Description

Technical Field

[0001] The present invention relates to a blade storage case for storing a metal blade carried by an operator.

Background Art

[0002] Conventionally, for sharp tools such as saws carried by operators, a configuration in which the blade part is stored in a sheath has been used for safety during carrying.

[0003] In this regard, for example, when a saw was conventionally inserted and removed through an opening at the upper part of the sheath, in view of the problem that the opening was narrow and it was difficult to insert a saw with a long blade width, a configuration was proposed in which a vertically long opening was provided on one side surface of the sheath to facilitate the insertion of the saw from the side surface (see Patent Document 1).

[0004] However, when an opening is provided on the side surface, if the opening is too large, not only may the protection of the blade be insufficient, but also the saw may be detached from the sheath. Therefore, consideration is required for the mode (position, length, width, etc.) of the opening.

[0005] On the other hand, a configuration in which a cavity corresponding to the shape of the blade part is formed and the blade part is inserted and stored into the cavity from the upper side is generally used as a sheath for sharp tools (see Patent Document 2).

[0006] Also, from the viewpoints of weight reduction and easy insertion of the sheath, it has been pointed out that a cylindrical sheath is bulky and heavy, and there are inconveniences such as a troublesome operation of inserting the tip into the open end. A sheath using a magnet as a holding means (magnetic attachment holding) has also been mentioned (see Patent Document 3). Furthermore, depending on the mode of the holding means, an increase in the attachment / detachment resistance may make the attachment / detachment operation difficult to perform smoothly, and it has also been sorted out as a problem that the simplicity may be impaired.

[0008] However, with top-insertion type sheaths, it is necessary to insert the blade lengthwise while checking the insertion opening, which can be particularly difficult with long blades. Furthermore, the sheath itself tends to be bulky and hinders work. For this reason, it is conceivable to facilitate the insertion operation by providing a longitudinally elongated opening on the side of the case body, allowing the blade to be inserted laterally through this opening.

[0009] However, if a vertically elongated opening is provided on the side, there is a risk that the blade may pop out of the sheath if the opening is too large, making it challenging to balance ease of lateral insertion with secure retention (prevention of detachment). Furthermore, depending on the type of retaining mechanism, resistance may be created when attaching and detaching the blade, making the attachment and detachment operation difficult and potentially hindering ease of use.

[0010] Therefore, the present invention aims to provide a blade storage case and a method for storing a blade using the same, which allows the blade to be inserted laterally through a vertically elongated opening on the side and housed in the case body, while ensuring safety by preventing it from detaching towards the vertically elongated opening on the side, and further ensuring ease of storage and retrieval by allowing the blade to be pulled out longitudinally from an opening on the shorter side. [Means for solving the problem]

[0011] As a result of diligent research to solve the above problems, the inventors of this invention have found a blade storage case configuration that allows a metal blade to be easily stored by lateral insertion, while ensuring safety by preventing it from detaching towards the vertically elongated opening on the side, and further ensuring operability by allowing it to be pulled out from the short side.

[0012] In other words, the blade storage case of the present invention is a blade storage case capable of accommodating a metal blade, comprising a case body that extends in the longitudinal direction and is configured to accommodate the blade in an internal space, an opening formed on one short side of the case body from which the blade can be pulled out in the longitudinal direction, a longitudinally elongated opening formed on the side of the case body, the longitudinally elongated opening extending to a extent that allows the tip of the blade to be stored to be introduced from the side and enter the internal space, and a magnet capable of adsorbing onto the blade is provided on the inner surface portion of the case body that faces the longitudinally elongated opening.

[0013] Furthermore, in one embodiment of the present invention, a locking piece is formed along the edge of the vertically elongated side opening of the case body, and when a force is applied to the blade body having a component toward the vertically elongated side opening and in a direction intersecting the longitudinal direction, the blade body abuts against the locking piece, restricting its movement toward the vertically elongated side opening. Moreover, the locking piece is formed along the edge of the vertically elongated side opening, and at least a portion of it is aligned with the longitudinal direction of the case body.

