Description

  The present invention relates to a drawer provided with a latch device that is released by a handle.

  The drawer latch device basically has a pull handle that is operated by a person, a latch claw that engages with an engagement portion provided on the inner side of the furniture body, and an interlock that makes the latch claw free by the movement of the pull handle. Member.

  In general, the pulling handle is of a rotating type, and only one pulling hole is provided in the front plate of the drawer main body. However, Patent Document 1 discloses the left and right side surfaces of the hollow end plate portion. It is disclosed that a vertically long handle is arranged along the line. In Patent Document 1, a horizontally long interlocking member is disposed at the upper part of the end plate part, and when the left or right puller is pulled, the interlocking member rotates about its axis. In addition, a downward arm is bent at the end of the interlocking member, while a lateral arm is bent at the latch pawl support shaft. The arm is rotated so that the latch claw is detached from the furniture body.

JP 2006-291573 A

  By the way, drawers are provided on desks, wagons, and kibbinets, but if they are installed on desks or in loose cabinets or wagons that are used together with desks, drawers are inevitably pulled out. Is located to the right or left of the user.

  And, if the handle is only arranged on the left and right sides of the drawer, the user must extend the hand to the right or left handle and perform the pulling operation of the drawer. Since it is normal that the opposite side of the handle is out of reach, the puller on the side close to the user will be pulled, but for that purpose it is unnatural to twist the hand and point the palm toward the back Because of this, it can be said that some people find it difficult to use.

  Moreover, although the interlocking member of patent document 1 is manufactured by the bending process and the welding process by using a wire and a plate as a material, in this structure, since a processing error is easy to occur in a bending process or a welding process, There is also a risk that variations in the accuracy of transmitting the movement to the latching claw are likely to occur.

  The present invention has been made to improve such a situation, and an object of the present invention is to provide a drawer having a latch device excellent in operability.

  In order to achieve the above object, the present inventor has made the invention of each claim 1. Among these, the drawer according to the invention of claim 1 has a storage box and a hollow end plate portion provided at the front end thereof, and a finger hook portion of a side puller on the left side or the right side or both left and right sides of the end plate portion. The upper hook is provided with a finger hook portion on the upper side, and a latch claw is provided on the left side or right side of the end plate portion or on the rear side of both left and right sides. Interlocking means for disengaging the latch pawl regardless of which is operated is provided.

  In this configuration, “to make the latch claw disengaged” means that the latch claw is released from the engaging portion of the furniture body as in Patent Document 1 and can be detached as in the present embodiment. In this state, the latch pawl is disengaged from the engaging portion by the forward movement of the drawer.

  According to a second aspect of the present invention, in the first aspect of the present invention, the left and right laterally long first interlocking member that rotates into the operating posture regardless of whether the side puller or the upper puller is operated, A second interlocking member is provided for bringing the latch pawl into a disengaged state in conjunction with the rotation of the first interlocking member to the operating posture.

  According to a third aspect of the present invention, in the first or second aspect, the side puller is a horizontal rotation type, while the upper puller and the first interlocking member are rotated around a parallel axis that is horizontally long. And pressing the first interlocking member at a portion of the upper puller that is located on the opposite side of the finger-holding portion across the rotational axis, thereby rotating the first interlocking member to the operating posture, and the side puller Of these, the first interlocking member is rotated to the operating posture by pressing the first interlocking member at a portion on the opposite side of the finger-hanging portion with the rotation axis interposed therebetween. According to a fourth aspect of the present invention, the upper puller and the side puller are molded products made of metal or resin.

  Since the drawer of the present invention has an upper puller and a side puller, the user only has to pull a finger on a handle that is easy to handle according to its position, posture, and the like, which is convenient. Furthermore, for example, when applied to desk sleeve drawers, sleeve cabinets or sleeve wagons, the user may hang his fingers on the upper puller in a natural state with the palm facing down without twisting the arm. This makes it easy to pull out the drawer. In addition, when the user is positioned in the front direction of the drawer, the user can place a finger in a natural state on either the side puller or the upper puller.

  And since the movement of the upper puller and the side puller is transmitted to the common interlocking means and the latch claw is disengaged, there is no need to separately provide the interlocking means for the upper puller and the interlocking means for the side puller. Therefore, the structure can be simplified accordingly.

