Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a band switch arranged at the closing edge of a closing object, such as a swinging door, a sliding door, a revolving door or a container lid, which can be moved to close the lid. The present invention relates to a main body and an elastic switch.

As a prior art elastic switch, one described in West German Patent Application No. 2,719,438 is known. In this elastic switch, a pair of band contacts are fixed to an elastic insulating member to form a □ switch body, and after completion, this switch body is drawn into the elastic nozzle of the elastic switch. The disadvantage of this structure is that
The problem is that the band contact is too exposed to the external environment until it is placed in the hollow chamber of the elastic housing. In this case, the pair of band contacts are easily damaged while being transported to the place of use and when being drawn into the hollow part of the elastic housing of the elastic switch. Furthermore, in the elastic switch according to the prior art, even when a lateral force is applied to the elastic switch, the pair of diajunction points do not necessarily come into electrical contact without any problem. □ A resilient switch is disclosed in which the points are pulled close to their point of attachment. According to this configuration, the pair of band contacts are drawn into the elastic housing of the elastic switch that is attached to the door that opens and closes, similar to the elastic switcher described above.

Therefore, the earlier West German Application No. 2,719,43
There is a risk that the same damage will occur as in the case of the safety device □ described in Publication No. 8 □.

Above □ U.S. Patent No. 4. In the island elastic switch described in No. 1'15,952, the outer ends of both webs of an elastic housing arranged in a V-shape are integrally connected to an outwardly convex semicircular member. , as the elastic housing is another drawback. That is, there is neither a transverse connecting member nor a lip that would be provided on this member between the ends of the two webs that face each other at the most distant position. When the semicircular member is bent to protrude toward the pair of band contacts due to contact with an obstacle, the webs arranged in a figure 7 configuration are initially pushed to spread out, so that immediately The closing action of the switch body does not occur.In conventional elastic switches, when the switch operation force is relatively large or the switch operation stroke is very large, the elastic nozzle of the elastic switch is considerably large. Only after deformation does the closing action of the switch body occur.Furthermore, a drawback of the conventional structure of elastic switches is that each of the pair of band contacts is made of a continuous metal plate without holes. For this reason, the required switch operation force is already large, but
It has to become even bigger.

It is an object of the present invention to provide an elongated elastic switch. To achieve this purpose, an elastic switch is constructed in which a pair of band contacts are housed in an elastic housing in such a way that they are completely protected against external influences, and that the elastic housing can be removed without damage. It has the advantage of being inserted into the hollow chamber of.

To achieve the above object, the present invention has a structure in which a band switch main body has a pair of band contact tubes arranged in an elastic tube made of injection molded synthetic resin, and furthermore, the band switch main body has a flat base. Mounted in close proximity to a mounting block or retaining rail, the resilient tube has a curved surface spaced apart from its base, the curved surface engaging at least one web, which web hits an obstacle. When it comes into contact with the obstacle, it moves toward the band contact point in response to the direction of the compressive force applied to the obstacle.

As described above, according to the present invention, since the pair of easily damaged band contacts are stored in the elastic tube in advance, they are completely protected from external influences until they are slightly stretched by the elastic nozzle of the elastic switch. protected. Furthermore, even if a lateral force is applied to the elastic switch, this force is deflected approximately perpendicularly to the pair of band contacts, thereby ensuring reliable electrical contact of the band contacts at all times. It is honked. In the configuration of the present invention, it is desirable that the pair of band contacts be arranged parallel to the mounting surface. An elastic one with a pair of band contacts stored near the mounting part? Due to the placement of the
The closing operation of the pair of band contacts also occurs in other cases.

It is advantageous if the switch operating lip protruding from the curved surface of the elastic tube extends toward the pair of band contacts and has its end as close as possible to the band contacts. With this configuration, even if a substantially horizontal force acts on the elastic cylinder, a compressive force always acts on the pair of band contacts at a substantially right angle.

