Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention provides a storage part at a high place such as a cabinet or a side wall in a room, and lowers a rotation operation lever at a position lower than the storage part. By operating it, the arm can be tilted forward or rotated and returned to the upright state, and the coat or clothes can be hung or escaped from the hanger pipe erected on the upper end of the arm. The present invention relates to a so-called lift coat hanger that can be stored.

<Prior Art> Conventional lift coat hangers have been disclosed in JP-A-60-29109.
No. 6, JP-A-61-185206, and Japanese Utility Model Laid-Open No. 58-100639, an arm made to be able to hang a coat or the like as disclosed in each of the publications is in a standing position (closed position). From
When the arm is closed by turning it down to the open position, which is the lower position of the arm tilted forward, and after removing the coat etc. at this low position, the arm is returned to the closed position which is the original position. By storing the restoring force in the return spring such as the tension spring, the compression spring, and the winding spring by using the restoring force,
The above-mentioned closing movement is performed lightly.

However, in the case of the above-mentioned conventional example, when attempting to restore from the open position to the closed position, the restoration is performed by the spring force. May occur. Therefore, in order to solve such a problem, it is proposed to add a braking force by a shock absorber as disclosed in Japanese Patent Application No. 62-90947.

However, when devising the case of rotating and lowering from the closed position to the open position as described above, in this case, since the arm torque increases as the arm descends, the maximum load (a large number of clothes) is applied at this time. Is
Since the arm is suddenly lowered, there is a danger, and no consideration is given to such a problem.

Therefore, as described above, if it is attempted to correct the danger by applying braking force to the rotation of the arm in both the up and down directions at appropriate times, a complicated mechanism such as a one-way clutch will be additionally provided. Not only does the cost increase, but there is also the problem that the work of mounting it on a cabinet or the like becomes troublesome.

<Problems to be Solved by the Invention> In view of the above-mentioned drawbacks of the conventional example, the present application simply uses the restoring spring to close the arm and attach a separate damper appropriately in the case of claim (1). Not only that, but by providing a transmission separation mechanism between this damper and the arm, the operating range of the braking force for the rotation of the arm by the damper is not only near the closed position but also near the open position. Each of them can be easily set, so that the driving force of the relevant arm is attenuated, so that the rotation can be silently stopped without danger in both the open position and the closed position, and the mechanism for that is simple. The first purpose is to make it inexpensive and to make it easy to attach to a cabinet or the like.

Further, in the lift coat hanger of the claim (1), the compression spring is adopted as the return spring, and the crank mechanism is used in which the spring is compressed by the rotation of the arm. , The torque transmitted to the arm by the compression spring is changed depending on the rotation position of the arm, whereby the torque becomes maximum around the middle portion in the movable range of the arm and becomes small near the open position and the closed position. The second purpose is to make it easier to stably hold the open and closed positions by setting the above.

In the lift coat hanger of claim (2), the above claim (1)
In the transmission separation mechanism in (1), a rotary plate provided on the movable shaft of the damper is provided with a groove having a substantially X-shaped front face, and the lower end portion of the arm is fitted into the groove. With a simple mechanism, the braking force of the damper is surely operated only within the desired operating range described above when the arm reciprocates up and down.

According to claim (3), the transmission separation mechanism is not formed between the movable shaft of the damper and the arm as described above, but the damper is provided by the movable shaft in the casing containing the viscous liquid. A rotating movable disk is used, and the transmission separating mechanism is provided between the movable shaft and the movable disk, so that the braking force of the damper can be controlled more easily and reliably. I'm trying to.

