BACKGROUND OF INVENTION

1. Field of Invention

This invention relates to a shirt finishing machine for use in press finishing a shirt such as a washed white shirt and the like, and more particularly a shirt finishing machine having a collar extending function for extending neatly the collar shrunk through its washing to enable it to be press finished.

2. Description of Related Art

As this type of prior art shirt finishing machine, there has been provided the machine described in the gazette of U.S. Pat. No. 7,000,340, for example. This type of prior art shirt finishing machine is formed such that the upper surface position of a collar iron buck where the collar of a shirt is extended wide in a lateral direction is notched in an inverse triangular shape as seen from its front elevational view, the collar at its lateral position communicating with this upper surface position and corresponding to both ends of the collar in its longitudinal direction is formed into a horizontal surface, and when the upper surface of the collar iron buck is pressed with the press irons, it is fallen into a flat surface shape.

In such a case as above, this type of shirt finishing machine is operated to depress the collar into a flat surface by a press iron having a flat iron surface and a collar iron buck fallen into a flat surface state through a pressing operation of this press iron.

However, the prior art machine has been constituted in such a way that the upper surface of the color iron buck is supported by a coil spring under the same spring pressure state for entire upper surface. Due to this fact, when the press iron pressed against the upper surface of the collar iron buck, the collar was held and fixed at the horizontal lateral position of the collar iron buck and the iron surface of the press iron and the upper surface of the iron buck was fallen. Accordingly, in accordance with the prior art machine, the location of the collar corresponding to the inverse-triangular shaped upper surface position of the collar iron buck was pulled in a lateral direction and the entire collar could not be pulled and extended in a lateral direction under a well-balanced state.

The present invention has been provided in view of some prior art problems as described above.

Accordingly, the technical themes to be solved by the present invention provide a shirt finishing machine having a collar expanding function in which the collar iron buck is fallen into a flat surface shape position through the pressing operation of the press iron and the collar is press finished into a flat surface shape, and the collar is expanded in the same rate over its entire length and the collar can be neatly press finished.

SUMMARY OF INVENTION

The present invention is formed to be provided with a collar iron buck for use in laterally expanding a collar of a shirt and putting it on the collar iron buck, and a press iron for pressing against the upper surface of the collar iron buck to, press finish the collar. The upper surface position of the collar iron buck corresponding to the longitudinal central part of the collar is notched in an inverse triangular shape as seen from the front view. The lateral position communicated with the upper surface position and corresponding to both ends of the collar in the longitudinal direction are formed into a horizontal surface and when the upper surface of the collar iron bucks are pressed by the press iron, they are fallen into a flat surface. In addition, the iron surface of the press irons are formed into a flat surface. In such a shirt finishing machine as described above, the present invention is set such that a resilient pressure of a resilient member supporting the lateral position of the collar iron is selected to be larger than a resilient pressure of the resilient member supporting the upper surface position of the inverse-triangular shape of the collar iron bucks.

Since the present invention is constituted as described above, when the press irons press against the upper surface of the collar iron bucks, lateral ends of the collar are fixed, the collar can be extended in a lateral direction under this state as the collar iron bucks are fallen, and can be press finished.

Accordingly, in accordance with the present invention, both the front side and rear side of the collar shrunk by its washing can be extended over an entire lateral direction of the collar and the collar can be finished clean.

The expression of “can be formed into a flat surface and fallen” is meant by the fact that when the upper surface of the collar iron buck receives a pressing force by the press iron, it is fallen into a flat surface and as the pressing force is removed, it is recovered. As the resilient member, there may be applied such as a compressed coil spring, leaf spring, damper and rubber or the like, for example. Although the resilient member for supporting the lateral position of the collar iron buck is usually arranged at the end part of the collar iron buck, it may also be applicable that it can be arranged at a position near more inwardly than the end part of the collar iron buck in correspondence with the lateral ends of the collar. In addition, the resilient member for supporting the upper surface position of the inverse-triangular shape of the collar iron buck is arranged just below the upper surface position or the position of an interface between the upper surface position and the lateral position, for example. In this case, the resilient pressure is meant by a recovering force in which the spring returns back to its original state when the coil spring is compressed with the pressing force of the press iron and deformed. As a difference between the resilient members, it may be properly selected in compliance with some characteristics such as the type or thickness of collar cloth and extending or shrinkage of the collar caused by its material quality and the like.

Thus, it is preferable for the present invention to be formed such that the lateral position of the upper surface of the collar iron buck is received when this upper surface is fallen and at the same time there is provided a protruded step heat transfer part for transmitting heat to the upper surface to heat it.

Because, with this arrangement as above, when the press iron is fallen onto the upper surface of the collar iron buck, heat is applied to the collar from above and below in cooperation with the press iron and the collar can be press finished rapidly and neatly. The heat transferring part is usually formed in such a way that steam is supplied inside the heat transferring part and the heat of steam is transferred to the upper surface of the collar iron buck. However, the heat transferring part is not limited to such a configuration as above, but it may be formed such that the heater is stored in it, for example. In addition, in case of the present invention, a forming position, number and shape of the heat transferring part as seen from its top plan view or the like can be set as features that are properly selected.