The first band contact, which is placed on the flat base of the elastic cylinder with some margin, has no holes at all, and is formed so that there are no protrusions on both sides. The second band contact, which is spaced apart from the other, has a number of slots arranged parallel to each other in the transverse or diagonal direction, separated by a web, and has a side facing the first band contact. There is a great advantage in having insulating bands on both continuous edges.

Preferably, the second band contact further has a central isthmus web as close as possible to the switch operating ring.

It is desirable that the diagonal slots are formed slightly wider than the diagonal webs existing between the diagonal slots. Further, it is desirable that the first diagonal web and the vertical webs at the center and both side edges have approximately the same width.

Since the strip contact which receives the switch operation force first has a hole, the force required to produce the opening and closing action is reduced. Since the insulating band is provided on a band contact having a hole, 2
Even if small relative lateral movements occur between the strip contacts, electrical shorts cannot occur.

In order to prevent short circuits between the contacts, which may occur due to bending of the elastic tube, an insulating band is provided towards the contact band with the hole. It is important that the two band contacts are arranged with some margin so that they can move relative to each other during opening and closing operations. However, since there is a risk of short circuit, certain restrictions are placed on the # movement in the 14 directions.

The central longitudinal web allows the switch 1+≠operation force to be transmitted to the pair of points 'ff+M without any hindrance and reliably.

Furthermore, the required switch operation force is small and the reliability of operation is guaranteed up to -11°C.

Furthermore, if the elastic cylinder is arranged within an auxiliary assembly member, and this auxiliary assembly member is housed in the hollow chamber of the elastic housing of the elastic switch, the advantages are significant. This embodiment V
According to C, the elastic cylinder is first fixed to the assembly auxiliary member,
This assembly aid is then drawn into the resilient housing and is therefore handled with greater care.

It is more advantageous to place the auxiliary assembly member to which the elastic cylinder metal is attached in the center of the elastic housing of the elastic switch.

Furthermore, it is more advantageous if the assembly auxiliary member is open on one side. In particular, it is more advantageous to open in the opposite direction to the attachment surface to the closure, that is, toward the edge of the opening to be closed.

In the embodiment using the above-mentioned assembly auxiliary member,
An elastic gap housing the strip switch body projects from the assembly auxiliary member and is provided as close as possible to the transverse web of the elastic nozzle of the elastic switch.

In another embodiment in which the upper TIC assembly f+1 auxiliary member is used for one time, the elastic gap is disposed deeply inside the assembly auxiliary member and protrudes from the transverse web of the elastic housing toward the elastic gap. The end of the switch operating lip is in close proximity to or in contact with the elastic tube.

In a further embodiment using the assembly f+ii 8 member described above, this assembly auxiliary member is placed internally on the buffer web.

In order for the band switch main body to operate without trouble against compressive forces applied from all directions, it is preferable that the slow release web be spaced apart from the elongated one-piece block by the hollow portion.

According to another embodiment of the invention, the actuating web, preferably of flat design, is arranged in a figure-seven shape from one transverse web to the transverse web of the piece, the other transverse web housing the strip switch body. The load can be applied to the elastic cylinder.

The above-mentioned beak web is located opposite the mounting block,
Preferably, the load is applied by longitudinal webs located close to the ends of the resilient housing.

As described above, according to the present invention, both ends of the V-shaped web having the radius R moving in the +41 direction are connected to the outwardly convex curved web, and the chair is linear, that is, Combined with flat transverse webs. The longitudinal web applies a load to the center of the transverse web in order to transmit externally applied switch operating forces. Therefore, even if the switch operation force is small or the switch operation stroke is small, the switch body opens and closes. The required switch operation stroke can be shortened to about 4 to 6-0. Furthermore, even after the opening/closing operation of the switch body has occurred,
It can be transformed considerably. That is, the subsequent deformation is very large. This is therefore very useful for overruns that occur in opening and closing doors or opening doors, ie before the motor is stopped or reversed.

