Description

  The present invention relates to a mounting structure for a back plate used as a back plate on the back surface of a box portion such as furniture or a cabinet.

  Conventionally, the back plates of boxes such as furniture and cabinets are attached to the top plate 12, the base plate 13, the left and right side plates 14 of the box 11, and the back side end surfaces 12a, 13a, 14a and 15a of the partition plate 15 as shown in FIG. The back plate 16 was brought into contact with the nail or screwed from the outside of the box 11 using a nail N or a wood screw.

  In addition, as a method of assembling the box without nailing the back plate, etc., a groove for inserting the back plate into the left and right side plates of the box and the ground plate is formed, and the back plate is inserted into the groove, and between the upper ends of the left and right side plates. There is a description of a cabinet in which members are arranged as an assembly and a back plate construction method thereof. (For example, refer to Patent Document 1).

JP 2003-265241 A (page 1-5, FIG. 1-2)

  However, in the above prior art, in the cabinet and its back plate construction method described in Japanese Patent Application Laid-Open No. 2003-265241, the grooves for inserting the back plate into the left and right side plates, the ground plate, etc. are processed with high accuracy. There is a problem that if the processing accuracy is low, the back plate cannot be inserted into the processed groove, making assembly impossible. Therefore, extremely high accuracy and high quality are required as groove processing accuracy, and high-precision processing machines and skilled workers are required for that purpose. Furthermore, the back plate mounting structure has a complicated structure, and is high in manufacturing technology in combination with high-precision processing, and has a high cost.

  Further, among the above prior arts, the method of driving nails, wood screws, etc. from the outside of the back plate seems simple at first glance, but there are various problems described below. That is, the thickness of each member panel such as the top plate, the ground plate, the left and right side plates, the partition plate is about 15 to 20 mm, and nailing the outer surface of the back plate aiming at the muzzle surface of each member panel, Or, screwing a wood screw does not show the wood face of each member panel from the outside of the back plate, so the tip of the nail or wood screw comes off the wood face of the member panel and damages the nail or removes the wood screw. There were many cases of screwing failure.

  In particular, the nail or wood screw driving position on the partition plate is difficult to see from the outside of the box, and the tip of the nail or wood screw comes off the wood surface of the component panel, and the nail is damaged. It was especially a big problem because it was often screwed down.

  For this reason, there is a method in which a line for identification is marked with a pencil or other writing tool at the position where the back plate nail or wood screw is driven, and used as a mark. According to this method, the problem of damaging nails and wood screws can be avoided. In other words, the wood face of each member panel is not visible from the outside of the back plate, so in the case of each member panel, especially a partition plate, the nail or wood screw driving position is difficult to understand, and the tip of the nail or wood screw is not visible on the member panel. There are many problems that come off the end of the wood and damage nails and wood screws, but this problem can be avoided.

  However, according to the above method, the mark line attached to the back plate is unclear, and the back plate is usually made of plywood having a thickness of about 3 to 5 mm as a base material. The back side of the plywood often has defects such as knots, discoloration, and decay compared to the plywood surface, and the marked lines are often difficult to see. Further, when the plywood base material is old, it is often tanned or discolored as a whole, and the mark lines are often unclear. In addition, the mark line often fades with time.

  In addition, in the case of the mark line as described above, not only the line itself becomes unclear, but even if you intend to drive a nail or a wood screw rather than the mark line, it may be damaged by hand. There were many. In particular, a notch step having a notch depth substantially equal to the thickness of the back plate is provided on the back side of the left and right side plates, and the back plate is fitted between the left and right notch steps and fixed with nails or wood screws. In this case, it is preferable for the driving direction to be inclined toward the corner direction of the notch step, rather than perpendicular to the back plate, and for the direction of the corner of the notch step. In the case of slanting toward the top, nailing is superior to workability than wood screws. However, in particular, when nailing is performed using a nail, this slanting has a lot of damage unless it is a skilled craftsman, and if it is not assembled carefully, the finished quality is inferior. In addition, there is a problem that the tip of a nail or the like slips and is damaged when slanted. Accordingly, it has been a big problem to find a back plate structure that is hard to break when the nails are slanted.

