Description
Technical Field
The present invention relates to the field of connector technology, and more particularly, to a connector for connecting a plurality of objects.
Background
It is known to connect a plurality of panels in a freely combined manner to construct various types of sectional furniture. For example, when the shelf is assembled as a sectional furniture, a shelf body is formed by a top plate, a bottom plate, and left and right side plates, a back plate is mounted on the shelf body, and a plurality of shelf plates are further mounted on the inner side of the shelf body. As a method for connecting such a plurality of members, a connector composed of a screw and a nut is generally known. Such a connector can stably fix a member to be connected, but a procedure of screwing a screw with a tool is required.
It is known to connect a plurality of panels in a freely combined manner to construct various types of sectional furniture. For example, when the shelf is assembled as a sectional furniture, a shelf body is formed by a top plate, a bottom plate, and left and right side plates, a back plate is mounted on the shelf body, and a plurality of shelf plates are further mounted on the inner side of the shelf body. As a method for connecting such a plurality of members, a connector composed of a screw and a nut is generally known. Such a connector can stably fix a member to be connected, but a procedure of screwing a screw with a tool is required.
However, in the case of using the connector, since the annular projection is formed around the entire circumference in the circumferential direction, insertion resistance when the insertion pin is inserted into the insertion hole of the mating member is relatively large. Therefore, depending on the material of the target member, a large load may be imposed on the insertion operation.
Disclosure of Invention
An object of the present invention is to solve the above-described problems and to provide a connector capable of fixing objects to each other in a stable connected state while improving workability in connecting a plurality of objects.
In order to achieve the purpose, the invention adopts the following technical scheme: a connector comprises a body in a column state and a fixing part, and is characterized in that the fixing part comprises a plurality of bulges, the bulges are arranged on the peripheral surface of the body in a mutually separated mode, and the peripheral surface takes the shaft of the body as an axis.
Preferably, the protrusions are provided apart from each other along a circumferential direction of the outer circumferential surface.
Preferably, the protrusions are provided at equal intervals along a circumferential direction of the outer circumferential surface.
Preferably, the projections adjacent to each other in the circumferential direction of the outer circumferential surface are provided so as to be offset from each other in the axial direction of the body.
Preferably, the projections adjacent to each other in the circumferential direction of the outer circumferential surface are arranged to be staggered with each other in the axial direction of the body.
Preferably, the projections are provided at the same positions in the circumferential direction of the outer circumferential surface, with the projections facing each other about the axis of the body.
Preferably, the protrusions are provided on the outer circumferential surface so as to be spaced apart from each other in an axial direction of the body.
Preferably, the projection is in a flat plate state.
Preferably, a tip end of the projection is inclined toward one end side in the axial direction of the body.
Preferably, the flange is connected to one end of the body in the axial direction and includes a protruding portion protruding outward in the radial direction around the axis of the body and exceeding the outer circumferential surface of the body.
Preferably, the guide portion is connected to the other end of the body, and a cross section of the guide portion along the axis of the body has a substantially pedestal state that is tapered from the bottom end toward the front end.
A second aspect of the present invention provides a connector including the connector according to any one of the above aspects.
The invention has the beneficial effects that:
1. since the protrusions are spaced apart from each other in the circumferential direction of the outer circumferential surface of the body, the contact stress per unit area generated at the contact portion of the protrusions with the inner surface of the insertion hole of the object is greater than that generated at the contact portion of the protrusions with the inner surface of the insertion hole of the object in the circumferential direction, so that the fixing force of the body in the object is increased and the body is stably fixed in the object.
2. The projection is in a flat state, and can generate higher contact stress, so that the body can be fixed in the object more stably.
3. Since the protrusions are provided in the circumferential direction of the outer circumferential surface of the body so as to be spaced apart from each other, the insertion resistance of the body is reduced as compared with a structure in which the protrusions are formed in the entire circumferential direction, and workability in attaching the connector to an object can be improved.
4. Since the guide portion and the protrusion are inserted while pressing and expanding the diameter of the insertion hole, the diameter of the insertion hole is smaller than that of a substantially circular imaginary circle formed by connecting the protrusions, and therefore, the diameter of the insertion hole does not require high dimensional accuracy, and the diameter can be set relatively freely.
5. By the projections being provided so as to be adjacent to each other in the circumferential direction of the outer peripheral surface of the body so as to be offset from each other in the axial direction of the body, the contact area of the projections with the insertion holes is formed in the axial direction in a wide range with little interruption, and the connector can achieve a more stable connection state than a configuration in which the projections are provided at substantially the same positions in the circumferential direction as each other.
