detailed description

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

1 to 9 show the first embodiment of the present invention. First, the outline structure of the hinge device A according to the present embodiment will be described. As shown in FIG. 1 , the hinge device A has a bottom pad 1 , a mounting part 2 , a main part 3 and a coupling mechanism 4 .

The bottom pad 1 is fixed to a portion near the opening on the inner surface of a base body (not shown). In the present embodiment, it is fixed to the front end portion of the left inner surface of the base with the front opening. In addition, in order to easily understand each structure of the hinge device A, the base body is described using front, rear, left, right, and up and down (front, back, left, right, and up and down shown in FIG. 2 ). Of course, the hinge device A is not limited to this directionality.

The mounting part 2 is fixed on the back of the door and window (not shown in the figure), and in this embodiment, it is arranged on the left side of the back of the door and window when it is in the closed position, corresponding to the bottom pad 1 being arranged on the left inner surface of the base body. department.

The mounting member 2 is rotatably coupled to the front end portion of the main body member 3 via a pair of link rods 5A, 5B. That is, as shown in FIG. 4 , one ends of the links 5A, 5B are rotatably coupled to the mounting member 2 via shaft portions 6 a , 6 b of the substantially “U”-shaped coupling shaft 6 , respectively. The other ends of the connecting rods 5A, 5B are rotatably coupled to the front end of the main body 3 via shafts 7A, 7B, respectively. The installation part 2 and the main body part 3 can also be rotatably coupled directly, or the installation part 2 and the main body part 3 can be rotatably connected through more than three connecting rods. The main body 3 is detachably mounted on the bottom pad 1 through the coupling mechanism 4 . As a result, the door and window are attached to the base so as to be rotatable in the horizontal direction via the hinge device A. As shown in FIG.

In addition, one end portion 8a of a coil spring (additional force unit) 8 that is overlaid on a shaft 7C by one end portion 8a of the connecting rod 5A of the two connecting rods 5A and 5B is provided with a rotational force through the spring holder 9A, while the other connecting rod 5B is A rotational force is applied by the other end portion 8b of the coil spring 8 via the spring holder 9B. Then, relying on the rotation additional force of the coil spring 8, when the door and window is between the closed position and the middle position between the open position and the closed position, the door and window is interposed between the connecting rods 5A, 5B and is subjected to an additional rotational force toward the closed position side, while When the door and window are between the middle position and the open position, the door and window are provided with a rotational force toward the open position through the connecting rods 5A and 5B. It is also possible to utilize other known rotational force adding structures to add rotational force to the door and window sash. In addition, the rotational force adding mechanism is not necessarily provided.

A rotation buffer mechanism 10 is provided on the shaft 7B. The rotation buffer mechanism 10 is used to suppress the rotation speed at least at a low speed when the door and window leaf rotates from the middle position to the closed position side. Since the rotation buffer mechanism 10 is irrelevant to the present invention, the description of the rotation buffer mechanism 10 is omitted.

The structure of the lower hinge device A is described in more detail below. As shown in FIGS. 2 and 3 , the bottom pad 1 has a base plate 11 , a first movable member 12 and a second movable member 13 .

The substrate 11 is fixed to the part near the opening on the inner surface of the base, and in this embodiment, is fixed to the front end on the left side of the base with the front opening by fixing means such as screws (not shown). In addition, in order to easily understand each structure of the hinge device A, the base body is described using front, rear, left, right, and up and down (front, back, left, right, and up and down shown in FIG. 2 ). Of course, the hinge device A is not limited to this directionality.

A protruding portion 11 a having a substantially U-shaped cross-section is provided on the rightward front surface of the substrate 11 , and its longitudinal direction faces the front-rear direction. A limiting hole 11b extending in the front-rear direction is formed at the center of the rightward front end surface of the protruding portion 11a, and a limiting groove 11c extending in the vertical direction is formed at the rear end of the front end surface. A locking recessed portion 11d is formed on the forward front end surface of the protruding portion 11a. A locking hole 11e penetrating through the protrusion 11a in the vertical direction is formed at the rear end of the protrusion 11a. The locking hole 11e is arranged behind the stopper groove 11c.

The first movable member 12 has a substantially U-shaped cross section, and its longitudinal direction is arranged in the front-rear direction. Inside the first movable member 12, the protruding portion 11a of the base plate 11 is inserted. The vertical distance between the two inner surfaces of the first movable member 12 is larger than the vertical distance between the two outer surfaces of the protrusion 11a. Therefore, the first movable member 12 can move relative to the base plate 11 in the vertical direction within the range of the difference between the distance between the two inner surfaces of the first movable member 12 and the distance between the two outer surfaces of the protruding portion 11a.

Shafts 14 and 15 are inserted through the front end and the rear end of the first movable member 12 , with their longitudinal directions facing up and down. The shaft 14 is engaged with the locking recess 11d, and the shaft 15 is inserted through the locking hole 11e. Accordingly, the first movable element 12 is installed on the base plate 11 and cannot move in the front-back direction and the left-right direction. Therefore, the first movable member 12 can only move in the up and down direction relative to the base plate 11 .

