Description

The present invention relates to a commodity suspending arm that suspends and supports a plurality of commodities in parallel along an axial direction, and a manufacturing method thereof.
Note that the product suspension arm of the present invention includes a product display card support arm which is used in parallel above the arm and which shows the product name, price, and the like.

For example, a product integrally including a metal base portion having a locking piece that can be locked to a bar material in a horizontal posture and a product hook (arm) made of a metal rod extending in a horizontal posture forward from the base portion. A support, and a corner end that can be inserted into an upward insertion square hole provided in the vicinity of the base end of the product hook of the product support, and a metal bar that can hold a card display of the product on the tip side. A merchandise display hook comprising a card support provided with a card arm has been proposed (see, for example, Patent Document 1).
However, when the product display hook is composed of a metal base part, a product hook made of a metal bar integral with the metal base part, and a card arm made of a metal bar, the weight of the product display hook as a whole In addition, the surface of each component is covered with chromium (Cr) plating, which is not preferable from the viewpoint of the environment.

In order to solve the above-mentioned problems and increase the safety against a collision from the lateral direction, it is made of a hard and highly elastic material (for example, ABS resin) and has both a large diameter portion and a small diameter portion. An inner / outer dual structure comprising a rod-shaped core member and a covering member made of a soft and elastically deformable material (for example, a soft resin such as silicon) covering the entire outside along the axial direction of the core member. A merchandise display hook having a merchandise support arm has been proposed (see, for example, Patent Document 2).
However, like the product support arm of the product display hook, in order to make a double structure consisting of a core member and a covering member made of different resin fat materials, for example, the core member is previously injection molded with a dedicated mold. Then, it is necessary to reset the core member in a cavity of a mold different from the above, and to injection-mold a covering member that covers the entire outside of the core member. Therefore, there is a problem that the cost required for the two types of molds is increased, and the manufacturing process and management thereof are complicated.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the present invention is made of a flexible resin, except for a distal end portion, a hollow portion along the axial direction, a slit between the hollow portion and the outer peripheral surface and along the axial direction, And with respect to the outer cylindrical body provided with a notch portion on the rear end side, a middle shaft body made of a metal bar is inserted into the hollow portion through the slit, and is bent together with the outer cylindrical body in the vicinity of the notch portion. It was created with the idea in mind.
That is, the product suspending arm of the present invention (Claim 1) is made of a resin having flexibility, and includes a hollow portion along the axial center portion excluding the tip portion, and the hollow portion and the outer peripheral surface. an outer cylindrical body having a slit, and a rear end of the run out the hollow portion from the outer peripheral surface, notch whole in a side view at the time of folding and is inclined obliquely upward with and along the axial direction between, It is made of a metal bar or tube, and is inserted into the hollow portion of the outer cylindrical body, and is inclined at the front end side and inclined in the axial direction, and located at the rear end side, in the vicinity of the cutout portion of the outer cylindrical body. And a middle shaft body having a bent portion bent at a right angle to the axial direction.

According to the commodity suspension arm, the following effects (1) to (3) are obtained.
(1) The middle shaft body made of a metal bar is inserted into the hollow portion of the outer cylinder body made of resin, and the middle shaft body is perpendicular to the outer cylinder body in the vicinity of the cutout portion of the outer cylinder body. Since it is bent, the product suspension arm is reduced in weight as a whole.
(2) Since the middle shaft body is inserted into the hollow portion of the outer cylindrical body, a relatively thin and safe metal plating film (for example, a silver plating film) or various types of the surface of the middle shaft body By coating a resin coating film exhibiting colors and colorful patterns, it is possible to easily create a gorgeous and fashionable atmosphere without causing environmental problems.
(3) As will be described in detail in the manufacturing method described later, the manufacturing cost is not required except for the mold for manufacturing the outer cylindrical body, and the insertion of the middle shaft body into the hollow portion of the outer cylindrical body or the outer cylindrical body At the same time, since the folding process can be performed manually, it is easy to provide at a low cost.

