【発明の属する技術分野】
本発明は、蛍光灯を取り付けるための蛍光灯ホルダに関する。
【0002】
【従来の技術】
従来、スーパーマーケットなどで使用されるショーケース等において、商品棚などの取付体に蛍光灯を取り付ける際には、蛍光灯ホルダが使用され、蛍光灯へ繋がる電線を固定するためには、蛍光灯ホルダの近くに電線用の保持具を別途設け、この保持具によって蛍光灯に沿って配線される電線を保持したり、テープ等で電線を仮留めするものが主流であった。
【0003】
そこで蛍光灯ホルダの取付体の表面に係止するためのバネ板を延設して、それを湾曲させ電線を保持できるようにした、蛍光灯ホルダと電線用の保持具を一体に設けた蛍光灯ホルダがある。(例えば、特許文献1参照)
【0004】
【特許文献1】
特開平9−251809号公報(段落0011、第3図)
【0005】
【発明が解決しようとしている課題】
しかしながら、文献1にあっては、保持部が蛍光灯ホルダと一体になったバネ板の一部であり、もっぱら蛍光灯ホルダを取付体との固定のために利用されている取付板を付勢するバネ板であって、その構造自体が強度を持たないものである。従ってバネ板の一部を使った保持部は、複数回の利用によって破損しやすいものである。
【0006】
本発明は、このような問題点に着目してなされたもので、把持リングを利用することで強度のある膨出部を形成して確実に電線を保持でき、複数回の電線の出し入れにも耐えられ、電線を配線するのに必要な保持具を別途設ける必要がない蛍光灯ホルダを提供することを目的とする。
【0007】
【課題を解決するための手段】
上記の目的を解決するために、本発明の蛍光灯ホルダは、把持リングに蛍光灯を把持して取り付けるようにした蛍光灯ホルダであって、取付首部と所定距離離れた位置の把持リングの所定範囲を外周に屈曲して蛍光灯と当接しない膨出部を形成し、該膨出部は蛍光灯を把持した際に棚板に向かって押し上げられる位置に設けると共に、膨出部の外周面を平滑な膨出面とし、該膨出部と取付首部との間で電線が保持できる保持スペースが形成されていることを特徴としている。
この特徴によれば、把持リングに膨出部を設けることで、電線の保持が可能になり、別途電線を固定する保持具を用意する必要がなく、部品点数を省略できるのでコストダウンが期待でき、また、蛍光灯ホルダの強度のある把持リングを利用したことで、強度のある膨出部を形成できるので、複数回の電線の出し入れによる膨出部の破損にも絶えることができるようになる。また、平滑な膨出面を形成したことで、膨出面上で電線を滑らせることができるので、容易に電線を挿入できるようになる。更に、蛍光灯を把持リングに把持した際に、加熱量の最も多い蛍光灯の端部が膨出部に当接しないので、電線への熱影響を少なくできるようになる。
【0010】
本発明の蛍光灯ホルダは、前記蛍光灯ホルダの取付首部が取付体に固定された際に、少なくとも前記取付首部、把持リング、膨出部、そして取付体の間で、電線を安定的に保持できる保持スペースを形成することが好ましい。
このようにすれば、蛍光灯ホルダを取付体に取り付けた状態において、取付首部、把持リング、膨出部、そして取付体との間に電線の保持スペースを形成して電線を保持できるようになり、更に蛍光灯によって電線を隠蔽することができるとともに、電線の脱落も防止できるようになる。
【0011】
本発明の蛍光灯ホルダは、棚板の下方にあり斜め下方を向く取付体に、前記膨出部が上方向を向くように前記蛍光灯ホルダを固定し、取付首部、把持リング、膨出部、取付体、そして棚板の間に電線の保持スペースを形成することが好ましい。
このようにすれば、蛍光灯ホルダを取付体に取り付けた状態において、取付首部、把持リング、膨出部、取付体、そして棚板との間に電線の保持スペースを形成して電線を保持できるようになり、把持リングに蛍光灯を取付時には、把持リングが外側に広がり、膨出部が棚板側に押圧されるので、膨出部と棚板との隙間が狭くなり、挿入した電線が抜けにくくなり、確実に電線を保持できるようになる。
