Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a pipe holder for holding elongated objects such as automobile fuel pipes and brake pipes to a panel of an automobile body.

2. Description of the Related Art Several pipe holders made of synthetic resin have been developed for holding long objects such as fuel pipes and brake pipes on panels of automobile bodies. For example, in Japanese Utility Model Application Publication No. 57-113775, a pipe holder is described.
Examples are given.

The pipe holder described in the above publication includes a stud fixing part that is fixed to a grooved stud with a groove formed on the outer surface of the shaft of a screw or the like fixed to a panel of a vehicle body, and a hole for receiving the stud fixing part. It is composed of a formed base body and a pipe holding portion that integrally extends laterally from the base body and holds the pipe. When the stud fixing part of this pipe holder is placed against the grooved stud and hammered in, its head presses the pipe holder against a panel such as the vehicle body, and the pipe held by the pipe holder is also fixed to the panel. Ru. This pipe holder allows you to attach the pipe by hammering it in, making it easy to operate.
Although it has the advantage of not requiring the use of screws or nuts, the pipe holder described above does not allow temporary fixing when installing the pipe, making it difficult to adjust the installation position of the pipe.

For this reason, in the pipe holder described in JP-A No. 60-159485, the stud holding part is composed of two cylindrical bodies, and after temporary fastening with the inner cylinder, final fastening is performed by pushing in the outer cylinder. configured to be able to
This solved the above-mentioned problem.

Problems that the invention aims to solve Generally, car bodies are coated with vinyl chloride to prevent rust. Since this coating is applied to the entire surface of the vehicle body, in most cases it is also applied to the shafts of grooved studs that are fixed to the vehicle body. This application increases the diameter of the shaft of the grooved stud by the thickness of the coating. This increase in the diameter of the shaft affected the temporary fixing function of the pipe holder. That is, due to the increase in the diameter of the shaft, a problem has arisen in that the stud holder of the pipe holder cannot be inserted unless the vinyl chloride coating is removed.

On the other hand, there are also pipe holders that utilize a vinyl chloride coating for temporary fixing.
In a pipe holder having such a structure, contrary to the pipe holder described in the above publication, if the thickness of the coating on the outer surface of the shaft of the grooved stud is thin, or if there is no coating on the outer surface of the shaft, ,
There is a problem that the temporary fixing function is lost.

Therefore, the purpose of the present invention is to provide a grooved stud with a coating of vinyl chloride or the like to increase the diameter of the shaft, or even without any coating at all.
To provide a pipe holder which can be temporarily fastened to a grooved stud and can then be permanently fastened easily.

Means for Solving the Problems In order to achieve this purpose, according to the present invention,
A stud fixing part fixed to a grooved stud fixed to a panel, a base body formed with a hole for receiving the stud fixing part, and a pipe extending sideways from the base body and being pushed in through an open part. The stud fixing part is formed integrally with the hollow shaft part that receives the stud, and is pressed to fix the pipe holding part to the panel. A pipe holder is improved having a head with a head. The base of the pipe holding part of the pipe holder according to the present invention is formed into a hollow cylindrical body that receives the shaft part of the stud fixing part, and the inner surface of the base has:
A locking portion is formed on the outer surface of the shaft portion of the stud fixing portion to removably connect the pipe holding portion to the stud fixing portion, and the tip of the cylindrical base body is provided with the groove. A locking pawl is formed to temporarily fix the stud in the groove of the stud, and a spiral thread is formed on the inner surface of the shaft of the stud fixing part, the diameter of which decreases to a smaller diameter than the outer diameter of the stud. The lead angle is
When the stud fixing part is applied to the stud and tapped, it is formed at a large angle that allows the stud to move forward while removing the coaching of the stud while rotating. It is characterized in that a large diameter portion that is larger than the outer diameter of the grooved stud is provided in a portion other than the threads on the inner surface of the shaft portion.

Figure 6 shows this coaching 7
It also shows how the pipe holder 1 of the present invention temporarily and permanently fastens the threaded stud 6 to which it has adhered.

