JP5675202B2 - Mold material and frame structure using the same - Google Patents

Description

  The present invention relates to a mold material made of, for example, an aluminum material, and a frame structure using the same, and in particular, improves versatility, facilitates assembly work, ensures the naturalness of the finished shape, and provides sufficient strength. It relates to new shapes and structures that meet complex requirements such as securing.

  For example, for display signboards made of aluminum, and for molds for joinery and building materials, as shown in FIG. 7, a base pillar 101 is provided at the center of the mold 100, and an outer constricted ant is formed around it. The space 102 is configured, and members for function expansion are attached using this portion. For example, when assembling other members to the ant-shaped space 102, a special nut 103 that enters the bayonet shape is applied to the ant-shaped space 102, and the bolt 104 is screwed into the special nut 103 to attach the functional member. It is carried out.

The special nut 103 as described above must be used in assembling the molds having such shapes or attaching other functional members, and the versatility cannot be sufficiently obtained.
In addition, the release portion of the ant-like space 102 is relatively wide, and this portion is visually observed, so that a sufficiently finished appearance cannot be obtained. In addition, when trying to fix these mold materials with tapping screws, only the screw pockets 104 continuous in the cross-sectional direction are provided, and this alone limits the selection range of the fixing structure.
Of course, as shown in FIG. 7, as a method of connecting the mold members 100 to each other, a member using a connecting member 105 having a fitting shape corresponding to the cross-sectional shape of the mold member 100 has been proposed in consideration of the design. Even if it is a method, you have to prepare the separate connection member 105 according to a connection form for every size.
Incidentally, as shown in the following patent document, there have been proposed devices in which the assembly structure of the mold material is devised, but none of them has solved the problems of the conventional methods.

  The mode for carrying out the present invention includes an embodiment described below, and includes various improved embodiments based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
First, what is indicated by reference numeral 1 is a mold material according to the present invention, and reference numeral 2 indicates a frame structure using this mold material 1.
First, the mold material 1 will be specifically described. As shown in FIG. 1, FIG. 2, and FIG. 4, the mold 1 is a square columnar member that is integrally formed by combining peripheral plates 11 having a uniform width so as to have a square shape on a four-sided cross section. is there. In addition, when the inside is left hollow, it should be expressed as a rectangular tube shape strictly. However, when configured as the frame structure 2, it is natural that the formwork 1 is recognized as a column, In this specification, it is expressed as a quadrangular prism. The outer surface portion 12 of each peripheral plate 11 has a planar shape that serves as a reference plane. A screw pocket 13 is provided at the center of the peripheral plate 11 in the width direction. The screw pocket 13 is formed by forming a screw pocket forming portion 14 formed by cutting out the material of the peripheral plate 11 substantially into a U-shaped section from the peripheral plate 11. Formed as.
As can be understood from such a shape, it is most suitable that the mold material 1 is configured as a drawing material using an aluminum material. However, a resin material may be used as long as the strength can be guaranteed. The inside of the mold 1 may be left hollow, but if necessary in terms of strength, for example, foamed urethane or the like can be injected to further increase the strength.

When the screw pocket 13 of the present invention is viewed in detail, as shown in FIG. 2, the screw pockets 15 are opposed to the open side close to the outer edge portion and the back portion 16 side, respectively, instead of being simply a recessed groove shape. As an example, a total of 4 lines are formed. The back portion 16 is an arc-shaped closed space having the same diameter as that of the open side, and three recessed portions 17 are formed therein as an example. The inner portion 16 can be a screw pocket when a screw is received in the cross-sectional direction.
In addition, although this mold material 1 illustrated the thing of the cross-sectional square in FIG.1, FIG.2, FIG.4, although illustration is abbreviate | omitted, a cross-sectional rectangular thing may be used.
Further, each peripheral plate 11 is provided with a screw pocket 13, but it is also possible to provide this on at least one peripheral plate 11 or two opposing peripheral plates 12.

A frame structure 2 using the mold material 1 can be configured using such a mold material 1.
First, before describing each assembly structure in the framework structure 2, its application examples will be mainly described.
The structure shown in FIGS. 1 and 3 is a structure that can be installed as a signboard or the like, and this type of frame structure will be described with reference numeral 2A.
Specifically, the frame structure 2A has a form in which four pieces of the mold material 1 are combined and the lower part is extended into a pillar shape. In the connection, the panel 23 is fixed by screws 22 while interposing the connection piece 21 and has a signboard function.
In addition, the frame structure 2B shown in FIG. 5A is provided with a caster 25 by providing a leg portion and a caster 25 in order to make it easier to move and install the signboard-like frame structure. is there.
Similarly, the frame structure 2C shown in FIG. 5 (b) is like a fence in which the width is further extended in the lateral direction.

