A valve (34) is normally closed between the concave compartment and the slot compartment. When the valve rod is moved from a first position toward a second position, the valve is allowably to be pushed off by the valve rod, and the fluid located in the chamber is discharged from the concave compartment and the opening via the slot compartment, so that the gas cushion or the bag body is formed in a non-dilation state.
Description
- The invention relates to a structure design of a breast pad, in particular relates to a gas cushion (or a bag body) combined with a pump and a relief valve so as to control an expansion or compression state of the gas cushion (or the bag body).
- Underwear or brassieres utilized with woven fabrics to cover and support breasts are known as conventional skills. In order to increase visual artistic and shaping effects of brassieres or to promote conditions such as sagging breast or expansion breast, in conventional skills a combination of a breast pad and underwear or brassiere is disclosed to upwardly and concentratedly assist the underwear or the brassiere in supporting the breasts.
- Besides, in conventional skills an inflatable breast pad structure is disclosed, capable of dimensionally adjusting the breast pad in accordance with users' actual requirements or positions.
- Such an inflatable breast pad generally is a dilatable or compressible breast pad body disposed with a pump or a gas valve. A user can operate the pump or the gas valve to allow an external air to enter into an interior of the breast pad body, thereby forming the breast pad body in a dilation state. In other cases, a body is also configured with a gas bleed valve and a push-press bar disposed on the gas bleed valve, and the push-press bar is also combined with a spring, so that the spring drives a head upper end of the push-press bar to normally close a vent of the gas bleed valve, thereby preventing the air located inside the body from leakage. Besides, when the user holds the push-press bar to open the vent of the gas bleed valve for discharging the air located inside the body, the body is returned to an initial flat (or a compression) type.
- Representatively speaking, the above-mentioned reference data reveal the conditions of usage and structural design of the inflatable breast pad or other components connected therewith. If the structure and above-described applications of the inflatable breast pad or other components (e.g., the pump and the gas bleed valve) connected therewith can be properly redesigned and reconsidered, the use pattern and the application conditions of the inflatable breast pad can be advancedly altered and therefore distinguished from conventional methods. In fact, the breast pad is not only provided with adjustable dimension and enhanced visual artistic effect to meet users' actual requirements, but also the breast pad can have efficacy of simplified structure or operation convenience.
- In view of this, the main purpose of the invention is to provide an improved breast pad structure with efficacy of simplified structure and operation convenience. The breast pad structure includes a flexible gas cushion (or a bag body) which is defined with a reciprocally expandable and compressible chamber and configured with a pump and a relief valve. The pump includes a channel communicated with the chamber so that a fluid is allowed to enter into the chamber through the channel to form the gas cushion (or the bag body) in a dilation state. The relief valve is configured with a concave compartment, a slot compartment communicated with the concave compartment, and a valve rod movable between a first position and a second position. A valve is normally closed between the concave compartment and the slot compartment. When the valve rod is moved from the first position toward the second position, the valve is allowably to be pushed off by the valve rod, and the fluid located in the chamber is discharged from the concave compartment and the opening via the slot compartment, so that the gas cushion (or the bag body) is formed in a non-dilation (or compression) state.
- According to the improved breast pad structure of the invention, the concave compartment of the relief valve comprises a first concave compartment and a second concave compartment, and a through hole is formed between the first concave compartment and the second concave compartment of the concave compartment, so that the first concave compartment and the second concave compartment are formed of a communication type. The valve rod, corresponding to the first concave compartment and the second concave compartment of the concave compartment, comprises a head portion, an elastic device and a shoulder portion, in which the head portion and the elastic device are combined in the first concave compartment of the concave compartment, and the shoulder portion located inside the second concave compartment of the concave compartment is utilized to normally close the through hole. A state of the through hole to be closed by the shoulder portion of the valve rod can be removed unless the valve rod is moved toward the second position, so that the through hole of the relief valve is formed of an open type.
- The second concave compartment of the concave compartment is formed with a passage which enables the second concave compartment of the concave compartment and the slot compartment of the relief valve to form a communication type. An elastic body arranged in the slot compartment of the relief valve is utilized to drive the valve to normally close the passage of the concave compartment. Accordingly, the air or gas flow located in the chamber cannot be discharged from the slot compartment of the relief valve, the passage and the second concave compartment of the concave compartment, the through hole, and the first concave compartment of the concave compartment. The slot compartment of the relief valve and the passage of the concave compartment are formed in a passage-way state unless the valve is pushed off by the valve rod.
