Abstract

<P>PROBLEM TO BE SOLVED: To allow a strike to be always engaged with a runner even if a sidewall of furniture is separated from a side plate of a drawer under the long-term use of the furniture. <P>SOLUTION: The strike with its lower part formed as a mounting part 61 and with its upper part formed as an engaging part 62 includes rectangular spring holes 63, 64 and screw holes 67, 67 bored in the laterally symmetrical positions of the front face of the mounting part 61. Pressing springs 65, 66 of backward curved shape to project slightly from the rear face of the mounting part 61 are integrally formed from the upper parts to the lower parts of the spring holes 63, 64. The strike is mounted to the side plate by screws so as to be engaged with the runner in the closed state of the drawer. The whole of the strike, i.e., the engaging part of the strike 60, is energized by the spring force of the pressing springs 65, 66 to separate from the side plate. Consequently, even if the side plate is deformed outward, the engagement between the strike 60 and the runner is not released. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a pull-in mechanism capable of preventing the drawer from colliding with the back vigorously when the drawer is closed in furniture with a drawer, and capable of pulling the drawer completely back.

  In recent furniture, furniture rails are attached to the sliding parts so that the drawer can be smoothly put in and out. In the furniture rail, a metal slide rail is housed in a metal guide rail, and a retainer in which a large number of ball bearings are arranged between the guide rail and the slide rail is installed. Therefore, recent furniture has very good sliding of the drawer, so if you push the drawer vigorously, the drawer will hit the back of the furniture strongly, and the reaction will cause the drawer to open a little, May have been damaged, or even things that were placed in order in the drawer may collapse.

  In view of such a problem, a retracting mechanism has been proposed in which when the drawer is closed, the pulling-out momentum is loosened to prevent it from striking the back. (Patent Documents 1 and 2)

  Here, the retracting mechanism will be described. FIG. 23 is a perspective view of the furniture provided with the retracting mechanism, FIG. 24 is a front view of the retracting device used for the retracting mechanism, FIG. 25 is a front sectional view of the same, FIG. 26 is an enlarged front view of the runner of the retracting device, FIG. Is a bottom view, FIG. 28 is a perspective view of a strike used in a conventional retracting mechanism, FIG. 29 is a diagram for explaining a normal engagement state of the runner and the strike when the drawer is closed, and FIG. FIG. 31 is a diagram for explaining a state in which the side wall bulges outward and the runner and the strike are separated, and FIG. 31 is a diagram for explaining a state in which the side wall of the furniture bulges outward.

  As shown in FIG. 23, the furniture body 10 has a box shape with the front serving as an entrance, and includes a top portion 11, a bottom portion 12, a back portion 13, and side walls 14 and 14.

  The drawer 20 has a box shape with no lid, and can be easily inserted from the insertion opening of the furniture body 10. The drawer 20 includes a front plate 21, a back plate 22, a bottom plate 23, and side plates 24 and 24. Furniture rail slide rails 25 are attached to the side plates 24, 24 of the drawer 20.

  Furniture rail guide rails 15 and 15 are attached to the inside of the side walls 14 and 14 of the furniture body 10. This guide rail allows the slide rail 25 of the drawer 20 to slide in and out. A retainer (not shown) having a large number of ball bearings is disposed between the guide rail and the slide rail in order to improve the sliding property of the slide rail.

  A retracting device 30 is attached to the inside of the side wall of the furniture body 10. The pull-in device is used to buffer the momentum of the drawer when the drawer is closed vigorously to prevent the drawer from striking the back of the furniture body, and even if the drawer is not closed completely, It can be pulled back completely.

  The retracting device will be briefly described with reference to FIGS. The retracting device 30 includes a case 31, a runner 32, a tension spring 33, and a damper 34. In the case 31, guide grooves 35 are horizontally formed on both sides in the longitudinal direction, and a tip portion is a bent portion 36 bent obliquely upward. As shown in FIGS. 26 and 27, the runner 32 has a first guide pin 37 and a second guide pin 38 protruding laterally, and these guide pins move in the guide groove 35. The runner 32 is formed with a first locking piece 39 and a second locking piece 40 protruding downward.

