Description

  The present invention relates to an edge member mounting structure for a top plate to which an edge member for protecting an end surface of the top plate is attached, and a manufacturing method thereof.

  Conventionally, a technique for protecting an edge of a top plate by attaching an elastic edge member to the edge of the top plate such as a table is known. By attaching a long edge member extruded from plastic or other material into a uniform cross-sectional shape along the end of the top plate, the top plate is extended from the straight line to the corner. Can be protected. However, since the edge member is elastically deformed at the corner portion of the top plate and the cross-sectional shape is different from that of the straight portion, the shape of the surface of the edge member is changed and the boundary with the top plate is likely to be distorted.

  On the other hand, in the edge mounting structure of the top plate disclosed in Patent Document 1, a smooth surface shape is maintained even if the cross-sectional shape of the edge member changes in the corner portion. That is, according to the technique of Patent Document 1, as shown in FIG. 7A, which is a cross-sectional view showing the edge mounting structure, a long length that can be elastically deformed to the edge mounting portion 111 formed on the end surface 110 of the top plate 101. A shaped edge member 102 is attached. The edge member 102 is provided with edge forming surfaces 121 that can be connected to the upper and lower ends of the edge mounting portion 111, and the upper end portion 114 and the lower end portion 115 of the edge mounting portion 111 are elastically biased on the edge forming surface 121. Are provided with an upper pressing end 124 and a lower pressing end 125 which are continuous pressing ends. An upper and lower recess 126 is formed on the upper surface of the edge member 102, and an upper and lower space S 101 that is a deformation-permitting space is provided between the horizontal surface 106 of the edge mounting portion 111 and the edge member 102. Thereby, even if the cross-sectional shape of the corner portion 104 of the top plate changes from that of the straight portion 105, the edge member 102 is allowed to be deformed by the upper and lower spaces S101 as shown in FIG. 114 and the lower end portion 115 and the edge forming surface 121 have a smooth continuous appearance.

  However, in the edge mounting structure of Patent Document 1, the edge member 102 is formed in a uniform cross-sectional shape by extrusion molding or the like, and is deformed over the entire edge member 102 up to the portion attached to the straight portion 105 of the top plate 101. There was a gap in the allowable space. The edge member 102 that is in contact with the top plate 101 at the upper end portion 114 and has the upper and lower spaces S101 between the top plate 101 and the edge member 102 is thin, and the edge member 102 is aged over time due to long-term use. Since the deterioration is likely to cause deformation, the smooth continuity of the appearance of the top plate 101 and the edge member 102 may be impaired. Further, since the upper and lower spaces S101 are provided between the top plate 101 and the edge member 102, the edge member 102 is easily deformed when pressed, and the edge member 102 is soft to a person who touches the edge of the top plate 101. There was a risk of discomfort with a low-waist feeling.

  In addition, when the curvature varies depending on the corner, for example, when the top plate has a trapezoidal shape in plan view, since the amount of deformation of the edge member 102 increases as the corner has a larger curvature, the edge member 102 is adjusted to the corner having the largest curvature. There is a possibility that the deformation allowable space becomes larger than necessary at the straight portion 105 or a corner having a small curvature, and the above-described problem may be more likely to occur.

  Therefore, in view of the above situation, the present invention can prevent the appearance distortion of the edge member at the corner portion of the top plate and has a firm response when the edge member is pressed. An object of the present invention is to provide an edge member mounting structure for a top plate and a method for manufacturing the same.

  The top plate edge member mounting structure of the present invention has a structure in which "at least the side is open to the outer periphery of the top plate having a corner portion to which the edge member, which is a long elastic body having substantially the same cross-section, is mounted. An edge member mounting structure for a top plate for attaching the edge member to a groove-shaped edge member mounting portion having an upper contact surface on which an upper surface contacts and an inner contact surface on which a side surface of the edge member contacts, The edge member mounting portion includes a concave portion formed on the upper contact surface in the corner portion ”.

  Here, the “top plate” indicates a plate material constituting the upper surface of a table or a shelf, and the “edge member” indicates a member that is attached to the outer periphery of the top plate and protects the top plate. The “corner portion” indicates a curved portion in the plan view shape of the top plate, and the curvature thereof is not particularly limited. Further, the “end face” is a face on the outer periphery of the top plate and facing sideways.

