Description

  The present invention relates to a pulling device provided on a drawer or door with a latch device in furniture such as a cabinet, or a pulling device provided on a door with a latch device in a building, and furniture including the pulling device. Here, the door includes both a rotating type (sliding door type) and a sliding type.

  Latch devices are often provided on drawers and doors of furniture (for example, cabinets and desks). This latch device is designed so that the latch pawls can be disengaged from the engaging portion of the main body when the lever (pull handle) of the pull device is pulled. It has become. The structure of the latch device varies, but from the perspective of the attachment relationship with the drawer and door, the lever and the support to which it is attached are unitized and attached to the drawer and door, and the lever support portion on the drawer and door It can be said that (for example, a bracket) is roughly divided into those provided by welding or the like.

  When the pulling device is unitized, there is an advantage that it is easy to assemble the drawer and the door and eliminate the assembly failure due to the processing error of the member. On the other hand, since the number of members increases, it takes time to assemble the unit itself. There are problems such as this tendency, and if the specifications are different, parts must be manufactured individually, so that flexibility is poor.

On the other hand, for example, when referring to a drawer pulling device, there is a case where the lever is arranged at the left and right intermediate portion of the end plate with a length much shorter than the lateral width (frontage dimension) of the end plate in the drawer. as there has a case where the length extending over the left and right substantially the entire length of the end plate of the lever, when adopting the form Patent Document 1, excellent operability of the drawer operation because it can operate the lever from left any position of the end plate In addition, since both hands can be hung on the lever, there is an advantage that a heavy drawer can be easily pulled out.
JP 2004-89220 A

  In Patent Document 1, a member (bracket device) for rotatably supporting the lever is fixed to the rear surface of the end plate. However, in this configuration, if the processing error of the bracket device or the error of the mounting position is large, the drawer is pulled out. There was a risk of hindering assembly. Also, because the lever is connected to the bracket device with a shaft, it has a large number of members and tends to be troublesome to manage and assemble, and the lever is supported by the left and right bracket devices even though it is long. Therefore, there is a problem that the support stability of the lever may be lowered.

  The present invention has been made to improve the current situation.

  The pulling device according to the present invention includes a "support that is fixed to a movable body such as a drawer or a door, and a lever that is rotatably attached to the support, and the lever includes the lever and the lever. The support body is rotatably held by fitting a male engagement portion provided on one of the supports and a female engagement portion provided on the other, and is latched by rotation of the lever. The basic structure is “the latch claw of the device is disengaged”.

In the first aspect of the present invention, in the above basic configuration, first, the male engagement portion is a protrusion having a head that swells in a substantially circular shape in a cross-sectional view taken along a plane orthogonal to the rotation axis of the lever. On the other hand, the female engaging portion is a groove in which the head of the protrusion is fitted, and the protrusion and the groove are a direction along the rotation axis of the lever and the support body. It is fitted by relative movement.
Further, in the first aspect of the invention, the movable body includes an end plate that forms the front surface of the movable body, and the support body is attached to the end plate so that the support body is exposed. And a pressing portion that is located inside the end plate and that rotates the latch claw in the disengagement direction. The finger hanging portion and the pressing portion are provided on the lever. It is located on the opposite side across the center of rotation, and a relief hole is provided in the end plate for allowing the pressing portion of the lever to enter inside the end plate.

According to a second aspect of the present invention, in the configuration of the first aspect, the support and the lever are manufactured by extrusion molding using a metal or a resin as a raw material, and the pressing portion of the lever cuts an unnecessary portion after the extrusion processing. By doing so, the length is shorter than the finger-hanging portion.

The present invention includes a cabinet with a drawer as an example where a puller device is used. That is, as described in claim 3, the cabinet includes a main body opened forward and a drawer disposed therein, and the pulling device according to claim 1 or 2 is attached to the end plate of the drawer. the support and the lever of the pull device extends over the left and right substantially the entire length of the end plate.

In the pulling device according to the present invention, the latch is released by turning the lever. The latch is released when a person puts his finger on the finger hooking portion of the lever and pulls it forward. And a mode in which the latch is released by manually pushing the finger-hanging portion . That is, the lever may be a puller or a pusher.

