Description

[Detailed explanation of the invention] 〓Field of industrial use〓 This invention relates to the improvement of hinges.
This invention relates to an improvement in a hinge that can hold the lid of a case open at a desired angle.

〓Conventional technology〓 Conventionally, as shown in Fig. 3, the hinge of an attachment case, etc. has one side fixing piece 32 fixed to the main body 31 side and the other side fixing piece 34 fixed to the lid 33 side, which are adjacent to each other. A device in which the sides are pivotally connected by a common shaft 35 is used.

However, with this conventional hinge, the lid 33 cannot be held open at a constant angle as shown in FIG. Therefore, when using this type of hinge, the side wall 55 of the main body 31 and the lid 3
arm 3 with one end pivotally connected to the side wall 36 of arm 3;
7 and 38, and a connecting fitting 40 is used in combination, which pivots the other ends of both arms 37, 38 to each other around a shaft 39. A mechanism in which the shaft 39 is provided with a mechanism capable of locking the angle formed by the two shafts 38 at fixed angle intervals has also been put into practical use.

=Problems to be solved by the invention- However, in the conventional hinge described above, the connecting metal fitting 40 must be separately provided, which not only requires a lot of effort, but also the connecting metal fitting 40 is not included in the attachment case. It is known that the connecting fitting 40 is located inside the main body 31 and occupies a predetermined space, reducing the storage volume.Furthermore, it is known that it has disadvantages such as the possibility that stored items may get caught on the connecting fitting 40 and be damaged. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and aims to provide a hinge that is easy to install and does not have any obstructive parts protruding into the main body.

〓Means for solving the problem〓 In line with the above-mentioned purpose, the structure of the present invention, which is based on the scope of the above-mentioned utility model registration claim, is to solve the above-mentioned problem. A vertical hole 4 having a screw thread opening 3 is disposed at the upper end of the opening 2, and in this vertical hole 4, a screw foot 6 is inserted through the screw thread opening 3, and a screw 5 is inserted, and the screw 5 is urged downward. The other side fixing piece 8 is provided with a horizontal shaft housing hollow part 9.
A horizontal shaft 10 is rotatably housed therein, and the screw 5
Connect the tip of the screw foot 6 to the bottom surface 11 of the other side fixing piece 8.
The rotation of the other side fixing piece 8 with respect to the one side fixing piece 1 is achieved by inserting the groove 13 arranged from the side to the lower part of the one side 12 and communicating with the shaft housing hollow part 9 and screwing it onto the horizontal shaft 10 . This is a technical measure that allows the angle to be maintained at a desired angle.

〓Operation〓 Therefore, the hinge of the present invention fixes the fixing piece 1 on one side and the fixing piece 8 on the other side of the main body 31 to the lid 33 so that when the lid 33 is closed, it will be in the state shown by the solid line in FIG. From this state, when the lid 33 is rotated in the direction of arrow P to open it, the other side fixing piece 8 is tilted as shown by the chain line in the figure.

At this time, since the angle between the bottom surface 11 and one side surface 12 of the other side fixing piece 8 is at the top surface 15 of the one side fixing piece 1, the horizontal shaft 10 rises against the biasing force of the spring 7. In other words, the biasing force of the spring 7 is such that when the inclination angle of the other side fixing piece 8 is at the position shown by the chain line in the figure, the ridge line between the bottom surface 11 and one side surface 12 of the other side fixing piece 8 is When it is perpendicular to the center line of the screw 5, the other side fixing piece 8
acts to maintain the angle of inclination. When the inclination angle of the other side fixing piece 8 is in the upright direction compared to the state shown by the chain line in the figure, the biasing force of the spring 7 causes the other side fixing piece 8 to become more upright, that is, to close the lid 33. Conversely, when the other side fixing piece 8 is further tilted in the direction of arrow P from the chain line state in the figure, the biasing force of the spring 7 acts in the direction to open the lid 33.

However, in reality, the corner of the bottom surface 11 and one side surface 12 is
Frictional resistance is applied to the top, and the other side fixed piece 8 maintains the inclination angle within a predetermined inclination range centered on the inclination angle indicated by the chain line in the figure.