  When the edge member, which is a long elastic body, is mounted on the outer periphery of the top plate, the side surface of the edge member contacts the inner contact surface of the edge member mounting portion at the corner portion, and tension is generated on the outer peripheral side of the edge member. Compression occurs on the inner peripheral side of the edge member. At this time, when the edge member is deformed, the upper surface of the edge member and the upper contact surface do not come into contact with each other cleanly, creating a gap between the edge member and the top plate, or the upper end of the outer peripheral surface of the edge member. There is a possibility that the aesthetic appearance of the top plate and the edge member may be impaired because the end surface of the top plate is displaced and does not match.

  On the other hand, according to the present invention, the concave portion is formed on the upper contact surface, and the upper end of the outer peripheral surface of the edge member is aligned with the end surface of the top plate when the edge member is attached. The bulge part which bulges on the upper surface of the edge member in the corner part of a top plate is received. Accordingly, the upper end of the outer peripheral surface of the edge member and the end surface of the top plate can be matched and firmly attached without causing a gap between the top plate and the edge member. Further, it is possible to prevent the appearance of the top plate and the edge member from being damaged due to the external distortion of the edge member.

  In addition, according to the present invention, almost no gap is generated between the top plate and the edge member including the corner portion, and the edge member abuts on the top plate on the upper surface and the side surface to exert a firm elasticity. It is possible to install as follows. When the body touches the edge of the top plate and presses the edge member, the edge member provides a feeling of elasticity with a waist, so that a good impression can be given.

  In addition, according to the present invention, it is not necessary to provide a space between the edge member and the edge member attachment portion, and the edge member can be firmly attached to the edge member attachment portion. It is also possible to form a relatively simple cross-sectional shape. Thereby, even when the material of the edge member changes over time and the dimensions are slightly deviated, it is possible to prevent the occurrence of large deformation and breakage and maintain the aesthetic appearance. Further, since the gap between the edge member and the edge member attachment portion is small and can be firmly brought into contact, it is suitable when the edge member is adhered to the edge member attachment portion using an adhesive.

  Moreover, the edge member attachment structure of the top plate of this invention can also be set as the structure "The said edge member attachment part is continuously formed over the perimeter of the said top plate."

  According to this configuration, although the shape of the bulging portion differs depending on the curvature at the corner portion of the top plate, the concave portion is formed in a shape that accepts the bulging portion, so the corner having different curvatures. The edge member can also be attached to the entire periphery of the top plate along the outer periphery along the outer periphery, with the outer appearance of the edge member kept uniform in the part and the straight part. Thereby, it is possible to prevent the disturbance of the appearance over the entire circumference of the top plate and finish the entire edge member to a uniform appearance.

  In addition, the edge member mounting structure of the top plate of the present invention has a structure in which "at least the side is open to the outer periphery of the top plate having a corner portion to which the edge member that is a long elastic body having substantially the same cross section is attached, Manufacture of an edge member mounting structure for a top plate in which the edge member is attached to an edge member mounting portion formed in a groove shape having an upper contact surface with which the upper surface of the member contacts and an inner contact surface with which the side surface of the edge member contacts. In the method, the paint is attached to the upper surface of the edge member, the temporary assembly step of temporarily attaching the edge member to the edge member attaching portion, and the temporarily attached edge member including at least the corner portion Pressing toward the inner peripheral side to match the upper end of the outer peripheral surface of the edge member and the end surface of the top plate, and the shape of the portion pressed against the upper contact surface of the edge member by the paint Ink that is transferred to the upper abutment surface to form inking And a cutting step of removing the edge member and forming a concave portion for receiving a bulging portion bulging on the upper surface of the edge member based on the marking. It is possible to manufacture.

  Here, “temporary attachment” indicates that the member is attached in a detachable state. That is, when the edge member is attached to the edge member attaching portion, it is originally attached by using an adhesive or the like to prevent dropping, but in the temporary attachment, the edge member is attached so that it can be removed later. For example, a method can be shown in which an edge member is attached to the edge member attaching portion and is attached and fixed with an adhesive tape. The method for fixing the edge member is not particularly limited, and may be an obstacle to the marking process and the cutting process.

  According to this structure, the groove-shaped edge member attaching part which can attach the edge member which is a long elastic member is formed in the outer periphery of a top plate first. And the edge member which made the paint adhere to the upper surface by a temporary assembly process is temporarily attached to an edge member attaching part. Thereafter, the edge member is pressed toward the inner peripheral side so that the upper end of the outer peripheral surface of the edge member and the end surface of the top plate coincide with each other by the inking process, and the paint adhering to the upper surface of the edge member is removed. It is transferred to the upper abutment surface to form a sacrificial portion where the edge member abuts. Then, the shape of the concave portion to be formed is determined based on the marking by the cutting process, and is formed by cutting or the like.

