Cleaning equipment

The present invention relates to a cleaning tool, and more particularly to a cleaning tool used in wiping and cleaning a cleaning place.

As a cleaning tool used for wiping and cleaning in a cleaning place, cleaning tools of various structures are proposed. For example, Patent Document 1 described later discloses a cleaning tool including a rag body that can detachably hold a cleaning sheet. The cleaning tool disclosed in Patent Document 1 is provided with a wavy zigzag slit that can be detachably locked to the cleaning sheet on the upper surface of the rag main body. The wavy serrated slits are formed by mutually occluded and elastically deformable wave serrations. When the rag body is loaded with the cleaning sheet, the cleaning sheet is pressed between the serrated slits by the user's fingers. Thereby, the sheet is cleaned and held in a state of being sandwiched between the serrations constituting the zigzag slit.

[Patent Document 1] Japanese Shikai Hira 6-62960

In the cleaning tool disclosed in Patent Document 1, in order to mount the cleaning sheet on the rag main body, it is necessary to press the cleaning sheet between the serrated slits by the user's finger. At this point, the user's finger is clipped to the wavy jagged Between the slits of the slits. Therefore, it is conceivable that the user reduces the amount of pressing of the finger toward the serrated slit so that the finger is not caught between the slits of the serrated slit. At this time, the amount of pressing of the cleaning sheet between the jagged slits is insufficient, and the cleaning sheet is peeled off from the serrated slit during cleaning. Moreover, as a method of reducing the pressure applied to the finger of the user, it is conceivable to reduce the holding force of the cleaning sheet by the serration. However, this method cannot be used because the cleaning sheet cannot be maintained with sufficient holding force.

An object of the present invention is to provide a cleaning tool having a sheet holding member that can detachably hold a cleaning sheet, and to provide a technique for effectively improving the mounting property of the cleaning sheet.

The cleaning tool of the present invention comprises a sheet holding member having a locking member that can lock the cleaning sheet to be detachably attached. The locking member is typically configured to be detachably locked to the end of the cleaning sheet attached to the sheet holding body. Further, the cleaning tool may be configured by a sheet holding body and a grip, or a sheet holding body, a grip, and a connecting member that connects the sheet holding body and the grip.

As a cleaning sheet, a sheet having a function of scraping the dirt on the cleaning surface when the cleaning surface for cleaning is cleaned is used. Typically, a sheet-like nonwoven fabric composed of a heat-fusible fiber (thermoplastic fiber), or in place of the nonwoven fabric or the nonwoven fabric, and a urethane, a sponge, a woven fabric, a mesh fabric, and a mesh reinforcement are used. The material processor is used as a cleaning sheet. As a hot melt fiber (heat As the plastic fiber, polyethylene, polypropylene, polyethylene terephthalate or the like can be used. As the non-woven fabric, a manufacturer such as a gas flow method, a spunbonding method, a hot melt method, a spray method, a point stick method, a melt blow method, a stitchbonding method, a chemical non-woven hot melt method, or a needle rolling can be suitably used. The cleaning tool of the present invention may or may not contain a cleaning sheet.

The locking member that locks the cleaning sheet is typically formed of a resin material. The locking member includes an insertion space into which a user's finger can be inserted, and an edge portion connected to the insertion space, and can bite the slit of the cleaning sheet. The "edge portion of the insertion space" corresponds to, for example, a wall forming an insertion space. Further, the "slit formed in the insertion space" corresponds to, for example, a slit provided in a wall forming the insertion space or a slit extending from a wall forming the insertion space. The slit is formed by inserting a user's finger into the insertion space, and the slit interval is increased, and the slit interval is reduced by releasing the insertion of the user's finger. Thereby, the cleaning sheet inserted into the insertion space by the user's finger is locked in a state of being bitten between the slits. The slits are typically formed by concave and convex portions that are arranged to face each other and bite each other. The shape of the uneven portion constituting the slit can be appropriately selected.

In the cleaning tool of the present invention, the slit for the cleaning sheet is not provided in the insertion space into which the user's finger is inserted.

