Abstract

The present invention relates to a sleeve tightening device. In outerwear such as jumpers, it is necessary to adjust the sleeve according to the thickness of the wearer's wrist. In particular, in order to control the escape of warm air through the sleeve, it is preferable for the sleeve to adhere closely to the wearer's wrist. To this end, the present invention includes a tightening band (37) that tends to unfold when rolled into a circle, and an elastic member (47) that elastically secures one side of the tightening band (37) to a frame (39), thereby allowing the sleeve to be tightened or loosened relative to the wearer's wrist by the tightening band (37).

Description

Sleeve tightening device

The present invention relates to a sleeve tightening device.

A loose-fitting, easy-to-move outerwear is called a jumper. Jumpers are worn in cold environments, and the term is often used interchangeably with parkas and padded jackets. In other words, the term "jumper" is often used interchangeably with "parka," "padded jacket," and "jumper." Here, the term "jumper" will be used to refer to any loose-fitting, easy-to-move outerwear.

Jumpers have sleeves at the ends of both arms. Typically, the sleeves are designed to fit snugly around the wearer's wrists. This is to prevent the hands from being exposed outside the arms, even if the arms are long, hindering movement. It also prevents air from flowing between the inside and outside of the jumper through the loose sleeves.

A prior art technique for adjusting the length of the arms of an upper garment is presented in prior art document 1. However, prior art document 1 has the problem that the loops at both ends of a rubber band are connected to each other, requiring the wearer to operate the device with only one hand, making the task of connecting the loops cumbersome.

Furthermore, to prevent airflow between the inside and outside of a jumper, conventional technology involves placing elastic material within the sleeves, ensuring that the sleeves always adhere tightly to the wearer's wrists. However, with prolonged use, the elastic material loses its elasticity and ceases to function properly. Furthermore, the constant contact of the sleeves with the wearer's wrists can sometimes cause the wearer to feel uncomfortable, and if the elasticity is too great, it can hinder blood circulation in the hands.

To tighten sleeves around the wrist, multiple buttons and buttonhole pairs, or even a length of Velcro, can be used. However, inserting the buttons into the buttonholes is cumbersome, and even when using Velcro, it's relatively difficult to manipulate. Furthermore, foreign matter often adheres to the Velcro, making it inconvenient to use.

The purpose of the present invention is to solve the problems of the prior art as described above, and to enable the sleeves to be tightened and loosened in a one-touch manner.

An object of the present invention is to prevent the components for tightening and loosening the sleeve from being exposed to the outside of the sleeve.

In order to achieve the aforementioned objective, the present invention utilizes an elastic member to press down on a drawstring that tends to unfold when rolled into a circle, thereby controlling the degree of unfolding. Accordingly, the sleeve can be adjusted to fit and release the wearer's wrist by manipulating the elastic member and drawstring.

The present invention relates to a sleeve tightening device for tightening and loosening a sleeve formed by an inner lining and an outer lining of a sleeve in an arm portion, the device comprising: a tightening band that is positioned in a circular shape in a space formed between the inner lining and the outer lining of the sleeve and has a tendency to unfold when rolled into a circular shape; a frame through which one side of the tightening band passes and which is fixedly installed in the space between the inner lining and the outer lining of the sleeve; an elastic member that is installed in the frame and presses one side of the tightening band against the frame with elastic force; and a button that is installed on the outside of the frame and operates the elastic member to operate the force with which the elastic member presses the tightening band. The tightening band has one end fixed to the frame and the other end freely movable, and the other end can be rolled into a circular shape by passing through the frame, passing over the other end of the tightening band, and overlapping in a predetermined area.

The above tightening belt may have a friction layer formed on the outer surface that exerts frictional force.

The above friction layer may be formed by coating a material having a high coefficient of friction on at least one of the front and back surfaces of the tightening band, or by attaching a fabric to at least one of the front and back surfaces of the tightening band.

The above frame includes a first plate, a second plate positioned parallel to the first plate, and a connecting plate connecting the first plate and the second plate, and an elastic member fixing portion for fixing the elastic member and a tightening belt hole through which the tightening belt passes may be formed in the connecting plate.

The above sleeve outer shell may further include a fixing piece to which the frame is fixed.

Between the button and the frame, a button elastic member may be provided that provides elasticity in a direction in which the button is separated from the elastic member.

The retail tightening device according to the present invention may have at least one of the following effects.

