Description

  The present invention relates to a gardening tool, and more particularly to a gardening basket.

  In a conventional gardening jar, when the shearing operation is performed at the shearing portion, the sheared object immediately falls. This is not a problem for the work done with a kite. However, for the work of shearing some specific things such as flowers and fruits, the shearing part is a part to be reserved, and therefore, there is a problem that the sheared material easily breaks when falling to the ground etc. simultaneously with the shearing. is there. In addition, since an operator must pick it up and place it at a target point, there are inconveniences and disadvantages in work.

For this reason, in the industry, an improved structure has been developed in which a holding structure is provided on the side surface of the shearing portion of the ridge and the object to be sheared is held and does not easily fall. For example, in Prior Document 1 (Patent Document 1: Japanese Patent Laid-Open No. 2000-188954), the invention of flower picking scissors provided with a catch blade on the side surface of the blade edge is disclosed in Prior Document 2 (Patent Document 2: Japanese Patent Laid-Open No. 9-9 No. 28188) and Prior Document 3 (Patent Document 3: Japanese Patent Application Laid-Open No. 9-9782) describe the inventions of the long branch eaves provided with clamping teeth on the side of the shear blade.
Japanese Patent Laid-Open No. 2000-188954 JP-A-9-28188 Japanese Patent Laid-Open No. 9-9782

  However, each of the clamping structures used in the above inventions is a structure in which an elastic member is directly attached to one side surface of the scissors blade. First, the object to be sheared is clamped by the clamping structure, and then the movable blade is used. Since this is a shearing method, the balance of holding the object to be sheared is poor, and the object to be sheared is likely to wobble when shearing with a movable blade and a fixed blade, and one side of the object to be sheared is lifted by a clamping structure There is a problem that it is difficult to receive the object to be sheared at the point where the movable blade and the fixed blade overlap, and it becomes difficult to obtain the sharpness of shear.

  In addition, such a structure in which the object to be sheared is sandwiched by the side surface of the movable blade has a drawback that a predetermined clamping force does not last long because a large moment is received as a reaction force at the time of shearing and there is an inherent problem with durability. .

  Accordingly, an object of the present invention is to provide a gardening basket that improves the clamping structure provided in the shearing portion, has durability that allows a favorable clamping force to be obtained continuously, and does not impair the shearing ability of the basket. is there.

  Therefore, in order to solve the above-mentioned problems, the present inventor has made a two-layer structure of the shearing structure fixed blade after intensive study, and sandwiched a contact member corresponding to the receiving side of the sandwich structure between the two layers, and the sandwich structure The shearing operation is performed by pressing the movable plate and the shearing blade of the shearing structure against the contact member, so that the durability of the clamping structure is improved and the sheared object is not hindered. Based on this finding, the present invention has been completed.

That is, according to the following invention, the above-described problems can be solved.
(1) A gardening jar capable of holding a sheared object after shearing,
A fixed shear section comprising a support plate having a two-layer structure, a fixed groove formed between the support plates having the two-layer structure, and an abutting member that is fitted in the fixed groove and places the object to be sheared;

A tooth portion that abuts against the abutting member at one end and sandwiches the object to be sheared, and a sandwiching portion that has an extending portion at the other end;
An elastic body that elastically pushes the toothed portion against the sheared object when the extending portion and the movable portion are provided elastically and the shearing blade is pressed against the sheared object or the contact member;
With
The gardening basket characterized in that the fixed shearing part, the movable shearing part, and the clamping part each have a shaft through hole and are pivotally supported by one pivot.

The present invention includes the following related inventions as specific embodiments thereof.
(2) a tubular body portion having a through hole inside and connected to the fixed shearing portion at one end;
A transmission member inserted through the through hole and having one end rotatably connected to the movable portion;
A control lever connected to the other end of the tube body and the other end of the transmission member, and moving the transmission member back and forth by a grasping operation;
And having
The movable portion is a substantially L-shaped plate body having an engagement edge portion;
The horticultural basket according to (1), wherein the clamping part has an engaging convex part that engages with the engaging edge part.

  According to the horticultural basket according to the present invention, a shearing structure that shears an object to be sheared at the same time without damaging the shearing ability of the shearing structure is provided, and a preferable clamping force is obtained and the clamping force is sustained. As a result, the work of shearing and collecting the object to be sheared in horticulture can be facilitated, and high durability of the shearing structure can be obtained.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of a horticultural basket according to an embodiment of the present invention. However, the present invention does not need to take the form of a high branch cutting ridge as shown in FIG. 1 as described below. For example, the present invention is applied to a cutting ridge, a pruning ridge, a garden ridge, a bonsai pod, a grape chopstick, a floret, etc. Since it is possible to provide a pinching structure characteristic of the invention, the invention is not limited to the following embodiment.

