Description

DETAILED DESCRIPTION OF THE INVENTION Background of the Invention

The invention described herein relates to improvements in wheeled bags and related equipment. Traditionally, wheeled luggage has one or more wheels that are integrally attached to the luggage frame. The bag is provided with a telescoping or folding handle so that it can be pushed and pulled on the ground. The user
By using this handle, it is not necessary to carry the entire bag and carry the entire bag to carry the bag.

[0002] To provide more stability and support to the bag, some have deployed telescoping panels further comprising one or two wheels. The telescoping panel is automatically enabled when the handle is pulled up. Additional wheels to improve the maneuverability of the bag may be casters. Examples of such articles are described in U.S. Patent Nos. 5,519,919 and 5,568,848.

[0003] One of the disadvantages of the devices described in the two patents mentioned above is that the telescopic panel with one or more additional wheels is automatically enabled when the handle is raised. It is. Therefore, the telescoping panel is ready for use even if one or more additional wheels do not require stability and support. Until now, there was no way to keep the telescoping panel unused when the bag handle was extended.

[0004] Therefore, there is a need for an improved wheeled luggage to overcome the disadvantages of the prior art described above, as well as a fastening system for the handle, casters arranged on the telescoping panel, and Improvements are also required for pushbutton mechanisms and the like.

[0005] SUMMARY bag of the present invention the invention addresses the above and other requirements. The bag includes a housing and first rolling means protruding from the housing. In addition, a wheel-equipped panel mechanism having a second rolling means and having a rotatably mounted panel is provided. A handle is connected to the wheeled panel mechanism, and the handle is movable between a storage position and an extended position. The bag has means for selecting whether to use the second rolling means when the handle is moved from the storage position to the extension position. Therefore, even when the handle is in the extended position, it is possible to select whether or not to use the second rolling means.

[0006] An improved fastener means for the second rolling means and an improved caster system are also disclosed. Also disclosed is a wheeled panel mechanism that can be used not only for bags, but also for other items such as carts, dolly, and baby buggy. An improved pushbutton device is also disclosed.

[0007] The present invention will become more fully understood from the following detailed description of the invention when read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION One basic concept of the invention disclosed in this specification is more particularly illustrated by FIGS. 1-3, and will be described with reference thereto. A bag (20) is shown. In this embodiment, the bag (20) has an integral frame or gusset (22) made of plastic. Inside the bag (20), an accommodating portion (24) is formed using a cloth cover (not shown). The present invention is shown in the drawings, the outer body is soft (
It will be appreciated that, besides a soft-sided (or gusseted) bag, the outer body may be used in a hard-sided bag. In a broad sense, the bag (20) has handle means (26), and the handle means (26) has a pair of spaced male pipe members (28) (30). The upper portions of the male pipe members (28) (30) are joined by a grip (32). The male pipe members (28) and (30) are fitted into the female pipes (40) and (42). It will be appreciated that the male tubing members (28) (30) and the grip (32) can be moved from the stowed position shown in FIG. 1 to the extended position shown in FIGS.

FIG. 2 shows the bag (20) when the handle means (26) is in the extended position. In this position, the bag (20) can be moved while rolling along the surface by the first rolling means. The first rolling means shown here is a pair of wheels (44) (46) arranged at intervals. The structure and arrangement of these wheels is well known to those skilled in the art.

Referring to FIG. 3, the bag (20) is shown with the handle means (26) extended. A wheeled panel mechanism (50) having second rolling means is provided. The second rotating means is a novel caster (52) (54) which is a feature of the present invention, and is rotatably mounted on the wheeled panel mechanism (50) by a caster support rod (55).

The whole of 170) moves downward until the projection is locked again by the locking device (see FIG. 12).

