Description

  The present invention relates to a mounting structure for a surface lock, and more particularly to an improved technique for making the mounting height of the surface lock constant and preventing the displacement of the surface lock.

In recent years, glass doors have been frequently used due to the improvement in strength of glass materials. For example, when the full glass door is installed at an entrance of an office building or a store entrance, it is necessary to provide a locking device. Conventionally, in order to provide a locking device on this type of full-surface glass door, it has been common to provide a locking device on a hanging metal fitting, an upper collar, a lower collar, or a metal frame attached to the center.
However, if a metal frame portion is provided in order to provide a locking device, the design of the folded glass door may be lowered, and it is preferable that these metal frame portions are not provided.
In order to solve such a problem, the door lock of Patent Document 1 in which only the locking device is attached to the entire glass door using an attachment hole directly drilled in the door glass material has been proposed.
According to this door lock, it is possible to attach only the door lock to the open / close end of the full surface glass door without attaching a metal frame part for providing a locking device to the full surface glass door, without impairing the design of the full surface glass door, I was able to improve the appearance.

JP 2002-523660 Gazette

The surfaced lock attached to the glass door is attached by sandwiching the glass door from the front and back surfaces through a plurality of stud bolts penetrating the glass door. At this time, a liner made of a rubber plate is sandwiched between the back surface of the surface lock and the glass door surface for the purpose of preventing displacement.
However, in the case of a glass door, the material characteristic of the material having poor elasticity does not cause any biting or bending, and the rubber plate is crushed by the tightening of the stud bolt, exceeding the elastic limit. For this reason, the fastening state of each stud bolt is difficult to be uniform, and the mounting height of the face-locking on the glass door surface may not be constant. Further, since the rubber plate extends thinly beyond the elastic limit, an elastic restoring force cannot be obtained. As a result, the mounting structure is loosened, and the surfaced lock may be easily displaced.

  The present invention has been made in view of the above situation, and provides a mounting structure for a surface-mounted lock that can make the mounting height of the surface-mounted lock constant and prevent displacement of the surface-mounted lock, thereby stabilizing the mounting state. The purpose is to make it easier.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The attachment structure of the surface lock according to claim 1 of the present invention is an attachment structure of the surface lock 100 attached by sandwiching the glass door 11 from the front and back surfaces via a plurality of stud bolts 41 penetrating the glass door 11. There,
A resin plate 51 having a plurality of through-holes 53 and formed in substantially the same shape as the back surface shape of the surface-coated lock 100 and sandwiched between the glass door surface 55 and the back surface 57;
A rubber plate 67 that is fixed to the back surface 57 and that is disposed with a gap 69 on the inner periphery of the through-hole 53 and protrudes from the door contact surface 51a of the resin plate 51;
It is characterized by comprising.

  In this surface-locking mounting structure, when the stud bolt 41 is fastened, the rubber plate 67 protruding from the door contact surface 51a of the resin plate 51 is compressed, and the door contact surface 51a contacts the glass door surface 55. The conclusion is completed. At this time, the rubber plate 67 is compressed within the elastic limit, and the elastic restoring force is maintained. That is, the rubber plate 67 does not extend excessively thinly and does not exceed the elastic limit. Thereby, the resin plate 51 having a uniform thickness is sandwiched and the fixing is completed, the mounting height of the surface lock 100 is constant, and the displacement from the fastening position is prevented by the elastic restoring force of the rubber plate 67. .

The rubber plate 67 disposed in the region 75 having a large number of stud bolts 41 in the regions 73 and 75 in which the resin plate 51 is divided into substantially equal areas is disposed in the region 73 having a small number of stud bolts 41. It is characterized by being harder than the rubber plate 67.

  In this surface-attached lock mounting structure, in the resin plate 51, a region 75 having a large number of stud bolts 41 and a region 73 having a small number of stud bolts 41 are mixed. When the bolt 41 is tightened, the tightening force of the entire region 75 is larger than the tightening force of the entire region 73 having a small number of stud bolts 41. However, since the hard rubber plate 67b is sandwiched, the repulsive force of the rubber plate 67b is also increased. growing. As a result, the clamping force of the resin plate 51 is uniform in each of the regions 73 and 75.

In the regions 73 and 75 in which the resin plate is divided into substantially equal areas, the through holes 53 and the rubber plate 67 arranged in the region 75 having a large number of stud bolts 41 are regions 73 having a small number of stud bolts 41. The number of the through holes 53 and the number of the rubber plates 67 are larger than that of the rubber plate 67.

