Description

  The present invention relates to a hinge device used for combining various doors so as to be rotatable with respect to a door frame, and a door mechanism including such a hinge device, a door, and a door frame.

  There is a door device in which when a finger is sandwiched between a door and a door frame, the door is tilted to form a gap that becomes wider between the door and the door frame as it goes downward. Of the frame-side mounting piece and the door-side mounting piece that are assembled so as to be rotatable around a pin, the frame-side mounting piece is provided with a plurality of mounting holes for the door frame in addition to the uppermost mounting hole. Is a long hole in the lateral direction, and the door is tilted when a finger is caught around a screw fitting passed through the uppermost mounting hole and fixed to the door frame. (See Patent Document 1)

However, in such a door device, in order to allow tilting of the door, it is necessary to form a gap closed with a hollow seal member on the inner periphery of the door frame. In addition, the gap formed by the tilting of the door when a finger is pinched is a gap that widens as it goes downward. It was something that would end up.
JP 2006-2403 A

  The main problem to be solved by the present invention is that when a finger or the like is sandwiched between an end surface of the door on the side of the rotational assembly and the door frame, the finger or the like is further sandwiched without tilting the door. It is in the point not to attach.

In order to achieve the above object, in the present invention, the hinge device has the following configurations (1) to (5).
(1) a first hinge element attached to either the door or the door frame;
(2) a second hinge element that is rotatably combined with the first hinge element;
(3) a third hinge element that is slidably combined with the second hinge element and is attached to the other of the door and the door frame;
(4) holding means for preventing the slide movement,
(5) The holding force of the holding means is such that when a finger or the like is sandwiched between the door end face on the rotating assembly side and the door frame in the process of closing the door, a closing force greater than a predetermined magnitude is applied to the door. The size is such that the slide movement is allowed when the lens is acted upon.

  Usually, since the second hinge element and the third hinge element are integrated by the holding means, the door is rotated around the axis. When a finger or the like is sandwiched between the door end face on the pivot assembly side and the door frame in the process of closing the open door, the door is retained if a force in the closing direction greater than the predetermined size is applied to the door. The distance between the second hinge element and the first hinge element because the holding of the second hinge element and the third hinge element by the means is released and the third hinge element slides away from the second hinge element. The end surface of the door on the side where the door is pivoted can be separated from the inner surface of the door frame without further narrowing the door, thereby preventing the fingers and the like sandwiched from being pressed further.

  If the second hinge element is provided with a rod-like body and the third hinge element is provided with a through-hole through which this rod-like body is passed, when the holding means is released, the third hinge element is used as a guide. The lever can be slid along the length of the lever and the door can be moved in the same direction.

  The third hinge element is provided with a cylindrical body arranged to communicate with the through hole on the side not facing the second hinge element, and the sliding movement of the third hinge element is provided at the tip of the rod-shaped body If the restriction is restricted at the position where the tip of the cylinder abuts, the third hinge element and the second hinge element are usually integrated by the holding means after the pinching of the finger or the like is eliminated. It can be easily returned to the state.

  The holding means is composed of an adsorbing portion provided with a magnet provided in one of the second hinge element and the third hinge element, and an adsorbed portion provided in the other and adsorbed by the magnet to the adsorbing portion. In this case, normally, the second hinge element and the third hinge element can be integrated by adsorbing the attracting part to the attracted part by the magnetic force of the magnet. In addition, when a finger or the like is sandwiched between the door end face on the pivot assembly side and the door frame in the process of closing the opened door, a closing direction force greater than the predetermined magnitude is applied to the door. The adsorption can be released and the third hinge element can be slid out of the second hinge element. When the pinch of the finger or the like is resolved, the suctioned part is again attracted to the attracted part, so that the normal state can be easily restored.

  In a door mechanism in which a door is pivotably combined with a door frame via these hinge devices, the door is normally opened and closed around an axis that combines the first hinge structure and the second hinge structure. The operation is performed regularly, and when a finger is caught between the one end surface and the inner surface of the door frame in the process of closing the opened door, the door is rotated so as not to press the finger any more. You can switch to that slide movement.

