Description

  The present invention relates to an aluminum wall table, and more particularly to a wall-mounted aluminum table used for mounting an object such as an air conditioner on a wall surface.

Conventionally, iron wall mounts have been used to install outdoor units such as air conditioners on outdoor wall surfaces (for example, Patent Documents 1 to 3).
However, iron is easily rusted and has a problem that workability is poor due to its heavy weight.
Therefore, an aluminum wall mount that is light in weight, has good workability, is resistant to rusting, and has a rich aesthetic appearance on the processed surface has been proposed.

  For example, as shown in FIG. 10, such an aluminum wall surface table is fixed in a horizontal direction along the wall surface and is connected to the horizontal frame 41 having a substantially constant width and the horizontal frame 41. A pair of vertical frames 42 arranged in a vertical direction along the vertical direction and connected to the vertical frames 42, extending from the wall surface toward the front, and for placing the air conditioner thereon And a pair of arms 43. The arm 43 has a U-shaped cross-sectional shape with an open lower end, is long in the vertical direction of the end connecting the vertical frame 42 on the wall surface side, and has a shape in which the length becomes shorter toward the front. It is processed and can secure the strength for supporting the air conditioner and can be firmly connected to the vertical frame 42.

Usually, the aluminum horizontal frame 41, the vertical frame 42, and the arm 43 are formed by extrusion. Therefore, when processing a member whose thickness (width or height) is not constant, such as the arm 43, once a hollow member having a constant thickness is formed by extrusion molding, It is formed by dividing into two in the direction (not shown).
However, when the shape of the arm 43 is a shape obtained by dividing the aluminum hollow member in this way, the edge 43a of the divided portion is exposed at the lower end thereof, and during the construction of assembling the wall surface table, There is a risk of hurting hands and arms when passing by the side after mounting.

In addition, a line-shaped pattern 43b for the design process is usually attached to the extruded product made of aluminum by providing a minimal protrusion on the mold during extrusion processing. When an extruded product is divided in an oblique direction, the line-shaped pattern 43b and the dividing line intersect with each other at an acute angle. The danger during work increases.
Furthermore, since the edge 43a of such an arm 43 is not normally processed at all, the aesthetics of the wall surface table itself are impaired.
JP 2001-182970 A Japanese Patent Laid-Open No. 11-182898 Japanese Patent Laid-Open No. 8-136011

An embodiment of an aluminum wall surface mount of the present invention will be described in detail with reference to the drawings.
Example 1
The aluminum wall surface table 10 of this embodiment is mainly fixed to the wall surface as shown in the perspective view of FIG. 1 and the top, front, and side views of FIGS. 2 (a) to 2 (c). A horizontal frame 11, a pair of vertical frames 12 connected to the horizontal frame 11 and disposed along the wall surface, and connected to the vertical frame 12, extending from the wall surface side toward the front surface, and supporting an air conditioner and the like. And a pair of arms 13.

As shown in FIG. 2D, which is a cross-sectional view taken along line AA in FIGS. 2C and 2C, the arm 13 has a substantially constant cross-sectional shape from the wall surface side to the front surface, for example, rectangular. The wall body 14 constituting the hollow shape (the support piece 14d is located at the end thereof) and the reinforcing wall 15 formed on the inner side of the wall body 14 so as to extend over both side surfaces of the wall body 14 are configured. Has been.
By forming the wall body 14 constituting such a hollow shape, the amount of aluminum used can be further reduced in addition to the lightness of the aluminum itself while ensuring the strength of the arm, and the weight can be further reduced. As a result, work efficiency can be improved. Moreover, the strength of the arm itself can be further increased by forming the reinforcing wall 15 inside the wall body 14 constituting the hollow shape.

The outer periphery of the wall body 14 constituting the hollow shape is usually about 160 to 280 mm, and the total length of the arm 13 is about 350 to 550 mm.
A groove 14b extending from the wall surface side to the front surface is formed on the upper surface 14a of the wall body 14, and the width of the groove 14b is usually a fastening member 37 for supporting the air conditioner, for example, a bolt body. It is set to be slightly wider than the width and narrower than the width of the bolt head or nut. As shown in FIG. 1, a vibration isolating rubber 38 for absorbing vibration of the air conditioner is attached to the fastening member 37.

