Description

Technical Field

[0001] This patent relates to the field of pen grip technology, and in particular to a pen grip and pen tool suitable for pens of different diameters. Background Technology

[0002] Currently, most pencils on the market are made of wood, and they come in various diameters and types. Wooden pencils are essential for children's handwriting practice and homework before and after school. However, because the surface of the pencil is relatively hard, children's hands are delicate, and holding a pencil for a long time can easily cause fatigue, calluses, and finger deformities, affecting their interest in using pencils. Usually, a soft rubber pencil grip is needed to use the pencil. Focusing on students of other age groups, although they do not use wooden pencils often, ballpoint pens or gel pens are their most frequently used stationery. When academic pressure is too great or there is a lot of homework, students will rapidly increase their writing speed, neglecting the importance of proper pen grip. This leads to many students developing calluses of varying sizes on their knuckles, which can cause irreversible finger deformities over time. Therefore, a pencil grip is needed to use the pencil.

[0003] A pen grip is a writing aid designed to improve writing posture. It guides users to hold the pen correctly, reducing hand tension and pressure while writing. These pen grips are designed according to ergonomic principles to adapt to the natural shape and movement of the hand. Posture-correcting pen grips are typically easy to install and remove, suitable for users of different ages and hand shapes. For children, they help cultivate good writing habits and prevent writing difficulties caused by poor pen grip posture.

[0004] Currently, pen grips on the market are often designed with attractive appearances to appeal to children's learning, such as animal shapes or cartoon characters. Some pen grips also aim to improve comfort and functionality during writing, for example, by increasing the softness of the grip material to reduce discomfort, prevent repetitive strain injuries, and improve writing accuracy and speed. Others increase the friction between the grip and the fingers, using its elasticity to increase friction with the pencil barrel. However, once the pen grip is used frequently and exceeds the lifespan of the elastic material, or if the elastic material ages due to environmental pollutants, it can easily slip when placed on the outside of the pen, rendering the grip unusable. Existing pen grips typically involve inserting the pen into a through-hole and using a structure to secure the pen and prevent relative slippage, allowing for a better grip. However, this design makes it more difficult for users to control the pressure applied to the grip.

[0005] However, the compatibility of pen grips with different diameters is often overlooked. Currently, the soft rubber pen grips on the market are relatively limited, with each grip only compatible with one pen diameter. Given the wide variety of pen sizes available, consumers need to purchase grips of various sizes, increasing usage costs and making storage more difficult. To improve the user experience, based on the principles of mechanical interaction during gripping, a soft rubber pen grip that can accommodate more pen sizes needs to be developed, facilitating consumer use and enhancing comfort. Utility Model Content

[0006] To enable the pen grip to be compatible with pens of various diameters and to improve its stability and user comfort, this patent provides the following technical solutions:

[0007] First aspect: A pen grip suitable for pens of different diameters is provided. The pen grip includes a tubular soft sleeve that encloses a receiving cavity for accommodating the pen barrel. A support portion is provided in the receiving cavity and along the inner wall of the soft sleeve. The pen barrel is held relatively fixed by the support portion after passing through the receiving cavity. When the support portion is in a completely natural state, the diameter of the pen barrel is the minimum diameter allowed to pass through the support portion. When the support portion is in a fully compressed state, the diameter of the pen barrel is the maximum diameter allowed to pass through the receiving cavity.

[0008] Furthermore, the support includes multiple support ribs, with the number of support ribs being 8-11, 11-14, or 14-17.

[0009] Furthermore, the support portion includes a rib extrusion cavity for accommodating the extruded support ribs; the portion of the support ribs that contacts the pen barrel is a clamping cavity with a diameter of 6.8-8.0 mm, 8.0-9.2 mm, or 9.2-10.4 mm.

[0010] Furthermore, the supporting ribs include a head, a middle section, a tail, and a stop bar. The stop bar is located on the side wall of the middle section and is used to provide friction for the pencil barrel to maintain relative fixation.

[0011] Furthermore, the head and tail have tilt angles of 63-68°, 68-73°, or 73-78°.

[0012] Furthermore, the soft sleeve includes an inlet at the front end and an outlet at the end, and the outer wall of the soft sleeve is provided with a gripping part, which includes a thumb pressing part, an index finger pressing part and a middle finger pressing part.

[0013] Furthermore, the diameter of the receiving cavity is selected from 10.4-11.0 mm, 11.0-11.6 mm, or 11.6-12.2 mm.

[0014] Furthermore, the soft sleeve and the support are integrally molded using the same material, which is an elastic and soft material selected from rubber, elastomeric plastics, polyurethane foam, elastic fibers, and silicone.

[0015] The second aspect: provides a pen tool suitable for the above-mentioned pen grip, the pen tool including a pen tip and a pen barrel; the minimum diameter D1 of the pen barrel is selected from 6.8mm, 6.9mm or 7.0mm; the maximum diameter D2 of the pen barrel is selected from 9.8-10.0mm, 10.0-10.2mm or 10.2-10.4mm.