  In the hinge device according to the present invention, when a finger or the like is sandwiched between the end surface of the door on the rotating assembly side and the door frame, the door is rotated without tilting the door. It is possible to switch the movement to a direction in which the one end face is moved away from the finger so that the finger is not further compressed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

  1 to 6 show a hinge device H and a door mechanism according to one of the best modes for carrying out the present invention, and FIG. 1 shows each of the components constituting the hinge device H. FIG. 2 shows a state in which the door D is closed in a normal state in a plan view, FIG. 3 shows a state in which the door D is opened in a normal state, and FIG. FIG. 5 shows a state in which the main part of the hinge device H in a normal state is viewed from the front in a cross-sectional view, and FIG. 6 shows a state such as the finger Z. The main part of the hinge device H when the is sandwiched is shown as a cross-sectional view seen from the front.

  The hinge device H according to this embodiment is used for combining various doors D with respect to the door frame F so as to be rotatable. The door mechanism according to this embodiment includes the hinge device H, the door D, and the door frame F.

Such a hinge device H includes:
(1) First hinge element 1
(2) Second hinge element 2
(3) Third hinge element 3
(4) A shaft 4 in which the first hinge element 1 and the second hinge element 2 are rotatably combined.
(5) Holding means 5
It is comprised including.

  The hinge device H typically includes a first end surface Da extending in the vertical direction of the door D and an inner surface Fb directed inward of the opening Fa closed by the door D extending in the vertical direction of the door frame F. The door D is assembled to the door frame F so as to be rotatable. When the door D is completely closed, the one end surface Da of the door D faces the inner surface Fb of the door frame F with a slight gap. Such a hinge device H normally regularly opens and closes the door D around a shaft 4 to be described later, and in the process of closing the opened door D, the one end face Da and the inner face Fb of the door frame F When the finger Z or the like is sandwiched between them, the rotation of the door D is switched to the movement in the direction in which the one end face Da is moved away from the inner surface Fb of the door frame F so that the finger Z or the like is not strongly pressed.

  Such a hinge device H is provided from one place to several places between the door D and the door frame F according to the size of the door D and the like, and the door D and the door frame F constitute a door mechanism. In the door mechanism configured as described above, the door D is normally opened and closed around a shaft 4 which will be described later, and the one end face Da and the door are closed in the process of closing the opened door D. When a finger Z or the like is sandwiched between the inner surface Fb of the frame F, the door D is rotated so that the one end surface Da is moved away from the inner surface Fb of the door frame F so that the finger Z or the like is not further compressed. Switch to move.

  The first hinge element 1 is attached to either the door D or the door frame F. In the illustrated example, the first hinge element 1 is attached to the inner surface Fb of the door frame F by screws.

  The second hinge element 2 is combined with the first hinge element 1 so as to be rotatable by a shaft 4. In the illustrated example, the axis 4 is an axis along the vertical direction. The hinge device H is positioned between the door D and the door frame F so that the shaft 4 protrudes forward from one surface of the door D on the rotational assembly side of the door.

  The third hinge element 3 is combined with the second hinge element 2 so as to be slidable and attached to the other of the door D and the door frame F. In the illustrated example, the third hinge element 3 is attached to the one end face Da of the door D by screwing. (A screw hole for this purpose is indicated by reference numeral 32.) The third hinge element 3 and the second hinge element 2 are usually integrated with the other surfaces 2 ", 3" overlapped by a holding means 5 described later. Therefore, the second hinge element 2 is formed with a screw through hole 23 for screwing the third hinge element 3 to the end face Da of the door D on the rotating assembly side. In the process of closing the opened door D, when a finger Z or the like is sandwiched between the one end surface Da and the inner surface Fb of the door frame F, this holding is performed when a predetermined closing direction force is applied to the door D. The holding of the means 5 is released and the third hinge element 3 is slid together with the door D in a direction away from the second hinge element 2 as a whole.

  The holding means 5 holds both of them so that the sliding movement of the third hinge element 3 from the second hinge element 2 is not normally performed. In other words, the holding means 5 normally has the second hinge element 2 and the third hinge element 3 in an integrated state with a fixed holding force, and the rotation of the door D is regular around the shaft 4. It's what keeps you done.

