Description of the Related Art Conventionally, a lamp (for example, a straight tube fluorescent lamp) having a power supply lamp pin that protrudes in pairs in the longitudinal direction of a bulb from an end face of a base fixed to each end of a bulb is used as a fixture for a lighting fixture. There are many lamp socket devices that can be attached to the main body.

  As a lamp socket device of this type, a contact that is electrically connected by contact with a lamp pin and a rotor that is rotatably supported with respect to the socket case are provided in a socket case fixed to the fixture body. There is something to prepare. In the socket case, a case-side slit through which a pair of lamp pins passes is formed on the outer peripheral surface adjacent to the face facing the base, and a pair of faces introduced from the case-side slit on the face facing the base in the rotor. A rotor side slit into which the lamp pin is inserted is formed. Here, in a state where the rotor side slit communicates with the case side slit, the contacts are arranged on both sides in the width direction of the rotor side slit.

  In this lamp socket device, a pair of lamp pins are inserted into the rotor side slit in a state where the rotor side slit is communicated with the case side slit, and the lamp is rotated about the central axis of the base along the protruding direction of the lamp pin. As a result, each lamp pin comes into contact with each contact and is prevented from coming off from the rotor side slit, and the mounting of the lamp is completed. In addition, the lamp can be removed by rotating the lamp in the opposite direction to that at the time of mounting and removing the lamp pin from the rotor side slit through the case side slit.

  By the way, in the above-mentioned lamp socket device, a space for gripping and rotating the lamp when attaching and detaching the lamp is required around the lamp. Such structural members are often arranged close to the lamp, and there is a case where a sufficient space around the lamp is not secured and it is difficult to hold and rotate the lamp.

  On the other hand, the lamp socket device which can rotate a lamp | ramp without gripping a lamp | ramp is proposed (for example, refer patent document 1).

As shown in FIG. 10, the lamp socket device 1 described in Patent Document 1 is integrally coupled to the rotor 47 and has an operation arm 47 a that protrudes from the outer peripheral surface of the socket case 48. With this configuration, by operating the operating arm 47a and rotating the rotor 47, the lamp rotates together with the rotor-side slit 49 of the rotor 47, and the lamp can be attached and detached.

Further, as shown in FIG. 5A, the pair of contacts 8 are opposed to each other along the width direction of the guide slit 35 (the direction intersecting the longitudinal direction of the guide slit 35 in the rotation surface). ing.

  Therefore, in a state where the socket main body 9 is located at the free position, the movement of the pair of lamp pins 4 in the longitudinal direction of the guide slit 35 is not restricted, so that the pair of lamp pins 4 can be freely moved along the longitudinal direction of the guide slit 35. The lamp pin 4 can be inserted into and removed from the pin insertion hole 21 through the opening 39 and the introduction port 22. That is, the lamp 5 can be freely attached and detached. Since the dimension in the width direction of the guide slit 35 is set to be slightly larger than the diameter of the lamp pin 4, the pair of lamp pins 4 inserted into the pin insertion hole 21 are aligned in the longitudinal direction of the guide slit 35. Become.

  As described above, when the pair of lamp pins 4 is inserted into the pin insertion hole 21 as described above, the pair of lamp pins 4 is disposed between the pair of contacts 8 in the socket body 9 as described above. Since the pair of contacts 8 face each other along the width direction of the guide slit 35, the lamp pins 4 and the contacts 8 are not in contact with each other and are not electrically connected.

  On the other hand, in the state where the socket body 9 is in the restrained position, as shown in FIG. 5A, the pair of contacts 8 facing each other in the direction along the width direction of the guide slit 35 causes the rotation of the socket body 9. Accordingly, as shown in FIG. 5 (b), it rotates in the direction of arrow A (clockwise direction) and as shown in FIG. 5 (c), it faces in the direction along the longitudinal direction of the guide slit 35. Become.