  The horticultural basket according to the present embodiment is roughly divided into a tube section 10, a transmission member 20, a control lever 30, a fixed shear section 40, a movable shear section 50, a sandwiching section 60, and an elastic body 70. Become. The movable shearing part 50 and the fixed shearing part 40 form a shearing structure, and the clamping part 60 and the fixed shearing part 40 form a sandwiching structure.

  However, among the above, the tube section 10, the transmission member 20, and the control lever 30 are structural requirements for performing the original functions that the high branch cutting rod according to the present embodiment generally has, and are included in the present invention. It is not essential.

  The tubular body portion 10 is a hollow tubular body having a predetermined length and having a through hole 11 formed therein. The transmission member 20 is a casing that is inserted into the through hole 11 of the tubular body portion 10 and has a predetermined length. The control lever 30 is connected to one end of the transmission member 20 at one end on the near side of the tubular body portion 10 and moves the transmission member 20 back and forth by a grasping operation. Along with this, the other end of the transmission member 20 also moves back and forth, and drives a movable shearing section described later.

  The fixed shearing portion 40 is a receiving side member that is commonly used for the shearing structure and the sandwiching structure, and is composed of support plates 41 and 42 having a two-layer structure, and an abutting member 43 sandwiched between the support plates. . The fixed shearing portion 40 is connected to the tubular body portion 10, and a fixing groove 44 is formed between the support plates 41 and 42 having a two-layer structure. The support plates 41 and 42 may be of a separation type through which the fixing groove 44 passes, or may be a concave section in which the fixing groove 44 stays at a predetermined depth, as long as the contact member 43 can be sandwiched therebetween. In the present embodiment, a two-sheet separation type is adopted, and the abutting member 43 sandwiched between them is fastened together with two bolts.

  FIG. 2 shows an exploded view of the garden hoe according to the present embodiment. The abutting member 43 receives the shearing blade 51 and the clamping unit 60 on the upper surface, shears the object to be sheared in part, and clamps the object to be sheared in the other part. The shape and material are not particularly limited, but it is preferable that the upper surface is formed of an elastic material such as a rubber that is concave and abuts against the shearing blade 51 and is elastic. Further, the contact member 43 having a substantially T-shaped cross section preferably has a leg portion sandwiched between the two-layer support plates 41 and 42 as described above. This is because if the abutting member 43 is provided offset to one side of one support plate, the balance of the shearing operation and the durability will be deteriorated in the prior art.

  The movable shearing part 50 is, for example, a substantially L-shaped plate, and includes a shearing blade 51 and a movable part 52 that forms a depression with the shearing blade 51. The shape of the movable portion 52 is not particularly limited, and may be a plate shape or a curved tube shape. However, in the present embodiment, the movable portion 52 is illustrated as a plate-like member because it is a high branch cutting rod.

  The shape of the shearing blade 51 such as a curvature and an attachment angle is determined so as to contact the contact member 43 of the fixed shearing portion 40. The movable part 52 is inserted into the fixed groove 44 of the fixed shearing part 40. Further, shaft through holes 45 and 53 are formed at corresponding positions in the fixed shearing portion 40 and the movable portion 52, and are pivotally attached to each other by a support shaft 54. Further, the end of the movable shearing portion 50 is connected to the transmission member 20 so as to be rotatable, and the movable shearing portion 50 rotates about the support shaft 54 by the back-and-forth movement of the transmission member 20.

  The clamping unit 60 is a member that presses the sheared object against the contact member 43 in conjunction with the movable shearing part 50 in order to prevent the sheared object after the shearing from falling. Since the clamping part 60 is also pivotally attached to the fixed shearing part 40 via the support shaft 54, the clamping part 60 has a shaft through hole 61 at a substantially intermediate position. The shape of the sandwiching portion 61 is not particularly limited, and may be a plate shape or a curved tube shape. However, since the sandwiching portion 60 is a member that is interlocked with the movable portion 52, the structure of both is made common from the viewpoint of simplifying the mechanism. preferable. Therefore, in the present embodiment, the clamping unit 60 is a plate-like member like the movable unit 52.

