Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for bumpers and hooks for hanging articles, or metal fittings used for various other purposes.

In other words, the present invention aims to provide a structure for mounting the metal fittings that is easy to install in the mounting groove and provides a stable mounting condition, and its features include a narrow inlet opening and a wide A metal fitting to be attached to a mounting groove consisting of a structure has a head having a diameter larger than that in the opening of the mounting groove, and is formed on the back surface of the head so as to fit into the opening of the mounting groove. a pedestal having opposing sides; and a constriction formed following the pedestal and having a small enough diameter and sufficient length to allow the head and pedestal to pass through the opening of the mounting groove and into the groove. It consists of a metal fitting main body having a diameter shaft portion and a male threaded portion formed following the reduced diameter shaft portion, and a nut that is threadedly engaged with the male threaded portion, and the head and base portion of the metal fitting body are connected to the opening of the mounting groove. The fitting is now installed by inserting the nut into the groove, fitting the base into the entrance opening of the mounting groove, and tightening the nut toward the outer wall of the groove. .

In order to facilitate insertion of the head and part 1, the head should have a shallow spherical shape, the base should also have a shape as low as possible, and the reduced diameter shaft should have a notch on one side of the circular cross section coaxial with the head. It is preferable to create a structure that is eccentric to the head by, for example, having a semicircular cross section.

Further, when the metal fitting is a hook for hanging an article, it is preferable that the nut can be inserted from the head side, and for this purpose, it is preferable that the male threaded portion has a larger diameter than the head.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The metal fitting body, that is, the hook 1 in this embodiment has a hook portion 1a and a male threaded portion 1b formed at the root of the hook portion 1a. A reduced diameter shaft portion 1 extends from the end.
C is formed, and a base portion 1d and a head portion 1e are formed at the end of the diameter-reduced shaft portion 1C.

The head portion 1e has a shallow spherical shape and is formed coaxially with the threaded portion 1b, and the base portion 1d has a square planar shape as shown in FIG.

The reduced diameter shaft portion 1C has an eccentric structure in which one side of a circular cross section coaxial with the head is cut out to form a semicircular cross section.

The nut 2 has a tapped hole 2a that engages with the male threaded portion 1b of the metal fitting body 1, has a truncated conical shape as a whole, and has a seat surface 1b at the large diameter end.
is formed.

The mounting groove member 3 has a narrow artificial opening 3a and a wide groove 3.
The fitting body 1 can be inserted into the groove 3b by passing the head 1e and the base 1d through the entrance opening 3a, as shown in FIG. 3a. Can be done.

Next, as shown in FIG. 3, the opposing side surfaces of the base portion 1d are fitted into the inlet openings 3a of the mounting grooves, and the nut 2 is tightened so that its seat surface 2b contacts the outer wall surface of the mounting groove 3. This completes the installation of the metal fittings.

In this case, since the threaded portion 1b has a larger diameter than the head 1e, the nut 2 can be inserted in advance from the head 1e side.

Since the opposing side surfaces of the base portion 1d, that is, the side surfaces located at the upper and lower sides in Fig. 3, are configured to open into the inlet opening 3a of the mounting groove, when tightening the nut, the metal fitting does not wobble, and the nut can be tightened. The tightening operation is facilitated, and the positioning of the fitting head 1e relative to the inlet opening 3a is also ensured.

Providing the reduced diameter part 1C reduces the strength of the metal fitting at the attachment part, but this can be done by adjusting the dimensions of the male threaded part 1b, reduced diameter part 1c, base part 1d, and head part 1e appropriately depending on the purpose of use of the metal fitting. By determining this, it can be made sufficiently strong and can be solved in terms of design.

As explained above, according to the present invention, the operation is easy and
A metal fitting mounting structure is provided that allows a reliable mounting state to be obtained.

Claims (1)

[Scope of utility model registration request] It consists of a mounting groove consisting of a narrow inlet opening and a wide groove, and a metal fitting that is attached to this mounting groove.
A head portion having a larger diameter than the inside of the opening of the mounting groove, a pedestal portion formed on the back surface of the head portion, a diameter-reduced shaft portion formed subsequent to the pedestal portion, and a diameter-reduced shaft portion formed subsequent to the diameter-reduced shaft portion. It consists of a metal fitting main body having a male threaded part having a minimum thread diameter larger than the diameter of the head, and a nut that threadably engages with the male threaded part, and the base part has parallel threaded parts formed at diametrically opposite positions. the width of the platform, defined as the distance between the two sides, is smaller than the width of the artificial opening so that the platform can fit into the entrance opening of the mounting groove; The diameter-reducing shaft portion is arranged to be biased toward one side with respect to the base, and on the other side, the head and base of the metal fitting body are passed through the opening of the mounting groove into the groove. The metal fitting mounting structure is such that the metal fitting is then mounted by fitting the two side surfaces of the base part into the entrance openings of the mounting groove and tightening the nut toward the outer wall surface of the mounting groove.