  Although it can be said that it is not impossible to configure the interlocking means with a single interlocking member, in this case, the structure of the interlocking member becomes complicated and the design becomes troublesome, and the movement becomes complicated and the certainty of the operation is improved. There is a risk of damage. On the other hand, if the interlocking means is composed of the first interlocking member and the second interlocking member as in claim 2 of the present application, the design is easy because the roles of the first interlocking member and the second interlocking member are separated. In addition, since the movement of each interlocking member can be simplified, the reliability of the operation can be ensured. In addition, since there are only two types of interlocking members, the structure is simple and can be arranged inside the end plate without any trouble.

  If the structure of Claim 3 is employ | adopted, since the 1st interlocking member is horizontal right and left, it can respond by changing the length of a 1st interlocking member with respect to the difference in the horizontal width of a drawer, and the 2nd interlocking member differs in horizontal width. Therefore, the cost can be suppressed when assembling a plurality of types of drawers having different widths.

  Further, although the pull handle can be a push type, in this case, the push direction of the pull and the pull direction of the drawer are different, so that the smoothness of the operation is lacking. When the upper puller and the side puller are configured to be pivotable, the operation direction of the puller and the pulling direction of the drawer are the same, so that the operability is excellent. Furthermore, since the upper puller and the side puller are parallel to each other in the third aspect, the movement of the upper puller can be accurately transmitted to the first interlocking member.

  When the molded product is employed for the upper puller and the side puller as in the fourth aspect, high dimensional accuracy and rigidity can be ensured, so that the certainty of movement and the smoothness can be improved. In particular, the width of the drawer is the length of the kana and the length of the upper handle becomes longer, but by using a molded product such as an extruded product, it moves with a straightness even if it is a long length. There is an advantage that can be made smooth.

  It should be noted that providing an upper puller on at least the upper surface of the end plate part and making at least one of the upper puller and the side puller into a molded product such as an extruded product may be an independent invention by itself. obtain. Further, the first interlocking member of the embodiment can be a molded product such as an extruded product, and this can also be an independent invention.

  Next, an embodiment of the present invention will be described with reference to the drawings. The present embodiment is applied to a wagon drawer as an example of furniture. In the following description, the words “front and rear” and “left and right” are used to specify the direction, and this is based on the state of the wagon as viewed from the front as shown in FIG.

(1). Outline of drawer The wagon of this embodiment can be placed inside a desk, for example, and as shown in FIG. The upper drawer 2 has the smallest height and the lower drawer 2 "has the height dimension. The three drawers 2, 2 'and 2" are provided. The middle drawer 2 'has an intermediate height between the two, and a cylinder lock 6 is provided on the right side of the upper drawer 2 so that the inner cylinder 6a having a key hole is exposed to the front. A dial lock 6 'is attached to the drawer 2' in the middle stage.

  Each drawer 2 is supported by a suspension rail device (not shown) on an inner plate constituting the wagon body 2 so as to be movable back and forth. Needless to say, the wagon and the drawers 2, 2 ', 2 "are rectangular in front view. First, the drawer will be described. Here, the drawer 2 in the upper stage will be described.

  For example, as shown in FIGS. 2 and 3, the drawer 2 includes a storage box 3 having a bottom plate 3a, left and right side plates 3b, and a back plate (not shown), a front plate (end plate) 4 and a back plate provided at the front end thereof. 5 as main members, and these three members constitute a drawer body. A rail member 7 is attached to the outer surface of the side plate 3 b in the storage box 3. The storage box 3 and the front plate 4 are made of steel, but the back plate 5 is a resin molded product. Of course, the back plate 5 can be made of steel, and the front plate 4 can be made of resin.

  For example, as can be understood from FIG. 5 (B), the front plate 4 has wall plates 4a, 4b, 4c on four sides and is formed in a shallow box shape opened rearward, for example, as shown in FIG. In addition, the back plate 5 is also formed in a shallow box shape with a forward opening having wall plates 5a, 5b and 5c around the four sides, and both are fitted so as not to be detached. The front plate 4 and the back plate 5 constitute a hollow end plate portion K, and a base 8 that is square in front view is disposed inside the end plate portion K.