The position of the first movable member 12 in the vertical direction relative to the base plate 11 is adjusted by a first position adjusting mechanism. That is, on the right side of the first movable part 12, an oblong guide hole 12a extending in the front-rear direction is formed, and the flat plate-shaped position adjusting member 16 is inserted into the guide hole 12a and can be positioned in the direction of the guide hole 12a length ( forward and backward direction) and cannot move in the up and down direction.

On the rightward surface of the position adjusting member 16, first and second cylindrical portions 16a, 16b are formed. The 1st and 2nd cylindrical parts 16a and 16b are mutually spaced apart in the front-back direction, and each axis|shaft is arrange|positioned toward the left-right direction. The diameters of the first and second cylindrical parts 16a, 16b can be expanded and contracted because there are two cutouts in the circumferential direction of the respective peripheral wall parts. Each of the holes inside the first and second cylindrical portions 16 a and 16 b penetrates the position adjusting member 16 . Peaks and valleys extending in the left-right direction are alternately formed in the circumferential direction on the inner peripheral surfaces of the first and second cylindrical parts 16a, 16b.

The head portion 17a of the first adjustment shaft 17 is inserted into the first cylindrical portion 16a, and peaks and valleys extending in the left-right direction are alternately formed on the outer peripheral surface of the head portion 17a. The peaks and valleys are respectively fitted into the valleys and peaks of the first cylindrical portion 16a, whereby the rotation of the first adjustment shaft 17 relative to the position adjusting member 16 is prevented. However, since the diameter of the first cylindrical portion 16a can be expanded and contracted, the first adjustment shaft 17 can rotate while expanding and contracting the diameter of the first cylindrical portion 16a when a rotational force of a predetermined value or more acts.

The left end surface of the head portion 17a of the first adjustment shaft 17 faces the front end surface (rightward surface) of the protruding portion 11a of the base plate 11, and a first eccentric shaft (not shown) is formed on the left end surface. This 1st eccentric shaft is arrange|positioned so that the axis|shaft may be spaced apart from the axis|shaft of the head part 17a, and may be parallel. That is, the first eccentric shaft is disposed at a position eccentric with respect to the head portion 17a. The first eccentric shaft is inserted into the limiting hole 11b, and can move along its length direction (front-back direction) but cannot move along its width direction (up-down direction). Therefore, when the first adjustment shaft 17 is rotated, the first eccentric shaft moves in the front-rear direction in the limiting hole 11b, and the head 17a moves in the up-down direction. As a result, the position adjusting member 16 moves in the vertical direction, and furthermore, the first movable member 12 moves in the vertical direction relative to the base plate 11 . That is, position adjustment is possible in the up and down directions. Of course, the position adjustment amount of the first movable member 12 is an amount corresponding to the rotation amount of the first adjustment shaft 17 .

The second movable member 13 is provided on the first movable member 12 . The second movable member 13 has a substantially U-shaped cross section, and the first movable member 12 is inserted therein. The distance between the two inner surfaces in the vertical direction of the second movable member 13 is set to be the same as the distance between the two outer surfaces in the vertical direction of the first movable member 12 . Therefore, the second movable member 13 cannot move relative to the first movable member 12 in the vertical direction. Therefore, when the first adjusting shaft 17 is rotated to adjust the position of the first movable member 12 in the vertical direction, the second movable member 13 is adjusted in the vertical direction together with the first movable member 12 .

The second movable member 13 can move in the front-rear direction and the left-right direction relative to the first movable member 12 . The second movable member 13 is adjusted in position relative to the first movable member 12 in the front-rear direction by the second position adjusting mechanism. That is, a through-hole 13a is formed in the second movable member 13 in the left-right direction, and the second cylindrical portion 16b of the position adjusting member 16 is fitted into the through-hole 13a so as not to move in the radial direction. Therefore, when the position adjusting member 16 moves in the front-back direction, the second movable member 13 also moves in the front-back direction.

The head part 18a of the 2nd adjustment shaft 18 is inserted in the 2nd cylindrical part 16b. The diameter of the second cylindrical portion 16b can be expanded and contracted by forming two notched portions in the circumferential direction. In addition, peaks and valleys extending in the left-right direction are alternately formed in the circumferential direction on the inner peripheral surface of the second cylindrical portion 16b and the outer peripheral surface of the head portion 18a. Therefore, the head portion 18a can rotate within the second cylindrical portion 16b when a rotational force of a predetermined magnitude or more acts. In other words, the head 18a is maintained at a constant rotational position without rotating unless a rotational force greater than a predetermined magnitude acts.