  In addition, in the case of the mark line as described above, there is a risk that when a person with reduced vision assembles, the mark line is misread and the mark line and the nail or wood screw driving position are greatly displaced, resulting in damage. was there.

  In addition, when a nail or a wood screw is driven into the back plate at a predetermined position and the head of the nail or wood screw protrudes from the back of the back plate, after assembling the box, a box such as furniture is installed in front of the wall. When the box is brought into contact with the wall surface, there is a risk that the wall cross or the like may be scratched and damaged by the protruding nail head or wood screw head.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to identify the nail or wood screw driving position from the outside of the box by the function of the back plate mounting position identification display as a mark line. Because it is easy, it has a back plate mounting structure that does not damage nails and wood screws, and even if there are many defects such as nodes, discoloration, decay, etc. on the back of the back plate, the back plate is old and tanned Even if the color changes, the mark line does not become blurred, and the mark line does not fade due to changes over time.In addition, the nail is placed toward the corner of the notch on the side plate. It is suitable for workability when hitting diagonally, even for people with weak visual acuity, there is no damage, and the tip of a nail etc. does not slip and damage when inclined, Nail heads etc. are buried in the groove as the identification position indication Do not protrude, is to provide an inexpensive back plate mounting structure of the furniture is no risk of such damaging by scratching a cloth or the like of the wall surface at the protruding nail head and wood screw head.

  The furniture back plate mounting structure according to claim 1, which has been made to solve the above problems, is a furniture box comprising a top plate, a base plate, left and right side plates, a partition plate, and a back plate. The top plate touches the top plate, the ground plate, the left and right side plates, and the back side of the partition plate, and the back plate is attached and fixed by mechanical attachment means according to the back plate attachment position identification display provided on the back surface of the back plate. It is characterized by that.

  According to the back plate mounting structure of the present invention having such a configuration, the position of the nail or the wood screw is difficult to understand because the wooden face of each member panel cannot be seen from the outside of the back plate. In this case, the driving position of the nail or the wood screw is difficult to understand, and it is possible to avoid the problem that the tip of the nail or the wood screw comes off the cuff surface of the member panel and damages the nail or the wood screw.

  The furniture back plate mounting structure according to claim 2 is the furniture back plate mounting structure according to claim 1, wherein the back plate mounting position identification display is formed on a back surface of the back plate. And a groove having dimensions, and the mechanical attachment means is nail nailing.

  According to the back plate mounting structure of the furniture of the present invention having such a configuration, since the back plate mounting position identification display is a groove, the mark line attached to the back plate is unclear, or the back plate back surface is Even if there are defects such as tanning, discoloration, knots, discoloration, decay, etc., the mark lines do not become difficult to see. In addition, the mark line does not fade due to changes over time. In addition, nailing with nails is superior to the threading with wood screws, and the work of attaching the back plate is greatly improved by nailing into the grooves. Further, even for a person with weak visual acuity, the groove is easy to identify and is not damaged. Further, since the nail head is buried in the groove, it is possible to provide an inexpensive back plate mounting structure without the risk of scratching and damaging the wall cross or the like with the protruding nail head or the like.

  The back plate mounting structure for furniture according to claim 3 of the present invention is the back plate mounting structure for furniture according to claim 1 or 2, wherein the top plate, the base plate, and the back plate on the back side of the left and right side plates. A notch step having a notch depth substantially equal to the thickness of the back plate is provided, and the width and height dimensions of the back plate are smaller than the width dimension and the height dimension between the sides of the notch steps facing each other. The position identification display is a groove having a substantially V shape in a sectional view.