  In this surface-attached lock mounting structure, a region 75 having a large number of stud bolts 41 and a region 73 having a small number of stud bolts 41 are mixed, and the stud bolt 41 is tightened in a region 75 having a large number of stud bolts 41. Then, the tightening force of the entire region 75 is larger than the tightening force of the entire region 73 having a small number of stud bolts 41, but the repulsive force of the rubber plate 67 is increased due to the large number of rubber plates 67. As a result, the clamping force of the resin plate 51 is uniform in each of the regions 73 and 75.

The mounting structure of the surface-locking according to claim 4 is the mounting structure of the surface-locking according to any one of claims 1, 2, and 3,

  In this surface-attached lock mounting structure, more stud bolts 41 are provided in the arrangement region 75 of the cylinder lock 29 than in the other regions 73, and the fixing strength is increased. On the other hand, due to the arrangement of the hard rubber plate 67b and the increase in the number of rubber plates 67, the clamping force of the resin plate 51 in each of the regions 73 and 75 becomes uniform, and there is no difference in the mounting height.

  According to the surface-attached lock mounting structure of claim 1 according to the present invention, the resin plate that has a through hole and is sandwiched between the glass door surface and the surface-locked back surface, and is fixed to the surface-locked back surface. Since the rubber plate which is disposed in the through hole and protrudes from the door contact surface of the resin plate is provided, the mounting height of the surface lock can be made constant and the displacement of the surface lock can be prevented. As a result, it is possible to stabilize the mounting state that was not stable with the rubber liner alone.

  According to the mounting structure of the surface-coated lock according to claim 2, the rubber plate disposed in the region having a large number of stud bolts is harder than the rubber plate disposed in the region having a small number of stud bolts. In the region where the number of is large, the repulsive force of the rubber plate generated when the stud bolt is tightened becomes large, the holding force of the resin plate becomes uniform in each region, and the difference in the mounting height can be made difficult.

  According to the mounting structure of the surface-coated lock according to claim 3, the through holes and the rubber plate arranged in the region having a large number of stud bolts are more than the through holes and the rubber plate arranged in a region having a small number of stud bolts. Therefore, the repulsive force generated in the rubber plate when the stud bolt is tightened becomes equal, the holding force of the resin plate becomes uniform in each region, and the difference in mounting height can be made difficult.

  According to the mounting structure of the surface lock according to claim 4, since the cylinder lock is disposed in the region where the number of stud bolts is large, the surface lock mounting height is increased while increasing the fixing strength in the region where the cylinder lock is disposed. It is difficult to make a difference.

It is the perspective view which looked at the lock with face shown in 2 from the back side.
The attachment structure of the face-locking according to the present embodiment is suitable for use in, for example, a double-sided full-face glass door that is a glass opening / closing body. In addition, the mounting structure can be used for a single-open full-surface glass door, a double-open / single-open steel door, and the like. In the present embodiment, an example will be described in which the surface lock 100 shown in FIG. 1 having the mounting structure is provided on the double-sided full-face glass door 11 (11a, 11b).

  Glass panels 13 and 13 are provided on the left and right of the building opening, and the glass panels 13 and 13 are fixedly attached to an opening sash or the like. The pair of glass doors 11a and 11b described above are supported by hinges 15 and 15 so that the glass doors 11a and 11b can be opened and closed between the glass panels 13 and 13 through hinges 15 and 15, respectively. It is possible to restrict the opening to the outdoor side (the back of the paper in FIG. 1).

  As for glass doors 11a and 11b, for example, one glass door 11a is restricted from opening and closing, and only the other glass door 11b can be opened and closed. In this case, the opening / closing regulation of one glass door 11a can be performed by an opening / closing regulating means provided on the hinge 15 or the like. In this state, if the other glass door 11b is locked to the one glass door 11a, both the pair of glass doors 11a and 11b are in a locked state in which opening and closing is restricted. The surface-coated lock 100 according to the present embodiment works to lock the other glass door 11b to the one glass door 11a.

  A locked body 17 is attached to one of the glass doors 11a, and the locked body 17 protrudes from the face lock 100 and is a dead-bolt latch (hereinafter simply referred to as “latch”) 25 shown in FIG. The tip can be locked. In other words, in a state where one glass door 11a is fixed, the other glass door 11b has the latch 25 locked to the locked body 17 so that the indoor side (the front side of FIG. 1, the upper side of FIG. 2). ) Is restricted.

