Description

Rail type lighting fixtures}

The present invention relates to a rail-type lighting fixture that can be inserted into a track rail.

In general, long lighting fixtures in a long direction, such as straight lights and rail lights, may be installed using an auxiliary structure such as a separate frame or raceway. In the case of rail lighting, since the power supply conductor is attached to the rail due to the nature of the rail, the lighting rail can be attached or detached, so there is no need for separate wiring work, easy installation, and convenient movement.

Since the lighting is usually installed on the ceiling, in the case of a rail-type lighting fixture, if it is not firmly attached to the rail, it is separated from the rail and there is a problem that a person under the light may be injured or an object may be damaged.

In order to solve this problem, Republic of Korea Utility Model Registration No. 20-0492375 discloses a track lighting device. Republic of Korea Utility Model Registration No. 20-0492375 includes a track adapter that is inserted into and seated in a track rail that provides the external supply power in a state mounted on the ceiling and fixes a converter and a light source to the track rail, and the track adapter is provided on the left and right sides of one side of the adapter body having an elongated bar shape in the longitudinal direction, and includes a first electrode and a second electrode formed to be connected to the positive and negative electrodes of the externally supplied power source, respectively.

In addition, in order to keep the track adapter firmly coupled to the track rail, so that the connection between the anode and the first electrode is not separated, it is formed to be pushed outward through the elastic force of the buffer member and fitted into the groove provided on the track rail. A first protrusion and a second protrusion formed to be pushed out through the elastic force of a buffer member and fitted into a groove provided in a track rail so that the connection between the cathode and the second electrode is not separated, the first protrusion And in preparation for the case where the converter and the light source are separated from the track rail as the elastic force of the second protrusion is lost, the locking part and the locking part are rotated so that the fitting is ensured, so that the locking part is attached to the track rail. When retracted, it does not maintain a state coupled to the groove provided on the track rail, but includes a manipulation unit that maintains a state coupled to the groove provided on the track rail when the locking unit is rotated after being retracted into the track rail.

However, in the case of Republic of Korea Utility Model Registration No. 20-0492375, the structure is complicated by including a first protrusion, a second protrusion, a locking part, and a control part in order to maintain a state in which the track rail and the track adapter are firmly coupled to each other. Therefore, the cost required for production is high, and the assembly process of retracting and coupling the track adapter to the track rail is somewhat complicated.

In addition, the locking part 130 may further include a turning member 131 and a fitting member 132 in addition to the electrode moving member 133 provided on the upper side.

The turning member 131 has a circular plate shape provided at the bottom of the locking part 130, and the handle 131-1 is formed at the lower side, and the operator's fingers can be moved in one direction (D1) or in the other direction (D2). ) while rotating the handle 131-1 in one direction D1 or the other direction D2, the turning member 131 rotates the handle 131-1 in one direction D1 or the other direction D2. ) can be rotated 90 degrees.

As the fitting member 132 is rotated together as the turning member 131 rotates 90 degrees in one direction D1, a portion of both ends is drawn out of the housing 110 and the lower part of the track rail 10 It is inserted into the fitting space 11 provided in and fitted, and as the turning member 131 rotates 90 degrees in the other direction D2, both ends protruding to the outside of the housing 110 are rotated together. A portion may be drawn into the housing 110 after leaving the fitting space 11 .

The housing 110 is such that a portion of both ends of the fitting member 132 of each of the pair of locking parts 130 is drawn in or out while rotating 90 degrees in one direction D1 or the other direction D2. Corresponding to the position of the fitting member 132, a fitting member access through hole 113 having a portion opened may be formed.

In addition, a lighting fitting hole 116 is formed in the center of the lower surface of the housing 110 at a predetermined depth and partially opened, and through the lighting fitting hole 116, lighting can be coupled with the housing 110, , At this time, a lighting connection unit 140 for coupling the lighting to the lighting fitting hole 116 may be further included.

A rotation radius control groove 131-2 formed by partially recessing may be provided.

The rotation radius adjustment groove 131-2 limits the rotation angle of the locking unit 130 in one direction D1 or the other direction D2 to 90 degrees, and prevents rotation of the locking unit 130 according to rotation. can guide To this end, the rotation radius adjustment groove 131-2 includes a first groove portion 131-21 and a second groove portion 131-23.

