1. Field of the Invention
The present invention relates to a presser used in handicraft for holding and/or moving, e.g., a sheet-like material such as cloth or fabric.
2. Description of the Related art
Conventionally, use has been made of a cloth presser for moving a piece of cloth being sewn with a sewing machine. For example, JP Design Registration No. 777801 discloses a prick punch that can be used as a cloth presser. The conventional prick punch disclosed in the document includes a metal extension extending from the grip portion. The extension has a sharp-pointed tip.
In use, the cloth is lightly held down with the tip of the extension, and the tip is moved in the desired direction to move the cloth. The tip of the extension, however, tends to slip on the cloth due to the small area of contact, which is not preferable for moving the cloth properly.
The present invention has been proposed under the circumstances described above. Thus, it is an object of the present invention to provide a suitable presser for cloth or fabric, for example, whereby the use can properly move a sheet-like object in a desired direction.
According to an embodiment of the present invention, there is provided a cloth presser that includes: an elongated grip portion having a straight longitudinal axis; and a first press end and a second press end spaced apart from each other with the grip portion intervening between the first press end and the second press end. The first press end is configured to make point contact with cloth, and the second press end is configured to make surface contact with the cloth.
Preferably, the first press end includes a pointed tip, and the second press end includes a flat surface softer than the first press end.
Preferably, the cloth presser further includes a tapered extension extending from the grip portion. The extension has a curved central axis, and the first press end is provided at an end of the extension.
Preferably, the second press end is slanted with respect to the longitudinal axis of the grip portion, and the second press end is smaller in area than the maximum cross section of the grip portion.
Preferably, the second press end has a normal line contained in a plane containing the central axis of the extension. The second press end faces a region in which the extension is disposed with respect to the longitudinal axis of the grip portion.
Preferably, the cloth presser further includes: a shaft extending from the grip portion in parallel to the longitudinal axis of the grip portion; and a cap attached to the shaft. The shaft is smaller in diameter than the grip portion, the cap has an outer surface connected smoothly to an outer surface of the grip portion, and the second presser end is disposed at the cap.
Preferably, the cap is formed with a hole into which the shaft is fitted, the shaft includes an inclined end surface generally parallel to the second press end, and the hole includes a bottom surface configured to make surface contact with the inclined end surface.
Preferably, the grip portion, the extension and the shaft are made of a first resin, and the cap is made of a second resin that is softer than the first resin.
Preferably, the first resin and the second resin are a thermosetting resin.
Other features and advantages of the present invention will become more apparent from detailed description given below with respect to the accompanying drawings.
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
The grip portion 1 is a bar-shaped member made of e.g., a hard thermosetting resin, and has a straight axis O1 extending in the x1-x2 direction. The grip portion 1 is the part to be gripped by a user, and has a circular cross section over its entire length. Along the x1-x2 direction, the grip portion 1 includes a central part 1a (whose cross-sectional area is constant) and two end parts 1b connected to the central part 1a at its respective ends. Each end part 1b is configured to taper with increasing distance from the central part 1a. It should be noted that the present invention is not limited to such an arrangement. The grip portion 1 may be configured to have a non-constant cross-sectional area. In this instance, the grip portion 1 may be tapered from the longitudinal center toward the respective ends.
The first press end 100 is spaced apart from the grip portion 1 in the x1 direction, and is formed as a hard, sharp-pointed tip. As readily seen, the first press end 100 is capable of making point contact with a piece of cloth, for example. The second press end 200 is spaced apart from the grip portion 1 in the x2 direction, and is formed as a relatively soft, flat surface. Thus, the second press end 200 is capable of making surface contact with a piece of cloth, for example. In other words, the second press end 200 has a greater contact area than the first press end 100.
As seen from
As shown in
The extension 10 has a curved central axis O2. The extension 10 is configured to taper along the central axis O2 with increasing distance from the grip portion 1. The extension 10 is made of the same hard thermosetting resin as the grip portion 1. The first press end 100 is formed at the tip of the extension 10.
As shown in
The above-mentioned grip portion 1, extension 10 and shaft 20 are formed integral with each other with a hard thermosetting resin. Examples of such a thermosetting resin are melamine resin and an urea formaldehyde resin.
As shown in
The cap 21 is made of a thermosetting resin which is softer than the hard thermosetting resin mentioned above. An example of such a soft thermosetting resin is a thermosetting elastomer that exhibits rubber-like elasticity. Alternatively, use may be made of silicone rubber, (poly)urethane rubber or fluorocarbon rubber.
The cap 21 is detachably attached to the shaft 20. As shown in

A method of how to use the cloth presser A and its advantages will be described with reference to
The cloth presser A is provided with the first press end 100 and the second press end 200 that are spaced from each other in the longitudinal direction of the grip portion 1. The first press end 100 is configured to hold the cloth by point contact, while the second press end 200 is configured to hold the cloth by surface contact. Either of the first press end 100 and the second press end 200 can be selected for use, depending on the situation as described below.
In use, the user may hold the grip portion 1, and as shown in
The second press end 200 is slanted to the longitudinal axis O1 of the grip portion 1. As a result, the grip portion 1 inclines at a suitable angle to the vertical direction when the second press end 200 is pressed onto the cloth C. Hence, it is convenient for the user to hold the grip portion 1.
The cap 21 is configured to taper, and the second press end 200 is provided at the tip of the cap 21. With such an arrangement, the user can readily recognize the position of the second press end 200 when using the presser, and hence bring the second press end 200 to a desired part of the cloth C accurately. Since the cap 21 is made of a relatively soft resin, the second press end 200 is soft. Accordingly, the frictional force generated between the cloth C and the second press end 200 is great enough to move the cloth C as required.
The cap 21 is attached to the shaft 20 by fitting the shaft 20 into the hole 210. As shown in
The cross section of the shaft 20 and the cross section of the hole 210 have the same polygonal shape. Thus, the outer peripheral surface of the shaft 20 makes surface contact with the hole 210, and it is easy to position the cap 21 about the shaft 20. The cap 21 does not unduly turn about the shaft 20 once they are positioned relative to each other around the axis of the shaft 20. In the illustrated example, the small-diameter portion 201 of the shaft 20 and the circular engagement portion 211 of the cap 21 come into engagement with each other. Thus, the cap 21 does not come off the shaft 20 unduly.
In use of the cloth presser A, the first press end 100 can be used, as shown in
The extension 10 is made of a thermosetting resin. Thus, the extension 10 (hence the first press end 100) offers excellent resistance to high temperatures. The extension 10 extends from the grip portion 1 along the curved central axis O2. With this arrangement, the grip portion 1 inclines when the cloth is held with the first press end 100, whereby the user can comfortably hold the grip portion 1. Also, as shown in
As shown in
While a preferred embodiment of the present invention has been described using specific terms, such description is for illustrating purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
