Japanese Patent Laid-Open No. 9-152064

However, in the conventional pipe clamp 1 shown in FIG. 4, since the shape of the pipe support portion piece 30 is fixed, when a new type of vehicle is developed and a new type pipe is used, the pipe diameter is large. There is a problem that a new pipe clamp has to be designed each time. That is, when using a new type of pipe having a pipe diameter different from that of a pipe normally used, there is a problem that a pipe clamp adapted to the new type of pipe must be prepared each time. In addition, there has been a demand for the pipe clamp to hold the pipe securely.
The present invention has been made in view of the above problems, and a problem to be solved by the present invention is to reliably hold a pipe while supporting a new type of pipe in a pipe clamp. .

In order to solve the above-mentioned problems, the present invention takes the following means.
First, the first invention is a pipe clamp for holding a long pipe at an appropriate position in the longitudinal direction, and has a space volume capable of holding the long pipe inside, In order to insert the pipe into the space volume position that holds the pipe of the clamp body, the clamp body is formed as a plate-shaped member from the opening position of the gate shape of the clamp body. It is arranged to extend in the direction of the space volume position holding the pipe inside, and in the free state it is arranged in a state where the opening size is smaller than the diameter of the pipe to be held. In order to receive and support the pipe inserted into the space volume holding the pipe of the clamp body, It is arranged at a position corresponding to the space volume for holding the pipe at the internal position of the clamp body from the arrangement position of the piece insertion holding part piece, and extends as a plate-shaped member from both sides of the portal shape of the clamp body. In a state where the pipes are connected in a connected manner, the pipes are arranged in a convex shape in the insertion direction, the elastic force in the reduced diameter direction is given to the pipes to be inserted, and the diameter of the pipe to be inserted is And a pipe support part piece configured to change a holding angle for receiving the pipe, and the pipe inserted into the space volume holding the pipe of the clamp body has the diameter according to the size of the pipe. The pipe support part piece is changed and supported, and the pipe insertion holding part piece for inserting the pipe is held at its tip in the free state.

According to the first aspect of the invention, the pipe is held at the position of the space volume between the pipe insertion holding part piece and the pipe support part piece located inside the clamp body from the pipe insertion holding part piece. And this pipe support part piece is arrange | positioned in the position corresponding to space volume, when a pipe is hold | maintained. That is, the pipe support part piece is at a position where a space volume can be formed in accordance with the pipe diameter of the pipe to be inserted.
Moreover, since the pipe support part piece is disposed as a convex shape in the pipe insertion direction, the pipe can be smoothly inserted into the space volume. And the pipe support site | part piece becomes a structure by which the elastic force was provided to the diameter reduction direction with respect to the pipe inserted. Since the pipe is sandwiched between the pipe insertion holding part piece and the pipe support part piece by this elastic force, the pipe can be reliably held. Furthermore, since the pipe support part piece has a configuration in which the holding angle for receiving the pipe changes according to the diameter of the pipe to be inserted, the pipe support part can be adapted to a so-called new type pipe.

  The pipe inserted into the space volume is supported by changing the pipe support part piece according to the size of the pipe. Thereby, a pipe can be reliably hold | maintained within space volume. In addition, since the pipe is held at the tip of the pipe insertion support part piece in the free state, the pipe can be held in a well-balanced manner within the space volume.

  Next, the second invention is a pipe clamp according to the first invention described above, wherein the plate-shaped members extending from both sides of the gate shape of the clamp body of the pipe support part piece are connected and connected. Are connected and connected as a configuration arranged in an inverted U shape with respect to the insertion direction of the pipe by a member that can be elastically deformed at the center position between them, and the inverted U-shaped portion is elastically deformed and inserted. It is possible to cope with the size of the pipe diameter.

  According to the second aspect of the invention, the pipe support part piece extends from both sides of the gate shape of the clamp body as a plate-like member and is connected and connected, and the connected and connected pipe support part piece is an elastically deformable member. It is said that. And the location which becomes reverse U shape with respect to the insertion direction of a pipe is arrange | positioned and comprised in the center position of the plate-shaped member extended from both sides. As a result, the elastic force in the reduced diameter direction acts on the inserted pipe strongly, so that the pipe can be firmly held in the space volume. In addition, since this inverted U-shaped portion is appropriately deformed and inserted into the space volume with a configuration that can accommodate the diameter of the pipe to be inserted, a new type of pipe can be accommodated.

