  By the way, generally, in a folding-type hanger, it is necessary to provide a predetermined holding force with the arm opened and locked. For example, when a heavy load is applied to the hanger arm, such as when heavy heavy clothing is hung on the hanger, or when the arm is pulled downward by a hand or the like being caught by the hung clothing. When the arm is unlocked and closed, the troublesome work of opening the arm again and hanging the clothes on the hanger becomes necessary. In particular, when such troublesome work frequently occurs, the user becomes dissatisfied and becomes a factor of reducing the commercial value. Therefore, it is necessary to ensure a sufficient holding force when the arm is opened and locked so that the opened arm is not easily closed.

  On the other hand, when the folding hanger is removed from the clothing, the arm is unlocked. However, if the unlocking operation itself is troublesome, the hanger cannot be removed smoothly from the clothing, and convenience is impaired. . Therefore, it is desirable that the folding hanger is capable of performing the unlocking operation by a simple one-touch operation such as a push button operation.

  The present invention has been made in view of the above-described problems, and has a sufficient holding force in a state where the arm is opened and locked, while being able to easily perform the unlocking operation and smoothly close the arm. The purpose is to provide an expression hanger.

  In order to solve the above problems, the present invention comprises the following means.

[1] The base end sides of both side arms are pivotally attached to both sides of the hanger body, and the both side arms are configured to be swingable between a state in which the both side arms are opened substantially horizontally and a state in which the arms are suspended and closed. On the other hand, a folding hanger provided with a locking mechanism for locking the hanger body in a state where the both side arms are opened,
The locking mechanism includes: a cross lever member that opens and closes so that intermediate portions of a pair of levers are pivotally attached to each other and upper ends and lower ends of the pair of levers are in contact with each other; and the cross lever member Biasing means for biasing in the direction of opening,

FIG. 10 is a front sectional view showing the periphery of the main body of a folding hanger as a modification of the present invention.

  1 to 5 are front sectional views showing a folding hanger according to an embodiment of the present invention. As shown in these drawings, the folding hanger of this embodiment includes a hanger body 1, a hook 2 attached to the upper end of the hanger body 1, and left and right both sides provided at both lower ends of the hanger body 1. Arms (a pair of arms) 3 and 3 and a lock mechanism 4 provided on the hanger body 1 are provided as basic components.

  The hanger body 1 has a substantially mountain shape with a circular arc at the apex, and is formed in a hollow structure with a hollow inside. Operation button openings 11 are formed on both upper side walls of the hanger body 1. Furthermore, the part from the lower end of the both sides of the hanger body 1 to the lower end is opened through the lower opening 12.

  The hook 2 is constituted by an integrally molded product of a synthetic resin including an arc-shaped hook body 21 that can be hooked on a clothesline and a mounting shaft portion 22 formed at the lower end of the hook body 21. The attachment shaft portion 22 is attached to the upper end wall of the hanger body 1 so as to be rotatable around the vertical axis.

  In the present embodiment, each arm 3 is configured such that a portion disposed on the hanger body 1 side is configured as a base end side (inside), and a portion disposed on the opposite side is configured as a distal end side (outside). Yes.

  On the proximal end side of the arm 3, an attachment portion 31 that is bent slightly downward is formed in the arm open state (see FIGS. 1 and 3). The position of the outer side (front end side) of the mounting portion 31 of the arm 3 is pivotally attached to the hanger body 1 via the shaft portion 35, and the outer side (front end side) of the arm 3 is the hanger main body. 1 is arranged in a state of being pulled out through the lower opening 12. Each arm 3 is configured to be rotatable about its shaft portion 35 as a fulcrum, and is opened substantially horizontally as shown in FIG. 1 (opened state) and vertically hangs down as shown in FIG. It can swing between the closed state (closed state).

  An arc-shaped curved portion 32 is formed below the edge of the mounting portion 31 of the arm 3, and when the arm 3 is opened by the curved portion 32 as will be described later, the lever of the lock mechanism 4 is 51 can be pushed in smoothly.

  The arm 3 has an auxiliary arm 36 that is slidable in the arm length direction. If necessary, the arm 3 can be extended by sliding the auxiliary arm 36 outward. ing.

  In the present embodiment, the attachment portion 31 of the arm 3 is configured as a proximal end portion.

