請參閱美國專利US2017/0241463A1之「HOLE EXPANDING SCREW」、美國專利US2013/0039720A1之「SCREW」、歐洲專利EP1411252A2之「Screw to be used with building elements made of wood」及台灣專利TW201544718A之「螺絲」等專利前案，該等專利前案揭露之現有螺絲結構皆主要包含有一端頭，及一與端頭相連接而末端呈尖錐端之桿體，而其桿體由其尖錐端至端頭係呈同一直徑，並使該桿體沿其長度向成型有由尖錐端螺旋往上之鎖合螺紋，又於該同一直徑之桿體上成型有數呈斜向或直向排列而為連續或非連續設立之鑽削單元，其中，該美國專利US2017/0241463A1之螺絲係揭示於其同一直徑之桿體上成型有直向排列而呈非連續設立之鑽削單元［Fig.2B之編號221〕，又美國專利US2013/0039720A1之螺絲則揭示於其同一直徑之桿體上成型斜向排列呈連續設立之鑽削單元［Fig.1之編號331〕，而歐洲專利EP1411252A2之螺絲揭示於其同一直徑之桿體上成型直向排列連續設立之鑽削單元［Fig.1之編號3〕，另台灣專利TW201544718A之螺絲則揭示於其同一直徑之桿體上成型有直向排列呈連續設立之鑽削單元［圖1之編號4〕及直向排列呈非連續設立之鑽削單元［圖4之編號4〕。藉此，當該螺絲與工件鎖接時，係使其桿體的尖錐端抵設於木材等工件上，再施力旋轉該螺絲，以使其尖錐端鑽入工件，並藉由其鑽削單元對工件鑽孔，隨之鎖合螺紋係接續螺入形成內螺紋段。Please refer to the "HOLE EXPANDING SCREW" of US Patent US2017/0241463A1, the "SCREW" of US Patent US2013/0039720A1, the "Screw to be used with building elements made of wood" of European Patent EP1411252A2 and the "Screw" of Taiwan Patent TW201544718A. In the previous cases, the existing screw structures disclosed in the previous patent cases mainly consist of one end and a rod connected to the end with a tapered end, and the rod is connected from the tapered end to the end. The rod is of the same diameter, and the rod is formed along its length with a locking thread spiraling upward from the pointed cone end, and the rod of the same diameter is formed with a number of oblique or vertical arrangement, which is continuous or non-continuous. Continuously set up drilling unit. Among them, the screw of the US Patent US2017/0241463A1 is disclosed on a rod of the same diameter with straightly arranged and non-continuously set up drilling units [Fig. 2B No. 221], In addition, the screw of the US patent US2013/0039720A1 discloses a continuous drilling unit formed obliquely arranged on a rod of the same diameter [No. 331 in Fig.1], and the screw of the European patent EP1411252A2 is disclosed in the same diameter. Drilling units are formed on the rod body in a straight arrangement [No. 3 in Fig.1], and the screw of Taiwan Patent TW201544718A reveals that a rod of the same diameter is formed with a drill unit arranged in a straight direction and arranged continuously. [No. 4 in Figure 1] and a non-continuously arranged drilling unit [No. 4 in Figure 4]. Thereby, when the screw is locked with the workpiece, the pointed end of the rod body is pressed against the workpiece such as wood, and then the screw is rotated by force to make the pointed end of the screw penetrate into the workpiece, and the The drilling unit drills a hole on the workpiece, and then the lock thread system is continuously screwed to form an internal thread section.
