Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a spring clip having two adjacent clamping portions on the same plane, and in particular to a spring clip that locks a rod-shaped body to another object by a spring action. About the spring clip you get.

<Prior art> For example, as a clip for holding two rod-shaped bodies of different diameters at a certain distance from each other,
As disclosed in Japanese Patent No. 27326, a rectangular plate piece is bent into a shape having a first clamping part having an open part and a second clamping part which is generally closed, A spring clip in which an E-shaped slit is provided at the top of the second clamping part, and a tongue piece opened by the slit is bent inward to form a circular notch with a somewhat smaller diameter inside the second clamping part. is proposed. According to this, when the rod-shaped bodies having different diameters are inserted into both the clamping parts, the clamping parts are brought into tension with each other, so that the two rod-shaped bodies can be held relatively reliably.

However, this conventional example requires different processing steps of slitting and bending, which is not only cumbersome to manufacture, but also because the rod-shaped body is held by the notched circular part in the second holding part. The clamping force is not necessarily strong. In addition, unless an opening larger than the diameter of the circular notch is provided, both rods must be inserted from the axial direction, and in order to insert one rod from the opening, the two rods must be attached. There is also the disadvantage that the order is limited and the installation work is troublesome.

<Problems to be Solved by the Invention> In view of the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide a spring that is easy to manufacture, has excellent installation workability, and has relatively few restrictions on the object to be held.・The purpose is to provide clips.

<Means for Solving the Problems> According to the present invention, such an object is a spring clip having two adjacent holding portions on the same plane, which constitute the spring clip. A first clamping portion is defined by a first surface of the member by bending an intermediate portion of the member, and the first end of the member surrounds the second end and faces each other. Achieved by providing a spring clip characterized in that a second clamping portion is defined by a first surface of the first end and a second surface of the second end. be done.

<Function> By bending the member in this way, two clamping portions are obtained, so it can be manufactured by only bending. Furthermore, when the object to be held is attached to one of the clamping parts, the other clamping part is compressed, and the clamping force of both clamping parts is strong, and the clamping action is reliable. Furthermore, since the size of both clamping parts can be set arbitrarily,
This not only has a wide range of uses, but also allows two objects to be held to be inserted into the holding part laterally from the open part.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A spring clip according to this embodiment is shown in FIGS. 1-3. In Fig. 1, one end of a thin strip material made of highly elastic metal or synthetic resin is bent approximately at right angles at a straight section 1 of an appropriate length, and the bent section 2 is used as a starting point. Draw approximately 3/4 circle to reach the second bending part 4, and then move to the small diameter part 3.
to compose. Next, starting from this second bent part 4, the strip material is again bent radially outward in a substantially circular shape to form a large diameter part 5, and the extending part 6 on the free end side is bent as described above. It is made to extend toward the inside of the circular arc of the small diameter portion 3. Furthermore, the terminal end of the extending portion 6 forms a semicircular portion 7 that curves in an arc toward the straight portion 1 side.

In this way, the outer surface of the extending portion 6 and the straight portion 1
A guide portion 8 is provided between the inner surface of the small diameter portion 3 and a small clamping portion 9 is provided between the inner surface of the small diameter portion 3 and the outer surface of the semicircular portion 7.
Large clamping portions 10 are defined inside the large diameter portions 5, respectively.

Next, regarding the installation procedure of the rod-shaped body in this example,
This will be explained with reference to FIG.

First, when the large-diameter rod-shaped body 31 is inserted into the large-diameter portion 10 from the axial direction, a force is applied to the large-diameter portion 5 in the direction of expanding its diameter, and the large-diameter portion 10 is expanded. A force is applied to the circular portion 7 in the direction of compressing the small clamping portion 9 .

Next, by pushing the small-diameter rod-shaped body 32 into the small clamping part 9 from the guide part 8 along the outer surface of the extending part 6 or the inner surface of the straight part 1, both clamping parts are strongly pressed against each other. Two rod-shaped bodies 31, 3
2 is reliably maintained. In this way, the object to be held can be inserted into the small clamping part 9 by moving in the radial direction from the guide part 8, so even a soft object, such as an electric wire, can be easily attached to the small clamping part 9. Therefore, there is no restriction on the order in which the two objects to be held are attached.

A modified embodiment according to the present invention is shown in FIGS. 4 and 5.

FIG. 4 shows that the small clamping part 9 in the first embodiment is formed relatively flat, and a flat object 42 is placed inside the small clamping part 9.
The small diameter portion 3 of the first embodiment is made into an oval shape, and the end portion of the extension portion 6 is formed into a linear shape without providing a semicircular portion 7. It has been done. according to this,
For example, it is suitable for use in securing a rod-shaped body 41 such as a pencil to the cover of a file or the like.

In FIG. 5, the positional relationship between the small diameter part and the large diameter part is reversed from that of the first embodiment. In this case, both objects to be held can be inserted into both the holding parts from the lateral direction, that is, from the radial direction.

In the above embodiment, the spring clip is made of a thin strip-like material, but it may also be made of a wire-like material, and both clamping parts may have the same diameter.

<Effects of the Invention> As described above, according to the present invention, the spring clip can be manufactured by simply bending the material constituting it continuously, so it can be easily mass-produced and has a great effect on cost reduction. There is. Further, while one is inserted from the axial direction, the other can be fitted more easily than the guide part, and the installation order can be selected, improving work efficiency.

Furthermore, as shown in the modified embodiment, it is possible to make it suitable for attachment to a flat plate, to make it possible to insert both objects to be held from the radial direction, and to freely set the dimensions of both holding parts. It is also highly versatile.
