The present invention relates to a connecting tool or the like for connecting a target article such as a pipe material having a hollow portion to a mating article such as a plate material.

As a connecting structure for connecting a target article having a hollow portion to a mating article, it is a structure for connecting a pipe used for displaying products or the like to a plate-shaped bracket, and has a tubular shape with a sliding split at the shaft end of the pipe. By inserting the part, inserting the tapered nut from the opposite side of the bracket into the inside of the tubular part, and screwing the bolt from the bracket side toward the nut, the tubular part is expanded in the radial direction. A connecting structure is known in which a pipe is tightened from the inner peripheral side to connect the pipe and a bracket (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2002-31112

In the conventional connection structure, it is necessary to screw the bolt from the opposite side of the bracket while supporting the pipe on one side of the bracket. Therefore, the work is troublesome. If the worker cannot access or is difficult to access the opposite side of the bracket due to a large bracket or the like, the pipe cannot be connected.

Therefore, an object of the present invention is to provide a connecting tool or the like capable of neatly connecting an article to be connected to an article to be connected from one side.

The connecting tool according to one aspect of the present invention is a connecting tool for connecting a target article having a hollow portion that opens at least one end side to a mating article having a penetrating portion, and can be inserted into the hollow portion. A main body portion, an insertion portion arranged on one end side of the main body portion and capable of protruding from the hollow portion and passing through the penetrating portion, connecting the insertion portion and the main body portion, and from the insertion portion. A portion having a thin neck portion, from at least a part of the main body portion to the tip of the insertion portion via the neck portion, is a tightening portion constituting the main body portion and a hook portion constituting the insertion portion. The tightening portion is divided into a plurality of segments including the connecting portion constituting the neck portion, and the tightening portion is expanded from the basic state with a gap with respect to the inner surface of the hollow portion and the basic state. The hollow portion is provided so as to be displaceable from the working state of being in close contact with the inner surface, and the hooking portion can pass through the penetrating portion when the tightening portion is in the basic state, and the tightening portion can be passed through. The tightening portion is integrally displaceable so that the portion cannot pass through the penetrating portion when the portion is in the operating state, and the main body portion is provided with an operating member operated from the outside of the target article. An operation input unit is provided that displaces the tightening portion from the basic state to the operating state by contacting the operating member so as to transmit the operating force to the tightening portion of each segment.

The connecting structure according to one aspect of the present invention is a connecting structure in which a target article having a hollow portion that opens at least on one end side is connected to a partner article having a penetrating portion via the connecting tool of the above aspect. The main body of the connector is inserted into the hollow portion of the target article so that the insertion portion and the neck portion protrude toward one end side of the target article, and the insertion portion is the penetrating portion. It passes through the penetrating portion from one side and projects to the opposite side of the penetrating portion, and by operating the operating member, the tightening portion changes from the basic state to the working state, and the target article is moved to the target article. It is tightened from the inside of the hollow portion by the tightening portion, and the hooking portion meshes with the periphery of the penetrating portion to prevent the connecting tool from coming off from the mating article.

FIG. 1 shows an example of a connected structure according to one embodiment of the present invention. The illustrated connecting structure 1 connects a pipe 2 as an example of a target article and a panel 3 as an example of a mating article to each other via a connecting tool 4 inserted in the pipe 2. The connector 4 can be operated from the outside of the pipe 2 by the bolt 5 as an example of the operating member. With the operation of the bolt 5, the pipe 2 can be connected to or removed from the panel 3 only by operating on one side of the panel 3. The pipe 2 is, for example, a hanger pipe for suspending and supporting goods, decorations and various other articles. However, the target article can be appropriately changed as long as there is a hollow portion into which the connector 4 can be inserted on one end side thereof. Although the panel 3 is drawn in a disk shape in FIG. 1, the shape and size of the panel 3 may be appropriately set.

2 to 6 show the details of the connector 4. In the following, the X-axis direction of FIG. 2 is the front-rear direction of the connector 4, the Z-axis direction of FIG. 2 is the vertical direction of the connector 4, and the Y direction orthogonal to the paper surface of FIG. 2 is the left and right of the connector 4. The left side in the X-axis direction may be referred to as the front end side of the connector 4, and the opposite side may be referred to as the rear end side. However, these directions are defined for convenience of explanation, and do not mean the front-back, left-right, and up-down relationships when the connector 4 is used.

