Description

防護裝置及其伸縮件Guard and its expansion joint

本新型係關於一種防護裝置及其伸縮件，特別是一種可適用於不同尺寸物件之防護裝置及其伸縮件。The present invention relates to a guard device and a telescopic member thereof, and more particularly to a guard device and a telescopic member thereof that can be applied to articles of different sizes.

在運輸電子裝置的過程中，為了防止電子裝置受到碰撞，通常會使用防護裝置包圍電子裝置的周圍。電子裝置的外觀各形各色，故對於不同外形的電子裝置通常需要不同尺寸的防護裝置，也因此需要不同的製造模具或治具製作不同尺寸的防護結構。然而，如此的做法會造成模具或治具之開模成本的增加。In the process of transporting electronic devices, in order to prevent the electronic device from being bumped, a guard device is usually used to surround the periphery of the electronic device. The appearance of electronic devices varies from one color to another. Therefore, different sizes of electronic devices generally require different sizes of protective devices, and thus different manufacturing molds or jigs are required to fabricate protective structures of different sizes. However, such an approach would result in an increase in the cost of mold opening of the mold or jig.

因此，有業者於防護裝置中設置可伸縮的風箱形伸縮件，以因應各種不同尺寸的電子裝置。然而，風箱形的側面為連續Z字形，故如此之伸縮件的伸縮範圍常會不易固定在使用者想要的尺寸。尤其是常會發生伸縮件之伸縮範圍變得過大，而發生防護裝置與電子裝置鬆脫的情形。Therefore, the manufacturer provides a retractable bellows-shaped telescopic member in the guard device to respond to various sizes of electronic devices. However, the side of the bellows is a continuous zigzag shape, so that the telescopic range of the telescopic member is often difficult to fix to the size desired by the user. In particular, it is often the case that the telescopic range of the telescopic member becomes excessively large, and the guard device and the electronic device are loosened.

有鑑於以上的問題，本新型提出一種防護裝置及其伸縮件，其收攏狀態及伸展狀態不會輕易變動，藉以解決防護裝置與物件鬆脫之問題。In view of the above problems, the present invention proposes a guard device and a telescopic member thereof, and the collapsed state and the extended state are not easily changed, thereby solving the problem that the guard device and the object are loose.

本新型揭露一種防護裝置，用以放置於一物件。防 護裝置包括二連接件及二伸縮件。二伸縮件連接於二連接件之間而與二連接件圍繞形成一容置空間，容置空間用以供物件放置。各伸縮件具有一收攏狀態及一伸展狀態，且包括一第一塊材、一第二塊材及二第一連接材。第一塊材具有一第一連接部。第二塊材具有彼此分離之二第二連接部，且具有一第一凹部位於二第二連接部之間。二第一連接材分別具有相對之一第一端及一第二端。二第一端彼此相連且連接至第一連接部。二第二端彼此分離且分別連接至二第二連接部。各第一端至各第二端之長度的二倍大於二第二連接部之直線距離。於收攏狀態時，各第一連接材至少部分位於第一凹部內。於伸展狀態時，各第一連接材位於第一凹部外。The present invention discloses a guard for placing on an object. Defense The protection device comprises two connecting members and two telescopic members. The two telescopic members are connected between the two connecting members to form an accommodating space around the two connecting members, and the accommodating space is used for the objects to be placed. Each of the telescopic members has a collapsed state and an extended state, and includes a first block, a second block, and two first connectors. The first piece has a first connection. The second block has two second connecting portions separated from each other and has a first recess between the two second connecting portions. The two first connecting materials respectively have a first end and a second end. The two first ends are connected to each other and to the first connection. The second ends are separated from each other and connected to the second connection portions, respectively. Two times the length of each of the first ends to the second ends is greater than the linear distance of the two second connecting portions. In the collapsed state, each of the first connecting members is at least partially located in the first recess. In the extended state, each of the first connecting members is located outside the first recess.

本新型還揭露一種伸縮件，具有一收攏狀態及一伸展狀態。伸縮件包括一第一塊材、一第二塊材及二連接材。第一塊材具有一第一連接部。第二塊材具有彼此分離之二第二連接部，且具有一凹部位於二第二連接部之間。二連接材分別具有相對之一第一端及一第二端。二第一端彼此相連且連接至第一連接部。二第二端彼此分離且分別連接至二第二連接部。各第一端至各第二端之長度的二倍大於二第二連接部之直線距離。於收攏狀態時，各連接材至少部分位於凹部內。於伸展狀態時，各連接材位於凹部外。The present invention also discloses a telescopic member having a collapsed state and an extended state. The telescopic member comprises a first block, a second block and two connecting materials. The first piece has a first connection. The second block has two second connecting portions separated from each other and has a recess between the two second connecting portions. The two connecting materials respectively have a first end and a second end. The two first ends are connected to each other and to the first connection. The second ends are separated from each other and connected to the second connection portions, respectively. Two times the length of each of the first ends to the second ends is greater than the linear distance of the two second connecting portions. In the collapsed state, each of the connecting members is at least partially located in the recess. In the extended state, each of the connecting materials is located outside the recess.

