Description

Technical Field

[0001] The invention relates to a movable foot pad, in particular to a movable foot pad suitable for a bearing seat. Background Art

[0002] Chairs or stools are the most frequently used products in daily life and usually there will be no problems. However, in quiet meeting rooms, cafes, and important public places, the noise generated by the movement of chairs or stools can cause distress, irritation, and embarrassment, thus affecting people's mood.

[0003] Therefore, in order to make chairs or stools easy to move without making noise, several assembled foot pads have appeared on the market. For example: soft rubber cover type foot pads, which can have a silent effect but are not easy to move. Or, for example: hard rubber fixed type foot pads, which can slide but require greater force and are not completely silent. Therefore, the above two types of foot pads are not good in terms of user experience and cannot take into account both silence and convenience of movement. Summary of the invention

[0004] The main purpose of the present invention is to provide a movable foot pad. By installing the movable foot pad of the present invention on the supporting feet of the support base, the support base can be easily moved forward and backward when there is no specific weight, and the support base will automatically brake and be fixed when there is a specific weight, making the support base easier to move and noiseless, especially in places that require quietness, which can better reflect the importance of the movable foot pad of the present invention.

[0005] In order to achieve the above-mentioned purpose, the movable foot pad of the present invention is installed on a supporting foot of a supporting seat, and includes an outer shell, a movable inner sleeve, an elastic member and a roller. A fixed connecting member is fixedly provided on the outer side of the outer shell, and a supporting portion is provided on the inner side and an outer shell accommodating space is provided. The movable inner sleeve is slidably arranged in the outer shell accommodating space and can slide relative to the outer shell so that the movable inner sleeve slides to an active position or a braking position. The elastic member is clamped between the outer shell and the movable inner sleeve, and the roller is pivotally arranged on the movable inner sleeve. When the movable inner sleeve is located at the active position, the roller is spaced apart from the supporting portion by an active distance, and when the movable inner sleeve is located at the braking position, the roller abuts against the supporting portion.

[0006] The abutting portion may be an arc-shaped structure to correspond to the outer contour of the roller, so that when in contact, they can fit completely to achieve a braking effect.

[0007] The above mentioned active distance may be 1 mm.

[0008] Another movable foot pad of the present invention is installed on a supporting foot of a supporting seat, and includes an outer shell, a movable inner sleeve, an elastic member and a roller. A fixed connecting member is fixedly provided on the outer side of the outer shell, and an outer shell accommodating space is provided on the inner side. The movable inner sleeve is slidably arranged in the outer shell accommodating space, and can slide relative to the outer shell so that the movable inner sleeve slides to an active position or a receiving position. The elastic member is clamped between the outer shell and the movable inner sleeve, and the roller is pivotally arranged on the movable inner sleeve. When the movable inner sleeve is located at the active position, the roller protrudes from the lower edge of the outer shell, and when the movable inner sleeve is located at the receiving position, the roller does not protrude from the lower edge of the outer shell and is accommodated in the outer shell accommodating space.

[0009] The movable foot pad may further include a set of appearance parts arranged on the outer shell.

[0010] The movable foot pad may further include a locking nut threaded on the fixed connection member, wherein the locking nut is located between the appearance member and the support leg to ensure that the movable foot pad is securely locked on the support leg.

[0011] The fixing connection member may be a fixing screw for locking the movable foot pad on the supporting foot.

[0035] See also Figure 1 , is a three-dimensional diagram of a support base equipped with a movable foot pad according to the first embodiment of the present invention. As shown in the figure, the movable foot pad 1a of the present invention is installed on each supporting leg 101 of a support base 10. In this embodiment, the support base 10 is a chair or stool for people to sit on, but it is not limited to this, and can also be any vehicle that can carry heavy objects, so that the support base 10 can be easily moved forward and backward when there is no specific weight, and the support base 10 will automatically brake and fix when there is a specific weight, so that the support base 10 can be more convenient to move and no noise, especially in places that require quietness, which can better reflect the importance of the movable foot pad 1a of the present invention.

[0036] See also Figure 2 and Figure 3 , which are respectively a stereoscopic view and an exploded view of a movable foot pad according to a first embodiment of the present invention. The figure shows a movable foot pad 1a, which includes an outer shell 2, a movable inner sleeve 3, an elastic member 4, two rollers 5, an appearance member 6 and a locking nut 7.