  The holding force of the holding means 5 is such that the end face Da (specifically, the one end face Da) and the door frame F (specifically, the inner face Fb) of the door D in the process of closing the door D are closed. Allow the third hinge element 3 to slide from the second hinge element 2 when a closing force greater than a predetermined magnitude is applied to the door D when a finger Z or the like is sandwiched between It is the size to do.

  Usually, since the second hinge element 2 and the third hinge element 3 are integrated by the holding means 5, the door D is rotated around the shaft 4. (FIGS. 2 to 3) In the process of closing the opened door D, when a finger Z or the like is sandwiched between the end face Da on the rotating assembly side of the door D and the door frame F, the door D is larger than the predetermined size. When the force in the closing direction is applied, the holding means 5 releases the holding of the second hinge element 2 and the third hinge element 3, and the third hinge element 3 slides away from the second hinge element 2. Therefore, the end face Da on the rotating assembly side of the door D can be separated from the inner surface Fb of the door frame F without further reducing the distance between the second hinge element 2 and the first hinge element 1. It is possible to prevent the fingers Z and the like sandwiched between them from being further compressed. (Fig. 4, Fig. 6)

  In the example shown in the figure, the holding means 5 is provided with a suction part 50 having a plate-like magnet 50a provided in the third hinge element 3 and a target attached to the suction part 50 by the magnet 50a. The suction portion 51 is configured.

  Thereby, in this example, the 2nd hinge element 2 and the 3rd hinge element 3 can be integrated by the adsorption | suction to the to-be-adsorbed part 51 of the adsorption | suction part 50 normally by the magnetic force of the magnet 50a. Further, in the process of closing the opened door D, when a finger Z or the like is sandwiched between the end face Da on the rotating assembly side of the door D and the door frame F, the door D has a force in the closing direction greater than the predetermined size. When the operation is performed, the adsorption can be released and the third hinge element 3 can be slid out of the second hinge element 2 and moved away. When the pinching of the finger Z or the like is eliminated, it is possible to easily return to the normal state by adsorbing the adsorbing unit 50 to the adsorbed unit 51 again.

  In this example, the first hinge element 1 has a plate portion 10 attached to the inner surface Fb so that one surface is in contact with the inner surface Fb of the door frame F, and a cylindrical shaft on one side of the plate portion 10 extending in the vertical direction. And a pipe portion 11 provided integrally so as to be arranged in the vertical direction. The pipe portion 11 is formed from the lower end of the plate portion 10 to a position approximately in the middle in the vertical direction. The plate portion 10 is formed with a screw through hole 12 to be fixed to the door frame F. A shaft 4 is passed through the pipe portion 11. In this example, the pipe portion 11 includes an upper portion 11a having a large inner diameter and a lower portion 11b having a small inner diameter, and a step surface 11c facing upward is formed between the upper portion 11a and the lower portion 11b. A flange 40 is formed in the middle of the shaft 4, and the shaft 4 is inserted into and supported by the pipe portion 11 so as to be hooked on the stepped surface 11c from above.

  Further, the second hinge element 2 has a substantially rectangular plate portion 20 that is long in the vertical direction, and a protruding piece that is continuous with the plate portion 20 on the upper side of one side along the vertical direction of the plate portion 20 in the vertical direction. And a pipe portion 21 formed and formed in a cylindrical shape along the cylinder axis. The upper part of the shaft 4 supported by the first hinge element 1 as described above is inserted into the pipe portion 21 of the second hinge element 2 from below. The lower part of the pipe part 21 enters the inside of the upper part 11 a of the pipe part 11 of the first hinge element 1, and the connecting base part 21 a of the pipe part 21 is stored in the notch 11 d of the pipe part 11.

  The plate portion 20 of the second hinge element 2 is provided with a through hole 22, and a shaft 60 as a rod-like body 6 having a round bar shape having a head portion 61 is connected to the head portion 61 from the one surface 2 ′ side of the plate portion 20. Is passed through the through-hole 22 to the position where it is caught, and the head portion 61 is fixed to the plate portion 20 by welding or the like. That is, the second hinge element 2 includes a rod-like body 6 that protrudes from the other surface 2 ″ side of the plate portion 20 in a direction substantially orthogonal to the other surface 2 ″.