Thereby, the first constituent piece 121 and the second constituent piece 122 which are combined together can be easily attached to a specific position on the side of the cleaning head 110. Further, instead of the engagement piece 121c of the first constituent piece 121 and the engagement piece 122c of the second constituent piece 122, the engagement hole may be engaged with the engagement hole of the cleaning head 110 side.

Next, the operation of attaching the cleaning sheet 200 to the cleaning head 110 will be described with reference to Figs. 9 to 12 . FIG. 9, FIG. 10, and FIG. 12 are views for explaining an operation when the cleaning sheet 200 is inserted into the insertion port 125a (insertion space 125) by the user's finger F. Further, Fig. 11 is a plan view of the locking member 120 in the state shown in Fig. 10.

When the cleaning sheet 200 is mounted on the cleaning head 110, first, it is to be cleaned. The sheet 200 is attached to the outer circumference of the cleaning head 110. Next, as shown in Fig. 9, from the cleaning sheet 200 attached to the outer periphery of the cleaning head 110, the user's finger F is directed toward the insertion opening 125a (insertion space 125) of the locking member 120 (Fig. 9) Knock out the arrow direction) Insert (press in). Thereby, the sheet 200 is cleaned and inserted into the insertion space 125 together with the finger F of the user. The finger F of the user inserted in the insertion space 125 sandwiches the cleaning sheet 200, and the second wall 124 (guide wall 128) of the first constituent piece 121 constituting the insertion space 125 and the second component piece 122 are second. The wall 124 (guide wall 128) is pressed toward the separation direction. As a result, the second wall 124 of the first constituent piece 121 and the second wall 124 of the second constituent piece 122, as shown in FIGS. 10 and 11 , overcome the elastic force and are directed away from each other (Fig. 10). And the black arrow direction of Figure 11 is elastically deformed. In the present embodiment, the cross-sectional shape of the insertion space 125 is formed to have a curved shape having a long diameter line and a short diameter line, and the first constituent piece 121 and the second constituent piece 122 are disposed opposite to each other in the long diameter line. The sides of the parallel line. Therefore, the first constituent piece 121 and the second wall 124 of the second constituent piece 122 are such that the interval in the direction in which the first constituent piece 121 and the second constituent piece 122 face each other is increased (the short diameter of the insertion port 125a is changed). The big way) elastic deformation. In the first embodiment, the first constituent piece 121 of the first constituent piece 121 and the second constituent piece 122 is placed along the direction in which the first constituent piece 121 and the second constituent piece 122 face each other, and the insertion opening 125a is interposed therebetween. Since the opening portion 127 is provided at the opposite side (the insertion space 125), the elastic deformation is easy to perform.

By the elastic deformation of the second wall 124 of the first constituent piece 121 and the second constituent piece 122, the interval between the slits of the sheet fixing slits 129 is increased (refer to Fig. 10), and the thinner fixing auxiliary slits 126 are thin. The seam interval will also become larger (see According to Figure 11). At this time, the cleaning sheet 200 inserted into the insertion space 125 by the user's finger F enters between the slits of the sheet fixing slits 129 and the slits of the sheet fixing auxiliary slits 126.

In the present embodiment, the second wall 124 of the first constituent piece 121 and the second constituent piece 122 has a base end portion 128a on the insertion port 125a side as a support point, and a front end portion 128b opposite to the base end portion 128a. It is constructed as a free end. Further, the second wall 124 of the first constituent piece 121 and the second wall 124 of the second constituent piece 122 are oriented in a direction orthogonal to the direction in which the first constituent piece 121 and the second constituent piece 122 face each other (the length of the insertion space 125) In the radial direction, the interval a between the insertion spaces 125 is gradually decreased from the insertion port 125a side toward the distal end side, and extends obliquely with respect to the axial direction of the insertion space 125. When the user's finger F is inserted into the insertion space 125, the front end portion 128b of the second constituent member 121 and the second constituent member 122 of the second constituent member 122 are oriented toward each other with the proximal end portion 128a as a supporting point. Deformation in the direction of separation. In other words, the load applied to the user's finger F when the second wall 124 of the first constituent piece 121 and the second constituent piece 122 is deformed in the separation direction can be suppressed. Therefore, since the user can insert the finger F deeper into the insertion space 125, the cleaning sheet 200 can be surely maintained.