In order to change the sensitivity of the band switch body, in particular, the switch operation stroke between the switch operation rib and/or the horizontal web and the elastic tube housing the band switch body must be changed between the elastic tube and the auxiliary assembly member. Add the supplementary pieces to the egg.

Obtaining good response characteristics to forces applied from almost every direction is ensured by arranging the strip switch bodies, one on each side of the central plane of the elastic switch.

In this configuration, the two strip switch bodies are preferably located on the mounting block or rail of the closure in order to provide good protection for the pair of strip contacts.

In the embodiment - having two strip switch bodies, the strip switch bodies are housed in an elongated hollow space provided in a projection from the mounting block, the projection having a pressure Integrated into the transmission web.

In other embodiments having two strap switch bodies, the strap switch bodies are housed in grooves on both sides of the mounting block. The rail of the closure fixed to the main body of the strip switch is also inserted into the groove.

In the elastic switch according to the invention, a part of the support web is provided on both sides of the elastic nozzle in parallel to the web that directly transmits pressure to the strip switch body, and this part of the support web is configured to transmit pressure directly to the main body of the strip switch. Since it is thinner than the direct transmitting web, the transmission of pressure mostly takes place through the direct transmitting web.

In order to make the elasticity of the elastic nosing of the elastic switch appropriate, that is, even if a small contact force is applied to the elastic nosing, in this case, at least the opening/closing operation of the switch will not occur. It is desirable that one, preferably two, hollow chambers are provided on the side remote from the mounting surface and arranged vertically.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 7.

As can be seen from FIG. 1, the strip switch main body 11 used in the elastic switch of the present invention has an approximately semicircular cross-section, and is particularly made of an injection-molded synthetic resin tube made of polyvinyl chloride. have The strip switch body 11 has a cross section consisting of a flat base (9) and a curved section 31, which base and the curved section 31 surround an elongated hollow chamber 33. A pair of flat upper and lower band contacts 15 and 16 are disposed on the base.

The upper and lower band contacts 15 and 16 are made from thin spring steel sheets and in the mortar-like embodiment have a width of 5 mm and a thickness of #''L' 0.5 tmtr. has.

The lower band contact 16 (shown as a single straight line in FIG. 1) adjacent to the base is continuous without any holes. However, the upper band contact 15 has a plurality of identically sized diagonal slots IO, as shown in FIG. 1A. A plurality of these diagonal slots 10 are arranged in parallel and separated by diagonal webs 9 having the same width.

On both side edges of the upper band contact 15, continuous longitudinal webs 8 are formed, to which an insulating band made of synthetic material is applied as an inseparable layer. These insulating strip openings abut the lower strip contact 16, but are not bonded. That is, the insulating band opening, the lower band contact 16 contacts the base (9) in a relatively movable manner.
) in relative movable contact.

The upper band contact 15 also has a central longitudinal web 7, as shown in FIG. 1A.

A switch operation lip 32 protrudes into the hollow chamber 33 from the catching surface 31, and the upper and lower band contacts 15 and l
Head towards d. However, the switch operation reply 32 is
It projects as close as possible to the central longitudinal web 7 of the upper band contact 15. As shown in FIG. 1, when a force F such as pressure is applied to the band switch body 11, the curved surface portion 31 deforms, and the switch operation lip 32 comes into contact with the upper band contact 15, This upper band contact 15 is elastically pressed against the lower band contact 16. As a result, the upper and lower band contacts 15 and 16 are electrically and temporarily electrically connected. Thus, when force F is removed, upper and lower band contacts 15 and 16 become % non-conducting.

The above upper and F section band contacts 15 and 16 are
A temperature of -30°C to +8°C is inside the cylinder consisting of
It is arranged with enough margin to allow it to operate freely over a temperature range of 0°C. When the band switch main body 11 is not deformed by any external force, the omnidirectional movement range of the upper and lower band contacts 15 and 16 is preferably at least 0.2 mm. Upper and lower band contacts 15
and 16 must not adhere to each other during injection molding. These upper and lower band contacts
15 and 16 must be adjustable in their mutual position so that they can be easily replaced even after injection molding.

