Peg with groove (protrusion)

Abstract

To provide a peg capable of minimizing the risk of a driven peg coming out when fixing a ground installation such as a tent to the ground with a string or the like and capable of being easily removed with a crowbar. [Solution] The peg of this invention has a groove 4 in the core rod of the peg body, and the string can be fixed in the groove at the part of the peg closest to the ground when it is driven into the ground, so the string does not slide to the top of the peg and it is very difficult to pull out. The presence of the groove also increases the surface area of ​​the peg that comes into contact with the ground, making it even more difficult to pull out. At the same time, this groove makes it possible to always keep the fulcrum of the crowbar on the ground when using a crowbar to pull out the peg.

Description

[Technical field]

[0001] This relates to a peg used to fasten objects such as tents to the ground with rope. [Background technology]

[0002] The usual method for fixing objects such as tents to the ground is to drive a peg into the ground and tie a string to the peg to fix it to the ground. There are various shapes of pegs used for this purpose, but generally, regardless of the shape of the peg or how deeply it is driven into the ground, the string is always attached to the tip of the peg (the part above the ground). Summary of the Invention The problem the idea is trying to solve

[0003] The usual method for fixing objects such as tents to the ground is to drive a peg into the ground and tie a string to the peg to fix it to the ground. Regardless of the shape of the peg or the depth to which it is driven, the string is generally attached to the tip of the peg (the part that is driven in with a hammer, etc.). In addition, for pegs that do not have a hole for attaching the string at the tip, the string is wrapped around the stick part of the peg to fix it, but if the string is pulled too hard, it will slip and move to the top of the peg, that is, the farthest point from the ground. Regardless of which method is used, in order to make it difficult for the peg to come out of the ground, it is necessary to drive the peg firmly into the ground until the string touches the ground. However, in reality, it is often difficult to drive the peg all the way to the tip. In other words, it often happens that the peg ends up only being driven in about 1 / 2 or 2 / 3 of the way. However, if the peg is driven in only halfway, the distance between the fulcrum and the force point is far according to the principle of leverage, so the peg can easily come out. This invention is a peg that has been designed so that the string always remains on the ground (the distance between the fulcrum and the point of force of the lever is as close to zero as possible) regardless of how far the peg is driven into the ground. Also, when pulling out a peg, a crowbar is usually used, but by inserting the crowbar into the tip of the peg (hooking the crowbar onto the peg) and pulling it out using the principle of a lever, it can only be moved a short distance between the fulcrum and the point of force of the crowbar. In other words, with a normal peg, it is only effective as a crowbar the first time it is pulled out. Means to solve the problem presented by this invention

[0004] There is a groove (protrusion) in the core rod of the peg, and by driving the peg into this groove, the string can always be fixed in the desired position on the ground. In other words, the string is fixed in place by hooking it into the groove of the driven peg that touches the ground, and the distance between the fulcrum and the force point of the lever principle becomes infinitely close to zero, making it possible to fix the string in a position that makes it most difficult for the peg to come out. Also, when using a crowbar or something to pull out the peg, by changing the position (groove) into which the tip of the crowbar is inserted depending on the position from which the peg comes out, it is possible to always keep the fulcrum of the crowbar on the ground. Effects of the invention

[0005] When using pegs, the string is usually attached to the top of the peg, assuming that it will be driven all the way into the ground. However, depending on the condition of the ground, there are cases where it is not always possible to drive the peg all the way in. In other words, pegs are often used by driving them in only 1 / 2 or 2 / 3 of the way. In that case, the string is at the top of the peg, which makes the distance between the fulcrum and the force point of the lever longer, and the peg can easily come out. However, with the peg of this invention, the string is always on the ground regardless of how far the peg is driven in, so the distance between the fulcrum and the force point approaches zero, making it possible to minimize the peg coming out. At the same time, the presence of the grooves (protrusions) increases the contact area of ​​the peg in the ground, making it more difficult to come out. Furthermore, when pulling out a peg, a crowbar is usually used, and the general method of using a crowbar is to insert it into the tip of the peg and pull it out using the principle of leverage (the part of the crowbar that touches the ground is the fulcrum, and the tip of the peg is the point of application), but this method is only effective over the short distance between the fulcrum and point of application of the crowbar itself, and the distance it can be pulled out is also short. In other words, after the initial pulling action (the distance between the fulcrum and point of application of the crowbar), it can no longer function as a crowbar, but with the peg of this invention, the groove (protrusion) closest to the ground on the peg side is used, and the tip of the crowbar can be clamped into this groove, making it possible to use the crowbar so that the fulcrum of the crowbar is always above the ground regardless of how far the peg is driven into the ground. [Brief description of the drawings]

[0006] The top of the peg is the striking point for a hammer, and the middle part has several grooves (protrusions) for hooking a string (the attached diagram shows the grooves as five levels of protrusions), and the bottom part is for driving into the ground. This groove not only hooks the string, but also serves to fix the tip of a crowbar at the closest position to the ground when removing the peg with a crowbar or the like. Also, the grooves (protrusions) and the driving part at the bottom are on the same line, so even if you drive the peg into the middle grooves (protrusions), the grooves (protrusions) will not get in the way of driving the peg.

[0007] To provide a peg having several grooves (projections) for fixing the position of the string in the middle bar of the peg, which enables the string to be fixed at a position where it always comes into contact with the ground regardless of how far the peg is driven into the ground, and which is extremely resistant to coming loose as the fulcrum and the point of force of the principle of leverage are located at an extremely short distance (a point infinitesimally close to zero), and which can be easily removed with a crowbar when removing the peg. EXAMPLES

[0008] The following embodiment will be described with reference to the attached drawings. [Figure 1] is an overall view of a peg with a groove (projection) according to the present invention. [Figure 2] is a view from the top of the tip. [Figure 3] is a view of the peg from the bottom. [Figure 4] is an example of an ideal peg being driven in, and when driven in as in [Figure 5], due to the principle of leverage (there is a distance between the fulcrum, the force point, and the action point in the figure), there is a risk that the peg will easily come out even with a weak force, as in [Figure 6]. [Figure 7] is a view of the peg of the present invention driven in about 1 / 2. [Figure 8] is a view of the peg of the present invention driven in about 2 / 3, but in either case, the string is always on the ground, so due to the principle of leverage (the distance between the fulcrum and the force point is almost zero), the peg is very difficult to remove. Also, when removing a peg, it is possible to use a crowbar in a position where the fulcrum of the crowbar is always on the ground, regardless of how far the peg is driven in, as in [Figure 9], [Figure 10], and [Figure 11].
