Definitions
- the present invention relates to a protective case for fan, and more particularly to a protective case having a case body internally provided with first and second retaining portions, so that the same protective case can be conveniently used to stably pack differently sized fans and the cost of manufacturing differently sized protective cases can be saved.
- Chipsets for different electronic elements provide constantly increased computing speed and the number of chips included in different chipsets also increases constantly.
- heat produced by the chips during the operation thereof also increases with the increased number of chips.
- the produced heat must be timely removed from the electronic elements to avoid adverse influences on the performance thereof, such as slowed processing speed, burned-out or failed electronic elements. Therefore, heat dissipation has become a very important issue in the electronic industry.
- a fan has been widely adopted as a heat dissipating device to remove the heat produced by the operating electronic elements.
- the fan is subject to invasion by dust and foreign matters in the process of transporting, handling, or selling the fan.
- the invaded dust and foreign matters would inevitably move from the operating fan to different electronic elements, resulting in short circuit and burnout of the electronic elements.
- a protective case for fan has been developed.
- a conventional protective case for fan includes a case cover 10 and a case body 12 .
- the case body 12 internally defines a receiving space 121 for receiving a fan 14 therein.
- a space 16 between an inner wall surface of the case body 12 and an outer periphery of the fan 14 is reserved in the receiving space 121 to facilitate easy and convenient positioning of the fan 14 into the receiving space 121 in the case body 12 .
- the case cover 10 can be closed onto an open top of the case body 12 to seal the receiving space 121 .
- fans can be generally divided into two types according to their sizes, namely, large-size fans and small-size fans.
- an operator Before packing a fan 14 in the case body 12 , an operator has to verify first whether the fan 14 being handled is a large-size fan or a small-size fan. In the event of a large-size fan, the operator has to select a corresponding large-size case body 12 for packing the large-sized fan 14 . Then, the fan 14 is moved toward the case body 12 until the fan 14 is positioned on a bottom of the receiving space 121 . Finally, the case cover 10 is closed onto the case body 12 .
- the operator has to select a corresponding small-size case body 12 for packing the small-size fan 14 .
- the fan 14 is moved toward the case body 12 until the fan 14 is positioned on a bottom of the receiving space 121 .
- the case cover 10 is closed onto the case body 12 .
- the conventional protective cases can effectively protect the fans against invasion by dust and foreign matters
- the conventional protective cases must be manufactured into at least two different sizes separately for packing the large-size and the small-size fans. It requires increased cost to manufacture differently sized protective cases, and it is troublesome for an operator to verify and select a correctly sized protective case each time a fan is to be packed.
- the fan 14 packed in the conventional protective case is not firmly held in place and tends to vibrate or shake during transportation or handling thereof. Therefore, the fan 14 is subject to displacement in and collision with the protective case and the case cover 10 is subject to loosening from the case body 12 . In some worse conditions, the fan 14 is damaged in the protective case due to such vibration or shaking.
- Foam materials and other shock-absorbing materials have been used to stuff the reserved space 16 , so as to prevent the fan 14 from damage caused by displacement in and collision with the case body 12 .
- the stuffing brings other problems, such as increased overall weight of the packed fan and environmental pollution caused by discarded stuffing.
- the protective case is made of a transparent material and in the form of a hang card for displaying the fan packed therein for sale.
- the foam material or other shock-absorbing material stuffed in the protective case would no doubt have adverse influence on the aesthetic appearance of the fan being displayed in the protective case, making the fan less attractive to consumers.
- the conventional protective case for fan has the following disadvantages: (1) requiring increased manufacturing cost; (2) causing inconvenience in packing fans; (3) failing to firmly hold the fan in place; and (4) having low applicability.
- a primary object of the present invention is to provide a protective case for fan that can be manufactured at reduced cost.
- Another object of the present invention is to provide a protective case for fan that can provide enhanced locating effect to the fan packed therein.
- a further object of the present invention is to provide a protective case for fan that can be conveniently used to pack differently sized fans.