In addition, the shirt finishing machine of the present invention can be applied as one in which the upper surface of the collar iron buck is covered by a mat-like cover in which the resilient surface member of resin or rubber is covered by cloth, and the lower surface position of the resilient surface member corresponding to the inverse triangular-shaped upper surface position of the aforesaid collar iron buck and the resilient surface member is abutted against the lateral position of the horizontal surface of the collar iron buck.

The cover covering the upper surface of collar iron buck in the prior art was formed to cover the entire resilient surface member with a cloth. Due to this fact, there occurred a situation in the past that when the press iron presses against the upper surface of the collar icon buck, the resilient surface member was pulled or locally shrunk, for example, due to a difference in coefficient of friction between the cloth and the resilient surface member and a bad influence was applied to the finishing of the collar. The present invention can resolve such problems as above. Because, in case of the present invention, the resilient surface member can be extended freely in correspondence with the falling operation of the upper surface of the collar iron buck while it is being held with a cloth at a position corresponding to the inverse triangular-shaped upper surface position of the collar iron buck. It is satisfactory that the resilient surface member is a resilient sheet-like or mat-like member and more practically it may be made of silicone rubber or synthetic rubber and elastomer and the like.

In addition, it is preferable that the shirt finishing machine of the present invention is constituted such that the inverse triangular-shaped upper surface position of the collar iron buck is formed by a pair of right and left plates, the pivoted ends of the pair of right and left plates are formed into a rectangular wave shape as seen from a top plan view, the pair of right and left plates cause the convex end part and concave end part to be engaged to each other and they are connected at the pivot shaft.

Because, in accordance with this arrangement, a length of the clearance formed at the connected location of a pair of right and left plates and extending in a forward and rearward direction of it as seen from its top plan view can be shortened and the press pressure can be dispersed more as compared with the case that of this type of long clearance. Further, in this case, it is possible to reduce a trace of iron placed at the central part of the collar.

DESCRIPTION OF PREFERRED EMBODIMENTS

Referring now to the drawings, the preferred embodiments of the present invention will be described.

As shown inFIG. 1or the like, the shirt finishing machine of the present invention is formed to comprise a collar iron buck2in which a collar1aof a shirt1is extended laterally and mounted on it and a press iron3for pressing collar1aagainst the upper surface of the collar iron buck2. An iron surface of the press iron3is formed into a flat surface.

As shown inFIGS. 5 and 6, the upper surface position2aof the collar iron buck2corresponding to the central part of the collar1ain its longitudinal direction is set such that a pair of right and left plates4are pivotally connected at a pivot shaft5and they are formed into an inverse triangular shape as seen from its front elevational view. The ends4aat the side of the pivoted portions of the pair of right and left plates4are formed into a rectangular wave shape as seen from their top plan view, the pair of right and left plates4are connected by the pivot shaft5to each other while the convex portions and concave portions of the ends4aare being engaged to each other.

In addition, the upper surface of the collar iron buck2is set such that the right and left position2bcorresponding to both ends of the collar1ain its longitudinal direction are formed into a horizontal surface. As shown inFIGS. 5 and 6or the like, the pair of right and left plates4are pivoted at their side ends to the horizontal plates6forming the right and left position2bin the upper surface of the collar iron buck2through joint shafts7.

In addition, in the case of the present invention, the upper surface of the collar iron buck2are formed such that they may be fallen into the flat surface shape when they are pressed with the press iron3. Reference numeral8denotes a first coil spring acting as a resilient member for supporting the right and left position2bof the collar iron buck2. The first coil springs are arranged at the terminal ends of the horizontal plate6, outwardly fitted to a raised first metallic rod9(refer toFIG. 8or the like), the lower part of the first metallic rod9is inserted into a first supporting rod10in such a way that the rod can be moved up and down, and its removal is stopped by a nut11. In addition, the upper end of the first metallic rod9is pivoted to the horizontal plate6through a lateral shaft12extending in a forward and rearward direction.

In addition, reference numeral13(refer toFIG. 8or the like) denotes a second coil spring acting as a resilient member for supporting the inverse triangular-shaped upper surface position2aof the collar iron buck2. This second coil spring is outwardly fitted to an inclined second metallic rod15connected to a joint block7aand arranged between the joint block7aof the joint shaft7and the second supporting rod14laterally installed along a forward or rearward direction of the collar iron buck2. The lower part of the second metallic rod15is inserted into the second supporting rod14in such a way that it may be moved up and down and its removal is stopped by the nut11. Then, a resilient pressure of the first coil spring acting as the resilient member8is selected to be larger than a resilient pressure of the second coil spring acting as the resilient member13for use in supporting the inverse triangular-shaped upper surface position2aof the collar iron buck2.

Reference numeral16(refer toFIGS. 5 to 7or the like) denotes convex-stepped heat transfer segments for receiving the right and left position2bof the upper surface when the upper surface of the collar iron bucks2are fallen and transferring heat to the upper surface to heat them. The heat transfer segments16are arranged below the upper surface position2aand the right and left position2b. In addition, in case of this preferred embodiment, the heat transferring segments16are formed into a rectangular block shape as seen from its top plan view and steam is supplied into it.