  In the marking process, by pressing the edge member toward the inner peripheral side around the corner portion, the internal pressure of the edge member increases and the upper surface of the edge member tends to bulge upward. Press. At this time, depending on the strength with which the upper contact surface is pressed, a difference occurs in the state of the paint on the upper contact surface, and the marking indicating the shape of the portion pressed by the upper surface of the edge member can be formed. . Thereby, the marking can be easily formed only by matching the outer peripheral surface of the temporarily attached edge member with the end surface of the top plate. According to the present invention, the inking process corresponding to the shape of the bulging part of the edge member is formed by the inking process, so that it is possible to easily form the concave part without requiring precise measurement and design. Become. Even when the shape such as the curvature of the corner portion is different, the same operation may be performed, and the various products having the corner portion having different shapes can be similarly marked. At this time, since special equipment, tools, and skill of the operator are not required, the manufacturing cost can be reduced.

  In forming the concave portion, it is possible to derive the exact shape of the bulging portion of the edge member by calculation by computer simulation or the like, but a program or operation for simulation is required. On the other hand, according to this configuration, an appropriate shape of the concave portion can be easily determined by the marking process. In addition, since no special measuring instrument or system is required, the manufacturing cost can be reduced.

  As a method of forming the concave portion, for example, a method of forming using a general cutting tool such as a file or a cutter can be shown. Since the edge member attaching portion has a recessed shape, a method of cutting using a small electric hand tool such as an electric router is suitable.

  In the case of a wet type, the “paint” may be dried before the temporary assembly process and the inking process are completed, or may not chemically damage the surface when adhering to the edge member and the edge member mounting portion. Although it is desirable, the type is not particularly limited, and various types such as ink, paint, water-based paint, and oil-based paint can be used. Moreover, it is not limited to a wet type, a dry type may be sufficient and a powdered pigment etc. may be sufficient. In addition, in order to create a clear ink marking between the part where the paint is attached and the part where the paint is not attached, it is necessary that the paint is attached in a state where it is spread evenly at least at the part corresponding to the corner part of the top plate. There is.

  Further, the manufacturing method of the edge member mounting structure of the top plate according to the present invention is as follows: “At least the side is opened to the outer periphery of the top plate having a corner portion to which the edge member, which is a long elastic body having substantially the same cross section, is attached. An edge member mounting of a top plate for attaching the edge member to a groove-shaped edge member mounting portion having an upper contact surface with which the upper surface of the edge member contacts and an inner contact surface with which the side surface of the edge member contacts A method for manufacturing a structure, comprising: attaching a sheet having a paint surface to an upper surface of the edge member; temporarily attaching the edge member to the edge member attaching portion; and temporarily attaching the edge member. At least in the range including the corner portion, it was pressed toward the inner peripheral side, the upper end portion of the outer peripheral surface of the edge member was matched with the end surface of the top plate, and was pressed by the upper contact surface of the edge member The shape of the part is changed to the upper side by the paint on the paint surface. An inking process for forming inking by transferring to the contact surface, and a step of removing the edge member and forming a recessed portion for receiving the bulging portion bulging on the upper surface of the edge member based on the inking. It is also possible to adopt a configuration in which the cutting process is performed in order.

  Here, the “sheet” is not particularly limited as long as it is a thin paper and can be attached to the upper surface of the edge member. For example, it may be made of plastic such as vinyl chloride, or may be made of paper, but if it has hygroscopicity, it will be inked with a larger amount of paint than impregnating the paint and attaching it to the surface. Can be used for Moreover, it may have a texture with a fine undulation that holds the paint on the surface, such as one made of a fibrous material, and is more desirable to be familiar with the paint used. “Paint surface” indicates a surface having a paint. The paint may be attached in advance before the sheet is attached, or the paint surface may be provided after the sheet is attached.

  According to this configuration, the paint is not directly attached to the upper surface of the edge member, but the sheet to which the paint is attached is attached to the upper surface of the edge member, so that the paint is not directly attached to the upper surface of the edge member. be able to. If the paint does not adhere to the upper surface of the edge member in the marking process, the need to clean the edge member can be eliminated. Further, since the paint can be removed by peeling off the sheet, the labor of the manufacturing process can be saved. In addition, when the upper surface of the edge member is finished smoothly, there is a risk that when the paint is applied directly to the upper surface of the edge member, it becomes water droplets and does not spread uniformly and the inking is not clear. On the other hand, the paint can be uniformly adhered by using a sheet that is easily compatible with the paint to be used.

