  Thin displays (hereinafter referred to as “thin displays”) such as liquid crystal displays, plasma displays, organic EL displays, and field emission displays, which are becoming mainstream in recent years instead of CRTs, are thin because of the trend toward larger TVs and the like. The size of the display is also increasing, and the metal display frame for mounting and shielding these on equipment is also increasing in size. Conventionally, in such a thin display frame (hereinafter simply referred to as “frame frame”), the blank is a metal plate before punching, and the whole is integrally punched into a generally rectangular outer shape, and an opening is formed on the inside to match the screen. The frame was formed by press-molding the metal plate formed by this punching process. The punched part was treated as waste. However, in order to integrally form the entire frame by increasing the size of the thin display, a large press device is required, and the equipment becomes large, and a press die adapted to various screen sizes is also required. . Further, there is a problem that the blank that is punched out is wasted.

Therefore, as in the invention described in Patent Document 1 shown in FIG. 15, a plurality of divided frames 102a, 102b, 102c, 102d are punched in advance and formed into an L-shaped cross section, and these are integrated into a rectangular shape by welding. A frame frame 101 has been proposed that forms the shape of Further, Patent Document 2 includes one or a plurality of convex portions and concave portions having a constricted portion at an end portion of a metal plate that is divided into two at a corner portion and punched into a substantially L shape by a press. There has been proposed a method of providing a frame frame for holding a display by providing a fitting locking portion and fixing it by caulking from above and below, and then bending the fitting locking portion.

Further, the lower straight connection portion 3e is provided on the left side and the lower right connection portion 3f is provided on the right side in the lower straight line portion. The right straight portion is provided with a lower right connecting portion 3g on the lower side and an upper right connecting portion 3h on the upper side. By these connection portions 3a to 3h (hereinafter, simply referred to as “connection portion 3” when not particularly distinguished), the frame 1 can be divided into eight.

  The frame frame 1 thus divided has an upper right divided frame 2a including an upper right corner, an upper left divided frame 2c including an upper left corner, and an upper divided frame 2b between the upper straight portions therebetween. Further, it has a lower right divided frame 2g including a lower right corner, a lower left divided frame 2e including a lower left corner, and a lower divided frame 2f of a lower linear portion therebetween. And it has the right divided frame 2h of the right straight part and the left divided frame 2d of the left straight part. The above eight divided frames 2a to 2h (hereinafter, simply referred to as “divided frame 2” when not particularly distinguished) are manufactured separately and connected to each other by a connecting portion 3 to form a completed frame frame 1.

  (Connection part) Next, the connection part 3 which is the principal part of this invention is demonstrated in detail. As shown in FIG. 4, the connection part 3 consists of the fitting part 5 shown in FIG. 3, and the to-be-fitted part 4 shown in FIG.

  (Fitted part) As shown in FIG. 2, the fitted part 4 is formed integrally with one of the divided frames 2 connected to each connecting part 3 (see FIG. 4). The fitted portion 4 has a plate-like insertion portion 41 having a pair of parallel side end faces 42 and 42 along the insertion direction indicated by an arrow.

(Fitting part) On the other hand, the fitting part 5 is formed integrally with the other divided frame 2 of the connecting part 3 (see FIG. 4).
(Guide part) The fitting part 5 has the four guide parts 51 which guide the side end surfaces 42 and 42 parallel when inserting the insertion part 41. FIG. As shown in FIG. 5, the guide portion 51 is integrally formed on the metal plate of the fitting portion 5, and is protruded from the fitting portion 5 so as to guide the insertion portion 41 from both sides on the side end face 42. It is a member formed in an L-shaped cross section. The pair of guide portions 51, 51 are provided so that their tips are opposed to each other. Moreover, the guide parts 51 and 51 are provided in a total of two pairs and four places along an insertion direction, as shown in FIG. For this reason, the guide part 51 restrict | limits the insertion part 41 correctly in the direction orthogonal to an insertion direction, and maintains the insertion part 41 in an exact position.

  (Stopper portion) Next, the stopper portion 6 that restricts insertion by bringing the insertion portion 41 into contact with a predetermined position of the fitting portion 5 will be described with reference to FIG. As shown in FIG. 6, the stopper portions 6, 6 are integrally disposed on the metal plate of the fitting portion 5 at a contrasting position with respect to the central axis along the longitudinal direction of the divided frame 2, and the insertion direction Stopper portions 6 and 6 that are rectangular tongue-shaped members are formed so that the end portions come in the opposite directions. The tip portions 61 and 61 of the stopper portions 6 and 6 are formed so as to protrude from the surface of the fitting portion 5 by about half of the plate thickness. The front end portions 61 and 61 are formed with a surface orthogonal to the insertion direction, and the two front end portions 61 and 61 are formed on the same surface. For this reason, it comes into surface contact with the distal end surface 43 of the insertion portion 41 on the insertion direction side. In the present application, a position where the tip surface 43 and the tip portions 61 and 61 are in surface contact is referred to as a lock position.

