[Problem to be Solved by the Invention] In this conventional hanger device, the strength of the return spring is set so as to provide a restoring force commensurate with the relatively light weight of the clothes hanging from the hanging rod. . Then, if the weight of the clothing is heavy, in the process of lowering the hanging rod in an arc as described above, the restoring force will overcome the rotational force due to the weight of the clothing until halfway through, and after that, the rotational force will be stronger. There was a problem in which the restoring force was overcome, and the direction of the force applied to the hand operating the hanging rod reversed during the descent, making it feel strange. In addition, in order to cope with such heavy weight clothes, if the above-mentioned return spring has a strong spring force,
If the weight of the clothes is light, a great deal of force is required to pull down the hanging rod, which poses a problem in that weak women cannot operate it.

The present invention was made in order to solve the problems (technical problems) of the prior art described above, and by making it possible to select one or two return springs that exert a restoring force, the weight of clothes can be reduced. We have developed a hanger device that enables smooth lifting and lowering of the hanging rod whether it is light or heavy, and as a result, the spring force of the return spring can be easily set. is intended to provide.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the hanger device of the present invention has a lower end of the arm that can be freely raised with respect to a base for mounting on a wall surface such as a wardrobe. In the hanger device, the upper end of the arm is attached with a recumbent hanging rod for hanging clothes. When the suspension rod is lowered in an arc, each return spring applies a restoring force to the arm in a direction that restores it and that increases as the forward tilt angle of the arm increases. In addition, one end of one of the return springs is connected to the base, or the other end of the return spring and the arm are connected via a switching means that allows the two to be freely brought into contact with and separated from each other. It is.

[0006]

[Operation] When the weight of the clothes is light, one of the return springs and the base or arm are separated by operating the switching means. Then, a relatively weak restoring force is applied to the arm only by the other restoring spring. On the other hand, if the clothes are heavy, one of the springs is connected between the base and the arm by operating the switching means. Then, a relatively strong restoring force is applied to the arm by both the one and the other return springs.

[0012] The usage method and usage condition of the hanger device 1 having the above structure will be explained. The hanger device 1 is used by attaching the base 2 to the side wall of a wardrobe 57, for example, as shown in FIG. In this state, the hanging rod 4 is in a recumbent state. Also, in that state, the hanging rod 4 (or arm 3
An operating rod 58 is connected in a well-known manner near the free end of the . Then, as shown in FIG. 4, the user raises and lowers the arm 3 via the operating rod 58 to move the hanging rod 4 as shown by an arrow 60, and hangs the clothes 59 on the hanging rod 4 in the folded position. By removing the arm 3 and placing the arm 3 in the upright position, the clothes 59 are stored in the upper position inside the wardrobe 57. Although not shown in the drawings, the base 2 is provided with a well-known locking mechanism that can hold the arm 3 in the collapsed position and release the holding. Therefore, clothes can be easily hung on and taken off in the lying position.

Next, the operation of the hanger device 1 when used as described above will be explained. When the arm 3 is in the upright position, the first return spring 23 is in a slightly compressed state, and as a result, the return spring 23 maintains a slight restoring force on the arm 3, that is, maintains the arm 3 in the upright state. provides sufficient resilience. Due to the restoring force, the connecting frame 21 in the arm 3 is in contact with the stopper 17,
As a result, arm 3 is held in the upright position shown in FIG.

Next, when moving the arm 3 to the lying position, if the weight of the clothes being hung or the clothes to be hung is small, the switching means 46 is switched off while the arm 3 is in the upright position. state. That is, the switching lever 5
2 as shown in imaginary lines in FIG. 1 to move the engaging piece 49 to a retracted position where it does not face the engaging portion 45. When the arm 3 is tilted forward about the support shaft 7 in this state, the engagement piece 49 moves without engaging the engagement portion 45, as shown in FIG. Therefore, the second return spring 41 does not apply a restoring force to the arm 3. On the other hand, the cable body 2 connected to the first return spring 23
9 is wound around the winding portion 15 as the arm 3 is tilted forward. As a result, the return spring 23 is compressed via the connecting rod 26 and the piston 25. As a result, the restoring force exerted on the arm 3 by the return spring 23 gradually increases as the forward tilt angle of the arm 3 increases.

On the other hand, if the weight of the clothes hanging from the hanging rod 4 or the clothes to be hung is heavy, the arm 3
The switching means 46 is brought into the contact state while the switch is in the upright position. That is, the switching lever 52 is brought into a state as shown by the solid line in FIG. When the arm 3 is tilted forward in this state, the engagement piece 49 engages with the engagement portion 45, and as the forward tilt angle of the arm 3 increases, the second return spring 41 is tightened as shown in FIG. To go. Therefore, the return spring 41 is
The restoring force increases as the forward tilt angle of the arm 3 increases. Further, since the first return spring 23 is compressed in the same manner as in the above case, the spring 23 applies a restoring force to the arm 3 in the same manner as in the above case. As a result, the restoring force of both the first return spring 23 and the second return spring 41 is applied to the arm 3, and the restoring force becomes extremely large.

