(Viewpoints)
In general, snow shovels that are widely available on the market are relatively large scooping surfaces made of lightweight synthetic resin molded products so that more snow can be scooped and thrown out by one scooping operation, and The mainstream is a wooden handle that extends from the center of the rear, but excavators with such a structure are heavy and contain a lot of moisture, even if there is no inconvenience when handling dry, relatively light snow. It is unsuitable for snowfall, and it imposes a heavy burden on people in snowy countries facing such scenes, especially for elderly people, women, children, etc. Met.

    These disadvantages are the structure in which a relatively long handle is attached, and the position and posture when gripping the handle are naturally determined by the structure, and the weight of snow taken on the scooping surface The principle of this works, and it must be lifted with a force much larger than the actual weight, so the burden on the operator is increased, and moreover, it tries to eliminate the occurrence of the action due to this inconvenient lever principle. If you try to scrape snow by gripping the handle part near the scooping surface, it will be a cramped work that bends your waist down so that you can reach your hands close to the ground. The handling burden was too large for the handling as it is.

(Conventional technology)
In order to deal with these problems of the prior art, for example, the “improved shovel” disclosed in Japanese Utility Model Laid-Open No. 03-108042, the “Tecosco” invention disclosed in Japanese Patent Laid-Open No. 61-28631, and Japanese Patent Laid-Open No. 60-129328 are disclosed. As shown in the “Structure of Scoop” invention, etc., several improved technologies have been developed and proposed one after another, all of which are gripped near the scooping surface of the excavator body and the handle. A fixed or foldable handle for use, or a handle with a leash, where the user lifts the handle near the scooping surface with little or no bending, It can be held, and the workability of snow-scraping can be increased as much as possible.

Further, as a method aiming at efficient snow removal work by a structure fundamentally different from the above, there is, for example, the “Branco Excavator” invention disclosed in Japanese Patent Laid-Open No. 63-103107, which is a ugly surface. A swingable handle is extended from the center of the rear edge of the handle. A grip is provided at the end opposite to the scooping surface of the handle. A suspension frame that is integrated with each other, and a handle that is provided with a gripping portion at the upper end is connected to the left and right center of the upper end of the suspension frame, and the user holds each handle with both hands. Gripping the scooping surface, with the bottom surface of the scooping surface in contact with the ground surface, and swinging it in the edge direction to allow snow removal work with little bending of the hips. So that it can be lifted so that the action of the lion does not work on snow Yes.

(Awareness of problems)
However, none of the proposals mentioned above are limited to structures that must be lifted with a force greater than the weight of the snow on the scooping surface plus the weight of the entire shovel. In order to make it easier to handle for elderly people and women and girls, it needs to be further improved, and the latter type of swing type is too complicated compared to a general excavator. In addition, the distance from the gripping part gripped by the left and right hands to the scooping surface is long, making it difficult to operate, and the weight of the excavator itself is inevitably increased, possibly reducing the work efficiency. This was a concern.

(Object of invention)
Therefore, the present invention provides an ideal snow shovel that ensures that the conventional shovel, in particular, the snow shovel remains in the above-described situation, and can still achieve the efficiency of snow-scraping work. I have questioned the fact that it has not been done, and decided that it would be impossible to realize an excavator represented by a snow excavator that can solve these problems all at once. As a result of repeated trial and error over many years, and many trial productions and experiments, this time we finally came to Sakai and succeeded in realizing a shovel with a new structure and a swing handle with a new structure for it. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As will be clearly understood from the embodiments representing the present invention shown in the drawings, the excavator included in the present invention basically includes the following configuration.
That is, a scooping surface of an appropriate size formed on the right and left side edges and the rear side edge where the front end is a straight intake edge, and the three sides of the flat surface following the back are appropriately warped upward, and the scooping surface The excavator body is formed by a handle extending rearward from approximately the center of the right and left width of the rear side edge, and it is near the virtual center of gravity position of the entire excavator assumed when the object such as snow or earth and sand is taken into the scooping surface, or Between the left and right side edges corresponding to either the position slightly closer to the intake edge side, it is arched or gate-shaped, and the grip placed in the center extends beyond the rear side edge of the scooping surface to the handle An excavator having a gist of a configuration in which a hanging swing rod that reaches the end is spanned and each end thereof is detachably attached to a predetermined portion of the right and left side edges.

