Summary of the Invention

Problems to be Solved by the Invention

[0004] Patent Document 1 describes a configuration in which a protective member (grip member) is attached to a rod-shaped handle member in a cart. This protective member has a grip portion that a user holds and a protective portion that protrudes outward from the grip portion, and this protective portion enables the user's fingers to be protected from surrounding objects.

[0005] The protective member described in Patent Document 1 is configured to be assembled to the cart by inserting the end portion of the handle member of the cart (or inserting it into the end portion of the handle member). For this reason, when a cap is attached to the end portion of the handle member, it is necessary to remove the cap and assemble it. Also, when the end portions of two handle members are continuous in a U-shape or the like, the protective member cannot be attached.

[0006] On the other hand, when the grip member is assembled from the side of the handle member, it is difficult to ensure sufficient strength in the assembly of the grip member to the handle member. As a result, there was a possibility that the grip member would rotate or slide in the axial direction of the handle member during use.

[0007] The present invention has been made in view of the above circumstances, and the problem that the present invention aims to solve is to provide a trolley grip and trolley that can be assembled from the side of the handle member and that can sufficiently secure the assembly strength to the handle member, thereby protecting the user's fingers. [Means for solving the problem]

[0008] To solve the aforementioned problems, the present invention provides the following grip for a trolley.

[0009] (1) A grip for a trolley comprising: a first member having an assembly portion arranged along the side surface of a rod-shaped handle member on a trolley, and a protective portion extending radially outward from the handle member, spanning one end and the other end of the handle member in the axial direction at the assembly portion; and a second member arranged opposite to the assembly portion of the first member, wherein the grip is assembled to the handle member by combining the assembly portion and the second member while the handle member is sandwiched between the assembly portion and the second member.

[0012] (2) The trolley grip described in (2) can be assembled from the side of the handle member with a simple configuration.

[0013] (3) The trolley grip according to (2), wherein, when the engaging projection is inserted into the engaging hole, at least one of the engaging projections breaks due to an external force pulling it out of the engaging hole.

[0014] (3) The trolley grip described above can be made unusable after being assembled to the handle member.

[0015] (4) The trolley grip according to (1), wherein at least one elastic projection is formed on the surface facing the side of the assembly portion and the second member, the elastic projection protrudes toward the side of the side and contacts the side, causing it to elastically deform radially outward of the handle member.

[0016] (4) The trolley grip described in (4) makes it impossible to insert and assemble the handle member while the first member and the second member are engaged.

[0017] (5) The trolley grip according to (1), wherein at least one of the assembly portion and the second member has two protruding portions formed on the surface facing the side surface, along the axial direction of the handle member.

[Modes for carrying out the invention]

[0030] A trolley grip 1 according to one embodiment of the present invention will be described with reference to Figures 1 to 9. As shown in Figures 4 and 5, the trolley grip 1 is used when assembled to a trolley C. The trolley C is composed of a trolley body M with wheels on its bottom surface and four rod-shaped handle members B provided on the trolley body M.

[0031] Furthermore, the trolley grip 1 can also be attached to a trolley in which the trolley body and the handle member are integrally formed. Also, the number of handle members B attached to the trolley body M is not limited to this embodiment, and other numbers besides four can be used. In addition, although the handle member B is formed in a hollow cylindrical shape in this embodiment, the handle member B can also be made in a solid cylindrical shape. Furthermore, the cross-sectional shape of the handle member B can be a polygonal shape other than a circle.

[0032] In this embodiment, the trolley grip 1 is attached to a pair of left and right handle members B·B on the front side (user U side) of the trolley body M. In Figures 4 and 5, the trolley grip 1 attached to the right handle member B as viewed from the user U is referred to as the right grip 1R, and the trolley grip 1 attached to the left handle member B as viewed from the user U is referred to as the left grip 1L.

[0033] The right grip 1R and the left grip 1L are attached to the handle member B in a 180-degree inverted position relative to each other, by inverting the same-shaped trolley grip 1 vertically. It is also possible to configure the trolley grip 1 to be attached to each of the four handle members B.

[0034] As shown in Figure 5, the trolley grips 1 (right grip 1R and left grip 1L) are assembled to the handle member B such that the protective part 22, described later, extends laterally from the trolley body M in a plan view. When the user U operates the handle member B of the trolley C, they insert their fingers inside the protective part 22. This prevents the user U's fingers from hitting surrounding objects such as walls or other luggage, or from getting caught between the handle member B and surrounding objects, thereby protecting the user U's fingers.

