Description

[Detailed description of the invention] This invention relates to a hinge device used for the joints of mannequin dolls formed of plates, and allows a pair of mounting plates that are pivoted to each other to be fixed at almost any angle. It also ensures that this state is maintained.

A hinge device used for the joints of a mannequin made of plates requires that the angle of the pair of mounting plates can be maintained constant, for example, when an object is placed on the mannequin's hand. Requires the arm to be bent at the elbow and the hand held in a horizontal position in order to place or hang objects on it.
Therefore, conventionally, for example, as illustrated in FIG. 9, a pair of mounting plates are connected by a support shaft inserted into a pipe fixed to each of the mounting plates.
In addition, the angle of the pair of mounting plates is determined by the engagement of the chevron-shaped uneven parts formed on the joint end surfaces of the pair of pipes, but changing the angle of the mounting plates loosens the clamping of the pipes by the support shaft. This requires a considerable amount of time and effort, and fixing the angle is also unstable.

This proposal solves the above problem, in which a support plate is erected on the side of one mounting plate opposite the other mounting plate of a pair of mounting plates that are pivoted to each other, and the support plate of the other mounting plate is A support plate is erected on two sides perpendicular to the support plate to sandwich it in the same direction as the support plate, and a plurality of engagement holes in each support plate are arranged on an arc centered on the shaft attachment part of the mounting plate. The support cylinders, which are arranged one on top of the other and whose axes are aligned in the direction between the pair of support plates, are fixed to the support plate at a position where they overlap with the engagement holes, and are engaged with pins that are inserted into the support cylinders and can be inserted into the engagement holes. There is a spring between the balls with a diameter larger than the matching hole, which urges them toward the support plate, and the knob provided on the pin is inserted into the operation hole provided in the support tube, and the operation hole is inserted into the pin. It consists of a release part that is longer in the axial direction and a locking part that is shorter than the release part that extends from the end on the ball side in the circumferential direction of the pin, and when the pin is located in the knob locking part, the engagement hole The gist is that it has been made long enough to go through.

The hinge device used in the joints of the mannequin doll of this invention will be explained with reference to the embodiment shown in the drawings. 1 is a rectangular mounting plate, and each of its two opposing sides is bent approximately at right angles to the mounting plate 1. Support plates 2, 2 are formed. Reference numeral 3 denotes a rectangular mounting plate that is paired with the mounting plate 1, and has bearings 4, 4 made substantially perpendicular to the mounting plate 2 at each end of its two opposing sides. Each of the bearings 4, 4 is stacked on the inner side of the end of the support plates 2, 2 near the mounting plate 1, and the bearings 4, 4 and the support plates 2, 2 are pivotally attached to each other by a support shaft 5. . The bearing 4 can also be a pipe. 6 is a support plate provided on the side parallel to the axis of the support shaft 5 at the end of the mounting plate 3 having the bearing 4; this is bent in the same direction as the bearing 4 with respect to the mounting plate 3; It is wide enough to fit between 2 and 2. Reference numeral 7 designates engagement holes provided in the support plates 2, 2 so as to overlap each other on a circular arc centered on the axis of the support shaft 6, and a plurality of engagement holes 7 are formed at intervals from each other.