Thus, the stopper parts 6 and 6 make the front-end | tip parts 61 and 61 contact | abut to the front-end | tip of the insertion part 41, and regulate the relative displacement of the insertion part 41 in a locked position correctly.
(Lock part)
Next, the lock part 7 which fixes the connection part 3 in a lock position is demonstrated. As shown in FIG. 6, the lock portion 7 is inserted into the fitting portion 5 with the fitting portion 5 and the fitted portion 4 being fitted to the fitting portion 5 at the locked position. The relative displacement in the removal direction opposite to is regulated and fixed.

The lock part 7 maintains a locked state by mutually latching on either one of the divided frames 2 respectively connected by the connection parts 3.
In the present embodiment, as shown in FIGS. 3 and 6, claw-shaped hooking claws 71 as four hooking parts are provided between the guide parts 51, 51 of the fitting part 5.

  A pair of latching claws 71 are disposed integrally with the metal plate of the fitting portion 5 at a contrasting position with respect to the central axis along the longitudinal direction of the divided frame 2, and a pair is further added at a position shifted in the insertion direction. In four places. The four hooking claws 71, which are rectangular leaf spring-like members, are formed so that the end portions are oriented in the insertion direction. The front end 72 of each latching claw 71 is formed so as to protrude to the surface side into which the insertion portion 41 enters about half the plate thickness. Each tip 72 is formed on a surface orthogonal to the insertion direction.

  On the other hand, as shown in FIG. 2, the insertion portion 41 of the fitted portion 4 has a window-like latching window 73 as a latched portion at a position corresponding to each of the four latching claws 71 in the locked position. It is open.

  Further, as shown in FIG. 6, the edge portion 74 on the insertion direction side of the latching window 73 is disposed so as to coincide with the distal end portion 72 of the latching claw 71 at the lock position. 5 and 6 show the thickness exaggerated for the sake of explanation, but in actuality, the inclination of the latching claw 71 is very small, and the gap between the tip 72 and the edge 74 is also very small. It maintains the locked position accurately without play.

(Step part)
When the divided frames 2 are connected, the fitting portions 5 and the fitted portions 4 constituting the respective connecting portions 3 are connected in an overlapping manner, but the surfaces of the respective divided frames 2 may be flush with each other. desirable. Therefore, in the present invention, the step corresponding to the plate thickness is adjusted so that the surfaces of the respective divided frames 2 are flush with each other.

  In the embodiment, as shown in FIG. 6, the insertion portion 41 has a stepped portion 8 that is stepped and bent in the thickness direction so that a step corresponding to the plate thickness is formed at the proximal end portion of the insertion portion 41. It is formed. The stepped portion 8 is flush with the other divided frame 2 provided with the fitting portion 5 when the frame 1 is assembled, and the surface excluding the inserted portion 41 of the divided frame 2 on which the inserted portion 41 is formed. It is formed to become.

(Production method)
Next, a method for manufacturing the divided frame 2 configured as described above will be described. Each divided frame 2 is first punched with a press from a blank (metal plate) as a material. The material of the metal plate is SUS material in this embodiment, but it can be sheared and plastically deformed by a press machine, and if it has elasticity that functions as a leaf spring when the latching pawl 71 is formed, it can be iron-based or magnesium depending on the application. Various materials such as titanium and titanium are used. In addition, although the thickness of the metal plate depends on the size of the frame 1, in the embodiment, the metal plate is manufactured with a plate thickness of about 0.5 mm to 1.0 mm. Further, the frame fixing hole 13 and the display fixing hole 14 (see FIG. 1) are also drilled by the press machine. These shape punching can be divided and integrated into a plurality of processes as required. The structure of the connection part 3 is also formed at this time. As shown in FIG. 7, the latching pawls 71 of the stopper portion 6 and the lock portion 7 are cut and bent, and are bent about half the plate thickness. The term “cut bending” as used herein refers to shearing with a press machine while leaving a part, and bending without giving a large plastic deformation.