Then, the finger F of the user inserted in the insertion port 125a (insertion space 125) is pulled out (the direction of the hollowing arrow in FIG. 12), and the first constituent piece 121 and the second constituent piece 122 which are formed in the insertion space 125 are released. The second wall 124 is pressed in the separation direction. As a result, the first constituent piece 121 and the second wall 124 of the second constituent piece 122 are restored to the state shown in FIG. 9 by the elastic force. That is, the sheet fixing slits 129 and the sheet fixing auxiliary slits 126 are closed. this In the state where the end portion of the cleaning sheet 200 enters between the slits of the sheet fixing slits 129 and the slits of the sheet fixing auxiliary slits 126, the sheet fixing slits 129 and the sheet fixing auxiliary slits 126 are closed. Therefore, the cleaning sheet 200 is in a state of being bitten in the uneven portion 129a of the sheet fixing slit 129 and the uneven portion 126a of the sheet fixing auxiliary slit 126 (refer to Fig. 12). That is, the cleaning sheet 200 is held by the cleaning head 110. Further, it is preferable that the uneven portion 129a constituting the sheet fixing slit 129 and the uneven portion 126a constituting the sheet fixing auxiliary slit 126 are formed in all or part of the surface. Thereby, since the cleaning sheet 200 can be held by the strong force, it is possible to prevent the cleaning sheet 200 from falling off from the cleaning head 110 when the wiping cleaning is performed. The sheet region to which the sheet fixing slit 129 is locked is a sheet region in which the sheet fixing auxiliary slit 126 is locked in association with the "first sheet region" of the present invention, and is the same as the "first sheet" of the present invention. 2 sheet area" corresponds.

As described above, the locking member 120 of the present embodiment forms the insertion space 125 inserted by the user's finger, and the sheet fixing slit 129 for locking the cleaning sheet 200 or the sheet fixing auxiliary slit 126 The formed slit is formed to be connected to the edge of the insertion space 125. That is, the slit is formed in a region different from the insertion space 125. Thereby, the attachment property of the cleaning sheet 200 can be improved, and the cleaning sheet 200 can be surely locked.

Further, in the present embodiment, the second wall 124 into which the insertion space 125 of the cleaning sheet 200 is inserted is obliquely extended with respect to the axial direction of the insertion space 125 (the insertion direction of the cleaning sheet 200), and is formed on the second wall 124. Formed in the direction along the axis of the insertion space 125 (insertion of the cleaning sheet 200) The sheet extending in the direction) fixes the slit 129. Thereby, the cleaning sheet 200 can be easily locked to the sheet fixing slit 129, and the user's finger F is less likely to be caught between the slits of the sheet fixing slit 129.

Further, in the present embodiment, the sheet fixing auxiliary slit 126 which extends in the direction intersecting the axial direction of the insertion space 125 (the insertion direction of the cleaning sheet 200) is formed from the edge portion of the insertion space 125 into which the cleaning sheet 200 is inserted. Thereby, the cleaning sheet 200 can be fixed by at least one of the sheet fixing slit 129 and the sheet fixing auxiliary slit 126, and is preferably locked by both sides.

In particular, the sheet fixing slits 129 and the sheet fixing auxiliary slits 126 are formed by jagged or zigzag-shaped uneven portions 129a and 126a which are engaged with each other. Thereby, the cleaning sheet 200 can be strongly held by the sheet fixing slits 129 and the uneven portions 129a and 126a of the sheet fixing auxiliary slit.

Further, the first constituent piece 121 and the second constituent piece 122 constituting the holding member 120 may be formed as separate bodies or may be integrally formed. For example, as shown in Fig. 13, the first constituent piece 121 and the second constituent piece 122 can be connected to each other by a connection portion 121d having a small thickness. When such an individual structure is used, the first constituent piece 121 and the second constituent piece 122 are folded toward each other in the direction in which the connecting portion 121d approaches each other.

