Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a spring clip having two clamping parts adjacent to each other on the same plane. About the spring clip you get.

<Prior art> As a clip for holding two rod-shaped bodies of different diameters at a certain distance from each other, for example, as disclosed in Japanese Utility Model Publication No. 52-27326, a strip-shaped plate piece is used with an open part. The first clamping part is curved into a Daruma shape so as to have a generally closed second clamping part, and an engineered slit is provided at the top of the second clamping part, and the second clamping part is opened by the slit. Spring clips have been proposed in which the tongues are bent inward to form a somewhat smaller internal notch in the second jaw. According to this, when the rod-shaped bodies having different diameters are inserted into both the clamping parts, the two 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, slitting and bending, and is not only cumbersome to manufacture, but also because the rod-shaped body is held inside the notch in the second clamping part. The clamping force is not necessarily strong. Also, unless an opening larger than the diameter of the inside of the notch is provided, both rods must be inserted from the axial direction, and in order to insert one rod from the opening, the order in which the two rods are installed must be changed. There is also the disadvantage that the installation work is troublesome.

<Problems to be Solved by the Invention> In view of the drawbacks of the prior art, the main objectives of the present invention are to provide easy manufacturing, excellent installation workability, and relatively less restrictive conditions for the object to be held. The purpose is to provide fewer spring clips.

<Means for Solving the Problems> According to the present invention, an object of the present invention is to provide a spring clip having two clamping portions adjacent to each other on the same plane. an intermediate portion of the member is curved so that a first side of the member defines a first gripping portion, and a first end of the member surrounds a second end;
and a second clamping portion is defined by a first surface of the first end and a second surface of the second end that are moon-shaped with respect to each other. This is achieved by providing

<Function> By bending the member in this way, a clamping part can be obtained, so it can be manufactured by only bending. Further, when the object to be held is attached to one of the clamping parts, the other clamping part is tightened, 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 arbitrarily set, it is not only versatile, but also allows two objects to be held to be inserted sideways into the clamping parts 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-shaped material made of highly elastic metal or synthetic resin is bent approximately at right angles at a straight section 1 of suitable length, and a second section is made from the bent section 2 as a starting point. The small diameter portion 3 is curved by drawing an approximately 3/4 circle that reaches the second bent portion 4. Next, this second bent part 4
Starting from the point, the strip material is again bent radially outward in a substantially circular shape to form the large diameter section 5, and the extending section 6 on the free end side is extended into the arc of the small diameter section 3. Let it come out. 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 guide portion 8 is provided between the outer surface of the extending portion 6 and the inner surface of the straight portion 1, and the guide portion 8 is provided between the inner surface of the small diameter portion 3 and the semicircular portion 7.
A small gripping portion 9 is defined between the outer surfaces of the holder and a large gripping portion 10 is defined inside the large diameter portion 5.

Next, the procedure for attaching the rod-shaped body to this embodiment will be explained with reference to FIG. 3 as well.

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, so that A force is applied to the circular portion 7 in the direction of tightening the small clamp holder 9.

Next, by pushing the small-diameter rod-shaped body 32 from the guide part 8 into the small clamp 4 part 9 along the outer surface of the extending part 6 or the inner surface of the straight part 1, both clamp parts are tightly pressed against each other. The two rod-like bodies 31 and 32 are then fitted together and are securely held. As described above, since the object to be held can be inserted into the small clamp holding part 9 by moving in the radial direction from the guide part 8, the small clamp holding part 9
For example, even a soft object such as an electric wire can be easily attached to the inside, and there are no restrictions on the order in which the dual wave holders are attached.

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

FIG. 4 shows the small clamp holder 9 in the first embodiment formed relatively flat so as to be suitable for holding a flat object 42 in the small clamp holder 9. The small diameter portion 3 is formed into an oval shape, and the terminal end portion of the extension portion 6 is formed into a linear shape without providing a semicircular portion 7. According to this, the rod-shaped body 41, such as a pencil, is suitable for use in securing 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 the insured holidays 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 material, but it may also be made of a button metal material, and both gripping portions 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 continuously bending the material constituting the spring clip, and therefore mass production is easily possible. effective. Also, one side is inserted from the axial direction,
The other part can be fitted more easily than the guide part, and can be installed in any order, improving work efficiency.

Furthermore, as shown in the modified embodiments, it can be made suitable for attachment to a flat plate, the inner sheath holding body can be inserted from the radial direction, and the dimensions of both clamping parts can be set freely. It is also highly versatile.