    The tension spring 33 has one end engaged with the runner 32 and the other end engaged with the end of the case 31, and is always pulling the runner 32 in the back (left side in FIGS. 24 and 25). It has become. In the damper 34, a piston 42 is movably disposed in a cylinder 41. A rod 43 is fixed to the piston, and the tip of the rod 43 is rotatably engaged with the runner 32. The damper 34 slows down the speed of the runner that moves vigorously by gradually letting out air when the piston 42 moves in the cylinder 41. Reference numeral 44 denotes an elongated opening formed in the lower portion of the case 31. The first locking piece 39 and the second locking piece 40 protrude from the opening and move from end to end of the opening.

  As shown in FIG. 28, the strike used in the conventional retracting mechanism, that is, the strike 50 in Patent Documents 1 and 2, has a base 51 formed with a temporary engaging step 52 and a main engaging step 53 in a stepped manner. Yes. The top portion 54 of the temporary engagement step portion 52 and the top portion 55 of the main engagement step portion 53 are inclined to rise in the standby position direction (rightward in FIG. 28). The base 51 is formed with a pair of stepped portions at symmetrical positions. The reason why the stepped portions are formed at the symmetrical positions in this way is not only attached to the left and right of the drawer. This is because when the first locking piece is engaged between the stepped portions, it is sandwiched between the stepped portions at the symmetrical positions and is difficult to come off.

  Screw holes 56 are formed on both sides of the base 51. In this conventional strike, the height from the attaching portion of the base 51, that is, the side plate of the drawer to which the strike is attached, to the main stepped portion 53 is constant.

  Here, the movement of the runner in the retracting device will be described. The runner 32 is pulled by the tension spring 33, and is located in the horizontal part of the guide groove 35 (left side in FIGS. 24 and 25). This state is a state in which the drawer is closed. When the runner 32 is moved by an external force against the spring force of the tension spring 33 (to the right in FIG. 25), the first guide pin 37 and the second guide pin 38 of the runner 32 move in the guide groove 35. . Then, as shown in FIG. 25, the first guide pin 37 is located at the end of the bent portion 36 of the guide groove 35, and the second guide pin 38 is located in the horizontal portion. In this state, since the tension spring 33 is extended for a long time, a large force for pulling back is applied to the runner 32. However, since the first guide pin 37 is hooked on the bent portion 36 of the guide groove 35, the runner 32 is locked and remains in this position even if the external force applied to the runner 32 is removed. At this time, since the runner 32 positioned on the right side of FIG. 25 is inclined, the first locking piece 39 is submerged in the case 31, and only the second locking piece 40 protrudes from the case 31. The position of the runner (right side in FIG. 25) is a standby position in a state where the drawer is opened.

  In order to move the runner 32 to the standby position (when opening the drawer) in the retracting device in which the runner 32 is at the deepest non-standby position (left in FIG. 24, 25) of the horizontal portion of the guide groove 35, strike Do. As shown in FIG. 23, when the retractor 30 is attached to the inside of the side wall 14 of the furniture body 10, the strike 50 is attached to the side plate 24 of the drawer 20. The attachment position of the strike 50 to the drawer is the position where the first locking piece 39 of the runner returned by the tension spring when the drawer is closed is engaged with the strike 50 and moved to the back of the furniture, that is, the runner 32. Is the deepest position of the guide groove 35.

  Then, when the opened drawer (runner is in the standby position) is closed, the left side surface of the temporary engagement step portion 54 of the strike 50 hits the protruding second locking piece 40 of the runner 32 of the drawing device, and the runner 32 is inclined. Correctly unlock the runner's lock. Then, the first locking piece 39 submerged in the case 31 emerges from the case 31 and is positioned between the main engagement step portions 53 and 53 of the strike 50, and the first locking piece 39 is the main engagement of the strike 50. Engage with the stepped portion 53. Then, since the runner 32 is pulled inward by the tension spring 33, the strike 50 engaged with the first locking piece 39 is pulled, and the drawer attached with the strike moves in the closing direction. At this time, since the runner 32 is attached to the damper 34, the drawer pulled by the runner is slowly closed by the damper.