The first groove part 131-21 may guide the rotation path of the locking part 130 in one direction D1 or the other direction D2, and the second groove part 131-23 may guide the rotation path in one direction D1 or the other direction D2. It is formed by being depressed deeper than the first groove part 131-21 and is connected to both ends of the first groove part 131-21 with slopes 131-22, and the locking part 130 is one-way (D1) or other The range of rotation angles in the direction D2 may be limited to 90 degrees.

In the lower part of the housing 110, a pair of protruding grooves 114 are formed so as to be inserted into the rotation radius adjusting groove 131-2 and made of a material having elasticity. When the rotation in one direction (D1) or the other direction (D2) is completed, the rotation of the locking part 130 can also be stopped by the protrusion groove 114 inserted into the second groove part 131-23. .

In particular, the second grooves 131-23 are formed by being recessed deeper than the first grooves 131-21, and when the rotation of the locking part 130 is completed, the protruding grooves 114 form the first grooves 131. -21) to the second groove 131-23, and by the hill 131-22 connecting the first groove 131-21 and the second groove 131-23 at an angle, 114) is fixed so that the locking part 130 does not rotate.

However, the operator places his hand on the handle 131-1 formed on the locking part 130 to push the locking part 130 upward while rotating the force in one direction (D1) or the other direction (D2). When generated, the protruding groove 114 is bent and climbs up the slope of the hill 131-22, and the locking part 130 can rotate in one direction D1 or the other direction D2. .

Referring back to FIGS. 1 to 4 , a process of coupling and separating the rail-type lighting fixture 100 according to an embodiment of the present invention to the track rail 10 will be described.

First, the process of coupling the rail-type lighting fixture 100 to the track rail 10 is as follows.

First, it is introduced into the track rail 10 through the lower open portion.

Second, the operator puts his/her finger on the handle 131-1 and then pushes the locking part 130 upward while inserting the protruding groove into any one of the pair of second grooves 131-23 ( 114) is separated from the first groove part 131-21 and rotated 90 degrees in the other direction D2 so that the fixed locking part 130 can rotate in one direction D1, and then the handle By turning (131-1) in one direction (D1), the locking part 130 is rotated 90 degrees in one direction (D1).

Thirdly, as the locking part 130 rotates 90 degrees in one direction D1, the fitting member 132 rotates 90 degrees in one direction D1 together, and parts of both ends of the fitting member 132 are fitted. It is drawn out of the housing 110 through the member access hole 113 and at the same time inserted into the fitting space 11 provided in the track rail 10 to be fitted.

At this time, as the locking part 130 rotates 90 degrees in one direction D1, the electrode moving member 133 rotates 90 degrees in one direction D1 like the fitting member 132, and the electrode moving member 133 rotates 90 degrees in one direction D1. While both ends of ) come into contact with each of the pair of electrodes 120, an external force is applied so that a portion of each of the electrodes 120 is drawn out through the electrode access hole 112 of the housing 110.

When an external force is applied to the electrode 120 and a portion is drawn out of the housing 110 through the electrode entry/exit hole 112, a portion of the electrode 120 drawn out of the housing 110 is connected to the electrode strip 20. They come into contact and are electrically connected, and power can be supplied to the lighting connected to the electrode 120 .

Fourth, when the rotation of the locking part 130 in one direction D1 is completed, the protruding groove 114 is one of the pair of second groove parts 131-23 in the first groove part 131-21. It is inserted into the other one and restricts additional rotation of the locking part 130 in one direction D1.

Fifthly, when the operator releases his/her hand from the handle 131-1, the force applied to the upper side of the locking part 130 disappears and the elastic force of the protruding groove 114 removes the locking part 130 ), the protruding groove 114 remains inserted into the second groove portion 131-23 as long as no force is applied.

