Accordingly, the upper cap prevents rainwater or dust from flowing into the upper part of the cylinder 63 . Since such an upper cap can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

Meanwhile, the aforementioned cylinder 63 may have an elastic body 62 , one side member PT and a lifting member RD built therein, as shown in FIG. 8 . As shown, the elastic body 62 is composed of a coil spring and is built into the cylinder 63, and is prevented from being separated by the lower cap (CP). The one side member PT is provided on one side of the elastic body 62 for expansion and contraction of the elastic body 62 as shown. One side member (P), for example, may be provided on the upper portion of the elastic body 62 as shown and installed on one side of the elastic body (62). As shown in the figure, the one-side member PT may be formed of a plate or a horizontal bar having a diameter or a length greater than that of the elastic body 62 .

The lifting member RD is connected to one side member PT at one end as shown, and the stick 65 of the handle is connected to the other end. The elevating member RD may be configured as, for example, a rod-shaped rod as shown. As shown in the figure, the lifting member RD may include a ring ER to which the biner BN is coupled. As shown in the figure, as the binner BN connected to the ring ER at the lower end of the lifting member RD is fastened to the ring R provided on the stick 65 of the handle, the stick 65 of the handle is located at the lower portion. connected as one However, the lifting member RD may be directly connected to the stick 65 of the handle at the lower end by welding or bolting, unlike shown.

As shown in FIG. 8, when the user pulls the stick 65 of the handle downward, the lifting member RD descends together with the one side member PT as shown in FIG. As shown in the enlarged view, it descends in the vertical direction. At this time, the one side member PT is compressed by pressing the elastic body 62 from the top. And, when the user's force pulling the stick 65 is weakened or lost and the elastic body 62 is restored, the one side member PT rises back to the original position together with the elevating member RD as shown enlarged in FIG. 8 . do. Accordingly, the user who has pulled the stick 65 downward is stretched while both hands and arms are pulled upward as the stick 65 rises by the lifting member RD. Accordingly, the user's muscles are smoothly relaxed and contracted by the elastic force provided while the elastic body 62 is stretched and contracted, so that the exercise effect is doubled. At this time, as the elastic body 62 is built into the cylinder 63, noise is blocked. As a result, the user's muscles are smoothly contracted and relaxed by the elastic force, so the muscle strength is strengthened.

On the other hand, the muscle strengthening exercise device 50 according to the embodiment of the present invention as described above may be installed on the hanger as shown in FIGS. 9 and 10 . These hangers are a pair of base frames 120 installed in a spaced apart state on the floor, a pair of posts 110 installed vertically on the base frame 120, respectively, in a horizontal state between the posts 110, as shown. It may include a space bar 110b installed to prevent the posts 110 from being opened or closed, and a plurality of hooks 112 installed on the posts 110 along the longitudinal direction of the posts 110 .

The area of the base frame 120 increases toward the rear as shown in FIG. 9 so that the post 110 does not fall backward by the user's weight when the user uses it. As the area of the base frame 120 increases toward the rear, the weight of the rear is heavier than that of the front. Accordingly, the base frame 120 is prevented from passing backward.

The post 110 is installed in the base frame 120 through the fitting pipe 110a installed in the base frame 120 as shown in FIGS. 9 and 10 so as to be separated from the base frame 120 . desirable. The post 110 may be installed vertically on the upper portion of the base frame 120 as shown by an imaginary line in FIG. It may be installed to be inclined at an inclination of 25 degrees. As shown by the imaginary line and the solid line, the post 110 has the hook 112 vertically aligned or not vertically aligned depending on the installation angle. The installation angle of the post 110 is determined according to the installation conditions of the muscle strengthening exercise device 50 .