Moreover, the shape, the number, the arrangement position, and the like of the sheet fixing slit 129 or the sheet fixing auxiliary slit 126 of the first constituent sheet 121 and the second constituent sheet 122 can be appropriately changed as necessary. For example, the height or the interval of the mountain or valley of the uneven portion 129a or the uneven portion 126a can be changed on the first constituent sheet 121 side and the second constituent sheet 122 side. As a method of forming the uneven portion, it is not limited In the method of forming a zigzag shape or a zigzag shape, a method of forming a fine uneven shape on the surface by surface treatment, a method of forming an uneven shape by embossing, or the like can be used. Further, in Fig. 14, a cross-sectional view of the first constituent piece 221 and the second constituent piece 222 of the other embodiment is shown. As shown in Fig. 14, by setting the sheet fixing auxiliary slits 126 to the upper and lower stages, the locking force (holding force) of the cleaning sheet 200 can be improved.

Next, the configuration of the pipe 130 will be described with reference to Figs. 15 to 17 . The pipe material 130 of the present embodiment is configured by connecting at least two pipe members (the first pipe member 130a and the second pipe member 130b). In Fig. 15, a cross-sectional view of the interlocking latch mechanism 132 is shown. In the sixteenth diagram, a cross-sectional view of the first latching member 133 and the second latching member 134 that constitute the link latch mechanism 132 is shown. In Fig. 17, a view of the tube 130 of Fig. 16 as seen from the direction of the arrow C is shown. Further, the shapes of the first pipe member 130a and the second pipe member 130b may be the same or different. Further, the number of the pipe members constituting the pipe member 130 may be three or more.

The first pipe member 130a and the second pipe member 130b are connected by inserting one pipe member into the inside of the other pipe member. That is, one of the pipe members is formed as a male side member, and the other pipe member is formed as a female side member. In the present embodiment, as shown in Figs. 15 to 17 , the end portion on one side of the first pipe member 130a (the end portion on the left side in Figs. 15 to 17) is inserted in the second. The other end of the pipe member 130b (the end portion on the right side in Figs. 15 to 17) is inside. That is, the one end side of the first pipe member 130a is formed as a male side member, and the other side end of the second pipe member 130b is formed. It is formed as a female side member. In this case, the inner diameter of the other end portion (female side member) of the second pipe member 130b is set to be the same as the outer diameter of the end portion (male side member) on one side of the first pipe member 130a, or Slightly larger. Further, the male side member is formed at one end portion of the first pipe member 130a, and the female side member is formed at the other end portion, and the female portion is formed at the other end portion of the second pipe member 130b. It is preferable that the side member has a male side member formed at one end portion. At this time, the number of connections of the pipe members (the length of the pipe 130) can be easily adjusted.

The first pipe member 130a and the second pipe member 130b are made of a hard material, typically a metal material such as an aluminum group, a stainless steel group, or an iron group. A resin material or the like is formed into a cylindrical shape. As the cross-sectional shape of the first pipe member 130a and the second pipe member 130b, various shapes such as a perfect circle, an ellipse, and a polygon (for example, a triangle, a square, a trapezoid, or a regular hexagon) can be selected. Further, the outer diameter, the inner diameter, and the length of the first pipe member 130a and the second pipe member 130b can be appropriately selected.

The connection latch mechanism 132 has a function of locking the connection state of the first pipe member 130a and the second pipe member 130b. In the present embodiment, the connection latch mechanism 132 is the first latch member 133 attached to the end portion (male side member) on one side of the first pipe member 130a, as shown in Figs. 15 to 17 And a second latching member 134 attached to the other end (female side member) of the second pipe member 130b. In a state in which the first latching member 133 is engaged with the second latching member 134, the state in which the first tubular member 130a and the second tubular member 130b are locked is locked and locked. another On the other hand, in a state in which the engagement between the first latching member 133 and the second latching member 134 is released, the interlocking state in which the connection state of the first tubular member 130a and the second tubular member 130b is released is released. The first latching member 133 and the second latching member 134 are made of a resin material, typically polyethylene resin (PE), polypropylene resin (polypropylene), polypropylene resin. Butadiene. A resin material such as acrylonitorile butadiene styrene resin, polyacetal resin (POM), or urethane resin is integrally molded.

