Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge that allows a cell to be opened from a closed state in which the inner surface of the door is butted against the end surface of a mounting frame such as a column. More specifically, the present invention relates to a door which can be opened even if the door is relatively thick, by pulling the door out to the diagonal side of the mounting frame when opening the door without hitting the mounting frame.

In the conventional hinge of this type, when opening the door a from the closed state shown in FIG. 1 to the unfolded state shown in FIG. In order to prevent door a from colliding with the mounting frame, a pair of mounting members c and d, which are fixed to door a and the mounting frame, respectively, are placed approximately parallel to each other. It is connected by two links e and f that are pivoted so that the

f interfere with each other and the door cannot be opened at a wide angle, and in order to open the door at an even wider angle, link e
, it is necessary to take measures such as making the thickness of the f plate extremely thin or bending it with a large curvature, and it is therefore difficult to manufacture such a product with sufficient strength.

Furthermore, two links e and f are attached to mounting members c, respectively.

In particular, the tip of the mounting member d on the side that is fixed to the mounting frame, that is, the part where the links e and f of the mounting member d are pivoted, must protrude diagonally to the side. There are also structural drawbacks such as the need to move, and therefore, in the open state as shown in FIG. 2, this protruding portion becomes a hindrance to loading and unloading baggage.

The present invention was made to solve these problems with conventional hinges, and by connecting a pair of mounting members with a special means, a single link can be used to prevent the door from sliding out when the door is opened. to ensure that it can be carried out smoothly,
This provides a hinge that is fully satisfactory in terms of opening angle, strength, etc.

This configuration will be explained below based on the illustrated embodiment. First, in FIGS. 3 to 5, reference numeral 1 denotes a mounting member fixed to the side end of the door A, which has an opening on the top surface as shown in FIG. 6. It is located on the upper surface of a box-shaped socket part 4 which has a cavity 2 and has an opening 3 on the front side of the cavity 2, and is composed of a flange part 5 extending from approximately a half edge on the rear side. and the above opening 3
Pivot supports 7, 7 having shaft holes 6, 6, respectively, are provided on the inner surface of the side socket part 4, facing each other. A fixing member 9 having an arc-shaped circular circumferential surface 8 is provided in a protruding manner.

On the other hand, reference numeral 10 denotes a mounting member that is attached to the sides of a mounting frame B made of a wall plate, pillar, etc. through a seat plate 11, and is made by bending both sides of a long plate body approximately 90 degrees in the same direction. It is formed so that its cross section is approximately gate-shaped, and its back plate part 12 has a long hole 14 having a screw insertion hole 13, and its side plate part 1
Shaft holes 16, 16 are bored in the distal end portions of the shafts 5, 15, facing each other.

The seat plate 11 to which the mounting member 10 is to be attached to the mounting frame B is provided with stepped seats 16', 16' in the longitudinal direction of the side surface to which the side plate portion 1515 of the mounting member 10 engages, and a seat plate 11 in the center of the upper surface. A screw hole 17 is drilled in the portion, and screw insertion holes 18, 18 are drilled near both ends of the screw hole 17 across the lower surface.

Furthermore, 19 is a link that connects the above-mentioned numbered members 1 and 10 to each other, and this is a link that connects the opposing side plates 20 and 20, which are approximately dogleg-shaped.
, 20 are connected by a back plate 21, and shaft holes 22, 22, 23, 23, and 24, 24 are formed facing each other near both ends of the side plates 20, 20 and approximately in the center, respectively.

Next, 25 and 26 are gears serving as fixed transmission wheels, one of which is a cylindrical spur gear with a shaft hole 27 bored on its central axis, and the other gear 26 is approximately a quarter-inch gear. No. 1
It consists of a plate-shaped partial gear in which teeth are formed only in the same root degree, and a boss 29 having a shaft hole 28 on the central axis is provided in the center part.