[0014] In another embodiment of the present invention, the case body comprises a central member, a base member attached to one longitudinal end of the central member, and a tip member attached to the other longitudinal end of the central member. Here, the locking piece is formed on the central member, but not on the base member or the tip member.

[0015] Furthermore, the thickness of the central member is smaller than the thickness of the base member and the tip member, and the base member and the tip member each grip a part of the corresponding end of the central member to define their relative positions, while projections provided on the inside of each member are inserted into holes formed in the central member and fixed to the central member.

[0016] Furthermore, the central member has multiple holes spaced apart in the longitudinal direction that define the mounting position of the base member, and multiple holes spaced apart in the longitudinal direction that define the mounting position of the tip member, and the length of the blade storage case can be adjusted in steps by selectively inserting the projection of the base member and the projection of the tip member into one of the multiple corresponding holes.

[0017] Furthermore, the base member and the tip member are configured to be attached to the central member in the opposite direction to the mounting direction. In addition, the tip member has an open portion on the other end in the longitudinal direction, so that foreign matter adhering to the blade body can fall off.

[0018] In another embodiment of the present invention, the magnet is embedded in the resin material of the case body.

[0019] Furthermore, the present invention also includes a method for storing a blade using the blade storage case described in claim 1, which includes the steps of: inserting the blade from the side through the vertically elongated side opening, sliding the blade into the case body through the vertically elongated side opening in a direction intersecting the longitudinal direction toward the internal space; and pulling the blade out in the longitudinal direction from the opening to remove it. [Effects of the Invention]

[0020] According to the invention described in claim 1, the vertically elongated side opening extends to a range that allows the tip of the blade to be introduced from the side and enter the internal space, so that the blade can be slid in from the side for storage, making the insertion operation easier. In addition, the blade can be held in place by magnets provided on the inner surface facing the vertically elongated side opening, preventing it from detaching towards the vertically elongated side opening and increasing safety during carrying. Furthermore, the blade can be pulled out in the longitudinal direction from the opening on the short side, ensuring operability by separating storage (side) and removal (short side).

[0021] According to the invention described in claim 2, since it has a locking piece that projects inward along the edge of the vertically long side opening, and when a force in a direction intersecting the longitudinal direction and having a direction component toward the vertically long side opening is applied to the blade body, the blade body abuts against the locking piece and its movement is restricted, lateral escape toward the vertically long side opening side can be more reliably suppressed, and safety can be further improved.

[0022] According to the invention described in claim 3, since the locking piece is formed along at least a part of the longitudinal direction along the edge of the vertically long side opening, while ensuring the function of suppressing detachment toward the vertically long side opening side, the formation range of the locking piece can be set with a high degree of design freedom, and optimization according to manufacturability and application can be easily achieved.

[0023] According to the invention described in claim 4, since the case body is composed of a plurality of members such as a central member, a base end member, and a tip end member, the design freedom is increased from the viewpoints of assemblability and commonality of members, and it becomes easy to select a configuration according to the application and size.

[0024] According to the invention described in claim 5, since the locking piece is formed on the central member and not on the base end member and the tip end member, the range where the locking piece is provided is concentrated on the central member, making it easier to design and form, and it is easy to ensure the shape freedom on the end member side. Thereby, while ensuring the locking function necessary for suppressing detachment toward the vertically long side opening side, it is easy to optimize the end member according to the application and size (such as shape design around the opening, ensuring durability, etc.).

[0025] According to the invention described in claim 6, since the thickness of the central member is made smaller than that of the end member, and the end member sandwiches a part of the end of the central member and is fixed by the engagement of the protrusion and the hole, the positioning and fixing of the members are simple, and it is easy to obtain a reliable assembled state.

[0026] According to the invention described in claim 7, by providing a plurality of holes spaced apart in the longitudinal direction in the central member and selectively inserting the protrusion of the end member into any of the holes, the case length can be adjusted stepwise, and the applicable range according to the length of the blade body and the like can be expanded.

[0027] According to the invention described in claim 8, since the base member and the tip member are configured to be attached in opposite directions to the central member, there is a high degree of freedom in selecting the attachment method, and it is easy to optimize the handling according to the usage environment and carrying method.

