  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out a plate material joining structure according to the present invention will be described below based on examples.

  An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1A is an exploded perspective view showing a cabinet to which a plate material joining structure in Embodiment 1 is applied, and FIG. 2A is a perspective view of the joining clip in FIG. 1, FIG. 2A is a transverse plan view showing the joining clip, the side plate, and the back plate in Example 1, and FIG. 2B is the attachment of the joining clip to the side plate. 2 (c) is a cross-sectional plan view showing the side plate and the back plate after joining, and FIG. 3 (a) is a cross-sectional view showing the joining clip and side plate in the first embodiment. FIG. 3B is a transverse plan view showing the back plate, and FIG. 3B is a transverse plan view showing the side plate and the back plate after joining. Hereinafter, the lower side of the drawing in FIGS. 2 and 3 will be described as the front side of the cabinet.

  FIG. 1A shows a cabinet 1 that constitutes a sink and a cooking table arranged in a kitchen or the like. This cabinet 1 is made of stainless steel (thickness of about 0.4 mm in this embodiment). The side plates 2, the back plate 3, the bottom plate 4, the curtain plate 5, and the top plate (not shown) made of the above plate materials are joined together to be assembled. Further, at each end edge of the side plate 2, the back plate 3, the bottom plate 4, the curtain plate 5, and the top plate (not shown), a joining end portion 6 in which the edge portion of the plate material is bent into a substantially U-shape. 7, 8, and 9 are formed. In addition, the thickness of the plate material is not limited to the above-described about 0.4 mm, and can be variously changed.

  As shown in the partially enlarged view of FIG. 1A, circular holes 10 and 11 are formed through the joint end portions 6 and 7, respectively. A joining clip 12 as a connecting tool shown in FIG. 1B is inserted into the holes 10 and 11, and the joining plate 12 is inserted into the holes 10 and 11, whereby the side plate 2. The end edges of the back plate 3, the bottom plate 4, the curtain plate 5, and the top plate (not shown) can be joined together.

  Next, the joining structure of the board | plate material using the joining clip 12 is demonstrated to joining the side board 2 and the back board 3 as an example. As shown in FIG. 2A, the joining end portions 6 and 7 of the side plate 2 and the back plate 3 are bent at right angles from the plate material T and the plate material T by bending the end portions of the plate material T. The bent piece K1 and the second bent piece K2 bent at a right angle from the end of the first bent piece and parallel to the plate material T are formed in a substantially U shape in plan view. Holes 10 and 11 having the same diameter are formed in the plate material T of the side plate 2 and the first bent piece K1 of the back plate 3, that is, the joint surfaces 6a and 7a facing each other.

  Further, as shown in FIG. 2A, a through hole 13 is formed in the second bent piece K <b> 2 of the side plate 2. The through-hole 13 has a larger diameter than the holes 10 and 11 formed in the side plate 2 and the back plate 3 so that a later-described joining clip 12 can be inserted. Moreover, the 1st bending piece K1 and the 2nd bending piece K2 in the joining end part 6 are slightly formed rather than the front-back length and diameter of the holding part 15 of the joining clip 12 mentioned later.

  Next, the joining clip 12 will be described in detail. In addition, about the joining clip 12, an engaging direction is demonstrated as a front side. As shown in FIGS. 1B and 2A, the joining clip 12 is made of a material such as synthetic resin and is formed separately from the side plate 2 and the back plate 3, and formed on the joining surfaces 6a and 7a, respectively. The engaging portion 14 that can be inserted into the hole portions 10 and 11 and a columnar holding portion 15 having an outer diameter larger than the inner diameter of the hole portion 10 are mainly configured. The engaging portion includes a central shaft portion 14a projecting from a front end surface of a cylindrical fitting portion 16 projecting from the front end surface of the holding portion 15, and a rear side (holding) from the head of the central shaft portion 14a. And a pair of engagement pieces 14b extending so as to gradually spread outward (toward the portion 15 side).

