Description

Technical Field

[0001] The present invention relates to a weight fixture attached to the base portion of a triangular cone.

Background Art

[0002] A triangular cone (Color Cone (registered trademark), pylon) is a conical safety device that is still commonly used at traffic control sites and construction sites. Also, to date, various types of triangular cones have been developed, such as those with a reflective sheet or those equipped with an LED, for the purpose of improving safety, visibility, convenience, etc.

[0003] For example, Patent Document 1 describes a weight tank with a bulb socket attached to it, which is attached to a color cone and used for night construction to prevent accidents at night. This weight tank with a bulb socket for a color cone has a weight tank provided on the color cone body, a bulb socket provided on the weight tank, and water is put into the weight tank so that it can be removed from the color cone.

[0004] On the other hand, Patent Document 2 describes a triangular cone and a method for installing the triangular cone for the purpose of enhancing stability during use. This method for installing the triangular cone fixes the triangular cone to the installation location by the magnetic force of a magnet attached to the bottom of the base of the triangular cone and the iron content contained in the paint applied to the installation location.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Although the technologies related to the triangular cones described in Patent Documents 1 and 2 both aim to improve convenience, especially in recent years, there has been a demand for improving the safety (stability) of triangular cones. For example, a triangular cone is a safety device that prevents the intrusion of vehicles and is lightweight and easy to carry, but in strong winds or the like, the triangular cone installed at the site may move or fall down.

[0007] Of course, adding weights to the triangular cone or making the triangular cone itself heavier will make it stable. However, when adding weights to the triangular cone, it is difficult to finely adjust the weight, such as when the weight is insufficient or too heavy. In addition, since a vehicle or the like may come into contact with the triangular cone installed at the site, if the triangular cone is made too heavy, there is a risk of causing significant damage to the contacting vehicle or the like. On the other hand, making the triangular cone itself heavier will cause problems in transportation and installation.

[0008] Therefore, an object of the present invention is to provide a weight attachment tool that does not impair convenience and improves safety (stability).

Means for Solving the Problems

[0009] The weight attachment tool according to the present invention is attached to the base portion of the triangular cone. And a gripping portion attached to approximately the central portion of one side of the base portion of the triangular cone having a substantially square shape and approximately the central portion of the other side facing the one side, respectively, and a support portion provided across between the gripping portions, the support portion being a support portion for supporting a weight disposed within the triangular cone, the weight being packed in a bag and having a deformable shape, and the support portion being provided such that the opening at the bottom of the triangular cone opens by more than half.

[0010] Thereby, the weight can be supported within the triangular cone, and a part of the weight protrudes from the gap of the opening at the bottom of the triangular cone and contacts the installation surface, increasing the friction coefficient.

[0011] Further, it is desirable that the support portion is provided so as to be positioned above the lower end of the base portion of the triangular cone.

[0012] Note that the gripping portion is slidable along one side and the other side of the base portion of the triangular cone, and it is desirable that the weight attachment member has a fixing portion for fixing the position of the gripping portion slid along one side and the other side with respect to the base portion.

Effect of the Invention

[0013] With such a configuration, the weight attachment member according to the present invention can support the weight inside the triangular cone, and a part of the weight protrudes from the gap of the opening at the bottom of the triangular cone and contacts the installation surface, increasing the friction coefficient, so that the stability of the triangular cone can be improved.

Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described in detail. However, the description of the constituent elements described below is an example (representative example) of the embodiments of the present invention, and the present invention is not limited to the following contents unless the gist thereof is changed.

[0016] [Weight Attachment Member] First, with reference to FIGS. 1 and 2, the configuration of a weight attachment member 1 according to an embodiment of the present invention will be described.

[0017] The triangular cone is generally conical with a hollow interior, having a circular opening at the bottom and a substantially square base portion. The weight attachment 1 is attached to the base portion 50 of the triangular cone 40 (see Fig. 2(A)), and has a gripping portion 10 (10A, 10B) and a support portion 20 (see Fig. 1).

