DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring-shaped clip with a tightening lever for holding and fixing a hose or the like without tools.

[0002]

2. Description of the Related Art Conventionally, the present applicant has
Patent Application No. 229409, issued on Jan. 2, 2000
A one-day patent application has been proposed.

[0003] A ring-shaped clip provided on a general market is used to hold and fix a hose so that the hose does not come off from a generally connected pipe or the like. Those which are used and tightened by a screw member to hold the hose so as not to come off are generally commercially available.

Further, a plate-shaped hose clip provided on the general market is provided with a plurality of projections and holes on a plate surface of a long plate-like member, and the hooks are engaged with each other in a corresponding manner. It is commercially available as a band-shaped hose clip which is gradually tightened and held and held by a special tool with a dedicated tool.

[0005]

One of the applications filed by the applicant of the present invention is to form both ends of a linear member with engaging portions which engage with each other and to form an approximately ring shape by engaging with each other. A twisted portion is formed at a predetermined position by twisting a part of the linear member in a hump shape or approximately 180 degrees, and protruding outward from the ring shape.

Further, the one end of the hook portion is formed as a bent hook portion so that one end of the hook portion is linear and can be bent and hooked to the hook portion of the other end. I have.

In this method, when a hose to be connected is held and fixed, the hose is tightened by a twisting portion and held in the above-mentioned ring shape. However, if the hose is tightened too strongly, the hooking portion or the bending hooking portion is deformed. Sometimes it came loose and came off.

That is, since the hooking portion or the bending hooking portion is provided in a free state so as to hook each other, the hooking portion or the bending hooking portion is generated by a tensile force generated by a strong tightening force. May be deformed and come off.

Further, in the following application, a linear member is formed into a substantially gourd shape having a small-diameter twist-back and a large-diameter hold-back. Restriction support portions are provided on both side surfaces, and hook portions for hooking the hook holes are provided at both ends of the holding return.

[0010] This is because the holding ring tightens and holds the hose on a pipe or the like by twisting the twisting back using a tool such as a thin screwdriver, for example. At this time, the holding ring rotates in the twisting direction. The holding back is regulated by the regulation supporting part so that it does not move, so that it is efficiently and easily tightened with a small force.

[0011] Further, even if it is strongly tightened, the hook portion that hooks and hooks into the hook hole is strongly held, so that it is not deformed and loosened or comes off.

[0012] However, although it can be held strong and with a small force, a tool is always required even in a simple manner, and it has not been possible to meet a demand for easy tightening by hand. In addition, the hooks at both ends of the wire member are open, and there is a risk that the wire member will come off if it is tightened extremely strongly.

[0013] The conventional ring-shaped clip is fastened and held by a screw using a linear member or a plate-shaped member. The cost is increased by the use of the screw member and cannot be used inexpensively.

In the case of a band-shaped hose clip which is commercially available on the general market and is tightened and held stepwise, the tightening is stepwise and the tightening is insufficient, so that it may come off.

Further, if the tightening is not performed with a special tool, the tightening becomes further insufficient, and the special tool requires extra cost as a tool cost.

[0016]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a metal wire member formed in a substantially ring shape as a holding member and a wire member forming the holding member. By projecting the both ends of the wire in the outer circumferential direction and providing the tightening levers at both ends, the tightening levers can be easily twisted by hand by hand and tightened by holding back, and both ends of the linear member are open. Therefore, it is possible to tighten it extremely harder than before.

In addition, insertion portions are provided near both ends of a holding band formed by bending a plate-like member into a substantially semicircular shape, and upright pieces are formed on both side surfaces of the holding band to regulate the upright pieces. Since the holding portion is positioned between the respective supporting portions and the holding portion is inserted through the respective insertion portions,
The holding and restraining portion of the holding band restricts the holding lever from moving in the twisting direction by twisting the tightening lever portion,
Since the holding return does not move in the twisting direction in a rotating manner and the fulcrum is fixed, the force at the time of twisting is smoothly applied and the tightening can be easily performed with a small force.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a ring-shaped clip with a tightening lever according to the present invention, a metal linear member is formed in a substantially ring shape, and the ring shape is retained.

Further, both ends of the linear member forming the holding member are extended and protruded in the outer peripheral direction, and a fastening lever portion is provided at each of the both ends.

With these features, the tightening lever can be easily hand-tightened by twisting and holding, and thus can be easily tightened without using a tool, and can be extremely strongly tightened.

In addition, insertion portions are provided near both ends of a holding band formed by bending a plate-like member into a substantially semicircular shape, and standing pieces are formed on both side surfaces of the holding band to regulate the standing pieces. The holding portion is located between the respective regulating and supporting portions, and the holding portion is inserted into the respective insertion portions.

Since the fulcrum is fixed, the force when twisting the tightening lever is smoothly applied to the holding and returning, and the tightening can be easily performed with a small force.