  The pair of engaging pieces 14b extending in a substantially umbrella shape from the distal end portion of the central shaft portion 14a is formed to be elastically deformable, and the end portion with respect to the central shaft portion 14a side is centered on the central shaft portion 14a. Can be swung in a direction close to each other. Further, an engagement claw 14c extends inwardly (on the central shaft portion 14a side) at the end of the engagement piece 14b, and the end surfaces of the engagement piece 14b and the engagement claw 14c are engaged as described later. When the joint portion 14 is inserted into the holes 10 and 11, an engagement surface 14 d (see an enlarged view of FIG. 3B) that is engaged with the peripheral edge of the hole 10 is configured. Since the engaging surface 14d is a surface that faces in a direction substantially perpendicular to the longitudinal direction of the engaging piece 14b, the engaging surface 14d is inclined with respect to the plate material T when attached to the holes 10 and 11. It has become. Note that the distance L1 (see FIG. 1B) between the outer ends of the engaging pieces 14b extending from the central shaft portion 14a is based on the diameters of the holes 10 and 11 formed in the side plate 2 and the back plate 3. Is also formed long.

  On the other hand, the length of the holding portion 15 having a substantially cylindrical shape is substantially the same as the length from the hole portion 10 formed in the joining end portion 6 of the side plate 2 to the through hole 13. The fitting portion 16 is formed so that the outer diameter thereof is substantially the same as the inner diameter of the holes 10 and 11 formed in the side plate 2 and the back plate 3. Moreover, as shown in FIG.1 (b), the ring-shaped packing 17 (elastic member) formed with materials, such as soft rubber, is attached to the outer periphery of the fitting part 16. FIG.

  The joining structure and joining method of the side plate 2 and the back plate 3 using the joining clip 12 in Example 1 will be described. First, as shown in FIG. 2A, the engaging portion 14 and the fitting portion 16 of the joining clip 12 are inserted into the through hole 13 from the outside of the joining end portion 6 and further inserted into the hole portion 10 of the side plate 2. To do. Then, each of the pair of engaging pieces 14b is elastically deformed toward the central shaft portion 14a when passing through the hole 10 (see FIG. 2 (b) two-dot chain line), and the end of the engaging piece 14b is When coming out of the hole 10, the engagement piece 14 b spreads outward due to the elastic restoring force. Thus, the plate material T is sandwiched between the engagement surface 14d of the engagement piece 14b and the holding portion 15, and the joining clip 12 is held and attached to the hole portion 10 of the side plate 2 (see FIG. 2B). ).

  Next, with the joining clip 12 attached to the hole 10 of the side plate 2, the side plate 2 is brought close to the back plate 3, and the head of the engaging portion 14 of the joining clip 12 is inserted into the hole 11 of the back plate 3. . At this time, the operator joins the side plate 2 and the back plate 3 while pressing the rear end surface 15 a of the holding portion 15 of the joining clip 12 from the through hole 13.

  When the engaging portion 14 of the joining clip 12 in FIG. 2B is inserted into the hole 11 of the back plate 3, each of the pair of engaging pieces 14 b passes toward the central shaft portion 14 a when passing through the hole 11. 2 (refer to the two-dot chain line in the figure), and as shown in FIG. 2C, when the end of the engagement piece 14b comes out of the hole 11, the engagement piece 14b Spread outward.

  When the engaging piece 14b spreads outward, a part of the engaging surface 14d is engaged with the outer peripheral edge of the hole 11 of the back plate 3 as shown in the partially enlarged view (see) of FIG. Combined. In this engaged state, the engaging surface 14d is inclined obliquely with respect to the plate material T, and the tip of the engaging piece 14b, that is, the tip of the engaging claw 14c enters the hole 11. Become. Specifically, since the length dimension of the fitting portion 16 is formed to be slightly shorter than the total thickness of the plate material T of the side plate 2 and the thickness of the plate material T of the back plate 3, the engagement claw A gap L <b> 2 having a predetermined dimension into which the end of 14 c enters is formed in the hole 11 of the back plate 3.

  In this way, the engagement surface 14d is engaged with the peripheral edge of the hole portion 11, so that both plate materials T of the side plate 2 and the back plate 3 are sandwiched between the engagement surface 14d and the holding portion 15 and the side plate 2 The back plate 3 is joined. In addition, both plate members T are strongly pressed toward the holding portion 15 by the elastic restoring force that the engagement piece 14b tries to spread outward, and the outer peripheral edge of the hole portion 11 is moved outwardly from the inside by the engagement surface 14d. Since the positional displacement of the plate material T in the direction of the joining surfaces 6a and 7a is restricted, rattling of the two plate materials T at the time of joining is effectively prevented.