[0028] According to the invention described in claim 9, since an open portion is provided on the other end in the longitudinal direction of the tip member, foreign matter adhering to the blade body can easily fall off, reducing the accumulation of dirt during carrying and use, and improving maintainability.

[0029] According to the invention described in claim 10, since the magnet is embedded in the resin material, the blade can be attracted and held while suppressing the protrusion of the magnet, which can contribute to stabilizing the blade's hold and improving its durability against external forces and impacts.

[0030] According to the invention described in claim 11, the process includes inserting the blade body laterally through a vertically elongated opening on the side and sliding it in a direction intersecting the longitudinal direction to house it, and pulling out the blade body from the opening on the short side. Therefore, the storage and removal of the blade body can be organized as different operations, and a series of operations during work can be performed smoothly.

[0031] Furthermore, the features of the blade storage case and blade storage method of the present invention, which allow the blade to be inserted laterally through a vertically elongated opening on the side and housed in the case body, while preventing it from detaching towards the vertically elongated opening on the side to ensure safety, and further enabling the operation of pulling the blade out longitudinally from an opening on the shorter side to ensure ease of storage and retrieval, are not described at all in the aforementioned Patent Documents 1 to 3.

[0032] Specifically, in contrast to the configuration described in Patent Document 1, which features a vertically elongated opening on the side, the present invention employs a separate insertion / removal mechanism that separates lateral insertion from the vertically elongated side opening 4 and longitudinal withdrawal from the opening 3 on the shorter side, allowing for compact insertion and removal of the blade SW. Furthermore, unlike the upward insertion type sheath described in Patent Document 2, even with a long blade SW, it is less necessary to insert it significantly in the longitudinal direction while visualizing the insertion opening, allowing for smooth storage even in confined spaces. In addition, regarding magnetic holding as described in Patent Document 3, by combining magnetic holding by magnet 5 with movement restriction by locking piece 6 along the edge 4E of the vertically elongated side opening 4, even when external force attempts to displace the blade SW towards the vertically elongated side opening 4, protrusion toward the vertically elongated side opening 4 can be suppressed. These points are neither described nor suggested in Patent Documents 1 to 3. [Brief explanation of the drawing]

[Figure 8] This is a schematic diagram showing the relationship between the suction holding of the blade body and the restriction of its movement toward the vertically elongated opening side by the locking piece according to an embodiment of the present invention. [Modes for carrying out the invention]

[0034] A blade storage case and a method for storing blades according to embodiments of the present invention will be described with reference to Figures 1 to 8. In the following, a blade storage case 1 for accommodating metal blades such as saw blades will be given as an example of a blade storage case.

[0035] In this specification, "longitudinal direction" refers to the direction in which the case body 2 extends. "Short side" refers to the longitudinal end (end face) of the case body 2. "Tip" refers to the cutting edge end of the blade, including the cutting edge (the end opposite to the backing plate and handle side). Furthermore, as shown in Figure 1, the upper side in the longitudinal direction is the base end, the lower side is the tip end, and the inner (body side) and outer sides, as well as the front and rear sides, follow the arrows in Figure 1.

[0036] As shown in Figures 1 and 2, the blade storage case 1 comprises a case body 2 that extends in the longitudinal direction and is configured to accommodate the blade in its internal space. The case body 2 has an opening 3 on one of its shorter sides (base end side) in the longitudinal direction, and the blade SW can be removed by pulling it out in the longitudinal direction through this opening 3.

[0037] A longitudinally elongated opening 4 is formed on the side of the case body 2, extending in the longitudinal direction. The longitudinally elongated opening 4 extends to a extent that allows the tip (blade edge side end) of the blade body SW to be housed to be introduced from the side and enter the internal space. Here, "the extent to which the tip of the blade body SW can be introduced from the side and enter the internal space" refers to the longitudinal range in which at least the tip of the blade body SW can pass through the longitudinally elongated opening 4 and enter the internal space beyond the edge 4E, and it is not intended that this longitudinal range is arbitrarily expanded depending on the manner of use, such as the insertion angle. Therefore, after the blade body SW is inserted from the side through the longitudinally elongated opening 4, it is slid in a direction intersecting the longitudinal direction toward the internal space and housed in the internal space of the case body 2. Here, "direction intersecting the longitudinal direction" refers to the direction including the thickness direction (side) of the case body 2. The blade body SW is removed by pulling it out longitudinally from the opening 3, which is a different route from lateral insertion.