In the present invention, the degree to which a drawstring is rolled is controlled by pressing one side of a drawstring that tends to unfold when rolled into a circle using an elastic member. In particular, by pressing the drawstring, the drawstring is rolled, tightening the sleeve, and this tightened state is maintained by pressing one side of the drawstring by the elastic member. In addition, when the state in which the drawstring is pressed by the elastic member is released, the drawstring is released, releasing the sleeve, thereby releasing the tightened sleeve. In other words, in the present invention, the sleeve can be tightened and loosened in a one-touch manner.

Furthermore, in the present invention, the components for tightening and loosening the sleeves are all located between the sleeve lining and sleeve outer coverings that constitute the sleeves. Therefore, the sleeve tightening device is not exposed to the outside, thereby preventing it from being affected by the external environment.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When designating components in each drawing, it should be noted that, where possible, identical components will be given the same reference numerals, even if they appear in different drawings. Furthermore, when describing embodiments of the present invention, if a detailed description of a related known structure or function is deemed to hinder understanding of the embodiments of the present invention, such detailed description will be omitted.

Additionally, terms such as first, second, A, B, (a), (b), etc. may be used to describe components of embodiments of the present invention. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms. When it is described that a component is "connected," "coupled," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.

The drawings illustrate preferred embodiments of a sleeve tightening device according to embodiments of the present invention. As illustrated in FIG. 1, the sleeve tightening device of the present invention is located within a sleeve (30) at the end of the arm portion (20) of a jumper (10). The sleeve (30) may be formed in a cylindrical or oval cylindrical shape. The sleeve (30) is generally positioned to correspond to the wearer's wrist.

In Fig. 2, the sleeve (30) is designed to have a roughly oval cylindrical shape. The sleeve (30) includes a sleeve lining (31) and a sleeve outer covering (33). A space (35) is formed between the sleeve lining (31) and the sleeve outer covering (33). The space (35) is actually a very narrow area. That is, the sleeve lining (31) and the sleeve outer covering (33) have surfaces that face each other adjacent to each other. The space (35) is circular or oval. The sleeve lining (31) and the sleeve outer covering (33) may each have pleats. That is, pleats may be provided according to the degree to which the sleeve (30) is tightened or loosened.

There is a tightening band (37) within the above space (35). The tightening band (37) has a predetermined width and a very long length compared to the width. The tightening band (37) is made of a material that tends to unfold when rolled into a circle. An example of the material constituting the tightening band (37) may be a synthetic resin. That is, a synthetic resin film has a predetermined thickness and is shaped like a band to create the tightening band (37). When the tightening band (37) is rolled into a circle of a predetermined length, it can easily become a cylinder. In this state, the tightening band (37) may have a tendency to return to (unfold) its original state.

The above-described tightening belt (37) may be fixed at one end to the first plate (39') of the frame (39). The other end of the tightening belt (37) is positioned in the space (35) between the sleeve lining (31) and the sleeve outer covering (33) so as to be freely movable. The length of the tightening belt (37) should be such that it can wrap around the sleeve (30) at least once. As can be seen in the drawing, the tightening belt (37) may have a length such that the freely movable portion of the other end of the tightening belt (37) can wrap around the sleeve (30) once and extend beyond the end fixed to the frame (39).

A friction layer (37') may be formed on both surfaces of the above-described fastening belt (37). The friction layer (37') formed on the surface of the above-described fastening belt (37) can provide frictional force between it and the elastic member (47) to be described below, thereby ensuring that the fastening belt (37) is properly fixed by the elastic member (47). The formation of the friction layer (37') on the above-described fastening belt (37) is well illustrated in FIG. 4. The friction layer (37') may be formed of any material that can provide frictional force. Alternatively, the friction layer (37') may be formed by attaching a fabric to it. The fabric may be any material that can provide a predetermined frictional force.

A frame (39) is installed in the space (35) between the inner sleeve (31) and the outer sleeve (33). In the illustrated embodiment, the frame (39) has a cross-section in the shape of the letter 'ㄷ'. However, the shape of the frame (39) may vary.

For reference, the drawing schematically depicts the frame (39) and its associated components. Therefore, the dimensions or relative dimensions of the frame (39) itself and its associated components cannot be determined from the drawing. In other words, the primarily functional portions of the components constituting the present invention can be identified from the contents depicted in the drawing.