  Furthermore, since the packing 17 which is an elastic member is provided between the plate material T of the side plate 2 and the front end surface of the holding portion 15, the action of pressing the holding portion 15 against the plate material T works. As a result, the engaging surface 14d is more strongly pressed against the peripheral edge of the hole 11, so that the separation of the two plate materials T is effectively prevented.

  Further, the engaging surface 14d is engaged with a part of the engaging surface 14d entering the hole 11, and the engaging surface 14d is elongated by the engaging claw 14c. Therefore, for example, even if an error occurs in the thickness of the plate member or the length of the engagement piece 14b of the joining clip 12 due to factors such as molding accuracy, the engagement surface faces toward the direction in which the engagement piece 14b tends to spread outward. By forming 14d, a predetermined portion of the engaging surface 14d is reliably engaged with the peripheral edge of the hole portion 11 in accordance with the thicknesses of both plate members during the engagement.

  As described above, the operator presses the joining end 6 of the side plate 2 against the joining end 7 of the back plate 3 with the joining clip 12 attached to the side plate 2 as shown in FIG. Therefore, the side plate 2 and the back plate 3 can be joined with one action, so that the joining work of the plate members constituting the cabinet 1 can be easily performed without performing a work such as screwing separately. The cabinet 1 can be manufactured at a low cost.

  Moreover, after inserting the engaging part 14 of the joining clip 12 into the hole 10 formed in the side plate 2, the head of the engaging part 14 is inserted into the hole 11 formed in the back plate 3, Since operations such as accurate alignment such as superposing the positions of both the holes 10 and 11 can be omitted, the side plate 2 and the back plate 3 can be easily joined.

  Further, here, the engaging portion 14 was pushed into the hole 11 of the back plate 3 in a state where the rear end face 15a of the joining clip 12 attached to the hole 10 of the side plate 2 was pressed toward the plate material T. For example, without pressing the rear end surface 15a of the bonding clip 12 attached to the hole 10 of the side plate 2 toward the plate material T, the bonding end 6 of the side plate 2 is pressed toward the back plate, and the hole of the back plate 3 is pressed. 11, the engagement surface 14 d is engaged with the peripheral edge of the hole 11 by pressing the rear end surface 15 a slightly protruding outward from the through hole 13 in a state where a part of the engagement portion 14 is inserted. You may do it.

  In the joining method described above, first, the joining clip 12 is attached to the hole 10 of the side plate 2 and then the side plate 2 and the back plate 3 are joined. There is a way of joining with 3. For example, as shown in FIG. 3A, the joining clip 12 is inserted from the through hole 13 of the side plate 2 in a state where the hole 10 of the side plate 2 and the hole 11 of the back plate 3 are superposed. And as shown in FIG.3 (b), even if the engaging part 14 of the joining clip 12 is inserted in both the hole parts 10 and 11 formed in the side board 2 and the back board 3, the engaging surface 14d is a hole. Engaged with the periphery of the portion 11, both plate materials T are joined. In this state where the holes 10 and 11 of the side plate 2 and the back plate 3 are overlapped with each other, the joining clip 12 formed separately from the side plate 2 and the back plate 3 is inserted and engaged with each other. The two plate materials T can be easily joined by the pressing operation.

  The side plates 2 and the back plate 3 are formed with the substantially U-shaped joining end portions 6 and 7, so that the side plate 2 and the back plate 3 made of a thin plate material can be used without using a reinforcing member or the like. In addition, the joint surfaces 6a and 7a having a larger area than the end surface of the plate T can be formed on the first bent piece K1 and the like at the bent joint end portions 6 and 7, Compared with the case where the end face of the other plate material T is brought into contact with one plate material T and the plate material T is joined in a L shape or a T shape in plan view, the joining strength can be effectively increased.

  Further, a substantially U-shaped joining end portion is formed by the plate material T, the first bent piece K1, and the second bent piece K2, thereby pressing one plate material T toward the other plate material T at the time of joining. At this time, since the outer surface of the second bent piece K2 parallel to the plate material T can be pressed, the strength is high and the flat surface portion can be pressed, so that the pressing can be easily performed. The plate material T is prevented from being bent or bent at the time of joining.

  Further, the first bent piece K1 and the second bent piece K2 are formed to be slightly longer than the front and rear length and width of the engaging portion 14 and the front and rear length and diameter of the holding portion 15, so that the joining clip is formed. Since the 12 engaging portions 14 and the holding portion 15 are concealed by the joining end portions 6 and 7, the appearance of the cabinet 1 is improved.