【0012】
【発明の実施形態】
以下、本発明の実施例を図面に基づいて説明する。
【0013】
図1〜図2により本発明の実施形態に係る蛍光灯ホルダの取付体への取付構造の構成について説明する。
【0014】
先ず、図1に示すのは、本発明の実施例としての蛍光灯ホルダが取り付けられた、ショーケースの全体像を示す側断面図である。1はショーケース、2は商品を陳列する商品棚であり、この商品棚2の下面には、下段の商品を照らすための蛍光灯3が設けられており、この蛍光灯3を商品棚2の下面にある取付体4に把持するために蛍光灯ホルダ5が取り付けられている。
【0015】
図2(a)は、蛍光灯ホルダ5と、板状の取付体4の斜視図である。6は蛍光灯3を把持するための把持リング6であり、この把持リング6は、一部に開口部7を有する切欠円状をしている。把持リング6は弾性を有する合成樹脂等の材質で作られており、その開口部7から蛍光灯3を押し込むと、把持リング6は左右に開き、開口部7を蛍光灯3の太さまで広げ、蛍光灯3を把持リング6内に収めることができるようになっている。
【0016】
把持リング6の外周上部には、取付首部8が設けられており、取付首部8の根元の左右両側には、付勢手段としての弾性のあるバネ板9が把持リング6より突設しており、蛍光灯ホルダ5は、把持リング6と取付首部8、そしてバネ板9が一体構造となっている。
【0017】
把持リング6には、把持リング6の所定範囲を外周側に膨出させた膨出部11が設けられており、膨出面12と係止片13で形成されている。より詳しく説明すると、膨出部11は、把持リング6の一部を外方に突出するように屈曲して形成されており、このように膨出部11が、把持リング6の屈曲で形成されているため、膨出部11が蛍光灯3に当接しない部分が存在することになり、後述するように把持リング6が蛍光灯3に接する面積を少なくでき、長期間使用した際の蛍光灯3の発熱による把持リング6の歪みや変形を少なくすることができるようになる。また、10は、板状の取付体4に穿設された取付孔であり、この取付孔10は、この実施例では長円形状をした長孔である。
【0018】
更に、図2(b)に示すように膨出部11の膨出面12は、把持リング6の外周面が描く円形とほぼ同心円の曲線を描いて形成されている。
【0019】
また、取付首部8は、係止部14、係合部15、回転部16の三つの部位で構成されており、最上方に係止部14があり、その断面は取付体4に設けられた取付孔10にほぼ補形をなす長円形である。係合部15は、係止部14と回転部16の間に設けられており、その断面は四角形をなし、約90度の回転で取付孔10の内周に係合することができる。更に回転部16は、把持リング6の外周面に接合する部位であり、把持リング6に近づくに従い、その外形が小さくなっていく略錐体形状をしている。
【0020】
次に図3〜図5により本発明の実施形態に係る蛍光灯ホルダ5の取付構造の取付作業について説明する。
【0021】
図3は、本発明の使用例を示す斜視図であり、蛍光灯ホルダ5の取付首部8を、板状をした取付体4に穿設された長円形の取付孔10に一方向から挿入した際には、バネ板9は取付体4に当接し、その弾性により変形するので、取付首部8を根元まで挿入することができるようになる。この状態で取付孔10内に回転部16が位置するため、蛍光灯ホルダ5を容易に回転させることができるようになる。
【0022】
更に、蛍光灯ホルダ5を約90度回転させて手を離すと、バネ板9は、その弾性により取付体4を把持リング6から引き離すように押圧し、取付首部8は、挿入した方向とは、逆の方向に付勢されるようになり、取付孔10に係止部14が当接し、取付首部8は、取付孔10から抜けることがなく固定され、取付後は、係合部15が取付孔10の内周に係合し、蛍光灯ホルダ5の回転を制止することができる。
【0023】
