Abstract

The present invention provides a staple that prevents a leg portion from being pulled out by striking a heat insulating cover that covers a pipe such as a water pipe or a hot water supply pipe and a pipe such as a heat transfer pipe for air conditioning. . A staple 1 according to the present invention is formed by forming a single steel wire into a gate shape, and forming a horizontal portion 2 in the horizontal direction and left and right leg portions 3 and 3 integrally hanging from both ends of the horizontal portion 2. It consists of. Notches 4, 4 are provided in a direction orthogonal to the axial direction of the left and right legs 3, 3 just below the connecting part between the horizontal part 2 and the left and right legs 3, 3. Further, the front end portions of the left and right leg portions 3 and 3 are cut obliquely to form inclined surfaces 5 and 5. [Selection] Figure 1

Description

  The present invention relates to a staple that is driven by striking a heat insulating cover that externally covers pipes such as water pipes and hot water supply pipes and pipes such as heat medium supply pipes for air conditioning.

A staple is known in which when a sheet metal is driven by a staple driving machine, a leg portion penetrating the sheet metal is automatically bent inward or outward to fasten the sheet metal (see Patent Document 1).
This known technique is a staple formed by forming a single steel wire into a gate shape, bending the center of the horizontal top portion connecting the upper portions of the left and right legs downward to form an M shape, Inclined inward in the middle of the upper and lower sides to reduce the interval, molded into a shape where the lower part was shifted horizontally inward with respect to the upper part, and the outer surface of the tip of the left and right leg parts was cut obliquely to form an inclined surface It is a staple for sheet metal.

In addition, there are known staples for fixing a lath net or the like, and both the leg portions thereof can be curved in the wood, and the buckling does not occur at both ends of the top portion, and the staple driving device is known ( (See Patent Document 2).
In this known technique, in a U-shaped staple having a pair of leg portions bent at right angles to both ends of a horizontal top portion, curved portions that are symmetrically formed at the distal ends of the pair of leg portions are provided. The pair of curved portions are staples positioned within the extension lines of the outer surface and the inner surface of the rear end portion of the leg portion.

Furthermore, a staple having a strong coupling force that does not come out on the surface of the decorative panel even when it is driven at right angles without requiring skill is known (see Patent Document 3).
In this known technique, the tip of each leg is tapered so that the tip is tapered by a flat slope toward the leading edge, and the leading edge formed by the flat slope is the center line of the thickness of each leg. The staples are positioned so as to be offset from each other, and incisions for inducing bending are provided at regular intervals in the axial direction in the leg portions other than the tip portion.

  An object of the present invention is to provide a staple that prevents a leg portion that has been driven by striking a heat insulating cover covering a pipe such as a water pipe or a hot water supply pipe and a pipe such as a heat transfer pipe for air conditioning. And

The staple of the present invention is a staple formed by forming a single steel wire into a gate shape, and includes a horizontal portion connecting upper portions of the left and right legs, and left and right legs integrally suspended from both ends of the horizontal portion. A notch provided in a direction perpendicular to the axial direction of the left and right leg portions directly below the connecting portion between the horizontal portion and the left and right leg portions, and an outer surface of the distal end portion of the left and right leg portions obliquely It is cut into an inclined surface.
The notch is at least as thick as an aluminum glass cloth decorative base paper of a heat insulating cover that externally covers a pipe such as a water pipe or a hot water supply pipe and a pipe such as a heat transfer pipe for air conditioning.

  In the present invention, a notch is provided in the direction perpendicular to the axial direction of the left and right leg portions directly below the connecting portion between the horizontal portion of the staple and the left and right leg portions. It is possible to prevent the left and right leg portions of the staples driven by striking the heat insulating cover covering the pipes such as the heat medium feeding pipe from being detached.

It is a front view of the staple of this invention. It is a perspective view which shows the coupling body of the staple of this invention. It is sectional drawing which shows the operation | movement which drives the staple of this invention in a heat insulation cover with a stapler. It is sectional drawing which shows the state which driven the staple of this invention in the heat insulation cover.

One embodiment of the staple of the present invention will be described below with reference to the accompanying drawings.
As shown in the front view of FIG. 1, the staple 1 of the present invention is formed by forming a single steel wire into a gate shape and horizontally suspending the horizontal portion 2 and the left and right sides of the horizontal portion 2 integrally. Leg portions 3 and 3.
Notches 4, 4 are provided in a direction perpendicular to the axial direction of the left and right legs 3, 3 immediately below the connecting portion between the horizontal part 2 and the left and right legs 3, 3.
Furthermore, the front end portions of the left and right leg portions 3 and 3 are cut obliquely to form inclined surfaces 5 and 5.

  As shown in FIG. 2, the staple 1 of the present invention is provided in a form in which a large number of staples are bonded and connected in the same manner as a conventional staple, and is used by being loaded into a staple magazine of a manual stapling machine.

Next, the operation of stapling according to the present invention will be described below with reference to the accompanying drawings.
A large number of connected staples 1 shown in FIG. 2 are loaded into a staple magazine of a manual stapling machine 6 and, as shown in FIG. 3, a heat insulating material 8 and aluminum for covering a pipe 7 such as a water pipe or a hot water supply pipe. The staple 1 is driven by the staple driving machine 6 at the joint portion such as the glass cloth decorative base paper 9.
As shown in the sectional view of FIG. 4, the driven staple 1 is formed by inclining the front end of the leg 3 to form the inclined surfaces 5 and 5, so that the legs 3 and 3 are outward. Invades the insulation 8 while spreading.
When the staple 1 is completely driven, the notches 4 and 4 in FIG. 4 are fitted to the aluminum glass cloth decorative base paper 9 and 9, so that even when the horizontal portion 2 is lifted to remove the staple 1, for example, Since the notches 4 and 4 are in the fitted state with the aluminum glass cloth decorative base paper 9 and 9, they cannot be easily removed.
Therefore, the cutouts 4 and 4 are fitted with the aluminum glass cloth decorative base paper 9 and 9, so that the staple 1 can be prevented from coming off at the joint between the heat insulating material 8 and the aluminum glass cloth decorative base paper 9.