  The face lock 100 includes a lock case 21, lever handles 23A and 23B as opening / closing operation members, a latch 25, a thumb turn 27 and a cylinder lock 29 as locking / unlocking operation members arranged in parallel with the lever handles 23A and 23B. The trigger 31 (see FIG. 3) is provided outside. The lock case 21 includes an outdoor case 21a and an indoor case 21b. The outdoor case 21a and the indoor case 21b are attached with the door open / close end 32 of the glass door 11b being sandwiched.

  The surface lock 100 locks the glass door 11b by protruding the front end of a latch 25 that moves forward and backward from the lock case 21 fixed to the glass door 11b from the door opening / closing end 32 and locking it to the locked body 17. That is, the door opening restricted state is set. The lever handles 23 </ b> A and 23 </ b> B are pivotable with the shaft portion 35 penetrating the glass door 11 b and the lock case 21. Since the lever handle 23A, 23B is used for the surface lock 100, an operation force is applied from the rotation center (center of the shaft portion 35) as compared with the case where the opening / closing operation member is a ball grip handle or the like. A large distance to the action point is ensured, and a small rotational operation force can be easily and reliably input to the lock mechanism.

  In the mounting structure of the surface-coated lock 100 according to the present embodiment, a pair of lock boxes 37 and 39 are sandwiched from the front and back sides of the glass door 11b. The lock boxes 37 and 39 are covered with the indoor case 21b and the outdoor case 21a. A plurality of, in the present embodiment, four stud bolts 41 (41a, 41b, 41c), 42 are fixed to the indoor side lock box 39 by caulking or the like. The stud bolt 41 passes through the through hole 43 (see FIG. 5) of the glass door 11 b and is inserted into the outdoor case 21 a, and the female screw 47 on the front end face is screwed onto the fixing screw 45 inserted from the surface of the lock box 37. Is done. That is, the surface-coated lock 100 is attached by sandwiching the glass door 11b from the front and back surfaces via a plurality of stud bolts 41a, 41b, 41c penetrating the glass door 11b. In FIG. 3, reference numeral 42 denotes a positioning shaft for positioning the relative positions of the lock boxes 37 and 39.

  In the present embodiment, the base end portion of the stud bolt 41 is fixed to the indoor lock box 39. However, the stud bolt 41 may be fixed to the outdoor lock box 37 in the reverse configuration. In this case, the fixing screw 45 inserted into the lock box 39 on the indoor side is screwed onto the female screw 47 of the stud bolt 41.

4 is an exploded perspective view of FIG. 3, and FIG. 5 is a cross-sectional view of a main part in the mounting structure of the embodiment.
The face lock 100 is attached with a liner 51, which is a plate made of resin, for example, polypropylene, between the glass door 11b. The liner 51 has a plurality of, in this embodiment, four through-holes 53 and is formed in substantially the same shape as the back surface shape of the surface lock (inner side case 21 b), and the glass door surface 55 and the surface lock 100. And the back surface (the back surface 57 of the lock box 39).

  More precisely, as shown in FIG. 5, the back surface 57 of the lock box 39 is lower than the rear surface 59 of the indoor case 21b. That is, it is recessed. The liner 51 that is in close contact with the back surface 57 of the lock box 39 has the door contact surface 51a positioned flush with or slightly higher than the rear surface 59 of the indoor case 21b. In FIG. 4, reference numeral 61 denotes a connection hole for the locking / unlocking operation member (thumbturn 27, cylinder lock 29), 63 denotes a through hole in the shaft portion 35, and 65 denotes a through hole in the positioning shaft 42.

  A plurality of disk-shaped rubber plates 67 are fixed to the back surface 57 of the lock box 39 at positions corresponding to the through holes 53. The rubber plate 67 is disposed concentrically with the through-hole 53, so that the rubber plate 67 is disposed with a gap 69 (see FIG. 5) on the inner periphery of the through-hole 53. The gap 69 serves as an accommodation space when the rubber plate 67 is compressed and extended. Further, the rubber plate 67 protrudes from the door contact surface 51a of the liner 51 by a fastening allowance d. In a state where the fixing screw 45 is not tightened, a gap of a tightening allowance d is provided between the door contact surface 51a of the liner 51 and the glass door surface 55. This gap is not due to the completion of tightening of the fixing screw 45. The fastening allowance d is set by the amount of strain that falls within the elastic range of the rubber plate 67.

  In the present embodiment, the liner 51 has a large number of stud bolts 41 in a region divided into substantially equal areas, for example, left and right regions 73 and 75 divided into two by a dividing line 71 shown in FIG. Then, the rubber plates 67b, 67b arranged in the region 75 having three are harder than the rubber plates 67a, 67a arranged in the region where the number of stud bolts 41 is small, in this example, the region 73 where none is arranged. It has become. Note that. As a material of these rubber plates 67, EPDM (ethylene-propylene-diene rubber) is preferable.

