Technical Field

[0001] The utility model belongs to clothing ironing equipment, and particularly relates to a locking mechanism, a rod with adjustable length, an angle adjusting mechanism of an ironing board and a hanging ironing machine. Background Art

[0002] The utility model patent application with the publication number of CN117449077A discloses a steam hanging ironing machine with an adjustable inclination angle of an ironing board, and the utility model patent application with the publication number of CN117845594A discloses an ironing board and a hanging ironing machine with variable postures. Since the ironing board needs to be flipped to the required angle and locked and fixed at the required angle during use, a locking mechanism that is easy to operate and can be reliably locked is an essential mechanism for the ironing board. Moreover, a flipping mechanism of the ironing board with a simple structure can facilitate operation, support and fix the ironing board reliably and stably, reduce the product weight, and reduce the product manufacturing cost. The existing locking mechanism is large in size and complex in structure. Content of the Utility Model

[0003] The utility model aims to provide a locking mechanism, a rod with adjustable length, an angle adjusting mechanism of an ironing board and a hanging ironing machine, so as to achieve at least one of the purposes of reliably locking and fixing the ironing board at the required angle, facilitating the operation when adjusting the angle of the ironing board, reducing the product weight, and reducing the product manufacturing cost.

[0004] To achieve the above purpose, the locking mechanism of the utility model includes:

[0005] A first member having a lumen;

[0006] A second member, the first end of which is inserted into the lumen of the first member;

[0007] A locking assembly including a squeezing member, an expanding member, an elastic member and an unlocking member; the squeezing member is located in the lumen of the first member and is attached to the first end of the second member so that the squeezing member can move in the lumen of the first member along with the first end of the second member; the expanding member radially expands the squeezing member by the elastic force of the elastic member to directly or indirectly squeeze the squeezing member against the inner wall of the lumen to achieve locking, and the second member is prohibited from moving relative to the first member during locking; the unlocking member is connected to the expanding member, and the expanding member is actuated by the unlocking member to overcome the elastic force of the elastic member to weaken or eliminate the radial expansion of the expanding member on the squeezing member and the direct or indirect squeezing of the squeezing member against the inner wall of the lumen to achieve unlocking, and the second member is allowed to move relative to the first member during unlocking.

[0008] In this locking mechanism, the expanding member radially expands the squeezing member by the elastic force of the elastic member to directly or indirectly squeeze the squeezing member against the inner wall of the lumen. When the second member moves relative to the first member, static friction is generated to prevent the movement, so as to achieve locking and prohibit the second member from moving relative to the first member. The action is flexible and the locking is reliable.

[0009] In this locking mechanism, the locking component is hidden in the lumen of the first component, with a compact structure, small occupied space, and light product weight, which is beneficial to reducing the manufacturing cost of the product.

[0010] This locking mechanism does not need to set gears and can lock the expansion component at any position on the inner wall of the lumen, realizing stepless adjustment.

[0011] This locking mechanism realizes locking by using the elastic force of the elastic component and unlocks through the unlocking component, with convenient operation.

[0012] Preferably, the extrusion component includes extrusion petals distributed circumferentially. The expansion component is located inside the extrusion petals and cooperates with the extrusion petals through inclined surfaces. The expansion component radially expands the extrusion petals by the elastic force of the elastic component to directly or indirectly extrude the extrusion petals against the inner wall of the lumen to achieve locking. The unlocking component actuates the expansion component to overcome the elastic force of the elastic component to weaken or eliminate the radial expansion of the expansion component on the extrusion petals and the direct or indirect extrusion of the extrusion petals against the inner wall of the lumen to achieve unlocking. Since the extrusion petals have a large radial deformation ability, they can reliably extrude against the inner wall of the lumen to achieve locking and can also fully weaken or eliminate the extrusion against the inner wall of the lumen to achieve unlocking, ensuring reliable locking and unlocking and avoiding incomplete locking and unlocking caused by insufficient deformation ability of the extrusion component.

[0013] Preferably, the extrusion petals have their own elastic force. When locking, the expansion component overcomes the self-elastic force of the extrusion petals. When unlocking, the extrusion petals weaken or eliminate the direct or indirect extrusion against the inner wall of the lumen by virtue of their own elastic force. Accordingly, the unlocking action is ensured to be smooth and jamming is avoided.