  Therefore, when the socket body 9 is positioned at the restraining position with the pair of lamp pins 4 inserted into the guide slit 35 and the lamp 5 positioned at the fixed position, as shown in FIG. The pair of contacts 8 come into contact with the pair of lamp pins 4 to restrict the movement of the pair of lamp pins 4 in the longitudinal direction of the guide slit 35, and freely move the pair of lamp pins 4 along the longitudinal direction of the guide slit 35. In other words, the lamp 5 cannot be moved from the fixed position (the lamp 5 cannot be removed from the lamp socket device 1). In this state, since the pair of contacts 8 are in contact with the pair of lamp pins 4, the pair of contacts 8 and the pair of lamp pins 4 are electrically connected to each other. At this time, the contact 8 is positioned at a position corresponding to the guide slit 35 such that the pair of pin holding portions 8b face each other, and the pair of lamp pins 4 are sandwiched between the pair of pin holding portions 8b. In addition, since the contact 8 is a part of the conductive plate 12 formed using a plate made of a metal material having elasticity, the contact pressure between the lamp pin 4 and the contact 8 is ensured.

  When the socket body 9 is rotated from the free position to the restraint position, the contact 8 is moved from a position not in contact with the lamp pin 4 to a position in contact with the lamp pin 4. A force that rotates together with the socket body 9 is applied by 8. However, in this embodiment, since the lamp pin 4 is inserted through the guide slit 35 of the support portion 10, the rotation of the lamp 5 is restricted by the lamp pin 4 coming into contact with the inner side surface of the guide slit 35 in the width direction, The lamp 5 is prevented from rotating with the socket body 9.

  In the state where the socket body 9 is located at the restraining position, the guide slit 35 of the support portion 10 and the introduction port 22 of the socket body 9 do not overlap in the front-rear direction as shown in FIG. The introduction port 22 communicated with the insertion hole 21 is closed by the support portion 10. Therefore, in this state, since the lamp pin 4 cannot be inserted into and removed from the pin insertion hole 21 through the opening 39 and the introduction port 22, the lamp 5 can be freely attached and detached when the socket body 9 is positioned at the restraining position. It can not be done.

  As described above, in the lamp socket device 1 of the present embodiment, in a state where the socket main body 9 is located at the free position, the pair of contacts 8 face each other along the width direction of the guide slit 35 in the rotation plane, and the guide slit Since the movement of the pair of lamp pins 4 in the longitudinal direction of 35 is not restricted, the pair of lamp pins 4 can be inserted into the guide slit 35 from the opening 39 and the lamp 5 can be positioned at a fixed position with respect to the instrument body 7. In the state where the socket main body 9 is located at the restraining position, the pair of contacts 8 face each other along the longitudinal direction of the guide slit 35 in the rotation surface, so that the pair of lamps 5 located at the predetermined positions are opposed to each other. Since the pair of contacts 8 come into contact with each of the lamp pins 4 to restrict the movement of the pair of lamp pins 4 in the longitudinal direction of the guide slit 35, the lamp 5 can be fixed at the fixed position.

  Therefore, according to the lamp socket device 1 of the present embodiment, the lamp 5 can be attached and detached by rotating the socket body 9 between the free position and the restraining position. As a result, when the lamp 5 is attached or detached, the lamp 5 The lamp 5 which does not need to rotate itself and whose central axis of the base 3 is not on the same straight line can be mounted.

  Further, even when a space for holding and rotating the lamp 5 is not secured around the lamp 5, the attaching / detaching operation of the lamp 5 can be easily performed. Furthermore, in the conventional configuration shown in FIG. 10 in which the lamp 5 is attached / detached by moving the lamp 5 itself, when the lamp 5 becomes large, it becomes difficult to handle the lamp 5 and the workability of attaching / detaching the lamp 5 is deteriorated. In the lamp socket device 1 of the present embodiment, the lamp 5 can be easily attached and detached simply by moving the socket body 9 regardless of the size of the lamp 5, and therefore the workability of attaching and detaching the lamp 5 is deteriorated. There is no.

  In addition, since the socket body 9 only needs to be rotated when the lamp 5 is attached / detached, the area in which the socket body 9 moves when the lamp 5 is attached / detached becomes relatively narrow, and the area through which the socket body 9 passes around the socket body 9. Since it is not necessary to secure a large space, the fixture body 7 of the lighting fixture 6 can be downsized.

