Description

Writing devices

The present invention relates to a device, and in particular to a writing device.

The current writing device is relatively large in size, so that the electronic device needs to leave a large space to store the writing device, which is inconvenient to store. In addition, a writing device with a smaller size is convenient to store but has a poor grip feel, which is inconvenient for users to use.

The present invention provides a writing device with better gripping feeling and convenient storage.

The writing device of the present invention is suitable for being received in a receiving slot. The writing device comprises a writing body, at least one movable cover, at least one supporting member and at least one elastic member. Each movable cover is movably connected to the writing body along a first axis. The supporting member is movably connected to the movable cover and the writing body. The elastic member is movably disposed between at least one movable cover and the writing device along the first axis. When the writing device is received in the receiving slot, the writing device is in a receiving state, and at least one elastic member accumulates elastic force. When the writing device leaves the receiving slot, the movable cover moves away from the writing body through the elastic force of the elastic member, so that the writing device is in a use state. The distance between an inner surface of the movable cover in the use state and an outer surface of the writing body is greater than the distance between the inner surface of the movable cover in the storage state and the outer surface of the writing body.

Based on the above, the movable cover of the writing device of the present invention can be moved relative to the writing body through the support member, so that the writing device can be switched between the use state and the storage state. When the writing device is stored in the storage slot and is in the storage state, the distance between the movable cover and the writing body is smaller, so that the volume of at least part of the writing device is reduced, which is conducive to storage. When the writing device is in the use state, the distance between the movable cover and the writing body is larger, and the volume of at least part of the writing device is increased to provide a better grip. In this way, the grip feel and storage convenience of the writing device can be improved.

Please refer to Figures 1 to 7 together. The writing device 100 includes a writing body 110, at least one movable cover, at least one supporting member, and at least one elastic member 140. In this embodiment, the number of movable covers is two, the number of supporting members is two, and the number of elastic members is two, but it is not limited thereto. In an embodiment not shown, the number of movable covers may be one. The two movable covers 120a, 120b are movably connected to the writing body 110 along a first axis L1. The supporting members 130a, 130b are movably connected to the corresponding movable covers 120a, 120b and the writing body 110.

The elastic member 140 is connected between the movable covers 120a, 120b and the writing body 110 along the first axis L1. The elastic member 140 is, for example, a spring. The elastic member 140 can be used to assist in fixing the movable covers 120a, 120b and the writing body 110, so that only one supporting member 130a, 130b is needed between the two movable covers 120a, 120b and the writing body 110 to support the movable covers 120a, 120b.

The writing device 100 can be stored in a receiving slot 200 (FIG. 5). The writing device 100 is, for example, an active touch pen, and the writing body 110 can be provided with a refill and a circuit board, but is not limited thereto. The receiving slot 200 can be, for example, located in an electronic device 300, and the electronic device 300 is, for example, a notebook computer, but is not limited thereto.

As shown in FIG3 , when the writing device 100 is outside the receiving slot 200, the writing device 100 is in a use state M1. The user's fingers hold the movable covers 120a and 120b to use the writing device 100. As shown in FIG5 , when the writing device 100 is stored in the receiving slot 200, the movable covers 120a and 120b are pressed by an inner wall 210 of the receiving slot 200 and move along the first axis L1, so that the writing device 100 is in a storage state M2. The elastic member 140 is compressed and accumulates elastic force. The supporting members 130a and 130b accumulate elastic force due to the compression of the elastic member 140. When the writing device 100 switches from the storage state M2 to the use state M1 (for example, the writing device 100 leaves the receiving slot 200 ), the movable covers 120 a and 120 b return to the position shown in FIG. 3 by the elastic force of the elastic member 140 .

As shown in FIG6 and FIG7, a distance D1 between an inner surface S2 of the movable cover 120a in the use state M1 and an outer surface S1 of the writing body 110 is greater than a distance D2 between an inner surface S2 of the movable cover 120a in the storage state M2 and an outer surface S1 of the writing body 110. That is, a total height D5 of the writing device 100 in the use state M1 is greater than a total height D6 of the writing device 100 in the storage state M2.

It can be seen that when the writing device 100 is in the storage state M2, at least a part of the volume of the writing device 100 is reduced, which is convenient for storage. When the writing device 100 is in the use state M1, at least a part of the volume of the writing device 100 is increased to provide the user with a better grip. In this way, the grip feel and storage convenience of the writing device 100 can be improved.