然，該上述專利前案揭示之螺絲為了降低旋入扭力，皆使其鑽削單元外徑大於鎖合螺紋底徑，故其鑽削單元鑽削而成的工件螺孔內徑也大於鎖合螺紋底徑，以致造成鎖合螺紋與工件之內螺紋段咬合度不佳等缺失，降低螺絲與工件的結合強度。再者，由於上述專利前案揭露之螺絲其鑽削單元皆成型於同一直徑之桿體上，於此設計當其桿體所設鑽削單元於螺鎖過程中，僅能破壞桿體外周的工件材料，而使桿體其體積外圍產生擴孔，因此，當鎖合螺紋將桿體旋入工件時，工件材料係呈被壓縮狀態而密度提高，隨著密度提高，螺絲旋入所受阻力相對增加，必須施加更大扭力才可將螺絲鎖入工件內，又由於其鑽削單元係與鎖合螺紋成型於同一直徑桿體上，隨著桿體截面積越大，其鑽削單元於鑽削工件的過程中所受阻力也越大，施工者亦須耗費更多力氣，才可將螺絲鎖入工件中，以致減損現有螺絲與工件鎖接順暢性。However, in order to reduce the screwing torque of the screw disclosed in the aforementioned patent, the outer diameter of the drilling unit is larger than the bottom diameter of the lock thread, so the inner diameter of the workpiece screw hole drilled by the drilling unit is also larger than the lock The bottom diameter of the thread causes the lack of good bite between the locking thread and the internal thread section of the workpiece, which reduces the bonding strength of the screw and the workpiece. Furthermore, since the drilling units of the screws disclosed in the previous patents are all formed on a rod of the same diameter, this design can only damage the outer periphery of the rod when the drilling unit is set on the rod during the screwing process. The material of the work piece, and the volume of the rod body is enlarged. Therefore, when the screw body is screwed into the work piece by the lock thread, the work piece material is in a compressed state and the density increases. As the density increases, the resistance of the screw is relatively Increase, more torque must be applied to lock the screw into the workpiece, and because the drilling unit and the locking thread are formed on the same diameter rod, as the cross-sectional area of the rod becomes larger, the drilling unit is The greater the resistance in the process of cutting the workpiece, the more effort must be spent by the constructor to lock the screw into the workpiece, so as to reduce the smoothness of the existing screw and the workpiece.
緣是，本發明人有鑑於現有螺絲於使用上仍有上述缺失，乃藉其多年於相關領域的製造及設計經驗和知識的輔佐，並經多方巧思，研創出本發明。The reason is that, in view of the above-mentioned shortcomings in the use of existing screws, the inventors developed the present invention with the assistance of many years of manufacturing and design experience and knowledge in related fields, and through many ingenuities.

This is the wood screw structure of the present invention. It mainly includes one end (1) and a rod (2) integrally connected with the end (1). The rod (2) ) Includes a main pole section (21) and a bundle tail section (22), so that the main pole section (21) and bundle tail section (22) are each formed with a first end and a second end opposite to each other. The first end of the main rod section (21) faces the end (1), and the second end of the main rod section (21) is connected with the first end of the beam tail section (22), and the beam tail section ( 22) The second end forms a pointed end (221), and the diameter [D1] of the beam tail section (22) is smaller than the diameter of the main rod section (21) [D2], please refer to the second and third drawings together As shown, in addition, the main rod section (21) is formed with a first locking thread (23) spirally extending from the second end to the first end direction, and a first locking thread (23) is formed on the beam tail section (22). The second locking thread (24) spirally extending from the second end to the first end, so that the second locking thread (24) is connected with the first locking thread (23), and the bundle tail section (22) The diameter [D1] forms the bottom diameter of the second locking thread (24), and the diameter [D2] of the main rod section (21) forms the bottom diameter of the first locking thread (23). The tail section (22) is formed with a plurality of drilling units (25) which are arranged obliquely from the second end to the first end and are continuously established. The continuously established drilling units (25) straddle the second lock At least one pitch [p] of the thread (24), please refer to the figures 4~6 together, and make the outer diameter [D3] of the drilling unit (25) smaller than the outer diameter of the second locking thread (24) [D4], and make the outer diameter [D4] of the second locking thread (24) smaller than the outer diameter of the first locking thread (23) [D5], please refer to the seventh figure together, and make the drill The tooth height [h1] of the cutting unit (25) is less than or equal to 0.9 times the tooth height [h2] of the second locking thread (24).
