Description

[Technical Field]

[0001] The present invention relates to a holder for pruning shears, and more particularly to a holder for pruning shears that prevents rotation and longitudinal movement of the pruning shears, allowing for smooth cutting and can also be used as a push cutter. [Background technology]

[0002] Conventionally, after pruning garden hedges and other plants with pruning shears or secateurs, the pruned branches are further cut and either disposed of as garbage or turned into compost. Cutting a large amount of material takes time and is a physically demanding task for people with hand or finger disabilities and the elderly. Patent Document 1 describes a holder structured so that one handle of a pair of pruning shears is inserted into a tube attached to a plate as shown in Figure 12 of the present application, the plate is pressed against the ground with the foot, and the other handle is pushed down to use it as a push cutter. [Prior art documents]

[0003] [Patent Document 1] Utility Model Registration No. 3208828 Summary of the Invention [Problem to be solved by the invention]

[0004] The device described in Patent Document 1 is a jig that has the added function of inserting and holding one end of the handle of a pair of pruning shears into a cylindrical material. When this jig was manufactured and used in actual applications, the following problems were encountered. Pruning shears have two blades that are continuous and tightly pressed together, allowing for good cutting. However, if the handle rotates within the tubular material or moves longitudinally, the handle can become unstable and optimal blade contact cannot be maintained, making it impossible to cut. In particular, the sharpness of the blades deteriorates over time, but there is no way to restore this. In addition, the vertical setting of the cylinder was fixed, so the working height was almost fixed and cutting had to be done while squatting, making the work unstable, causing pain to the waist and knees, making the work unstable and unsafe, and tiring, making continuous work difficult. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention has the following configuration.

[0006] The first hedge shears holder disclosed here is a hedge shears holder characterized by comprising a handle mounting fixture for inserting and holding one side of the handle of the hedge shears, an upper support for supporting the handle mounting fixture, and when viewed from the back side of the handle mounting fixture on the side opposite to the direction in which the handle is inserted into the handle mounting fixture, the handle and the handle mounting fixture can both be rotated clockwise within the upper support to adjust the angle of the shears blades, and the handle and the handle mounting fixture can be fastened to the upper support with a fastener or the like to prevent both rotation and movement in the insertion direction of the handle and the handle mounting fixture.

[0007] The second hedge shears holder disclosed here is a hedge shears holder characterized by a lower support attached to the lower side of the upper support using a fulcrum shaft, an up-and-down rotating fulcrum shaft set that allows the upper support to rotate vertically relative to the lower support and that can fasten a handle mounting fixture to the upper support, and the lower support attached to an upper fixed base plate.

[0008] The third hedge shear holder disclosed here is a hedge shear holder characterized by a structure comprising an upper fixed base plate to which a lower support is attached, an upper cylindrical rotating shaft attached to the upper fixed base plate, a lower cylindrical rotating support cylinder into which the upper cylindrical rotating shaft is inserted and supported so that it can rotate freely, and a height-setting fastener that adjusts the height of the lower cylindrical rotating support cylinder and supports the upper cylindrical rotating shaft, and the end opposite the insertion side of the lower cylindrical rotating support cylinder is attached to a cylindrical mounting base plate, a wide cylindrical mounting base plate, a base plate with a chair, etc.

[0009] The fourth hedge shears holder disclosed here is a hedge shears holder characterized by a balancer mounting member attached to the other end of the handle mounting fixture, and a weight or spring attached to this balancer mounting member to balance the weight of the hedge shears.

[0010] The fifth hedge shears holder disclosed here is a cylindrical handle mounting fixture that uses a cylindrical member as the handle mounting fixture, or a hedge shears holder that is characterized by a split handle mounting fixture made by bending a plate shaped based on an unfolded view. [Effects of the Invention]

[0011] The pruning shears holder having the above-described configuration has the following advantages.

[0012] First, the effect of the disclosed hedge shears holder is that the handle, handle mounting fixture, and upper support are integrated and fastened together with a fastener, and the angle of the scissors blade can be adjusted by turning both the handle and handle mounting fixture clockwise, and then fastened to the upper support with the fastener at a position that provides the best cutting edge.Furthermore, in response to changes in the cutting edge due to aging, the scissors blade can be rotated left and right to adjust the sharpness and then fastened, thereby improving the sharpness of the scissors blade.

[0013] Furthermore, since the handle and handle mounting fixture are fastened to the upper support as a single unit using a fastener, there is no rotation or longitudinal movement of the handle, which results in the effect of being able to cut the material stably and safely.

