Description

  The present invention relates to a handle connecting structure, and in particular, by inserting one rod member into the hollow interior of the other rod member and locking the rod member while maintaining a predetermined overlap length, The present invention relates to a handle connecting structure that forms a handle in which members are connected and integrated in the axial direction.

  For example, a handle such as a handle of a cleaning tool or a handle of a cane may be formed by connecting and integrating a plurality of rod members having a compact length so as to be detachable in the axial direction. As a structure for connecting and integrating a plurality of rod members so as to be detachable in the axial direction, for example, one of a pair of adjacent rod members is inserted into the hollow interior of the other rod member, and a predetermined overlap length is obtained. A connection structure is known in which the bending stress applied to the connection portion can be stably supported at the overlapping portion by being locked in a state where the thickness is held (see, for example, Patent Document 1). Further, in such a connection structure, a plurality of locking holes are preferably formed in the circumferential surface of the other rod member having a hollow interior at intervals in the length direction, and selected from these locking holes. It is possible to change the length of the handle by changing the locking hole for locking the locking projection provided on one rod member (see, for example, Patent Document 2).

  On the other hand, in the connection structure of Patent Document 1 and Patent Document 2, as a locking member for locking one rod member and the other rod member, a U-shaped or U An elastically deformable leaf spring-like locking member bent into a letter shape is used. In the connection structure using such a leaf spring-like locking member, for example, as shown in FIGS. 5A and 5B, a U-shaped or U-shaped leaf spring-like locking member 50 is used. One side piece portion 50a is closely attached to and supported by the inner peripheral surface of one rod member 51, and is provided at the end portion of the other side piece portion 50c projecting in a cantilever shape from the intermediate piece portion 50b. A pair of rod members is formed by causing the locking projection 50d to protrude outward from the outer peripheral surface of one rod member 51 and to be locked in a locking hole 53 formed on the peripheral surface of the other rod member 52. 51 and 52 are connected (refer to FIG. 5A).

  Further, from the state in which the locking projection 50 d is locked in the locking hole 53, the locking projection 50 d is moved to the center of one rod member 51 against the urging force of the plate spring-like locking member 50. While pushing into the shaft side (see FIG. 5B), a force for pushing and pulling out one rod member 51 with respect to the other rod member 52 is loaded, so that the locking protrusion 50d and the locking hole 53 are loaded. The pair of rod members 51 and 52 can be disassembled by releasing the engagement state with the other, or the length of the handle can be changed by engaging the engagement protrusion 50d with the other engagement hole 53. Can be done.

  However, in the conventional handle connecting structure using the U-shaped or U-shaped leaf spring-shaped locking member 50, the locking projection 50d protrudes from the intermediate piece 50b in a cantilever shape. In addition, since it is provided at the end of the other side piece portion 50c, the locking projection 50d moves forward and backward in a direction perpendicular or substantially perpendicular to the central axis of the one rod member 51 by being pushed. Instead, as shown in FIG. 5 (b), while the other side piece portion 50c is turned downward, it is inclined in a state where it is inclined in the direction of rotation about the joint portion with the intermediate piece portion 50b. Will move forward and backward. For this reason, in particular, at the tip side portion of the other side piece portion 50c where the amount of rotation or bending increases, the locking projection 50d becomes less locked with the locking hole 53, and the locked state is maintained. It becomes difficult to hold stably. Such an unstable locking state becomes more prominent when the plate spring-shaped locking member 50 and the locking hole 53 are repeatedly attached and detached.

In the present embodiment, the accommodating portion 15 is formed as a concave groove having a two-stage structure that opens in the outer peripheral surface of one rod member 12 and extends in the length direction of the one rod member. That is, as shown in FIGS. 4A and 4B, the accommodating portion 15 has a narrow width portion 15c on the opening portion 15b side in which the width in the length direction of one rod member is small, The rod member is formed as a concave groove having a convex longitudinal cross-sectional shape including a long width portion 15d on the bottom surface 15a side in which the width in the length direction of the rod member is increased. The accommodating portion 15 is formed so that the groove width in the width direction of one of the rod members is, for example, about 10 to 50 mm, and the bottom surface 15a formed by the long width portion 15d faces away from the opening 15b. It is formed as a ditch | groove which has the depth which is arrange | positioned close to the outer peripheral surface of this. A leaf spring locking member 14 (to be described later) is provided in the housing portion 15 so that the locking head portion 14a faces the narrow width portion 15c, and the end slide portion 14c of the leaf spring leg portion 14b is disposed on the long width portion 15d. It is installed in the installed state.