Next, the third invention is the pipe clamp according to the second invention described above, wherein the inverted U-shaped portion which is the connecting and connecting portion at the center position of the pipe support portion piece is on the back as viewed from the pipe insertion direction. A pipe clamp characterized in that a reaction force support portion formed integrally and projecting from a clamp body is disposed in a contact state and receives a holding reaction force of an inserted pipe.
According to the third aspect of the invention, since the inverted U-shaped portion and the reaction force supporting portion receive the holding reaction force of the pipe inserted in a contact state, the pipe can be held in a stable state. it can.

Next, according to a fourth aspect of the present invention, in the pipe clamp according to any one of the first to third aspects, the pipe insertion holding portion piece extends from both side positions of the gate shape of the clamp body. It is characterized by being arranged.
According to this 4th invention, a pipe can be hold | maintained more reliably by the pipe insertion holding | maintenance part piece extended and arrange | positioned from the both sides position of the gate-shaped shape of a clamp main body.

The present invention can obtain the following effects by taking the above-described means.
First, in the first aspect of the invention, the pipe can be reliably held while supporting a new type of pipe.
Next, according to the second invention, the pipe can be firmly held in the space volume.
Next, according to the third invention, the pipe can be held in a stable state.
Next, according to 4th invention, a pipe can be hold | maintained more reliably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The best embodiment of the present invention will be described in detail below with reference to the drawings.
FIG. 1 is a perspective view showing a pipe clamp 1 according to the present embodiment. FIG. 2 is a front view showing the pipe clamp 1 according to the present embodiment.
The pipe clamp 1 is used to hold a pipe such as a brake fluid pipe of an automobile and prevent the pipe from rattling or falling off. For example, the pipe clamp 1 can be fixed to the floor of the vehicle body, and the brake fluid pipe can be held on the pipe clamp 1 for use. In addition, the size of the pipe clamp 1 can be appropriately changed according to the type of vehicle such as an ordinary car, a light car, and a large car.

As shown in FIG. 1, the pipe clamp 1 has a space volume C capable of holding a long pipe inside, a clamp body 10 formed with one end opened, and a pipe of the clamp body 10. A pipe insertion holding part piece 20 for inserting a pipe into a holding space volume position and a pipe support part piece 30 for receiving and supporting the pipe inserted into the space volume C holding the pipe of the clamp body 10 are provided. Yes.
Moreover, the pipe clamp 1 is integrally formed with the synthetic resin material, and the clamp main bodies 10 and 10 provided in the left-right direction as viewed in FIG. 1 have the same size and shape. Thereby, it can be made to fix to a structural member, such as the floor surface of a motor vehicle, in a stable state and with good balance.

  Further, as shown in FIG. 1, the pipe clamp 1 is attached to a locking shaft (for example, a stud bolt) formed at a substantially central position as seen in FIG. A mounting portion 70 is provided. A circular hole (not shown) is formed in the pipe clamp 1 substantially at the center of the bottom surface of the mounting portion 70, and this hole is configured to be fitted with a locking shaft such as a stud bolt. .

  The pipe insertion holding part piece 20 is formed to extend from the gate-shaped opening position K of the clamp body 10 toward the inside of the gate-shaped shape having the space volume C. Specifically, in the clamp body 10 on the right side as viewed in FIG. 1, the pipe insertion support portion piece 20 on the left side as viewed in FIG. 1 extends from the lower left opening position K of the clamp body 10 toward the upper right space volume C. Is formed. The right pipe insertion support portion piece 20 as viewed in FIG. 1 is formed to extend from the lower right opening position K of the clamp body 10 toward the upper left space volume C. Both the right and left pipe insertion holding part pieces 20 are formed in a plate shape and are arranged in a state where the opening size is smaller than the diameter of the pipe to be held in the free state. In some cases, the size of the opening can be expanded and deformed.

