Description

TECHNICAL FIELD The present invention relates to a support, which is mainly used to support the branches of fruit trees.

In an orchard where fruits such as grapes and pears are cultivated, a plurality of wires are laid out in a grid pattern at suitable height positions in the field, and posts are erected at positions where each wire intersects. Fruit tree trellis cultivation is performed in which a so-called trellis is formed by cultivating the fruit trees, and the trellis of the fruit tree and the fruits produced on the branches are carried by the trellis. In such fruit trellis, the wire bends as the fruit grows and the height of the fruit trellis becomes lower overall, which adversely affects the work efficiency of bagging work or fruit picking work. Work is being carried out to extend each column and adjust the height of the shelf.

However, as the number of cultivation days increases, the branches and fruits grow and the weight of the branches and fruits applied to the support also increases, so the load required to extend the support was excessive. Therefore, Patent Literature 1, which will be described later, proposes the following lifting device.

FIG. 14 is a schematic diagram showing how the push-up device disclosed in Patent Document 1 is used. In the figure, 200 is a support. The strut 200 has a double tube structure having an outer tube 210 and an inner tube 220. An annular body 230 provided at one end of the outer tube 210 allows the inner tube 220 to move forward from the outer tube 210. Movement is permitted, but movement in the direction of retreating into the outer cylinder 210 is prohibited.

On the other hand, the push-up device 170 comprises a rectangular cylindrical main body 173 containing a pinion, and inside the main body 173 is a square bar-shaped lifting device provided with a rack 176 that meshes with the pinion on one side. A rod 175 is inserted therethrough. A lever 174 for rotating the pinion is pivotally supported on the main body 173 so as to intersect the lifting rod 175. By rotating the lever 174, the lifting rod 175 can be moved up and down. It has become. A second fixing ring 172 is provided at the tip of the lifting rod 175 to be detachably fitted and fixed to the inner cylinder 220 , and the main body 173 is detachably fitted to the annular body 230 of the outer cylinder 210 . A first locking ring 171 is provided for locking.

In such a push-up device 170, the lever 174 is operated to lower the lifting rod 175, and in this state, the first fixing ring 171 is externally fixed to the annular body 230 of the column 200 as shown in FIG. At the same time, the second fixing ring 172 is fitted and fixed to the inner cylinder 220, and then the lever 174 is operated to raise the lifting rod 175. As shown in FIG. Since the inner cylinder 220 extends as the lifting rod 175 rises, the operation of the lever 174 is stopped at the timing when the tip of the inner cylinder 220 reaches an appropriate height position. Then, the first fixing ring 171 is removed from the annular body 230 of the strut 200 and the second fixing ring 172 is removed from the inner cylinder 220 . The height of the shelf is adjusted by performing such an operation for each support 200 installed in the field. Although the mass of fruit tree branches and fruits is applied to the strut 200, in the push-up device 170, the inner cylinder 220 can be easily extended from the outer cylinder 210 by operating the lever 174. Therefore, it is possible to reduce the load required for the work of extending the strut.

Utility Model Registration No. 3206376

However, in the push-up device 170 as described above, the length of the lifting rod 175 is limited from the standpoint of ease of attachment and detachment to and from the strut 200 and ease of carrying. Since there is a limit to the size to which the inner cylinder 220 can be extended, in order to extend the inner cylinder 220 beyond the limit, the push-up device 170 is attached to the support 200 and the inner cylinder 220 is extended. After that, the push-up device 170 is removed from the post 200, the lifting rod 175 is lowered by operating the lever 174, and then the push-up device 170 is attached to the post 200 again. The work of attaching and detaching the push-up device 170 was complicated. In addition, such an operation must be performed for each of the plurality of struts 200, and the load required for the extension work of each strut 200 is further increased.

Further, as described above, the strut 200 is allowed to move in the direction in which the inner cylinder 220 advances from the outer cylinder 210 by the annular body 230, but is prohibited from moving in the direction to retreat into the outer cylinder 210. When the push-up device 170 is applied to the strut 200 having such a structure, there is no need to perform operations related to fixing the inner cylinder 220 and releasing the fixing of the inner cylinder 220 when extending the inner cylinder 220. However, when the push-up device 170 is applied to another strut that does not have such a structure, the inner cylinder 220 must be fixed and unlocked when the inner cylinder 220 is extended. For such other struts, the load required for the extension operation was further increased.