根據本新型之防護裝置及其伸縮件，能夠藉由各連接材之各第一端至各第二端之長度的二倍大於第二塊材之二第 二連接部之直線距離，使得伸縮件於收攏狀態時，各連接材不易從凹部內離開，而令第一塊材及第二塊材不會過於輕易發生彼此距離的變化。而且，伸縮件處於伸展狀態時，第一塊材及第二塊材之距離較處於收攏狀態時遠，且各連接材不易再回到凹部內，而也令第一塊材及第二塊材不會過於輕易發生彼此距離的變化。因此，伸縮件之第一塊材及第二塊材能夠有兩段不同的距離狀態，且在伸縮件於收攏狀態及伸展狀態時，皆不會過於輕易地改變第一塊材及第二塊材間之距離，而能解決防護裝置與物件鬆脫之問題。According to the protection device of the present invention and the telescopic member thereof, the length from the first end to the second end of each connecting material can be greater than two times the second block The linear distance between the two connecting portions is such that when the telescopic member is in the folded state, the connecting materials are not easily separated from the concave portion, and the first block and the second block are not too easily changed in distance from each other. Moreover, when the telescopic member is in the extended state, the distance between the first block and the second block is farther than when the telescopic member is in the folded state, and the connecting materials are not easily returned to the concave portion, and the first block and the second block are also made. It is not too easy to change the distance from each other. Therefore, the first block and the second block of the telescopic member can have two different distance states, and the first block and the second block are not changed too easily when the telescopic member is in the folded state and the extended state. The distance between the materials can solve the problem that the protection device and the object are loose.

以上之關於本新型內容之說明及以下之實施方式之說明係用以示範與解釋本新型之精神與原理，並且提供本新型之專利申請範圍更進一步之解釋。The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the spirit and principles of the present invention, and to provide further explanation of the scope of the present patent application.

FIG. 1A is a perspective view showing a first object 21 placed on the shielding device 1 , 1 ′ according to an embodiment of the present invention, and FIG. 1B is a view showing the protection according to an embodiment of the present invention. A perspective view of the second object 22 is placed on the device 1, 1'. The length L1 of the first article 21 is smaller than the length L2 of the second article 22. Alternatively, the user can adjust the width of the first member 21 or the second member 22 by adjusting the distance between the guards 1 and 1'. In the present embodiment, one guard 1 protects one side of the first object 21 or the second object 22, and the other guard 1' protects the first The other side of an object 21 or second object 22. The first item 21 and the second item 22 may be items to be protected by the guard, such as an electronic device. Since the structure of the guard 1 and the guard 1' is similar, only the guard 1 will be described below, and the guard 1' will not be described.

防護裝置1包括二連接件11、二伸縮件12及二套設件13。二伸縮件12交錯連接於二連接件11之間而與二連接件11圍繞形成一容置空間10。容置空間10用以供第一物件21或第二物件22放置。各套設件13分別設置於各連接件11，且用以套設於第一物件21或第二物件22。各伸縮件12具有一收攏狀態及一伸展狀態。當伸縮件12處於收攏狀態時，如第1A圖所示，容置空間10能夠供第一物件21放置。當伸縮件12處於伸展狀態時，如第1B圖所示，容置空間10能夠供第二物件22放置。此外，伸縮件12之結構除了可應用於防護裝置1上，還可應用於其他需要調整長度的物體上。The protection device 1 comprises two connecting members 11 , two telescopic members 12 and two sleeve members 13 . The two telescopic members 12 are alternately connected between the two connecting members 11 to form an accommodating space 10 with the two connecting members 11 . The accommodating space 10 is for placing the first object 21 or the second object 22. The sleeves 13 are respectively disposed on the connecting members 11 and are sleeved on the first object 21 or the second object 22 . Each of the telescopic members 12 has a collapsed state and an extended state. When the telescopic member 12 is in the folded state, as shown in FIG. 1A, the accommodating space 10 can be placed for the first object 21. When the telescopic member 12 is in the extended state, as shown in FIG. 1B, the accommodating space 10 can be placed for the second object 22. Further, the structure of the telescopic member 12 can be applied to other objects that need to be adjusted in length, in addition to being applied to the guard 1.