図4(a)に示したのは、商品棚2に蛍光灯ホルダ5を取付時の側面図であり、2は商品棚を拡大した側断面図であり、2’は棚板であり、棚板2’の下面側には、取付体4が設けられており、この取付体4は、棚板2’に対して傾斜面を形成しており、取付体4の傾斜面には、長孔をした取付孔10が穿設されている。
【0024】
蛍光灯ホルダ5の取付首部8は、この取付体4の傾斜面に向かって、斜め下方より取付孔10に挿入され、その後、約90度回転させてから手を離すと取付首部8が取付孔10に固定される。
【0025】
図4(b)は、蛍光灯ホルダ5の取付後に電線17を保持するときの装置の側面図であり、蛍光灯ホルダ5の把持リング6の棚板2’に向く側には、膨出部11が形成されているので、取付首部8、把持リング6、膨出部11、取付体4そして棚板2’の間に保持スペース18を形成することができるようになる。
【0026】
電線17を保持スペース18に保持する際には、電線17を膨出面12の上を滑らせるようにして、棚板2’との間を通過させ保持スペース18内に挿入することができる。
【0027】
保持スペース18内に挿入された電線17は、把持リング6に形成された膨出部11の係止片13により、外側に向かって滑り落ちるのを防止できるので確実に保持スペース18内に保持されることになる。
【0028】
また、把持リング6は蛍光灯を出し入れしても破損しない強度を有しており、この強度のある把持リング6を利用して係止片13が形成されているため、電線17の挿入や取り外しを複数回行っても、係止片13が破損しずらくなり、長期間の使用に耐えることができるようになる。
【0029】
図5に示したのは、蛍光灯ホルダ5に蛍光灯3を把持させたときの側面図であり、開口部7より蛍光灯3が把持リング6内に挿入された際、蛍光灯3の外径は、把持リング6の内径より若干大きいので、把持リング6はその弾性により、外側に向かって広がることになり、膨出部11が棚板2’に向かって垂直方向に押し上げられ、膨出部11と棚板2’との隙間が狭くなり、保持スペース18内に保持された電線17が抜け落ちるのを防止でき、且つ電線17を蛍光灯3によって隠蔽することができるようになる。
【0030】
また、把持リング6の一部を外方に屈曲させて膨出部11を形成しているので、蛍光灯3の加熱量の最も多い端部を把持した際には、膨出部11が蛍光灯3より離間されているために把持リング6に伝わる熱量を減らすことができ、電線17への熱影響を少なくできるようになる。更に、膨出部11の内側と蛍光灯3の間に空間ができるので、例えば図5の二点鎖線で示すように、断熱性を有する電線17’を使用することで、膨出部11の内側に電線17’を保持させることができるようになる。
【0031】
以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。
【0032】
例えば、膨出部が図6に示した膨出部11’のような形状をしていても電線17の保持スペース18を形成することができるので、上記実施例と同様な効果を得ることができるようになる。
【0033】
【発明の効果】
本発明は以下の効果を奏する。
【0034】
(a)請求項1に記載の発明によれば、把持リングに膨出部を設けることで、電線の保持が可能になり、別途電線を固定する保持具を用意する必要がなく、部品点数を省略できるのでコストダウンが期待でき、また、蛍光灯ホルダの強度のある把持リングを利用したことで、強度のある膨出部を形成できるので、複数回の電線の出し入れによる膨出部の破損にも絶えることができるようになる。また、平滑な膨出面を形成したことで、膨出面上で電線を滑らせることができるので、容易に電線を挿入できるようになる。更に、蛍光灯を把持リングに把持した際に、加熱量の最も多い蛍光灯の端部が膨出部に当接しないので、電線への熱影響を少なくできるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a fluorescent lamp holder for mounting a fluorescent lamp.
