Description

Technical Field

[0001] This utility model belongs to the field of lint rollers, specifically relating to a handheld unit and a lint roller. Background Technology

[0002] Lint rollers use the stickiness of lint rollers to remove hair and dust from the surfaces of clothing, sofas, and other objects.

[0003] Existing lint rollers can be referenced from a lint roller disclosed in Chinese Patent No. CN202420157417.8, which uses a hand-held handle to roll the lint roller on the support over the surface of the object to be cleaned to achieve cleaning.

[0004] However, existing handles are usually fixed to the bracket in a one-piece molding process, making the lint roller a non-foldable T-shaped structure. This requires more space for the lint roller when it is not in use, such as in storage, transportation, or packaging environments, resulting in problems such as inconvenient storage, low transportation efficiency, and high packaging costs.

[0005] Therefore, there is an urgent need to design a lint roller that can be folded when not in use, thus making the structure more compact. Utility Model Content

[0009] The present invention is further configured such that: in the use state, the handle is flipped relative to the mounting bracket so that the middle part of the length of the handle is close to the mounting bracket to form a first folded state; and / or, in the second folded state, the handle is slid relative to the mounting bracket so that the middle part of the length of the handle is away from the connector to form the first folded state.

[0010] The present invention is further configured such that: the connecting track is provided with an unfolding position and a storage position; in the use state and the first folded state, the connector is located in the unfolding position; in the second folded state, the connector is located in the storage position.

[0011] The present invention is further configured such that: the unfolding position is located at the end of the handle, and the storage position is located in the middle of the length of the handle; the number of the unfolding position and the storage position is one, or the number of the unfolding position is two, the number of the storage position is one, and the storage position is located between the two unfolding positions.

[0012] The present invention is further configured such that: the length of the mounting bracket is s1, and the length of the handle is s2, wherein s1 / 2≤s2.

[0013] The present invention is further configured such that: a sliding positioning component is provided on the handle, the sliding positioning component is used to restrict the connector from sliding toward the middle of its length away from the handle in the second folded state.

[0014] The present invention is further configured such that: the mounting bracket is provided with a positioning plane at the connector, and one end of the handle is provided with a positioning arc surface; during the process of the handle being flipped from the use state to the first folded state, the positioning plane and the positioning arc surface are always tangent and / or abutting each other; the connector is provided with a first rotating positioning member, and the handle is provided with a second rotating positioning member; in the use state, the first rotating positioning member and the second rotating positioning member are in a concave-convex fit to limit circumferential rotation.

[0015] The present invention is further configured such that: a third rotation positioning member is provided on the connector; in the first folded state, the third rotation positioning member and the second rotation positioning member are in concave-convex fit to limit circumferential rotation; the third rotation positioning member is provided with a sliding opening, which is used to allow the second rotation positioning member to slide out of the third rotation positioning member during the process of switching from the first folded state to the second folded state.

[0016] A handheld unit, characterized in that it comprises: a mounting frame having a mounting position for mounting a lint roller, and a connecting rail extending along the length of the mounting frame; a handle having a connector at one end; the connector and the connecting rail being aligned and assembled such that the mounting frame and the handle are in a rotational configuration about the connector as a rotation center and a sliding configuration about the connecting rail as a sliding track; the handle sliding relative to the mounting frame to bring the connector closer to the middle of the length of the mounting frame and the handle flipping relative to the mounting frame to move the middle of the length of the handle away from the mounting frame to form a use state; the handle sliding relative to the mounting frame to move the connector away from the middle of the length of the mounting frame and the handle flipping relative to the mounting frame to bring the middle of the length of the handle closer to the mounting frame to form a second folded state.

At this time, the lint roller is T-shaped, making it easier to hold the handle, and the lint roller is rotated by pushing it forward to remove lint. 2. When the lint roller is not needed, the handle in the usage state can be flipped relative to the mounting bracket to move the middle of the handle closer to the mounting bracket to form a first folded state. In this state, although the handle will still partially extend to the left... The mounting bracket, compared to the T-shaped handheld unit in use, provides the first fold, making it even more compact. This facilitates storage, improves transportation efficiency, and reduces packaging costs. 3. When the lint roller is not needed, the handle can be slid to the right from the first folded state to form a second folded state. In this state, the space on the right side of the connector allows the part of the handle that extends to the left to retract, achieving a perfect overlap between the mounting bracket and the handle in the left and right directions. This results in optimal compactness, optimized storage, maximum transportation efficiency, and minimum packaging costs. Attached Figure Description

[0045] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0046] Example 1:

[0047] like Figures 1-8 As shown, this utility model discloses a handheld unit, comprising:

[0048] Mounting frame 1 is U-shaped with the opening facing forward and its length is along the left and right direction. Mounting position 11 for mounting the lint roller 3 is provided in the U-shaped area of ​​mounting frame 1, and connector 12 is provided in the middle of the rear side of mounting frame 1.

