table tennis bag

technical field

The present disclosure relates to a bag for table tennis.

Background technique

Since lightweight table tennis balls typically fly or bounce off after one or more successful hits by one or more players, those who play table tennis need to have a large number of table tennis balls nearby. In order to avoid unnecessary interruptions during competition or training to retrieve the balls, players therefore usually store some table tennis balls in the pockets of their sweatpants. However, the disadvantage of this approach is that the ping pong ball in the person's pocket may interfere with his or her movement during the game. Furthermore, since there is only room for a few balls in the trouser pockets, the interruption of play to retrieve the balls cannot be completely avoided anyway.

There are various types of bags that can be worn by a person to hold items. However, the design of these bags makes them unstable when worn by a person making sudden and powerful movements during a game of table tennis. Furthermore, the rather large opening of known bags does not ensure safe storage of small and lightweight table tennis balls within the bag during table tennis games and training.

US5289960 shows a soft bladder for containing tennis balls. The bag is formed from two superimposed semi-elliptical sheets of flexible fabric which are sewn together along their circular borders (ie A-B from Figure 2A of US5289960). Elastic material is applied along the unstitched hems of the overlapping sheets, and the hems are then folded over each other in a criss-cross fashion, forming an elastic opening that allows access to the interior of the bag. The hem thus also folds over the ends of the strap of the bag, and eventually the ends of the strap and the opposite ends of the cross-lap hem are secured to each other by stitching. (See pin 6 in Figure 1 of US5289960).

However, the tennis pouch in US5289960 suffers from several disadvantages. Firstly, the step of achieving the opening in the bag by criss-cross folding of the hem followed by sewing is complicated and results in a narrow opening for the hand of the wearer of the bag. Accordingly, it may be uncomfortable or even difficult for the wearer to force his hand through the criss-cross opening to gain access to the interior of the bag. The soft nature of the pouch in US5289960 may further cause the pouch to move around the back of the wearer of the pouch and thus experience instability during a game of table tennis.

It is therefore an object of the present disclosure to provide an improved bag for containing table tennis balls worn by a person during table tennis games and training which solves at least one of the problems of the prior art. In particular, it is an object of the present disclosure to provide a bag for containing table tennis balls and having an opening which both securely holds the table tennis balls within the bag and allows the wearer to easily access the table tennis balls from the bag. Furthermore, it is an object of the present disclosure to provide a bag for accommodating table tennis balls which can be stably supported on the back of a person wearing the bag. Yet another object of the present disclosure is to provide a bag for containing table tennis balls that is easy to manufacture.

Contents of the invention

According to the present disclosure, at least one of the above objects is achieved by a bag configured to be worn on the back of a person for containing table tennis balls, the bag comprising:

- a top and a closed bottom, wherein the top has an opening for the ping pong ball, the bottom is oriented along the longitudinal direction (y), wherein the opening is elongate and comprises a spring arranged to bias the opening towards the closed position Material;

- a front side and a rear side, the front side and the rear side extend along the first transverse direction (x) between the top and the bottom, and the front side and the rear side extend along the longitudinal direction (y) and the first transverse direction (x) spaced apart from each other in the second transverse direction (z) of intersection;

- Attachment means for attaching the bag to the body of a person, wherein the bag is configured such that when the bag is worn on the back of the person, the bag is in a longitudinal direction along the back of the person wearing the bag (y) extends upward so that a person can reach the opening and such that the back side faces the back of the person wearing the bag and the front side faces away from the back of the person, wherein the back side rests against the back of the person wearing the bag such that the bag is in supported against the back of a person in a first transverse direction (x), characterized in that the top comprises a cover extending in a second transverse direction (z) from the rear side to the front side of the bag and the cover comprises an opening, and wherein the opening is formed by an elongated slit in the cover and the opening comprises mutually facing first and second elongated edges extending parallel to each other, and wherein the elastic material is adjacent the first elongated edge and the second elongated edge are arranged such that the first and second elongated edges are offset toward each other.

A major advantage of a bag for containing table tennis balls according to the present disclosure is that the bag comprises a flat cover extending across the top of the bag in a second transverse direction (z) and an opening defined by an elongated slit in the cover The opening is formed and has a first elongated edge and a second elongated edge facing each other, the first elongated edge and the second elongated edge facing each other are biased toward each other by a resilient material disposed adjacent the edge of the slit place.