Reference numeral 8 denotes a support cylinder fixed to the support plate 6, whose axis is parallel to that of the support shaft 5, and which is connected to the engagement hole 7.
It is placed in a position that overlaps with Reference numeral 9 denotes a ball made of iron or the like inserted into one end of the support tube 8, and is sized so that a portion of the ball fits inside the engagement hole 7 without passing through it. Reference numeral 10 denotes a pin made of iron or the like that is slidably inserted into the support tube 8, and has a diameter such that at least its end can be inserted into the engagement hole 7. 11 is a spring inserted into the support cylinder 8 at the ball 9 and pin 10 in order to bias the ball 9 and pin 10 toward the support plates 2 and 2, respectively; 12 is a spring inserted into the support cylinder 8 at a position overlapping with the pin 10; This is an operation hole provided, which is formed by a release part 13 made longer in the axial direction of the support tube 8, an end of the ball 9, and a release part 9 connected to the end of the ball 9 in the radial direction of the support tube 8. It also consists of a short locking part 14. 15 has an end fixed to the pin 10,
The knob is protruded in the radial direction, and is exposed to the outside of the support tube 8 through the operation hole 12. When the knob 15 is in the release part 13 of the operation hole 12, the pin 10 is inserted into the engagement hole 7, and when the knob is in the locking part 14, the pin 10 is removed from the engagement hole 7. The length of the pin 10 is set. 16 is the support plate 2 of the mounting plates 1 and 3, and the bearing 4
The mounting plates 1 and 3 are fixed to a plate mannequin or the like using machine screws fixed and erected on the side surfaces.

Fig. 6 shows that the mounting plates 1 and 3 are positioned inside the support plates 2 and 2 in order to close the gap created between the support plates 2 and 3 when the angle of the mounting plates 1 and 3 becomes smaller than 180 degrees. Cover 17 on the mounting plate 3 side in parallel with
In this example, you can improve the appearance by doing this. 18 is a mannequin made of a board, and 19 is a hand of the mannequin.

As shown in FIG. 2, the hinge device used for the joints of this mannequin is such that the angles of the mounting plates 1 and 3 can be arbitrarily set by fixing the mounting plates 1 and 3 to each other. When fixing a plate to the mounting plates 1 and 3, it is best to stack the plate on the side of the mounting plates 1 and 3 that has the support plate 2 or the bearing 4, and to place the side without the support plate 2 on the front side. Suitable from, but can be any.

When changing the angle of the mounting plates 1 and 3, the knob 15 is positioned at the locking portion 14 of the operating hole 12, as shown in FIG. Then, the pin 10 comes out of the engagement hole 7 of the support plate 2 and maintains that state.
The mounting plates 1 and 3 are freely rotatable. In addition, ball 9
is engaged with the engagement hole 7 of the other support plate 2, and since it is biased by a spring 11, it can be easily moved by compressing the spring 11. and,
Since the ball 9 engages with the engagement hole 7 in sequence and moves, in the state where the ball 9 is engaged with the engagement hole 7,
When the rotation of the mounting plates 1 and 3 is stopped, the pin 10 is aligned with the engagement hole 7. After determining the angles of the mounting plates 1 and 3, move the knob 15 to the release part 13 of the operation hole 12 as shown in FIG. 4, and the pin 10 will be inserted into the engagement hole 7 by the force of the spring 11. , the support plate 2 and the support plate 6 are connected to each other via the support cylinder 8 and the pin 10, and the mounting plates 1 and 3 become immovable. The pin 10 inserted into the engagement hole 7 pushes the spring 1 toward the support plate 2.
1, the pin 11 does not come out of the engagement hole 7 unnecessarily, and the mounting plates 1 and 3 are set at a required angle and this state is maintained reliably.

As mentioned above, the hinge device used for the joints of this mannequin makes the mounting plates 1 and 3 unrotatable by inserting the pin 10 into the engagement hole 7 provided in the support plate 2. This state can be maintained reliably, and if used for each joint of a mannequin made of plates as shown in the drawings, it is possible to maintain any desired shape. For example, if you hold your hand almost horizontally as shown in Figure 8, you can place or hang a product on it, and the weight of the product will cause your horizontal hand to descend and drop the product. You can safely display your products without any hassle. When changing the angle of the mounting plates 1 and 3, the ball 9 repeatedly engages and disengages from the engagement hole 7, so the mounting plates 1 and 3 are moved with the ball 9 engaged with the engagement hole 7. 3 is stopped, the pin 10 is aligned with the engagement hole 7, and the angle of the mounting plates 1 and 3 can be easily set.