[0049] Handle 2 is long and narrow, and one end of handle 2 is provided with a connecting rail 21 extending to the other end;

[0050] The connector 12 and the connecting rail 21 are aligned and assembled so that the mounting bracket 1 and the handle 2 are in a rotating configuration with the connector 12 as the rotation center and a sliding configuration with the connecting rail 21 as the sliding rail.

[0051] Among them, the handle 2 has relative to the mounting bracket 1 Figure 1 The usage status shown Figure 3 The first folding state shown and Figure 4 The second folded state is shown. Specifically:

[0052] In use, the length of the handle 2 is along the front-to-back direction, and the connector 12 is fitted to the front end of the connecting rail 21 so that the handheld unit is in a T-shape. This is the use state of most lint rollers. The specific usage method will not be described in detail.

[0053] In the first folded state, the length direction of the handle 2 is parallel to the length direction of the mounting bracket 1 along the left-right direction, and the connector 12 is engaged with the right end of the connecting rail 21, so that the handheld unit is in a straight line shape. However, because the handle 2 is relatively long, the left end of the handle 2 extends to the left end of the mounting bracket 1, and at this time, the left-right length of the handheld unit reaches its maximum. The first folded state is obtained by flipping the handheld unit relative to the mounting bracket 1 with the handle 2 as the rotation center around the connector 12 in the use state. Conversely, flipping the handle 2 around the connector 12 changes the handheld unit from the first folded state to the use state.

[0054] In the second folded state, the length direction of the handle 2 is parallel to the length direction of the mounting bracket 1 along the left and right directions, and the connector 12 is fitted to the left end of the connecting rail 21, so that the handheld unit is in a straight line shape. In addition, the left and right coverage areas of the handle 2 and the left and right coverage areas of the mounting bracket 1 have a high degree of overlap, and the left and right length of the handheld unit is minimized. The second folded state is obtained by sliding the handheld unit in the first folded state to the right, so that the connector 12 gradually moves closer to the middle of the handle 2, and the length of the handle 2 is more evenly distributed at both ends of the connector 12. Conversely, the second folded state is transformed into the first folded state.

[0055] Therefore, 1. When the lint roller needs to be used, the handle 2 is slid relative to the mounting bracket 1 so that the middle of the length of the handle 2 is away from the connector 12, and the handle 2 is flipped relative to the mounting bracket 1 so that the middle of the length of the handle 2 is away from the mounting bracket 1 to form a working state. At this time, the lint roller is T-shaped, making it easier to hold the handle 2, and the lint roller 3 is rotated by pushing it forward to remove lint. 2. When the lint roller is not needed, the handle 2 in the working state is flipped relative to the mounting bracket 1 so that the middle of the length of the handle 2 is close to the mounting bracket 1 to form a first folded state. In this state, although the handle 2 still extends partly to the left of the mounting bracket 1, compared with the T-shaped handheld state in the working state, the lint roller is more convenient to hold. The first fold of the lint roller makes it even more compact, which facilitates storage, improves transportation efficiency, and reduces packaging costs. In addition, since the handle 2 extends out of the mounting bracket 1, the extended handle 2 can also be used in a straight position for lint removal. When the lint roller is not needed, the handle 2 can be slid to the right from the first folded state to form a second folded state. In this state, the space on the right side of the connector 12 is used to retract the leftward extension of the handle 2, so that the mounting bracket 1 and the handle 2 are highly aligned in the left and right directions to achieve the optimal compact state, thereby optimizing storage, maximizing transportation efficiency, and minimizing packaging costs.

[0056] Specifically, in this embodiment, the connecting track 21 is provided with an unfolding position 211 and a storage position 212; wherein, in the use state and the first folded state, the connector 12 is located in the unfolding position 211; in the second folded state, the connector 12 is located in the storage position 212. Preferably, both the unfolding position 211 and the storage position 212 are located at the ends of the connecting track 21, so that the connector 12 can be quickly positioned by sliding to the unfolding position 211 and the storage position 212 by abutting against the ends of the connecting track 21.