[0014] Furthermore, the second effect of the disclosed hedge shears holder is that the upper and lower supports are fastened together with an up-and-down rotating fulcrum shaft set, which is made up of bolts, nuts, washers, etc., and the bolts and nuts have circular steps formed on them, so the upper support is fastened with the bolts and nuts, and washers such as cup springs are fitted into both or one of the stepped parts of the lower supports and fastened with nuts.However, because the structure allows the support and fastening to be supported in a state where it can rotate up and down, the handle can be rotated easily, and the arm can be hardly felt any weight when opening and closing the hedge shears, which results in less fatigue.

[0015] Furthermore, the effect of the third disclosed hedge shears holder is that the upper cylindrical rotating shaft is attached to an upper fixed base plate to which a lower support is attached, and is inserted into the lower cylindrical rotating support cylinder, the lower cylindrical rotating support cylinder is attached to a cylindrical mounting base, and the upper cylindrical rotating shaft is supported by a height-adjusting fastener that can adjust the height of the lower cylindrical rotating support cylinder.The structure, which is equipped with a cylindrical mounting base, a wide cylindrical mounting base, or a base with a chair, allows the scissors blade to be held stably, so there is no rotation or movement in the longitudinal direction of the handle, and the material to be cut can be cut stably and safely.In addition, the upper cylindrical rotating shaft is supported and can rotate by the height-adjusting fastener that adjusts the height of the lower cylindrical rotating support cylinder, so when it is necessary to stand up to work, the scissors blade would get in the way, but the scissors blade can easily rotate along with the upper cylindrical rotating shaft, so it does not get in the way and the user can stand up smoothly.

[0016] Furthermore, the effect of the fourth disclosed hedge shears holder is that it has a balancer mounting member attached to the other end of the handle mounting fixture with a fastening member, and a weight, spring, etc. attached to the balancer mounting member, so that when the handle of the hedge shears is pulled up to open the shears blades, the weight of the hedge shears is reduced by this structure, and since there is almost no need to use any extra force to pull up the handle, it can be pulled up more easily, which has the effect of reducing arm fatigue.

[0017] Furthermore, the fifth disclosed effect of the hedge shears holder is that the handle attachment fixture is a tubular member, which can be machined from a tubular material, making it easy to process and inexpensive. Furthermore, by cutting spring plate material, bending this spring plate material, and subjecting it to heat treatment to make a split handle attachment fixture, the part becomes springy and does not deform, and it is easy to process slits, elongated holes, etc. [Brief explanation of the drawings]

[0019] Some examples of the best mode of the present invention will be described below, but it is not intended that the present invention be limited to these examples. [Example]

[0020] Figures 1 and 2 show an embodiment of the present invention, an overall conceptual diagram of a pruning shears holder 1, Figure 2 shows a top view, and Figure 3 shows a partial cross-sectional view of the pruning shears holder 1. Figure 4 also shows the handle 3 of the pruning shears 2 attached to the handle mounting fixture 4, with the handle 3 inserted up to the stopper 17, and the handle 3, handle mounting fixture 4, and upper support fixture 5 all inserted with bolt 12a of the integrated fastener 12 and temporarily secured with R-shaped washer 12b and cap nut 12d. After that, when looking at the handle 3 from the back side of the handle mounting fixture 4, the handle 3, handle mounting fixture 4, and upper support fixture 5 can all be rotated clockwise to adjust the scissors blades and then fastened with the integrated fastener 12, which has the effect of holding the scissors blades stably and safely.

[0021] In addition, the partial cross section shown in Figure 4 shows that the knife is fastened by tilting it to the right at an angle 15 from the vertical line 14. When operating the knife, by adjusting the angle and pulling the handle 3 downward and to the left with the right hand, both blades press together continuously, allowing the knife to cut the object 16 without any gaps. In addition, to deal with changes in the cutting edge due to aging, loosening the bolt 12a of the integrated fastener 12, rotating the scissors blade to the right, and then tightening it again after adjustment will improve the sharpness of the blade.

[0022] The angle 15 shown in Figure 5a is a diagram of a state in which the knife is rotated clockwise from the vertical line 14, and the angle suitable for cutting is 5° to 35° to the right of the vertical line 14. When cutting, pulling down the handle 3 and applying force to the lower left so that both blades come into contact makes cutting easier. Furthermore, if the object to be cut 16 is held with the left hand so that it is not lifted at an angle by the cutting blade during cutting, it is possible to expect smoother cutting.

[0023] However, if the angle 15 is 45° or more, the cutting may become unstable and the cutting may not be possible even if the cutter is pulled down to the left because the cutter may get caught in the cutting edge portion, which is unsuitable.

