Abstract

(57) [Summary] [Purpose] To obtain a hand runner that has a long life, can be adjusted in weight, and does not lose stones even when it is pierced from above a work etc. (for example, four stones in a grave). [Structure] A main body 1 made of a metal bottomed cylindrical body, a rubber shock absorbing member 2 attached to the bottom thereof, a lid 3 detachably attached to an upper opening of the main body, and a main body A hand rammer consisting of multiple attached handles 4.
The bottom surface of the shock-absorbing member 2 has a shape in which the central portion projects from the peripheral portion so that the soil can be compacted even when the hand rammer is slanted. The lid 3 is removed, and gravel or the like is put inside the cylindrical body of the main body to adjust the weight. When the hand rammer is struck in that state, gravel or the like that falls later acts to press the momentum of the main body by the shock absorbing member from above, so that the effect of compacting the soil is increased.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used for tamping the foundation soil or split stones on which work pieces (such as gravestones in the grave or stepping stones in the garden) are set, or when the work pieces are struck from above and leveled. Regarding hand rammer.

[0002]

[Prior art]

 A conventional hand rammer is a wooden tool (commonly known as an octopus) that has 2 to 4 handles attached around a cylindrical hard tree. It can be easily used anywhere, and even if it is struck by a stone, it will be impacted by the stone. Since it does not chip, for example, it is used for compacting the soil in the place where the gravestones, quarts stones, stone lanterns, etc. are to be set up, or after installing, poke it from above and level it Often used.

However, a wooden hand rammer has a life of only 2 to 3 years because the columnar shape, especially the tip portion of the wooden hand rammer becomes thin and rots during use, and the handle falls off. The weight of a wooden hand rammer cannot be changed after it is manufactured, so depending on the person, be patient with the weight that does not fit, or prepare multiple weights that match the physical strength of the user. And so on.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above conventional problems, and an object thereof is to obtain a hand rammer having a long service life, capable of weight adjustment, and having a high tamping function and a leveling function for a workpiece or the like. .

[0005]

[Means for Solving the Problems]

 The present invention includes a main body made of a metal bottomed tubular body, a shock absorbing member attached to the bottom of the main body, a lid detachably attached to an upper opening of the main body, and the main body. The present invention relates to a hand rammer characterized by comprising a plurality of grips attached and extending upward. Preferably, the shock-absorbing member is made of rubber, and the bottom surface of the shock-absorbing member has a central portion protruding from the peripheral portion. It is characterized by

[0006]

[Action]

 The hand rammer according to the present invention has a main body made of metal, but has a shock absorbing member made of rubber or the like attached to the bottom, so that the stone will not be chipped even if it is pierced from the top of the stone. It can be used in the same way as octopus. Also, the weight can be adjusted by opening the lid and putting sand, stones, gravel, etc. inside the tubular body of the main body. If you pour the soil with a proper amount of gravel inside, the body will pierce the soil and then the gravel will fall vigorously inside the tubular body with a force greater than the weight of the gravel inside. Has a high function of compacting the soil because the gravel acts on the soil and the fallen gravel acts to press the body of the body from the impact cushioning member from above. The same action works when poking from a stone or other workpiece, and the leveling function also increases. If the bottom surface of the shock-absorbing member has a shape such that the center of the shock-absorbing member extends beyond the periphery, for example, if the center of the shock-absorbing member has a flat shape and the periphery is inclined upward, the soil may be struck slightly diagonally. It can be compacted well, and it has a high compaction effect when struck straight. Similarly, when projecting horizontally from the top of a work etc., you may also project it at a slight angle.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 show a hand rammer of a type having two handles, which is made of a metal body having a bottomed cylindrical body 1, and made of neoprene rubber attached to the bottom of the body 1 with an adhesive. It comprises an impact cushioning member 2, a lid 3 detachably attached to the upper opening of the main body 1, a handle 4 attached to a side target position of the main body 1, and the like.

The bottom surface of the shock absorbing member 2 has a shape in which the central portion 2a has a planar shape, the peripheral portion 2b is inclined upward, and the central portion 2a overhangs the peripheral portion 2b as a whole. A flange portion 2c rises around the shock absorbing member 2 and covers the bottom side surface 1a of the main body 1. In addition, it is preferable that the neoprene rubber forming the shock absorbing member 2 has a hardness of NS 70 to 80. A bracket 5 is attached to the inside of the main body 1 at a position closer to the upper side, and a bolt 6 is fixed to the center of the main body 1 with a screw facing upward. The lid 3 is detachably attached to the upper opening of the main body 1 by means of bolts 6 and nuts 7. In addition, a bar 8 that connects both handles 4 is provided.

FIG. 4 shows another embodiment of the hand rammer of the present invention, which is the same as the above embodiment except that four handles 4 are attached. In the case of this embodiment, a bar 9 connecting the two handles and a bar 10 connecting the nine handles are attached.

When using the above-mentioned hand rammer, the lid 3 is opened and an appropriate amount of gravel or the like is put into the main body 1 to adjust the weight (it may not be put in if not necessary), and the lid 3 is closed again. To use. Since the bottom of the main body 1 is covered with the shock absorbing member 2 made of neoprene rubber, the stone will not be chipped even if it is struck from above the stone, and the bottom side surface 1a of the main body 1 is also covered with the shock absorbing member 2. Therefore, it is possible to prevent the side surface of the main body 1 from hitting a workpiece such as a stone and damaging the stone.

Then, when the hand rammer is used for poking, as described in the above [Action] column, the effect of the impact force of the fall of the main body 1 and the impact force of the fall of the gravel or the like put in the body 1 is effective. The soil can be compacted well, and it can be leveled by sticking it on stones. Further, since the bottom surface of the shock absorbing member 2 has a shape in which the central portion 2a has a planar shape and the peripheral portion 2b is inclined upward, and the central portion 2a overhangs the peripheral portion 2b as a whole, The soil can be compacted well even if it is pierced at an angle, and it has a high compaction effect even when pierced straight.

By attaching the bars 8 to 10 to the handle 4, it is possible to suppress the vibration of the handle when the hand rammer is pushed, which is convenient for carrying.