  Using a sheet made of a hygroscopic material allows the paint to be contained abundantly, so that when the edge member is pressed during the inking process, it is easy to cause shade in the state of adhesion of the paint to the upper contact surface. The shape of the concave portion can be easily determined in the cutting process.

  As described above, according to the present invention, it is possible to prevent the appearance distortion of the edge member at the corner portion of the top plate and to have a firm response when the edge member is pressed. It is possible to provide an edge member mounting structure for a top plate and a method for manufacturing the same.

  Hereinafter, the structure of the edge member attachment structure 8 of the top plate 1 which is one Embodiment of this invention is demonstrated based on FIG. 1 thru | or FIG. FIG. 1 is a perspective view showing a table having a top plate edge member mounting structure according to an embodiment of the present invention, and FIG. 2A is a cross-sectional view showing a top plate edge member mounting structure in a straight portion. FIG. 2B is a cross-sectional view showing the top member mounting structure of the top plate at the corner, and FIG. 3A is a perspective view showing the top member mounting structure of the top plate. 3 (b) is a bottom view showing the edge member mounting structure of the top plate.

  Hereinafter, the structure of the top plate 1 will be described in detail with reference to FIGS. 1 to 3. As shown in FIG. 1, the top plate 1 is a plate material that has a substantially rectangular planar shape with rounded corner portions 4 and constitutes a horizontal table surface S of the table T. A leg portion L that supports the top plate 1 is attached to the lower surface of the top plate 1. An edge member 2 is attached to the outer periphery 3 of the top plate 1 over the entire periphery including the corner portion 4 and the straight portion 5 of the top plate 1.

  As shown in FIGS. 1 to 3, a groove-like edge member mounting portion 10 is continuously provided on the outer periphery 3 of the top plate 1 over the entire periphery. The edge member 2 is a long elastic body having an edge member outer peripheral surface 24, an edge member inner peripheral surface 21, an edge member upper surface 22, and an edge member bottom surface 26. is there. The edge member inner peripheral surface 21 and the edge member upper surface 22 are substantially perpendicular to each other with the ridge line 23 interposed therebetween. In terms of the positional relationship when the edge member 2 is attached to the top plate 1, the edge member inner peripheral surface 21 is an upright surface, and the edge member upper surface 22 is a flat surface. The edge member outer peripheral surface 24 is a substantially arc surface, and the lower end portion of the edge member outer peripheral surface 24 has a lower inner peripheral surface 27 extending below the edge member bottom surface 26, and the cross-sectional shape of the lower end portion of the edge member 2 Has a wedge shape protruding downward. When the edge member 2 is attached to the top plate 1, the side of the edge member attachment portion 10 is closed, and the edge member outer peripheral surface 24 is continuous with the top plate upper end surface 31 and the top plate lower end surface 32 and uniformly over the entire periphery. It exhibits a smooth shape such that the lower corner of the outer periphery 3 is rounded and chamfered. The edge member 2 can be elastically deformed, and can be wound around and attached to a curved portion such as the corner portion 4 of the top plate 1 as described above. When the edge member 2 is curved, the inner peripheral side of the curved portion is compressed and the outer peripheral side is expanded. Then, swelling occurs on the inner peripheral side to be compressed. Here, the edge member inner peripheral surface 21 corresponds to the side surface of the edge member of the present invention, the edge member upper surface 22 corresponds to the upper surface of the edge member of the present invention, and the edge member outer peripheral surface 24 corresponds to the edge of the present invention. It corresponds to the outer peripheral surface of the member.

  The edge member mounting portion 10 provided on the outer periphery 3 has a shape in which the lower portion of the outer periphery 3 of the top plate 1 is cut out into a groove shape having a substantially “U” -shaped cross section. As shown in FIG. 2, in the straight portion 5 of the top plate 1, an inner contact surface 11 forming an upright surface, an upper contact surface 12 forming an upper horizontal surface, a bottom contact surface 16 forming a lower horizontal surface, and a bottom portion It is constituted by a lower side surface 17 that forms a vertical surface extending downward from the end of the contact surface 16. Further, as shown in FIG. 2 (b), in the corner portion 4 of the top plate 1, in addition to the inner contact surface 11, the upper contact surface 12, the bottom contact surface 16 and the lower surface 17, the upper contact A concave portion 15 provided in a concave shape on the contact surface 12 is provided. The entire inner contact surface 11 is continuous from the straight portion 5 to the corner portion 4 along the outer periphery 3 and has an endless belt shape.

