Description

Hinge apparatus for cover "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cover hinge apparatus, and more particularly, to a cover hinge apparatus for opening and closing a predetermined space by rotating a cover around a hinge axis.

The cover has various sizes and shapes by opening and closing a predetermined space with respect to the outside. The cover in the present specification is formed by injection molding by opening and closing a space in which electric component parts are seated. The size of the cover in the present specification is such that the operator can open and close the cover with one hand and detach it.

Such a cover is assembled by inserting a shaft opening groove formed in a cover on a hinge shaft provided on a main body side where a predetermined space is formed, and is opened and closed. However, the degree of opening of the shaft opening groove determines how easily the hinge shaft is inserted into and separated from the shaft opening groove. Which means that the hinge shaft can be separated as easily as it is easily inserted into the shaft opening groove. Therefore, it is a problem of designers to determine to what extent the shaft opening groove is to be opened and to prevent the cover from being easily separated from the space-formed main body.

These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; may be "connected," "coupled," or "connected. &Quot;

According to the drawings, a space 12 is formed at one side of the main body 10. In the drawing of the present embodiment, only a part of the structure of the main body 10 is shown with respect to the space 12. [ Actually, the space 12 is provided with other components, but it is not shown here for the sake of convenience.

On one side of the main body 10, there is a hooking jaw 14. The hooking jaw 14 is a portion to which the engaging lever 37 of the cover 26 is hooked, which will be described below. The locking lever 37 is hooked on the hooking jaw 14 so that the cover 26 can keep the space 12 covered.

A pair of shaft supporting fences 16 are provided on the opposite side of the main body 10 with the hooking jaws 14 therebetween. The shaft supporting fences 16 are formed so as to protrude from the main body 10 so as to face each other. A hinge shaft (18) is integrally formed to connect the upper ends of the shaft supporting fences (16) to each other. Of course, the hinge shaft 18 does not necessarily have to be integral with the shaft supporting fence 16. The hinge shaft 18 may be separately formed and installed in the shaft supporting fence 16. [

The hinge shaft 18 is the center of rotation of the cover 26, which will be described below. The hinge shaft 18 has a generally cylindrical shape and has a curved surface. However, a notch 20 is formed on the surface of the hinge shaft 18. The notch 20 is formed by removing a part of the curved surface of the hinge shaft 18 in a plane. The notches 20 are formed symmetrically with respect to the imaginary center axis of the hinge shaft 18. [ Therefore, the distance between the cutouts 20 paired with each other is represented by D ', as can be seen from Fig. In the present embodiment, the notches 20 are two pairs. However, the number of the cutouts 20 may be one or more.

The portion of the surface of the hinge shaft 18 which is not the cutout 20 is a curved surface as the garden portion 22. [ The diameter of the hinge shaft 18 in the garden part 22 becomes d as shown in Fig.

A cover support plate 24 is disposed on one side of the main body 10 adjacent to the hinge shaft 18. The cover supporting plate 24 protrudes from one side of the main body 10 like the shaft supporting fence 16 in this embodiment. However, the cover supporting plate 24 may be extended from one side of the shaft supporting fence 16. [ The cover support plate 24 is formed such that the longitudinal direction of the hinge shaft 18 is a width direction away from the hinge shaft 18 by a predetermined distance. The cover support plate 24 serves to support one side of the cover 26 to be described below to prevent the cover 26 from being arbitrarily separated from the main body 10. [ The cover support plate (24) is in the shape of a plate capable of being elastically deformed.

A cover (26) is used to open and close the space (12). A cover body (28) forms a skeleton of the cover (26). The configuration of the cover main body 28 may be any as long as it can open and close the space 12 of the main body 10. [

At one end of the cover main body 28, there is a hinge connection end 30. The hinge connection end 30 is a portion that is rotatably mounted on the hinge shaft 18. The hinge connecting end 30 has an axial hole forming portion 32 and a shaft hole 33 in which the hinge shaft 18 is seated is formed by the axial hole forming portion 32. The shaft hole 33 is a space in which the hinge shaft 18 can be seated and contacts a part of the hinge shaft 18 so that the cover 26 can be relatively rotated with respect to the hinge shaft 18. [ A portion of the shaft hole 33 which is in close contact with the surface of the hinge shaft 18 is referred to as a shaft guide portion 34. The shaft guide portion 34 is provided at least at both ends of the shaft hole 33 and the shaft guide portion 34 is also provided between the pair of shaft hole forming portions 32 at the center portion of the shaft hole 33. When the shaft guide portions 34 are cut in a cross section, the line on the inner surface thereof is at least a half circle.

The shaft-shaped portion 32 is formed by protruding a pair of opposed hinges 30 at a predetermined interval between the ends of the shaft-shaped portion 32. The gap becomes the shaft inlet 36, and the hinge shaft 18 becomes an inlet for entering the shaft hole 33. The width D of the shaft inlet 36 is equal to or greater than the distance D 'between the notches 20. Of course, the width D of the shaft inlet 36 is smaller than the length d of the abdomen portion 22 of the hinge shaft 18.