The hook 112 is fixed by hooking the cross bar 90 as shown in FIG. 10 . The crossbar 90 may be installed on the hook 112 of a desired height since the hook 112 is installed along the longitudinal direction of the post 110 . The crossbar 90 is installed in a horizontal state on the post 110 by the hook 112 as shown. As shown in the crossbar 90, the muscle strengthening exercise device 50 is fixed through the above-described fixing unit.

Here, the above-described hook 112 may be attached to the post 110 by welding or bolting after being manufactured by punching a metal plate with a laser, as shown in enlarged view in FIG. 9 . Therefore, the hook 112 can be easily manufactured.

On the other hand, the above-mentioned fixing part may be configured as a sleeve 57 as shown in FIGS. 11 and 12 . As shown, the sleeve 57 has an inner diameter greater than the outer diameter of the crossbar 90 . The sleeve 57 is fitted in a horizontal state to the crossbar 90 as shown and is rotatably integrally fixed to the crossbar 90 . As shown in the figure, the sleeve 57 may be vertically connected to the connecting portion of FIG. 8 . The sleeve 57 is preferably connected to the connecting portion of FIG. 8 in a communication state as shown so that the overall weight is reduced.

As shown in FIG. 12 , the sleeve 57 may have a bearing 57a installed on its inner circumferential surface. The bearing 57a is composed of a circular ball bearing as shown, and the cross bar 90 passes through the center thereof. The bearing 57a reduces friction of the sleeve 57 against the crossbar 90 when the sleeve 57 is rotated about the crossbar 90 by the user. Accordingly, the sleeve 57 rotates smoothly.

The bearing 57a is integrally fixed to the inner circumferential surface of the sleeve 57 by a bearing fitting. The bearing fitting supports the side surface of the bearing 57a to removably fix the bearing 57a to the inner circumferential surface of the sleeve 57 . As shown in FIG. 12, the bearing fitting is installed on the inner circumferential surface of the stepped 57p and the sleeve 57 protruding from the inner circumferential surface of the sleeve 57 to support one side of the bearing 57a, and the other side of the bearing 57a. It can be configured with a supporting snap ring (SR). In this case, since both sides of the bearing 57a are supported by the stepped 57p and the snap ring SR, it is firmly fixed to the inner circumferential surface of the sleeve 57 . However, the bearing fitting may be configured to support both sides of the bearing 57a by configuring the aforementioned snap rings SR as a pair. That is, the snap rings SR may be fixed to the inner circumferential surface of the sleeve 57 so as to be positioned on both sides of the bearing 57a, and thus support both sides of the bearing 57a. The configuration of these snap rings (SR) is easy to understand by those skilled in the art, so a detailed description thereof will be omitted.

The sleeve 57 may have a waterproof cover 57b installed at an end thereof as shown in FIG. 12 . The waterproof cover 57b is installed on the outside of the bearing 57a as shown to shield the outside of the bearing 57a. The waterproof cover 57b may be formed of, for example, a rubber plate or a rubber stopper. The waterproof cover 57b is fixed to the sleeve 57 in a detachable state by a cover fitting. The cover fitting is installed on the inner circumferential surface of the sleeve 57 as shown and may be configured as a snap ring SR for supporting the surface of the waterproof cover 57b along the rim of the waterproof cover 57b. Since the snap ring SR is the same as the snap ring SR of the aforementioned bearing fitting, a detailed description thereof will be omitted.

Meanwhile, the aforementioned lower cap CP may be provided with a spring seat SP as shown in FIG. 12 . The spring seat SP is formed to protrude from the lower cap CP as shown to support the outer peripheral surface of the aforementioned elastic body 62 . The spring sheet SP supports the elastic body 62 as it is in close contact with the outer circumferential surface of the elastic body 62 as shown. Accordingly, the elastic body 62 is prevented from flowing during expansion and contraction, and thus collision with the inner circumferential surface of the sleeve 57 is prevented, so that no collision noise is generated.

