Description

  The present invention relates to a slide lock device used for adjusting the height of a holding head for a shower head, a lamp holding head for a desk lamp, and the like.

  The height of the shower head can be adjusted with respect to the shower bar attached to the wall surface, so that it can be used at a height according to the height and preference of the user.

  The conventional apparatus described in Patent Document 1 uses a ring-shaped handle for height adjustment, and the handle is in contact with the holding table of the shower head between the holding table and the holding table. A brake body for generating a frictional force is provided. The handle is attached by screwing into the holding base, and the frictional force of the brake body is increased or decreased by rotating the handle in the forward / reverse direction in this state. The height of the shower head is adjusted by reducing the frictional force, and the shower head is fixed in place by tightening the handle.

The conventional apparatus described in Patent Document 2 has a structure in which a shower bar is sandwiched between cases, and the case is provided with a handle lever. The handle lever is configured to generate a frictional force between the handle lever and the shower head by pressing the tip of the handle lever against the shower bar by a spring (elastic body) provided in the case. In this apparatus, since the pressing force of the spring is released simply by grasping the handle lever, the shower bar is in a free state and the shower head can be easily moved up and down.
JP 2002-194784 A Japanese Patent Laid-Open No. 9-158273

  By the way, when the slide lock device is used for raising and lowering the shower head, it is unavoidable that shampoo, detergent or hot water falls and enters the inside. Since the shampoo or detergent that has entered the inside is slippery in this way, the shower head may slip and fall from the shower bar, and it will be out of the proper use position and become unusable. In such a case, it is necessary to increase the holding force for holding the shower head to prevent the shower head from being inadvertently lowered. The same applies to desk lamps. When a large lamp is used, the weight of the lamp is large, so that the lamp holding head is inadvertently lowered, and in order to prevent this, the lamp holding head is held. It is necessary to increase power.

  In order to increase such holding force, in the structure of Patent Document 1, it is necessary to increase the frictional force of the brake body by tightly rotating and tightening the ring-shaped handle. Therefore, there is a problem that the operability to the handle is lowered. In addition, since there is a limit to the tightening of the handle, it is impossible to increase the locking force for fixing the shower head and the lamp holding head. Further, since the handle is always accompanied by a rotation operation, the operability is also poor. Furthermore, in order to increase the tightening force of the handle, it is necessary to increase the ring shape of the handle, and the handle protrudes by that amount, so that the appearance of the design is poor.

  In the structure of Patent Document 2, in order to increase the locking force, it is necessary to change to a spring having a large spring force to increase the frictional force, and the operating force to the handle lever increases as the spring force increases. There is a problem that the operability is lowered. Further, there is a limit to increasing the spring force due to the operability of the handle lever, and the locking force cannot be improved. In addition to this, since the spring becomes longer by the amount of spring having a large spring force, the protrusion amount of the handle lever is increased, and the appearance of the design is also deteriorated.

  Furthermore, in any conventional structure, since the structure is complicated and the number of parts is large, in addition to being difficult to assemble to a shower head, a desk lamp or the like, there is a problem that it is difficult to perform maintenance or trouble repair.

  Japanese Patent Application Laid-Open No. 2002-106523 also describes a slide lock device that adjusts the height of a shower head or the like. As described in Japanese Patent Application Laid-Open No. 2004-228688, it is different in that locking and releasing are performed by increasing or decreasing the frictional force.

  The present invention has been made in consideration of the above-described problems of the conventional structure, and the operation force is increased or the lock force is increased due to the increase of the lock force of the shower head, the desk lamp, etc. Therefore, it is not necessary to increase the spring force, the locking can be performed reliably, and the height can be easily adjusted. An object of the present invention is to provide a slide lock device.

  The slide lock device according to claim 1 includes a case that can be moved up and down with respect to the mating member in a state where the mating member has penetrated, a slope formed in the case in an oblique direction to the longitudinal direction of the mating member, and the mating member And at least one lock piece that contacts the mating member, and the lock piece slides relative to the mating member as the case moves up and down relative to the mating member. A wedge mechanism that increases or decreases the frictional force on the member, an elastic body that urges the lock piece to slide in an increasing direction of the frictional force, and the elastic body and the lock piece are connected to lock the urging force of the elastic body. And an operation lever operated to slide the lock piece in a direction in which the frictional force is reduced and transmitted to the piece.