[0038] As shown in Figures 1 and 2, the case body 2 comprises a central member 21, a base member 22 attached to the base end of the central member 21, and a tip member 23 attached to the tip end of the central member 21. These three members constitute the blade storage case 1 (this embodiment will be described as the best mode). The vertically elongated side opening 4 is formed on the side of the case body 2. Furthermore, a locking piece 6 (see Figure 3), which will be described later, is formed on the central member 21. In this embodiment, the locking piece 6 is not formed on the base member 22 and the tip member 23.

[0039] Next, the configuration of the central member 21 will be described with reference to Figures 3 and 4. The central member 21 has side walls facing each other on the inside (body side) and outside, and forms an internal space for housing the blade SW between these side walls. The internal space is formed by the opposing side walls 21A and 21B of the central member 21 and the back wall 21C that connects these side walls 21A and 21B. A vertically elongated opening 4 is formed on the side surface of the central member 21, and a locking piece 6 that protrudes inward from the case body 2 is formed along the edge 4E of the vertically elongated opening 4. Here, the edge 4E refers to the opening edge (opening periphery) that forms the vertically elongated opening 4.

[0040] Figure 4(B) shows DR1 as an example of the direction of movement (sliding direction) when introducing the blade SW into the internal space through the vertically elongated side opening 4. That is, after the blade SW is inserted laterally through the vertically elongated side opening 4, it is moved in the direction of DR1 to a position where it can be attracted and held by the magnet 5.

[0041] The locking piece 6 is formed along the edge 4E of the vertically elongated side opening 4 and is configured to protrude inward from the case body 2 in at least a portion of its length. The locking piece 6 does not need to be continuous along the entire length of the edge 4E; it is sufficient for it to be formed in at least a portion of its longitudinal direction along the edge 4E (in this example, it is formed in the positions shown in Figures 3 and 4). By configuring the locking piece 6 to "protrude inward along the edge 4E in at least a portion of its length," design flexibility can be ensured while restricting movement toward the vertically elongated side opening 4. The formation range of the locking piece 6 is not limited to continuous along the entire length of the edge 4E, but also includes configurations where it is partially formed within a range effective for restricting movement.

[0042] A magnet 5 capable of being attracted to the blade SW is provided on the inner surface of the side wall portion 21A of the central member 21 that faces the vertically elongated side opening 4. The magnet 5 is preferably embedded in the resin material constituting the side wall portion 21A, and positioned so that the magnetic surface of the magnet 5 is substantially flush with the inner surface of the side wall portion 21A. Furthermore, by providing the magnet 5 on the inner surface of the side wall portion 21A that faces the body, as in this embodiment (best mode), the case body 2 is supported along the body when worn, and rattling of the case body 2 caused by the magnetic force of the blade SW is easily suppressed. The embedding of the magnet 5 can be achieved, for example, by placing the magnet 5 in the mold during resin molding and performing insert molding, or by placing the magnet 5 in a housing recess formed in the resin material after molding and sealing it with resin or adhesive.

[0043] This prevents the magnet 5 from protruding and causing the blade SW to become unstable, while simultaneously holding the blade SW in place by attraction to the inner side, thus suppressing inadvertent movement or protrusion towards the vertically elongated opening 4 on the side.

[0044] Furthermore, in the state where the blade SW is held by magnet 5, it is not necessary for the blade SW to be in constant contact with the locking piece 6; it is sufficient that when the blade SW is displaced toward the vertically elongated opening 4 on the side due to an external force, it comes into contact with the locking piece 6 and its movement is restricted.