[0018] The gripping portion 10A is attached to approximately the central portion of one side 52A of the base portion 50 of the triangular cone 40 which is substantially square. On the other hand, the gripping portion 10B is attached to approximately the central portion of the other side 52B of the base portion 50 (see Fig. 2(A)). In short, the gripping portions 10A and 10B are respectively attached to one side of the base portion 50 of the triangular cone 40 which is substantially square and the other side opposite to the said one side, and grip the base portion 50 so as to sandwich it from both side surfaces so that the weight attachment 1 does not come off from the triangular cone 40.

[0019] In addition, in the present embodiment, the gripping portion 10 is configured to be slidable along one side 52A and the other side 52B of the base portion 50 of the triangular cone 40. Further, the weight attachment 1 of the present embodiment has a fixing portion for fixing the position of the gripping portion 10 slid along one side 52A and the other side 52B of the base portion 50 with respect to the base portion 50.

[0020] On the other hand, the support portion 20 is a thin plate-like member provided across between the gripping portions 10A and 10B. In the present embodiment, the gripping portion 10 and the support portion 20 are formed by processing a thin steel plate, but there are no particular restrictions on the material of the gripping portion 10 and the support portion 20, the presence or absence of surface treatment, the presence or absence of painting, etc. For example, when aiming at weight reduction, it may be formed of plastic.

[0021] Further, since the support portion 20 is provided across between the gripping portions 10A and 10B, the length in its longitudinal direction is approximately the same as the length of one side of the base portion 50. Note that the length in the short direction is such that the opening 51 at the bottom of the triangular cone 40 opens by more than half (see Fig. 2(A)).

[0022] In Fig. 2(A), the weight attachment tool 1 is shown by a two-dot chain line for clarity. As shown in Fig. 2(A), the support portion 20 closes a part of the opening 51 at the bottom of the triangular cone 40. By closing a part of the opening 51 in this way, the support portion 20 supports the weight 60 so that the weight 60 disposed within the triangular cone 40 does not pop out from the opening 51.

[0023] Here, the weight 60 is deformable and packed in a bag. For example, the weight 60 is a sandbag filled with soil or the like in a sandbag, or a water bag filled with water or the like, but of course it is not limited to the examples shown.

[0024] With such a configuration, the weight attachment tool 1 can support the weight 60 while it is disposed within the triangular cone 40 (see Fig. 2(B)). Therefore, the weight of the triangular cone 40 can be increased, and it is possible to prevent the triangular cone 40 from moving or falling down due to strong wind or the like.

[0025] Here, when improving the stability of the triangular cone, since processing and work are easy, conventionally, weights were provided at the four corners of the base portion 50 of the triangular cone 40, or weights were placed on the base portion 50. However, for example, when weights are provided at the four corners of the base portion 50 of the triangular cone 40, since the weight is dispersed, there is a risk that one of the four corners may be lifted by wind or the like and the triangular cone may fall down or the triangular cone may move. On the other hand, since the weight attachment tool 1 according to the present embodiment has the weight 60 disposed within the triangular cone 40, the center of gravity is concentrated at the center of the triangular cone 40 (the center in the bottom view of the triangular cone 40 shown in Fig. 2(B)), and the stability can be improved as compared with the prior art.

[0026] Also, at this time, since the weight 60 is deformable and packed in a bag, taking the case where the weight 60 is a sandbag as an example, the weight of the sandbag can be arbitrarily changed (finely adjusted) depending on the amount of soil or the like packed in the sandbag, so that the delicate adjustment of the weight of the triangular cone 40 can be easily performed. Alternatively, if the weight of the triangular cone 40 is insufficient, sandbags divided into small portions can be further added into the triangular cone 40 to increase (finely adjust) the weight.

[0027] Furthermore, since the weight 60 is deformable and packed in a bag, a part of it protrudes from the opening 51 not blocked by the support portion 20 of the weight fixture 1 and contacts the installation surface at the place where the triangular cone 40 is installed. Therefore, the friction coefficient with respect to the grounding surface becomes high, and the triangular cone 40 becomes more stable.