The first latch member 133 is attached to the inner peripheral side of the end portion (male side member) on one side of the first pipe member 130a. An insertion hole 135 that communicates the inner circumferential side and the outer circumferential side is formed at one end side of the first pipe member 130a. The first latching member 133 is provided with an engaging projection 136. When the first latching member 133 is attached to the inner peripheral side of the first tubular member 130a, the upper surface of the engaging projection 136 passes through the insertion hole 135 of the first tubular member 130a and protrudes from the outer peripheral surface of the first tubular member 130a. . The upper surface of the engagement projection 136 of the first latch member 133 is inclined downward toward the tube end surface 130c side of the first pipe member 130a. Further, the engaging projection 136 is constituted by the support portion 136a as a center, and the upper surface thereof is configured to have an elastic force acting in a direction protruding from the insertion hole 135. When the upper surface of the engaging projection 136 is pressed toward the inner direction of the first pipe member 130a, the engaging projection 136 overcomes the elastic force and faces the inside of the first pipe member 130a with the support portion 136a as the center. Move in direction. On the other hand, when the pressing toward the upper surface of the engaging projection 136 is released, the engaging projection 136 is elastically biased. The support portion 136a is moved toward the outside of the first pipe member 130a.

Further, the first latching member 133 includes a pipe end surface 130c that is in contact with the first pipe member 130a, and covers (caps) the end portion 133a before the pipe end surface 130c. When the first latching member 133 is attached to the inner peripheral side of the first tubular member 130a, the distal end portion 133a does not escape from the outer peripheral surface of the tubular end surface 130c of the first tubular member 130a by the outer peripheral surface of the distal end portion 133a. The method is ideal. Further, it is preferable that the outer peripheral surface of the distal end portion 133a is formed such that the outer diameter thereof is increased toward the tubular end surface 130c side from the distal end side (the second tubular member 130b side). Typically, a taper shape is formed. The distal end portion 133a corresponds to the "first covering member" that covers the pipe end surface 130c of the first pipe member 130a.

The second latch member 134 is attached to the outer peripheral side of the other end (female side member) of the second pipe member 130b. An insertion hole that communicates the inner circumferential side and the outer circumferential side is formed at the other end portion of the second pipe member 130b. In the second latching member 134, when the second latching member 134 is attached to the outer peripheral side of the second tubular member 130b, a communication inner circumference is formed at a position facing the insertion hole formed in the second tubular member 134. Engagement holes 137 on the side and the outer circumference side. The insertion hole formed in the second pipe member 130b and the engagement hole 137 formed in the second latch member 134 are formed to have the size of the front end portion of the engagement projection 136 into which the first latch member 133 can be inserted. Further, the second latching member 134 is provided with a pressing piece 138 that extends so as to cover the upper portion of the engaging hole 137. Thereby, the first pipe member 130a and the second pipe member 130b are coupled, and the engaging projection 136 is inserted into the engaging hole of the second pipe member 130b. In the state of the link lock of 137, by pressing the pressing piece 138, the engaging projection 136 can be moved toward the inner direction of the second pipe member 130b. By using such a configuration, the user's finger is less likely to enter the engagement hole 137 than when the engagement projection 136 is directly pressed.

Further, the second latching member 134 is provided with a distal end portion 134a that covers the tubular end surface 130d of the second tubular member 130b and covers (covers) the tubular end surface 130d. When the second latching member 134 is attached to the outer peripheral side of the second tubular member 130b, the inner peripheral surface of the distal end portion 134a does not escape from the inner peripheral surface of the tubular end surface 130d of the second tubular member 130b. The method is ideal. In addition, it is preferable that the inner peripheral surface of the distal end portion 134a is formed such that the inner diameter thereof is smaller toward the tubular end surface 130d side from the distal end side (the first tubular member 130a side). Typically, it is tapered. The distal end portion 134a corresponds to the "second covering member" that covers the pipe end surface 130d of the second pipe member 130b.