The frame (39) of the illustrated embodiment is provided with a first plate (39') and a second plate (39") arranged side by side. The first plate (39') and the second plate (39") are approximately rectangular and are connected at one end thereof by a connecting plate (40). For example, the length of the first plate (39') and the second plate (39") may be approximately 2 to 3 cm, and the width may be approximately 1.5 cm. The width of the connecting plate (40) may be the same as that of the first plate (39') or the second plate (39"). The length of the connecting plate (40) may be the same as the distance between the first plate (39') and the second plate (39"). In the illustrated embodiment, the length of the connecting plate (40) is shown to be relatively long.

The space surrounded by the first plate (39'), the second plate (39") and the connecting plate (40) is called a frame space (41). Inside the frame space (41), there is an elastic member (47) to be described below, and a tightening belt (37) passes through it.

A pin hole (410) may be formed in the first plate (39'). A fixed pin (45), which will be described below, may be press-fitted into the pin hole (410) and joined. There may be multiple pin holes (410). In the illustrated embodiment, two pin holes (410) are formed. However, two or more pin holes (410) may be formed depending on design conditions.

The above connecting plate (40) may be provided with an elastic member fixing portion (412). One end of an elastic member (47) to be described below may be fixed to the elastic member fixing portion (412). The connecting plate (40) may also be formed with a tightening band hole (414). If the elastic member fixing portion (412) is formed at a position adjacent to the first plate (39'), the tightening band hole (414) may be formed at a position adjacent to the second plate (39"). Of course, the elastic member fixing portion (412) and the tightening band hole (414) may be formed at positions opposite to those illustrated.

A button hole (416) may be formed in the second plate (39"). The button hole (416) is a portion through which a connecting leg (493) of a button (49) to be described below passes. Two button holes (416) are formed at a predetermined interval. The interval between the button holes (416) is smaller than the width of the tightening belt (39).

A fixed piece (43) may be fixed to the outer surface of the sleeve outer shell (33). The fixed piece (43) is a part that fixes the frame (39), etc. In the illustrated embodiment, the fixed piece (43) may be fixed to the outer surface of the sleeve outer shell (33) of the sleeve (30). However, the fixed piece (43) may also be fixed to the inner surface of the sleeve outer shell (33). In addition, the fixed piece (43) is not necessarily used, and the frame (39) may be fixed to the sleeve outer shell (33).

The above fixed piece (43) may have a fixed pin (45). The fixed pin (45) may serve to fix the fixed piece (43) to the frame (39). The fixed pin (45) may be fixed to a pin hole (410) of the frame (39), i.e., a pin hole (410) of the first plate (39').

An elastic member (47) is provided within the frame space (41). The elastic member (47) is configured to fix one side of the tightening band (37) to the frame (39). The elastic member (47) is configured as a plate spring. The elastic member (47) configured as a plate spring has one end, that is, a fixed end (471), fixed to the elastic member fixing portion (412), and the other end, that is, a pressing end (473), as a free end, so that it can be in close contact with the inner surface of the second plate (39"). The tightening band (37) may be provided between the second plate (39") and the free end of the elastic member (47).

The elastic member (47) may have a height difference between the fixed end (471) and the pressing end (473). The shape of the elastic member (47) may be varied, different from that shown in the drawing. That is, any shape is acceptable as long as the pressing end (473) can press the tightening band (37) against the second plate (39"). For example, a portion of the pressing end (473) may protrude toward the second plate (39") in an arch shape.

There may be a button (49) on one outer side of the frame (39). The button (49) operates the elastic member (47). When the button (49) is pressed, the pressing end (473) of the elastic member (47) is separated from the tightening band (37).

The above button (49) is composed of a button plate (491) and a connecting leg (493). The button plate (491) can be installed with a slight gap between it and the outer surface of the second plate (39"). The connecting leg (493) extended from the button plate (491) can protrude into the frame space (41) through the button hole (416) of the second plate (39") and be connected to or in contact with the elastic member (47).

In the illustrated embodiment, the connecting leg (493) is connected to the pressing member (473). However, the connecting leg (493) may be connected to either side of the elastic member (47) as long as the pressing member (473) can perform a motion to separate from the tightening band (37).

Meanwhile, Fig. 5 schematically illustrates the configuration of another embodiment of the present invention. The description of this embodiment will be described by assigning the same drawing reference numerals to only those parts that differ from the embodiment described above.