[0045] Furthermore, it is desirable that the magnetic force of the magnet 5 be set to an attractive force that prevents the blade SW from accidentally falling out while not hindering the longitudinal pulling operation from the opening 3. Specifically, by appropriately adjusting the number of magnets 5, the magnetic flux density, or the minute gap (clearance) between the attractive surface of the magnet 5 and the blade SW, it is possible to achieve both secure magnetic attachment during storage and smooth detachment during removal.

[0046] On the other hand, if an external force is applied to the blade SW toward the lateral vertical opening 4, the blade SW will come into contact with the locking piece 6, restricting its movement toward the lateral vertical opening 4. In other words, the magnet 5 contributes to stable holding in the normal state, and the locking piece 6 prevents detachment by coming into contact with and restricting movement when a force is applied toward the lateral vertical opening 4. This makes it possible to achieve both ease of lateral insertion and safe holding (prevention of detachment). Here, "force toward the lateral vertical opening 4" refers to a force acting on the blade SW that includes at least a component in the direction toward the lateral vertical opening 4 (a component in the direction intersecting the longitudinal direction).

[0047] Furthermore, the shape of the locking piece 6 is not limited to a slit-like (linear) shape extending in the longitudinal direction as shown in the figure. For example, it may be configured as a plurality of dot-like projections intermittently arranged along the longitudinal direction, or as a wave-like uneven surface. In this way, as long as the locking piece 6 has a shape that can restrict the movement of the blade SW in the thickness direction, the same effects as in this embodiment can be achieved regardless of its specific form. This allows for flexible design changes according to manufacturing costs and ease of resin molding. Note that the locking piece 6 includes a portion formed in a protruding or uneven shape, as long as it is configured to protrude inward from the case body 2 along the edge 4E that forms the vertically elongated opening 4 on the side.

[0048] Next, the configuration of the base member 22 and the tip member 23 and their attachment to the central member 21 will be described. As shown in Figure 5, the base member 22 is a member attached to the base end of the central member 21, and projections 92A and 92B are provided on the inside of the base member 22. Projection 92A is inserted into either hole 81a or 82a formed in the central member 21, and projection 92B is inserted into either hole 81b or 82b. Here, if projection 92A is inserted into hole 81a, projection 92B is inserted into hole 81b, and if projection 92A is inserted into hole 82a, projection 92B is inserted into hole 82b. Note that WD1 shown in Figure 5 indicates the width (clampable width) in which the base end side wall portions 21A and 21B of the central member 21 can be positioned inside the side wall portions 22A and 22B of the base member 22.

[0049] As shown in Figure 6, the tip member 23 is a member attached to the tip end of the central member 21, and projections 93A and 93B are provided on the inside of the tip member 23. Projection 93A is inserted into either hole 83a or 84a formed in the central member 21, and projection 93B is inserted into either hole 83b or 84b. Here, if projection 93A is inserted into hole 83a, projection 93B is inserted into hole 83b, and if projection 93A is inserted into hole 84a, projection 93B is inserted into hole 84b. Also, WD2 shown in Figure 6 indicates the width (clampable width) in which the tip side wall portions 21A and 21B of the central member 21 can be positioned inside the side wall portions 23A and 23B of the tip member 23.

[0050] Here, the central member 21 is formed with a smaller thickness than the base member 22 and the tip member 23. As a result, the base member 22 and the tip member 23 clamp a portion of the corresponding end of the central member 21 inside the side walls 22A, 22B (or 23A, 23B), respectively, and this clamping defines their relative positions in the thickness and width directions. Furthermore, in the clamped state, the end members (base member 22, tip member 23) are securely fixed to the central member 21 by inserting and engaging the projections 92A, 92B, 93A, 93B provided on the inside of each member into corresponding holes formed in the central member 21.

[0051] By ensuring clamping widths WD1 and WD2 on the end members in this way, even if there are differences in external dimensions due to the plate thickness of the blade SW or the presence or absence of a backing plate, it is easier to secure appropriate storage clearance in combination with the central member 21, thereby expanding the range of applicable blade SW.

[0052] As shown in Figures 3 and 4, the central member 21 has multiple holes (holes 81a, 82a, 81b, 82b) that define the mounting position of the base member 22, and multiple holes (holes 83a, 84a, 83b, 84b) that define the mounting position of the tip member 23, which are spaced apart in the longitudinal direction.

