to the generation of disadvantages in that the number of components is increased due to the above-described reasons, and a structure is complex over a predetermined level, since all of the end portion of the rod of the damper, the transfer pin, and the slider should be coupled to the sub-transfer pin, there is a disadvantage in that the durability of the slide device is degraded when the slide device moves back and forth for a long time.

     Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, embodiments of the present invention may be implemented in several different forms and are not limited to the embodiments described herein. In addition, parts irrelevant to description are omitted in the drawings in order to clearly explain the embodiments of the present invention. Similar parts are denoted by similar reference numerals throughout this specification. 
     Throughout this specification, when a part is referred to as being “connected” to another part, it includes “directly connected” and “indirectly connected” via an intervening part. Also, when a certain part “includes” a certain component, this does not exclude other components unless explicitly described otherwise, and other components may in fact be included. 
     Hereafter, embodiments of the present invention will be described with reference to the accompanying drawings. 
     A slide device  1000  according to the present invention is provided to smoothly and slidably move a drawer of a drawer type refrigerator or various furniture in a front-rear direction. Specifically, the present invention has a structure in which a user may push a storage body in a withdrawn state to perform self-closing of the storage body in the main body, and additionally, the storage body may perform soft-closing due to a buffer force of a damper  600 . 
     In this case, “self-closing” refers that the storage body in the withdrawn state is automatically inserted by simply pushing the storage body when a user wants to insert the storage body, and “soft-closing” refers to a state in which a speed B is relatively less than a speed A, wherein the storage body is initially inserted into the main body at the speed A, after inserted thereinto to a predetermined extent, and finally inserted thereinto at the speed B. 
       FIG. 1  shows a perspective view and a partially enlarged view illustrating a slide device according to one embodiment of the present invention,  FIG. 2  is a perspective view illustrating some parts of the slide device according to one embodiment of the present invention, and  FIG. 3  is an exploded view illustrating some parts of the slide device according to one embodiment of the present invention. 
     Referring to  FIGS. 1 to 3 , the slide device  1000  includes a fixed rail  100  fixedly installed on the main body, a moving rail  200  provided to be slidably movable with respect to the fixed rail  100  and configured to guide an opening or closing action of the storage body, a body  300  which is provided in an end region of one side of the fixed rail  100  and in which a guide passage  310  is provided, a slider  400  which is coupled to the body  300  and is selectively and slidably movable in a longitudinal direction of the body  300  when the moving rail  200  slidably moves, a transfer pin  500  which is rotatably coupled to the slider  400  and is movable along the guide passage  310 , an elastic member  700  disposed between and connected to the body  300  and the slider  400  and elastically compressed or expanded when the slider  400  moves, and the damper  600  which is provided on the body  300  and of which an end portion of a rod  620  is connected to the slider  400 . 
     The fixed rail  100  is fixable to an inner wall of the main body such as an inner wall of a refrigerator or furniture through a screw and the like. The moving rail  200  is connected to the storage body so that the storage body is inserted into or withdrawn from the main body, and the moving rail  200  is provided to be slidably movable with respect to the fixed rail  100 . The moving rail  200  is fixable to the storage body using a separate bracket (not shown). 
       FIG. 4  shows a front view of the body, a rear view of the slider, and an enlarged view illustrating some parts of the slider according to one embodiment of the present invention,  FIG. 5  shows a perspective view and a side view illustrating the transfer pin according to one embodiment of the present invention, and  FIG. 6  shows front, rear, and partially enlarged views illustrating the slide device according to one embodiment of the present invention. 
     Referring to  FIGS. 4 to 6 , the body  300  is provided to be fixed to an end region of one side, specifically, a rear end region, of the fixed rail  100  and includes the guide passage  310  and a damper accommodation part  320 . 
     The guide passage  310  includes a first guide passage  311  formed to extend in the longitudinal direction of the body  300  and a second guide passage  312  connected to the first guide passage  311  in an end region of the first guide passage  311  and provided to be bent with respect to the first guide passage  311 . 
     In a state in which the moving rail  200  is withdrawn, a lower protrusion  540  of the transfer pin  500 , which will be described below, is in a state of being positioned on an inner fixed surface S of the second guide passage  312 . Then, when the moving rail  200  performs an insertion action, a position of the lower protrusion  540  is changed to a side of the first guide passage  311  from a position on the inner fixed surface S of the second guide passage  312  due to coupling of a transfer pin fixing part  210  provided on the moving rail  200  and an upper protrusion  530  of the transfer pin  500  provided on the slider  400  when the moving rail  200  moves. 
