Description

The present invention relates to a mounting and detaching process of drawer rails of drawers which are freely mounted drawer in kitchen or wash furniture vanities like.

  As is well known, as shown in FIG. 8, the drawer rail that guides the drawer so that it can be pulled out is a drawer on both side walls (one side plate 1 is shown in the illustrated example) that constitutes the drawer storage section of furniture. A required number of screw holes 2 are drilled in the rail mounting portion, and screws 5 are screwed into the screw through holes 4 provided in the required number on the mounting plate portion 3A of the drawer rail 3, and these are tightened. The current situation is that the drawer rail 3 is fixed to the side plate 1.

  However, in the above-described conventional method of attaching the drawer rail, a plurality of screws 5 must be tightened with the same torque, so that the operation is very complicated, which hinders the speedup of the furniture assembly line. Therefore, if the workability is very poor and the tightening torque is excessive, the screw pilot hole 2 is broken and the holding force of the drawer rail 3 is impaired. It had a problem of generating and deteriorating product quality. Furthermore, the deformed screw pilot hole 2 cannot be used again when the drawer rail 3 is replaced. Therefore, the installation position of the drawer rail 3 must be changed. There was also a problem that it could not be attached freely.

  In order to solve such a problem, a method using a dowel shown in Patent Document 1 has been proposed.

JP 2001-204565 A

  In the prior art disclosed in Patent Document 1, dowel holes are formed in the side plate of the cabinet, dowel protrusions are formed on the outer surface of the drawer rail, and the dowel protrusions are inserted and fitted into the dowel holes. The present invention relates to a technique for fixing the rail to the inner surface of the side plate of the cabinet with screws.

  However, even with the conventional method of attaching the drawer rail using the dowel projection, the structure is such that the drawer rail is fixed with screws in the end, so that if the tightening torque is excessive, the screw hole collapses. The holding force of the drawer rail is impaired as in the conventional example. Furthermore, the screw hole that has been deformed cannot be used again when the drawer rail is replaced. The problem of having to be changed is the same as that of the conventional example, and furthermore, when the drawer rail is removed, the engagement state between the dowel protrusion of the drawer rail and the dowel hole is robust, so this is released. Requires a lot of force, and such work is very complicated, and the dowel protrusions and dowel holes are easily deformed and often cannot be reused. Also it had a problem that.

The present invention was devised in view of the current situation, and the object of the present invention is to fix the drawer rail to the attached body with one action after the resin dowel is attached to the drawer rail. At the same time, even when removing the drawer rail, there is a method for installing and removing the drawer rail using resin dowels that can be easily removed and reused without losing the shape of the screw pilot holes, dowel protrusions, dowel holes, etc. It is something to be offered.

In order to achieve the above object, in the attachment method of the drawer rail using the resin dowel according to the first aspect of the present invention, the fastening that is detachably inserted into the through hole formed in the drawer rail A resin dowel attached to a mounting plate portion of the drawer rail via a tool , wherein the main body is formed in a substantially concave cross section, and the inner diameter of the concave hole portion of the main body is formed slightly smaller than the diameter of the through hole. In addition, after fixing at least two resin dowels formed with irregularities on the outer shape of the main body to the attachment plate portion of the drawer rail via a fastening device attached to a through hole established in the drawer rail, Each resin dowel is press-fitted into and engaged with a dowel hole of the mounted body .

The invention according to claim 2 is a case where the drawer dowel rail is removed from the attached body, and the resin dowel attached to the drawer rail is removed from the dowel hole of the attached body as described in claim 2. The resin dowel can be deformed in the recessed hole inward direction by releasing the fixing state of the resin dowel and the fastening tool fastened to the drawer rail and pulling out the fastening tool. By reducing the engagement force between the convex portion of the main body of the dowel made and the dowel hole of the mounted body, the drawer rail can be pulled out from the mounted body.