據此，當本發明之木螺絲與木材、壓合板等工件螺接鎖固時，係將本發明之木螺絲其束尾段（２２）之尖錐端（２２１）抵設於工件上，再以螺絲起子等工具旋動該端頭（１），以帶動該束尾段（２２）轉動，而使其尖錐端（２２１）鑽入工件，並藉由該束尾段（２２）上所設鑽削單元（２５）對工件材料產生徑向破壞，由於束尾段（２２）上之鑽削單元（２５）預先破壞相對應於主桿段（２１）之工件材料，故主桿段（２１）藉由第一鎖合螺紋（２３）螺鎖塞入工件的體積雖然不變，然由於工件在相應主桿段（２１）的位置已被束尾段（２２）上之鑽削單元（２５）等破壞，而使工件材料變得鬆散、密度降低，如此，即可減少主桿段（２１）之第一鎖合螺紋（２３）於螺鎖過程由於材料堆積所需克服的反向應力，進而減輕本發明之木螺絲鎖入工件時所需施加的扭力，以提高木螺絲與工件鎖接順暢性。According to this, when the wood screw of the present invention is screwed and locked to a workpiece such as wood and a press plate, the pointed end (221) of the tail section (22) of the wood screw of the present invention is pressed against the workpiece, and then Rotate the end (1) with a screwdriver or other tools to drive the end of the beam (22) to rotate, so that the pointed end (221) is drilled into the workpiece, and the end (22) is placed on the end of the beam (22). Set the drilling unit (25) to produce radial damage to the workpiece material. Because the drilling unit (25) on the beam tail section (22) pre-destructs the workpiece material corresponding to the main rod section (21), the main rod section ( 21) Although the volume of the workpiece inserted into the workpiece by the first locking thread (23) is unchanged, the position of the workpiece in the corresponding main rod section (21) has been bound by the drilling unit (22) on the tail section (22). 25) The material of the workpiece becomes loose and the density decreases. In this way, the first locking thread (23) of the main rod section (21) can be reduced during the screw locking process due to the material accumulation. Therefore, the torsion force required to be applied when the wood screw of the present invention is locked into the workpiece is reduced, so as to improve the smoothness of the wood screw and the workpiece.
再者，由於本發明之木螺絲係使其鑽削單元（２５）外徑［D3〕小於第二鎖合螺紋（２４）外徑［D4〕，又使該第二鎖合螺紋（２４）外徑［D4〕小於其第一鎖合螺紋（２３）外徑［D5〕，故隨著束尾段（２２）之第二鎖合螺紋（２４）與主桿段（２１）之第一鎖合螺紋（２３）於鑽削單元（２５）鑽削形成之孔洞的接續螺入，係可使工件之內螺紋的牙深越為加深，而形成與該主桿段（２１）之第一鎖合螺紋（２３）其牙高相匹配對應咬合之內螺紋段，依此，以提高本發明之木螺絲與工件鎖接結合的穩固性。Furthermore, because the wood screw of the present invention makes the outer diameter [D3] of the drilling unit (25) smaller than the outer diameter [D4] of the second locking thread (24), the outer diameter [D4] of the second locking thread (24) The diameter [D4] is smaller than the outer diameter [D5] of the first locking thread (23), so the second locking thread (24) of the tail section (22) and the first locking of the main rod section (21) The thread (23) is continuously screwed into the hole formed by the drilling unit (25), which can make the thread depth of the internal thread of the workpiece deeper and form the first lock with the main rod section (21) The thread (23) matches the internal thread segment of the corresponding occlusal thread height, so as to improve the stability of the locking combination of the wood screw and the workpiece of the present invention.
前述之實施例或圖式並非限定本發明之木螺絲結構實施態樣，本發明之鑽削單元（２５）除可呈斜向排列連續設立外，請一併參閱第八圖所示，該鑽削單元（２５）亦可為由束尾段（２２）第二端往第一端呈直向排列之非連續設立的鑽削單元（２６），該非連續設立的鑽削單元（２６）係成型於該第二鎖合螺紋（２４）之至少一螺距［p〕間。另請一併參閱第九圖所示，本發明也可使該鑽削單元（２７）呈斜向排列之非連續設立，或者請一併參閱第十圖所示，令該鑽削單元（２８）呈直向排列之連續設立等型態，依此，同樣可達到使該等鑽削單元（２６）、（２７）、（２８）將工件材料預先破壞，以減輕主桿段（２１）之第一鎖合螺紋（２３）鎖入工件時所需扭力，提高木螺絲與工件鎖接順暢性等效益，凡所屬技術領域中具有通常知識者所為之適當變化或修飾，皆應視為不脫離本發明之專利範疇。The foregoing embodiments or drawings do not limit the implementation of the wood screw structure of the present invention.