<< Means for Solving the Problem >> In order to achieve the above-mentioned object, the present application discloses in claim (1),
It has a hanger suspension pipe on the upper end, and the lower end of the arm that can be tilted forward by the rotation operation lever transmits rotation to the movable shaft of the damper fixed to the required mounting location to obtain braking force. In addition to being connected, a compression spring as a restoring spring is supported in the arm by one end supported by the arm and the other end supported by a spring receiver installed so as to be slidable on the arm. In this state, the bending amount of the compression spring can be restored to the closed position by rotating and descending from the closed position where the arm is in the upright position to the open position where the arm is in the forward tilted sideways state. In the increased arrangement, a link mechanism that links the spring receiver and the fixed plate fixed to the damper is formed, and a crank mechanism is formed by the arm and the fixed plate. The compression spring is configured to obtain a rotational drive force for restoration to the closed position of the arm via the crank mechanism, and is provided between the movable shaft of the damper and the lower end of the arm. The required operating range immediately before the arm rotates down to the open position and the same operating range immediately before the arm rotates up due to the restoring drive force of the compression spring to the closed position. The braking force is activated, and in other operating ranges,
An attempt is made to provide a lift coat hanger characterized by being provided with a transmission separation mechanism that does not operate the braking force.

Further, claim (2) is the same as in claim (1), in which the transmission separation mechanism is provided on the movable shaft of the damper to expose the rotating plate, and the front plate substantially X-shaped not provided on the rotating plate. The lower end of the arm is inserted into the groove of the arm, and the lower end of the arm abuts on the groove just before the opening position of the arm and immediately before the closing position of the arm, and rotates on the movable shaft of the damper. It is characterized in that each side wall for transmitting is transmitted.

The lift coat hanger of claim (3) has a hanger suspension pipe at the upper end, and the lower end of the arm that can be tilted forward by a rotation operation lever is fixed to a required mounting point on a movable shaft of a damper. The arm is connected to obtain the braking force by transmitting the rotation to the arm, and the arm is rotated and lowered from the closed position in the upright state to the open position in the forward tilted sideways state. Is provided with a restoring spring capable of returning to a closed position, and the damper has a viscous shear resistance based on a movable disc that is rotated in a casing containing viscous fluid when the rotation of its movable shaft is transmitted. , The braking force is obtained, and between the movable shaft and the movable disk, the required operating range immediately before the arm is rotated and lowered to the open position, and the same arm is restored. A transmission disconnection mechanism is provided in which the braking force of the damper is activated only in the required operating range immediately before it is rotated up by the rotational driving force for restoring the spring to the closed position and the braking force is not activated in other operating ranges. That is the content.

<Operation> In the case of the lift coat hanger according to claim (1),
An external force generated by the pulling force of the rotation operation lever is applied to the arm as a rotational force, so that the arm in the upright state when closed will rotate forward around the fulcrum of the arm, and will reach the open position in the forward tilted state. It descends and is stopped.

As described above, when the arm is rotated and lowered, the compression spring for restoration is deformed and the return force of the arm is accumulated.

When the arm descends to the open position, the arm can be stopped at the open position by setting a imaginary point or providing a locking device that does not revert.

On the other hand, the braking force does not act on the arm by the damper up to about the middle portion within the movable range of the arm, but when the arm is rotated and lowered from this, a damping effect occurs and the braking force acts on the arm.

Therefore, although the arm rotates and descends rapidly halfway, it gradually rotates near the open position and stops at the open position.

Also, to put the arm into the closed state, the arm is pushed up by the rotation operation lever and raised in rotation, but in this case as well, since the braking force does not act on the arm up to halfway, the rotation rapidly rises and closes. When the damper approaches the hour position, a braking force is applied by the damper, so that the arm gradually rotates and rises, and is stopped and held at the closed position in the upright state.

Further, the compression spring is compressed by the crank mechanism via the spring bridge when the arm is rotated and lowered, and thereby the return force of the arm is stored, and further, the center line of the arm is the fulcrum of the arm. And the position reached on the straight line connecting the lower end pivot point of the link arm (puzzle point)
Then, the bending amount of the compression spring becomes maximum, and by further rotating and lowering the arm, the compression spring expands, the return force of the arm gradually weakens, and finally at the arm open position. It reaches zero.