[0016] Furthermore, the cross-sectional shape of the pen barrel is selected from one of a circle, a triangle, and a hexagon.

[0017] This patent has the following beneficial effects:

[0018] 1. This patent relates to the field of pen sleeve technology, a pen grip suitable for pens of different diameters, including a soft sleeve body, a support part and a receiving cavity. The soft sleeve body and the support part are integrally molded using an elastic and soft material. Through the structure and material properties of the support part, the pen grip is suitable for pens of different diameters, avoiding the situation where the pen grip is relatively simple and a single pen grip can only be used with a pen of one diameter.

[0019] 2. The support part in this patent includes a support rib and a rib compression cavity. The expansion and fixation of the pen barrel after entering the receiving cavity are achieved by the cooperation between the support rib and the rib compression cavity and the structure of the support rib. The maximum diameter D2 and the minimum diameter D1 suitable for the pen grip are determined by the degree of compression of the support rib.

[0020] 3. In this patent, when the support part is in a completely natural state, the diameter of the pen barrel is the minimum diameter allowed to pass through the support part; when the support part is in a fully compressed state, the diameter of the pen barrel is the maximum diameter allowed to pass through the receiving cavity.

[0021] 4. The elastic and soft material used in this patent has both good elasticity and a certain degree of rigidity. Good elasticity is to provide users with a comfortable feel and support the elastic deformation of the pen grip during use. A certain degree of rigidity is to allow the supporting ribs to flip into the rib compression cavity under full compression without breaking.

[0022] 5. The supporting ribs in this patent include a head, a tail, a middle section and a stop bar. The head and tail are inclined at an angle along the axial direction. This is to provide a smooth transition when the pen barrel enters the receiving cavity and enters the support part.

[0023] 6. In this patent, the outer wall of the soft sleeve is provided with corresponding thumb squeezing part, index finger squeezing part and middle finger squeezing part according to the gripping effect, and an anti-slip structure is provided to further improve the use effect of the pen grip.

[0045] The detailed features and advantages of this patent are described below in the specific embodiments. The content is sufficient to enable any person skilled in the art to understand the technical content of this patent and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, a person skilled in the art can easily understand the related objectives and advantages of this patent.

[0046] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0047] The pen grip provided in this application is compatible with pen barrels of different diameters, but it does not impose many limitations on the types of pens. It is easy to understand that the pen grip provided in this application can be used with ballpoint pens, pencils, mechanical pencils, markers, highlighters, whiteboard markers, crayons, fountain pens, and erasable pens. In this embodiment, the pen used is a pencil, which includes the pencil tip and the pencil barrel. In the following embodiment, the specific pencil will be used to refer to the pens that are generally applicable.

[0048] Please refer to Figures 1-3 A pen grip suitable for pens of different diameters includes a soft sleeve 100, which forms a long tubular structure that runs through the front and back. The end of the soft sleeve 100 is an inlet 110 and the rear end is an outlet 120. The cavity inside the soft sleeve 100 is a receiving cavity 300 for accommodating the pencil barrel. The outer wall of the soft sleeve 100 is provided with a soft-touch, non-slip gripping part 130, which includes a thumb pressing part 131, an index finger pressing part 132 and a middle finger pressing part 133.

[0049] Specifically, the thumb pressing part 131 and the index finger pressing part 132 are arranged adjacent to each other, and the middle finger pressing part 133 is located at the bottom of the outer wall of the pen holder, which conforms to the standard pen holding posture. The thumb pressing part 131, the index finger pressing part 132 and the middle finger pressing part 133 are designed according to the size of children's fingers, and their shape is a concave arc surface.

[0050] Specifically, the curved surfaces of the thumb pressing part 131, index finger pressing part 132, and middle finger pressing part 133 that contact the fingertips are provided with curved baffles to increase the friction between the contact surfaces and the fingertips, making it less likely for children to slip the pen holder during gripping; the curved baffles are set at the front of the thumb pressing part 131, index finger pressing part 132, and middle finger pressing part 133 according to the fingerprint shape, with three baffles set on each curved surface.

[0051] A pen grip suitable for pens of different diameters also includes a support 200, which is disposed in a receiving cavity 300. Specifically, the support 200 is disposed circumferentially on the inner wall of the soft sleeve 100. The pencil barrel passes through the inlet 110 into the receiving cavity 300, then passes through the support 200, exits from the support 200, enters the receiving cavity 300, and finally exits from the outlet 120.

[0052] The support part 200 includes a varying number of support ribs 210. In this embodiment, there are 10 support ribs 210. A rib compression cavity 220 is provided between adjacent support ribs 210. The rib compression cavity 220 is used to accommodate the compressed support ribs 210.