  Furthermore, according to the lamp socket device 1 of the present embodiment, the socket body 9 can be rotated by the operation lever 23, so that the lamp 5 can be easily attached and detached.

  By the way, in this embodiment, as shown in FIG. 1A, the operation lever 23 is a socket positioned at the opening edge of the guide slit 35 in the rotation plane in a state where the socket main body 9 is positioned at a free position. It is provided at the opening edge of the introduction port 22 in the inner body 11 which is a part of the main body 9.

  Therefore, according to the lamp socket device 1 of the present embodiment, the operation lever 23 can be used as a guide when the lamp pin 4 is inserted into the guide slit 35, so that the lamp 5 can be easily attached.

  Further, as shown in FIG. 1A, the side surface (right side surface in FIG. 1A) 23a of the operation lever 23 on the introduction port 22 side is continuous with the inner surface of the introduction port 22, and its normal direction. The direction orthogonal to the rotation plane (that is, the protruding direction of the operation lever 23 from the inner body 11) is the radial direction of the socket body 9. Therefore, as shown in FIG. 1A, the side surface 23a of the operation lever 23 is located on the guide slit 35 side when the socket main body 9 is located at the free position. While continuing to the side surface, the normal direction intersects the longitudinal direction of the guide slit 35.

  Therefore, the lamp pin 4 can be inserted into the guide slit 35 simply by moving the lamp pin 4 along the side surface 23a of the operation lever 23, so that the lamp 5 can be attached more easily.

  Further, as shown in FIG. 1A, the operation lever 23 moves the socket body 9 from the restraining position to the free position with respect to the guide slit 35 in a state where the socket body 9 is located at the free position. It protrudes from the inner body 11 of the socket body 9 so as to be located on the side in the rotating direction (counterclockwise direction side in FIG. 1A).

  Therefore, as shown in FIG. 2, when the lamp socket device 1 is attached to the fixture body 7, the side where the operation lever 23 is attached to and detached from the lamp 5 in the lighting fixture 6 (the side opposite to the fixture body 7 side). Placed in. Since the operation lever 23 is farthest from the fixture body 7 of the lighting fixture 6 when the socket body 9 is located at the free position, when the socket body 9 is rotated, Since it is possible to prevent the lamp 5 and the fixture body 7 from being hit, the lighting fixture 6 can be downsized.

  By the way, in this embodiment, the protrusions 42 are provided on both sides of the shaft protrusion 40 on the back surface of the front wall of the outer cover 30, and the recesses 43 into which the protrusions 42 are fitted are provided in portions corresponding to the protrusions 42 in the socket body 9. Yes. The concave portion 43 has a total of four locations, two locations facing each projection 42 when the socket body 9 is in a free position and two locations facing each projection 42 when the socket body 9 is in a restrained position. It is formed. Here, the front wall of the outer cover 30 has a flexible portion 44 that bends so as to move the protrusion 42 in the front-rear direction. Therefore, when the socket body 9 in the free position or the restraint position is rotated, the flexible portion 44 is bent and the protrusion 42 is retracted from the recess 43, and when the socket body 9 is rotated to the restraint position or the restraint position, the protrusion 42. Fits into the recess 43, and a click feeling is obtained when the socket body 9 rotates. Here, since the notch 25 formed in the inner cover 13 is also used as one recess 43, the recess 43 is actually formed in three places.

  Further, the lead-out hole 17 provided in the rear wall of the socket main body 9 is provided so as to penetrate along the rotation axis direction of the socket main body 9 (that is, the protruding direction of the lamp pin 4). 9 will be pulled out along the rotation axis. Therefore, even if the socket body 9 is rotated as shown by the arrow A between the free position shown in FIG. 6A and the restraint position shown in FIG. The passing area C1 can be kept relatively narrow. That is, it is not necessary to secure an extra space around the electric wire 14 when rotating the socket body 9.