    When the excavator of the present invention is shown in a different expression, the tip is formed with a straight intake edge, and the three sides of the flat surface following the rear are formed on the left and right side edges and the rear side edge that are appropriately warped upward. It is assumed when an excavator body is formed by a scooping surface having an appropriate size and a handle extending rearward from a substantially horizontal center of the rear side edge of the scooping surface, and an object such as snow or earth is taken into the scooping surface. Between the left and right side edges corresponding to either the virtual center of gravity position of the entire shovel or a position slightly closer to the intake edge side than that, there is an arch-shaped or gate-shaped grip located at the center. A hanging swing rod that extends beyond the rear side edge of the scooping surface to reach the handle is spanned, and each end thereof is detachably attached to a predetermined portion of the left and right side edges. Suitable for swinging heel grip and handle near the scooping surface By holding the scooping surface that has taken in the object and lifting each other, the load applied to the left and right hands is reduced, and the object is moved to the target location by swinging toward the intake edge. It can be said that it is an excavator designed to end.

    When this shovel with this basic configuration is shown as having a more specific configuration, the left and right side edges and the rear edge where the tip is a straight intake edge and the three sides of the flat surface following it are warped upward moderately An excavator body is formed by a scooping surface of an appropriate size formed on the side edge and a handle extending rearward from the substantially horizontal center of the rear side edge of the scooping surface, and objects such as snow and earth and sand are placed on the scooping surface. Between the left and right side edges corresponding to either the position of the virtual center of gravity of the entire shovel assumed when taken in, or the position slightly closer to the taking edge side than that, it is arched or gate-shaped, A hanging rocking rod with a grip located in the center that extends beyond the rear side edge of the scooping surface to reach the handle, and each end is selectively detachable at a predetermined position on the left and right side edges. Excavator that is supposed to be attached It is possible to say.

    Similarly, a scooping surface of an appropriate size formed at the right and left side edges and the rear side edge where the front end is a straight intake edge, and the three sides of the flat surface following the back are appropriately warped upward, Whether the excavator body is formed by a handle extending rearward from approximately the center of the lateral width of the rear side edge of the scooping surface, and is the vicinity of the virtual center of gravity of the shovel as a whole assumed when an object such as snow or earth is taken into the scooping surface? Between the left and right side edges corresponding to either the position slightly closer to the intake edge than that, it is arched or gate-shaped, and the grip arranged in the center extends beyond the rear side edge of the scooping surface. A hanging swing rod that reaches the vicinity of the handle is hung over a scooping surface via a folding mechanism that can be reversibly changed to a substantially upright posture or an attached posture. Removably attached to the left and right edges It can be said that with the shovel.

(Related invention 1)
In relation to the above-described excavator of the present invention, the present invention also includes an excavator having the following configuration, which has a straight intake edge at the tip, and three sides of the flat surface following it are moderately appropriate. An excavator body is formed by a scooping surface of an appropriate size formed on the left and right side edges and the rear side edge that warps upward, and a handle that extends rearward from a substantially horizontal center of the rear side edge of the scooping surface, Between the left and right side edges corresponding to either the virtual center of gravity position of the entire excavator assumed when taking objects such as snow or earth on the scooping surface, or a position slightly closer to the intake edge side than that An oscillating or gate-shaped hanging rocker that has a grip located in the center that extends beyond the rear side edge of the scooping surface to reach the handle, and that can be detachably attached to each end. Arrived, handed over and attached to the ugly surface The grip can be temporarily fixed to the handle at the time of the posture, and at the time of the temporary fixing, it can be used as a part of the hanging swing rod or can be linked to the hanging swing rod separately. The excavator has a configuration in which the support legs are formed so as to protrude and temporarily fixed to the back side of the scooping surface.

    In other words, a scooping surface of an appropriate size formed by a straight intake edge at the front and a right and left side edge and a rear side edge, which are formed by three sides of the flat surface following the rear side being warped upward. And an imaginary center of gravity position of the entire shovel that is assumed when an object such as snow or earth and sand is taken into the scooping surface by forming a shovel main body with a handle extending rearward from the substantially horizontal center of the rear side edge of the scooping surface. Between the left and right side edges corresponding to either the vicinity or a position slightly closer to the intake edge side than that, it is arched or gate-shaped, and the rear side edge of the scooping face is located in the center. Suspended and swinging rods that extend beyond the handle to the handle are detachably attached to each end of the handle, and the grip is temporarily attached to the handle when attached to the scooping surface. It is possible to stop, and at the time of temporary fixing, The supporting leg, which is used as a part of the heel or separated and can be interlocked with the suspended swinging heel, protrudes to the back side of the scooping surface and is temporarily fixed. It can be said that the excavator is grounded with the intake edge so that the entire excavator can be independent.

    If the excavator included in this related invention is shown as a more specific one, the left and right side edges and the rear side where the tip is a straight intake edge and the three sides of the flat surface following it are warped upward appropriately. An excavator body is formed by a scooping surface having an appropriate size formed on the edge and a handle extending rearward from the substantially horizontal center of the rear side edge of the scooping surface, and an object such as snow or earth is taken in the scooping surface. Between the left and right side edges corresponding to either the virtual center of gravity position of the entire shovel assumed at that time or the position slightly closer to the intake edge side than that, it is arched or gate-shaped, A hanging rocking rod with a grip located in the center that extends beyond the rear side edge of the scooping surface to reach the handle, detachably attaches and hangs each end, and Bend to the back side of the scooping surface for a predetermined length In addition to being formed into a substantially L-shaped side shape, the grip can be temporarily fixed to the handle when attached to the scooping surface, and at the same time, It can be said that the excavator is formed such that the support leg portion composed of the bent and extended portions at each end protrudes and is temporarily fixed to the back side of the scooping surface.