Also, 30 is a gear serving as a planetary transmission wheel, which is the gear 25 mentioned above.
It consists of a cylindrical spur gear having a shaft hole 31 similarly to the above.

In this case, each gear 25, 26, 31 is
Both have the same module and the same tooth profile.

Next, to explain the compositional state of each of these constituent members, first, the gear 30 is sandwiched between the side plates 20.20 of the link 19, and its shaft hole 31 is inserted into the shaft hole 20 of the same side plate 20.20.
．． 24 and these shaft holes 24.24 and 31
A shaft pin 32 is inserted into the link 19 and its both ends are caulked, whereby the gear 30 is rotatably supported in the midsection of the link 19.

Next, with the gear 25 meshed with this gear 30, the gear 25 is sandwiched between the side plates 20, 20, and its shaft hole 27 is positioned in the shaft hole 22.22 of the same side plate 20.20. and fit the shaft pin 33 into these shaft holes 22, 22 and 27.

Further, both ends of the shaft pin 33 are fitted into the shaft holes 6, 6 of one of the mounting members 1 and caulked, so that one end of the link 19 can be rotatably pivoted between the shaft supports 7, 7 of the mounting member 1. At this time, the gear 25 is fixed so that some of its teeth press against or engage the circular circumferential surface 8 of the fixing member 9 so that it does not rotate.

On the other hand, the gear 26 is sandwiched between the side plates 20 and 20 while being meshed with the gear 30, and its shaft hole 28 is aligned with the shaft hole 23° 23 of the same side plates 20 and 20, The shaft pin 34 is inserted into these shaft holes 23, 23 and 28.

Furthermore, both ends of the shaft pin 34 are fitted into the shaft holes 16, 16 of the other mounting member 10 and caulked, thereby rotatably pivoting the other end of the link 19 to the tip of the mounting member 10. At the same time, the gear 26 is fixed to the inner surface of the back plate portion 12 of the mounting member 10 by means such as welding.

Then, the two numbered members 1 and 10 connected in this way are attached to the door A.
and mounting frame B, fit the socket part 4 of one mounting member 1 into the fitting recess provided in the edge side of door A, and screw holes 35, 35, 35 of the flange part 5.
The mounting member 1 is fixed to the door A by screwing the screws 36, 36, 36 inserted into the screw holes 18, 35 into the door A, and screws 37. 37, the seat plate 11 is fixed to the edge side surface, and this seat plate 11 is

1, screw and tighten the screw 38 into the screw hole 17 of the mounting member 1.
0 to the mounting frame B.

Therefore, in the hinge of the present invention having the above-mentioned configuration, first, in the closed state as shown in FIG.
and the link 19 is located in the cavity 2 of the other mounting member 1.
and the mounting members 1 and 10, that is, the door A and the mounting frame B, are in a state in which they are perpendicular to each other. From this state, the door A is operated in the direction of opening as shown in Fig. 4. As time progresses, the link 19 is rotated about the shaft pin 34 in the direction of the hour hand in the figure.

At this time, the gear 30, which is a planetary transmission wheel pivotally connected to the link 19, is meshed with the gear 26, which is a fixed transmission wheel, which is fixed to the shaft pin 34, which is a fixed shaft.
It performs planetary gear movement with the sun gear as a sun gear, that is, it rotates around the shaft pin 33, which is its own rotational axis, in the direction of the hour hand in the figure, while revolving around the same gear 26 in the direction of the hour hand in the figure.

Furthermore, since this gear 30 also meshes with the gear 25, which is a fixed transmission wheel, which is fixed to the shaft pin 33, which is a fixed shaft, it also relatively performs planetary gear movement using the gear 25 as a sun gear.

In other words, when the shaft pin 33 is a fixed shaft, the link 19 rotates about the coaxial pin 33 relative to the gear 25, that is, the mounting member 1 to which it is fixed, in the direction of the hour hand in the figure. The gear 30 pivotally mounted thereon revolves around the gear 25 in the same direction.