  The base 8 is formed in a shallow tray shape having walls 8a, 8b, and 8c around the four sides, and is disposed inside the back plate 5 in a state of opening forward. For example, as shown in FIG. 8, left and right side pullers 9 that can be pulled by applying a finger to the base 8 from the left and right side portions of the front plate 4, and a pulling operation by applying a finger from the upper portion of the front plate 4. The upper puller 10 that can be engaged, the latch claw 11 that engages with the wagon body 1, and the first interlocking member 12 and the second interlocking member 13 that make the latch pawl 11 free by pulling one of the pullers 9 and 10 are attached. ing.

  The latch device is configured with these pulls 9 and 10, the latch claw 11 and the interlocking members 12 and 13 as elements. The latch claw 11 is attached to the left side portion of the base 8. The middle and lower drawers 2 'and 2 "are provided with only the side puller 9, and the upper puller 10 is not provided.

  The second interlocking member 13 functions as a stopper that keeps the latch claw 11 engaged with the wagon body 1, and the stopper function of the second interlocking member 13 is released by the movement of the first interlocking member 12. . Therefore, in this embodiment, the 2nd interlocking member 13 can also be called a stopper, and the 1st interlocking member 12 can also be called a relay member.

(2). Drawer body Next, each part will be described in detail. First, the structure of the drawer body will be described. For example, as shown in FIG. 1 (B), the left and right side walls 5b of the back plate 5 have a stepped portion 5d that is displaced inward, and the front portion of the storage box 3 is located from the rear at this stepped portion 5d. It is fitted. The storage box 3 is held so as not to be detached from the back plate 5.

  Further, as clearly shown in FIG. 12, an upright standing piece 5e is provided at the front end of the upper wall 5a of the back plate 5, while the upper portion of the front plate 4 is hollow by providing a hanging piece 4d on the upper wall 4a. The upright piece 5e of the back plate 5 is fitted into the inside thereof. Therefore, the outer peripheral surface of the end plate portion K has two stages, that is, a high step portion constituted by the outer peripheral surface of the front plate 4 and a low step portion constituted by the outer peripheral surface of the back plate 5. Is exposed to the outside from the lower step portion constituted by the outer peripheral surface of the back plate 5.

  The lower wall 5 c of the back plate 5 is in contact with the back surface of the front plate 4. For example, as shown in FIG. 1B, a relief hole 14 for allowing the upper handle 10 to be attached is opened in the upper wall 5a of the back plate 5. The escape holes 14 are arranged on both the left and right sides of the center line, and are left and right horizontally elongated square holes.

  As shown in FIG. 1 (B) and FIG. 2 (B), a side relief hole with a forward opening is provided to allow attachment and movement of the side puller 9 to the side wall 5b at the outer end of the stepped portion 5d in the back plate 5. 15 is formed. The side relief holes 15 are long in the vertical direction.

  Further, as shown in FIG. 1B, the first window hole through which the flange 50 of the cylinder lock 21 passes through the right step wall 5b 'connecting the rear surface of the back plate 5 and the right stepped portion 5d. 16a is formed, and a second window hole 16b is formed in the stepped portion 5d. The window holes 16a and 16b are provided with a lock guide 17 for slidably holding a lock collar 50. On the other hand, as shown in FIGS. 4C and 4D, an escape hole 18 communicating with the stepped portion 5d and the stepped wall 5b ′ is formed on the left side of the back plate 5. The latch claw 11 is exposed.

  As shown in FIGS. 5 and 7, the base 8 of this embodiment is composed of two members, a left member 8 ′ and a right member 8 ″, and a latch claw 11 is attached to the left member 8 ′. The right side portion 8d 'of the left member 8' and the left side portion 8d "of the right member 8" overlap with each other. That is, the left side portion 8d "of the right member 8" and the right side portion 8d of the left member 8 '. The right member 8 ″ is provided with a pair of left and right positioning pins 8e ′ on the upper surface of the left side portion 8d ″, while the right side portion 8d ′ of the left member 8 ′ has a positioning pin 8e. A positioning hole 8e "into which 'is fitted is provided.

  As can be understood from FIG. 3, the right side portion 8d 'of the left member 8' and the left side portion 8d "of the right member 8" also overlap with the bottom walls 8c ', 8c ". A longitudinally extending ridge (not shown) projects downward from the bottom wall 5c 'of the member 8', and a groove 8f into which the ridge is fitted is formed on the bottom wall 8c "of the left side 8d '. .

