Description
- This application claims priority of Chinese Application No. 201120239531.8, filed on Jul. 8, 2011.
- 1. Field of the Invention
- The invention relates to a pull belt, more particularly to a pull belt for an inflatable device.
- 2. Description of the Related Art
- Inflatable devices, while not in use, can be deflated to facilitate storage and transport thereof, and are widely used, examples of which include inflatable boats and beds. In order to form a predetermined shape after the inflatable device is inflated, and to prevent undesired deformation of the inflatable device due to overinflation, at least one pull belt may be applied in the inflatable device.
- The pull belt is generally disposed in the inflatable device, and interconnects opposite end sheets of the inflatable device. If a particular shape of the inflatable device is desired, for instance, the raising ends of an inflatable boat, at least one pull belt with curved portions instead of an elongated pull belt has to be applied in the inflatable device.
- Generally, a conventional curved pull belt is directly cut from a cloth material, and has an unchangeable shape. If an alteration of the shape of the inflatable device is desired after the production of the original conventional pull belts of the inflatable device, new pull belts that fit with the modified shape of the inflatable device are required. Therefore, the conventional pull belt has relatively low flexibility in use, and the consumption of the cloth material is relatively high. Moreover, the conventional curved pull belt has insufficient tensile strength at the curved portion thereof. Hence, the curved portions may be stretched to be straight after the inflation of the inflatable device and unable to impart the inflated inflatable device with the predetermined shape.
- Therefore, an object of the present invention is to provide a pull belt that has at least one curved portion and the position of the at least one curved portion may vary as required.
- Another object of the present invention is to provide an inflatable device including at least one of the abovementioned pull belt.
- Accordingly, a pull belt is adapted for use in an inflatable device which includes spaced-apart first and second sheet sections. The pull belt comprises a main belt body having opposite first and second lengthwise end portions that are adapted to be secured respectively to the first and second sheet sections. The main belt body is formed with at least one first pleat at the first lengthwise end portion to bend the main belt body at the at least one first pleat toward the first lengthwise end portion.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
-
FIG. 1 is a perspective view of an inflatable device including a plurality of pull belts according to a preferred embodiment of the invention; -
FIG. 2 is a fragmentary side view of the preferred embodiment; -
FIG. 3 is a sectional view taken along line inFIG. 1 ; and -
FIG. 4 is a fragmentary perspective sectional view illustrating the preferred embodiment of the pull belt that is connected between two sheet portions of the inflatable device. - As shown in
FIGS. 1 and 2 , a preferred embodiment of apull belt 3 according to the present invention is adapted for use in an inflatable device, such as an inflatable boat. The inflatable device has spaced-apart first andsecond sheet sections second sheet sections - The first and
second sheet sections inflation space 6, and thepull belts 3 are disposed in theinflation space 6 in a parallel arrangement and are secured to thesheet sections pull belts 3 has amain belt body 31 having opposite first and secondlengthwise end portions second sheet sections main belt body 31 is formed with a plurality ofpleats 313 at a front portion thereof. Each of thepleats 313 has a crease portion at the firstlengthwise end portion 311 thereof. The crease portion of eachpleat 313 extends transversely from the firstlengthwise end portion 311 toward the secondlengthwise end portion 312. As such, themain belt body 31 is bent at thepleats 313 toward the firstlengthwise end portion 311 and form a bent segment of themain belt body 31. By virtue of the bent segment of thepull belts 3, the inflatable device would have a boat-like shape with a rising front end after inflation. Preferably, each of thepull belts 3 further includes a reinforcingmember 33 secured to themain belt body 31 and extending along the lengthwise direction (L1) to intersect thepleats 313 so as to enhance the tensile strength of the bent segment of themain belt body 31. - With further reference to
FIG. 3 , the method of manufacturing the inflatable device is illustrated as follows. - The first and
second sheet sections second sheet sections strengthening belt 4 is further welded at the binding part of the first andsecond sheet sections second sheet sections - The
main belt body 31 and the reinforcingmember 33 of eachpull belt 3 are made of non-extendible elongated cloth. For eachpull belt 3, thepleats 313 of themain belt body 31 are formed by sewing at the firstlengthwise end portion 311, so that the length of the firstlengthwise end portion 311 is shortened to result in the bent segment of themain belt body 31. The reinforcingmember 33 is also sewed to be secured to themain belt body 31. In the preferred embodiment, eachpull belt 3 has fourpleats 313, but the number of thepleats 313 may vary as required. Referring further toFIG. 4 , before being secured to the first andsecond sheet sections lengthwise end portions main belt body 31 of eachpull belt 3 are folded and secured respectively to twofixing belts 5 to thereby form an H-shaped structure for ensuring that a structural strength of the H-shaped structure is sufficient to bear the tension after the inflation of the inflatable device. Each of thefixing belts 5 is composed of a PVC layer and a cloth layer that has the same material as themain belt body 31. The cloth layer is sewed to a respective one of the folded first and secondlengthwise end portions main belt body 31, and the PVC layer is welded to a respective one of the first andsecond sheet sections - In addition, the inflatable device may be formed into different shapes in different applications, such as an inflatable slider for children. Each
pull belt 3 may be formed with a plurality of bent segments toward different directions. For instance, amain belt body 31 may have a plurality ofpleats 313 formed at the firstlengthwise end portion 311, and a plurality ofpleats 313 formed simultaneously at the secondlengthwise end portion 312. The crease portion of eachpleat 313 at the firstlengthwise end portion 311 extends transversely from the firstlengthwise end portion 311 toward the secondlengthwise end portion 312 and the crease portion of eachpleat 313 at the secondlengthwise end portion 312 extends transversely from the secondlengthwise end portion 312 toward the firstlengthwise end portion 311. As such, a plurality of bent segments can be formed in eachpull belt 3 indifferent directions. - To sum up, the shape of the inflatable device of the present invention has more flexibility of alteration due to the
pleats 313 on thepull belts 3. Moreover, the location of eachpleat 313 on eachpull belt 3 can be adjusted as required to result in different shapes of eachpull belt 3. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