The left end surface of the head portion 18a faces the front end surface of the protruding portion 11a of the base plate 11, and a second eccentric shaft (not shown) is formed on the left end surface. This 2nd eccentric shaft is arrange|positioned so that the axis|shaft may be spaced apart from the axis|shaft of the head part 18a, and may be parallel. That is, the second eccentric shaft is disposed at a position eccentric with respect to the head portion 18a. The second eccentric shaft is inserted into the limiting groove 11c, and can move along its length direction (up-and-down direction) but cannot move along its width direction (front-rear direction). Therefore, when the second adjustment shaft 18 is rotated, the second eccentric shaft moves in the vertical direction in the limiting groove 11c, and the head 18a moves in the front-back direction. As a result, the position adjusting member 16 moves in the front-rear direction, and the second movable member 13 moves in the front-rear direction relative to the first movable member 12 . Accordingly, the position of the second movable member 13 is adjusted in the front-rear direction relative to the base plate 11 . Of course, the position adjustment amount of the second movable member 13 in the front-rear direction corresponds to the rotation amount of the second adjustment shaft 18 .

In addition, the first cylindrical portion 16a of the position adjusting member 16 is fitted into the through-hole 13b formed in the second movable member 13, and cannot move in the radial direction thereof. Therefore, when the second movable member 13 moves in the front-back direction, the position adjustment member 16 and the first adjustment shaft 17 also move in the front-back direction. Here, the position adjusting member 16 only moves in the front-rear direction in the guide hole 12a, and the first adjustment shaft 17 only moves in the front-rear direction in the first eccentric shaft in the limiting hole 11b. Therefore, even if the position adjustment member 16 and the first adjusting shaft 17 move in the front-back direction as the second movable member 13 moves in the front-rear direction, the first movable member 12 will not move in the front-rear direction.

A long hole 13c extending in the front-rear direction is formed at the rear end portion of the second movable member 13 . The above-mentioned shaft 15 is inserted through the long hole 13c in a manner movable in the lengthwise direction of the long hole 13c and immovable in the width direction (right-left direction) and rotatable. Therefore, the tip portion of the second movable member 13 can rotate in the horizontal direction (left-right direction) around the shaft 15 . In addition, the length of the elongated hole 13c in the front-rear direction is set to a length that does not interfere with the position adjustment of the second movable member 13 relative to the first movable member 12 in the front-rear direction.

An adjusting screw 19 with an axis facing the left and right directions is screwed to the front end (left end) of the first movable member 12 . The head portion 19 a of the adjustment screw 19 is rotatably engaged with the front end portion of the second movable member 13 . Moreover, the head part 19a can move in the front-back direction with respect to the 2nd movable body 13, but cannot move in the left-right direction. Therefore, when the adjustment screw 19 is rotated in the forward and reverse directions, the second movable member 13 rotates in the horizontal direction centering on the shaft 15, and the front end of the second movable member 13 is adjusted in the left and right direction relative to the first movable member 12. , and then the position is adjusted relative to the base plate 11 in the left-right direction.

As mentioned above, the front end of the second movable member 13 can be adjusted in front, rear, left, right, and up and down directions relative to the base plate 11 or even the base body. The second movable part 13 can also be directly arranged on the base body in a fixed position. At this time, the second movable part 13 just becomes a bottom pad.

The main part 3 is detachably mounted on the second movable part 13 of the bottom pad 1 through the coupling mechanism 4 . That is, as shown in FIGS. 2 and 3 , a first engagement recess 41 and a second engagement recess 42 are respectively provided on both end surfaces in the front-rear direction of the second movable member 13 . The first and second engaging recesses 41 and 42 are arranged at substantially the same position in the left-right direction and in the up-down direction. However, the first and second engaging recesses 41 and 42 may be arranged at different positions in the left-right direction and/or in the up-down direction. When the first and second engagement recesses 41, 42 are arranged at different positions in the left-right direction, the first engagement recess 41 may be arranged on the right side of the second engagement recess 42 or vice versa. side.

The first engagement recess 41 has side surfaces on both sides in the left-right direction, a bottom surface at a rear end, and is opened forward. On the other hand, the second engaging recess 42 has side surfaces on both sides in the left-right direction, has a bottom surface at the front end, and is open toward the rear.

A first inclined surface 43 is formed on the front end surface of the second movable member 13 . The first inclined surface 43 is inclined so that the front end (left end in FIG. 1 ) is located on the left side (lower side in FIG. 1 ) than the rear end. The first inclined surface 43 is arranged on the right side of the first engaging recess 41 . The front end of the first inclined surface 43 is smoothly connected to the end of the opening on the right side (upper side in FIG. 1 ) of the first engagement recess 41 via an arc surface with a small radius of curvature. The front end portion of the first inclined surface 43 may directly intersect the right side of the first engaging recess 41 .

A second inclined surface 44 is formed on the rear end surface of the second movable member 13 . The second inclined surface 44 is inclined such that its rear end (right end in FIG. 1 ) is on the left side (lower in FIG. 1 ) than the top end, that is, it is inclined opposite to the first inclined surface 43 . The second inclined surface 44 is arranged on the right side with respect to the second engaging recess 42 . The rear end portion of the second inclined surface 44 is smoothly connected to the end portion on the opening side of the right side surface of the second engaging recess 42 via an arc surface with a small radius of curvature. The rear end portion of the second inclined surface 44 may directly intersect the right side of the second engaging recess 42 .