    Similarly, a scooping surface of an appropriate size formed on the right and left side edges and the rear side edge where the front end is a straight intake edge, and the three sides of the flat surface following the back are appropriately warped upward, and the scooping The excavator body is formed by a handle extending rearward from approximately the center of the left and right width of the rear side edge of the surface, or near the virtual center of gravity position of the entire shovel assumed when the object such as snow or earth and sand is taken into the scooping surface, or Between the left and right side edges corresponding to one of the positions slightly closer to the intake edge than that, it is arched or gate-shaped, and the grip placed in the center extends beyond the rear side edge of the scooping surface. A hanging swing rod that reaches to the vicinity is attached and detachable at each end so that the grip can be temporarily fixed to the handle when attached to the scooping surface. At the same time, at the time of temporary fixing, the hanging rocker Support legs that are detachably attached to the left and right side edges of the scooping surface together with the ends, and projecting to the rear of each scooping surface, project to the back side of the scooping surface, and are generally L-shaped sideways with respect to the suspended swinging rod An excavator formed so as to be temporarily fixed to is also included.

    In addition, a scooping surface of an appropriate size formed on the right and left side edges and the rear side edge where the front end is a straight intake edge and the three sides of the flat surface following the back are appropriately warped upward, and the scooping surface The excavator body is formed by a handle extending rearward from approximately the center of the right and left width of the rear side edge, and it is near the virtual center of gravity position of the entire excavator assumed when the object such as snow or earth and sand is taken into the scooping surface, or Between the left and right side edges corresponding to one of the positions slightly closer to the intake edge side, it is arched or gate-shaped, and the grip placed in the center extends beyond the rear side edge of the scooping surface and around the pattern The suspension rocking rods which are formed so as to reach the ends, both of which are bent toward the front and bent sideways, and which have a substantially side-shaped rollover L-shape, are detachably attached to and hanged from the respective ends. Temporarily fix the grip to the handle when attached to the scooping surface There is also an excavator that is formed so that the supporting leg portion formed around the bent portion of the suspended swing swinging rod protrudes and is temporarily fixed to the back side of the scooping surface during the temporary fixing. Is included.

(Related invention 2)
In relation to the above-described shovel, the present invention also includes a swing handle used for the shovel, and its configuration is basically as follows.
In other words, it is an arch-shaped or gate-shaped, and the tip is linearly inserted at both ends of a suspended swinging heel so that the grip placed in the center extends beyond the rear side edge of the scooping surface to reach the handle. The right and left side edges and the rear side edges formed on the right and left side edges and the rear side edges, which are moderately warped upward at the three sides of the flat surface following the edge, and the center of the right and left width of the rear side edge of the scooping face A swing structure that can be attached to the right and left side edges of the excavator body that extends from the rear to the right side of the excavator and that can be mounted in a swingable manner toward the scooping edge. It is a swing handle used for the excavator described in any one of the above, which is incorporated.

    This is shown in a more specific configuration: an oscillating or gate-shaped hanging rocker that has a rotating grip that is placed in the center and extends beyond the rear side edge of the scooping surface to reach the handle. The right and left side edges and the rear side edges formed on the right and left side edges and the three sides of the flat surface following the rear side are appropriately warped upward at both ends, There is an attachment / detachment mechanism that can be attached to the right and left side edges of the excavator body that consists of a handle that extends rearward from the center of the rear side edge of the scooping surface, and is hung around each of the left and right attachment / detachment mechanisms. A folding mechanism having an elastic self-supporting structure that can be held in a substantially upright position on the scooping surface, and a swinging mechanism that can be swingably suspended toward the scooping edge. The structure that incorporates the dynamic structure That, the swing handle to be able to use the excavator underlying the inventions.

    According to the shovel of the present invention, whether the swing handle is near the virtual center of gravity position of the entire shovel assumed when the object such as snow or earth is taken in on the scooping surface, or slightly closer to the intake edge side than that. After taking snow into the scooping surface, hold the swing handle and the middle part of the handle with the right and left hands and lift it up. The swing handle itself can be lifted with the lightest weight without causing the above action, the swing handle itself is relatively lightweight, the weight of the entire excavator can be reduced, and the swing handle near the scooping surface This is a structure that lifts the grip so that it is gripped and held in the middle of the handle. As a result, it is possible to ensure high operability, greatly improve the efficiency of snow-scraping work, which was burdensome for users, and by adopting the same structure for excavators for civil engineering work, etc. In addition, it is possible to obtain an excellent feature that the excavation and transport work of earth and sand can be remarkably improved.