As shown in FIG. 2 , FIG. 6 and FIG. 7 , the outer surface S1 of the writing body 110 includes a first outer surface S11 and a second outer surface S12 facing each other. The inner surface S21 of the movable cover 120a faces the first outer surface S11, and the inner surface S22 of the movable cover 120b faces the second outer surface S12. The cross-sectional shape of the writing body 110 is a rectangle, and the cross-sectional shapes of the movable covers 120a and 120b are a U-shape. The two U-shaped openings P1 face the writing body 110. The two movable covers 120a and 120b surround the writing body 110. Since the cross-section of the writing body 110 is rectangular and the cross-section of the movable covers 120a and 120b is U-shaped, when the writing device 100 switches between the storage state M2 and the use state M1, the movable covers 120a and 120b move up and down the same distance along the first axis L1 relative to the writing body 110.

As shown in FIG2 , the writing body 110 includes at least one first connecting member 112, and each movable cover 120a, 120b includes two second connecting members 122. In this embodiment, the number of first connecting members 112 is four, two first connecting members 112 are located on the first outer surface S11, and two first connecting members 112 are located on the second outer surface S12, but the present invention is not limited thereto. As shown in FIG6 , the first connecting member 112 and the second connecting member 122 are staggered on a second axis L2. The first axis L1 is perpendicular to the second axis L2.

As shown in FIG. 2 , the supporting members 130a and 130b include a first portion 132, two second portions 134 and two third portions 136 connected in a bent manner. The supporting members 130a and 130b are in a C-shaped shape. The two second portions 134 are connected to the two ends of the first portion 132, and the two third portions 136 are connected to the two second portions 134, respectively. The second portion 134 is located between the first portion 132 and the corresponding third portion 136. The first portion 132 is movably connected to the first connecting member 112 of the writing body 110, and the two third portions 136 are connected to the two second connecting members 122 of the movable covers 120a and 120b, respectively. The C-shaped opening P2 of the supporting members 130a and 130b is located between the two third portions 136. As shown in FIG. 6 , the third portions 136 of the two supporting members 130 a and 130 b are staggered on the second axis L2 , that is, the two C-shaped openings P2 face in opposite directions.

The support member 130a is located between the inner surface S21 and the first outer surface S11, and the support member 130a is rotatably connected to the first connection member 112 on the first outer surface S11 of the writing body 110, and is connected to the second connection member 122 connected to the movable cover 120a. The support member 130b is located between the inner surface S22 and the second outer surface S12, and the support member 130b is rotatably connected to the first connection member 112 on the second outer surface S12 of the writing body 110, and is connected to the second connection member 122 connected to the movable cover 120b. When the writing device 100 switches between the use state M1 ( FIG. 6 ) and the storage state M2 ( FIG. 7 ), the two supporting members 130 a and 130 b move along with the two movable covers 120 a and 120 b.

The supporting members 130a and 130b of this embodiment are, for example, formed by bending a steel wire, but are not limited thereto. The supporting members 130a and 130b have a certain structural strength, and can ensure that when a certain part of the movable cover 120a and 120b is pressed, the supporting members 130a and 130b as a whole move toward the writing body 110, thereby driving the entire movable cover 120a and 120b to move.

As shown in FIG6 and FIG7, when the writing device 100 is to be switched from the use state M1 to the storage state M2, the user can press the two movable covers 120a and 120b to move the movable cover 120a along the first axis L1 toward the writing body 110 (i.e., downward), and the movable cover 120b moves along the first axis L1 toward the writing body 110 (i.e., upward). The two movable covers 120a and 120b move in opposite directions to approach the writing body 110 and press the corresponding two supporting members 130a and 130b and the two elastic members 140. As shown in FIG7, the writing device 100 is in the storage state M2 and can be stored in the receiving slot 200 (FIG. 5). The second connecting member 122 can contact the writing body 110.

As shown in FIG. 3 , FIG. 6 and FIG. 7 , when the writing device 100 leaves the receiving slot 200, the writing device 100 automatically switches from the storage state M2 to the use state M1. The two movable covers 120a and 120b move away from the writing body 110 along the first axis L1 by the elastic force of the corresponding two elastic members 140. The movable covers 120a move upward by the elastic force of the respective elastic members 140, and the movable covers 120b move downward by the elastic force of the respective elastic members 140. The movable covers 120a and 120b move to the position shown in FIG. 6 , at which time the writing device 100 is in the use state M1. Since the elastic member 140 has a certain elastic force and the supporting members 130a and 130b have a certain structural strength, when the user holds the writing device 100 in the use state M1 with normal force, the supporting members 130a and 130b can support the movable covers 120a and 120b, so that the movable covers 120a and 120b are maintained in the position shown in FIG. 6 without moving relative to the writing body 110.

