Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the construction of a hose support known as a high horse mast.

[Prior Art] A hose support (high hose mast) is used to maintain a hose of a refueling system in an upwardly erect state. FIG. 3 shows a conventional oil supply device equipped with such a hose support. Lubrication device 1
is installed on island 2 on ground G,
A hose support 5 for supporting the hose 4 upward is provided at the upper end of the side surface of the oil supply device main body 3. The hose support 5 includes a flexible rod 6, a hose fitting 7 on the flexible rod 6, and a fitting for attaching to the oil supply device main body 3. Such a hose support 5
By providing this, even if the hose has a length exceeding a certain value, the hose will not come into contact with the ground G or the island 2, and as a result, contamination and damage to the hose will be prevented, and the hose will Prevents being stepped on by people or hit by cars,
It's convenient. Therefore, this type of hose support is used not only to support oil supply hoses, but also to support spray type car wash hoses and oil change hoses.

However, in the conventional hose support 5, the flexible rod 6 is integrally and directly connected to the hose fitting 7, and the flexible rod 6 and the hose fitting 7 cannot rotate relative to each other. I couldn't do it. Therefore, bending stress tends to concentrate on the portion of the hose 4 that is fixed with the hose fitting 7, and unnatural twists tend to occur, resulting in poor operability of the hose 4 and nozzle 9, and shortening their lifespan. There was a drawback.

To deal with this drawback, a swivel joint is interposed between the flexible rod 6 and the hose fixture 7,
A technique has also been proposed in which the swivel joint allows relative rotation between the flexible rod 6 and the hose fixture 7, thereby improving the operability of the hose and preventing twisting. This has improved the operability of the hose to some extent, but since the swivel joint only allows horizontal rotation, that is, rotation around the longitudinal direction of the hose fitting 7, the hose cannot be attached to the flexible rod 6. Tool 7 cannot be tilted. Therefore, even if the hose support 5 is equipped with a swivel joint, resistance may occur when moving the hose 4 or nozzle 9, resulting in insufficient operability. The hose 4 may be bent or twisted suddenly, and the hose 4 may be damaged.

[Object of the Invention] The present invention was proposed in view of the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a hose support that can improve the operability of the hose and extend the life of the hose. The purpose is

[Structure of the Invention] The hose support of the present invention includes a hose fixture, a ball joint whose one end is connected to the hose fixture and whose other end is connected to a flexible rod, and a flexible rod. a hose retaining ring provided at the lower part, and the flexible rod is connected to the ball joint at one end and has a female threaded section at the other end to be screwed into one end of the spring member. an upper rigid body part, and a lower rigid body having a female screw part at one end that is screwed to the other end of the spring member, and a coupling means for coupling to a fitting attached to the oil supply device case at the other end. and a spring member having one end threadedly engaged with the upper rigid body part and the other end threadedly engaged with the lower rigid body part.

When implementing the present invention, it is preferable that the portion where the ball joint is provided can be covered with a dust cover.

[Operation of the invention] According to the present invention having the above configuration,
Since the ball joint can rotate freely in any direction, the flexible rod and the hose fixing device can freely rotate relative to each other, and as a result, the hose or the nozzle at the end of the hose can be easily moved. Improved maneuverability when moving hoses and nozzles. Furthermore, the life of the hose is extended because sudden bending or twisting of the part of the hose to which the hose fitting is attached is prevented.

Here, if the connection to the spring part is made by welding or welding, there is a risk that stress caused by bending the spring part will concentrate on the end of the connection part and damage the member in that part. The rod is composed of two divided rigid parts and a spring part interposed between them, and a female thread is formed at the connection part between the rigid part and the spring part so that the end of the spring part can be screwed into it. Therefore, the connection is made by threading the spring part and the female screw. Therefore, stress is generated throughout the connection and damage to the components is avoided.

Further, when the hose separates from the hose support and comes to a position 4' as shown by the dotted line in FIG. 3, there is a risk that the hose may hide the various numbers N displayed on the display section 10. In contrast, in the present invention, since a retaining ring is formed below the flexible rod, the hose can be arranged along the hose support by passing the hose through the retaining ring. I can do it. If the hose is disposed along the hose support, the above-mentioned problem of hiding various numbers can be solved.

Furthermore, if the part where the ball joint is provided can be covered with a dust cover, it is possible to prevent the smooth rotation of the ball joint from being disturbed due to the intrusion of dirt and dust. In addition, the dust cover has the design effect of improving the appearance as a so-called "rag cover".