The present invention has been made in view of such circumstances, and it is possible to extend it longer without repeating the installation and removal work, and to reduce the load required for the extension work as much as possible. Provide support that can

A support according to the present invention will be described in detail based on the drawings.
The support described in the present embodiment is merely an example for explaining the gist of the present invention, and it goes without saying that the present invention includes modifications and alterations within the scope of the gist.

(First form for implementing the idea)
FIG. 1 is a side view showing a support according to the present invention. In the figure, 2 is a double tubular main body formed by inserting an inner cylinder 4 into an outer cylinder 3 of appropriate length so as to be able to move forward and backward. 2 is an enlarged cross-sectional view taken along line II-II of the support 1 shown in FIG. 1, and FIGS. 4 to 6 are front and side views of the outer cylinder 3 shown in FIG. 1, and FIGS. 7 to 9 are a front view, a side view and a plan view of the inner cylinder 4 shown in FIG.

As shown in FIGS. 1 and 4 to 6, the outer cylinder 3 constituting the main body 2 is erected at a substantially central position on the surface side of a flat plate-shaped base 6 that is brought into contact with the ground of the field. A plurality of spikes 61, 61, .

As shown in FIG. 6, the outer cylinder 3 has a rectangular tubular shape in a plan view. guide portions 33a, 33a for guiding the inner cylinder 4 by bending the inner cylinder 4 inward. As shown in FIG. 4, this opening 32 is formed in a groove-like shape over substantially the entire length of the outer cylinder 3 in parallel with the central axis of the outer cylinder 3. Therefore, the guide parts 33a, 33a 3 is provided in a rail shape over substantially the entire length thereof.

As the outer cylinder 3 having such a configuration, for example, a rail member for supporting a hanging door can be used. In this embodiment, a rectangular outer cylinder 3 is used, but the present invention is not limited to this, and it goes without saying that a circular outer cylinder may be used.

As shown in FIGS. 1 and 4 to 6, a cover member 8 having a hole with an inner diameter slightly larger than the outer diameter of the inner cylinder 4 is formed at the end of the outer cylinder 3 opposite to the base 6. is fixed. A plate-like pedestal portion 39 is fixed to a position near the lid member 8 on the peripheral surface of the outer cylinder 3 . A first engaging portion 31 having a through hole 31a for engaging the portion 71 is erected. A ring-shaped handle 9 is attached to the outer cylinder 3 in the middle in the longitudinal direction so that the user can hold the handle 9 to carry the support 1 .

Here, Zojirushi Chain Block YA-80 (manufactured by Zojirushi Chain Block Co., Ltd.), for example, can be used as the chain block 7 described above.

On the other hand, as shown in FIGS. 7 to 9, the inner cylinder 4 has a cylindrical shape and is longer than the outer cylinder 3 described above. A plate-like plate having a thickness smaller than the width of the opening 32 of the outer cylinder 3 is provided on the outer peripheral surface of the inner cylinder 4 and in the vicinity of one end of the inner cylinder 4 to be inserted into the outer cylinder 3 . The second engaging portion 42 is erected in parallel with the central axis of the inner cylinder 4, and the second engaging portion 42 has a through hole 42a for engaging the second hook portion 72 of the chain block 7. has been opened.

In this embodiment, the case where the inner cylinder 4 is formed into a cylindrical shape is shown, but the present invention is not limited to this, and it is needless to say that it may be formed into a prism shape.

In addition, on the outer peripheral surface of the inner cylinder 4 and between the one end of the inner cylinder 4 and the second engaging portion 42, there is provided a plate that is brought into sliding contact with the guide portions 33a, 33a of the outer cylinder 3 described above. A sliding contact portion 45 having a shape is fixed, and when the inner cylinder 4 inserted into the outer cylinder 3 advances and retreats, the sliding contact portion 45 of the inner cylinder 4 slides on the guide portions 33a, 33a of the outer cylinder 3. The contact prevents the inner cylinder 4 from rattling and prevents the outer peripheral surface of the inner cylinder 4 from wearing.