  The pipe insertion holding part piece 20 is arranged extending from both side positions of the gate shape of the clamp body 10. Thereby, the pipe accommodated in the space volume C can be hold | maintained more reliably. In order to hold the pipe in a more stable state, it is desirable that the pipe insertion holding portion pieces 20 have a positional relationship facing each other.

The pipe support part piece 30 is a member for receiving and supporting a pipe inserted into the space volume C. That is, the pipe support part piece 30 is disposed inside the gate shape of the clamp body 10 rather than the pipe insertion holding part piece 20, and the space volume between the pipe insertion holding part piece 20 and the pipe support part piece 30. The pipe is supported in C.
Moreover, the pipe support part piece 30 is provided as a convex shape in the insertion direction of the pipe in a state where it extends as a plate-shaped member from both sides of the gate-shaped shape of the clamp body 10 and is connected. Thereby, since insertion along the outer diameter shape of a pipe is attained, a pipe can be smoothly inserted into the space volume C.

  As shown in FIG. 2, the articulated connection of the plate-shaped members disposed extending from both sides of the gate-shaped shape of the clamp body 10 in the pipe support part piece 30 is relative to the insertion direction of the pipe at the center position between the two. In other words, they are tangentially bonded at the portion formed in an inverted U shape. The inverted U-shaped portion 32 is formed of a member that can be elastically deformed, and an elastic force that returns to the acting force that opens the inverted U-shaped portion 32 works. Thereby, since the elastic force in the direction of diameter reduction with respect to the inserted pipe acts strongly, the pipe can be firmly held in the space volume C. In addition, the inverted U-shaped portion 32 arranged in an inverted U shape is appropriately deformed with a configuration that can accommodate the size of the diameter of the pipe to be inserted, and therefore can be adapted to a new type of pipe. .

  Specifically, the pipe support part piece 30 exerts an acting force in the diameter reducing direction on the inserted pipe. In the clamp body 10 on the left side as viewed in FIG. 2, when the pipe is inserted into the space volume C, the pipe support part piece 30 is applied with the acting force in the diameter reducing direction A indicated by the arrow in the drawing. As a result, the pipe insertion holding part piece 20 and the pipe support part piece 30 form a space volume C corresponding to the diameter of the pipe when the pipe is inserted, so that there are many types without depending on the pipe diameter. Can hold the pipe. In addition, the pipe can be reliably held in the space volume C.

  Therefore, the holding angle at which the pipe support part piece 30 receives the pipe changes according to the diameter of the pipe to be inserted. For example, when a pipe having a large pipe diameter is inserted into the space volume C, the pipe support part piece 30 expands and deforms, and the holding angle (the angle surrounding the pipe with the left and right pipe support part pieces 30 and 30) gradually increases. It changes to become smaller. Thereby, even when using a so-called new type of pipe, it is possible to save the trouble of newly designing the pipe clamp.

The inverted U-shaped portion 32 is provided with a reaction force support portion 12 formed integrally projecting from the clamp body 10 on the back as viewed from the pipe insertion direction, in contact with the inserted pipe. It is configured to receive power. That is, in FIG. 2, the reaction force support portion 12 is formed to project from the upper portion of the clamp body 10 that is upward when viewed from the direction of the opening position K into which the pipe is inserted. Thereby, since it becomes the structure which receives the holding | maintenance reaction force of the pipe inserted in the contact state, the reverse U-shaped part 32 and the reaction force support part 12 can hold | maintain a pipe in the more stable state.
Also, the portion 34 of the inverted U-shaped portion 32 that supports both the right and left pipe support portion pieces 30 in contact with the pipe as viewed in FIG. 2 is formed thick. On the contrary, the coupling part 36 of the both pipe support part pieces 30 to the clamp body 10 is formed thin, and the pipe support part piece 30 is easily expanded and deformed as the pipe is inserted. Thereby, when a slightly smaller pipe is inserted, it becomes easy to fit the pipe with the pipe support part piece 30.

