The present invention relates to connector, this connector is used for cross-connecting board, and rod member is connected to by framework, on the vertical plane that wall forms.
In recent years, clothing kitchen, bookshelf and the similar existing object that has comprise packaging, and they are provided with so-called knock-down fastener so that assembled by the envoy.In this packaging bookshelf or similar item, the screw that is referred to as to call connector is used to the link daughter board, and this Frame plate is arranged on the side direction of the frame plate that vertical direction is provided with.
As shown in figure 22, screw 2 is screwed into the cross-connecting board 3 as Frame plate more specifically, and screw 2 is to pass the hole that is formed in advance on the frame plate 1, passes the end face of cross-connecting board then, is screwed into from the outside of the frame plate 1 that forms vertical plane.
Yet this screw can be used for the situation of left and right two frame plates 1 with the method that cross-connecting board 3 is connected on the frame plate 1, but can not be used for the situation that three or more frame plates 1 are arranged abreast.
In other words, the bookshelf of big molded dimension also comprises the three or more frame plates 1 to be arranged in parallel, and can not tighten up as separable with this.
On the other hand, in recent house, bookshelf or similar item common combinations structure, they are tufted in the wall.But this combined bookshelf or similar item are installed and cross-connecting board 3 are connected under the situation on the vertical plane that frame plate 1 forms in this stake formula, adopt so-called nail mode, promptly as connector cross-connecting board 3 is connected on the frame plate 1 with nail 4.
This nail mode also can be used for the situation of the three or more frame plate 1 that is arranged in parallel, and cross-connecting board 3 is arranged between the contiguous frame plate.
Yet, in this case, drive in because nail 4 is soffits from each cross-connecting board 3, and be to drive in obliquely, this is not easy with regard to the work that produces nail and drive in, and is difficult to guarantee to prevent that cross-connecting board 3 breaks away from combination from frame plate, also promptly is difficult to guarantee durability.
With above-mentioned viewpoint, to use under the situation of nail 4, the support member 5 of metal is arranged between the medial surface of each cross-connecting board 3 downside and each frame plate 1, and is indicated as imaginary line among Figure 23.Or groove 1b is formed on the medial surface of each frame plate 1, and among the end embedded groove 1b of cross-connecting board 3, as among the figure shown in the imaginary line.
Yet, adopting the support member 5 or the groove 1b of above-mentioned metal, the number of job step has increased, and in recent years, finishes the cost that the operation of this pattern requires and improves, and the needs that obtain a large amount of costs of the bookshelf of this requirement or similar item are unfavorable.
In addition, the nail mode can not be used as above-mentioned knock-down device, and therefore large-scale bookshelf or similar item can not be provided with according to this removable device.
For example, be provided with under the situation of balustrade structure, the end that forms the rod member of handrail is connected on the vertical plane such as wall or similar item, as shown in figure 24 with a stake mounting means.So far do not have the alternate manner will be with the end face of the handrail 7 of rod member against the wall 6 that forms vertical plane except that the nail mode, nail 4 be that the soffit from handrail drives in the aforementioned same quadrat method of pointing out.
And only used nail in this case, and durability is relatively poor, needs with separable assistant metal piece installing (and do not show), and institute thinks the armrest of acquisition requirement, and the cost of requirement is very big.
The present invention is described in conjunction with above-mentioned condition, the objective of the invention is to propose a kind of connector, and this connector can be easily with cross-connecting board, and rod member or similarity piece are connected to by framework, on the vertical plane that wall or similar item form.
In order to achieve the above object, according to the feature of connector of the present invention be, the sectional elevation on the longitudinally of axis direction is shaped as rectangle, and trapezoidal or its upper face is the pentagon that tilts on a side.Be shaped as general wedge like in the vertical section of the horizontal direction of just giving longitudinally, its pointed tip up, has the trapezoidal end, the fixture of permission such as screw is arranged in wherein reach through hole and is formed on center line and partly locates to extend along longitudinally, perhaps the eccentric part in described center line part extends along longitudinally, and the lateral surface that extends along longitudinally is provided with transition portion, this transition portion is such as depressed part, or the structure of the resistance displacement that constitutes between itself and other adjacent part.
What recommend is, the Embedded Division of similar tenon is formed on the end face of front, one end of this place's reach through hole is opened wide, be formed on to the reach through hole center similar tenon the Embedded Division center or with the position of center off-centre, one slit be formed on the pinnacle of general pinnacle wedge shape up distolateral on, another part, for example screw press-fits and enters described slit, therefore, distolateral can or the swelling in pinnacle of general wedge shape by distending.
Connector according to said structure, the front end of its conduct one end is held on the frame plate or similar item of the formation vertical plane that is positioned at adjacency, under this state, the reach through hole that embeds connector as the screw of fixture is used as the screw driver of instrument and it is screwed in frame plate or the similar item, therefore, connector is fixedly joined on grillage plate or the similar item.