Therefore, the upper and lower band contacts 15 and 16 are arranged with a margin within the cylinder consisting of the pad and the curved surface portion 31 so that they can move relative to each other within a predetermined range. If the upper and lower band contacts 15 and 16 are placed in the cylinder in this way, a necessary margin can be obtained, for example, to avoid short circuits caused by distortions due to the stress of the ridges.
Furthermore, the mutual movement is too large and the upper and lower band contacts 15
It is also possible to limit the degree of mutual movement so that a short circuit does not occur between and 16.

The movement of the upper and lower band contacts 15 and 16 is limited so that the edges of the lower band contact 16 do not enter between the insulating bands 34 on both sides (as this would likely lead to a short circuit). ing. Upper and lower band contacts 15
It is desirable that the insulating band 16 is not deformed by being compressed together. Therefore, the insulation band 34
Preferably, the material is made of a non-yielding synthetic material rather than foam rubber.

As can be seen in FIGS. 2 and 3, the resilient housing of the resilient switch of the present invention has a mounting block xl of approximately 190-shaped cross section. This mounting block measurement is for mounting surface 1
It has 8. This mounting surface 18 is attached to the closed #4 edge of a door or such barrel.

The V-shaped portion of the mounting block 280' is shown in FIG. 2 and has screws 3. ) installed by. Details of the C-shaped member 29 are shown in FIG. The elastic switch of the present invention can be pushed in the longitudinal direction of the C-shaped part 29, or
It is inserted into this C-shaped member 29 from the side opening of the C-shaped member z9. Regarding the latter method, a hollow part 36 in which an OC-shaped member 29, which will be described in detail later, is housed, and a sealing lip part 37 just outside of the hollow part 36, which will be described in detail later, have a C-shaped part @
Protect 29.

Since the structure is as described above, the elastic switch can be inserted into the C-shaped member 29 quickly and without any difficulty. To do this, do not freeze, for example:
Several phrase blocks that right 1-11 lower nose is C-shaped member 29
is inserted through the side opening of the C-shaped member 29 and placed under the inwardly directed flange of the right leg of the C-shaped member 29. Then, the block path is rotated counterclockwise around the identified right Q411 lower nose. This causes the left lower nose of the mounting block channel to be quickly pressed into position under the inwardly directed flange of the left leg of the C-shaped member 4. This work can be done, for example, if the oval hollow part is
It will be easier if it is formed in the area between the lower noses.

Elongated hollow chambers 13 and 14 are formed within the projections 38 and 39. These protrusions 38 and 39 are disposed on the side of the mounting block farthest from the mounting surface 18 and on both sides of the longitudinal center surface 17. 4%
Band switch bodies 11 and 1 shown in detail in Figure 1
2 are placed in hollow chambers 13 and 14, respectively.

The protrusions 38 and 39 are attached to the mounting surface 18 of the mounting block 28.
On the side furthest from the pressure transmitting webs 26 and 2
7 are integrated into each other. These pressure transmission webs 27 are also connected to transverse webs 40.

Both ends of this transverse web 40 are integrally connected to support webs 4 and 6.

The support web bottom 25 extends towards the mounting surface 18 and the sealing element 37 extends beyond the whisper web 40.
has. These sealing lips 37 are parallel to the pressure transmitting web aperture 27. However, the pair of sealing lips 37
Since the pressure transmitting webs are made thinner than the pressure transmitting webs and n
The signal is transmitted to the band switch bodies 11 and 12 via.

