Description

Technical Field

[0001] The utility model relates to the field of components for hand gripping, in particular to a grip and a gripping handle. Background Art

[0002] Components for hand gripping usually include a rigid member inside and a grip sleeved outside the rigid member. The rigid member is integrated with the operating mechanism of a device to be controlled (such as a bicycle, an automobile, a manual tool, etc.) (the handlebar of a bicycle, the steering mechanism of an automobile, the body of a manual tool), and the grip serves as a medium between the hand and the rigid member to provide functions such as increasing friction and buffering vibration.

[0003] Some gripping handles are made into a hollow structure to achieve air convection to ensure the dryness of the hand. For example, the breathable and anti-slip grip sleeve for a bicycle handlebar disclosed in CN107380333A uses pure titanium to make a sleeve body with a breathable network tube structure and combines it with a breathable gap layer to attempt to solve the ventilation inside the handlebar, facilitate sweating, and improve riding safety. However, from its structure, it can be seen that cavities separated from each other are formed between the lead screws, and the air flow can only flow inside each cavity and cannot flow between the cavities. Especially in the gripping state, most of the cavities are pressed by the hand (or glove) and completely blocked, and the air flow is blocked. Only some of the cavities at the edge of the hand that are partially blocked can have air flow, and the air flow can hardly reach other positions except the edge of the hand. Even if it can reach the edge, the fluidity is further limited because the air flow can only flow inside and outside, so the actual improvement in ventilation is very limited.

[0004] Therefore, to solve the above problems, the embodiments of the utility model provide a grip and a gripping handle. Summary of the Utility Model

[0005] The embodiments of the utility model provide a grip and a gripping handle, which at least solve the following problems: the ventilation effect is limited and is not sufficient to dry the sweat on the hand in time.

[0006] The first aspect of the embodiments of the utility model provides a grip, which includes:

[0007] A gripping surface for a user's hand to grip;

[0008] An installation surface configured such that at least a part of it is locked on the outer surface of a rigid member, and the installation surface extends along a longitudinal axis to form an installation chamber for accommodating the rigid member;

[0009] A thickness part defined by the area between the gripping surface and the installation surface, and the thickness part is configured with a plurality of radially communicating ventilation holes and axially communicating ventilation holes. The radially communicating ventilation holes extend in a direction close to / away from the longitudinal axis, and the axially communicating ventilation holes extend along the longitudinal axis.

[0010] By installing the rigid part into the installation chamber, at least a part of the installation surface is locked to the outer surface of the rigid part. The user's hand can operate the rigid part by holding the gripping surface, thereby driving various operating mechanisms connected to the rigid part (such as the handlebars of the bicycle, the steering wheel of the car, and the body of the hand tool described in the background technology). The rigid part provides sufficient support for the user's hands from the inside out. During the operation process, the user's hands may sweat (especially the grip of the gripping surface by the palm of the hand). Multiple ventilation channels are formed by interconnected radial ventilation holes and axial ventilation holes to ensure that every part of the user's hand (except the part forming the ventilation channel) can be effectively ventilated, thereby inhibiting the formation of sweat, avoiding slipping caused by sweat and affecting the operation, ensuring the dryness of the user's hands, and ensuring operability.

[0011] The inventor found that the handle cover is installed on the rigid part, in part, by its own elasticity, and is tightly wrapped around the rigid part. For this installation method, the elasticity of the handle cover along its own extension direction is fixed, resulting in the installation resistance increasing continuously as the installation length increases when the handle cover is installed on the rigid part, causing installation difficulties. Based on this concept, the inventor further made a locking force F between the end of the installation surface and the outer surface of the rigid part in the locked state. 锁紧-端部 > The locking force F between the middle part of the mounting surface and the rigid outer surface 锁紧-中间部 That is, when installing the grip, only one or two ends of the F 锁紧-端部 In the middle part, only an F smaller than that is required. 锁紧-中间部 In extreme cases, F 锁紧-中间部 can be as small as 0, thereby greatly reducing the resistance during installation; and, in the state of use, due to the gripping and pressing of the hands, the middle part of the installation surface and the rigid part generate a certain friction force, and the existence of this friction force further makes F 锁紧-端部 >F 锁紧-中间部 settings become possible.