Under this state, connector be positioned so that its pointed tip up.
In order further to guarantee the connection status of connector for frame plate or similar item, the embedded part of similar tenon is formed on the front end face as connector one end face.Described embedded part for example is loaded in the circular hole on frame plate or similar item.
Owing to the shape of the embedded part of the similar tenon that forms is different from the cylindrical revolution that is difficult to, when described embedded part embedded hole or similar opposite position, connector can prevent the rotation of himself.
In this connection, when the reach through hole of connector is formed on the center line part of connector and lengthwise when extending, importantly heart is opened embedded part in the reach through hole, and when the position of reach through hole was eccentric in the center line part, the one end was opened in the position that is eccentric in the embedded part center.
Therefore, when an end of reach through hole is opened the connector that becomes to be eccentric in the embedded part center and is connected on two sides of frame plate or similar item, in this case, can avoid mutually as each screw of fixture.

Based on illustrated embodiment among the figure, the present invention will be described in detail.In connector 10 of the present invention, by the vertical section shape on the longitudinally of axis direction is the rectangle (see figure 4), be shaped as the top wedge like (see figure 2) that makes progress in vertical section in a lateral direction, and the shape at the end is trapezoidal (see figure 3) with the longitudinally quadrature.
Though the connector 10 of illustrated embodiment is the plastics with relative stiffness, for example polypropylene forms, and it also can form with aluminium or similar material.Can also be used for connector by method of injection molding, also can adopt any suitable method, for example cutting.Annotating with the whole mould of mould is to have said nothing of.
Be formed so that the major diameter that the head of screw 2 embeds as a whole reach through hole 11, and in the front (left end of Fig. 3 and Fig. 4) of connector 10, reach through hole 11 has the diameter portion 11a that reduces so that be used for only embedding the body of screw 2.Reducing diameter portion 11a opens wide at the front end face of connector 10.
Though in the illustrated embodiment, transition part 13 forms the recess of the part of lateral surface 12, and they can be formed the protruding ascending part of the part of lateral surface.
The connector 10 of Gou Chenging is used as connecting cross-connecting board like this, and rod member or similarity piece make it to be connected on the vertical plane that formed by frame plate or wall or similar item or similar.In the use of connector 10, predetermined machining is applied on the cross-connecting board or similarity piece that is connected to frame plate or similar item.
The cross-connecting board 3(that is connected to frame plate 1 sees Fig. 7) situation more specifically be shown in Fig. 5 and Fig. 6, this frame plate 1 forms a vertical plane, the approximate depressed part 3a that is adapted to connector 10 shapes is formed on the downside of cross-connecting board 3.
Be used as at cross-connecting board 3 under the situation of the Frame plate of bookshelf or similarity piece, depressed part 3a is formed on four positions of cross-connecting board, and this position is the positions, front, rear, left and right.What needn't speak more is, according to the situation of adopted connector, and the number of the depressed part 3a that forms.For example constitute the rod member end portion place that holds up bar of balustrade structure, so that it is connected on the vertical plane such as wall or similarity piece, depressed part 3a is formed on the soffit place of the described end of rod member.
What recommend is, when connector 10 is inserted when embedding depressed part 3a, the depressed part of formation make the end of connector be exposed to the downside of cross-connecting board 3 and the end concordant with the cross-connecting board downside.
In this embodiment, depressed part has the protrusion 3b on the inner circumferential surface of being formed on, and protrusion 3b is loaded among the recess 3a of the lateral surface 12 that forms connector 10.
On the other hand, as shown in Figure 7, one end of connector 10, so-called its end face, be open reduce diameter portion 11a so that allow threaded portion, the place ahead as the screw 2 of fixture from this projection, thereby cause the connection of the relative vertical plane that forms by frame plate 1, and screw 2 inserts reach through hole 1 simultaneously and further with screw-driven part such as a kind of instrument it is screwed into, therefore, connector 10 is fixed on the frame plate 1.
At this moment, should make tip that connector 10 is mounted to it up certainly.
In this case, the cross-connecting board that is arranged in connector 10 tops moves in Fig. 7 direction of arrow, promptly moves down, in connector 10 is packed the depressed part 3a of cross-connecting board fully into, shown in Fig. 8 and 9.
In this case, because the shape of the depressed part 3a that forms adapts to the shape of connector 10, in depressed part 3a that connector 10 is packed into, require a big external force.Yet in this case, cross-connecting board 3 for example is a plank, and both connect relatively easily and accomplish, this forms with polypropylene because of connector, and it is the material of relative stiffness, does not just require very large external force.
