Abstract

PROBLEM TO BE SOLVED: To provide a clamp capable of preventing erroneous locking in transportation and allowed to be easily locked in assembling to a vehicle and hardly detached while the structure is simple. SOLUTION: This clamp 1 is so constructed that when a heater hose HH as an object for clamping is not fitted in a main body part 2, a locking part 25 is positioned inside a turning locus of a locked part 3d to be disabled from being locked with the locked part 3d, thereby preventing erroneous locking. In assembling to the vehicle, when the heater hose HH is fitted in the main body part 2, the locking part 25 is displaced onto the turning locus of the locked part 3d to be engaged with the locked part 3, resulting in producing the effect of locking in a single operation.

The locked portion 3 is locked by one touch, and the heater hose HH is fixed. Since a relatively large force is applied to the heater hose HH when the passenger compartment is tilted up, the heater hose HH is configured so as not to come off easily once locked. With this configuration, the heater hose HH could be easily and reliably fixed.

[0003]

However, if the clamp 101 has a structure in which the clamp 101 is locked by one touch, when the clamp 101 as a part before assembly is transported, even if the clamp 101 is transported without being locked, it is not transported. In some cases, the clamp 101 is erroneously locked due to vibration at the time. Once the lock 101 is erroneously locked, the lock is not easily released for the reason described above.
Has to be unlocked, resulting in a problem that extra steps are required. Providing a mechanism for easily releasing this lock has a problem in that the structure of the clamp 101 becomes complicated and the cost of parts increases.

In order to solve the above-mentioned problems, the present invention has a simple structure, but does not cause erroneous locking during transportation.
It can be easily locked when assembled to the vehicle,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a clamp according to the present invention will be described with reference to the drawings using a clamp 1 as one embodiment. Here, FIG. 1 is a perspective view of the clamp 1 with the lid 3 opened. In FIG. 1, the direction indicated by arrow FR is defined as the front, and the direction indicated by arrow LH is defined as the left. The clamp 1 is entirely formed of a resin having elasticity, for example, PP (polypropylene), and includes a main body 2 and a lid 3.

FIG. 2 is a perspective view of the clamp 1 with the lid 3 closed. As shown in FIG. 2, when the lid 3 is closed, the entire clamp 1 in which the lid 3 is closed to the main body 2 has a shape in which two cylinders having the same inner diameter are connected, and has a substantially symmetrical shape. The inner diameter of the cylindrical portion with the lid 3 closed is formed to be equal to the inner diameter of the heater hose HH to be clamped in the present embodiment. That is, the clamp 1 can be formed in various sizes. However, when the inner diameter when the lid 3 is closed is substantially the same as the outer diameter of the object to be clamped, or when the object is soft, It is formed with a slightly smaller inner diameter.

The main body 2 shown in FIG. 1 has a substantially cylindrical first fixing portion 21 whose center is disposed in the front-rear direction, and is disposed to the left of the first fixing portion 21 and has the same length as the first fixing portion 21.

A leg portion 24 is provided below the connecting portion lower portion 23b. The first fixing portion 21 is provided at a central portion of its outer surface,
An annular rib 27 that is continuous in the circumferential direction is provided, and its strength is increased.

The connecting portion upper portion 23a and the connecting portion lower portion 23b are flat plate-like members arranged horizontally and parallel at a distance of approximately one half of the inner diameter of the first fixing portion 21. Are formed integrally. A rib 28 that is continuous from the rib 27 is formed at the center of the upper surface of the connecting portion 23a.
The second fixed part 22 is composed of a second fixed part upper part 22a and a second fixed part lower part 22b. The upper second fixing portion 22a extends from the end of the upper connecting portion 23a to substantially the top of the second fixing portion 22. Further, a lock portion 25 is formed above the second fixed portion upper portion 22a.

The lock portion 25 has a vertical portion 25a erected from the vicinity of a joint between the connecting portion upper portion 23a and the second fixed portion upper portion 22a. The horizontal portion 2 extends horizontally to the left from the upper end of the vertical portion 25a.
5b is extended. In addition, the opening 25c is
It is drilled approximately at the center of b. The tip of the horizontal portion 25b is formed with a tapered portion 25d whose lower portion is obliquely cut.