- the protective case for fan includes a case body having a closed bottom portion and a sidewall portion connected to and extended along a periphery of the bottom portion, so that a receiving space is defined in the case body between the bottom portion and the sidewall portion.
- Two first raised ribs are formed on the closed bottom portion adjacent to a first set of two opposite sides thereof, such that a first retaining portion is defined between the sidewall portion and one face of each of the first raised ribs facing toward the sidewall portion, and a second retaining portion is defined on another face of each of the first raised ribs facing away from the sidewall portion.
- a fan packed in the protective case can be more stably held in place, and the same protective case can be conveniently used to pack differently sized fans to save the cost of manufacturing differently sized protective cases.
- the protective case for fan includes a case body, a receiving space, and at least one set of two first raised ribs.
- the case body has a closed bottom portion and a sidewall portion connected to and extended along a periphery of the bottom portion.
- the receiving space is defined between the bottom portion and the sidewall portion, and has an open top portion opposite to the closed bottom portion.
- the two first raised ribs are formed on the closed bottom portion at a first set of two diagonally opposite corners thereof, and each of the first raised ribs includes a first and a second section located perpendicular to each other and adjacent to the sidewall portion, such that a first retaining portion is defined between the sidewall portion and one face of each of the first raised ribs facing toward the sidewall portion, and a second retaining portion is defined on another face of each of the first raised ribs facing away from the sidewall portion.

A protective case for fan includes a case body having a closed bottom portion and a sidewall portion extended along a periphery of the bottom portion, so that a receiving space is defined between the bottom and sidewall portions. A case cover can be closed onto an open top of the receiving space to seal the same. Two first raised ribs are formed on the closed bottom portion adjacent to two opposite sides thereof, such that first retaining portions are defined between the sidewall portion and faces of the first raised ribs facing toward the sidewall portion, and second retaining portions are defined on another faces of the first raised ribs facing away from the sidewall portion. By providing the first and second retaining portions, the same protective case can be conveniently used to stably pack differently sized fans to save the manufacturing cost of the protective case.
Description
- The present invention relates to a protective case for fan, and more particularly to a protective case having a case body internally provided with first and second retaining portions, so that the same protective case can be conveniently used to stably pack differently sized fans and the cost of manufacturing differently sized protective cases can be saved.
- Thanks to the prosperously developed electronic industry, various kinds of electronic elements now have upgraded performance to provide faster and faster computing and operating speed. Chipsets for different electronic elements provide constantly increased computing speed and the number of chips included in different chipsets also increases constantly. However, heat produced by the chips during the operation thereof also increases with the increased number of chips. The produced heat must be timely removed from the electronic elements to avoid adverse influences on the performance thereof, such as slowed processing speed, burned-out or failed electronic elements. Therefore, heat dissipation has become a very important issue in the electronic industry. Among others, a fan has been widely adopted as a heat dissipating device to remove the heat produced by the operating electronic elements.
- Generally, the fan is subject to invasion by dust and foreign matters in the process of transporting, handling, or selling the fan. The invaded dust and foreign matters would inevitably move from the operating fan to different electronic elements, resulting in short circuit and burnout of the electronic elements. To solve the problems caused by the dust-invaded fan, a protective case for fan has been developed.

FIGS. 1A and 1B . A conventional protective case for fan includes acase cover 10 and acase body 12. Thecase body 12 internally defines areceiving space 121 for receiving afan 14 therein. Aspace 16 between an inner wall surface of thecase body 12 and an outer periphery of thefan 14 is reserved in thereceiving space 121 to facilitate easy and convenient positioning of thefan 14 into thereceiving space 121 in thecase body 12. Thecase cover 10 can be closed onto an open top of thecase body 12 to seal thereceiving space 121. - Most of currently available fans can be generally divided into two types according to their sizes, namely, large-size fans and small-size fans. Before packing a
fan 14 in thecase body 12, an operator has to verify first whether thefan 14 being handled is a large-size fan or a small-size fan. In the event of a large-size fan, the operator has to select a corresponding large-size case body 12 for packing the large-sized fan 14. Then, thefan 14 is moved toward thecase body 12 until thefan 14 is positioned on a bottom of thereceiving space 121. Finally, thecase cover 10 is closed onto thecase body 12. - In the event of a small-size fan, the operator has to select a corresponding small-
size case body 12 for packing the small-size fan 14. Then, thefan 14 is moved toward thecase body 12 until thefan 14 is positioned on a bottom of thereceiving space 121. Finally, thecase cover 10 is closed onto thecase body 12. - Therefore, while the conventional protective cases can effectively protect the fans against invasion by dust and foreign matters, the conventional protective cases must be manufactured into at least two different sizes separately for packing the large-size and the small-size fans. It requires increased cost to manufacture differently sized protective cases, and it is troublesome for an operator to verify and select a correctly sized protective case each time a fan is to be packed.