     A round having a predetermined curvature or more may be formed at a corner portion in which the first guide passage  311  and the second guide passage  312  are connected to smoothly perform movement of the lower protrusion  540 , that is, to move the lower protrusion  540  to the first guide passage  311  from the position on an inner side of the second guide passage  312 . In addition, the first guide passage  311  and the second guide passage  312  may be provided to form an acute angle therebetween so as to improve restrainability with respect to the transfer pin  500 . 
     The damper accommodation part  320  may be formed to extend in the longitudinal direction of the body  300  and be parallel to the guide passage. In addition, the damper accommodation part  320  may have a space accommodating a housing  610  of the damper  600 , which will be described below, and be formed in a shape corresponding to the housing  610 . In addition, a groove part through which the rod  620  of the damper  600  may pass may be formed in one end portion of the damper accommodation part  320 . That is, the housing  610  is formed to be fixedly accommodated in the damper accommodation part  320 , the one end portion of the rod  620  is positioned in the housing  610 , and the other end portion is fixed to the slider  400 , which will be described below, to be movable with the slider  400  in a longitudinal direction. 
       FIGS. 7 to 9  are front views illustrating an operational process when the slide device performs the insertion action according to one embodiment of the present invention. 
     Referring to  FIGS. 7 to 9 , in the present invention, when the moving rail  200  performs the insertion action, the lower protrusion  540  of the transfer pin  500  coupled to the slider  400  moves along the first guide passage  311 . In this case, a state in which the upper protrusion  530  is coupled to the transfer pin fixing part  210  is maintained, and a self-closing action is performed by an elastic restoring force of the elastic member  700  which will be described below. In addition, when the self-closing action is performed as described above, a soft-closing action may also be performed due to a buffer force of the damper  600 . 
     In addition, when the moving rail  200  performs the insertion action, the upper protrusion  530  of the transfer pin  500 , which will be described below, enters an eccentric moving groove  211  of the transfer pin fixing part  210 , specifically, enters a first eccentric moving groove  212 . In this case, the lower protrusion  540  of the transfer pin  500  is positioned inside the second guide passage  312 . 
     Then, when the moving rail  200  further moves thereinto, that is, due to the self-closing action performed by the elastic member  700 , an arrangement position of the upper protrusion  530  is eccentrically changed to an inner side of the second eccentric moving groove  213 . In this case, the lower protrusion  540  is positioned inside the first guide passage  311  due to eccentric movement of the upper protrusion  530 . Accordingly, since hooking of the lower protrusion  540  is released, the transfer pin  500  rotatably coupled to the slider  400  enters a state in which the transfer pin  500  is movable along the first guide passage  311  with the slider  400 . 
     Then, when the moving rail  200  further moves thereinto, the lower protrusion  540  further moves rearward along the first guide passage  311 . In this case, the slider  400  and the transfer pin  500  are moved rearward by an elastic restoring force of the elastic member  700 . In this case, while self-closing is performed on the moving rail  200  due to the elastic restoring force of the elastic member  700 , soft-closing may also be performed thereon due to the buffer force of the damper  600 . 
     That is, in the present invention, by using the elastic restoring force of the elastic member  700  and the buffer force of the damper  600 , the self-closing and the soft-closing can be performed on the moving rail  200 . 
     Referring to  FIGS. 1 to 6 , the slider  400  is coupled to the body  300  and provided to be selectively movable in the longitudinal direction of the body  300  when the moving rail  200  slidably moves. More specifically, in a state in which the moving rail  200  is completely withdrawn from the fixed rail  100 , a state in which the slider  400  is stopped with respect to the body  300  is maintained. When the moving rail  200  is withdrawn while performing the insertion action or in an inserted state, the slider  400  slidably moves along the body  300 . Meanwhile, since the transfer pin  500 , which will be described below, is in a state of being coupled to the slider  400 , the transfer pin  500  also moves in conjunction with the slider  400  when the slider  400  moves. 
     The elastic member  700  is provided to be disposed between and connected to the body  300  and the slider  400  and elastically compressed or expanded when the moving rail  200  moves. Specifically, when the slider  400  and the transfer pin  500  move rearward due to the insertion action of the moving rail  200 , a length of the elastic member  700  gradually decreases due to the restoring force. Conversely, when the slider  400  and the transfer pin  500  move forward due to a withdrawal action of the moving rail  200 , the elastic member  700  gradually expands. While the moving rail  200  is withdrawn, the lower protrusion  540  of the transfer pin  500  moves along the first guide passage  311  and enters the second guide passage  312 . In this case, the upper protrusion  530  also eccentrically and laterally moves to the first eccentric moving groove  212  from inside the second eccentric moving groove  213  of the transfer pin fixing part  210 . Due to the movement of the upper protrusion  530 , the moving rail  200  may be separable from the slider  400  and be completely withdrawn forward. 
