Abstract

PURPOSE:To obtain a door, by which the finger of a man is not broken even when the finger is caught in the door and which has high safety, by simple formation by forming a notched section forming a clearance in size larger than the thickness of the finger between the door closing side and a door mounting member under the state, in which the door is closed in an end face on the hinge side of the door. CONSTITUTION:A notched section 4 is formed towards the door closing side B from the corner section of the door opening side A in an end face 3 on the hinge side of a door 2. The notched section 4 is formed in an inclined plane 3a and formed at an angle of approximately 45 deg. to the surface of the door at that time. Consequently, when the door 2 is closed, a clearance 6 in size large than the thickness of the finger of a man is shaped on the door closing side B of the end face 3 on the hinge side. Accordingly, the door having high safety at low cost can be manufactured without mounting an additional member such as a protective material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safe door in which a finger or the like is not caught when opening and closing the door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a general door has a hinge-side end face 3 of the door 2 and a door frame 7 when the door 2 is opened.
There is a space 8 between and. Then, when the door 2 is closed with a finger or the like in the space 8, the finger is strongly sandwiched between the hinge-side end surface of the door 2 and the door frame 7. Especially, the width of the end face 3 on the hinge 1 side is significantly smaller than the width of the door 2,
It was a dangerous thing to catch a finger with extremely large force.
Therefore, as disclosed in Japanese Utility Model Laid-Open No. 58-93175 and Japanese Utility Model Laid-Open No. 58-9487, a door safety mechanism for preventing the above accident is formed by the end surface 3 of the door 2 and the door frame 7. It has been proposed that the space 8 to be covered is covered with a protective member so that the space 8 is not opened to the outside.

[0003]

In the case of the conventional technique disclosed in the above publication, as shown in FIG.
Is fixed to the door frame 7 at one end and to the closing side of the door 2 at the other end,
It has a slack that can follow the opening and closing of the door 2. Therefore, it is necessary to use a material such as elastic rubber or to bend a metal piece or the like for the protective material 11, and the material and its shape are limited. Moreover, the material like rubber cracks due to its expansion and contraction,
Further, the bending of the metal piece may cause metal fatigue and damage. Further, providing the protective member 11 is structurally complicated and is not preferable in terms of design.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide a highly safe door which has a simple structure and is not crushed by pinching a finger.

[0005]

The present invention relates to a door which is swingably attached to a door attaching member via a hinge,
A door provided with a cutout portion on the hinge-side end surface of the door to form a gap of at least the thickness of a person's finger between the door mounting member and the closed-door side of the hinge-side end surface in the closed state. . The cut-out portion of the hinge-side end surface is a sloped surface formed at an angle of about 45 degrees so as to widen the distance from the door mounting member toward the door closing side.

[0006]

According to the door of the present invention, even if a finger is sandwiched between the hinge-side end surface of the door and the door mounting member, a space about the thickness of the finger is formed when the door is closed. It was made so as not to be crushed. In particular, the inclined surface allows the finger to be pushed out, so that the fingertip is not crushed even if the fingertip is pinched toward the inner side between the hinge side end surface of the door and the door mounting member.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the door 2 of this embodiment
Is swingably attached to a door frame 7, which is a door attachment member, via a hinge 1. Here, shaft 1 of hinge 1 of door 2
The side where a is located and the door 2 is opened is referred to as a door opening side A, and the opposite side where the door 2 is closed is referred to as a door closing side B.

A cutout portion 4 is formed on the hinge-side end surface 3 of the door 2 from a corner portion of the open door side A toward a closed door side B, and the cutout portion 4 forms a slope 3a. There is. Since the slanted surface 3a is formed on the hinge-side end surface 3, even when the door 2 is closed, a gap 6 larger than the thickness of a human finger is formed on the door-closing side B of the end surface 3.
In the case of the door 2 having a normal size, this gap 6 has a slope of 45.
It can be obtained by setting the angle in degrees.

Next, the operation of the door 2 will be described. As shown in FIG. 2, the door 2 was completely closed with fingers in the space 8 formed between the hinge side end surface 3 of the door 2 and the door frame 7 formed when the door 2 was opened. In this case, since a gap 6 having a thickness equal to or larger than that of a human finger is formed between the hinge-side end surface 3 and the door frame 7,
The fingers are not crushed. In particular, if a finger is inserted deeply between the hinge-side end surface 3 of the door 2 and the door frame 7, the finger will be caught between the inner part of the slope 3a and the door frame 7, but the slope 3a Thus, the force acts so that the finger is pushed back into the space in front.

According to the door 2 of this embodiment, even if a finger is sandwiched between the hinge side end surface 3 of the door 2 and the door frame 7, the finger 2 is not crushed, and the inclined surface 3a pushes the finger outward. It works like this and is extremely safe.

As a modified example for forming the above-mentioned gap, as shown in FIG. 3, the cutout portion 4 having a thickness equal to or larger than that of the finger is formed by leaving the door-opening side A of the hinge-side end surface 3 thin. You can also use it. Further, as shown in FIG. 4, the hinge side end surface 3
May be cut in an arc shape.

[0012]

The door of the present invention is highly safe because it does not crush the door by pinching the finger between the end surface of the door and the door mounting member. Moreover, since the structure is simple and no additional member such as a protective member is provided, it can be provided at a low cost.