This arrangement provides easy access to the opening of the bag by the wearer of the bag because the top cover (with the opening) extends generally orthogonally from the wearer's back. The design of the opening encourages the opening to always be closed, preventing the ping pong ball from falling out of the bag during the game. However, the person wearing the bag can easily reach his hand into the opening in the top cover to access the ping pong balls from the bag without being obstructed by the edge of the opening or the surrounding cover material.

Another advantage is that the rear side of the bag is elongated and extends in the lateral direction of the bag. Thus, when the back side of the bag is in supporting abutment with the back of the person wearing the bag, good lateral support of the bag on the back of the person is provided. This in turn prevents the bag from swinging or spinning, even in the event of sudden and powerful movements by the person wearing the bag during a game of table tennis.

Preferably, the rear side is flat, ie in the form of a flat plate. This design can be realized at low cost and is suitable for a large number of table tennis players. According to another preferred alternative, the rear side is concave, which in turn provides a tight fit and a very good abutment with the back of the person wearing the bag.

Preferably, the front and/or rear sides of the bag are rigid. The bag is thus self-supporting, with the result that the shape of the bag can be maintained when the bag is worn on a person's back. This in turn causes the top cover with the opening to always extend normal to the wearer's back and thus be easily accessible during table tennis games and training. The rigidity also increases the stability of the bag against the back of the person wearing the bag.

Detailed ways

A bag for table tennis according to the present disclosure will be described more fully hereinafter. Bags for table tennis according to the present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout the specification.

Figure 1 shows a bag 1 for containing table tennis balls (hereinafter referred to as "bag") according to a first alternative of the present disclosure. For reference purposes, it should be noted that the table tennis ball is spherical, has a diameter of about 44mm and weighs about 2.7g, and is made of plastic material.

The bag 1 comprises a top 10 and a closed bottom 11 oriented along the longitudinal direction y, ie along the vertical axis y. The top 10 and bottom 11 are spaced apart from each other by a distance defining the height h of the bag 1 (see Fig. 2). The top 10 also includes a cover 10.1 with an opening 16 for receiving a table tennis ball, as will be described further below. The bag 1 also has a front side 12 and a rear side 13 extending between the top 10 and the closed bottom 11 of the bag. The front side 12 and the rear side 13 are connected to each other, and the front side 12 and the rear side 13 are connected to the closed bottom 11 and the top cover 10.1, so that the top cover 10.1, the front side 12, the rear side 13 and the closed bottom 11 are formed for receiving and a closed container to hold the ping pong balls.

A handle 20 is attached to the top 10 . Obviously, the front side 12, rear side 13 and optional closed bottom 11 and top 10 of the bag are sized so that the bag can receive and hold a desired number of table tennis balls, for example 5 or 10 or 20 table tennis balls .

The front side 12 and the rear side 13 extend along a first transverse direction x defined by a transverse axis x orthogonal to the longitudinal axis y. The maximum extension of the front side 12 and the rear side 13 in the first transverse direction x defines the width w of the bag 1 (see FIG. 2 ). The front side 12 and the rear side 13 are further spaced apart from each other in a second transverse direction z defined by a second transverse axis z orthogonal to both the longitudinal axis y and the first transverse axis x (see Fig. 1). The distance separated by the front side 12 and the rear side 13 in the second transverse direction z defines the depth of the bag. The cover 10.1 extends from the rear side 13 to the front side 12 in a second transverse direction z.

It should be understood that "longitudinal and transverse directions" refer to any two directions of the respective longitudinal axis y and transverse axes x, z.

The front side 12 and/or the rear side 13 and possibly the bottom 11 may be rigid such that the bag is self-supporting. For example, the front side 12, the rear side 13 and possibly the bottom 11 may be made of padded nylon, or include reinforcing elements such as plastic ribs or sheets. By "self-supporting" is meant the ability of the bag to retain its shape when worn on a person's back or when the bag is placed on a surface.

According to the present disclosure (see Figures 1 and 1a), the cover 10.1 of the top 10 of the bag 1 comprises an opening 16 for a table tennis ball. The opening 16 is arranged and dimensioned such that a person wearing the bag can reach into the opening 16 . It should be appreciated that the opening 16 is permanently arranged such that a person wearing the bag can reach into the opening 16 . Thus, the opening is free of locking means, such as zippers, that need to be manipulated to open the opening 16 .

