Description

  The present invention relates to an improvement of a holder used to support a tube through which a fluid flows with respect to a support column.

  The irrigation tube held by the fixed part combined through the support part and the connecting part is fitted to the ground by inserting the support part from the side part into the support part having a U-shaped horizontal section. There is a support member disclosed in Patent Document 1 as a member that is held in a state where there is a gap between the two.

  In the thing of this patent document 1, since the load by the side of an irrigation tube is supported by the support | pillar attachment part fitted on a support | pillar as mentioned above, the vertical dimension of a support | pillar attachment part is hard to shorten. That is, when the vertical dimension of the column attachment portion is shortened, the column attachment portion is easily detached from the column. The longer the vertical dimension of the column mounting part, the more difficult it is to come off from the column, but in such a case, the resistance when the column is inserted into the column mounting part increases, so the mounting work to the column, and further from the column Removal work is not easy. In addition, the support member of the irrigation tube is increased in size.

Japanese Patent No. 4617193 (see paragraph number 0078, FIG. 9)

  The main problem to be solved by the present invention is that the holder used to support the tube on the support column can be easily detached from the support column and can be detached from the support column even if the load on the tube side is large. Further, it is possible to rationally reduce the size.

In order to achieve the above object, in the present invention, the tube holder is clamped to receive the strut from the side thereof while elastically expanding the inlet,
A holding portion for holding a tube on the side of the support;
And a support portion that is pressed against the column by a load generated when the fluid flows into the tube.

  The holder can be attached to the support in a manner that can be adjusted after attaching the attachment position along the length of the support. Since the load on the tube side held by the holding part can be received by pressing the support part against the support column and the load applied to the clamping part can be reduced, the vertical dimension of the clamping part can be made as small as possible. The tube can be stably held at a desired height position on the side of the column. This makes it easier to elastically deform the clamp part when the post is received in the clamp part and the holder is attached to the post, and when the post is removed from the clamp part and the holder is removed from the post. Attachment and removal operations are easy. Further, the holder can be rationally downsized.

  It is one of preferred embodiments of the present invention that the support portion is provided above the clamp portion and on the side opposite to the holding portion with the support column interposed therebetween. Moreover, it is set as one of the preferable aspects of this invention that the said support part is provided under the said clamp part and the same side as the said holding | maintenance part. In addition, it is one of preferred embodiments of the present invention that the pressing direction of the support portion with respect to the support column is set to intersect with the receiving direction of the support column with respect to the clamp portion. When it does in this way, the said support part does not become obstructive in the said attachment and detachment operation of the holder with respect to the said support | pillar.

  The support portion may be provided with a non-slip portion having a high frictional resistance, and the anti-slip portion may be in contact with the support column. In this case, it is possible to increase the frictional resistance between the support portion and the support column and hold the tube more stably on the side of the support column.

  The holding portion includes a base and a pair of arm portions that form a holding space of the tube between the base and the arm in contact with the tube while being elastically deformed by the tube at the time of fluid inflow. This is one of the preferred embodiments of the present invention. In this case, it is considered as one of preferred embodiments of the present invention that the base is provided with a recess for storing a part of the tube at the time of fluid inflow. In this case, when the tube expands due to the inflow of fluid, the pair of arms can be pressed against the tube while elastically deforming the pair of arms on the side opposite to the base while part of the tube is placed in the recess. The tube that expands in this way can be expanded without being distorted in a state where the tube is positioned at a predetermined position in the holding portion.

  Further, the tube is swelled by inflow of fluid so as to be changed from a flat shape to a cylindrical shape, and the base portion is provided on both sides of the recess with an edge of the tube at the time of the flat shape. One of the preferred embodiments of the present invention is to provide a contact portion for the portion. In this case, it is possible to hold the flat tube before inflating as described above in the holding portion without tilting, and when this tube is provided with a small hole for watering, this tube When the swells in the holding portion, the small hole can be positioned without deviation in a desired direction.

  According to the present invention, the holder used to support the tube on the support column has a structure that can be easily attached to and detached from the support column, so that it does not come off from the support column even if the load on the tube side is large. In addition, it can be rationally downsized.

  Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The holder S according to this embodiment is used for supporting the tube through which the fluid flows with respect to the support column P.

  In the illustrated example, the holder S has a column C (also referred to as a hose) used for sprinkling water necessary for plant growth in a field or a medium, and a column that is erected on the field or the like. Using P, it is suitable to be used for supporting at a predetermined height position. A plurality of struts P are set up with a space between the struts P adjacent to the field and the like, and a holder S is attached to each strut P with a clamp portion 1 which will be described later. The tube C is held by the holding unit 2, whereby the tube C can be arranged in the field or the like with a distance between the tube C and the ground.

