Description

There is an application for exception to loss of novelty

The invention of the present application is applied to load-fastening belts such as lashing belts, ropes, and wire ropes for attachment objects made of ferromagnetic materials such as iron, nickel, and cobalt, such as cargo beds and gates of trucks. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic mounting fixture for detachably mounting an object to be mounted such as a scale with a magnet, and relates to a structure for attaching a fastener for locking the mounting target to the magnetic mounting fixture.

The mounting structure of the fastener in the magnetic attachment according to the invention of the present application is for attaching the fastener to the magnetic attachment that attaches the attachment object to the attachment object formed of a ferromagnetic material with a magnet. Although it can be widely used for a wide range of applications, in this application, the loading platform and gates of a freight vehicle are used as the mounting objects, and the case of mounting long objects for tightening cargo such as belts, ropes, and wire ropes as the mounting object is taken as an example. to explain.

In general, when a load is loaded onto a loading platform of a freight vehicle and transported, the above-described Various long bodies for securing cargo are fixed to the cargo bed, stretched over the cargo, and fastened to the cargo bed. Here, in fixing the long body for securing cargo to the cargo bed, the hook member attached to the end of the long body for securing cargo is attached to the outer edge of the cargo bed or the outside surface of the gate. Generally, a method of hooking on various locking tools such as a ring and a method of locking by tying the ends of the elongated body for cargo fastening to the locking tool are commonly used.

However, the following problems have arisen in the general method for fixing the above-described elongated body for securing cargo to the loading platform. That is, the elongated body for securing cargo can only be fixed to a cargo bed, etc., to which a locking device such as a hanging ring is attached, and even to a cargo bed, etc. to which the locking device is attached, The user cannot necessarily fix the load clamping elongated body at a desired position because the load clamping elongated body cannot be fixed at a location where the locking tool is not attached. Locking devices are often attached to the outer edge of the cargo bed or the outer surface of the gate. First, a lot of time and effort is spent on securing the cargo to the cargo bed. When the long body is locked to the locking tool, a gap is generated between the long body for securing cargo and the cargo when the height of the cargo is lower than the height of the flap of the cargo bed. There is a problem that the cargo cannot be firmly tightened, and the cargo may collapse during transportation or the cargo may fall off the loading platform.

Therefore, there has been proposed a magnetic attachment type fixture for securing a long body to the cargo bed of a truck using the magnetic attraction force of a magnet. It consists of a magnet and a belt for fixing to the side wall, a first eye hook is fixed perpendicular to the surface of the first magnet, and a first detachable clasp is connected to it, A second eyehook is similarly secured to the second magnet and is connected to a second removable clasp, the strap having a spring-loaded buckle attached to one end thereof and the first eyehook attached to the other end thereof. An adjustable magnetic cargo strap system has been proposed that consists of a clasp and a structure that tightens through a slot in the second clasp (see, for example, US Pat.

According to the magnetic attachment type load clamping long body fixture according to the prior art as described above, the load clamping long body can be fixed using only the magnetic attraction force of the magnet. In general, the cargo bed and gates of trucks are made of ferromagnetic metal such as iron. can. As a result, the above-described magnetically-attached load clamping elongate body fixing member can fix the load clamping elongate body even to a cargo bed or the like to which no locking member such as a hanging ring is attached. In addition, the long body for securing cargo can be freely fixed at a position desired by the user. In addition, it is no longer necessary to bridge the load-binding elongated body over the cargo bed, and the time and labor required for tightening the cargo on the cargo bed can be saved. Furthermore, when the height of the cargo is lower than the height of the flap of the cargo bed, for example, the magnetic attachment type load fastening elongated body fixture is magnetically attached to the bottom surface of the cargo bed or the inner surface of the flap. By locking the long body for securing cargo to a wearable long body fixture for securing cargo, the long body for securing cargo and the cargo are tightly fastened so as not to create a gap. It is possible and preferable.

By the way, in order to fix the long cargo fastening body to the loading platform only by using the magnetic attraction force of the magnet, and thereby firmly fasten the cargo, the magnet may be, for example, a neodymium magnet. It is necessary to use permanent magnets with strong magnetism, such as rare earth magnets. However, when a permanent magnet having a strong magnetic attraction force is used as the magnet, a problem arises at the same time that it becomes difficult to remove the long body fixture for fastening cargo from the cargo bed or the like.

Therefore, there is provided a fastener main body, a fastener attached to the upper surface of the fastener main body for locking the load clamping elongated body, and the load clamping elongated body fastener for magnetically attaching the fastener. A magnet attached to the lower surface of the fixture main body, an arm rotatably attached to the fixture main body via a fixed rotary shaft, and an arm attached to one end of the arm to be gripped by the user. and a roller attached to the other end of the arm through a fixed rotating shaft so as to be rotatable with respect to the magnetized surface. An elongated body fixture has been proposed (see, for example, Patent Document 2 below).

According to the magnetic attachment type long body fixture for fastening loads according to the prior art as described above, since the principle of lever is used, when the user lifts the handle that hits the point of force when removing it, the As the arm rises on the side of the handle about the fixed rotating shaft, the roller, which hits the fulcrum, rotates with respect to the magnetized surface such as the loading platform, so that the magnet hits the point of action. It is possible to pull away from the magnetized surface and remove the long body fixture for fastening a load, which is preferable.

Below, the mode of use of the magnetic attachment type fixture according to one embodiment of the invention of the present application will be described with reference to the accompanying drawings.

First, the user uses the magnetic attraction force of the magnet (A2) at a desired position on an object to be attached, which is formed of a ferromagnetic material such as iron, nickel, or cobalt, such as a cargo bed or gate of a truck. Secure the magnetic attachment (A).

Next, the user attaches the object to be attached to the magnetic fixture (A) according to the object to be attached, such as a load fastening belt such as a lashing belt, or a long load fastening body such as a rope or wire rope. A fastener (B) having a form suitable for fastening is appropriately selected. For example, if the object to be attached is a rope or wire rope, a fastener having a ring-shaped locking portion (B2) as shown in FIG. When the object to be attached is a cargo fastening belt, a hook-shaped engaging portion as shown in FIG. Select the fastener with (B2). Then, as shown in FIGS. 4 and 5, the user engages and attaches the mounting portion (B2) to the mounting portion (A1), and attaches the fastener (B) to the magnetic mounting fixture (A). Installing. Specifically, the mounting part (A1) is mounted by engaging the screw cut on the outer peripheral surface of the mounting part (A1) with the screw cut on the inner peripheral surface of the hole of the mounting part (B1). Then, the mounting portion (B1) is rotated and advanced, and the mounting portion (B1) is screwed to the mounting portion (A1). A fastener may be attached to the magnetic attachment type fixture (A) before fixing the magnetic attachment type fixture (A) to the object to be attached.

Here, depending on various circumstances such as the shape of the cargo, the condition of the cargo bed, and the loading condition of the cargo on the cargo bed, there is a suitable direction for locking the object to be attached to the fastener (B). For example, when the object to be attached is a cargo fastening belt, the opening of the hook on the object to be attached and the hook on the side of the fastener may be separated from each other when the hook member attached to the end of the belt is engaged and hooked. If the openings of the fasteners are positioned so as to face each other, the attachment object may be unintentionally removed from the fastener by the user.