  Inner protrusions 19a and outer protrusions 19b are projected on the upper surfaces of the left member 8 'and the right member 8' 'constituting the base 8. These protrusions 19a, 19b are provided on the upper wall 5a of the back plate 5. The base 8 is firmly held by the back plate 5 by the fitting of the projections 19a, 19b and the holes 20a, 20b, and the outer projection 19b is fitted to the back plate 5. 12, the upper drawer 2 is set in contact with or in close contact with a stopper plate 21a provided on the lower surface of the upper gusset 21 in the wagon body 1. As shown in FIG. It is held in a state where it does not rattle up and down while being pushed into the main body 1.

  In addition, as shown with a dashed-dotted line in FIG. 12, the raising / lowering top plate 1a can be attached to the wagon main body 1. FIG. Needless to say, even when the liftable top plate 1a is attached, a space for a person to put his / her finger on the upper handle 10 is vacant above the upper handle 10.

(3) .Latch device (latch claw / second interlocking member)
Next, the latch device will be described. First, the latch claw 11 will be described mainly with reference to FIGS. For example, as clearly shown in FIG. 9C, the latch claw 11 has a base portion 23 extending in the left-right direction, and a L-shaped claw portion 24 that protrudes backward from the left outer end portion of the base portion 23. It is arranged outside the left side wall 8a of the base 8.

  As shown in FIG. 11, the engaging surface (front surface) 24a of the claw portion 24 of the latch claw 11 is in a posture extending in the left-right direction. On the other hand, the rear surface of the engagement surface 24a is an inclined surface 24b that shifts backward as it approaches the base 23 side.

  For example, as shown in FIG. 15, the latch claw 11 is attached to a holder portion 26 provided integrally with the left side portion of the base 8. The holder portion 26 is configured to surround the latch claw 11 from above and below and from the inside, and the latch claw 11 is connected to a portion of the holder portion 26 that protrudes outside the base 8 by a vertically long pin 27. The pin 27 is integrally formed with the latch claw 11. As shown in FIG. 14, the pin hole of the holder portion 26 is a left and right elongated slot 28, so that the latch claw 11 can slide to the left and right without changing its posture, and can be rotated horizontally around the pin 27. Can move.

  As shown in FIG. 15, a U-shaped holding member 29 in a front view is fitted into the claw portion 23 of the latch claw 11 from the inside, and between the holding member 29 and the left side wall 8 b of the base 8. A spring 30 (see FIG. 11) is arranged. Therefore, the latch claw 11 is urged to the left outer side by the spring 30. The holding member 29 is made of a resin having a small coefficient of friction and high durability (for example, POM resin or nylon resin), and therefore can also be called a slider.

  As shown in FIG. 11, the front part of the side part of the wagon body 1 is hollow by fixing a reinforcing frame 32 to the side plate 31, and the latch claw is in a state where the drawer 2 is fully pushed into the reinforcing frame 32. An engaging hole 33 is provided in which the 11 claw portions 24 are fitted and engaged. The latch claw 11 is set so that the stopper portion 25 is in contact with or close to the bottom surface of the base 8 in the engagement posture in which the tip of the claw portion 24 is fitted in the engagement hole 33. Therefore, the latch claw 11 can rotate in the clockwise direction (the disengagement direction in which the claw portion 24 is detached from the engagement hole 33) in the state of FIG. 13, but cannot rotate in the counterclockwise direction.

  As shown in FIGS. 14 and 15, an upward guide pin 70 projects from the base end portion of the latch claw 11, while the guide pin 70 fits on the upper surface plate of the holder portion 26 provided on the base 8. A groove 71 is formed to accurately guide the movement of the latch claw 11.

  The guide groove 71 includes a slide guide portion 71a that is parallel to the long hole 28 provided in the holder portion 26, and an arcuate rotation guide portion that guides the latch pawl 11 from rotating horizontally from the fully engaged position. 71b, and both communicate with each other. By the guide action of the guide pin 70 by the guide groove 35, the latch claw 11 only rotates when the drawer 2 moves forward, and when it is pushed in, it slides and kicks smoothly.