In this embodiment, the positions where the button (49) and the elastic member (47) can come into contact or be connected are different from the above embodiment. In addition, there is a button elastic member (50) so that the button (49) can maintain a predetermined gap with the second plate (39") until a certain amount of force is applied. This is to prevent the button (49) from being operated by the wearer's daily wrist movements.

In this embodiment, the connecting leg (493) of the button (49) can contact the elastic member (47) at a position closer to the fixed end (471) than the pressing end (473) of the elastic member (47). This is to prevent the pressing force on the tightening belt (37) from decreasing even if only a slight force is applied to the button (49).

And, the button elastic member (50) that exerts elasticity between the button (49) and the frame (39) is such that the force applied to the button (49) can elastically deform the button elastic member (50) so that the button (49) moves.

In the embodiment illustrated in Fig. 5, the button (49) is provided at a position where it can come into contact with the elastic member (47) and the button elastic member (50) are provided at the same time, but this is not necessarily the case. Either of these two configurations may be applied.

In addition, the button elastic member (50) may be located at a location other than between the second plate (39") and the button plate (491). For example, it may be configured so that the button (49) exerts elastic force in a direction away from the second plate (39") while being located within the frame space (41).

Hereinafter, the use of the sleeve tightening device according to the present invention having the configuration described above will be described in detail.

The use of the sleeve tightening device of the present invention will be described with reference to FIGS. 6 and 7. First, in order to tighten the sleeve (30), the tightening band (37) between the sleeve inner lining (31) and the sleeve outer lining (33) is rolled.

To this end, force is applied in the direction indicated by arrow A in Fig. 6 so that the tightening band (37) is rolled between the sleeve lining (31) and the sleeve outer covering (33). When force is applied to the sleeve (30) in the direction of arrow A in Fig. 6, the tightening band (37) moves in the direction of the dotted arrow and tightens the sleeve (30). At this time, if the force in the direction of arrow A on the right side of the drawing is slightly greater than the force in the direction of arrow A on the left side, the tightening band (37) can be rolled into a circle more effectively.

At this time, the tightening belt (37) moves while overcoming the elastic force of the elastic member (47). That is, the tightening belt (37) moves by the force applied by the wearer to the tightening belt (37) and overcomes the elastic force of the elastic member (47).

When the force acting in the direction of arrow A is removed, the elastic member (47) applies the elastic force to the tightening band (37) as before. In particular, the direction in which the tightening band (37) is about to be released is opposite to the direction in which the free end of the elastic member (47) is extended, so the tightening band (37) does not release against the elastic member (47).

In this way, the wearer can tighten the sleeve (30) by applying force to the sleeve (30) of one wrist with the other hand, thereby causing the tightening band (37) to roll. The tightened state of the sleeve (30) is illustrated in Fig. 7, and it can be seen that the area where the tightening bands (37) themselves overlap each other has increased relatively compared to Fig. 6.

Next, the tightening of the sleeve (30) is loosened by loosening the tightening belt (37) described above.

To do this, simply operate the button (49). By inserting your finger between the sleeve (30) and your wrist and pressing the button (49), the connecting leg (493) of the button (49) separates the elastic member (47) from the fastening band (37). In this way, the fastening band (37) tends to loosen, and the fastening band (37) moves in the direction indicated by the dotted arrow in Fig. 7. Accordingly, the overlapping portion of the fastening band (37) decreases, and the sleeve (30) is released.

For reference, the wearer may not directly press the button (49), but may press the portion of the fixed piece (43) corresponding to the button (49). In this case, when the button (49) is pressed while the sleeve outer cover (33) is placed on the wearer's wrist, the elastic member (47) may be released from the fastening belt (37).

The degree to which the above-mentioned tightening belt (37) is loosened can be adjusted by removing the force applied to the button (49). When the wearer checks the degree to which the sleeve (30) is loosened and removes the force applied to the button (49), the tightening belt (37) stops loosening and the sleeve (30) is loosened to the desired degree.

Even though all components constituting the embodiments according to the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined and operated one or more times. In addition, terms such as "include," "comprise," or "have" described above, unless specifically stated to the contrary, mean that the corresponding component may be inherent, and therefore should be interpreted as including other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as being consistent with the contextual meaning of the related technology, and shall not be interpreted in an ideal or overly formal sense, unless explicitly defined in the present invention.

The above description is merely an illustrative illustration of the technical idea of the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate, rather than limit, the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