A stop surface 45 is formed on the rear end surface of the second movable member 13 . The stop surface 45 extends rightward from the rear end of the second inclined surface 44 to the rightward top end surface of the second movable member 13 . The stop surface 45 is inclined with respect to the base line described later (in this embodiment, the base line extends substantially horizontally in the front-rear direction.) The right end portion is slightly in front of the left end portion, but it may also be inclined in the opposite direction, or may be opposite to each other. The baseline is vertical. The stop surface 45 may not be formed.

A first engaging shaft (first engaging portion) 46 whose longitudinal direction faces the vertical direction is fixedly disposed on the front end portion of the main body 3 . The first engagement shaft 46 can be inserted into the first engagement recess 41, and can be inserted backward from the opening until it abuts against the bottom surface. The movement of the first engagement shaft 46 in the left and right direction is prevented by the left and right side surfaces of the first engagement recess 41 , and the rearward movement is prevented by the bottom surface of the first engagement recess 41 . Therefore, when the first engaging shaft 46 is engaged with the first engaging recess 41 , the front end of the main body 3 is locked and cannot move in the left-right direction and backward relative to the second movable member 13 .

The support shaft 47 whose longitudinal direction is facing the up-down direction is fixedly arranged on the rear end of the main body 3 . The operating member 48 is rotatably supported by the support shaft 47 . The operating member 48 is rotatable between the initial position shown in FIGS. 6 to 8 and the limit position after rotating a given angle counterclockwise from the position shown in FIG. 9 . The operating member 48 is biased by a coil spring (additional force unit) 49 wrapped around the support shaft 47 in a direction (clockwise in FIG. 1 ) from the limit position to the initial position. Before the main body 3 is attached to the second movable member 13 , the operation member 48 is in the initial position by the coil spring 49 .

A second engagement shaft (second engagement portion) 50 whose longitudinal direction is vertically oriented is provided on the operation member 48 so as to be fixed in position. The second engagement shaft 50 is arranged on the left side of the support shaft 47 . Moreover, the second engagement shaft 50 is arranged at a certain part of the operating member 48 at the initial position, and this part refers to the direction of the tangent line of the rotation circle of the operating member 48 when it rotates between the initial position and the limit position, and generally faces the front-rear direction. part. Therefore, when the operating member 48 rotates between the initial position and the extreme position, the second engaging shaft 50 basically moves in the front-rear direction. Of course, when the operating member 48 rotates from the initial position to the limit position side, the second engaging shaft 50 moves backward, and when the operating member 48 rotates from the limit position to the initial position side, the second engaging shaft 50 moves forward.

In addition, in order to form a structure in which the second engaging shaft 50 moves in the front-rear direction when the operating member 48 rotates, in this embodiment, it is arranged so that when the operating member 48 is at the initial position, the second engaging shaft 50 is positioned at a position lower than that of the support shaft 47. To the left and slightly to the rear. However, the second engagement shaft 50 is not necessarily arranged in this way, and may be arranged at the same position as the support shaft 47 in the front-rear direction or slightly front side as long as it is arranged on the left side of the support shaft 47 .

The second engagement shaft 50 may also be directly provided on the main body 3 so as to be movable in the front-rear direction. In this case, the coil spring 49 may be replaced with a force-adding means such as a spring that biases the second engaging shaft 50 facing forward.

The second engagement shaft 50 can be inserted into the second engagement recess 42, and can be inserted forward from the open portion until it abuts against the bottom surface. In the engaged state of inserting the second engagement recess 42 until it abuts against the bottom surface The movement of the second engaging shaft 50 in the left and right direction is prevented by the left and right sides of the second engaging recess 42 , and the movement forward is prevented by the bottom surface of the second engaging recess 42 . Therefore, when the second engaging shaft 50 is engaged with the second engaging recess 42 , the rear end of the main body 3 is locked and cannot move in the left-right direction and forward relative to the second movable member 13 . In addition, in the engaged state where the second engaging shaft 50 abuts against the bottom surface of the second engaging recess 42 , the operating member 48 is at an engaging position slightly before the initial position in the direction from the extreme position to the initial position. Therefore, the second engaging shaft 50 is maintained at the engaging position by the additional force of the coil spring 49 .

As shown in FIG. 1 , when the second engagement shaft 50 is engaged with the second engagement recess 42 , the support shaft 47 abuts against the stop surface 45 through the coil spring 49 , and the main body 3 cannot move forward. Therefore, in the state where the second engagement shaft 50 is engaged with the second engagement recess 42, even if the main body 3 is pushed forward, the second engagement shaft 50 will not be rearwardly faced by the bottom of the second engagement recess 42. When moving, the operating member 48 will not rotate to the limit position side against the rotation additional force of the coil spring 49 . Furthermore, since the main body 3 does not move forward, the first engagement shaft 46 does not come out of the first engagement recess 41 forward. Therefore, the first and second engagement shafts 46 and 50 are maintained in a state of being engaged with the first and second engagement recesses 41 and 42, respectively. Therefore, as long as the operating member 48 is not rotated from the engaging position to the limit position side, the main body member 3 will not be separated from the second movable member 13 . From this, it can be seen that the support shaft 47 also serves as the abutting portion, and the stop surface 45 and the support shaft 47 constitute a stop mechanism.

