Description

[Technical Field]

[0001] The embodiments disclosed in this specification relate to a bolt comprising a head portion and a threaded portion, and more particularly to a bolt having an opening that allows the height of the head portion to be reduced by providing the opening. [Background technology]

[0002] Normally, Bolt is Kunimi Use model application Disclosed in 1999-0009107 As shown in the figure, the screw part has a thread formed on the outer periphery, and one side of this screw part has various and a head portion that can be coupled to the tool.

[0003] Such a conventional bolt has a tool coupling groove formed in the head portion, into which a tool such as a screwdriver or wrench is coupled, and the head portion and threaded portion are rotated by the tool, and the threaded portion is fastened to a structure such as a nut or directly fastened to the base material of a wooden structure to be fixed.

[0004] Here, in order to stably connect a tool to a bolt, the depth of the tool connection groove must be ensured to have a predetermined size, and therefore the head portion must also be ensured to have a predetermined height.

[0005] Of course, if the tool coupling groove is extended to the threaded portion, the height of the head portion can be made lower, but in this case, there is a problem that the thickness of the threaded portion must be greater than or equal to the thickness of the tool.

[0006] In addition, in a conventional bolt, the tool is completely accommodated in the tool coupling groove, so there is a problem in that the tightening state of the head portion cannot be detected by the tool.

[0007] In addition, with conventional bolts, the head cannot be fixed to the structure after the threaded portion is fastened to the structure, so there is a problem that the threaded portion may reverse and become loose if vibration or impact is repeatedly applied.

[0008] Therefore, there is a need for a new technology to overcome the limitations of the prior art.

[0009] On the other hand, the above-mentioned background art is technical information that the inventor possessed for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and it cannot necessarily be said to be publicly known art that was disclosed to the general public prior to the filing of the present invention.

[0010] [Patent Document 1] Korean Utility Model Application No. 1999-0009107 Summary of the Invention [Problem to be solved by the invention]

[0011] The embodiments disclosed in this specification aim to provide a bolt with an opening that allows the height of the head portion to be made relatively low without forming the threaded portion thick, by forming an opening in a part of the coupling groove to which the tool is coupled that allows part of the tool to be exposed.

[0012] Furthermore, the embodiments disclosed in this specification aim to provide a bolt with an opening that allows a part of a tool to protrude through the opening formed in the coupling groove, so that the fastening state of the head can be sensed through the protruding part.

[0013] Furthermore, the embodiments disclosed herein aim to provide a bolt with an opening that can prevent the head from loosening arbitrarily by fixing it in a fully tightened state. [Means for solving the problem]

[0014] As a technical means for achieving the above-mentioned technical object, one embodiment of a bolt with an opening comprises a head portion and a threaded portion, and is fastened to a structure via the threaded portion as the bolt is rotated by a tool. The bolt includes a coupling groove having a cross-sectional groove shape corresponding to the tool and formed in the head portion or the threaded portion to allow the tool to be coupled, and an opening formed in the shape of a hole in a part of the coupling groove to expose at least a part of the tool coupled to the coupling groove to the outside of the head portion or the threaded portion.

[0015] The coupling groove may include an entrance portion formed in the head portion and serving as an entrance for accommodating the tool, and an accommodating portion extending from the entrance portion toward the threaded portion to accommodate the tool, penetrating the head portion and extending to the threaded portion, with the opening formed in a portion thereof.

[0016] The opening may be formed in a part of the receiving portion and at a boundary between the head portion and the threaded portion.

[0017] In addition, the inlet portion may be formed to have a width greater than that of the threaded portion, and the receiving portion may extend at a predetermined inclination angle so that the width gradually decreases from the inlet portion toward the threaded portion.

[0018] The opening may be formed on the inclination of the receiving portion and at the boundary between the head portion and the threaded portion.

[0019] In addition, the storage portion is formed such that the inclination angle crosses the boundary between the head portion and the threaded portion, and extends through the opening, and the opening can expose a portion of the tool that is coupled along the inclination of the storage portion in a state where it protrudes outside the head portion and the threaded portion.

