る。 The present invention was devised to deal with such a problem, and in order to transmit the biasing force of the coil spring in the opening direction to the top cover, a cam-shaped rotating body pivoted on the main body of the device is provided with a horizontal surface at a 90 degree opening position. The top cover is shaped so that its horizontal surface receives the biasing force from the coil spring, and prevents the top cover from opening at an angle of more than 90 degrees. The present invention will be explained below based on drawings showing an example of implementation. In the figure, reference numeral 1 indicates the device body attached to the upper end of the rear wall of the casing 2 with screws, etc., and 3 indicates a horizontal shaft 4 attached to the upper end of the device main body 1.
The other lid support plate 5 is fixed to the lid support plate 3 by spot welding. The device main body 1 has a central plate portion 6
and side plate parts 7, 7 which are bent and connected on both sides of the plate part 6; Plate parts 8, 8 having screw insertion holes 8a, 8a, and receiving pieces 9, 9 bent and connected to the lower ends of the side plate parts 7, 7.
The upper end of the side plate parts 7, 7 is the central plate part 6.
Insertion holes 10a, 10a for the shaft 4 are formed in the protrusions 10, 10 that protrude upward from the shaft 4.
Further, the one lid support plate 3 has plate parts 11, 11 located inside the protruding parts 10, 10 bent and continuous on both sides of the lower end, and these plate parts 11, 11 also have the shaft 4.
Through holes 11a, 11a are formed. Further, the other lid support plate 5 is bent so that its upper end 5a has a gap between it and the upper end 3a of the one lid support plate 3 to the extent that the upper lid 12 can be held via the anti-slip plate 13. The lower end 5b is spot welded to the lower end 3b of one lid support plate 3. By the way, between the plate parts 11 and 11 of the one lid support plate 3, there is a cam-shaped rotating body made of synthetic resin having an insertion hole 14a that communicates with the insertion holes 10a, 10a, 11a, 11a and through which the shaft 4 is inserted. 14 are located. This cam-shaped rotating body 14 has the plate portions 11, 11 at both ends.
The front end has protrusions 15, 15 that come into contact with the front end of the through hole 14a, and the diameter of the front end gradually decreases toward the bottom surface around the center of the insertion hole 14a.In other words, the diameter gradually decreases from the bottom surface toward the top. It has an arc-shaped cam surface 16 with a large diameter, and has a horizontal surface 17 connected to this cam surface 16 on the lower surface, and furthermore, the cam-shaped rotating body 1
The rear end surface of 4 is formed so as to be able to come into contact with the lower end 5b of the other lid support plate 5, and a long groove 18 is formed in the rear end surface in the horizontal direction, so that the rear end surface of the other lid support plate 5 A stepped portion 19 is formed at the upper end near the rear end surface to engage with a protrusion 5c formed on the lower end 5b, and to engage with the lower portion of the upper end 5a of the other lid support plate 5. By the way, the device main body 1
Inside, there is a bottom plate 21 with screw holes 20 that rests on the receiving pieces 9, 9 from the lower end below the lid support plates 3, 5 and the cam-shaped rotating body 14 attached thereto, and a lower side located on this bottom plate 21. a spring receiving plate 22; a spring holder 24 having two spring insertion holes 23, 23 whose lower end engages with the spring receiving plate 22 and passes through them in the vertical direction; an upper end protruding into the spring insertion holes 23, 23; Two coil springs 25 are inserted so that
25, an upper spring receiving plate 26 is provided between the upper ends of the two coil springs 25, 25 and the cam-shaped rotating body 14, and the screw hole 20 of the bottom plate 21 is provided with An adjustment screw 27 is screwed together to press the spring receiving plate 22 upward to adjust the spring force.
従つて前記他方の蓋支持板５は下端５ｂが一方

ーシング２の上端に開閉可能に設けられる。 Therefore, the lower end 5b of the other lid support plate 5 is spot welded to the lower end 3b of the one lid support plate 3, and the cam-shaped rotary body 14 is spot welded to the lower end 3b of the other lid support plate 3, as shown in FIG.
By being pushed toward the lower end 3b side of one lid support plate 3 by the rear end surface, and by engaging the stepped portion 19 with the lower part of the upper end 5a of the other lid support plate 5, the side of one lid support plate 3 is pushed. , and the protrusion 5c further engages with the long groove 18, so that one lid support plate 3
This is something that will definitely be supported. The base end of the upper lid 12 is inserted between the lid support plates 3 and 5 via the anti-slip plate 13 and fixed with screws 28, and as shown in FIGS. 1 and 5, the upper lid 12 is attached to the casing 2. It is installed at the upper end of the holder so that it can be opened and closed.

は90度開いた状態で止まり、それ以上の開動は防
止される。 Next, the operation of opening and closing the top lid by the lid opening and closing device having the above structure will be explained. The larger the opening angle of the upper lid 12 is up to 90 degrees with respect to the upper end surface of the casing 2, the smaller the load applied to the coil springs 25, 25 via the lid support plates 3, 5 and the cam-shaped rotating body 14. Conversely, the smaller the opening angle, the more the coil spring 2
The load applied to the coil springs 5 and 25 increases, and the weight of the top cover 12 cannot be supported by the coil springs 25 and 25. Therefore, the cam surface 16 is formed on the cam-shaped rotating body 14 to resist the rotation of the top lid 12 so that the top lid 12 does not close suddenly when it is closed. Furthermore, when the upper lid 12 is opened, if a force is applied to the upper lid 12 by hand in the opening direction, the upper lid 12 automatically tries to open due to the repulsive force of the coil springs 25, and the cam-shaped rotating body 1
4 is formed with a horizontal surface 17, the upper spring receiving plate 26 comes into surface contact with this portion, and the upper lid 12
will remain open at 90 degrees, and further opening movement will be prevented.

度以上開動することがない。 The lid opening/closing device of the present invention can be implemented as described above, and is designed to stop the top lid at a maximum opening angle of 90 degrees.
A horizontal surface is formed at the 90-degree opening position, and this horizontal surface receives the biasing force from the coil spring, so when the top cover is opened by the biasing force of the coil spring, it will surely stop at a 90-degree angle. 90 due to the momentum of the top cover due to the spring biasing force.
It will not open or move more than once.