  Next, the board | plate material joining structure which concerns on Example 2 is demonstrated with reference to FIG.4 and FIG.5. In addition, the description which overlaps with the same structure as the said Example is abbreviate | omitted. FIG. 4A is a transverse plan view showing the joining clip, the side plate, and the back plate in the second embodiment, and FIG. 4B is a transverse plan view showing a state in which the joining clip is attached to the side plate. 4 (c) is a transverse plan view showing the side plate and the back plate after joining, and FIG. 5 (a) is a transverse plan view showing the joining clip, the side plate, and the back plate in the second embodiment. FIG. 5B is a cross-sectional plan view showing a state in which the joining clip is attached to the back plate, and FIG. 5C is a cross-sectional plan view showing the side plate and the back plate after joining. Hereinafter, the description will be made assuming that the lower side in FIG. 4 and FIG. 5 is the front side of the cabinet.

  FIG. 4A shows the side plate 18, the back plate 19, and the joining clip 20 before joining, and the side plate 18 and the back plate 19 are joined end portions 21 that are bent into a substantially U shape in plan view. , 22 are formed. The joining end portions 21 and 22 of the side plate 18 and the back plate 19 are obtained by bending the end portion of the plate material T, thereby bending the plate material T, the first bent piece K1 bent at a right angle from the plate material T, and the first bent piece. The second bent piece K2 is bent at a right angle from the end of the second plate K2 and is parallel to the plate material T so as to form a substantially U shape in plan view, and the plate material T and the back plate 19 of the side plate 18 are formed. In the first bent piece K1, that is, the joint surfaces 21a and 22a facing each other, holes 23 and 24 having the same diameter are formed, respectively.

  In addition, an attachment recess 25 is formed on the joint surface 21a of one side plate 18 so that the periphery where the hole 23 is formed is recessed. The depth (depth) of the mounting recess 25 is formed to be substantially the same as the length (thickness) of the holding portion 26 of the joining clip 20 described later.

  Next, the joining clip 20 in the present embodiment will be described in detail. As shown in FIG. 4 (a), the joining clip 20 is made of a material such as synthetic resin and is formed separately from the side plate 18 and the back plate 19, and the holes 23 and 22a formed on the joining surfaces 21a and 22a, respectively. A pair of front and rear engaging portions 28 that can be inserted into the pair 24 and a columnar holding portion 26 that is disposed at the center of the pair of front and rear engaging portions 28 and has an outer diameter larger than the inner diameter of the holes 23 and 24. And mainly consists of. The pair of front and rear engaging portions 28 are configured in the same manner, and are respectively provided with a cylindrical fitting portion 27 protruding from the front and rear surfaces of the holding portion 26 and from the front and rear end surfaces of the fitting portion 27. The center shaft portion 28a and a pair of engagement pieces 28b extending so as to gradually spread outward from the head of the center shaft portion 28a toward the central holding portion 26 side.

  The pair of engaging pieces 28b extending in a substantially umbrella shape from the distal end portion of the central shaft portion 28a are formed to be elastically deformable, and the end portion on the central side centering on the central shaft portion 28a side is the central shaft portion. It can be swung in a direction close to 28a. Further, an engaging claw 28c extends inwardly (from the center shaft portion 28a side) from the end of the engaging piece 28b, and the end faces on the center side of the engaging piece 28b and the engaging claw 28c will be described later. Thus, when the engaging part 28 is inserted into the hole parts 23 and 24, the engaging surface 28d engaged with the peripheral edges of the hole parts 23 and 24 is configured. Since the engagement surface 28d is a surface that faces in a direction substantially orthogonal to the longitudinal direction of the engagement piece 28b, the engagement surface 28d is inclined obliquely with respect to the plate material T when attached to the holes 23 and 24. It has become.

  Next, how to join the side plate 18 and the back plate 19 using the joining clip 20 in Example 2 will be described. First, as shown in FIG. 4A, one of the joining clips 20 (the right side in the figure). The engaging portion 28 and the fitting portion 27 are inserted into the hole portion 23 of the side plate 18. Then, when each of the pair of engaging pieces 28b passes through the hole portion 23, the pair of engaging pieces 28b are elastically deformed toward the central shaft portion 28a (see the two-dot chain line in FIG. 2B), and the end portions of the engaging pieces 28b are When coming out of the hole 23, the engagement piece 28b spreads outward by an elastic restoring force (see FIG. 4B).

