Description

Technical Field

[0001] The present invention relates to the field of replaceable aids intended to be inserted into a grip handle or a knife. Specifically, the present invention provides aids such as kitchen utensils, camping tools, etc., configured to be removably attached to a grip handle. The present invention also proposes an assembly consisting of a handle and one or more aids that can form an aid kit.

Background Art

[0002] Several types of grip handles or manual instruments provided with different aids or tools are known, in particular tools comprising a handle and various tools that are detachable, i.e., removable, from the handle. For example, the most well-known is a manual instrument commonly called a "Swiss knife" that includes a block forming the handle. As the latter, several tools such as scissors, a file, a blade, a punch, a screwdriver, a corkscrew, a USB key, etc. are assembled in a method via joints along a transverse axis. This type of knife has the advantage that several tools with various respective functions can be grouped together in one instrument. However, considering the robustness and durability constraints related to the presence of several tools that are rotationally mounted, these structures are relatively complex, heavy, and costly to manufacture.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Therefore, it has been found that known manual instruments or grip handles have at least one or two or more of the following drawbacks.

[0004] · Complex structure · High manufacturing cost · Considerable weight · Difficult handling and attachment of aids (e.g., tools) • The handle (sideways) is inconvenient to use. • The attachment or placement of auxiliary tools (e.g., screwdrivers) when not in use may result in an inconvenient or complicated structure. [Means for solving the problem]

[0005] Furthermore, one of the objectives of the present invention is to overcome these drawbacks. For this purpose, the present invention An auxiliary device suitable for detachably attaching to a grip handle, wherein the grip handle is An inner housing formed at the end of the grip handle, The inner housing includes an opening having a first portion that opens to the end face of the grip handle and a second portion that opens to the side of the grip handle. The end face extends so as to be perpendicular to the direction of longitudinal extension of the grip handle. Inner housing and A rotating ferrule is rotatably mounted between a closed position in which the rotating ferrule at least partially covers the second portion of the opening and an open position in which the rotating ferrule opens the second portion of the opening, Equipped with, The auxiliary device includes an assembly portion configured to be detachably attached to the grip handle, The assembly portion is configured to be inserted into the inner housing, The auxiliary device includes a retaining portion configured to cooperate with the rotating ferrule when the rotating ferrule is in the closed position, so as to hold the assembly portion within the inner housing. I propose an assistive device.

[0006] Furthermore, users can plan to carry multiple auxiliary tools attached to a single handle. This reduces the weight of the tools carried by the user while improving usability and comfort. These auxiliary tools could be kitchen utensils such as spatulas, cutlery like forks and spoons, tools like awls, screwdrivers, or corkscrews, or any other functions.

[0007] The cooperation between the retaining part of the auxiliary device and the rotating ferrule not only ensures secure attachment of the auxiliary device to the handle but also provides safety during use, allowing the auxiliary device to be handled safely when the rotating ferrule is in the closed position.

[0008] In one example, the retaining portion includes a projection configured to be received in a circumferential groove provided on the inner surface of the rotating ferrule, so as to hold the assembly portion when the rotating ferrule is in the closed position.

[0009] In one configuration, the assembly portion includes an insertion portion configured to be received by the inner housing. Thus, the insertion portion completes a retaining portion for detachably attaching an auxiliary device within the grip handle.

[0010] Specifically, the insertion portion extends longitudinally along the main direction in which the auxiliary tool extends, so as to form a guide projection when the assembly portion is inserted into the inner housing. This configuration provides an angle vibration prevention mechanism for the auxiliary tool when it is inserted into the handle when the auxiliary tool is in use.

[0011] For example, the assembly portion has a thickness smaller than the width of the inner housing. The assembly portion includes a transverse portion that defines a projection on its upper surface, The projection is configured to be supported on the first inner surface of the inner housing, and the recess extending between the two support portions is limited on the lower surface opposite the assembly portion. The two support portions are configured to be supported by the second inner surface of the inner housing opposite to the first inner surface. This configuration prevents the auxiliary device fixed within the grip handle from moving excessively in the angular direction and facilitates the use of the auxiliary device.