  As shown in FIGS. 3 (a) and 3 (b), the concave portion 15 is in the shape of an arc or “U” with a curvature corresponding to the shape of the corner portion 4, and gradually from both ends to the center portion. It is a depression provided on the upper contact surface 12 of the edge member mounting portion 10 with a thickened shape. The upper contact surface 12 faces downward, and the concave portion 15 is a groove shape having a mountain-shaped cross section that is depressed upward, and the depression gradually becomes deeper from both ends of the plan view shape to the central portion. The concave portion 15 is formed in a shape that matches the bulging portion 25 in which the edge member upper surface 22 of the edge member 2 bulges upward, that is, toward the upper contact surface 12 in the corner portion 4.

  Thus, by providing the edge member mounting portion 10 with the inner abutment surface 11, the upper abutment surface 12, the bottom abutment surface 16, the lower side surface 17, and the concave portion 15 provided in the corner portion 4, A plate edge member mounting structure 8 is configured.

  As shown in FIGS. 2A and 2B, the edge member 2 has the edge member outer peripheral surface 24 aligned with the top plate upper end surface 31 and the top plate lower end surface 32, and the edge member mounting portion 10 of the top plate 1. Is adhered to. As the edge member 2 is wound along the outer periphery of the top plate 1, the edge member inner peripheral surface 21 is pressed against and closely contacts the inner contact surface 11. As shown in FIG. 2A, in the straight line portion 5, the upper surface 22 of the edge member facing upward is in contact with the smooth upper contact surface 12 facing downward in the horizontal direction. The edge member outer peripheral surface 24 of the edge member 2 is smoothly connected to the top plate upper end surface 31. As shown in FIGS. 2B, 3 </ b> A, and 3 </ b> B, also in the corner portion 4, the upper end portion 18 of the edge member outer peripheral surface 24 matches the top plate upper end surface 31 of the top plate 1. The bulging portion 25 generated on the upper surface 22 of the edge member due to the compression of the inner peripheral side of the edge member 2 is received by the concave portion 15 formed on the upper contact surface 12, and the corner portion 4 is also the same as the straight portion 5. The edge member attaching portion 10 and the edge member 2 are in close contact with each other. Further, the lower end portion 19 of the edge member outer peripheral surface 24 coincides with the top plate lower end surface 32 located at the lower portion of the outer periphery 3 of the top plate 1. In this way, the edge member 2 and the edge member mounting portion 10 are bonded in close contact with each other over the entire periphery of the top plate 1, and the edge member outer peripheral surface 24 is smoothly continuous with the outer surface of the top plate 1. Here, the top plate upper end surface 31 corresponds to the end surface of the present invention.

  Hereinafter, based on FIG. 4 and FIG. 5, the manufacturing method of the edge member attachment structure of the top plate which is one Embodiment of this invention is demonstrated in detail. 4 (a), 4 (b), and 4 (c) are explanatory views showing a marking process for determining the shape of the concave portion 15, and FIG. 5 (d) is a concave shape cut by marking. FIG. 5E is a diagram illustrating a cutting process for forming the portion 15, and FIG. 5E is a cross-sectional view of the top plate 1 that has been marked with a horizontal position corresponding to the line AA illustrated in FIG. It is explanatory drawing shown and demonstrated.

  In this embodiment, although illustration of a process is abbreviate | omitted first, the outer periphery 3 of the top plate 1 is cut in a groove part formation process, and the groove part 10a is formed continuously over the perimeter of the top board 1. FIG. As shown in FIG. 2A, the groove portion 10 a is formed in a groove shape that is open on the side and has an inner contact surface 11, an upper contact surface 12, a bottom contact surface 16, and a lower surface 17. Yes. The upper contact surface 12 is formed as a uniformly flat surface over the straight portion 5 and the corner portion 4. Here, the groove 10a corresponds to the edge member mounting portion of the present invention.

  Subsequently, as shown in FIG. 4A, the paint 52 is uniformly attached to the edge member upper surface 22, and the edge member 2 is temporarily attached to the groove portion 10a (temporary assembly process). Temporary attachment means attaching a member in a detachable state, and does not firmly bond the edge member 2 to the groove portion 10a with an adhesive or the like, but temporarily attaches it with an adhesive tape or the like. At this time, first, temporary attachment of the edge member 2 to any one corner portion 4 of the top plate 1 is started. The concave portion 15 is formed around the corner portion 4, and a clear inking 51 is required in the corner portion 4, so that the work in the corner portion 4 is given priority over the straight portion 5. In order to prevent the edge member 2 from falling off from the groove 10a, the work is carried out while being fixed with an adhesive tape (not shown) as needed, and the edge member 2 moves carelessly and rubs against the upper abutment surface 12 to make the inking 51 unclear. Do not become.