[0028] In addition, in the present embodiment, the support portion 20 is provided so as to be located above the lower end of the base portion 50 of the triangular cone 40. Specifically, generally, protrusions 53 are provided at the four corners of the base portion 50 of the triangular cone 40 (see Fig. 2(A)). Due to the provision of these protrusions 53, a gap is generated between the base portion 50 and the installation surface. Therefore, for example, by making the thickness of the support portion 20 less than the gap, the support portion 20 can be provided so as to be located above the lower end of the base portion 50. Also, even in a configuration where the portions of the base portion 50 (one side 52A and the other side 52B of the base portion 50) where the gripping portions 10A and 10B are attached are recessed, the gripping portions 10A and 10B are engaged with the recessed portions, and the support portion 20 is located above the lower end of the base portion 50.

[0029] With such a configuration, it is possible to prevent the support portion 20 of the weight fixture 1 from contacting the installation surface and being damaged.

[0030] [Mounting procedure of weight fixture] Subsequently, referring further to Fig. 3, the mounting procedure of the weight fixture 1 according to the embodiment of the present invention will be described.

[0031] First, with the triangular cone 40 laid down, the operator puts the weight 60 into the triangular cone 40 through the opening 51 (see Fig. 3(A)).

[0032] Next, with the triangular cone 40 still laid down, the operator attaches the weight fixture 1 to the base portion 50 of the triangular cone 40. Since the gripping portions 10A and 10B of the weight fixture 1 are configured to be slidable along one side 52A and the other side 52B of the base portion 50 as described above, the operator can slide and attach the weight fixture 1 from above the base portion 50 (see Fig. 3(B)).

[0033] Note that the slid gripping portion 10 can be fixed to the base portion 50 by the fixing portion 30 (see the same figure). In this embodiment, the fixing portion 30 is a steel eye bolt, but it is not limited to this as long as the gripping portion 10 (weight fixture 1) can be firmly fixed to the base portion 50 of the triangular cone 40, and it may be a hexagonal bolt or a plastic part.

[0034] Finally, the operator raises the triangular cone 40 (see Fig. 3(C)). Note that when the operator removes the weight fixture 1 and the weight 60 from the triangular cone 40, the procedure is the reverse of the above-described one.

[0035] In this way, the weight fixture 1 can be easily attached to and removed from the base portion 50 of the triangular cone 40. Also, the size of the weight fixture 1 (such as the length and thickness of the gripping portion 10 and the support portion 20) can be appropriately designed according to the size of the base portion of the triangular cone, so it can be attached to any existing triangular cone regardless of its type and size.

[0036] In particular, since the weight fixture 1 according to this embodiment has a simple structure formed by processing a steel plate, the manufacturing cost, manufacturing time, etc. can be suppressed, and those of various sizes can be manufactured in small lots.

[0037] The configuration of the weight attachment tool 1 described as above is merely an example. For instance, instead of increasing the length of the support portion 20 in the short side direction, an opening portion may be provided in the support portion 20 so that the opening portion 51 at the bottom of the triangular cone 40 opens by more than half. In short, if the area of the support portion 20 is made too small, the weight 60 placed inside the triangular cone 40 will jump out from the opening portion 51. On the other hand, if the area of the support portion 20 is made too large, the contact portion of the weight 60 with the installation surface will also decrease. Therefore, the configuration of the weight attachment tool 1 is designed to achieve a balance between these two aspects.

[0038] Also, in this embodiment, the gripping portions 10A and 10B are respectively attached to the central portions of one side 52A and the other side 52B of the base portion 50 of the triangular cone 40 (see Fig. 2(A)). However, if the stability of the triangular cone is improved by the action and effect exerted by the weight attachment tool 1, the attachment position is not limited to this.

Industrial Applicability

[0039] The present invention is a weight attachment tool that does not impair convenience and improves safety (stability). It can be used anywhere where a triangular cone is utilized, so it is industrially useful.