The first inclined surface 43, the second inclined surface 44, the first engagement shaft 46, and the second engagement shaft 50 are arranged so as to satisfy the following conditions. This condition refers to the condition that the first and second engaging shafts 46 and 50 can simultaneously abut against the first and second inclined surfaces 43 and 44 when the operating member 48 is at the initial position as shown in FIG. 6 .

In addition, the first and second inclined surfaces 43 and 44 are formed so as to satisfy the following angular relationship. That is, in a state where the first and second engaging shafts 46 and 50 are in contact with the first and second inclined surfaces 43 and 44, respectively, the contact point connecting the first engaging shaft 46 and the first inclined surface 43 and the second 2. When the straight line at the point of contact between the engaging shaft 50 and the second inclined surface 44 is the base line, the angle of inclination of the first inclined surface 43 relative to the base line is set to be larger than the angle of inclination of the second inclined surface 44 relative to the base line. For example, the inclination angle of the first inclined surface 43 is set to about 30° to 45°, and the inclination angle of the second inclined surface 44 is set to about 15° to 25°.

Here, in a state where the first and second engagement shafts 46, 50 are in contact with the first and second inclined surfaces 43, 44, respectively, when the main body 3 is mounted on the bottom pad 1, the main body 3 is placed on the When moving toward the bottom pad 1 in the horizontal plane, the base line is perpendicular to the moving direction of the main body 3 . Therefore, the angular relationship of the first and second inclined surfaces 43, 44 with respect to the base line can also be expressed in this way: the inclination angle of the first inclined surface 43 relative to the main body part 3 is set to be larger than that of the first inclined surface 43 in the direction of movement. 2. The inclination angle of the inclined surface 44 with respect to the same direction is small. It should be pointed out that the moving direction of the main body 3 is affected by human hands, and may not necessarily be perpendicular to the baseline, and sometimes inclines in the range of several to ten degrees relative to the perpendicular direction. Therefore, the relationship between the inclination angles of the first and second inclined surfaces 43, 44 should be more realistically defined as: the inclination angle of the first inclined surface 43 is set to Smaller than the inclination angle of the second inclined surface 44; or, relative to the direction approximately perpendicular to the moving direction of the main body 3, the inclination angle of the first inclined surface 43 is set to be larger than the inclination angle of the second inclined surface 44 . Taking this point into consideration, it is preferable that the inclination angle of the first inclined surface 43 is more than ten degrees larger than the inclination angle of the second inclined surface 44 .

The above content is described more specifically: when the first and second inclined surfaces 43, 44 are arranged at the same position in the left-right direction (the direction in which the main body 3 moves closer to and moves away from the bottom pad 1), the above-mentioned baseline is in the horizontal plane extending in the front-back direction. In other words, the base line runs parallel to the left and right inner sides of the base body in a horizontal plane. Therefore, the inclination angles of the first and second inclined surfaces 43 and 44 are inclination angles with respect to a horizontal line extending in the front-rear direction, and are inclination angles with respect to the left and right inner surfaces of the base body. In addition, at this time, the main body 3 moves closer to the bottom pad 1 in the left and right directions within the horizontal plane. On the other hand, when the first and second inclined surfaces 43 and 44 are arranged at different positions in the left-right direction, the base line is in the horizontal plane, but is inclined with respect to the front-rear direction. Therefore, the inclination angles of the first and second inclination surfaces 43 and 44 are inclination angles with respect to the horizontal line (base line) inclining to the front-rear direction. In addition, at this time, the approach movement direction of the main body member 3 also becomes the direction inclined to the front-back direction.

The following describes the installation of the main part 3 to the second movable part 13 of the bottom pad 1 with respect to the hinge device A having the above-mentioned structure. When attaching the main body 3 to the second movable member 13, the main body 3 is moved closer to the second movable member 13 (moved to the left) with the open portion of the main body 3 facing leftward. At this moment, the operating member 48 is in the initial position. When the main body 3 is moved to a predetermined position, as shown in FIG. 6 , the first engaging shaft 46 abuts against the first inclined surface 43 , and at the same time, the second engaging shaft 50 abuts against the second inclined surface 44 .

When the main body 3 is further moved to the left, the first engaging shaft 46 intends to move forward on the first inclined surface 43 , and the second engaging shaft 50 intends to move backward on the second inclined surface 44 . However, since the inclination angle of the first inclined surface 43 is larger than that of the second inclined surface 44 , the first engaging shaft 46 moves forward on the first inclined surface 43 as shown in FIG. 7 . As a result, the main body 3 moves forward, and the second engaging shaft 50 moves forward on the second inclined surface 44 . When the second engaging shaft 50 moves forward on the second inclined surface 44 , the second inclined surface 44 pushes the second engaging shaft 50 backward. However, since the force of the coil spring 49 to move the second engagement shaft 50 forward is greater than the force of the second inclined surface 44 to push the second engagement shaft 50 backward, the operating member 48 is maintained at the initial position. Here, the second engagement shaft 50 is positionally fixed in the front-rear direction with respect to the main body 3 .

