Description

The present invention relates to a ceiling hanging lamp (so-called pendant type lighting fixture) that is suspended from a ceiling or the like via a cord, and more particularly, to a ceiling hanging lamp of a type that holds three or more lamps .

  For example, when two or three ceiling hanging lights are installed close to each other for a table, in general, a plurality of power outlets such as a hanging ceiling body are provided on the ceiling, each with a hanging ceiling cap. This method can be used to hang multiple lamps by connecting multiple cords, or attach multiple lamp-type cord hangers to one power outlet and suspend multiple lamps from this cord hanger. Yes.

Patent Document 1 proposes a ceiling hanging lamp flange that allows a plurality of lamps to be moved to a desired position. The flange includes a plurality of attachment portions connected to the power supply extraction portion on the ceiling, and the position of the lamp can be changed by selecting the attachment portion.
Japanese Utility Model Publication No. 5-6531

  When installing a plurality of ceiling hanging lights, it is uneconomical to provide a plurality of power outlets on the ceiling as the wiring facilities increase. Moreover, in order to move each lamp to a desired position, a troublesome work such as attaching a cord hook or the like to the ceiling is required.

  Even when a multi-lamp type cord hanger is used, it is difficult to freely change the positional relationship between a plurality of lamps, and depending on the size of the lamps, the lamps may collide and break.

  In the flange described in Patent Document 1, the hanging position of the lamp relative to the flange itself is also fixed. For example, when three lamps are suspended, the relative positional relationship and height of the three lamps can be changed. It's not like that.

The present invention has been made to solve the above-described inconveniences, and even when a plurality of lamps are connected to a single power supply outlet provided on the ceiling, the positional relationship between the lamps can be freely changed. An object of the present invention is to provide a ceiling hanging lamp that can be used.

  In addition to the ceiling, for example, exposed beams that have been blown to the upper part of the atrium space, ridges that protrude into the air, shelf boards, etc. These parts are also included in the concept of “ceiling”.

In order to achieve the above object, in the ceiling hanging lamp of the present invention, three or more lamps are each suspended from a single power supply outlet provided on the ceiling via a flexible cord. In addition, each of the lamps is suspended in a state in which two or more support members formed by forming a cord hooking portion that can be hooked at an arbitrary position of the cord at both ends of a rod-shaped body having an appropriate length are independent of each other. It is characterized in that each lamp is held in a state in which individual heights and mutual intervals can be changed by being spanned between any two cords to be held.

  According to the present invention, the arrangement of the lamps can be freely changed by changing the position where the support is latched with respect to the cord. Even when multiple cords are bundled and taken out from one place, the distance between the lamps can be freely changed within the range of the length of the support tool, so that the lamps collide and break. Can also be prevented.

  In the above invention, each cord may be bundled in a flange that can be attached to the power supply outlet of the ceiling, and housed in a state where it can be taken in and out. According to this, the power supply extraction part provided in a ceiling is enough at one place, and can simplify a wiring installation. Furthermore, the height of the lamp can be freely changed by changing the length of the cord drawn out.

The support for the ceiling hanging lamp is provided with a cord hooking portion that can be hooked at an arbitrary position of the cord at both ends of a rod-shaped body having an appropriate length .

  The cord hooking portion preferably includes a ring provided at one end of the rod-like body and a hook extending from one portion of the ring toward the inside of the ring. According to this, the structure is simple and can be manufactured at low cost, and the engagement and disengagement of the cord is easy, and a simple and neat impression can be obtained in terms of design.

  If a cord retaining protrusion that bulges to the side of the hook is formed in the vicinity of the tip of the hook of the cord hooking portion, it is possible to prevent the cord from sliding off the ring by sliding toward the tip of the hook.

  According to the present invention, the arrangement of a plurality of lamps can be freely changed by simply using a plurality of supports having a simple structure. If the cord hooking portion of the support is made of a ring and a hook, the cord can be easily engaged and disengaged, and a simple and neat impression can be obtained in terms of design.

  Further, according to the present invention, even when a plurality of cords are bundled and taken out from one place, the distance between the lamps can be freely changed within the range of the length of the support. Therefore, it is possible to prevent the lamps from colliding with each other and breaking. Therefore, the power supply outlet provided on the ceiling is sufficient at one place, and the wiring facility can be simplified. However, the support of the present invention can be used for separate cords connected to a plurality of power supply outlets.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a ceiling hanging lamp of the present invention. In the illustrated ceiling hanging lamp 1, three lamps 2 are respectively suspended via three cords 3. Each of the three cords 3 is a resin-coated cord having general flexibility, and is housed in a bundled state in a flange 4 attached to a power outlet (not shown) on the ceiling. In the present invention, the shape and internal structure of the lamp 2 itself are not particularly limited.