- According to the improved breast pad structure of the invention, the slot compartment of the relief valve is configured with at least one slit, so that the fluid located in the chamber is allowed to enter into the slot compartment of the relief valve via the slit. The concave compartment (or the first concave compartment) is configured with at least one opening, so that the first concave compartment and an exterior are constantly formed of an open type (or a passage-way state) via the opening. When the slot compartment of the relief valve, the passage and the concave compartment are formed in the opening state, the air or the gas flow can be discharged from the opening of the concave compartment.

Figs. 1 ,2 and3 , an improved breast pad structure of the invention comprises a flexible gas cushion (or a bag body) which is generally denoted by areference number 10. The gas cushion (or the bag body) 10 is a combination of twosheathing sheets sheathing sheet 11 includes anouter layer 11 a and aninner layer 11 b, and thesheathing sheet 12 includes anouter layer 12a and aninner layer 12b. Theouter layer 11 a and theinner layer 11 b are combined to form thesheathing sheet 11, and theouter layer 12a and theinner layer 12b are combined to form thesheathing sheet 12. The twosheathing sheets compressible chamber 13. In this embodiment, theouter layers sheathing sheets inner layer sheathing sheet - In
Figs. 1 ,2 and3 , it is also illustrated that the gas cushion (or the bag body) 10 is configured with apump 20 and arelief valve 30. In the adopted embodiment, thepump 20 and therelief valve 30 are configured on thesheathing sheet 12. Thepump 20 is defined with areaction chamber 21 and apumping hole 22 communicated thereaction chamber 21 to an exterior. Accordingly, with the operation between compression and releasing of thepump 20, thereaction chamber 21 can generate reciprocal contraction and expansion states, so that an external fluid can be drawn into thereaction chamber 21 through thepumping hole 22 of thepump 20. - Referring to
Figs. 2 and3 and in detailed description, thepump 20 further comprises asub-chamber 23. Thesub-chamber 23 communicated with thereaction chamber 21 is configured with avalve clack 24 and anelastic object 25 therein, in which theelastic object 25 enables thevalve clack 24 to normally close thepumping hole 22. - Refer to
Figs. 3 and 4 , inFig. 3 when thereaction chamber 21 situated in the compression state (shown by dotted lines) is returned to an initial dilation state (shown by real lines), the external fluid (e.g., air or gas flow) can be drawn into thereaction chamber 21 through thepumping hole 22. That is, the drawn external fluid pushes off thevalve clack 24 to enter into thesub-chamber 23 and thereaction chamber 21 of thepump 20, thereby forcing theelastic object 25 to store energy therein. - In
Fig. 4 , when thepump 20 is operated or pressed by a user (e.g., a condition denoted by arrows inFigs.4 ), theelastic object 25 releases the stored energy to drive thevalve clack 24 to close thesub-chamber 23 of thepump 20; meanwhile, the fluid located in thereaction chamber 21 of thepump 20 is forced to pass through thesub-chamber 23 of thepump 20 to enter into thechamber 13 of the gas cushion (or the bag body) 10, thereby forming the gas cushion (or the bag body) 10 (or the chamber 13) in the dilation state. - Concretely speaking, the
pump 20 further comprises achannel 26 communicated with thechamber 13 of the gas cushion (or the bag body) 10. In the adopted embodiment, thechannel 26 and thesub-chamber 23 of thepump 20 are formed of a communication type. When the user operates or presses thepump 20, the fluid located in thereaction chamber 21 is forced to open thechannel 26 of thepump 20, so that the gas flow can enter into thechamber 13 of the gas cushion (or the bag body) 10 via thechannel 26 of the pump 20 (as the condition illustrated inFig. 4 ). Accordingly, with the operation of thepump 20, the dilation or expansion of the gas cushion (or the bag body) 10 can be controlled in accordance with the actual requirement from the user. - Referring to

When thevalve rod 33 is moved from the first position toward the second position, thevalve 34 is forcedly pushed off by thevalve rod 33, and the fluid located in thechamber 13 is discharged from theconcave compartment 31 by passing theslot compartment 32, thereby forming the gas cushion (or the bag body) 10 in a non-dilation state. - In detailed description, the