  In the liner 51, the region 75 having a large number of stud bolts 41 and the region 73 having a small number of stud bolts 41 are mixed, and when the stud bolt 41 is tightened in the region 75 having a large number of stud bolts 41, The tightening force is larger than the tightening force of the entire region 73 having a small number of stud bolts 41, but the repulsive force of the rubber plates 67b and 67b is increased by sandwiching the hard rubber plates 67b and 67b. As a result, the clamping force of the liner 51 is uniform in each of the regions 73 and 75. This makes it difficult to produce a difference in mounting height between the regions 73 and 75.

  If all the rubber plates 67 have the same hardness, the rubber plate 67 disposed in the region 75 is compressed faster than the rubber plate 67 disposed in the region 73 and has the same thickness as the liner 51. . For this reason, an excessive tightening force is applied to the liner 51, and the region 75 side is excessively tightened due to the compression of the liner 51 itself or the deformation of the lock box 39, and there is a possibility that the liner 51 is attached low. Conversely, since the rubber plates 67 arranged in the region 73 have the same height and the same number, the fastening force by the stud bolt 41 is difficult to act, and the door contact surface 51a of the liner 51 is not pressed against the glass door surface 55. Or a state where they do not come into contact with each other, that is, there is a possibility that they are attached with high. In this configuration, by changing the hardness of the rubber plate 67, such a difference in mounting height between the regions 73 and 75 is made difficult to occur.

  In the present embodiment, the hardness of the rubber plate 67 is changed to correspond to the arrangement balance of the stud bolts 41. As another countermeasure, the studs in the regions 73 and 75 in which the liner 51 is divided into substantially equal areas are used. The structure which concerns on the modification which increases the through-hole 53 and the rubber plate 67 arrange | positioned in the area | region 75 with many bolts 41 from the through-hole 53 and rubber plate 67 arrange | positioned in the area | region 73 with few numbers of stud bolts 41. It is good.

  According to such a modification, the region 75 having a large number of stud bolts 41 and the region 73 having a small number of stud bolts 41 are mixed, and the stud bolt 41 is tightened in the region 75 having a large number of stud bolts 41. Then, the tightening force of the entire region 75 is larger than the tightening force of the entire region 73 having a small number of stud bolts 41, but the repulsive force of the rubber plate 67 is increased due to the large number of rubber plates 67. As a result, the clamping force of the liner 51 is uniform in each of the regions 73 and 75. This also makes it difficult to produce a difference in mounting height.

  Further, the cylinder lock 29 is disposed in the region 75 having a large number of stud bolts 41. More stud bolts 41 are provided in the arrangement area of the cylinder lock 29 than in the other areas 73, and the fixing strength is increased. On the other hand, due to the arrangement of the hard rubber plate 67b and the increase in the number of rubber plates, the clamping force of the liner 51 in each of the regions 73 and 75 becomes uniform, and there is no difference in the mounting height. Thereby, the difference in the surface-attached lock mounting height can be made difficult to occur while increasing the fixing strength in the arrangement region 75 of the cylinder lock 29.

  In the mounting structure of the surface lock 100 configured as described above, when the stud bolt 41 is fastened, the rubber plate 67 protruding from the door contact surface 51a of the liner 51 is compressed, and the door contact surface 51a is made of glass. The fastening is completed by contacting the door surface 55. At this time, the rubber plate 67 is compressed within the elastic limit, and the elastic restoring force is maintained. That is, the rubber plate 67 is thinly extended and does not exceed the elastic limit. As a result, the liner 51 having a uniform thickness is sandwiched and the fixing is completed, the mounting height of the surface lock 100 becomes constant, and the elastic restoring force of the rubber plate 67 prevents the displacement.

  Therefore, according to the mounting structure of the present embodiment, the liner 51 that has the through-hole 53 and is sandwiched between the glass door surface 55 and the surface-attached lock back surface 57, and is fixed to the surface-attached lock back surface 57 and the through-hole. Since the rubber plate 67 that is arranged at 53 and protrudes from the door contact surface 51a of the liner 51 is provided, the mounting height of the surface lock 100 can be made constant, and the displacement of the surface lock 100 can be prevented. As a result, it is possible to stabilize the attachment state of the face-attached lock 100 to the glass door 11 that has not been stabilized with a rubber liner alone.
