Description

Multipurpose attachment device {MULTI-PURPOSE ATTACHMENT DEVICE}

The present invention relates to a multipurpose attachment device for a backpack. More specifically, the present invention relates to a sliding device attached to a backpack, which can be connected to several different attachment pieces to hold various tools.

Hikers and cyclists often need to attach various tools outside their backpacks. For example, items such as flashlights, keys, hydration tubes, etc. are more convenient to carry in a place where the hand can easily reach on the shoulder strap rather than inside the backpack. This allows the user to hold the tool without having to remove the backpack. This is especially important for water supply tubes that must be reachable while riding on a bicycle.

Depending on the structure or shape, there are several devices that are secured to the shoulder straps of the backpack to hold the water supply tube or other tool. However, the user may need a different device for each day of the planned activity. Attaching several different devices to the shoulder straps is inconvenient and unwieldy. Therefore, it would be desirable to have an attachment for a backpack shoulder strap that can accommodate a variety of different tools.

It is therefore an object of the present invention to provide a strap attachment device that can be used to hold a variety of different tools.

Still another object of the present invention is to provide a strap attachment device that can also be attached to a chest strap.

Another object of the present invention is to provide an attachment device which is simple to manufacture and inexpensive.

These and other objects are achieved by a strap attachment device comprising a base, means for attaching the shoulder strap of the backpack to the base, and a removable catch mechanism for securing the tool holder. The present invention also includes one or more tool holders adapted to be detachably secured to the body via a removable catch mechanism.

Means for attaching the gas to the backpack include two arms disposed along the opposite edge of the gas. Each arm has a transverse through slit for fitting gas onto the string. Preferably, the slits are biased from the center of each arm to make it easier to separate and attach the gas to the string.

There may also be two additional arms disposed at the other opposite edge of the gas, so all four gas edges have arms. All arms have transverse through slits, so the gas can be secured to two strings that are at right angles. This feature is particularly important when the backpack has both a shoulder strap and a chest strap. In this way, the attachment device can be secured to the chest strap and the shoulder strap and cannot slide around at all.

The detachable catch mechanism includes a sidewall extending upward from the upper surface of the body, the sidewall having an overhanging lip. The gas is integrally formed with a flexible arm, which has a free end extending above the plane of the gas. The flexible arm may have a free end extending towards or opposite the sidewall, ie the origin of the flexible arm may be disposed directly opposite or adjacent to the sidewall. The free end of the flexible arm has a contact surface against a side of the tool holder inserted between the free end and the side wall. The tool holder includes a plate, a holder portion attached to the upper surface of the plate, and an attachment portion extending from the lower surface of the plate. The attachment portion includes a flange extending outwardly. The tool holder is connected to the gas by sliding the flange over the flexible arm and inserting it under the protruding ribs. The flexible arm exerts an upward pressure on the flange, forcing the flange against the lip to hold the flange in place. The contact surface of the flexible arm prevents the tool holder from sliding backwards and prevents the tool holder from accidentally falling out. The tool holder is released by pressing the flexible arm such that the holder releases the contact surface. In order to prevent the tool holder from sliding from the lip, the side wall and the protruding lip are preferably U-shaped.

The contact surface may be formed from a protrusion located on the flexible arm. The protrusion is in contact with the flange to prevent backward movement of the tool holder.

The tool holder can take many forms and have infinitely many variations, depending on the function of use. One variation is a water supply tube holder comprising a plate and an S-shaped flexible arm coupled to one end of the plate. The water supply tube is held in place by sliding the tube between the plate and the arm. The sigmoidal curve of the arm prevents the tube from falling out.

Another variant is a flashlight holder consisting of a plate and a flexible C-shaped fixing element attached to the plate center. The flashlight can be snapped into the C-shaped holder element and held there by friction of the holder element. The D-shaped ring may be rotatably attached to the plate.

Preferably, the aircraft is provided with several tool holders to allow the user to select a tool holder for daily use.

In a variant, the detachable catch mechanism includes a circular wall having an inwardly projecting lip. The tool holder includes a plate having an upper surface and a lower surface, a fixing portion attached to the upper surface of the plate, and two flexible bayonet catches extending from the lower surface of the plate. The tool holder is attached to the body by inserting the catch into the circular wall such that the bayonet catch catches the protruding ribs to secure the tool holder to the body.

Other objects and features of the present invention will become apparent upon consideration of the following detailed description taken in conjunction with the drawings. However, it should be understood that the drawings are only examples and do not limit the scope of the invention.

In the drawings, like reference numerals refer to like elements throughout the several views.