The lower connecting portion 23b is formed continuously from the first fixing portion 21, and the lower connecting portion 23b and the upper connecting portion 23a are formed.
Are provided symmetrically with respect to a plane including the center line of the first fixing portion 21 and the center line of the second fixing portion 22. Lower part 2
From the left end of 3b, the lower portion 22b of the second fixing portion is approximately 3 mm of the inner diameter of the second fixing portion 22 from the center line of the second fixing portion 22.
It extends to the left about one-half. The main body 2 is thus formed in an annular shape having an opening as a whole.

A hinge 26 is provided at the left end of the lower second fixed portion 22b. The hinge portion 26 is located below the second fixed portion 2.
2b are provided with shaft supports 26a, 26b protruding from both ends. Holes 26c, 26c are formed in the shaft support portions 26a, 26b in the front-rear direction.
26d is penetrated. The lid 3 is pivotally supported by the holes 26c and 26d.

The cover 3 is formed in a curved surface having an arc-shaped cross section.
The inner diameter is formed substantially equal to the outer diameter of the object to be clamped, and when the lid 3 is closed, the lid 3a having a cylindrical shape is provided together with the second fixing portion 22 as described above. A rotating shaft 3b is connected to one end of the lid 3a by a connecting portion 3c. Further, a locked portion 3d is provided at the other end of the lid 3a. Locked part 3d
Is protruded in a shape along the cylindrical shape with the lid 3a closed. A lock claw 3e protruding in the outer circumferential direction of the cylinder is provided at the tip end.

FIG. 3 is a view of the clamp 1 as viewed from the rear side. As shown in FIG.
A pivot shaft 3b of the lid 3 is rotatably supported on the cover 6. In a state where the heater hose HH is not clamped inside, when the lid 3 is to be closed with respect to the main body 2,
As indicated by the two-dot chain line, the gap between the lock portion 25 of the main body 2 and the upper portion 22a of the second fixed portion is located inside the trajectory of the locked portion 3d of the lid portion 3, so that the lock portion 25 and the locked portion 3d are provided.
Does not lock. For this reason, when the clamp 1 in the open state is being conveyed as a component, even if a force is applied from the outside, the clamp 1 is not erroneously locked.

FIG. 4 is a rear view of the clamp 1 in a state where the heater hose HH is fitted into the main body 2. The heater hose HH has a heater hose HH inside as shown by a two-dot chain line in FIG.
It is larger than the inner diameter of the main body 2 where H is not fitted. Therefore, in order to fit the heater hose HH into the main body 2, the main body 2 must be elastically deformed. After the heater hose HH is fitted into the main body 2, the inner diameter r of the main body 2 becomes substantially the same as the outer diameter of the heater hose HH. Then, when the opened lid 3 is closed, as shown by the two-dot chain line, the gap between the lock portion 25 of the main body 2 and the upper portion 22a of the second fixed portion is on the locus of the locked portion 3d of the lid 3. Due to the displacement, the lock portion 25 and the locked portion 3d are locked.

At this time, the locked portion 3d of the lid 3 enters the gap between the lock portion 25 of the main body 2 and the upper portion 22a of the second fixing portion, and the lock claw 3e comes into contact with the tapered portion 25d. , The tapered portion 25d is pushed up to
b is elastically deformed, and the lock claw 3e is fitted and locked in the opening 25c (see FIG. 1) of the horizontal portion 25b. At this time, the elastic deformation of the horizontal portion 25b is restored, and the horizontal portion 25b is completely locked. That is, the lock of the clamp 1 in which the object to be clamped is entered is performed by one touch.

In order to release the lock, a tool such as a flathead screwdriver is used to move the horizontal portion 25b and the locked portion 3 together.
The lock claw 3e is released from the opening 25c by elastically deforming the horizontal portion 25b by inserting the locking claw 3e into the gap with the opening 25c. Therefore, once the clamp 1 is locked, the lock is not easily released by the external or internal force in the normal use state.

A leg 24 is provided at a lower portion of the main body 2.
The leg part 24 is a box-shaped part whose front side is open as shown in FIG. FIG.
FIG. 4 is a perspective view showing a state in which the fixing unit 4 is fixed to the fixing unit 4. The fixing portion 4 is a fixing stay provided on the floor FL of the vehicle. In the clamp 1, a fixing plate 41 provided horizontally on the top of a stay 43 erected on the floor FL is inserted into the leg 24 from an opening on the front side of the leg 24. The fixing plate 41 has a fixing hole 42 formed therein. Here, FIG.
FIG. 6 is a sectional view taken along line AA of FIG. A fixed claw 29 is provided at the bottom of the leg 24. The fixed claw 29 includes a shaft portion 29a provided integrally with the leg portion 24 and a claw portion 29b provided at an end thereof, and the claw portion 29b normally projects into a space in the leg portion. Here, the fixing plate 4 of the fixing portion 4
When the first member 1 enters the leg portion 24, the claw portion 29b is pushed to elastically deform the shaft portion 29a as shown by a two-dot chain line,
9b is pushed down so as not to protrude into the space in the leg portion 24. Then, upon entering the predetermined position, the claw portion 29b is fitted and fixed in the fixing hole 42 provided in the fixing plate 41 by the elastic return force of the shaft portion 29a. Therefore, clamp 1
Are fixed to the fixing plate 41 fixed in the leg 24,
9b maintains that position.

