DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a hose binding member for binding a plurality of hoses such as a hydraulic hose provided in a hydraulic construction machine.

[0002]

2. Description of the Related Art In general, in a hydraulic construction machine of this type, a large number of hydraulic hoses are piped. In particular, a large number of hoses are densely arranged near a control valve or a hydraulic pump composed of a plurality of valves. It is arranged as
These hoses need to be protected from damage due to contact with other members such as hydraulic equipment. In addition, the hose
Depending on the application, there are different types of hoses with different withstand pressure such as high pressure, medium pressure, low pressure, etc., or those showing various properties such as hose oscillating due to pump pulsation because it is connected to a pump, hoses with different properties It is desirable to take care to avoid mutual interference. Therefore, conventionally, hoses of the same nature have been bundled using a band or the like so as not to come into contact with other members or the like.However, when hoses are densely packed in a narrow space near the control valve or the hydraulic pump or the like. In such a case, as shown in FIG. 5, in this case, hoses having different properties (for example, a hose 7 for pilot pressure oil and a hose 8 for negative control pressure oil) are joined together using a band 9 as shown in FIG. Sometimes I had to bundle them.

[0003]

However, in the case where hoses having different properties are bundled using the above-described conventional band, if any of these hoses vibrates due to, for example, pump pulsation, the vibrations may be reduced. As a result, the band may be loosened and the hose and the band or the hoses may be rubbed against each other and the hose may be damaged. Therefore, it is suggested that the outer periphery of the hose be guarded with an elastic material such as rubber and then bound with a band. However, even in this case, it is necessary to increase the tightening force in the band to a certain extent so that the hose is not exposed to vibration or the like, so that the hose vibrates in this state. There is also a problem that the elastic material is not used because there is a case where the elastic material is deeply cut and broken. In this case, there is a problem to be solved by the present invention.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been created for the purpose of solving these problems. A hose binding member, wherein the hose binding member is formed with a through-hole for hose penetration therein, a connecting portion for detachably connecting the hose binding members to each other at an outer peripheral portion, and an outer peripheral portion. A cut from the portion to the through hole is formed, and a gap for fitting the hose from the outer peripheral portion to the through hole is formed by expanding the cut. By doing so, a plurality of hoses can be bound together by connecting the connecting portions of the hose binding members attached to each hose, but in this case, each hose is connected by a hose binding member. The hoses are protected and do not interfere with each other, so that hoses having different properties can be bound without any trouble. Moreover, since the hose binding member can be fitted into the through hole from the outer peripheral portion by expanding the cut, the hose binding member can be connected to the hose even when the hose is connected to another hydraulic device or the like. It is convenient because it can be easily mounted. In this case, the hose binding member has a coating member for elastically covering the hose incorporated into the inner periphery of the through-hole, and the coating member also has a notch for fitting the hose therein. The hose can be more reliably protected by the covering member, and the covering member can also be easily attached to the hose. Furthermore, by making the notches in such a configuration that the expansion is restricted in a state where the connecting portions of the hose binding members are connected, the inadvertent expansion of the cuts is caused by the connection of the hose binding members. There is an advantage that can be regulated. Further, the connecting portion formed on the outer peripheral portion of the hose binding member can be constituted by a connecting convex portion and a connecting concave portion which can be detachably fitted to each other. Further, in this structure, a cut is formed so as to pass through the connecting protrusion, and the expansion of the cut can be restricted by fitting the connecting protrusion into the connecting recess. Furthermore, by forming a connection concave portion on the outer peripheral surface portion opposite to the outer peripheral surface portion where the connecting convex portion through which the cut passes is formed, the opposite side portion which is bent when the cut is expanded is thinned by the connecting concave portion. It is easy to bend and has the advantage that the cut can be easily expanded.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a hose binding member attached to each of the hoses 2 to bind a plurality of hydraulic hoses 2 provided in a hydraulic construction machine. The hose binding member 1 is made of natural rubber, It is made of an elastic material such as synthetic rubber or synthetic resin, and has an outer shape of a quadrangular prism, and has a through hole 1a for hose penetration inside.

Reference numeral 3 denotes a cylindrical covering member incorporated in the inner periphery of the through hole 1a of the hose binding member 1. The covering member 3 is made of a rubber material such as natural rubber, synthetic rubber, or synthetic resin. The hose 2 is made of an elastic material and elastically covers the hose 2 fitted to the inner peripheral portion thereof. In the present embodiment, the hoses 2 are arranged side by side at intervals in the axial direction of the hose 2. The pair of hose binding members 1 and one covering member 3 that is commonly incorporated into the through holes 1a of the pair of hose binding members 1 constitute one set. Further, at both ends in the axial length direction of the covering member 3, a flange portion 3 a protruding toward the outer diameter side is formed, and the flange portion 3 a is locked to the hose binding member 1 so that the hose binding member of the covering member 3 is formed. The structure is such that it is prevented from falling out of the through hole 1a.