As shown in FIG. 13 , the muscle strengthening exercise device 50 as described above is installed by inserting the sleeve 57 into the crossbar 90 installed horizontally on the post 110 of the hanger. Accordingly, the user can exercise while holding the handle on the lower side of the cylinder 63 vertically connected to the sleeve 57 . At this time, the sleeve 57 rotates smoothly by the internal bearing 57a, and is waterproofed by the waterproof cover 57b, so that it operates smoothly outdoors. Since the elastic body 62 is supported by the spring seat SP, the elastic body Not only does the 62 stably expand and contract, but also noise caused by the elastic body 62 is prevented.

Here, the above-mentioned post 110 is vertically installed on the ground as the flange at the bottom is bolted with a bolt (B) to the foundation (BS) buried in the ground as shown in FIG. 13 . In addition, both ends of the above-described crossbar 90 are fixed to the post 110 by bolts B as enlarged in FIG. 13 . The crossbar 90 is provided with a snap ring SR caught on the bearing 57a of the sleeve 57 as shown in FIG. 14 . The snap ring SR is installed in the snap ring groove 90a formed in the crossbar 90 as shown in an enlarged view, and is supported by the bearing 57a to prevent the sleeve 57 from flowing as it is caught. Therefore, the muscle strengthening exercise device 50 does not move along the crossbar 90 during exercise.

On the other hand, the aforementioned crossbar 90 or post 110 may be provided with a stopper. This stopper prevents the sleeve 63 or the clamp 55 or the hook 52 of the fixing part rotatably installed on the crossbar 90 from rotating 360 degrees around the crossbar 90 as described above. is a component that That is, the stopper prevents the muscle strengthening exercise device 50 from being rotated by 360 degrees around the crossbar 90 . Therefore, the stopper prevents the muscle strengthening exercise device 50 from rotating 360 degrees to collide with the user's occipital region.

The stopper is, for example, as shown in enlarged view in FIG. 13, protruding from the crossbar 90 in a bent state, and controlling the rotation angle of the fixing part as the fixing part or the connecting part is caught through the protruding part; can be configured as Contrary to this, for example, as shown in FIG. 13, the stopper is fixed to the upper part of the post 110 and installed at a higher position than the crossbar 90, and is a panel that controls the rotation angle of the fixing part as the fixing part or the connecting part is caught. It may be composed of a configured barricade 95 . These bending sticks 92 or the barricades 95 are caught by the sleeve 63 when the muscle strengthening exercise device 50 rotates. Therefore, the bending stick 92 or the barricade 95 controls the rotation angle of the muscle strengthening exercise device 50 to prevent the occurrence of a safety accident.

Here, the above-described barricade 95 may be configured as a rod installed at the upper end of the post 110 like the crossbar 90 , unlike the illustrated one. These rods are installed on the upper end of the crossbar 90 to control the rotation angle of the muscle strengthening exercise device 50 as the cylinder 63 is caught. Since such a rod is a technology that can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

On the other hand, the above-described fixing unit may be configured as a horizontal bar 58 as shown in FIGS. 15 and 16 . That is, the fixing part may be provided with a horizontal bar 58 formed of a tubular member as shown, and may include a bearing 58a and a side cover 59 . At this time, the bearing 58a and the side cover 59 are each composed of a pair of elements and may be respectively installed on both sides of the horizontal stand 58 .

Here, the horizontal bar 58 may be formed of a tubular member having an inner diameter greater than the outer diameter of the crossbar 90 as shown in FIGS. 15 and 16 . For example, the horizontal bar 58 may be formed of a cylindrical metal tube. The horizontal bar 58 may be fitted to the crossbar 90 in a horizontal state to be rotatably fixed to the crossbar 90 integrally. The horizontal bar 58 may be vertically connected to the above-mentioned connecting portion in the middle portion. And, the horizontal bar 58 may be formed with a fastening groove (FH) for coupling with the side cover 59 to be described later. The fastening grooves FH may be spaced apart along the circumferential direction on the end surface of the horizontal bar 58, which is a tubular member, and formed in the shape of a plurality of grooves inserted in the longitudinal direction. For example, the fastening groove FH may be configured in the shape of four grooves, and the side cover 59 may be coupled through four fastening members (not shown). The horizontal bar 58 may have a bearing 58a installed on its inner circumferential surface.