[0012] According to one embodiment, the grip handle includes a swivel blade and a longitudinal groove formed from the end face, and the groove is partially shared with the opening of the inner housing. The aforementioned swivel blade is The swivel blade is housed in the longitudinal groove, and when the rotating ferrule is in the closed position, the rotating ferrule closes the swivel blade, and the inner wall of the longitudinal groove and the swivel portion define the contour of the inner housing, in a housed position, In the longitudinal direction of the grip handle, there is a usage position in which the swivel blade protrudes from the longitudinal groove, The swivel blade is provided with a swivel section that is rotatably mounted in the longitudinal groove so that it can rotate between the two sides. The assembly portion has a notch which is limited to an insertion portion on one side and a holding portion on the other. The notch is configured to have a shape complementary to the swivel portion so that it engages with the swivel portion within the inner housing when the assembly portion is inserted into the inner housing. The swivel ferrule is naturally in the closed position. The size of the assembly portion inserted into the inner housing is limited. The auxiliary tool protrudes slightly from the handle while remaining stable for optimal use of the functional portion. The functional portion is the part used by the user. For example, if the auxiliary tool is cutlery such as a fork, the functional portion is the fork tip. For a spoon, the functional portion is the recessed or concave end that forms the bowl.

[0013] In this different embodiment, the rotating ferrule means a safety ring comprising a fixing portion for securing to the grip handle and a rotating portion that allows the blade to be blocked in the open position and the blade to be blocked in the closed position, the auxiliary device being inserted into and secured to the handle.

[0014] According to one configuration, the auxiliary tool is configured to engage with an additional auxiliary tool, and the auxiliary tool includes engaging means configured to cooperate with complementary engaging means of the additional auxiliary tool so that the auxiliary tool and the additional auxiliary tool can engage with each other. This facilitates the storage of auxiliary tools that are not in use.

[0015] According to a second aspect, the present invention proposes a kit of auxiliary tools comprising an additional auxiliary tool including complementary engaging means and the above-described auxiliary tool.

[0016] According to one configuration, the engaging means and the complementary engaging means are configured such that when the engaging means is engaged with the complementary engaging means, corresponding portions of the assembly part and the functional part of the auxiliary tool and the additional auxiliary tool are overlapped. Thus, when the functional parts have complementary shapes, the size of the auxiliary tool kit is minimized by overlapping.

[0017] According to an example, the engaging means comprises or consists of a protrusion formed at a connecting part of the auxiliary tool that particularly connects the assembly part to the functional part of the auxiliary tool.

[0018] Conversely, the additional engaging means comprises a through cavity formed at a connecting part configured to particularly connect the assembly part to the functional part of the additional auxiliary tool.

[0019] According to yet another aspect, the present invention is an assembly including a grip handle, and the grip handle is an inner housing formed at an end of the grip handle, the inner housing includes an opening having a first part opening to an end face of the grip handle and a second part opening to a side part of the grip handle, the end face extends in a direction transverse to a direction of longitudinal extension of the grip handle, the inner housing, The rotary ferrule is rotatably attached between a closed position in which the rotary ferrule at least partially covers the second portion of the opening and an open position in which the rotary ferrule opens the second portion of the opening, and the rotary ferrule, comprising, proposes an assembly comprising at least one of the above-mentioned aids or the above-mentioned aid kit.

[0020] According to an example, the grip handle of the assembly includes a swivel blade and a longitudinal groove formed from the end face, and has a groove that partially shares the opening of the housing. The swivel blade, a storage position in which the swivel blade is housed in the longitudinal groove, the rotary ferrule closes the swivel blade when the rotary ferrule is in the closed position, and the inner wall of the longitudinal groove and the swivel portion define the contour of the inner housing, a use position in which the swivel blade projects from the longitudinal groove in the longitudinal direction of the grip, and is provided with a swivel portion rotatably attached to the longitudinal groove so that the swivel blade can swivel between them.

[0021] According to other features, the aid, the aid kit and all of the present invention include one or more of any of the following features considered alone or in combination.