  Only the main engagement step portion may be used for the strike. However, if the temporary engagement step portion is formed, the runner and the strike book will be for some reason when the drawer is opened even if the runner and the strike are in the normal position. When the engagement step portion is disengaged, the engagement can be easily performed again. That is, when the runner and the strike are disengaged, the runner returns to the non-standby position by the tension spring. At that time, once the drawer is closed and pushed a little strongly, the inclined top portion 54 of the temporary engagement step portion 52 of the strike 50 slides on the first locking piece 39 of the runner 32 and advances to the back, and the temporary engagement step portion. 52 is temporarily engaged. When the drawer is opened in this state, the runner is drawn by the strike and moves to the standby position, and the strike comes out as shown in FIG. 23, and the engagement between the runner and the strike is completely released. When the drawer is closed again, the above-described runner and strike return to normal engagement.

  By the way, when the furniture is manufactured, if the distance between the side plate of the drawer and the side wall of the main body is as designed, that is, the optimal distance for installing the rail, the retracting device, the strike, etc., as shown in FIG. The engagement between the runner 32 and the strike 50 of the retracting device 30 is appropriate. However, for many years, when a heavy object is stored in the drawer or a heavy object is placed on the furniture body, the side wall of the furniture may bulge outward. If this phenomenon is shown in an extreme diagram for convenience of understanding, it becomes as shown in FIG. That is, at the time of furniture manufacture, the side wall 14 of the furniture is straight as shown by the solid line in FIG. 31, but it swells outward like a two-dot chain line over the years, and the space between the side wall 14 of the furniture and the drawer side plate 24 is It spreads. Then, as shown in FIG. 30, the runner 32 of the retractor 30 attached to the side wall of the furniture and the strike 50 attached to the side plate of the drawer are separated so that the runner and strike cannot be engaged, and the runner is always in the non-standby position. The function of the retracting device cannot be performed at all.

  For furniture, if a heavy object is stored in the drawer, the drawer may go down slightly over the years. In such a case, in the furniture in which the retracting mechanism is installed, the strike attached to the drawer is lowered, so that it may be detached from the runner and cannot be normally engaged with the runner.

  The present inventor, if the strike engagement portion that engages with the runner is spaced from the side wall of the furniture and the side plate of the drawer, if the strike position can always engage with the runner, The present invention has been completed by focusing on the fact that the strike and runner can always be engaged if the strike can be engaged with the runner even if the drawer is lowered. .

  The first invention of the present invention is composed of a retracting device and a strike for operating the retracting device, and the runner of the retracting device is always pulled backward by a tension spring, and the strike is retracted when the drawer is opened. The runner is moved to the standby position by engaging with the first locking piece formed on the runner of the apparatus, and when the drawer is closed, the strike is engaged with the first locking piece and pulled back by the tension spring. In the pull-in mechanism for the drawer, the strike engaging portion is movable in a direction orthogonal to the portion to which the strike is attached.

  The second invention of the present invention is composed of a retracting device and a strike for operating the retracting device, and the runner of the retracting device is always pulled inward by a tension spring, and when the drawer is opened, the strike is retracted. The runner is moved to the standby position by engaging with the first locking piece formed on the runner of the apparatus, and when the drawer is closed, the strike is engaged with the first locking piece and pulled back by the tension spring. In the pull-in mechanism of the drawer that sets the non-standby position, the strike engaging portion is movable in a direction perpendicular to the portion to which the strike is attached, and the strike is movable in the vertical direction. This is a drawing-out mechanism of the drawer.

  According to the first invention of the present invention, when the side wall of the furniture swells outward after many years after the manufacture of the furniture, the strike is always in a position where it can engage with the runner. The present invention has an excellent effect that the conventional retracting mechanism that can be properly engaged and completely fulfill the role of the retracting device can be obtained.

