[0001]

[Industrial applications]

 The present invention relates to a screen mounting structure for a projection television.

[0002]

[Prior Art]

 FIG. 3 is a sectional view showing a screen mounting structure of a conventional projection television. In the figure, 1 is a projection television main body, 2 is a screen for transferring an image of a projection television, and 5 is a frame screen for attaching the screen 2 to the projection television main body 1. The frame screen 5 has a contact portion 5b protruding from the flat surface portion 5a at a right angle in a predetermined direction and a U-shaped portion 5c protruding from the flat surface portion 5a in the same direction as the contact portion 5b so as to be able to contact the screen 2. Has been formed. Reference numeral 6 denotes a clip for attaching the screen 2 to the frame screen 5, which has a contact portion 6a which comes into contact with the screen 2 and a U-shaped portion 6b which is inserted into the U-shaped portion 5c of the frame screen 5. FIG. 4 is an enlarged detailed view of the fitting portion between the frame screen 5 and the clip 6. 5d and 5e are protrusions provided inwardly on the U-shaped portion 5c of the frame screen 5 at a predetermined distance from the flat surface portion 5a, and 6c and 6d are bottom portions of the U-shaped portion 6b of the clip 6. Is a protrusion protruding outward at a predetermined distance from.

Next, the operation will be described. As shown in FIG. 3, the screen 2 is arranged inside the plane portion 5a of the frame screen 5 so that one surface contacts the contact portion 5b. When the U-shaped portion 6b is inserted into the U-shaped portion 5c of the frame screen 5 while being in contact with the surface of the U-shaped portion, when the protruding portions 6c and 6c engage with the protruding portions 5d and 5e of the U-shaped portion 5c, the U-shaped portion The clip 6 is held by the frame screen 5 while the clip 6b is compressed inward and passes through the protrusions 5d and 5e, and the contact portion 6a of the clip 6 presses the screen 2 as shown in FIG. The screen 2 is fixed by the elasticity of the frame screen 5 and the clip 6.

[0004]

[Problems to be solved by the device]

 Since the screen mounting structure of the conventional projection television is configured as described above, it is difficult to insert the U-shaped portion 6a of the clip 6 into the U-shaped portion 5c of the frame screen 5, thus improving the efficiency of assembly work. There was a problem of blocking.

The present invention has been made to solve the above problems, and has a screen mounting structure for a projection television, which allows easy insertion of a clip into a frame screen and can securely fix the screen. The purpose is to get.

[0006]

[Means for Solving the Problems]

 In the projection television screen mounting structure according to the present invention, one of the pair of first engaging elements is provided inwardly with the contact portion provided in the same direction substantially at right angles to the plane portion, and the distance from the plane portion is larger than that of the other. A frame screen provided at a large distance, a screen in which one surface of the frame screen is in contact with the contact portion of the frame screen, and the first engaging element inserted in the U-shaped portion of the frame screen. A clip provided with a second engaging element that engages with the flat portion on the side closer thereto and a contact portion that presses the other surface of the screen toward one side.

[0007]

[Action]

 In the projection television screen mounting structure according to the present invention, the second engaging elements engage with the first engaging elements one by one when the clip is inserted.

[0008]

【Example】

 Example 1. A projection television mounting structure according to Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a sectional view showing a screen mounting structure of a projection television according to a first embodiment of the present invention. In the figure, 1 is a projection television main body, 2 is a screen for displaying an image of a projection television, and 3 is a frame screen for attaching the screen 2 to the projection television main body 1. The frame screen 3 is provided with a contact portion 3b protruding from the flat surface portion 3a in a predetermined direction so as to be able to contact the screen 2, and a U-shaped portion 3c protruding from the flat surface portion 3a in the same direction as the contact portion 3b. .. Reference numeral 4 denotes a clip for attaching the screen 2 to the frame screen 3, which has a contact portion 2a which comes into contact with the screen 2 and a U-shaped portion 4b which is inserted into the U-shaped portion 3c of the frame screen 3. FIG. 2 is an enlarged detailed view of the fitting portion between the frame screen 3 and the clip 4. In the figure, 3d and 3e are protrusions provided inwardly on the U-shaped portion 3c of the frame screen 3 at a predetermined distance from the flat surface portion 3a, and the distance from the flat surface portion 3a is one of The protrusion 3d is provided at a position farther than the other protrusion 3e. The protrusions 4c, 4d provided inwardly project outwardly at a predetermined distance from the bottom of the U-shaped portion 4b of the clip 4 and protrudes 3d, 3e of the frame screen 3. And a protrusion provided so as to be capable of engaging with.

Next, the operation will be described. As shown in the figure, the screen 2 is arranged inside the plane portion 3a of the frame screen 3 so that one surface contacts the contact portion 3b, and then the contact portion 4a of the clip 4 is connected to the other surface of the screen 2. When the U-shaped portion 4b is inserted into the U-shaped portion 3c of the frame screen 3 while making contact with, the other protruding portion 4d abuts the protruding portion 3e. At this time, since one of the protruding portions 4c is located away from the protruding portion 3d, when the clip 4 is further pushed, the U-shaped portion 3c is pushed inward by the protruding height of the protruding portion 3c and the protruding portion 3e. The protrusion 4d rides over the protrusion 3e. At this time, the one protruding portion 4c rides over the protruding portion 3d with a delay from the other protruding portion 4d. Thus, when the pair of protrusions 4c and 4d of the clip 4 exceed the protrusions 3d and 3e of the frame screen 3, the contact portion 4a of the clip 4 presses the screen 2, and the screen 2 is connected to the frame screen 3 and the clip. It is elastically held by 4. Here, as shown in FIG. 1, when an external force is applied to the screen 2 in the direction indicated by the arrow 7, a moment as indicated by the arrow 8 is generated, but the protrusions 3d and 4c forming one engaging portion are Since the distance from the flat surface portion 3a is larger than that of the other protruding portions 3e and 4d, the force acting in the direction in which the clip 4 is pulled out is weakened.

[0010]

[Effect of the device]

 As described above, according to the present invention, one of the pair of first engaging members inward is provided with the contact portion provided in the same direction substantially perpendicular to the plane portion, and the distance from the plane portion is larger than that of the other. A frame screen provided at a threshold distance, a screen in which one surface of the frame screen is in contact with the contact portion, and a first engaging element and a flat portion which are inserted into the U-shaped portion of the frame screen. Since the clip is provided with the second engaging element that is engaged on the near side and the contact portion that presses the other surface of the screen toward one side, the clip can be easily inserted and the screen can be inserted. Can be securely held. This has the effect of improving the efficiency of the assembly work.