[0020] In addition, the bolt may further include at least one stop protrusion protruding from the bottom surface of the head portion and tightly engaging with a structure when the threaded portion is fastened, thereby preventing the threaded portion from coming loose. [Effects of the Invention]

[0021] According to any one of the above-mentioned means for solving the problems, the receiving portion that forms the coupling groove to which the tool is coupled extends at an angle that intersects the boundary between the head portion and the thread portion, and an opening is formed at the boundary between the head portion and the thread portion, so that the height of the head portion can be relatively lower than conventional bolts, thereby saving material and reducing the volume and weight, and a bolt with an opening can be provided.

[0022] In addition, by using any one of the above-mentioned problem-solving means, foreign matter that flows into the coupling groove can be discharged through the opening, and it is also expected that the hot air that is applied to the head portion can be dissipated through the opening.

[0023] Furthermore, according to any one of the above-mentioned problem-solving means, a bolt with an opening can be presented in which a part of the tool protrudes through the opening, and when the head is tightened, the protruding part of the tool comes into contact with the structure first, so that the tightening state of the head can be sensed via the tool.

[0024] In addition, by using any one of the above-mentioned solutions to the problem, it is possible to expect the effect that after the head portion is fastened, adhesive can be injected through the opening to fix the head portion to the structure.

[0025] In addition, by using any one of the above-mentioned problem-solving means, the retaining protrusions formed on the bottom surface of the head portion are tightly attached to the structure, which is expected to have the effect of preventing the head portion from coming undone arbitrarily.

[0026] The effects obtained by the disclosed embodiments are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art to which the disclosed embodiments pertain from the following description. [Brief explanation of the drawings]

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various forms and is not limited to the embodiments described herein. In order to clearly explain the present invention in the drawings, parts that are not relevant to the description are omitted, and similar parts are designated by similar reference numerals throughout the specification.

[0029] Throughout this specification, when a certain component is said to be "connected" to another component, this includes not only "directly connected" but also "indirectly connected" via another element in between. Furthermore, when a certain part is said to "include" a certain component, this does not mean that it excludes other components, but that it may also include other components, unless otherwise specified.

[0030] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings.

[0031] Fig. 1 is a perspective view showing a bolt with an opening according to one embodiment, Fig. 2 is a longitudinal cross-sectional view showing a bolt with an opening according to one embodiment, Fig. 3 is a front view showing a state in which a tool is coupled to the bolt with an opening according to one embodiment, Fig. 4 is a cutaway perspective view showing a main part of the bolt with an opening according to one embodiment, and Fig. 5 is a bottom perspective view showing a bolt with an opening according to another embodiment.

[0032] As shown in Figures 1 and 2, a bolt 10 with an opening according to one embodiment is a component that consists of a head portion 1 and a threaded portion 2, and is fastened to a structure via the threaded portion 2 while being rotated by a tool 3 such as a screwdriver.

[0033] Such an apertured bolt 10 may comprise a coupling groove 100 and an aperture 200 .

[0034] The coupling groove 100 is a component that provides a coupling portion for the tool 3, and is formed in a groove shape corresponding to the tool 3 so that the tool 3 can be inserted and coupled.

[0035] For example, the coupling groove 100 may be formed to have a cross section in the shape of a plus sign to allow coupling with a plus sign driver, as shown in Figure 1, or may be formed to have a cross section in the shape of a minus sign to allow coupling with a minus sign driver, as shown in Figure 1. In addition, the coupling groove 100 may be formed to have a cross section in a shape corresponding to a polygonal wrench.

[0036] That is, the coupling groove 100 can be formed in a shape corresponding to the tool, regardless of the type of tool.

[0037] Such a coupling groove 100 can be formed in the head portion 1 as shown in Figures 1 and 2, or, unlike the illustration, can be formed in the threaded portion 2 to allow coupling with a tool 3.