  In the invention of the present application, the support and the lever are not required to have another member for the lever to be rotatable because the protrusion also serves as the rotation shaft and the groove also serves as the bearing. The structure can be simplified by suppressing the number of points, and the assembly of the movable body such as the assembly of the pulling device and the drawer is easy. Further, the support is attached to a movable body such as a drawer or a door, and the support strength of the lever is excellent.

As a means to attach the lever to the support so as to be rotatable, the lever is provided with a shaft portion, while the support is provided with a bifurcated receiving portion into which the lever shaft portion is fitted, and the receiving portion is elastically deformed. In this method, there is a problem that the shaft portion of the lever is easily detached from the receiving portion of the support body, and therefore it is necessary to provide a stopper. On the other hand, in the present invention, since the protrusion and the groove are fitted from the direction along the rotation axis of the lever, the protrusion does not come out of the groove when the lever is used. Although it is a structure, a fitting state can be ensured.

There are various sizes of drawers and doors. For this reason, many types of pulling devices having different lengths of the support and the lever are required. And when a support body and a lever are manufactured by extrusion processing as in claim 2, a long intermediate member (several meters or 10 m or more) is manufactured as a material for the support body and the lever, and this intermediate member Is cut into a length corresponding to the type of the pulling device, so that it is possible to deal with a pulling device having an arbitrary length. Therefore, when configured as claim 2, in size to produce a different type of pull devices, it can be significantly reduced manufacturing cost of the entire pull device group.

Further, for example, in the drawer, there are three types of arrangement modes of the latch claw placement (latch claw): a case where it is provided on both left and right sides of the end plate and a case where it is provided on only one of the left and right sides of the end plate. . When produced by extrusion lever as claimed in claim 2, the predetermined pressing portion for operating the latch pawl in a state before the intermediate member to be cut to a length longer extension Biteiru entire length is, the arrangement of the latching device Since the pressing part is cut according to the mode, the width dimension of the escape hole provided in the end plate can be shortened to prevent the end plate from being lowered in strength.

  Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 show the first embodiment, and FIG. 5 shows the second embodiment. First, the first embodiment will be described.

FIG. 4B is a side sectional view, and FIG. 4B is a sectional view taken along the line B-B in FIG. In FIG. 3, the end cap 9 is omitted.

As shown in FIG. 3 and FIG. 4, the end plate 3 includes a back plate 3 c , and a protrusion 12 having a square shape in a rear view is integrally fixed to the back plate 3 c . The upper surface of the projecting portion 12 is the same height as the upper surface of the back plate 3 c in the end plate 3, while the left and right side surfaces of the projecting portion 12 are located inside the left and right side surfaces of the end plate 3. The front portion of the storage portion 4 is fixed to the end plate 3 so as to surround the protrusion 12. The base of the latch claw 8 enters the inside of the end plate 3, and therefore, the back plate 3 c of the end plate 3 has a latch hole 13 for exposing the latch claw 8.

  In the present embodiment, the latch claw 8 is provided only on the left side of the end plate 3 in front view (of course, it can be provided on both the left and right sides, or on the right side in front view). In FIG. 3, the latch claw 8 is drawn close to the left end of the end plate 3, but this is for convenience of drawing, and actually the latch claw 8 is stored as shown in FIG. Close to part 4.

As shown in FIG. 3 and FIG. 4 (A), a vertical pivot shaft 14 is fitted to the base of the latch claw 8 so as not to be relatively rotatable, and the pivot shaft 14 is a back plate of the end plate 3. It is supported by a plurality of horizontal shaft support pieces 15 fixed (or cut and raised) on 3c so as to be horizontally rotatable, and at the upper end of the rotating shaft 14, a horizontal shape extending to the position of the protrusion 12 is provided. The operation portion 14a is bent. Therefore, when the operation portion 14a is pushed backward and the rotation shaft 14 is rotated clockwise in plan view, the latch claw 8 is detached from the engaging portion (not shown) of the main body 1.

  The latch claw 8 is made of resin. As shown in FIGS. 3 and 4, the latch claw 8 extends horizontally toward the center of the end plate 3 toward the base, and on the back surface of the substrate 3 a on the end plate 3. The elastic piece 8a which contacts is provided integrally. Due to the spring force of the elastic piece 8a, the latch claw 8 is urged to engage with the engaging portion of the main body 1 and become free. In addition, although the latch claw 8 of this embodiment forms the engagement hole 8b as an engagement part engaged / disengaged with the engagement part of the main body 1, you may provide a nail | claw as an engagement part.