Next, when the arm 3 returns to the standing position, the first return spring 23 gradually expands and the restoring force applied to the arm decreases, contrary to the above operation. In this case, even if the arm 3 is returned to its original position by the restoring force of the first restoring spring 23 after the user releases the operating rod 58, the buffer mechanism 31 causes the arm 3 to return slowly. That is, since the air in the space 33 must be exhausted through the narrow ventilation hole 34, the exhaust is performed slowly. Therefore spring 2
The speed at which the piston 25 moves toward the closing body 32 due to the biasing force 3 is slow, and as a result, the arm 3 returns slowly. When the second return spring 41 is in operation, the arm 3 is returned with the restoring force of the spring 41 also applied. In that case, the spring 41 gradually loosens as the arm 3 returns, and the restoring force applied to the arm 3 decreases.

Next, FIG. 5 shows the relationship between the forward inclination angle of the arm 3, the rotational force exerted on the arm 3 by the weight of the clothes 59, and the restoring force exerted on the arm 3 by the return spring during use as described above. It is something. (a) shows the turning force when the weight of the clothing 59 is small, for example 15 kg, and (b) shows the restoring force exerted on the arm 3 only by the first return spring 23 when the switching means 46 is turned off. show. Also, (c) shows the rotational force when the weight of the clothes 59 is heavy, for example 30 kg, and (d) shows the rotational force when the switching means 46 is in contact with the first return spring 23 and the second return spring 41. Arm 3
It shows the resilience exerted on the

Next, FIGS. 8 to 11 showing different embodiments of the present application will be described. In this example, the first return spring 23
This shows an example in which a spiral spring is used as e. As shown in FIG. 9, one end 71 of the return spring 23e is fitted into a fitting part 72 formed on the support shaft 7e, and the other end 73
is provided with a hook-shaped engaging portion 73a, which is connected to the arm 3.
It is engaged with a spring hook 74 fixed to the connecting frame 21e at e. Reference numeral 75 denotes a long hole formed in the base 2e to allow movement of the spring hanging piece 74 as the arm 3e tilts forward, and is formed in an arc shape centered on the support shaft 7e. Reference numeral 76 denotes a back cover for covering the above-mentioned return spring, and is detachably fixed to the base 2e. It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted. (Also, in the following figure, the same idea is given by adding the letter f and redundant explanation will be omitted.)

Next, FIG. 12 shows a further different embodiment of the present application, in which one end of the second return spring 41f and the base 2f
This shows an example in which these are connected via a switching means 46f. The configuration of the switching means 46f will be explained based on the figure. Support shaft 7
A fitting hole 81 is bored in f. An overhanging piece 82 is provided at the inner peripheral end of the return spring 41f that is loosely fitted to the support shaft 7f, and the overhanging piece 82 is provided with the above-mentioned fitting hole 81 when the arm 3f is erected. A through hole 83 is bored at the position where they overlap. Reference numeral 84 denotes a connecting pin that is inserted through the through hole 83 and the fitting hole 81. With this configuration, when the pin 84 is not inserted, the connection between the second return spring 41f and the base 2f is broken, and the restoring force by the return spring 41f is not applied to the arm 3f. Only a restoring force by a first restoring spring (not shown) is applied to the arm 3f. On the other hand, when the pin 84 is inserted, the second return spring 41f and the base 2f are connected, and a restoring force by both the first and second return springs is applied to the arm 3f.

[0020]

As described above, in the present invention, when the weight of the clothes to be hung from the hanging rod 4 is light, for example, when the clothes are thin and light as in the summer, one By applying a restoring force to the arm 3 by the return spring 23, as is clear from the correspondence between (a) and (b) illustrated in FIG. 5, the weight of the clothes is applied to the arm 3. It has the advantage of making it possible to make the difference between the rotational force and the restoring force by the one return spring 23 relatively small, thereby making it possible to smoothly raise and lower the hanging rod 4.

Further, when the weight of the clothes to be hung on the hanging rod 4 is heavy, for example when the clothes are thick and heavy as in winter, the two return springs 23 and 41 apply a restoring force to the arm 3 by operating the switching means 46. As is clear from the correspondence between (c) and (d) illustrated in FIG. , 41 is relatively small, and the lifting rod 4 can be raised and lowered smoothly as in the case of the light load described above.

As described above, in the present invention, by selecting one return spring 23 or two return springs 23, 41 using the switching means 46, even if the weight of the clothes increases or decreases, However, since it is possible to apply a restoring force commensurate with each weight, the spring force of the return spring can be set extremely easily.