  In the first aspect of the present invention, the counterpart member is a shower bar in which the shower head is raised or lowered, a stand in which the lamp holding head is raised or lowered, and other long objects. The case also serves as a member for directly or indirectly holding the shower head holding member, the lamp holding head, and other holding members.

  According to the first aspect of the present invention, the lock piece of the wedge mechanism slides relatively along the slope of the case as the case moves up and down, and the friction force of the lock piece against the mating member increases or decreases by this slide. On the other hand, the elastic body acts so that the lock piece slides in the direction of increasing frictional force via the operation lever, and the case is held in place by the frictional force of the lock piece based on the wedge action. . The holding of the case caused by the wedge action is different from the structure in which the case is held only by the frictional force generated by the urging force of the elastic body, so that it is not necessary to increase the urging force of the elastic body more than necessary.

  When a downward moving force is applied to the case due to slipping of the shampoo or the like, the weight of the lamp, or the necessity to move the mating member to a lower position in the above-mentioned case holding state A sliding force relative to the inclined surface and the lock piece is generated due to the moving force to the case, whereby the inclined surface of the case acts to press the lock piece more strongly against the counterpart member by the wedge action. For this reason, the frictional force between the lock piece and the mating member increases, the lock piece bites into the mating member, and the locking force of the case increases. As a result, the case does not descend and maintains the stop state at the fixed position. Thus, in the structure in which the case is stopped at a fixed position by the frictional force resulting from the wedge action, it is not necessary to increase the urging force of the elastic body as described above.

  When moving force in the direction opposite to the downward movement of the case (moving force upward) is applied to the case, a relative sliding force in the reverse direction to the above is generated on the slope and the lock piece. Therefore, the frictional force between the lock piece and the mating member is reduced. Therefore, in this direction, the case can be easily moved in the same direction by applying a force against the small frictional force to the case. In this case, since it is not necessary to operate the operation lever, the operability is improved and the usability is improved.

  On the other hand, when the operation lever is operated while the case is held at a fixed position, the lock piece connected to the operation lever slides in a direction in which the frictional force with the counterpart member decreases. For this reason, the case can be moved with a light force with respect to the mating member in any of the upper and lower directions, and the height of the case can be easily adjusted. When the operation of the operation lever is released, as described above, a frictional force between the lock piece and the mating member is generated by the wedge action based on the urging force of the elastic body, so that the case stops at that position. .

  In the invention according to the first aspect as described above, the urging force of the elastic body is applied to the wedge mechanism, and the case is locked by the wedge action of the wedge mechanism. In addition, it is not necessary to increase the operating force due to increasing the locking force, or to use an elastic body having a large urging force to increase the locking force, and the operability is improved. In addition, the height can be easily adjusted, and further, a good design can be achieved without increasing the amount of protrusion.

  The invention according to claim 2 is the slide lock device according to claim 1, wherein the case has an obliquely inclined lock guide long hole for guiding the oblique slide of the lock piece.

  According to the second aspect of the present invention, since the lock guide slot provided in the case guides the slide of the lock piece, the lock piece can be smoothly brought into contact with the mating member.

  The invention according to claim 3 is the slide lock device according to claim 1 or 2, wherein the operation lever has a connecting pin that penetrates the lock piece and an unlocking long hole through which the connecting pin moves. Features.

  In the invention according to claim 3, since the connecting pin transmits the urging force of the elastic body to the lock piece and the lock release guide slot guides the slide of the connecting pin, the lock piece can be smoothly separated from the lock position. it can.

  The invention according to claim 4 is the slide lock device according to any one of claims 1 to 3, wherein the case includes a pair of case bodies that can be divided so as to sandwich the mating member, and the wedge mechanism. The elastic body and the operating lever are arranged in one case body.

