Description

The present invention relates to a panel in which a surface material is attached to a frame material.

Conventionally, a panel formed by attaching a surface material to a frame material by various mounting means (for example, glue, adhesive, bolt nut, locking piece, etc., or a mounting structure combining these) has been known. The design and strength of such a panel can be improved depending on the design and material of the surface material.

As such a panel, Patent Document 1 discloses a door-shaped panel to be attached to a housing body of a mailbox, and this panel is a stepped columnar connecting tool having small-diameter male screw portions at both ends. A surface material is attached to the frame material to form the frame material. Specifically, a state in which male screw portions at both ends of the connecting tool are inserted between the through hole of the frame material and the through hole of the surface material, and the frame material and the surface material are separated by a large-diameter intermediate portion of the connecting tool. Then, the surface material is attached to the frame material by screwing nuts to the male screw portions at both ends of the connector.

Japanese Unexamined Patent Publication No. 2008-264368 (Pages 3 and 4, Fig. 1)

However, in Patent Document 1, a mounting structure is such that a nut is screwed into a male screw portion of a connector inserted through a through hole of a surface material, and the surface material is sandwiched between an intermediate portion of the connector and a nut. Therefore, there is a possibility that the surface material may be deformed by screwing the nut into the connecting tool, and there is a problem that the selection of the surface material is restricted.

The present invention has been made by paying attention to such a problem, and an object of the present invention is to provide a panel having a high degree of freedom in selecting a surface material.

In order to solve the above problems, the panel of the present invention is used.

The handle base 50 of the frame member 5 has ribs 12b formed in a substantially lattice shape, an outer peripheral wall 12a formed integrally with the ribs 12b so as to surround the outside of the ribs 12b, and a front end portion of the outer peripheral wall 12a. A plate-shaped extension eave 50c extending outward in the surface direction of the lid portion 11 and a substantially square-shaped extension extending substantially vertically forward from the peripheral portion of the extension eaves 50c. The peripheral edge 50d and the substantially rectangular plate-shaped step portions 50e and 50e protruding forward from the surface 50a of the handle base 50 by the thickness of the surface material 6 at the upper and lower ends of the extension eaves 50c are provided. There is.

Further, the handle base 50 is formed with a fastener receiving portion 51 to which the fastener 16 is attached, and recesses 52, 53, 54, 55 recessed from the back surface 11b of the lid portion 11 to the front surface side.

As shown in the balloon of FIG. 5, the recess 55 is formed in a vertically long box shape in which the opening 55f opens on the back surface 11b side. Further, the lid portion 11 is provided with a bottom portion 55b at a position facing the opening 55f of the recess 55. At the upper part of the bottom portion 55b, a slit 55c (through hole) penetrating in the front-rear direction and elongated in the vertical direction, and at the lower end portion of the slit 55c, extending substantially vertically rearward from the back surface of the bottom portion 55b and along the slit 55c.

On the other hand, a round hole penetrating in the front-rear direction is formed in the lower portion of the bottom portion 55b.

Further, the surface 55a of the bottom portion 55b (see FIG. 4) has substantially the same planar shape as the outer peripheral wall 12a of the handle base portion 50, the rib 12b, and the front end surface of the extension eaves 50c, and these are collectively called the handle. The surface 50a of the base 50.

The recesses 52, 53 and the bottoms 52b, 53b have the same shape as the recess 55 and the wall 55b, and the recess 54 and the wall 54b have substantially the same shape as the recess 55 and the wall 55b. Therefore, the description is omitted. Further, in the following description, the recess 55 and the wall portion 55b will be described as an example, and the description of the other recesses 52, 53, 54 and the wall portions 52b, 53b, 54b will be omitted.

The surface material 6 is formed by punching and bending a stainless steel plate. Specifically, the substantially flat plate-shaped main surface portion 60 located on the front side of the surface material 6, the folded-back portions 61L and 61R formed by folding back the stainless steel plates at the left and right ends, and approximately 90 from the end portions of the folded-back portions 61L and 61R. The locking pieces 62, 63, 64, 65 are raised, and the locking pieces 62, 63, 64, 65 are slits 52c of the bottoms 52b, 53b, 54b, 55b of the frame member 5, respectively. , 53c, 54c, 55c are formed at positions corresponding to, 53c, 54c, 55c.