[0002]
[Prior art]
Conventionally, in a showcase used in a supermarket or the like, a fluorescent lamp holder is used when a fluorescent lamp is attached to an attachment such as a product shelf, and a fluorescent lamp holder is used to fix an electric wire connected to the fluorescent lamp. In the mainstream, a holder for the electric wire is separately provided near and the electric wire wired along the fluorescent lamp is held by the holder, or the electric wire is temporarily fixed with a tape or the like.
[0003]
Therefore, a fluorescent lamp holder and an electric wire holder that are integrated with a fluorescent lamp holder are provided by extending a spring plate for locking to the surface of the fluorescent lamp holder mounting body, and bending the spring plate to hold the electric wire. There is a light holder. (For example, see Patent Document 1)
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 9-251809 (paragraph 0011, FIG. 3)
[0005]
[Problems to be solved by the invention]
However, in the literature 1, the holding part is a part of the spring plate integrated with the fluorescent lamp holder, and the mounting plate used exclusively for fixing the fluorescent lamp holder to the mounting body is energized. And the structure itself has no strength. Therefore, the holding part using a part of the spring plate is easily damaged by a plurality of uses.
[0006]
The present invention has been made paying attention to such problems, and by using a grip ring, a strong bulge can be formed to securely hold an electric wire, and can be inserted and removed multiple times. It is an object of the present invention to provide a fluorescent lamp holder that can withstand and does not require a separate holder necessary for wiring an electric wire.
[0007]
[Means for Solving the Problems]
In order to solve the above object, a fluorescent lamp holder of the present invention is a fluorescent lamp holder to attach to grip the fluorescent lamp retaining ring, predetermined mounting neck and the retaining ring of a position at a predetermined distance The bulging portion is bent to the outer periphery to form a bulging portion that does not contact the fluorescent lamp, and the bulging portion is provided at a position that is pushed up toward the shelf when the fluorescent lamp is gripped, and the outer peripheral surface of the bulging portion Is a smooth bulging surface, and a holding space capable of holding the electric wire is formed between the bulging portion and the mounting neck portion .
According to this feature, it is possible to hold the electric wire by providing the bulging part on the grip ring, and it is not necessary to prepare a holder for fixing the electric wire separately, and the number of parts can be omitted, so a cost reduction can be expected. In addition, since a strong bulging portion can be formed by using the strong grip ring of the fluorescent lamp holder, it is possible to eliminate damage to the bulging portion due to multiple insertions and withdrawals of the electric wire. . Further, since the smooth bulge surface is formed, the electric wire can be slid on the bulge surface, so that the electric wire can be easily inserted. Furthermore, when the fluorescent lamp is gripped by the grip ring, the end of the fluorescent lamp with the largest heating amount does not come into contact with the bulging portion, so that the thermal influence on the electric wire can be reduced.
[0010]
In the fluorescent lamp holder of the present invention, when the mounting neck portion of the fluorescent lamp holder is fixed to the mounting body, the electric wire is stably held at least between the mounting neck section, the grip ring, the bulging section, and the mounting body. It is preferable to form a holding space that can be formed.
In this way, in a state where the fluorescent lamp holder is attached to the attachment body, a wire holding space can be formed between the attachment neck portion, the grip ring, the bulging portion, and the attachment body to hold the wire. Furthermore, the electric wire can be concealed by a fluorescent lamp, and the electric wire can be prevented from falling off.
[0011]
The fluorescent lamp holder of the present invention fixes the fluorescent lamp holder to an attachment body that is below the shelf and faces obliquely downward so that the bulging portion faces upward, and has a mounting neck portion, a grip ring, and a bulging portion It is preferable to form an electric wire holding space between the mounting body and the shelf board.