  In the marking process, as shown in FIG. 4B, the edge member 2 in which the upper end 18 protrudes from the top plate upper end surface 31 and is temporarily attached as the corner 4 is curved is replaced with the edge member 2 shown in FIG. As shown in c), the roller R is pressed from the side, the bulging portion 25 is led out so as to rise to the upper surface 22 of the edge member, and is transferred to the upper contact surface 12 to form the marking 51. When the markings 51 can be formed in all the corner portions 4, the adhesive tape is peeled off and the edge member 2 is carefully removed from the top plate 1 as shown in FIG.

  More specifically, when the upper end 18 of the edge member outer peripheral surface 24 is pressed by the roller R to match the top plate upper end face 31, the curved portion attached to the corner 4 of the edge member 2 is compressed. Thus, the edge member upper surface 22 is deformed into a shape bulging upward, and a bulging portion 25 having a mountain-shaped cross section is generated. The shape and size of the bulging portion 25 are determined according to the curvature and the central angle of the corner portion 4. The edge member 2 is more strongly curved as the curvature of the corner portion 4 is larger. The planar shape of the bulging portion 25 also has a high curvature and a large curvature. Moreover, since the compression rate of the inner peripheral side of the edge member 2 becomes high, the swelling of the bulging part 25 which arises when it presses becomes large. As shown in FIG. 5 (e), the finished inking 51 has a shape in which the paint 52 is attached in an arc shape or “character shape” that gradually increases from both ends to the center.

  Then, in the cutting process, the concave portion 15 is formed by cutting the back portion 12 a (see FIG. 2B) of the upper contact surface 12 based on the marking 51. As a method for forming the concave portion 15, cutting is performed using a general cutting tool such as an electric router, a file, and other blades. Since the edge member upper surface 22 is in contact with the upper abutting surface 12 for the portion of the inking 51 where the inked ink is attached, electric power is applied from the end of the inking 51 formed in an arc shape or a square shape. The concave portion 15 is formed into a valley shape corresponding to the bulging portion 25 by cutting with a router. About the depth of the recessed part 15, it can determine by measuring the height dimension at the time of the bending of the edge member 2 with a caliper etc. previously. Since there is a possibility that the shape of the marking 51 where the edge member 2 is attached at the beginning of the temporary assembling process may be inaccurate, it is processed last in alignment with the shape of other portions. Accordingly, the concave portion 15 is formed in a shape that can receive the bulging portion 25, the edge member attaching portion 10 is completed, and the edge member attaching structure 8 can be provided on the outer periphery 3 of the top plate 1.

  As described above, since the shape of the bulging portion 25 is determined by the curvature and the central angle of the corner portion 4, it is difficult to form the concave portion 15 in an optimal shape without forming the marking 51. In particular, when the corner portion 4 is formed in a shape whose curvature changes smoothly like a curve ruler, the shape of the bulging portion 25 becomes complicated. Even in such a case, according to the inking process of the present embodiment, the shape of the bulging portion 25 is copied to the upper abutment surface 12 to create the inking 51, so that it corresponds to the bulging portion 25. A concave portion 15 having a shape can be formed.

  Thus, according to the edge member mounting structure 8 of the top plate 1 which is an embodiment of the present invention, the concave portion 15 formed on the upper contact surface 12 is pressed by the edge member 2 curved at the corner portion 4. Accordingly, in order to receive the bulging portion 25 in conformity with the bulging portion 25 bulging from the upper surface 22 of the edge member, it is possible to securely attach without causing a gap between the top plate 1 and the edge member 2. Is possible. Moreover, since the recessed part 15 receives the bulging part 25, deformation | transformation of the edge member 2 in the corner part 4 is prevented, there exists a possibility that the appearance of the top plate 1 and the edge member 2 may be impaired because the edge member 2 exhibits the distorted external appearance. Can be prevented.

  Further, according to the edge member mounting structure 8 of the top plate 1 of the present embodiment, the edge member 2 is attached to the top plate 1 with almost no gap including the corner portion 4, and the edge member 2 is It is possible to exert a firm elasticity. When the body touches the edge of the top plate 1 and presses the edge member 2, the edge member 2 provides a resilient feeling with a waist, so that a good impression can be given.

  Furthermore, according to the edge member attachment structure 8 of the top plate 1 of the present embodiment, the edge member 2 can be firmly attached to the edge member attachment portion 10, and the material of the edge member 2 changes over time. Even when the dimensions are slightly out of order, it is possible to prevent the occurrence of large deformation and breakage and maintain the aesthetics.