As is clear from FIGS. 2 and 5, the connector 4 is configured as an assembled part in which a pair of

segments

10 and 20 are combined. The

segments

10 and 20 are configured as separate parts that can be separated from each other. In the following, the upper segment 10 in FIG. 2 will be referred to as a first segment and the lower segment 20 will be referred to as a second segment to distinguish them, and if it is not necessary to distinguish between them, they will be referred to as

segments

10 and 20. Sometimes. However, the terms "first" and "second" are used to distinguish the

segments

10 and 20, and are not intended for other concepts such as master-slave relationship and predecessor relationship.

FIGS. 2 to 4 show a basic state in which

segments

10 and 20 are combined so as to be in close contact with each other. In the basic state, the connector 4 connects the main body 41 that can be inserted into the pipe 2, the insertion portion 42 that is coaxially arranged on the tip side of the main body 41, and the main body 41 and the insertion portion 42. It has a neck 43. The main body 41 is configured as a shaft-shaped portion that can be inserted into the pipe 2. The outer peripheral surface of the main body 41 has a tapered surface shape that gradually narrows toward the tip end side. The outer diameter of the main body 41 is set to such an extent that some gap is generated with respect to the inner peripheral surface of the pipe 2 in the basic state.

The insertion portion 42 is configured as a short shaft-shaped portion having a size capable of passing through the through hole 3a (FIG. 7) provided in the panel 3. The outer diameter of the insertion portion 42 will be described later. The neck portion 43 is coaxial with the main body portion 41 and the insertion portion 42, and has a smaller diameter than the insertion portion 42. A tapered surface 44 that gradually narrows toward the rear end side of the connector 4 is formed at the connecting portion between the insertion portion 42 and the neck portion 43 (see also FIGS. 9 and 10). Although the through hole 3a is formed in a circular shape as an example, the through hole 3a may be formed in a polygonal shape such as a quadrangular shape. The outer periphery of the tip of the main body 41 and the insertion portion 42 may be chamfered to an appropriate size.

The

segments

10 and 20 basically have a shape in which the connector 4 is divided into two along the axis AX in the range from the main body portion 41 to the tip of the insertion portion 42 via the neck portion 43. As a result, the first segment 10 is provided with a tightening portion 11, a hooking portion 12, and a connecting portion 13 that form substantially half of each of the main body portion 41, the insertion portion 42, and the neck portion 43. However, the rear end side of the first segment 10 is provided with a support portion 14 that constitutes the entire circumference of the rear end side of the connector 4. A groove portion 15 penetrating the first segment 10 in the left-right direction is provided on the tip end side of the support portion 14. The inner peripheral surface of the groove portion 15 is curved so as to draw a cylindrical surface, one end portion along the bending direction intersects the front surface 14a of the support portion 14, and the other end portion intersects the stopper surface 15a. The stopper surface 15a intersects the mating surface 16 with respect to the second segment 20. The mating surface 16 extends from the tightening portion 11 through the connecting portion 13 to the tip of the hooking portion 12. The mating surface 16 is provided so as to form a plane parallel to the axis AX of the connector 4.

On the other hand, the second segment 20 is provided with a tightening portion 21, a hooking portion 22, and a connecting portion 23 that form the remaining half circumference of each of the main body portion 41, the insertion portion 42, and the neck portion 43. On the rear end side of the second segment 20, a shaft portion 25 that can be inserted into the groove portion 15 of the first segment 10 is provided so that its axis direction is orthogonal to the axis AX of the connector 4. The shaft portion 25 is provided with a stopper surface 25a that faces the stopper surface 15a when inserted into the groove portion 15. The mating surface 16 extends from the tightening portion 11 through the connecting portion 13 to the tip of the hooking portion 12. The stopper surface 25a intersects the mating surface 26 with respect to the first segment 10. The mating surface 26 extends from the tightening portion 21 through the connecting portion 23 to the tip of the hooking portion 22. The mating surface 26 is provided so as to form a plane parallel to the axis AX of the connector 4. Further, at the connection position between the tightening portion 21 and the shaft portion 25, a relief portion 27 that creates a gap between the tightening portion 21 and the front surface 14a of the support portion 14 of the first segment 10 is provided.

As is clear from FIG. 5, the

segments

10 and 20 are combined with each other by inserting the shaft portion 25 of the second segment 20 into the groove portion 15 of the first segment 10 from the side. In the combined state, the basic state in which the mating surfaces 16 and 26 of the

segments

10 and 20 are in close contact with each other as shown in FIGS. 2 to 4 and the shaft portion 25 in the groove portion 15 as shown in FIG. It is possible to rotate the connector 4 so that the mating surfaces 16 and 26 are separated from each other as shown by the arrow A.