[0035] As shown in Figures 1 to 3, the trolley grip 1 according to this embodiment is constructed by engaging and combining a first member 2 and a second member 3 with each other. The first member 2 and the second member 3 are each made of a hard resin material.

[0036] The first member 2 is formed with an assembly portion 21 that is roughly semi-cylindrical in shape, and a protective portion 22 that extends outward from the outer circumferential surface of the assembly portion 21. As shown in Figure 6, the assembly portion 21 is positioned vertically so as to abut against the outer surface of the handle member B. A first projection 21a is formed on the outer circumferential surface of the assembly portion 21, protruding vertically in a direction perpendicular to the extension direction of the protective portion 22 in a plan view. The first projection 21a functions as an anti-slip feature when the user U operates the handle member B.

[0037] The protective portion 22 spans one axial end (upper end) and the other end (lower end) of the handle member B in the assembly portion 21 and extends radially outward from the handle member B. Multiple protrusions 22a are formed horizontally on the outer surface of the protective portion 22. In this embodiment, the protrusions 22a prevent the outer surface of the protective portion 22 from becoming dirty or scratched.

[0038] As shown in Figure 3, the assembly portion 21 of the first member 2 has four engagement holes 23 formed on the surface facing the second member 3. In addition, a resistance member 24 is provided on the inner surface of the assembly portion 21 to increase the frictional force with the handle member B when the trolley grip 1 is assembled to the handle member B. In this embodiment, the resistance member 24 is a rubber plate-shaped member.

[0039] As shown in Figures 1 to 3, a display section 25 indicating the assembly direction to the trolley C is formed on the upper surface of the first member 2. The user U of the trolley C can attach the trolley grip 1 to the handle member B according to the display section 25, thereby causing the protective section 22 to extend laterally from the trolley body M in a plan view (see Figures 4 and 5).

[0040] In this embodiment, a display unit 25 is formed on the lower surface of the first member 2, similar to the upper surface. Therefore, as shown in Figures 4 and 5, even when the trolley grip 1 is used upside down, the user U of the trolley C can see the display unit 25 from above the trolley grip 1.

[0041] As shown in Figure 3, the second member 3 is engaged with the first member 2 in a position facing the engagement hole 23 of the first member 2. Specifically, the second member 3 has four engagement protrusions 31 formed on the surface facing the first member 2. By inserting each of the engagement protrusions 31 into the engagement hole 23 of the first member 2, the assembly portion 21 and the second member 3 are engaged.

[0042] On the outer circumferential surface of the second member 3, a second projection 3a is formed, protruding vertically in the opposite position to the first projection 21a of the assembly portion 21. The second projection 3a functions as an anti-slip feature when the user U operates the handle member B.

[0043] As shown in Figure 3, two elastic protrusions 32-32 are formed on the inner circumferential surface of the second member 3 (the surface facing the side of the handle member B), projecting toward the inside of the trolley grip 1 (towards the side of the handle member B). As shown in Figure 7, when the trolley grip 1 is assembled to the handle member B, the elastic protrusions 32-32 come into contact with the side of the handle member B and elastically deform radially outward from the handle member B.

[0044] As shown in Figure 3, two protrusions 33,33 are formed on the inner circumferential surface of the second member 3, running vertically. As shown in Figures 7 and 8, the protrusions 33,33 contact the side surface of the handle member B when the trolley grip 1 is assembled to the handle member B, thereby supporting the handle member B.

[0045] When assembling the trolley grip 1 to the handle member B, as shown in Figure 6, the handle member B is sandwiched between the assembly portion 21 of the first member 2 and the second member 3. Then, in this state, the engagement hole 23 of the assembly portion 21 and the engagement projection 31 of the second member 3 are engaged. In this way, the handle member B is held between the assembly portion 21 and the second member 3, thereby assembling the trolley grip 1 to the handle member B.

[0046] As described above, the trolley grip 1 according to this embodiment can be assembled from the side of the handle member B. Therefore, even if the handle member B has a cap at its end, or if the ends of the two handle members are continuous in a U-shape or the like, the trolley grip 1 can be assembled.

[0047] Furthermore, the trolley grip 1 according to this embodiment is configured to be assembled to the handle member B by combining the assembly portion 21 and the second member 3, with the handle member B sandwiched between the assembly portion 21 and the second member 3 of the first member 2. In this way, the handle member B is sandwiched between two members, so the assembly strength of the trolley grip 1 to the handle member B can be ensured. Therefore, the possibility of the trolley grip 1 rotating or the handle member B sliding during use can be reduced.