[0037] In this embodiment, the housing 2 is made of plastic material, and a fixing member 21 is fixedly disposed on the outer side of the housing 2. The fixing member 21 of this embodiment is a fixing screw, which is used to lock the movable foot pad 1a to the supporting foot 101, and the inner side of the housing 2 has a supporting portion 22 (such as Figure 4AAs shown in the figure, a housing space 20 is provided in the outer shell. The abutting portion 22 of the present embodiment is an arc-shaped structure, which can correspond to the outer contour of the roller 5, so that when in contact, it can fit completely to achieve a braking effect. The movable inner sleeve 3 is slidably disposed in the housing space 20 of the outer shell, and can slide relative to the outer shell 2, so that the movable inner sleeve 3 slides to an active position or a braking position. The elastic member 4 is clamped between the outer shell 2 and the movable inner sleeve 3 to provide the movable inner sleeve 3 with an elastic restoring force to restore it from the braking position to the active position. The two rollers 5 are pivotally disposed on the movable inner sleeve 3 by a pivot 31, so that the movable foot pad 1a can move along the rolling direction of the roller 5. The appearance member 6 of the present embodiment is made of aluminum material and is sleeved on the outer shell 2 to improve the structural rigidity and visual aesthetics. In addition, the locking nut 7 is screwed on the fixed connecting member 21 and is located between the appearance member 6 and the supporting foot 101. Thus, after the user manually locks the fixed connector 21 to the support leg 101 , the user can use a wrench or other locking tools to turn the locking nut 7 to ensure that the movable foot pad 1 a is firmly locked to the support leg 101 .

[0038] See also Figure 4A and Figure 4B , which are cross-sectional views of the movable foot pad in the first embodiment of the present invention in the active state and the braking state, respectively. Figure 4A As shown, when the bearing seat 10 does not bear a specific weight, the elastic member 4 has not been compressed, so that the movable inner sleeve 3 can be located in the movable position. At this time, the roller 5 and the abutment portion 22 are separated by an active distance D. The active distance D in this embodiment is 1 mm, but it is not limited to this and can also be other values. Therefore, the two rollers 5 are not restricted by the abutment portion 22 and can easily move forward and backward. Figure 4B As shown, when the bearing seat 10 carries a certain weight, the elastic member 4 is compressed, so that the movable inner sleeve 3 can be located in the braking position. At this time, the roller 5 abuts against the abutting portion 2 without a movable distance D, so that the arc-shaped structures of the two rollers 5 and the abutting portion 2 fit each other and cannot move forward and backward. Among them, the floating load-bearing capacity of each roller 5 is about 5 to 6 kilograms, so when each roller 5 exceeds this weight, the movable inner sleeve 3 will be located in the braking position and cannot move forward and backward. In addition, the total load-bearing capacity of each roller 5 is about 50 kilograms, and it may be damaged if it exceeds this weight.

[0039] See also Figure 5A and Figure 5B, which are cross-sectional views of the movable foot pad in the second embodiment of the present invention in the active state and the accommodated state, respectively. The figure shows another movable foot pad 1b, whose basic structure is the same as that of the first embodiment, and the main difference is that the braking method is slightly different from that of the first embodiment. In this embodiment, the outer shell 2' is made of plastic material, and a fixed connecting member 21 is fixedly arranged on the outer side of the outer shell 2'. The fixed connecting member 21 of this embodiment is a fixing screw, which is used to lock the movable foot pad 1b to the supporting foot 101, and a shell accommodating space 20' is provided on the inner side of the outer shell 2', and this embodiment does not have a supporting part, and it is notified. The movable inner sleeve 3' is slidably arranged in the outer shell accommodating space 20', and can slide relative to the outer shell 2', so that the movable inner sleeve 3' slides to an active position or a accommodated position. The elastic member 4' is sandwiched between the outer shell 2' and the movable inner sleeve 3', and is used to provide the movable inner sleeve 3' with elastic restoring force so that it can return from the accommodated position to the active position. The two rollers 5 are pivotally mounted on the movable inner sleeve 3' so that the movable foot pad 1b can move along the rolling direction of the rollers 5. The appearance member 6' of the present embodiment is made of aluminum material and is sleeved on the outer shell 2' to improve the structural rigidity and visual aesthetics. Among them, since the present embodiment needs to accommodate the two rollers 5 in the outer shell accommodating space 20', both the movable inner sleeve 3' and the appearance member 6' have a higher structural design compared with the first embodiment to increase the accommodating space. In addition, the locking nut 7 is screwed on the fixed connecting member 21 and is located between the appearance member 6' and the supporting leg 101. Thereby, after the user manually locks the fixed connecting member 21 to the supporting leg 101, the locking nut 7 can be turned with a wrench or other locking tools to ensure that the movable foot pad 1b is firmly locked on the supporting leg 101.

[0040] like Figure 5A As shown, when the bearing seat 10 does not bear a specific weight, the elastic member 4' has not been compressed, so that the movable inner sleeve 3' can be located in the movable position. At this time, the roller 5 protrudes from the lower edge of the outer shell 2', so it can move forward and backward easily. Figure 5B As shown, when the bearing seat 10 bears a certain weight, the elastic member 4' is compressed, so that the movable inner sleeve 3' is located at the receiving position. At this time, the roller 5 does not protrude from the lower edge of the outer shell 2' and is contained in the outer shell containing space 20', so the outer shell 2' mainly bears the weight and cannot move forward and backward. Among them, the floating load of each roller 5 is about 5 to 6 kilograms, so when each roller 5 exceeds this weight, the roller 5 will retract into the outer shell containing space 20' of the outer shell 2', and the outer shell 2' will touch the ground and cannot move forward and backward. In addition, the total load of each roller 5 is about 50 kilograms, and it may be damaged if it exceeds this weight.