    In addition, with the structure in which support legs are added and formed at the right and left positions of the hanging rocking rod, if it is before, when performing other work in the middle of snow removal work, resting, or storing When you release your hand from the excavator, for example, you can leave the excavator on the ground or on the snow, leave it, or stab it on the snow surface or stand on something. The left and right support legs, which swing out to the rear, are separated by a convenient front-rear distance from the scooping-up edge, by temporarily fixing the pallet to the shovel scooping surface. The excavator body can be grounded on the ground to be able to stably stand on its own, and the excavator will be buried in the snow, expending wasted time, and mud etc. will adhere to the handle and gripping part. And dirty Cormorants, or leaning on it possible shall not cause inconvenience fall down by way, it can also be conveniently self on the ground or concrete, storage, the advantage of useful even on storing obtained.

    Therefore, in the case of an excavator represented by a snow shovel that has been generally marketed so far, it is necessary to lift a weight that is far greater than the amount of snow actually lifted by the principle of lion, In the action to crawl and throw it out toward the target location, it is necessary to repeat the work of flexing and stretching the waist greatly, and it has resulted in excessive effort on the user, and trying to eliminate such inconvenience If you add more and gripping parts, the weight of the snow shovel itself will increase, increasing the work burden on the user and degrading the work efficiency of snow scraping, etc. In addition to being able to solve all at once, leave your hands around during work, or leave it around when you move to work that does not require an excavator. Inconveniences such as disturbing the work or inadvertently scratching something that was leaning against something and being inadvertently scratched are completely eliminated, and storage in off-season is also possible In addition to being useful, it can be offered not only as a new excavator with these configurations, but also as an accessory of an existing excavator and can be used detachably as needed, which is extremely convenient. It will be rich in nature.

    In addition, according to the swing handle related to the shovel of the present invention, since it has a detachable mechanism that can be attached to and detached from the excavator body and a folding mechanism is provided, first, the existing shovel is utilized as it is. Thus, the excavator having the basic configuration of the present invention can be transformed at any time, and it can be expected that the excavator already owned as a necessity in many households can be used more conveniently without wasting it. In addition, when this swing handle is combined with the excavator body, the attachment position can be changed and adjusted according to various conditions such as the user's physique and physical strength, and the weight of objects such as snow and earth and sand. Therefore, it can be used by anyone regardless of age or gender under optimal conditions. If the hanging swing rod is folded along the scooping surface so that it can be temporarily attached to the handle, it is handled as something that is not different from a normal excavator, and it has almost the same workability. The operability in the work of throwing out the target object by lifting or swinging by the user is greatly improved, such as digging snow and earth and sand, raising the object, and throwing it toward the target location This makes it possible to perform a series of operations smoothly and accurately, and exhibits an excellent effect that the burden on the operator can be greatly reduced.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The hanging rocker is compatible with either the position of the virtual center of gravity of the entire excavator assumed when the object such as snow or earth is taken into the scooping surface, or a position slightly closer to the intake edge. The left and right edges of the scooping surface can be held in a suspended manner in a swingable manner in the direction of the scooping surface, and can be held by either the left or right hand and scooped by the left or right hand Hold the scooping surface that holds the object in the vicinity of the surface, hold the scooping surface that has taken in the object, suspend it with less burden on the left and right hands, swing it in the direction of the intake edge, and throw the object to the target location It must be provided with a rocking structure that can be folded, and consists of an arch-type or gate-type ridge made of steel cable or wire, to the left and right ends of the ridge, and to the left and right edges of the scooping surface The connecting part with the connecting bracket forms a swinging structure. It can be assumed that the composed.

    The grip reduces the burden on the hand when gripping the hanging swing rod and reduces the burden on the operator such as hand pain when performing snow removal work or earth transport work. For right-handed workers, use a swinging oscillating rod when the intake edge is in front, or for left-handed workers, suspending oscillating rod when the intake edge is in front Although it is possible to provide it at a position close to the right side, it is desirable that it should be provided near the center of the left and right of the suspended swing rod so that anyone can use it easily. It is possible to provide a rotary grip that does not move in the (center) direction but is provided so as to be freely rotatable about the axis of the suspended swinging rod.