  According to the furniture back plate mounting structure of the present invention having such a configuration, a notch step portion for fitting the back plate to the left and right side plates is provided, and when attaching the back plate to the notch step portion, particularly a nail or When attaching a backboard by slanting a wood screw or the like, nailing is better. Thus, the back plate attaching workability is greatly improved by diagonally nailing. Further, if the groove as the back plate mounting position identification display is a groove having a substantially V-shaped cross-sectional view, in the case of oblique nail driving, the nail is formed with respect to the groove wall surface of the groove having the V-shaped cross-section. Can be driven almost vertically, so the operation of diagonally driving the nail is very simple, the back plate mounting workability is good, and the nail can be driven with high mounting accuracy.

  According to the first aspect of the present invention, the position of the nail or the wood screw is difficult to understand because the face of each member panel cannot be seen from the outside of the back plate. It is difficult to understand the screw driving position, and it is possible to avoid the problem that the tip of the nail or the wood screw comes off the wood face of the member panel and damages the nail or the wood screw.

  According to the invention described in claim 2, since the back plate mounting position identification display is a groove, the mark line attached to the back plate is unclear or the back surface of the back plate is old and tanned. Even if there are defects such as discoloration, knots, discoloration, and decay, the mark lines will not be difficult to see. In addition, the mark line does not fade due to changes over time. In addition, nailing with nails is superior to the threading with wood screws, and the work of attaching the back plate is greatly improved by nailing into the grooves. Further, even for a person with weak visual acuity, the groove is easy to identify and is not damaged. Further, since the nail head is buried in the groove, it is possible to provide an inexpensive back plate mounting structure without the risk of scratching and damaging the wall cross or the like with the protruding nail head or the like.

  According to the third aspect of the present invention, the notch step portion for fitting the back plate to the left and right side plates is provided, and when attaching the back plate to the notch step portion, in particular, a nail or a wood screw is hit diagonally. When attaching the back plate, nailing is better. Thus, the back plate attaching workability is greatly improved by diagonally nailing. Further, if the groove as the back plate mounting position identification display is a groove having a substantially V-shaped cross-sectional view, in the case of oblique nail driving, the nail is formed with respect to the groove wall surface of the groove having the V-shaped cross-section. Can be driven almost vertically, so the operation of diagonally driving the nail is very simple, the back plate mounting workability is good, and the nail can be driven with high mounting accuracy.

  Details of the present invention will be described with reference to the drawings. 1 is a perspective view showing a first embodiment of the back plate mounting structure of the present invention, FIG. 2 is a horizontal sectional view of the first embodiment of the present invention, and FIG. 3 is an explanatory diagram of the first embodiment of the present invention. An enlarged horizontal cross section is shown. FIG. 4 is an enlarged horizontal sectional view of the main part of the second embodiment of the present invention.

  1-3, the first embodiment of the back plate mounting structure of the present invention will be described in detail. The furniture box 1 of the present invention includes a top plate 2, a base plate 3, left and right side plates 4, a partition plate 5, and a back plate 6. Although not shown, an opening door or a sliding door is provided on the front surface of the box 1. In this example, the partition plate 5 is attached as a vertical partition plate in the height direction between the top plate 2 and the base plate 3 at a position slightly to the right when the box 1 is viewed from the back side. An example of division is shown. In addition to the example of the vertical partition plate provided in the height direction shown in this example, the middle partition plate 5 is provided in the horizontal direction (horizontal direction), although not shown, and the box 1 may be divided into two vertically. In the case, it becomes a horizontal partition.

  Although not shown, the vertical partition plate and the horizontal partition plate may be two or more in addition to the case of one, and the box 1 may be divided not only into two but also into three or more. However, there are some complicated boxes that have both vertical and horizontal dividers. In any case, the back plate mounting structure of the present invention will be described with a relatively simple box 1 provided with one vertical partition plate shown in the perspective view of FIG. Are the same.