     Referring to  FIGS. 1 to 6 , the transfer pin  500  is rotatably coupled to the slider  400  and provided to move along the guide passage with the slider  400  when the moving rail  200  slidably moves. 
     More specifically, the transfer pin  500  includes a pin body  510 , a rotating shaft part  520  formed on one end portion of the pin body  510  and coupled to the slider  400 , the upper protrusion  530  formed on the other end portion of the pin body  510  to protrude from one surface of the pin body  510  and be insertable into a through part  410  formed in the slider  400 , and the lower protrusion  540  formed on the other end portion of the pin body  510  to protrude from the other surface the pin body  510  to correspond to the upper protrusion  530  and be movable along the guide passage when the slider  400  moves. That is, the transfer pin  500  is coupled to the slider  400  to be rotatable about the rotating shaft part  520 . 
     The upper protrusion  530  is provided to be insertable into the through part  410  formed in the slider  400 . In this case, the through part  410  is formed to extend in a direction intersecting a direction in which the slider  400  moves with respect to the body  300 , and the upper protrusion  530  is movable in a longitudinal direction of the through part  410  having a long hole shape. 
     More specifically, when the moving rail  200  performs the insertion action, the upper protrusion  530  enters the first eccentric moving groove  212  of the transfer pin fixing part  210 , which will be described below, and while the moving rail  200  performs the insertion action, the upper protrusion  530  moves into and enters the second eccentric moving groove  213 . In this case, the lower protrusion  540  is positioned inside the second guide passage  312 , and as described above, moves into the first guide passage  311  according to the movement of the upper protrusion  530 . Accordingly, the transfer pin fixing part  210 , the transfer pin  500 , and the slider  400  fixedly provided on the moving rail  200  are integrally movable (in an insertion direction of the moving rail  200 ). 
     The lower protrusion  540  is provided under the pin body  510  to correspond to the upper protrusion  530 , and as described above, the arrangement position of the lower protrusion  540  is changed to the first guide passage  311  from a position on the inner fixed surface S of the second guide passage  312  in conjunction with movement of the upper protrusion  530  due to coupling with the transfer pin fixing part  210 . 
     Meanwhile, referring to  FIG. 6 , an angle θ 1  formed by the inner fixed surface S of the second guide passage  312  to which the lower protrusion  540  is fixed and a line L connecting the lower protrusion  540  and the rotating shaft part  520  may be in the range of 70° to 120°. That is, in a state in which the lower protrusion  540  is fixed to the inner fixed surface S of the second guide passage  312 , an angle formed by the fixed surface S and the line L connecting the lower protrusion  540  and the rotating shaft part  520  is 70°. In a state in which the lower protrusion  540  is moved to the first guide passage  311 , an angle formed by the fixed surface S and the line L connecting the lower protrusion  540  and the rotating shaft part  520  is 120°. 
     In a case in which the angle θ 1  formed by the fixed surface S and the line L connecting the lower protrusion  540  and the rotating shaft part  520  is in the range and the slide device  1000  is operated, restrainability with respect to the transfer pin  500  may be improved, and a loosening phenomenon of the transfer pin  500  due to vibration and the like may be prevented so that the operating performance of the slide device  1000  may be improved. In a case in which the angle θ 1  formed by the fixed surface S and the line L connecting the lower protrusion  540  and the rotating shaft part  520  is out of the range, although the operating performance of the transfer pin  500  may be improved, since the slide device  1000  is vulnerable to a loosening phenomenon due to vibration and the like, the overall operating performance of the slide device  1000  may be degraded. 
     In addition, in a state in which the lower protrusion  540  is positioned on the second guide passage  312 , an angle θ 2  at which the transfer pin  500  is rotatable about the rotating shaft part  520  may be in the range of 10° to 45°. 
     When the angle θ 2  at which the transfer pin  500  is rotatable about the rotating shaft part  520  is less than 10°, restrainability of the second guide passage  312  with respect to the transfer pin  500  may be degraded, and the slide device  1000  may be vulnerable to a loosening phenomenon and the like due to vibration and the like, and when the angle θ 2  at which the transfer pin  500  is rotatable about the rotating shaft part  520  is greater than 45°, since smooth position movement of the transfer pin according to the insertion action of the moving rail is not possible, the operating performance of the slide device  1000  may be degraded. 