  For example, as shown in FIG. 15, a boss-like support shaft 36 is integrally provided on the right side of the holder portion 26 in the bottom surface of the base 8, and the second interlocking member 13 is rotatably attached to the support shaft 36. . The second interlocking member 13 includes a cylindrical portion 13a that fits on the support shaft 36, a substantially horizontal posture stopper portion 13b that extends behind the base portion 23 of the latch claw 11, and a passive portion 13c that is located on the opposite side of the stopper portion 13b. And is supported by the support shaft 36 so as to be able to rotate around an axis extending in the front-rear direction.

  As shown in FIG. 15, a base end portion of the cylindrical portion 13 a in the second interlocking member 13 is provided with a pair of protrusions 13 d that protrude in a direction orthogonal to the stopper portion 13 b and the passive portion 13 c, while the base 8 A pair of holding pieces 36a surrounding the protrusion 13d of the second interlocking member 13 is provided at the bottom, and the second interlocking member 13 is held so as not to be detached from the support shaft 36. The second interlocking member 13 is attached by a procedure of fitting into the support shaft 36 in a state where the protrusion 13d is rotated so as not to hit the holding piece 36a, and then rotating back to a predetermined posture. For example, as shown in FIG. 8, a downward portion 26 a for preventing the second interlocking member 13 from coming off is also provided in the holder portion 26 that holds the latch claw 11.

  As shown in FIG. 9C, when the stopper portion 13b of the second interlocking member 13 is positioned behind the base portion of the latch claw 11, the latch claw 11 is in an engagement maintaining state in which horizontal rotation is impossible. On the other hand, when the second interlocking member 13 is in a free posture in which the stopper portion 13b is moved downward, the latch claw 11 is also in a free state in which the latch claw 11 can rotate in the disengagement direction. As shown in FIG. 9C, the flange 23a provided at the end of the base 23 constituting the latch claw 11 and the flange 13e provided at the tip of the stopper 13b of the second interlocking member 13 are engaged with each other. Is set. Therefore, the forward movement position of the latch claw 11 in the engagement maintaining posture is restricted.

(4) .Latch device (first interlocking member, puller)
For example, as can be understood from FIGS. 9A and 9B, the first interlocking member 12 is a sheet metal processed product and extends long in the left-right direction. As clearly shown in FIG. , A backward-facing U-shaped passive portion 12b provided at the upper end of the base portion 12a, and a flat plate-like drive portion 12c protruding forward from the lower end of the base portion 12a. The left end of the drive unit 12c overlaps the passive unit 13c of the second interlocking member 13 from below (see, for example, FIG. 8C).

  As the shaft support structure of the first interlocking member 12, a resin support shaft (boss body) 37 is used. That is, as shown in FIG. 7, notches 12d are formed at both left and right ends of the base portion 12a of the first interlocking member 12, and the support shaft 37 is fitted into the notch 12d. A first bearing piece 38 into which the support shaft 37 is fitted is formed. A portion of the support shaft 37 that fits into the notch 12 d is bifurcated so as to sandwich the first interlocking member 12. The head of the support shaft 37 is rounded.

  The first bearing piece 38 has a circular hole that is not a slitting method, and the support shaft 37 is pushed into the first bearing piece 38 against its elasticity. On the opposing surfaces of the two first bearing pieces 38, inclined surfaces for guiding the support shaft 37 are formed.

  For example, as shown in FIG. 6 (A), the upper handle 10 has a finger-hanging portion 10a and a pair of left and right foot portions 10b protruding downward from the finger-hanging portion 10a. A pair of left and right support shafts 41 are attached to the height portion, and the support shaft 41 is fitted into a pair of left and right second bearing pieces 39 and 40 provided on the base 8. The lower end of the foot portion 10b is in contact with or in close contact with the passive portion 12b of the first interlocking member 12 from the front.

  The support shaft 41 provided in the upper handle 10 has the same structure as that used for the first interlocking member 12, and this support shaft 41 is formed in a notch 41a provided in the side surface portion of the foot portion 10b. Also, the pair of second bearing pieces 39 and 40 into which the support shaft 41 is fitted is located on the inner side, and has a bearing hole that opens upward and has a constricted opening. The bearing piece 40 has a circular bearing hole that is not cut.