  In the first embodiment of the back plate mounting structure of the present invention, the back plate 6 has a surface on the back side cuff surface 2a of the top plate 2, a back side cuff surface 3a of the base plate 3, back side cuff surfaces 4a of the left and right side plates 4, and a partition plate. 5, a nail N or a wood screw or the like is attached to the back plate 6 by nailing or screwing substantially perpendicularly to the back plate 6. At this time, the back plate 6 is attached from the back side (outside of the box 1) using mechanical attachment means such as nailing using a nail N or the like or screwing with a wood screw. That is, it is substantially perpendicular to the back plate 6 toward the back side cuff surface 2a of the top plate 2, the back side cuff surface 3a of the main plate 3, the back side cuff surface 4a of the left and right side plates 4, and the back side cuff surface 5a of the partition plate 5. It is a method to attach from. In this example, a case where a nail N is driven and attached by a nail attachment method is illustrated. The nail driving position of the nail N is not visible from the back side of the back plate 6, and in particular, the nail driving position of the back side cuff surface 5 a of the partition plate 5 is not visible at all. Since it is driven with an approximate position, if the craftsman's skill is inferior, it will be easily damaged, and the finished quality will be inferior. Therefore, in the back plate mounting structure of the present invention, the back plate mounting position identification display M is provided in advance at a predetermined position on the back surface of the back plate 6.

  This identification display M is not a line drawn with a writing instrument such as a conventional pencil or ink, but a groove J having a predetermined cross-sectional shape. The groove J is provided in advance in the nail driving position of the back plate 6.

  As the cross-sectional shape of the groove J, a square shape, a trapezoidal shape, or the like can be used in addition to a V-shaped sectional view, a U-shaped sectional view, or the like. However, among these, the groove J having a V-shaped cross section is most preferable. The reason is that the back plate mounting structure according to the first embodiment of the present invention is a system in which a nail N and a wood screw (not shown) are mounted on the back plate 6 from a substantially vertical direction. A mechanical attachment means such as a nail N or a wood screw (not shown) has a pointed tip, and when the nail is nailed substantially perpendicularly to a V-shaped groove J in cross section, the pointed tip is the groove J. The position of the nail N or the like is easily determined in the V-shaped valley. In other words, unless it was a skilled worker, the tip of the nail slipped on the back of the back plate when nailing, and damage was often caused. However, due to the action of the groove J, the sharp tip has a V-shape of the groove J. Since the position of the nail N or the like is easily determined, the back plate attaching workability is greatly improved, and it is also suitable for improving the quality of the construction finish. That is, the nailing operation is easily performed without shifting the nail driving position, which is suitable for workability and finished quality. Further, since the nail head or the like is buried in the groove J and does not protrude outward, even if the box 1 is pressed against the wall surface of the room, there is no risk of scratching the cosmetic material such as the wall cross with the nail head.

  In addition, the size of the groove J is preferably the following dimension. That is, the thickness dimension of the back plate 6 is usually about 3 to 9 mm. The depth dimension of the groove J is preferably about 10 to 30% of the thickness dimension of the back plate 6 for the nailing workability, the finished quality, and the strength of the back plate itself. Although the depth dimension of the groove J depends on the thickness dimension of the back plate 6, for example, when the thickness of the back plate 6 is about 3 mm, the depth dimension of the groove J is about 0.3 to 1.0 mm. Is preferred. If the depth is less than about 0.3 mm, the groove J is difficult to identify, and the tip of the nail may slip, and if it is deeper than about 1.0 mm, the strength of the back plate 6 is marked at the position of the groove J. It will drop and cause damage. Further, when the thickness of the back plate 6 is relatively thick, such as about 4 to 9 mm, it may be a little deeper. The width dimension of the groove J needs to be conspicuous as an identification display, and is preferably about twice the depth of the groove J as one guide.