[0053] Specifically, the part of the supporting rib 210 that contacts the pen barrel is the clamping cavity 400. The clamping cavity 400 is smaller than the receiving cavity 300, and the clamping cavity 400 varies according to the diameter of the pen barrel. When the pen barrel is at its minimum diameter D1, the supporting rib 210 just contacts the pen barrel without deformation, and the diameter of the clamping cavity 400 is equal to the minimum diameter D1 of the pen barrel. When the pen barrel is at its maximum diameter D2, the supporting rib 210 deforms and flips due to the excessively large pen barrel diameter, and is squeezed into the rib compression cavity 220. At this time, the diameter of the clamping cavity 400 is equal to the maximum diameter D2 of the pen barrel.

[0054] Specifically, the diameter of the clamping cavity varies in the range of 6.8-8.0mm, 8.0-9.2mm, or 9.2-10.4mm.

[0055] After the pencil barrel enters the support part 200, there are two states. If the diameter of the pencil barrel is exactly equal to the diameter formed by the support part 200, then the pencil barrel is just fixed by the support rib 210 without compressing the support rib 210. At this time, the support part 200 is in a completely natural state.

[0056] If the diameter of the pencil barrel is greater than the diameter formed by the support part 200, but the diameter of the pencil barrel is less than the maximum diameter that the receiving cavity 300 can accommodate, then no matter what angle the pencil barrel enters the support part 200 from, it will cause the support rib 210 to flip, and the flipped support rib 210 will enter the rib compression cavity 220.

[0057] If the diameter of the pencil barrel is exactly the maximum diameter that the receiving cavity 300 can accommodate when it enters the support part 200, the support rib 210 will be squeezed to the maximum extent into the rib compression cavity 220, and the support part 200 will be in a fully compressed state.

[0058] The support rib 210 includes a head 211, a middle section 212, a tail 213, and a stop bar 214. The cross-sectional shape of the support rib 210 in the radial direction is triangular. The tops of the head 211 and the tail 213 of the support rib 210 are inclined at an angle in the axial direction. The design of the inclined angle allows the pencil barrel to smoothly transition from the receiving cavity 300 into and out of the support part 200 without getting stuck.

[0059] Specifically, the tilt angle of the head and tail is 70°.

[0060] Specifically, the middle section 212 is located between the head 211 and the tail 213, and is distributed along the axial direction on the inner wall of the soft sleeve 100. The top of the middle section 212 is a stop bar 214. The stop bar 214 can generate friction with the contacting pencil barrel, which is convenient for fixing pencil barrels with small diameters. When the diameter of the pencil barrel is too large, the different contact surfaces of the support rib 210 as a whole interact with the pencil barrel to generate friction, thereby fixing the pencil barrel.

[0061] Specifically, the diameter of the cavity 300 is 10.7 mm.

[0062] Specifically, the soft sleeve 100 and the support part 200 are integrally molded using the same material, which is an elastic and soft material. This elastic and soft material is able to accommodate pencil barrels of different diameters while also having a certain rigidity so that the support ribs 210, which are fully rotated when the pen grip is in a fully compressed state, will not break.

[0063] Specifically, the elastic and soft material is selected from one of rubber, elastomeric plastics, polyurethane foam, elastic fibers, and silicone, but this patent is not limited to this.

[0064] Specifically, rubber can include natural rubber (NR), styrene-butadiene rubber (SBR), silicone rubber (VMQ), and chloroprene rubber (CR).

[0065] Specifically, elastomeric plastics can include thermoplastic polyurethane (TPU), styrene-based elastomers (SEBS), thermoplastic polyester elastomers (TPEE), and polyolefin elastomers (POE).

[0066] Specifically, polyurethane foam can include open-cell flexible PU foam and highly elastic microporous PU foam.

[0067] Specifically, elastic fiber composites can include spandex and latex filaments.

[0068] Specifically, silicone can include fumed silica (LSR), nano-modified silica, and medical-grade platinum-cured silica.

[0069] Specifically, a pencil includes a pencil tip and a pencil shaft, and the pencil is suitable for the pencil grip in this embodiment. After the pencil is inserted into the pencil grip, when the pencil grip is in a completely natural state, the pencil shaft at this time is the pencil shaft with the smallest diameter suitable for the pencil grip, and the minimum diameter D1 at this time is 7.0 mm.

[0070] Specifically, when the pen grip is in a fully compressed state, the support rib 210 is completely flipped into the rib compression chamber 220, the support rib 210 undergoes maximum deformation, and the pencil barrel is the pencil barrel with the largest diameter suitable for the pen grip, at which time the maximum diameter D2 is 10.2mm.

[0071] This patent specification uses directional terms such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom" to describe various example structural parts and components of this patent. However, the use of these terms is merely for illustrative purposes and is based on the orientation of the examples shown in the accompanying drawings. Since the embodiments disclosed in this patent can be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or the same as the direction of gravity.

[0072] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this patent will not describe the various possible combinations separately.

[0073] Furthermore, various implementations of this patent can be combined in any way, as long as they do not violate the spirit of this patent, they should also be regarded as the content disclosed in this patent.