  As shown in FIGS. 1 to 3, the other rod member 13 constituting the handle 11 of the cleaning tool 20 is made of a synthetic resin made of, for example, polypropylene, polyacetal, polycarbonate, ABS or the like, like the one rod member 12. It is a molded product or a metal processed product such as aluminum or brass, and has a length slightly longer than the insertion reduced diameter portion 12b of one rod member 12, for example, about 100 to 300 mm. The other rod member 13 is a hollow, substantially cylindrical rod portion having an insertion opening 13c opened on the end surface 13b at one end and the other end closed by an end wall 13d. Further, the other rod member 13 has a long diameter of about 5 to 50 mm, for example, similar to the outer peripheral cross-sectional shape of the tip enlarged diameter portion 12a of the one rod member 12 on the end surface 13b of the one end portion where the insertion opening 13c is formed. It has an elliptical outer peripheral cross-sectional shape having a short diameter, and a shape in which the outer peripheral cross-sectional shape is gradually expanded toward the end wall 13d at the other end. As a result, when the handle 11 is in the contracted state, the outer peripheral surface of the tip enlarged portion 12a of one rod member 12 and the outer peripheral surface of the other rod member 13 are smoothly continuous (FIG. 2). (See (a)). A suspension ring portion 24 is integrally provided on the end wall 13d at the other end of the other rod member 13 so as to be continuous behind the end wall 13d.

  In the present embodiment, the other rod member 13 has a locking hole 16 for locking the locking head portion 14 a of the leaf spring locking member 14 between the outer peripheral surface and the inner peripheral surface of the other rod member 13. Openings are formed in two places through the gap. That is, the locking hole 16 is disposed at the same position in the circumferential direction of the other rod member 13, and is formed at two locations, a portion close to the insertion opening 13c and a portion close to the end wall 13b. Yes. Each of the locking holes 16 has an opening width in the length direction of the other rod member 13, and the length of one rod member 12 of the locking head 14 a of the leaf spring locking member 14 attached to the accommodating portion 15. It is formed to have a shape that substantially matches the protrusion width in the vertical direction. The peripheral edge of the opening of the locking hole 16 is chamfered by a tapered surface 16a whose entire circumference or part thereof is inclined obliquely inward from the outer peripheral surface of the other rod member 13 toward the inner peripheral surface. preferable.

  Furthermore, in this embodiment, the hollow interior 13a of the other rod member 13 is a non-circular, for example, substantially rectangular shape, of the insertion reduced diameter portion 12b, which is a portion inserted into the hollow interior 13a of the one rod member 12.

Further, in the present embodiment, the locking holes 16 are respectively formed in the same corner portion of the substantially rectangular inner peripheral cross-sectional shape of the hollow interior 13 a of the other rod member 13, and the leaf spring locking member 14. The opening 15b of the accommodating portion 15 to which is attached is formed at a corner portion of the substantially rectangular outer peripheral cross-sectional shape of the insertion reduced diameter portion 12b of the one rod member 12.

  The insertion reduced diameter portion 12b of one rod member 12 and the hollow interior 13a of the other rod member 13 have a non-circular outer peripheral cross-sectional shape and an inner peripheral cross-sectional shape. In a state where at least the tip portion of the portion 12b is inserted into the hollow interior 13a of the other rod member 13, the one rod member 12 does not rotate with respect to the other rod member 13. It becomes possible to align the locking head 14a of the leaf spring locking member 14 mounted on the portion 15 more smoothly. Further, in particular, the locking hole 16 is formed in the corner portion of the substantially rectangular inner peripheral cross-sectional shape of the hollow interior 13a, and the opening portion 15b of the accommodating portion 15 from which the locking head portion 14a protrudes is the insertion reduced diameter portion. 12b is formed in the corner portion of the substantially quadrangular outer peripheral cross-sectional shape, at the start of insertion of the insertion reduced diameter portion 12b, the corner portion of the insertion reduced diameter portion 12b in which the opening 15b of the accommodating portion 15 is formed, Inserting the reduced diameter portion 12b of one rod member 12 into the hollow interior 13a of the other rod member 13 more smoothly while aligning with the circumferential position of the other rod member 13 in which the locking hole 16 is formed. It will be possible to go.