[0014] Preferably, the root of the extrusion petal is made into a weak part to promote the radial elastic deformation of the extrusion petal. Accordingly, on the premise of ensuring sufficient self-elastic force of the extrusion petal, its radial elastic deformation is ensured to avoid incomplete locking and unlocking caused by insufficient deformation ability of the extrusion petal.

[0015] Preferably, a tightening component is sleeved outside the extrusion petal. When locking, it overcomes the tightening force of the tightening component. When unlocking, the extrusion petal weakens or eliminates the direct or indirect extrusion against the inner wall of the lumen by virtue of the tightening force of the tightening component. Accordingly, the unlocking action is ensured to be smooth and jamming is avoided.

[0016] Preferably, the tightening component serves as a friction component. When locking, the tightening component is extruded by the extrusion petal against the inner wall of the lumen. When unlocking, the extrusion of the tightening component against the inner wall of the lumen is weakened or eliminated. Accordingly, when locking, the friction is increased by extruding the tightening component against the inner wall of the lumen to ensure reliable locking. When unlocking, the tightening component will contact the inner wall of the lumen and generate damping as the second component moves, enabling the second component to move in a controlled manner. Moreover, the tightening component is given two functions of avoiding jamming when unlocking and increasing friction when locking, with a compact structure.

[0017] Preferably, a friction member is sleeved outside the extrusion flap. When locked, the friction member is pressed by the extrusion flap against the inner wall of the lumen; when unlocked, the extrusion of the friction member against the inner wall of the lumen is weakened or eliminated. Accordingly, when locked, the friction is increased by pressing the friction member against the inner wall of the lumen to ensure reliable locking. When unlocked, the friction member will contact the inner wall of the lumen, and a damping force is generated as the second member moves, causing the second member to move in a controlled manner.

[0018] Preferably, the friction member is in the shape of a ring sleeve, and a constraint groove is provided on the outer side of the extrusion flap, and the friction member is located in the constraint groove. This prevents the friction member from being disengaged due to friction.

[0019] Preferably, the outer surface of the extrusion flap is configured with friction features. When locked, the friction features are pressed by the extrusion flap against the inner wall of the lumen; when unlocked, the extrusion of the friction features against the inner wall of the lumen is weakened or eliminated. Accordingly, when locked, the friction is increased by pressing the friction features against the inner wall of the lumen to ensure reliable locking. When unlocked, the friction features will contact the inner wall of the lumen, and a damping force is generated as the second member moves, causing the second member to move in a controlled manner.

[0020] Preferably, the unlocking member is configured to actuate the expansion member and overcome the elastic force of the elastic member by being pulled. Accordingly, the unlocking member is easy to operate, and a steel wire rope can be used as the unlocking member, which occupies a small space.

[0021] Preferably, the unlocking member extends from the second member, resulting in a compact structure.

[0022] Preferably, a support seat is fixed to the first end of the second member, the extrusion member is connected to the support seat, the elastic member is a helical compression spring supported between the expansion member and the support seat, and the unlocking member passes through the support seat and the elastic member. The support seat not only provides support for the elastic member to generate elastic force, but also simplifies the structure and ensures the assembly strength of the extrusion member.

[0023] The locking mechanism of the present utility model is preferably applied to a rod with an adjustable length. The rod includes the locking mechanism of the present utility model. The first member and the second member form the rod. When unlocked, the length of the rod is adjusted by the relative movement of the second member with respect to the first member. When locked, the relative movement of the second member with respect to the first member is prohibited to fix the length of the rod.

[0024] Preferably, the first end of the second member is inserted into the lumen of the first member through the second end of the first member, and a bushing is provided at the second end of the first member, and the bushing is located between the outer wall of the second member and the inner wall of the first member. The bushing can not only guide the movement of the second member when unlocked without generating friction with the first member, but also support the second member to prevent the second member from shaking and ensure the stability of the rod.

[0025] Preferably, both the first member and the second member are tubular. This can save materials and reduce weight while ensuring strength.