    The folding mechanism has a function that allows the suspended swinging rod to be placed on its side so that it lies along the shovel scooping surface, and can be changed from a sideways posture to a substantially upright posture with respect to the scooping surface. It can be folded around the left and right ends of the swing rod by a shaft attachment structure or a connecting structure such as a chain or string, or it can be an elastically deformable steel rope, wire or synthetic resin hanging swing rod itself Can be bent into a curved shape, and can be formed into a structure having a swinging structure that allows the excavator body to be swung in the edge direction. Elastic self-supporting structure that is provided at the connecting part between the left and right ends of the moving rod and the connecting bracket to the left and right edges of the scooping surface, and that constantly urges the suspended swinging rod to a generally upright posture with respect to the scooping surface Shall be incorporated The folding mechanism is equipped with a hooking mechanism that temporarily fixes the hanging swing rod when it is attached to the scooping surface. Desirably, it is provided at any suitable place in the vicinity of the rear edge.

    When the elastic self-supporting structure has a folding mechanism, when the elastic self-supporting structure is unfolded so that the elastic self-supporting structure functions, the suspended swing rod is set in a substantially upright posture with respect to the scooping surface. It serves to support elastically so that it can be maintained. More specifically, a pipe made of synthetic resin that can be elastically deformed is mounted near both ends of the hanging swing rod and folded when the pipe is folded. When moving the suspension rocker along the hanging rocking rod, remove it from the pivot attachment points (folding mechanism) on both ends, and make the hanging rocking rod upright, move the pipes to the left and right pivoting points. In addition, it is structured so as to be elastically supported by being attached to each of the left and right end shaft attachment locations, or urging the hanging swing rod to rotate in the upright direction at each of the left and right end attachment locations. A torsion coil spring is installed, and the hanging swing rod is in an upright position. It like is possible to provided an upright position regulating part that prevents from being overturned in intake edge than necessary structure to regulate the.

    The swing structure grips the grip of the suspended swing rod, holds the handle near the scooping surface, makes the entire excavator suspended below the grip swing freely toward the scooping edge, It has a function that allows the scooping surface to be swung over a range larger than the horizontal movement amount of the hand holding the swinging saddle grip, and has a suspension strength according to objects such as snow or earth and sand. A structure that can swing at least from a posture in which the suspended swing rod is upright with respect to the scooping surface to the extent that the suspended swing rod grip reaches the handle near the shovel scoop surface. It should be the one that also functions as a folding mechanism, or one that has an elastic self-supporting structure.

    When the excavator body is set up with the tip of the intake edge in contact with the ground, the support leg protrudes from the left and right sides of the scooping surface, and can be stably supported by extending and grounding. This function serves to support the excavator body, and when using the excavator, it is generally folded along the scooping surface, and only when the excavator body is self-supporting, the rear side of the scooping surface The shovel main body should be able to be supported so as not to fall over, for example, from the respective end portions of the hanging swing rods to have a substantially L-shaped side shape at a predetermined angle. And can be temporarily fixed in both a substantially L-shaped posture and a posture that is folded so as to follow the left and right edges of the suspended swinging ridge or scooping surface. A stop mechanism is attached. Outside, the left and right ends of the hanging swing rod are bent into a side-shaped, roughly rollover L-shape toward the front, respectively, and the hanging swing rod is bent at the right and left positions. The part vicinity may be a supporting leg.

    The temporary fixing mechanism has left and right support legs that are foldable at each end of the hanging swing rod so that they protrude toward the left and right rear of the shovel scooping surface, and are grounded together with the leading edge of the shovel. The overall function is to be able to be temporarily fixed in both the posture that enables self-supporting and the posture that is folded along the suspended swinging ridge or scooping surface, and is attached. The base end side of the support leg should be able to be temporarily fixed in a desired posture in the vicinity of each end of the swinging rod, and each end of the hanging swinging rod must also be on the left and right sides Internal gears whose axial centers are oriented in the right and left horizontal direction are integrated at midpoints, and gears that can be meshed with the corresponding internal gears are provided at predetermined angles at the respective base end portions of the corresponding left and right support legs, Assuming that a male screw with a hook for connection is concentrically integrated at the center of the gear, As an arbitrary angle and posture in which the supporting leg portion is desired with respect to the heel, the internal gear and the gear are fitted, and the wing nut with the heel is screwed into each of the male threads with the heel through the internal gear, The suspension swing rod and the left and right support legs can be temporarily fixed to their angular postures and can be connected to each other, and can be connected to the support legs near the base end side of the support legs. A hanging branch portion standing upright with a predetermined opening angle and a hanging branch portion substantially parallel to the support leg portion are provided, and any of the hanging pipes is attached to the connecting pipe attached to the hanging swing rod. By mounting the stop branch so as to be inserted, it is temporarily fixed in a posture that is substantially L-shaped on the side with respect to the hanging swing rod, or in a posture substantially parallel to the hanging swing rod. It is possible to temporarily fix it.