Therefore, when the lid 33 starts to open or finishes closing, the lid 33 is biased in the closing direction, and the lid 3
3 is opened more than a certain level, the lid 33 can be held at that open angle, and when the lid 33 is further opened, the lid 33 can be held until the one side 12 of the other side fixing piece 8 overlaps the upper surface 15, that is, the lid 33 can be held at the opened angle. 33 in the direction of opening 90 degrees.

〓Example〓 Next, an example of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, numeral 1 indicates one side fixing piece that is fixed to the main body 31 side such as an attachment case, and 8 is the other side fixing piece that is fixed to the lid 33 side. The one side fixing piece 1 and the other side fixing piece 8 have a screw hole 1 for a fixing screw 16 on the back side.
The fixing screw 16 has screws 8 and 18 and passes through the seat plates 17 and 17 arranged inside the main body 31 and the lid 33.
However, this fixing method is not limited to the illustrated example, and may be changed to various conventionally known fixing methods. Also, one side fixing piece 1 is placed on the lid 33 side, and the other side fixing piece 8 is placed on the main body 31 side.
Of course, there is no problem even if it is fixed to the side.

The one side fixing piece 1 is provided with a vertical hole 4 having an opening 2 on the lower surface 14 and a screw hole 3 on the upper surface 15,
This vertical hole 4 accommodates a screw 5 that causes the screw foot 6 to extend through the screw foot opening 3, and a spring 7 that biases the screw 5 downward. The screw 5 is inserted into the vertical hole 4 with the tip of the screw foot 6 extending through the screw foot opening 3 so as to be movable up and down. It is placed between.

The other fixed piece 8 is provided with a horizontal shaft housing hollow part 9, and a horizontal shaft 10 is rotatably housed in this shaft housing hollow part 9. The shaft housing hollow part 9 is formed horizontally from one side wall of the other side fixing piece 8, as shown by the chain line in FIG. It is easy to manufacture by inserting it into the

Furthermore, the tip of the threaded foot part 6 of the screw 5 is inserted into the groove 13 that extends from the bottom surface 11 of the other side fixing piece 8 to the lower part of the one side surface 12 and communicates with the shaft storage hollow part 9, and is inserted into the groove 13 that extends from the bottom surface 11 of the other side fixing piece 8 to the lower part of the one side surface 12 and communicates with the shaft storage hollow part 9. It is screwed onto the shaft 10. When screwing the screw 5 and the horizontal shaft 10, it is necessary to provide a screw hole 10a in the horizontal shaft 10, but if the depth of the screw hole 10a is sufficiently deep, the screw 5 can be moved forward and backward. This allows the strength of the urging force of the spring 7 to be adjusted within a certain range.

Although the present invention has been described with reference to an embodiment in which the hinge is used in an attache case, the hinge of the present invention can be used in any hinge connecting portions of other cases such as opening/closing lids and doors.

Effects of the invention Since the invention is as described above, by fixing the one-side fixing piece 1 and the other-side fixing piece 8 to the main body 31 and lid 33 of the attachment case, both can achieve the above-mentioned effect. As explained in section 1, firstly, the hinge connection is possible, and secondly, the rotation angle of the other side fixing piece 8 (lid 33) with respect to the one side fixing piece 1 (main body 31) is shown by the chain line in Fig. 2. It is possible to maintain the desired angle within a certain range around 45 degrees as indicated by .Thirdly, the biasing force of the spring 7 prevents rotation at the rotation start end of the other side fixing piece 8 (lid 33). It acts in the direction of closing the lid 33, and at the end of rotation, it acts to encourage rotation and open the lid 33, so that the lid 33 can be held open at a desired angle and the opening and closing can be ensured. It is possible to provide a hinge that is made.

In addition, the present invention requires only fixing the one-side fixing piece 1 and the other-side fixing piece 8 in place and does not require the conventional connecting fittings 40, so installation is easy and it can be used in cases, etc. It is possible to provide a hinge that does not have a protruding part that becomes a hindrance on the inside of the case, allows efficient use of the storage space of the case, and eliminates the fear of damaging the stored items.