  If the lamp socket apparatus 1 of this embodiment described above is used, not only the lighting fixture 6 corresponding to the straight tube-shaped lamp 5 as described above, but also a base along the protruding direction of the lamp pin 4 as shown in FIG. The lighting fixture 6 corresponding to the lamp 5 whose center axis of 3 is not on the same straight line can also be constituted.

  In the lamp 5 illustrated in FIG. 7, the protruding directions of the lamp pins 4 from the caps 3 are opposite to each other, and the pair of caps 3 are integrally coupled by a coupling piece 46. Although not shown here, the valve 2 is formed in a predetermined shape between the pair of caps 3. As an example of the valve 2, the two valves 2 whose one ends are connected in the vicinity of the middle portion of the both caps 3 are extended in a spiral shape centering on the connecting portion, and each end is connected to the cap 3. It can be of a fixed shape. The lighting fixture 6 corresponding to the lamp 5 includes a disk-shaped fixture body 7, and the lamp socket device 1 is disposed at a portion corresponding to each base 3 on one surface side of the fixture body 7.

  In this type of lamp 5, since the central axis of the base 3 is not collinear, the lamp 5 is attached to and detached from the lamp socket device 1 by rotating the lamp 5 around the central axis of the base 3 as in the conventional configuration. However, the lamp 5 can be attached and detached by using the lamp socket device 1 of the present embodiment. That is, as shown in FIG. 7A, with the socket body 9 in the free position, the lamp 5 is moved in the direction of arrow B, and the lamp pin 4 is passed through the opening 39 and the introduction port 22 with respect to the pin insertion hole 21. The lamp 5 is held and electrically connected by the lamp socket device 1 only by inserting and rotating the socket body 9 to the restraining position as indicated by the arrow A in FIG.

  As described above, if the lamp socket device 1 of the present embodiment is used, the lamp 5 can be attached and detached without moving the lamp 5 itself. Therefore, the lamp 5 whose center axis is not on the same straight line can be attached and detached. Is possible. Further, since the lamp 5 is not rotated, even when the central axis of the bulb 2 and the central axis of the base 3 are not on the same straight line as the lamp 5 in which the bulb 2 is formed in a spiral shape, It is not necessary to provide a space in a region through which the valve 2 passes when the valve 2 rotates, which leads to downsizing of the instrument body 7.

  Here, the movement range of the operation lever 23 when the socket main body 9 rotates between the free position and the restraining position is determined with the socket main body 9 or the support portion 10 in the direction along the length direction of the guide slit 35. If the lamp socket device 1 is in the overlapping range, that is, in the range in which the lamp socket device 1 overlaps the fixture main body 7 in the thickness direction of the fixture main body 7, the lamp socket device 1 is compared to the case where the movement range of the operation lever 23 is larger than the overlapping range. The area occupied by the instrument body 7 can be reduced, so that the instrument body 7 can be downsized.

  In the example shown in FIG. 7, the support portion 10 of the lamp socket device 1 of the present embodiment is provided with a lamp 5 having a pair of bases whose central axes along the protruding direction of the lamp pins 4 are not located on the same straight line. At this time, the socket body 9 is rotated so that the rotation direction when the socket body 9 is rotated from the free position to the restraint position is the direction in which the operation lever 23 is moved to the center side of the instrument body 7. The support unit 10 is rotatably supported.

  Therefore, when the socket body 9 is positioned from the free position to the restraint position, as shown in FIGS. 7A and 7B, the operation lever 23 moves to the center side of the instrument body 7. Since the area occupied by the lamp socket device 1 and the lamp 5 in the instrument body 7 can be reduced compared to the case where the instrument body 7 moves to the opposite side (that is, the outside), the area of the instrument body 7 of the luminaire 6 can be reduced. Miniaturization can be achieved.

  Or you may make it the socket main body 9 rotate in the reverse direction to the example shown to Fig.7 (a), (b). That is, the lamp socket device 1 has a fixture body 7 corresponding to a lamp 5 having a pair of bases whose support shafts 10 are not located on the same straight line as the central axis along the protruding direction of the lamp pin 4 as shown in FIG. The socket body 9 is rotated so that the operation lever 23 moves in the direction opposite to the center side of the instrument body 7 when the socket body 9 is rotated from the free position to the restraint position. May be.