  A screw hole 62 extending in a direction perpendicular to the axis of the shaft 60 and opened at both sides in the diametrical direction of the shaft 60 is formed at the tip of the shaft 60 (the tip protruding from the plate portion 20). A screw 63 a serving as a restricting portion 63 is screwed to 62 so that both ends of the screw protrude from the screw holes 62.

  Further, the third hinge element 3 has a substantially rectangular plate portion 30 that is long in the vertical direction, and a through hole 31 having a round hole shape is formed at a position approximately in the middle of the plate portion 30 in the length direction. Is formed. In the illustrated example, the hinge device H includes a cylindrical body 7 that is opened on an end surface Da of the door D and is inserted into a mounting hole Db that extends in the left-right direction of the door D on the rotating assembly side of the door D. One end of the cylinder 7 inserted into the attachment hole Db communicates with the through hole 31 on the one surface 3 ′ side of the plate portion 30 of the third hinge element 3. In this example, an outer collar 70 is formed at one end of the cylinder 7, and the outer collar 70 is abutted against one surface 3 ′ of the plate portion 30 of the third hinge element 3. .

  In the example shown in the figure, rising portions 30a are formed on the four sides of the plate portion 30 on the other surface 3 ″ side of the plate portion 30 and a through hole is formed on the other surface 3 ″ side of the plate portion 30. Adsorption portions 50 are respectively formed on the upper and lower sides with 31 interposed therebetween. The adsorbing portion 50 includes a plate-like magnet 50a having a through-hole 50a ′ at the center, an attachment plate portion 50c on one of the magnetic pole faces of the plate-like magnet 50a, and the left and right edges of the attachment plate portion 50c. And a yoke 50b having a rising plate portion 50d that rises integrally toward the other side of the magnetic pole surface of the magnet 50a. In the illustrated example, a communication hole 50e communicating with the through hole 50a 'of the plate magnet 50a is formed in the yoke 50b, and a screw 50f passed through the through hole 50a' of the plate magnet 50a and the communication hole 50e is connected to the yoke 50b. The suction part 50 is provided in the plate part 30 by screwing it into the screw hole 33 of the plate part 30 first. The protruding end of the rising plate portion 50d of the yoke 50b of the attracting portion 50 is located slightly in front of the other magnetic pole surface of the plate magnet 50a, and the rising portion 30a of the plate portion 30 of the third hinge element 3 is located. It is located slightly ahead of the tip. In a normal state, the rising plate portion 50d of the yoke 50b of the suction portion 50 is in contact with and attracted to the other surface 2 'of the second hinge element 2. That is, in this example, the portion that receives such suction in the second hinge element 2 functions as the attracted portion 51.

  In this example, the second hinge element 2 and the third hinge element 3 are usually integrated by the holding means 5 in a superposed manner with the other surfaces 2 ″ and 3 ″ in proximity to each other. (Figure 2)

  When a finger Z or the like is sandwiched between the end face Da on the rotating assembly side of the door D and the inner face Fb of the door frame F, the door D is held when a closing force greater than a predetermined magnitude is applied to the door D. The holding of the means 5 is released, and the third hinge element 3 is slid along the length of the rod-shaped body 6 with the rod-shaped body 6 as a guide, and the door D is also moved in the same direction. (Fig. 4)

  In this example, the third hinge element 3 and the second hinge element 2 pass the rod-like body 6 passed through the through hole 31 of the third hinge element 3 through the cylindrical body 7, and then the tip of the rod-like body 6. These are combined by providing a restricting portion 63. Normally, a gap s is provided between the tip of the cylindrical body 7 of the third hinge element 3 and the restricting portion 63 provided at the tip of the rod-like body 6 of the second hinge element 2 (FIG. 2). The movement stops at a position where the tip of the cylindrical body 7 comes into contact with the restricting portion 63. Thus, after the pinching of the finger Z or the like is eliminated, the normal state in which the third hinge element 3 and the second hinge element 2 are integrated by the holding means 5 can be easily restored.

  The main parts of the first hinge element 1, the second hinge element 2, and the third hinge element 3 are typically made of a highly rigid material such as metal.
