Description
【0001】[0001]
この考案は、たとえば、家具の製造などにおいて木製板相互をL字状やT字状 あるいは直線状などに、釘目を見せない状態で接合するような、めくら釘に関す る。 The present invention relates to a blind nail that joins wooden boards to each other in an L-shape, a T-shape, or a straight shape in a state where nails are not shown in the manufacture of furniture, for example.
【0002】[0002]
板同士を直線状に、しかも釘目を見せないで接合する手段の一つとして木製の めくら釘がある。このめくら釘は円柱状で外周面にゆるい螺旋を切った構造であ って、接合面にあらかじめ形成した圧入孔に接着剤を充填し、あるいはめくら釘 に接着剤を塗布したのち圧入孔にめくら釘を圧入して使用する。 There is a wooden blind nail as one of the means for joining the plates in a straight line and without showing the nails. This blind nail has a columnar structure with a loose spiral cut on the outer peripheral surface.Adhesive is filled in a press-fitting hole that has been formed in advance on the joint surface, or adhesive is applied to the blind nail and then the blind is inserted into the press-fitting hole. Use by pressing in nails.
【0003】[0003]
すなわち、めくら釘の外周面に切った螺旋は、接着剤を全体に回すためのもの であって、積極的な抜止め作用はない。このため、接着剤の充填や塗布が不充分 であったり、完全に接着剤を乾燥しなかったなどの場合には接合不良状態になり 、商品価値がなくなってしまう。 That is, the spiral cut on the outer peripheral surface of the blind nail is for turning the adhesive all over, and does not have a positive retaining action. For this reason, if the adhesive is not sufficiently filled or applied, or if the adhesive is not completely dried, a poor joint will result and the commercial value will be lost.
【0004】 しかも手数が多く、また接着剤を乾燥させる時間を充分にとる必要があるので 、接合作業に手間が掛るという難点もある。In addition, there is a problem that it takes a lot of time and that it takes a lot of time to dry the adhesive, which makes the joining work troublesome.
【0005】 そこでこの考案は、高い接合保持力を有し、しかも簡易迅速に接合作業が行な るめくら釘の提供を課題とする。[0005] Therefore, an object of the present invention is to provide a blind nail which has a high joint holding force and can perform a joining work easily and quickly.
【0006】[0006]
上述した課題を解決するための手段を実施例の図1を用いて説明すると、その 構成は、相接合する木材1,2の接合面1a,2a間に介装固定して釘目を隠し た状態で両木材を接合するめくら釘であって、上記めくら釘を金属製で中空の筒 状体4で形成するとともに、該筒状体4の各木材1,2に打ち込まれる打ち込み 相当部位4a,4a周面に、上記筒状体4の軸方向からの圧縮によって***し、 木材1,2内に食込む食込み部6…を形成しためくら釘3であることを特徴とす る。 The means for solving the above-mentioned problems will be described with reference to FIG. 1 of the embodiment. The configuration is such that the nails are hidden by interposing and fixing between the joint surfaces 1a and 2a of the woods 1 and 2 to be phase-joined. A blind nail that joins both woods in a state, in which the blind nail is made of a metal hollow cylindrical body 4 and is hammered into each of the woods 1 and 2 of the cylindrical body 4. It is characterized in that it is a hook nail 3 which forms a biting part 6 ... which is raised by compression of the tubular body 4 in the axial direction on the peripheral surface 4a and bites into the woods 1 and 2.
【0007】[0007]
すなわち、上述の構成によれば、木材相互を接合する場合には、例えば互いの 接合面の打ち込み方向に、接合面同士を接合した状態ではめくら釘を介装できな い所定深さで、かつ嵌入することでめくら釘を保持できる程度の径を有する孔を あらかじめ形成しておき、この孔にめくら釘の打ち込み相当部位部分を嵌入した 状態にして両木材の接合面を接合する方向、換言すればめくら釘をその軸方向に 圧縮する方向に、衝撃を与えればよい。 That is, according to the above configuration, when timbers are joined together, for example, in the driving direction of the joining surfaces of the timbers, at a predetermined depth such that the blind nail cannot be inserted in the state where the joining surfaces are joined, and A hole with a diameter that can hold the blind nail by inserting it is formed in advance, and the direction in which the joint surface of both woods is joined with the portion corresponding to the driving of the blind nail inserted into this hole, in other words, A shock may be applied in the direction of compressing the blind nail in its axial direction.