[0038] A bolt 10 with an opening according to one embodiment can be configured in a form in which a coupling groove 100 extends across both the head portion 1 and the threaded portion 2, as shown in FIG.

[0039] Specifically, the coupling groove 100 may include an inlet portion 110 and a receiving portion 120, as shown in FIG.

[0040] The inlet portion 110 is a component forming an inlet of the coupling groove 100 for receiving the tool 3 and can be formed in the head portion 1 .

[0041] Such an inlet portion 110 may be formed to have a width corresponding to the width of the tool 3, and preferably may be formed to have a width wider than the width of the threaded portion 2 as shown in FIG. 2, but is not limited thereto.

[0042] The receiving portion 120 is a component that extends from the inlet portion 110 toward the threaded portion 2 and receives the tool 3 that is coupled through the inlet portion 110 .

[0043] Such a storage section 120 extends from the entrance section 110 toward the screw section 2, and can extend through the head section 1 to the screw section 2, and an opening 200 described later is formed in part of it, allowing part of the tool 3 to be exposed.

[0044] Here, the receiving portion 120 can be extended to have a width corresponding to the width of the tool 3 .

[0045] For example, the receiving portion 120 may have the same width as the entrance portion 110 and extend to the threaded portion 2, or may extend at a predetermined inclination angle so that the width gradually decreases as it moves from the entrance portion 110 toward the threaded portion 2.

[0046] In particular, when the width of the inlet portion 110 is formed to be greater than the width of the threaded portion 2, as shown in FIG. 2, the receiving portion 120 may extend obliquely so that its width gradually decreases toward the threaded portion 2, and may extend to the threaded portion 2 with a width smaller than the width of the threaded portion 2.

[0047] The opening 200 is formed in the shape of a hole in a part of the coupling groove 100 as shown in FIG. 2, and is a component that exposes at least a part of the tool 3 coupled to the coupling groove 100 to the outside of the head portion 1 or the screw portion 2 as shown in FIG. 3.

[0048] In other words, the opening 200 connects part of the coupling groove 100 to the outside, thereby exposing part of the tool 3, and is expected to have the effect of expelling foreign matter that has flowed into the coupling groove 100 or dissipating hot air that is applied to the head portion 1.

[0049] Furthermore, the opening 200 can also allow an adhesive to be poured in after the screw portion 2 has been fastened, thereby fixing the head portion 1 or the screw portion 2 to the base material of the structure.

[0050] The opening 200 is formed in the receiving portion 120 forming the coupling groove 100 and can be drilled in the head portion 1 or the threaded portion 2 .

[0051] Here, when the opening 200 is drilled in the head portion 1 or the screw portion 2, it can expose a portion of the tool 3 stored in the storage portion 120 in a see-through manner, but it cannot expose the tool 3 in a state where it protrudes outside the head portion 1 or the screw portion 2.

[0052] Meanwhile, the opening 200 is formed in the receiving portion 120, and may be drilled at the boundary between the head portion 1 and the thread portion 2 as shown in FIGS.

[0053] Here, when the accommodating portion 120 extends at an inclined angle in which its width gradually decreases in the direction of the screw portion 2 and at an angle that crosses the boundary between the head portion 1 and the screw portion 2, the opening 200 can be drilled at the boundary between the head portion 1 and the screw portion 2 to connect the inclined surface of the accommodating portion 120.

[0054] That is, the receiving portion 120 can extend through the opening 200 at an oblique angle across the boundary between the head portion 1 and the thread portion 2 .

[0055] In this case, as the tool 3 is coupled along the inclined surface of the accommodating portion 120, a portion of the tool 3 may be exposed and protrude outside the head portion 1 and the screw portion 2, as shown in FIG.

[0056] Therefore, as shown in FIG. 6, the bolt 10 with an opening according to one embodiment can have a relatively lower height of the head portion 1 while having a relatively larger depth of the coupling groove 100 compared to the conventional bolt 5.

[0057] Such an opening 200 can be applied regardless of the shape of the head portion 1, such as a flat head bolt as shown in Figure 6(a) or a round head bolt as shown in (b), to make the height of the head portion 1 relatively low.

