As shown, the stand-type clothes drying rack by the angle adjusting and hinge fixing means according to the present invention is a pair of swash tables 10 and 10 ', both ends of which are bent to face the same direction, and both ends are equal to each other. In the state having a pair of wing drying racks 20, 20 'bent to face in the direction of the hinges 10, 10' and wing drying racks 20, 20 ' 30) (30 ') formed by bonding,

In the uprights 10 and 10 ', connecting rods 11 connecting them to each other are formed in the middle portion, thereby limiting the spreading width of the uprights 10 and 10' through the connecting rods 11 to the horizontal state. Various laundry can be hanged on the developed connecting rod 11 and dried.

In addition, as the hook rods 21 in the lateral direction are arranged in a row in the wing drying racks 20 and 20 ', various laundry can be hanged on the hook rods 21 and dried.

At this time, the hinged fixtures 30 and 30 'for hinge-engagement of the uprights 10, 10' and the wing drying racks 20, 20 'are vertically divided into a hinge body 32 and a cover body 33. And a fixing pin (31) (31 ') and hinge clamping means (40, 40') are located at one side of the hinge body (32), and the cover body (33) is closely attached to one side of the hinge body (32). If one is firmly coupled to each other using a separate fastening bolts 50 and 50 ', the fixing pins 31 and 31' and the hinge clamping means 40 and 40 'are hinge body 32 and cover. It is concealed and built in between the main bodies 33.

Here, before the cover body 33 is coupled to the hinge body 32, the cover body 33 is opened in a state where the hinge combinations of the uprights 10, 10 'and the wing dryers 20, 20' are completed. As to be assembled, this is because the cover body 33 is coupled to the hinge body 32 and at the same time the assembly of the laundry dryer is completed.

Accordingly, the pair of three rods 10 and 10 'is coupled to the fixing pins 31 and 31' protruding from the lower side of the hinge body 32, but the rods 10 and 10 ' The fixing pins 31 and 31 ′ are rotatably coupled to the axial point, and the cover body 33 is coupled to the hinge clamping means 40 and 40 ′ after engaging the ends of the wing driers 20 and 20 ′. Combine it.

In addition, as the stopper 34, 34 'protruding stoppers 34 and 34' are formed on the side of the fixing pins 31 and 31 ', the ends of the uprights 10 and 10' which are rotated outwardly are formed as stoppers 34 and 34. May be configured to limit the deployment width to the uprights 10 and 10 '.

In this case, the hinge clamping means 40 and 40 'are freely rotated by being located inside the rotary hole 41 and the rotary hole 41 inserted into the hinge pins 44 and 44' protruding from the hinge body 32. It consists of the wedge 43 in the state gear-coupled with the possible interruption | blocking plate 42 and the rotating hole 41, and hinge-stopping means 40 (the both sides with respect to the single hinged fixture 30, 30 ') ( As the 40 'is formed symmetrically, the wing racks 20 and 20' can be individually upwardly deployed on both sides.

That is, the rotating sphere 41 in the hinge interrupting means 40, 40 'is coupled to the wing drying rack 20, 20' at one end, the gear plate having a gear 41a of the gear shape at the other end ( 41b) and 41b 'are mutually spaced apart in the horizontal direction, and the protruding locking release 41c is formed between the gear plates 41b and 41b'.

In addition, the intermittent plate 42 is made of a circular metal plate material, the outer diameter of the intermittent plate 42 is composed of an outer diameter smaller than the outer diameter of the gear plates 41b, 41b 'and the gear plate 41b on one side. The unlocking surface 42a having an outer diameter larger than the outer diameter of the upper portion 41b 'is formed to partially protrude, and one side of the unlocking surface 42a has a flow groove portion having an outer diameter smaller than the outer diameter of the interrupting plate 42. 42d) is formed, the first interference surface 42b and the second interference surface 42c by the step will be naturally formed on both sides of the flow groove portion 42d, and the gear plate 41b inside the flow groove portion 42d. ) 41b 'will be released.

At this time, the intermittent plate 42 is inserted on the hinge pin 44 so that the hinge pin 44 can be freely rotated by the axial point. The free rotation point of the intermittent plate 42 is the first interference by the flow groove 42d. It will be limited within the range of the plane 42b and the second interference plane 42c.

In addition, the wedge 43 is to be elastically coupled upward by the elastic body 43a having one end fixed to the hinge body 32, the end of the wedge 43 is a tooth 41a of the gear plate 41b (41b ') The gear plates 41b and 41b 'are freely rotated in the forward direction by the holding force of the wedge 43 coupled horizontally from the lower side of the toothed tooth 41a. On the other hand, the reverse rotation is not made due to the engagement with the wedge 43.

That is, the end of the wedge 43 is coupled to the teeth 41a at the bottom of the gear plates 41b and 41b ', so that the gear plates 41b and 41b' rotate downward at the engaging portion with the wedge 43. When the wedge 43 is pushed outward, free rotation is performed, whereas when the gear plates 41b and 41b 'try to rotate upward, the coupling force between the wedge 43 and the teeth 41a becomes more firm and eventually the gear plate ( 41b) 41b 'is in the form of a ratchet gear which cannot rotate.