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. Here, FIG. 1 shows in detail one embodiment of a hose support 20 of the present invention, and FIG. 2 shows the entire oil supply device 22 having this hose support 20. As shown in FIG.

The refueling device 22 is installed on an island 24 on the ground G of the gas station, and its configuration is similar to that of the refueling device 1 shown in FIG. 3, except for the portion related to the hose support 20.
is almost the same as

In the main body 26 of the refueling device 22, a hose support 2 for supporting the hose 32 is provided above the side portion 30 on the side where the various refueling data input boards 28 are provided.
0 is attached.

In FIG. 1, the hose support 20 includes a hose fixture 34, a flexible rod 36, and a fitting (main body fitting) 38 for attaching the hose to the main body of the oil supply device.
4 and the flexible rod 36 is a ball joint 4.
0 is interposed.

The hose fixture 34 has an upper half 44 and a lower half 46.
and bolts 48, 48 that connect them. After the hose 32 is held between the upper half 44 and the lower half 46, the bolts 48, 48 connect the upper half 44, the hose 32, and the lower half. The portions 46 are joined together to secure the hose 32.

The lower half 46 of the hose fixture 34 is integrally connected to a joint support 52 on the ball member 50 side of the ball joint 40, and
0 and the ball side joint support 52 are threaded portions 54
They are connected by screws. The ball member 50 is connected to the receiver member 56 so as to rotate relatively freely and smoothly. The receiver member 56 is coupled to the receiver-side joint support 60 by a threaded portion 58 .

The flexible rod 36 includes an upper rigid portion 62, a spring portion 64,
It is generally constituted by a lower rigid body part 66. still,
In FIG. 1, the upper rigid portion 62 is shown partially broken away. The upper rigid body part 62 is connected to the ball joint 4 by a retaining pin 68 at one end thereof.
It is connected to the receiver-side joint support 60 of No. 0, and a female threaded portion 70 is formed at the other end to be screwed into one end of the spring portion 64. A similar female screw portion 72 is also formed at the upper end of the lower rigid body portion 66, and the other end portion of the spring portion 64 is screwed into the female screw portion 72. The lower rigid portion 66 is integrally connected to the main body attachment 38.

In FIG. 1, reference numeral 74 indicates a dust cover surrounding the ball joint 40. One end of the dust cover 74 is inserted into the tip of the upper rigid portion 62 of the flexible rod 36, and the other end is in contact with the surface of the lower half 46 of the hose fixture 34. When cleaning of the ball joint 40 is necessary, the dust cover 74 can be turned over.

Further, reference numeral 76 in FIG. 1 indicates a retaining ring for the hose 32, and the hose 32 is passed through the hole 78.

In the hose support 20 configured as described above, the flexible rod 36 follows the movement of the hose 32 and the nozzle 33 (FIG. 2) due to the elasticity of the spring portion 64. can move.

In addition, the ball member 50 of the ball joint 40
Since the receiver member 56 can perform any relative rotation, the hose fixture 34, which is fixed to the ball member 50, and the upper rigid body part 62, which is fixed to the receiver member 56, are relatively free. Therefore, the hose 32 held by the hose fixture 34 and the flexible rod 36 can freely rotate or tilt with respect to each other, and the hose can be rotated or tilted in any direction. 32 is prevented from sharp bending or twisting.

Furthermore, the dust cover 74 is attached to the ball joint 4.
It also has the design effect of preventing dust from entering the ball joint 40 and acting as a so-called "rag cover" to prevent the structure of the ball joint 40 from being seen from the outside.

Furthermore, since the spring portion 64 is connected to the upper rigid body portion 62 and the lower rigid body portion 66 by threading the ends of the spring portion 64 to the female screw portions 70 and 72, bending of the spring portion 64 is possible. The stress caused by bending and bending occurs throughout the female threaded portions 70, 72, and damage to the rigid body portions 62, 66 and the spring portion 64 due to stress concentration is prevented.

In addition, if the hose 32 is passed through the hole 78 of the retaining ring 76 provided in the lower rigid part 66, the hose 32 is always arranged along the flexible rod 36, and the slack in the hose 32 allows oil to be supplied. Display section 2 of device 22
7 (FIG. 2) is prevented from being hidden.

In addition, as shown in FIG.
When not pulled, the coil spring 59 keeps the ball joint 40 straight as shown in the figure, giving a good appearance.