6. Since the protrusions are provided at substantially the same positions in the circumferential direction as the protrusions provided in the opposing direction with respect to the axis of the body, the abutting portions between the protrusions and the inner surface of the insertion hole are formed symmetrically with respect to the insertion axis. Therefore, stress generated by the abutting portion of the protrusion and the inner surface of the insertion hole is not biased in the circumferential direction, and the connector can achieve a more stable connection state.
7. Since the protrusion is provided such that the tip of the protrusion is inclined toward the flange on the side of the one end portion in the axial direction of the body, insertion resistance generated when the body is inserted into an insertion hole of an object to be described later can be reduced as compared with a non-inclined state, and the tip of the protrusion generates contact stress in the direction opposite to the direction in which the body is pulled out, and the body can be prevented from being pulled out from the insertion hole.
8. The flange is arranged at one end of the body, the flange comprises the extension part, the body can be prevented from being excessively inserted into the insertion hole, the extension part of the flange is abutted against the outer surface of the second object, and the connection part of the objects can be stably fixed through the combination of the fixing structure generated between the body and the first object.
With the structural design of the present invention, the connector can improve workability in connecting objects and can fix the objects to each other in a stable connected state.

Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative only and not to limit the scope of the invention; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Please refer to FIGS. 1-5
As shown in fig. 1 to 3, the connector 1 includes a body 10, a fixing portion 20, a flange 30, and a guide portion 40.
The connector 1 is made of resin, metal, rubber or other materials.
The main body 10 constitutes a trunk portion of the connector 1 and is a portion to be inserted into the insertion holes 100a and 200a, and the main body 10 is in a substantially elliptical cylindrical state having a linear portion in cross section, and has an outer diameter around an cylindrical axis (hereinafter also referred to as "axis") L smaller than an inner diameter of the insertion holes 100a and 200 a.
The fixing portion 20 is disposed on an outer peripheral surface of one end side of the body 10 in the axial direction, the fixing portion 20 includes a plurality of protrusions 21, the protrusions 21 are disposed on the outer peripheral surface of the body 10 separately from each other, and the outer peripheral surface takes the axis L of the body 10 as an axis. The fixing portion 20 abuts against the inner surfaces of the insertion holes 100a and 200a when the body 10 is positioned in the insertion holes 100a and 200 a. The fixing portion 20 functions to fix the body 10 in the insertion holes 100a and 200a by the contact stress generated by the contact.
The protrusions 21 are provided at approximately quarter circumferential positions along the circumferential direction of the outer circumferential surface, and a plurality of protrusions 21 are provided at approximately equal intervals along the axis L of the body 10. Hereinafter, the plurality of projections formed along the axis L at the circumferential direction positions will be also described as the projections 21a in the first row, the projections 21b in the second row, the projections 21c in the third row, and the projections 21d in the fourth row.
Wherein the projection 21 is formed in a flat plate state. The projection 21 has paired facing surfaces 21e, 21f and a side peripheral surface 21 g; the paired facing surfaces 21e, 21f are surfaces facing the extending side of the axis L and extending in parallel to each other; the facing surface 21e faces the flange 30, and the facing surface 21f faces the guide portion 40; the side circumferential surface 21g extends between the paired facing surfaces 21e, 21 f.
Wherein the projections 21 adjacent to each other in the circumferential direction of the outer circumferential surface of the projections 21 are disposed to be offset from each other along the axis L of the body 10. For example, the projections 21b of the second row adjacent to the projections 21a of the first row are provided at the positions of the gaps between the projections 21a of the first row in the circumferential direction. The other projections 21 adjacent in the circumferential direction are also arranged in the same positional relationship with each other. That is, the projections 21 formed so as to be adjacent in the circumferential direction are arranged to be offset from each other in the direction of the axis L of the body 10.
Wherein the projections 21 are provided at substantially the same positions in the circumferential direction of the outer circumferential surface, with the projections 21 facing each other about the axis L of the body 10. For example, the first row of projections 21a and the third row of projections 21c opposed thereto are provided at substantially the same positions in the circumferential direction of the outer peripheral surface. In order to realize this structure, it is preferable that an even number of projections 21 ( projection rows 21a, 21b, 21c, 21d) are formed in the circumferential direction of the outer circumferential surface.
Wherein the protrusion 21 is provided to be inclined from a bottom end to a front end toward one side of the flange 30 along an axial direction of the body 10. In other words, the projection 21 extends outward from the outer peripheral surface of the body 10 in a direction away from the leading end guide 40. The inclination angle of the projections 21 is set to be substantially equal to each of the projections 21a, 21b, 21c, 21d in each row.
The flange 30 is connected to one end side of the body 10 in the axial direction. The flange 30 has an effect of preventing the body 10 from being excessively inserted into the insertion holes 100a and 200a and functioning as a stopper.