[0057] The unfolded position 211 is located at the end of the handle 2, so that the connector 12 slides toward the unfolded position 211 and approaches the end of the handle 2, so that the handle 2 is extended to its longest position in the use state and the first folded state, making it easy to hold.

[0058] The storage position 212 is located in the middle of the length of the handle 2, so that the connector 12 slides toward the storage position 212 and approaches the middle of the handle 2. In the second folded state, the connector 12 is located in the middle of the handle 2 so that the length of the handle 2 is evenly distributed on both sides, thus making the folding effect better.

[0059] Wherein, the length of the mounting bracket 1 is s1, and the length of the handle 2 is s2, wherein s1 / 2≤s2, so that in this setting, the handle 2 portion in the first folded state extends to the left of the mounting bracket 1.

[0060] More preferably, s1 / 2≤s2≤s1, so that in the second folded state, the mounting bracket 1 covers the left and right ends of the handle 2 to prevent the handle 2 from extending to the left and / or right and sliding under force.

[0061] Preferably, the handle 2 in this embodiment is provided with a sliding positioning member 22. The sliding positioning member 22 is used to restrict the connector 12 from sliding away from the middle of the length of the handle 2 in the second folded state, so that the handle 2 is more stable in the second folded state.

[0062] Specifically, the sliding positioning member 22 is located inside the connecting track 21 and is protruding so that the connecting member 12 passes over the sliding positioning member 22 for positioning.

[0063] Furthermore, in this embodiment, the mounting bracket 1 is provided with a positioning plane 13 at the connector 12, and the long end of the handle 2 is provided with a positioning arc surface 23. During the process of the handle 2 flipping from the use state to the first folded state, the positioning plane 13 and the positioning arc surface 23 are always tangent and / or abutting each other, so that when the handle 2 is flipped forward in the use state, the abutting of the positioning plane 13 and the positioning arc surface 23 will restrict the relative sliding of the handle 2 and the mounting bracket 1, making the use smoother. Moreover, when the handle 2 is flipped from the use state to the first folded state, the positioning plane 13 and the positioning arc surface 23 remain tangent, and the appropriate deflection of the handle 2 can ensure stable positioning and smooth sliding, making the compatibility higher.

[0064] In addition, the connector 12 in this embodiment is provided with a first rotation positioning member 14, specifically a hemispherical groove, and the handle 2 is provided with a second rotation positioning member 24, specifically a moving member that slides vertically by a spring. The lower end of the moving member is hemispherical, so that in the use state, the first rotation positioning member 14 and the second rotation positioning member 24 are in concave-convex fit to perform circumferential rotation limit, so as to further improve the stability of use.

[0065] In addition, the connector 12 in this embodiment is provided with a third rotation positioning member 15, which is a straight groove, and the straight end extends towards the connector 12. In the first folded state, the third rotation positioning member 15 and the second rotation positioning member 24 are in concave-convex cooperation to perform circumferential rotation limit.

[0066] The second rotating positioning member 24 can cooperate with the first rotating positioning member 14 and the third rotating positioning member 15, making it easier to find the usage state and the first folded state.

[0067] Preferably, the end of the straight extension of the third rotation positioning member 15 away from the connector 12 is provided with a sliding opening 151. The sliding opening 151 is used to allow the second rotation positioning member 24 to slide out of the third rotation positioning member 15 during the process of switching from the first folded state to the second folded state, making the operation smoother.

[0068] The connector 12 is rotatably mounted on the mounting bracket 1. At this time, the connector 12 may or may not rotate relative to the connecting track 21.

[0069] In addition, the connector 12 can be fixed or integrally installed on the mounting bracket 1, but the connector 12 and the connecting rail 21 need to rotate relative to each other.

[0070] Example 2:

[0071] like Figure 9 As shown, a handheld unit has the same main structure as Embodiment 1, except that the two ends of the connecting rail 21 are located at the two ends of the length of the handle 2, the number of unfolding positions 211 is two, the number of storage positions 212 is one, the two unfolding positions 211 are located at the two ends of the connecting rail 21, and the storage position 212 is located in the middle of the connecting rail 21 between the two unfolding positions 211.

[0072] This allows both ends of the handle 2 to be adjusted for use.

[0073] Example 3:

[0074] like Figures 10-12 As shown, this utility model discloses a handheld unit, comprising:

[0075] Mounting frame 1 is U-shaped with the opening facing forward and its length is along the left and right direction. Mounting position 11 for mounting the lint roller 3 is provided in the U-shaped area of ​​mounting frame 1. A connecting rail 21 extending left and right is provided on the rear side of mounting frame 1, with one end of the connecting rail 21 located at the left end of mounting frame 1 and the other end located at the middle of mounting frame 1.