According to claim (2), the lower end portion of the arm is pressed against the side wall of the groove having a substantially X-shaped front surface as the transmission disconnecting mechanism at a suitable time, whereby the arm transmits rotation to the movable shaft of the damper. Therefore, in the required operating ranges immediately before the open and closed positions of the arm, the braking force by the damper is smoothly received to ensure the gentle rotation.

According to claim (3), the transmission separation mechanism is formed between the movable shaft of the damper and the movable disc, and even if the rotational force of the arm is constantly transmitted to the movable shaft, the transmission separation mechanism is not in the predetermined operating range of the arm. , The movable shaft does not rotate the movable disc, the movable shaft rotates the movable disc, and only when the movable disc rotates, the shear viscous resistance due to the movable disc based on the viscous fluid of the damper acts, and as described above. The braking force by the damper can be applied only within the predetermined operating range, and thereby the stationary state of the arm at the time of gentle opening and closing is secured.

«Examples» Examples of the present invention will be described below with reference to the drawings.

The arm 1 shown in FIGS. 1 to 3 is formed in a V shape on the side surface, and has a pipe for suspending a hanger a and the like at its upper end portion as illustrated in FIG. The hanger-hanging pipe 2 with a rod is mounted horizontally, and
A rotation operation lever 3 for rotating the arm 1 in both up and down directions is provided so as to vertically rotate the arm 1.

Of course, the rotating operation lever 3 is not the arm 1,
You may make it attach to the hanger suspension pipe 2.

The lower end of the arm 1 is attached to the damper 4 by screws 5 ...
In the fixed plate 6 which is fixed by, the center of the fixed plate 6 is pivotally attached by a shaft 7 so that it can be rotated in the front-back (up-down) direction.

Here, in the case of claim (3) as the restoring spring 8 used to apply the restoring rotational driving force to the arm 1 as described later, various springs can be used as described above. According to claim (1), a compression spring is used. The compression spring is internally mounted with one end (upper end) supported by the receiving shaft 9 fixed to the arm 1, and A spring holder 10 that supports the other end (lower end) of the restoration spring 8 that is a spring.
However, the arm 1 is internally slidable in the longitudinal direction.

In the illustrated example, the spring receiver 10 includes two spring receiver main bodies 10a that are curved so as to have a substantially inverted U-shape on the front surface so that they can slide smoothly in the arm 1 and two outer diameters corresponding to the inner diameter of the arm 1. The rollers 10b, 10b are rotatably supported to the outside of the main body 10a by pins 10d, 10d via receiving guides 10c, 10c.

Further, as shown in FIG. 3, a lever receiver 11 is fitted into the opening 1a formed by notching on one side near the upper end of the arm 1, and the lever receiver 11 is fitted to the upper end of the arm 1. The arm cover 12 is slightly movable in the left-right direction along the notch 12a, so that the rotation operation lever 3 can be moved in the front-rear direction and the left-right direction.
On the other hand, the rotation operation lever 3 can be attached by changing its direction from the right side or the left side, and even if the arm 1 as shown in the drawing is not only a single type but also a double type, Either one or both levers can be used.

When the arm 1 is made of a thin pipe as in the illustrated example, two reinforcing plates 13 and 13 formed in a substantially gutter shape are provided outside the lower end of the arm 1 in order to reinforce the lower end pivotally connecting portion. A shaft 7 is pivotally supported by the fixed plate 6 in a fitted and fixed state.

Further, the link arm 14 is provided at the lower end of the spring receiver 10.
One end (upper end) of the is pivotally attached by the pin 10d so as to be rotatable.

The link arm 14 may be a single member, and those formed in the same shape as shown in the figure are arranged on both the left and right sides of the roller 10b so as to be pivotally attached to the spring receiving body 10a by the pin 10d. You can also use it.