請參照第2A圖、第2B圖及第2C圖，第2A圖及第2B圖繪示第1A圖之防護裝置1之伸縮件12處於收攏狀態之側視圖，第2C圖繪示第1B圖之防護裝置1之伸縮件12處於伸展狀態之側視圖。以下將說明各伸縮件12的詳細結構。為了避免圖式內之元件符號過於複雜，故將第1A圖之防護裝置1之伸縮件12處於收攏狀態之側視圖分為第2A圖及第2B圖繪示。由於第2A圖、第2B圖及第2C圖上下實質上對稱，且為避免圖式過於複雜，故重覆的元件符號僅標示於單側。Please refer to FIG. 2A, FIG. 2B and FIG. 2C. FIG. 2A and FIG. 2B are side views showing the telescopic member 12 of the guard device 1 of FIG. 1 in a collapsed state, and FIG. 2C is a view of FIG. The side view of the telescoping member 12 of the guard 1 is in an extended state. The detailed structure of each of the telescopic members 12 will be described below. In order to avoid the component symbol in the drawing being too complicated, the side view in which the telescopic element 12 of the guard 1 of FIG. 1 is in the folded state is divided into 2A and 2B. Since the 2A, 2B, and 2C are substantially symmetrical above and below, and the pattern is too complicated to be complicated, the repeated component symbols are only indicated on one side.

伸縮件12包括一第一塊材121、一第二塊材122及二連接材123。第一塊材121具有一第一連接部1211。第二塊材122具有彼此分離之二第二連接部1221，且具有一凹部1222位於二第二連接部1221之間。二連接材123分別具有相對之一第一端1231及一第二端1232。二第一端1231彼此相連且連接至第一連接部1211。二第二端1232彼此分離且分別連接至二第二連接部1221。各第一端1231至各第二端1232之長度L3的二倍大於二第二連接部1221之直線距離L4。如第2A圖及第2B圖所示，於收攏狀態時，各連接材123至少部分位於凹部1222內。如第2C圖所示，於伸展狀態時，各連接材123位於凹部1222外。The telescopic member 12 includes a first block 121, a second block 122 and two connecting members 123. The first piece 121 has a first connecting portion 1211. The second block 122 has two second connecting portions 1221 separated from each other, and has a recess 1222 between the two second connecting portions 1221. The two connecting members 123 respectively have a first end 1231 and a second end 1232. The two first ends 1231 are connected to each other and to the first connection portion 1211. The second ends 1232 are separated from each other and connected to the second connection portions 1221, respectively. The length L3 of each of the first ends 1231 to the second ends 1232 is greater than the linear distance L4 of the second and second connecting portions 1221. As shown in FIGS. 2A and 2B, in the collapsed state, each of the connecting members 123 is at least partially located in the recess 1222. As shown in FIG. 2C, in the extended state, each of the connecting members 123 is located outside the recess 1222.

於第2A圖及第2B圖中，即伸縮件12於收攏狀態時，由於各第一端1231至各第二端1232之長度L3的二倍大於二第二連接部1221之直線距離L4，且各連接材123位於凹部1222內，故各連接材123不易從凹部1222內離開。因此，伸縮件12處於收攏狀態時，不會過於輕易發生第一塊材121及第二塊材122之距離的變化。In the 2A and 2B drawings, when the telescopic member 12 is in the folded state, the length L3 of each of the first ends 1231 to the second ends 1232 is greater than the linear distance L4 of the second connecting portions 1221, and Since the respective connecting members 123 are located in the recessed portion 1222, the respective connecting members 123 are less likely to be separated from the inside of the recessed portion 1222. Therefore, when the telescopic member 12 is in the folded state, the change in the distance between the first block 121 and the second block 122 does not occur too easily.