[0058] In addition, the tool 3 is exposed protruding to the outside through the opening 200, so that when the screw portion 2 is fastened to the structure, it can directly contact the surface of the structure and sense that the fastening of the screw portion 2 is complete.

[0059] Of course, the opening 200 can be drilled at the boundary between the head portion 1 and the threaded portion 2 when the accommodating portion 120 extends with the same width as the inlet portion 110, or when the accommodating portion 120 extends at an angle that does not cross the boundary between the head portion 1 and the threaded portion 2. In this case, the opening 200 is drilled at the boundary between the head portion 1 and the threaded portion 2, and a part of the tool 3 can be exposed so as to be visible through the opening 200, but the tool 3 cannot be exposed in a state where it protrudes outside the head portion 1 or the threaded portion 2.

[0060] Meanwhile, the bolt 10 with an opening according to one embodiment may further include a stop protrusion 500 as shown in FIG.

[0061] The stop protrusion 500 is a component for preventing the completely fastened screw portion 2 from coming loose.

[0062] Specifically, multiple locking protrusions 500 can protrude from the bottom surface of the head portion 1, and when the screw portion 2 is tightened, they are tightly attached to the base material of the structure, thereby preventing the head portion 1 from rotating arbitrarily.

[0063] Here, the retaining projection 500 can protrude from the bottom surface of the head portion 1 with a wedge-shaped cross section, and can protrude in the direction opposite to the tightening direction of the screw portion 2.

[0064] In this case, the locking protrusion 500 protrudes in the opposite direction to the tightening direction of the screw portion 2 and engages with the base material of the structure, thereby restricting the rotation of the head portion 1 and preventing the screw portion 2 from loosening even when vibrations or impacts are repeatedly applied to the head portion 1.

[0065] On the other hand, the locking projection 500 may have a wedge-shaped cross section and project in a direction corresponding to the tightening direction of the screw portion 2 .

[0066] In this case, the stop projection 500 projects in the forward direction of the tightening direction of the screw portion 2 and faces the surface of the structure when the screw portion 2 is fastened, thereby stopping the rotation of the screw portion 2.

[0067] The use and effects of the bolt 10 having an opening according to one embodiment including the above-described components will now be described.

[0068] The screw portion 2 can be fastened to a structure while being rotated by a tool 3 coupled to the coupling groove 100 of the head portion 1.

[0069] Here, the tool 3 is coupled to the coupling groove 100, and with a portion of it protruding through the opening 200, the head portion 1 and the screw portion 2 can be rotated, and the screw portion 2 can be directly contacted with the surface of the structure during the process of being fastened to the structure, thereby detecting that the fastening of the screw portion 2 is complete.

[0070] Furthermore, the height of the head portion 1 is relatively reduced due to the opening 200, so that the volume of the attachment portion can be reduced.

[0071] Here, the head part 1 is fixed in a state of being hung on the surface of the structure by the stopper protrusions 500 protruding from the bottom surface, and thus can be prevented from coming loose at will.

[0072] Meanwhile, after the head part 1 is completely fastened to the structure, adhesive is injected through the opening 200, so that the head part 1 can be fixed in a fastened state to the structure.

[0073] As described above, in the bolt 10 with an opening according to one embodiment, the receiving portion 120 that forms the coupling groove 100 extends at an angle that intersects the boundary between the head portion 1 and the thread portion 2, and the opening 200 is formed at the boundary between the head portion 1 and the thread portion 2. Therefore, by making the height of the head portion 1 relatively low, it is possible to save material during manufacturing and reduce the volume and weight.

[0074] The above-described embodiments are for illustrative purposes only, and those skilled in the art will understand that the above-described embodiments may be easily modified into other specific forms without changing the technical ideas or essential features of the above-described embodiments. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. For example, each component described as a single component may be implemented in a distributed form, and similarly, each component described as a distributed component may be implemented in a combined form.