On the other hand, the hose bundling member 1 has a rectangular column shape as described above, and its outer peripheral surface is formed of four first, second, third, and fourth surfaces 1b, 1c, 1d, and 1e. Although formed, in the present embodiment, a connecting projection 1f protruding toward the outer diameter side is formed on the first and second surface portions 1b and 1c adjacent in the circumferential direction. In addition, a third,
A connection recess 1 detachably fitted to a connection protrusion 1f formed on another hose binding member 1 on the fourth surface portions 1d and 1e.
g is formed. Here, the connecting projection 1f is formed in a trapezoidal shape that becomes wider toward the protruding tip side, and the connecting concave portion 1g is formed in a trapezoidal groove (dovetail) shape that becomes wider toward the bottom of the groove. The connection recess 1g can be easily fitted by sliding the hose binding member 1, and the fitting is prevented from being inadvertently disengaged.

Further, the hose bundling member 1 and the covering member 3 extend from the protruding end of one connecting projection 1f of the hose bundling member 1 to the through hole 1a, and further continuously to the inner peripheral portion of the covering member 3. Are formed as straight cuts 1h and 3b. Then, as shown by a chain line in FIG.
By expanding the cuts 1h and 3b, the hose 2
Can be fitted into the inner peripheral portion of the covering member 3 from the outer peripheral side of the hose binding member 1. in this case,
The hose bundling member 1 is located on the opposite side to the first and second surface portions 1b and 1c where the connection protrusion 1f is formed and the third and fourth surface portions 1d and 1e where the connection recess 1g is formed as described above. Therefore, the portion on the opposite side that bends when the cut 1h is expanded is thinned by the connecting recess 1g and is easily bent, so that the cut 1h can be easily expanded.

The hose binding members 1 attached to the different hoses 2 slide-fit the connecting protrusions 1f and the connecting recesses 1g as described above to thereby form the first surface portion 1b or the second surface portion 1c. And the third surface portion 1d or the fourth surface portion 1e can be connected in any of the vertical and horizontal directions without any gaps where the surfaces are in contact with each other. In this case, the connection protrusions formed with the cuts 1h are provided. The notch 1h is formed by fitting the portion 1f into the connecting projection 1g.
The opening of the notch 1h can be prevented from being carelessly expanded.

Reference numeral 4 denotes a stop member provided with a concave portion 4a to be fitted into the connecting convex portion 1f.
By attaching the notch 1h to the one that is not connected to the connecting recess 1g with the connecting protrusion 1f formed with the notch 1h, the expansion of the notch 1f at the end position can be regulated.

In the construction as described above, the plurality of hoses 2 are bundled together by connecting the connecting convex portion 1f and the connecting concave portion 1g of the hose binding member 1 mounted on each hose 2 to each other. In this case, each of the hoses 2 is connected to the hose binding member 1.
The hose 2 is protected by the covering member 3 and does not interfere with each other. As a result, even when the hoses 2 with different properties are bound together, the hoses are not rubbed or the elastic material is broken as in the case of binding a plurality of hoses using a conventional band, A plurality of hoses 2 can be bound while each hose 2 is securely protected.

Further, the hose binding member 1 and the covering member 3 are formed with cuts 1h and 3b extending from the outer periphery of the hose binding member 1 to the inner periphery of the covering member 3, and the cuts 1h and 3b are expanded. By doing so, the hose 2 can be mounted from the outer peripheral side, so that the hose 2 can be easily bound even after the hose 2 is connected to the hydraulic pump 5, the control valve 6, or the like, which is convenient.

Further, a cut 1 of the hose binding member 1 is provided.
h is formed so as to pass through one of the connecting protrusions 1f, so that when connecting the hose binding members 1 together, the connecting protrusions 1f having the cuts 1h are fitted into the connecting recesses 1g. The expansion will be regulated by
There is an advantage that it is possible to prevent the notch 1h from being inadvertently expanded and detached from the hose 2, and that a member for regulating the expansion of the notch 1h is not separately required. In addition, as described above, for the end position that is not connected to the connection recess 1g by the connection protrusion 1f where the cut 1h is formed, the expansion of the cut 1h can be regulated by attaching the stopper member 4.

It should be noted that the present invention is not limited to the above-described embodiment, and the outer shape of the hose binding member may be various shapes such as a cylindrical shape, a hexagonal shape, etc., in addition to the square shape. However, the rectangular or hexagonal prism shape has an advantage that the hose 2 can be bound in an orderly state without any gap. Further, in the above-described embodiment, the connecting portion of the hose binding member is formed on all four surface portions, and is configured to be connectable in any of the vertical and horizontal directions. In this case, it may be formed on two surface portions located on opposite sides, and furthermore, an appropriate number can be formed corresponding to the outer shape of the hose binding member. Furthermore, in the above embodiment, the cut formed in the hose bundling member is formed at a portion passing through the connecting convex portion, and the connecting convex portion is fitted into the connecting concave portion to restrict the expansion of the cut. However, it is of course possible to form them at other parts.