  In the invention according to claim 4, the case can be divided into a pair of case bodies, and the mechanical parts including the wedge mechanism, the elastic body, and the operation lever are arranged in one case body, so that the pair of cases It can be made a finished product by assembling the body. Such a split structure not only simplifies the assembly of the slide lock device, but also can be easily assembled to a mating member such as an existing shower or desk lamp, that is, can be easily retrofitted, and is well suited for maintenance and repairs by disassembly. can do.

  A fifth aspect of the present invention is the slide lock device according to any one of the first to fourth aspects, wherein a plurality of the lock pieces are arranged at positions sandwiching a mating member.

  In the invention according to claim 5, the plurality of lock pieces are in a state of sandwiching the mating member, and each generates a frictional force based on the above-described wedge action. Reliable locking is possible.

  A sixth aspect of the present invention is the slide lock device according to any one of the first to fifth aspects, wherein the lock piece or / and the mating member are provided with a concavo-convex process or a friction member. It is characterized by.

  In the sixth aspect of the invention, since the frictional force between the lock piece and the mating member can be adjusted by the uneven processing or the friction member, it is possible to flexibly cope with the raising / lowering operation according to the specifications and requirements.

  According to the present invention, the wedge mechanism is formed by the slope of the case and the lock piece provided between the slope and the mating member, and the case is held in place by the frictional force based on the wedge action of the wedge mechanism. Due to the structure, the case locking force is increased, the case can be reliably locked, and the operability is improved without increasing the operating force due to the increased locking force. The elastic body is used to increase the frictional force between the lock piece of the wedge mechanism and the mating member, and is different from the structure in which the case is held only by the frictional force due to the urging force of the elastic body. It is not necessary to use a large elastic body, the case height can be easily adjusted, and the amount of protrusion caused by the elastic body does not increase, and a compact and good design can be achieved.

  Hereinafter, the present invention will be described in detail based on illustrated embodiments. In each embodiment, the same member is assigned the same reference numeral.

  1 to 7 show a slide lock device 1 according to a first embodiment of the present invention. FIG. 1 is a plan view of the whole, FIG. 2 is a front view, FIG. 3 is a side view, FIG. FIG. 6 shows a lock piece, and FIG. 7 shows an operation lever.

  The slide lock device 1 according to this embodiment includes a case 2, a wedge mechanism 20 including a lock piece 3 and a slope 15, an operation lever 5, and an elastic body 6 including a coil spring.

  The case 2 is formed in a rectangular parallelepiped shape whose outer shape is vertically long, and holds these by attaching a shower head, an electric lamp holding head (not shown) or the like. A vertically long mating member 40 (see FIG. 4 and FIG. 9 to be described later) such as a shower bar or a stand passes through the case 2, and can be moved up and down along the length direction of the mating member 40 in this penetrating state. By raising and lowering the case, the height positions of the shower head and the lamp holding head attached to the case 2 can be adjusted. Since the mating member 40 penetrates, the through passage 7 penetrates the case 2 in the vertical direction. In this embodiment, the case 2 is formed by assembling the first case body 2a and the second case body 2b, both of which are in the shape of a rectangular parallelepiped. It can be divided into case bodies 2a and 2b.

  As shown in FIG. 5, a groove portion 10 for arranging the lock piece 3 is formed in the middle portion of the first case body 2a in the length direction. It is inserted into the groove 10 of the case body 2b. A slope 15 is formed in the groove 10. The slope 15 is formed so as to be oblique with respect to the longitudinal direction of the counterpart member 40. In this embodiment, the slope 15 is inclined at a predetermined oblique angle so as to approach the counterpart member 40 from the bottom to the top. is doing. On the other hand, a slope 16 corresponding to the slope 15 of the case 2 is formed in the lock piece 3 inserted into the groove 10. The slope 16 of the lock piece 3 is inclined at the same angle in the same direction as the slope 15 of the case 2 and is in surface contact with the slope 15 on the case 2 side. The lock piece 3 and the slopes 15 and 16 constitute a wedge mechanism 20 that increases and decreases the frictional force between the lock piece 3 and the mating member 40. By providing such a slope structure for the wedge mechanism 20, a slide lock for locking the lowering of the case 2 as described later can be performed.

