Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for fixing an object to be mounted using a locking shaft, and more particularly to a holder suitable for holding a brake tube or a fuel tube in a vehicle. .

[0002]

2. Description of the Related Art FIG. 9 shows a supporting state of pipes used in various pipes of an automobile. Holder 3 shown
1 is called a pipe clamp, and clamp parts 30 for holding a pipe are arranged on both sides thereof. In addition, an accommodating portion 34 is arranged at the center of the holder 31, and a stud bolt 33 standing upright from the body panel 32 is inserted therein. In the pipe holding work, the pipe is fitted into the clamp portion 30 and temporarily fixed, and in this state, the opening of the lower surface of the housing portion 34 is applied to the tip of the stud bolt 33. Then, the operation surface 35 is pushed to be housed in the housing portion 34. A plurality of pairs of locking claws 36 are provided inside the accommodating portion 34 so as to face each other, and by engaging these with the stud bolts 33, the entire holder is fixed.

[0003]

In the holder 31 described above, if the stud bolt 33 is not inserted sufficiently, a gap is formed between the holder 31 and the body panel 32, as shown in FIG. Such a gap causes rattling and impairs reliability of holding the pipe.

The occurrence of such problems is due to the difficulty in confirming whether or not the conventional holder has been completely inserted into the stud bolt 33. It is considered that the lift-up from the body panel 32 can be detected by observing it from the side, but it is not easy to find the lift-up because the actual installation location has to be judged from the height direction. Further, the upper surface of the accommodating portion 34 is closed by the operation surface 35, and the engagement state inside cannot be heard from the outside. However, if the operation surface 35
Even if a measure is taken to eliminate the above and open the upper surface of the accommodating portion 34, it is still difficult to clearly determine the positional relationship between the holder and the stud bolt 33, so that the insertion state is still incomplete. It's hard to avoid.
As another measure, the one shown in FIG. 8 is not inconceivable. In this embodiment, the cover 3 is provided on the top surface of the accommodating portion 37.
8 is provided, but the cover 38 is disengaged from the accommodating portion 37 by pushing up the stud bolt 33, and the cover 38 is detached to expose the tip end portion of the stud bolt 33 when completely inserted. It was done like this. For this reason, the cover 38 is slightly connected to the upper edge of the accommodating portion 37 by the thin connecting edge 39, but it is relatively easily separated when the stud bolt 7 is completely inserted. It is configured. However, even if such measures are taken in reality, it is extremely difficult to manufacture accurately the thin connecting edge 39 that is easily broken, and the mounting load increases due to the breakage. This causes a problem that workability is inevitably deteriorated.

The present invention has been developed and devised in view of the above problems, and its purpose is to clearly inform whether or not the locking shaft has been completely inserted, and to ensure a reliable holding state. It is to provide a holder that realizes the above-mentioned, and that does not deteriorate workability due to increased manufacturing load due to easy manufacturing.

[0006]

The structure of the present invention for achieving the above object is a holder for fixing an object to be mounted on a fixing surface, and a clamp for holding the object to be mounted. And a housing portion into which a locking shaft erected from the fixing surface is inserted and engageable with the locking shaft, and the housing is arranged at the top of the housing, and the locking shaft has a predetermined position at the top. It is characterized in that it is configured to include a movable cover that displays a normal inserted state by bulging deformation associated with the protruding operation of the locking shaft when it is fully inserted.

[0007]

When the object to be mounted which is held by the clamp portion is fixed to the fixed surface, when the locking shaft is inserted into the housing portion, the housing portion engages with the locking shaft, so that the entire holder is fixed on the fixed surface. Fixed to. In this case, when the locking shaft is completely inserted to the predetermined depth position of the accommodation portion, the tip of the locking shaft projects the movable cover. As a result, the movable cover undergoes a shape change such as bulging upward, and the operator knows whether or not a predetermined engagement condition has been obtained with the locking shaft based on the presence or absence of this change, and if there is no change. Then, the pushing operation to the locking shaft is performed again, and the insertion state is corrected.

[0008]

The effects of the present invention are as follows. Whether or not a predetermined engagement state is obtained with respect to the locking shaft is clarified by the change in the shape of the movable cover, so that it is easy to confirm the attachment of the holder. Therefore, since the holder is always attached to the fixing surface in a regular state, the attachment target can be reliably fixed without rattling, and the reliability of attachment can be improved.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 4 show a first embodiment of the present invention, in which the holder of this embodiment is for fixing a pipe to be piped on a floor surface 6 of an underfloor of an automobile, To protect from flying stones,
In particular, the protector 2 made of metal is provided.
The protector 2 has a conventionally known configuration, and a through hole 4 for allowing a housing portion 3 (described later) of the main body 1 to project is opened in the central portion. Further, a pair of left and right locking holes 5 penetrate through both sides.

The main body 1 is integrally formed of a synthetic resin material, and an accommodating portion 3 for receiving the stud bolt 7 projecting from the floor surface 6 is arranged in the central portion, and a pipe is held on both sides thereof. The clamp portion 8 for overhanging is projected. In this example, two pieces are arranged on the left side and three pieces are arranged on the right side. Each clamp part 8 has a recess 9 having a size corresponding to the outer diameter of the pipe, and a holding claw 10 projects toward the center of each recess 9. Each holding claw 10 is provided with a bend that allows the pipe to enter the recess 9, and holds the pipe after entering the recess 9 to prevent the pipe from coming off. Further, a pair of left and right protector holding claws 11 is provided on the upper surface of the clamp portion 8 at positions near the left and right ends.
Is erected. Both of the protector holding claws 11 are bent and deformed in a substantially U-shape at their tip ends so that they can be elastically engaged with the corresponding locking holes 5. Reference numeral 12 is a rib for reinforcing each clamp portion 8.

