Description

  The present invention relates to an apparatus for raising a fruit-cultivating shelf, and more particularly to a hand-held apparatus for raising a fruit-cultivating shelf that can push up the main branches and shelves of hanging fruit trees to their original positions.

  More specifically, the present invention relates to a push-up device that can be detachably attached to a slide pole that inserts a slide pipe into a fixed pipe and pushes up the shelf using a rack, a pinion mechanism, and a handle that operates the rack and pinion mechanism.

In pear gardens and vineyards that are cultivated using shelves, the main branches and shelves hang down due to the weight of fruits or the weight of snow in the winter season. Therefore, at the time of harvesting, the main branches and shelves must be pushed up to their original positions in order to increase the efficiency of the harvesting operation.
If you can't bear the weight of snow, branches can break or your house can collapse.

A method of using a jack as a device for pushing up the shelf to the original position is known.
Conventionally, a push-up rod such as a pipe or wood is interposed at the upper end of the jack. However, the jack can be placed on a carriage, and the place where it can be used is limited.

  Focusing on the above, the present inventor previously proposed Utility Model Registration No. 3151996.

Utility Model Registration No. 3151996

The device described in the above publication is a device previously proposed by the applicant of the present application, and the present device has been made with the aim of improving it.
That is, in an orchard with cultivation shelves, if the main branches and shelves that have been lowered by weight are not pushed up and returned to their original positions, operations such as fruit picking and pesticide spraying will be hindered.
In the case of mowing, etc., it is inevitable because there is a risk of damaging an important main branch with a farm tool, hitting the head, or hanging on the neck.
Conventionally, to lift a shelf, the main branch is lifted using the lifting rod, and then the deflection of the suspension line tied to the main branch is corrected, and again, several people need to fix the suspension line to the shelf. It was.
In addition, the invention described in the above publication is such that a jack is placed on the carriage, and the push-up bar placed on the main branch or shelf is pushed up by the jack, so that the weight is heavy and the carriage is used. Therefore, there are restrictions on the place of movement, and it is difficult to carry around.

  The present invention has been made for the purpose of providing a handy push-up device that is lightweight regardless of the location, with a simple configuration that is detachable from the slide pole.

  In order to achieve the above object, the present invention is detachably attached to a slide pole composed of a fixed pipe and a slide pipe, and an annular body for preventing the slide pipe crowned at the upper end of the fixed pipe from falling. A gear box mounted on the annular body and incorporating a gear; a hole penetrating in the vertical direction of the gear box; a horseshoe-shaped support ring formed in the gear box and loosely fitted in the slide pipe; An elevating rod having a rack that is held in a vertical movement in the hole and meshing with the gear; a free support ring that is provided above the elevating rod, is regulated at a predetermined vertical angle, and is loosely fitted to the slide pipe; When the pinion that meshes with the rack, the feed lever that engages with the pinion tooth in response to the operation angle of the handle, and also when rotated to the uppermost position of the handle It is obtained by a push-up device fruit cultivation racks provided with a stopper for preventing the reverse rotation of the serial pinion.

More specifically, when the handle is rotated to the uppermost angle, the stopper is disengaged in response to the upward direction of the handle.
In addition, the free support ring provided at the upper end of the elevating rod by allowing only a vertical angle is provided by being shifted by 90 degrees or substantially 90 degrees with respect to the support ring placed on the annular body.

  The present invention is a push-up device that uses an extendable pole and is provided even between a fixed pipe and a slide pipe. The push-up device is detachable from the slide pole and has a simple structure. It is to provide a type of push-up device.

  Furthermore, the push-up device can be easily attached to and detached from the fixed pipe and slide pipe of the telescopic pole, and has the effect of facilitating handling.

The slope figure which showed one Example of this invention and made the handle a little horizontal. The front view which similarly shows one Example of this invention. The same side view. The figure which similarly shows the internal mechanism of a gear box. The front view which made the handle | steering-wheel the highest angle which shows one Example of this invention. The figure which similarly shows the internal mechanism of a gear box.

  The present invention attaches a push-up device between the fixed pipe and slide pipe of the telescopic pole, and the pinion engaged with the rack stored in the gear storage box is rotated clockwise by the feed lever interlocking with the handle. The basic principle is to move the scissors upward and push up the slide pipe connected to the lifting scissors. In addition, the above-mentioned connection is based on the fact that the free support ring is loosely attached to the slide pipe, the free support ring is tilted to generate a wedge action, and both are connected.

Hereinafter, the configuration of an embodiment will be described with reference to the drawings.
FIG. 1 is a perspective view of the entire pole lifter with a fruit cultivation shelf push-up device, and FIG. 2 is a front view showing a state in which the pole lifter is attached to a slide pole.
In these figures, P1 is a fixed pipe, P2 is a slide pipe that is slidably inserted into the fixed pipe P1, and P3 is an annular body that prevents the slide pipe from falling downward.
The annular body P3 has a stop function, for example, a coil spring, which allows the slide pipe to move upward but prevents it from dropping.