In addition, the resin which has the softness | flexibility which comprises the said outer cylinder body is a polypropylene (PP), for example, and has the softness | flexibility which can be bent at least.
The outer cylinder has an outer diameter of about 6 mm, and the hollow portion has an inner diameter of about 3.5 to 4 mm. However, the outer diameter and inner diameter may be appropriately set according to the size and weight of each product to be hung.
Further, the hollow portion is closed on the distal end surface side of the outer cylindrical body by the distal end surface which is a substantially semispherical curved surface, or has a vertical piece which will be described later.
Further, an inclined portion that is inclined in the same manner as the inclined portion of the central shaft body may be formed in advance on the distal end side of the outer cylindrical body.
Furthermore, the intermediate shaft body is exemplified by a bar made of spring steel, mild steel, stainless steel, or the like having an outer diameter of about 3.5 to 4.0 mm.
In addition, the “right-angled shape” means 90 degrees ± 2 degrees, but a practical range of 90 degrees to 90 degrees + 2 degrees is recommended.

The present invention also includes a product suspension arm (Claim 2) in which a cross section of the outer shape of the rear end portion, which is the rear end side of the bent portion of the outer cylindrical body, is noncircular.
According to this, in addition to the effects (1) to (3), the effect (4) is further obtained.
(4) When a hook that is locked to a bar member arranged in a horizontal posture along a side wall or a partition wall of a merchandise section is formed with a receiving hole that is upward and has a cross-section similar to the non-circular shape By inserting the rear end side of the product suspension arm into the receiving hole, the product suspension arm can be reliably prevented from inadvertently rotating along the horizontal (horizontal) direction, and the hook The posture extended to the front of the can be kept stable.
The non-circular shape includes a regular polygon that is a square or more, a deformed polygon that is a quadrilateral or more including a rectangle, an oval, an ellipse, a cross, a star, and a bowl.

Further, according to the present invention, the cutout portion of the outer cylindrical body connects a pair of inclined sides that are axisymmetric along the axial direction of the outer cylindrical body in a side view and the back sides of the pair of inclined sides. A product suspension arm (Claim 3) is also included, which is composed of a circular arc side or a horizontal side that makes contact with or close to the pair of inclined sides.
According to this, since the pair of inclined sides are in contact or close to each other between the back sides of the pair of inclined sides by the arc side or the horizontal side, the pair of inclined sides are almost in contact with each other. In addition, when the middle shaft body is bent at a right angle together with the outer cylinder body, it is possible to reliably prevent inadvertent deformation in which the vicinity of the back side of the pair of inclined sides that are in contact with each other protrudes outward and expands smoothly. It becomes a bent part of the outer shape. Therefore, the effects (1) and (2) can be obtained more remarkably.

In addition, according to the present invention, the front end side of the outer cylinder is an inclined portion inclined obliquely upward, or has a vertical piece having an insertion hole with a non-circular cross section on the inside. A lowering arm (Claim 4) is also included.
According to this, the product display card indicating the product name, price, etc. of the product can be attached to the inclined portion in a substantially vertical posture. On the other hand, the holder can be held in a non-rotatable manner by inserting a non-circular cross-section leg of the holder for holding the product display card into a non-circular cross-section insertion hole provided inside the vertical piece ( Effect (5)).
The vertical piece is provided with a vertical slit that reaches the insertion hole from the outer peripheral surface thereof, so that the legs of the holder can be closely fitted, and inadvertent rotation and withdrawal can be prevented.

  On the other hand, a method for manufacturing an arm for suspending a product according to the present invention (Claim 5) is made of a resin having flexibility, and includes a hollow portion along the central portion in the axial direction excluding the tip portion, the hollow portion and the outer periphery. A step of preparing an outer cylinder having a slit between the surface and the axial direction, and a cutout portion having a triangular shape in a side view reaching the hollow portion from the outer peripheral surface on the rear end side, and a metal rod A step of preparing a middle shaft body made of a material or a tube and insertable into the hollow portion of the outer cylindrical body, and a step of inserting the middle shaft body into the hollow portion of the outer cylindrical body through the slit of the outer cylindrical body And a step of bending the vicinity of the cutout portion of the outer cylindrical body, in which the middle shaft body is inserted into the hollow portion, together with the middle shaft body into a right angle.