Further, the pressing piece 138 is preferably formed such that the area of the surface that is in contact with the upper surface of the engaging projection 136 is larger than the area of the upper surface of the engaging projection 136. By using such a configuration, the engagement protrusion 136 can be pressed with a smaller force than when the engagement protrusion 136 is directly pressed. Further, when the pressing piece 138 is pressed toward the inner direction of the second pipe member 130b, it is preferable to be configured to be able to enter the engaging hole 127. By using such a configuration, when the engagement protrusion 136 is pressed by the pressing piece 138, the engagement protrusion 136 can be pressed deeper toward the inside of the second pipe member 130b, and the first pipe member 130a and the first pipe member can be easily released. 2 The connection state of the pipe member 130b is locked.

Further, in the present embodiment, the pipe end surface 130c of the first pipe member 130a is covered (capped) by the first latch member 133 formed of a resin material, and the pipe end face 130d of the second pipe member 130b is The second latch member 134 formed of a resin material covers (cover). Specifically, the pipe end surface 130c of the first pipe member 130a is covered (capped) by the front end portion 133a of the first latch member 133. Further, the pipe end surface 130d of the second pipe member 130b is covered (capped) by the front end portion 134a of the second latch member 134. By using such a configuration, the pipe end surface 130c of the first pipe member 130a formed of the metal material and the pipe end surface 130d of the second pipe member 130b are not exposed. Thereby, the connection locking operation (assembly work of the pipe 130) for locking the connection state of the first pipe member 130a and the second pipe member 130b or the connection lock release operation of the connection lock state (the pipe 130) can be easily performed. Decomposition work). In particular, in the present embodiment, the first latching member 133 and the second latching member 134 that constitute the interlocking mechanism 132 that locks the connection state between the first tubular member 130a and the second tubular member 130b are used for the first time. A cover member (cover member) of the pipe end surface 130c of the pipe member 130a and the pipe end face 130d of the second pipe member 130b. Thereby, the number of parts can be reduced.

Further, in the present embodiment, the outer peripheral surface of the distal end portion 133a of the first latching member 133 is changed from the tubular end surface 130c side toward the distal end side (in the direction inserted into the inside of the second tubular member 130b). Small cone shape. In addition, the inner peripheral surface of the front end portion 134a of the second latching member 134 has a tapered shape which is smaller from the distal end side toward the tubular end surface 130d side (in the direction in which the first tubular member 130a is inserted). By using such a composition The one end side of the first pipe member 130a can be smoothly inserted into the other end portion of the second pipe member 130b.

Moreover, when the first pipe member 130a and the second pipe member 130b are connected, the insertion position of the engagement projection 136 of the first latching member 133 (the virtual position shown by the two-dotted line in FIG. 17) is used as a reference. It is preferable that the conspicuous mark (symbol) of the target is provided to the second latch member 134. For example, as shown in FIG. 17, the mark 139 is provided in the second latch member 134. In the mark 139 shown in Fig. 17, an arrow indicating the insertion position or the insertion direction of the engaging projection 136 corresponding to the first latching member 133 of the second latching member 134 is used. The mark 139 is formed, for example, by processing a concave portion or a convex portion on the outer circumferential surface of the second locking member 134 or by drawing a pattern on the outer circumferential surface. As the marker, the insertion position of the engagement projection 136 corresponding to the first latching member 133 of the second latching member 134 can be displayed, and is not limited to the arrow, and points (solid dots), lines, and others can be used. A pattern or mark of shape. Further, the mark is not limited to the outer circumferential surface of the second latching member 134, and may be provided at the front end portion 134a. Further, the method of forming the mark is not limited to the method of applying the concave portion or the convex portion to the outer circumferential surface of the second latching member 134, and the method for punching the second latching member 134 may be used. 2 The front end portion 134a of the latch member 134 is subjected to a slit or groove processing method. Further, a mark may be provided to the second latch member 134 and the first latch member 133 (or the first tube member 130a).

Next, a connection locking operation (assembly work of the pipe 130) for locking the connection state of the pipe member by the connection locking mechanism 132 and a pipe member by the connection locking mechanism 132 will be described with reference to FIGS. 18 and 19; The link card lock release operation of the link lock state (decomposition of the pipe 130).

