Description

The present disclosure relates to fittings.

BACKGROUND ART Conventionally, it has been known that the surfaces of fittings such as doors are formed by fixing a surface material onto a base material using an adhesive (for example, see Patent Document 1).

JP2018-053636A

Fittings facing outdoors may be exposed to rain, snow, etc. In addition, water from various causes such as water from condensation or water used during cleaning may adhere to or flow onto the fittings, and a small amount of water may leak from the outer edge of the fittings to the surface material. It may get between the base material and the base material. In addition, condensation may occur inside the building material, and a small amount of moisture may enter between the surface material and the base material.

In some cases, fittings are equipped with hydrophobic parts that are sensitive to water, such as metal parts such as electronic locks and electronic equipment. If the surface material is fixed only with adhesive, there is a concern that water may enter the areas where the adhesive is not sufficiently applied between the surface material and the base material, come into contact with hydrophobic parts, and cause equipment malfunction. Ru.

The present disclosure includes a surface material disposed on the surface of the outdoor side, a base material disposed on the back side of the surface material, and a base material disposed penetrating a part of the base material and the surface material, and arranged on the outdoor side. The present invention relates to a fitting comprising an exposed hydrophobic component and an adhesive member provided to surround the hydrophobic component and arranged between the surface material and the base material.

It is a figure showing fittings of this embodiment. 2 is a sectional view taken along line AA in FIG. 1. FIG. 2 is a sectional view taken along line BB in FIG. 1. FIG. It is a schematic diagram showing arrangement of double-sided tape.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. An entrance door 1 as a fixture of this embodiment is installed at an entrance/exit opening of a building, and opens and closes the opening. The entrance door 1 has a frame 2 and a door body 3.

The frame body 2 has an upper frame 21 and a lower frame 22 that extend in the left-right direction when the entrance door 1 is viewed from the front, and a pair of vertical frames 23 that connect the upper frame 21 and the lower frame 22. The frame body 2 is configured by an upper frame 21, a lower frame 22, and a pair of vertical frames 23 framed in a rectangular shape.

The door body 3 is disposed inside the frame body 2 and is attached to be openable and closable. As shown in FIG. 1, the door body 3 includes a main door 31 and a child door 32. The main door 31 and the child door 32 each have a frame 33, a base material 34, and a surface material 35. The child door 32 further includes a hydrophobic component 4 and a double-sided tape 5 as an adhesive member. FIG. 2 is a sectional view of the child door 32. Referring to FIG. 2, the child door 32 will be explained. The main door 31 has generally the same configuration as the child door 32 except that the hydrophobic component 4 is not provided, so a description thereof will be omitted.

The frame 33 is a frame-shaped component arranged around the four peripheries of the door body 3, and is made of highly rigid metal or the like. The frame 33 is arranged generally along the outer edge of the door body 3. The frame 33 has an inner frame part 331 assembled into a frame shape on the center side in the thickness direction of the child door 32, and an outer frame part 332 fixed to the surface side of the inner frame part 331. The frame 33 is made of metal such as steel or aluminum.

The base material 34 is a flat member placed on the surface of the frame 33. The base material 34 constitutes the surface of the door body 3 and is, for example, a steel plate. A through hole 340 is formed in the base material 34 for arranging a hydrophobic component 4, which will be described later. The through hole 340 corresponds to the shape of the hydrophobic component 4, and is, for example, rectangular.

The surface material 35 is a decorative material that is placed on the outdoor side surface and the base material 34 is placed on the back side. The surface material 35 is a thin planar member having a pattern and material that form the design and texture of the surface of the door body 3. A through hole 350 is formed in the surface material 35 for arranging a hydrophobic component 4, which will be described later. The through hole 350 corresponds to the shape of the hydrophobic component 4, and is, for example, rectangular. The through hole 350 is overlapped with the through hole 340 of the base material 34.