  As shown in FIG. 6, the lock mechanism 4 is constituted by a synthetic resin integrally molded product including a cross lever member 5 and a spring member 6 as an urging means.

  The cross lever member 5 includes a pair (two) of levers 51 and 51. Each lever 51 has a “<” shape that is slightly bent at the intermediate portion, and the intermediate portions are pivotally attached to each other via a pivoting shaft portion 63 described later. As a result, the cross lever member 5 can be opened and closed by rotating in the direction in which the upper end portions and the lower end portions of the pair of levers 51 are close to each other (the closing direction) and in the separating direction (the opening direction). Yes. In the present embodiment, the upper end portion of the lever 51 constitutes one end portion, and the lower end portion constitutes the other end portion.

  On the outer side of the lower end portion of each lever 51, a concave step portion 52 that is recessed inward is formed, and the upper end wall (ceiling wall) of the concave step portion 52 is configured as a locking portion 53. Further, a cam surface 54 is formed above the concave step portion 52 on the lower outer side of each lever 51 so as to incline toward the outer side as it goes downward.

  In addition, operation buttons 55 that extend substantially vertically are integrally formed at the upper end of each lever 51. When the operation buttons 55 are pushed inward from both sides, the cross lever member 5 is closed.

  The spring member 6 provided so as to be bridged between the operation buttons 55 includes two (a pair of) spring pieces 61 and 61 each having an inverted U shape. The outer piece of each spring piece 61 is integrally connected and fixed to the inner side of the upper end of the corresponding operation button 55. Further, a fixed portion 62 is integrally formed between the inner pieces of the pair of spring pieces 61. The fixed portion 62 is integrally formed with a pivot shaft 63, and the shaft 63 is rotatably disposed at the intersection of the pair of levers 51 in the cross lever member 5, as described above. A pair of levers 51 are pivotally attached to each other via a pivotable shaft portion 63.

  Each spring piece 61 stores energy when elastically deforming the cross lever member 5 in the closing direction, and biases the cross lever member 5 in the opening direction by its elastic restoring force (biasing force). . That is, the cross lever member 5 is closed when the operation button 55 is pushed in from both sides. However, when the pushing force to the operation button 55 is released to make it free, the cross lever member is caused by the elastic restoring force of the spring piece 62. 5 opens to return to its open state.

  As described above, the lock mechanism 4 is constituted by an integrally molded product of synthetic resin, and before assembling immediately after molding, the pair of levers 51 are separated as shown in FIG. Then, from this state, one lever 51 intersects the other lever 51 and overlaps the front and rear, and the pivoting shaft portion 63 of the fixed portion 62 is rotatably passed through the intersecting portion of both levers 51. As a result, the lock mechanism 4 is assembled as shown in FIG.

  As shown in FIGS. 3 to 5, the assembled lock mechanism 4 is attached to the inside of the hanger body 1. That is, the lock mechanism 4 is disposed inside the hanger body 1 so that the operation buttons 55 on both sides face the operation button openings 11 on both sides of the hanger body 1, and in this state, the fixing portion 62 of the lock mechanism 4. Is fixed to the inner surface of the hanger body 1. As shown in FIGS. 2 and 4, the attachment portion 31 of the arm 3 is disposed outside the lower end portion of the lever 51 when the arm 3 is closed.

  In the foldable hanger configured as described above, when the arm 3 is lifted up so as to swing upward from the closed state as shown in FIGS. The portion 32 contacts the cam surface 54 of the lever 51, and the curved portion 32 of the arm 3 moves downward along the cam surface 54 while pushing the cam surface 54 inward. Thus, the lever 51 is rotated inward (in the closing direction) with its lower end pushed by the arm 3, while the spring piece 61 is compressed (accumulated) against the biasing force. When the base edge of the arm 3 comes out of the cam surface 54 of the lever 51 and reaches the concave step 52, the lever 51 is released from being pushed by the arm 3, and both levers 51 are elastically restored by the spring pieces 61. Thus, the upper end of the arm 3 is locked to the locking portion 53 of the lever 51. As shown in FIG. 1 and FIG. 3, this locking prevents the base end of the arm 3 from moving upward, that is, prevents the arm 3 from swinging in the closing direction. It is held (locked) horizontally.