The plate thickness of the surface material 6 is the thickness of one stainless steel plate in the main surface portion 60, and the main surface portion 60 and the folded portion 61L or the folded portion 61R are formed in the portion where the folded portions 61L and 61R are formed. Since the portions 61R overlap each other, the thickness is equivalent to approximately two stainless steel plates. Furthermore, the left-right dimensions of the locking pieces 62, 63, 64, 65 are substantially the same as the plate thickness of the main surface portion 60, and the slits 52c, 53c, respectively of the bottom portions 52b, 53b, 54b, 55b of the frame member 5. It is the same size as or slightly shorter than the left and right dimensions of 54c and 55c.

As shown in the balloon of FIG. 5, the locking piece 65 is formed in a substantially upward inverted L shape when viewed from the right side, and the locking piece 65 is substantially vertically rearward from the end of the folded-back portion 61R. A base portion 65a extending to the base 65a and a head portion 65b having an arcuate portion 65d connected to the rear of the base portion 65a and protruding upward from the base portion 65a are provided, and a stepped shape is provided below the head portion 65b. The notch portion 65c of the above is formed.

An arc-shaped arc-shaped portion 65d that is convex upward is formed on the head portion 65b of the locking piece 65, and an inclined portion 65e that is continuous from the arc-shaped portion 65d to the base portion 65a and is inclined substantially linearly is formed on the front side. A straight line portion 65f substantially parallel to the main surface portion 60 connected to the arcuate portion 65d is formed on the rear side thereof.

Since the locking pieces 62, 63, and 64 have substantially the same shape as the locking pieces 65, description thereof will be omitted. Further, in the following description, the locking piece 65 will be described as an example, and the description of the other locking pieces 62, 63, 64 will be omitted.

Next, a mode in which the surface material 6 is attached to the frame material 5 will be described with reference to FIGS. 6 and 7 by taking the recess 55 and the wall portion 55b of the frame material 5 and the locking piece 65 of the surface material 6 as examples.

As shown in FIG. 6A, by aligning the locking piece 65 with respect to the slit 55c of the bottom 55b and moving it backward toward the slit 55c, as shown in FIG. 6B. The locking piece 65 can be inserted through the slit 55c. In the locking piece 65, the vertical dimension T2 of the locking piece 65 is shorter than the vertical dimension T1 of the slit 55c by the vertical dimension T5, but T1 = T2 may be used.

For convenience of explanation, in FIGS. 6A and 6B, the back surface 61R'of the folded-back portion 61R of the surface material 6 is arranged substantially parallel to the bottom portion 55b, and the slit 55c and the locking of the bottom portion 55b are locked. The embodiment in which the locking piece 65 is inserted into the slit 55c with the positions of the lower ends of the pieces 65 aligned is shown, but the present invention is not limited to this, and the back surface 61R'is engaged in a state of being tilted with respect to the bottom 55b. The stop piece 65 may be inserted through the slit 55c, or the locking piece 65 may be inserted through the slit 55c with the arcuate portion 65d of the locking piece 65 and the upper end portion of the slit 55c aligned. The mode of insertion of the stop piece 65 into the slit 55c is not limited.

From the state in which the locking piece 65 is inserted through the slit 55c of the bottom 55b shown in FIG. 6B, the surface material 6 is moved upward by the sum of the vertical dimensions T4 and T5 (see FIG. 6A) (see FIG. 6A). (Arrow in FIG. 7A), the upper end of the base portion 65a of the locking piece 65 comes into contact with the lower end of the locked portion 55g. Further, since the front-rear dimension W2 from the back surface 61R'to the end of the base portion 65a on the inclined portion 65e side is slightly longer than the front-rear dimension W1 of the bottom portion 55b, the head 65b of the locking piece 65 Is easy to engage with the back surface of the locked portion 55 g. In this state, the locked portion 55g is sandwiched between the head portion 65b and the back surface 61R'of the folded-back portion 61R of the surface material 6, which restricts the surface material 6 from moving in the front-rear direction. ing. In the following description, "contact locking" refers to a state in which the head 65b is located on the back surface of the locked portion 55g and the head 65b is reliably in contact with the back surface of the locked portion 55g. , And other states (for example, the state shown in FIG. 6B) will be described as “locking”.