The opening 16 is elongate and comprises mutually facing first 16.1 and second 16.2 longitudinal elongate edges extending parallel to each other. As shown in Figure 1a, the elongated parallel edges 16.1, 16.2 are straight elongated edges. The cover 10.1 also comprises a resilient material 17 which is arranged adjacent to the elongated edges 16.1, 16.2 and which biases, ie urges, the elongated edges 16.1, 16.2 towards each other. That is, towards the closed position indicated by the dashed line in Figure 1a. In the closed position, the mutually facing elongated edges 16.1, 16.2 are in contact with each other. Especially in the closed position, the mutually facing elongated edges 16.1, 16.2 are in non-locking contact with each other. Alternatively, the distance between the mutually facing elongated edges 16.1, 16.2 is smaller than the diameter of the table tennis ball. Preferably, the elastic material 17 is an elastic material such as a rubber material. More preferably, the elastic material is a first elastic strip 17 and a second elastic strip 17 adjacent to the respective first longitudinal edge 16.1 and second longitudinal edge 16.1 of the opening 16 The edge 16.2 is attached (for example by sewing) to the cover 10.1. In effect, the elastic material 17 stretches the cover 10.1 close to the first longitudinal edge 16.1 and the second longitudinal edge 16.2, so that the edges are biased towards each other, ie pressed.

The bag 1 also comprises attachment means 18.1, 18.2 for releasably attaching the bag 1 to a person's body. In the embodiment shown in FIG. 1 , the attachment means are a first strap 18.1 and a second strap 18.2, each attached by one end to the top 10 of the bag 1 and arranged to be worn around Wrap 1 around the body of the person such as the waist. Preferably, the attachment means 18.1, 18.2 are arranged such that they extend from the rear side 13 of the bag (ie from the longitudinal edge of the rear side) to ensure that the rear side 13 rests firmly against the back of the person wearing the bag. The free ends of the first strap 18.1 and the free ends of the second strap 18.2 may be provided by attachment means 19, such as Velcro ^™ , so that the free ends of the straps can be attached to each other in a releasable manner. The first strap 18.1 and the second strap 18.2 may also comprise respective wings 18.3 (see FIG. 2 ) extending from the rear side 13 of the bag 1 along a part of the respective strap 18.1 , 18.2 and towards the closed end of the bag 1 . Bottom 11 extends. The wings 18.3 increase the stability of the bag against the back of the person wearing it.

The bag 1 is configured to be worn on the back of a person 2 . This is an important feature of the present disclosure because the bag is intended to supply balls to people practicing table tennis. In this case, the person wearing the bag needs to wear the bag on the back, otherwise the bag will hit the ping pong table. Figure 4 shows a person 2 wearing a bag 1 according to the present disclosure on the back. According to the present disclosure, and as shown in FIG. 4 , the bag 1 is configured such that when the bag 1 is worn on the back of a person 2 , the front side 12 of the bag faces away from the back of the person 2 wearing the bag and the rear side 13 faces towards the back of the person wearing the bag 1 . Person 2's back. This can eg be achieved by arranging the attachment means 18.1, 18.2 such that the attachment means extend from the rear side 13 of the bag (see Figures 1 and 2). It is also worth noting that the top cover 10.1 of the bag extends orthogonally to the person 2's back.

Furthermore, since the bag is intended to supply ping pong balls to the person wearing the bag, it is important that the bag 1 is constructed such that the person wearing the bag can reach the opening 16 in the top of the bag 1 and pass the hand through the opening 16 into the bag. internal. In this regard, the configuration of the bag 1 can be achieved by dimensioning the extension of the bag along the back of the person wearing the bag in the longitudinal direction y, ie the height h of the bag. For example, the height h of the bag is sized by referring to the height of a standard person. In this regard, the bag 1 can also be configured by means of the position of the attachment means 18.1, 18.2. The attachment means 18.1, 18.2 may thus extend from the top 10 of the bag. When the attachment means 18.1, 18.2 are subsequently wrapped around the person's body, eg around the abdomen or waist, the top 10 of the bag will automatically be in position to allow the hand of the wearer of the bag to enter the opening 16.