[0053] By selectively inserting the protrusions 92A and 92B of the base member 22 and the protrusions 93A and 93B of the tip member 23 according to the above correspondence, the length of the case body 2 (and consequently the blade storage case 1) can be adjusted in stages. In this embodiment, two-stage length adjustment is illustrated, but the number of stages may be increased to three or more by increasing the number of holes, etc.

[0054] Furthermore, the base member 22 and the tip member 23 are configured to be attached to the central member 21 in the opposite direction. For example, by making the shapes of the protrusions 92A, 92B, 93A, and 93B provided on the base member 22 and the tip member 23 the same, and configuring the shape and arrangement of the corresponding holes formed on the central member 21 to be symmetrical (or identical) with respect to the attachment direction, engagement and fixation can be achieved in the same way even when the attachment direction is reversed. This allows the relationship between the inside (body side) and outside of the case body 2 to be appropriately reversed depending on the dominant hand when carrying it or the attachment position, thereby improving ease of attachment and portability.

[0055] Furthermore, as shown in Figure 6, the tip member 23 is configured in a U-shape in cross-section by side wall portions 23A and 23B and a back wall portion 23C connecting these side wall portions 23A and 23B, and has an open end at the other end (tip side) in the longitudinal direction. This allows foreign matter (leaves, soil, gravel, etc.) adhering to the blade SW to fall out from the open end, making it less likely for foreign matter to accumulate inside the case body 2, and improving cleanability and maintainability.

[0056] The aforementioned open end at the tip not only improves the ease of cleaning the inside of the case but also contributes to the protection of the blade SW. Specifically, even if gravel or hard foreign matter gets into the inside of the case, it can be easily discharged to the outside through the open end, thus preventing these foreign matter from rubbing against and scratching the blade surface or sides when inserting or removing the blade SW. In other words, the open end provides a dual benefit: maintaining cleanliness inside the case and maintaining the surface quality of the stored item, the blade SW.

[0057] Next, the storage and removal of the blade SW will be explained with reference to Figure 7. As shown in Figure 7(A), the blade SW is inserted from the side through the vertically elongated opening 4 on the side and slides in a direction intersecting the longitudinal direction toward the internal space, thereby entering the stored state (Figure 7(B)). To remove the blade SW, as shown in Figure 7(C), the blade SW can be pulled out longitudinally from the opening 3. By separating the storage operation (insertion from the side) and the removal operation (pulling out from the short side) in this way, safety during carrying is ensured while ensuring ease of use for inserting and removing the blade.

[0058] Furthermore, with reference to Figure 8, the relationship between the magnetic attraction and holding by the magnet 5 and the movement restriction by the locking piece 6 will be explained. As shown in Figure 8(A), the blade SW is inserted from the side through the vertically elongated opening 4 on the side and introduced into the internal space. Next, when the blade SW is slid toward the internal space in a direction intersecting the longitudinal direction, as shown in Figure 8(B), the blade SW is attracted to the magnet 5 and held inside. Furthermore, if an external force or the like is applied to the blade SW while it is held, with a component in the direction toward the vertically elongated opening 4 on the side, as shown in Figure 8(C), the blade SW comes into contact with the locking piece 6, restricting its movement toward the vertically elongated opening 4 on the side, and preventing the blade SW from protruding (jumping out).

[0059] In this embodiment, an example is shown in which the case body 2 is composed of three members: a central member 21, a base member 22, and a tip member 23. However, for applications that do not require length adjustment or reversal of mounting direction, the case body 2 may be constructed as a single molded product. Even in this case, similar storage, holding, and operability can be obtained by providing a side vertical opening 4, an opening 3, and magnets 5 on the inner surface portion facing the side vertical opening 4. Note that the arrangement of the magnets 5 is not limited to the side wall portion 21A; they may be provided on the inner surface portion facing the side vertical opening 4, for example, on the inner surface of the side wall portion 21B. Also, if a part of the back wall portion 21C faces the side vertical opening 4 depending on the case shape, magnets 5 may be provided on that facing portion. [Explanation of symbols]