Returning to FIGS. 2 to 4, a planar notch surface 28 parallel to the axis AX is provided on the outer circumference of the second segment 20. Further, the second segment 20 is provided with a screw hole 29 penetrating the tightening portion 21 from the cutout surface 28 to the mating surface 26. The screw hole 29 is for screwing the bolt 5, and its axis is orthogonal to the mating surface 26 as an example. The cutout surface 28 makes it possible to facilitate the processing of the screw hole 29, but the cutout surface 28 may be omitted if it is not necessary.

Next, the usage of the connector 4 will be described with reference to FIGS. 7 and 8. When the connector 4 is used, it is necessary to provide a punch hole 2a for passing the bolt 5 on the outer circumference of the pipe 2 and a through hole 3a for passing the insertion portion 42 on the panel 3 in advance. .. The through hole 3a is an example of a through portion. Instead of the through hole 3a, a groove penetrating the panel 3 may be provided as a through portion.

In order to connect the pipe 2 to the panel 3, first, as shown in FIG. 7, the main body 41 of the connecting tool 4 is inserted into the inner circumference on one end side of the pipe 2, and the bolt 5 is inserted from the extraction hole 2a. The bolt 5 is screwed into the screw hole 29 of the second segment 20. However, the bolt 5 may be screwed in within a range in which the connector 4 can maintain the above-mentioned basic state. From this state, the insertion portion 42 is passed through the through hole 3a from one side (hereinafter, front side) of the panel 3, and the entire insertion portion 42 is projected to the opposite side (hereinafter, back side) of the panel 3. After that, as shown in FIG. 8, the bolt 5 is screwed in to push in the first segment 10. The pushing force (operating force of the bolt 5) at this time is transmitted to the first segment 10 via the mating surface 16, and the reaction force generated on the mating surface 16 is transmitted to the second segment 20 through the screw hole 29. NS. As a result, the

segments

10 and 20 rotate relative to the shaft portion 25. By screwing the bolt 5 until the tightening

portions

11 and 21 tighten the pipe 2 from the inside, the pipe 2 can be restrained so as not to be pulled out from the connector 4. The state of FIG. 8 corresponds to the working state of the tightening

portions

11 and 21. Further, the mating surface 16 of the screw hole 29 and the first segment 10 acts on the tightening

portions

11 and 21 from the basic state by contacting the bolt 5 so as to transmit the operating force of the bolt 5 to the tightening

portions

11 and 21. It functions as an example of an operation input unit that displaces to a state.

On the other hand, by tightening the bolt 5, the hooking

portions

12 and 22 and the connecting

portions

13 and 23 also rotate integrally with the tightening

portions

11 and 21. Therefore, on the back side of the panel 3, each of the hooking

portions

12 and 22 is displaced outward in the radial direction, and the insertion portion 42 expands. At this time, the outer diameter of the insertion portion 42 becomes larger than the through hole 3a so that the insertion portion 42 cannot pass through the through hole 3a, and the insertion portion 42 is smaller than the through hole 3a in the basic state of FIGS. The outer diameter of the insertion portion 42 is set so that it can pass through the through hole 3a. Further, the neck portion 43 is formed to be sufficiently thin so as not to interfere with the edge of the through hole 3a. Therefore, in the operating state of FIG. 8, the hooking

portions

12 and 22 mesh with each other around the through hole 3a, and the connector 4 cannot be pulled out from the through hole 3a. As a result, the pipe 2 and the panel 3 are connected to each other.

9 and 10 show an example of the relationship between the tapered surface 44 of the connector 4 and the through hole 3a of the panel 3. As shown in FIG. 9, when the insertion portion 42 of the connector 4 is passed through the through hole 3a, the tapered surface 44 is at a position retracted toward the axis AX side from the edge of the through hole 3a. On the other hand, when the

segments

10 and 20 are opened and the tightening

portions

11 and 21 are deformed into the working state, the tapered surface 44 comes into contact with the edge of the through hole 3a, and as the

segments

10 and 20 are further rotated, the connector 4 The whole is pulled toward the tip side in the front-rear direction as shown by the arrow F. Therefore, the pipe 2 can be pressed against the panel 3 to improve the stability of the pipe 2.

The material of the connecting tool 4 may be appropriately selected according to the configuration, material, etc. of the pipe 2 as the target article and the panel 3 as the mating article. For example, the connector 4 may be composed of a metal material such as iron, stainless steel, aluminum steel, or brass, or the connector 4 may be composed of a non-metal material such as resin. The material of the connecting tool 4 can be appropriately selected according to the rigidity and strength required for the connecting tool 4.