  When the engagement piece 28b spreads outward, a part of the engagement surface 28d is engaged with the outer peripheral edge of the hole 23 as shown in the partial enlarged view (see) in FIG. In this engaged state, the engaging surface 28d is inclined with respect to the plate material T, and the end of the engaging piece 28b, that is, the end of the engaging claw 28c enters the hole 23. Become. Specifically, since the length dimension of the fitting portion 27 is formed to be slightly shorter than the thickness of the plate material T of the side plate 18 (back plate 19), the predetermined length formed in the hole portion 23 of the side plate 18. The tip of the engaging claw 28c enters the gap.

  Since the engaging surface 28d is engaged with the peripheral edge of the hole 23 in this way, the plate material T of the side plate 18 is sandwiched between the engaging surface 28d and the holding portion 26, so that the hole 23 of the side plate 18 The joining clip 20 is held and attached. In addition, both plate members T are strongly pressed toward the holding portion 26 by the elastic restoring force that the engagement piece 28b tries to spread outward, and the outer peripheral edge of the hole 23 is moved outwardly from the inside by the engagement surface 28d. Since the positional displacement in the direction of the joining surface 21a of the joining clip 20 with respect to the plate material T is regulated by this, the plate member T is attached without rattling.

  Further, at this time, the fitting portion 27 of the joining clip 20 is fitted into the hole 23 of the side plate 18, and the holding portion 26 of the joining clip 20 is fitted into the mounting recess 25 of the side plate 18. As described above, the fitting portion 27 is fitted into the hole portion 23 and the holding portion 26 is fitted into the mounting recess 25 of the side plate 18, whereby the positional deviation in the joining surface 21 a direction of the joining clip 20 with respect to the plate material T is displaced. Regulated reliably.

  Next, in a state in which the joining clip 20 is attached to the hole 23 of the side plate 18, the side plate 18 is brought close to the back plate 19, and the other engaging portion 28 (left side in the figure) of the joining clip 20 is connected to the hole 24 of the back plate 19. To insert. Then, as shown in FIG. 4C, the engagement portion 28 on the left side in the drawing is engaged with the hole 24 of the back plate 19 in the same manner as the engagement portion 28 on the opposite side (right side in the drawing). Note that the engagement state of the left engagement portion 28 with respect to the back plate 19 is the same as the engagement state of the right engagement portion 28 with respect to the side plate 18 in the drawing, and thus detailed description thereof is omitted. Thus, the side plate 18 and the back plate 19 are joined by engaging the engaging portion 28 on the left side in the figure with the hole 24 of the back plate 19.

  As shown in FIG. 4C, a pair of engaging portions 28 disposed on both sides of the central holding portion 26 in the joining clip 20 are respectively engaged with the hole portion 23 of the side plate 18 and the hole portion 24 of the back plate 19. In the combined engagement state, both plate members T are strongly pressed toward the holding portion 26 by the elastic restoring force that the engagement piece 28b is to spread outward, and the hole 23 is formed by the engagement surface 28d. , 24 are pressed from the inside to the outside, thereby restricting the displacement of the plate material T in the direction of the bonding surfaces 21a and 22a. Is prevented.

  In the second embodiment, one engaging portion 28 of the joining clip 20 is engaged with the hole 23 of the side plate 18, and the other engaging portion 28 is engaged with the hole 24 of the back plate 19. Although the example which joins both board | plate materials by making it match | combined was described, in the state which engaged the one engaging part 28 of the joining clip 20 with the hole 24 of the backplate 19, the other engaging part 28 was made into the side plate 18. You may make it join both board | plate materials by engaging with the hole part 23 of this.

  Moreover, in the present Example 2, although the mounting recessed part 25 which has the depth which the whole holding | maintenance part 26 of the joining clip 20 can fit in was formed in one board | plate material T (side board 18), for example in FIG. As shown, mounting recesses 25 ′ and 25 ″ having a depth capable of fitting half of the holding portion 26 are formed on the joint surfaces 21 a and 22 a of the plate material T of the side plate 18 and the plate material T of the back plate 19. Each may be recessed.