[0024] Figures 4 and 5a show partial cross-sectional views of the handle 3, handle mounting fixture 4, and upper support 5 fastened together with an integrated fastener 12. The upper support 5 is made of spring material and is divided into roughly equal halves on the left and right by a vertical line 14. In the center of the upper part, for example, an R-shaped bent portion 13 is provided on the upper support 5, which is expected to reduce the fastening force when fastened with the integrated fastener 12 and at the same time make the fastening more stable. [Example]

[0025] The diagram shown in Figure 6 is a partial cross-sectional view of the upper support 5 and the lower support 6 fastened together with the vertical pivot fulcrum shaft set 19, and the stepped bolt 19a and stepped washer 19b have a circular step, which fastens the upper support 5 to the handle 3 and handle mounting fixture 4 at both end surfaces. The hole of the lower support 6 is made 0.1 to 1.0 mm larger than the step diameter to aid rotation, and a washer 19c or the like is inserted into the circular step portion to prevent overtightening and aid rotation.

[0026] In addition, a spacer 19d is inserted inside the hole of the upper support 5 to make tightening easier, making it easier to fix the handle 3 and handle mounting fixture 4 with the upper support 5, and a washer 19c is inserted to prevent the handle mounting fixture 4 from being fixed by overtightening the lower support 6. In addition, since the bolt moves along the elongated hole in the upper support 5, the bolt will move smoothly if the elongated hole is made 0.1 to 0.5 mm larger than the bolt diameter, and the handle 3 and handle mounting fixture 4 also have holes that are 0.1 to 0.5 mm larger than the bolt diameter 12a, which is expected to enable smooth cutting during assembly operations. [Example]

[0027] Figure 8 is a schematic perspective view including a parts diagram of the cylindrical handle mounting fixture 10, upper support 5, lower support 6, upper fixed base plate 7, upper cylindrical rotating shaft 20, lower cylindrical rotating support cylinder 21, etc. mounted on a cylindrical mounting base plate 24, a wide cylindrical mounting base plate 31, etc.

[0028] Figure 9 will be explained together with Figure 8, and is a schematic perspective view including the part where the hedge shears 2 and cylindrical handle mounting fixture 10 are attached to the chair-equipped base 23, and the lower support 6 is fastened to the upper support 5 with an up and down rotation fulcrum shaft set 19. The lower support 6 is fastened to the upper fixed base plate 7 with a fastener or the like so that it can be rotated or fixed, and is attached to the upper cylindrical rotating shaft 20 with a fastening member. This upper cylindrical rotating shaft 20 is inserted and supported so as to be rotatable, and is supported by a height-setting fastener 22 that is inserted into the lower cylindrical rotating support cylinder 21 and used to adjust the height, and the end opposite the insertion side is attached to the cylindrical mounting base 24, wide cylindrical mounting base 31, chair-equipped base 23, etc. with a fastening member.

[0029] With the above-mentioned structure, the working height can be easily changed and the worker can work while sitting on a chair, which prevents back and knee pain, reduces fatigue, and allows for safer and more stable work.In addition, when the worker stands up from the chair, the pruning shears 2 can be gently rotated together with the upper cylindrical rotating shaft 20 within the lower cylindrical rotating support cylinder 21 to prevent them from getting in the way, which is expected to further increase safety. [Example]

[0030] FIG. 10 is an overall conceptual diagram of a cylindrical handle mounting fixture 10 to which a coil spring balancer 25 is attached, and FIG. 11 is an overall conceptual diagram of a split handle mounting fixture 11 to which a tension spring balancer 26 is attached. The balancer mounting member 27 is attached to the other end of the handle mounting fixture 4 with a fastening member. This balancer mounting member 27 has a spring or weight attached to it, and when the pruning shears 2 are operated up and down to prune, the weight acting on the arm can be reduced by 8 to 100% by balancing it against the weight of the pruning shears 2, which has the effect of significantly reducing fatigue. [Example]

[0031] Figure 10 shows a cylindrical handle mounting fixture 10. The cylindrical handle mounting fixture 10 can be easily made using pipe material, and Figure 11 shows a split handle mounting fixture 11, which is made by punching or laser cutting a flat plate material based on the developed view to create the folded portion and slits on the insertion side of the handle 3, and then bending it into a cylindrical shape. This makes it easier to balance the position of the holes and elongated holes and to process the folded portion, and by applying heat treatment it can be made into a mounting fixture with excellent spring properties.

[0032] The split handle mounting fixture 11 is provided with folded-over parts and hooking parts, and after inserting the handle 3, it is fastened with a belt or the like using the folded-over parts, and at this time the slit processed parts 28 of the handle mounting fixture 4 and the upper slit 28 of the split handle mounting fixture 11 help to firmly fasten and fix the handle 3. By using a spring material such as SUS304 and tempering it, it has spring properties, is rust-resistant, and can be made thinner, making it easier to process. [Industrial Applicability]

[0033] The present invention can be used not only as pruning shears alone but also as a lightweight auxiliary agricultural implement by using the pruning shears together with a pruning shears holder, which can be used for cutting pruned branches, cutting radish leaves, cutting and reducing the weight of flowers and plants, and also for composting.