     Meanwhile, referring to  FIGS. 7 to 9 , the transfer pin fixing part  210  configured to come into contact with the slider  400  and the transfer pin  500  when the moving rail  200  slidably moves is provided on an end portion of one side of the moving rail  200 . 
     The transfer pin fixing part  210  includes the eccentric moving groove  211  configured to accommodate the upper protrusion  530  of the transfer pin  500  so as to slidably move the upper protrusion  530  of the transfer pin  500  to be in a state of being eccentrically moved in a predetermined radius while the transfer pin  500  is slidably moved by the slider  400 . 
     The eccentric moving groove  211  includes the first eccentric moving groove  212 , which is provided to extend in a longitudinal direction of the transfer pin fixing part  210  to accommodate the upper protrusion  530  of the transfer pin  500  when the moving rail  200  moves, and the second eccentric moving groove  213  provided to be bent from an end portion of the first eccentric moving groove  212 . 
     A bending direction of the second guide passage  312  with respect to the first guide passage  311  and a bending direction of the second eccentric moving groove  213  with respect to the first eccentric moving groove  212  are opposite. In an initial state in which the moving rail  200  moves to be inserted, the upper protrusion  530  enters the first eccentric moving groove  212 , and the lower protrusion  540  is in a state of being positioned in the second guide passage  312 . Then, when the moving rail  200  moves further in the direction in which the moving rail  200  is inserted, the upper protrusion  530  eccentrically moves into the second eccentric moving groove  213 , and the lower protrusion  540  is in a state of being positioned in the first guide passage  311 . 
     Referring to  FIGS. 3 and 4 , the damper  600  includes the housing  610  insertion-coupled to the damper accommodation part  320  of the body  300  and the rod  620  which is provided to be movable from the housing  610  in the longitudinal direction and whose one end portion is fixed to the slider  400 . 
     Specifically, a first coupling part  621  and a second coupling part  622  respectively and fixedly insertion-coupled to a first insertion part  420  and a second insertion part  430  of the slider  400 , which will be described below, are provided on one end portion of the rod  620 , and a neck part  623  concavely recessed to relatively decrease a cross sectional area thereof is provided between the first coupling part  621  and the second coupling part  622 . In this case, the first coupling part  621  may have a rectangular hexahedron or cylindrical shape formed on the end portion of the rod  620 , the second coupling part  622  may have a cylindrical shape around the rod  620 , and a cross sectional area of the rod is less than a cross sectional area of the second coupling head. 
     The first insertion part  420  formed to be insertion-coupled to the first coupling part  621  and the neck part  623  of the end portion of the rod  620  and the second insertion part  430  formed to be coupled to the second coupling part  622  are provided at one side of the slider  400 . 
     Specifically, the first insertion part  420  may be formed in a shape corresponding to the first coupling part  621  and the neck part  623  of the end portion of the rod  620 , and include a neck part insertion groove  421  through which the neck part  623  passes. In this case, the first insertion part  420  may be substantially formed in a “C” shape when viewed from the front. Accordingly, in a state in which the end portion of the rod  620  of the damper  600  is insertion-coupled to the slider  400 , the first coupling part  621  and the neck part  623  are in a state of being inserted into the first insertion part  420  of the slider  400 . In this case, the rod  620  of the damper  600  is hooked on the neck part insertion groove  421  having a relatively small width so that the rod  620  is coupled to the neck part insertion groove  421 . That is, due to coupling of the first coupling part  621  and the first insertion part  420 , the end portion of the rod  620  is firmly fixed in the longitudinal direction. 
     In addition, the second insertion part  430  may be provided to be spaced apart from the first insertion part  420  and formed in a shape corresponding to the second coupling part  622 . In this case, the second insertion part  430  may be substantially formed in a “U” shape when viewed from the side. That is, an inner surface  431  of the second insertion part  430  is formed in a shape corresponding to an outer surface of the second coupling part  622  and may be formed in a curved surface. 
     In addition, an insertion groove may be formed between column parts  432  of both sides of the second insertion part  430  so that the second coupling part  622  may be inserted into the second insertion part  430 . In this case, a minimum distance D 1  between the column parts  432  of the both sides may be less than a diameter D 2  of the second coupling part  622 . 