Wherein the flange 30 has a slightly circular plate state. The flange 30 includes a protruding portion 30a, and the protruding portion 30a protrudes outward in the diameter direction about the axis L beyond the outer peripheral surface of the body 10. The outer diameter of the extension 30a is larger than the inner diameter of the insertion holes 100a and 200 a. The outer side surface of the flange 30 has a curved surface in a convex state.
Wherein the guide portion 40 is connected to the other end of the body 10. The guide portion 40 has a function of guiding the insertion of the body 10 into the insertion holes 100a and 200a smoothly.
The guide portion 40 has a substantially flat shape tapering from the bottom end toward the front end in a cross section along the axis L. When the connector 1 is viewed from the bottom end in the direction of the axis L, the protrusions 21a, 21c of the guide portion 40 extend in the same direction in the opposite direction with respect to the axis L of the body 10, that is, the extension lines of the protrusions 21b, 21d are staggered with respect to the opposite direction with respect to the axis L of the body 10. The guide 40 includes a bottom end face 41, a pair of main faces 42, and a pair of side faces 43. The bottom end surface 41 is a surface of the bottom end connected to the body 10 and faces the flange 30. Both ends of the bottom end surface 41 extend beyond the body 10. The pair of main surfaces 42 are arranged in parallel with each other at a predetermined interval. Each main surface 42 is a surface perpendicular to the base end surface 41 and faces a direction in which each of the projections 21b and 21d extends. The main surface 42 has a substantially flat state. The side surface 43 is a surface perpendicular to the pair of main surfaces 42. The pair of side surfaces 43 extend so as to approach each other from the bottom end surface 41 toward the front end, meeting at the front end of the guide portion 40. The front end of the guide 40 is formed with a curvature.
The width of the bottom end of the guiding portion 40 is larger than the outer diameter of the body 10, and is formed to be the same as, slightly the same as or slightly larger than the inner diameter of the insertion holes 100a and 200 a. The width of the bottom end of the guide 40 is smaller than the width between the protrusions 21a and 21c in the opposing direction around the axis L of the main body 10.
As shown in fig. 4 to 5, two objects are connected by the connector 1. The following description relates to an example of assembling an L-shaped connection body by connecting a first object 100 and a second object 200 formed in a plate state. The first object 100 and the second object 200 are made of, for example, wood. The objects 100 and 200 can be made of various materials, not limited to wood.
As shown in fig. 4(a), the first object 100 and the second object are respectively provided with insertion holes 100a and 200a through which the connector 1 is inserted. The first object 100 has two insertion holes 100a extending in a direction substantially perpendicular to the thickness direction thereof. The second object 200 has two insertion holes 200a extending in a direction approximately parallel to the thickness direction thereof. The insertion holes 100a and 200a of the first object 100 and the second object 200 are arranged coaxially in a state where the objects 100 and 200 are arranged in an L shape.
As shown in fig. 4(a) and (b), the connector 1 is mounted in the insertion holes 100a and 200a in a state where the first object 100 and the second object 200 are arranged in an L shape and the insertion holes 100a and 200a are arranged coaxially. Specifically, the connector 1 is mounted in the insertion holes 100a and 200a in a state where the body 10 of the connector 1 is inserted into the insertion holes 100a and 200a and the extension portion 30a of the flange 30 abuts against the outer surface of the second object 200.
The connector 1 is mounted by the pressing flange 30 with the guide 40 as the tip and with the shafts of the main body 10 disposed in the insertion holes 100a and 200a being substantially parallel to each other. The method of pressing the flange 30 may be a method of pressing the flange 30 with the hand of an operator, or a method of striking the flange 30 with a tool such as a mallet. Various pressing methods can be used according to the magnitude of insertion resistance generated between the protrusion 21 and the inner surface of the insertion hole 100a, 200a when the body 10 is inserted into the insertion hole 100a, 200 a.
As shown in fig. 5(a), the connector 1 is brought close to the first object 100 and the second object 200 from the front end side where the guide portion 40 is provided. In the case of using the connector 1 of the present embodiment, the diameter of the insertion holes 100a, 200a is preferably smaller than the diameter of an imaginary circle in a slightly circular state formed by connecting the projections 21a to 21d to each other.
When the diameter of the insertion holes 100a, 200a is smaller than the width of the bottom end of the guide 40, the connector 1 is inserted into the insertion holes 100a, 200a while the guide 40 is in contact with the inner surfaces of the insertion holes 100a, 200 a. Thereby, the diameter of the insertion holes 100a, 200a at the position in contact with the guide portion 40 is enlarged, and the insertion of the subsequent projection 21 into the insertion holes 100a, 200a becomes easy. The connector 1 is inserted into the insertion holes 100a and 200a by pushing the material of the insertion holes 100a and 200a of the first and second objects 100 and 200 outward in the diameter direction while contacting the inner surfaces of the insertion holes 100a and 200a with one side of the facing surface 21f of the projection 21.