In connector 10 and cross-connecting board 3 interconnect, because between connector and recess 3a, because as two recesses of transition part be encased inside the protrusion 3b of recess, therefore, it is intelligible that both integral body connects into.
By this way, connector 10 allows cross-connecting board 3, and rod member or similarity piece are connected to by frame plate, on the vertical plane that wall or similarity piece form.In order further to guarantee the connection status of 10 pairs of frame plates 1 of connector or similarity piece, recommendable is to form cylindrical tenon shape Embedded Division 14 on the end face of connector, Embedded Division 14 is the minimizing diameter portion 11a that open to reach through hole 11, shown in Figure 10 and 11.
In this case, be formed in advance on the side of frame plate 1 for the hole that Embedded Division 14 is embedded wherein with cylindrical shape part.So connector 10 is specified in advance in the installation site of frame plate 1 side.It is better than aforesaid advantage is owing to being inconvenient to of causing of the installation site of not knowing connector has been eliminated.
Structure as the connector 10 of above-mentioned embodiment can make improvements as follows.
At first, as shown in figure 12, the wedge shape of the connector in the foregoing description can be changed into similar in appearance to the trapezoidal wedge shape of not being with circular tip.
Secondly, the transition part 13 that forms recess can be made of this transition part 13a that comprises the tooth that is connected, and as shown in figure 13, perhaps this as shown in figure 14 transition part comprises the small embossment of similar dihedral ripple.
Adopt the advantage of transition part 13a or 13b to be not require that formation protrusion 3b(sees Fig. 5 and 6 in depressed part 3a), this depressed part is to be formed on cross-connecting board 3 downsides in advance.
With reference now to Figure 15 and Figure 16,, the structure of diagram connector 10 is that the cross-connecting board of being convenient to allow will be connected on the deckle board 13 separates (see figure 8) from frame plate 1.
Other system point is identical with previous embodiment, uses identical label and province and removes explanation in detail.
According to the structure of the connector 10 of present embodiment, as shown in figure 15, when from its front end side-looking it, the connector that forms wedge shape has mild gradient, mainly is to allow to be easy to remove the pinnacle side of wedge, corresponding to the upper end of Figure 15, can be by the application of force and distending.
More specifically be, connector 10 is on its front, be that left-hand side has a slit 15 among Figure 16, extend with the axis direction of connector in slit 15, and have in the hole 16 that a screw forms in being embedded at the bottom of the connector, the screw embedded hole vertically extends and passes connector, and its upper end joins with slit 15.
And, in this embodiment, be formed on the lateral surface 12 of connector as the transition part 13 of recess, to constitute the structure of the resistance displacement between its adjacent lateral surface with other parts.
In this embodiment, though not show, connector is formed on the vertical section of its longitudinally to having the trapezoidal of inclination upside.
Screw 2a is embedded in the screw embedded hole 16, sees Figure 17 and Figure 18, and as screw 2a during by shallow embedding, as Figure 17, its pinnacle side does not reach slit 15, and therefore, the pinnacle side of wedge shape is not by distending.
On the other hand, when screw 2a is in depth embedded, its pinnacle side arrives 15 inside, slit, and the slit is by the application of force and distending, so the pinnacle of wedge shape is by distending.
Then, when connector 10 is connected on cross-connecting board 3 or the similarity piece, and screw 2a has just prevented that connector 10 from separating or displacement from cross-connecting board 3 or similarity piece when deeply being embedded in the screw embedded hole 16.According to this embodiment, between frame plate or similar item and cross-connecting board or similarity piece, be fixedly coupled by connector and can reach.And when removing screw 2a, just cross-connecting board 3 or similarity piece may be separated from frame plate 1 or similarity piece.
The connector 10 of present embodiment has the Embedded Division 14 that is formed on its front end face.Though Embedded Division forms column in the embodiment shown in fig. 10, and Embedded Division 14 in the present embodiment forms and has the cylindrical of oval part.The diameter parts that reduces of reach through hole 11 is opened eccentric position at Embedded Division.
Be formed with a hole on frame plate that connects the present embodiment connector or similar item one side, the shape in this hole and the form fit of embedded part are positioned at the position of corresponding embedded part, though do not have demonstration.
Do not resemble previous embodiment, reach through hole 11 forms to be eccentric in connector axis part.
When connector 10 is connected on frame plate 1 or the similar item with the screw 2 as fixture,, can prevent the rotation of connector self because the oval part and the embedded part of Embedded Division 14 are to be embedded in the hole these two.Connector fixedly is intelligible to stand on frame plate 1 or similar item.
In addition, in this embodiment, when connector 10 is set at the both sides of frame plate 1 and mutually centrally relatively the time, avoids mutually and therefore avoid both to play mutual collision as the screw of separately fixture.