  One of the methods for processing the groove J is a cutting method using a cutter blade (not shown). In addition, there is a method of applying a pressing process using a pressing jig. For the cutter blade, for example, a cutter blade having a groove cross-sectional shape and a groove size matched to the groove cross-sectional shape and groove size is attached to a cutting machine such as a groover or a tenor, and the groove J having a predetermined cross-sectional shape and size is processed by cutting.

  Although the method for processing the groove J by pressing with the pressing jig is not shown, for example, a pressing roll is prepared and the pressing roll or spine is held while the back plate 6 is sandwiched between the pressing roll and the feeding roll. The plate 6 is fed forward. At this time, the gap between the pressing roll and the feed roll is set to a dimension smaller than the thickness dimension of the back plate 6 by a dimension corresponding to a predetermined groove depth. The cross-sectional shape of the outer peripheral portion of the pressing roll is a shape that matches the groove cross-sectional shape of the groove J.

  There is also a method of processing the groove J using a flat plate press. At this time, an embossing press plate (not shown) in which a pressing projection (not shown) having a shape in plan view corresponding to the back plate attachment position indication to be provided on the back surface of the back plate 6 is prepared. The pressing protrusion side is brought into contact with and pressed against the back surface of the back plate 6 to form a predetermined groove J on the back surface of the back plate 6. At this time, the tip of the pressing protrusion is shaped to match the groove cross-sectional shape of the groove J. Moreover, it is necessary to adjust the depth of the groove | channel J suitably by the pressure adjustment of the said embossing press board.

  Further, the back plate 6 may be divided at the partition plate 5 or may be a single back plate. In the case of a divided back plate (not shown), it is necessary to drive nails or the like in two rows along the rear side cuff surface 5a of the intermediate partition plate 5 at the location of the intermediate partition plate 5. Because it can be reliably identified by, there is no damage.

  In FIG. 4, the second embodiment of the back plate mounting structure of the present invention will be described in detail. A notch step portion 7 is provided on the back side front end 2 a of the top plate 2, the back side front end 3 a of the base plate 3, and the back side front end 4 a of the left and right side plates 4. The depth dimension of the notch portion of the notch step portion 7 is substantially equal to the thickness dimension of the back plate 6. That is, the distances between the back-side front end 2a of the top plate 2, the back-side front end 3a of the base plate 3, the back-side front end 4a of the left and right side plates 4, and the bottom 7b of the notch step 7 are as follows. It is substantially equal to the thickness dimension.

  Also in the second embodiment of the present invention, as in the first embodiment, the back plate 6 may be divided at the location of the partition plate 5 or a single back plate. It may be. In the case of a divided back plate (not shown), it is necessary to drive nails or the like in two rows along the rear side cuff surface 5a of the intermediate partition plate 5 at the location of the intermediate partition plate 5. Because it can be reliably identified by, there is no damage.

  In addition, the width dimension of the back plate 6 (in the case of the divided back plate divided into the left and right sides, the width dimension when the left and right end surfaces of the divided back plates are brought into contact with each other) is provided on the back side cuff surface 4a of the left and right side plates 4. It is provided so as to be smaller than the in-width dimension between the side surfaces 7a of the notched step portion 7 formed. Further, the height dimension of the back plate 6 (the height dimension when the upper and lower end surfaces of the divided back plates are brought into contact with each other in the case of the divided back plate divided into the upper and lower sides) is the cuff surface 2a on the back side of the top plate 2. And the bottom surface 3a of the bottom plate 3 are provided so as to be smaller than the height dimension between the side surfaces 7a of the notch step portion 7 provided on the bottom surface 3a.