Referring now to the drawings, in particular with reference to FIG. 1, there is shown a body 10 according to the invention in which various tool holders can be coupled. The body 10 is integrally molded as an integral structure with four bars 11, 12, 13, 14 for attaching the gas to one or more straps. As shown in FIG. 2, each bar 11, 12, 13, 14 has a transverse slit 15 to fit the strap 16, 17 or other article of the backpack 18 into the body.

The mechanism for attaching the tool to the base 10 includes a semicircular wall 19 having a protruding lip 20 and a flexible arm 21 having a free end extending from the semicircular wall 19. The free end of the flexible arm 21 protrudes slightly above the upper surface of the base 10 to exert upward pressure on the tool holder disposed in the base 10, as described below. The arm 21 has a transverse bar 22 extending across its free end and a protrusion 23 at the free end of the arm 21. Once the tool holder is inserted between the free end of the arm 21 and the semicircular wall 19, the protrusion 23 forms a contact surface that prevents the back movement of the tool holder. Once the tool holder is inserted below the protruding lip 20, the transverse rod 21 and the protrusion 23 hold the tool holder in place to engage the tool holder in the base 10. To detach the tool holder, the arm 21 must be depressed enough to allow the tool holder to release the protrusion 23. As will be described later, the protrusion 23 is also provided at a position convenient for the user to press the arm 21 to release the tool holder.

One example of a suitable tool holder is the water supply tube clip 25 shown in FIG. 3. The tube clip 25 comprises a plate 26, on which a resilient S-shaped arm 27 is mounted. A water supply tube (not shown) slides in between the plate 26 and the arm 27. The tube is preferably wider than the lower end of the arm 27 once it is mounted between the plate 26 and the arm 27. The clip 25 is secured to the base 10 by a hexagonal flange 28 extending outward below the plate 26.

4 and 5 illustrate a process of fastening the clip 25 to the base 10. The flange 28 slides under the lip 20 and is pushed upwards by the arm 21 of the base 10 so that the clip 25 is fastened to the base 10.

Another suitable tool holder is a flashlight holder 30 or a D-shaped ring 31, as shown in FIGS. 6 to 8. The flashlight holder 30 is held in place by the flange 32 like the flange 28 on the clip 25. The flashlight holder 30 has a C-shaped fixing element 38 which functionally supports the flashlight therein. The D-shaped ring 31 fastened to the base 10 is fastened in a similar manner by the flange 32. The D-shaped ring 31 is composed of a ring portion 36 which is rotatably coupled to the flange 32 by a hinge 35 mounted in the side bracket 34.

Various tool holders may be separated from the body 10 in the manner shown in FIGS. 9-10. The user only needs to press down on the flexible arm 21 so that there is enough clearance above the protrusion 23 to allow the tool holder to slide out of the body 10. In this way, the tool holders are easily interchanged to accommodate the user's desire to change.

The base 100 is also provided with a circular vertical wall 180 having a protruding lip 190 inward to fasten the tool holder into the base 100.

A suitable tool holder is shown in FIG. 12 in the form of a water supply tube clip 200. Tube clip 200 has two bayonet catches 220 mounted thereunder. Bayonet catch 220 is engaged into protruding rib 190 when clip 200 is pushed into body 100. Any type of tool holder with bayonet catch can be used in the base 100. In addition, any other fastening mechanism used to hook the body 100 may be used.

Another embodiment is shown in FIGS. 14, 15A, and 15B. For this embodiment, the gas 10 'includes a semicircular wall 19' with a protruding lip 20 '. A flexible arm 21 'having a free end is mounted opposite the wall 19' and extends towards the wall 19 '. As described below, the free end of the flexible arm 21 'projects slightly above the top surface of the base 10' and exerts an upward pressure on the tool holder 25 mounted in the base 10 '. The arm 21 'has a transverse bar 22' extending across its free end and a protrusion 23 'at the free end of the arm 21'. Once the tool holder is inserted below the protruding lip 20 ', the protrusion 23' holds the tool holder 25 in place by forming a contact surface in the tool holder, so that the tool holder 25 in the base 10. Fasten. The tool holder 25 slides over the arm 21 'and the protrusion 23' and is installed below the protruding lip 20 '. The protruding lip 20 'prevents movement in either direction, while the protrusion 23' prevents movement in the other direction, thereby locking the tool holder 25 in place.

To remove the tool holder, the user only has to press down on the projection 23, whereby the tool holder is sufficient to slide out of the protruding lip 20 'over the projection 23' and the arm 21 '. A gap is created.

As such, although only a few embodiments of the invention have been illustrated and described, it will be apparent that many changes and modifications can be made therein without departing from the spirit and scope of the invention.