[0022] · The side portion of the grip handle extends in the direction of the longitudinal extension of the grip handle. · Most of the assembly part is flat. · The holding portion extends longitudinally mainly along the main direction in which the aid extends. · The protrusion of the holding portion extends in a direction transverse to the main direction in which the aid extends. · The length of the insertion portion is longer than the length of the holding portion. · The insertion portion, the notch and the holding portion are configured such that the holding portion is inserted from the side of the second portion of the opening of the inner housing, and the insertion portion is inserted from the side opposite to the second portion of the opening.

[Figure 3] Figure 3 shows a schematic front view of an additional auxiliary device according to an embodiment of the present invention. [Figure 4] Figure 4 shows a schematic front view of the auxiliary tool and additional auxiliary tool kit and the engaging means according to an embodiment of the present invention. [Figure 5] Figure 5 shows a schematic diagram of the kit shown in Figure 4. [Figure 6] Figure 6 shows a cross-sectional view of the auxiliary device inserted into the handle. [Figure 7] Figure 7 shows another cross-sectional view of the auxiliary device inserted into the handle, opposite to that shown in Figure 6. [Modes for carrying out the invention]

[0024] As shown in Figures 1-3, the auxiliary tool 1 according to the present invention comprises an assembly part 2 intended to be detachably attached inside a grip handle 3 (Figures 6 and 7), a functional part 4 which is a spoon or fork, and a connecting part 5 which connects two other members 3 and 4. As will be described later (Figures 6 and 7), the assembly part 2 includes a holding part 6 (also shown in Figures 4 and 5) configured to cooperate with a rotating ferrule 7 provided on the grip handle 3 so as to hold the assembly part 2 inside the handle 3.

[0025] The grip handle 3 includes an inner housing 9 (Figures 6 and 7) at its end 8, which includes an opening 10 used particularly for introducing the assembly portion 2 of the auxiliary device 1. More specifically, the opening 10 includes a first portion that opens into the end face 11 of the grip handle 3, from which the connecting portion 5 and the functional portion 4 protrude when the assembly portion 2 is inserted. The end face 11 extends across the longitudinal direction X of the grip handle 3. The opening 10 also includes a second portion that opens onto the side surface of the handle 3, allowing a projection 12 provided on the holding portion 6 to cooperate with the rotating ferrule 7.

[0026] The handle's rotating ferrule 7 is rotatably mounted between a closed position in which the rotating ferrule 7 at least partially covers the second portion of the opening 10 and an open position in which the rotating ferrule 7 opens the second portion of the opening 10. The projection 12 of the holding portion 6 of the auxiliary tool 1 is configured to be received in a circumferential groove 13 provided on the inner surface of the rotating ferrule 7 so as to hold the assembly portion 2 inside the inner housing 9 when the rotating ferrule 7 is in the closed position (Figures 6 and 7).

[0027] As also shown in the figure, the assembly portion 2 includes an insertion portion 14 configured to be received by the inner housing 9. It extends longitudinally along the main direction in which the auxiliary tool 1 extends, so as to form a guide projection when the assembly portion 2 is inserted into the inner housing 9. This facilitates insertion into the housing 9 and also provides an effect of preventing angular vibration of the auxiliary tool 1 inserted into the handle 3. Thus, the insertion portion 14 gives good rigidity to the assembly 100 of the auxiliary tool 1 housed in the grip handle 3.

[0028] At the same time, the assembly portion 2 has a thickness smaller than the width of the inner housing 9, which facilitates insertion while compensating for any dimensional play that might hinder the use of the auxiliary tool 1. The assembly portion 2 includes a transverse portion on the upper surface 16 that defines a projection 15, enabling support by the first inner surface of the inner housing 9. Conversely, the projection 15 limits a recess 18 on the opposite lower surface 17 that extends between two support portions 17', enabling support on the opposite second inner surface. Thus, while being inserted into the housing, the assembly portion, which is thinner than the opening 10 of the inner housing 9, is guided by the guide projection, and then the projection 15 is supported on the first inner surface, and the two support portions formed by the two regions 17' of the lower surface 17 (Figure 2) are supported on the opposite second inner surface, limiting the angular distortion of the assembly portion 2 once inserted into the inner housing 9.