  Specifically, a punch 93 having a tip formed on an inclined surface at the fitting portion 5 of the divided frame 2 set on the die 91 (lower die) and held by the stripper plate 92 is lowered and sheared into a U-shape. At the same time, the nail-like portion is pressed downward to be plastically deformed. The stopper portion 6 and the latching claw 71 protrude from the surface of the metal plate of the fitting portion 5 by about half of the plate thickness. When the punch 93 is lifted, the stopper portion 6 and the hooking claw 71 return due to the spring property, but the tip portions 61 and 72 are plastically deformed to the extent that they are bent about half of the plate thickness. Since this metal plate has elasticity, if the latching claw 71 is pressed from below, it bends to the same surface as the fitting portion 5. On the other hand, even if the stopper portion 6 is pressed horizontally from the tip portion 61 side or the latching claw 71 is pressed horizontally from the tip portion 72 side, the stopper portion 6 and the latching claw 71 are hardly deformed. Further, by processing in this way, the tip portions 61 and 72 are formed at accurate positions along the insertion direction.

  As shown in FIG. 8, the guide portion 51 is cut into a U shape and then bent twice by 90 degrees to form an L shape. As used herein, the bending process refers to a process in which a part is left sheared by a press machine and is largely plastically deformed to be bent. Specifically, prior to the step shown in FIG. The sheared nail-like portion is raised so as to be perpendicular to the fitting portion 5 once. As shown in FIG. 8, the lower end of the guide portion 51 is fitted to the fitting portion 5 by the punch 96 and the movable die 97 on the fitting portion 5 of the divided frame 2 set on the die 94 (lower die) and pressed by the stripper plate 95. In parallel with each other and so as to form a gap corresponding to the thickness of the insertion portion 41. Here, an example is schematically shown, but it goes without saying that processes can be divided and integrated, and the order is not limited.

  By processing in this way, the guide part 51 can be formed at an accurate position in a direction orthogonal to the surface of the fitting part 5. At this time, the gap between the surface of the fitting portion 5 and the tip of the guide portion 51 is about 0.05 mm larger than the thickness of the insertion portion 41, and the position of the insertion portion 41 is regulated by the guide portion 51. And slides smoothly.

  Although not shown, the step portion 8 is formed by step bending, and according to this processing method, the position accuracy of the insertion surface 41 in the insertion direction of the distal end surface 43 is maintained and the direction orthogonal to the surface of the fitted portion 4 is maintained. Is accurately offset by the plate thickness.

In addition, the holding portion 12 is bent 90 degrees with respect to the main body portion 11, and the entire divided frame 2 has a substantially L-shaped cross-sectional shape.
The assembly of each divided frame 2 thus manufactured will be described. Each divided frame 2 can be easily connected by simply inserting it in each connecting portion 3 by hand, and no special tool or equipment is required.

  As shown in FIG. 9, when the divided frames 2 a to 2 h constituting the frame 1 are arranged at predetermined positions, the fitting portion 5 and the fitted portion 4 are arranged at positions facing each other. And when connecting each fitting part 5 and the to-be-fitted part 4, the insertion part 41 shown in FIGS. When the insertion portion 41 is moved relative to the fitting portion 5 in the insertion direction, the hooking claw 71 protruding from the surface of the fitting portion 5 is pressed by the insertion portion 41 and elastically deformed to be aligned with the surface of the fitting portion 5. It becomes flush and does not hinder the entry of the insertion part 41. When the insertion portion 41 is further inserted, the distal end surface 43 of the insertion portion 41 comes into contact with the distal end portions 61 and 61 of the stopper portions 6 and 6. The tip portions 61 and 61 are formed with high positional accuracy in the insertion direction by cutting and bending as described above, and the four guide portions 51 accurately position the insertion portion 41 in the direction orthogonal to the insertion direction. For this reason, the insertion portion 41 is guided to an accurate lock position. At this time, the four latching windows 73 of the insertion part 41 are accurately aligned with the four latching claws 71 of the fitting part 5. Then, as shown in FIG. 6, the tip 72 of the latching claw 71 that has been elastically deformed enters the corresponding latching window 73 and abuts against the edge 74. Therefore, the insertion portion 41 is restricted from moving in the direction opposite to the insertion direction and is fixed to the fitting portion 5. That is, each divided frame 2 is fixed in an accurate positional relationship as shown in FIG. 10 simply by being inserted into the corresponding divided frame 2.

In addition, when it assembles by mistake, if the four latching claws 71 are pressed simultaneously from the latching window 73, latching can be cancelled | released and the insertion part 41 can be extracted.
(Modification)