  The clamping unit 60 may be clamped between the two support plates 41 and 42 or may be brought into contact with the outside of one of the support plates. In addition, it is preferable from the viewpoint of the ability to hold the object to be sheared that the tooth portion 62 is provided on a surface which is one end of the sandwiching portion 60 and is in contact with the contact member 43.

  An extending portion 63 is formed at the other end of the sandwiching portion 60, and an elastic body 70 is provided between the extending portion 63 and the movable portion 52. As a result, when the shearing blade 51 of the movable shearing part 50 is strongly pressed against the contact member 43 and the object to be sheared is sheared, the tooth part 62 of the clamping part 60 pulled by the elastic body 70 also comes into contact with a predetermined pressure. It elastically contacts the member 43.

  Here, depending on the object of the object to be sheared, there is a case where it is not allowed to strongly hold it in a clamping part such as a flower bud. In such a case, a weak biasing force can be obtained by changing the elastic modulus of the elastic body 70 to a low one. The object to be sheared can be clamped with. On the contrary, when it is necessary to hold a heavy object such as fruit, the elastic body 70 has a high elastic modulus, so that it can be held with a strong urging force similar to the pressing force of the shearing blade 51. Become.

  As described above, the present invention is characterized in that the shearing blade 51 is first brought into contact with the object to be sheared, and the clamping unit 60 is brought into contact with the object to be sheared after the shearing is started. That is, in all of the conventional techniques, the object to be sheared by the sandwiching part is held prior to the shearing operation. There is a problem that a load is applied and the durability of the clamping mechanism is impaired.

  In addition, if the object to be sheared is fixedly held by the sandwiching part, the shearing blade is only allowed to swing down. The operation of making a preliminary cut before is difficult. Therefore, like the horticultural basket according to the present invention, only the shearing blade 51 is first brought into contact with the object to be sheared, and the clamping unit 60 comes into contact with the object to be sheared only when the shearing progresses to a halfway state before cutting off. Thus, one of the objects of the present invention is achieved without impairing the shearing ability of the shearing structure.

  On the other hand, when the shearing blade 51 is separated from the abutting member 43 by opening the control lever 30 or the like, it is necessary for the normal opening / closing operation to open the clamping unit 60 following this. For this reason, an engaging convex part 64 is provided in the clamping part 60, and this and the engaging edge part 55 provided in the movable part 52 are engaged appropriately.

  FIG. 3 is an explanatory diagram of the operation of the horticultural basket according to the present embodiment. In the initial state in which the tooth portion 63 and the contact member 43 are in contact, the extending portion 63 is in a lifted state, and both the engagement edge portion 55 and the engagement convex portion 64 are in contact at a high position. From this state, when the transmission member 20 is advanced in the direction indicated by the arrow and the shearing blade 51 is opened, the engagement end edge 55 is pushed down clockwise in the figure while being engaged with the engagement protrusion 64. . As a result, the tooth portion 62 rotates clockwise around the support shaft 54 and is detached from the contact member 43.

  When the shearing blade 51 is further rotated clockwise, the engagement convex portion 64 finally comes into contact with the front end edge portion 46 of the fixed shear portion 40 and is sandwiched between the engagement end edge portions 55. . This is the maximum opening angle of the movable shearing part 50 and the clamping part 60, and the rotation angle of both is limited.

  FIG. 4 is a front view showing a use state of the garden robe according to the present invention. The abutting member 43 and the movable shearing part 50 are sandwiched between the two-layered support plates 41 and 42 constituting the fixed shearing part 40. The holding portion 60 is attached to the outside of the support plate 41 by a support shaft (not shown). The shearing object A is sheared by opening and closing the shearing blade 51 and the abutting member 43. In this operation, the shearing blade 51 first abuts on the shearing object A, and further shearing is started. Comes into contact with the object A to be sheared, and thereafter, even if the shearing is completed, the tooth portion of the holding part 60 continues to hold the object to be sheared by the biasing force.

  For this reason, even after being sheared, the object to be sheared is held without falling from the garden robe, and the nipping is released only after the shearing blade 51 is opened. Therefore, the shearing object A after shearing is moved to the target position and the shearing blade 51 is opened, so that the recovery can be performed efficiently.

  The horticultural basket according to the present invention is capable of continuously holding an object to be sheared such as a flower bud or a fruit even after shearing. Since the characteristic part of the present invention is in the movable part and the shearing part of the cutting edge, in addition to the high branch cutting shear illustrated in the embodiment, as described above, a cutting shear, a pruning shear, a garden shear, a bonsai shear, a grape shearing shear, It can also be applied to flower buds.
