Abstract

(57) [Summary] [PROBLEMS] The work efficiency is not good when screwing the top case substantially horizontally from the rear side of the chassis, and the front case is screwed when screwing the top case substantially vertically. The positional relationship with the panel was not determined, and a gap was formed between the front panel and the top case, which sometimes made the appearance unsightly. SOLUTION: When an operator inserts a screw A into a screw hole 43 and tightens the screw A into a screw hole 24, the upper edge of a cylindrical body 25 guides a top case 40 upward along an inclined surface 44. The case 40 is pressed toward the front side relative to the chassis 20, and the gap B formed between the front panel 30 and the top case 40 before screwing is eliminated, thereby deteriorating the work efficiency. Therefore, it is possible to prevent a gap from being generated between the front panel 30 and the top case 40.

[0002]

[Prior art]

 Conventionally, a top case is assembled to a substantially chassis-shaped chassis having openings on the front side and top side, and a front panel that is assembled while being positioned on this chassis and seals the opening on the front side. When the opening is sealed, the top case is screwed from the rear side of the chassis to prevent a gap from being formed between the front panel and the top case. In another case, a claw portion that can be fitted to each other is formed on each of the top case and the chassis, and a screw hole provided with a screw hole that can be screwed from a vertical direction while communicating with each other. The projection is oriented from the top case and the chassis to the side facing each other so that they can be fitted to each other.

With such a configuration, when each claw portion and each screw hole projection are fitted to each other and screwed in the vertical direction, the top case is assembled while being positioned on the chassis. As a casing structure of this type, a casing structure applied to a fixing structure of an electronic device housing disclosed in Japanese Utility Model Registration No. 3031834 is known.

[0004]

[Problems to be solved by the invention]

 The conventional casing structure described above has the following problems. In the case of the former, work efficiency was not good because screws had to be screwed in a substantially horizontal direction from the rear side of the chassis. On the other hand, in the latter case, only the positioning of the top case with respect to the chassis can be performed, and the positional relationship between the front panel and the front panel is not determined, and a gap is formed between the front panel and the top case. This caused the appearance to be unsightly. The present invention has been made in view of the above problems, and has as its object to provide a casing structure capable of preventing a gap from being formed between a front panel and a top case without deteriorating work efficiency. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 is a chassis having a substantially housing shape having an opening on a front side and an upper side, and is assembled while being positioned on the chassis to seal the opening on the front side. In a casing structure including a front panel and a top case assembled to the chassis and sealing an opening on the upper surface side, the chassis and the top case are screwed in a substantially vertical direction while communicating with each other. Each has a possible screw hole, between the upper surface side of the chassis and the lower surface side of the top case, an inclined surface that inclines upward from the front side to the rear side, A slide portion for guiding the top case along the inclined surface while pressing the top case toward the front panel is formed. In the invention according to claim 1 configured as described above, the front panel is assembled while being positioned from the front side of a substantially housing-shaped chassis having openings on the front side and the top side, and the front panel is opened. Is sealed.

Then, the top case is assembled to the chassis and the front panel by screwing the chassis and the top case to each other and screwing in a substantially vertical direction while communicating the screw holes of the chassis with the top case. Is sealed. At this time, when the screws are screwed, the top case is guided by the slide portion while being pressed toward the front panel along the inclined surface that is inclined upward from the front side to the rear side. A gap is hardly generated between the top case and the front panel.

The casing structure is suitable as a casing for an electric appliance such as a video deck, but is not limited to such a use from the viewpoint that it can be used as a casing, and can be applied to all fields. The front panel is assembled while being positioned on the chassis and only needs to be able to seal the front opening of the chassis. It may be one that is locked by using a claw body formed on the base.

The top case may be any one that is assembled to the chassis and seals an opening on the upper surface side of the chassis, and may be assembled only to the chassis. It may be mounted on the front panel. The screw holes are formed in the chassis and the top case, respectively, as long as they can be screwed in a substantially vertical direction while communicating with each other, and the arrangement position and number thereof can be appropriately changed. . Further, since it is sufficient that the above-mentioned chassis and the top case can be assembled, a screw thread which can screw a screw may be formed on an inner wall of a screw hole formed on the side of the chassis. A screw hole having a smaller diameter than the diameter may be formed and the screw may be screwed.