On the other hand, the other end of the inner cylinder 4 is provided with a support plate portion 5 for supporting branches of fruit trees and/or wires of fruit tree shelves. The support plate portion 5 is formed by bending both short side portions 52, 52 of a rectangular plate material to the same side so as to form an obtuse angle with respect to the bottom portion 51, and molding the support plate portion 5 into a plate shape when viewed from the front. At the center of the bottom portion 51 of the portion 5, a through hole 55 having an inner diameter at least equal to or larger than the inner diameter of the inner cylinder 4 and communicating with the inner cylinder 4 is opened. In addition, concave portions 53, 53 having appropriate shapes (semicircular shapes in the present embodiment) are provided at substantially the centers of the edges of the bent side portions 52, 52, respectively, and as will be described later, the wires of the fruit shelf are provided. are fitted into the recesses 53, 53 to allow the wire to escape.

As shown in FIG. 1, the inner cylinder 4 is inserted into the outer cylinder 3 so that the second engaging portion 42 of the inner cylinder 4 protrudes from the groove-shaped opening 32 of the outer cylinder 3, thereby A first engaging portion 31 provided in the vicinity of the end portion of the outer cylinder 3 opposite to the base portion 6 and a second engaging portion 42 provided in the vicinity of one end portion of the inner cylinder 4 to be inserted into the outer cylinder 3. They are arranged facing each other with a distance slightly shorter than the length of the outer cylinder 3 . The chain block 7 is interposed between the first engaging portion 31 and the second engaging portion 42, and the first hook portion 71 provided on the block body 70 of the chain block 7 engages the first engaging portion. A second hook portion 72 connected to the through hole 31 a of the portion 31 and to the tip portion of the chain 73 of the chain block 7 is engaged with the through hole 42 a of the second engaging portion 42 . A block body 70 of the chain block 7 incorporates a gear 70a around which the chain 73 is wound. be. By operating the lever 74 to wind up or unwind the chain 73, the distance between the first hook portion 71 and the second hook portion 72 can be reduced or restored.

FIG. 3 is an explanatory diagram illustrating a state in which the inner cylinder 4 of the support 1 shown in FIG. 1 is extended. In the figure, the parts corresponding to the parts shown in FIG. 1 are given the same numbers.

As shown in FIG. 1, in the support 1 according to the present invention, the full length of the support 1 is maximized when one end of the inner cylinder 4 inserted into the outer cylinder 3 is in contact with the base 6. It is a short initial state, and in this initial state, the distance between the first engaging portion 71 and the second engaging portion 72 is the greatest.

When the chain 73 is hoisted by operating the lever 74 of the chain block 7, the second engaging portion 42 engaged with the second hook portion 72 is lifted accordingly. When the inner cylinder 4 to which the joining portion 42 is fixed is extended from the outer cylinder 3 and the operation of the lever 74 is stopped, the extension of the inner cylinder 4 is stopped and held at that height position. Here, the chain block 7 is provided with a mechanism for preventing the chain 73 from unwinding.

The inner cylinder 4 can be extended from the outer cylinder 3 until the distance between the first engaging portion 31 and the second engaging portion 42 is reduced and the chain 73 cannot be hoisted, while the lever 74 Only by stopping the operation of , the extended inner cylinder 4 can be held at the height position. As a result, the load required for the extension work of the support 1 can be reduced as much as possible.

At this time, the one end side of the inner cylinder 4 is pulled outward from the second engaging portion 42 by the second hook portion 72 of the chain block 7 . A plate-shaped sliding contact portion 45 is fixed between the one end of the outer cylinder 3 and the second engaging portion 42, and both guides face the opening 32 opened over substantially the entire length of the outer cylinder 3. Since the portions 33a, 33a are provided, when the inner cylinder 4 extends, the sliding contact portion 45 of the inner cylinder 4 is brought into sliding contact with the guide portions 33a, 33a of the outer cylinder 3 (see FIG. 6 for both). Thus, the inner cylinder 4 is prevented from being loose, and the wear of the outer peripheral surface of the inner cylinder 4 is avoided.