When the main body 3 is further moved to the left, the first engagement shaft 46 goes over the first inclined surface 43 and the next arc surface to the left, and faces the opening of the first engagement recess 41 . When the main body 3 is further moved to the left in this state, then as shown in FIG. 8 , the second engagement shaft 50 moves rearward on the second inclined surface 44. The engaging shaft 46 is inserted into the first engaging recess 41 from the opening of the first engaging recess 41 until it abuts against the bottom surface thereof, and the first engaging shaft 46 engages with the first engaging recess 41 .

In the state where the first engagement shaft 46 is engaged with the first engagement recess 41, the first engagement shaft 46 is prevented from moving to the left by the left side of the first engagement recess 41. As a result, the front end portion of the main body 3 Movement to the left is blocked. Therefore, after the first engagement shaft 46 is engaged with the first engagement recess 41, only the rear end portion of the main body 3 is moved leftward.

When allowing the rear end of the main body 3 to move to the left, because the second inclined surface 44 is more inclined to the rear as it goes to the left, the second engagement shaft 50 is pushed backward by the second inclined surface 44, and in the second Move backward on the inclined surface 44. In addition, when the second engaging shaft 50 moves backward, the operating member 48 is forced to rotate in the direction from the initial position to the limit position (counterclockwise in FIG. 8 ) overcoming the additional rotational force of the coil spring 49 .

When allowing the rear end of the main body 3 to move further to the left, as shown in FIG. Then, when the second engagement shaft 50 faces the open portion of the second engagement recess 42, the operating member 48 is rotated in a direction (clockwise in FIG. 9 ) from the extreme position to the initial position by the coil spring 49, and the second 2. The engagement shaft 50 is moved forward and inserted into the second engagement recess 42. The second engagement shaft 50 is inserted into the second engagement recess 42 until it comes into contact with the bottom surface and engages with the second engagement recess 42 . When the second engaging shaft 50 is engaged with the second engaging recess 42 , the lateral and forward movement of the second engaging shaft 50 is prevented by the side surfaces and the bottom of the second engaging recess 42 , respectively. As a result, the rear end of the main body member 3 engages with the rear end of the second movable member 13 and cannot move in the left-right direction or forward.

In addition, since the second engagement shaft 50 is prevented from moving backward due to the additional force of the coil spring 49, when the main body 3 is pushed forward with a force greater than the additional force of the coil spring 49, the main body 3 will move toward the front. Moving forward, the first engaging shaft 46 is about to escape from the first engaging recess 41 forward. However, in this embodiment, as described above, since the support shaft 47 abuts against the stop surface 45 through the coil spring 49, the first and second engagement shafts 46, 50 and the first and second engagement recesses In the engaged state of 41 and 42, the main body 3 will not move in the forward and backward direction. Therefore, the first and second engaging shafts 46 , 50 will not come out of the first and second engaging recesses 41 , 42 due to accidents, and the main body 3 will not be separated from the second movable member 13 .

When the main part 3 is to be removed from the second movable part 13, the operating part 48 is rotated counterclockwise against the additional force of the coil spring 49, and the second engagement shaft 50 is released from the second engagement recess 42 to the rear. . Thereafter, the rear end of the main body 3 is moved to the right, and the second engagement shaft 50 is moved to the right than the second engagement recess 42, preferably to the right than the second inclined surface 44. . Next, the main body 3 is moved forward, and the first engagement shaft 46 is disengaged from the first engagement recess 41 forward. Thereafter, let the main body part 3 move to the right and move away from the second movable part 13 to the right. Accordingly, the main body 3 can be detached from the second movable body 13 .

In the hinge device A configured as described above, the main body 3 is brought closer to the second movable member 13 in a state where the first and second engaging shafts 46, 50 are in contact with the first and second inclined surfaces 43, 44, respectively. When moving (moving to the left), the second engaging shaft 50 engages with the second engaging recess 42 after the first engaging shaft 46 automatically engages with the first engaging recess 41 . Therefore, there is no need to move the door and window in the front-rear direction in order to engage the first engaging shaft 46 with the first engaging recess 41 . Therefore, the main body 3 can be easily attached to the second movable body 13 (bottom pad 1).

A second embodiment of the present invention will be described below with reference to FIGS. 10 to 15 . It should be noted that, with regard to the second embodiment, only the structures different from those of the above-mentioned first embodiment will be described, and the same structural parts as those of the above-mentioned first embodiment will be assigned the same reference numerals and will not be described again.

In the hinge device B of the second embodiment, the coupling mechanism 4 for detachably attaching the main body member 3 to the second movable member 13 is different from that of the hinge device A of the first embodiment described above.