A pair of support pieces 14 d is formed at the end of the arm 13 on the vertical frame 12 side. The support piece 14d has a wall body upper surface 14a constituting a hollow shape of the arm 13, a reinforcing wall 15 and a wall body lower surface 14c so as to support the vertical frame 12 in the vertical direction with respect to the arm 13. And it is comprised as an extended side surface of the wall 14 which comprises a hollow shape. The depth of the support piece 14d (the lengths of the cutout portions of the wall upper surface 14a, the reinforcing wall 15 and the wall lower surface 14c) is set to a length substantially corresponding to the depth of the vertical frame 12, and the maximum portion In, for example, it is about 35-55 mm.
Such a support piece 14d can be provided with a strength sufficient to withstand bending stress.

The support piece 14d in the arm 13 is formed with two fastening members 18, for example, holes 19 into which bolts are inserted, arranged side by side in the vertical direction.
Further, as shown in FIG. 2D, the vicinity of the outer periphery of the hole 19 into which the bolt is inserted is formed to be equal to or thicker than other portions of the wall body 14. That is, in the vicinity of the end on the vertical frame 12 side, the thickness above the reinforcing wall 15 of the arm 13 and the thickness below the wall body 14 constituting the hollow shape are the reinforcing wall 15 and the wall upper surface 14a. It is set to be equal to or thicker than the thickness.
Specifically, the thickness t1 of the upper wall body of the reinforcing wall 15 indicated by 14e is thicker than the thickness t2 of the wall body 14 immediately below the reinforcing wall 15, and is below the wall body 14 constituting the hollow shape. The thickness is set to be thicker than the thickness t2. The thickness t1 of the wall body 14e is set to be slightly thicker than the thickness of the lower side of the wall body 14 constituting the hollow shape. For example, the thickness t1 is about 1.5 to 4.0 mm, the thickness t2 is about 0.7 to 2.0 mm, and the thickness below the wall body 14 constituting the hollow shape is 1.2 to 3.5 mm. More specifically, t1 = 2.2 mm, t2 = 1.0 mm, and the thickness of the lower side of the wall body 14 constituting the hollow shape = 2.0 mm.

The horizontal frame 11 is configured by integrally forming a facing portion 11a disposed substantially parallel to the wall surface and a projecting portion 11b disposed below the facing portion 11a and projecting toward the front surface.
The vertical frame 12 has a substantially A-shaped cross section (see FIG. 3C described in detail later), and when the vertical frame 12 is inserted between the support pieces 14d, the holes of the arm 13 are formed. A hole is provided in the side surface corresponding to the position 19. Further, in the vicinity of the upper end portion of the vertical frame 12, a notch portion 21 (see FIG. 2C) for engaging with the protruding portion 11b of the horizontal frame 11 is provided.

The horizontal frame 11, the vertical frame 12, and the arm 13 that constitute the wall surface table in the present invention are manufactured by extrusion molding of aluminum. That is, by putting a block of aluminum into an extrusion molding machine and softening the aluminum, it is extruded through a die having a shape corresponding to the cross-sectional shape of the horizontal frame 11, the vertical frame 12, and the arm 13, and cut into a predetermined length. Can be manufactured.
In particular, in the arm 13 described above, first, the groove 14b of the wall upper surface 14a, the reinforcing wall 15, and the wall lower surface 14c are integrally extruded.
Next, the obtained molded product is cut into a predetermined length.
Thereafter, at one end of the arm 13, the wall upper surface 14a, the reinforcing wall 15 and the wall lower surface 14c are cut out in an arc shape so as to protrude inward from the end. Thereby, the support piece 14d is formed on the one end side.
By such extrusion molding, the horizontal frame 11, the vertical frame 12 and the arm 13 having a complicated cross-sectional shape can be accurately and easily molded without going through complicated operations.

In the wall surface table of the present invention, the connection between the horizontal frame 11 and the vertical frame 12 is performed by engaging the notch portion of the vertical frame 12 with the protruding portion 11b of the horizontal frame 11 and penetrating from the front side to the wall side, For example, it is performed by fixing using bolts and nuts.
Further, the arm 13 and the vertical frame 12 are arranged between the pair of support pieces 14d in the arm 13 as shown in the side view, the top view, and the rear view of FIGS. 12 is inserted, and the bolt as the fastening member 18 is inserted into the hole 19 and the hole provided in the vertical frame 12, and fixed using a nut.

In order to adjust the angle of the arm 13 in the horizontal direction, an adjuster is attached to the arm 13 in the vicinity of the connection portion between the arm 13 and the vertical frame 12.
This adjuster has a screw 23 that can project the head 22 from the end of the arm 13 on the side of the vertical frame 12 so as to abut against the wall surface, and this screw 23 is screwed together so that the head 22 is connected to the end of the side of the vertical frame 12. The screw hole 24 can be moved forward and backward. The screw hole 24 is formed at the bottom of the wall body 14 constituting the hollow shape of the arm 13, that is, above the wall lower surface 14c.