[0024]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1 of the first embodiment, reference numeral 1 denotes a ring-shaped clip with a tightening lever, and the ring-shaped clip 1 is a ring-shaped metal member. The holding member 2 formed in a shape and the holding member 2
Are provided with fastening levers 3 at both ends thereof, which protrude outward in the outer peripheral direction.

Further, the holding member 2 is extended and protrudes with both ends of the linear member intersecting in the outer circumferential direction, and in this state, the fastening levers 3 of the long plate-like member are fixed to the both ends, respectively. Provided.

Then, in the second embodiment, as shown in FIG.
Ring-shaped clip 1 with a tightening lever according to the first embodiment
In substantially the same manner as in the above, a holding band 4 formed in a substantially semicircular shape by a plate-like member is provided below the center of the holding member 2 to form a ring-shaped clip 1a with a tightening lever.

As shown in FIG. 3, the holding band 4 has insertion portions 5 and 5 cut out from one side near the both ends, respectively, and the holding band 4 is formed below the insertion portions 5 and 5 below. Standing pieces that stand on both sides of the holding band 4 in the inner circumferential direction are respectively formed, and the standing pieces are formed as regulating support portions 6.

As shown in FIG. 3, the holding member 2 is arranged so as to be regulated between the regulating support portions 6, 6 of the retaining band 4.

As another embodiment of the tightening lever 3, as shown in FIG. 4, the tightening lever 3 is formed of a linear member. The clamping lever portion 3a is formed so as to extend and project into two ring shapes arranged side by side, and is formed in a substantially heart shape on the front.

The two side-by-side rings are welded at a portion where they are in contact with each other, and both ends are welded to form a tightening lever portion 3a such that both ends are also ring-shaped.

That is, instead of using two separate rings, they are made to function integrally, so that the tightening lever 3a
When the tightening force is as in the case of two rings,
Dispersion by elasticity can be prevented, and the tightening force can be transmitted effectively, similarly to the above-described tightening lever portion 3.

When using the ring-shaped clip 1 with the tightening lever of the first embodiment, as shown in FIG. 5, the ring-shaped clip 1 is previously held near the end of the pipe 7 such as a rubber hose. Return 2 is loosely fitted.

Then, a pipe 7 such as a rubber hose is fitted and connected to a pipe 8 to be connected, and the above-mentioned ring-shaped clip 1 is arranged at a predetermined position of the connection portion, and as shown in FIG. Then, the tightening lever 3 is twisted and rotated in one direction.

That is, by twisting the tightening lever 3, the holding member 2 is reduced to a small size.
To be firmly held and fixed to a pipe 8 to which a pipe 7 such as a rubber hose is connected.

At this time, the holding member 2 formed of the linear member
Are fixed to the tightening lever 3 so that
Even if it is tightened extremely strongly, there is no locking part as in the prior art, so that it does not come off.

When the ring-shaped clip 1a with a tightening lever of the second embodiment is used, it is used in substantially the same manner as in the first embodiment. Is restrained from rotating in the twisting direction by the regulating support portions 6, 6 of the holding band 4, and by stopping the movement of the holding return 2, the fulcrum at the time of twisting is fixed, and therefore, when the tightening lever portion 3 is twisted. The force is applied smoothly and can be easily twisted and tightened with small force.

It is to be noted that, although both ends of the holding member 2 formed of the linear member intersect and protrude outward in the outer peripheral direction, the holding member 2 is attached to the tightening lever 3 without intersecting, and the tightening lever 3 is twisted. It is also possible to tighten and hold the pipe 7 with the holding return 2, but it is not shown.

In the second embodiment, the holding band 4 is disposed on the outer peripheral side of the holding member 2. The relationship is reversed. Although some effect can be obtained even if it is provided on the opposite side correspondingly, it is not shown.

[0039]

The present invention is embodied in the form described above. In particular, the metal wire member is formed into a substantially ring shape to be a holding member, and both ends of the holding member are formed. Since the part is extended and protruded in the outer peripheral direction, and a tightening lever part is provided at both ends,

The tightening lever can be easily twisted by hand and tightened by holding and returning, so that a pipe such as a rubber hose can be easily tightened and held without using a tool. It can be manufactured and provided at a low cost without a hook portion and without detachment.

Further, insertion portions are provided near both ends of a holding band formed by bending a plate-like member into a substantially semicircular shape, and standing pieces are formed on both side surfaces of the holding band to regulate the standing pieces. Since the holding portion is positioned between the respective supporting portions and the holding portion is inserted through the respective insertion portions,

The force when twisting the tightening lever portion is smoothly applied to the holding and returning, and the hose can be easily tightened to a pipe or the like with a small force, and can be strongly held and fixed, thereby providing a significant effect in practical use.