The structure of the pipe holder 1 of the present invention will be described in detail with reference to FIGS. 1 a to 2 f and 2 a to e. The pipe holder 1 is composed of two parts: a stud fixing part 11 shown in FIGS. 2a to 2e, and a pipe holder 12 shown in FIGS. 1a to 1f. The stud fixing part 11 receives and grasps the threaded stud 6 as a grooved stud fixed to the panel 5, and fixes the pipe holding part 12 to the panel 5. The pipe holding part 12 is integrally formed with a cylindrical base body 14 in which a hole 13 (see FIG. 1 d and e) for receiving the shaft of the stud fixing part 11 is formed, and extends laterally on both sides from this base body. Multiple pipe grip parts 1
It consists of 5, 16, 17, and 18.

Each of the pipe grip parts 15 to 17 is formed in a substantially U-shaped trough shape with an open upper part, and an elastic wing 19 is formed from the upper end of the trough to extend diagonally toward the bottom surface, and the pipe grip part 19 that is pushed in is I'm trying not to let it slip away. Note that details of its configuration, operation, and effects will be described later.
Note that it is preferable that reinforcing ribs 20 be formed on the bottom surface of the pipe holding portion 12.

The stud fixing part 11 includes a hollow shaft part 21 that receives the threaded stud 6, and a large diameter head that is integrally formed at the lower end of this shaft part 21 and presses and fixes the base body 14 of the pipe holding part 12 to the panel 5. 22. As shown in FIGS. 2b and 2e, the tip of the shaft 21 is formed with a recessed locking portion 25 that locks into the protruding locking portion 24 inside the base 14 of the pipe holding portion 12. As shown in Figure 4c,
A stud fixing part 11 is removably connected to a pipe holding part 12. In this connected state, the head 22
When tapped with a hammer or the like, the locking parts 24 and 25 are uncoupled, and when hammered in further, the shaft 21 advances through the hole in the base 14 of the pipe holding part 12 and the head 22 comes into contact with the base 14. come into contact with Therefore, the head 22
By striking the pipe holder 1 into the stud 6
The pipes 2 and 3 thus held are fixed to the panel 5. The head 22 is preferably formed into a hexagonal shape as shown in the figure so that it can be rotated by a tool or the like. This configuration also makes it easy to remove the pipe holder 1 from the stud 6 by rotating the head 22.

In the present invention, the cylindrical base body 14 of the pipe holding part 12 has a locking pawl 26 formed at its distal end for temporarily fixing it in the groove of the screw stud 6. As shown in FIGS. 1a and 1e, this temporary fastening locking claw 26 is
A pair of holes are formed at the upper end, that is, the tip, of the cylindrical base 14 so as to face each other. Since this locking pawl 26 has a temporary fixing function, it is preferable that a slit 27 be formed on the side edge of the locking pawl 26 so as to have elasticity.

In the present invention, the above-mentioned temporary fixing locking claw 26
As shown in the figure, each pawl is formed so as to engage with the outer periphery of the shaft portion of the screw stud 6 in a V-shape. By forming the stud in this manner, it bites into the outer peripheral surface of the stud, so that the temporary fixing function of the nail is maintained at a high level regardless of the thickness of the vinyl chloride coating. In particular, as shown by the arrow in FIG. 4c, the tip end of the claw can be easily bent toward the opening side, and it can be easily pushed into the threaded stud 6.

The most important features of this invention are:
On the inner surface of the hollow portion of the shaft portion 21 of the stud fixing portion 11, a thread 28 having a diameter smaller than the outer diameter of the threaded stud 6 is formed in a spiral shape.
This thread 28 serves as a locking claw for fixing the pipe holder 1 to the panel 5, and as shown in FIG. Even if 7 is attached,
It has a function of reliably fixing and locking the coating 7 while scraping it off. In particular, as shown in the figure, the thread 28 is formed in a spiral shape with a lead angle considerably larger than that of a normal screw, and the lead angle rotates when the stud fixing part 11 is placed against the stud 6 and tapped. When the head 22 of the stud fixing part 11 is hammered in, the tip side (the upper side in the drawing) of the helical thread 28 is formed at an angle that allows the stud to move forward. Scrape it off and move on. The stud fixing part 11 rotates when driving in due to the spiral ridges 28, and this has the effect that the ridges of the stud 6 bite into the tops of the ridges 28 to cut the thread. be.