The bearing 58a may be installed on the inner circumferential surface of the horizontal bar 58 as shown. The bearing 58a may be configured as a circular ball bearing, and the cross bar 90 is installed through the center thereof. The bearing 58a reduces friction of the horizontal bar 58 with respect to the crossbar 90 when the horizontal bar 58 is rotated about the crossbar 90 by the user. Accordingly, the horizontal bar 58 is smoothly rotated.

The bearing 58a may be integrally fixed to the inner circumferential surface of the horizontal bar 58 by a bearing fitting.

The bearing fitting supports the side surface of the bearing 58a and detachably fixes the bearing 58a to the inner circumferential surface of the horizontal bar 58 . As shown in FIG. 16 , the bearing fitting is provided on the inner circumferential surface of the horizontal bar 58 to support one side of the bearing 58a and is installed on the inner circumferential surface of the fixed jaw 58b and the horizontal bar 58 of the bearing 58a. It may include a fitting ring (58c) for supporting the other side.

The fixing jaw 58b may be integrally formed to protrude from the inner circumferential surface of the horizontal bar 58 . That is, the fixed jaw 58b may be formed as a protrusion or concave portion that provides a step-shaped jaw on the inner circumferential surface of the horizontal stand 58, which is a tubular member, and one side of the bearing 58a inserted into the horizontal stand 58. can support That is, the fixed jaw 58b may be configured to fix the bearing 58a to limit the flow of the bearing 58a in one direction.

The fitting ring 58c may be installed in the snap ring groove 90a formed in the crossbar 90, As it is caught to support the bearing 58a, it is possible to restrict the flow in the other direction of the bearing 58a. Here, the fitting ring 58c may be located on the outer portion rather than the inner portion of the bearing 58a, unlike the snap ring SR shown in FIG. 12 or FIG. 14 to support the other side of the bearing 58a.

As such, since the bearing fitting can directly support both sides of the bearing 58a through the fixing jaws 58b and the fitting ring 58c, flow and separation of the bearing 58a in both directions can be prevented.

The side cover 59 may be installed on the outside of the bearing 58a as shown to shield the outside of the bearing 58a and shield the open part of the horizontal bar 58 . The side cover 59 may be composed of, for example, a rubber plate or a rubber stopper. The side cover 59 may be configured to include a bolt groove (BH) formed to correspond to the fastening groove (FH) of the horizontal stand (58), and the fastening member (not shown) is connected through the bolt groove (BH). As it is fastened to the fastening groove FH, it may be firmly fixed to the horizontal bar 58 . That is, since the side cover 59 is directly connected and fixed to the horizontal table 58 , it can be rotated together with the horizontal table 58 , and is prevented from being separated by the rotation operation. In particular, unlike the waterproof cover 57b shown in FIG. 12 or 14 that the side cover 59 is coupled to the sleeve 57 by a snap ring (SR) fitted to the outside, it is fixed in a direct connection method, so stable fixing is not possible. has the advantage of being able to

At this time, the side cover 59 allows the head of the fastening member to be positioned inside the body of the side cover 59 as the bolt groove BH is formed to a predetermined depth, so that the fastening member is directly exposed to the outside. can be prevented In addition, a protrusion 59a may be provided on the side cover 59 .

The protrusion 59a may be formed to protrude in a cylindrical shape having an outer diameter corresponding to the inner diameter of the horizontal bar 58, and is inserted into the pipe portion of the horizontal bar 58 to maintain close contact with the horizontal bar 58. can keep In addition, the protrusion 59a may be disposed such that the protruding surface is in contact with the bearing 58a located inside the horizontal bar 58 , and may press and support the surface of the bearing 58a from the side. Accordingly, the side cover 59 restricts the flow of the bearing 58a through the protrusion 59a, and can prevent the bearing 58a from being separated to the outside.