The lower end of the link arm 14 is slanted and descends outward from a vertically elongated window hole 1b formed by cutting out to one side of the lower end of the arm 1, and the lower end is supported by the fixing plate 6 so as to be rotatable by a pin 15. By doing so, the crank mechanism A is made by the arm 1, the fixed plate 6, and the link arm 14 described above.
Are formed.

Here, as shown in FIG. 1, the lower end pivot point P by the pin 15 of the fixed plate 6 and the link arm 14 is the arm 1
Is located forward from the fulcrum O of the shaft 7 by a proper size, and is provided at a position below the horizontal straight line b passing through the fulcrum O by a small size, whereby the pivot point P and the fulcrum O are provided. The extension line c connecting the two points is designed to be a later-described thought point when the arm 1 is opened by rotating the arm 1 forward and down.

Further, when the arm 1 is closed, the inclination angle thereof is arbitrarily set in advance so that the arm 1 can be held upright at a desired angle α behind the vertical line d passing through the fulcrum O, that is, tilted leftward in FIG. The link arm 14 is pivotally attached by setting.

When the arm 1 is rotated forward from the closed position R ₁ shown by the solid line in FIG. ₁ , that is, in the right direction in the figure about the fulcrum O, the lower end pivot point P of the link arm 14 and the fulcrum O are separated. Due to the relative positional relationship, the spring receiver 10 is slid in the direction of being pushed into the arm 1 by the link arm 14, whereby the compression spring is compressed and the driving force in the direction of rotating and raising the arm 1 is stored. Energized.

The amount of deflection of the compression spring, which is the restoration spring 8, is
Since the arm 1 is maximized on the straight line c, the open position R ₂ of the arm 1 is set at the position where the arm 1 is rotated and lowered by the desired angle β, whereby the arm 1 is shown in FIG. It is stopped and held at the open position R ₂ shown by the middle two-dotted line.

Therefore, when the arm 1 is pushed up and rotated from the open position R ₂ to a position slightly exceeding the straight line c, thereafter, the driving force stored in the elastic spring causes the arm 1 to rotate up and close. It stops at the hour position R ₁ , and this state is maintained.

When the fixing plate 6 is formed of a thin metal plate as shown in the figure, the boss 16a,
A disc-shaped bearing 16 having a protruding 16b and a disc-shaped bearing 17 having boss holes 17a and 17b are superposed on both sides of the fixed plate 6 to be integrated with each other to reinforce the fixed plate 6. Is good.

Further, the damper 4 is formed so that a braking force is applied when the arm 1 is rotated and lowered and when the arm 1 is rotated and raised, and the action range of the braking force is when the arm 1 is rotated and lowered. The rotation plate 18 is set differently when it is rotated and raised. Therefore, in the illustrated example, as clearly shown in FIG. 2, the rotating plate 18 that rotates together with the movable shaft (not shown) of the damper 4 and the lower end portion of the arm 1 are provided. A transmission separating mechanism B is provided between them.

That is, in the illustrated example, the rotary plate 18 of the damper 4 is provided with a groove 19 having a substantially X-shaped front surface, and the groove 19 is provided in the groove 1.
The transmission disconnecting mechanism B is formed by fitting the above.

When the arm 19 reaches the position R ₃ which is rotated and lowered from 0 ° when the arm 1 is in the closed position R ₁ to 65 °,
The upper and lower side walls 19a, 19a of the groove 19 come into contact with the arm 1 to exert a damper effect, and a braking force acts on the arm 1 in the operating range from the position R ₃ to the open position R _2. .

In addition, when the arm 1 is rotated and raised from the open position R ₂ to the closed position R ₁ , the arm 1 is rotated from the open position R ₂ to 100 ° and then moved from the position R ₄ to the closed position R ₁ . The groove 19 has the X-shape as described above so that the damper effect is exerted in the operation range and the braking force acts on the arm 1.