In the invention according to claim 1, the resin dowel attached to the attachment plate portion of the drawer rail through a fastening device that is detachably inserted into the through-hole formed in the drawer rail has a cross-section. Since the main body is formed in a substantially concave shape, the inner diameter of the concave hole portion of the main body is formed to be slightly smaller than the diameter of the through hole, and the outer shape of the main body is formed in an uneven shape. it is possible to fix the resin dowel into the through-hole peripheral portion of the tightly drawer rail, the outer convex portions of the resin dowels can be reliably Hamagogakaritome the dowel holes have elasticity, The drawer rail can be held strongly, and at least two or more of the resin dowels are fixed to the attachment plate portion of the drawer rail, and then each resin dowel is press-fitted into the dowel hole of the mounted body. Since it is configured to engage, it can be extracted with one action. Rails can be attached to the attached body, Therefore, the assembling work speed in furniture assembly line it is possible to greatly improve the efficiency of and productivity of the work is improved.

In the invention according to claim 2, when the resin dowel attached to the drawer rail is removed from the dowel hole of the attached body, the resin dowel and the fastening tool fastened to the drawer rail are fixed. By releasing the state and pulling out the fastening device, the resin dowel can be deformed inwardly in the concave hole portion, and the engagement force between the convex portion of the resin dowel body and the dowel hole of the mounted body is reduced. Since the drawer rail can be pulled out from the mounted body, the drawer rail can be easily removed from the mounted body, and the dowels with the fasteners removed can be crushed in the reduced diameter direction. The dowel hole can be easily removed from the dowel hole without being out of shape. Furthermore, since the dowel hole and the dowel itself are not out of shape, they can be reused and are economical. Of course, when the concave hole of the dowel body is out of shape, it is only necessary to replace the out-of-shape dowel, so that it is more economical.

  Hereinafter, the present invention will be described in detail based on embodiments of the invention shown in the accompanying drawings.

  1 is a perspective view showing an assembled state of furniture according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view showing a mounting state of the drawer rail of the furniture and a resin dowel, and FIG. 3 is a drawer rail of the furniture. FIG. 4 is a perspective view showing a state where the drawer rail is attached to the furniture, FIG. 5 is a perspective view showing a state where the drawer rail is removed from the furniture, FIG. 6 is a perspective view showing a state in which the drawer rail is attached to the furniture again, and FIG. 7 is a cross-sectional view showing an engagement state between the drawer rail according to the first embodiment and the main body side rail attached to the drawer main body side.

In the first embodiment, the mounting plate portion 13 on the flat plate extending upward from the rail portion 10A of the drawer rail 10 has a plurality of rows so that the required number of through holes 11 can be adjusted in the height direction. (In the embodiment shown in the figure, there are two rows and one row is 12 holes). Screws 12 are detachably inserted into these through holes 11, and resin dowels 20 are detachable through the screws 12. To the attachment plate portion 13 of the drawer rail 10. Note that the basic structure of the drawer rail 10 is the same as that of a conventional drawer rail that is slidably guided to the front side of the furniture so that the detailed description thereof is omitted here. Of course, in the present invention, the structure of the drawer rail itself is not limited to the one shown in the drawing, but has a substantially U-shaped cross section, a square pipe shape, a square bar shape, a round pipe shape or a round bar shape. It can apply to the drawer rail which consists of well-known various shapes.

The dowel 20 is formed of a known synthetic resin material such as nylon 6 or nylon 6-6, and its main body 21 is formed in a substantially concave shape in cross section, and the inner diameter L1 of the concave hole portion 22 of the main body 21 is The through hole 11 is formed to have a slightly smaller diameter than the hole diameter L2. In this state where the screw 12 is not screwed into the recessed hole portion 22, the upper portion of the main body 21 is bent and deformed toward the recessed hole portion 22 (reduced diameter direction) as shown by an arrow in FIG. It is configured with possible elasticity.

