Description

The present invention relates to a hinge for a swing door that allows wiring to pass through.

In recent years, electric locks have become increasingly common on swing doors. In such cases, when wiring the electric lock's connection wires to the structure's power source, it is necessary to use conductive fittings (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 11-26116

However, when using electrically conductive fittings, which are specialized products other than hinges, on swing doors, the cost of installing the swing door increases, and depending on the type of electrically conductive fitting, the door's appearance can be compromised.

The present invention was made to solve the above problems, and aims to provide a hinge for swing doors that reduces the number of parts and contributes to improving design.

To achieve the above objective, the hinge for a swing door of the present invention (hereinafter sometimes referred to as the "hinged door hinge") comprises a hinged door embedded portion and a support mounting portion, the hinged door embedded portion being pivotally supported by the support mounting portion, and the support mounting portion is characterized in that a wiring space portion (first wiring space portion) communicating with the hinged door embedded portion is formed.

Furthermore, this hinge for a swing door may also include an interior portion inserted into the swing door embedded portion, and the interior portion, together with the swing door embedded portion, is pivotally supported on the support mounting portion so as to be freely rotatable, and the interior portion may have a second wiring space formed therein that communicates with the wiring space of the support mounting portion.

Here, the support mounting portion is a portion that is mounted to the support. The support is a structure to which the hinged door is attached, and it does not matter what type it is, such as a sleeve wall or mounting panel.
In addition, taking design into consideration, the permanent door hinge is designed to be embedded in the door, with an embedded part in the door. However, the door to which the permanent door hinge can be attached can be any type, such as a single door, a double door, or any other type of door.
Furthermore, the wiring space (first wiring space) and the second wiring space may have any shape as long as they are spaces capable of accommodating wiring therein.

Furthermore, in this hinge for a swing door, the support mounting portion has a first arc portion and is solid, and the interior portion has a second arc portion that is rotatable along the first arc portion, and the center points of the first arc portion and the second arc portion are pivotally supported, which is preferable because it allows for a simple configuration.

The first and second arc portions may be formed in a portion thereof, and it is preferable that the second arc portion be formed in a shape that matches the first arc portion and has the same curvature so that it can rotate along the first arc portion. Note that the second arc portion and the first arc portion of the interior portion do not necessarily need to slide.

Furthermore, it is necessary that each arcuate portion has a conceivable center point, and that a rotation axis is provided at each center point.
In this specification, the term "communicating" means that the spaces are connected in general patent terms.

With this hinge for a swing door, a wiring space that communicates with the embedded hinge door section is formed in the support mounting section, and if an interior section is present, a second wiring space that communicates with the wiring space in the support mounting section is formed in the interior section. Therefore, since the necessary wiring can be inserted using the wiring space, the swing door can be installed without using other parts such as conductive fittings, reducing the construction cost of the swing door and resulting in a structure with excellent design.

The present invention provides a hinge for swing doors that reduces the number of parts and contributes to improved design.

[Swing door]
The hinge 40 for a swing door is used by being attached to a swing door 20 (door).
For example, the hinged door 20 has a rectangular shape and is attached to a door attachment portion, which is a rectangular opening formed in the wall W.
Although not described in detail, upper and lower horizontal support frames (not shown) and left and right vertical support frames (only the left support frame 10 is shown) extend around the four sides of the door mounting portion (Figures 1 and 2).
The left support frame 10 is composed of an outer support frame 11 having an opening, and an inner support frame 12 having a box-shaped cross section that is inserted into the opening of the outer support frame 11.

A hinge 40 for a full-swing door is attached to two locations, above and below, on the vertical end face (hereinafter referred to as the "vertical end face 20a") at the end of the swing door 20, and the swing door 20 is attached to the inner support frame 12 via the hinge 40 for a full-swing door so that it can rotate freely.
At a predetermined height position on the upper and lower ends of the vertical butt end surface 20a of the hinged door 20, openings 20b are formed to accommodate the hinged door embedded portion 41 of the hinged door hinge 40.

[Structure of hinges for full-opening doors]
The hinge 40 for a swing door includes a swing door embedded portion 41, a vertical adjustment portion 42, a horizontal adjustment portion 43, an interior portion 44, a support shaft 45, and a support frame mounting portion 51 (FIGS. 3 and 4).