[0026] The adjustable-length rod of the present utility model is preferably applied to the angle adjustment mechanism of the ironing board. The angle adjustment mechanism of the ironing board includes a support member and an ironing board. The ironing board is configured to flip relative to the support member, and further includes a handle and the adjustable-length rod of the present utility model. The handle is linked to an unlocking member and is configured to operate the handle to unlock the locking mechanism and release the handle to lock the locking mechanism. When the handle is operated to unlock the locking mechanism, the length of the rod changes with the flipping of the ironing board. When the handle is released to lock the locking mechanism, the length of the rod is fixed and the flipping of the ironing board is prohibited. Accordingly, the ironing board can be reliably locked and fixed at the desired angle, the operation is convenient when adjusting the angle of the ironing board, the product weight is reduced, and the product manufacturing cost is reduced.

[0027] Preferably, the handle is arranged on the back of the ironing board. A swinging member is also arranged on the back of the ironing board. The swinging member is linked to the handle and operating the handle causes the swinging member to swing. The unlocking member is connected to the swinging member. Accordingly, by manipulating the handle to drive the swinging member to swing, the unlocking member is then driven. According to the lever action of the swinging member, the moving stroke of the unlocking member can be increased as needed, and the unlocking force of the unlocking member can also be increased.

[0028] Preferably, the ironing board is rotationally assembled with the support member via a first shaft. One end of the rod is rotationally assembled with the ironing board via a second shaft, and the other end of the rod is rotationally assembled with the support member via a third shaft. The first shaft, the second shaft, and the third shaft are respectively projected onto a vertex of a triangle along their axial directions, and the rod serves as a side of the triangle. Accordingly, relying on the reliability of the triangle, the angle adjustment mechanism of the ironing board is simplified, and reliable support for the ironing board is ensured.

[0029] The angle adjustment mechanism of the ironing board of the present utility model can be applied to a hanging ironing machine. The hanging ironing machine includes a main body and an ironing terminal, and further includes the angle adjustment mechanism of the ironing board of the present utility model. Accordingly, clothes can be hung or laid flat on the ironing board, steam is generated by the main body, and the clothes are ironed with an ironing terminal such as an iron, an ironing head, etc., improving the comfort, convenience, and ironing effect of ironing.

[0047] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0048] The terms "comprising" and "having" and any variations thereof in the description and claims of the present utility model are intended to cover non-exclusive inclusion. For example, a method or product comprising a series of technical features does not necessarily limit to those clearly listed technical features, but may also include other technical features that can be included in the method or product and are not clearly listed. [[ID=2,4]]

[0049] In the description of the present utility model, it should be understood that the technical features defined by the terms with sequential concepts such as "first", "second", etc. are only for clearly describing the defined technical features, so that the defined technical features can be clearly distinguished from other technical features, rather than representing such naming in actual implementation. Therefore, it cannot be construed as a limitation to the present utility model.

[0050] The present utility model will be introduced in detail below with reference to specific embodiments and the accompanying drawings.

[0051] Figure 7 An embodiment of the locking mechanism 100 of the present utility model is shown. The illustrated locking mechanism includes a first component 110, a second component 120 and a locking assembly 130.

[0052] The first component 110 is tubular and has a lumen 111.

[0053] The second component 120 is also tubular, and the first end ( Figure 7 the lower end in) of the second component is inserted into the lumen 111 of the first component.

[0054] The locking assembly 130 includes a squeezing member 131, an expanding member 132, an elastic member 133, and an unlocking member 134. The squeezing member 131 is located in the lumen 111 of the first component and is attached to the first end of the second component 120 such that the squeezing member can move with the first end of the second component in the lumen of the first component. The expanding member 132 radially expands the squeezing member 131 by the elastic force of the elastic member 133, causing the squeezing member 131 to directly or indirectly press against the inner wall 112 of the lumen to achieve locking. When locked, the second component 120 is prohibited from moving relative to the first component 110. The unlocking member 134 is connected to the expanding member 132, and the expanding member 132 is actuated through the unlocking member 134 to overcome the elastic force of the elastic member 133 to weaken or eliminate the radial expansion of the expanding member 312 on the squeezing member 131 and the direct or indirect pressing of the squeezing member 131 against the inner wall 112 of the lumen to achieve unlocking. When unlocked, the second component is allowed to move relative to the first component.