In this case, the bonding surface becomes a three-dimensional shape, and the upper surface 22 of the edge member and the upper contact surface 12 are firmly bonded to each other, so that excellent bonding strength can be obtained.

  Furthermore, according to the edge member mounting structure 8 of the top plate 1 of the present embodiment, if the shape and material of the edge member 2 are the same, the bulging portion 25 and the concave shape according to the curvature and the center angle of the corner portion 4. The shape of the part 15 is determined. In other words, since the shape of the concave portion 15 may be determined according to the curvature and the center angle of the corner portion 4, the edge member 2 can be a common member among various products. Further, if the curvature and the central angle of the corner portion 4 are the same, the shape of the concave portion 15 is also the same, and the shape can be easily determined. Thereby, it is possible to reduce the cost of design and manufacture.

  Furthermore, according to the edge member mounting structure 8 of the top plate 1 of the present embodiment, the edge member 2 can be attached in a uniform shape along the outer periphery 3 over the entire periphery of the top plate 1 and is uniformly arranged. An appearance can be exhibited. In the corner portion 4 of the top plate 1, a concave portion 15 is formed on the upper contact surface 12 in accordance with the shape of the bulging portion 25 generated on the edge member upper surface 22 of the edge member 2. By accepting, the appearance of the edge member 2 is prevented from being disturbed in shape, and the edge member 2 at the corner portion 4 exhibits the same appearance as the straight portion 5 and other corner portions 4 having different curvatures. As a result, the edge member 2 can be finished to have a uniform appearance as a whole.

  Moreover, according to the edge member attachment structure 8 of the top plate 1 of this embodiment, the edge member 2 is temporarily attached to the groove portion 10a, and from the side so that the upper end portion 18 and the top plate upper end surface 31 coincide. In the marking process, the marking part 51 is formed on the upper contact surface 12 by the marking process, and the concave part 15 is formed based on the marking process 51 in the cutting process. Does not require precise measurement or work, and the marking 51 can be easily formed by pressing the temporarily assembled edge member 2.

  Moreover, according to the manufacturing method of the edge member attachment structure 8 of the top plate 1 of this embodiment, the suitable shape of the concave-shaped part 15 can be determined easily by a marking process. For example, it is possible to derive an accurate shape of the bulging portion 25 of the edge member 2 by calculation by computer simulation or the like, but a program or operation for simulation is required. On the other hand, in the present embodiment, the shape of the concave portion 15 can be determined in a short time by a simpler method. Moreover, according to the manufacturing method of the edge member attachment structure 8 of the top plate of this embodiment, since a special measuring instrument and system are not required, manufacturing cost can be reduced.

  Moreover, according to the manufacturing method of the edge member attachment structure 8 of the top plate 1 of this embodiment, since the recessed part 15 is formed in the upper side contact surface 12, it is an edge member toward the inner peripheral side in the marking process. When the pressure 2 is pressed, the ink 52 can be clearly formed without causing the paint 52 to adhere to an extra portion. If the concave portion 15 is formed on the inner contact surface 11, the edge member inner peripheral surface 21 is generally pressed against the inner contact surface 11 when the edge member 2 is inserted into the groove 10a. Therefore, there is a possibility that the paint 52 may adhere to an unnecessary portion and the inking 51 may be unclear. However, in this embodiment, since the concave portion 15 is provided on the upper contact surface 12, the edge member The temporary assembly process and the inking process may be performed by attaching the paint 52 to the upper surface 22, and it is possible to prevent a problem that the paint 52 is widely attached to unnecessary portions when the edge member 2 is inserted into the groove 10 a. it can.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the above-described embodiment, the manufacturing method for forming the concave portion 15 by performing the temporary assembly process, the inking process, and the cutting process once is shown, but the present invention is not limited thereto, and the concave section is not limited thereto. In order to confirm the depth of the dent 15, the shape of the concave portion 15 may be corrected by temporarily attaching it again and marking it. Further, the processing accuracy may be gradually increased by repeating the temporary assembly process to the cutting process over a plurality of times.

  Further, the depth of the recess of the recessed portion 15 may be formed slightly larger than the height of the bulging portion 25. When the depth of the recess of the concave portion 15 is larger than the height of the bulging portion 25, more adhesive is attached to the concave portion 15 when bonding with an adhesive, and the adhesive is more firmly bonded after drying. Can be done.