In FIG. 2, the upper end extensions of support webs U and b are connected by an intermediate transverse web 41 in the opposite position of the transverse web 40. In FIG. However, these supporting web words and 25
an upper end extension, an intermediate transverse web 41, and an end transverse web 4.
2 cooperate with each other to form a hollow chamber 19 having a circular cross section. A sealing lip 43 is provided at the distal end of the support web 5 and projects from the terminal transverse web 42 .

Since the elastic switch of the present invention is configured as described above, an elongated hollow chamber side is formed by the support web 25, the lateral web 4°, and the intermediate lateral web 41, and furthermore, the sealing lip portion 37, the mounting web 4o, the mounting block back, the pressure transmission webs 26 and n, the protrusions, S8 and 3
9, elongated hollow chambers 21 and 22, respectively, are formed parallel to each other. These hollow chambers 21J, 21, 22 and I, together with the elastic nature of the material of the elastic housing, explain the mode of operation of the invention. As shown in FIG. 2, if a force P is applied to this elastic switch, for example, during the closing operation of a closure to which a device incorporating this elastic switch is plated, the device will close the closure. , the support webs 11 and 5 first bend due to elastic deformation, so the band switch bodies 11 and 12 do not respond at first. Pressure transmission web and 27
When the force transmitted to exceeds the predetermined force threshold,
The band contacts 15 and 16 are brought into contact via the switch operation rib 32. This generates a warning signal, a stop signal and/or a reversal signal.

As shown in FIG. 2, when a lateral force Q is applied to the elastic switch of the present invention, first, the hollow chambers 19 and 2
0t - only the surrounding relatively soft elastic parts are deformed, so that the side of the support web 25 is subjected to a total compressive load and the force transmitted to the pressure transmission web n exceeds the predetermined force threshold; The band switch body 12't
? Operate the closing operation. On the other hand, a tensile load is applied to the other side of the support web as a whole, so only the tensile load is applied to the other side of the pressure transmission web, so the band switch main body 11 does not close.

Thus, a certain distance is provided between the strip switch bodies 11 and 12 such that a lateral force Q applied to the elastic switch of the invention causes a corresponding rotation or longitudinal movement of the pressure transmitting webs 26 and 27. Existence is important. However, if the band switch bodies 11 and 12 are electrically connected in parallel, the elastic switch will generate an electrical contact signal even if the band switch body 11 does not perform a closing operation.

As shown in FIG. 2, when a lateral force R is applied to the resilient switch of the present invention, the opposite occurs when a lateral force Q is applied. That is, the band switch main body 11 is closed via the pressure transmission web. but,
Since only a tensile load acts on the pressure transmission web 27, the band switch body 12 does not close.

In the second embodiment shown in FIG.
Equivalent parts in the figures are designated by the same reference numerals. As can be seen from FIG. 4, the band switch bodies 11 and 12 are
C-shaped grooves 13a and 14 (Z) located on both sides and open outward are housed within.

In this case, the semicircular portion 31 is in contact with the side wall of the groove 13α that is farther from the surface 18. The flat paces 30 of the strip switch bodies 11 and 12 are connected to the C-shaped member 29.
It is fixed to the inward flanges 291 on both sides of. It is desirable that these pastes 3o are fixed with an adhesive.

The above C-shaped member 2911″1., the door opens with the screw 35,
It is fixed to the sliding door or the closing edge of the rotary furnace (not shown).

The C-shaped member 29 tightens the mounting block so that it is fixed against the forces P, Q, and M shown in FIG.

As can be seen in FIG. 4, the ends of the support webs U and 25, which define the width on the side of the cavity, are connected directly to the mounting block channel. Grooves 13α and 14 (L are spaced apart by a distance sufficient to provide the necessary amount of elastic deformation to operate the strip switch bodies 11 and 12 when force PQ or R is applied to support web members and grooves 25). It is located directly below the terminal end.

According to the second embodiment shown in FIG. 4, the assembly of the band switch bodies 11 and 12 is extremely simple, and even if the band switch bodies 11 and 12 are damaged, they can be replaced at any time. .