[0055] For this locking mechanism, the expanding member radially expands the squeezing member by the elastic force of the elastic member, causing the squeezing member to directly or indirectly press against the inner wall of the lumen. When the second component moves relative to the first component, static friction is generated to prevent the movement, achieving locking and prohibiting the second component from moving relative to the first component. The action is flexible and the locking is reliable.

[0056] For this locking mechanism, the locking assembly is hidden in the lumen of the first component, with a compact structure, small occupied space, light product weight, which is beneficial to reducing the manufacturing cost of the product.

[0057] For this locking mechanism, there is no need to set gears, and the expanding member can be locked at any position on the inner wall of the lumen, achieving stepless adjustment.

[0058] For this locking mechanism, locking is achieved by using the elastic force of the elastic member and unlocking is performed through the unlocking member, with convenient operation.

[0059] In the structure shown in Figure 7, the squeezing member 131 includes Figure 8The circumferentially distributed extrusion flaps 1311 shown, the expansion member 132 is located inside the extrusion flaps 1311 and cooperates with the extrusion flaps through the inclined surface 1321. The illustrated inclined surface is provided on the expansion member 132, and the extrusion flaps are also provided with corresponding inclined surfaces. In other embodiments, the inclined surface can be provided only on the expansion member or the extrusion flaps. When the expansion member 132 moves downward by the elastic force of the elastic member 133, it radially expands the extrusion flaps 1311, causing the extrusion flaps 1311 to directly or indirectly press against the inner wall 112 of the lumen to achieve locking. When the unlocking member 134 actuates the expansion member 132 to move upward, it overcomes the elastic force of the elastic member 133 to weaken or eliminate the radial expansion of the expansion member 132 on the extrusion flaps 1311 and the direct or indirect extrusion of the extrusion flaps 1311 on the inner wall 112 of the lumen to achieve unlocking. Since the extrusion flaps have a large radial deformation ability, they can reliably press against the inner wall of the lumen to achieve locking, and can also sufficiently weaken or eliminate the extrusion on the inner wall of the lumen to achieve unlocking, ensuring reliable locking and unlocking, and avoiding incomplete locking and unlocking due to insufficient deformation ability of the extrusion member.

[0060] In the structure shown in FIG. 7, the extrusion flap 1311 has its own elastic force. When locking, the expansion member 132 overcomes the own elastic force of the extrusion flap 1311. When unlocking, the extrusion flap 1311 weakens or eliminates the direct or indirect extrusion on the inner wall 112 of the lumen by its own elastic force. Accordingly, the unlocking action is ensured to be smooth and jamming is avoided.

[0061] In the structure shown in FIG. 7, the root of the extrusion flap 1311 is made into a weak part 1312 to promote the radial elastic deformation of the extrusion flap 1311. Accordingly, on the premise of ensuring sufficient own elastic force of the extrusion flap, its radial elastic deformation is ensured to avoid incomplete locking and unlocking due to insufficient deformation ability of the extrusion flap.

[0062] Preferably, the extrusion member is made of an elastic material such as metal or engineering plastic.

[0063] In the structure shown in FIG. 7, a friction member 135 is sleeved outside the extrusion flap 1311. If the friction member is made of silicone, sufficient static friction can be generated when the silicone is pressed against the inner wall of the tubular first member made of, for example, aluminum alloy. When locking, the friction member 135 is pressed by the extrusion flap 1311 against the inner wall 112 of the lumen, that is, the extrusion member indirectly presses against the inner wall of the lumen to achieve locking. When unlocking, the extrusion of the friction member 135 on the inner wall 112 of the lumen is weakened or eliminated. Accordingly, when locking, the friction is increased by pressing the friction member against the inner wall of the lumen to ensure reliable locking. When unlocking, the friction member will contact the inner wall of the lumen and generate damping as the second member moves, causing the second member to move in a controlled manner.

[0064] In the structure shown in FIG. 7, the friction member 135 is in a ring shape, and a constraint groove 1313 is provided on the outer side of the extrusion flap 1311. The friction member 135 is located in the constraint groove 1313. To prevent the friction member from being rubbed out of position.

[0065] In other embodiments, the extrusion flap may not be elastic and only have the ability of radial deformation. For example, the weak part of the extruded part is made into a web or a structure similar to a shaft connection. At this time, a tightening member is sleeved outside the extrusion flap. When locking, the tightening force of the tightening member is overcome, and when unlocking, the extrusion flap weakens or eliminates the direct or indirect extrusion of the inner wall of the lumen by means of the tightening force of the tightening member. Accordingly, the unlocking action is ensured to be smooth and jamming is avoided.