  The support shaft 41 provided in the upper puller 10 is fitted and mounted on the second bearing pieces 39 and 40 by being pushed in from above, whereby the upper puller 10 rotates about a long axis in the left-right direction. In this case, the inner second bearing piece 39 is opened upward to facilitate positioning (induction). Further, the support shaft 41 is forcibly fitted into the bearing pieces 39, 40, but the surface of the second bearing piece 40 that contacts the support shaft 41 is formed as an inclined surface that escapes outward, and the tip end of the support shaft 41 is formed. The hemispherical shape facilitates fitting of the support shaft 41.

  The upper handle 10 is attached in the last step of assembling the drawer 2. That is, after the steps of attaching the base 8 to the back plate 5 and connecting the storage box 3 to the back plate 5 and the front plate 4, the foot 10b is inserted into the escape hole 14 and the second bearing pieces 39, 40 are inserted. It is performed by the procedure of fitting in.

  As clearly shown in FIG. 12, the finger hooking portion 10 a of the upper puller 10 is located on the back side of the drooping piece 4 d provided on the upper wall 4 a of the front plate 4 (that is, the upper puller 10 is an upper portion of the front plate 4. Is located on the back side.) Further, a forward rib 10c is formed at the lower end portion of the finger hooking portion 10a of the upper puller 10 so as to extend over the entire length of the left and right, and by applying the forward rib 10c to the upper wall 5a of the back plate 5, the upper puller 10 The forward rotation angle can be restricted. That is, the forward rib 10c can function as a rotation restricting stopper.

  As described above, the upper wall 5a of the back plate 5 has an upper upper relief hole 14 into which the foot portion 10b of the upper puller 10 is fitted. There is a risk of touching and damaging the aesthetics. With respect to this point, in the present embodiment, a forward rib 10c is provided on the finger hooking portion 10a of the upper puller 10, and the upper upper relief hole 14 is covered with the forward rib 10c. For this reason, deterioration of aesthetics can be prevented. A backward-facing rib 10d is provided at the base end of the finger rest 10a. Therefore, the movement of the person's fingertip is stopped by hitting the rearward facing rib 10d.

  The surface of the upper handle 10 on which the fingertip of a person touches is inclined forward at a certain angle θ1 with respect to the vertical line in a side view. For this reason, when the person touches the fingertip against the finger hooking portion 10a of the upper handle 10 from above, the upper handle 10 can be rotated toward the free posture by the guide action of the inclined surface. That is, the upper puller 10 can be shifted to the free posture without performing the operation of pulling the finger-hanging portion toward the front, whereby the operation of pulling the drawer can be easily performed.

  For example, as shown in FIG. 6A, the side puller 9 has a vertically long finger-hanging portion 9a and a substrate 9b extending inward from the finger-holding portion 9a in the left-right inward direction. The upper and lower support shafts 45 are rotatably attached to a pair of upper and lower third bearing pieces 43 provided on the base 8. The support shaft 45 is the same as that used for the first interlocking member 12 and the upper puller 10, and is fitted and attached to the notch 45a formed in the substrate 9b. On the opposing surfaces of the third bearing piece 43, inclined surfaces that guide the fitting of the support shaft 45 are formed.

  As shown in FIGS. 9A and 9B, the inner end portion of the substrate 9b is in contact with or close to the passive portion 12b of the first interlocking member 12 from the front. Therefore, when the fingertip 9a of the side puller 9 is hooked and pulled, the passive portion 12b of the first interlocking member 12 is pushed backward at the inner end portion of the substrate 9b, whereby the first example moving member 12 is pivoted. Then, as described above, the second interlocking member 13 shifts to a free posture in which the stopper portion 13b is moved downward as described above. The substrate 9b of the side puller 9 is bent in a staircase shape so that the inner end portion is located behind. For this reason, the contact relationship with the 1st interlocking member 12 is securable, positioning the finger hook part 9a as near as possible.

  As clearly shown in FIGS. 10 and 11, the finger hook portion 9 a of the side puller 9 is provided with a backward-facing rib 9 c against which a human fingertip hits. For this reason, a person can obtain a soft touch. The rearward facing rib 9 c can also function as a stopper by hitting the side wall 5 b of the back plate 5. In addition, a forward rib 9 d located inside the back plate 5 is provided at the base of the substrate 9 b of the side handle 9. The forward rib 9 d overlaps with the side relief hole 15 of the back plate 5 in a side view, and therefore, the back of the end plate portion K cannot be seen through the side relief hole 15.