The elastic switches according to the first and second embodiments have the above-mentioned "0 position", so the response is 41.
The force 11 on the surface of the elongated section comprising the supporting webs 2/1 and 25 and the end transverse web 42 has little bearing on the angle of the compressive load exerted thereon. Furthermore, it is also possible to use the strip switch bodies 11 and 12 as a mounting block for the elastic switch so that the strip switch bodies 11 and 12 are protected from external shadows IIC. By doing so, the mechanical damage to the switch bodies 11 and 12 themselves can be largely prevented, and the switch operation stroke can be determined.

In particular, in the sentence types above, what follows "Furthermore..."
Elastic deformation occurs only when the band switch body is completely completely on at least three sides. Therefore, the device does not respond immediately when the resilient switch contacts the closure surface.

The elastic switch and the band switch main body therein operate almost regardless of their posture.

Since a reliable pressure transmission path to the band contacts of the band switch bodies is ensured, only relatively small forces are required to operate these band switch bodies.

The elastic switch of the present invention can be used as a protective device attached to highly dangerous machinery, such as a press machine, to issue a stop signal or a reversal signal when an operator's hand is caught. .

In the third embodiment shown in FIG. 5, the band switch main body 11 is arranged at the center of the assembly auxiliary member 112.

This assembly auxiliary member 112 has a substantially rectangular cross-section, and has lateral protrusions on both sides of the lower part for increasing the mounting area. The assembly section 112 has a KU cedar groove 113 on the side farthest from the mounting block 120.

The width of this groove 113 is almost equal to the width of the band switch body 11. However, on the other hand, the depth of the groove 113 is considerably greater than the height of the strip switch body 11. in this way,
The main body of the band switch 11 is disposed on the bottom surface of the i4113 while maintaining operational reliability.The main body of the band switch 11 is glued to the bottom surface of the groove 113. Band switch body 11 and groove 113
It can be inserted between the bottom of the by this,
The vertical position of the band switch body 11 within the groove 113 can be adjusted.

The assembly auxiliary member 112 is arranged on the horizontal web 119 of the elastic switch according to the third embodiment. Mounting block 1 by lateral web 119id, hollow chamber 118
It is separated by 20. The mounting block 120 is fitted into a metal C-shaped member 142 having an opening on one side.

Since the assembly auxiliary member 112 is arranged in such a positional relationship, even in the case of an operation in which a considerable amount of undesirable damage to the band switch body 11 is removed in advance, a certain degree of damage can be avoided. A buffering effect is ensured.

The switch operation lip 114 integrally connected to the relatively thin horizontal web 121 of the elastic switch according to the third embodiment is arranged in a groove 113 so as to be slightly separated from the strip switch body 11.
It extends into this groove 113 from above.

From the proximal end of the switch operation lip 114, that is,
Since the switch operating lip 114 is integrated into the transverse web 121, the operating webs 122 and 123 protrude in a V-shape that widens away from the mounting block 120. Therefore, these operation webs 122 and 1
The tips of 23 are connected to both side walls of the elastic switch. A beak web 124 is disposed between the connecting points between the tips of these operating webs 122 and 123 and both side walls. This horizontal web 124 has a vertical web 125 at its center.
It receives the load applied from. This longitudinal web 125 is integrally connected to the end wall 136 of the elastic switch.

The elastic switch is completely shielded from the outside by side walls 126 and 127. Operation webs 122 and 12
Around 3, the side walls 126 and 127 are formed by thin deformable webs.

A section 128 is provided at one end of the end wall 136 and extends further upward from the tip of the side wall 127. The outer surface of the sealing lip 128 is slightly curved so as to be convex. However, this sealing lip 1
28 extends close to the longitudinal center plane 140 of the resilient switch. The distal end of the sealing body 128 is inclined toward the longitudinal center plane 140 due to the stress t-± with respect to the lateral forceps and Q. C
The shaped member 142 is attached to, for example.