In this way, in a state where the fluorescent lamp holder is attached to the attachment body, the electric wire can be held by forming a holding space for the electric wire between the attachment neck, the grip ring, the bulging portion, the attachment body, and the shelf board. When attaching a fluorescent lamp to the grip ring, the grip ring spreads outward and the bulge is pressed toward the shelf, so the gap between the bulge and the shelf is narrowed, and the inserted wire It becomes difficult to pull out and the electric wire can be securely held.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0013]
The structure of the attachment structure to the attachment body of the fluorescent lamp holder which concerns on embodiment of this invention with FIGS. 1-2 is demonstrated.
[0014]
First, FIG. 1 is a side sectional view showing an entire image of a showcase to which a fluorescent lamp holder as an embodiment of the present invention is attached. 1 is a showcase, 2 is a product shelf for displaying products, and a fluorescent lamp 3 for illuminating a lower product is provided on the lower surface of the product shelf 2. A fluorescent lamp holder 5 is attached to be gripped by the attachment body 4 on the lower surface.
[0015]
FIG. 2A is a perspective view of the fluorescent lamp holder 5 and the plate-like attachment body 4. Reference numeral 6 denotes a grip ring 6 for gripping the fluorescent lamp 3, and the grip ring 6 has a cutout circular shape having an opening 7 in a part thereof. The grip ring 6 is made of a material such as a synthetic resin having elasticity. When the fluorescent lamp 3 is pushed through the opening 7, the grip ring 6 opens to the left and right, and the opening 7 is expanded to the thickness of the fluorescent lamp 3, The fluorescent lamp 3 can be accommodated in the grip ring 6.
[0016]
A mounting neck portion 8 is provided on the outer peripheral upper portion of the grip ring 6, and elastic spring plates 9 as urging means protrude from the grip ring 6 on both the left and right sides of the base of the mount neck portion 8. In the fluorescent lamp holder 5, the grip ring 6, the attachment neck 8, and the spring plate 9 are integrated.
[0017]
The grip ring 6 is provided with a bulging portion 11 that bulges a predetermined range of the grip ring 6 toward the outer peripheral side, and is formed by a bulging surface 12 and a locking piece 13. More specifically, the bulging portion 11 is formed by bending a part of the grip ring 6 so as to protrude outward, and thus the bulging portion 11 is formed by bending the grip ring 6. Therefore, there is a portion where the bulging portion 11 does not come into contact with the fluorescent lamp 3, and as will be described later, the area where the grip ring 6 contacts the fluorescent lamp 3 can be reduced, and the fluorescent lamp when used for a long period of time can be reduced. The distortion and deformation of the grip ring 6 due to the heat generation of 3 can be reduced. Reference numeral 10 denotes an attachment hole formed in the plate-like attachment body 4, and the attachment hole 10 is an elongated hole having an oval shape in this embodiment.
[0018]
Further, as shown in FIG. 2B, the bulging surface 12 of the bulging portion 11 is formed by drawing a curve that is substantially concentric with a circle drawn by the outer peripheral surface of the grip ring 6.
[0019]
Further, the mounting neck portion 8 is composed of three portions, that is, a locking portion 14, an engaging portion 15, and a rotating portion 16. The locking neck portion 14 is at the uppermost portion, and the cross section thereof is provided on the mounting body 4. The mounting hole 10 has an oval shape that is substantially complementary. The engaging portion 15 is provided between the locking portion 14 and the rotating portion 16, and has a rectangular cross section, and can be engaged with the inner periphery of the mounting hole 10 by rotating about 90 degrees. Further, the rotating portion 16 is a portion joined to the outer peripheral surface of the grip ring 6 and has a substantially pyramid shape whose outer shape becomes smaller as the grip ring 6 is approached.
[0020]
Next, the attachment work of the attachment structure of the fluorescent lamp holder 5 according to the embodiment of the present invention will be described with reference to FIGS.