     In addition, inclined portions  433  which come into contact with the second coupling part  622  to guide the second coupling part  622  to enter the second insertion part  430  when the second coupling part  622  is coupled to the second insertion part  430  may be formed on upper ends of the column parts  432 . Since the distance between the inclined portions  433  decreases in a direction toward lower portions of the column parts  432  from upper portions thereof, the second insertion part  430  can be guided to more easily enter the second insertion part  430 . 
     Accordingly, when the second coupling part  622  is coupled inside the second insertion part  430 , a hooking sensation is generated, and in this case, the second coupling part  622  is seated in and coupled to the second insertion part  430  while the column parts  432  of both sides of the second insertion part  430  are being widened. After the second coupling part  622  is coupled inside the second insertion part  430 , the column parts  432  of both sides are restored to original positions and more firmly fix the second coupling part  622 . That is, due to the coupling of the second coupling part  622  and the second insertion part  430 , the end portion of the rod  620  is more firmly fixed in a width direction. 
     In the present invention, since the end portion of the rod  620  of the damper  600  is formed to be directly connected to the slider  400 , a structure of the transfer pin  500  may be simplified, and since a structure is provided in which the transfer pin  500  is rotatable with respect to the slider  400  while the moving rail  200  is moving back and forth, a coupling structure between peripheral components and the transfer pin  500  is further simplified so that the durability of the transfer pin  500  may be improved in addition to easy coupling and separation. In addition, in the present invention, for example, when compared to a case in which the end portion of the rod  620  of the damper  600  is directly coupled to the transfer pin  500 , since the slide device  1000  does not have a structure in which an impact due to an action of the damper  600  is directly transferred to the transfer pin  500 , the slide device  1000  has much higher durability. 
     For example, in a case in which the end portion of the rod  620  of the damper  600  is connected to the transfer pin  500 , a coupling structure to be coupled to the end portion of the rod  620  of the damper  600  and a coupling structure to be coupled to the slider  400  should be provided on the transfer pin  500 . Accordingly, a disadvantage is generated in that a structure of the transfer pin  500 , whose size is relatively small, becomes complex, and since both of the end portion of the rod  620  of the damper  600  and the slider  400  are coupled to the transfer pin  500 , a disadvantage is also generated in that the durability of the transfer pin  500  is degraded when the transfer pin  500  moves back and forth for a long time. In addition, since details are required for a process of manufacturing the transfer pin  500  having the relatively small size, there is a difficulty in the manufacturing. 
       FIG. 10  is a perspective view illustrating a slide device according to another embodiment of the present invention, and  FIG. 11  shows a front view of a body, a rear view of a slider, and an enlarged view illustrating some parts of the slider according to another embodiment of the present invention. 
     Referring to  FIG. 10 , an elastic member  700  of a slide device  1000  is provided between and connected to a body  300  and a slider  400 , and elastically compressed or expanded when a moving rail  200  moves. In this case, the elastic member  700  may be provided to be installed at any one of upper and lower sides of the body  300 . 
     In addition, referring to  FIG. 11 , a damper  600  includes a housing  610 , which is insertion-coupled to a damper accommodation part  320  of the body  300 , and a rod  620  which is provided to be movable from the housing  610  in a longitudinal direction and whose one end portion is fixed to the slider  400 . 
     Specifically, a first coupling part  621  and a second coupling part  622  respectively and fixedly coupled to a first insertion part  420  and a second insertion part  430  of the slider  400 , which will be described below, are provided on one end portion of the rod  620 , and a neck part  623  concavely recessed to relatively decrease a cross sectional area thereof is provided between the first coupling part  621  and the second coupling part  622 . In this case, the first coupling part  621  may have a rectangular hexahedron or cylindrical shape formed on an end portion of the rod  620 , the second coupling part  622  may have a cylindrical shape around the rod  620 , and a cross sectional area of the rod is less than a cross sectional area of the second coupling head. 
     A first insertion part  420  formed to be insertion-coupled to the first coupling part  621  and the neck part  623  of the end portion of the rod  620  and a seating part on which the second coupling part  622  is seated may be provided at one side of the slider  400 . Accordingly, due to the coupling of the first coupling part  621  and the first insertion part  420 , the end portion of the rod  620  can be firmly fixed in the longitudinal direction. 
     The above description is only exemplary, and it will be understood by those skilled in the art that the invention may be performed in other concrete forms without changing the technological scope and essential features. Therefore, the above-described embodiments should be considered as only examples in all aspects and not for purposes of limitation. For example, each component described as a single type may be realized in a distributed manner, and similarly, components that are described as being distributed may be realized in a coupled manner.