  The wedge mechanism 20 operates as follows. When a downward force (force in the direction of arrow T in FIG. 5) is applied to the case 2, the slope 15 of the case 2 slides in the T direction relative to the slope 16 (that is, the lock piece 3), thereby locking. The piece 3 is pressed in the direction of the mating member 40. As the lock piece 3 is pressed, a wedge action (action in the direction of arrow L in FIG. 5) that the lock piece 3 bites into the mating member 40 occurs, so that the frictional force between the lock piece 3 and the mating member 40 increases. On the other hand, when a rising force (force in the direction of arrow S in FIG. 5) acts on the case 2, the slope 15 of the case slides in the S direction relative to the slope 16 (that is, the lock piece 3), As a result, the lock piece 3 has a wedge action (an action in the direction of arrow F in FIG. 5) that escapes from the slope 15 of the case 2, so that the frictional force between the lock piece 3 and the mating member 4 is reduced.

  In the first case body 2a, an oblique lock guide long hole 11 parallel to the inclined surface 15 is formed (see FIG. 3). The lock guide long hole 11 penetrates a connecting pin 4 which will be described later, and the connecting pin 4 is movable in the lock guide long hole 11. Such movement of the connecting pin 4 in the lock guide long hole 11 is performed when the lock piece 3 slides relatively on the slope 15 of the case 12 as described later.

  As shown in FIGS. 4 and 6, the lock piece 3 is formed with a contact surface 31 facing the mating member 40 and contacting the outer surface of the member 40 on the front side. The contact surface 31 is a curved surface having the same curvature as the outer shape of the mating member 10, and the entire surface is in surface contact with the mating member 40. The back surface of the lock piece 3 corresponds to the slope 15 of the groove 10 in the case 2, and the entire back surface is the slope 16 described above. The lock piece 3 is formed with a pin hole 3c through which the connection pin 4 passes, and the connection between the lock piece 3 and the connection pin 4 is performed when the connection pin 4 passes through the pin hole 3c. It has become.

  The elastic body 6 made of a coil spring is attached to the first case body 2a side where the lock piece 3 is disposed. In order to attach the elastic body 6, an accommodation groove 14 is formed in the first case body 2a (see FIGS. 4 and 5). The housing groove 14 is not a through-hole penetrating the first case body 1a. Therefore, the elastic body 6 inserted into the housing groove 14 does not come into contact with the mating member 40, and the elastic body 6 The biasing force does not act as a direct frictional force against the mating member 40.

  As shown in FIGS. 4 and 7, the operation lever 5 is formed in a U-shape when viewed from above, and has a central operation portion 5a and a pair of legs extending from both ends of the operation portion 5a to the case 2 side. 5b. The operation lever 5 is attached by inserting a pair of legs 5b into the first case body 2a from the lateral direction. In order to accommodate the inserted leg portion 5b, a laterally extending recess 2c is formed on the outer surface of the first case body 2a (see FIG. 2), and the operation lever 5 is inserted into the recess 2c. As a result, the slide of the operation lever 5 is guided to the case 2.

  One end side (right end side in FIG. 4) of the pair of leg portions 5b of the operation lever 5 extends to a position corresponding to the lock piece 3, and the above-described connecting pin 4 is attached to the end portion. The connecting pin 4 constitutes a part of the operation lever 5, passes through the lock piece 3, and is stretched over the extended end of the operation lever 5 in this through state. Further, the operation portion 5 a of the operation lever 5 is in contact with the end portion of the elastic body 6 attached in a compressed state in the first case body 2 a, and the operation lever 5 is in the case by the urging force of the elastic body 6. It is biased away from 2. The operating lever 5 having such a structure connects the elastic body 6 and the lock piece 3 and acts to transmit the urging force of the elastic body 6 to the lock piece 3 by this connection. Further, as will be described later, when a pressing operation is performed on the operating portion 5 a of the operating lever 5, this pressing force is transmitted to the lock piece 3 via the connecting pin 4.