  In addition, according to the second invention of the present invention, even after many years have passed since the furniture was manufactured, even if the drawer of the furniture drops downward, the strike moves in the vertical direction, so the runner and the strike are always properly engaged. Thus, an excellent effect that the conventional retracting mechanism can completely fulfill the role of the retracting device is achieved.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  The strike of the first embodiment used in the present invention is shown in FIGS. 1 to 12, and FIGS. 1 to 10 are suitable for mounting on a wooden drawer. The strike 60 is made of resin, and a lower portion is an attachment portion 61 and an upper portion is an engagement portion 62.

  The attachment portion 61 is formed with rectangular spring holes 63 and 64 at symmetrical positions on the front surface, and pressing springs 65 and 66 are integrally formed with the attachment portion 61 in the spring hole. As shown in FIGS. 5 to 7, the pressing spring 65 in the spring hole 63 has a shape curved downward from the upper part of the spring hole 63 and rearward, and slightly protrudes from the back surface of the mounting portion 61. . The pressing spring 66 in the spring hole 64 has a shape that is curved upward and downward from the lower part of the spring hole 64 and slightly protrudes from the back surface of the mounting portion 61.

  When the strike 60 is attached to the side plate of the drawer, the protruding portions of the pressing springs 65 and 66 abut against the side plate of the drawer, and the spring force repels the entire strike, that is, the strike engaging portion, from the side plate. It is designed to push in the orthogonal direction.

  The pair of pressing springs 65 and 66 are formed in opposite directions in the vertical direction, and each pressing spring presses the side plate of the drawer from the vertical position, so that the strike is pressed evenly and does not tilt.

  Further, screw holes 67 and 67 are formed in the mounting portion 61 outside the pair of spring holes 63 and 64. The screw hole is vertically long in the vertical direction, the lower end is a semicircular shape, and the upper end is a semirectangular shape. Screw springs 68, 68 are integrally formed with the mounting portion 61 at the upper portions of the screw holes 67, 67. As shown in FIG. 2, these screw springs protrude obliquely downward from the upper corners of the screw holes 67 and 67 and are bent horizontally. The space between the semicircular lower part of the screw hole 67 and the lower surface of the screw spring 68 is substantially the same as the diameter of a holding portion of a later-described wood screw screw to which a strike is attached. Therefore, after the wood screw screw is inserted into the screw hole and the strike is attached to the side plate of the drawer, the wood screw screw is in contact with the lower surface of the screw spring 68 and the semicircular lower portion of the screw hole 67 at normal times. When a pressure is applied to the strike from above, the strike descends against the spring force of the screw spring and leaves the lower surface of the semicircular shape. Thereafter, when the pressure from above is lost, the spring force of the screw spring returns to the original position, that is, the position in contact with the lower surface of the screw spring 68 and the lower half of the screw hole 67. The screw holes 67, 67 are formed with a recess 69 that allows the screw head of the wood screw screw to sink when the wood screw screw is inserted.

  The engagement portion 62 of the strike 60 is formed with a main engagement step portion 70 and a temporary engagement step portion 71 at symmetrical positions. The main engagement step portion and the temporary engagement step portion are formed on the left and right sides in this manner because they can be formed on either side when the strike is attached to the left and right of the drawer. Since the shapes and functions of the main engaging step and the temporary engaging step have already been described, their description is omitted here.

  Protruding shapes 72 and 72 are formed on the upper portion of the engaging portion 62 in two places. The copying protrusion has a rounded upper end so that it smoothly slides against an object in contact therewith.

  Here, the mounting state and the movement of the strike in the strike of the first embodiment used in the present invention will be described with reference to FIGS.

  The wood screw screw 73 for attaching the strike to the drawer side plate has a screw head 74 and a wood screw portion 75 as shown in FIG. 9, and the screw head 74 is sized so as to be easily immersed in the insertion hole of the screw hole. . A cylindrical body 76 is inserted into the wood screw portion 75. The cylindrical body is longer than the dimension from the depression 69 to the back surface of the mounting portion 61 by a distance d.