Therefore, the attachment member 1 is a link 1 that is rotated about the shaft pin 34 in the direction of the hour hand in the figure, that is, in the direction of the arrow in FIG.
9, the door A is relatively rotated in the counterclockwise direction in the figure around the shaft pin 33, and as a result, when opening the door A, the door A is extended diagonally to the side of the mounting frame B as shown by arrow A. .

Furthermore, by meshing these gears, door A can be attached to mounting frame B.
As it is extended to the side and further rotated in the unfolding direction, the agency A will be unfolded without contacting the mounting frame B, and will finally be in the unfolded state as shown in FIG.

At this time, since the mounting members 1 and 10 are connected by a single link 19, the door A has changed from the state shown in FIG.
' (approximately 105° in the illustrated case).

Next, in the above embodiment, the gear 30, which is a planetary transmission wheel, is composed of a single gear, but it can also be composed of gears having different numbers of teeth, for example, 02.

That is, in the embodiment shown in FIG. 7, the gear 30 is composed of two gears 30a30b having different numbers of teeth, both of which are pivotally connected to a shaft pin 32 and fixed to each other, and one gear 30a is connected to the gear 25. In addition, the other gear 30b is connected to the gear 26.
Of course, in this case gear 2
Gears 5 and 30a and gears 26 and 30b are gears of the same module, respectively.

However, in the embodiment of FIG. 7, gears 30a and 30b
Due to the difference in the number of teeth, a larger reduction ratio can be obtained than in the previous embodiment.

Furthermore, not only one gear 30 but also an odd number of three or more gears can be used.

That is, as in the embodiment shown in FIG. 8, gears 30, 30', 30'' of the same module, which are planetary transmission wheels, are pivotally connected to the link 19 by shaft pins 32, 32', 32'', respectively. Adjacent gears 30, 30', and 30'' are meshed with each other, and the distal end thereof, for example, in the illustrated case, gears 30 and 30'' are fixed transmission wheels such as gears 25 and 30, respectively.
It can also be constructed by meshing with link 1.
9 is made long and is used when it is desired to increase the amount of extension of the door A when the door A is opened.

Further, in each of the above embodiments, gears are used as the fixed transmission wheels and the planetary transmission wheels, but as shown in FIG. , 30 may be used. Particularly in this case, in order to improve the transmission efficiency between the friction wheels, a grooved friction wheel is provided with several grooves that engage with each other in the circumferential direction of the contacting surfaces as shown in the figure. It is preferable to use

As explained above, the present invention provides a fixed power transmission wheel 2 attached to a pair of mounting members 1 and 10 fixed to a door A and a mounting frame B of the door A, respectively.
5 and 26, respectively, and whose both ends are pivotally connected to the axes of the respective fixed transmission wheels 25 and 26, the two numbered members 1 and 10 are connected to each other, and the link 1
9, by the rotation of the link 19 about the axis, the planetary transmission wheel 30 is rotated in conjunction with the fixed transmission wheels 25 and 26, and rotates around the fixed transmission wheels 25 and 26. Since it is freely supported on the shaft, it is possible to extend the door A when the door A is opened using only a single link 19, instead of connecting the mounting member 1.10 using two links as in the conventional case. (see center mark A in Figure 4). Therefore, it is not only possible to open the door A without hitting the mounting frame B, but also to prevent the two links from interfering with each other and opening the door. Since there is no obstacle to the opening of door A, door A can be opened at an extremely wide angle, and in order to open at a wide angle, it is necessary to make the link 19 thin or curve it with a large curvature. Since the link 19 can be made of a certain width and thickness, it is possible to provide a hinge that is sufficiently strong in terms of strength.

Furthermore, since a single link 19 only needs to be pivotally connected to the mounting members 1 and 10, one pivot point is sufficient for each, and therefore, it is not necessary to protrude the tip of one of the mounting members 10. Therefore, the hinge does not become an obstacle to loading and unloading luggage.