  Moreover, the groove shape of the said groove | channel J as a backplate attachment position identification display provided in the back surface of the backplate 6 is a cross-sectional view substantially V-shaped groove | channel. The thickness dimension of the back plate 6 is usually about 3 to 9 mm. The depth dimension of the groove J is preferably about 10 to 30% of the thickness dimension of the back plate 6 for the nailing workability, the finished quality, and the strength of the back plate itself. For example, when the thickness of the back plate 6 is about 3 mm, the depth dimension of the groove J is preferably about 0.3 to 1.0 mm. If the depth is less than about 0.3 mm, the groove J is difficult to identify, and the tip of the nail may slip, and if it is deeper than about 1.0 mm, the strength of the back plate 6 is marked at the position of the groove J. It will drop and cause damage. Further, when the thickness of the back plate 6 is relatively thick, such as about 4 to 9 mm, it may be a little deeper. Further, the width dimension of the groove J needs to be conspicuous as an identification display, and is preferably about twice the depth of the groove as one guideline.

  Moreover, the cross-sectional shape of the groove J in the second embodiment of the present invention is substantially V-shaped. Therefore, assuming that the thickness dimension of the back plate 6 is usually about 3 to 9 mm, the groove width of the substantially V-shaped groove in cross section is about 0.6 to 6.0 mm, and the groove depth is about 0.3 to About 3.0 mm is preferable. When the thickness of the back plate 6 is 3 mm, the groove width of the substantially V-shaped groove in cross section is preferably about 0.6 to 2.0 mm, and the groove depth is preferably about 0.3 to 1.0 mm. .

  The groove opening angle of the V-shaped groove J in the cross-sectional view is preferably about 45 to 120 degrees. If the angle is more acute than about 45 degrees, the bottom of the groove is too sharp, and the back plate 6 may be damaged at that point. In addition, in the case of an obtuse angle than about 120 degrees, there is a risk that the identification becomes slightly unclear visually. Further, the tip of the nail N or the like becomes slippery. The groove opening angle of the groove J is optimally about 90 degrees.

  According to the back plate mounting structure shown in the second embodiment of the present invention, the notch step portion 7 for fitting the back plate 6 to the left and right side plates 4 is provided, and when the back plate 6 is attached to the notch step portion 7, In particular, when attaching a nail or a wood screw or the like by slanting, the workability is better when nail-attached using the nail N than when screwed with a wood screw. Further, when the groove J as the back plate mounting position identification display M is a groove having a substantially V-shaped cross-sectional view, when the nail N is slanted in a diagonal direction, the groove of the groove having a V-shaped cross-sectional shape is used. The nail N is driven almost perpendicularly to the wall surface. Therefore, in this way, there is no damage to the nail N, and the diagonal driving of the nail N can be performed very easily with good workability, high accuracy, and good finish.

  The material of the box 1 and the structure of each member panel in the first and second embodiments of the present invention are preferably as follows. That is, the structure of each member panel such as the top plate 2, the base plate 3, the left and right side plates 4, and the partition plate 5 is a core material made by combining core materials made of wood materials such as plywood, LVL, and medium specific gravity fiber board vertically and horizontally. (Not shown), and a so-called flash structure panel in which a thin plywood having a thickness of about 3 to 6 mm and a medium specific gravity fiber board or the like are attached to both sides of the front and back surfaces is cost, workability, etc. To preferred. However, a panel having a solid structure other than a panel having a flash structure is of course good.

  As the material of the plywood and the like used for each member panel, for example, broad-leaved trees such as lauan, capol, joncon, and melapie, or conifers such as radiata pine and baituga are used. Moreover, the surface decorative material of the top plate 2, the base plate 3, and the left and right side plates 4 is, for example, a single plate or a veneer made of a natural wood having a thickness of about 0.2 to 1.0 mm, and a thickness of about 0.15 to about 0.15. Preferable examples include a PVC resin sheet of about 0.25 mm, a decorative resin sheet obtained by printing a wood pattern on an olefin resin sheet, and a decorative paper obtained by printing a wood pattern on a thin paper. The surface decorative material on the inner side of the left and right side plates 4, the partition plate 5, and the back plate 6 is, for example, a decorative paper in which a wood grain pattern is printed on a paper such as a thin paper, or a decorative paper in which a monochrome printing is applied. Etc. can be illustrated as a suitable thing.
