2. Description of the Related Art As a conventional spring mounting structure for an opening / closing cover, for example, there are structures shown in FIGS.
FIG. 6 is an enlarged view of a main part of the spring mounting structure. 2A is a hinge bracket attached to the chassis of the box-shaped base cabinet 2, 3 is a hinge, and 4 is an opening / closing cover.
The opening / closing cover 4 covers the upper part of the base cabinet 2 and is formed so as to be openable / closable by a hinge 3.

The hinge bracket 2A is provided with support shafts 5 projecting on both sides, and the lower end portion of the hinge 3 is rotatably supported at its tip portion. A coiled hinge spring (torsion spring) 6 is attached to the support shaft 5,
One end 6a of the hinge spring 6 engages with an L-shaped hook (engagement body) 2a which is formed by cutting and raising a part of the hinge bracket 2A as shown in FIG. 7, and the other end 6b. Engages with the front edge 3a of the hinge 3 to urge the hinge 3 rearward and upward to open and close the open / close cover 4.

[0004]

However, in such a conventional spring mounting structure, in the assembling process, the hinge spring 6 is supported by the support shaft 5, and one end portion 6a of the hinge spring 6 is hinge bracket 2A. After engaging with the hook 2a of No. 2, other parts are attached. However, since the hook 2a is open upward, the one end 6a of the hinge spring 6 is removed from the hook 2a during another attachment. The metal fitting of the hinge 3 needs to be bent in order to prevent it from coming off, which causes a problem of high cost.

Therefore, the present invention has been made in view of such conventional problems, and by providing the protrusions on the hook (engaging body), it is not necessary to bend the hinge metal fittings, so that the cost can be reduced and the design can be achieved. It is an object of the present invention to provide a spring mounting structure that is easy to assemble, quick to assemble, and easy to mount a spring.

[0006]

In order to achieve the above-mentioned object, the present invention provides a bracket with an engaging body for attaching one end of a spring attached to a support shaft of a hinge portion, and the engaging body is provided with the spring. It is characterized in that it is provided with a protrusion for preventing the slip-out.

[0007]

In the present invention, since the engaging body is provided with the projection,
At the time of mounting, the end of the spring is engaged while pressing a small gap between the bracket and the protrusion of the engaging body, and after the engagement, it does not come out upward during the movement of the assembly.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show an example in which an embodiment of a spring mounting structure for an opening / closing cover according to the present invention is applied to a multifunction telephone with a facsimile, and the same configurations as those shown in FIGS. 6 and 7 are the same. Add a sign. First, the configuration will be described. 1 to 3, reference numeral 11 denotes a facsimile-equipped multifunction telephone. The facsimile-equipped multifunction telephone 11 is provided in a base cabinet 2 so as to be openable and closable, and a coiled hinge spring (torsion spring) 14 attached to a hinge 13 is used. It has an opening / closing cover 4 biased in the opening direction.

An operating portion 16 is provided on the front side of the opening / closing cover 4.
However, on the back side of the front part is a large-screen liquid crystal type display 17,
Telephone (handset) 1 on the left side of the front part (left side of Fig. 1)
A mounting portion 19 for mounting 8 is provided. Operation unit 16
Is provided with a numeric keypad 21, a cursor key 24, etc. for multifunctionally operating facsimile and telephone information. Two
Reference numeral 7 is a recording paper discharge port, 28 is a document insertion port, and 29 is a document discharge port. As shown in FIG. 2, the base cabinet 2 accommodates a receiving unit 32, a transmitting unit 33, and an information processing unit 31 that processes the operation content of the operating unit 16.

A chassis 34 is mounted on the base cabinet 2 for supporting electric components such as an information processing unit, a transmitting unit and a receiving unit, a printed wiring board, a CPU, a ROM and a RAM. As shown in FIGS. 3 and 5, a pair of support shafts 36 are fixed outward to a hinge bracket 35 attached to the side of the chassis 34, and an opening / closing cover 4 is attached to an end of the support shaft 36. A beak-shaped support engagement portion 37a at the lower end portion of a support bracket 37, which is a pair of odd-shaped hinges attached to both rear sides of the bottom plate 4a, is rotatably and disengageably provided.

A coil-shaped hinge spring 14 is arranged between the hinge bracket 35 and one of the support brackets 37, and one end of the hinge spring 14 has its end portion substantially downward at a right angle (downward in FIG. 3). It has a bent portion 14A that is bent inward, and can be engaged from above with a hook 38 that is an engaging body that is formed by cutting and raising the hinge bracket 35 and that projects outward in an L-shape. Further, a projection 39 projecting toward the hinge bracket 35 is provided at the end of the hook 38 so that the distance between the hook 38 and the hinge bracket 35 is slightly smaller than the diameter of the hinge spring 14. On the other hand, the other end is detachably provided on the front edge 37b of the support bracket 37 and urges the opening / closing cover 4 in the opening direction.

An inwardly projecting lock screw 40 is screwed near the front edge 37b of the support bracket 37, and a tip portion 40a of the lock screw 40 is a plate when the opening / closing cover rotates about the support shaft 36. The lock spring 41 is engaged with the tip ends of two bent arm portions (leaf spring portions) 41a to hold the opening / closing cover 4 in an open state.

Next, the operation will be described. When assembling the multifunction telephone 11 with a facsimile, the hinge spring 1

4 is inserted from the upper side to the lower side of the hook 38 so that one end of the hook 4 is engaged with the hook 38 of the hinge bracket 35. The hinge spring 14 hits the protrusion 39, spreads the hook 38 outward, and gives a clicking feeling of clicking, and moves into the hook 38.
The bent portion 14A is engaged with the hook 38 while protruding toward the front side of the hook 38.

Further, during assembly, even if the hinge bracket 35 tilts, the hinge spring 14 abuts on the protrusion 39 and does not come out upward, and even if the hinge spring 14 tries to shift from the support shaft 36. Since the bent portion 14A at one end is engaged with the hook 38,
It is possible to prevent the hook 38 from falling off.
Therefore, the hinge spring 14 and other parts can be quickly attached. Further, the protrusion 39 can be designed extremely simply by only changing the cut-and-raised shape of the hinge bracket 35. The chassis 34 and the hinge bracket 35 may not be separate bodies, but may be an integral structure.

[0015]

As described above, according to the present invention,
By providing the hook (engagement body) with the protrusion, the bending process of the hinge fitting is not required, the cost can be reduced, the design is easy, and the spring can be easily attached, so that the assembly can be performed easily and quickly.