The surface material 35 is adhered to the surface of the base material 34 with an adhesive 36. Adhesion is performed, for example, by applying a semi-solid highly viscous solvent to the surface of the base material 34 and overlaying the surface material 35 thereon. Since the adhesive 36 is very thin, it is difficult to apply it uniformly. Therefore, the thickness and application surface of the adhesive 36 are not necessarily constant, and as shown in FIGS. 2 and 3, a gap G may be formed between the surface material 35 and the base material 34. In FIGS. 2 and 3, the gap G is emphasized and schematically shown for explanation.

As shown in FIGS. 2 and 3, the hydrophobic component 4 penetrates through a portion of the base material 34 and the surface material 35, and is disposed in through holes 340 and 350 of the base material 34 and the surface material 35. Hydrophobic components are composed of electronic components and metal components that are vulnerable to water. The hydrophobic component 4 is an electronic lock, and a part thereof is exposed to the outside and a part thereof is arranged inside the door body 3. The hydrophobic components 4 are arranged on both the indoor side and the outdoor side of the door body 3 and are electrically connected to each other. The hydrophobic component 4 includes a non-contact key that can open and close by receiving radio waves, a sensor that detects the key, an electronic board that realizes these, and the like.

The double-sided tape 5 is provided so as to surround the hydrophobic component 4 and is placed between the surface material 35 and the base material 34. The double-sided tape 5 is a so-called double-sided tape, and is an adhesive member whose thickness and shape are formed within a certain range. The double-sided tape 5 is composed of an adhesive for adhesion and a base material for holding the adhesive and keeping the shape constant. As the adhesive, an acrylic adhesive having excellent heat resistance and weather resistance is preferable. Examples of the base material include paper, nonwoven fabric, rubber such as acrylic, and foamed material such as acrylic. Acrylic base materials have excellent water resistance and weather resistance. The foam base material has excellent vibration resistance and ability to follow surface irregularities due to its elasticity and thickness, making it suitable for outdoor use. An example of the double-sided tape 5 used in this embodiment is one in which the adhesive is an acrylic adhesive and the base is an acrylic foam material. Specifically, Y-4180 manufactured by 3M Japan Co., Ltd. and 241M manufactured by Kyodo Giken Kagaku Co., Ltd. can be exemplified.

As shown in FIG. 4, the double-sided tape 5 is placed horizontally around the hydrophobic component 4. That is, around the hydrophobic component 4, the horizontal portion 51 is arranged to extend in the horizontal direction, which is the left-right direction of the door body 3, and the horizontal portion 51 is perpendicular to the horizontal direction, and extends in the vertical direction, which is the vertical direction of the door body 3. When the vertical portion 52 is arranged as shown in FIG. It is arranged above the ends in the left and right direction of the horizontal portion 51 arranged on the lower side of the component 4. Thereby, when water leaks from the upper part of the door body 3 and is transmitted, it becomes possible to dam up the water by the horizontal portion 51.

A method of manufacturing the door body 3 will be explained. After the frame 33 is assembled into a frame shape and fixed, a base material 34 is placed on the surface of the frame. At this time, a through hole 340 for arranging the hydrophobic component 4 is formed in the base material 34. Next, one side of the double-sided tape 5 is pasted horizontally around the through hole 340. That is, the double-sided tape 5 is pasted along the upper and lower sides of the rectangular through-hole 340 so as to extend beyond the lateral ends of the through-hole 340 . Then, the double-sided tape 5 is pasted along the vertical side of the through hole 340 between the double-sided tapes 5 pasted in the horizontal direction. Next, an adhesive 36 for bonding the surface material 35 is applied to the surface of the base material 34. Next, the release paper of the double-sided tape 5 is peeled off, and the surface material 35 is pasted onto the base material 34 from above the double-sided tape 5 and the adhesive 36. Through holes 350 are formed in the surface material 35 at positions corresponding to the through holes 340 in the base material 34 . Therefore, the hydrophobic component 4 is fitted into the through holes 340 and 350 and fixed to the frame 33.