In this embodiment, there are two pairs of the shaft-shaped portions 32. However, at least one pair of the shaft-shaped portions 32 is required. Of course, it is more preferable that at least two pairs of the axial cavity forming portions 32 are present. This is because the rotation operation of the cover 26 can occur stably.

On the opposite side of the cover body 28 with the hinge connection end 30 there is a locking lever 37 which is hooked on the hook 14 of the main body 10. The locking lever 37 is resiliently deformable, and is elastically deformed by the hooking jaw 14 and is restored. The lock lever 37 is elastically deformed to release the lock and the cover 26 is rotated to separate the lock lever 37 when the lock lever 37 is detached from the latch jaw 14.

Hereinafter, how the cover hinge apparatus according to the present invention having the above-described structure is assembled and used will be described in detail.

In the present invention, the cover 26 serves to open and close the space 12 formed in the main body 10, and protects the articles and components stored in the space 12. [ The cover 26 is mounted to the main body 10 by the hinge shaft 18 being seated in the shaft hole 33 formed in the hinge connection end 30 of the cover 26.

The hinge shaft 18 has a rod shape and serves as a rotation center of the cover 26. The hinge shaft 18 is guided on the inner surface of the shaft hole 33, that is, on the inner surface of the shaft guide portion 34 and the shaft- Thereby causing the cover 26 to rotate relative to the hinge shaft 18. To this end, the hinge shaft 18 of the main body 10 is seated on the shaft hole 33 of the cover 26. FIG.

8, the cutout portion 20 of the hinge shaft 18 is engaged with the shaft hole 18 of the hinge connection end 30 so that the hinge shaft 18 and the hinge connection end 30 are engaged with each other. Facing each other with the tip of the male part 32 facing each other. At this time, the cover support plate 24 should be elastically deformed so as not to interfere with the cover body 28 as shown in FIG. That is, the operator can elastically deform the cover support plate 24 to position the hinge connection end 30 of the cover 26 adjacent to the hinge shaft 18, So that the joint 20 is opposed to the tip end of the shaft-

In this state, when the hinge connection end 30 and the hinge shaft 18 are brought close to each other, the hinge shaft 18 enters the shaft hole 33 of the hinge connection end 30. The width D of the shaft hole 34 formed between the tip ends of the shaft forming part 32 is equal to or larger than the distance D 'between the notches 20, (18) can be easily inserted into the shaft hole (33).

Meanwhile, when the hinge shaft 18 is completely inserted into the shaft hole 33, the cover support plate 24 is restored to a circular shape and contacts one surface of the cover body 28. Such a state is shown in Fig. When the cover supporting plate 24 is brought into contact with the cover body 28, the cover body 28 is not subjected to a force enough to elastically deform the cover supporting plate 24, Can not be moved while resiliently deforming the cover support plate (24). That is, the cover support plate 24 prevents the hinge connection end 30 from being separated from the hinge shaft 18.

When the hinge shaft 18 is seated on the shaft hole 33 formed in the cover 26, the cover 26 can be rotated with respect to the hinge shaft 18. The hinge shaft 18 has a curved surface having a predetermined curvature as the abdomen surface 22 except for the cutout portion 20 and the abdomen portion 22 forms the inner surface of the shaft hole 33 Is guided by the inner surface of the shaft guide portion (34) and the shaft forming portion (32) to perform stable rotation.

In particular, shaft guides 34 are formed at both ends of the shaft hole 33 corresponding to both ends of the hinge shaft 18. The shaft guide portions 34 at both ends of the shaft hole 33 are formed at least in a semi- So that the rotation of the hinge shaft 18 can be guided. Of course, since the inner surface of the shaft-shaped portion 32 guides the hinge shaft 18 in a length that is longer in the circumferential direction than the shaft guide portion 34, the guide can be stably guided.

8, the cover 26 is coupled to the main body 10 at an angle of about 120 degrees with respect to the surface of the main body 10, and actually, the hinge shaft 18, The operation is started from the state of FIG. 1 and is operated to a state that is slightly less rotated than the state shown in FIG. Of course, although the cover 26 can be rotated to the state of FIG. 6, the cover 26 is prevented from being separated from the main body 10 by the cover supporting plate 24 even in this state.

In order to separate the cover 26 from the main body 10, the cover 26 is rotated to the maximum extent as shown in FIG. 6, and the cover 26 is rotated as shown in FIG. Elastically deforms the tip. Then, the cover 26 is moved toward the cover supporting plate 24 so that the cutouts 20 pass through the shaft inlet 36 and the hinge shaft 18 is removed from the shaft hole 33. In this state, when the cover 26 is pulled out between the hinge shaft 18 and the cover supporting plate 24, the cover 26 can be completely separated from the main body 10.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention.