According to the method for manufacturing a product suspension arm, the following effects (6) and (7) can be obtained.
(6) The product suspension arm can be reliably manufactured.
(7) In addition to a mold for injection molding the outer cylinder, for example, expensive equipment is unnecessary, and a step of inserting a middle shaft body into a hollow portion of the outer cylinder or a notch of the outer cylinder Since the step of bending the central shaft body at right angles near the portion can be performed manually, it is easy to manufacture the product suspension arm relatively inexpensively.
The step of preparing the outer cylinder includes producing a mold having a core that is the hollow portion, a notch on the rear end side, and a cavity that is similar to a non-circular outer shape. This is done by injecting molten resin into the cavity containing the child.
In addition, the outer cylinder may be subjected to the insertion step after an inclined portion with an axial direction inclined is provided on the tip side in advance.
Further, the step of bending the vicinity of the notch portion of the outer cylindrical body in which the middle shaft body is inserted into the hollow portion together with the middle shaft body at a right angle includes, for example, the notch portion of the outer cylinder body at a right-angled corner portion on a surface plate. This is done by pressing the vicinity and bending the rear end side of the middle shaft body.

Also good.

FIG. 3 is a vertical sectional view showing one use state of the commodity suspending arm 1.
As shown in FIG. 3, a bar member 15 made of a square steel pipe having a vertically-long rectangular cross section and a hollow portion 16 having a similar shape on the inside is previously placed in a horizontal posture and attached to a sales office (not shown). The bar member 15 has a hook 17 made of a hard synthetic resin integrally having a front side portion 18 and a rear side portion 19 and provided with a concave portion 20 that opens downwardly between the two. By locking the material 15 from above, it is set at a desired position in the front-rear (depth) direction of FIG. On the front side portion 18 and the rear side portion 19 of the hook 17. The receiving holes 21 that are open for each of the upper surfaces and have a regular hexagonal shape (non-circular shape) in plan view are individually formed in a vertical posture.

Small holes 22 communicating with the bottom surfaces of the front side portion 18 and the rear side portion 19 are individually formed near the center of the bottom surface of the receiving hole 21 of the hook 17. These small holes 22 are utilized, for example, for discharging dust in the receiving holes 21 to the outside.
As shown in FIG. 3, the rear end portion 6 of the product suspension arm 1 is inserted into the receiving hole 21 of the front side portion 18 of the hook 17 to support the arm 1 in a substantially horizontal posture. . In the horizontal straight portion 2s of the outer cylindrical body 2 of the arm 1, a plurality of products (not shown) are passed through through holes or bowl-shaped grooves (both not shown) provided in the upper part of each product. It can be suspended in parallel with each other.

Further, as shown in FIG. 3, above the product suspension arm 1, substantially the same structure as the above-described arm in which the rear end portion 6 is inserted into the receiving hole 21 of the rear side portion 19 of the hook 17. The product display card support arm 1a is supported in parallel.
On the inclined portion 5 side of the arm 1a, a product display card (not shown) indicating the product name and price of the product is attached in a substantially vertical posture.

Furthermore, only one receiving hole 21 may be provided on either the front side portion 18 or the rear end side 19 so that only the arm 1 or only the arm 1b described later can be supported.

  The product suspending arm 1 and the product display card supporting arm 1a have a rear end portion 6 whose vertical cross-sectional outer shape is a regular hexagon (non-circular shape). It is inserted into the receiving hole 21 which is similar and has a regular hexagonal shape. For this reason, for example, even when an inadvertent external force along a substantially horizontal direction is applied to one or both of the arms 1 and 1a, the bar member 15 and the front (tip) side in the direction perpendicular to the bar member 15 are provided. It is possible to stably hold the extended posture.

In addition, each of the arms 1 and 1a has a lightweight double structure in which the middle shaft body 10 made of a metal bar is inserted into the hollow portion 3 of the outer cylindrical body 2 made of the resin. By covering the surface of the body 10 with a relatively thin and safe metal plating film and a resin coating film with various colors and colorful patterns, it is easy to create a gorgeous and fashionable atmosphere without causing environmental problems. Has been. Further, as will be described later, equipment costs are not required except for the mold for manufacturing the outer cylinder 2, and the insertion of the middle shaft body 10 into the hollow portion 3 of the outer cylinder 2 and the middle shaft body 10 are not required. Since the bending process performed together with the outer cylinder 2 can be performed manually, it can be provided at a relatively low cost.
Therefore, the arms 1 and 1a surely have the effects (1) to (5).