  As in the case of the upper puller 10, the surface of the finger hooking portion 9a of the side puller 9 that the person's fingertip touches is also tilted forward by a certain angle θ2 (see FIG. 11) in plan view. For this reason, with respect to the side puller 9 as well, the side puller 9 rotates to a free posture by applying a fingertip. For this reason, the drawer can be moved forward with ease.

  In the present embodiment, the upper puller 10 and the side puller 9 use an extruded product made of a light metal such as aluminum or a resin, and partially cut a long intermediate product into a predetermined length. It is excised into a finished product. When an extruded product is used, there is an advantage that the cost can be reduced because it is only necessary to cut in accordance with the size (width / height) of the drawer. Moreover, since it is excellent in straightness and rigidity and has no bending or warping, the rotation is smooth. In particular, it is preferable to provide ribs 9c, 9d, 10c, and 10d that protrude to the opposite sides in the front-rear direction as in the present embodiment, since the rigidity and straightness can be further improved.

  For example, as shown in FIG. 9, the board 9 b of the side handle 9 has an escape hole 9 f that allows the latch claw 11 to rotate. On the other hand, for example, as shown in FIG. 13, the inner end of the side handle 9 is located on the left and right inner sides of the cylindrical portion 13 a of the second interlocking member 13. Therefore, the escape hole 9f of the side puller 9 is set to a size that allows the cylindrical portion 13a of the second interlocking member 13 to be fitted, and the passive portion 13c of the second interlocking member 13 is connected to the root of the cylindrical portion 13a. By forming the L shape in a plan view, a collision between the side puller 9 and the second interlocking member 13 is prevented. Note that the left and right side pullers 9 are of the same type, and are used by changing the vertical and horizontal postures.

  As can be understood from FIG. 12, the driving unit 12 c having a large weight in the first interlocking member 12 is disposed so as to be shifted forward from the rotation axis O, and the passive unit 12 b is also in front of the rotation axis O. It is shifted to the side. For this reason, the first interlocking member 12 is urged by its own weight so as to rotate the drive unit 12 c downward, and the rotation due to its own weight is restricted by the pullers 9 and 10.

  Therefore, the rotation operation of the first interlocking member 12 by the pullers 9 and 10 is performed against the weight of the first interlocking member 12, and when the person releases the finger from the pullers 9 and 10, the first interlocking member 12 is operated. And each handle 9 and 10 returns to an original position (engagement state holding attitude). Therefore, the spring for returning the pulling handles 9 and 10 and the interlocking members 12 and 13 to the original posture is unnecessary. Of course, it is possible to provide a return spring. In addition, according to the said structure, since the 1st interlocking member 12 is always contact | abutting with the upper puller 10 in the non-operation state, the initial loss at the time of pulling operation can be eliminated. Furthermore, according to the above configuration, as shown in FIG. 8, since the first interlocking member 12 always tries to rotate clockwise, the first interlocking member 12 rotates counterclockwise even when the drawer is suddenly closed. Therefore, it is difficult to assume a free posture in which the stopper portion 13b of the second interlocking member 13 is moved downward, and the certainty of the locked state of the latch can be improved.

(5). Cylinder lock Next, the mounting structure of the cylinder lock 6 will be described with reference to FIG. The cylinder lock 6 used in the present embodiment is conventionally known, and includes an inner cylinder 6a having a keyhole, a main body (outer cylinder) 6b in which the keyhole is rotatably fitted, and an inner cylinder 6a. And a flange 50 that moves left and right by rotation. The front end of the inner cylinder 6a protrudes from the front end of the main body 6b, and this protrusion fits into a round hole 51 formed in the front plate 4. The flange 50 is attached to the rear part of the outer cylinder 6b so as to be slidable left and right. A pair of upper and lower slits 52 are formed at the rear end of the main body 6 b of the cylinder lock 6. On the bottom of the base 8, a pair of upper and lower auxiliary ridges 53 and a main ridge 54 are fitted with the slits 52. Is formed.

  The main body 6b of the cylinder lock 6 is held so that the slit 52 is fitted to the main protrusion 54 so that it cannot be moved up and down and cannot be removed forward, and is in contact with a rib 55 protruding inwardly on the side wall 8b of the base 8. It is held immovable outward. Moreover, the stopper nail | claw 56 provided in the bottom part of the base 8 contact | wins the inner surface of the main body 6b, and the movement to the inner side is blocked | prevented. The side wall 8b of the base 8 has a relief hole 57 for projecting the flange 50.