  In the above embodiment, the cross-sectional shape of the edge member 2 is a shape obtained by rounding one corner of the rectangle. However, the cross-sectional shape is not limited to this, and the cross-section may have another shape. The cross sectional shapes of the inner contact surface 11 and the upper contact surface 12 may be different. For example, a protruding portion having a ridge shape is provided from the inner peripheral surface 21 of the edge member toward the inner peripheral side, and the inner contact surface 11 has a cross-sectional shape having a recess that constitutes a groove that matches the protruding portion. Things can be shown.

  In the above-described embodiment, the groove forming step is shown as the groove forming step. However, the present invention is not limited to this. For example, the top plate 1 is manufactured by stacking a plurality of plate members. The groove portion 10a may be formed on the outer periphery 3 in a terrace shape depending on the shape of the plate material forming the top plate 1. Moreover, when the top plate 1 is formed of metal or plastic, the groove portion 10a may be formed by other processing methods such as press processing.

  In the above-described embodiment, the ink 52 is used as the paint 52 for the ink marking 51. However, the present invention is not limited to this, and various paints can be used. When the material of the edge member 2 is plastic or rubber, it is preferable to use a water-soluble paint such as a watercolor paint rather than an organic solvent-based paint that roughens the surface of the edge member 2. Water-soluble paints, including ink, can be easily removed by washing or wiping after the inking process is completed, thus saving labor. Moreover, it is not necessary to limit to wet, and dry powder pigments, such as chalk and carbon, etc. may be sufficient. When wet paint is used, workability is reduced if it is dried before the temporary assembly process and the inking process are completed. Therefore, it is desirable to use a paint that can take sufficient working time without being dried. .

  Further, as shown in FIG. 6, the inking process may use a sheet 53 having a paint surface with paint on the surface. The sheet 53 is preferably hygroscopic paper or fibrous thin paper, but may be paper having a glossy surface coated with plastic or a plastic material. When the edge member 2 is formed of plastic or rubber, which is a material that can be elastically deformed, even if the paint is directly applied to the edge member 2, the paint does not spread evenly and tends to form water droplets, thus causing unevenness. On the other hand, by sticking the sheet 53 to the edge member upper surface 22 of the edge member 2, the paint can be easily extended uniformly, and the shape of the inking 51 can be made clearer. Further, when a sheet 53 made of a hygroscopic material is used, the paint 52 is infiltrated into the sheet 53 and used, so that the paint is released according to the pressure applied to the sheet 53, and the clear and light inking is done. Can be formed. After the inking process is completed, the sheet 53 is removed together with the edge member 2 and removed from the edge member 2. In addition, a paint may be attached in advance before the sheet 53 is attached, or a paint surface may be provided after the sheet 53 is attached. In the case of using the sheet 53 to which the paint is previously attached, for example, a ready-made product such as carbon transfer paper can be processed and used as the sheet 53.

  In addition, when the sheet 53 made of a hygroscopic material such as a fiber is used, the paint 52 can be included in abundantly, so that the paint on the upper contact surface 12 when the edge member 2 is pressed in the inking process. It is easy to cause the adhesion state of 52 to be light and dark, and it is possible to easily determine the shape of the concave portion 15 in the cutting process. Even if it is a material with low hygroscopicity, if it has a texture with fine undulations on its surface, more paint can be applied while suppressing the possibility of the paint becoming water droplets due to surface tension.

  In the above embodiment, the method for obtaining the height dimension of the bulging portion 25 in advance in forming the concave portion 15 in the cutting process based on the marking is shown, but the present invention is not limited to this. The work from the marking process to the cutting process may be repeated a plurality of times without being completed once.

  In the above embodiment, the edge member 2 is pressed using the roller R. However, the present invention is not limited to this. For example, the edge member 2 may be pressed with a valen-like tool used in a print. It is also possible to press using other tools and devices. Moreover, the temporary assembly process and the inking process may not be clearly separated. For example, the inking process may proceed while the edge member 2 is attached in the temporary assembly process.

  When mass production of the top plate provided with the edge member mounting structure 8 of the present embodiment, the concave portion 15 formed by the above manufacturing method is measured and measured by a three-dimensional object scanning device or the like to collect shape data. However, it is also possible to perform processing using an NC processing machine based on the data.

  When a prototype is manufactured by the manufacturing method of the present embodiment for mass production of the edge member mounting structure 8 of the top plate, a plurality of corner portions 4 having the same curvature and angle are printed at one of them. The dimensions and shape of the concave portion 15 can be determined only by performing the attaching step and the cutting step, and the other corner portions 4 can be omitted.