As is clear from the above description, according to the connector 4 of the present embodiment, the pipe 2 can be neatly connected to the panel 3 only by the work on the front side of the panel 3. Since it is not necessary to insert bolts from the back side of the panel 3, the pipe 2 can be connected even in an environment where the work on the back side of the panel 3 is difficult or impossible. Therefore, even when the panel 3 is arranged on the wall surface, ceiling surface, floor surface, or the like of a structure such as a building, there is a gap on the back side of the panel 3 into which the insertion portion 42 can be inserted. As long as the pipe 2 can be connected.

The present invention is not limited to the above-mentioned form, and may be carried out in a form in which appropriate modifications or changes are made. For example, in the above embodiment, the segments do not necessarily have to be configured as separate parts that can be separated from each other. The segment may be provided in an appropriate manner as long as the range from at least a part of the main body of the connector to the tip of the insertion portion through the neck is divided into a tightening portion, a connecting portion and a hooking portion. For example, as shown in FIG. 11, a through hole 30 is formed on the rear end side of the main body 41, and a handrail is formed from the through hole 30 toward the tip of the insertion portion 42, thereby forming the first segment 10A and the first segment 10A. The second segment 20A may be formed. Even in this case, the

segments

10A and 20A can be displaced by operating the bolt 5 as in FIGS. 7 and 8.

The segment does not necessarily have to be provided so as to be relatively rotatable at an appropriate place in the main body. For example, as shown in FIG. 12, the first segment 10B and the second segment 20B may be provided so as to be relatively displaced in parallel in the vertical direction (arrow B direction) along the slide portion 31. Even in this case, it is possible to hook the hooking

portions

13 and 23 to the back surface side of the through hole 3a to prevent the connecting tool 4 from coming off while tightening the pipe 2 from the inner surface side at the tightening

portions

11 and 21.

The operating member that displaces the

segments

10 and 20 is not limited to the bolt 5, and various members such as a set screw (enamel set), a split pin, and a wedge may be used as the operating member. The operation input unit may be appropriately deformed according to the configuration of the operation member. A wedge member is interposed between the mating surfaces 16 and 26 of the

segments

10 and 20, and the wedge member is operated in the front-rear direction by an operating member such as a pin inserted from the outside of the pipe 2 to displace the

segments

10 and 20. It is also possible. When pins and wedges are used as operating members, they may be appropriately prevented from coming off. However, when the wedge is used as the operating member, the operating member may be prevented from coming off by utilizing the automatic stopping action of the wedge. The number of segments is not limited to two, and may be three or more as appropriate. That is, the connector may be divided into three or more segments.

In the above embodiment, an example of connecting the pipe 2 to the panel 3 has been described, but as long as the target article has a hollow portion that opens at one end side and allows the connector to be inserted, an appropriate article is regarded as the target article. good. For example, even for a solid article such as a leg of a table, the connector of the present invention can be applied by providing a hollow portion on one end side thereof. The target article does not necessarily have to be cylindrical or cylindrical. The present invention can be applied even to an article having a polygonal cross section by adapting the outer peripheral shape of the connector to the inner peripheral shape of the hollow portion. The mating article is not limited to the plate-shaped panel 3, and an appropriate article may be selected as the mating article as long as it has a penetrating portion to which the insertion portion is inserted and the hooking portion of each segment is engaged. For example, when the wall surface of the building itself is provided with a penetrating portion, the wall surface may be used as a mating article. That is, the counterpart article is not limited to the parts having portability, and the structure fixed to the structure or the like is also included in the category. Further, the mating part may be an assembly in which a part such as a plate having a penetrating portion is combined with another structure. For example, by providing a recess on the back surface side of the top plate of the table and providing a penetrating portion on the plate attached to the top plate so as to cover the recess, the connector of the present invention is attached to the upper end of the leg portion. , The connecting tool of the present invention can be applied to the connecting portion between the top plate and the recess. Further, the connector of the present invention may also be used as a basis for attaching or supporting additional parts different from the target article. For example, in the examples of FIGS. 2 to 4, the support portion 14 may be used as a basis for further attaching parts different from the pipe 2 and the panel 3. As an example, a female screw portion may be formed on the end surface of the support portion 14, and additional parts may be screwed to the female screw portion.