That is, when the arm 1 is rotated and lowered forward to approach the open position R _2, and when the arm 1 is rotated and raised to the upright position, the closed position R _{1 is set.}
As the braking force is applied to the arm 1, the rotation speed of the arm 1 is decelerated, and the open position R ₂ and the closed position R _{1 are} gently released.
It is configured to rotate up to and be held at respective positions R ₂ and R ₁ .

As the damper 4 according to claim (3), which will be described later with reference to FIG. 6, a high-viscosity polymer such as polyisobutyne is filled between the fixed plate 20 and a movable disk having an interior not shown, and between the movable disk and the plate body 21. By sealing with an O-ring and packing (not shown), the viscous shear resistance of the viscous body is generated when the movable disk receives a rotational force from the rotary plate 18 via a movable shaft (not shown) of the damper. The damper 4 used in claim (1) is used so that a resistance force is obtained by utilizing the above, and a buffering action against an external force, that is, a braking force is exerted by the resistance force. Is not limited to the one described above, and it is possible to use a known spiral spring as a drive source.

When the one having the above structure is used, the plate body 21 of the damper 4 is a cabinet 22 as illustrated in FIGS. 4 and 5.
No. 2 on the inner surface of the lower part of the side plate of the storage chamber 23 provided at a high place of
It is fixed with screws 24 shown in the figure, and the arm 1 is attached so as to be able to rotate and descend in the forward tilted state as shown by the two-dot broken line in FIG.

When the arm 1 is closed, it is held in an upright state as shown by the solid line in the figure, and clothes not shown are stored in the storage chamber 23 by suspending them on the hanger suspension pipe 2 using the hanger a. To be done.

When the rotation operation lever 3 is pulled obliquely downward in the above-mentioned closed state, the arm 1 rotates forward and downward about the shaft 7 and is held in the open position R ₂ in the forward tilted state. You will be putting in and taking out clothes.

In FIG. 2, reference numeral 25 indicates a cover.

Next, in the lift coat hanger according to claim (3), the damper 4 as shown in FIG. 6 is used, and the movable shaft 26 shown in FIG. A transmission separation mechanism B is provided between the movable disks 27 and the number of movable disks 27.

Here, the damper 4 shown in FIG. 6 will be described in detail.
The casing 28 having a concave cross-section has a bearing recess 2 on the bottom wall 28a thereof.
8b is provided, and longitudinally elongated groove grooves 28d, 28d are provided to face the inner surface of the peripheral wall 28c.

The movable shaft 26 has its tip (lower end in the figure) fitted in the shaft receiving recess 28b, so that the casing 2
While being rotatably supported in the axial direction on the center line of 8, the angular head portion 26a of the movable shaft 26 is projected through the shaft hole 29a penetrating the center of the cover plate 29 of the casing 28. There is.

The cover plate 29 is screwed to the upper female screw portion 28e of the casing 28 so as to be closed, and the shaft hole 29a and the movable shaft 2 are provided.
The space between 6 and 6 is also kept airtight by a known means such as a seal.

The projecting end of the square head 26a is fitted with the square hole 1a of the arm 1 on which a rotational force as an external force acts, and in order to prevent the arm 1 from coming out, the retaining screw 30 is provided on the square head 26a. It is screwed into a screw hole (not shown) formed in the end face of 26a.

In this way, the casing 28 closed by the lid plate 29
The polymer viscous material such as polyisobutylene or the like or the viscous fluid C such as pitch or high-viscosity water glass is accommodated in the inside, and the required number of the viscous fluid C, that is, 2 in the illustrated example. The movable disks 27 and the fixed disk 31 are arranged in the vertical direction alternately (in the illustrated example, the fixed disks are arranged between the upper and lower movable disks) as follows. It is set up.