[0048] Furthermore, in this embodiment, the trolley grip 1 is configured such that the assembly portion 21 and the second member 3 engage by inserting the engaging projection 31 of the second member 3 into the engaging hole 23 of the first member 2. This allows the trolley grip 1 to be assembled to the handle member B simply by bringing the first member 2 and the second member 3 close together with the handle member B in between. In other words, the trolley grip 1 can be assembled to the handle member B from the side with a simple configuration.

[0049] In the trolley grip 1 according to this embodiment, the engaging projection 31 is formed with a shape in which the tip is divided into two parts, as shown in Figures 6, 8, and 9, thereby reducing its strength compared to other parts. As a result, if an external force is applied in the direction of pulling the engaging projection 31 out of the engaging hole 23 while the engaging projection 31 is inserted into the engaging hole 23, at least one of the engaging projection 31 is configured to break. In this way, by making it impossible to reuse the trolley grip 1 after it has been assembled to the handle member B, it is possible to prevent the use of a trolley grip 1 that has been used once and whose assembly strength has decreased.

[0050] In the trolley grip 1 according to this embodiment, elastic projections 32-32 are formed on the inner circumferential surface of the second member 3, which protrude toward the side of the handle member B and contact the side, causing elastic deformation radially outward of the handle member B. The elastic projections 32-32 prevent the handle member B from being inserted and assembled while the first member 2 and the second member 3 are engaged.

[0051] In other words, even if one attempts to insert the handle member B while the first member 2 and the second member 3 are engaged, the handle member B will catch on the elastic projection 32, making assembly impossible. Thus, in this embodiment, it is prevented to remove the handle member B from the trolley grip 1 and reuse it after it has been assembled to the trolley grip 1.

[0052] In the trolley grip 1 according to this embodiment, two protrusions 33, 33 are formed on the inner circumferential surface of the second member 3 along the axial direction of the handle member B. This limits the contact area between the inner circumferential surface of the second member 3 and the handle member B, thereby increasing the assembly strength of the trolley grip 1 to the handle member B.

[0053] In the trolley grip 1 according to this embodiment, a resistance member 24 is provided on the inner circumferential surface of the assembly portion 21 of the first member 2 to increase the frictional force with the handle member B. This makes it possible to further increase the assembly strength of the trolley grip 1 to the handle member B through the frictional force of the resistance member 24.

[0054] In this embodiment, the upper and lower surfaces of the trolley grip 1 are formed with display units 25 that indicate the assembly direction to the trolley C. This makes it easier for the user U to determine the assembly orientation of the trolley grip 1 to the trolley C.

[0055] In the trolley grip 1, the first member 2 and the second member 3 can be formed with different rigidities. For example, the rigidity of the second member 3 can be made lower than that of the first member 2, making it more elastically deformable. This allows the member with the lower rigidity of the two members, the first member 2 and the second member 3, to be elastically deformed, and its elastic force can be used to assemble it to the handle member B.

[0056] In this embodiment of the trolley grip 1, the configuration is shown in which the first member 2 is positioned on the front side (the user U's side) as shown in Figures 4 and 5, but it is also possible to position the second member 3 on the front side.

[0057] In the trolley grip 1 according to this embodiment, the first member 2 and the second member 3 are combined by engaging the engaging projection 31 with the engaging hole 23. However, the method of combining the first member 2 and the second member 3 is not limited to this embodiment. For example, it is also possible to combine the first member 2 and the second member 3 using connectors such as screw members or clip members, or to combine the first member 2 and the second member 3 by adhesive or heat welding.

[0058] Furthermore, in the trolley grip 1, it is also possible to provide the resistance member 24 on the second member 3. It is also possible to provide the resistance member 24 on both the first member 2 and the second member 3.

[0059] Furthermore, in the trolley grip 1, it is also possible to provide the elastic projection 32 and the protruding portion 33 on the first member 2. It is also possible to provide the elastic projection 32 and the protruding portion 33 on both the first member 2 and the second member 3.

[0060] Furthermore, in the trolley grip 1, the display section 25 can be formed on either the top or bottom surface. Also, the display method in the display section 25 can include methods such as attaching a sticker, or printing a mark, text, or a combination thereof. [Explanation of symbols]