At the front and rear ends of the second movable member 13, a first engagement shaft (first engagement portion) 51 and a second engagement shaft (second engagement portion) 52 with the longitudinal direction facing the up-down direction are respectively provided, replacing the above-mentioned The first and second engagement recesses 41 and 42 of the first embodiment. Both ends in the vertical direction of the first and second engaging shafts 51 and 52 protrude in the vertical direction from both side surfaces in the vertical direction of the second movable member 13 .

A first engagement recess 53 is formed in the main body 3 . That is, the insertion recessed part 54 is each formed in the front-end|tip part of the left side surface of the side wall part 3a of the main body 3 facing the up-down direction, and 3a. Among the front and rear side surfaces defining the insertion concave portion 54 , a first engagement concave portion 53 extending forward from the side surface is formed at an end portion on the bottom side of the front side. The first engaging recess 53 has its front end closed by the bottom surface, and its rear end is open toward the insertion recess 54 .

Both ends of the first engaging shaft 51 can be engaged with the respective first engaging recesses 53 . That is, when the main body 3 is moved leftward, the end of the first engagement shaft 51 is inserted into the insertion recess 54 . After the first engagement shaft 51 is inserted into the insertion recess 54 until it substantially touches the bottom surface, when the main body 3 is moved backward, the first engagement shaft 51 is inserted from the insertion recess 54 into the first engagement recess 53 . When the first engagement shaft 51 is inserted into the first engagement recess 53 until it is engaged with its bottom surface, the movement of the first engagement shaft 51 in the left and right directions is blocked by the left and right sides of the first engagement recess 53 , and the forward movement of the first engagement shaft 51 is blocked by the bottom surface of the first engagement recess 53 . Therefore, in a state where the first engaging shaft 51 is engaged with the first engaging recess 53 , the movement of the main body 3 relative to the second movable member 13 (bottom pad 1 ) in the left-right direction and rearward is prevented.

Among the front and rear sides of the insertion recess 54 , the front side where the first engagement recess 53 is formed serves as the first inclined surface 55 . The first inclined surface 55 extends from the leftward surface of the side wall portion 3 a to the first engagement recess 53 , and is inclined so that the rear end thereof is located on the right side relative to the front end. The rear end of the first inclined surface 55 is smoothly connected to the left side of the first engagement recess 53 via an arc surface with a small curvature radius.

The support shaft (contact portion) 56 whose longitudinal direction faces the vertical direction is fixedly arranged on the rear end portion of the main body 3 . The engaging member 57 is supported by the supporting shaft 56 so as to be rotatable in the horizontal direction. The engaging member 57 can rotate between an initial position shown in FIGS. 11 and 12 and a limit position, and the limit position is slightly in front of the position shown in FIG. 14 which is rotated counterclockwise from the initial position. The engaging member 57 is biased by a coil spring (additional force unit) 58 in a direction (clockwise in FIGS. 10 to 15 ) from the limit position to the initial position. When the main body part 3 is detached from the second movable part 13, the engaging part 57 is in the initial position by the additional rotation force of the coil spring 58.

A second engaging concave portion 59 is formed in the engaging piece 57 . The second engagement recessed portion 59 is arranged at an end portion on the left side of the support shaft 56 of the engagement member 57 at the initial position. More specifically, it is arranged at the part where the tangent direction of the circle of rotation of the engaging member 57 is approximately in the front-rear direction when it rotates around the support shaft 56, and is located on the left side (bottom pad 1 side) of the support shaft 56. part. Therefore, when the engaging member 57 rotates between the initial position and the limit position, the second engaging concave portion 59 basically moves in the front-rear direction. The second engaging recess 59 is arranged so as to extend in the front-rear direction when the engaging piece 57 is in the initial position, the front end is opened forward, and the rear end is closed by the bottom surface.

The second engagement shaft 52 can engage with the second engagement recess 59 . That is, the second engagement shaft 52 can be inserted into the second engagement recess 59 from its opening, and when inserted into the second engagement recess 59 and reaches the engagement position abutting against its bottom surface, it engages with the second engagement recess 59. combine. In the state where the second engagement shaft 52 is engaged with the second engagement recess 59, the movement of the second engagement shaft 52 in the left and right direction is stopped by the left and right sides of the second engagement recess 59, and the second engagement The rearward movement of the shaft 52 is prevented by the bottom surface of the second engaging recess 59 . As a result, the rear end portion of the main body member 3 is locked to the second movable member 13 of the bottom pad 1, and cannot move in the left-right direction and rearward. It should be pointed out that the engaging position is the same as the engaging position in the above-mentioned hinge device A, and is set at a position just before the initial position in the direction from the extreme position to the initial position. Therefore, the engaging member 57 is maintained at the engaging position by the additional force of the coil spring 58 .