The penetrating portion is not limited to the through hole, and an appropriate penetrating shape may be used as the penetrating portion as long as the insertion portion can be projected to the opposite side and hooked. The penetrating portion does not necessarily have to penetrate to the back surface side of the mating article. For example, as shown in FIG. 13, when the wall member 3A formed by connecting the expansion grooves 3c to the tip of the through groove 3b is used as the mating article, the insertion portion 42 of the connecting tool 4 is passed through the through groove 3b. The pipe 2 can be connected to the wall member 3A as in the example of FIG. 8 by advancing to the expansion groove 3c and then displacing the tightening

portions

11 and 21 to the working state. In the example of FIG. 13, the through groove 3b and the expansion groove 3c may be formed in different parts, and these parts may be combined to form a mating part such as a wall member 3A.

Various aspects of the present invention derived from each of the above-described embodiments and modifications are described below. In the following description, in order to facilitate understanding of each aspect of the present invention, the corresponding components shown in the accompanying drawings are added in parentheses, thereby limiting the present invention to the illustrated form. It's not something.

In the connector (4) according to one aspect of the present invention, the target article (2) having a hollow portion that opens at least on one end side is transformed into a mating article (3; 3A) having a penetrating portion (3a; 3b). A connecting tool for connecting, a main body portion (41) that can be inserted into the hollow portion, and an insertion portion that is arranged on one end side of the main body portion and can protrude from the hollow portion and pass through the penetrating portion. (42) has a neck portion (43) that connects the insertion portion and the main body portion and is thinner than the insertion portion, and the tip of the insertion portion passes through the neck portion from at least a part of the main body portion. The portions leading to are the tightening portions (11, 21) constituting the main body portion, the hooking portions (12, 22) constituting the insertion portion, and the connecting portions (13, 23) constituting the neck portion. It is divided into a plurality of segments (10, 20; 10A, 20A; 10B, 20B) including the above, and the tightening portion is in a basic state with a gap with respect to the inner surface of the hollow portion (as an example, the state of FIG. 7). ) And the working state (as an example, the state of FIG. 8) that expands from the basic state and comes into close contact with the inner surface of the hollow portion, and the hooking portion is the tightening portion. Is displaceable integrally with the tightening portion so that it can pass through the penetrating portion when it is in the basic state and cannot pass through the penetrating portion when the tightening portion is in the working state. The tightening portion is brought into contact with the main body portion so as to transmit the operating force of the operating member (5) operated from the outside of the target article to the tightening portion of each segment. The operation input units (16, 29) for displacing from the basic state to the working state are provided.

In the connecting structure (1) according to one aspect of the present invention, the target article (2) having a hollow portion that opens at least on one end side is transformed into a mating article (3; 3A) having a penetrating portion (3a; 3b). On the other hand, it is a connecting structure that connects via the connecting tool (4) of the above aspect, and the connecting portion (42) and the neck portion (43) are projected from the one end side of the target article. The main body portion (41) of the tool is inserted into the hollow portion of the target article, and the insertion portion passes through the penetrating portion from one side of the penetrating portion and projects to the opposite side of the penetrating portion. By the operation of the operating member (5), the tightening portions (11, 21) are changed from the basic state to the working state, and the target article is tightened from the inside of the hollow portion by the tightening portion. The hooking portions (12, 22) are engaged with the periphery of the penetrating portion to prevent the connecting tool from coming off from the mating article.

According to the above aspect, the main body of the connector is inserted into the hollow portion of the target article while the tightening portion is maintained in the basic state, and the insertion portion is inserted into one side of the mating article, that is, the side to which the target article is connected. By inserting it into the penetrating part and projecting it to the opposite side, and then operating the operating member to displace the tightening part in the working state, the target article is tightened from the inside of the hollow part at the tightening part. , The hooking portion can be engaged around the penetrating portion to prevent the connector from coming off from the mating article. As a result, the target article is connected to the other article via the connector. Since the target article can be connected to the other article only by the work on one side of the other article, the work can be performed efficiently. Since it is not necessary to work on the opposite side of the mating article, it is possible to connect the target articles even in an environment where it is difficult or impossible to work on the opposite side of the mating part.

In the above aspect, a tapered surface (44) that gradually becomes thinner toward the main body may be provided at the connection position between the insertion portion and the neck portion. According to this, the edge of the penetrating portion comes into contact with the tapered surface with the outward displacement of the hooking portion, whereby the action of pulling the connecting tool to the opposite side of the mating article occurs. Therefore, it is possible to improve the stability of the target article by pressing it against the mating part.

Further, each of the plurality of segments may be configured as a separate component that can be separated from each other. According to this, it is possible to displace the segments relatively freely with each other as compared with the case where a part of the segments is integrated. Therefore, it is convenient to give the displacement required for connection to the tightening portion and the hooking portion.