Then, the usage method of the pipe clamp 1 which concerns on this embodiment is demonstrated.
FIG. 3 is a front view showing a state in which the pipes P1 and P2 are accommodated in the space volume C. FIG. For convenience of drawing, the pipes P1 and P2 are shown in cross-sectional views. Here, a mode in which pipes P1 and P2 having different pipe diameters are inserted into the pipe clamp 1 and the state shown in FIG. 3 will be described.
First, a mode in which a pipe P1 having a slightly larger pipe diameter is inserted into the space volume C in the left clamp body 10 as viewed in FIG. When the pipe P1 is inserted upward from the opening position K as viewed in FIG. 2, the pipe insertion holding part piece 20 is expanded and deformed, and the opening size of the opening position K is increased. If it continues to be inserted, the pipe P1 comes into contact with the pipe support part piece 30, and the pipe support part piece 30 elastically deforms in a state of coming into contact with the reaction force support part 12 and the holding angle for receiving the pipe P1 changes. To go. When the pipe P1 is inserted into the space volume C until the holding angle does not change, the pipe insertion holding part piece 20 returns to the free state, and is near the lower side of the pipe P1 as seen in FIG. And support. The pipe P1 is held between the pipe insertion holding part piece 20 and the pipe support part 30 by the above usage.

Next, a mode in which the pipe P2 having a smaller pipe diameter than the pipe P1 is inserted into the space volume C in the right clamp body 10 as viewed in FIG. When the pipe P2 is inserted upward from the opening position K as viewed in FIG. 2, the pipe insertion holding portion piece 20 is expanded and deformed, and the opening size of the opening position K is increased. However, since the pipe diameter of the pipe P2 is smaller than that of the pipe P1, the opening size is smaller than that of the pipe P1 described above. If it continues to be inserted, the pipe P1 comes into contact with the pipe support part piece 30, and the pipe support part piece 30 is elastically deformed in a state of coming into contact with the reaction force support part 12, and the holding angle for receiving the pipe changes. Go. However, also in this case, since the pipe P2 has a smaller pipe diameter than the pipe P1, the holding angle is larger than that of the pipe P1 described above. When the pipe P2 is continuously inserted and the pipe P2 fits in the space volume C, the pipe insertion holding part piece 20 returns to the free state and receives and supports the vicinity of the lower side of the pipe P2 as seen in FIG. To do. The pipe P2 is held between the pipe insertion holding part piece 20 and the pipe support part 30 by the above usage.
From the above description, the pipe clamp 1 according to the present embodiment can cope with the type of pipe even when a clamp body having the same size and shape is used, and reliably holds the pipe. Can do.

The present invention is not limited to the configuration of the above embodiment, and can be implemented in various other forms.
For example, in the above embodiment, the configuration in which the clamp body 10 is provided in two places on the pipe clamp 1 is shown, but the present invention is not limited to this configuration. That is, it is good also as a structure by which the clamp main body 10 was provided in multiple places of 1 place or 3 places or more. Specifically, the pipe clamp 1 shown in FIG. 1 may have a configuration in which the mounting portion 70 is symmetrical and two clamp bodies 10 are provided in the left-right direction as viewed in FIG. In this case, the pipe clamp 1 can hold four pipes.
Moreover, in the said embodiment, although the clamp main body 10 provided in the left-right direction seeing FIG. 1 showed the structure made into the same magnitude | size shape, it is not limited to this structure. For example, the width in the width direction of the right clamp body 10 as viewed in FIG. 1 can be reduced. In this case, when a pipe having a slightly larger pipe diameter is accommodated, the left clamp body 10 as viewed in FIG. 1 is used, and when a pipe having a slightly smaller pipe diameter is accommodated, the right width as viewed in FIG. Can be accommodated by the clamp body 10 having a narrower width.
In the above embodiment, the inverted U-shaped portion 32 and the reaction force support portion 12 are arranged in contact with each other. However, even if both are not arranged in contact, the configuration is shown. good.

It is a perspective view which shows the pipe clamp which concerns on this embodiment. It is a front view which shows the pipe clamp which concerns on this embodiment. It is a front view which shows the state in which the pipe was accommodated in the pipe clamp. It is a front view which shows the conventional pipe clamp.