  The leaf spring locking member 14 that locks one rod member 12 and the other rod member 13 includes a locking head 14a and a locking head as shown in FIGS. It is formed including a pair of leaf spring legs 14b provided so as to protrude from both sides of the base end of the head 14a. In the present embodiment, the leaf spring locking member 14 is attached to the above-described accommodating portion 15 formed at the end opposite to the handle-side joining portion 21b of one rod member 12, and has a two-stage structure. The locking head portion 14a is made to face the narrow width portion 15c of the accommodating portion 15 which is a groove, and the end slide portion 14c of the leaf spring leg portion 14b is disposed on the long width portion 15d, It is installed in a state that does not fall out.

  The leaf spring locking member 14 is a synthetic resin molded product made of, for example, polyacetal, polyamide, polypropylene, or the like, and has a thickness that is slightly smaller than the groove width of the housing portion 15 and substantially the same as this. It is formed. As shown in FIG. 4A, the leaf spring locking member 14 has a locking head portion 14a having a substantially rectangular front shape in which a pair of corner portions on the distal end side are chamfered in an arc shape. A pair of leaf spring legs 14b provided so as to continuously protrude from the pair of corners on the base end side of the head 14a on both sides have a substantially quadri-circular front shape. Further, the leaf spring locking member 14 has a line-symmetric front shape with a center line cc that divides the locking head portion 14a into two equal parts to the left and right, and an axis of symmetry. End slide portions 14c are provided at the distal end portions of the pair of leaf spring legs 14b. The end slide portions 14c are formed by bending the distal end portions outward to form a contact surface that can slide with the bottom surface 15a of the accommodating portion 15. It has been.

  In addition, the leaf spring locking member 14 extends in the length direction of one rod member 12 in the extending direction of the pair of leaf spring legs 14b protruding from the base end portion of the locking head portion 14a to both sides. The end slide portion 14c of the leaf spring leg portion 14b is moved along the bottom surface 15a of the long width portion 15d of the accommodating portion 15 in the length direction of the one rod member 12 by being along the extending direction of the accommodating portion 15. The container 15 is mounted so that it can be slid. Accordingly, the leaf spring locking member 14 slides the end slide portion 14c of the leaf spring leg portion 14b along the bottom surface 15a of the accommodating portion 15 while elastically deforming the pair of leaf spring leg portions 14b. By widening or narrowing the distance between the pair of end slide portions 14c, the locking head portion 14a can be advanced and retracted in the direction X toward the central axis of the one rod member 12 (FIG. 4 ( a) and (b)). Since the end slide portion 14c of the leaf spring leg portion 14b is slid in the length direction of one rod member, the locking head portion 14a is easily directed toward the central axis of the one rod member 12. It becomes possible to push in.

  In order to form the handle 111 by connecting the pair of rod members 12 and 13 by the handle connecting structure 10 having the above-described configuration, for example, one rod member 12 and the other rod member 13 shown in FIG. From the state, the locking head 14a of the leaf spring locking member 14 mounted on the accommodating portion 15 of the insertion reduced diameter portion 12b of the one rod member 12 protrudes outward from the outer peripheral surface of the one rod member 12. Is pushed against the urging force of the leaf spring leg portion 14b with the finger toward the center axis side, and the insertion reduced diameter portion 12b of one rod member 12 is aligned with the locking head portion 14a in the locking hole 16. However, it inserts into the hollow interior 13a of the other rod member 13 through the insertion opening 13c of the end face 13b. When the insertion reduced diameter portion 12b is inserted into the other rod member 13 and the engaged locking head 14a reaches the locking hole 16 on the insertion opening 13c side, the locking head 14a It is pushed outward by the urging force of the portion 14 b and is locked in the locking hole 16. This makes it possible to connect one rod member 12 and the other rod member 13 with the handle 11 extended (see FIGS. 3A and 3B).