  Further, the frame structure 2D shown in FIG. 5 (c) can be applied as, for example, an indoor partition. The frame structure 2D is configured by combining four mold materials 1 into a square surface shape, and at least one of the upper and lower sides of the columnar mold material 1. A jack piece 26 is applied to the end of the floor so as to stretch between the floor surface and the ceiling surface.

Furthermore, the frame structure 2E shown in FIG. 6A is used as a stool-like seat or stepping board, and the mold material 1 arranged in the form of four leg pillars is divided into four rectangular shapes on the upper side and the lower side. It is combined by the mold material 1 configured in a shape. Furthermore, the frame structure 2F shown in FIG. 6B is configured in a bench shape, and in this case, the parts constituting the seat plate portion are enlarged as shown in FIG. 6B, for example. In addition, instead of connecting them by connecting the mold members 1 together, a method of joining them by overlapping them is used.
Specifically, the connection piece 214 having a gate shape is used for bonding.

Hereinafter, the joining mode of these assembly structures will be described.
When the mold material 1 is attached at right angles as the most general form, the cut surface of the mold material 1 itself is, for example, a so-called oat structure, in which the joining side end of each mold material 1 is cut and formed at 45 ° and butted. There may be a butt-butting structure with a 90 ° open edge (see FIGS. 1 and 3).
In this case, an L-bending connection piece 211 obtained by bending a band plate-like member by 90 °, or a planar L-shaped connection piece 212 or a T-shaped connection obtained by punching the plate-like member into an L shape. The piece 213 is placed on the side surface to connect the two. Of course, other than the connection piece 21 described above, it is needless to say that a flat plate-shaped connection piece 21 having a shape corresponding to the attached aspect, or a connection piece bent at an appropriate angle is used although illustration is omitted.
Specifically, a screw hole 221 is formed in each, and the screw 22 is screwed toward the screw pocket 13 in the mold material 1 using this part.
As shown in an enlarged view in FIG. 2, the screw is engaged with the screw thread due to the presence of the screw hooking rib 15, so that the screw is reliably screwed.
In addition, as shown in FIG. 1, the screw pocket 13 exists also inside the mold material 1 in the part where the panel 23 is accommodated in the sign-like frame structure 2A, and the panel 23 is fitted in this part. By this, it can fix reliably, without using another special fixing means.

In addition, in the Example shown in FIG.1, FIG.5 (b) and FIG. 6, as shown in FIG. 6, in order to protect this site | part, the leg part edge part of signboard-shaped frame structure 2 is cut off. Alternatively, the grommet 24 may be used to close this portion. The grommet 24 is a rectangular piece that closes the open portion at the end of the mold 1, and, for example, a resin molded into an L shape as shown in FIG. 6 to ensure the safety of the corner. You may use the grommet made from.
In this case, the engagement between the grommet 24 and the mold material 1 may be such that an engagement portion 241 that fits into the screw pocket 13 in the mold material 1 is formed with respect to the grommet 24. Further, as shown in FIG. 6, the grommet 24 that protects only the end face may be provided with a protrusion that engages with the screw pocket 13 of the mold material 1, or a protrusion 242 that fits into the inner peripheral surface of the mold material 1. It may be provided.

  Each type of frame structure 2 can be configured by such a basic assembly structure, but the frame structures 2B and 2C having casters 25 and the partition-like frame structure 2D having jack pieces 26. In that case, the mounting structure according to it is taken. That is, when the caster 25 or the jack piece 26 is attached, an appropriate screw hole 221 is formed in the caster mounting plate 251 as shown in FIG. Take the form of attaching to the surface. Further, in the case of the partition-like frame structure 2D, when the jack piece 26 is provided on the end surface of the mold 1, a screw hole 221 is formed in the base plate 261 of the jack piece 26 as shown in FIG. Use this to fix the screw. The position where the screw is screwed is preferably the innermost part of the screw pocket 13 of the mold 1 as shown in an enlarged view in FIG. In this case, due to the presence of the recessed portion 17, the top of the screw thread of the screw 22 is appropriately engaged with the wall surface portion that is formed in a relatively convex shape adjacent to the recessed portion 17, so that the screwing is reliably performed. And the screw 22 has less twisting resistance, and is preferable for improving the straight running stability of the screw 22.