At this time, since the locking piece 65 is guided along the long slit 55c, the locking piece 65 is restricted from tilting in the left-right direction, and the head 65b and the locked portion 55g are locked. Can be easily performed.

Further, since the inclined portion 65e of the head 65b is guided in a state of being in contact with the locked portion 55g, the surface material 6 is less likely to fall off when the surface material 6 is attached, and the head 65b is covered. It is possible to reliably and easily guide the locking position to the locking portion 55g.

Further, when the surface material 6 is attached to the frame material 5, the upper end portion of the inclined portion 65e is brought into contact with the locked portion 55g to guide the surface material 6, so that the back surface 61R'of the folded portion 61R of the surface material 6 is the handle base. Since it is located in front of the outer peripheral edge 50d of 50, it becomes difficult for the back surface 61R'of the folded-back portion 61R of the surface material 6 to come into contact with the outer peripheral edge 50d, and the locking piece 65 is locked to the locked portion 55g. be able to. As an additional note, if the locking piece 65 is inserted substantially perpendicularly to the slit 55c, the back surface 61R'of the folded-back portion 61R of the surface material 6 will come into contact with the outer peripheral edge 50d.

With the head portion 65b of the locking piece 65 locked to the locked portion 55g as shown in FIG. 7A, the screw 7 (fixed) from the opening 55f of the recess 55 to the female screw portion 55e of the cylindrical portion 55d. By screwing the member), as shown in FIG. 7B, the head 70 of the screw 7 comes into contact with the notched portion 65c of the locking piece 65 and is engaged. Therefore, the surface material 6 is restricted from moving in the vertical direction (the surface direction of the surface material 6) by sandwiching the locking piece 65 between the lower end of the locked portion 55 g and the head 70 of the screw 7. At the same time, the back surface 61R'of the folded-back portion 61R is brought into contact with the surface 55a of the bottom portion 55b, so that the movement of the surface material 6 in the rear direction (the direction in which the locking piece 65 is inserted into the slit 55c of the bottom portion 55b) is restricted. Since the head portion 65b of the locking piece 65 is locked to the locked portion 55g, the head portion 65b is in contact with the locked portion 55g even when a force for moving the surface material 6 forward is applied. By stopping, the movement of the surface material 6 in the front direction (the direction in which the locking piece 65 is pulled out with respect to the slit 55c of the bottom portion 55b) is restricted. The dimension from the female screw portion 55e of the cylindrical portion 55d to the upper end of the slit 55c of the wall portion 55b is substantially the same as or slightly the same as the vertical dimension T3 (see FIG. 6A) of the base portion 65a of the locking piece 65. It is formed short.

In this way, after inserting the locking piece 65 into the slit 55c of the wall portion 55b, the locking piece 65 is moved upward (in the surface direction of the surface material 6) along the slit 55c so that the locking piece 65 does not exist. Since the female screw portion 55e is formed, the space can be used efficiently.

In the same manner as described above, the surface material 6 can be attached to the frame material 5 by attaching the screws 7, 7, 7 to the other recesses 52, 53, 54 and the locking pieces 62, 63, 64. Therefore, the mounting structure is such that when the surface material 6 is attached to the frame material 5, a force that deforms the surface material 6 does not easily act on the surface material 6. As a result, the surface material 6 can be attached to the frame material without being deformed regardless of the strength of the surface material 6, so that the degree of freedom in selecting the surface material 6 is high.

Further, in the surface material 6, the locking pieces 62, 63, 64, 65 are formed by punching and bending a stainless steel plate. For example, the surface material 6 is locked to the main surface portion 60 of the surface material 6 by a method such as welding. Since the piece or the female screw portion is not attached or formed, it is difficult to deform or discolor the main surface portion 60 at the time of attachment or formation. From this, even if the surface material 6 is a thin stainless steel plate, the locking pieces 62, 63, 64, 65 can be formed without causing deformation or discoloration of the main surface portion 60.