As mentioned above, the shaft portion 21 of the stud fixing portion 11
When it is pushed into the stud 6, it bites into the ridges of the threaded stud 6 and is locked, but as shown in the figure, the inner surface of the shaft 21 other than the ridges 28 is smaller than the outer diameter of the threaded stud. A large-diameter portion 29 is provided, and the coating 7 scraped off by the threads 28 is collected in this large-diameter portion 29. Furthermore, in the present invention, in addition to the first thread 28, the inner surface of the shaft portion 21 of the stud fixing portion 11 has an inner diameter slightly larger than the outer diameter of the threaded stud 6 but smaller than the outer diameter of the coating 7. The second spiral crest 30 decreases in diameter to
is preferably formed at a position away from the first ridge 28. This second ridge 30 provides a coaching 7 prior to the first ridge 28.
, and the coating of the first thread 28 is enabled to ensure that the first thread 28 is threaded into the thread of the threaded stud 6, as shown in FIG. , the engagement of the thread 28 with the stud becomes strong and reliable.

An example in which several pipes 2 and 3 are fixed to a panel 5 of a vehicle body or the like using the pipe holder 1 according to the present invention is shown in FIGS. 4 to 7. Hereinafter, the operation of the pipe holder 1 according to the present invention will be explained. The configuration, operation, and effects of the pipe grip section 18 of the pipe holding section 12 will be described later.

In the pipe holder 1 according to the present invention, as shown in FIG. 4a, the shaft part 21 of the stud fixing part 11 is inserted into the hole of the base body 14 of the pipe holding part 12, and as shown in FIG. 4c, The protruding locking portion 24 of the base body 14 of the pipe holding portion is locked with the recessed locking portion 25 of the shaft portion 21 of the stud fixing portion to form an integral assembly. This state becomes the packaging for delivery to the user (for example, a pipe processing manufacturer, etc.).

In order to fix each pipe 2, 3 to a panel 5 of a vehicle body or the like using the pipe holder 1 of the present invention which is an integral assembly, first, the pipe grip part 15 of the pipe holder 12 is fixed. - 18 are made to hold the required pipes 2 and 3 by pushing them in through the upper openings. This situation is illustrated in Figure 4a. From this state, the operator places the upper end, that is, the tip, of the base 14 of the pipe holder 12 against the tip of the screw stud 6 fixed to the panel 5 of the vehicle body, etc., and pushes it in with a finger or the like. As a result, the temporarily fastening locking claws 26 of the base body 14 are attached to the coating 7 made of vinyl chloride or the like, as shown in FIG.
It bites into and locks. That is, the holder 1 is temporarily fastened to the screw stud 6. Of course, if there is no coating 7, the temporary fastening locking claws 26 will lock into the valleys or grooves of the threaded stud 6 to temporarily fasten the holder 1 to the threaded stud 6, as shown in FIG. do. In this way, the holder 1 is temporarily fixed to the screw stud 6 regardless of the presence or absence of the coating 7, so that the positions of the pipes 2 and 3 on the panel 5 of a vehicle body or the like can be corrected to an appropriate arrangement.

After the pipes 2 and 3 are placed in proper positions, the head 22 of the stud fixing part 11 is hammered in, for example, with a hammer or the like, and the locking part connecting the stud fixing part 11 and the pipe holding part 12 is removed. 24 and 25
When the lock is released, the shaft portion 21 of the stud fixing portion 11 advances within the base body 14 of the pipe holding portion 12, receives the tip of the threaded stud 6, and further advances.
As a result of this approach, as shown in FIG. 6, the second ridges 30 of the stud fixing portion 11 begin to scrape off the coating 7, and the scraped coating 7 is accumulated in the large diameter portion 29 as it advances. In addition, while the first thread 28 further deeply scrapes the coating 7, the shaft portion 21
proceeds to accept stud 6. That is,
Since the coating on the threaded portion of the screw stud 6 to be permanently fastened is removed, it does not have any adverse effect upon the final fastening. When the stud fixing part 11 advances toward the panel 5 by being hammered in, the head 22 of the stud fixing part 11 presses the lower surface of the pipe holding part 12 so as to fix it to the panel 5. Of course, during this driving, the first helical thread 28 advances while rotating, whereby the thread of the stud 6 bites into the top of the thread 28 to cut the thread. The ridges 28 are therefore firmly fixed to the threaded studs 6, thereby fixing the pipes 2, 3 to the panel 5.