Thus, the upper surface of the collar iron buck2is covered by the mat-like cover17. This cover17in this preferred embodiment is formed such that the resilient surface member17a(refer toFIGS. 11 to 13or the like) of silicone rubber is covered by a cloth17b. The lower surface position of the resilient surface member17acorresponding to the inverse triangular-shaped upper surface position2aof the collar iron buck2is enclosed by the aforesaid cloth17b. Then, the resilient surface member17ais arranged such that it is directly struck against the horizontal surface right and left position2bof the collar iron buck2. In addition, the resilient surface member17ahas many holes17a1passing through it in an upward or downward direction.

In this preferred embodiment, the cover17is formed such that the upper side of the resilient surface member17ais provided with a flannel surface member17c(refer toFIG. 13). Then, as shown inFIG. 1A, the cover17is fixed in tension to the upper surface of the collar iron buck2by a method wherein the cloth17bis pulled downward by the pulling member18at the central forward or rearward position or both side position or the like of the collar iron buck2.

Reference numeral19(refer toFIGS. 1A and 2or the like) denotes an iron buck for a mountain-shaped cuff for use in setting a cuff1bof the shirt1. A pair of right and left iron bucks19for cuff are arranged below the collar iron buck2. In addition, reference numeral20denotes an iron part for pressing against the upper surface of the cuffs iron buck19. This iron part20is formed at the lower surface of the collar iron buck2while being concaved in a mountain-shaped in an upward direction. The collar iron buck2is formed such that it may be turned in an upward or downward direction around the fulcrum point22through an extending or retracting operation of the rod in the cylinder device21(refer toFIG. 3) arranged to be raised.

In addition, reference numeral23inFIG. 3denotes an operating cylinder for the press iron3. When the rod in the operating cylinder23is extended, the press iron3is turned around the pivoted part25through the link mechanism24in an upward or downward direction to depress against the collar iron buck2and at the same time to depress the lower side cuff iron buck19through the collar iron buck2.

Then, an action of the present invention in accordance with this preferred embodiment will be described as follows.

At first, the operator sets the cuff1bof the shirt1to the cuff iron buck19as shown inFIG. 1A. Then, the operator depresses a start button. Then, the rod in the cylinder device21(refer toFIG. 3) is retracted, the collar iron buck2descends and the iron part20depress against the cuff iron buck19.

Then, as shown inFIG. 1B, the operator expands the collar1aof the shirt1laterally onto the upper surface of the collar iron buck2and sets the collar. Then, the operator depresses the switch. Then, the rod in the operating cylinder23(refer toFIG. 3) extends and the press iron3turns around the pivoted part25in a downward direction. Then, when the press iron3depresses against the upper surface of the collar iron buck2against a resilient force of the resilient members8,13(refer toFIG. 9), the pair of right and left plates4are lowered, turned around the pivot shaft5and pushed down, the horizontal plates6at the right and left position2bcorresponding to both ends of the collar1aare gradually depressed down while moving slightly in an outward direction, and finally the plates4and the horizontal plates6are fallen into a flat surface state (refer toFIG. 10).

In this case, a resilient pressure of the resilient member8in the present invention is selected to be larger than a resilient pressure of the resilient member13. Accordingly, in accordance with the present invention, at first, the press iron3fixes the right and left ends of the collar1aand presses the collar1awhile expanding it in a lateral direction.

In addition, when the press iron3makes the upper surface of the collar iron buck2fall, the upper surface of the collar iron buck2abuts against the heat transfer portions16and then the upper surface of the collar iron buck2is heated by the heat transfer portions16. As a result, the collar1ais applied with heat from above by the press iron3and from below by the upper surface of the collar iron buck2and then the collar is press finished fast and neatly.

Thus, in the present invention, when the press iron3depresses against the collar iron buck2, the press pressure is also added to the cuff iron buck19(refer toFIGS. 1A and 2). Accordingly, the iron part20depress against the cuffs1b, and the collar1aand cuffs1bare concurrently press finished.

With such an arrangement as above in the present invention, it is also applicable that the cuff iron buck19is eliminated. In addition, also when the cuff iron buck19is installed to form the present invention, the buck is not limited to the lower side of the collar iron buck2, but the bucks can be arranged at both sides of the collar iron buck2in the same manner as that of this type of prior art finishing machine. In addition, it may also be applicable that the collar iron buck2is constructed such that the resilient members8,13are composed of a leaf spring or a damper and the like and freely fallen into a flat state.

The shirt finishing machine of the present invention is constituted such that the lateral width of each of the inverse triangular-shaped upper surface position2aof the collar iron buck2is formed narrow and the collar1acan be set without requiring any receiving plate already described in the Patent Document 1. Accordingly, in accordance with the present invention, it is possible to eliminate the receiving plate or the receiving plate removal mechanism of the prior art machine and correspondingly the product can be provided in less-expensive price.