The screw 7 supports the locking piece 65 from below by being screwed into the female screw portion 55e of the cylindrical portion 55d of the slit 55c of the bottom portion 55b. The front-rear dimension of the body portion 71 of the screw 7 screwed into the female screw portion 55e of the cylindrical portion 55d is longer than the plate thickness of the bottom portion 55b. As a result, as compared with the embodiment in which the screw is fixed above the locking piece 65, even if the weight of the surface material 6 acts on the frame material 5 via the locking piece 65 for a long period of time, the frame material 6 is used. 5 is hard to be deformed.

Since the front-rear dimension W3 from the front surface 55a of the bottom portion 55b to the back surface 11b of the lid portion 11 is longer than the front-rear dimension W4 of the cylindrical portion 55d to which the screw 7 is attached, the recess 55 is formed in the head 70. The head 65b of the engaging locking piece 65 can be stored, and fingers, clothes, and the like are prevented from being caught on the locking piece 65 from the back surface 11b side. Similarly, since the recess 55 can also store the head 70 of the screw 7, fingers, clothes, and the like are prevented from being caught in the head 70 of the screw 7.

Further, the front end of the body portion 71 of the screw 7 is in contact with or slightly separated from the back surface 60b of the main surface portion 60 of the surface material 6, and the screw 7 is not present on the surface 60a side of the main surface portion 60 of the surface material 6. Therefore, for example, by screwing a nut into the body of a screw protruding from a through hole in the main surface portion toward the surface side of the main surface portion, the surface material is not deformed as in the case where the surface material is attached to the frame material.

When the surface material 6 is attached to the frame material 5, the main surface portion 60 of the surface material 6 covers the surface 50a of the handle base portion 50, and the plate-shaped step portions 50e and 50e are arranged between the folded portions 61L and 61R. The peripheral edge of the main surface 60 is surrounded by the outer peripheral edge 50d of the handle base 50 of the frame member 5, and the gap in the peripheral edge of the surface material 6 is the folded-back portions 61L, 61R of the surface material 6 and the plate-shaped step portion 50e, It is blocked by 50e. Therefore, it becomes difficult to access the back surface 60b of the main surface portion 60 through the gap, and the locked state by the locking piece 65 can be reliably maintained. Further, the surface material 6 is surrounded by the outer peripheral edge 50d of the handle base portion 50, and the surface 60a of the main surface portion 60 of the surface material 6 and the front end surface of the outer peripheral edge 50d form substantially the same surface, so that the aesthetic appearance is good. ..
[Modification 1]

Further, in the above embodiment, the configuration in which the recess 55 includes the opening 55f has been described, but the modified example 1 including the recess having no opening will be described with reference to FIG.

As shown in FIG. 8, the recess 155 is a substantially rectangular space formed at a substantially central portion in the thickness direction of the frame member 105. A slit 155c is formed in the bottom portion 155b, and a female screw portion 155e is formed on the back side of the frame member 105. By screwing the screw 107 into the female screw portion 155e, the body portion 171 of the screw 107 comes into contact with the lower end of the locking piece 65, and the locking piece 65 is sandwiched in the vertical direction by the body portion 171 and the locked portion 155 g. At the same time, the downward movement of the locking piece 65 is restricted.
[Modification 2]

Further, in the above embodiment, the locking piece 65 has been described as being formed at the end of the folded-back portions 61L and 61R, but a modified example in which the locking piece is formed in addition to the end of each folded-back portion. 2 will be described with reference to FIG.

As shown in FIG. 9, the surface material 206 includes folded portions 261L and 261R in which a stainless steel plate is folded back at the left and right ends and each end abuts at substantially the center in the left-right direction of the surface material 206, and folded portions 261L. Locking pieces 262,263,264,265, which are cut and raised by approximately 90 degrees at the left end and the right end of the folded-back portion 261R, are provided. In this embodiment, when the surface material 206 is attached to the frame material 5, the gap formed between the main surface portion 260 of the surface material 206 and the surface 50a of the handle base portion 50 of the frame material 5 can be reduced. Therefore, the surface material 206 has a structure that is not easily deformed.

Further, in the surface material 206, since the portions where the folded portions 261L and 261R are formed have a plate thickness equivalent to that of about two stainless steel plates, the strength of the entire surface material 206 is compared with that of the surface material 6. It is improving. On the other hand, the surface material 6 is lighter in weight than the surface material 206, and the locking pieces 62, 63, 64, 65 can be easily formed.