That is, a spline 26b is formed at a position inside the casing 28 of the movable shaft 26, while each movable disk 27 has a shaft hole 27a at its center and an inner diameter of the movable shaft 26. The opening is made larger than the diameter of the spline 26b in the above, and a plurality of (four in the illustrated example) engaging claws 27b ... Are centered in the circumferential direction from the inner circumference of the shaft hole 27a. By being engaged with the splines 26b by being projected toward the movable shaft 26b.
The movable disk 27 is also rotated with the rotation of the movable disk 27. The engaging claws 27b of both movable disks 27 ...
Are engaged with the spline 26b with different clearances D in the circumferential direction.

That is, since the spline 26b in the illustrated example is one in which four engaging projections 26c are vertically provided on the movable shaft 26 at equal intervals in the circumferential direction, the engaging projections 26c ... Four engaging claws 27b of each movable disk 27 are provided at equal intervals in the circumferential direction so that they can be fitted together.

Of course, each movable disk 27 is movable with respect to the movable shaft 26 in the axial direction thereof, that is, in the plate thickness direction.

Next, the fixed disk 31 has a shaft hole 31a at its center, whose inner diameter is larger than the diameter of the spline 26b of the movable shaft 26, so that the fixed disk 31 is not interlocked with the rotation of the movable shaft 26. The movable shaft 26 is loosely inserted in the shaft hole 31a.

Further, a plurality of required rotation stopping projections 31b, 31b are projected at symmetrical positions on the outer peripheral edge of the fixed disk 31, and the rotation stopping projections 31
b, 31b is engaged with the vertically elongated groove 28d of the casing 28,
As a result, the fixed disc 31 does not follow the rotation of the movable shaft 26, and the variation in the thickness direction of the movable disc 27 does not occur.
It is as free as.

Therefore, when the above-mentioned damper is used, even if the movable shaft 26 rotates when the external force acts on the arm 1 as the rotational force, the engaging ridges 26c of the splines 26b move each movable ridge 26c. Since the engaging claw 27b of the disk 27 is not engaged, the movable disk 27 does not rotate, and the viscous shear resistance does not act.

When the movable shaft 26 rotates from the state shown in FIG. 7 to the state shown in FIG. 8 by the clearance D, the spline 26b engages with the engaging piece 27b of the movable disc 27, and the movable disc 2
The 7 rotates together with the movable shaft 26. Therefore, the viscous shear resistance force based on the viscous fluid C existing between the plate surfaces of the movable disk 27 and the non-rotating fixed disk 31 acts. .

In the illustrated example, the movable disk 27 is composed of two movable disks 27 and one fixed disk 31. However, other than this, a plurality of required movable disks 27 ... Yes, you can also remove the fixed disc 31,
The number of movable disks 27 may be one.

<Effects of the Invention> Since the present application is configured as described above, according to claim (1), since the damper is operated in a timely manner, the operation of the arm is controlled by the braking force of the damper to the open position and The rotation can be gently and quietly stopped toward the closed position, and the mechanism can be simplified and provided at low cost.

Furthermore, the compression spring as a spring for restoration,
By rotating and lowering the arm, the arm is compressed via the crank mechanism A and the driving force of the arm is obtained. For example, the torque transmitted to the arm can be adjusted by, for example, replacing the link arm. Can be maximized in the middle part of the arm rotation range and weakened on both sides, and the range of action of the braking force of the arm by the damper can be increased when the arm is rotated up and when it is rotated down. The rotation speed is attenuated as the arm approaches the closed position R ₁ and the open position R ₂ , and the arm is statically stopped and held at each of the positions R ₁ and R _{2 as} described above. The arm is locked in the open position R ₂
It is possible to make it safe and excellent in operability by obtaining the feeling of N, OFF.

According to claim (2), the transmission separation mechanism is required to engage the substantially X-shaped groove provided in the rotary plate with the lower end portion of the arm. The braking force by the damper can be exerted only within the desired operating range.

In claim (3), unlike the claim (2), the transmission separation mechanism is configured between the working shaft of the damper and the movable disk, so that a more accurate braking force can be obtained. It is possible to specify the working range of exertion.