  That is, when the pressing force by the pressing operation on the operation lever 5 is transmitted to the lock piece 3 via the connecting pin 4, the lock piece 3 moves downward along the slope 15 of the case 2 (in the direction of arrow F in FIG. 5). The lock piece 3 moves away from the mating member 40 by this slide. In order to move the lock piece 3 away from the mating member 40, a pair of leg portions 5b is formed with a lock release guide slot 13 (see FIGS. 3 and 7), and the lock release guide slot 13 is connected to the connecting pin 4. Has been inserted. As shown in FIG. 3, the lock release guide long hole 13 is inclined in a direction intersecting with the lock guide long hole 11 formed in the case 2. When the operation portion 5a is pressed, the unlocking guide long hole 13 moves integrally in the pressing direction, so that the connecting pin 4 moves along the unlocking guide long hole 13, and the lock piece 3 is moved by this movement. The slope 15 of the case 2 is slid and moved away from the counterpart member 40.

  As shown in FIGS. 4 and 5, in this embodiment, the wedge mechanism 20, the elastic body 6, and the operation lever 5 including the lock piece 3 and the slope 15 are all disposed in the first case body 2 a. The wedge mechanism 20, the elastic body 6, and the operation lever 5 are members related to the locking operation of the mating member 40 at a fixed position and the lifting / lowering operation of the mating member. The second case 2b is abutted against the first case body 2a, and the pair of case bodies 2a and 2b are fastened by fastening members (not shown) such as screws. Thus, the slide lock device 1 can be easily assembled. Further, the slide lock device 1 can be disassembled by removing the fastening member. With such a divided structure, not only can the maintenance and repair of the slide lock device 1 be easily performed, but also the assembly to the mating member 40 such as a shower or a desk lamp that is in an existing installation state, That is, the slide lock device 1 can be retrofitted and versatile.

  Next, the operation of the first embodiment will be described with reference to FIGS. In the normal state, the lock piece 3 is in contact with the mating member by the slope 15 of the case 2. At this time, since the urging force of the elastic body 6 is transmitted to the lock piece 3 via the operation lever 5, a frictional force is generated between the lock piece 3 and the counterpart member 40. As a result, the case 2 is stopped at a fixed position locked by the frictional force.

  In such a state, slipping force or downward moving force is applied to the case 2 due to the entry of shampoo or hot water, an increase in the weight of the lamp, or the necessity of moving the shower head or the lamp holding head to a low position. When T (see FIG. 5) acts, the lock piece 3 tries to stop at that position, so that the lock piece 3 relatively moves on the slope 15 of the case 2 in the direction of arrow L. Thereby, the lock | rock piece 3 bites into the other party member 40, and the frictional force with the other party member 40 increases. Due to the increase of the frictional force, that is, the wedge action, the case 2 does not slide from the counterpart member 40, and the shower head and the lamp holding head do not descend. When the lock piece 3 is moved relative to the inclined surface 15, the connecting pin 4 moves through the lock guide long hole 11, so that the lock piece 3 can move stably.

  In this embodiment, when the position of the shower head is adjusted to be high, it is not necessary to forcibly operate the operation lever 5. That is, when a lifting force is applied directly to the case 2 without pressing the operating lever 5, in this rising direction S (see FIG. 5), the lock piece 3 is moved to the case 2 as shown by the arrow F direction. The lock piece 3 is somewhat separated from the mating member 40 in order to slide downward on the inclined surface 15. For this reason, the frictional force by the wedge mechanism 20 between the lock piece 3 and the counterpart member 40 is reduced. Therefore, the case 2 can be easily raised by applying a rising force that overcomes this small frictional force. In this way, the operability is improved because it is not necessary to operate the operation lever 5.