  In the example shown in the figure, the tube C swells due to the inflow of fluid so as to change from a flat shape to a cylindrical shape. That is, in the illustrated example, the tube C has flexibility, and in a state where the water W is not fed, the cross section in the direction perpendicular to the length direction is flat (see FIGS. 4 and 6). When W is fed, it gradually expands, and finally the cross section is circular (see FIGS. 5 and 7). In the illustrated example, the tube C is provided with a plurality of small holes (not shown), and the water spray is performed by the small holes (see FIG. 5).

  The holder S includes a clamp part 1, a holding part 2, and a support part 3 provided integrally. Typically, the holder S is provided as a molded article made of a plastic material.

  The clamp portion 1 is configured to receive the support column P from the side portion Pa (side orthogonal to the length direction of the support column P) while elastically expanding the entrance 10. In the illustrated example, the clamp portion 1 is provided with a notch extending between the upper end and the lower end on the side portion of the cylindrical body having both the upper end and the lower end opened. It has become the mode. The clamp section 1 has a horizontal cross section whose internal shape follows the circular horizontal cross section of the column P. A plurality of engaging protrusions 12 are provided in the clamp portion 1 so that the width of the entrance 10 is narrower than the back side 11. The engagement protrusion 12 is formed by a protrusion that continues in a direction around the center of the circle. The engaging protrusions 12 are formed at five positions on both sides of the entrance 10 with a space between the engaging protrusions 12 adjacent in the vertical direction. Each engagement protrusion 12 has a top portion 12a on the entrance 10 side, and a portion located outside the entrance 10 with respect to the top portion 12a is an inclined portion 12b (see FIGS. 10 and 11).

  When the side axis Pa of the support column P is pressed against the entrance 10 so that the central axis x (see FIG. 8) of the clamp unit 1 is along the length direction of the support column P, the inclined portion 12b acts. The entrance 10 of the clamp part 1 is elastically expanded, and the acceptance of the support P into the clamp part 1 is allowed. When the diameter position of the support P exceeds the top 12a, the elastic return of the clamp part 1 is started. When the column P is completely received in the clamp part 1, the elastic return of the clamp part 1 is completed. Thus, the holder S can be attached to the support P in a manner that can be adjusted after the attachment position along the length direction of the support P is attached.

  In the illustrated example, the clamp portion 1 has a back portion 13 positioned on the opposite side of the entrance 10 and left and right side portions 14 and 14 positioned between the back portion 13 and the entrance 10. In one of the left and right side portions 14, 14, in the illustrated example, a bulging portion 15 that protrudes in the horizontal direction is formed on the outer side of the side portion 14 that is located on the left side with the formation side of the entrance 10 as the front. ing. The bulging portion 15 has a top portion 15a, a lower inclined surface 15b, and an upper inclined surface 15c that are positioned at the middle in the vertical direction of the clamp portion 1, and the left and right sides of the clamp portion 1 at the position of the top portion 15a. It has a shape that maximizes its dimensions.

  The holding portion 2 is configured to hold the tube C on the side of the support column P. In this embodiment, the holding portion 2 forms a holding space 22 of the tube C between the base portion 20 and the base portion 20 and is elastically deformed by the tube C at the time of fluid inflow. And a pair of arm portions 21, 21 in contact with the tube C.

  In the illustrated example, the holding portion 2 is formed on the first arm 4 extending in the horizontal direction with one end 40 integrally connected to the top portion 15a of the bulging portion 15 of the clamp portion 1. In the illustrated example, the central axis y of the first arm 4 and the center x ′ of the clamp portion 1 are substantially located on an imaginary straight line (see FIG. 10). On the other hand, the central axis y of the first arm 4 and the central axis x of the clamp part 1 are on the central axis y of the first arm 4 and closer to the protruding side of the first arm 4 than the central axis x of the clamp part 1. The crossing is performed with an angle slightly smaller than 90 degrees (87.5 degrees in the illustrated example) (see FIG. 8). In the illustrated example, when the holder S is attached to the support column P with the clamp portion 1 as described above, the center axis x is slightly inclined with respect to the clamp portion 1 so as not to coincide with the center axis of the support column P. By applying a force, the clamp portion 1 is prevented from freely moving downward using the support column P as a guide due to the frictional force applied between the clamp unit 1 and the support column P. In the state of being attached to the column P, if the central axis x of the clamp part 1 is made to coincide with the central axis of the column P, the holder S can be slid to a desired position using the column P as a guide. In the case where the support P is standing slightly inclined like the support of a dome-shaped greenhouse, the first arm 4 that intersects the clamp part 1 at an angle slightly smaller than 90 degrees as described above is It can be arranged so as to protrude from the support column P substantially horizontally.