Here, one side of the teeth (41a) may be formed in a curved shape to minimize the friction between the wedge 43 and the teeth (41a) when the wing drying rack 20, 20 'is deployed upward.

Accordingly, the first teeth 41a and the wedges 43 are coupled to each other in a state in which the wing drying racks 20 and 20 'are folded in the vertical direction downward, and then the upright rotation of the wing drying racks 20 and 20'. As the wedge 43 is coupled to the teeth 41a continuously formed on one side of the gear plates 41b and 41b ', the wing racks 20 and 20' can be rotated and fixed at various deployment angles. .

If described in more detail by the accompanying drawings, the upward development action and the down folding process of the wing drying stand as follows.

In order to deploy and install the stand-type clothes dryer in the state where the above-mentioned stand (10) (10 ') and the wing dryer (20) (20') are vertically folded side by side, the holder (10) (10 ') and the dryer stand As shown in FIG. 6, when the 20 and 20 'are rotated outwardly, the uprights 10 and 10' are rotated using the fixing pins 31 and 31 'as the axial point, and one end of the Interfering with the stoppers 34 and 34 ', it has a predetermined deployment angle.

Then, when the wing drying rack 20, 20 'is rotated upward, the rotating plate 41 on the hinge clamping means 40, 40' in the hinged fixture 30, 30 'is rotated upward, and the gear plate 41b ( The wedge 43 is coupled to the teeth 41a of 41b ') to achieve a predetermined deployment angle.

Here, Figure 6 is a wing drying rack upward rotation operation of the laundry drying machine according to the present invention.

As described above, the wing drying racks 20 and 20 'in the unfolded state may be undeveloped due to the reverse rotation prevention structure of the gear plates 41b and 41b' by the wedge 43 in the unfolded state. You can keep it as it is.

7 is a view showing a state in which the wing drying racks 20 and 20 'are raised as far as possible, and typically, the wing drying racks 20 and 20' have a deployment angle of 115 ° to 125 ° from the vertical direction. It is ideal to make this maximum, and the expansion fixed angle is divided and set by the number and space | interval of the tooth | gear 41a in such a deployment angle.

Here, Figure 7 is a wing drying rack up fixed operation of the laundry dryer according to the invention.

Therefore, the user can be used to vary the deployment angle of the wing drying racks 20, 20 'arbitrarily variously, but the fine deployment angle or 85 ° ~ 95 °, 100 ° ~ 110 °, It can also be configured to form an intermittent development angle, such as 115 ° ~ 125 °.

In addition, when the wing drying racks 20 and 20 'are rotated upward by 115 ° to 125 ° or more, the release mechanism 41c in the gear plates 41b and 41b' starts at this time the first interference in the flow groove 42d. The surface 42b is brought into contact with each other, and as the gear plates 41b and 41b 'continue to rotate, the intermittent plate 42 is rotated downward.

Accordingly, from this time, the wedge 43 is forced down to rotate by the unlocking surface 42a of the intermittent plate 42. As shown in FIG. 8, the gear plates 41b, 41b 'and the wedge 43 are rotated. The combined state of is released.

Here, Figure 8 is a wing drying lock unlocking operation of the laundry drying rack according to the present invention.

Therefore, as shown in FIG. 9, the wing drying racks 20 and 20 ′ rotated upward in a state where the gear plates 41b and 41b 'and the wedge 43 are disengaged can be naturally rotated downward. On the other hand, the intermittent plate 42 will not be rotated by the close friction with the wedge 43, and the release mechanism 41c in the gear plates 41b and 41b 'is downwardly moved along the flow groove 42d. When the rotation is in contact with the second interference surface 42c of the intermittent plate 42 in the non-rotated state, reverse rotation of the gear plates 41b and 41b 'and the intermittent plate 42 occurs at this time.

Further, the wedge 43 at the moment when the unlocking surface 42a and the wedge 43 formed on the intermittent plate 42 are separated from each other after the reverse rotation of the gear plates 41b and 41b 'and the intermittent plate 42 are simultaneously performed, The 43 is coupled to the teeth 41a of the gear plates 41b and 41b 'by the restoring force of the elastic body 43a.

Here, Figure 9 is a wing drying rack downward rotation operation of the laundry dryer according to the invention.

As such, the engagement state of the wedge 43 and the teeth 41a may be made in a state in which the wing drying racks 20 and 20 'are completely folded downward in the vertical direction as illustrated in FIG. 10.

Here, Figure 10 is a wing drying rack downward folding operation of the laundry dryer according to the invention.

Therefore, in the folded state, the wing drying racks 20 and 20 'are uncomfortable due to the coupling force between the teeth 41a and the wedges 43, and thus the inconvenience of transportation and handling thereof. It is possible to prevent the wing drying racks 20, 20 'that do not flow by themselves do not collide with other components, so that the friction noise is greatly reduced.

Therefore, it is not only possible to expand and secure the wing drying racks 20 and 20 'at various angles required by the user without requiring various supporting means for setting up and fixing the wing drying racks 20 and 20' as in the related art. Its simple appearance gives it a simple and luxurious aesthetic.