Reference numeral 1 denotes a gear box formed of a steel plate or cast iron, and has a guide hole 2 penetrating vertically. In this guide hole 2, a lifting / lowering rod 3 formed of a U-shaped steel is slidably inserted. The lifting / lowering rod 3 is provided with a rack 4 cut by a desired length. Further, the gear box 1 is formed with a support ring 5 to be placed on the annular body P3 in a horizontal manner.
A part of the support ring 5 on the left in the figure is cut out to have a horseshoe shape, and the slide pole P2 can be inserted from the cut out part. The gap size of the notch is set slightly larger than the diameter of the slide pole P2.

A free support ring 6 is attached to the upper end of the lifting / lowering rod 3 by rotating a notch 90 degrees (to the front in the figure) with respect to the support ring 5. The free support ring is tilted up and down by a predetermined angle by the pin 7. As a result, the free support ring 6 bites on the surface of the slide pipe P2 by a wedge action, so that the slide pipe P2 is reliably pushed up.
Reference numeral 8 denotes a handle. The handle 8 is divided into bifurcated ends as support bodies 81 and 82, and the gear box 1 is sandwiched between the support bodies 81 and 82. The lift 8 is pushed up by operating the handle 8 at a desired angle.
FIG. 3 is a side view of the pole lifter.
Next, a mechanism for performing the above operation will be described.

In FIG. 4, a pinion 10 that meshes with the rack 4 and is rotatably supported by the pin 9 is provided.
Further, the handle 8 is provided with a feed lever 11 in the vicinity of the pinion 10 having a protrusion 11B whose tip engages with a tooth portion of the pinion 10. The lever 11 is urged by a torsion spring 11A wound around the pin 12 so as to press the tip thereof toward the pinion 10 side.

A stopper 13 is rotatably supported by the pin 14 and has a convex portion 15 that engages with a tooth portion of the pinion 10 and prevents the pinion 10 from rotating counterclockwise.
A coil spring 16 acts to press the convex portion 15 toward the pinion.

Since the present invention is configured as described above, the slide pipe P2 can be moved up and down as follows.
When the handle 8 is leveled, the tip of the feed lever 11 is engaged with the teeth of the pinion 10. When the handle 8 is operated downward and rotated in this state, the tip of the feed lever 11 pushes the pinion 10 and rotates the pinion 10 clockwise as shown in FIG.
When the pinion 10 rotates in the clockwise direction, the lifting rod 3 with which the rack 4 is engaged rises on the pinion 10 and raises the slide pipe P2. The ascending range is determined by the rotation amount of the gear 10.
At this time, the free support ring is regulated at a predetermined angle at the upper end of the lifting / lowering rod 3 and attached to the pin 7, so that the support free ring 6 is inclined. Therefore, it couple | bonds with the slide pipe P2 by the wedge effect.

On the other hand, the convex portion 15 of the stopper 13 is in contact with the teeth of the pinion 10 by a spring 16 and acts to allow the pinion 10 to rotate clockwise and to prevent counterclockwise rotation.
When the pinion 10 rotates in the clockwise direction, the protrusion 15 of the stopper 13 is moderated, and the sound becomes ticking and comfortable.
After the handle 8 is rotated by a desired angle, the slide pipe P2 can be raised to a desired height by the elevating rod 3 if the handle 8 is returned to the initial position, for example, the horizontal position, or returned to a slightly higher angle and then rotated downward. .

After the slide pipe P2 reaches a desired height, the gear 10 tries to rotate counterclockwise by a load from above on the lifting / lowering rod 3, but the protrusion 15 of the stopper 13 prevents the rotation and the lifting / lowering rod 3 To prevent the descent of. Therefore, the slide pipe P2 coupled to the free support ring 6 can be held at a desired height.
Thus, the pole lifter can push up the shelf and the main branch to the original position.

Next, as shown in FIGS. 5 and 6, when the handle 8 is rotated to the uppermost angle, the feed lever 11 is detached from the teeth of the pinion 10, and the upper end of the feed lever 10 opposes the stopper 13 against the spring 16. Push up.
Then, as shown in FIG. 6, the convex portion 15 of the stopper 13 is detached from the teeth of the pinion 10, and the pinion 10 is in a free state.
Therefore, although the lifting / lowering rod 3 meshing with the pinion 10 falls, the pinion 10 is locked from dropping the slide pipe P2 at the end of the rack 4.
Note that the upper and lower portions of the rack 4 where the teeth are not cut have a stopper function to prevent the pinion 10 from rotating, so that the lifting / lowering rod 3 stops falling and the sliding pipe P2 falls.

A method of attaching to the slide pole will be described.
First, the support ring 5 is inserted into the slide pipe P2 from the left opening in the drawing, and is further placed on the annular body P3 at the upper end of the fixed pipe P1.
Next, the free support ring 6 is inserted into the slide pipe P2 in the open port on the front side of the drawing in the same manner as described above with the lifting rod 3 tilted.
The support ring 5 and the free support ring 6 can be easily attached to and detached from the slide pipe P2 because their openings are shifted by 90 degrees.
In addition, if it reverses this procedure, it can remove easily from the slide pipe P2.

As described above, since the present invention operates as described above with a simple configuration, a simple and handy lifting device can be provided.
In particular, the shelf can be pushed up with only a slide pole without using a carriage or a jack, so that it is very light.
It should be noted that the present invention is not limited to one embodiment, and various modifications are conceivable within the scope of the utility model registration request, and it should be understood that these modifications are also included.
