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

In addition, the upper surface of the collar iron buck 2 is set such that the right and left position 2b corresponding to both ends of the collar 1a in its longitudinal direction are formed into a horizontal surface. As shown in
In addition, in the case of the present invention, the upper surface of the collar iron buck 2 are formed such that they may be fallen into the flat surface shape when they are pressed with the press iron 3. Reference numeral 8 denotes a first coil spring acting as a resilient member for supporting the right and left position 2b of the collar iron buck 2. The first coil springs are arranged at the terminal ends of the horizontal plate 6, outwardly fitted to a raised first metallic rod 9 (refer to
In addition, reference numeral 13 (refer to

Then, an action of the present invention in accordance with this preferred embodiment will be described as follows.
At first, the operator sets the cuff 1b of the shirt 1 to the cuff iron buck 19 as shown in
Then, as shown in
In this case, a resilient pressure of the resilient member 8 in the present invention is selected to be larger than a resilient pressure of the resilient member 13. Accordingly, in accordance with the present invention, at first, the press iron 3 fixes the right and left ends of the collar 1a and presses the collar 1a while expanding it in a lateral direction.
In addition, when the press iron 3 makes the upper surface of the collar iron buck 2 fall, the upper surface of the collar iron buck 2 abuts against the heat transfer portions 16 and then the upper surface of the collar iron buck 2 is heated by the heat transfer portions 16. As a result, the collar 1a is applied with heat from above by the press iron 3 and from below by the upper surface of the collar iron buck 2 and then the collar is press finished fast and neatly.
Thus, in the present invention, when the press iron 3 depresses against the collar iron buck 2, the press pressure is also added to the cuff iron buck 19 (refer to
With such an arrangement as above in the present invention, it is also applicable that the cuff iron buck 19 is eliminated. In addition, also when the cuff iron buck 19 is installed to form the present invention, the buck is not limited to the lower side of the collar iron buck 2, but the bucks can be arranged at both sides of the collar iron buck 2 in the same manner as that of this type of prior art finishing machine. In addition, it may also be applicable that the collar iron buck 2 is constructed such that the resilient members 8, 13 are 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 position 2a of the collar iron buck 2 is formed narrow and the collar 1a can 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.
