Meanwhile, the frames 110 and the notice 1 may be protected and overall strength of the picture frame 100 may be reinforced by disposing a back plate (not shown) having a certain thickness at a rear region of the frames 110.

The number of fixing units 120 required on the combining groove 112 of the frame 110 are provided such that the notice 1 is easily replaced, fixed, and stretched out. The number of fixing units 120 may correspond to the number of fixing holes 2 of the notice 1.

FIG. 5 is a detailed diagram of a region A of FIG. 3, and illustrates the fixing unit 120 disposed on the frame 110. Here, the detailed diagram of FIG. 5 is a bottom perspective view for easy understanding of a shape of the fixing unit 120.

FIG. 6 is an exploded perspective view of a structure of the fixing unit 120 used in an embodiment of the present invention.

Referring to FIGS. 5 and 6, the fixing unit 120 used in an embodiment of the present invention includes a body 130, a rotor 140, and an elastic unit 150.

The body 130 has a rectangular parallelepiped shape having a certain size, and enables the fixing unit 120 to be continuously disposed on the combining groove 112.

A connection groove 132 into which a top of the combining groove 112 is inserted is formed on a side surface of the body 130, at a certain width and depth.

Accordingly, the body 130 may be disposed at a certain location on the combining groove 112 according to demands of a user.

The rotor 140 has a plate shape having a certain length and width. One end of the rotor 140 is connected to one end of the body 130 via a shaft. The other end of the rotor 140 includes a hook 142 that is inserted into and hooked to the fixing hole 2.

Here, the rotor 140 is rotatably connected on the body 130, and thus may rotate at a certain angle by the user.

One end of the body 130 includes a first shaft 134.

The first shaft 134 has a pipe shape having a certain diameter and height, and a second shaft 144 described later is inserted into the first shaft 134.

One end of the rotor 140 includes the second shaft 144.

The second shaft 144 has a cylindrical shape having a certain length and diameter, and is inserted into the first shaft 134. The diameter of the second shaft 144 may correspond to an internal diameter of the first shaft 134.

The rotor 140 may be detachably connected to the body 130.

FIG. 7 is a perspective view for describing a mutual relationship between the first shaft 134 and the second shaft 144 of the fixing unit 120 used in an embodiment of the present invention. The first shaft 134 includes an elastic unit, but for easily description of the mutual relationship between the first shaft 134 and the second shaft 144, the elastic unit is not illustrated.

Structures of the first and second shafts 134 and 144 will now be described with reference to FIG. 7.

A first hooking end 145 having a rod shape in a certain diameter and length is formed at one side of an end of the second shaft 144 in a direction perpendicular to the second shaft 144.

A first insertion groove 135 into which the first hooking end 145 is inserted is formed at one side of the first shaft 134.

The first insertion groove 135 is formed from top to bottom of the first shaft 134. Here, a width of the first insertion groove 135 may be uniform from top to middle of the first shaft 134 while corresponding to a diameter of the first hooking end 145. Also, the width of the first insertion groove 135 may increase from the middle of the first shaft 134. Accordingly, the first insertion groove 135 may have an L shape in overall.

Accordingly, when the second shaft 144 is inserted into the first shaft 134 and then rotated, the first hooking end 145 is located below the first insertion groove 135, and thus the second shaft 144 may be prevented from being detached from the first shaft 134.

Referring back to FIGS. 5 and 6, first and second fixing ends 136 and 146 protrude respectively from surfaces of the body 130 and the rotor 140, which face each other.

The first fixing end 136 protrudes from a side end of the body 130.

The second fixing end 146 protrudes from a side end of the rotor 140 while protruding from a location facing the first fixing end 136 protruding from the body 130. Two ends of the elastic unit 150 having a certain height and a hexahedron shape described later are respectively fixed at the first and second fixing ends 136 and 146.

According to the current embodiment, it is described that the first fixing end 136 protrudes from the body 130 and the second fixing end 146 protrudes from the rotor 140, but the first fixing end 136 may protrude from the rotor 140 and the second fixing end 146 may protrude from the body 130.

The elastic unit 150 is disposed on a shaft where the body 130 and the rotor 140 are connected, and applies elastic force to the rotor 140. The elastic unit 150 used in the current embodiment includes a coil spring. Hereinafter, it is assumed that the elastic unit 150 is a coil spring, and the same reference numeral is used.

The coil spring 150 is disposed to surround an outer circumference of the first shaft 134. Accordingly, a diameter of the coil spring 150 may correspond to a diameter of the first shaft 134.

Two ends of winding of the coil spring 150 may respectively extend towards the first and second fixing ends 136 and 146, and may be respectively fixed to the first and second fixing ends 136 and 146. Accordingly, the coil spring 150 may apply elastic force to the body 130 and the rotor 140 through the first and second fixing ends 136 and 146. Here, since the body 130 is disposed on the combining groove 112, only the rotor 140 may rotate in a certain direction by the elastic force.

Here, a rotation preventing end 138 may protrude from one side of the body 130 such that rotating of the rotor 140 is restricted. A hooking groove 148 may be formed on the rotor 140 at a location corresponding to the rotation preventing end 138.

FIG. 8 is a diagram of a fixing unit 120A used according to another embodiment of the present invention.

Referring to FIG. 8, the fixing unit 120A disposed at a corner portion of the picture frame 100 may include a body 130A having a shape corresponding to a corner shape of the picture frame 100.

Since a structure of the fixing unit 120A is the same as that described above except for the shape of the body 130A, details thereof are not provided again.

FIG. 9 is a diagram for describing how an embodiment of the present invention is used.

The notice 1 is prepared. The notice 1 includes the plurality of fixing holes 2 along the edge of the notice 1.

Here, the fixing unit 120 is disposed on the picture frame 100 at a location corresponding to the fixing hole 2. Also, the number of fixing unit 120 corresponds to the number of fixing holes 2.

An operator locates the notice 1 at a location A1. Then, the operator rotates the rotor 140 to be disposed at a location A2 such that the hook 142 is hooked to the fixing hole 2.

Next, when the operator removes force applied to the rotor 140, the rotor 140 rotates to a location B2 according to elastic force of the coil spring 150, and the notice 1 moves to a location B1.

When the fixing units 120 are respectively fixed to the fixing holes 2 of the notice 1, the notice 1 may stretch out and be posted according to the elastic force of the coil spring 150 included in the fixing unit 120 of the notice 1.

When the notice 1 is to be replaced, operations may be performed in a reverse order of fixing the notice 1.