  In this locked state, each arm 3 is inserted from a neck hole of clothing such as a T-shirt, and the T-shirt is suspended from both arms 3. In the suspended state, the hanger hook 2 is hooked on a clothesline or the like, so that the T-shirt can be dried.

  Here, in the foldable hanger of the present embodiment, a sufficient holding force can be ensured when the arm 3 is opened and locked, and even if a strong force acts in the direction of closing the arm 3, The lock will never be released unintentionally. That is, as shown in FIG. 3, in the foldable hanger of the present embodiment, in the locked state, the lower end portion (locking portion 53) of the lever 51 in the lock mechanism 4 suppresses the base end portion of the arm 3 from above and the lever Since the fulcrum 51 (the pivot shaft 62) is disposed above and inside the base end of the arm 3, a large downward load is applied to the distal end side (outside) of the arm 3, so that the arm 3 When trying to swing in the closing direction, the base end portion of the arm 3 tries to push up the lower end portion of the lever 51 and tries to rotate the lever 51 in the opening direction, that is, in the locking direction. Thus, when the arm 3 tries to close with a strong force in the locked state, the lever 51 tries to rotate in the locking direction, so that the locked state is reliably maintained and the lock is inadvertently released. Can be reliably prevented. Therefore, it is possible to prevent a problem that the arm 3 is closed due to inadvertent unlocking in a state where the garment is suspended, and it is troublesome to open the arm 3 again and hang the garment on the hanger. There is no need to perform any major work.

  On the other hand, as shown in FIG. 5, when the hanger is taken out from the T-shirt, the operation buttons 55 on both sides of the lock mechanism 4 may be pushed inward so as to be pinched from both sides with, for example, the thumb and forefinger. Thereby, the cross lever member 5 is closed against the urging force of the spring member 6, and the locking portion 53 of the lever 51 is retracted inward from the upper side of the base end portion of the arm 3. Thus, the lock of the arm 3 in the horizontal state is released, and the arm 3 swings downward (closed direction) by its own weight and is closed.

  As shown in FIG. 4, even when the push on the operation button 55 in the lock mechanism 4 is released and the cross lever member 5 is opened with the arm 3 closed, the base end portion of the arm 3 remains on the lever 51. Since they are arranged on the side of the lower end, they do not interfere with each other, and the arm 3 is maintained in a suspended state (closed state).

  As described above, according to the foldable hanger of the present embodiment, a sufficient holding force in a state where the arm 3 is opened and locked can be sufficiently secured, so even if a strong force acts in the direction of closing the arm 3, It is possible to reliably prevent a problem that the arm 3 closes carelessly.

  Further, in a state where the arm 3 is opened and locked, the lock can be released by a simple operation of pushing the operation button 55 of the lock mechanism 4 inward, and the arm 3 can be smoothly closed.

  Further, according to the folding hanger of the present embodiment, since the lock mechanism 4 is constituted by an integrally molded product, that is, a single article, the lock mechanism 4 itself can have sufficient strength, and malfunction due to breakage or the like occurs. Can be reliably prevented, and high reliability and sufficient durability can be obtained. Furthermore, the number of components of the folding hanger can be reduced, and the cost can be reduced.

  In the present embodiment, the cross lever member 5 that constitutes a part of the lock mechanism 4 is a rotary lever system in which the intermediate portions of the pair of levers 51 are pivotally attached to each other, so that the opening / closing operation is always performed in a stable state. Is called. For this reason, the operation | movement at the time of the lock mechanism 4 at the time of locking and unlocking is performed accurately and smoothly, and a high quality hanger product with high operation reliability can be provided.

  Furthermore, in this embodiment, since the shaft part 63 (fixing part 62) of the lever 51 in the cross lever member 5 is fixed to the hanger body 1, the lever 51 can be rotated in a more stable state, and further operation is performed. Reliability can be improved.

  In addition, since the distance from the rotation fulcrum (shaft portion 63) of the lever 51 to the lower end portion (operation point) can be shortened, the bending of the lever itself is reduced, and the rotation operation of the lever 51 can be reliably transmitted to the arm 3. At the same time, the rotational movement of the arm 3 can be reliably transmitted to the lever 51, and the operational reliability can be further improved.

  Further, in the present embodiment, the fixing portion 62 of the locking mechanism 4 is not displaced regardless of the rotation operation of the lever 51 or the expansion and contraction operation of the spring piece 61. Therefore, by fixing the fixing portion 62 to the hanger body 1, the locking mechanism 62 4 can be securely fixed without adversely affecting its operation or the like.