    The grounding plate expands the grounding area of the grounding part of each support leg, prevents sinking on the snow, enables stable grounding, has a shovel gripping part, and has a scooping bottom. When carrying it so that it touches and slides on the snow, the grounding part of the left and right support legs will function to enable smooth sliding on the snow, and the excavator will stand on the snow. A sufficient contact area must be secured, and an upward curved surface shape is formed in the direction from the tip of the shovel receiving edge toward the handle, and when the drag is moved with the handle, Should play a role. In the following, the structure of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.

    The example shown in the side view of the shovel in FIG. 1, the perspective view of the shovel in FIG. 2, and the front view of the detaching mechanism provided in the hanging swing rod in FIG. 3, forms a straight intake edge 21 at the tip. Then, the three sides of the flat surface following the back are appropriately warped upward to provide a scooping surface 2 of an appropriate size formed on the left and right side edges 22, 22 and the rear side edge 23, and the scooping surface 2 rear side edge 23 The excavator body 11 is provided with a handle 3 that extends rearward at the center of the left and right widths, and the vicinity of the virtual center of gravity G of the entire shovel assumed when the snow S is taken into the scooping surface 2 Alternatively, the grip 6 to be arranged in the center of the arch shape is located between the left and right side edges 22 and 22 corresponding to any of the positions slightly closer to the intake edge 21 than the scooping face 2 rear side edge. A hanging swing rod 5 that extends over 23 to reach the handle 3 Shows one example representative of the excavator 1 of the present invention comprising a basic structure that each of its ends, which are mounted detachably at a predetermined position of the left and right side edges 22, 22.

    The shovel 1 has a polycarbonate scooping surface 2 and a wooden handle 3 provided at the rear of the scooping surface 2, and the tip of the scooping surface 2 is formed substantially linearly with respect to the handle. An intake edge 21 is formed, and a reinforcing metal plate is provided on the intake edge 21 as necessary, for example, when the scooping surface 2 is made of a material with relatively low hardness such as ABS or aluminum. It is desirable to form a plurality of concavo-convex shapes for reinforcement and a plurality of through holes for weight reduction on the flat surface continuous to the rear of the intake edge 21, and the right and left side edges 22 thereof. , 22 and the rear edge 23 are warped upward and the upper and lower edges of the left and right rear edges 22, 22, 23 are bent downward as shown in FIG. It is supposed to form a reinforcing frame shape.

The handle 3 is set to a length dimension that allows a user who puts his / her foot on either the left or right side of the scooping surface 2 to hold the end on the opposite side of the scooping surface 2 and pierce the snow. The end portion on the side opposite to the scooping surface 2 is equipped with a synthetic resin gripping portion 31, but the weighting portion 31 is not provided for the purpose of weight reduction. You can also.

Furthermore, the left and right end sides of the grip 6 and the pivoting portions of the left and right ends of the hanging swing rod 5 Are connected and reinforced by reinforcing wires 59 and 59.

(Operation of Example)
The excavator 1 and the swing handle 4 therefor having the above-described configuration are provided at the left and right ends of the hanging swing rod 5 of the swing handle 4 as shown in FIGS. Each of the clip portions 91 and 91 of the attachment / detachment mechanism 9 corresponds to a position slightly closer to the intake edge 21 side from the vicinity of the virtual center of gravity position G of the entire shovel 1 assumed when the snow S is taken into the scooping surface 2. Assuming that the left and right edges 22 and 22 are clamped via mounting reinforcing frames 93 and 93 so as to be arched between the left and right edges 22 and 22 and are detachably mounted, the suspended roll over the scooping surface 2 By putting the rotary grip 6 of the lower swing rod 5 into a state where the rotary grip 6 is fitted to the hooking mechanism 84 provided on the handle 3, it can be used in the same manner as a general snow shovel, and the grip at the end of the handle 3 can be gripped. Husband with holding part 31 and the same pattern 3 mid-point The snow is removed by scribbling the snow with the left and right hands to squeeze the snow cover S, or by placing a foot on either the left or right side of the rear edge 23 of the scooping surface 2 and piercing the scooping surface 2 into the snow. It is possible.
Then, in a state where the snow S is taken in on the scooping surface 2, the rotating grip 6 of the suspended swinging cage 5 is removed from the hooking mechanism 84, and the rotating grip 6 is gripped by one of the left and right hands. It is possible to lift the scooping surface 2 with both the left and right hands by grasping a suitable place within the range indicated by the optimum holding range display unit 32 of the handle 3 with either one of the two.

    As shown in the side view of the shovel showing the handling weight as a vector in FIG. 6, in the case of the conventional shovel shown in FIG. 6A, the distance d is about 60 cm away from the virtual center of gravity position G. In the middle of the handle 3, the gripping portion 31 that is further away by a distance D of about 60 cm (about 120 cm from the virtual center of gravity position G) is gripped by the left and right hands, and the weight W acting on the virtual center of gravity position G is raised. Is 5 kg, the downward force F of the gripping part 31 is 5 kg, and the upward force L of the middle part of the handle 3 is 10 kg. It will reach even to.