  The back plate 5 is formed with a first window hole 16a and a second window hole 16b, and the flange 50 is slidably fitted to the lock guide 17 attached using both the window holes 16a and 16b. waiting. The reinforcing frame 32 constituting the inner surface of the wagon body 1 is provided with a lock hole 58 into which the flange 50 is fitted and removed. In addition, since the back plate 5 partially overlaps with the front surface of the wagon body 1 in front view, it is not possible to access the bag 50 by inserting an object such as a driver.

  The lock guide 17 is made of a resin and has a hollow case shape. The lock guide 17 has a lateral foot 59 that fits into the first window hole 16a, a hook piece 60 that is hooked and engaged with the inner edge of the second window hole 16a, 2 has a claw body 61 that contacts the outer edge of the window hole 16a. In the state where the cylinder lock 6 is set, when the side piece 59 is fitted into the first window hole 16a and the collar piece 60 is fitted and pushed into the second window hole 16b from the outside, the claw body 61 is moved to the second window hole 16b. It is held in contact with the inner surface of the plate so that it cannot be removed.

(6) Operation / Summary In the state where the drawer 2 is pushed into the wagon body 1 and the pullers 9 and 10 are not pulled, the stopper portion 13b of the second interlocking member 13 is the base portion 23 of the latch claw 11 as described above. Therefore, the latch claw 11 is held in a non-rotatable manner. On the other hand, as shown by the white arrow in FIG. 9, when a person puts his finger on the finger hooks 9a, 10a of any of the pullers 9, 10 and pulls it forward, the pullers 9, 10 rotate as shown by the solid arrows. By moving, the first interlocking member 12 and the second interlocking member 13 rotate to the free posture as indicated by the black arrow, and the latch pawl 11 has its pawl portion 24 at the engagement hole of the wagon body 1. Therefore, the latch pawl 11 is turned and escaped, and the drawer 2 is allowed to move forward.

  As shown in FIGS. 10 to 12, there is a space between the outer peripheral surface of the end plate K and the front surface of the wagon body 1, and when pulling out the drawer 2, a fingertip is inserted into this space from the outside to pull the handle. The finger rests 9a and 10a of 9 and 10 are pulled.

  Further, as shown in FIGS. 10 and 12, the tips of the finger hooks 9 a and 10 a in the pullers 9 and 10 have entered the inner side by a slight dimension e from the outer peripheral surface of the front plate 4. It can prevent or remarkably suppress hitting the tips of the finger rests 9a and 10a.

  In the present embodiment, the latch claw 11 is not rotated to the free posture by the second interlocking member 13, but the restriction by the first interlocking member 13 is released and the latch pawl 11 is shifted to a free state in which the latch pawl 11 can be revolved and rotated. ing. Therefore, the latch claw 11 moves forward in a state where the tip of the claw portion 24 is in contact with the inner side surface of the wagon body 1, and returns to the original posture by the spring 30 at the same time as it is detached from the wagon body 1.

  When the drawer is pushed in, the inclined surface 24 a of the claw portion 24 of the latch claw 11 hits the front end surface of the wagon body 1. Then, the latch claw 11 moves backward along the long hole 28 and the slide guide portion 35a. That is, it slides inward without changing the posture in plan view. When the drawer 2 is fully pushed in, the latch claw 11 is moved forward by the spring 30 so that the tip of the claw portion 24 fits into the engagement hole 30.

(7). Others This embodiment can be embodied in various ways besides the above-described embodiment. For example, it can be applied to drawers of various furniture such as cabinets and desks. The end plate portion does not necessarily need to be different. In this case, the entire finger-fitting part of the handle is exposed outside the outer peripheral surface of the end plate part. Furthermore, the handle can be provided only on the upper surface portion of the end plate portion, only on the lower surface portion of the end plate portion, or on the lower surface portion and the left and right side surfaces.

  The present invention can also be applied to a case in which the latch claw moves away from the furniture body by the operation of the handle. In this case, it is also possible to directly operate the latch claw with the first interlocking member.

  The present invention can actually be drawn out and embodied. Therefore, there can be an industrial reason.