  In the illustrated embodiment, the three lamps 2 are held in a horizontal row via the two support tools 5 that are hooked on the cord 3. The support 5 is provided with cord retaining portions 52 at both ends of a rod-like body 51 having appropriate rigidity and length, and the cross-sectional shape of the rod-like body 51 is arbitrary such as a circle or an appropriate polygon. .

  FIG. 2 is a partially enlarged view of the cord hooking portion 52. The cord hooking portion 52 includes a closed annular ring 53 that is integrally attached to one end of the rod-shaped body 51, and a hook 54 that extends from the end of the rod-shaped body 51 toward the inside of the ring 53. . The extension dimension of the hook 54 is longer than half of the inner diameter of the ring 53 and shorter than the inner diameter of the ring 53 by the thickness of the cord 3. Further, the size of the ring 53 and the thickness of the hook 54 are formed such that a gap slightly larger than the thickness of the cord 3 is formed between the inner edge of the ring 53 and the side surface of the hook 54. Further, on both side surfaces near the tip of the hook 54, small projections (cord retaining projections) 55 that project in a direction orthogonal to the ring 53 are formed.

  A part of the cord 3 is bent in a substantially U shape with respect to such a cord hooking portion 52, and the curved portion is inserted into the ring 53 from one side of the ring 53 and hooked on the opposite side of the hook 54. Since the tension due to the weight of the lamp 2 acts on the cord 3, the cord hooking portion 52 of the cord 3 is caused by friction between the curved cord 3 and the hook 54 and the ring 53, as shown by an imaginary line in FIG. 2. Hang in any position. The cord retaining protrusion 55 formed in the vicinity of the tip of the hook 54 prevents the cord 3 from being displaced toward the tip of the hook 54 and falling off the ring 53.

  In the ceiling hanging lamp 1 illustrated in FIG. 1, the first support 5 is bridged between the left lamp 2 and the central lamp 2, and the second support 5 is connected to the central lamp 2 and the right lamp 2. It spans between the lamps 2 and the three lamps 2 are held at almost equal intervals. The right end of the first support 5 and the left end of the second support 5 are overlapped and hooked at the same position of the cord 3 of the central lamp 2.

  The upper portions of the three cords 3 are bundled and inserted into a cord lead hole 41 provided at the center of the lower surface of the flange 4. A substantially cylindrical cord accommodating portion 42 is provided on the upper portion of the flange 4, and an excess portion of the cord 3 is accommodated while being wound around the cord 4. Now you can pull it out.

  FIGS. 3-4 shows the example which changed arrangement | positioning of the lamp 2 of the said ceiling hanging lamp 1. FIG. In these examples, three support tools 5 are used, each support tool 5 is spanned between two lamps 2, and the lamps 2 are arranged in a substantially triangular shape in plan view. As shown in FIG. 3, the interval between the lamps 2 increases when the inclination of the support 5 approaches the horizontal, and when the inclination of the support 5 increases as shown in FIG. 4, the interval between the lamps 2 decreases. If the pull-out length of the cord 3 that holds each lamp 2 is changed, the height relationship of the lamp 2 can be freely changed.

  The ceiling hanging lamp 1 can be suspended in a more varied form by further increasing the number of lamps 2 and cords 3 and hooking a large number of supporting tools 5 accordingly. About the support tool 5, you may prepare multiple types of things from which length differs.

  The cord hooking portion 52 of the support 5 is formed in a substantially U-shape or a substantially U-shape by opening the side of the ring 53, and the hook 54 is also slightly extended to make it like a three-pronged fork as a whole. It can also be made into a simple shape. Further, instead of the cord retaining protrusion 55 as described above, the cord retaining means can also be configured by expanding the tip of the hook 54 in the shape of a flat head or forming a protrusion or the like on the ring 53 side. can do.

  The ceiling hanging lamp of the present invention can be mainly applied to various lighting fixtures including indoor lighting of a house. In addition, the support of the present invention can be widely used as a holding means for the above-described lighting fixture, a ceiling-suspended small-sized facility similar to this, and a decorative article.