  When attaching the strike to the drawer, if the predetermined position is determined with respect to the runner of the retractor, apply the strike to the side plate of the wooden drawer and insert a drilling tool such as a cone or a drill into the screw hole to open the pilot hole. I can make it. Thereafter, a wood screw screw is inserted into the screw hole, and the wood screw portion is screwed into the lower hole with a screwdriver. When the end of the cylindrical body 76 into which the wood screw portion 75 is inserted comes into contact with the side plate 24 of the drawer, the wood screw portion is inserted. The screwing of the screw part 75 is stopped. Then, the strike 60 is repelled by the pressing springs 65 and 66 coming into contact with the side plate, and the entire strike is pushed in a direction perpendicular to the side plate (left side in FIG. 10). At this time, a separation distance d is generated between the back surface of the strike and the side plate. However, since the strike is only separated from the side plate by the pressing spring, when the pressure from the direction orthogonal to the strike 60 is applied, the strike can move in the direction of the side plate 24 by a distance d.

  The distance d between the strike back surface and the side plate is practically about 0.1 to 1 mm. That is, since the bulge of the side wall of the furniture that has passed many years after manufacture is at most 1 mm on one side, the movement of the engaging portion of the strike may be at most 1 mm.

  Here, the operation of the retracting mechanism in the furniture to which the above embodiment is attached will be described.

  When the retracting device is attached to the side plate of the furniture as shown in FIG. 23, the strike is attached to the side plate of the drawer with wood screw screws. At this time, as shown in FIG. 21, the runner 32 of the retracting device 30 is in the innermost position, that is, in the non-standby position, and the main engagement step portion 70 of the strike 60 is moved to the first locking piece 39 of the runner 32. The strike 60 is attached to the side plate of the drawer so as to be engaged with each other. After the strike is attached, as shown in FIG. 10, the strike is maximally separated (d) from the side plate of the drawer, so that the engaging portion 62 contacts the first locking piece 39 and the second locking piece 40. It becomes a state. However, even if the strike 60 comes into contact with these locking pieces, the engaging portion 62 is pushed in a direction orthogonal to the drawer side plate by a pressing spring, so that the locking piece or the strike is damaged or pulled out. Engage reliably with the runner without interfering with running.

  In the strike in the first embodiment, a screw spring is formed in a vertically long screw hole. When a force is applied to the strike from above, the strike moves downward as much as the screw spring moves upward. Therefore, when the strike is attached to the drawer, the protrusions 72 and 72 are in contact with the lower surface of the drawing device 30 as shown in FIGS. 21 and 22, and the screw spring is moved slightly upward. That is, when the drawer is closed, the striking protuberance comes into contact with the lower surface of the retracting device, the strike moves downward against the screw spring, and when the drawer is opened, it does not contact the retracting device. That is, the strike moves upward by the screw spring when the force from above is not applied. Then, after many years, when the drawer is slightly lowered downward, the strike and the runner continue to be properly engaged even if the striking projection does not contact the lower surface of the retracting device. This strike can be attached with a margin in the vertical direction during attachment.

  The above embodiment is a strike suitable for a wooden drawer, and is difficult to attach to a metal drawer. A strike suitable for mounting on a metal drawer will be described with reference to FIGS. FIG. 11 is a front view thereof, and FIG. 12 is a cross-sectional view taken along line EE of FIG.

  The structure of the attachment portion 61 and the engagement portion 62 of the strike 60 is the same as the strike attached to the wooden drawer, but the strike is not attached directly to the drawer but is attached via an attachment fitting.

  The above-mentioned strike for wooden drawer is done by inserting a wood screw screw into the screw hole and screwing the wood screw part of the wood screw screw into the side plate of the wooden drawer. The screw part cannot be screwed in. Therefore, when attaching a strike to a metal drawer, a mounting bracket is used.

  The mounting bracket 78 is made of metal and has a plate-like shape having an L-shaped cross section whose lateral width is substantially the same as the lateral width of the strike 60. A vertical portion of the mounting bracket 78 is a strike mounting surface 79 and a bottom portion is a drawer mounting surface 80. On the strike mounting surface 79, a rising portion 81 is formed at a position coinciding with the screw holes 67, 67 of the strike 60, and a female screw is screwed inside the rising portion. The height of the rising portion 81 is the same as the separation distance d of the wooden drawer strike. The drawer mounting surface 80 has a plurality of drawer mounting holes 83... (Two or more).