Since the inclined surface and the slide portion may be formed between the upper surface of the chassis and the lower surface of the top case, the inclined surface is formed on the side of the chassis. The sliding portion may be formed on the side of the top case, or the inclined surface may be formed on the side of the top case, and the sliding portion may be formed on the side of the chassis. As an example of the configuration in the latter case, the invention according to claim 2 is directed to the casing structure according to claim 1, wherein the top case is formed with a concave portion having the inclined surface, and the chassis is formed in the chassis. The slide portion for guiding the top case upward on the rear side along the inclined surface is provided so as to protrude substantially upward. In the invention according to claim 2 configured as described above, when screwing is performed, the slide portion protruding from the chassis side moves along the inclined surface of the concave portion formed on the top case side. In order to guide the top case upward on the rear side, the top case is pressed toward the front panel.

[0010] As described above, when the concave portion having the inclined surface is formed and the slide portion is protruded, it is a proper example in that the efficiency at the time of the molding operation is high, but the inclined surface is formed on the side of the top case. However, from the viewpoint that it is only necessary to form a slide portion on the chassis side, a protrusion having an inclined surface is formed on the top case side, and a recess having a slide portion is formed on the chassis side. It is also possible to form. Here, the slide portion may be any one that guides the top case upward on the back side along the inclined surface, and may be formed only around the screwed portion. It may be arranged on the side substantially perpendicular to the pressing direction of the top case irrespective of the screwing position. Further, the slide portion may be formed continuously in a substantially band shape on a side substantially orthogonal to the pressing direction of the top case.

[0011] As an example of the configuration of the slide portion in the former case, the invention according to claim 3 is directed to the casing structure according to any one of claims 1 and 2, wherein the slide portion is provided at an upper peripheral edge. The portion is formed by a substantially cylindrical body having the screw case on the axis while the top case can be guided upward on the back side along the inclined surface. In the invention according to claim 3 configured as described above, when a screw is formed in a screw hole formed on the axis of the substantially cylindrical body, a peripheral edge of an upper end of the substantially cylindrical body is formed along the inclined surface. In order to guide the top case upward on the rear side, the top case is pressed toward the front panel.

An additional structure may be provided at the peripheral edge of the upper end of the substantially cylindrical body so as to be smoothly guided along the inclined surface, and an example of such a configuration is according to claim 4. According to the present invention, in the casing structure according to the third aspect, the substantially cylindrical body has an inclined surface substantially parallel to the inclined surface at an upper peripheral portion thereof. In the invention according to claim 4 configured as described above, when screwing is performed, the inclined surface substantially parallel to the inclined surface formed on the peripheral edge of the upper end of the substantially cylindrical body is rearward along the inclined surface. You are guided upward.

[0013]

[Effect of the invention]

 As described above, according to the present invention, when screwing is performed in a substantially vertical direction, the top case is pressed toward the front panel, so that the front panel and the top case can be connected without deteriorating work efficiency. It is possible to provide a casing structure capable of preventing a gap from being generated therebetween. According to the second aspect of the present invention, since the recess having the inclined surface is formed and the slide portion is protruded, the molding efficiency can be improved.

Further, according to the invention of claim 3, since the screw hole and the slide portion can be provided at the same place, the molding efficiency can be improved. Further, according to the invention of claim 4, it is possible to smoothly guide the peripheral edge of the upper end of the substantially cylindrical body along the inclined surface at the time of screwing.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a casing of a video deck according to an embodiment of the present invention.

The casing 10 is provided with a chassis 20 having a substantially housing shape having openings on the front side and the upper side. The chassis 20 accommodates a tape drive mechanism, a control board, and the like (not shown). . On the front side of the chassis 20, a front panel 30 on which an operation panel, a video tape insertion slot and the like are arranged is assembled, and the front side opening is sealed.

As shown in FIG. 1, cylindrical bodies 21 to 23 having through holes from the front side to the rear side of the chassis 20 are integrally formed inside the peripheral edge of the front side opening of the chassis 20. Then, three flexible claw bodies 31 to 33 protruding from the rear side of the front panel 30 are engaged with each other while being inserted therethrough. Since each of the cylinders 21 to 23 and each of the claw bodies 31 to 33 have the same shape, the cylinder 21 and the claw 31 will be specifically described as an example. The tip of the claw 31 is shown in FIG. Thus, the tip is inserted into the cylindrical body 21 as shown in FIG. 3 while the claw body 31 is bent toward the inner wall surface of the chassis 20. Then, when the rear side of the front panel 30 contacts the front side of the chassis 20 and the tip of the claw body 31 comes off to the back side of the cylindrical body 21, the claw body 31 is pushed upward by the restoring force. As shown in (2), the tip of the claw body 31 is locked in the opening on the back side of the cylindrical body 21.

The claw members 32 and 33 are similarly locked at the lower side and the left and right sides of the front side opening of the chassis 20, so that the front panel 30 is attached to the chassis 20 as shown in FIG. It will be positioned. The top opening of the chassis 20 is sealed by assembling the top case 40 to the chassis 20 and the front panel 30 as shown in FIG. The top case 40 has claw bodies 41, 41 protruding from the front side, positioning protrusions 42, 42 protruding downward from the lower surface, and screw holes 43 formed substantially vertically in the rear side. , 43 are provided.