Therefore, in order to allow full access to the opening at the top of the bag, the bag is preferably configured to be worn on the lower half of the back of the person 2 wearing the bag. That is, in the region extending from the buttocks to the middle of the person's back. The lower half of the person's back may also include at least a portion of the person's buttocks. Typically, the bag is sized such that its height h is smaller than the lower half of the back of the person wearing the bag. Furthermore, the width of the bag is sized such that it is equal to or smaller than the width of the back of a person wearing the bag. This prevents the bag from interfering with the movement of the wearer of the bag. Exemplary dimensions of a bag according to the present disclosure are height: 20cm-25cm, width: 20cm-30cm, depth: 15cm-20cm.

The bag is also configured such that the rear side 13 rests against the back of a person wearing the bag such that the bag 1 is supported against the back of the person in the first transverse direction x. According to the present disclosure, this feature is achieved in that the rear side 13 extends in the first transverse direction x. FIG. 2 shows the rear side 13 of the bag 1 , which in the embodiment shown in FIG. 2 thus forms an abutment surface extending over the width x of the bag 1 . The degree of abutment between the back side 13 of the bag and the person's back determines the degree of lateral support that can be achieved and may be affected by the design of the back side 13 and/or the front side 12 of the bag. In particular, the degree of adjacency may be affected by the cross-sectional design of the package. For example, in the embodiment of FIG. 1 , the bag 1 is semicircular in cross-section (ie straight rear side and curved front side 12 ), so that the rear side 13 extends across the entire maximum width of the bag 1 . This is advantageous because the large adjoining area between the rear side of the bag and the back of the wearer of the bag increases the lateral support of the bag on the back of the person wearing the bag. In Fig. 3c, the cross-section of the bag 1 is faceted, which results in the rear side 13 extending over less than the maximum width of the bag and thus providing less lateral support. In order to ensure a sufficient degree of abutment between the rear side 13 and the back of the person wearing the bag, it is preferred that the rear side 13 extends over at least half of the maximum width of the bag 1 . The degree of abutment between the rear side and the back of the person wearing the bag may also be affected by the size of the bag, ie height, width and depth.

In the longitudinal direction y, the rear side 13 forms an abutment surface extending from the top of the bag 1 to the closed bottom.

The degree of abutment between the rear side and the back of the person wearing the bag can also be influenced by the design of the rear side 13 . FIG. 2 shows an embodiment in which the rear side 13 is flat, ie extends parallel to the transverse axis x. Alternatively, as shown in Figure 3b, the rear side 13 may be concave such that the rear side 13 forms a recess 14 facing the back of the person wearing the bag. However, other designs of the rear side 13 are also possible, for example the rear side can be flat and concave. That is, one section of the rear side may be flat, while the other section may be concave.

It should be understood that the rear side 13 should not be convex in the direction of the back of the person wearing the bag, as this would lead to poor lateral support of the rear surface on the back of the person wearing the bag. Therefore, the rear side 13 should have no protrusions in the direction of the back of the person wearing the bag.

Bag 1 is preferably made of a lightweight fabric such as nylon. The front and back sides may thus be formed from one continuous piece of fabric, or from two or more separate pieces that have been joined together by sewing, gluing or welding. As described, padding or reinforcing material may be integrated in the front and rear sides to provide rigidity. The cover 10.1 may be made of a flexible material such as textile or webbing, and the opening 16 may be formed by an elongated slit in the cover 10.1. Typically, the opening may thus be formed by attaching two parallel strips 16.1, 16.2 of elastic material to the cover 10.1 and cutting a slit through the cover 10.1 between the parallel strips.

While specific embodiments have been disclosed in detail, this has been done for purposes of illustration only and is not intended to be limiting. It is particularly intended that various alternatives, changes and modifications may be made within the scope of the appended claims.

For example, bag 1 may have a different design. Figure 3a shows a cross-sectional view of the bag 1, wherein the rear side 13 is flat, ie has a straight cross-section, and the front side 12 is cylindrical, ie has a semi-circular cross-section. Figure 3b shows the aforementioned alternative where the rear side 13 is concave and the front side is cylindrical, ie has a semicircular cross-section. Figure 3c shows an alternative where the rear side 13 is flat, ie has a straight cross-section, and the front side 12 is faceted. Figure 3d shows an alternative where the rear side 13 is flat, ie has a straight cross-section, and the front side 12 has a rectangular cross-section.

It should also be understood that the features of the various alternatives disclosed above may be combined.
