Abstract
An inflatable pad includes an inflatable pad body having a top layer, a bottom layer, and an annular surrounding layer interconnecting the top and bottom layers and cooperating with the top and bottom layers to define an inflatable space. A plurality of tubular reinforcing units are disposed in the inflatable space of the inflatable pad body. Each reinforcing unit has an annular outer surface having opposite polygonal attaching areas that face respectively the top and bottom layers of the pad body. A periphery of each of the polygonal attaching areas is attached fixedly to a corresponding one of the top and bottom layers of the pad body.
Description
- This application claims priority of Chinese Application No. 200620155256.0, filed on Dec. 22, 2006.
- 1. Field of the Invention
- The invention relates to an inflatable pad, more particularly to an inflatable pad having reinforcing units.
- 2. Description of the Related Art
- Referring to
FIG. 1 , a conventionalinflatable pad 5 is shown to include an inflatable pad body consisting of atop layer 50, abottom layer 51, and an annular surrounding layer (not shown) interconnecting the top andbottom layers bottom layers inflatable space 53, and a plurality of reinforcing belts 54 (only one is shown), each of which has opposite ends welded respectively and thermally to the top andbottom layers elliptical welding lines 55. Based on tests, during use, a relatively large stress acts at a location (E) of eachthermal welding line 55, and a relatively small stress acts at a location (F) of eachterminal welding line 55. As a result, theinflatable pad 5 easily splits at the location (E) of eachthermal welding line 55. - Therefore, the object of the present invention is to provide an inflatable pad that has reinforcing units capable of overcoming the aforesaid drawback of the prior art.
- According to the present invention, an inflatable pad comprises:
- an inflatable pad body having a top layer, a bottom layer, and an annular surrounding layer interconnecting the top and bottom layers and cooperating with the top and bottom layers to define an inflatable space; and
- a plurality of tubular reinforcing units disposed in the inflatable space of the inflatable pad body, each of the reinforcing units having an annular outer surface having opposite polygonal attaching areas that face respectively the top and bottom layers of the pad body, a periphery of each of the polygonal attaching areas being attached fixedly to a corresponding one of the top and bottom layers of the pad body.
- 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 fragmentary perspective view of a conventional inflatable bed; -
FIG. 2 is a perspective view showing the preferred embodiment of an inflatable pad according to the present invention; -
FIG. 3 is a partly exploded perspective view showing the preferred embodiment; -
FIG. 4 is a fragmentary assembled perspective view showing the preferred embodiment; -
FIG. 5 is a perspective view showing a reinforcing unit of the preferred embodiment; and -
FIG. 6 is a perspective view of a modified reinforcing unit. - Referring to
FIGS. 2 to 4 , the preferred embodiment of an inflatable pad according to the present invention is shown to include aninflatable pad body 1, and a plurality of reinforcingunits 4. In this embodiment, the inflatable pad is an inflatable bed. - The
inflatable pad body 1 has atop layer 11, abottom layer 12, and an annular surroundinglayer 13 interconnecting the top andbottom layers bottom layers inflatable space 10. - The reinforcing
units 4 are disposed in theinflatable space 10 of theinflatable pad body 1, and are arranged in an array. Referring toFIG. 5 , each reinforcingunit 4 has an annularouter surface 40 having opposite polygonal attachingareas 401 that face respectively the top andbottom layers periphery 41 of each polygonal attachingarea 401 is attached fixedly to a corresponding one of the top andbottom layers pad body 1 by thermal welding. In this embodiment, the attachingareas 401 of the annularouter surface 40 of each reinforcingunit 4 are hexagonal, i.e., have six sides. Preferably, for each reinforcingunit 4, twosides area 401 of the annularouter surface 40 are parallel to each other, are longer than the other ones of the sides thereof, and extend in a longitudinal direction of acorresponding reinforcing unit 4, thereby reinforcing bonding with the top andbottom layers area 401 of the annularouter surface 40 of each reinforcingunit 4 is chamfered at each of corners thereof, thereby minimizing stress concentrated at the corners. - Referring to
FIG. 6 , there is provided a modifiedreinforcing unit 4′, wherein each of the attachingareas 401′ of the annularouter surface 40′ is regular hexagonal. As such, each attachingarea 401′ has six identical sides that constitute theperiphery 41′ thereof. - 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.