[0029] In an embodiment of the present invention (shown in Figures 6 and 7) in which the grip handle 3 is equipped with a swivel blade 19, the longitudinal groove 20 is formed from the end face 11 of the grip handle 3 having a slot, and a portion of the grip handle is shared with the opening 10 of the inner housing 9. Specifically, the swivel blade 19 is equipped with a swivel portion 21 that is swivelably mounted within the longitudinal groove 20. This ensures that the swivel blade 19 can rotate between a storage position in which the swivel blade 19 is housed within the longitudinal groove 20 (shown in Figures 6 and 7) and a usage position (not shown) in which the swivel blade 19 protrudes from the longitudinal groove 20 in the longitudinal direction X of the handle 3.

[0030] In the retracted position of the swivel blade 19, the inner wall of the longitudinal groove 20 and the swivel portion 21 define the contour of the inner housing 9 that can receive the auxiliary tool 1. At the same time, the assembly portion 2 is provided with notches 22 that are limited on both sides of the insertion portion 14 and the holding portion 6, having a shape complementary to the swivel portion 21 in order to enable fitting with the swivel portion 21 when the assembly portion 2 is inserted into the inner housing 9.

[0031] In embodiments where the grip handle 3 does not have a swivel blade 19, the auxiliary tool 1 also includes a notch 22 with a shape complementary to the shape of the inner housing 9.

[0032] As shown in Figures 1-5, the auxiliary tool 1, such as a spoon (Figures 1 and 2), is configured to engage with an additional auxiliary tool 1' (here, a fork, Figure 3) by overlapping it with the auxiliary tool 1', which is shown here as a protruding portion 23 (Figures 2 and 4) and formed on the connecting portion 5 of the auxiliary tool 1. The engaging means 23 is configured to overlap with a complementary engaging means 24, which is shown here as a through-hole provided on the additional auxiliary tool 1' (Figure 3). When the shapes of the assembly portion 2, functional portion 4, and connecting portion 5 of the auxiliary tool 1 and the additional auxiliary tool 1' are complementary, the two components of the auxiliary tool 1 and the additional auxiliary tool 1' become one (Figures 4 and 5), forming a kit 30.

[0033] When in use, with the rotating ferrule 7 in the open position, the swivel blade 19 is rotatable in the retracted position within the longitudinal groove 20, and the assembly portion 2 of the auxiliary tool 1 can be inserted into the inner housing 9, for example, into the joint until the notch 22 abuts against the swivel portion 21. To cooperate with the rotating ferrule 7, the retaining portion 6 is positioned on the side of the second portion of the opening 10. Thus, the rotating ferrule 7 can rotate from its open position to a closed position where the circumferential groove 13 cooperates with the projection 12 of the retaining portion 6 to secure the auxiliary tool 1 in the grip handle 3. At the same time, the rotating ferrule 7 closes the swivel blade 19. For example, if the user wishes to use the swivel blade 19 of the auxiliary tool 1 or replace the auxiliary tool 1, the user moves the rotating ferrule 7 from the closed position to the open position. Then, to allow the auxiliary tool 1 to be removed from the inner housing 9, the retaining portion 6 is positioned in front of the groove of the rotating ferrule 7, which is adjacent to the longitudinal groove 20. The swivel portion 21 of the swivel blade 19 is disengaged from the notch 22 and faces the groove of the rotating ferrule 7, so that the blade 19 can swivel to the working position, where the blade 19 extends outside the longitudinal groove 20 in the longitudinal direction X of the handle 3.

[0034] Therefore, the present invention proposes an auxiliary device 1 that is cleverly designed to be easily inserted into the handle 3 and is detachably attached to the grip handle 3. The auxiliary device 1 is also well thought out to provide stability to the handle 3, preventing axial or angular displacement during use. The fact that a rotating ferrule 7 is used also allows the auxiliary device 1, once received by the handle 3, to remain immobile. Furthermore, the engaging means 23, 24 provided on the auxiliary device 1 and the additional auxiliary device 1' limit the size of the kit 30, enabling optimal storage.

[0035] Needless to say, the present invention is not limited to the embodiments described above as examples, but includes all technical equivalents and variations of the means described, and combinations thereof.
