A hammer that doesn't clap its hands

Abstract

To provide a hammer that prevents accidental hand injuries when striking objects such as nails. [Solution] The hammer 1, which prevents the user from hitting their hand, has a striking part 3 at the lower end of the handle 2 and a stopper part 4 and a nail puller part 41 at the upper end. The side of the striking part 3 opposite to the side connected to the handle 2 is the striking surface 32, and the striking surface 32 is about the same size as or larger than the hand gripping the handle 2. By moving the striking surface 32 in a straight line in the extending direction to strike an object such as a nail, it is possible to prevent accidentally hitting one's hand.

Description

Technical Field

[0001] The present invention relates to a hammer that prevents accidentally striking a hand holding an object when striking an object such as a nail or a peg. Background Art

[0002] Figure 5 is a diagram showing the operation of striking an object with a conventional hammer. When driving an object 201 such as a nail or a peg with a conventional hammer 5, it is necessary to strike the object while holding the object 201 with a hand 202. The conventional hammer 5 is provided with a striking portion 7 at the tip of a long handle 6, and a surface horizontal to the extending direction of the handle serves as a striking surface 8. With this shape, a user strikes the object 201 along a circular motion trajectory using centrifugal force with the point where the handle 6 is gripped by a hand 200 as a fulcrum. In this case, since the distance between the hand 200 gripping the handle 6 and the object 201 is long, it is difficult to bring the striking surface 8 into contact with the object 201, and cases where the user's hand 202 is struck and injured frequently occur.

[0003] Patent Document 1 Japanese Utility Model Registration No. 3192123 Bulletin Summary of the Invention Problems to be Solved by the Invention

[0004] When driving a nail or the like, the hammer described in Patent Document 1 allows a user to strike while preventing hand injuries by inserting the nail or the like and a striking block into a circular hole of a tubular member stored in the hammer and striking the striking block with a hammer head. In this case, in addition to the effort of storing and taking out the tubular member and the striking block, it also takes effort to insert the nail or the like and the hammer into the tubular member, so there is concern about a decrease in productivity.

[0005] Accordingly, an object of the present invention is to provide a hammer that can ensure safety without impairing productivity when striking an object such as a nail. [Means for solving the problem]

[0006] To achieve the above objective, the present invention provides a hammer having a striking surface at the lower part of the handle that is approximately the same width as the hand gripping the handle, and the striking surface of the striking surface being perpendicular to the extension direction of the handle, wherein the striking surface is moved linearly in the extension direction of the handle to strike an object.

[0007] A stopper is provided at the top of the handle, and the shape of the stopper is designed to resemble a nail puller. [Effects of the Invention]

[0008] With this configuration, the hand gripping the handle, the striking surface, and the target object are always in the same line, making it easier to aim and significantly reducing the risk of accidentally hitting one's hand. Furthermore, having a striking surface roughly the same size as the hand gripping the handle prevents contact between the object and the hand gripping the handle, even if the striking surface doesn't directly hit the object. Moreover, since no tools other than the hammer are used, the work can be performed efficiently. Additionally, a stopper at the top of the handle prevents the hammer from slipping from the hand, and because the stopper's shape resembles a nail puller, it also has nail-pulling capabilities.

[0009] [Figure 1] Figure 1 is a perspective view of an embodiment of a hammer that does not strike the hands. [Figure 2] Figure 2 is a side view of a hammer that does not strike the hands. [Figure 3] Figure 3 is a front view of a hammer that does not strike the hands. [Figure 4] Figure 4 is a plan view of a hammer that does not strike the hands. [Figure 5] Figure 5 shows the action of striking an object with a conventional hammer. [Figure 6] Figure 6 shows the action of striking an object with a hammer without striking the hand. [Modes for carrying out the invention]

[0010] Figure 1 is a perspective view of the hand-striking hammer 1 of this embodiment. Figure 2 is a side view of the hand-striking hammer 1. Figure 3 is a front view of the hand-striking hammer 1. Figure 4 is a top view of the hand-striking hammer.

[0011] The hammer 1, which does not strike the hands, is equipped with a handle 2, a striking part 3, and a stopper part 4.

[0012] Handle 2 is a long, slender component in one direction, intended for gripping with the worker's hand 100. It can be made of various materials such as metal, wood, or resin.

[0013] The striking portion 3 is provided at the lower end of the handle 2. The handle 2 and the striking portion 3 may be manufactured as a single unit by casting, connected by welding, or connected by screws with nuts or the like. The striking portion 3 is cylindrical in shape and extends in the direction of extension of the handle 2. Of the striking portion 3, the side connected to the handle 2 is the connecting surface 31, and the opposite side is the striking surface 32.

[0014] The stopper portion 4 is provided at the upper end of the handle 2. The shape of the stopper portion 4 is flexible, but it should have a groove shape similar to that of the nail puller 41. The handle 2 and the stopper part 4 may be manufactured as a single unit by casting, connected by welding, or connected by screws with nuts or the like.

[0015] The hand-free hammer 1, configured as described above, makes it easier to hit an object 201 such as a nail precisely, compared to the operation of the conventional hammer 5 explained in Figure 5, and reduces the risk of accidentally hitting the hand 202 that is holding the object 201. The method of using the hand-free hammer 1 of this embodiment will be described below.

[0016] Figure 6 is a diagram illustrating the action of striking an object 101 with a hammer 1 that does not strike the hand.

[0017] When striking an object 101 with the non-hand-striking hammer 1, the non-hand-striking hammer 1 is caused to perform linear motion along the extension direction, and the object 101 is struck with the striking surface 32. At this time, since the hand 100 gripping the handle, the striking surface 32, and the object 101 are always on the same straight line, it is easy to aim, and the risk of accidentally striking the hand 102 gripping the object 101 is greatly reduced. In addition, by providing the striking surface 32 having a size approximately equal to that of the hand 102 gripping the handle 2, contact between the object 101 and the hand gripping the handle 2 can be prevented even when the striking surface 32 cannot be applied to the object 101.

[0018] Note that the handle 2, striking portion 3, and stopper portion 4 are not limited to the above-described embodiments. For example, in Fig. 1, the handle 2 and the striking portion 3 are columnar, but they may also be polygonal prismatic or columnar solids with non-uniform bottom surfaces. [Description of Symbols]