    According to the conventional improved excavator shown in (b) of the figure, it is suspended as shown by a chain line at an appropriate position on the scooping surface 2 corresponding to a position of a distance d of about 5 cm from the virtual center of gravity position G to the handle 3 side. When a hanging rod is provided, the hanging rod is gripped with one hand, and a handle 3 with a distance D of about 50 cm is held from the hanging rod and lifted by holding an appropriate position, the weight W acting on the virtual center of gravity position G is 5 kg. In this case, the force L applied to the hand for lifting the hanging rod is 5.5 kg, the downward force F applied to the hand in the middle of the handle 3 is 0.5 kg, and the total weight to be lifted is 6 kg. Although significantly improved compared to the excavator, it still required 6 kg of force to lift the 5 kg weight.

    On the other hand, according to the shovel 1 having the structure, as shown in FIG. 5C, the weight W acting on the virtual center of gravity position G lifts 5 kg, but the distance d from the virtual center of gravity position G to the intake edge 21 side. A force of 4 kg indicated by L1 is applied to the hand that lifts the hanging swing rod 5 attached at a position of about 10 cm, and the optimum holding range display section 32 of the handle 3 that is a distance D of about 40 cm away from the virtual center of gravity position G is displayed. A force of 1 kg indicated by L2 is applied to the gripped hand, and the total weight that must be lifted by both hands can be suppressed to 5 kg, which is the same as the weight W acting on the virtual center-of-gravity position G.

    The excavator 1 lifted so as to be held by the left and right hands in this manner is suspended when the excavator body 11 is swung in the direction of the intake edge 21 indicated by the white arrow in FIG. In the swing range of the swing rod 5, it becomes possible to secure a much larger swing width than a conventional excavator without the suspended swing rod 5, and the snow S can be accurately discharged toward a farther target location. It will be possible.

    The suspension rocking rod 5 is always elastic in the vicinity of the central portion where the rotating grip 6 is mounted by the torsion coil spring 82 of the elastic self-supporting structure 81 provided at the left and right ends shown in FIG. In addition, the regulating bolt 83 restricts the scooping surface 2 to an upright posture with respect to the scooping surface 2, and the swing operation is freely performed between the regulating bolt 83 and the handle 3.

    As shown in FIGS. 1 and 2, the shovel 1 that has finished snowplowing folds the hanging swing rods 5 by folding the folding mechanisms 8 and 8 formed at both ends thereof, and rolls over the handle 3 side. The rotating grip 6 can be stored in a state of being fitted to the hooking mechanism 84, and the clip portions 91, 91 of the attaching / detaching mechanisms 9, 9 at the left and right ends of the hanging swing barb 5 are arranged on the scooping surface 2. It is also possible to remove the swing handle 4 from the left and right edges 22 and 22 and store and manage the swing handle 4 separately from the excavator body 11. When the swing handle 4 is mounted on the excavator body 11 again, the scooping surface 2 insertion edge 21 from the vicinity of the virtual center of gravity position G each time according to various conditions such as the user's physique and physical strength or the weight of snow. It is possible to attach and use it at a position where it is easy to work.

    Further, according to the folding mechanism 8 also serving as the elastic self-supporting structure 81 in FIG. 5, the left and right upright pipes 87 are moved upward as indicated by the white arrows and detached from the connection fitting 86, thereby 5 is foldable with respect to the connecting fitting 86, and the left and right upright pipes 87 are moved downward and fitted into the connecting fitting 86, the upper edge of the temporarily fixed upright pipe 87 is suspended. The left and right ends of the swinging rod 5 are supported upright and elastically with respect to the scooping surface 2, and the user swings and holds the suspended swinging rod 5 to take in the shovel 1 and swing toward the edge 21. As a result, the upright pipe 87 is elastically deformed in accordance with the swinging of the hanging swinging rod 5, thereby enabling a smooth swinging operation.

    The shovel 1 shown in FIG. 7 can reduce the work load of snow removal similarly to the above-mentioned one, and, as shown in FIG. When the grip 6 is hooked on the hooking mechanism 84 by rotating it so as to follow the hook 2, the left and right support legs 51, 51 are swung out behind the scooping surface 2, and the intake edge 21 is grounded. At the same time, by grounding the grounding saddle plates 52, 52 at the tips of the support legs 51, 51, the shovel body 11 can be made independent as shown in FIG. As shown by the white arrow in FIG. 9, the grip 6 is detached and the suspended swinging rod 5 is made upright with respect to the scooping surface 2 so that the intake edge 21 side is grounded. Direction of travel when moving while gripping and dragging the grip portion 31 Opposite is ground sled plate 52, 52 of each support leg 51 smoothly becomes possible sliding movement.