  The rotation of the lever 7 in the pulling device 5 is transmitted to the rotation shaft 14 via an intermediate interlocking member 16 made of a wire rod disposed in a space surrounded by the protrusion 12 and the end plate 3. The intermediate interlocking shaft 16 includes a horizontal portion 16a, an upward portion 16b provided at one end of the horizontal portion 16a, and a downward portion 16c provided integrally with the other end of the horizontal portion 16a, and is formed in a crank shape as a whole. ing.

  The horizontal portion 16 a of the intermediate interlocking member 16 is rotatably supported by a vertical bracket 17 fixed to the inner surface of the protrusion 12. In this case, the horizontal portion 16 a of the intermediate interlocking member 16 is fitted into the upward bearing hole 18 formed in the vertical bracket 17 from above. The vertical brackets 17 are arranged on the left and right so as to be sandwiched between the upward portion 16b and the downward portion 16c of the intermediate interlocking member 16, so that the intermediate interlocking member 16 is held so that it cannot be displaced left and right. In the present embodiment, the latch device is configured with the latch claw 8, the rotation shaft 14, and the intermediate interlocking member 16 as main members (moving members).

(3) Pulling device The support 6 and the lever 7 of the pulling device 5 are both manufactured by extrusion processing using a metal such as aluminum or aluminum alloy. The support 6 includes a cover portion 10 which protrudes above the end plate 3, and an L-shaped shoulder 20 that overlaps the upper rear as a whole of the upper surface of the projecting portion 12, forward from the lower end of the cover portion 10 The auxiliary horizontal portion 21 is held by a holding portion 22 formed on the upper piece 3 e of the end plate 3. In addition, the upper end part of the end plate 3 is in an overlapped state with the upper piece 3e and the reinforcing piece 3f.

The cover portion 10 of the support 6 in the pulling device 5 has a forward-facing portion 10a that extends toward the front with a space between the upper surface of the end plate 3, so that the cover portion 10 as a whole is viewed in side view. The shape is close to a letter shape. The upper surface of the forward facing portion 10a in the cover portion 10 is curved so that a human finger can be easily inserted. And the downward protrusion 23 is integrally formed in the front end of the front part 10a in the support body 6. As shown in FIG. The ridge 23 is composed of a substantially circular head 23 a and a narrow neck 23 b that connects the head 23 a and the forward facing portion 10 a of the cover 10.

  On the other hand, the lever 7 is provided with the above-described finger hooking portion 11, and a groove portion 25 having a groove 24 surrounding the head 23 a of the protrusion 23 in the support 6 is integrally formed at the lower end of the finger hooking portion 11. Is formed. The groove portion 25 is naturally open, but the width of the opening portion is larger than the thickness of the neck portion 23b of the protrusion 23, and therefore the lever 7 is allowed to rotate. The outer surface of the lower end of the front portion of the groove portion 25 has a shape close to a right angle in a side view, but may be formed in an arc shape concentric with the groove.

The groove portion 25 of the lever 7 is integrally formed with a plate-like downward pressing portion 26 that comes into contact with the upward portion 16b of the intermediate interlocking member 16 from the front side, and the pressing portion 26 is an upper piece 3e of the end plate 3 And the inside of the end plate 3 through a relief hole 27 provided in the reinforcing piece 3f at the upper end of the back plate 3c. Since the lever 7 is manufactured by extrusion processing as described above, the pressing portion 26 is formed over the entire length in the state of extrusion processing, and unnecessary portions are cut out so as to remain only at necessary portions after the extrusion processing. . According to this embodiment, the lever 7 can be reduced in weight, and the width dimension of the escape hole 27 opened in the upper piece 3e of the end plate 3 and the reinforcing piece 3f of the back plate 3c can be shortened to prevent a decrease in strength of the end plate 3. When the latch device (latch claw 8) is disposed on both the left and right sides of the end plate 3, two pressing portions 26 are provided on the left and right.