With reference to FIGS. 16 to 18, a novel caster which is a feature of the present invention will be described. With particular reference to FIG. 16, there is shown a caster (200) connected to a telescoping portion (202). The extendable portion (202) may be, for example, an extendable panel similar to the rotatable panel (56) of the wheeled panel mechanism (50) shown in FIG. Examples of the extendable portion (202) are shown in the partial cross-sectional views of FIGS. The illustrated caster (200) is stored in a space (204) in an article (205) such as a wheel-mounted panel mechanism (50). As will be described in greater detail below, one of the structural advantages of casters (200) is that casters (200) fit well into space (204) when retracted and stored.

[0032] The caster (200) includes wheels (210), a wheel frame (212), and a swivel (214). The swivel (214) has a rod (216) which has a cross pin (217) extending therefrom to guide means (218) formed in the telescoping part (202). Have. The wheel frame (212) connects the swivel (214) to the wheel (210), and is rotatably attached to the swivel (214) by a pair of connectors (220) (222). As shown in FIG. 17, the wheel (210) has an axis (223), and the axis (2
23) is rotatably mounted with both ends pivotally supported by the wheel frame (212). The extendable portion (202) also includes a biasing means. In this embodiment, the biasing means is a spring (224), one end of which is fixed to the wall (226) of the extendable part (202) and the other end of which is a rod (216). It is pressed against the upper surface. The spring (224) biases the caster to the storage position. Here, since the cross pin (217) is engaged with the V-shaped guide means (218), a gap (228) is formed between the swivel (214) and the bottom surface (202a) of the extendable portion (202). Is formed.

Referring to FIG. 17, when the extendable portion (202) moves from the storage position shown in FIG. 16 and the wheel (210) comes into contact with the surface (230), the entire caster (200) is moved in the direction indicated by the arrow A. As shown by, it is pushed upward against the urging force of the spring (224). Then, the cross pin (217) moves away from the V-shaped guide means (218). Where swivel
(214) is free to rotate 360 ° about a vertical axis (240). this is,
When the casters (200) are supported on the surface (230), the casters (200) are advantageous in that they can assist the movement of articles placed in any direction, such as a bag. It will be appreciated that the cross pin (217) prevents the caster (200) from being disengaged from the extendable portion (202).

As shown in FIG. 16, when the extendable portion (202) is retracted and stored, the caster (200) is arranged at a predetermined position, and efficient and space-saving storage is performed. It will be appreciated that this is desirable. Referring to FIG. 18, when the caster (200) is lifted away from the surface (230), the spring (224) urges the caster (200) downward, as indicated by arrow B, causing the rod (216) to move downward. ) And cross pin (2
17) moves downward. With this bias, the cross pin (217) abuts on the V-shaped guide means (218), which acts on the cross pin (217), and the entire caster (200) moves on the vertical axis (240). , Rotate to a position defined by the configuration and arrangement of the guide means (218). This position is set based on the structure of the article to which the caster is attached and / or the extendable part. When the wheel (210) is lifted off the ground, if the caster is already in a predetermined position, the caster (200) does not rotate, of course. Thus, whenever the wheel (210) is lifted off the ground, the caster (200) is in a predetermined position that represents a particular desired orientation to efficiently accommodate the caster (200).

Although the illustrated casters (200) are on the telescoping portion (202), the invention is not so limited, and the disclosed caster structure is useful for the wheels while they are on the surface. It is desirable to use casters that can move freely, but when the wheel is lifted away from the surface, if it is desirable to be in a predetermined position that indicates a specific desired orientation, if there is no expandable part, It will be appreciated that any article can be used regardless.

Referring again to FIG. 16, as indicated by arrow C, the wheel frame of the caster (200) is more efficiently housed in the space (204).
It will be appreciated that (212) is adapted to pivot about a pivot position P.

Having described certain embodiments of the invention, those skilled in the art will appreciate that
It will be understood that various changes and modifications may be made in those details by reference to the entire disclosure. Therefore, the specific configurations disclosed are merely exemplary and do not limit the scope of the invention. The scope of the invention is to be accorded the widest scope of the appended claims and to their equivalents.