In the eighteenth aspect, the interlocking operation of the present embodiment in which the first pipe member 130a is coupled to the second pipe member 130b and the lock connection state is shown is shown. In the interlocking operation, first, the first pipe member 130a and the second pipe member 130b are disposed to face each other. At this time, the first pipe is determined such that the engaging projection 136 of the first latching member 133 faces the mark (for example, the mark 139 provided in the second latching member 134 shown in FIG. 17). The position of the member 130a (the first latching member 133) and the second pipe member 130b (the second latching member 134) is preferable. Thereby, the link locking operation can be performed smoothly. This method is particularly effective when the number of pipe members is large. Next, the one end side (male side member) of one side of the first pipe member 130a is inserted into the other end (female side member) of the second pipe member 130b. At this time, as shown in Fig. 18, the engagement projection 136 of the first latching member 133 is pressed toward the inner side of the first tubular member 130a by being in contact with the front end portion 134a of the second latching member 134. . Thereby, the engaging projection 136 overcomes the elastic force and is pressed toward the inner direction of the first pipe member 130a with the support portion 136a as the center.

In the present embodiment, the upper surface of the engaging projection 136 is formed to be inclined (tapered) toward the distal end side (in the direction in which the first tubular member 130a is inserted into the second tubular member 130b). The strength of the inside of one end side (male side member) of the other side of the second pipe member 130b (the male side member) is smoothly changed to the engaging protrusion 136. Press the pressing force. Again, the second card lock The inner peripheral surface of the front end portion 134a of the member 134 is preferably formed in a shape corresponding to the upper surface of the engaging projection 136 (for example, an inclined surface having the same inclination angle). Thereby, the pressing action of the engaging projection 136 becomes smoother.

When the engaging projection 136 of the first latching member 133 reaches the insertion hole of the first tubular member 130a and the engaging hole 137 of the second latching member 134, the engaging projection 136 is elastically biased. With the support portion 136a as a center, the inside of the engagement hole 137 moves toward the outer peripheral side of the second pipe member 130b. That is, the engaging projection 136 is inserted into the engaging hole 137. Thereby, the connection state between the first pipe member 130a and the second pipe member 130b is locked, and the connection state shown in Fig. 15 is obtained.

In the 19th view, the interlocking lock releasing operation for releasing the interlocking state of the first pipe member 130a and the second pipe member 130b by the interlocking mechanism 132 is shown. In the interlocking lock release operation, first, the pressing piece 138 is pressed, and the engaging projection 136 is pressed toward the inside of the second pipe member 130b. When the engagement projection 136 is pressed down the engagement hole 137 of the second latch member 134, the interlocking state of the first pipe member 130a and the second pipe member 130b is released. Then, the end portion (male side member) on one side of the first pipe member 130a is taken out from the other end (female side member) of the second pipe member 130b, thereby becoming the 16th and the Figure 17 shows the link lock release status. Further, the pressing piece 138 may be omitted, and the engaging protrusion 136 may be directly pressed.

In the above, the elastic force of the engaging projection 136 itself is utilized, but an elastic member may be additionally provided. For example, as shown in Figure 20, the snap fit The upper surface of the projection 136 protrudes from the outer peripheral surface of the first pipe member 130a through the insertion hole 135, and a spring plate 240 that imparts an elastic force to the engaging projection 136 is used. By using such an elastic member, the elastic force of the engaging projection 136 can be easily imparted.

Further, in the above, the engagement projection 136 is provided on the first latch member 133 side, and the engagement hole 137 is provided on the second latch member 134 side. However, the engagement projection may be provided on the second latch member 134 side. On the side of the first latching member 133, an engaging hole is provided. Further, a combination of the multi-array engaging projection and the engaging hole may be provided. For example, as shown in Fig. 21, the connection latch mechanism 132 can be provided with the first latching member 333 provided with the two engaging projections 136; and the two corresponding to the two engaging projections 136, respectively. The engaging hole 137 and the second latching member 334 of the pressing piece 138 are configured. By using such a configuration, the first pipe member 130a and the second pipe member 130b can be more reliably connected.