- Moreover, with the
space 16 left in thereceiving space 121 between thefan 14 and thecase body 12, thefan 14 packed in the conventional protective case is not firmly held in place and tends to vibrate or shake during transportation or handling thereof. Therefore, thefan 14 is subject to displacement in and collision with the protective case and thecase cover 10 is subject to loosening from thecase body 12. In some worse conditions, thefan 14 is damaged in the protective case due to such vibration or shaking. Foam materials and other shock-absorbing materials have been used to stuff thereserved space 16, so as to prevent thefan 14 from damage caused by displacement in and collision with thecase body 12. However, the stuffing brings other problems, such as increased overall weight of the packed fan and environmental pollution caused by discarded stuffing. In some cases the protective case is made of a transparent material and in the form of a hang card for displaying the fan packed therein for sale. The foam material or other shock-absorbing material stuffed in the protective case would no doubt have adverse influence on the aesthetic appearance of the fan being displayed in the protective case, making the fan less attractive to consumers. - In brief, the conventional protective case for fan has the following disadvantages: (1) requiring increased manufacturing cost; (2) causing inconvenience in packing fans; (3) failing to firmly hold the fan in place; and (4) having low applicability.
- It is therefore tried by the inventor to develop an improved protective case for fan to overcome the above-mentioned disadvantages in the conventional protective case.
- A primary object of the present invention is to provide a protective case for fan that can be manufactured at reduced cost.
- Another object of the present invention is to provide a protective case for fan that can provide enhanced locating effect to the fan packed therein.
- A further object of the present invention is to provide a protective case for fan that can be conveniently used to pack differently sized fans.
- To achieve the above and other objects, the protective case for fan according to a first embodiment of the present invention includes a case body having a closed bottom portion and a sidewall portion connected to and extended along a periphery of the bottom portion, so that a receiving space is defined in the case body between the bottom portion and the sidewall portion. Two first raised ribs are formed on the closed bottom portion adjacent to a first set of two opposite sides thereof, such that a first retaining portion is defined between the sidewall portion and one face of each of the first raised ribs facing toward the sidewall portion, and a second retaining portion is defined on another face of each of the first raised ribs facing away from the sidewall portion.
- By providing the first and second retaining portions, a fan packed in the protective case can be more stably held in place, and the same protective case can be conveniently used to pack differently sized fans to save the cost of manufacturing differently sized protective cases.
- The protective case for fan according to a second embodiment of the present invention includes a case body, a receiving space, and at least one set of two first raised ribs. The case body has a closed bottom portion and a sidewall portion connected to and extended along a periphery of the bottom portion. The receiving space is defined between the bottom portion and the sidewall portion, and has an open top portion opposite to the closed bottom portion. The two first raised ribs are formed on the closed bottom portion at a first set of two diagonally opposite corners thereof, and each of the first raised ribs includes a first and a second section located perpendicular to each other and adjacent to the sidewall portion, such that a first retaining portion is defined between the sidewall portion and one face of each of the first raised ribs facing toward the sidewall portion, and a second retaining portion is defined on another face of each of the first raised ribs facing away from the sidewall portion. By providing the first and second retaining portions, a fan packed in the protective case can be more stably held in place, and the same protective case can be conveniently used to pack differently sized fans to save the cost of manufacturing differently sized protective cases.