[0012] In addition, the thickness portion is made of elastic material. This ensures the buffering and shock absorption effects. It ensures the comfort of use. At the same time, due to the force applied by the user, the thickness portion at the location with large force is locally deformed to form a depression, which plays a positioning role for the hand, prevents the hand from falling off, and increases the controllability. In particular, only the above-mentioned radial ventilation holes and axial ventilation holes are used, and through the selection of material elasticity, the radial ventilation holes and the axial ventilation holes can still be connected to each other even after deformation, and the ventilation effect is continuously guaranteed.

[0013] Further, the thickness portion has a proximal end and a distal end with different distances from the mounting surface, and the elastic modulus of the proximal end > the elastic modulus of the distal end. In this way, when the force is constant, the amount of deformation occurring at the proximal end < the amount of deformation occurring at the distal end, thereby providing the maximum shock absorption effect at the distal end (the outermost distal end is the gripping surface in contact with the hand), and providing maneuverability at the proximal end (the smaller the delay in the movement of the proximal end being transmitted to the rigid member, the better the maneuverability).

[0014] In order to further increase the ventilation effect and shock absorption effect, the thickness portion is a multi-layer structure. At this time, the axial ventilation holes can be arranged in multiple numbers in the radial direction to weaken the problem of the reduction of the axial ventilation holes due to the compression of the hand.

[0015] Due to ventilation requirements, it is required that the radial ventilation holes and the axial ventilation holes communicate with each other. The cavity structures are small and numerous, and it is difficult to achieve by traditional processing methods such as injection molding; due to installation convenience, it is also required that F 锁紧-端部 >F 锁紧-中间部 , that is, different elastic force magnitudes are required, and it cannot be achieved by traditional processing methods. Considering this, the handle cover is made by 3D printing with 3D printing materials. The corresponding 3D printing materials can be selected from the elastomers with a hollow structure disclosed in CN218971713U, CN219182950U, CN111438932A, CN212737077U, and CN111418956B, and printed using the DLP printing process.

[0016] Further, at least one end of the thickness portion is formed with an annular first locking portion, F 锁紧-端部 >F 锁紧-中间部 which is achieved by at least one of the following:

[0017] The elastic modulus of the first locking portion > the elastic modulus of the middle portion;

[0018] When the handle cover and the rigid member are in an unassembled state, the distance from the first locking portion to the center > the distance from the middle portion to the center.

[0019] Further, an annular second locking portion is constructed in the middle portion of the mounting surface. Corresponding to the case where F 锁紧-中间部 ≠0.

[0020] Further, no annular locking portion is constructed in the middle portion of the mounting surface. Corresponding to the case where F 锁紧-中间部 =0.

[0021] The second aspect of the embodiments of the present invention provides a gripping handle, which includes any one of the above:

[0022] Handle cover; and

[0023] Rigid member.

[0024] The holding handle can be applied to bicycles, motorcycles, automobiles, etc., as long as they are equipped with rigid members in the shape of rods (including the handlebars of bicycles extending in a straight line, and also including the steering wheels of automobiles extending in an arc or even a circle).

[0025] The beneficial effects of the embodiments of the present utility model at least include:

[0026] By installing the rigid member into the installation chamber, at least a part of the installation surface is locked on the outer surface of the rigid member. The user's hand can operate the rigid member by holding the holding surface, thereby driving each operating mechanism connected to the rigid member (such as the handlebars of a bicycle, the steering wheel of an automobile, and the body of a hand tool as described in the background art). The rigid member provides sufficient support for the user's hand from the inside out. During the operation process, the user's hand may sweat (especially when the palm part holds the holding surface). Through the radially communicating ventilation holes and axially communicating ventilation holes, a plurality of ventilation channels are formed to ensure that every part of the user's hand (except the part where the ventilation channels are formed) can be effectively ventilated, thereby suppressing the formation of sweat, avoiding slippage caused by sweat and affecting the operation, ensuring the dryness of the user's hand, and ensuring the operability.

[0042] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] The first aspect of the embodiment of the present utility model discloses a grip sleeve, see Figures 1 to 8 , which includes a grip surface 11, a mounting surface 12 and a thickness part 13.

[0046] The gripping surface 11 is for the user's hand to grip, so the gripping surface 11 should have a smooth transition, such as the cylindrical shape shown in the figure (ignoring the depression at the radial ventilation hole 131). Of course, it can also be made to conform to ergonomics, with a part in contact with the palm of the hand, depressions for accommodating fingers, etc.