As described above, when the arm 13 is processed by extrusion molding, the screw hole 24 is formed by extruding the shape of the mouthpiece of the extrusion molding machine as a shape corresponding to the original hole of the screw hole 24. A base hole extending from the wall surface side to the front surface is formed, and then the thread is cut by the amount of insertion of the adjuster screw 23.
When packing or transporting the wall surface table, for example, as shown in FIG. 1, the arm 13 is moved vertically by removing the upper fastening member 18 at the fastening portion between the arm 13 and the vertical frame 12. It can extend in the same direction as the frame 12 and facilitate packing and transportation.

Example 2
The wall surface table of this embodiment is a part of the horizontal frame, the vertical frame, the arm and / or the fastening member so that the horizontal frame, the vertical frame and / or the arm are not in direct contact with the fastening member for fastening them. An example is shown in which the entire surface is covered with an insulating or anticorrosive material.
For example, as shown in FIG. 4, a round head root bolt 26 and a disc spring nut 27 are used as fastening members, and the surface of these round head corner bolt 26 and disc spring nut 27 is, for example, 10 μm made of acrylic resin. Example 1 is substantially the same as Example 1 except that a film 28 is formed by electrodeposition with a film thickness of a certain degree.

Usually, bolts and nuts are formed in the holes 19 and the vertical frame 12 at the fastening portion between the horizontal frame 11 and the vertical frame 12, particularly at the fastening portion between the vertical frame 12 and the arm 13, as shown in FIG. It will be in contact with the inner wall of the hole provided.
Further, the fastening member is usually formed of iron and protected by a rust preventive agent mainly composed of zinc or aluminum powder. However, the rust preventive agent is eluted by rain and moisture in an outdoor environment in 10 to 20 years, and there is a possibility that iron which is a base of the fastening member comes into contact with aluminum. Then, due to the difference in natural potential, corrosion may be induced on aluminum by physicochemical action.

  Thus, as described above, by applying a film to the fastening member, direct contact between iron and aluminum can be prevented, potential difference can be prevented from being balanced, and aluminum corrosion can be prevented. In particular, when the film is formed by electrodeposition coating, a thin film-like film can be formed uniformly, and coating defects do not occur over details such as the inside of the hole of the fastening member and gaps such as screw grooves. This is advantageous because the entire surface can be satisfactorily covered.

The acrylic resin coating 28 can be formed by appropriately selecting known materials and conditions by an electrodeposition coating apparatus capable of realizing the process shown in FIG.
First, a fastening member is mounted on a hanging machine, pre-degreasing and degreasing cleaning (S1) are performed, and then water washing is performed twice (S2). Next, the surface of the fastening member is adjusted (S3), and film formation is performed (S4).
Thereafter, washing with water twice and washing with pure water once (S5), cutting off, and performing electrodeposition while passing an electric current in the solution (S6). Subsequently, the obtained fastening member is washed twice with water and once with pure water (S7), and is introduced into a baking drying oven and dried (S8).
The obtained fastening member is unloaded from the hanging machine and the quality of the coating is confirmed.

Example 3
As shown in FIG. 6, the wall surface table of this embodiment is configured by a wall body in which the arm 13 forms a slightly thin hollow shape, and in addition, an L-shape is formed at the connecting portion between the arm 13 and the vertical frame 12. The reinforcing plate 25 is substantially the same as the first embodiment except that the reinforcing plate 25 is attached.
Such a reinforcing plate 25 is made of, for example, an aluminum plate having a thickness of about 2 to 5 mm, and has vertical and horizontal lengths of about 75 to 90 mm. The reinforcing plate 25 is fixed to the arm 13 by rivets 25a.

  With such a reinforcing plate 25, even when the arm 13 is formed with a minimum thickness, it is possible to improve the strength against bending stress that is the largest when an air conditioner or the like is placed.

Modification (1) The coating on the fastening member in Example 3 can be made of any insulating or anticorrosive material regardless of the acrylic resin. Moreover, such a film is preferably hard and can be formed into a thin film (for example, a film thickness of about 7 to 30 μm).
Such a film can be formed by various methods such as electrodeposition, spraying, dipping, and coating. In particular, when it is formed by electrodeposition coating, it is advantageous because a film can be reliably formed over details such as the inner surface of the hole and gaps such as screw grooves.
Note that the insulating or anticorrosive coating may not be formed on the entire surface of the fastening member, but may be formed only on a part of the surface in contact with the aluminum.