Further, the outer shape of the main body 21 is formed by unevenness that is continuous in the vertical direction, and the outer diameter L3 of the convex portion 23 is established on the furniture side plate 15 that is a mounted body to which the drawer rail 10 is attached. The dowel hole 16 is formed to have a slightly larger diameter than the hole diameter L4.

When the drawer rail 10 is attached to the side plate 1 using the dowels 20 configured as described above, first, screws 12 are inserted into the through-holes 11 at least at two front and rear positions formed in the attachment plate portion 13 of the drawer rail 10. And inserting the tip end portions of these screws 12 into the recessed hole portion 22 of the dowel 20, and then rotating the screw 12 to fix the dowel 20 to the back side of the mounting plate portion 13. This operation can be performed in advance before assembling the furniture on the assembly line. In this state, the drawer rail 10 to which the dowel 20 is attached is used for the dowel hole 16 of the side plate 15 using a hammer or the like in the assembly line. The drawer rail 10 can be easily attached to a predetermined position of the side plate 15 (see FIG. 4). In this case, since the convex portion 23 of the dowel 20 is pressed against the peripheral surface portion of the dowel hole 16 with a strong elastic force, a sufficient holding force of the drawer rail 10 can be obtained.

In the first embodiment, since the through holes 11 are formed in two upper and lower rows, the height can be adjusted according to the size of the furniture to which the drawer rail 10 is attached, and 12 pieces are arranged in one row. Since the through-hole 11 is opened, fine adjustment in the depth direction is also easy.

Next, when removing the drawer rail 10, as shown in FIG. 5, the drawer rail 10 can be removed from the side plate 15 simply by rotating the screw 12 in a non-tightening direction with a tool such as a screwdriver. it can. At this time, since the dowel 20 is left while being press-fitted into the dowel hole 16, there is no concern that the dowel hole 16 may lose its shape due to the removal operation. Even when the dowel 20 is removed from the dowel hole 16, the dowel 20 with the screw 12 pulled out can be deformed in the direction of the recessed hole portion 22, and therefore the engagement force (pressure contact force) with the dowel hole 16 is large. Since it is weak, it can be easily pulled out of the dowel hole 16 with a screwdriver or a tool such as a thousand pieces.

When the drawer rail 10 is attached to the side plate 15 again from this state, as shown in FIG. 6, the tip end portion of the screw 12 is inserted from the through hole 11 toward the concave hole portion 22 of the dowel 20 and tightened. Thus, the drawer rail 10 can be easily attached. At this time, since the dowel hole 16 does not have to be damaged by the screw 12, the holding force of the drawer rail 10 is not impaired, and a strong holding force can be obtained.

As shown in FIG. 7, the drawer rail 10 fixed to the side plate 15 of the furniture in this way is connected to the other end portion of the main body side rail 33 formed by fixing one end portion to the bottom plate 31 of the drawer main body 30 with screws 32. The formed rail portion 34 is configured to be slidably engaged with the drawer rail 10. With this configuration, the rail portion 34 is slid and guided along the longitudinal direction of the drawer rail 10 with a light operating force, so that the drawer body 30 can be pulled out smoothly. In the figure, reference numeral 35 denotes a side plate of the drawer body 30.

  In the first embodiment, the case where the drawer rail 10 is removed from the side plate 15 and the case where the screw 12 is loosened and removed are described as examples. However, the present invention is not limited to this example. When the hole 16 is formed through, the dowel 20 can be removed by pushing the bottom surface of the dowel 20 with a screwdriver or the like to release the engagement state between the dowel 20 and the dowel hole 16. In this case, since the removing operation does not require the rotation operation of the screw 12, the attaching operation and the removing operation can be performed with one action, and the workability is greatly improved.

  Since the resin dowel according to the present invention and the method of installing / removing the drawer rail using the resin dowel are configured as described above, the assembly efficiency in the furniture assembly production line having the drawer storage portion Production efficiency can be greatly improved, and production efficiency can be greatly improved.