[0021]
FIG. 3 is a perspective view showing an example of use of the present invention, in which the attachment neck 8 of the fluorescent lamp holder 5 is inserted from one direction into an oval attachment hole 10 drilled in a plate-like attachment body 4. In this case, the spring plate 9 abuts on the attachment body 4 and is deformed by its elasticity, so that the attachment neck portion 8 can be inserted to the root. In this state, the rotating part 16 is positioned in the mounting hole 10, so that the fluorescent lamp holder 5 can be easily rotated.
[0022]
Further, when the fluorescent lamp holder 5 is rotated about 90 degrees and the hand is released, the spring plate 9 presses the attachment body 4 away from the grip ring 6 due to its elasticity, and the attachment neck portion 8 is different from the inserted direction. The locking portion 14 comes into contact with the mounting hole 10, and the mounting neck 8 is fixed without coming out of the mounting hole 10. After the mounting, the engaging portion 15 is The rotation of the fluorescent lamp holder 5 can be stopped by engaging with the inner periphery of the mounting hole 10.
[0023]

The mounting body 4 forms an inclined surface with respect to the shelf plate 2 ′, and a long hole is formed in the inclined surface of the mounting body 4. A mounting hole 10 is formed.
[0024]
The mounting neck portion 8 of the fluorescent lamp holder 5 is inserted into the mounting hole 10 obliquely from below toward the inclined surface of the mounting body 4, and then rotated about 90 degrees and then released, the mounting neck portion 8 becomes the mounting hole. 10 is fixed.
[0025]
FIG. 4B is a side view of the apparatus when the electric wire 17 is held after the fluorescent lamp holder 5 is attached. On the side facing the shelf 2 ′ of the grip ring 6 of the fluorescent lamp holder 5, 11 is formed, a holding space 18 can be formed between the mounting neck 8, the grip ring 6, the bulging portion 11, the mounting body 4, and the shelf 2 '.
[0026]
When the electric wire 17 is held in the holding space 18, the electric wire 17 can be inserted into the holding space 18 through the shelf 2 ′ so as to slide on the bulging surface 12.
[0027]
The electric wire 17 inserted into the holding space 18 can be prevented from slipping outward by the locking piece 13 of the bulging portion 11 formed in the grip ring 6, so that the electric wire 17 is reliably held in the holding space 18. It will be.
[0028]
In addition, the grip ring 6 has a strength that does not break even when the fluorescent lamp is inserted and removed, and the locking piece 13 is formed by using the grip ring 6 having this strength. Even if the operation is performed a plurality of times, the locking piece 13 is hard to break, and can be used for a long time.
[0029]
FIG. 5 is a side view of the fluorescent lamp holder 5 when the fluorescent lamp 3 is gripped. When the fluorescent lamp 3 is inserted into the grip ring 6 through the opening 7, Since the diameter is slightly larger than the inner diameter of the grip ring 6, the grip ring 6 expands outward due to its elasticity, and the bulging portion 11 is pushed up in the vertical direction toward the shelf plate 2 ′ to bulge out. The gap between the portion 11 and the shelf board 2 ′ is narrowed, so that the electric wire 17 held in the holding space 18 can be prevented from falling off, and the electric wire 17 can be concealed by the fluorescent lamp 3.
[0030]
In addition, since the bulging portion 11 is formed by bending a part of the grip ring 6 outward, when the end portion of the fluorescent lamp 3 having the largest heating amount is gripped, the bulging portion 11 is fluorescent. Since it is separated from the lamp 3, the amount of heat transmitted to the grip ring 6 can be reduced, and the thermal influence on the electric wire 17 can be reduced. Furthermore, since a space is created between the inside of the bulging portion 11 and the fluorescent lamp 3, for example, as shown by a two-dot chain line in FIG. The electric wire 17 ′ can be held inside.
[0031]