10A and 10B are explanatory diagrams for explaining how the support 1 shown in FIG. 1 is used. In the drawings, the same numbers are given to the parts corresponding to the parts shown in FIGS.

As shown in FIG. 10, the fruit tree shelf T is constructed by extending a plurality of wires W, W, . . . there is In such a fruit tree shelf T, branches B may be supported at places where the vertical and horizontal wires W, W intersect. At this time, the support 1 is kept in its initial state.

Next, by operating the lever 74 of the chain block 7 as described above to wind up the chain 73 of the chain block 7, the second engaging portion 42 engaged with the second hook portion 72 is lifted, and the second engaging portion 42 is lifted. The inner cylinder 4 to which the engaging portion 42 is fixed is extended from the outer cylinder 3 and contacts the wires W, W crossing the bottom portion 51 of the support plate portion 5 and the branch B carried by both wires W, W. Let

At this time, the branch B is inserted between the bent side portions 52, 52 of the support plate portion 5, but the wire W supporting the branch B substantially parallel to the branch B is attached to both sides of the support plate portion 5 together with the branch B. Since it is inserted between the portions 52 , 52 , contact between the wire W and both side portions 52 , 52 of the support plate portion 5 is avoided. On the other hand, the other wire W that intersects with the wire W is inserted into the recesses 53, 53 provided in the side portions 52, 52, respectively. Contact with parts 52, 53 is avoided. In this manner, even when the wires W, W intersect, the wires W, W are prevented from coming into contact with the supporting dish portion 5 constituting the support 1, and the wires W, W are supported by the supporting dish portion 5. Damage is prevented.

Further, the lever 74 is operated to extend the inner cylinder 4 from the outer cylinder 3, and when the wires W, W and the branches B reach appropriate height positions, the operation of the lever 74 is stopped. When the operation of the lever 74 is stopped, the extension of the inner cylinder 4 is stopped and the inner cylinder 4 is held at that height position.

Fruits (not shown) are produced on the branches B of the fruit tree, and as they grow, the wires W, W, . This adversely affects work efficiency such as bagging work or fruit thinning work. Therefore, at an appropriate timing, the lever 74 of the chain block 7 is operated again to extend the inner cylinder 4 from the outer cylinder 3, and the wires W, W and branches B are adjusted to appropriate height positions.

In this way, even when the heights of the inner cylinder 4 and the support plate portion 5 are adjusted once and then the heights are adjusted again, it is only necessary to operate the lever 74 of the support 1 according to the present invention. Therefore, the load required for adjusting the height of the support 1 can be reduced as much as possible.

When the fruit harvesting period ends, the lever 74 is operated to store the inner cylinder 4 in the outer cylinder 3 until the above-described initial state is reached, and the handle 9 attached to the outer cylinder 3 is gripped to hold the support member. 1 is transported to the hangar and stored there. This allows the storage space to be kept as small as possible.

By the way, the support 1 according to the present invention can also be used as follows.

FIG. 11 is an explanatory diagram illustrating another mode of use of the support 1 shown in FIG. In the figure, the parts corresponding to the parts shown in FIG. 10 are given the same numbers, and the description thereof is omitted.

For example, when the height dimension of the branch B of the fruit tree is lower than the height dimension of the support 1 in the initial state, as described above, the support 1 is arranged between the ground of the field and the branch B, and the support plate It is very difficult to carry the branch B at the portion 5, and there is a possibility that the branch B may be damaged.

Therefore, in the support 1 according to the present invention, as shown in FIG. The inner cylinder 4 is extended until the support plate portion 5 reaches an appropriate height position above the branch B, and the operation of the lever 74 is stopped to hold the inner cylinder 4 at that height position. A hanging member R such as a rope is hung between the side portions 52, 52 of the support plate portion 5 and the branch B, and the length of the hanging member R is adjusted to adjust the height of the branch B appropriately. It is hoisted.

As a result, even if the height dimension of the branch B is lower than the height dimension of the support 1 in the initial state, the branch B can be easily adjusted to an appropriate height position without damaging the branch B. can be adjusted to

Although FIG. 11 shows a case where one hanging member R is used, the present invention is not limited to this, and a plurality of hanging members R, R, . . . may be used.