The hinged door recess 41 is a thin, rectangular casing with an open front and door mounting sections 41a protruding from the top and bottom ends. The hinged door recess 41 is inserted into the opening 20b in the vertical butt end 20a and attached to the door mounting section 41a with screws (not shown). The door mounting section 41a is covered with a cover plate 47 (reference numeral 31 denotes a screw used to attach the cover plate 47).

The vertical adjustment section 42 and horizontal adjustment section 43 are well-known elements and will not be described in detail, but they are inserted into the hollow section of the embedded hinged door section 41, and by adjusting the specified adjustment screws 42a and 43a, the vertical and horizontal positions of the embedded hinged door section 41 can be finely adjusted. The vertical adjustment section 42 and horizontal adjustment section 43 are inserted into the hollow section of the embedded hinged door section 41.

The interior portion 44 includes upper and lower sector plates 44a (second arc portions) with a central angle of approximately 90 degrees, a back plate 44c provided between the arc portions of the sector plates 44a, and side plates 44d provided between the radial sides of each sector plate 44a. A central hole 44b is formed in the main portion of each sector plate 44a.
The interior portion 44 is attached to the hinged door embedded portion 41 together with the vertical adjustment portion 42 and the horizontal adjustment portion 43 at the top and bottom by screws (not shown).

Furthermore, a wiring insertion portion 44e is opened at the joint between the back plate 44c and the side plate 44d (Figure 5). The interior portion 44 has open sides, and the area surrounded by the upper and lower fan-shaped plates 44a, the back plate 44c, and the side plate 44d forms a second wiring space 48 that communicates with the first wiring space 55 (wiring space) described below. Therefore, wiring inserted into the second wiring space 48 can be led out to the outside through the wiring insertion portion 44e.

The support frame mounting portion 51 has a solid sectorial pillar 52 with a central angle of approximately 90 degrees, a mounting plate 54 for mounting to the inner support frame 12, and a solid connector 53 provided between the sectorial pillar 52 and the mounting plate 54. The sectorial pillar 52 forms the first arc portion.

A vertical hollow portion 52a is formed in a main portion of the sectorial column 52. A support shaft 45 is inserted through the hollow portion 52a via bushings 32 inserted from above and below, with the top and bottom of the hollow portion 52a aligned with the central hole 44b of the interior portion 44, and the interior portion 44 is pivotally supported (freely) around the support shaft 45 along the support frame mounting portion 51. An attachment plate 54 of the support frame mounting portion 51 of the full-swing door hinge 40 is fitted into the fitting portion 12a of the inner support frame 12.
This allows the interior part 44 attached to the hinged door embedded part 41 to rotate along the fan-shaped pillar 52 of the support frame mounting part 51, and the hinged door 20 attached to the hinged door embedded part 41 is supported on a shaft so that it can rotate freely.
The reference numeral 33 denotes a washer provided on the upper surface of the bush 32 .

A first wiring space 55 is formed in the horizontal direction at approximately the vertical center of the support frame mounting portion 51. That is, the first wiring space 55 is an internal space provided between the sectorial column 52, the connector 53, and the mounting plate 54 (FIG. 5).
The mounting plate 54 has an opening 54a connected to the first wiring space 55, and the first wiring space 55 communicates with the hollow portion of the inner support frame 12 via this opening 54a. The end of the first wiring space 55 on the sectorial column 52 side also has an opening 52b, and the first wiring space 55 communicates with the second wiring space 48 of the interior part 44. The wiring insertion part 44e provided in the second wiring space 48 is connected to the inside of the hinged door 20, so the hollow portion of the inner support frame 12 communicates with the inside of the hinged door 20 via the first wiring space 55 of the support frame mounting part 51 and the second wiring space 48 of the interior part 44.

This structure allows wiring connected to the power source (neither shown) to be led to the inside of the hinged door 20 through the first wiring space 55 of the support frame mounting portion 51 and the second wiring space 48 of the interior portion 44, and connected to an electric lock (not shown).
In addition, two circular holes 52c are formed in the radial direction on the upper surface of the fan-shaped column 52 of the support frame mounting portion 51, and a rotation position control plate (not shown) can be inserted into these circular holes 52c.

[Effects of hinges for full-opening doors]
According to the present swing door hinge 40, the support frame mounting portion 51 and the interior portion 44 are formed with the first wiring space 55 and the second wiring space 48 that communicate with each other, so that the necessary wiring can be inserted using the first wiring space 55 and the second wiring space 48. Therefore, the swing door 20 can be mounted without using other parts such as conductive metal fittings, which reduces the construction cost of the swing door 20 and allows for a structure with excellent design.