  In this case, when the socket body 9 is positioned from the free position to the restraint position, the operation lever 23 moves to the side opposite to the center side of the instrument body 7 (that is, the outside), so FIGS. ), The lamp 5 and the operation lever 23 can be turned on when the socket body 9 is positioned at the restraining position and the lamp 5 can be lit as compared with the case where the operation lever 23 moves to the center side of the instrument body 7. Therefore, even when the life of the luminaire 6 reaches the end of its life, the socket body can be used by using the operation lever 23. 9 can be rotated, so that the lamp 5 can be easily attached and detached.

  By the way, the lamp socket device 1 shown in FIGS. 2 and 7 is configured so that the lamp 5 is attached to the instrument body 7 even when the socket body 9 is in a free position and the socket body 9 does not hold the lamp 5. A lamp holder for holding (temporarily holding) a fixed position is provided.

  The lamp holder is composed of a pair of elastic pieces 45 bent from an elastic plate. The elastic piece 45 has a holding piece 45 a formed in an arc shape curved along the side peripheral surface of the lamp 5, and the concave side of the holding piece 45 a is along a direction orthogonal to the length direction of the guide slit 35. Are provided on the instrument body 7 so as to face each other. Therefore, by positioning the lamp 5 between the pair of holding pieces 45a, the lamp 5 is held between the pair of holding pieces 45a, and the lamp 5 is held at the fixed position. That is, in this embodiment, the pair of holding pieces 45 a constitute a holding portion that holds the lamp 5 in a direction intersecting with the longitudinal direction of the guide slit 35.

  Further, the elastic piece 45 has a guide piece 45b that protrudes from an end portion (tip end portion) of the holding piece 45a opposite to the instrument main body 7 side. When the pair of elastic pieces 45 are provided on the instrument body 7 as described above, the guide pieces 45b are inclined so that the distance between the guide pieces 45b increases as the distance from the holding pieces 45a increases. Therefore, if the lamp 5 is positioned between the pair of guide pieces 45b and the lamp 5 is moved to the holding piece 45a side, the lamp 5 is guided to the holding piece 45a side by the guide piece 45b. That is, in this embodiment, the guide part which guides the lamp | ramp 5 to a holding | maintenance part is comprised by a pair of guide piece 45b.

  According to the lamp holder, the lamp 5 can be positioned at the fixed position even when the socket body 9 of the lamp socket device 1 is in the free position when the lamp 5 is attached or detached. When the socket body 9 is operated to rotate, it is not necessary to position the lamp 5 by hand, and the lamp 5 can be easily attached and detached. In particular, when removing the lamp 5 from the lamp socket device 1, it is not necessary to hold the lamp 5 by hand, so that the lamp 5 can be safely attached and detached even when the power to the contact 8 is not cut off. .

  The guide piece 45b can also be used when the lamp 5 is removed from the lamp holder. That is, if the guide pieces 45b are pressed in a direction away from each other, the holding pieces 45a bend and the interval between the holding pieces 45a is widened. Therefore, when the lamp 5 is removed from the lamp holder, the guide pieces 45b are separated from each other. If pressed, the lamp 5 can be easily removed.

  By the way, the lamp holder described above is formed such that the projecting dimension d from the instrument body 7 is larger than the projecting dimension D of the operation lever 23 from the instrument body 7 as shown in FIG. Therefore, since the lamp 5 is guided to be positioned at a fixed position with respect to the instrument body 7 by the guide portions (the pair of guide pieces 45b) for guiding the lamp 5 to the holding portions (the pair of holding pieces 45a), the lamp pin 4 is operated. The work along the side surface 23b of the lever 23 is facilitated, and the work of attaching the lamp 5 is further facilitated.

  By the way, in the example shown in FIG. 7, the elastic piece 45 is disposed in the vicinity of each support portion 10, and the elastic piece 45 holds the lamp 5 by contacting the base 3 of the lamp 5. Even the lamp 5 having the bulb 2 made of glass, which is difficult to ensure high strength due to the narrowing of the tube and the complicated shape, can hold the lamp 5 without applying a load to the bulb 2. .