[0066] Further, as a friction member, the tightening member is pressed by the extrusion flap against the inner wall of the lumen when locking. When unlocking, the extrusion of the tightening member against the inner wall of the lumen is weakened or eliminated. Accordingly, when locking, the friction is increased by pressing the tightening member against the inner wall of the lumen to ensure reliable locking. When unlocking, the tightening member will contact the inner wall of the lumen and generate damping as the second member moves, so that the second member moves in a controlled manner. Moreover, the tightening member is given two functions of avoiding jamming when unlocking and increasing friction when locking, and the structure is compact.

[0067] In other embodiments, the extrusion flap is directly pressed against the inner wall of the lumen to achieve locking. For example, friction features are arranged on the outer surface of the extrusion flap, and such features can be a friction material integrally formed with the extrusion flap. When locking, the friction features are pressed by the extrusion flap against the inner wall of the lumen. When unlocking, the extrusion of the friction features against the inner wall of the lumen is weakened or eliminated. Accordingly, when locking, the friction is increased by pressing the friction features against the inner wall of the lumen to ensure reliable locking. When unlocking, the friction features will contact the inner wall of the lumen and generate damping as the second member moves, so that the second member moves in a controlled manner.

[0068] In view of the fact that locking is achieved by directly or indirectly pressing the extrusion flap against the inner wall of the lumen, whether the extrusion flap has its own elasticity is optional. Whether it is necessary to sleeve a tightening member outside the extrusion flap is also optional. When the extrusion flap itself can generate sufficient friction, the friction member and the friction features are not necessary either.

[0069] In the structure shown in FIG. 7, the unlocking member 134 is led out from the second member 120 and is configured to actuate the expansion member 132 by being pulled and overcome the elastic force of the elastic member 133. Accordingly, the unlocking member is easy to be manipulated, and a steel wire rope can be used as the unlocking member, which occupies a small space and has a compact structure.

[0070] In the structure shown in FIG. 7, a support seat 136 is fixed to the first end of the second member 120, for example, the support seat 136 is fixed to the first end of the second member 120 by a radial fastener 137. The extrusion member 131 is connected to the support seat 136 by a thread, the elastic member 133 is a helical compression spring supported between the expansion member 132 and the support seat 136, and the unlocking member 134 passes through the support seat 136 and the elastic member 133. The support seat not only provides support for the elastic member to generate elastic force, but also simplifies the structure and ensures the assembly strength of the extrusion member.

[0071] When the locking mechanism 100 of the present utility model is applied to a rod 200 with adjustable length, as Figure 6 shown. The rod 200 includes the locking mechanism 100 of the present utility model. The first member 110 extends downward and then upward from Figure 7 to form a first rod, and the second member 120 extends upward from Figure 7 to form a second rod. Then, the first rod and the second rod constitute the rod. When unlocking, the length of the rod is adjusted by moving the second member relative to the first member. When locking, the relative movement of the second member relative to the first member is prohibited to fix the length of the rod.

[0072] Moreover, the first end of the second member 120 ( Figures 6-7 the lower end shown) is inserted into the lumen 111 of the first member through the second end of the first member 110 ( Figures 6-7 the upper end shown). A bushing 201 is arranged at the second end of the first member ( Figures 6-7 the upper end shown). The bushing 201 is located between the outer wall of the second member 120 and the inner wall of the first member 110. The bushing can not only guide the movement of the second member during unlocking, isolate the second member from the first member, avoid direct contact and friction between the second member and the first member, but also support the second member to prevent the second member from shaking and ensure the stability of the rod. Accordingly, the first end of the first member 110 serves as the first end of the rod, and the second end of the second member 120 serves as the second end of the rod. The tubular first member and second member can save materials and reduce weight while ensuring strength.

