Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fastener used when, for example, cords and pipes installed in the engine room of an automobile are fixed to an interior wall surface.

More specifically, it consists of a base body equipped with a fixing means for fixing it to a suitable panel such as a wall surface, and a clamping body that is pivotally attached to one end of this base via a support shaft and connected to the base so that it can be opened and closed freely. The two ends are overlapped and closed by engaging the locking means provided at the other end of the base body, and the cords or pipes passing between the ends are held in a clamped state to be fastened. In particular, this invention relates to an improvement in a fastener constructed as described above, in which the clamping body, which is pivoted to open and close freely, is kept open before use to transport the fastener. The purpose is to prevent the locking means from being accidentally closed and engaged during the work of fixing cords and pipes in a predetermined location, and to facilitate the work of fastening cords and pipes.

Examples illustrating the present invention will be described below.
To explain its features in detail, Fig. 1 is a front view of the fastener according to the present invention in an open state;
FIG. 2 is a plan view of the above figure, FIG. 3 is an enlarged front view of the main parts, and FIG. 4 is a partially cutaway front view showing the state of use.

In these drawings, numeral 1 is the base body, and 2 is the base body.
is the brake oil pipe 3 in cooperation with this base.
It is a clamping body that clamps and holds pipes such as pipes.

Both the base body and the clamp body shown here are formed in the shape of a horizontally long bar with the same length, and at one end 1a of the base body is a support shaft 4 whose axes are aligned in the front-rear direction. The ends 2a of the matching clamping bodies 2 are each provided with a bearing part 5 that slides on the support shaft 4, and are pivotally connected to each other so that the clamping bodies 2 can be freely opened and closed using the shafts as fulcrums. The other end 1b of the base body 1 is provided with a locking portion 7 that projects a claw 6 outward, and the free end 2b of the clamping body 2 is provided with a locking claw 8 that engages with the locking portion 7. A plurality of recesses for receiving the pipes 3 are provided on each surface that abuts against each other due to the overlapping. 9 and 10 are provided so as to face each other at a laterally spaced interval.

In addition, reference numeral 11 denotes a fixing means that is vertically installed at the center of the lower surface of the base 1 in order to fix the fastener of the present invention to the panel 12, etc. that constitutes the inner wall of the engine room. It is designed to be fixed by pushing it into a through hole 13 formed in 12 as shown in FIG.

By the way, the reference numerals 14 and 15 shown in the figure are the pivoting end portions 1 of the base 1 and the clamping body 2, which are connected to each other about the support shaft as a fulcrum, in order to restrict the free opening and closing of the clamping body 2.
This is a small protrusion provided on the a and 2a sides.

In this embodiment, one of the small protrusions 14 is the support shaft 4.
The other small protrusion 15 is provided on the outer circumferential surface of the bearing part 5 which is slidably and rotatably fitted to the bearing part 5.
It is provided at the end of the

These two small protrusions 14 and 15 each have a small protrusion, so that when the clamping body 2 is rotated from the open state of 180 degrees (the state shown in FIGS. 1 and 2) in the closing direction about the support shaft 5, The tops collide with each other to prevent this rotation in the closing direction (see Figure 3), restricting arbitrary rotation of the clamping body 2 in the open state, while applying further force to the clamping body 2. When the bodies are rotated in the direction of closing, the elastic deformation of the material allows the bodies to overcome the collision and close together. In addition, in order to restrict rotation by the collision of the small protrusions with each other and to enable overcoming by applying force,
In this embodiment, the small protrusion 14 provided on the bearing part 5 is made into a convex arc-shaped protrusion so that it can abut against the other small protrusion 15, and the abutting state can be easily released by the sliding of this convex arc surface. I have made it possible.

The fastener of the present invention is constructed as described above.
The base body 1 and the clamping body 2 are formed separately from synthetic resin, and a bearing part 5 is integrally provided at one end 2a of the clamping body 2.
are connected and combined in series by slidingly fitting them onto a support shaft 4 provided at one end 1a of the base body 1. The clamp body 2 of this fastener is kept open before being used for transportation, storage, etc., and when it is used, the fixing means 11 of the base body is engaged with the through hole 13 made in the panel 12 in this state. and fix it.
After that, the pipe 3 to be piped is fitted into the predetermined recess 9, the open clamping body 2 is closed on the base, and the locking means provided at each end are engaged and locked, thereby securing the pipe. Attach. Of course, when closing this clamping body 2, the small protrusion 1 on the base side
It goes without saying that the restriction on rotation is released by forcibly climbing over the small protrusion 14 on the side of the clamping body that abuts against 5.

As explained above, the fastener of the present invention engages the locking means by overlapping and closing the clamping body 2 which is pivoted at one end to the base body, and clamps and fastens the pipe passed between them. On the other hand, until this fastening work is carried out, the free closing of the clamping body 2 is prevented by the abutment between the small protrusions 14 and 15, and the clamping body 2 is kept in an open state, making it easy to insert pipes. There are advantages to doing so.

In particular, since this type of fastener is assembled in the manufacturing process of automobiles, etc., as can be seen from the above usage example, the clamping body is arbitrarily closed to the base body before assembly, and the engagement of the locking means is performed. If it becomes locked, this engagement has to be released from time to time, which poses a problem that hinders work, but with the fastener of the present invention, arbitrary closing is achieved by the collision of the small protrusions. Since it is regulated and opened in the unfolded state, pipes can be attached to the base as it is, and after that, it is only necessary to close the clamping bodies, which is extremely convenient in terms of work.

In the embodiment described above, one of the small protrusions 14 was provided on the outer peripheral surface of the bearing portion 5, and the other small protrusion 15 was provided to face it. Although this is a necessary condition, the location where it is formed is not limited to the bearing part, but is in the vicinity of the support shaft 4, where it collides with each other when the clamp body is rotated around this support shaft. If so, the conditions will be met and implementation will not be hindered. Further, although the example shows an example of fastening four pipes, it is easily understood from the structure of the fastener of the present invention that the number of fasteners is arbitrary, and that cords outside the pipes may also be used. There will be.