  The holding portion 2 is formed between a position in the middle of the protruding direction of the first arm 4 and the protruding end 41. The base portion 20 is positioned below the upper edge of the first arm 4 and above the lower edge of the first arm 4 between the one end 40 of the first arm 4 and the location where the holding portion 2 is formed. And a virtual second horizontal line L2 positioned between the first horizontal line L1 and the lower edge of the first arm 4 (see FIG. 8). The base 20 has a rib shape that continues along the central axis y of the first arm 4 (see FIG. 10), and comes into linear contact with the tube C to be held. The arm portions 21 are respectively formed on both sides of a virtual vertical line L3 passing through a position in the middle in the length direction of the base portion 20 (see FIG. 8). The distance between one upper end of the pair of arm portions 21 and 21 and the virtual vertical line L3 is equal to the distance between the other upper end of the pair of arm portions 21 and 21 and the virtual vertical line L3. It has become. Each of the pair of arm portions 21 and 21 protrudes obliquely from the first arm 4 so as to approach the virtual vertical line L3 toward the upper end 21a. One of the pair of arm portions 21, 21 protrudes upward from a middle position in the length direction of the first arm 4, and the other of the pair of arm portions 21, 21 protrudes upward from the protrusion end 41 of the first arm 4. It sticks out.

  In the example shown in the drawing, the distance between the upper ends 21a of the pair of arm portions 21 and 21 is smaller than the width of the flat tube C and the diameter of the swelled tube C. On the other hand, the distance between the roots of the pair of arm portions 21 and 21 is substantially equal to the width of the flat tube C.

  Thus, in this embodiment, typically, the tube C is placed in the holding space 22 while elastically deforming the arm portion 21 so as to increase the distance between the pair of arm portions 21, 21. It receives from the direction orthogonal to the length direction. And in the said holding | maintenance space 22, the flat tube C before bulging as mentioned above and the tube C of the swelled state can each be hold | maintained stably.

  In this embodiment, the base 20 is provided with a recess 20a for accommodating a part of the tube C when the fluid flows in. In the illustrated example, the base portion 20 includes a recess 20a that follows the outer shape of the tube C when the fluid flows in. In the example shown in the drawing, a position of the base 20 that is positioned below one upper end 21a of the pair of arm portions 21 and 21 and a position that is positioned below the other upper end 21a of the pair of arm portions 21 and 21 are shown. In the meantime, the recess 20a is formed. The recess 20a is optimally arc-shaped following the outer shape of the tube C at the time of fluid inflow. However, the tube C accommodates a part of the tube C at the time of fluid inflow so that the tube C is not misaligned. Any shape that can be held by the holding unit 2 is not limited to the illustrated one.

  Thereby, in this embodiment, when the tube C expands due to the inflow of fluid, the pair of arm portions 21 on the side opposite to the base portion 20 while the part of the tube C is stored in the recess 20a. 21 can be pressed against the tube C while being elastically deformed, and the tube C thus swelled is positioned at a predetermined position in the holding portion 2 and is swelled without giving a distortion or the like that deforms the small hole. It is possible.

  Further, in this embodiment, the base 20 is provided on both sides of the recess 20a with an edge C ′ (in the flat shape) along the length direction of the tube C in the flat shape. The contact part 20b with respect to the bending | flexion or curved location side in the tube C) is provided. In the illustrated example, both sides of the recess 20a in the base 20 function as the contact portion 20b (see FIG. 6). Thereby, in this embodiment, the flat tube C before being swelled as described above in the holding part 2 can be held without tilting, so that the tube C swells in the holding part 2. At this time, the small holes for watering provided in the tube C can be positioned without deviation in a desired direction.

  The support portion 3 is configured to be pressed against the support column P by a load generated when the fluid flows into the tube C.

  In the example shown in the figure, the support part 3 is connected to the bulging part 15 at one end on the back side of the clamp part 1, on the upper end of the clamp part 1, and at the center of the clamp part 1. The protruding end 50 of the second arm 5 that extends obliquely so as to position the protruding end 41 on the opposite side of the protruding side of the first arm 4 across the axis x is provided.

  That is, the support part 3 is provided above the clamp part 1 and on the side opposite to the holding part 2 with the support P interposed therebetween.

