Description

[Detailed Description of the Invention] <Industrial Application Field> This invention is a device that is fixed to a panel and used to hold and guide or intermediately support an elongated attached material such as a hollow pipe material or a solid bar material. Concerning a symmetrical plastic holder for.

<Prior Art> Such a bilaterally symmetrical plastic holder has been proposed in Japanese Patent Application No. 53-78963 (Japanese Patent Publication No. 57-54646). This holder is equipped with a pair of opposing clamping pieces that hold the left and right sides of the workpiece in a manner that hugs it almost halfway around the circumference, and each clamping piece is locked by a pair of locking claws directly below the workpiece. Press down on the material to be attached.

<Problems to be Solved by the Invention> For this reason, once the pair of clamping pieces pinches the workpiece from the left and right sides, the workpiece prevents the locking pawl from releasing the lock between the locking claw and each clamping piece. Therefore, the only way to remove the attached material is to cut and remove at least one of the clamping pieces with a knife.

<Means for Solving the Problems> Therefore, the present invention was developed with the aim of strongly holding the object to be attached, while also being able to release the holding as necessary. It has a pair of pillars that stand up opposite each other from the upper surface, and at the upper end of each of the pillars is provided a tongue piece 6 that faces each other and is folded diagonally downward, and at the same time as a tongue piece 6 that faces each other and is folded diagonally downward. At the same time, protrusions 11 that protrude shortly toward each other are provided, and at the tips of each of the protrusions, there is a back surface of a clamping piece 5 that faces each other with a flexible weakened part 12 interposed therebetween to sandwich the workpiece 4. A step-shaped engaging part 8 is provided on the upper back side of each pinching piece to engage with the free end 9 of the tongue piece 6, and the engaging part 8 of each pinching piece 5 is connected to the tongue. It is characterized in that the back surface of the lower part 10 of the clamping piece is brought into contact with the lower surface of the protrusion 11 when engaged with the piece 6.

<Function> The workpiece 4 is passed downward between the tongue pieces 6, 6 which face each other and are folded diagonally downward, and is positioned between the opposing pressure pieces 5, 5, so that each pressure piece 5 Push the tops of each person towards the other person. As a result, each clamping piece 5 bends the weakened part 12 and clamps the attached material 4 from the left and right, and the free end 9 of the tongue piece 6 is attached to the stepped engagement part 8 on the upper back surface of each clamping piece. The clamping pieces are engaged to maintain the clamping state. At this time, the back surface of the lower part 10 of each clamping piece comes into contact with the lower surface of the protrusion 11, so that the clamping piece does not loosen.

To remove the workpiece 4 held between the clamping pieces 6, 6 as necessary, the free end 9 of each tongue is shifted in the axial direction of the workpiece 4, and the stepped engagement of the clamping pieces is removed. What is necessary is to disengage the engagement with the joint portion 8.

<Example> An embodiment of the present invention will be described below.

The holder of the present invention has an integral holding device 1 for holding a workpiece 4 on the upper surface of a base 2 for fixing to a panel.

This holding device 1 is symmetrical with respect to a line 3 passing through the center of a workpiece 4 to be held.

The above-mentioned holding device includes tongue pieces 6 which are opposed to each other and bent diagonally downward from the upper ends of a pair of pillars that stand up from the upper surface of the base, and which are provided facing each other in the middle of the opposing surfaces of the pillars. It has a clamping piece 5.

There are recesses 7 on opposing surfaces of each clamping piece 5,
At the upper part of the back surface opposite to this recess 7, there is a stepped engagement part 8 which engages with the sharp free end 9 of the tongue piece 6. The recess 7 has an arc shape, which is due to the circular cross-sectional shape of the material to be attached.

Each clamping piece 5 is connected midway on the back side via a weakened part 12 to the tip of a protruding part 11 that projects shortly toward the other from the opposing surface of each column. When each clamping piece 5 is attached to sandwich the workpiece 4 from left and right, the back surface of the lower part 10 of the clamping piece is adapted to support or abut the lower surface of the protrusion 11 (fifth
figure). The lower portions 10 of each clamping piece 5 protrude toward the other more than the upper portions, and the recessed portion 7 is shaped as if it were opened diagonally upward.

The action or function of this holder can be inferred from the attached drawings, but will be explained below.

In FIG. 1, the holder is in a state where no workpiece has been attached yet, and the workpiece 4 is located above between the pair of tongues 6, 6. In FIG. 2, the member 4 to be attached is inserted between the pair of tongues, pushes each tongue 6 outward, and is just before entering the space between the recesses 7, 7 of the pair of clamping pieces 5, 5.

As shown in FIG.
5, each clamping piece is pushed in the direction of the arrow as shown in FIG. When the clamping piece 5 is pressed in this manner, the opposing recesses 7 come into contact with the workpiece 4 from the left and right sides. This movement of both clamping pieces 5 surrounds the attached piece, and at the same time the upper part of the protrusion pushes away the free end 9 of each tongue piece 6 upwards and passes under the free end, and when it finishes passing, the tongue piece The free end of is engaged firmly in the step-shaped engagement part 8. Therefore, the material to be attached 4 is firmly attached as shown in FIG.

When the holder holds the material to be attached, each tongue piece 6
Then, not only does the clamping piece engage with the engaging portion 8, but also the back surface of the lower part 10 of the clamping piece comes into contact with the lower surface of the protrusion 11, so that each clamping piece 5 firmly holds the workpiece. .

Then, if the free end of the tongue piece 6 is shifted in the axial direction of the attached material 4 and disengaged from the engaging part 8, the tongue piece 6 and the pressing piece 5 will be moved by elastic restoring force as shown in FIG. Since it returns to the original state, the attached material 4 can be removed if necessary.

<Effects of the Invention> According to the present invention, a reusable plastic material is capable of strongly holding a long and thin workpiece by sandwiching it from both sides, and also allows the workpiece to be removed by releasing the hold as necessary. Can provide holder.

[Brief explanation of the drawing]

The drawings show one embodiment of the plastic holder of the present invention, and FIG. 1 is a front view, and FIGS. 2 to 4 are front views showing the holder shown in FIG. 1 in the order in which objects are attached. , Fig. 5 is a front view of the attached material, in which 2 is the base, 4 is the attached material, 5 is the clamping piece, 6 is the tongue piece, 8 is the engaging part, and 9 is the attached piece.