當以一定力道拉開第一塊材121及第二塊材122時，會使各連接材123產生一定程度的變形，使各連接材123被拉至凹部1222外，且各連接材123會相對於第一塊材121及第二塊材122旋轉。藉此使伸縮件12處於第2C圖所示之伸展狀態。而由於各第一端1231至各第二端1232之長度L3的二倍大於二第二連接部1221之直線距離L4，使得各連接材123不易再回到 凹部1222內。另外，伸縮件12處於伸展狀態時，二連接材123之二第一端1231會彼此抵靠，甚至會產生被壓縮的區域1231a。如此使得各連接材123不會繼續相對於第一塊材121旋轉，進而使得第一塊材121不會繼續被拉離第二塊材122。因此，伸縮件12處於伸展狀態時，第一塊材121及第二塊材122之距離較處於收攏狀態時遠，且不會過於輕易發生第一塊材121及第二塊材122之距離的變化。When the first block 121 and the second block 122 are pulled apart by a certain force, the connecting members 123 are deformed to a certain extent, so that the connecting members 123 are pulled out of the recess 1222, and the connecting members 123 are opposite. The first block 121 and the second block 122 are rotated. Thereby, the stretchable member 12 is in the extended state shown in Fig. 2C. Since the length L3 of each of the first ends 1231 to the second ends 1232 is greater than the linear distance L4 of the second connecting portions 1221, the connecting members 123 are not easily returned. Inside the recess 1222. In addition, when the telescopic member 12 is in the extended state, the first ends 1231 of the two connecting members 123 abut each other, and even the compressed region 1231a is generated. This causes the respective connecting members 123 to not continue to rotate relative to the first block 121, so that the first block 121 does not continue to be pulled away from the second block 122. Therefore, when the telescopic member 12 is in the extended state, the distance between the first block 121 and the second block 122 is farther than when it is in the folded state, and the distance between the first block 121 and the second block 122 is not too easy to occur. Variety.

當以一定力道F推壓第一塊材121及第二塊材122以令二者彼此接近時，也會使各連接材123產生一定程度的變形，使各連接材123推回凹部1222內，藉此使伸縮件12處於第2A及第2B圖圖所示之收攏狀態。因此，處於收攏狀態或伸展狀態之伸縮件12不會過於輕易發生狀態的變化。When the first block 121 and the second block 122 are pressed by a certain force F to bring them closer to each other, the connecting members 123 are also deformed to a certain extent, so that the connecting members 123 are pushed back into the recess 1222. Thereby, the expansion/contraction member 12 is in the collapsed state shown in FIGS. 2A and 2B. Therefore, the telescopic member 12 in the collapsed state or the extended state does not change the state too easily.

於製作本實施例之伸縮件時，能夠將材質例如為發泡材料之主塊材120切割劃分成第一塊材121、第二塊材122及二連接材123。如第2A及第2B圖圖所示，主塊材120具有相對二側面1200且具有二第一切割面1201、二第二切割面1202、二第三切割面1203及二第四切割面1204。各連接材123由各第一切割面1201、各第二切割面1202、各第三切割面1203及各第四切割面1204切割而成。When the elastic member of the present embodiment is produced, the main block 120 of a material such as a foamed material can be cut into the first block 121, the second block 122, and the two connecting members 123.

綜上所述，本新型之防護裝置及其伸縮件，能夠藉由各連接材之各第一端至各第二端之長度的二倍大於第二塊材 之二第二連接部之直線距離，使得伸縮件於收攏狀態時，各連接材不易從凹部內離開，而令第一塊材及第二塊材不會過於輕易發生彼此距離的變化。而且，伸縮件處於伸展狀態時，第一塊材及第二塊材之距離較處於收攏狀態時遠，二連接材之二第一端會彼此抵靠而使第一塊材不會繼續被拉離第二塊材，且各連接材不易再回到凹部內，而也令第一塊材及第二塊材不會過於輕易發生彼此距離的變化。因此，伸縮件之第一塊材及第二塊材能夠有兩段不同的距離狀態，且在伸縮件於收攏狀態及伸展狀態時，皆不會過於輕易地改變第一塊材及第二塊材間之距離，而能解決防護裝置與物件鬆脫之問題。再者，伸縮件能夠包括更多塊材及連接材，而能夠具有更多種伸展狀態，伸縮件之塊材間的距離能夠有更多段不同的狀態，以因應更多種尺寸之物件的需求。In summary, the protection device of the present invention and the telescopic member thereof can be doubled by the length of each of the first ends to the second ends of the connecting materials. The linear distance of the second connecting portion is such that when the telescopic member is in the folded state, the connecting materials are not easily separated from the concave portion, so that the first block and the second block are not too easily changed in distance from each other. Moreover, when the telescopic member is in the extended state, the distance between the first block and the second block is farther than when the telescopic member is in the folded state, and the first ends of the two connecting materials abut each other so that the first block does not continue to be pulled. The second block is not easily returned to the recess, and the first block and the second block are not too easily changed from each other. Therefore, the first block and the second block of the telescopic member can have two different distance states, and the first block and the second block are not changed too easily when the telescopic member is in the folded state and the extended state. The distance between the materials can solve the problem that the protection device and the object are loose. Furthermore, the telescopic member can include more blocks and connecting materials, and can have more kinds of stretched states, and the distance between the blocks of the telescopic members can have more different states to meet the requirements of objects of more sizes. demand.