The structure of the pipe grip sections 15 to 18 of the pipe holding section 12 will be explained. The pipe grip portion is configured to hold pipes of different diameters. Each pipe grip part is formed in the shape of a substantially U-shaped trough that is open at the top, and elastic wings 19 are formed from the two upper ends of the trough, respectively, toward the bottom surface. This wing 19 is composed of wings 32 and 33 of different lengths. Of these wings 32, 33,
Reference numeral 32 is a short wing that holds a large diameter pipe, and reference numeral 33 is a long wing that holds a narrow diameter pipe. Note that when a thick pipe is inserted and held in the grip part 18, the second
The wing 33 is left bent.

Further, it is preferable that a rib 36 extending in the longitudinal direction is formed at the center of the inner bottom surface of the pipe grip portion. The ribs 36 not only reinforce the pipe grip but also stably support the pipe. Furthermore, it is preferable that a pair of elastic holding pieces 37, 37 are formed on the bottom surface, so that the received pipe can be stably held at the center of the grip part 18.
This holding piece 37 is also suitable for stably holding a thin pipe without wobbling from side to side.

Preferably, a pair of guide ribs 38 are formed on the inner wall surface of the pipe grip portion 18, facing each other and extending vertically in the middle thereof. Due to the presence of the guide ribs 38, the accommodated pipe can be positioned in the center of the grip portion, the insertion force is stable, and the withdrawal force can be sufficiently resisted. Furthermore, in order to hold the pipe stably, ribs 40 extending in the longitudinal direction are provided on the inner wall surface of the grip portion at an intermediate height position.
Preferably, 40 is formed.

The pipe grip section having such a structure can hold a pipe 2 with a large diameter or a pipe 3 with a small diameter, as shown in FIG. In particular, in the case of a pipe 3 having a small diameter, the second elastic wings 33 act to hold the pipe 3 so that it does not slip out. The holding pieces 37, 37 also push up the pipe 4 from below and hold the pipe stably.

Effects of the invention In the present invention, the base of the pipe holding part is formed into a hollow cylindrical body that receives the shaft of the stud fixing part, and the inner surface of the base has a locking part for the outer surface of the shaft of the stud fixing part. A locking portion is formed to removably connect the pipe holding portion to the stud fixing portion by being locked to the stud, and a locking pawl is formed at the tip of the cylindrical base body to temporarily lock the pipe holding portion to the groove of the grooved stud. The inner surface of the shaft of the stud fixing part is spirally formed with a thread whose diameter is smaller than the outside diameter of the stud. It is formed at a large angle that allows the stud to advance while rotating, and the spiral ridges lock onto the ridges of the stud, and the outer diameter of the grooved stud is Because of the large diameter section, the studs are always stable, even if the outer surface of the threaded stud is coated with vinyl chloride or other coatings, and even if the stud is not coated with such a coating. Therefore, the pipe holder can be temporarily fastened to the stud regardless of the presence or absence of coating. Even when it is permanently fastened by hammering, extremely reliable and stable fixing force can be obtained without being hindered by coaching.

In particular, according to the pipe holder of the present invention, when the stud fixing part is hammered into the stud for final fixing, the locking part for final fixing consisting of spiral threads rotates and holds the grooved stud. As the stud progresses by removing the coaching, the threads of the stud cut into the top of the spiral thread that will become the locking part for final fastening and are threaded. It is firmly fixed to the threaded stud, and the pipe is firmly and stably fixed to the panel.