[0076] Handle 2, which is long and narrow, and has a connector 12 at one end;

[0077] The connector 12 and the connecting rail 21 are aligned and assembled so that the mounting bracket 1 and the handle 2 are in a rotating configuration with the connector 12 as the rotation center and a sliding configuration with the connecting rail 21 as the sliding rail.

[0078] Among them, the handle 2 has relative to the mounting bracket 1 Figure 10 The usage status shown Figure 11 The first folding state shown and Figure 12 The second folded state is shown. Specifically:

[0079] In use, the length of the handle 2 is along the front-to-back direction, and the connector 12 is fitted to the rightmost end of the connecting rail 21 so that the handheld unit is in a T-shape. This is the use state of most lint rollers. The specific usage method will not be described in detail.

[0080] In the first folded state, the length direction of the handle 2 is parallel to the length direction of the mounting bracket 1 along the left-right direction, and the connector 12 is engaged with the right end of the connecting rail 21, so that the handheld unit is in a straight line shape. However, because the handle 2 is relatively long, the right end of the handle 2 extends to the right end of the mounting bracket 1, and at this time, the left-right length of the handheld unit reaches its maximum. The first folded state is obtained by flipping the handheld unit relative to the mounting bracket 1 with the handle 2 as the rotation center around the connector 12 in the use state. Conversely, flipping the handle 2 back to the use state changes it from the first folded state.

[0081] In the second folded state, the length direction of the handle 2 is parallel to the length direction of the mounting bracket 1 along the left and right directions, and the connector 12 is fitted to the left end of the connecting rail 21, so that the handheld unit is in a straight line shape. In addition, the left and right coverage areas of the handle 2 and the left and right coverage areas of the mounting bracket 1 have a high degree of overlap, and the left and right lengths of the handheld unit are minimized. The second folded state is obtained by sliding the handheld unit in the first folded state to the left, so that the connector 12 gradually moves closer to the left side of the mounting bracket 1, and the rightward extension of the handle 2 gradually aligns with the mounting bracket 1. Conversely, the second folded state is transformed into the first folded state.

[0082] Therefore, 1. When the lint roller needs to be used, the handle 2 is slid relative to the mounting bracket 1 so that the connector 12 is close to the middle of the length of the mounting bracket 1, and the handle 2 is flipped relative to the mounting bracket 1 so that the middle of the length of the handle 2 is away from the mounting bracket 1 to form the use state. At this time, the lint roller is T-shaped, making it easier to hold the handle 2, and the lint roller 3 is rotated by pushing it forward to remove lint. 2. When the lint roller is not needed, the handle 2 in the use state can be flipped relative to the mounting bracket 1 so that the middle of the length of the handle 2 is close to the mounting bracket 1 to form a first folded state. In this state, although the handle 2 still extends partly to the right of the mounting bracket 1, compared with the T-shaped handheld state in the use state, it is more convenient to hold the handle 2. The unit acts as the first fold, making it even more compact, which facilitates storage, improves transportation efficiency, and reduces packaging costs. In addition, since the handle 2 extends out of the mounting bracket 1, the extended handle 2 can also be used to hold the lint roller in a straight position. 3. When the lint roller is not needed, the handle 2 can be slid to the left from the first folded state to form a second folded state. In this state, the space on the left side of the mounting bracket 1 is used to retract the leftward extension of the handle 2, so that the mounting bracket 1 and the handle 2 are highly aligned in the left and right directions to achieve the optimal compact state, thereby optimizing storage, maximizing transportation efficiency, and minimizing packaging costs.

[0083] Example 4:

[0084] like Figures 13-15 As shown, a lint roller includes a handheld unit as described in any one of embodiments one to three, a lint roller 3, and a protective cover 4. The lint roller 3 has round holes 31 at both ends, and the inner sides of the U-shaped ends of the mounting frame 1 have cylinders 111, so that the lint roller 3 can be rotated and installed in the mounting position 11 by the engagement of the cylinders 111 and the round holes 31. The protective cover 4 is detachably fitted to the mounting frame 1 by a snap-fit ​​positioning method, so that the protective cover 4 can be removed for use when the lint roller 3 is needed, and can be put on for protection when the lint roller 3 is not needed.

[0085] Among them, the state of handle 2 can be switched to Figure 13 Use it in the state shown, and switch to Figure 14 Fold and store as shown.

[0086] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