In addition, the side cover 59 may include an inner mouth (59b) formed on the end side of the protrusion (59a). The inner mouth (59b) may be formed to correspond to the shape of the outer circumferential surface of the fitting ring (58c) at the end of the protrusion (59a). This inner groove 59b supports the bearing 58a and the fitting ring 58c by the side cover 59 so that the protrusion 59a can contact the bearing 58a and the fitting ring 58c at the same time.

Alternatively, the side cover 59 may be installed in the same structure as the structure in which the waterproof cover 57b shown in FIG. 12 or 14 is installed, for example, both sides of the horizontal stand 58 open in a restrained state by a snap ring. can be installed in the department.

As shown in FIGS. 15 and 16 , the muscle strengthening exercise device 50 as described above is installed by inserting a horizontal bar 58 into the crossbar 90 installed in a horizontal state. Accordingly, the user can exercise by holding the handle on the lower side of the connection part vertically connected to the horizontal bar 58 . At this time, the horizontal bar 58 rotates smoothly by the inner bearing 58a, the separation of the bearing 58a is prevented by the side cover 59 and shielded from the outside, so that it can be smoothly operated outdoors. .

In addition, as the side cover 59 is installed at the end of the horizontal bar 58 through bolting, it is possible to block rainwater or foreign substances from entering the inside of the horizontal bar 58, and is directly connected and fixed by bolting. Accordingly, it can be stably fixed, and it can be prevented from being separated by the rotationally operated horizontal bar 58 .

On the other hand, as shown in FIGS. 15 and 16 , the above-described connection part may be configured as a hollow vertical bar 64 . That is, the connecting portion may be provided as a vertical stand 64 connected to the upper portion of the fixing portion composed of the horizontal bar 58 as shown, and may be configured to include a lower cover 64a.

Here, the vertical stand 64 may be formed of a cylindrical metal tube as shown. That is, the vertical bar 64 may be formed of a tubular member integrally connected to the lower portion of the horizontal bar 58 . As shown in FIG. 15 , a seating surface SF having a curvature corresponding to the outer diameter of the horizontal bar 58 may be provided on the vertical bar 64 to be coupled to the horizontal bar 58 as shown in FIG. 15 . The vertical bar 64 is welded to the lower part of the horizontal bar 58 through the seating surface SF, so that the open upper part is shielded. At this time, the vertical bar 64 is preferably connected in a communication state so that the overall weight is reduced.

This vertical stand 64 may include a lower cover 64a. At this time, the vertical stand 64 may be formed with a fastening groove (FH) for coupling with the lower cover (64a) to be described later. The fastening groove (FH) may be provided in the shape of a plurality of grooves spaced apart along the circumferential direction on the lower end surface of the vertical stand 58, which is a tubular member, and inserted in the longitudinal direction. As for the vertical stand 64, the lower cover 64a may be fixed to the lower end while the fastening member (not shown) is coupled to the fastening groove FH.

The lower cover 64a is connected to the lower side of the aforementioned handle. The handle may be connected to the lower cover 64a through a conventional binner (BN) as shown and a connection ring (CR) to be described later. That is, the stick 56 of the handle may be integrally connected to the vertical stand 64 through the binner BN and the connecting ring CR. Accordingly, the handle may be installed in a horizontal state under the vertical stand 64 on which the lower cover 64a is mounted.

As described above, the muscle strengthening exercise device 50 has superior durability than the band 54 described above because the vertical stand 64 is made of a hollow metal tube, and it is possible to prevent the weight from being increased through the hollow, The handle may be connected through the lower cover 64a.