With this configuration, the pawl bodies 41, 41 are inserted from the rear side of the front panel 30 to adjust the heights of the upper wall surfaces of the front panel 30 and the top case 40. The left and right outer wall surfaces of the chassis 20 and the left and right side wall surfaces of the top case 40 are aligned by contacting the inner walls of the left and right edges of the upper surface opening. Then, the screw holes 24, 24 formed in a substantially vertical direction on the back side of the opening on the upper surface side of the chassis 20 are communicated with the screw holes 43, and screwing is performed from above.

As shown in FIG. 6, the screw holes 24, 24 are formed on the axis of the cylindrical bodies 25, 25 protruding upward from the upper edge of the opening on the upper surface of the chassis 20. On the front side of the lower opening 43, inclined surfaces 44 and 44 are formed, which are gradually inclined downward toward the front side. Therefore, by placing the top case 40 on the upper surface side of the chassis 20, the cylindrical body 25 is pressed against the inclined surface 44 as shown in FIG. 7, and the screw A formed with a diameter larger than the screw diameter is formed. When the screw is tightened into the screw hole 24 while being inserted into the hole 43, the top edge of the cylindrical body 25 guides the top case 40 upward along the inclined surface 44 as shown in FIG. 9, the upper end of the cylindrical body 25 contacts the horizontal surface 45 formed on the lower surface of the top case 40 as shown in FIGS. 9 and 10.

At this time, since the top case 40 is pressed toward the front side relative to the chassis 20, the gap B formed between the top case 40 and the front panel 30 before screwing as shown in FIG. Is resolved as shown in FIG. Here, the upper edge of the cylindrical body 25 that guides the top case 40 upward along the inclined surface 44 constitutes a slide portion in the present invention in this sense.

In the present embodiment, the top case 40 is guided along the inclined surface 44 by the corners formed at the upper end edge of the cylindrical body 25. However, as shown in FIG. By providing the inclined surface 25a substantially parallel to the inclined surface 44, smooth guidance can be realized. That is, similarly to the case described above, when the screw A is tightened into the screw hole 24 while being inserted into the screw hole 43, the top case 40 is moved upward along the inclined surface 44 by the inclined surface 25a as shown in FIG. When the screwing is completed, the upper end of the cylindrical body 25 is brought into contact with a horizontal surface 45 formed on the lower surface of the top case 40 as shown in FIG. In the above description, the casing structure according to the present invention is applied to the casing of a video deck, but from the viewpoint that the application field is not limited, the casing structure can be used for casings in all fields. is there.

Next, an operation of assembling the casing 10 of the video deck according to the present embodiment will be described. After the operator accommodates the tape drive mechanism and the control board in the chassis 20, as shown in FIG. 1, the rear side of the front panel 30 is turned to the front side opening of the chassis 20, and the claws 31 to 33 are moved. When pushed in from the front side openings of the cylinders 21 to 23, the claws 31 to 33 are inserted into the cylinders 21 to 23 while bending toward the inner wall surface of the chassis 20, as shown in FIG. When the tips of the claws 31 to 33 are pulled out to the rear side of the cylinders 21 to 23, the claws 31 to 33 are pushed back by the restoring force, as shown in FIG. As shown in FIG. 5, the front panel 30 is assembled with the chassis 20 while being positioned with respect to the chassis 20 so as to be engaged with the side openings.

Then, the operator inserts the pawl members 41, 41 from the rear side of the front panel 30, and abuts the positioning projections 42, 42 against the inner walls of the left and right edges of the opening on the upper surface side of the chassis 20. The top case 40 is placed on the upper surface side opening of the chassis 20. As shown in FIG. 6, when the screw A is inserted into the screw hole 43 and tightened into the screw hole 24 as shown in FIG. Since the case 40 is guided upward and the top case 40 is pressed toward the front panel 30 as shown in FIG. 11, when screwing is completed, as shown in FIG. Thus, the gap B formed between the top case 40 and the front panel 30 is eliminated. As described above, when the operator inserts the screw A into the screw hole 43 and tightens the screw A into the screw hole 24, the upper edge of the cylindrical body 25 guides the top case 40 upward along the inclined surface 44. In addition, the top case 40 is pressed toward the front surface relative to the chassis 20, and the gap B formed between the front panel 30 and the top case 40 before screwing is eliminated. It is possible to prevent the occurrence of a gap between the front panel 30 and the top case 40 without deterioration.