  The straight screw 84 that attaches the strike to the metal drawer side plate has a screw head 85 and a straight screw portion 86 as shown in FIG. The screw head 85 is sized to be immersed in the insertion hole of the screw hole 67. A cylindrical body 87 is inserted into the straight screw portion 86. The cylindrical body has the same height as the dimension from the depression 88 to the back surface of the mounting portion 61. Accordingly, when the straight thread screw 84 is inserted into the screw hole 67 and the straight thread portion 86 is screwed into the female screw of the cylindrical body 87, the end portion of the cylindrical body 87 abuts on the rising portion 81 and is screwed. Stop. Then, the pressing springs 65 and 66 are in contact with the strike mounting surface 79 and push the strike 60 in a direction orthogonal to the left (left side in FIG. 12), so that the entire strike, that is, the engaging portion 62 is separated from the strike mounting surface 79 by a distance d. To do.

  Here, a state where the strike is attached to the metal drawer will be described. First, the strike 60 is attached to the strike attachment surface 79 of the attachment metal 78 with the straight screw screw 84. Then, place the mounting bracket in a place that is appropriate for the pull-in device attached to the side wall of the furniture, drill a hole in the bottom plate of the drawer that coincides with the drawer mounting hole 83, and screw in the hole in the drawer mounting hole and the bottom plate. Insert and fix.

  Even if it is difficult to attach the strike to the metal drawer, the strike can be easily and firmly attached by using the mounting bracket.

  Next, the strike of the second embodiment used in the drawer attachment mechanism of the present invention will be described. 13 is a perspective view of a strike used in the second embodiment, FIG. 14 is an exploded perspective view thereof, FIG. 15 is a cross-sectional perspective view taken along line FF in FIG. 13, and FIG. 16 is a cross-sectional view taken along line FF in FIG. FIG. 17 is a side view of the strike of the second embodiment in which the attachment portion and the engagement portion are separated from each other to the maximum, and FIG. 18 is a side view of the strike of the second embodiment in which the attachment portion and the engagement portion are closest.

  The strike 90 used in the second embodiment is composed of two members, a mounting portion 91 and an engaging portion 92.

The engaging portion 92 of the strike 90 is a forming portion 93 having a U-shaped cross section and one end rising upward. A conical rivet hole 94 is formed in the center of the front surface protruding forward of the engaging portion 92, and vertically long screw holes 95, 95 are formed on both sides thereof. The formation portion 93 is formed with main engagement step portions 70 and 70 and temporary engagement step portions 71 and 71. Inwardly projecting flanges 96, 96 are formed on the upper and lower portions of the engagement portion 92 on the back surface of the recessed portion.

  The attachment portion 91 of the strike 90 has a convex cross section, and the front portion with a wide vertical width is a sliding portion 97 and the rear portion with a narrow vertical width is a fixed portion 98. The vertical width of the sliding portion 97 is slightly smaller than the inner vertical dimension of the U-shape of the engaging portion 92, and the depth dimension of the sliding portion 97 is the inner side of the U-shape of the engaging portion 92 as shown in FIG. It is smaller than the depth dimension by d. Therefore, the engaging portion 92 can move by a distance d in a direction orthogonal to the attachment portion 91, and can move in an unlimited amount laterally before inserting a rivet described later.

  The attachment portion 91 is formed with a rivet stop hole 99 projecting from a spring groove, which will be described later, at a position coincident with the rivet hole 94 of the engagement portion 92, and coincides with the screw holes 95, 95 of the engagement portion 92. The screw insertion holes 100 and 100 having the same shape as the screw holes are formed in the first and second holes. In addition, spring grooves 101 and 101 are engraved inside the screw insertion holes 100 and 100 on both sides of the rivet stop hole 99, and the pressing springs 102 and 102 are mounted in a state where the springs 102 and 102 are raised upward from the spring groove. It is integrally formed with the part 91. As shown in FIGS. 15 and 16, the pressing spring has a Y-shaped cross section, and its upper end is bent laterally and protrudes upward from the spring groove 101.