In particular, since the muscle strength strengthening exercise device 50 according to this embodiment is fixed by welding with the horizontal bar 58 supported by the vertical stand 64 by the seating surface SF formed on the vertical stand 64, Welding can be easily performed during bonding, and stable fixing is possible.

In addition, the above-described connection portion may include a stretching means 66 as shown in FIG. That is, the extension means 66 may be built in the vertical stand 64 . The stretching means 66 may include an elastic member 66a, a pressing member 66b and a moving member 66c as shown in the drawing.

As shown in the figure, the elastic member 66a is formed of a coil spring and is embedded in the vertical stand 64 , and separation can be prevented by the lower cover 64a. That is, the elastic member 66a is built into the vertical stand 64 as shown for noise blocking and safety and is shielded by the lower cover 64a. The elastic member 66a may provide a repulsive force through the expansion and contraction action by the pressing member 66b and the moving member 66c, which will be described later. As a result, the elastic member 66a provides elasticity while expanding and contracting when the handle is moved up and down by the user. Accordingly, the user relaxes and contracts the muscles by the elasticity of the elastic member 66a provided in the elastic member 66 during exercise, so that the exercise effect is doubled.

Here, the surface of the elastic member 66a may be coated. That is, a coating portion (not shown) may be provided on the outer surface of the elastic member 66a, and the coating portion may be applied as a rubber coating or the like. Accordingly, the elastic member 66a is prevented from rusting by the coating portion and has abrasion resistance, and noise generation due to impact or the like can be minimized.

The pressing member 66b may be provided so as to be in contact with one side of the elastic member 66a for expansion and contraction of the elastic member 66a. The pressing member 66b may be provided on an upper portion of the elastic member 66a as shown, and may be movably installed on one side of the elastic member 66a. The pressing member 66b may be formed of a plate material having a larger diameter or length than that of the elastic member 66a. The pressing member 66b can press the elastic member 66a while being connected to a moving member 66c to be described below and moving together with the moving member 66c.

And, as shown, the pressing member 66b may include an upper support portion UC for supporting the outer peripheral surface of the above-described elastic member 66a. The upper support portion UC may be provided to protrude downward from the periphery of the pressing member 66b. Accordingly, the pressing member 66b may be disposed to partially surround the upper outer circumferential surface of the elastic member 66a as the upper support part UC protrudes and is formed as a cap-shaped member, and the upper spring sheet for the elastic member 66a can act as That is, the pressing member 66b may be disposed in the form of a cap covered on the upper portion of the elastic member 66a by the upper support portion UC, and may prevent the elastic member 66a from flowing and separated.

The pressing member 66b may be made of a non-metallic synthetic resin material to minimize noise caused by friction with the elastic member 66a, which is a metal or plastic material, and to provide a stable support action for the elastic member 66a, an example As a monomer cast nylon (Mono Cast Nylon, M/C) may be composed. In addition to this, the pressing member 66b may be made of any one of a general rubber material or an engineering plastic material.

The moving member 66c may have one end connected to the pressing member 66b and a handle connected to the other end thereof. For example, the moving member 66c may be formed as a rod-shaped rod as shown. In this case, the moving member 66c may be a cylindrical member having a larger diameter than the bolt diameter of the connecting ring CR, which will be described later, thereby ensuring rigidity. The moving member 66c may be inserted through the central portion of the pressing member 66b through the fastening protrusion SJ formed thereon.

Here, the cylindrical fastening protrusion SJ of the moving member 66c has a smaller diameter than the diameter of the rod body and is formed to protrude from the upper end of the moving member 66c, so that the pressing member 66b is seated on the upper side. is connected and the fastening protrusion (SJ) is coupled to the pressing member (66b) to pass through. A washer (W) and a nut (NT) are coupled to the fastening protrusion (SJ) in the moving member (66c) to fix the pressing member (66b).