  As shown in FIG. 2C, screw holes 28 are formed at appropriate intervals along the left-right direction in the hanging piece of the shoulder portion 20 in the support 6, and the countersunk screw is passed through this screw hole 28. The support 6 is fixed to the end plate 3 by screwing 29 into the protrusion 12 of the drawer 2. Since the auxiliary horizontal portion 21 is pressed by the holding portion 22 of the end plate 3, the support 6 is held in a stable state even when an external force from the front acts.

  As shown in FIG. 2, the end cap 9 overlaps the cover portion of the support 6 and the groove-like portion 25 of the lever 7, and is fastened to the cover portion 10 of the support 6 with a countersunk screw 30. For this reason, the lever 7 is held so that it cannot be removed from the left and right. A tapped hole 31 for screwing the countersunk screw 30 is provided in the cover portion 10 of the support 6. The prepared hole of the tap hole 31 can be drilled after the extruding process. However, if it is formed in advance by the extruding process, labor can be saved. The end cap 9 is formed with a laterally extending portion 9 a that overlaps the back surface of the cover portion 10 in the support 6.

(4) Summary The support body 6 and the lever 7 constituting the pulling device 5 are assembled by a one-touch operation in which both are moved relative to each other in the axial direction and the protrusion 23 is fitted into the groove 24. Since the ridge 23 serves as a support shaft and the groove 24 serves as a bearing, no other member for shaft support is required, and thus the configuration is simple. Moreover, mounting the ridges 23 and the grooves 24 because it does not fit only in the axial direction slide, for example the lever 7 be pulled strongly lever 7 is none the Turkey off from the support 6, a high order the Strength is secured.

Moreover, in this embodiment, since the auxiliary | assistant horizontal part 21 of the support body 6 is hold | maintained by the holding part 22 of the end plate 3, only the shoulder part 20 in the support body 6 is fastened to the protrusion 12 with the screw | thread 29. The pulling device 5 is firmly fixed to the end plate 3. This is an advantage of the present embodiment. Incidentally, the projections 12 are those also say part of the end plate 3, therefore, the fastening structure of the present embodiment, the supporting member 6 on the rear surface member of the end plate 3 may be paraphrased as you are fastened with screws 29.

  By the way, since the front surface of the end plate 3 in the drawer 2 is in contact with the human eye, it is necessary to perform a cosmetic treatment such as painting. However, if a decorative steel plate that has been surface-treated in advance is used, the labor of processing can be suppressed. However, if a blanket material is welded to the back surface of the substrate 3a, the decorative layer on the surface is damaged by heat. On the other hand, in the present embodiment, the brackets constituting the latch device are provided on the back plate 3c or the protrusion 12, and even if they are welded, the aesthetic appearance is not affected, and the pulling device 5 is screwed. Therefore, this will not affect the aesthetics. This is an advantage of the present embodiment.

(5). Second Embodiment In the second embodiment shown in FIG. 5, the support 6 of the pulling device 5 is formed in a form having a pulling hole opened forward, and a lever 7 is provided below the support 6. It is attached. However, in the present embodiment, contrary to the first embodiment, the protrusions 23 are formed on the lever 7 and the grooves 24 are formed on the support 6. The point which fastens the shoulder part 20 to the protrusion 12 is the same as 1st Embodiment. When the groove 24 is formed on the support body 6 as in this embodiment, the screw for fixing the end cap 9 can be screwed into the groove 24 of the support body 6.

(6). Others The present invention can be embodied in various ways other than the above embodiment. For example, the form (cross-sectional shape) of a support body and a lever can be arbitrarily set according to a use. Further, the structure of the latch device is not limited to the embodiment, and in some cases, the pivot shaft of the latch claw can be directly rotated by the lever. Further, the latch claw of the latch device is not limited to the pivoting type, and may be a retractable type. When applied to a horizontally-rotating door, generally, a vertically long latch rod will be rotated by a lever.

Also, when applying the puller device of the present invention to the drawer, need not name the pull device is necessarily length extending over the right and left the entire length of the end plate. Further, in the present invention, the protrusion and the groove do not necessarily have a length extending over the entire length or substantially the entire length of the support and the lever, for example, the protrusion and the groove are not necessarily left and right of the support and the lever. The length and position of the protrusion and the groove can be arbitrarily set such that the intermediate portion and the left and right ends are fitted together.