  On the other hand, when the operating lever 5 is pressed and the lever 5 is pushed in, the lock release guide slot 13 of the leg 5b pushes the connecting pin 4 diagonally downward, so that the lock piece 3 connected to the connecting pin 4 is The lock piece 3 is moved downward in the direction away from the mating member 40 by sliding down the arrow F in FIG. 5 along the slope 15 of the case 2. For this reason, the frictional force by the wedge mechanism 20 disappears or becomes extremely small. In such a state, since the locked state of the wedge mechanism is released, the case 2 can be moved with a light force in any direction. Therefore, the height of the case 2 can be adjusted smoothly and easily. When the pressing operation to the operation lever 5 is released, the wedge mechanism 20 acts on the basis of the urging force of the elastic body 6 as described above, and the lock piece 3 exerts a frictional force with the counterpart member 40. In order to generate, the case 2 can stop at that position without slipping.

  In the first embodiment as described above, the case is caused by the wedge action in which the urging force of the elastic body 6 is applied to the wedge mechanism 20 and the friction force is generated between the lock piece 3 of the wedge mechanism 20 and the counterpart member 40. Since the locking of 2 is performed, the locking force of the case 2 is increased, and the case 2 can be firmly locked to the mating member 40. Therefore, the case 2 does not descend inadvertently. Further, it is not necessary to increase the operating force due to increasing the locking force, or to use the elastic body 6 having a large biasing force in order to increase the locking force, and the operability is improved. In addition, the height can be easily adjusted, and further, the projection amount is not increased, and a compact and good design can be obtained. It is also possible to incline the slopes 15 and 16 in the direction opposite to that shown in the figure, that is, to incline so as to approach the mating member 40 from the upper side to the lower side. It becomes possible to perform a slide lock on the.

  8 to 13 show a slide lock device 1B according to a second embodiment of the present invention. FIG. 8 is a plan view of the whole, FIG. 9 is a front view, and FIG. 10 is a sectional view of a second case body 2b. 11 is a lock piece, FIG. 12 is a transverse sectional view, and FIG. 13 is a longitudinal sectional view showing the operation.

  Also in this embodiment, the case 2 is formed by a pair of case bodies 2a and 2b that can be divided, and the through-passage 7 is formed by assembling the first case body 2a and the second case body 2b. The mating member 40 passes through the through path 7. Moreover, in this embodiment, the wedge mechanism 20 is arrange | positioned at the 2nd case body 2b, and the elastic body 6 is arrange | positioned at the 1st case body 2a. That is, the wedge mechanism 20 and the elastic body 6 are arranged on both sides of the counterpart member 40. On the other hand, the operation lever 5 is attached to the case 2 so as to be spanned between the first case body 2a and the second case body 2b, whereby the operation lever 5 is disposed so as to straddle the counterpart member 40.

  Since the wedge mechanism 20 is arranged on the second case body 2b, the second case body 2b is formed with a groove 10 for arranging the lock piece 3, as shown in FIG. A slope 15 on which 3 slides relatively is formed on the side surface of the groove 10. The second case body 2b is formed with a lock guide long hole 11 into which the connecting pin 4 is inserted in an oblique direction.

  As shown in FIGS. 11 and 12, the lock piece 3 is formed in a U shape when viewed from above, so that the two leg pieces 3b are perpendicular to the opposite member 40 side from both ends of the central connecting piece 3a. It extends in a shape. The connecting piece 3a corresponds to the inclined surface 15 of the groove portion 10 in the case 2, and the back surface of the connecting piece 3a is inclined at the same angle and in the same direction as the inclined surface 15 of the case so as to be in contact with the inclined surface 15. . In this embodiment, the front surface (the surface on the mating member 40 side) of each leg piece 3b of the lock piece 3 is provided with a continuous unevenness 21 so that the front surface of the leg piece 3b bites into the mating member 40. It is like that. By performing such uneven processing 21, the lock piece 3 and the mating member 40 can be in good and reliable contact, and the strength of the frictional force between them can be adjusted.