The movable member 66c is connected to a lower end of the handle and can be moved downward by the user's pulling force. The moving member 66c may be provided with a connecting ring CR to which the binner BN is coupled to the lower end portion, and the connecting ring CR may be formed in the form of a normal eyebolt. As shown in the figure, the moving member 66c has a bolt portion BP protruding from the connecting ring CR is inserted thereinto, and a fastening screw groove TG may be formed at the lower side. Accordingly, the connecting ring CR may be detachably coupled to the moving member 66c.

As such, as the movable member 66c and the connecting ring CR are provided in a separate configuration and have a structure to be coupled to each other, the elevating member RD integrally connected with the ring ER shown in FIG. 12 or FIG. It is possible to form the moving member 66c to have an improved diameter than the diameter, so that stability for the expansion and contraction operation can be secured, and it can be guided and entered through the hole of the lower cover 54a.

At this time, the expansion and contraction means 66 may be disposed in a state in which the circumferential side surface of the pressing member 66b and the outer circumferential surface of the upper support part UC are in contact with the inner diameter of the vertical stand 64 , in the interior of the vertical stand 64 . Since it is moved together with the moving member 66c, the stable lifting and lowering movement of the moving member 66c is guided.

The muscle strengthening exercise device 50 as described above lowers the pressing member 66b in the vertical direction while the moving member 66c descends together when the user pulls the handle downward. At this time, the pressing member (66b) presses the elastic member (66a) from the upper portion to compress. And, when the user's force pulling the handle is weakened or lost and the elastic member 66a is restored, the pressing member 66b rises back to the original position together with the moving member 66c. Accordingly, the user who has pulled the handle downward is stretched while both hands and arms are pulled upward as the handle is raised by the moving member 66c.

Accordingly, the user's muscles are smoothly relaxed and contracted by the elastic force provided while the elastic member 66a is stretched and contracted, so that the exercise effect is doubled. At this time, the moving member 66c may be stably guided and moved with respect to the user's pulling operation.

As the elastic member 66a is built into the vertical stand 64, noise is blocked. In conclusion, through the elastic means 66 that provides a repulsive force to the moving direction of the handle, the user's muscles are smoothly contracted and relaxed by the elastic force, so that the muscle strength is strengthened.

In particular, the muscle strength strengthening exercise device 50 according to the present embodiment wraps around the upper portion of the elastic member 66a as the pressing member 66b coupled to the upper portion of the elastic member 66a is provided in a cap shape rather than a disk shape. Since it is moved up and down from the inside of the vertical bar 64 while it is being moved, it is possible to stably guide the lifting operation with respect to the elastic member 66a and the moving member 66c.

On the other hand, the vertical stand 64 may further include a separation prevention cap (64b).

The separation prevention cap 64b may be installed in a state of being seated on the upper portion of the lower cover 64a to be in contact with the lower side of the elastic member 66a. The separation prevention cap 64b may be fixed by being fitted to the lower cover 64a, or may be fixed by being screwed onto the inner circumferential surface of the lower cover 64a.

At this time, the lower cover 64a may have a seating ring SR supporting the lower surface of the separation prevention cap 64b so that the separation prevention cap 64b is not exposed to the outside to protrude from the inner circumferential surface. The seating ring SR may be provided to protrude from the inner circumferential surface of the lower cover 64a and disposed to contact the outer surface of the moving member 66c. That is, as the lower cover 64a protrudes so that the seating ring SR comes into contact with the outer surface of the movable member 66c, it is possible to shield the lower portion of the vertical stand 64 .

Here, a lining sheet (FS) may be installed on the inner peripheral surface side of the seating ring (SR). The lining sheet FS may be made of a friction material, and may provide a friction force while in contact with the moving member 66c to provide a force opposing the expansion/contraction operation according to the movement of the moving member 66c. That is, the lining sheet FS limits the expansion and contraction operation of the expansion and contraction means 66 , so that the user may be guided to use a greater force than the force applied to the elastic member 66a.