    10 to 12 has a posture in which the supporting leg portions 51 and 51 are deployed with respect to the hanging rocking rod 5 as shown in FIG. 54 is arranged so as to follow the suspended swinging rod 5, and the connecting pipes 53, 53 are slid and fitted as shown by the white arrows in the figure, so that each support leg portion 51 is fitted. , 51 can be temporarily fixed to a posture deployed at a predetermined angle, and the support legs 51, 53 are slid by moving the connection pipes 53, 53 away from the deployment posture connection branches 54, 54. 51 is released in a swingable manner. Further, as shown in FIG. 12, the support leg portions 51 and 51 are folded so as to follow the hanging swing rod 5, and the connecting pipes 53 and 53 are slid and moved as indicated by white arrows in FIG. Then, by temporarily fixing the folding posture connecting branches 55 and 55, it is possible to temporarily fix the support leg portions 51 and 51 to the hanging swing rod 5 in the folded state.

    The support legs 51 and 51 shown in FIG. 13 and FIG. 14 are hooked to the corresponding hooks 57 and 57 when they are swung to a desired angle posture with respect to the hanging rocker 5. It is possible to temporarily fix the ring 58, 58,... To a desired angle posture by hooking the ring 58, 58,. By appropriately changing the posture angle of each of the support legs 51, 51, the shovel body 1 as shown in FIG. 8 can be self-supported, and smooth drag transfer as shown in FIG. 9 can be performed.

    15 and 16 is also rotated when the grip 6 is hooked on the hooking mechanism 84 provided at an appropriate position of the handle 3 so as to follow the scooping surface 2. 16, the scooping surface 2 intake edge 21 and the support leg portions 51, 51 swinging out to the left and right rear are grounded to allow the excavator body 11 to stand on its own, and as it is The left and right support legs 51, 51 formed by bending right and left midpoints of the hanging swing rod 5 smoothly on the snow or on the ground even when the gripping portion 31 of the excavator 1 is gripped and dragged. Further, the hanging swing rod 5 that is bent at right and left midpoints connects the left and right sides of the grip 6 and the corresponding left and right ends with reinforcing wires 59 and 59. Snow on the ugly side 2 Even when responsible for the load reinforcement wire 59, and which prevents the deformation of the support legs 51 and 51.

(Effect of Example)
The excavator 1 and the swing handle 4 for the embodiment having the above-described configuration are provided with a hanging swing rod 5 and a rotating grip using a rope in addition to the features described in the section of the effect of the present invention. 6 can secure sufficient strength while being lightweight, can also ensure good operability, and the attachment / detachment mechanism 9, 9 is provided with the clip portions 91, 91, and the detachment work Can be performed in a short period of time, and the mounting position can be adjusted and changed quickly, so that it is easy to use, and the left and right sides are a combination of the torsion coil spring 82 and the regulating bolt 83. Since the suspended swinging rod 5 is elastically upright with respect to the scooping surface 2 by the elastic self-supporting structures 81, 81, the rotary grip 6 of the swing handle 4 can be held without bending the waist. In addition, the optimum holding range display unit 32 can be used as a guide for accurately grasping the right place of the long handle 3, and it can be lifted with a good balance to eliminate the need for re-holding and more efficient. This will bring about the effect of enabling a snow-plowing work.

    In addition, the additional support legs on the left and right sides of the hanging swing rod allow the excavator body to be self-supporting using the support legs when the shovel is released or stored. Until then, if you let go of the excavator during snow removal work, if you pierce the excavator's scooping surface in the snow, or if the snow is frozen, you have to leave the excavator as it is. While we were tired of snow removal work, we had to spend the effort to push up the shovel and pick up the shovel that was rolling over, but it was easy to stand on frozen snow and on the ground. It can be made much easier to use than conventional shovels.

    In addition, a grounding saddle is provided at each support leg grounding location, so that when the excavator is made to stand on its own, a sufficient grounding area is ensured, even on a soft ground surface or on snow. Even when the excavator handle is dragged and moved by dragging, etc., the grounding plate surface in which each grounding plate is warped in the traveling direction can be used. Since it forms, the advantage that it can convey smoothly without burdening a user can be acquired.

(Conclusion)
As described above, the excavator of the present invention and the swing handle for the excavator are capable of achieving the intended purpose evenly by the novel configuration, and are easy to manufacture and can be provided at low cost. It is also possible to install and use the swing handle in an optimal state even for an excavator that has been used for a long time, as compared to conventional excavators and conventional improved excavators, Because it is far more economical and the work efficiency itself can be greatly improved, the work load on the person who uses it is greatly reduced, and the work time by the shovel such as snow scraping work and civil engineering work is remarkably shortened. From the various industries involved in the manufacture and sale of snow removal tools and tools that are required to improve work efficiency, Even though it becomes possible to be appreciated from the general consumer to use it, use over a wide range, is expected to be those that continue to spread.