[0047] The mounting surface 12 is configured such that at least a part of it is locked to the outer surface of a rigid member (not shown in the figure). In the figure, it is shown that the whole is locked to the outer surface of the rigid member. The mounting surface 12 extends along the longitudinal axis to form a mounting chamber 14 for accommodating the rigid member. During installation, the rigid member can be inserted into the mounting chamber 14. Therefore, the mounting chamber 14 has a shape adapted to the outer contour of the rigid member. As shown in the figure, when the outer contour of the rigid member is cylindrical, the mounting chamber 14 is an inner cylindrical shape.

[0048] The thickness portion 13 is defined by the region between the gripping surface 11 and the mounting surface 12. The thickness portion 13 is configured with a plurality of radially communicating ventilation holes 131 and axially communicating ventilation holes 132. The radially extending ventilation holes 131 extend in a direction close to / away from the longitudinal axis, and the axially extending ventilation holes 132 extend along the longitudinal axis. The size of the thickness portion 13 should be sufficient to accommodate the axially extending ventilation holes 132 to ensure the ventilation effect, such as 1 - 10 cm. The shape of the radially extending ventilation holes 131 can be quadrilateral, triangular, polygonal, circular, or even an irregular shape. Adjacent radially extending ventilation holes 131 and axially extending ventilation holes 132 can all communicate.

[0049] In addition, in the locked state, the locking force F between the end of the mounting surface 12 and the outer surface of the rigid member 锁紧-端部 > the locking force F between the middle part of the mounting surface 12 and the outer surface of the rigid member 锁紧-中间部 .

[0050] In addition, the thickness portion 13 is made of an elastic material, such as rubber, photocurable resin, etc.

[0051] It should also be noted that the thickness portion 13 has a proximal end (the end with a relatively closer distance to the central axis of the mounting chamber 14) and a distal end (the end with a relatively farther distance to the central axis of the mounting chamber 14) with different distances to the mounting surface 12. The elastic modulus of the proximal end > the elastic modulus of the distal end. Thus, the maximum shock absorption effect is provided at the distal end (the farthest distal end is the gripping surface 11 in contact with the hand), and the controllability is provided at the proximal end (the smaller the delay in the movement transfer from the proximal end to the rigid member, the better the controllability).

[0052] The thickness portion 13 is a multi - layer structure. See also Figures 1 to 8 , having a larger size in the radial direction and accommodating more radially extending ventilation holes 131 and axially extending ventilation holes 132 to further enhance the ventilation and shock absorption effects.

[0053] The grip 1 is made by 3D printing.

[0054] In addition, at least one end of the thickness portion 13 is formed with an annular first locking portion 133, F 锁紧-端部 >F 锁紧-中间部 It is achieved by at least one of the following:

[0055] The elastic modulus of the first locking portion 133 > the elastic modulus of the middle portion;

[0056] And in the state where the sleeve 1 and the rigid member are not assembled, the distance from the first locking portion 133 to the center > the distance from the middle portion to the center.

[0057] F 锁紧-中间部 Not being 0, an annular second locking portion 134 is constructed in the middle portion of the mounting surface 12. As Figure 2 and Figure 8 shown.

[0058] F 锁紧-中间部 Being 0, an annular locking portion is not constructed in the middle portion of the mounting surface 12. As Figure 4 and Figure 6 shown.

[0059] The second part of the embodiment of the present utility model discloses a holding handle, any of the above-mentioned sleeve 1 and rigid member.

[0060] Finally, the above-mentioned rigidity and elasticity are relative concepts, and it should be understood that under assembly or use (the force applied to the sleeve 1 and the rigid member under normal working conditions), the corresponding parts that can cause significant deformation are said to have elasticity, and those that do not cause significant deformation are said to have rigidity, which is not an absolute concept. For example, after the sleeve 1 is made of rubber, photocuring resin, etc., it can be stretched and expanded under a small pulling force, so as to be sleeved outside the rigid member. At this time, the sleeve 1 has elasticity (deforms under force), and the rigid member has rigidity (does not deform under force); when in use, the situation is the same. A specific application is that when the sleeve 1 is used as the holding part of a bicycle, the rider can cause significant elastic deformation of the sleeve 1 through holding and pressing, and cannot cause significant elastic deformation of the rigid member. At this time, the sleeve 1 has elasticity and the rigid member has rigidity.

[0061] The above-described embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model, and should all be included in the protection scope of the present utility model.
