Description

  The present invention relates to a panel fixing structure for fixing a panel to a plate material with screws, and in particular, a fixing structure for fixing an exterior resin cover to a sheet metal frame of a casing of an automatic transaction apparatus, and automatic transaction using this fixing structure Relates to the device.

  Conventionally, a fixing structure for fixing a cover, which is a resin member, to a sheet metal part, which is a part of an automatic transaction apparatus, has been developed (see Patent Document 1). Here, an outline of the fixing structure described in Patent Document 1 (hereinafter sometimes referred to as “conventional fixing structure”) will be described with reference to FIG. 10.

  The conventional fixing structure is provided inside a plate nut 902 that is rectangular as shown in FIG. 10 and a cover 901 that is a resin member in consideration of conditions such as mounting space due to the relationship with other components. The mounting portion 911 that accommodates the plate nut 902 is mainly provided.

JP 2010-266035 A (paragraphs 0012 to 0021, FIGS. 1 to 4 etc.)

  However, the technique described in Patent Document 1 has been required to improve the following problems. This problem will be described with reference to FIGS.

First, since the width of the mounting hole 911g is the same value as the dimension x of the long side of the plate nut 902, the mounting portion 911 has the plate nut 902 rotated in the wrong direction (90 ° shown in FIG. 11). Orientation), there was a problem that it could be inserted into the mounting portion 911.
If the plate nut 902 is inserted in the wrong direction, the plate nut 902 is skewed in the mounting portion 911, and the plate nut 902 can be removed simply by hooking it with a finger using the extraction hole 911h of the mounting portion 911. There was a further problem that could be difficult. In this case, the plate nut 902 cannot be taken out without using a tool.

  Second, as shown in FIG. 12, in the state where the plate nut 902 is inserted, the opening end surface 911i on the insertion side of the mounting portion 911 and the end surface 902i on the rear end side of the plate nut 902 are the same surface. In this case, simply pressing the plate nut 902 does not allow complete insertion (insertion) into the mounting portion 911, resulting in a poor insertion. On the other hand, although not shown, the plate nut 902 is inserted even when the opening end surface 911 i on the insertion side of the mounting portion 911 and the end surface 902 i on the rear end side of the plate nut 902 are not flush with each other. There arises a problem that it is not known whether or not 902 is securely inserted into the mounting portion 911. These are particularly problematic when the insertion load (such as the frictional force between the mounting portion 911 and the plate nut 902) is large.

  Thirdly, when the gap between the plate nut 902 and the mounting portion 911 is large, depending on the handling of the cover 901 as a panel, the plate nut 902 to be screwed with the plate material may be displaced in the mounting portion 911 due to its own weight. There was a problem of falling from the part 911.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a panel fixing structure that can reliably fix a panel to a plate material and an automatic transaction apparatus using the panel fixing structure. To do.

With reference to FIG. 1, the structure of the panel fixing structure which concerns on 1st Embodiment is demonstrated. Here, FIG. 1 is an exploded perspective view showing the overall configuration of the panel fixing structure A according to the first embodiment. The panel fixing structure A shown in FIG. 1 is for fixing the cover 1 which is a panel to the sheet metal part 3 which is a plate material. Here, the sheet metal part 3 is, for example, a sheet metal frame of an automatic transaction apparatus (ATM), and the cover 1 is, for example, a front cover (decorative panel) of the automatic transaction apparatus (ATM).

  The panel fixing structure A mainly includes a cover 1, a plate nut 2, a sheet metal part 3, a flange collar 4, a washer 5, an E ring 6, and a screw 7. In the present embodiment, the cover 1 and the sheet metal part 3 are fixed at two locations. However, the present invention is not limited to this and may be fixed at, for example, three or more locations.

(cover)
The cover 1 is a member that decorates the appearance of a housing (not shown), and is formed of a synthetic resin material. As shown in FIG. 1, two attachment portions 11, 11 for attaching the plate nut 2 are integrally formed on the back surface 1 a of the cover 1 (the surface not exposed to the outside of the housing). The attachment portions 11, 11 are formed at positions corresponding to attachment holes 31, 32 formed at a predetermined interval in the longitudinal direction of the sheet metal part 3.

  With reference to FIG. 2 thru | or FIG. 4, the structure of the attaching part 11 is demonstrated. Here, FIG. 2 is an exploded perspective view in which the attachment hole 31 side of the panel fixing structure A is enlarged. FIG. 3 is a diagram (perspective view) showing a state of the attachment portion 11 to which the plate nut 2 is attached. FIG. 4 is a diagram (longitudinal sectional view) showing a state of the attachment portion 11 to which the plate nut 2 is attached.

  The attachment portion 11 includes three bottom walls 11a extending along the back surface 1a of the cover 1, an upper wall 11b disposed to be opposed to the bottom wall 11a, and a bottom wall 11a and the upper wall 11b. It is mainly comprised from the side walls 11c-11e. Thereby, the attachment part 11 has the attachment hole 11g in which the plate nut 2 is inserted from the opposite side of the side wall 11e. The mounting hole 11g has a rectangular shape in plan view. Note that the side wall 11 e serves as a rib of the attachment portion 11.

  Further, the attachment portion 11 is formed with an extraction hole 11h that is used when the plate nut 2 is extracted from the attachment hole 11g in the upper wall 11b. The extraction hole 11h has a U-shape in plan view, and extends from one end (the end on the side wall 11e side) of the upper wall 11b to the vicinity of the other end (the end on the opening end surface 11i side where the mounting hole 11g opens), and It is integrally formed from the upper end part of the side wall 11e to the height of the bottom wall 11a. The extraction hole 11h is formed so that its width is larger than the diameter of the shaft portion 41 of the flange collar 4. In addition, as for the attachment part 11, the both sides in which the extraction hole 11h of the side wall 11e was formed become the contact surface 11k with which the plate nut 2 contact | abuts. Therefore, the plate nut 2 stops at the contact surface 11k without penetrating.

  In addition, the attachment portion 11 is formed with a rectangular groove portion 11f in a plan view so as to divide the bottom wall 11a in the center portion of the bottom wall 11a. The groove 11f is for preventing the tip of the screw 7 screwed into the plate nut 2 mounted in the mounting hole 11g from coming into contact with the bottom wall 11a.

In the above-described embodiments, the dimensions of the width of the root portion and the tip portion of the protrusion 2b, 2c are the same in x ₁ (see FIG. 2). For this reason, the plate nut 2 is formed in a cross shape in plan view. However, the shape of the plate nut 2 is not limited to this. For example, the protrusions 2b and 2c are chamfered, the width of the tip portion is made smaller than the width of the root of the protrusions 2b and 2c, and the shape of the protrusions 2b and 2c is viewed in plan view. By making it semicircular, the plate nut 2 may be formed in a substantially cross shape in plan view.

  Moreover, in 1st Embodiment, the case where the sheet metal component 3 was a horizontal plate-shaped member was assumed. However, the panel fixing structure A can also be applied when the cover 1 is installed on the inclined sheet metal part 3. In this case, what is necessary is just to make it the structure which attaches the plate nut 2 to the attaching part 11 inclining. The same applies to the panel fixing structure B according to the second embodiment. Thereby, it is possible to fix various covers (decorative panels) of the automatic transaction apparatus to the sheet metal frame. An automatic transaction apparatus 1000 shown in FIG. 9 shows a state in which a front cover (decorative panel) is fixed to a sheet metal frame (not shown) using the attachment portion 11.