【0008】 すると、打ち込み時の振動によってめくら釘は軸方向に圧縮され、筒状体の打 ち込み相当部位周面に形成した食込み部が***して、それぞれ木材内に食込む。 そしてこのとき両木材の接合面は接合し、この接合状態を、***した食込み部が 積極的に保持する。Then, the blind nails are axially compressed by the vibration at the time of driving, and the biting portion formed on the peripheral surface of the portion corresponding to the driving of the tubular body is raised and bites into the wood. At this time, the joint surfaces of both woods are joined, and the raised biting portion positively holds this joined state.
【0009】[0009]
上述の結果、この考案によると、筒状体両側の打ち込み相当部位周面には、軸 方向に圧縮された際に***して木材内に食込む食込み部を形成しているので、木 材相互の接合完了時には積極的な抜止めが行なえる。このため、高い接合保持力 が得られ、製品の運送などの時に大きな振動を受けたとしても製品に損傷などが 起こらず、信頼性を高めることもできる。 As a result of the above, according to the present invention, the peripheral portions of the portions corresponding to the driving on both sides of the tubular body are formed with the biting portions that bulge and bite into the wood when compressed in the axial direction. When joining is completed, positive removal can be done. For this reason, a high bond holding force is obtained, and even if a large vibration is applied during transportation of the product, the product is not damaged and the reliability can be improved.
【0010】 また、木材相互の接合作業は、めくら釘を介装した後で両木材の接合面同士を 接合する方向に圧縮する動作を行なうだけでよく、また接着剤を乾燥させるよう な時間は不要であるので、接合作業が簡易迅速に行なえる。Further, the joining work of the timbers may be performed by inserting the blind nails and then compressing the joining surfaces of the timbers in the joining direction, and the time for drying the adhesive is not required. Since it is unnecessary, joining work can be performed easily and quickly.

この考案の一実施例を以下図面に基づいて詳述する。 図1は木製の板1,2の同士を接合するためのめくら釘3を示し、このめくら 釘3は図2にも示す通り中空の円筒状で、この筒状体4の両側の打ち込み相当部 位4a,4aの周面には菱形の小孔5…を複数形成して食込み部6…を設け、両 端面を蓋片7,7で封止している構造である。 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a blind nail 3 for joining wooden plates 1 and 2 together. The blind nail 3 has a hollow cylindrical shape as shown in FIG. A plurality of diamond-shaped small holes 5 ... Are formed on the peripheral surfaces of the positions 4a, 4a, and bite portions 6 ... Are provided, and both end surfaces are sealed by lid pieces 7, 7.
【0012】 このめくら釘3はプレス加工した金属板を丸めて形成するものであって、丸め る前段の基材8は図3に示すとおりである。すなわち、筒状体4に相当する長方 形部分は、その長手方向(筒状体4の軸方向)において右側と左側とに区分され ており、これらの両側部分では、短手方向(筒状体4の周方向)に沿ってそれぞ れ上述の小孔5…を3つずつ等間隔で配設している。これらの各小孔5…は、長 手方向に長い菱形である。また短手方向に並ぶ小孔5…間が、前述した食込み部 6…で、筒状体4が軸方向に圧縮された時に外周方向に折曲して***し、接合板 内に食込むものである。なお上述した折曲を容易にするため、この食込み部6… の裏面には、破線で示す折曲溝6a…を形成している。The blind nail 3 is formed by rolling a pressed metal plate, and the base material 8 in the front stage of rolling is as shown in FIG. That is, the rectangular portion corresponding to the tubular body 4 is divided into the right side and the left side in the longitudinal direction (axial direction of the tubular body 4), and the lateral direction (cylindrical direction) in these both side portions. Three small holes 5 are arranged at equal intervals along the circumferential direction of the body 4. Each of these small holes 5 is a rhombus long in the longitudinal direction. Between the small holes 5 arranged side by side in the lateral direction is the above-mentioned biting portion 6, which is bent and bulged in the outer peripheral direction when the tubular body 4 is axially compressed and bites into the joint plate. .. In order to facilitate the above-mentioned bending, bending grooves 6a shown by broken lines are formed on the back surface of the biting portions 6 ...
【0013】 上述した蓋片7,7は、筒状体4の端面に当接する大きさの円形であり、適宜 位置に連設部7a,7aを介して連設している。The above-mentioned lid pieces 7, 7 are circular in a size that abuts on the end surface of the tubular body 4, and are continuously provided at appropriate positions via the continuous portions 7 a, 7 a.
【0014】 つぎに、以上のように構成しためくら釘3の使用態様を、板1,2の端面1a ,2a同士を接合して直線状にする場合をその一例として採用し、図4ないし図 6を用いて説明する。Next, as an example of the use mode of the trapezoid nail 3 configured as described above, the case where the end faces 1a 1 and 2a of the plates 1 and 2 are joined to form a straight line is adopted as shown in FIG. This will be described using 6.