Moreover, after forming the horizontal frame 11, the vertical frame 12, and the arm 13 (including holes and edge portions), the insulating or anticorrosive film may be formed on a part or all of the surfaces. In this case, the film may be formed by anodizing or alumite in addition to the above materials and film forming method.
The insulating or anticorrosive coating of the fastening member, the horizontal frame 11, the vertical frame 12, and the arm 13 may be formed with only one layer, or may be formed with a laminated structure. In particular, when forming on the horizontal frame 11, the vertical frame 12, and the arm 13, it is preferable to form a two-layer structure in which a film by anodization is formed and then an electrodeposition coating film is formed thereon. In the case of forming coatings having different types of laminated structures as described above, it is advantageous that the coating itself does not peel off even when a large load is applied, and these members can be firmly coated.
Further, in a form in which the surface of a part or all of the fastening member, the horizontal frame, the vertical frame and / or the arm is covered with an insulating or anticorrosive material, the insulating or anticorrosive material is used as the fastening member, the horizontal frame, the vertical frame. And / or not only in close contact with the arm, but also in a state of being interposed between these members, that is, in a state in which some of these members are covered with an insulating or anticorrosive material. Also good. For example, as shown in FIG. 7, there is a configuration in which a bush 31 made of an insulating or anticorrosive material is interposed in a portion where the body of the bolt 30, the head 32 and the nut 33 are in contact with the vertical frame 12 or the like. Can be mentioned.

The bush 31 has a body portion that is 1/2 or shorter than the length of the fastening member and has a slightly larger diameter than the body of the fastening member, and at its end so as not to fall into the hole. It has a head larger than the hole. Further, a protrusion 31a is formed in the middle of the body part or slightly outside the head part.
The bush 31 is first inserted into the hole from the left and right. At this time, the protrusion 31a plays the role of a click. Next, the bolt 30 is inserted into the bush 31 and the nut 33 is tightened.
The protrusion 31a can prevent the bush 31 itself from coming out of the hole, and the bush 31 can be self-supporting in the hole. In addition, by tightening the nut, the left and right bushes collide with each other to perform the spacer function.

Examples of the material for the insulating or anticorrosive coating include polyester, urethane, and epoxy resin-based paint.
Moreover, you may use combining the film by an insulating or anticorrosive material, and the intervention of an insulating or anticorrosive material like a bush.

(2) The fastening member may be a rivet, a caulking or the like in addition to the bolt and nut.
(3) As shown in FIG. 1, caps or covers 35, 34, and 36 that cover edges (cut surfaces, end surfaces, etc.) may be provided at the ends of the horizontal frame, the vertical frame, and the arm.
(4) The head 22 constituting the adjuster may be formed with a diameter smaller than the width of the vertical frame 12, but may be formed with the same or larger diameter. Furthermore, the head 22 may be formed with a diameter that protrudes from the lower end of the vertical frame 12. As described above, when the head 22 protrudes from the side surface or the lower end of the vertical frame 12, the angle of the arm 13 can be easily adjusted from the front side of the wall surface table.
Further, the screw hole 24 constituting the asher may be arranged on either the upper side or the lower side as long as it is adjacent to the wall body constituting the hollow shape constituting the arm 13.

(5) As shown in FIGS. 8A and 8B, the support piece 14d may be inserted inside the vertical frame 12 at the end of the arm 13 to support the vertical frame 12. In this case, a notch 134 corresponding to the height of the support piece 14 d of the arm 13 may be formed on the front surface side of the lower end of the vertical frame 12. Also, as shown in FIGS. 9A and 9B, the corner 13 at the lower end of the vertical frame 12 has a width corresponding to the thickness of the support piece 14d so that the support piece 14d of the arm 13 can be inserted. A pair of left and right slits 135 and 136 may be formed respectively.
(6) On the side surface of the arm 13, a hole that can penetrate the drain pipe as indicated by 43c in FIG. 10 may be formed. With such a hole, the drain pipe that hangs down from a relatively high part of the wall surface can be held to the side, and damage to the drain pipe due to a large shake caused by wind and rain can be minimized.

  The wall surface table of the present invention can be used in a wide range of fields not only for placing an air conditioner, but also for all devices that can be placed on a wall surface, an indoor inner wall surface, particularly an outdoor outer wall surface. it can.