A second inclined surface 60 is formed on the engaging piece 57 . The second inclined surface 60 is disposed on the left side of the second engaging concave portion 59 when the engaging member 57 is in the initial position. The second inclined surface 60 is inclined such that the front end of the engaging piece 57 is located on the right side of the rear end when the engaging member 57 is in the initial position, that is, it is inclined in a direction opposite to the first inclined surface 55 . Of course, the inclination angle of the second inclined surface 60 with respect to the base line is set to be smaller than the inclination angle of the first inclined surface 55 with respect to the base line.

A third inclined surface 61 is formed on the engaging piece 57 . The third inclined surface 61 is arranged such that its rear end is smoothly connected to the front end of the second inclined surface 60, and is inclined so that its front end is on the right side of the rear end. The inclination angle of the third inclined surface 61 is set larger than the inclination angle of the first inclined surface 55 . The front end portion (right end portion) of the third inclined surface 61 is smoothly connected to the end portion on the open side of the left side surface of the second engaging recess 59 via an arc surface with a small radius of curvature. As a result, the front end of the second inclined surface 60 is smoothly connected to the end of the second engaging recess 59 on the left side of the opening side through the third inclined surface 61 and the arcuate surface.

In the hinge device B having the above structure, when attaching the main body member 3 to the second movable member 13 of the bottom pad 1, it can be attached as follows. That is, as shown in FIG. 11, first, the first and second engagement shafts 51, 52 are pressed against the first and second inclined surfaces 55, 60, respectively. The main body 3 is moved to the left (direction toward the bottom mat 1 ) while maintaining the state. Then, since the inclination angle of the first inclined surface 55 is larger than the inclination angle of the second inclined surface 60 , the first engaging shaft 51 relatively moves backward on the first inclined surface 55 . While the main body 3 moves forward along with it, the second engaging shaft 52 moves forward on the second inclined surface 60 .

When the first engaging shaft 51 passes over the first inclined surface 55 , it faces the opening of the first engaging recess 53 . When the main body 3 is further moved leftward in this state, the first engaging shaft 51 abuts against the bottom surface of the insertion recess 54 . As a result, the movement of the front end portion of the main body member 3 to the left is prevented. So thereafter only the rear end of the main body part 3 moves to the left. When the rear end of the main body 3 moves to the left, the second engaging shaft 52 is forced to move relatively forward due to the second inclined surface 60, and the main body 3 is forced to move backward. Accordingly, the first engagement shaft 51 is inserted into the first engagement recess 53 until it abuts against the bottom surface thereof (see FIG. 12 ).

After the first engagement shaft 51 is inserted and abutted against the bottom surface of the first engagement recess 53 , when the main body 3 is further moved to the left, the second inclined surface 60 is pushed backward by the second engagement shaft 52 . As a result, the engaging member 57 is rotated from the initial position to the limit position side. When the rear end of the main body 3 is further moved to the left and the engaging member 57 is rotated from the initial position to the limit position by a given angle, as shown in FIG. 13 , the second engaging shaft 52 passes over the second inclined surface. 60 and in contact with the third inclined surface 61.

In the state where the second engaging shaft 52 is in contact with the third inclined surface 61, when the rear end of the main body 3 is further moved to the left, as shown in FIG. The surface 61 is in contact with the arcuate surface. When the second engagement shaft 52 passes over the part on the frontmost side of the arc surface, the engagement member 57 is rotated from the limit position side to the initial position due to the coil spring 58, and the second engagement shaft 52 is inserted The second engagement recess 59 (see FIG. 15 ). The second engagement shaft 52 is inserted into the second engagement recess 59 until it abuts against the bottom surface of the second engagement recess 59 (see FIG. 10 ). When the second engagement shaft 52 abuts against the bottom surface of the second engagement recess 59 , the second engagement shaft 52 becomes engaged with the second engagement recess 59 , and at the same time, the engagement member 57 stops at the engagement position. When the second engagement shaft 52 is engaged with the second engagement recess 59, the rear end portion of the main body 3 cannot move in the left-right direction and cannot move forward.

In this way, the front and rear ends of the main body 3 are respectively detachably engaged with the front and rear ends of the second movable part 13 of the bottom pad 1, whereby the main body 3 is detachably mounted on the second movable part. 13. The main body 3 can be detached from the second movable member 13 by rotating the engaging member 57 from the engaging position toward the limit position by a predetermined angle.

It should be pointed out that although in the above-mentioned second embodiment, the second engagement shaft 52 is fixedly provided at the rear end of the bottom pad 1, and the engagement member 57 is rotatably provided at the rear end of the main body 3, but The engaging member 57 may be rotatably provided at the rear end of the bottom pad 1 , and the second engaging shaft 52 may be fixedly provided at the rear end of the main body member 3 . However, even in the case of such deformation, the second engaging concave portion 59 and the second inclined surface 60 are provided on the engaging member 57 . Furthermore, the second engaging recess 59 opens in the same direction as the first engaging recess 53 .

In addition, when the engaging member 57 is provided at the rear end of the bottom pad 1 and the second engaging shaft 52 is provided at the rear end of the main body 3, the front end of the bottom pad 1 can also be formed in the same manner as the first engaging recess 41.