【0015】 図4に示すように、相接合する板1,2の端面1a,2a(接合面)には、上 下両面を面一にする対向位置に、打ち込み方向に沿う嵌入孔1b,2bをあらか じめ形成している。 これらの嵌入孔1b,2bは、使用前のめくら釘3の半分の長さよりも浅い所 定深さに設定し、またその径は、食込み部6…を***させないでめくら釘3の嵌 入が行なえ、かつ嵌入しためくら釘3を保持できるような圧力を有するように設 定している。As shown in FIG. 4, the end faces 1a and 2a (joint faces) of the plates 1 and 2 to be phase-joined are fitted into the insertion holes 1b and 2b along the driving direction at opposing positions where the upper and lower surfaces are flush with each other. Is formed in advance. These fitting holes 1b, 2b are set to a predetermined depth shallower than half the length of the blind nail 3 before use, and the diameter thereof allows the blind nail 3 to be fitted without raising the biting portion 6 ... It is designed to have a pressure so that it can be inserted and hold the trapezoid nail 3 when it is inserted.
【0016】 接合作業はまず、めくら釘3両側の打ち込み相当部位4a,4aを手で、ある いは適宜の治具を用いて両板1,2の嵌入孔1b,2bに嵌入し、図5に示す状 態にする。 そしてその後、同図に白抜き矢印で示すごとく、両板1,2を互いの接合面1 a,2aを接合する方向、すなわち、めくら釘3を軸方向に圧縮する方向に一挙 に圧力をかける。 すると図6に示すように、めくら釘3の打ち込み相当部位4a,4aに形成し た食込み部6…に対して小孔5…部分で回避された圧縮による圧力が集合する。 そして、この食込み部6…が折曲させられて***し、板1,2内に食込み、同時 に両板1,2の端面1a,2aを互いに接合させてこの状態を保持する。In the joining operation, first, the driving-corresponding parts 4a, 4a on both sides of the blind nail 3 are fitted into the fitting holes 1b, 2b of the both plates 1 and 2 by hand, or by using an appropriate jig, as shown in FIG. Set to the state shown in. After that, as indicated by the white arrow in the figure, pressure is applied all at once in the direction of joining the joint surfaces 1a, 2a of the plates 1 and 2, that is, in the direction of compressing the blind nail 3 in the axial direction. .. Then, as shown in FIG. 6, the pressure caused by the compression avoided at the small holes 5 ... Collects against the biting portions 6 ... Formed in the driving nail corresponding portions 4a, 4a. Then, the biting parts 6 are bent and raised so as to bite into the plates 1 and 2, and at the same time, the end faces 1a and 2a of the plates 1 and 2 are joined to each other to maintain this state.
【0017】 このように板1,2の接合時には、食込み部6…が板1,2内に食込んでその 接合状態を積極的に保持するので、高い接合保持力が得られる。このため、例え ば製品の運送などの時に大きな振動を受けたとしても製品に損傷などが起こらず 、信頼性を高めることができる。As described above, when the plates 1 and 2 are joined, the biting portions 6 bite into the plates 1 and 2 to positively maintain the joined state, so that a high joining holding force can be obtained. Therefore, even if a large vibration is applied to the product during transportation, the product will not be damaged and the reliability can be improved.
【0018】 また、板1,2相互の接合作業はめくら釘を介装した後で両板1,2の接合面 同士を接合する方向に圧縮する動作を行なうだけでよいので、接合作業は簡単に 行なえる。Further, the joining work of the plates 1 and 2 is simple because the operation of compressing the joining faces of the plates 1 and 2 in the joining direction after inserting the blind nail is simple. Can be done.
【0019】 なお、上述の一実施例では筒状体を円筒状に形成したが、四角柱状などに設定 し、小孔を直角部分に行なうようにするもよい。 また、小孔5…の形状は図7に示すように楕円形であるも、または円形などで あるもよい。 さらに、接合作業を正確に行なうようにするため、例えば筒状体の外周面に嵌 入孔に対する完全なる嵌入が行なわれたことを示す目印を形成するようにするも よい。Although the tubular body is formed in a cylindrical shape in the above-described embodiment, it may be formed in a rectangular column shape or the like so that the small hole is formed at the right angle portion. Further, the shape of the small holes 5 ... May be elliptical as shown in FIG. 7, or may be circular or the like. Further, in order to perform the joining work accurately, it is possible to form a mark on the outer peripheral surface of the tubular body, for example, which indicates that the fitting hole is completely fitted.