  Further, from the state in which the handle 11 is extended, the locking head 14a of the leaf spring locking member 14 locked in the locking hole 16 is moved toward the central axis against the urging force of the leaf spring leg 14b. The locking state between the locking head 14a and the locking hole 16 is released by applying a force that pushes and pulls out one rod member 12 with respect to the other rod member 13 with a finger. It becomes possible. For example, by pushing out one rod member 12 and further inserting the insertion reduced diameter portion 12b into the hollow interior 13a of the other rod member 13, the pushed-in locking head portion 14a is engaged with the end wall 13d side. When reaching the stop hole 16, the locking head 14 a is pushed outward by the urging force of the leaf spring leg 14 b and is locked in the locking hole 16. Thereby, it becomes possible to connect one rod member 12 and the other rod member 13 in a state in which the handle 11 is contracted (see FIGS. 2A and 2B).

  According to the handle connecting structure 10 of the present embodiment having the above-described configuration, the pair of rod members 12 and 13 can be attached and detached in a more stable state by using the elastically deformable leaf spring locking member 14. Can be connected and integrated.

  That is, according to the present embodiment, the leaf spring locking member 14 accommodated in the accommodating portion 15 is provided with a pair of locking heads 14a and a pair of protrusions provided on both sides of the locking head 14a. The leaf spring leg portions 14b are formed to slide the end slide portions 14c of the leaf spring leg portions 14b along the bottom surface 15a of the housing portion 15 while elastically deforming the pair of leaf spring leg portions 14b. Thus, the locking head 14a is advanced and retracted in the direction X toward the central axis of the one rod member 12 by widening or narrowing the distance between the pair of end slide portions 14c.

  Therefore, the leaf spring locking member 14 housed in the housing portion 15 is engaged with the locking hole 16 of the other rod member 13 by causing the locking head 14 a to protrude outward from the outer peripheral surface of the one rod member 12. From the stopped state (see FIG. 4A), when the locking head portion 14a is pushed into the central axis side of the one rod member 12, the end portion of the side piece portion protruding in a cantilever shape is formed. Like a U-shaped or U-shaped leaf spring-shaped locking member provided with a locking projection (see FIGS. 5A and 5B), it moves forward and backward in an inclined state. And the rod member 12 can move forward and backward in a direction perpendicular or substantially perpendicular to the central axis of the one rod member 12 (see FIG. 4B). It becomes possible to connect and integrate detachably in a state.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary that the other rod member is formed with a plurality of locking holes at intervals in the length direction, and one rod is connected to the other rod member in which only one locking hole is formed. The present invention can also be adopted when connecting members. In addition, the leaf spring locking member does not necessarily need to be mounted so that the end slide portion of the leaf spring leg portion is slid in the length direction of one rod member, for example, in the circumferential direction of one rod member. It can also be attached to slide. Furthermore, the outer peripheral cross-sectional shape of the portion of one rod member inserted into the hollow interior of the other rod member and the inner peripheral cross-sectional shape of the hollow interior of the other rod member are substantially rectangular, oval or triangular. Other various non-circular outer peripheral cross-sectional shapes can be used, and the outer peripheral cross-sectional shape and the inner peripheral cross-sectional shape can be circular cross-sectional shapes.

  Furthermore, the housing portion to which the leaf spring locking member is mounted does not necessarily have to be a concave groove having a two-stage structure composed of a narrow width portion and a long width portion. The housing portion may have various other shapes that can be mounted in a state where the head protrudes outward and does not fall out. For example, when the portion of one rod member that is inserted into the hollow interior of the other rod member is formed as a hollow pipe-shaped portion, this hollow interior can also be used as the accommodating portion. it can. The handle connecting structure of the present invention is not limited to the handle of the cleaning tool, and other various handles such as a cane handle are adopted as a structure formed by connecting and integrating a pair of rod members in the axial direction. can do.