concave compartment 31 of therelief valve 30 comprises a firstconcave compartment 31a and a secondconcave compartment 31 b, and athrough hole 35 is formed between the firstconcave compartment 31a and the secondconcave compartment 31b of theconcave compartment 31. Therefore, the firstconcave compartment 31a and the secondconcave compartment 31 b are formed of a communication type. Thevalve rod 33, corresponding to the firstconcave compartment 31 a and the secondconcave compartment 31b of theconcave compartment 31, comprises ahead portion 33a, anelastic device 36 and ashoulder portion 33b, in which thehead portion 33a and theelastic device 36 are combined in the firstconcave compartment 31 a of theconcave compartment 31, and theshoulder portion 33b is located inside the secondconcave compartment 31 b of theconcave compartment 31. Theelastic device 36 of thevalve rod 33 keeps theshoulder portion 33b of thevalve rod 33 to normally close the throughhole 35. A state of the throughhole 35 to be closed by theshoulder portion 33b of thevalve rod 33 can be removed unless thevalve rod 33 is moved toward the second position, so that the throughhole 35 of therelief valve 30 is formed of an open type. - In
Fig. 5 , it is also illustrated that the secondconcave compartment 31 b of theconcave compartment 31 is formed with apassage 31 c, forming the secondconcave compartment 31 b of theconcave compartment 31 and theslot compartment 32 of therelief valve 30 of a communication type. Anelastic body 37 is arranged in theslot compartment 32 of therelief valve 30 to drive thevalve 34 to normally close thepassage 31c of theconcave compartment 31. Accordingly, the air or gas flow located in thechamber 13 cannot be discharged from theslot compartment 32 of therelief valve 30, thepassage 31c and the secondconcave compartment 31 b of theconcave compartment 31, the throughhole 35, and the firstconcave compartment 31a of theconcave compartment 31. Theslot compartment 32 of therelief valve 30 and thepassage 31c of theconcave compartment 31 can be formed in a passage-way state unless thevalve 34 is pushed off by thevalve rod 33 of therelief valve 30. - In the adopted embodiment, the
slot compartment 32 of therelief valve 30 is configured with at least oneslit 32a, allowing the fluid located in thechamber 13 to enter into theslot compartment 32 of therelief valve 30 via theslit 32a.

Figs. 5 and 6 , the concave compartment 31 (or the firstconcave compartment 31 a) is configured with at least oneopening 38, constantly forming the firstconcave compartment 31 a and the exterior as an open type (or a passage-way state) via theopening 38. When theslot compartment 32 of therelief valve 30, thepassage 31c and theconcave compartment 31 are formed in the opening state, the air or the gas flow can be discharged from theopening 38 of theconcave compartment 31. - Concretely speaking, when the
valve rod 33 operated by the user is moved from the first position toward the second position, thevalve rod 33 forces theelastic device 36 to store energy therein and drives theshoulder portion 33b to remove the state of the throughhole 35 to be closed by theshoulder portion 33b of thevalve rod 33, so that the throughhole 35 of therelief valve 30 is formed of an open type. Further, as illustrated inFig. 6 , thevalve rod 33 downwardly presses on thevalve 34, so that theelastic body 37 is equally formed in a stored-energy state. Therefore, when thevalve rod 33 downwardly presses on thevalve 34, the state of thepassage 31 c to be closed by thevalve 34 is equally removed, so that theslit 32a, theslot compartment 32, thepassage 31 c, the secondconcave compartment 31b, the throughhole 35, the firstconcave compartment 31a and theopening 38 are formed of a passage-way state. The user can press the gas cushion (or the bag body) 10 to discharge the air located inside thechamber 13 from the above-described passage ways and theopening 38, thus to adjust the dimension of the gas cushion (or the bag body) 10, or to return the gas cushion (or the bag body) 10 to an initial flat shape. - Referring to
Fig. 7 , a derivate embodiment of the invention is illustrated, in which thepump 20 and therelief valve 30 are formed of an integral type. It can be understood that the operations or motions of the gas cushion (or the bag body) 10, thepump 20 and therelief valve 30 are the same as that mentioned in the above description. - Referring to
Fig. 8 , an application of the invention combined with an underwear 40 (or a brassiere) is illustrated, in which the gas cushion (or the bag body) 10 is installed inside theunderwear 40 through anopening 41 formed thereon. - Representatively speaking, the invention provides an improved breast pad structure with a size-adjustable breast pad. In comparison with conventional skills, the invention provides the considerations and advantages as follows.
- Firstly, the structure design and configuration relation of the gas cushion (or the bag body) 10 or components (e.g., a pump, a relief valve, etc.) connected therewith have been redesigned and reconsidered, providing innovated use patterns and applications capable of being distinguished from conventional skills. Actually, the invention also provides various functions of simplified structures and visual artistic effect.
- Secondly, the invention provides a simplified operation effect in accordance with the following conditions. For example, the gas cushion (or the bag body) 10 is combined with the