According to the fittings 1 of this embodiment, the following effects are achieved. The entrance door 1 is provided with a surface material 35 disposed on the outdoor surface, a base material 34 disposed on the back side of the surface material 35, and a part of the base material 34 and the surface material 35 penetrating through the surface material 35, It is configured to include a hydrophobic component 4 exposed to the outdoors, and an adhesive member 5 provided so as to surround the hydrophobic component 4 and arranged between a surface material 35 and a base material 34. Between the surface material 35 and the base material 34, the adhesive 36 may not be applied or there may be gaps in areas where there is less adhesive 36 due to omission of application of the adhesive 36 or difference in the thickness of the applied adhesive 36. G may be formed. Moisture, moisture, and fine dust that have entered from the outer edge of the door body 3 may enter this gap G. The portions of the hydrophobic component 4 that protrude outdoors from the through holes 340 and 350 may be covered with a waterproof member such as rubber packing. However, trace amounts of moisture change into liquid or gas under the influence of outside temperature, or move by penetrating dust. During this time, moisture and dust may get around the waterproof member and reach the hydrophobic component 4 inside the door body 3, causing corrosion, insulation, and failure. Furthermore, over time, waterproof members such as rubber packings around the hydrophobic component 4 may deteriorate and the waterproof effect may decrease.

According to this embodiment, the double-sided tape 5 is placed around the hydrophobic component 4 between the surface material 35 and the base material 34. Thereby, moisture that has entered the gap G caused by coating leakage or uneven coating can be prevented from coming into contact with the hydrophobic component 4. By arranging the double-sided tape 5 so as to surround the hydrophobic component 4, it is possible to prevent the adhesive 36 to be applied from spilling out and covering the hydrophobic component 4. Although the adhesive 36 takes time to dry, the double-sided tape 5 can be bonded immediately, so that quick handling can be achieved in the process of bonding the base material 34 and the surface material 35. Furthermore, by blocking moisture from circulating around the hydrophobic component 4 with the double-sided tape 5, deterioration of the water resistance and weather resistance of the adhesive 36 can be suppressed.

According to this embodiment, the adhesive member is formed to have a thickness within a certain range. By arranging the double-sided tape 5 which is an adhesive member having a constant thickness, the thickness of the adhesive 36 between the surface material 35 and the base material 34 can also be controlled. Further, it is possible to prevent leakage of application and uneven application of the adhesive 36.

According to this embodiment, the adhesive member is composed of double-sided tape 5. By using the double-sided tape 5, pasting is easy and workability is improved.

According to this embodiment, the double-sided tape 5 is disposed horizontally around the hydrophobic component 4. When moisture or dust containing moisture tries to enter around the hydrophobic component 4, it tends to move from above to below due to gravity. By arranging the double-sided tape 5 horizontally, it is possible to prevent moisture from moving up and down along the seam of the double-sided tape 5, and the waterproof effect is improved.

According to this embodiment, the hydrophobic component 4 is composed of an electronic component. This makes it possible to use non-contact electronic locks, to check and communicate with visitors using liquid crystal panels, and to support delivery companies, making it possible to support fittings with improved convenience and functionality.

According to this embodiment, the fittings are constituted by an entrance door. Thereby, the water resistance and weather resistance of the hydrophobic component 4 provided in the entrance door 1 can be improved.

The present disclosure is not limited to the above-described embodiments, and any modifications, improvements, etc. that can achieve the objectives of the present disclosure are included in the present disclosure. The function of the hydrophobic component 4 is not particularly limited. It may be a liquid crystal panel such as a touch panel, an intercom, etc., and may have any function.

The adhesive member 5 is not limited to double-sided tape. It may be in the form of a sheet or block, or it may be cut into the required shape and pasted on site. It is preferable that the shape has a certain adhesive strength.

The material of the surface material is not particularly limited. For example, metal plates (stainless steel, brass, copper, steel, etc.), tiles, wood, etc. can be used.

In this embodiment, the entrance door 1 is used as the fitting. However, the fittings are not particularly limited as long as they partition the openings so that they can be opened and closed. Fittings also include gates, etc.