  Further, the pressing direction f1 of the support portion 3 against the support column P is set to be a direction intersecting with the receiving direction f2 of the support column P to the clamp unit 1, that is, an orthogonal direction in the illustrated example ( (See FIG. 10).

  In the illustrated example, the front surface 51 of the second arm 5 facing the entrance 10 side of the clamp portion 1 is located at substantially the same position as the inner back portion of the clamp portion 1 (see FIG. 10). The support portion 3 has an axial shape that protrudes from the protruding end 50 of the second arm 5 toward the entrance 10 of the clamp portion 1. The support portion 3 is located outward from the inner surface of the side portion 14 on the side opposite to the protruding side of the first arm 4 of the clamp portion 1 (see FIG. 10). As a result, the support portion 3 is pressed against the side portion Pa on the side opposite to the protruding side of the first arm 4 in the support column P by the load on the tube C side above the clamp portion 1. Further, the protruding direction of the support portion 3 is parallel to the receiving direction f1 of the support P to the clamp portion 1, and the support portion 3 is positioned more laterally than the entrance 10 of the clamp portion 1 in a plan view. Thus, the support portion 3 does not prevent the support P 3 from receiving the column P into the clamp portion 1.

  According to such a configuration, first, the load on the tube C side held by the holding portion 2 can be received by pressing the support portion 3 against the support P, and the load applied to the clamp portion 1 can be reduced. Even if the vertical dimension of the clamp portion 1 is made as small as possible, the tube C can be stably held at a desired height position on the side of the column P. Thus, when the support P is received by the clamp 1 and the holder S is attached to the support P, and when the support P is removed from the clamp 1 and the support S is removed from the support P, the clamp 1 is elastic. It can be easily deformed, and such attachment and removal operations are facilitated. Second, the holder S can be rationally downsized. Thirdly, the support portion 3 does not get in the way in the attaching and detaching operations.

  In the illustrated example, the support portion 3 includes a non-slip portion 30 having a high frictional resistance, and is in contact with the support column P with the non-slip portion 30. Specifically, in the illustrated example, the support portion 3 includes a core portion 31 and a sleeve-like anti-slip portion 30 that passes through the core portion 31 inward and is fitted to the outside of the core portion 31. Yes. In such a case, the friction resistance between the support portion 3 and the support column P can be increased, and the tube C can be held more stably on the side of the support column P. In the illustrated example, the anti-slip portion 30 is made of rubber or plastic with rubber-like elasticity, and has a high frictional resistance. Although illustration is omitted, the surface of the support portion 3 may be roughened, or knurled or the like may be provided on the surface to increase the frictional resistance of the support portion 3.

  FIG. 14 shows an example (second example) in which the support part 3 is provided below the clamp part 1 and on the same side as the holding part 2. In this example, the support part 3 has one end integrally connected to the bulging part 15 on the back side of the clamp part 1, and is below the lower end of the clamp part 1. It is provided at the protruding end of the second arm 5 that extends downward so that the protruding end is positioned on the protruding side of the first arm 4 across x. Even in this second example, the pressing direction of the support portion 3 against the support column P is set to intersect the receiving direction of the support column P with respect to the clamp unit 1. Therefore, even in this second example, first, the load on the tube C side held by the holding part 2 can be received by pressing the support part 3 against the support P, and the load applied to the clamp part 1 can be received. Since it can reduce, the tube C can be stably hold | maintained in the desired height position in the side of the support | pillar P even if the vertical dimension of the clamp part 1 is made as small as possible. Thus, when the support P is received by the clamp 1 and the holder S is attached to the support P, and when the support P is removed from the clamp 1 and the support S is removed from the support P, the clamp 1 is elastic. It can be easily deformed, and such attachment and removal operations are facilitated. Second, the holder S can be rationally downsized. Thirdly, the support portion 3 does not get in the way in the attaching and detaching operations. The rest of the configuration of the second example is substantially the same as that of the first example, and a description thereof will be omitted.

  FIG. 15 shows an example (third example) in which the holding tube 2 can hold the flat tube C before being swelled as described above so that the width direction thereof is along the vertical direction. That is, in this third example, the base portion 20 constituting the holding portion 2 is vertically oriented, and one of the pair of arm portions 21, 21 protrudes obliquely downward from the upper end of the base portion 20, The other of the pair of arm portions 21, 21 protrudes obliquely upward from the lower end of the base portion 20. Since the remaining configuration of the third example is substantially the same as that of the first example, description thereof is omitted.

  Of course, the present invention is not limited to the embodiments described above, but includes all embodiments that can achieve the object of the present invention.