At this time, a restoring force (F) for each of the electrodes 120 to return to the first state is generated by the restoring force (F) of each of the pair of electrodes 120, and the electrode moving member 133 Although an external force requiring rotation in the other direction D2 may be generated by the main force of the electrode 120, the restoring force F of the electrode 120 is offset by the elastic force of the protruding groove 114, thereby locking the lock. The part 130 does not rotate, and each of the electrodes 120 maintains an external force that pushes a portion of the electrode 120 out of the housing 110 by the electrode moving member 133 .

Next, the process of separating the rail-type lighting fixture 100 from the track rail 10 proceeds in reverse to the process of combining the rail-type lighting fixture 100 from the track rail 10, but the locking part The difference is only in that the 130 is rotated in the other direction D2, so the detailed description will be omitted.

According to the rail-type lighting fixture 100 of the present invention, the locking part 130 includes a handle 131-1, a turning member 131, a fitting member 132 and an electrode moving member 133, Electrical connection and coupling of the electrode 120 and coupling and separation to the track rail 10 can be simultaneously performed only by the operation of rotating the locking part 130, compared to the conventional rail-type lighting fixture 100. As the number is reduced, not only the manufacturing cost can be reduced, but the manufacturing process can be simplified, and the separation and coupling process of the rail-type lighting fixture 100 to the track rail 10 can be facilitated, so that the convenience of work can be improved.

The present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will come within the scope of the claims.

When one of the pair of locking parts 130 (hereinafter referred to as “first locking part 130a”) is rotated 90 degrees in one direction D1, a portion of each of the pair of electrodes 120 An electrode moving member 133 that generates an external force to be drawn out of the housing 110 and removes the external force applied to the electrode 120 when rotated in another direction D2 by 90 degrees,
The housing 110 is formed with a pair of electrode access holes 112 having a portion opened corresponding to the position of each electrode 120 so that a portion of each of the pair of electrodes 120 can be withdrawn,
Each of the pair of locking parts 130 has a handle 131-1 in which the operator's fingers are placed, and the operator's fingers rotate in one direction D1 or the other direction D2 while the handle 131-1 is formed. When 1) is rotated in one direction (D1) or the other direction (D2), 90 degrees in one direction (D1) or the other direction (D2) together with the handle (131-1) in one direction (D1) or the other direction (D2) Rotating turning member 131; and
As the turning member 131 rotates by 90 degrees in one direction D1, a portion of both ends is drawn out of the housing 110 as it rotates together, and the fitting space 11 provided at the bottom of the track rail 10 ), and as the turning member 131 rotates 90 degrees in the other direction D2, parts of both ends protruding to the outside of the housing 110 are inserted into the fitting space 11. It includes; a fitting member 132 that is drawn into the housing 110 out of the
The housing 110 is such that a portion of both ends of the fitting member 132 of each of the pair of locking parts 130 is drawn in or out while rotating 90 degrees in one direction D1 or the other direction D2. Corresponding to the position of the fitting member 132, a fitting member entrance through hole 113 is formed, a portion of which is opened,
On the upper side of the turning member 131 of each of the locking parts 130, a rotation radius adjustment groove 131-2 formed by partially recessing is provided,
The rotation radius control groove 131-2 is
a first groove portion 131-21 for guiding rotation of the locking portion 130 in one direction D1 or the other direction D2; and,
It is formed by being depressed deeper than the first groove part 131-21, and is connected to both ends of the first groove part 131-21 with slopes 131-22, and the locking part 130 is one-way (D1). Or a pair of second grooves (131-23) limiting the angular range of rotation in the other direction (D2) to 90 degrees;
In the lower part of the housing 110, a pair of protruding grooves 114 are formed so as to be inserted into the rotation radius adjusting groove 131-2 and made of a material having elasticity,
When the rotation of the locking part 130 in one direction D1 or the other direction D2 is completed, the locking part 130 is rotated by the protruding groove 114 inserted into the second groove part 131-23. rotation is stopped
A worker places his/her hand on the handle 131-1 formed on the locking part 130 to generate force to rotate the locking part 130 in one direction D1 or the other direction D2 while pushing the locking part 130 upward. When this is done, the protruding groove 114 is bent and climbs up the slope of the hill 131-22, and the locking part 130 can rotate in one direction (D1) or the other direction (D2) Rail-type lighting luminaire, characterized in that. delete delete