The operation mode of the elastic switch according to the third embodiment will be explained below.

As shown in FIG. 5, when a downward force F is applied along the longitudinal center plane 140, the sealing shield 128
It curves toward the longitudinal center plane 140 . As a result, most of the force is transmitted towards the central longitudinal web 125 within the upper chamber 139. The central longitudinal web 125 thus moves towards the C-shaped member 142. As a result, the transverse web 124 is bent to project downwardly, thereby drawing the entire operating webs 122 and 123 towards the longitudinal center plane 140. Therefore, the switch operating web 114 moves downward and the strip switch body 1
Press 1. This provides the desired electrical continuity.

A similar movement occurs when a lateral force Q or R is applied, as shown in FIG. That is, in this case, either one of the operating webs 122 or 1223 moves closer to the longitudinal center plane 140, which causes the switch operating web 114 to move downward and move the strip switch body ll. Press.

In this way, the initiation of switch operation by the band switch body 11 is almost independent of the direction of the force and is highly reliable. Moreover, the sensitivity of the start of switch operation is guaranteed only by the 111 band switch bodies. Operation web 1
Side walls 126 and 127, which are thinner than 22 and 123, are
Since only these are curved so as to be outwardly convex, movement of the operating webs 122 and 123 is not hindered.

All of the above forces F are not transmitted directly downwards, but by means of longitudinal webs 125 to actuating webs 122 and 12.
3'@: It is converted into a force that moves as a lever.

As is clear from FIG. 5, the band switch main body 11 is located at a certain distance from the mounting block 120. It is thus located within the elastic switch at such a depth that it is sufficiently protected against external influences.

The hollow chamber 118 forms a buffer zone, and the width of this buffer zone is
It depends on the height of the mounting block 120.

In the fourth embodiment shown in FIG. 6, equivalent parts to those in FIG. 5 are designated by the same reference numerals. In this fourth embodiment, the hollow chamber 11 that existed in the third embodiment is
8 does not exist. That is, the assembly auxiliary member 112 is
It is located directly on the mounting block 120. This makes the elastic switch even more compact. A hollow hole 120' having an oval cross section is formed in the central axis of the mounting block 120, and this hollow hole 120' increases the elasticity of the mounting block 120, so it is suitable for holding rails such as C-shaped members. It becomes easy to insert the mounting block 120.

The horizontal web 121 has a ■-shaped notch 121' at its center.
It is divided into two by. For this reason, the operating webs 122 and 123 effectively replace the switch operating rib 1
It is the same as being connected to 14. As a result, the required switch operation force can be reduced.

In order to further reduce the required switch operation force, the hollow chamber 139 of the third embodiment is omitted, and the tip of the vertical web 125 protruding from the horizontal web 124 is made a free end without being connected to other parts.

The free end of the longitudinal web 125 is connected to the apex 12 of an arcuate sealing lip 128 spaced relative to the free end of the longitudinal web 125.
It is opposite to 8'. Vertex portion 128' of dense vibration main portion 128
exists in the longitudinal center plane, and the longitudinal webs 125 also protrude into the longitudinal center plane.

The assembly auxiliary member 112 is housed within the hollow chamber 135. This hollow chamber 135 is formed by the transverse webs 119 and 12
1, one side wall 126 and 127, and switch operation rib 114
It is formed by.

The assembly auxiliary member 112 is directly fixed to the transverse web 119 and is installed at a considerable distance from the side walls 126 and 127.

In the fifth embodiment shown in FIG.
This corresponds to the fourth embodiment shown in the figure. However, this fifth
In the embodiment, there is no fourth switch. Instead, the band switch main body 11 protrudes from the assembly auxiliary member 112 in a direction away from the mounting block 120, and there is a slight gap between the apex of the band switch main body 11 and the horizontal web 121. are doing. Therefore, the band switch body 11 is operated directly by the transverse web 121VC via the operating webs 122 and 123t.