The clamp 1 configured as described above has the following effects. When the clamp 1 is being conveyed as a part, since the fixed object such as the heater hose HH is not fitted to the main body 2, the lock portion 25 is positioned inside the locus of rotation of the locked portion 3d. As a result, locking with the locked portion 3d becomes impossible, and erroneous locking does not occur. On the other hand, at the time of assembling to the vehicle, when a fixed object such as the heater hose HH is fitted to the main body 2,
5 is displaced on the locus of rotation of the locked portion 3d and becomes lockable with the locked portion 3d, so that there is an effect that the lock can be performed with one touch.

Next, a modification of the clamp 1 of the present embodiment will be described. FIG. 7 is a view showing a clamp 201 which is a modification of the clamp 1. The pivot shaft 203b of the lid 203 is rotatably supported by the hinge 226 of the main body 202. In a normal state where no force is applied from the outside, the clamp 201 tries to close the lid 203 with respect to the main body 202, as shown by a two-dot chain line, with the lock 225 of the main body 202. The gap between the second fixed portion 222a and the locked portion 203 of the lid portion 203 is
Since it is outside the locus of d, the lock portion 225 and the locked portion 203d are not locked. For this reason, when the clamp 201 in the open state is being conveyed as a component, it does not accidentally lock even when a force is applied from the outside.

On the other hand, at the time of clamping, the main body 202 is elastically deformed by pressing it so as to narrow the opening, and the lower end of the upper second fixing portion 222a contacts the upper end of the heater hose HH. Then, the gap between the lock portion 225 of the main body 202 and the upper portion 222a of the second fixing portion is displaced along the locus of the locked portion 203d of the lid portion 203, so that the lock portion 225 and the locked portion 203d can be locked. . Therefore, the clamp 201 can be locked by one-touch by pressing the main body 202.

FIG. 8 is a view showing a clamp 301 which is a further modification of the clamp 1. The clamp 301 clamps only one heater hose HH. The clamp 301 also has a heater hose H clamped inside.
In a state without H, when the lid 303 is to be closed with respect to the main body 302, as shown by a two-dot chain line, the main body 3 is closed.
Since the gap between the lock portion 325 and the second fixed portion upper portion 322a is inside the trajectory of the locked portion 303d of the lid portion 303, the lock portion 325 and the locked portion 303d are not locked. For this reason, the clamp 301 in the open state is used as a part.
Is not accidentally locked even when a force is applied from the outside when the sheet is transported. Further, by fitting the heater hose HH into the main body 302, the main body 302 is elastically deformed, and the inner diameter of the main body 302 becomes substantially the same as the outer diameter of the heater hose HH. Although not shown, when the opened lid 303 is closed, a gap between the lock portion 325 of the main body 302 and the upper portion 322a of the second fixing portion is formed.
Is locked on the locus of the locked portion 303d, so that the locking portion 325 and the locked portion 303d are locked. In addition,
It is also preferable that a bent portion 405 is provided on the main body portion 402 so as to be easily elastically deformed, like a clamp 401 of still another modified example shown in FIG.

Although the present invention has been described with reference to one embodiment of the present invention and its modifications, it goes without saying that the clamp of the present invention is not limited to this embodiment.
For example, the object to be clamped is not limited to the rubber heater hose HH, but can also be applied to metal hoses and the like. Also, the present invention can be applied to a wire harness or the like in which a plurality of wires are bundled. Of course, the invention can be applied to three or more hoses. In addition, the present invention can be implemented with various changes such as shape, size, material, quantity, etc., without departing from the scope of the claims.

[0027]

As is clear from the above description, the clamp of the present invention has a simple structure, does not cause erroneous locking during transport, can be easily locked when assembled to a vehicle, and can be easily performed. There is an effect that it does not come off.