As shown in fig. 5(b), in a state where the connector 1 is inserted into the insertion holes 100a, 200a, the front end portion of the projection 21 is pressed into the inner surface of the insertion hole 100a of the first object, whereby the body 10 is fixed to the first object. In this state, the extension portion 30a of the flange 30 abuts against the outer surface of the second object. That is, one side of the connection portion between the first object 100 and the second object 200 is fixed by the fixing of the body 10 and the first object, and the other side of the connection portion is fixed by the abutment between the flange 30 and the second object.
According to such a configuration, both side portions of the connection portion of the first object 100 and the second object 200 are fixed, and thus the first object 100 and the second object 200 are fixed in a stable connection state as an L-shaped connection body.
As described above, with the connector 1 of the above embodiment, the objects 100 and 200 can be connected to each other only by being attached to the insertion holes 100a and 200a of the objects 100 and 200 without using an additional connecting member.
In the connector 1 of the above embodiment, the projections 21 are provided separately from each other in the circumferential direction of the outer circumferential surface of the body 10. Therefore, the contact stress per unit area generated at the contact portion of the protrusion 21 with the inner surface of the insertion hole 100a of the object 100 is larger than that of the structure in which the protrusion is provided in the entire circumferential direction. Thereby, the fixing force of the body 10 in the object 100 is increased, and the body 10 is stably fixed in the object 100. In particular, since the projection 21 is in a flat plate shape, a higher contact stress can be generated, and thus the main body 10 is more stably fixed in the object 100.
In the connector 1 of the above embodiment, the projections 21 are provided separately from each other in the circumferential direction of the outer circumferential surface of the body 10. Therefore, compared to a structure in which the protrusions are formed in the entire circumferential direction, the insertion resistance of the body 10 is reduced. This can improve workability in attaching the connector 1 to the objects 100 and 200.
In the connector 1 of the above-described embodiment, since the guide portion 40 and the protrusion 21 are inserted while pressing and expanding the diameters of the insertion holes 100a and 200a, the insertion holes 100a and 200a may be smaller than the diameter of a virtual circle of a substantially circular shape formed by connecting the protrusions 21a to 21d to each other. Therefore, the diameters of the insertion holes 100a and 200a do not need to be highly precise, and the diameter can be set relatively freely.
With the connector 1 of the above embodiment, the projections 21 that are the projections 21 provided adjacent in the circumferential direction of the outer circumferential surface of the body 10 are provided offset from each other in the direction of the axis L of the body 10. Therefore, almost all regions of the fixing portion 20 in the axial direction of the body 10, any one of the protrusions 21a, 21b, 21c, 21d of each row is in contact with the inner surface of the insertion hole 100a of the object 100, that is, the contact region of the protrusion 21 with the insertion hole 100a is formed widely in the axial direction with almost no interruption. Thereby, the connector 1 can achieve a more stable connection state than, for example, a configuration in which the adjacent projections 21 are provided so as not to be offset from each other (a configuration in which the projections are provided at substantially the same positions in the circumferential direction).
With the connector 1 of the above-described embodiment, the projections 21 are provided at substantially the same positions in the circumferential direction as the projections 21 in the opposing direction centered on the axis L of the body 10. Therefore, the contact portion between the boss 21 and the inner surface of the insertion hole 100a is formed symmetrically about the insertion axis L. Therefore, stress generated by the abutting portion between the protrusion 21 and the inner surface of the insertion hole 100a is not biased in the circumferential direction, and the connector 1 can achieve a more stable connection state.
With the connector 1 of the above-described embodiment, the projection 21 is provided such that the front end of the projection 21 is inclined toward the flange 30 side on the side of the one end portion in the axial direction of the body 10. With this, compared to the non-inclined state, insertion resistance generated when the main body 10 is inserted into an insertion hole of an object to be described later can be reduced. Further, since the contact portion between the boss 21 and the inner surface of the insertion hole generates a contact stress in the opposite direction to the direction of pulling out the body 10 at the tip of the boss 21 due to the inclined arrangement of the boss 21, the body 10 can be prevented from being pulled out from the insertion hole.
With the connector 1 of the above embodiment, since the flange 30 is included at one end of the body 10, and the flange 30 includes the protruding portion 30a, the body 10 can be prevented from being excessively inserted into the insertion holes 100a and 200 a. Further, since the extension 30a of the flange 30 abuts against the outer surface of the second object 200, the connection portion of the objects 100 and 200 can be stably fixed by the combination of the fixing structure generated between the main body 10 and the first object 100.
Example 2
As shown in fig. 6(a), the connector provided by the embodiment of the second aspect of the present invention includes a connector.