In addition, as shown in FIG6 , the writing body 110 includes at least one first positioning post 118, and each movable cover 120a, 120b includes at least one second positioning post 128. The first positioning post 118 corresponds to the second positioning post 128. The number of the elastic members 140 in this embodiment is two, but not limited thereto. The number of the first positioning post 118 and the second positioning post 128 is two corresponding to the elastic member 140, but not limited thereto. One first positioning post 118 is located on the first outer surface S11, and the other first positioning post 118 is located on the second outer surface S12. One second positioning post 128 is located on the inner surface S21 of the movable cover 120a, and the other second positioning post 128 is located on the inner surface S22 of the movable cover 120b.

The elastic member 140 is connected to the first positioning post 118 and the second positioning post 128. The outer diameter of the elastic member 140 is closely matched to the inner diameter of the first positioning post 118 and the inner diameter of the second positioning post 128, so as to prevent the movable covers 120a and 120b from being pulled out of the writing body 110.

As shown in FIG. 2 , the writing device 100 further includes a cap 150. The cap 150 is connected to an end 114 of the writing body 110. The writing device 100 has a movable area A1 and a fixed area A2. The movable covers 120a, 120b, the supporting members 130a, 130b and the elastic member 140 are located in the movable area A1, and the cap 150 is located in the fixed area A2. The writing body 110 is at least partially located in the movable area A1. The height D3 of the cap 150 along the first axis L1 is greater than the height D4 of the receiving groove 200 along the first axis L1.

As shown in FIG. 5 , when the writing device 100 switches between the use state M1 and the storage state M2, the movable covers 120a and 120b move relative to the cap 150. When the writing device 100 is stored in the receiving slot 200, the fixed area A2 (cap 150) is exposed from the receiving slot 200 and is located outside the electronic device 300, and the movable area A1 (writing body 110 and movable covers 120a and 120b) is located in the receiving slot 200. The user can pull the cap 150 to take the movable area A1 of the writing device 100 out of the receiving slot 200 (electronic device 300), thereby improving the convenience of use of the writing device 100.

As shown in FIG6 and FIG7, the total width D7 of the writing device 100 of the present embodiment along the second axis L2 is, for example, 9 cm. The total height D5 of the movable area A1 (writing body 110 and movable covers 120a, 120b) along the first axis L1 in the storage state M2 is, for example, 6 cm, and the cross-sectional area of the movable area A1 is about 54 square centimeters. The total height D6 of the movable area A1 along the first axis L1 in the use state M1 is, for example, 9 cm, and the cross-sectional area of the movable area A1 is about 81 square centimeters. It can be seen that, compared with the writing device 100 in the use state M1, the height of the movable area A1 along the first axis L1 of the writing device 100 in the storage state M2 is reduced by 3 cm (for example, the two movable covers 120a and 120b move 1.5 cm respectively), and the cross-sectional area of the movable area A1 is reduced by about 33.33%. The volume of the movable area A1 in the storage state M2 is smaller than the volume of the movable area A1 in the use state M1.

In addition, the number of movable covers 120a, 120b, supporting members 130a, 130b and elastic members 140 is not limited to the present embodiment. In an embodiment not shown, the number of movable covers may be one (e.g., movable cover 120a), the number of supporting members may be two and the number of elastic members 140 may be two. The two supporting members are located between the movable cover 120a and the writing body 110. The third portions 136 of the two supporting members may be staggered on the second axis L2 so that the two C-shaped openings P2 face opposite directions. When viewed from the perspective of FIG. 6 , the two supporting members may cross each other to form a scissor-leg structure. The two elastic members may be located between the movable cover 120a and the writing body 110.

In summary, the movable cover of the writing device of the present invention can be moved relative to the writing body through the support member, so that the writing device can be switched between the use state and the storage state. When the writing device is stored in the storage slot and is in the storage state, the distance between the movable cover and the writing body is smaller, so that the volume of at least part of the writing device is reduced, which is conducive to storage. When the writing device is in the use state, the distance between the movable cover and the writing body is larger, and the volume of at least part of the writing device is increased to provide a better grip. In this way, the grip feel and storage convenience of the writing device can be improved.