[0073] The rod 200 with adjustable length of the present utility model, as Figures 4-6 applied to the angle adjustment mechanism 300 of an ironing board. The angle adjustment mechanism 300 of the ironing board includes a support member 310, an ironing board 320, a handle 330, and a rod 200 with adjustable length. The ironing board 320 is rotationally assembled with the support member 310 via a first shaft a, and accordingly, the ironing board is configured to flip relative to the support member. One end of the rod 200 ( Figure 6 the upper end shown) is rotationally assembled with the ironing board 320 via a second shaft b. The other end of the rod 200 ( Figure 6 the lower end shown) is rotationally assembled with the support member 310 via a third shaft c. The first shaft a, the second shaft b, and the third shaft c are parallel. The axial projection of the first shaft a on its axis is at vertex A of triangle ABC, the axial projection of the second shaft b on its axis is at vertex B of triangle ABC, and the axial projection of the third shaft c on its axis is at vertex C of triangle ABC. The rod 200 serves as one side BC of this triangle. Accordingly, relying on the reliability of the triangle, both simplifies the angle adjustment mechanism of the ironing board and ensures reliable support for the ironing board.

[0074] By changing the length of the rod 200, the shape of triangle ABC is changed, and accordingly, the inclination angle of the ironing board is adjusted. AsFigures 1-3 As shown, when the rod 200 becomes longer, the ironing board flips to an upright posture, and when the rod 200 becomes shorter, the ironing board flips to a flat posture.

[0075] The handle 330 is linked to the unlocking member 134 and is configured to operate the handle to unlock the locking mechanism and release the handle locking mechanism. When the handle operates to unlock the locking mechanism, the length of the rod changes with the flipping of the ironing board. When the handle locking mechanism is released, the length of the rod is fixed and the flipping of the ironing board is prohibited. Accordingly, the ironing board can be reliably locked and fixed at the required angle, the operation is convenient when adjusting the angle of the ironing board, the product weight is reduced, and the product manufacturing cost is reduced. Specifically, the handle 330 is disposed on the back of the ironing board 320. A swinging member 340 is also disposed on the back of the ironing board 320. The swinging member 340 is linked to the handle 330 through a pull rod 350, and operating the handle 330 causes the swinging member 340 to swing. The unlocking member 134 is connected to the swinging member 340. Accordingly, by manipulating the handle 330 to swing the swinging member 340, the unlocking member 134 is then pulled. According to the lever action of the swinging member 340, the moving stroke of the unlocking member can be increased as needed, and the unlocking force of the unlocking member can also be increased.

[0076] The angle adjustment mechanism 300 of the ironing board of the present utility model is as Figures 1-3 shown and is applied to the hanging ironing machine 400. The hanging ironing machine 400 includes a main body 410 and an ironing terminal 420, and also includes the angle adjustment mechanism 300 of the ironing board of the present utility model. Accordingly, clothes can be hung or laid flat on the ironing board, steam is generated by the main body, and the clothes are ironed with an ironing terminal such as an iron, an ironing head, etc., improving the comfort, convenience and ironing effect of ironing.

[0077] Figures 1-3 Shows three states of a hanging ironing machine. Figure 1 In, the ironing board 320 is upright, Figure 2 In, the ironing board 320 is inclined, Figure 3 In, the ironing board 320 is flat. The three states are suitable for different ironing needs. Among them, when the ironing board 320 is inclined, it is not limited to the Figure 2 shown posture. In actual use, the ironing board can be adjusted as needed between the Figure 1 upright and the Figure 3 flat of.

[0078] Taking the illustrated structure as an example, in the natural state, the locking mechanism 100 is in the locked state by the elastic force of the elastic member 133, the rod 200 cannot be telescoped, and the length of the rod 200 is fixed. Therefore, the ironing board 320 can be maintained at Figures 1-3When the angle of the ironing board needs to be adjusted, the handle 330 is grasped to flip it, and the pull rod 350 swings the swinging member 340. The swinging member 340 pulls the expansion member 132 through the unlocking member 134 and overcomes the elastic force of the elastic member 133, weakening or eliminating the radial expansion and squeezing of the expansion member 132 by the petals 1311 and the direct or indirect squeezing of the expansion petals 1311 on the inner wall 112 of the lumen, thereby unlocking the ironing board 320. The ironing board 320 can then be flipped to the desired position, during which the length of the rod 200 changes accordingly. When the handle 330 is released, the locking mechanism 100 returns to the locked state due to the elastic force of the elastic member 133, and the position of the ironing board 320 is fixed.