  As shown in FIG. 12, the operating lever 5 has a pair of leg portions 5b extending to the second case body 2b, and a connecting pin 4 penetrating the lock piece 3 at the extended end of the pair of leg portions 5b. It is being handed over. Thereby, the lock piece 3 and the operation lever 5 are connected. The pair of legs 5b is formed with an unlock guide long hole 13 into which the connecting pin 4 is inserted. The lock release guide long hole 13 is inclined in a direction opposite to the lock guide long hole 11 in the second case body 2b. On the other hand, the elastic body 6 is attached in the accommodation groove 14 of the first case body 2 a in a compressed state, and an end thereof is in contact with the operation portion 5 a of the operation lever 5. With such a structure, the urging force of the elastic body 6 is transmitted to the lock piece 3 via the leg portion 5 b and the connecting pin 4. Further, by pressing the operating lever 5, the lock piece 3 can be slid away from the mating member 40 in a direction in which the frictional force decreases.

  This embodiment is different from the first embodiment in that the wedge mechanism 20 including the lock piece 3 and the slope 15 is disposed in the second case body 2b, and the elastic body 6 is disposed in the first case body 2a. The operation and action are the same as those of the first embodiment. For this reason, the arrows S, T, L, and F indicating the operation and action in FIG.

  14 and 15 show a slide lock device 1C according to a third embodiment of the present invention. In this embodiment, the lock piece 3 is arranged not only on the second case body 2b but also on the first case body 2a. The two lock pieces 3 are arranged at opposing positions in the case 2, and the connection pin 4 of the operation lever 5 passes through each lock piece 3. Further, the surface of the leg piece 3b of each lock piece 3 facing the mating member 40 is provided with a concavo-convex process 21. In addition, as the lock | rock piece 3, you may use the thing of the surface contact structure similar to the lock | rock piece 3 shown in 1st Embodiment.

  The two lock pieces 3 are set inside the groove portions 10 formed in the respective case bodies 2a and 2b. The groove portions 10 of the case bodies 2a and 2b are provided in the same manner as in the first and second embodiments. An inclined surface 15 is formed so as to correspond. In addition, a slope 16 similar to the slope 15 is formed on the back of each lock piece 3, whereby each of the two lock pieces 3 and the corresponding slope 15 constitutes a wedge mechanism 20. . In the configuration in which the two wedge mechanisms 20 are provided in this manner, the frictional force due to the wedge action is doubled, so that the locking force of the case 2 is increased, and slipping can be more reliably prevented. In order to correspond to the two lock pieces 3, two unlocking guide long holes 13 are formed in the operation lever 5. Similarly, the first case body 2a and the second case body 2b are formed with lock guide long holes 11 corresponding to the lock pieces 3, respectively.

  In this embodiment, the urging force of the elastic body 6 is transmitted to the two lock pieces 3 via the operation lever 5, whereby a frictional force is generated between the two lock pieces 3 and the mating member 40. For this reason, the case 2 can be more firmly locked. In such a structure, the urging force of the elastic body 6 can be further reduced. The height of the case 2 is adjusted only by operating the operation lever 5 and is the same as that in the first and second embodiments described above.

  FIGS. 16-19 shows the modification of the lock | rock piece 3, respectively, and can be applied to each embodiment mentioned above. In the lock piece 3 shown in FIG. 16, the uneven surface 22 in the lateral direction is provided on the contact surface 31 that contacts the mating member 40. In the lock piece 3 shown in FIG. 17, the contact surface 31 that comes into contact with the mating member 40 is provided with a concavo-convex process 23 composed of a knurling that intersects obliquely. In the lock piece 3 shown in FIG. 18, the uneven surface 24 in the vertical direction is provided on the contact surface 31 that contacts the mating member 40.

  In the lock piece 3 shown in FIG. 19, the friction member 27 is attached to the front surface portion of the circular contact surface that contacts the mating member 40. As the friction member 27, rubber or plastic having elasticity can be used, and it can be fixed to the contact surface by adhesion, welding, or other means.

    In FIG. 20, a friction member 28 is provided on the contact surface of the case 2 (in the illustrated example, the first case body 2a) that contacts the mating member 40. As the friction member 28, a member similar to the friction member 27 of FIG. 18 and the same attachment can be performed. Further, in place of the friction member 28, the outer surface of the mating member 40 may be subjected to uneven processing. The uneven processing and friction member described above may be provided on the outer surface of the mating member 40, or may be provided on both the case 2 and the mating member 40.
