Description

Rope buckle and rope fastening device

The present invention relates to a rope fastener constructed by fastening a cord that is inserted with a predetermined fastening force, and a rope fastening device comprising the rope fastener.

There is a rope binding device in which a rope holding body formed by arranging a rope engaging portion projecting from a base portion between two tubular rope insertion passages is provided at two locations (see Patent Document 1).

In the rope bale of Patent Document 1, the rope is a rope which is placed between the two rope insertion passages so that the projecting end is located above the rope insertion passage in a state where the ropes are respectively inserted through the two ropes. The engaging portion is engaged with the rope. Therefore, it is quite difficult to install the rope bale on the rope at the beginning. Further, in Patent Document 1, it is also disclosed that one or both of the rope engagement portions are provided with a slit that communicates with the side of the rope insertion passage, and the slit is formed in a C-shaped cross section. If such a slit is provided, it is easy to use the slit to introduce the rope into the rope insertion passage. However, in the structure of Patent Document 1, when a force in a direction intersecting the longitudinal direction of the rope acts on the rope held by the rope insertion passage, there is a possibility that the rope is released from the slit.

The horizontal bar structure 2 on the lower right side of the center axis y and the horizontal bar structure 2 on the lower left side function as the exit bar 2b.

Moreover, in the example shown in Fig. 22, the rope fastening device R and the handle member H constitute a rope fastening device. The handle member H is provided with the insertion portion Ha of the aforementioned rope W, and is attached to the rope W by passing the rope W through the insertion portion Ha. In the example shown in the figure, the handle member H has a cylindrical shape in which both ends of the cylinder are open, and has two through holes Hb and Hb at the side of the cylinder, and becomes a through hole Hb by the two portions.

Between the left ends. In the example shown in the figure, the wide side surface portion Hd of the handle member H does not enter between the adjacent horizontal bar constituent bodies 2, but the narrow side surface portion Hc enters.

In the rope fastening device constructed in this manner, by grasping the handle member H and performing an operation of pulling it, typically, the rope fastener R is grasped with one hand, and the handle is grasped with the other hand. Member H and performing an operation of pulling the handle member H, whereby the rope W can be taken from the rope The buckle R is pulled out and the fastening position of the rope fastener R with respect to the rope W is adjusted (Figs. 22 to 23).

In the example shown in the figure, between the adjacent horizontal bar constituent bodies 2 and 2, the outer edge portion 15a of the base portion 15 and the outer edge portion 17a surrounding the connecting portion 17 are formed in a concave shape. On the other hand, the narrow side surface portion Hc of the handle member H is formed in a convex shape that fits concavely with the outer edge portions 15a and 17a. In the example shown in the figure, the ropes R and the handles are formed in a state in which the ropes W between the bodies 2 and 2 are formed by the adjacent horizontal bars from the lower side in which the handle member H is attached to the 22nd drawing. In the case where the member H is in close contact, at least a part of the handle member H, in the example shown in the figure, is the narrow side surface portion Hc, and is housed in a good appearance as a side located on the side across the central axis y. The horizontal bar structure 2 that functions as the exit bar 2b and the bar structure 2 that functions as the outlet bar 2b located on the other side of the center axis y (FIG. 22).

Although the drawing is omitted, the handle member H may be attached to, for example, the rope W between the bodies 2 and 2, which is vertically adjacent to each other across the right side of the central axis y in FIG. 22, or may be attached thereto. In Fig. 22, the horizontally adjacent horizontal bars on the left side of the central axis y constitute a rope W between the bodies 2 and 2. In this case, when the cord fastener R is brought into close contact with the handle member H, at least a part of the handle member H, in the example shown in the figure, is the narrow side portion Hc, and can be accommodated as the entrance. The horizontal bar constituting body 2 that functions as the horizontal bar 2a and the horizontal bar constituting body 2 that functions as the exit horizontal bar 2b.

Further, the present invention is not limited to the above described The embodiment, of course, also encompasses all embodiments that achieve the objectives of the invention.