  FIG. 8 is a front sectional view of a peripheral part of a main body of a folding hanger as a modification of the present invention, and FIG. 9 is a front view for explaining a lock mechanism 4 employed in the folding hanger of the modification.

  As shown in both figures, in the foldable hanger of this modification, the lock mechanism 4 is composed of two parts, which is different from the foldable hanger of the above embodiment.

That is, as shown in FIG. 9, the lock mechanism 4 in the foldable hanger according to this modification is formed by assembling two members, a first lock member 41 and a second lock member 42 , each composed of a synthetic resin integral molded product. Is formed. The first and second lock members 41 and 42 include a lever 51 and an operation button 55, respectively. Further, the first and second lock members 41, 42 include a substantially semicircular arc-shaped spring piece 61 opened substantially downward, and the outer piece of each spring piece 61 is connected and fixed to the upper end portion of the operation button 55. At the same time, fixing pieces 621 and 621 are integrally formed on the inner piece of each spring piece 61.

  As shown in FIG. 8 and FIG. 9, in this locking mechanism 4, when one fixing part piece 621 is overlapped and fixed to the other fixing part piece 621 in the front-rear direction, the fixing part 62 is formed. At the same time, the first and second lock members 41 and 42 are connected to each other. In this connected state, one lever 51 is further overlapped on the other lever 51 so as to intersect with the other lever 51, and a pivoting shaft portion 63 formed on the fixing portion 62 is formed at the intersection of both levers 51. The lock mechanism 4 according to this modified example is assembled by being disposed so as to be freely rotatable.

  The assembled lock mechanism 4 is assembled to the hanger body 1 in the same manner as in the above embodiment.

  In the foldable hanger of this modified example, the other configuration is substantially the same as that of the foldable hanger of the above-described embodiment.

  The foldable hanger of this modification also has the same operational effects as in the above embodiment. For example, since the fulcrum of the lever 51 is disposed above and inside the base end of the arm 3, even if a strong force acts in the direction of closing the arm 3 in a state where the arm 3 is opened and locked, the lever 51 tries to rotate in the locking direction. For this reason, it is possible to secure a sufficient holding force in a state where the arm 3 is horizontally locked, and it is possible to prevent a problem that the lock is inadvertently released. Further, when the arm 3 is opened and closed from the locked state, the arm 3 can be easily closed simply by pushing the operation button 55 of the lock mechanism 4 inward.

  In the above embodiment, a ring-opening type hook is used as the hook 2, but the hook type is not limited in the present invention. For example, in the present invention, a pinch type hook that sandwiches and holds a clothes basket or the like, or a hook that is provided with a stopper for preventing opening and closing at the ring opening portion can be used.

  Furthermore, in the present invention, it is not necessary to form a hook or the like directly on the hanger body 1. For example, as shown in FIG. 10, the present invention is a multi-array type folding type in which the upper end of the hanger body 1 is formed in a U shape and the mounting shaft portion 26 is formed outside the upper end of both side pieces 25. It can also be used for hangers. This multi-array foldable hanger is supported by a groove-type support member opened downward. For example, in a state where a large number of folding hangers are arranged at regular intervals in the front-rear direction, the upper ends of both side pieces 25 of each hanger are respectively accommodated in the grooves of the groove-type support member, and the mounting shafts of the hangers The portions 26 are rotatably supported on both side walls of the groove type support member. A large number of folding hangers are suspended through the groove-type support member by hooking the hook provided on the groove-type support member on a clothesline or the like.

  In the above-described embodiment and the like, the spring member 6 is bridged between the upper ends of both levers 51 in the lock mechanism 4. However, the present invention is not limited to this, and in the present invention, both levers 51 are closed when both levers 51 are closed. The installation position of the urging means is not limited as long as the urging means can be urged in the opening direction. For example, an urging means such as a spring member may be provided between the lower ends of both levers.

  Further, in the above-described embodiment and the like, an inverted U-shaped wire processing spring is used as the biasing means, but in the present invention, the configuration of the biasing means is not limited. For example, biasing means such as a coil spring, a torsion coil spring, and a thin plate spring may be used.

  The foldable hanger according to the present invention can be used when clothes or the like are suspended and dried or stored.