  However, depending on the configuration of the fixture body 7 of the lighting fixture 6, it may be difficult to hold the lamp 5 with the base 3, or the lamp 5 may be more stably held with the bulb 2.

  In such a case, in consideration of the shape of the holding piece 45a and the elastic modulus of the material to be used, the lamp holder is designed so that when a force of 10 N is applied in the direction to remove the lamp 5 from the holding portion, What is necessary is just to comprise so that it may remove | deviate from a holding | maintenance part.

  According to such a lamp holder, since the force applied to the lamp 5 by the holding portion can be reduced, the lamp 5 can be prevented from being damaged. In particular, this is effective when the bulb 2 that is easily damaged in the lamp 5 is held by the holding portion.

  Further, in reducing the force applied to the lamp 5 by the holding portion, it is only necessary to reduce the thickness or the width of the holding piece 45a constituting the holding portion, thereby reducing the material cost of the lamp holder. In addition, a through hole may be provided in the holding piece 45a. In this case, since the light of the lamp 5 can be irradiated from the through hole of the holding piece 45a, the shadowed area of the holding piece 45a can be reduced and light emission can be performed. Efficiency can be improved.

  In the example shown in FIGS. 2 and 7, the pair of elastic pieces 45 constituting the lamp holder are fixed to the fixture body 7, but the elastic pieces 45 may be provided on the support portion 10. Further, when the elastic piece 45 is formed of a resin material, the support portion 10 and the elastic piece 45 may be integrally formed. Furthermore, in the present embodiment, the lamp holder is constituted by a pair of elastic pieces 45, but the lamp holder may be formed by integrally connecting a pair of elastic pieces 45.

  By the way, in the operation lever 23 shown in FIG. 1A, the normal direction of the tip surface 23b in the protruding direction is substantially orthogonal to the normal direction of the side surface 23a used as the guide surface of the lamp pin 4. 4 is moved along the side surface 23 a, one of the lamp pins 4 (the lamp pin 4 positioned far from the guide slit 35) is at the boundary between the tip surface 23 b and the side surface 23 a of the operation lever 23. There is a risk that the movement will be hindered.

  Therefore, as shown in FIG. 9A, the operation lever 23 is formed so that the angle between the normal direction of the distal end surface 23b of the operation lever 23 and the normal direction of the side surface 23a is an acute angle. May be adopted. In this way, when the lamp pin 4 is moved along the side surface 23a, it is possible to reduce one of the lamp pins 4 from being caught by the boundary portion. Therefore, the lamp 5 can be easily attached.

  When the tip surface 23b is also used as a guide surface in this way, the dimension H in the width direction (see FIG. 9A) of the tip of the operation lever 23 is the dimension h (see FIG. 9) between the pair of lamp pins 4. 9 (b)). In this way, when the lamp pin 4 is inserted into the guide slit 35 using the operation lever 23 as a guide, the tip of the operation lever 23 is not caught in the gap between the pair of lamp pins 4. It is possible to prevent the lamp 5 from being damaged by being caught on the operation lever 23 and applying an excessive load to the bulb 2 of the lamp 5. Moreover, since the lamp pin 4 is not caught by the operation lever 23, the guide performance when using the operation lever 23 as a guide can be improved.

  The configuration of the lamp socket device 1 described above is merely an example. For example, the function of preventing the conductive plate 12 from coming off from the inner body 11 is provided to the outer cover 30 and the inner cover 13 is omitted, or the outer cover 30 is removed. The lamp socket device 1 of the present invention can be realized in various configurations, such as being formed integrally with the fixture body 7, or the support portion 10 being constituted by two members that can be separated in the longitudinal direction of the guide slit 35.

  Then, according to the lighting fixture 6 provided with the lamp socket device 1 described above in the fixture main body 7, the lamp 5 can be attached to and detached from the fixture main body 7 without moving the lamp 5, so that the central axis of the base 3 Can be attached even if the lamps 5 are not on the same straight line, and the attaching / detaching work of the lamps 5 can be easily performed.