  The engagement portion 92 and the attachment portion 91 are fixed with rivets. As shown in FIG. 14, the rivet 103 has an inverted conical head 105 formed at one end of the cylindrical portion 104. The cylindrical portion 104 has a diameter slightly smaller than the diameter of the bottom portion of the rivet hole 94, and the head portion 105 has a shape slightly smaller than the conical rivet hole 94.

  When assembling the engaging portion 92 and the attaching portion 91, the sliding portion 97 of the attaching portion 91 is inserted into the U-shaped portion of the engaging portion 92, and the rivet hole 94 of the engaging portion 92 and the rivet stop hole 99 of the attaching portion 91 are inserted. Stop insertion when matches. At this time, the engaging portion 92 is pressed against the back surface by the pressing spring 102, and therefore is separated from the mounting portion 91 by a distance d as shown in FIG. Thereafter, the rivet 103 is inserted from the rivet hole 94 into the rivet stop hole 99, and the tip of the rivet is crushed on the back surface of the mounting portion 91. Then, the engagement portion 92 and the attachment portion 91 do not move laterally, and move by d when a force from the orthogonal direction (arrow X in FIG. 18) is applied. When attaching the strike to the wooden drawer, a wood screw is inserted into the screw hole 95 and the screw insertion hole 100, and the wood screw is screwed in and fixed with a screwdriver.

  After the strike used in the second embodiment of the present invention is attached to the side plate of the drawer, if no force is applied in the direction orthogonal to the side plate, the engaging portion 92 is maximized by d from the side plate 24 as shown in FIG. It is separated. However, when a force is applied to the strike engaging portion 92 (arrow X in FIG. 18) when the drawer is closed, the drawer moves toward the side plate 24 and comes closest.

  The strike used in the second embodiment of the present invention moves in a direction perpendicular to the side plate, but does not move up and down. However, when adjusting the mounting position in the vertical direction, the wood screw inserted from the screw insertion hole 100 and screwed into the side plate of the wooden drawer is loosened and moved within the vertical range of the vertically long screw insertion hole. .

  Further, the strike of the third embodiment used in the drawer retracting mechanism of the present invention will be described with reference to FIGS. FIG. 19 is an exploded perspective view thereof, and FIG. 20 is a plan view thereof.

  The strike 110 used in the third embodiment is composed of two members, an attachment portion 111 and an engagement portion 112, as in the second embodiment. The engaging portion 112 has the same shape as the engaging portion 92 of the second embodiment, but the pressing spring and the spring groove are different. Therefore, the strike used in the third embodiment will be described with respect to the pressing spring and the spring groove, and the other parts will be assigned the same reference numerals as in the second embodiment, and the description thereof will be omitted.

  As shown in FIG. 19, the strike spring groove 113 used in the third embodiment is engraved in a horizontally long rectangular shape with the rivet stop hole 99 as the center. The pressing spring 114 is a metal leaf spring whose length in the vertical direction can be easily inserted into the spring groove 113, and a hole 115 through which the protruding rivet stop hole 99 can be inserted is formed in the center. It is installed. The pressing spring 114 has a bottom 116 around the hole 115, and both sides of the pressing spring 114 rise obliquely upward, and the portions exiting the spring groove 113 are pressing surfaces 117 and 117 bent in the horizontal direction.

  The strike used in the third embodiment maintains a separation distance by d as shown in FIG. 20 when no force is applied in the side plate direction. Since the action of the strike in the third embodiment is the same as in the second embodiment, the description thereof is omitted.

The present invention can be applied to anything that has a drawer, for example, a cabinet, kitchen furniture, a desk, a sorting cabinet, and the like.
In the embodiment, the retracting device is attached to the side wall of the furniture and the strike is attached to the side plate of the drawer, but conversely, the retracting device can be attached to the side plate of the drawer and the strike can be attached to the side wall of the furniture.
In the embodiment, the strike is shown as having a main engagement step portion and a temporary engagement step portion, but it goes without saying that the strike can be applied to any shape as long as it engages the runner of the retracting device.