The overall shape of the accommodating portion 3 is as shown in FIG.
The side surface has a substantially elliptical shape, and the inside is formed in a cylindrical shape that opens downward. Further, this internal space serves as an insertion hole 13 capable of receiving the stud bolt 7.
On the other hand, as shown in the figure, the side surface of the housing portion 3 has a window portion 14 opened at a point symmetrical position and communicates with the insertion hole 13. In addition, it is a hole wall in the housing portion 3 and the window portion 1
In the direction orthogonal to 4, four locking claws 15 that can be engaged with the stud bolt 7 are arranged on the right and left sides. Each locking claw 15 protrudes obliquely upward and while changing the height alternately to the left and right according to the pitch of the thread of the stud bolt 7. In addition, each of them is provided with a bend that allows the stud bolt 7 to be inserted therein, and can be elastically engaged with the valley portion of the thread of the stud bolt 7.

A movable cover 16 is provided on the upper surface of the accommodating portion 3 to indicate that the stud bolt 7 is completely inserted, and covers the upper surface of the accommodating portion 3.
The movable cover 16 is formed to be thinner than the main body 1 part, and has a supporting portion 16a that stands upright to the upper edge of the housing portion 3 and a center hinge edge 16c in the center to support both supporting portions 16a. It is composed of a flap portion 16b that connects the two. Side hinge edges 16d are also formed at the connecting portions between the flap portion 16b and both supporting portions 16a, respectively, which allows the flap portion 16b to be deformed so as to reverse its bent state as shown in FIG. It However, when the stud bolt 7 is completely inserted into the accommodating portion 3, the dimensions are set such that the stud bolt 7 can be pushed up, although slightly, from the state shown in FIG. 4 (c). In this case, when the flap portion 16b is stretched horizontally, the movable cover 16 is flexed to allow this.

The holder of the first embodiment is constructed as described above, and the pipe holding work is performed as follows. When the pipes are selected and pressed into the clamp portions 8 corresponding to those sizes, the holding claws 10 bend and are received in the recesses 9, and then the holding claws 10 press the pipes to prevent the pipes from coming off. To do. After this or prior to this, the protector 2 is put on the main body 1. In this case, the protector holding claws 11 engage with the corresponding locking holes 5, and the movable cover 16 is exposed through the through hole 4.

Next, the stud bolt 7 is fitted from the lower surface side of the insertion hole 13 of the accommodating portion 3 and pushed in as it is.
Then, when being pushed in, the locking claws 15 are rubbed against the stud bolts 7 while flexing, and when they are completely inserted, they are elastically engaged with the stud bolts 7, so that the holder holds the pipe. It is fixed to the floor surface 6 in this state.

When the center hinge edge 16c is pushed by the tip of the stud bolt 7 during the process of pushing the stud bolt 7 into the housing portion 3 as described above, the flap portion 16b starts to be pushed up (see FIG. Four
(b) state). Then, when the stud bolt 7 is inserted to a proper depth position, the flap 16b becomes horizontal as shown in FIG. 4 (c) and is stretched between the support portions 16a. Bulges and deforms.
After that, when a further slight push-up is performed, the flap portion 16b is automatically inverted and deformed upward by the elastic force from both the support portions 16a. Therefore, the flap portion 16
The operator can confirm that the stud bolt 7 has been completely inserted based on the change in shape caused by the displacement of b from the lower reversal position to the upper reversal position. Therefore, the regular work is guaranteed, and the reliability of holding the pipe is improved.

Further, in the case of this example, even if the stud bolt 7 does not push up to the inverted position upward, the flap portion 16
Since the reversing operation of b is automatically performed by the elastic force, the stud bolt 7 can be regulated to the required minimum height. This brings about the convenience that the situation in which the work before the pipe holding work is obstructed by the unnecessary protrusion from the floor surface 6 is suppressed.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the movable cover 16 has a thin wall, and has arcuate surfaces on the upper and lower sides so that the movable cover 16 is inverted and deformed. That is, it is always turned downward, and when it is completely inserted into the stud bolt 7, it is turned upward by its own resilience due to the push-up action.

The other structure is the same as that of the first embodiment, and the same effects can be exhibited.

FIG. 6 shows a third embodiment of the present invention. In this embodiment, the movable cover 16 in the second embodiment is used.
The protrusion 17 is projected on the upper surface of the. The other structure is the same as that of the second embodiment, but the state change becomes clearer than that of the second embodiment. FIG. 7 is for further clarification, and the flap portion 16b of the first embodiment is shown.
At both sides with the center hinge edge 16c interposed
8 is arranged. Although both projections 18 are normally closed at their tips, the tips are expanded by being completely inserted into the stud bolt 7.

The present invention can be modified in various ways other than the above-mentioned embodiments. For example, although the pipe clamp is illustrated as the holder in any of the embodiments, the invention can be applied to a cap nut type holder. More specifically,
In order to fix an automobile carpet or the like, it can be applied to a cap nut having a locking claw inside and a pressing flange protruding from the lower edge of the cap nut. Further, as the display means indicating that the insertion has been completed, in addition to the case where only the shape is changed, a method in which a color display section which is always hidden and which appears along with the shape change can be considered.
