Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-member mounting structure, and more particularly, an object of the present invention is to provide a two-member mounting structure that can securely fix two members.

Generally, as a structure for fixing two members without using screws, etc., a locking part is provided in the main body part to lock the locked member in the attached state so that the locked member does not come off. There is a structure in which a locking part is inserted into the locking member to fix the locked member to the main body member. However, in the conventional mounting structure, only the locking part locks the locked member, and no member is provided to absorb dimensional errors or play in installation between the two members. There is a drawback that the screws cannot be securely fixed due to looseness between them, and therefore screws must be used for fixing in places where high-precision mounting is required.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

FIG. 1 is a plan view of a tape storage case mounting device that supports a cassette holder assembled using the two-member mounting structure of the present invention.

In FIG. 1, a cassette holder 1 has side plates (main body members) 2a and 2b on both sides, a horizontal member (locked member) 3 that horizontally spans the upper part between the side plates 2a and 2b, and a side plate 2.
It consists of a cassette support plate 4 that horizontally spans the lower part between a and 2b. Furthermore, the cassette holder 1 is attached to the horizontal member 3.
When a tape storage case 6 is inserted into this space 5, it is driven to a predetermined mounting position of the recording/reproducing apparatus.

As shown enlarged in FIGS. 2 and 3, the side plate 2
A and 2b are provided with a two-member attachment structure 7 for fixing the side plates 2a and 2b and the horizontal member 3. Incidentally, since the side plate 2a and the side plate 2b are provided with the mounting structure 7 having the same configuration, only the side plate 2a will be explained, and the explanation of the side plate 2b will be omitted.

There are two oval openings 8A at the top of the side plate 2a.
8B is perforated in the thickness direction. opening 8

is formed. The elastic deformation portions 9A and 9B have semicircular projections 9A- ₁ and 9B- ₁ on the upper center surface. A locking portion 10 is provided on the outer surface of the side plate 2a. The locking part 10 has a circular protrusion 10A at the tip.
and an inclined portion 10B, and an inverted U-shaped hole 11 around the periphery.
is provided and is integrally connected to the side plate 2a at the bottom. Reference numeral 12 denotes a clamping portion, which is spaced apart from the clamping surface 13 by a predetermined dimension to form a space 14 .

The U-shaped horizontal member 3 attached to the upper part of the side plate 2a has locked portions 3A on both sides. Locked part 3
A locking hole 3B into which the protrusion 10A of the locking portion 10 is inserted is bored in A.

When attaching the horizontal member 3 to the side plate 1, apply the locked part 3A of the horizontal member 3 to the space 14 between the clamping part 12 and the clamping surface 13 of the side plate 1, and then attach the horizontal member 3 in the direction of the arrow.
X Press in _one direction. The locked portion 3A is the inclined portion 10
B is pressed to bend the locking portion 10 in the direction of arrow A, and the locking portion 10 is inserted into the space 14. Further, the lower surface 3c of the horizontal member 3 is formed by the projections 9A- ₁ of the elastically deformable portions 9A, 9B,
Contact with 9B- ₁ .

Further, when the horizontal member 3 is pressed in the direction of arrow _X1 ,
The lower surface 3c of the horizontal member 3 presses the protrusions 9A- ₁ , 9B- ₁ into the openings 8A, 8B, and makes the elastically deformable portions 9A, 9B elastic by the protruding dimensions of the protrusions 9A- ₁ , 9B- ₁ . Transform. Therefore, the locked portion 3A of the horizontal member 3 moves further in the direction of arrow _X1 by the length of the projections 9A- ₁ and 9B- ₁ . In the horizontal member 3, the locking hole 3B of the locked portion 3A is the locking portion 1.
0, and engages with the protrusion 10A to complete attachment to the side plate 2a.

Therefore, the locking portion 10 clicks into the protrusion 10A.
is inserted into the locking hole 3B to return to the original upright state, and the horizontal member 3 is locked while the elastically deformable portions 9A and 9B are elastically deformed. The protrusions 9A- ₁ and 9B- ₁ deform the horizontal member 3 due to the elastic force of the elastic deformation parts 9A and 9B.
Arrow X to leave is energized in _two directions. Therefore, the horizontal member 3 is energized by the elastic force of the elastic deformation parts 9A and 9B, and is restricted from disengaging in the direction of arrow _X2 by the protrusion 10A of the locking part 10, and is fixed to the side plate 2a. Ru. The elastic deformation parts 9A and 9B are elastically deformed to form arrows necessary for assembling the side plate 2a and the horizontal member 3.
To absorb play and dimensional errors in the X ₁ and X ₂ directions,
The side plate 2a and the horizontal member 3 are fixed without wobbling. Further, in the direction of arrow Z, it is held between a locking part 10 and a holding part 12. Therefore, it can be safely used in a cassette holder 1 that requires relatively high precision mounting. Further, since the horizontal member 3 can be securely fixed simply by pressing in the direction of arrow _X1 without using screws or the like, this is extremely advantageous in improving the efficiency of the assembly process.

In the above description, the shapes of the protrusions 9A- ₁ and 9B- ₁ have been described as semicircular, but the shape is not limited to this, and of course may be triangular, quadrilateral, or trapezoidal, for example. In addition, the mounting structure of these two parts is made of synthetic resin,
Any material that can be elastically deformed, such as sheet metal, is fine.
It can be used not only at the cassette holder attachment point but also at any attachment point.

As mentioned above, the two-member mounting structure of the present invention provides a projection on the main body member on the surface that is pressed by the locked member when the locked member is attached to the main body member, and a thin wall including the projection. The main body member is configured by forming an opening through the main body member in the thickness direction while leaving an elastic deformation portion, and further providing a locking portion that locks the locked member in the attached state so that the locked member does not come off. When the locking member is attached to the main body member by pressing the protrusion and elastically deforming the elastically deformable portion, the elastic force of the elastically deformable portion urges the locked member in the detachment direction. It can be attached to the main body member without wobbling by simply pressing in the mounting direction on the member.
Furthermore, both parts can be securely fixed without using screws, etc., and can therefore be used in installation locations that require high-precision installation, which conventionally required screws, and can be assembled by reducing the number of parts. It also has the advantage of being able to rationalize the process, and since the main body member can be made of any material that can be elastically deformed, it can be used in a wide range of fields without limiting the field of use.