Below, the manufacturing method of the said arm 1 for product suspension is demonstrated.
First, the process of preparing the said outer cylinder 2 was performed as follows.
As shown in FIG. 4 (A1), for example, a straight portion 2s made of the transparent or translucent resin and having a circular outer shape perpendicular to the axial direction is a regular hexagon. The outer cylindrical body 2a having the rear end portion 6 and the elongated hollow portion 3 extending in the axial direction except for the front end side is not shown in the center of the hemispherical front end surface 5r on the front end side. Injection molding was performed using a mold with which the gate communicated.
Next, as shown in FIG. 4 (A2), not shown between the hollow portion 3 excluding the tip side and the outer peripheral surface of the outer cylinder 2a and along the axial direction of the outer cylinder 2a. By inserting a blade, a slit 4 was formed along substantially the entire length except for the tip side.

The slit 4 may be formed simultaneously with the injection molding by changing the shape of the core in the cavity of the mold.
Next, as shown in FIG. 4 (A3), a notch 7 is formed by notching on the slit 4 side on the rear end 6 side of the linear portion 2s of the outer cylinder 2a, and the outer cylinder 2 Got. As shown in the enlarged view V1 of the one-dot chain line portion V in FIG. 4A3, the cutout portion 7 is a pair of inclined sides 7a, 7b that are line-symmetrical along the axial direction of the outer cylindrical body 2a in a side view. And a circular arc side 8 connected to the back side through a narrow opening.
As shown in the enlarged view V2 in FIG. 4A3, the rear side of the pair of inclined sides 7a and 7b may be a cutout portion 7 connected by a horizontal side 8f substantially parallel to the straight portion 2s.

In parallel, the step of preparing the middle shaft body 10 was performed as follows.
As shown in FIG. 4 (B1), a bar 10a similar to the hollow portion 3 of the outer cylinder 2 and made of spring steel was prepared in advance. The surface of the bar 10a is previously coated with a thin silver film or gold film by electrolytic plating via a base nickel film.
Next, the rod member 10a is bent so that the tip end side is slightly inclined with respect to the axial direction, and as shown in FIG. An intermediate shaft body 10 including the straight portion 11 was obtained.
Further, as shown in FIG. 4C, the middle shaft body 10 was inserted into the hollow portion 3 from the slit 4 of the outer cylindrical body 2. At this time, the inclined portion 5 inclined to the tip end side of the outer cylindrical body 2 was formed by being dragged by the inclined portion 12 of the central shaft body 10. In addition, the process which inserts the said center shaft body 10 in the hollow part 3 of the outer cylinder 2 is mainly performed manually.

Then, the straight portion 2s of the outer cylindrical body 2 in which the middle shaft body 10 is inserted into the hollow portion 3 is, for example, on the surface so that the notch portion 7 is located slightly outside the surface of the surface plate (not shown). As shown by the curved arrow in FIG. 4C, the rear end portion 6 of the outer cylindrical body 2 having the rear end side of the middle shaft body 10 at the center is bent downward by about 90 degrees.
If the fine notch (cut) having a V-shaped cross section is formed in advance on the outer peripheral surface of the middle shaft body 10 located in the vicinity of the notch 7, the bending process is facilitated.
As a result, as shown in FIG. 4D, a rear end portion 13 substantially perpendicular to the straight portion 11 is formed on the rear end side of the middle shaft body 10 via a substantially right-angled bent portion 14. It was done. At the same time, the cutout portion 7 of the outer cylindrical body 2 has a linear shape in which the pair of inclined sides 7a and 7b are in contact with each other or close to each other with the arc side 8 as a rotation center and inclined obliquely upward in a side view. A rear end portion 6 is formed on the rear end side of the cutout portion 7 so as to be substantially perpendicular to the linear portion 2s.

The product suspending arm 1 could be manufactured by sequentially performing the above steps.
According to the manufacturing method of the product suspension arm 1 as described above, the arm 1 having the effects (1) to (4) can be reliably manufactured (effect (6)). Moreover, in addition to the mold for injection molding the outer cylinder body 2, expensive equipment is not required, and the step of inserting the middle shaft body 10 into the hollow portion 3 of the outer cylinder body 2, the outer cylinder body, The process of bending the middle shaft body 10 in the right-angled manner in the vicinity of the two notches 7 can also be performed manually, so that the forearm 1 can be manufactured at a relatively low cost (effect (7)).
In addition, the bending process of the outer cylindrical body 2 and the middle shaft body 10 can be automatically performed using a manipulator or a multi-joint robot (not shown) as well as manually.
Further, the step of forming the notch 7 in the outer cylindrical body 2a can be performed by punching using a punch having a dedicated tip surface and a die having a hole for receiving the tip of the punch. .
